PRELIMINARY — SUBJECT TO COMPLETION, DATED JANUARY 18, 2019

MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

                , 2019

Dear Shareholders ofII-VI Incorporated and Stockholders of Finisar Corporation:

II-VI Incorporated(“II-VI”) and Finisar Corporation (“Finisar”) have entered into an Agreement and Plan of Merger, dated as of November 8, 2018 (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, Mutation Merger Sub Inc., a Delaware corporation and wholly owned subsidiary ofII-VI, will be merged with and into Finisar, and Finisar will continue as the surviving corporation in the merger and a wholly owned subsidiary ofII-VI (the “Merger”).

If the Merger is consummated as described in the accompanying joint proxy statement/prospectus, Finisar stockholders will be entitled to receive, at their election, consideration per share of common stock of Finisar (the “Finisar Common Stock”) consisting of (i) $26.00 in cash, without interest (subject to the proration adjustment procedures described in the accompanying joint proxy statement/prospectus, the “Cash Election Consideration”), (ii) 0.5546 validly issued, fully paid and nonassessable shares ofII-VI common stock (the shares, the“II-VI Common Stock,” and the consideration, subject to the proration adjustment procedures described in the accompanying joint proxy statement/prospectus, the “Stock Election Consideration,” respectively), or (iii) a combination of $15.60 in cash, without interest, and 0.2218 validly issued, fully paid and nonassessable shares ofII-VI Common Stock (the “Mixed Election Consideration,” and, together with the Cash Election Consideration and the Stock Election Consideration, the “Merger Consideration”). If no election is made as to a share of Finisar Common Stock, the holder of that share will receive the Mixed Election Consideration. The Cash Election Consideration and the Stock Election Consideration are subject to proration adjustment pursuant to the terms of the Merger Agreement such that the aggregate Merger Consideration will consist of approximately 60% cash and approximately 40%II-VI Common Stock (with theII-VI Common Stock valued at the closing price as of November 8, 2018), as further described under the heading “The Merger Agreement — Merger Consideration” beginning on page 140 of the accompanying joint proxy statement/prospectus.

Based on the closing price forII-VI Common Stock on the Nasdaq Global Select Market on January 17, 2019, the most recent practicable date for which such information was available, the Stock Election Consideration represented approximately $18.56 in value per share of Finisar Common Stock (before giving effect to any proration adjustment), and the Mixed Election Consideration represented approximately $23.02 in value per share of Finisar Common Stock. The Cash Election Consideration represents a premium of approximately 37.7% over the closing price for Finisar Common Stock on the Nasdaq Global Select Market on November 8, 2018 (before giving effect to any proration adjustment). The value of the Stock Election Consideration and Mixed Election Consideration will fluctuate based on the market price ofII-VI Common Stock until the completion of the Merger. Shares ofII-VI Common Stock are traded on the Nasdaq Global Select Market under the ticker symbol “IIVI,” and shares of Finisar Common Stock are traded on the Nasdaq Global Select Market under the ticker symbol “FNSR.” We urge you to obtain current market quotations for the shares ofII-VI Common Stock and Finisar Common Stock.

Based on the number of shares of Finisar Common Stock outstanding as of                , 2019, and the treatment of shares of Finisar Common Stock and Finisar equity awards in the Merger, and assuming no conversions of the Finisar Convertible Notes,II-VI expects to issue approximately            million shares ofII-VI Common Stock to holders of Finisar Common Stock and Finisar equity awards upon completion of the Merger. The actual number of shares ofII-VI Common Stock to be issued upon completion of the Merger will be determined at the completion of the Merger based on, among other things, the number of shares of Finisar

Common Stock outstanding at that time. Based on the number of shares of Finisar Common Stock outstanding as of                , 2019, and the number of shares ofII-VI Common Stock outstanding as of                , 2019, it is expected that, immediately after completion of the Merger, former holders of Finisar Common Stock and Finisar equity awards will own approximately     % of the outstanding shares ofII-VI Common Stock.

At the special meeting ofII-VI shareholders described in the accompanying joint proxy statement/prospectus (the“II-VI Special Meeting”),II-VI shareholders will be asked to consider and vote on the following matters:

• a proposal to approve the issuance ofII-VI Common Stock in connection with the Merger (the “Share Issuance Proposal”); and

• a proposal to approve adjournments of theII-VI Special Meeting, if necessary or appropriate, including to solicit additional proxies if there are not sufficient votes to approve the Share Issuance Proposal (the“II-VI Adjournment Proposal”).

Approval of the Share Issuance Proposal requires the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast (assuming a quorum is present). This vote will satisfy the vote requirements of Listing Rule 5635(d) of the Nasdaq Stock Market with respect to the Share Issuance Proposal. Approval of theII-VI Adjournment Proposal requires the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast, whether or not a quorum is present.

At the special meeting of Finisar stockholders described in the accompanying joint proxy statement/prospectus (the “Finisar Special Meeting”), Finisar stockholders will be asked to consider and vote on the following matters:

• a proposal to adopt the Merger Agreement (the “Merger Proposal”);

• a proposal to approve adjournments of the Finisar Special Meeting, if necessary or appropriate, including to solicit additional proxies if there are insufficient votes at the time of the Finisar Special Meeting to approve the Merger Proposal (the “Finisar Adjournment Proposal”); and

• a proposal to approve, bynon-binding, advisory vote, certain compensation that may be paid or become payable to Finisar’s named executive officers in connection with the Merger contemplated by the Merger Agreement and the agreements and understandings pursuant to which such compensation may be paid or become payable (the “Compensation Proposal”).

Approval of the Merger Proposal requires the affirmative vote of holders of a majority of the outstanding shares of Finisar Common Stock. Approval of the Finisar Adjournment Proposal requires the affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting. Approval of the Compensation Proposal requires the affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting.

The Merger cannot be completed unless, among other things,II-VI shareholders approve the Share Issuance Proposal and Finisar stockholders approve the Merger Proposal.Your vote is very important, regardless of the number of shares you own.Even if you plan to attend theII-VI Special Meeting or the Finisar Special Meeting, as applicable, in person, please complete, sign, date and return, as promptly as possible, the enclosed proxy or voting instruction card in the accompanying prepaid reply envelope or submit your proxy by telephone or the Internet prior to theII-VI Special Meeting or Finisar Special Meeting, as applicable, to ensure that your shares will be represented at theII-VI Special Meeting or the Finisar Special Meeting, as applicable, if you are unable to attend. If you hold your shares in “street name” through a bank, brokerage firm or other nominee, you should follow the procedures provided by your bank, brokerage firm or other nominee to vote your shares.

After careful consideration, theII-VI board of directors unanimously approved and declared advisable the Merger Agreement and the other transactions contemplated thereby, including the Merger

and the issuance of shares ofII-VI Common Stock issuable in connection with the Merger, and determined that the terms of the Merger Agreement, the Merger and the other transactions contemplated thereby are fair to and in the best interests ofII-VI and its shareholders. TheII-VI board of directors accordingly unanimously recommends thatII-VI shareholders vote “FOR” each of the Share Issuance Proposal and theII-VI Adjournment Proposal.

After careful consideration, the Finisar board of directors, by unanimous vote, approved and declared advisable the Merger Agreement and the other transactions contemplated thereby, including the Merger, and determined that the terms of the Merger Agreement, the Merger and the other transactions contemplated thereby are fair to and in the best interests of Finisar and its stockholders. The Finisar board of directors accordingly recommends that Finisar stockholders vote “FOR” each of the Merger Proposal, the Finisar Adjournment Proposal and the Compensation Proposal. In considering the recommendation of the Finisar board of directors, you should be aware that directors and executive officers of Finisar have certain interests in the Merger that may be different from, or in addition to, the interests of Finisar stockholders generally. See the sections entitled “Finisar Proposal No. 3—Non-Binding, Advisory Vote on Merger-Related Compensation for Finisar’s Named Executive Officers” beginning on page 189of the accompanying joint proxy statement/prospectus and “Interests of Finisar’s Directors and Executive Officers in the Merger” beginning on page166of the accompanying joint proxy statement/prospectus for a more detailed description of these interests.

We urge you to read the accompanying joint proxy statement/prospectus, including the annexes and the documents incorporated by reference, carefully and in its entirety.In particular, we urge you to read carefully the section entitled “Risk Factors” beginning on page 48 of the accompanying joint proxy statement/prospectus.

On behalf of the respective boards of directors ofII-VI and Finisar, thank you for your consideration and continued support.

Sincerely,

Francis J. Kramer	Robert N. Stephens

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETINGS

The following questions and answers are intended to briefly address some commonly asked questions regarding the Merger and matters to be addressed at the Special Meetings. These questions and answers may not address all questions that may be important toII-VI shareholders and Finisar stockholders. Please refer to the section entitled “Summary” beginning on page 20 of this joint proxy statement/prospectus and the more detailed information contained elsewhere in this joint proxy statement/prospectus, the annexes to this joint proxy statement/prospectus and the documents referred to in this joint proxy statement/prospectus, which you should read carefully and in their entirety. You may obtain the information incorporated by reference into this joint proxy statement/prospectus without charge by following the instructions under the section entitled “Where You Can Find More Information” beginning on page 223 of this joint proxy statement/prospectus.

Q: Why am I receiving this joint proxy statement/prospectus and what am I being asked to vote on?

A: On November 8, 2018,II-VI, Merger Sub and Finisar entered into the Merger Agreement that is described in this joint proxy statement/prospectus. A copy of the Merger Agreement is attached asAnnex A to this joint proxy statement/prospectus and is incorporated by reference herein. In order to complete the Merger, among other things,II-VI shareholders must approve the Share Issuance Proposal and Finisar stockholders must approve the Merger Proposal.

II-VI is holding theII-VI Special Meeting to obtain the requisite approval of its shareholders for the Share Issuance Proposal. The Merger cannot be completed unless, among other things, the Share Issuance Proposal receives the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast (assuming a quorum is present). In addition,II-VI shareholders also will be asked to approve theII-VI Adjournment Proposal.

Finisar is holding the Finisar Special Meeting to obtain the requisite approval of its stockholders for the Merger Proposal. The Merger cannot be completed unless, among other things, the Merger Proposal receives the affirmative vote of holders of a majority of the outstanding shares of Finisar Common Stock. In addition, Finisar stockholders also will be asked to approve the Finisar Adjournment Proposal and the Compensation Proposal.

This joint proxy statement/prospectus serves as a proxy statement ofII-VI, a proxy statement of Finisar and a prospectus ofII-VI in connection with the issuance of shares ofII-VI Common Stock as part of the aggregate Merger Consideration (as defined below).

Your vote is very important. We encourage you to complete, sign, date and submit a proxy card to vote your shares ofII-VI Common Stock or Finisar Common Stock, as applicable, as soon as possible.

For more information regarding theII-VI Special Meeting, the Share Issuance Proposal, and theII-VI Adjournment Proposal, see the section entitled “Information About theII-VI Special Meeting” beginning on page 71 of this joint proxy statement/prospectus. For more information regarding the Finisar Special Meeting, the Merger Proposal, the Finisar Adjournment Proposal, and the Compensation Proposal, see the section entitled “Information About the Finisar Special Meeting” beginning on page 65 of this joint proxy statement/prospectus.

Q: What will happen in the Merger?

A: If each of the requisite conditions to closing under the Merger Agreement is satisfied or waived, Merger Sub will merge with and into Finisar in the Merger, and Finisar will continue as the surviving corporation, and become a wholly owned subsidiary ofII-VI. Following the effective time of the Merger (the “Effective Time”), Finisar Common Stock will be delisted from the Nasdaq Global Select Market, deregistered under the Exchange Act and cease to be publicly traded. See the section entitled “The Merger Agreement — Structure and Effects of the Merger” beginning on page 139 of this joint proxy statement/prospectus and the Merger Agreement attached asAnnex A to this joint proxy statement/prospectus for more information about the Merger.

1

Q: What will Finisar stockholders receive if the Merger is completed?

A: At the Effective Time, each outstanding share of Finisar Common Stock (other than any (i) shares held by a Finisar stockholder who is entitled to demand, and has properly demanded, appraisal for such shares (“Dissenting Stockholder Shares”) and (ii) shares owned byII-VI or Finisar or any of their wholly owned subsidiaries (“Excluded Shares”)), will be converted into the right to receive, at the election of the holder of such share of Finisar Common Stock, consideration consisting of (i) $26.00 in cash, without interest (subject to the proration adjustment procedures described in this joint proxy statement/prospectus, the “Cash Election Consideration”), (ii) 0.5546 validly issued, fully paid and nonassessable shares ofII-VI Common Stock (subject to the proration adjustment procedures described in this joint proxy statement/prospectus, the “Stock Election Consideration”), or (iii) a combination of $15.60 in cash, without interest, and 0.2218 validly issued, fully paid and nonassessable shares ofII-VI Common Stock (the “Mixed Election Consideration,” and, together with the Cash Election Consideration and the Stock Election Consideration, the “Merger Consideration”). If no election is made as to a share of Finisar Common Stock, the holder of that share will receive the Mixed Election Consideration.

If you otherwise would be entitled to receive a fractional share ofII-VI Common Stock as part of your Merger Consideration, you will receive cash in lieu of the fractional share ofII-VI Common Stock to which you would otherwise be entitled, and you will not be entitled to dividends, voting rights or any other rights in respect of such fractional share. For more information regarding allocation and proration procedures, see the section entitled “The Merger Agreement — Merger Consideration” beginning on page 140 of this joint proxy statement/prospectus.

Because the exchange ratios for the shares ofII-VI Common Stock that will be issued in the Merger as part of the Stock Election Consideration and the Mixed Election Consideration are fixed and there will be no adjustment to such exchange ratios, the aggregate value of the Merger Consideration received by Finisar stockholders who receiveII-VI Common Stock as Merger Consideration will depend on the then-current market price of shares ofII-VI Common Stock at the Effective Time. As a result, the value of the Merger Consideration that Finisar stockholders will receive in the Merger could be greater than, less than, or the same as, the value of such Merger Consideration on the date of this joint proxy statement/prospectus or at the time of the Finisar Special Meeting.

For more information regarding the Stock Election Consideration, Cash Election Consideration, or Mixed Election Consideration, as applicable, to be provided to Finisar stockholders, see the section entitled “The Merger Agreement — Merger Consideration” beginning on page 140 of this joint proxy statement/prospectus. For more information regarding election mechanics, see the sections entitled “The Merger Agreement — Election Procedures” beginning on page 142 of this joint proxy statement/prospectus and “The Merger Agreement — Exchange Procedures” beginning on page 143 of this joint proxy statement/prospectus.

Q: What will holders of Finisar Stock Options receive if the Merger is completed?

A: At the Effective Time, each option granted pursuant to Finisar’s 2005 Stock Incentive Plan (each, a “Finisar Stock Option”) (or portion thereof) that is outstanding and unexercised will be cancelled and terminated and converted into the right to receive an amount of Mixed Election Consideration that would be payable to a holder of such number of shares of Finisar Common Stock equal to the quotient of (i) the product of (a) the excess, if any, of $26.00 over the exercise price per share of such Finisar Stock Option multiplied by (b) the number of shares of Finisar Common Stock subject to such Finisar Stock Option,divided by (ii) $26.00 (the “Net Option Shares”). Each Finisar Stock Option that is outstanding and unexercised as of immediately prior to the Effective Time with an exercise price per share that is in excess of $26.00 will be cancelled and extinguished without any present or future right to receive the Merger Consideration or any other payment.

For more information regarding the treatment of holders of Finisar Stock Options, see the section entitled “The Merger Agreement — Treatment of Finisar Employee Stock Plans — Stock Options” beginning on page 144 of this joint proxy statement/prospectus.

Q: What will holders of Finisar Restricted Stock Units receive if the Merger is completed?

A: As of the Effective Time, each restricted stock unit granted pursuant to Finisar’s 2005 Stock Incentive Plan (each, a “Finisar Restricted Stock Unit”) (or portion thereof) that is outstanding and subject to a performance-based vesting condition that relates solely to the value of Finisar Common Stock will, to the extent such Finisar Restricted Stock Unit vests in accordance with its terms in connection with the Merger (the “Participating RSUs”), be cancelled and extinguished and converted into the right to receive the Cash Election Consideration, the Stock Election Consideration or the Mixed Election Consideration at the election of the holder of such Participating RSUs, subject to the proration adjustment procedures described in this joint proxy statement/prospectus (as applicable, the “Cash Election RSUs,” the “Stock Election RSUs” or the “Mixed Election RSUs”).

As of the Effective Time, each Finisar Restricted Stock Unit (or portion thereof) that is subject to a performance-based vesting condition that relates solely to the value of Finisar Common Stock but does not vest in accordance with its terms in connection with the Merger will be cancelled and extinguished without any right to receive the Merger Consideration or any other payment.

At the Effective Time, each Finisar Restricted Stock Unit (or portion thereof) that is outstanding and unvested and does not vest in accordance with its terms in connection with the Merger and is either (x) subject to time-based vesting requirements only or (y) subject to a performance-based vesting condition other than the value of Finisar Common Stock will be assumed byII-VI (each, an “Assumed RSU”). Each Assumed RSU will be subject to substantially the same terms and conditions as applied to the related Finisar Restricted Stock Unit immediately prior to the Effective Time, except that the number of shares ofII-VI Common Stock subject to such Assumed RSU will be adjusted as described below under “The Merger Agreement — Treatment of Finisar Employee Stock Plans — Restricted Stock Units.”

For more information regarding the treatment of holders of Finisar Restricted Stock Units, see the section entitled “The Merger Agreement — Treatment of Finisar Employee Stock Plans — Restricted Stock Units” beginning on page 144 of this joint proxy statement/prospectus.

Q: I own shares of Finisar Common Stock or am otherwise entitled to elect my form of Merger Consideration. How do I make an election to receive Cash Election Consideration, Stock Election Consideration or Mixed Election Consideration for my shares of Finisar Common Stock or other equity awards?

A: Prior to the closing of the Merger,II-VI will provide a form of election to holders of record of shares of Finisar Common Stock (not including the Dissenting Stockholder Shares or the Excluded Shares, but including holders of Participating RSUs) advising such holders of the procedure for exercising their right to make an election.

Elections to receive Cash Election Consideration (each, a “Cash Election”) and elections to receive Stock Election Consideration (each, a “Stock Election”) are subject to the proration adjustment procedures set forth in the Merger Agreement to ensure that the aggregate Merger Consideration will consist of approximately 60% cash and approximately 40%II-VI Common Stock (with theII-VI Common Stock valued at the closing price as of November 8, 2018).

For more information regarding the election procedures, see the section entitled “The Merger Agreement — Election Procedures” beginning on page 142 of this joint proxy statement/prospectus.

Q: I own shares of Finisar Common Stock or am otherwise entitled to elect my form of Merger Consideration. What is the deadline for submitting my election?

A: To be effective, a form of election must be properly completed, signed and submitted to the Exchange Agent by the Election Deadline (as defined below). Each holder of record of shares of Finisar Common Stock (not including the Dissenting Stockholder Shares or the Excluded Shares, but including holders of Participating

3

RSUs) will have the right, subject to the terms of the Merger Agreement, to submit an election on or prior to 5:00 p.m., New York time, on the date that the parties to the Merger Agreement agree is as near as practicable to two business days prior to the closing date of the Merger (the “Election Deadline”). The parties to the Merger Agreement will cooperate to issue a press release announcing the Election Deadline not more than 15 business days before, and at least five business days prior to, the Election Deadline. Finisar stockholders are urged to promptly submit their properly completed and signed forms of election, together with the necessary transmittal materials, as soon as those materials become available, and not wait until the Election Deadline.

Q: I own shares of Finisar Common Stock or am otherwise entitled to elect my form of Merger Consideration. How can I change or revoke my election?

A: You can change or revoke your election before the Election Deadline by written notice that is sent to and received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed revised form of election.

Q: I own shares of Finisar Common Stock or am otherwise entitled to elect my form of Merger Consideration. What happens if I don’t make an election?

A: A holder of record of shares of Finisar Common Stock (not including the Dissenting Stockholder Shares or the Excluded Shares, but including holders of Participating RSUs) who makes no election or makes an untimely election, or is otherwise deemed not to have submitted an effective form of election, or who has validly revoked the holder’s election but has not properly submitted a new duly completed form of election, will be deemed to have made an election to receive Mixed Election Consideration (a “Mixed Election”).

Q: I own shares of Finisar Common Stock. Can I sell my shares of Finisar Common Stock after I make my election?

A: Yes, but, after an election is validly made, any subsequent transfer of Finisar Common Stock will automatically revoke such election. Following such a revocation, unless a subsequent election is made, the holder of such shares will be deemed to have made a Mixed Election with respect to such shares, regardless of the subsequent holder’s preference.

Q: I own shares of Finisar Common Stock or am otherwise entitled to elect my form of Merger Consideration. If I make a Cash Election or a Stock Election, under what circumstances will the Merger Consideration that I elect to receive be adjusted, and how will any proration adjustment be calculated?

A: If you make a Cash Election, the Merger Consideration that you will receive will be adjusted if the Cash Election Amount exceeds the Available Cash Election Amount, each as defined below. If the Cash Election Amount exceeds the Available Cash Election Amount, then the following Merger Consideration will be paid in respect of each share of Finisar Common Stock with respect to which a Cash Election was made and not revoked or lost in accordance with the terms of the Merger Agreement (each, and as applicable with each Cash Election RSU, a “Cash Electing Share”):

• an amount of cash equal to the quotient of (1) the Available Cash Election Amountdivided by (ii) the number of Cash Electing Shares; and

• a number of shares ofII-VI Common Stock equal to the quotient of (1) the difference of the Available Stock Election Amountless the Stock Election Amountdivided by(2) the number of Cash Electing Shares.

If you make a Stock Election, the Merger Consideration that you will receive will be adjusted if the Available Cash Election Amount exceeds the Cash Election Amount. If the Available Cash Election

4

Amount exceeds the Cash Election Amount, then the following Merger Consideration will be paid in respect of each share of Finisar Common Stock with respect to which a Stock Election was made and not revoked or lost in accordance with the terms of the Merger Agreement (each, and as applicable with each Stock Election RSU, a “Stock Electing Share”):

• an amount of cash equal to the quotient of (1) the difference of the Available Cash Election Amountless the Cash Election Amountdivided by (2) the number of Stock Electing Shares; and

• a number of shares ofII-VI Common Stock equal to the quotient of (1) the Available Stock Election Amountdivided by (2) the number of Stock Electing Shares.

The “Available Cash Election Amount” means (i) the product of $15.60multiplied by the number of total outstanding shares of Finisar Common Stock as of the Effective Time (excluding the Excluded Shares, but including the number of Dissenting Stockholder Shares, Net Option Shares, and Participating RSUs)minus (ii) the aggregate amount of cash to be paid in respect of all shares of Finisar Common Stock with respect to which either a Mixed Election was made and not revoked or with respect to which no election was made (together with the Mixed Election RSUs, the “Mixed Consideration Shares”) (assuming that all Dissenting Stockholder Shares and all Net Option Shares are Mixed Consideration Shares).

The “Available Stock Election Amount” means (i) the product of 0.2218multiplied by the number of total outstanding shares of Finisar Common Stock as of the Effective Time (excluding the Excluded Shares, but including the number of Dissenting Stockholder Shares, Net Option Shares, and Participating RSUs)minus (ii) the aggregate number of shares ofII-VI Common Stock to be paid in respect of all Mixed Consideration Shares (assuming that all Dissenting Stockholder Shares and all Net Option Shares are Mixed Consideration Shares).

The “Cash Election Amount” means the product of (i) the number of Cash Electing Sharesmultiplied by (ii) the Cash Election Consideration (before giving effect to any proration adjustment).

The “Stock Election Amount” means the product of (i) the number of Stock Electing Sharesmultiplied by (ii) the Stock Election Consideration (before giving effect to any proration adjustment).

For more information regarding the proration adjustments, see the section entitled “The Merger Agreement — Merger Consideration” beginning on page 140 of this joint proxy statement/prospectus.

Q: I own shares of Finisar Common Stock. What happens if I am eligible to receive a fraction of a share ofII-VI Common Stock as part of the Merger Consideration?

A: If the aggregate number of shares ofII-VI Common Stock that you are entitled to receive as part of the Merger Consideration includes a fraction of a share ofII-VI Common Stock, you will receive cash in lieu of that fractional share. See the section entitled “The Merger Agreement — Merger Consideration” beginning on page 140 of this joint proxy statement/prospectus.

Q: What equity stake will stockholders of Finisar as of immediately prior to the Merger hold inII-VI immediately following completion of the Merger?

A: Based on the number of shares ofII-VI Common Stock and Finisar Common Stock expected to be outstanding immediately prior to the Effective Time, it is expected that former Finisar stockholders and holders of Finisar equity awards that will receive Merger Consideration will hold, in the aggregate, approximately     % of the outstanding shares ofII-VI Common Stock immediately following the Effective Time.

Q: Who is entitled to vote at theII-VI Special Meeting?

A: All holders of record ofII-VI Common Stock as of the close of business on                 , 2019, the record date for theII-VI Special Meeting (the“II-VI Record Date”), are entitled to receive notice of, and to vote at, the

See the section entitled “Information About the Finisar Special Meeting — Record Date, Outstanding Shares and Quorum” beginning on page 66 of this joint proxy statement/prospectus.

Q: What if I hold shares in bothII-VI and Finisar?

A: If you are both aII-VI shareholder and a Finisar stockholder, you will receive separate packages of proxy materials from each company. A vote as a Finisar stockholder for the approval of the Merger Proposal (or any other proposal to be considered at the Finisar Special Meeting) will not constitute a vote as aII-VI shareholder to approve the Share Issuance Proposal (or any other proposal to be considered at theII-VI Special Meeting), and vice versa. Therefore, please complete, sign and date and return all proxy cards and/or voting instructions that you receive fromII-VI or Finisar, or submit your proxy or voting instructions for each set of voting materials over the Internet or by telephone in order to ensure that all of your shares are voted.

If there is no quorum, theII-VI Special Meeting may be adjourned or postponed to another date if theII-VI Adjournment Proposal is approved, which may subjectII-VI to additional expense and delay or prevent the completion of the Merger.

See the section entitled “Information About theII-VI Special Meeting — Record Date, Outstanding Shares and Quorum” beginning on page 71 of this joint proxy statement/prospectus.

Q: What constitutes a quorum for the Finisar Special Meeting?

A: The presence in person or by proxy at the Finisar Special Meeting of a majority of the shares of Finisar Common Stock issued and outstanding on the Finisar Record Date will constitute a quorum at the Finisar Special Meeting. The presence in person or by proxy of at least                shares of Finisar Common Stock will be required to establish a quorum at the Finisar Special Meeting.

Q: What is the vote required to approve each proposal at theII-VI Special Meeting?

A: Assuming that a quorum is present, approval of the Share Issuance Proposal requires the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast. Accordingly, abstentions will have the same effect as a vote “AGAINST” the Share Issuance Proposal, but shares deemed not in attendance at the meeting, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary will have no effect on the Share Issuance Proposal. This vote will satisfy the vote requirements of Listing Rule 5635(d) of the Nasdaq Stock Market with respect to the Share Issuance Proposal.II-VI cannot complete the Merger unless, among other things, theII-VI shareholders approve the Share Issuance Proposal.

Approval of theII-VI Adjournment Proposal requires the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast,

whether or not a quorum is present. Accordingly, abstentions will have the same effect as a vote “AGAINST” theII-VI Adjournment Proposal, but shares deemed not in attendance at the meeting, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary will have no effect on theII-VI Adjournment Proposal.

See the section entitled “Information About theII-VI Special Meeting — Vote Required” beginning on page 72 of this joint proxy statement/prospectus.

Q: What is the vote required to approve each proposal at the Finisar Special Meeting?

A: Assuming that a quorum is present, approval of the Merger Proposal requires the affirmative vote of holders of a majority of the outstanding shares of Finisar Common Stock. If your shares of Finisar Common Stock are not voted on the Merger Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Merger Proposal, your shares will have the effect of a vote “AGAINST” the Merger Proposal.Finisar cannot complete the Merger, and no Merger Consideration will be paid to Finisar stockholders byII-VI, unless, among other things, the Finisar stockholders approve the Merger Proposal.

Assuming that a quorum is present, approval of the Finisar Adjournment Proposal requires the affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting. If your shares of Finisar Common Stock are not voted on the Finisar Adjournment Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Finisar Adjournment Proposal, your shares will have no effect on the Finisar Adjournment Proposal.

Assuming that a quorum is present, approval of the Compensation Proposal requires the affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting. If your shares of Finisar Common Stock are not voted on the Compensation Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Compensation Proposal, your shares will have no effect on the Compensation Proposal.

See the section entitled “Information About the Finisar Special Meeting — Vote Required” beginning on page 66 of this joint proxy statement/prospectus.

Q: What is the difference between holding shares as a holder of record and as a beneficial owner?

A: If your shares of common stock are registered directly in your name with the transfer agent ofII-VI or Finisar, you are considered the holder of record with respect to those shares. As the holder of record, you have the right to vote or to grant a proxy for your vote directly toII-VI or Finisar, respectively, or to a third party to vote at the applicable special meeting.

If your shares are held by a bank, brokerage firm or other nominee, you are considered the beneficial owner of shares held in “street name,” and your bank, brokerage firm or other nominee is considered the holder of record with respect to those shares. Your bank, brokerage firm or other nominee will send to you, as the beneficial owner, a package describing the procedure for voting your shares. You should follow the instructions provided by them to vote your shares. You are invited to attend the applicable special meeting; however, you may not vote these shares in person at the applicable special meeting unless you obtain a “legal proxy” from your bank, brokerage firm or other nominee that holds your shares, giving you the right to vote the shares at the applicable special meeting.

10

Q: If my shares ofII-VI Common Stock or Finisar Common Stock are held in “street name” by my bank, brokerage firm or other nominee, will my bank, brokerage firm or other nominee automatically vote those shares for me?

A: No. If your shares are held in the name of a bank, brokerage firm or other nominee, you are considered the “beneficial holder” of the shares held for you in what is known as “street name.” You are not the “record holder” of such shares. If this is the case, this joint proxy statement/prospectus has been forwarded to you by your bank, brokerage firm or other nominee. If you hold your shares in “street name,” you must provide instructions to your bank, brokerage firm or other nominee to direct how your shares are to be voted at theII-VI Special Meeting or the Finisar Special Meeting.

Unless your bank, brokerage firm or other nominee has discretionary authority to vote your shares, your bank, brokerage firm or other nominee may not vote your shares without voting instructions from you. In accordance with applicable stock exchange rules, if your shares are held in “street name” through a brokerage firm, your broker has authority to vote on “routine” proposals if you have not provided voting instructions. However, your broker is precluded from exercising voting discretion with respect tonon-routine matters. All of the proposals to be voted on byII-VI shareholders at theII-VI Special Meeting and Finisar stockholders at the Finisar Special Meeting arenon-routine matters. As a result, if your shares are held in “street name” through a brokerage firm and you do not provide voting instructions, your broker will not have discretionary authority to vote your shares at theII-VI Special Meeting or the Finisar Special Meeting, as applicable, and, accordingly,II-VI and Finisar do not expect any brokernon-votes on any of the proposals at the Special Meetings. A brokernon-vote occurs on an item when (i) a broker has discretionary authority to vote on at least one routine proposal at a meeting, but under stock exchange rules is not permitted to vote on othernon-routine proposals without instructions from the beneficial owner of the shares and (ii) that broker exercises its discretionary authority on the routine proposal after the beneficial owner fails to provide such instructions, resulting in brokernon-votes on each of thenon-routine proposals.

If you are a Finisar stockholder and you fail to instruct your bank, brokerage firm or other nominee how to vote your shares, your shares will have the same effect as a vote “AGAINST” the Merger Proposal. Your shares will not be counted, and therefore will have no effect, on any of the other proposals voted on at the Special Meetings if you fail to instruct your bank, brokerage firm or other nominee how to vote your shares.

You should therefore provide your bank, brokerage firm or other nominee with instructions as to how to vote your shares ofII-VI Common Stock or Finisar Common Stock, as applicable.

Please follow the voting instructions provided by your bank, brokerage firm or other nominee so that it may vote your shares on your behalf. Please note that you may not vote shares held in street name by returning a proxy card directly toII-VI or Finisar or by voting in person at your special meeting unless you first obtain a proxy from your bank, brokerage firm or other nominee.

See the sections entitled “Information About theII-VI Special Meeting — Vote Required” beginning on page 72 of this joint proxy statement/prospectus and “Information About the Finisar Special Meeting — Vote Required” beginning on page 66 of this joint proxy statement/prospectus.

Q: How many votes will holders ofII-VI Common Stock have at theII-VI Special Meeting?

A: Holders ofII-VI Common Stock are entitled to one vote for each share ofII-VI Common Stock owned as of theII-VI Record Date. As of theII-VI Record Date, there were                shares ofII-VI Common Stock outstanding.II-VI does not have any outstanding securities that are entitled to vote at theII-VI Special Meeting other than theII-VI Common Stock.

Q: How many votes will holders of Finisar Common Stock have at the Finisar Special Meeting?

A: Holders of Finisar Common Stock are entitled to one vote for each share of Finisar Common Stock owned as of the Finisar Record Date. As of the Finisar Record Date, there were                shares of Finisar Common

11

Stock outstanding. Finisar does not have any outstanding securities that are entitled to vote at the Finisar Special Meeting other than the Finisar Common Stock.

Q: If I submit a proxy, how are my shares voted?

A: Regardless of whether you are aII-VI shareholder or a Finisar stockholder, and regardless of the method you choose to vote, the individuals named on the enclosed proxy card will vote your shares in the way that you indicate at the applicable special meeting. When completing the Internet or telephone processes or the proxy card, you may specify whether your shares should be voted “FOR” or “AGAINST” or to “ABSTAIN” from voting on all, some or none of the specific items of business to come before the applicable special meeting.

If you are aII-VI shareholder and you properly sign your proxy card but do not mark the boxes showing how your shares ofII-VI Common Stock should be voted on a matter, the shares represented by your properly signed proxy will be voted “FOR” the Share Issuance Proposal and “FOR” theII-VI Adjournment Proposal, as applicable.

If you are a Finisar stockholder and you properly sign your proxy card but do not mark the boxes showing how your shares of Finisar Common Stock should be voted on a matter, the shares represented by your properly signed proxy will be voted “FOR” the Merger Proposal, “FOR” the Finisar Adjournment Proposal and “FOR” the Compensation Proposal, as applicable.

If you fail to submit a valid proxy and to attend the applicable special meeting, or if your shares are held through a bank, brokerage firm or other nominee and you do not instruct your bank, brokerage firm or other nominee to vote your shares, your shares will not be voted on any of the matters being considered at the applicable Special Meeting and, if you are a Finisar stockholder, will have the effect of a vote “AGAINST” the Merger Proposal.

See the sections entitled “Information About theII-VI Special Meeting — Voting of Shares, Proxies and Revocation” beginning on page 73 of this joint proxy statement/prospectus and “Information About the Finisar Special Meeting — Voting of Shares, Proxies and Revocation” beginning on page 67 of this joint proxy statement/prospectus.

Q: Can I revoke my proxy or change my voting instructions?

A: Yes. You may revoke your proxy or change your vote, at any time, before your shares are voted at theII-VI Special Meeting or the Finisar Special Meeting, as applicable.

If you are a holder of record ofII-VI Common Stock as of theII-VI Record Date, you can revoke your proxy or change your vote by:

• sending a written notice stating that you revoke your proxy to the Secretary ofII-VI, atII-VI’s offices at 375 Saxonburg Boulevard, Saxonburg, Pennsylvania 16056, Attention: Secretary, that bears a date later than the date of the previously submitted proxy that you want to revoke and is received byII-VI’s Secretary prior to theII-VI Special Meeting;

• submitting a valid, later-dated proxy via mail, over the telephone or through the Internet; or

• attending theII-VI Special Meeting and voting in person, which will automatically cancel any proxy previously given, or revoking your proxy in person, but your attendance alone will not constitute a vote or revoke any proxy previously given.

If you are a holder of record of Finisar Common Stock as of the Finisar Record Date, you can revoke your proxy or change your vote by:

• sending a written notice stating that you revoke your proxy to the Secretary of Finisar, at Finisar’s offices at 1389 Moffett Park Drive, Sunnyvale, California 94089, Attention: Secretary, that bears a date later than the date of the previously submitted proxy that you want to revoke and is received by Finisar’s Secretary prior to the Finisar Special Meeting;

12

• submitting a valid, later-dated proxy via mail, over the telephone or through the Internet; or

• attending the Finisar Special Meeting and voting in person, which will automatically cancel any proxy previously given, or revoking your proxy in person, but your attendance alone will not constitute a vote or revoke any proxy previously given.

In either case, if you hold your shares in street name, you must contact your nominee or intermediary to change your vote or obtain a legal proxy to vote your shares if you wish to cast your vote in person at theII-VI Special Meeting or the Finisar Special Meeting.

See the sections entitled “Information About theII-VI Special Meeting — Voting of Shares, Proxies and Revocation” beginning on page 73 of this joint proxy statement/prospectus and “Information About the Finisar Special Meeting — Voting of Shares, Proxies and Revocation” beginning on page 67 of this joint proxy statement/prospectus.

Q: What happens if I transfer my shares ofII-VI Common Stock before theII-VI Special Meeting?

A: TheII-VI Record Date is earlier than the date of theII-VI Special Meeting and the date that the Merger is expected to be completed. If you transfer your shares ofII-VI Common Stock after theII-VI Record Date, but before theII-VI Special Meeting, you will retain your right to vote at theII-VI Special Meeting.

Q: What happens if I transfer my shares of Finisar Common Stock before the Finisar Special Meeting?

A: The Finisar Record Date is earlier than the date of the Finisar Special Meeting and the date that the Merger is expected to be completed. If you transfer your shares of Finisar Common Stock after the Finisar Record Date, but before the Finisar Special Meeting, you will retain your right to vote at the Finisar Special Meeting. However, you will have transferred the right to receive the Merger Consideration in the Merger. In order to receive the Merger Consideration, you must hold your shares of Finisar Common Stock through the Effective Time. In addition, after an election is validly made with respect to Merger Consideration, any subsequent transfer of Finisar Common Stock will automatically revoke such election. Following such revocation, unless a subsequent election is made, the holder of such shares of Finisar Common Stock will be deemed to have made a Mixed Election with respect to such shares.

Q: What do I do if I receive more than one set of voting materials?

A: You may receive more than one set of voting materials, including multiple copies of this joint proxy statement/prospectus and multiple proxy cards or voting instruction forms. This can occur if you hold shares of bothII-VI Common Stock and Finisar Common Stock, if your shares ofII-VI Common Stock or Finisar Common Stock are held in more than one brokerage account, if you hold your shares ofII-VI Common Stock or Finisar Common Stock directly as a holder of record and also in street name, or otherwise through another holder of record, and in certain other circumstances. If you receive more than one set of voting materials, please vote or return each set separately in order to ensure that all of your shares are voted.

Q: What will happen if all of the proposals to be considered at theII-VI Special Meeting and the Finisar Special Meeting are not approved?

A: As a condition to completion of the Merger,II-VI shareholders must approve the Share Issuance Proposal at theII-VI Special Meeting, and Finisar stockholders must approve the Merger Proposal at the Finisar Special Meeting. Completion of the Merger is not conditioned or dependent upon the approval of theII-VI Adjournment Proposal at theII-VI Special Meeting or the approval of the Finisar Adjournment Proposal or the Compensation Proposal at the Finisar Special Meeting.

Q: Am I entitled to exercise appraisal rights?

A: If you are a holder ofII-VI Common Stock, you are not entitled to appraisal rights in connection with the Merger under Pennsylvania law.

13

Under Delaware law, record holders of Finisar Common Stock who choose the Stock Election Consideration for their shares of Finisar Common Stock, but receive a mix of cash andII-VI Common Stock for such shares through the proration adjustment mechanism in connection with an oversubscription of the Stock Election Consideration, will be entitled to appraisal rights for such shares if such stockholders have otherwise complied with the requirements of Section 262 of the DGCL.Appraisal rights will not be available to Finisar stockholders who fail to make an election and receive the Mixed Election Consideration or to Finisar stockholders who choose the Cash Election Consideration or the Mixed Election Consideration.

In addition, a stockholder who desires to exercise appraisal rights must neither vote in favor of the Merger Proposal nor consent thereto in writing, must continuously hold his, her or its shares of Finisar Common Stock through the effective date of the Merger, must deliver to Finisar a written demand for appraisal prior to the date of the Finisar Special Meeting and must otherwise comply with the procedures set forth in Section 262 of the DGCL.

If the Merger is completed, subject to the provisions of Section 262 of the DGCL, Finisar stockholders who are entitled to, and properly perfect, their appraisal rights will obtain payment in cash of the fair value of their shares of Finisar Common Stock as determined by the Delaware Court of Chancery, instead of receiving the Merger Consideration for their shares. The “fair value” of shares of Finisar Common Stock as determined by the Delaware Court of Chancery could be greater than, the same as, or less than the value of the Merger Consideration that Finisar stockholders would otherwise be entitled to receive under the terms of the Merger Agreement.

However, notwithstanding a Finisar stockholder’s compliance with the DGCL in perfecting appraisal rights, under Section 262 of the DGCL, assuming Finisar Common Stock remains listed on a national securities exchange immediately prior to the Effective Time, the Delaware Court of Chancery will dismiss any appraisal proceedings as to all Finisar stockholders who are otherwise entitled to appraisal rights unless (i) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of Finisar Common Stock, or (ii) the value of the consideration provided in the Merger for such total number of shares entitled to appraisal exceeds $1 million. To exercise appraisal rights, Finisar stockholders must comply with the procedures prescribed by Section 262 of the DGCL. These procedures are summarized in the section entitled “Appraisal Rights” beginning on page 215 of this joint proxy statement/prospectus. In addition, a copy of the full text of Section 262 of the DGCL is included asAnnex D to this joint proxy statement/prospectus. Failure to comply with these provisions may result in a loss of the right of appraisal.

Q: What is the expected timing of the completion of the Merger?

A: Subject to the satisfaction or waiver of each of the closing conditions described under the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 160 of this joint proxy statement/prospectus, including the approval of the Share Issuance Proposal byII-VI shareholders at theII-VI Special Meeting and the approval of the Merger Proposal by Finisar stockholders at the Finisar Special Meeting,II-VI and Finisar expect that the Merger will be completed approximately in the middle of 2019. However, it is possible that factors outside the control of both companies could result in the Merger being completed at a different time or not at all.

As described in the sections entitled “The Merger Agreement — Conditions to Completion of the Merger” and “The Merger — Regulatory Approvals” beginning on pages 160 and 129, respectively, of this joint proxy statement/prospectus, completion of the Merger is conditioned on, among other things, (i) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and (ii) receipt of all other consents under certain specified federal, state, local or foreign antitrust, competition, premerger notification or trade regulation laws, regulations or orders.

14

Q: Are there any important risks related to the Merger orII-VI’s or Finisar’s businesses of which I should be aware?

A: Yes, there are important risks related to the Merger and each ofII-VI’s and Finisar’s businesses. Before making any decision on how to vote,II-VI and Finisar urge you to read carefully and in its entirety the section entitled “Risk Factors” beginning on page 48 of this joint proxy statement/prospectus. You also should read and carefully consider the risk factors relating toII-VI and Finisar contained in the documents that are incorporated by reference into this joint proxy statement/prospectus, includingII-VI’s Annual Report on Form10-K for its fiscal year ended June 30, 2018, as updated from time to time inII-VI’s subsequent filings with the SEC, and Finisar’s Annual Report on Form10-K for its fiscal year ended April 29, 2018, as updated from time to time in Finisar’s subsequent filings with the SEC.

Q: Do Finisar directors and officers have interests that may differ from those of other Finisar stockholders?

A: Yes. In considering the recommendation of the Finisar Board that Finisar stockholders vote “FOR” the Merger Proposal, Finisar stockholders should be aware and take into account the fact that certain Finisar directors and executive officers have interests in the Merger that may be different from, or in addition to, the interests of Finisar stockholders generally. The Finisar Board was aware of and considered these interests, among other matters, in evaluating the terms and structure, and overseeing the negotiation of, the Merger, in approving the Merger Agreement and in recommending that Finisar stockholders vote “FOR” the adoption of the Merger Proposal. See the section entitled “Finisar Proposal No. 3 —Non-Binding, Advisory Vote on Merger-Related Compensation for Finisar’s Named Executive Officers” beginning on page 189 of this joint proxy statement/prospectus and “Interests of Finisar’s Directors and Executive Officers in the Merger” beginning on page 166 of this joint proxy statement/prospectus.

Q: What are the material U.S. federal income tax consequences of the Merger to U.S. holders ofII-VI Common Stock and Finisar Common Stock?

A: U.S. holders ofII-VI Common Stock will not recognize any income, gain or loss as a result of the Merger due solely to their ownership ofII-VI Common Stock. U.S. holders ofII-VI Common Stock that also hold Finisar Common Stock will be subject to the tax consequences described below with respect to their ownership of Finisar Common Stock.

The exchange of Finisar Common Stock for cash,II-VI Common Stock or both in the Merger generally will be a taxable transaction for U.S. holders of Finisar Common Stock for U.S. federal income tax purposes and may also be taxable under state, local or other tax laws. You should read the section entitled “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 132 of this joint proxy statement/prospectus for more information.

Tax matters can be complicated and the tax consequences of the Merger to you will depend on your particular circumstances. You are urged to consult your tax advisor regarding the U.S. federal income tax consequences of the Merger to you in your particular circumstances, as well as tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Q: What are the conditions to completion of the transactions?

A: In addition to the approval of the Share Issuance Proposal byII-VI shareholders and the approval of the Merger Proposal by Finisar stockholders as described above, completion of the Merger is subject to the satisfaction or, to the extent permissible under applicable law, waiver of a number of other conditions, including, among other things, the receipt of required regulatory approvals, the accuracy ofII-VI’s and Finisar’s respective representations and warranties under the Merger Agreement (subject to certain materiality exceptions) andII-VI’s and Finisar’s performance of their respective obligations under the

15

Merger Agreement. For a more complete summary of the conditions that must be satisfied or waived prior to completion of the Merger, see the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 160 of this joint proxy statement/prospectus.

Q: What happens if the Merger is not completed?

A: If the Share Issuance Proposal is not approved byII-VI shareholders or the Merger Proposal is not approved by Finisar stockholders, or any of the other conditions to the Merger are not satisfied or waived for any other reason, Finisar stockholders will not receive any Merger Consideration for their shares of Finisar Common Stock. Instead, Finisar will remain an independent public company, Finisar Common Stock will continue to be listed and traded on the Nasdaq Global Select Market and registered under the Exchange Act, and Finisar will continue to file periodic reports with the SEC. Under specified circumstances,II-VI or Finisar may be required to pay the other party a termination fee of $105.2 million. See the section entitled “The Merger Agreement — Fees and Expenses and Termination Fees” beginning on page 163 of this joint proxy statement/prospectus.

Q: How will Finisar stockholders receive the Merger Consideration to which they are entitled?

A: If you hold physical share certificates of Finisar Common Stock, you will be sent a letter of transmittal promptly after the Effective Time describing how you may exchange your shares of Finisar Common Stock for the Merger Consideration to which you are entitled, and the Exchange Agent will forward to you the applicable Merger Consideration to which you are entitled after receiving the proper documentation from you. If you hold your shares of Finisar Common Stock in uncertificated book-entry form, you are not required to take any specific actions to exchange your shares of Finisar Common Stock, and after the completion of the Merger, such shares will be automatically exchanged for the Merger Consideration. For more information on the documentation you are required to deliver to the Exchange Agent, see the sections entitled “The Merger Agreement — Election Procedures” beginning on page 142 of this joint proxy statement/prospectus and “The Merger Agreement — Exchange Procedures” beginning on page 143 of this joint proxy statement/prospectus.

A: No. The receipt of any financing byII-VI is not a condition to completion of the Merger and, except in certain limited circumstances in whichII-VI or Finisar may be permitted to terminate the Merger Agreement (as more fully described in “The Merger Agreement — Termination of the Merger Agreement”),II-VI will be required to complete the Merger (assuming that all of the conditions to its obligations to complete the Merger under the Merger Agreement are satisfied or waived) whether or not financing is available on acceptable terms or at all.

On November 8, 2018, in connection with its entry into the Merger Agreement,II-VI entered into a commitment letter (together with a related fee letter) with Bank of America, N.A. (“Bank of America”), which was subsequently amended and restated on December 7, 2018 and on December 14, 2018 (together with one or more related fee letters, the “Commitment Letter”).

Ownership ofII-VI Common Stock After the Merger (See page 76)

Based on the number of shares of Finisar Common Stock outstanding as of                 , 2019, and the treatment of shares of Finisar Common Stock, Finisar Stock Options and Finisar Restricted Stock Units in the Merger, and assuming no conversions of the Finisar Convertible Notes,II-VI expects to issue approximately         million shares ofII-VI Common Stock to holders of Finisar Common Stock and Finisar equity awards upon completion of the Merger. The actual number of shares ofII-VI Common Stock to be issued upon completion of the Merger will be determined at the completion of the Merger based on, among other things, the number of shares of Finisar Common Stock outstanding and the market price ofII-VI Common Stock at that time. Based on the number of shares of Finisar Common Stock outstanding as of                 , 2019, and the number of shares ofII-VI Common Stock outstanding as of                 , 2019, it is expected that, immediately after completion of the Merger, former holders of Finisar Common Stock and Finisar equity awards will own approximately      % of the outstanding shares ofII-VI Common Stock.

Governance Matters Following Completion of the Merger (See page 139)

After completion of the Merger, the directors of Merger Sub and the officers of Finisar immediately prior to completion of the Merger will be the directors and officers, respectively, of the Surviving Corporation.

At the Effective Time, theII-VI Board will appoint three members of the Finisar Board as of November 8, 2018 to serve on theII-VI Board (the “Finisar Designees”). Each Finisar Designee will be mutually agreed upon byII-VI and Finisar, acting in good faith. In addition, the Corporate Governance and Nominating Committee of theII-VI Board previously will have reasonably approved the appointment of the Finisar Designees to theII-VI Board, which also will have previously recommended the appointment of the Finisar Designees to the fullII-VI Board. The total number of directors on theII-VI Board at the Effective Time will be no more than 11 persons. As of the date hereof, the identity of the Finisar Designees has not been determined byII-VI and Finisar.

Also at the Effective Time, theII-VI Board will have four committees, consisting of an Audit Committee, a Compensation Committee, a Subsidiary Committee and a Corporate Governance and Nominating Committee. Each such committee will include at least one Finisar Designee.

In considering the recommendation of the Finisar Board that Finisar stockholders vote to adopt the Merger Agreement, Finisar stockholders should be aware that, aside from their interests as Finisar stockholders, Finisar’s directors and executive officers have interests in the Merger that may be different from, or in addition to, those of Finisar stockholders generally. These interests include, among others, potential severance benefits and other payments, the treatment of outstanding equity awards pursuant to the Merger Agreement, and certain indemnification rights of Finisar directors and officers under the Merger Agreement. Members of the Finisar Board were aware of and considered these interests, among other matters, at the time of evaluating and negotiating the Merger Agreement and the Merger, approving the Merger Agreement and the Merger, and recommending to Finisar stockholders that the Merger Agreement be adopted.

For more information, see the sections entitled “The Merger — Background of the Merger” and “The Merger — Finisar’s Reasons for the Merger; Recommendations of the Finisar Board” beginning on pages 77 and 96, respectively, of this joint proxy statement/prospectus. These interests are described in more detail below section entitled “Interests of Finisar’s Directors and Executive Officers in the Merger” beginning on page 166 of this joint proxy statement/prospectus, and certain of them are quantified in the narrative of the section entitled “Finisar Proposal No. 3 —Non-Binding, Advisory Vote on Merger-Related Compensation for Finisar’s Named Executive Officers —  Golden Parachute Compensation” beginning on page 189 of this this joint proxy statement/prospectus.

Listing ofII-VI Common Stock; Delisting and Deregistration of Finisar Common Stock (See page 130)

II-VI will file a notification of listing of additional shares (or such other form as may be required) with the Nasdaq Global Select Market, whereII-VI Common Stock currently is traded, with respect to the shares ofII-VI Common Stock to be issued in the Merger. If the Merger is completed, Finisar Common Stock will be delisted from the Nasdaq Global Select Market and will be deregistered under the Exchange Act. See the section entitled “The Merger — Listing ofII-VI Common Stock; Delisting and Deregistration of Finisar Common Stock” beginning on page 130 of this joint proxy statement/prospectus.

Comparison of Shareholder Rights (See page 196)

Finisar stockholders will have different rights once they becomeII-VI shareholders due to differences between the organizational documents of, and the applicable state laws governing, Finisar andII-VI. See “Comparison of Shareholders’ Rights” beginning on page 196 of this joint proxy statement/prospectus.

Appraisal Rights Available to Finisar Stockholders (See page 215)

Pursuant to Section 262 of the DGCL, a Finisar stockholder at the Finisar Record Date who chooses the Stock Election Consideration for his, her or its shares of Finisar Common Stock, but receives a mix ofII-VI Common Stock and cash for such shares through the proration adjustment mechanism in connection with an oversubscription of the Stock Election Consideration, will be entitled to appraisal rights for such shares if such stockholder otherwise complies with the requirements of Section 262 of the DGCL. Appraisal rights will not be available to Finisar stockholders who fail to make an election and receive the Mixed Election Consideration or to Finisar stockholders who choose the Cash Election Consideration or the Mixed Election Consideration.

Finisar stockholders who wish to exercise the right to seek an appraisal of their shares must not vote in favor of the Merger Proposal nor consent thereto in writing, must continuously hold their shares of Finisar Common

28

Stock through the effective date of the Merger, must deliver to Finisar a written demand for appraisal prior to the date of the Finisar Special Meeting and must otherwise comply with the applicable requirements of Section 262 of the DGCL. The appraisal remedy offers eligible stockholders the right to seek appraisal of the fair value of their shares of Finisar Common Stock, as determined by the Delaware Court of Chancery, if the Merger is completed. The “fair value” of shares of Finisar Common Stock as determined by the Delaware Court of Chancery could be greater than, the same as, or less than the value of the Merger Consideration that Finisar stockholders would otherwise be entitled to receive under the terms of the Merger Agreement.

The right to seek appraisal will be lost if a Finisar stockholder votes “FOR” the Merger Proposal. However, abstaining or voting against the Merger Proposal is not in itself sufficient to perfect appraisal rights because additional actions must also be taken to perfect such rights.

Finisar stockholders who wish to exercise the right to seek an appraisal of their shares must so advise Finisar by submitting a written demand for appraisal prior to the taking of the vote on the Merger Proposal at the Finisar Special Meeting, and must otherwise follow the procedures prescribed by Section 262 of the DGCL. A person having a beneficial interest in shares of Finisar Common Stock held of record in the name of another person, such as a nominee or intermediary, must act promptly to cause the record holder to follow the steps required by Section 262 of the DGCL and in a timely manner to perfect appraisal rights. In view of the complexity of Section 262 of the DGCL, Finisar stockholders that may wish to pursue appraisal rights are urged to consult their legal and financial advisors.

However, notwithstanding a Finisar stockholder’s compliance with the DGCL in perfecting appraisal rights, under Section 262 of the DGCL, assuming Finisar Common Stock remains listed on a national securities exchange immediately prior to the Effective Time, the Delaware Court of Chancery will dismiss any appraisal proceedings as to all stockholders who are otherwise entitled to appraisal rights unless (i) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of Finisar Common Stock, or (ii) the value of the consideration provided in the Merger for the total number of shares of Finisar Common Stock entitled to appraisal exceeds $1 million. These procedures are summarized in the section entitled “Appraisal Rights” beginning on page 215 of this joint proxy statement/prospectus. In addition, a copy of the full text of Section 262 of the DGCL is included asAnnex D to this joint proxy statement/prospectus.

Conditions to Completion of the Merger (See page 160)

As more fully described in this joint proxy statement/prospectus and in the Merger Agreement, the obligation of each ofII-VI and Merger Sub, on the one hand, and Finisar, on the other hand, to complete the Merger is subject to the satisfaction (or, to the extent permissible under applicable law, waiver) of a number of conditions, including the following:

• the absence of a material adverse effect on the other party (see “The Merger Agreement — Representations and Warranties” beginning on page 145 of this joint proxy statement/prospectus for the definition of material adverse effect).

In addition to the conditions to all parties’ obligations, the obligation of Finisar to complete the Merger is subject toII-VI, Finisar and the Trustee entering into supplemental indentures to the 2033 Notes Indenture and the 2036 Notes Indenture, as more fully described in the section entitled “The Merger — Treatment of Finisar Convertible Notes” beginning on page 136 of this joint proxy statement/prospectus.

II-VI and Finisar cannot be certain when, or if, the conditions to the Merger will be satisfied or waived, or that the Merger will be completed.

Required Regulatory Approvals (See page 129)

Completion of the Merger is conditioned upon (i) the expiration or early termination of the waiting period relating to the Merger under the HSR Act and (ii) obtaining all consents, approvals, licenses, permits, certificates, orders or authorizations of any governmental authority under certain specified federal, state, local or foreign antitrust, competition, premerger notification or trade regulation laws, regulations or orders.

Under the HSR Act, certain transactions, including the Merger, may not be completed unless certain waiting period requirements have expired or been terminated. The HSR Act provides that each party must file apre-merger notification with the Federal Trade Commission (the “FTC”) and the Antitrust Division of the U.S. Department of Justice (the “DOJ”). A transaction notifiable under the HSR Act may not be completed until the expiration of a30-calendar-day waiting period following the parties’ filings of their respective HSR Act notification forms or the early termination of that waiting period.

Other specified federal, state, local or foreign antitrust, competition, premerger notification or trade regulation laws, regulations or orders pursuant to which completion of the Merger is conditioned include the following:

• Anti-monopoly Law of the People’s Republic of China of 2008 (as amended);

• Act against Restraints of Competition of 1958(Gesetz gegen Wettbewerbsbeschränkungen)(as amended);

• Federal Economic Competition Law of 2014(Ley Federal de Competencia Económica) and its regulations(Disposiciones Regulatorias de la Ley Federal de Competencia Económica); and

• Competition Law no. 21/1996(Lege nr. 21 din 10 aprilie 1996 a Concurenţei—Republicare) (as amended) and Regulation on Economic Concentrations approved by Romanian Competition Council Order No. 431/2017(Ordinul nr. 431/2017 pentru punerea în aplicare a Regulamentului privind concentrările economice).

NeitherII-VI nor Finisar is aware of any material governmental approvals or actions that are required for completion of the Merger other than those described above. It is presently contemplated that if any such additional material governmental approvals or actions are required, those approvals or actions will be sought.

30

II-VI and Finisar have agreed to use their respective reasonable best efforts to cause the closing of the Merger to occur, which “reasonable best efforts” ofII-VI include promptly opposing any motion or action for an injunction against the Merger or any portion thereof, including any legislative, administrative or judicial action, and taking any and all steps necessary to have vacated, lifted, reversed, overturned, avoided, eliminated or removed any decree, judgment, injunction or other order that restricts, prevents or prohibits the consummation of the Merger or any other transactions contemplated by the Merger Agreement under the HSR Act, or other federal, state, local or foreign antitrust, competition, premerger notification or trade regulation laws, regulations or orders; provided that such efforts shall not requireII-VI, its subsidiaries or its affiliates to make certain divestitures or agree to make certain divestitures or other limitations or take any other action that, individually or in the aggregate, would have a material adverse effect onII-VI, Finisar and their respective subsidiaries, taken as a whole, after the consummation of the transactions contemplated by the Merger Agreement.

For more information, see the section entitled “The Merger — Regulatory Approvals” beginning on page 129 of this joint proxy statement/prospectus.

Expected Completion Date for the Merger (See page 139)

The parties expect that the Merger will be completed approximately in the middle of 2019. However, it is possible that factors outside the control of both companies could result in the Merger being completed at a different time or not at all.

Material U.S. Federal Income Tax Consequences of the Merger (See page 132)

The exchange of Finisar Common Stock for cash,II-VI Common Stock or both in the Merger generally will be a taxable transaction for U.S. federal income tax purposes and also may be taxable under state and local and other tax laws. You should read the section entitled “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 132 of this joint proxy statement/prospectus. Tax matters can be complicated and the tax consequences of the Merger to you will depend on your particular circumstances. You are urged to consult your tax advisor regarding the U.S. federal income tax consequences of the Merger to you in your particular circumstances, as well as tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Accounting Treatment of the Merger (See page 135)

In accordance with United States generally accepted accounting principles (“GAAP”),II-VI will account for the Merger using the acquisition method of accounting, withII-VI being considered the acquirer of Finisar for accounting purposes. This means thatII-VI will allocate the purchase price to the fair value of Finisar tangible and intangible assets and liabilities at the acquisition date, with the excess purchase price, if any, being recorded as goodwill. Under the acquisition method of accounting, goodwill is not amortized but is tested for impairment at least annually. The operating results of Finisar will be reported as part of the combined company beginning on the closing date of the Merger. The final valuation of the tangible and identifiable intangible assets acquired and liabilities assumed has not yet been completed and is not required to be completed under applicable guidance until 12 months after completion of the Merger. The finalization of the valuation could result in significantly different amortization expenses and balance sheet classifications than those presented inII-VI’s unaudited pro forma condensed combined financial information included in this joint proxy statement/prospectus.

For more information, see the section entitled “The Merger — Accounting Treatment of the Merger” beginning on page 135 of this joint proxy statement/prospectus.

31

Non-Solicitation Obligations (See page 151)

As more fully described in this joint proxy statement/prospectus and in the Merger Agreement, and subject to the exceptions described below and in the Merger Agreement, Finisar has agreed not to, among other things, (i) solicit, initiate or knowingly encourage or knowingly facilitate any inquiries or offers that constitute or would reasonably be expected to lead to takeover proposal from a third party, (ii) enter into, continue or otherwise participate in any negotiations or discussions with any third party regarding any takeover proposal or that would reasonably be expected to lead to a takeover proposal, (iii) furnish any nonpublic information to a third person in connection with any takeover proposal or any inquiry, indication of interest, proposal or offer that would reasonably be expected to lead to a takeover proposal, (iv) release any provision of any confidentiality or similar provision of any agreement to which Finisar is a party, (v) approve any transaction under, or any person becoming an “interested stockholder” under, Section 203 of the DGCL, or (vi) enter into a letter of intent, agreement in principle, merger agreement or other similar agreement contemplating or otherwise relating to a takeover proposal. Finisar will also be liable for a breach of its representatives of thenon-solicitation provisions in the Merger Agreement

However, at any time prior to the approval of the Merger Proposal by Finisar stockholders, subject to the terms and conditions described in the Merger Agreement, Finisar may, in response to an unsolicited, bona fide, written takeover proposal that the Finisar Board concludes in good faith, after consultation with its advisors, is, or is reasonably likely to lead to, a superior proposal, (i) furnish any information (including nonpublic information) and access relating to Finisar or any of its subsidiaries to the person making the takeover proposal and (ii) enter into, engage and participate in discussions or negotiations with such person and its representatives (subject to promptly notifyingII-VI in writing of the identity of the person making the takeover proposal, the material terms thereof and a copy of any written proposal or definitive agreement relating to the takeover proposal); provided, in each case, that such takeover proposal did not result from a breach of thenon-solicitation provisions in the Merger Agreement, Finisar enters into a confidentiality agreement with such third party that is no less favorable than the confidentiality agreement entered into withII-VI, except that such confidentiality agreement may contain a less restrictive or no standstill or similar restriction, and Finisar provides toII-VI any nonpublic information made available to such third party that was not previously made available toII-VI.

For more information, see the section entitled “The Merger Agreement — No Solicitation of Alternative Proposals” beginning on page 151 of this joint proxy statement/prospectus.

• if, prior to the date theII-VI shareholders adopt the Share Issuance Proposal, theII-VI Board withdraws, amends or modifies (or publicly proposes to withdraw, amend or modify) in a manner adverse to Finisar its recommendation thatII-VI shareholders approve the Share Issuance Proposal; provided that Finisar terminates within the earlier of (i) 15 business days after obtaining actual knowledge of such actions and (ii) the day immediately preceding theII-VI Special Meeting; or

• at any time prior to the date the Finisar stockholders adopt the Merger Proposal, in order to enter into a written definitive agreement with respect to a superior proposal (which definitive agreement

For more information, see the section entitled “The Merger Agreement — Fees and Expenses and Termination Fees” beginning on page 163 of this joint proxy statement/prospectus.

Specific Performance; Remedies (See page 165)

Under the Merger Agreement, each ofII-VI and Finisar is entitled to an injunction or injunctions to prevent breaches of the Merger Agreement and to specifically enforce the terms and provisions of the Merger Agreement. See the section entitled “The Merger Agreement — Specific Performance” beginning on page 165 of this joint proxy statement/prospectus.

Description of Debt Financing (See page 135)

On November 8, 2018, in connection with its entry into the Merger Agreement,II-VI entered into the Commitment Letter, which was subsequently amended and restated on December 7, 2018 and on December 14, 2018. Subject to the terms and conditions set forth in the Commitment Letter, the Lending Parties have severally committed to provide 100% of up to $2.425 billion in aggregate principal amount of theII-VI Senior Credit Facilities, comprised of (i) a “term a” loan facility of up to $1.0 billion, a portion of which will be available after the closing of the Merger on a delayed draw basis, (ii) a “term b” loan facility of up to $975.0 million and (iii) a revolving credit facility of up to $450.0 million.II-VI currently intends to pay the cash portion of the aggregate Merger Consideration and pay related fees and expenses in connection with the Merger using the proceeds of draws under theII-VI Senior Credit Facilities and cash and short-term investments ofII-VI and Finisar.II-VI currently does not intend to draw on the revolving credit facility in order to fund the cash portion of the aggregate Merger Consideration.

The commitments of the Lead Arrangers with respect to theII-VI Senior Credit Facilities will automatically terminate at 11:59 p.m., New York City time, on the first to occur of (i) November 8, 2019 (unless the Merger occurs on or prior thereto), (ii) the date of closing of the Merger without the use of proceeds from theII-VI Senior Credit Facilities or (iii) the date on whichII-VI delivers written notice to terminate its obligations under the Merger Agreement pursuant to the terms thereof or the date that the Merger Agreement is terminated.

The documentation governing theII-VI Senior Credit Facilities has not been finalized and, accordingly, the actual terms of theII-VI Senior Credit Facilities may differ from those described herein or in the Commitment Letter as a result of the syndication process. Although the debt financing described in this joint proxy statement/prospectus is not subject to a due diligence or “market out,” such financing may not be considered assured. The obligation of the Lead Arrangers to provide the debt financing under the Commitment Letter is subject to a number of conditions. There is a risk that these conditions will not be satisfied and theII-VI Senior Credit Facilities may not be funded when required or at all. As of the date of this joint proxy statement/prospectus, no alternative financing arrangements have been made in the event theII-VI Senior Credit Facilities are not available, and any such alternative financing arrangements may not be available on acceptable terms, or at all, if theII-VI Senior Credit Facilities are not consummated.

See the section entitled “The Merger — Description of Debt Financing” beginning on page 135 of this joint proxy statement/prospectus.

Treatment of Finisar Convertible Notes (See page 136)

As of the date of this joint proxy statement/prospectus, Finisar has outstanding approximately $1.1 million aggregate principal amount of 2033 Notes and $575.0 million aggregate principal amount of 2036 Notes.

At the consummation of the Merger and pursuant to the Indentures,II-VI, the Surviving Corporation and the Trustee will enter into supplemental indentures to the Indentures. The respective supplemental indentures will comply with the applicable terms of the Indentures and will, among other things, provide that (y) at and after the Effective Time, the right to convert each $1,000 principal amount of the applicable Finisar Convertible Notes will be changed into a right to convert such principal amount of the applicable Finisar Convertible Notes into the weighted average of the types and amounts of consideration received by holders of Finisar Common Stock that affirmatively make an election to receive Cash Election Consideration, Stock Election Consideration or Mixed Election Consideration that a holder of a number of shares of Finisar Common Stock equal to the applicable conversion rate immediately prior to the consummation of the Merger would have owned or been entitled to receive in connection with the Merger (the “Reference Property”) and(z) II-VI fully and unconditionally guarantees, on a senior unsecured basis, the Finisar Convertible Notes.

Pursuant to the terms of the Indentures, consummation of the Merger will constitute a “Fundamental Change” and a “Make Whole Fundamental Change.” As a result, holders of the Finisar Convertible Notes will be permitted to choose, pursuant, and subject, to the terms and conditions of the Indentures (i) to convert their Finisar Convertible Notes, (ii) to require Finisar to repurchase their Finisar Convertible Notes for a price equal to 100% of their principal amount, together with accrued and unpaid interest to, but excluding, the repurchase date, or (iii) to continue holding their Finisar Convertible Notes until maturity or until they are otherwise redeemed, repurchased, or converted pursuant to the terms of the applicable Indenture. NeitherII-VI, Merger Sub, Finisar nor any of their respective affiliates or representatives have made, or intend to make, any recommendation to any holder of Finisar Convertible Notes regarding this election.

Pursuant to the terms of the Indentures, Finisar, as the Surviving Corporation, will continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of the Finisar Convertible Notes, and any amount payable in cash upon conversion of the Finisar Convertible Notes will continue to be payable in cash, although any shares of Finisar Common Stock that Finisar would have been required to deliver upon conversion of the Finisar Convertible Notes instead will be deliverable in the amount and type of Reference Property that a holder of that number of shares of Finisar Common Stock would have received in connection with the Merger. See the section entitled “The Merger — Treatment of Finisar Convertible Notes” beginning on page 136 of this joint proxy statement/prospectus.

Litigation Relating to the Merger (See page 137)

As of January 17, 2019, six lawsuits have been filed by alleged Finisar stockholders challenging the Merger. The first complaint, a putative class action complaint, was filed by Herbert Hein in the Superior Court of California, County of Santa Clara, and is captionedHein v. Finisar Corporation, et al., 19CV340510. The second complaint, a putative class action complaint, was filed by Pete Tenvold in the United States District Court for the District of Delaware and is captionedTenvold v. Finisar Corporation, et al., 1:19-cv-00050. The third complaint, a putative class action complaint, was filed by Melvyn Klein in the United States District Court for the Northern District of California and is captionedKlein v. Finisar Corporation, et al., 3:19-cv-00155. The fourth complaint, a putative class action complaint, was filed by Earl Wheby, Jr. in the United States District Court for the District of Delaware and is captionedWheby v. Finisar Corporation, et al., 1:19-cv-00064. The fifth complaint was filed by Pankaj Sharma individually in the United States District Court for the Northern District of California and is captionedSharma v. Finisar Corporation, et al.,3:19-cv-00220. The sixth complaint, a putative class action complaint, was filed by William Davis in the United States District Court for the Northern District of California and is captionedDavis v. Finisar Corporation, et al., 3:19-cv-00271.

36

The complaints name as defendants Finisar and each member of the Finisar Board. In addition, theHein,Tenvold, andKlein complaints name II-VI and Merger Sub as defendants. TheHein,Tenvold,Klein,Wheby, andDavis complaints seek relief on behalf of a putative class defined as all similarly situated Finisar stockholders.

The Heincomplaint alleges that the Finisar Board breached its fiduciary duties to Finisar stockholders by purportedly engaging in an insufficient sales process, obtaining inadequate merger consideration, and filing a materially misleading preliminary proxy statement that does not include, among other things, material information regarding the sales process, financial projections for both Finisar and II-VI, and financial analyses conducted by their financial advisors. TheHein complaint further asserts that II-VI knowingly aided and abetted the Finisar Board in breaching their fiduciary duties to Finisar stockholders by entering into the proposed transaction. TheHeincomplaint seeks preliminary and permanent injunction of the proposed transaction unless the information requested by the plaintiff is disclosed, rescission and unspecified damages if the Merger is consummated, and attorneys’ fees and expert fees and costs.

TheTenvold, Klein, Wheby, Sharma, andDaviscomplaints purport to state claims for violations of Section 14(a) and 20(a) of the Exchange Act and Rule 14a-9 and, in the case of theDavis complaint, Regulation G promulgated thereunder. The plaintiffs in these actions generally allege that the preliminary proxy statement omits material information with respect to the proposed transaction which renders the preliminary proxy statement false and misleading. The plaintiffs in these actions seek an order enjoining the defendants from filing a definitive proxy statement with the SEC or otherwise disseminating a definitive proxy statement to Finisar stockholders or proceeding with closing the Merger unless and until the preliminary proxy statement is cured. In the event the Merger is consummated prior to entry of final judgment, theTenvold, Klein, Wheby, andSharmacomplaints seek rescission of the Merger or rescissory damages, and theTenvold, Klein, Wheby, Sharma, andDaviscomplaints also seek unspecified damages, attorneys’ and expert fees, and expenses and costs. The defendants believe that the complaints are without merit.

The selected unaudited pro forma condensed combined financial information includes the historical results ofII-VI and Finisar after giving pro forma effect to the Merger and other transactions as described in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 170 of this joint proxy statement/prospectus and under “Notes to Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 174 of this joint proxy statement/prospectus.

The selected unaudited pro forma condensed combined financial information was prepared in accordance with Article 11 of RegulationS-X. The selected unaudited pro forma adjustments reflecting the Merger and other transactions described in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 170 of this joint proxy statement/prospectus and under “Notes to Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 174 of this joint proxy statement/prospectus have been prepared in accordance with the acquisition method of accounting in accordance with FASB ASC Topic 805,Business Combinations, whereII-VI is the accounting acquirer and Finisar is the accounting acquiree.

The selected unaudited pro forma condensed combined financial information is provided for illustrative purposes only and does not purport to represent what the actual consolidated results of operations or consolidated financial condition would have been had the Merger actually occurred on the dates indicated, nor do they purport to project the future consolidated results of operations or consolidated financial condition for any future period or as of any future date. The assumed accounting for the Merger, including estimated aggregate Merger Consideration, is based on provisional amounts, and the associated purchase accounting is not final.

COMPARATIVE HISTORICAL AND UNAUDITED PRO FORMA PER SHARE DATA

Historical Per Share Data forII-VI Common Stock and Finisar Common Stock

Finisar’s most recent fiscal year ended on April 29, 2018 andII-VI’s most recent fiscal year ended on June 30, 2018. As a consequence of Finisar’s andII-VI’s different fiscal years, the amounts presented as Finisar’s historical information in the table below for the three months ended September 30, 2018 represent Finisar’s historical information for its three months ended October 28, 2018 and is derived from Finisar’s unaudited condensed consolidated financial statements as of and for the three months ended October 28, 2018. In addition, the amounts presented as Finisar’s historical information in the table below for the year ended June 30, 2018 represent Finisar’s historical information for its 12 months ended July 29, 2018 and is derived by adding the audited consolidated financial statements of Finisar as of and for the year ended April 29, 2018 to the unaudited condensed consolidated financial statements of Finisar as of and for the three months ended July 29, 2018 and deducting the unaudited condensed consolidated financial statements of Finisar as of and for the three months ended July 30, 2017. The historical per share data forII-VI Common Stock below is derived from the audited consolidated financial statements ofII-VI as of and for the year ended June 30, 2018, and the unaudited condensed consolidated financial statements ofII-VI as of and for the three months ended September 30, 2018.

Unaudited Pro Forma Combined Per Share Data forII-VI Common Stock

The unaudited pro forma combined per share data forII-VI Common Stock set forth below gives effect to the Merger, and the estimated financing used to finance the Merger, as if it had been consummated on July 1, 2017, the beginning of the earliest period presented, in the case of earnings per share data, and as of September 30, 2018 in the case of book value per share data, and assuming that each outstanding share of Finisar Common Stock had been converted into 0.2218 shares ofII-VI Common Stock and $15.60 of cash.

The unaudited pro forma combined per share data forII-VI Common Stock has been derived from the audited consolidated financial statements ofII-VI as of and for the year ended June 30, 2018 and the unaudited consolidated financial statements of Finisar as of and for the 12 months ended July 29, 2018, which are calculated by adding the audited consolidated financial statements of Finisar as of and for the year ended April 29, 2018 to the unaudited condensed consolidated financial statements of Finisar as of and for the three months ended July 29, 2018 and deducting the unaudited condensed consolidated financial statements of Finisar as of and for the three months ended July 30, 2017. In addition, the unaudited pro forma combined per share data forII-VI Common Stock has been derived from the unaudited condensed consolidated financial statements ofII-VI as of and for the three months ended September 30, 2018 and the unaudited condensed consolidated financial statements of Finisar as of and for the three months ended October 28, 2018.

The unaudited pro forma combined per share data forII-VI Common Stock has been derived using the acquisition method of accounting. See “Unaudited Pro Forma Condensed Combined Financial Information.” Accordingly, the pro forma adjustments reflect the assets and liabilities of Finisar at their preliminary estimated fair values. Differences between these preliminary estimates and the values finalized within 12 months after the completion of the Merger in accordance with applicable accounting guidance could occur and these differences could have a material impact on the unaudited pro forma combined per share information set forth below.

The unaudited pro forma combined per share data forII-VI Common Stock does not purport to represent the actual results of operations thatII-VI would have achieved had the Merger been completed at the relevant dates used or to project the future results of operations thatII-VI may achieve after the Merger.

Unaudited Pro Forma Combined Per Finisar Equivalent Share Data

The unaudited pro forma combined Finisar equivalent per share data set forth below shows the effect of the Merger from the perspective of an owner of Finisar Common Stock. The information was calculated by

Risk Factors” ofII-VI’s Annual Report on Form10-K for the fiscal year ended June 30, 2018, as updated from time to time inII-VI’s subsequent filings with the SEC, which are incorporated by reference into this joint proxy statement/prospectus, and Finisar’s Annual Report on Form10-K for the fiscal year ended April 29, 2018, as updated from time to time in Finisar’s subsequent filings with the SEC, which are incorporated by reference into this joint proxy statement/prospectus. See the section entitled “Where You Can Find More Information” of this joint proxy statement/prospectus.

Risks Relating to the Merger

The Merger is subject to approval by the shareholders ofII-VI and the stockholders of Finisar.

In order for the Merger to be completed, among other things,II-VI shareholders must approve the Share Issuance Proposal, which requires the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast (assuming a quorum is present), and Finisar stockholders must approve the Merger Proposal, which requires the affirmative vote of holders of a majority of the outstanding shares of Finisar Common Stock at the Finisar Special Meeting. There can be no assurance that either approval will be obtained.

II-VI’s stock price may be negatively impacted by risks, conditions and developments that apply toII-VI, some of which are different from the risks, conditions and developments applicable to Finisar.

Upon completion of the Merger, Finisar stockholders who elect to receive Stock Election Consideration or Mixed Election Consideration will become holders ofII-VI Common Stock, and Finisar stockholders who elect to receive Cash Election Consideration may become holders ofII-VI Common Stock. See “— Finisar stockholders may not receive all consideration in the form they elect.” The businesses and markets ofII-VI are different from those of Finisar in some respects. There is a risk that various factors, conditions and developments that would not affect the price of Finisar Common Stock could negatively affect the price ofII-VI Common Stock. The issuance of shares ofII-VI Common Stock in the Merger could on its own have the effect of depressing the market price forII-VI Common Stock. In addition, many Finisar stockholders may decide not to hold the shares ofII-VI Common Stock they receive as a result of the Merger. Other Finisar stockholders, such as funds with limitations on their permitted holdings of stock in individual issuers, may be required to sell the shares ofII-VI Common Stock they receive as a result of the Merger. Any such sales ofII-VI Common Stock could have the effect of depressing the market price forII-VI Common Stock.

Finisar stockholders may not receive all consideration in the form they elect.

Finisar stockholders that elect to receive Cash Election Consideration or Stock Election Consideration will be subject to proration if holders of Finisar Common Stock, in the aggregate, elect to receive more or less than the aggregate amount of cash consideration orII-VI Common Stock to be paid in the Merger. Accordingly, Finisar stockholders who elect to receive Cash Election Consideration or Stock Election Consideration may instead receive a combination of cash and shares ofII-VI Common Stock if necessary to maintain the aggregate mix of consideration described above. The relative proportion of stock and cash that a Finisar stockholder receives may also have a value that is higher or lower than the relative proportion of stock and cash that the Finisar stockholder elected to receive. A discussion of the proration mechanism can be found under the heading “The Merger Agreement — Merger Consideration” beginning on page 140 of this joint proxy statement/prospectus.

II-VI and Finisar may have difficulty attracting, motivating and retaining executives and other employees in light of the Merger.

Uncertainty about the effect of the Merger onII-VI and Finisar employees may have an adverse effect onII-VI and Finisar and consequently the combined company. This uncertainty may impairII-VI’s and Finisar’s ability to attract, retain and motivate personnel both before and after completion of the Merger.II-VI and Finisar are dependent on the experience and industry knowledge of their officers and other key employees to execute their business plans. The combined company’s success after the Merger will depend in part upon its ability to retain key management personnel and other key employees ofII-VI and Finisar. Employee retention may be particularly challenging during the pendency of the Merger, as employees may feel uncertain about their future roles with the combined company. In addition,II-VI and Finisar may have to provide additional compensation in order to retain employees.

If employees ofII-VI or Finisar depart because of issues relating to the uncertainty and difficulty of integration or a desire not to become employees of the combined company, the combined company’s ability to realize the anticipated benefits of the Merger could be reduced.II-VI may have to incur significant costs in retaining such individuals or in identifying, hiring and retaining replacements for departing employees and may lose significant expertise and talent relating to the business of Finisar, andII-VI’s ability to realize the anticipated benefits of the Merger may be materially and adversely affected. Accordingly, no assurance can be given thatII-VI will be able to attract or retain key employees following the completion of the Merger to the same extent thatII-VI or Finisar has been able to attract or retain employees in the past.

II-VI and Finisar will incur significant transaction-related costs in connection with the Merger.

II-VI and Finisar expect to incur a number ofnon-recurring transaction-related costs associated with completing the Merger, combining the operations of the two companies and achieving desired synergies. These fees and costs will be significant.Non-recurring transaction costs include, but are not limited to, fees paid to legal, financial and accounting advisors, filing fees and printing costs.II-VI will incur significant costs with respect to the financing for the cash consideration to be paid in connection with the Merger. Additional unanticipated costs may be incurred in the integration of the businesses ofII-VI and Finisar. There can be no assurance that the elimination of certain duplicative costs, as well as the realization of other efficiencies related to the integration of the two businesses, will offset the incremental transaction-related costs over time. Thus, any net benefit may not be achieved in the near term, the long term or at all.

Failure to successfully combine the businesses ofII-VI and Finisar in the expected time frame may adversely affect the future results of the combined company, and, consequently, the value of anyII-VI Common Stock that Finisar stockholders receive as part of the Merger Consideration.

The success of the Merger will depend, in part, on the ability ofII-VI to realize the anticipated benefits and synergies from combining the businesses ofII-VI and Finisar. To realize these anticipated benefits, the businesses must be successfully combined. The combined business’s ability to successfully manage this expanded business will depend, in part, upon management’s ability to implement an effective integration of the two companies and its ability to manage a combined business with significantly larger size and scope with the associated increased costs and complexity. If the combined company is not able to achieve these objectives, or is not able to achieve these objectives on a timely basis, the anticipated benefits of the Merger may not be realized fully or at all. In addition, the actual integration may result in additional and unforeseen expenses, which could reduce the anticipated benefits of the Merger. These integration difficulties could result in declines in the market value ofII-VI Common Stock and, consequently, result in declines in the market value of theII-VI Common Stock that Finisar stockholders receive as part of the aggregate Merger Consideration and continue to hold following consummation of the Merger.

49

The Merger is subject to conditions, including certain conditions that may not be satisfied, and may not be completed on a timely basis, or at all. Failure to complete the Merger could have material and adverse effects on Finisar andII-VI.

The completion of the Merger is subject to a number of conditions, including the approval of the Share Issuance Proposal by theII-VI shareholders and approval of the Merger Proposal by the Finisar stockholders, which make the completion and timing of the completion of the Merger uncertain. For more information relating to conditions to completion of the Merger, see the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 160 of this joint proxy statement/prospectus. Also, either Finisar orII-VI may terminate the Merger Agreement if the Merger has not been completed by November 8, 2019; provided that this termination right is not available toII-VI or Finisar, as applicable, ifII-VI’s or Finisar’s, as applicable, failure to comply with the Merger Agreement is a principal cause of or results in the failure of the Merger to occur before November 8, 2019.

If the Merger is not completed on a timely basis, or at all,II-VI’s and Finisar’s respective ongoing businesses may be adversely affected and, without realizing any of the benefits of having completed the Merger,II-VI and Finisar will be subject to a number of risks, including the following:

• II-VI or Finisar may be required to pay the other party a termination fee of $105.2 million in certain circumstances and as described in the section entitled “The Merger Agreement — Fees and Expenses and Termination Fees” beginning on page 163 of this joint proxy statement/prospectus;

• II-VI and Finisar will be required to pay certain costs relating to the Merger, whether or not the Merger is completed, such as legal, accounting, financial advisor and printing fees;

• under the Merger Agreement, each ofII-VI and Finisar is subject to certain restrictions on the conduct of its business prior to completing the Merger, which may adversely affect its ability to execute certain of its business strategies;

• time and resources committed byII-VI’s and Finisar’s respective management to matters relating to the Merger could otherwise have been devoted to pursuing other beneficial opportunities;

• the market price ofII-VI Common Stock or Finisar Common Stock could decline below current market prices to the extent that such current market prices reflect a market assumption that the Merger will be completed; and

• if the Merger Agreement is terminated and the Finisar Board seeks another business combination, stockholders of Finisar cannot be certain that Finisar will be able to find a party willing to enter into a business combination or other strategic transaction on terms equivalent to or more attractive than the terms thatII-VI has agreed to in the Merger Agreement.

In addition, if the Merger is not completed,II-VI and/or Finisar may experience negative reactions from the financial markets and from their respective customers and employees.II-VI and/or Finisar could also be subject to litigation related to any failure to complete the Merger or to enforcement proceedings commenced againstII-VI or Finisar to perform their respective obligations under the Merger Agreement. If the Merger is not completed,II-VI and Finisar cannot assure their respective security holders that the risks described above will not materialize and will not adversely affect the business, financial results and stock prices ofII-VI and/or Finisar.

Lawsuits have been filed against Finisar, the Finisar Board, II-VI, and Merger Sub, and other lawsuits may be filed against Finisar, II-VI, Merger Sub, and/or their respective boards of directors challenging the Merger. An adverse ruling in any such lawsuit may prevent the Merger from being completed.

As of January 17, 2019, six lawsuits have been filed by alleged Finisar stockholders challenging the Merger. The first complaint, a putative class action complaint, was filed by Herbert Hein in the Superior Court of

50

California, County of Santa Clara, and is captionedHein v. Finisar Corporation, et al., 19CV340510. The second complaint, a putative class action complaint, was filed by Pete Tenvold in the United States District Court for the District of Delaware and is captionedTenvold v. Finisar Corporation, et al., 1:19-cv-00050. The third complaint, a putative class action complaint, was filed by Melvyn Klein in the United States District Court for the Northern District of California and is captionedKlein v. Finisar Corporation, et al., 3:19-cv-00155. The fourth complaint, a putative class action complaint, was filed by Earl Wheby, Jr. in the United States District Court for the District of Delaware and is captionedWheby v. Finisar Corporation, et al., 1:19-cv-00064. The fifth complaint was filed by Pankaj Sharma individually in the United States District Court for the Northern District of California and is captionedSharma v. Finisar Corporation, et al.,3:19-cv-00220. The sixth complaint, a putative class action complaint, was filed by William Davis in the United States District Court for the Northern District of California and is captionedDavis v. Finisar Corporation, et al., 3:19-cv-00271.

The complaints name as defendants Finisar and each member of the Finisar Board. In addition, theHein,Tenvold, andKlein complaints name II-VI and Merger Sub as defendants. TheHein,Tenvold,Klein,Wheby, andDavis complaints seek relief on behalf of a putative class defined as all similarly situated Finisar stockholders.

The Heincomplaint alleges that the Finisar Board breached its fiduciary duties to Finisar stockholders by purportedly engaging in an insufficient sales process, obtaining inadequate merger consideration, and filing a materially misleading preliminary proxy statement that does not include, among other things, material information regarding the sales process, financial projections for both Finisar and II-VI, and financial analyses conducted by their financial advisors. TheHein complaint further asserts that II-VI knowingly aided and abetted the Finisar Board in breaching their fiduciary duties to Finisar stockholders by entering into the proposed transaction. TheHeincomplaint seeks preliminary and permanent injunction of the proposed transaction unless the information requested by the plaintiff is disclosed, rescission and unspecified damages if the Merger is consummated, and attorneys’ fees and expert fees and costs.

TheTenvold, Klein, Wheby, Sharma, andDaviscomplaints purport to state claims for violations of Section 14(a) and 20(a) of the Exchange Act and Rule 14a-9 and, in the case of theDavis complaint, Regulation G promulgated thereunder. The plaintiffs in these actions generally allege that the preliminary proxy statement omits material information with respect to the proposed transaction which renders the preliminary proxy statement false and misleading. The plaintiffs in these actions seek an order enjoining the defendants from filing a definitive proxy statement with the SEC or otherwise disseminating a definitive proxy statement to Finisar stockholders or proceeding with closing the Merger unless and until the preliminary proxy statement is cured. In the event the Merger is consummated prior to entry of final judgment, theTenvold, Klein, Wheby, andSharmacomplaintsseek rescission of the Merger or rescissory damages, and theTenvold, Klein, Wheby, Sharma, andDaviscomplaints also seek unspecified damages, attorneys’ and expert fees, and expenses and costs. The defendants believe that the complaints are without merit.

See “The Merger — Litigation Relating to the Merger” beginning on page 137 of this joint proxy statement/prospectus for more information about litigation related to the Merger that has been commenced prior to the date of this joint proxy statement/prospectus. There can be no assurance that additional complaints will not be filed with respect to the Merger.

One of the conditions to completion of the Merger is the absence of any applicable law (including any order) being in effect that prohibits completion of the Merger. Accordingly, if a plaintiff is successful in obtaining an order prohibiting completion of the Merger, then such order may prevent the Merger from being completed, or from being completed within the expected timeframe.

51

In order to complete the Merger,II-VI and Finisar must obtain certain governmental authorizations, and if such authorizations are not granted or are granted with conditions that become applicable to the parties, completion of the Merger may be jeopardized or prevented or the anticipated benefits of the Merger could be reduced.

Completion of the Merger is conditioned upon the expiration or early termination of the waiting period relating to the merger under the HSR Act and certain other applicable laws or regulations and the required governmental authorizations having been obtained and being in full force and effect. AlthoughII-VI and Finisar have agreed in the Merger Agreement to use their reasonable best efforts to cause the closing of the Merger to occur, there can be no assurance that the relevant waiting periods will expire or authorizations will be obtained and no assurance that the Merger will be completed.

The Merger Agreement contains provisions that make it difficult for Finisar to pursue alternatives to the Merger.

Under the Merger Agreement, Finisar is subject to certain restrictions with respect to entering into an alternative transaction to the Merger. Unless and until the Merger Agreement is terminated, subject to specified exceptions (which are discussed in more detail in “The Merger Agreement — Termination of the Merger Agreement” beginning on page 161 of this joint proxy statement/prospectus), Finisar has agreed not to, among other things, (i) solicit, initiate or knowingly encourage or facilitate any inquiries, offers or the making of any proposals or announcement that is or would reasonably be excepted to lead to a takeover proposal, (ii) enter into, continue or otherwise participate in any discussions or negotiations with any third party regarding any takeover proposal or any inquiry that would reasonably be excepted to lead to a takeover proposal, (iii) furnish any nonpublic information regarding itself or any of its subsidiaries to any person in connection with a takeover proposal or any inquiry that would reasonably be expected to lead to a takeover proposal, (iv) release or consent to the release of any confidentiality or similar provisions of any agreement that it is a party to, (v) approve any transaction under Section 203 of the DGCL or (vi) enter into a letter of intent, agreement in principle, memorandum of understanding or other agreement contemplating or otherwise relating to a takeover proposal. Additionally, under the Merger Agreement, in the event of a potential change by the Finisar Board of its recommendation with respect to the Merger in light of a superior proposal, Finisar must provideII-VI with three business days’ prior written notice to allowII-VI to propose an adjustment to the terms and conditions of the Merger Agreement. Finisar may terminate the Merger Agreement and enter into an agreement with respect to a superior proposal only if specified conditions have been satisfied, including compliance with thenon-solicitation and termination provisions of the Merger Agreement. The parties believe these provisions are reasonable and not preclusive of other offers, but these restrictions might discourage a third party that has an interest in acquiring all or a significant part of Finisar from considering or proposing that acquisition, even if that party were prepared to pay consideration with a higher per share value than the per share Merger Consideration. Furthermore, the termination fees described below may result in a potential competing acquirer proposing to pay a lower per share price to acquire the applicable party than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable by such party in certain circumstances.

Under the Merger Agreement, Finisar may be required to pay toII-VI a termination fee of $105.2 million if the Merger Agreement is terminated under specified circumstances. If such a termination fee is payable, the payment of this fee could have material and adverse consequences to the financial condition and operations of Finisar. For a discussion of the restrictions on Finisar entering into a takeover proposal or alternative transaction and the Finisar Board’s ability to change its recommendation, see “The Merger Agreement — No Solicitation of Alternative Proposals,” and “The Merger Agreement — Change of Finisar Board Recommendation” beginning on page 151 and page 153 of this joint proxy statement/prospectus, respectively.

52

Finisar’s executive officers and directors have interests in the Merger that may be different from, or in addition to, the interests of Finisar’s stockholders generally.

Executive officers of Finisar negotiated the terms of the Merger Agreement with their counterparts atII-VI, and the Finisar Board, by unanimous vote, approved and declared advisable the Merger Agreement and the other transactions contemplated thereby, including the Merger, and determined that the terms of the Merger Agreement, the Merger and the other transactions contemplated thereby are fair to and in the best interests of Finisar and its stockholders. In considering these facts and the other information contained in this joint proxy statement/prospectus, Finisar stockholders should be aware that aside from their interests as stockholders, Finisar’s executive officers and directors may have employment and other compensation arrangements or plans that give them financial interests in the Merger that may be different from, or in addition to, the interests of Finisar stockholders. For a further description of these interests see the section entitled “Interests of Finisar’s Directors and Executive Officers in the Merger” beginning on page 166 of this joint proxy statement/prospectus.

The opinion of Finisar’s financial advisor speaks only as of the date of such opinion and does not reflect changes in events or circumstances that may occur between the original signing of the Merger Agreement and the completion of the Merger.

Consistent with market practices, the Finisar Board has not obtained an updated opinion from its financial advisor as of the date of this joint proxy statement/prospectus and does not expect to receive an updated, revised or reaffirmed opinion prior to the completion of the Merger. The opinion does not speak as of the time the Merger will be completed or as of any date other than the date of such opinion. Changes in the operations and prospects of Finisar orII-VI, general market and economic conditions and other factors which may be beyond the control of Finisar orII-VI and on which Finisar’s financial advisor’s opinion was based, may significantly alter the value of Finisar orII-VI or the price of shares of Finisar Common Stock or shares ofII-VI Common Stock by the time the Merger is completed. Because Finisar’s financial advisor will not be updating its opinion, the opinion will not address the fairness of the Merger Consideration from a financial point of view at the time the Merger is completed. For a description of the opinion that Finisar received from its financial advisor, see the section entitled “The Merger — Opinion of Finisar’s Financial Advisor” beginning on page 102 of this joint proxy statement/prospectus.

The opinion rendered to theII-VI Board by its financial advisor, BofA Merrill Lynch, speaks only as of the date of such opinion. BofA Merrill Lynch’s opinion does not reflect changes in events or circumstances after the date of its opinion.II-VI has not obtained, and does not expect to obtain, an updated fairness opinion reflecting changes in circumstances that may have occurred since such date.

On November 8, 2018, at a meeting of theII-VI Board held to evaluate the Merger, BofA Merrill Lynch delivered to theII-VI Board its oral opinion, which was confirmed by delivery of a written opinion dated November 8, 2018, with respect to the fairness, from a financial point of view, of the Merger Consideration toII-VI. Consistent with market practices, theII-VI Board has not obtained an updated opinion from its financial advisor as of the date of this joint proxy statement/prospectus and does not expect to receive an updated, revised or reaffirmed opinion prior to the completion of the Merger. The opinion delivered by BofA Merrill Lynch to theII-VI Board does not speak as of any date other than the date of such opinion. Changes in the operations and prospects of Finisar orII-VI, general market and economic conditions and other factors which may be beyond the control of Finisar orII-VI may have altered since the date of BofA Merrill Lynch’s opinion, and may alter in the future, the values of Finisar orII-VI or the prices of Finisar Common Stock orII-VI Common Stock. BofA Merrill Lynch has no obligation or duty to update its opinion, andII-VI does not expect to obtain an updated fairness opinion, to take into account any such changes. For a summary description of BofA Merrill Lynch’s opinion, see the section entitled “The Merger — Opinion ofII-VI’s Financial Advisor” beginning on page 112 of this joint proxy statement/prospectus.

53

The closing of the Merger may trigger change in control provisions in certain agreements to which Finisar is a party.

The closing of the Merger may trigger change in control provisions in certain agreements to which Finisar is a party. If Finisar andII-VI are unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under the agreements, potentially terminating the agreements or seeking monetary damages. Even if Finisar andII-VI are able to negotiate waivers, the counterparties may require a fee for such waiver or seek to renegotiate the agreements on terms less favorable to Finisar or the combined company.

Each of Finisar andII-VI is subject to business uncertainties and contractual restrictions while the Merger is pending, which could adversely affect each of Finisar’s andII-VI’s business and operations.

Under the terms of the Merger Agreement, Finisar andII-VI are subject to certain restrictions on the conduct of their respective business prior to completing the Merger, which may adversely affect each party’s ability to execute certain of its business strategies. Such limitations could negatively affect each party’s businesses and operations prior to the completion of the Merger. Furthermore, the process of planning to integrate two businesses and organizations for the post-Merger period can divert management attention and resources and could ultimately have an adverse effect on each of Finisar andII-VI.

In connection with the Merger, parties with which Finisar orII-VI does business may experience uncertainty associated with the Merger, including with respect to current or future business relationships with Finisar,II-VI or the combined business. It is possible that some customers, suppliers and other persons with whom Finisar orII-VI has a business relationship may delay or defer certain business decisions or might decide to seek to terminate, change or renegotiate their relationships with Finisar orII-VI, as applicable, as a result of the Merger, which could negatively affect Finisar’s orII-VI’s revenues, earnings and cash flows, as well as the market price of shares of its common stock, regardless of whether the Merger is completed.

The exchange ratios are fixed and because the market price ofII-VI Common Stock and Finisar Common Stock will fluctuate, Finisar stockholders receivingII-VI Common Stock as part of the Merger Consideration cannot be sure of the market value of such Merger Consideration relative to the value of their shares of Finisar Common Stock that they are exchanging.

If the Merger is completed, each share of Finisar Common Stock (other than Dissenting Stockholder Shares and Excluded Shares) will be converted into the right to receive either $26.00 in cash (without any interest thereon), 0.5546 shares ofII-VI Common Stock or a combination of $15.60 in cash (without any interest thereon) and 0.2218 shares ofII-VI Common Stock (subject to the adjustment and proration procedures described in further detail in the section entitled “The Merger Agreement — Merger Consideration” beginning on page 140 of this joint proxy statement/prospectus). During the pendency of the Merger, the market value ofII-VI Common Stock will fluctuate, and decreases in the market value ofII-VI Common Stock will negatively affect the value of the Merger Consideration that Finisar stockholders receive. The market value of Finisar Common Stock will also fluctuate during the pendency of the Merger, and increases in the market value of Finisar Common Stock may mean that the Merger Consideration issued to Finisar stockholders will be worth less than the market value of the shares of Finisar Common Stock such stockholders are exchanging. The exchange ratios were fixed at the time the Merger Agreement was executed, and the value ofII-VI Common Stock and Finisar Common Stock may vary significantly from their values on the date of the Merger Agreement, the date of this joint proxy statement/prospectus, the date on whichII-VI shareholders vote on the Share Issuance Proposal, the date on which Finisar stockholders vote on the Merger Proposal, the date on which Finisar stockholders make their election and the date on which Finisar stockholders receive the applicable Merger Consideration. Neither Finisar norII-VI is permitted to terminate the Merger Agreement solely due to changes in the market price of either party’s common stock.

There will be a period of time between the date on which Finisar stockholders make an election with respect to the form of Merger Consideration to be received by them in exchange for their Finisar Common Stock and the

54

date on which Finisar stockholders actually receiveII-VI Common Stock, depending on their election and subject to proration. Fluctuations in the market value ofII-VI Common Stock during this time period will also affect the value of the Merger Consideration, once it is actually received.

If a Finisar stockholder elects to receive Stock Election Consideration or Mixed Election Consideration and the market value ofII-VI Common Stock falls between the time of the election and the time the applicable Merger Consideration is actually received, the value of the Merger Consideration received may be less than the value of the Merger Consideration such stockholder would have received if they had elected to receive Cash Election Consideration. Conversely, if a Finisar stockholder elects to receive Cash Election Consideration and the market value ofII-VI Common Stock rises between the time of the election and the time the applicable Merger Consideration is actually received, the value of the Merger Consideration received may be less than the value of the Merger Consideration such stockholder would have received if they had elected to receive Stock Election Consideration or Mixed Election Consideration. Finisar stockholders are urged to obtain current market quotations forII-VI Common Stock when they make their elections.

The unaudited pro forma financial information included in this joint proxy statement/prospectus may not necessarily reflect the combined company’s operating results and financial condition following the Merger.

The unaudited pro forma condensed combined financial information included in this joint proxy statement/prospectus is derived fromII-VI’s and Finisar’s separate historical consolidated financial statements. The preparation of this pro forma information is based upon available information and certain assumptions and estimates thatII-VI and Finisar currently believe are reasonable. These assumptions and estimates may not prove to be accurate, and this pro forma financial information does not necessarily reflect what the combined company’s results of operations and financial position would have been had the Merger been completed on the relevant dates assumed and the assumptions and estimates were to prove accurate, or what the combined company’s results of operations or financial position will be in the future.

Finisar’s financial estimates are based on various assumptions that may not prove to be correct.

The financial estimates set forth in the forecast included under “The Merger — Unaudited Prospective Financial Information” are based on assumptions of, and information available to, Finisar at the time they were prepared and provided to the Finisar Board and to Barclays, as Finisar’s financial advisor. Finisar does not know whether the assumptions they made will prove correct. Any or all of such estimates may turn out to be wrong. They can be adversely affected by inaccurate assumptions or by known or unknown risks and uncertainties, many of which are beyond Finisar’s control. Many factors mentioned in this joint proxy statement/prospectus and Finisar’s other filings with the SEC incorporated by reference into this joint proxy statement/prospectus, including the risks outlined in this “Risk Factors” section and in Finisar’s public filings and the events and/or circumstances described under “Cautionary Statement Regarding Forward-Looking Statements” will be important in determining Finisar’s future results. See also, “Where You Can Find More Information.” As a result of these contingencies, actual future results may vary materially from Finisar’s estimates.

CurrentII-VI shareholders and Finisar stockholders will have a reduced ownership and voting interest inII-VI after the Merger.

Upon the completion of the Merger, each Finisar stockholder who receives consideration in the form ofII-VI Common Stock and eachII-VI shareholder will have a percentage ownership ofII-VI that is smaller than such stockholder’s previous percentage ownership of Finisar orII-VI, as applicable. Based on the number of shares of Finisar Common Stock outstanding as of                 , 2019, and the number of shares ofII-VI Common Stock outstanding as of                 , 2019, and assuming no adjustment in the number of shares ofII-VI Common Stock to be issued as aggregate Merger Consideration in connection with the Merger Agreement, and assuming no conversions of the Finisar Convertible Notes, it is expected that, immediately after completion of the Merger, former holders of Finisar Common Stock and Finisar equity awards will own approximately     % of the outstanding shares ofII-VI Common Stock. As a result of these reduced ownership percentages, each ofII-VI shareholders and Finisar stockholders, as a group, will have less voting power in, and influence on the board of directors, management and policies of,II-VI following the Merger than they now have in their respective companies.

56

The shares ofII-VI Common Stock to be received by Finisar stockholders upon completion of the Merger will have different rights from shares of Finisar Common Stock.

Upon completion of the Merger, Finisar stockholders will no longer be stockholders of Finisar, a Delaware corporation, but will instead become shareholders ofII-VI, a Pennsylvania corporation. As such, their rights asII-VI shareholders will be governed by Pennsylvania law and the terms of theII-VI Charter, as it may be amended from time to time, and theII-VIBy-Laws, as they may be amended from time to time. Pennsylvania law and the terms of theII-VI Charter and theII-VIBy-Laws are in some respects materially different than Delaware law and the terms of the Finisar Charter and the Finisar Bylaws, as they may be amended from time to time, which currently govern the rights of Finisar Stockholders. See “Comparison of Shareholders’ Rights” beginning on page 196 of this joint proxy statement/prospectus for a discussion of the different rights associated with shares of Finisar Common Stock and shares ofII-VI Common Stock.

No assurance can be provided thatII-VI will be able to consummate theII-VI Senior Credit Facilities or obtain alternative financing to fund the cash portion of the aggregate Merger Consideration to be paid in connection with the Merger.

The completion of the Merger is not subject to a financing condition. The receipt of any financing byII-VI is not a condition to completion of the Merger and, except in certain limited circumstances in whichII-VI or Finisar may be permitted to terminate the Merger Agreement (as more fully described in “The Merger Agreement — Termination of the Merger Agreement” beginning on page 161 of this joint proxy statement/prospectus),II-VI will be required to complete the Merger (assuming that all of the conditions to its obligations to complete the Merger under the Merger Agreement are satisfied or waived) whether or not financing is available on acceptable terms or at all.

On November 8, 2018, in connection with its entry into the Merger Agreement,II-VI entered into the Commitment Letter, which was subsequently amended and restated on December 7, 2018 and on December 14, 2018. Subject to the terms and conditions set forth in the Commitment Letter, the Lending Parties have severally committed to provide 100% of up to $2.425 billion in aggregate principal amount of theII-VI Senior Credit Facilities, comprised of (i) a “term a” loan facility of up to $1.0 billion, a portion of which will be available after the closing of the Merger on a delayed draw basis, (ii) a “term b” loan facility of up to $975.0 million and (iii) a revolving credit facility of up to $450.0 million.II-VI currently intends to pay the cash portion of the aggregate Merger Consideration and pay related fees and expenses in connection with the Merger using the proceeds of draws under theII-VI Senior Credit Facilities and cash and short-term investments ofII-VI and Finisar.II-VI currently does not intend to draw on the revolving credit facility in order to fund the cash portion of the aggregate Merger Consideration.

The commitments of the Lead Arrangers with respect to theII-VI Senior Credit Facilities will automatically terminate at 11:59 p.m., New York City time, on the first to occur of (i) November 8, 2019 (unless the Merger occurs on or prior thereto), (ii) the date of closing of the Merger without the use of proceeds from theII-VI Senior Credit Facilities or (iii) the date on whichII-VI delivers written notice to terminate its obligations under the Merger Agreement pursuant to the terms thereof or the date that the Merger Agreement is terminated.

The documentation governing theII-VI Senior Credit Facilities has not been finalized and, accordingly, the actual terms of theII-VI Senior Credit Facilities may differ from those described herein or in the Commitment Letter as a result of the syndication process. Although the debt financing described in this joint proxy statement/prospectus is not subject to a due diligence or “market out,” such financing may not be considered assured. The obligation of the Lead Arrangers to provide the debt financing under the Commitment Letter is subject to a number of conditions. There is a risk that these conditions will not be satisfied and theII-VI Senior Credit Facilities may not be funded when required or at all. As of the date of this joint proxy statement/prospectus, no alternative financing arrangements have been made in the event theII-VI Senior Credit Facilities are not available, and any such alternative financing arrangements may not be available on acceptable terms, or at all, if theII-VI Senior Credit Facilities are not consummated.

Risk Factors Relating to the Combined Company Following the Merger

AlthoughII-VI expects that its acquisition of Finisar will result in cost savings, synergies and other benefits, the combined company may not realize those benefits because of integration difficulties and other challenges.

The success ofII-VI’s acquisition of Finisar will depend in large part on the success of the management of the combined company in integrating the operations, strategies, technologies and personnel of the two companies following the completion of the Merger. The combined company may fail to realize some or all of the anticipated benefits of the Merger if the integration process takes longer than expected or is more costly than expected. The failure of the combined company to meet the challenges involved in successfully integrating the operations of the two companies or to otherwise realize any of the anticipated benefits of the Merger, including additional cost savings and synergies, could impair the operations of the combined company. In addition,II-VI anticipates that the overall integration of Finisar will be a time-consuming and expensive process that, without proper planning and effective and timely implementation, could significantly disrupt the combined company’s business.

Potential difficulties the combined company may encounter in the integration process include the following:

• the integration of management teams, strategies, technologies and operations, products and services;

• the disruption of ongoing businesses and distraction of their respective management teams from ongoing business concerns;

• the retention of and possible decrease in business from the existing customers of both companies;

• the creation of uniform standards, controls, procedures, policies and information systems;

• the reduction of the costs associated with each company’s operations;

• the integration of corporate cultures and maintenance of employee morale;

• the retention of key employees; and

• potential unknown liabilities associated with the Merger.

The anticipated cost savings, synergies and other benefits of the Merger assume a successful integration of the companies and are based on projections and other assumptions, which are inherently uncertain. Even if integration is successful, anticipated cost savings, synergies and other benefits may not be achieved.

The market price ofII-VI Common Stock may decline in the future as a result of the Merger.

The market price ofII-VI Common Stock may decline in the future as a result of the Merger for a number of reasons, including:

• the unsuccessful integration of Finisar andII-VI (including for the reasons set forth in the preceding risk factor);

• the need to pay cash amounts owing on conversion of, or in respect of any demands for repurchase of, the Finisar Convertible Notes in connection with the Merger and to issueII-VI Common Stock in connection with any future conversion of the Finisar Convertible Notes, which may cause substantial dilution to holders ofII-VI Common Stock; and

• the failure of the combined company to achieve the perceived benefits of the Merger, including financial results, as rapidly as or to the extent anticipated by financial or industry analysts.

These factors are, to some extent, beyond the control ofII-VI. As a consequence, currentII-VI shareholders and Finisar stockholders who become holders ofII-VI Common Stock after completion of the Merger could lose the value of their investment inII-VI Common Stock.

58

The Merger may not be accretive and may cause dilution to the combined company’s earnings per share, which may negatively affect the market price of theII-VI Common Stock.

II-VI currently anticipates that the Merger will be accretive to earnings per share (on an adjusted earnings basis) during the first full calendar year after the Merger. This expectation is based on preliminary estimates which may materially change. The combined company could also encounter additional transaction-related costs or other factors such as the failure to realize all of the benefits anticipated in the Merger. All of these factors could cause dilution to the combined company’s earnings per share or decrease or delay the expected accretive effect of the Merger and cause a decrease in the market price ofII-VI Common Stock.

The combined company’s future results will suffer if it does not effectively manage its expanded operations following the Merger.

Following the Merger, the size of the business of the combined company will increase significantly beyond the current size of eitherII-VI’s or Finisar’s current businesses. The combined company’s future success depends, in part, upon its ability to manage this expanded business, which may pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurance that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the Merger.

II-VI and Finisar face competition, which is expected to intensify and which may reduce the market share and profits ofII-VI after consummation of the Merger.

Competition in the industries in whichII-VI and Finisar operate is intense. Increased competition could hurtII-VI’s and Finisar’s businesses, hinder their market share expansion and lead to pricing pressures that may adversely impact their margins and revenues. If the combined company is unable to successfully compete following the Merger, its business, prospects, liquidity, financial condition and results of operations could be materially and adversely affected.

Following the consummation of the Merger, the combined company’s competitive position could be weakened by strategic alliances or consolidation within the combined company’s industries or the development of new technologies by competitors. The combined company’s ability to compete successfully will depend on how well it markets its products and services and on its ability to anticipate and respond to various competitive factors affecting its industries, including changes in customer preferences, and changes in the product offerings or pricing strategies of the combined company’s competitors.

After the consummation of the Merger, competition could materially adversely affect the combined company in several ways, including (i) the loss of customers and market share, (ii) the combined company’s need to lower prices or increase expenses to remain competitive and (iii) the loss of business relationships withinII-VI’s existing markets.

II-VI is expected to incur substantial expenses related to the Merger and integration.

II-VI is expected to incur substantial expenses in connection with the Merger and the related integration. There are a large number of processes, policies, procedures, operations, technologies and systems that may need to be integrated, including purchasing, accounting and finance, sales, payroll, pricing and benefits.

WhileII-VI has assumed that a certain level of expenses will be incurred, there are many factors beyond its control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings thatII-VI expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses likely will result

59

in the combined company taking significant charges against earnings following the completion of the Merger, and the amount and timing of such charges are uncertain at present.

Following the consummation of the Merger,II-VI will be bound by all of the obligations and liabilities of both companies.

Following the consummation of the Merger, the combined company will become bound by all of the obligations and liabilities of Finisar in addition toII-VI’s obligations and liabilities existing prior to the consummation of the Merger. NeitherII-VI nor Finisar can predict the financial condition of the combined company at the time of the combination or the ability of the combined company to satisfy its obligations and liabilities.

The Merger may result in a loss of suppliers and strategic alliances and may result in the termination of existing contracts.

Following the Merger, some of the suppliers ofII-VI or Finisar, as historical businesses, may terminate or scale back their business relationship with the combined company.II-VI and Finisar have contracts with suppliers, vendors, and other business partners which may requireII-VI or Finisar to obtain consents from these other parties in connection with the Merger, which may not be obtained at all or on favorable terms. If supplier relationships or strategic alliances are adversely affected by the Merger, or if the combined company, following the Merger, loses the benefits of the contracts ofII-VI or Finisar, the combined company’s business and financial performance could suffer.

Following the Merger, the combined company will have a substantial amount of debt, which could adversely affect its business, financial condition or results of operations and prevent it from fulfilling its debt-related obligations.

Following the Merger, the combined company will have a substantial amount of debt. As of September 30, 2018, on a pro forma basis, the combined company would have had approximately $2.2 billion of outstanding debt (including under its outstanding debt securities and borrowings underII-VI’s credit facilities). The combined company’s substantial debt could have important consequences for the holders ofII-VI Common Stock, including:

• making it more difficult for the combined company to satisfy its obligations with respect to its debt or to its trade or other creditors;

• increasing the combined company’s vulnerability to adverse economic or industry conditions;

• limiting the combined company’s ability to obtain additional financing to fund capital expenditures and acquisitions, particularly when the availability of financing in the capital markets is limited;

• requiring the combined company to pay higher interest rates upon refinancing or on the combined company’s variable rate indebtedness if interest rates rise;

• requiring a substantial portion of the combined company’s cash flows from operations and the proceeds of any capital markets offerings or loan borrowings for the payment of interest on the combined company’s debt and reducing the combined company’s ability to use its cash flows to fund working capital, capital expenditures, acquisitions and general corporate requirements;

• limiting the combined company’s flexibility in planning for, or reacting to, changes in its business and the industries in which it operates; and

• placing the combined company at a competitive disadvantage to less leveraged competitors.

The combined company may not generate sufficient cash flow from operations, together with any future borrowings, to enable the combined company to pay its indebtedness, or to fund the combined company’s other

60

liquidity needs. The combined company may need to refinance all or a portion of its indebtedness, on or before its maturity. The combined company may not be able to refinance any of its indebtedness on commercially reasonable terms or at all. The combined company may not be able to pay the repurchase price on the 2033 Notes and 2036 Notes to the extent holders elect to exercise their repurchase rights in December 2023 and 2028 with respect to the 2033 Notes and December 2026 and 2031 with respect to the 2036 Notes. In addition, the combined company may incur additional indebtedness in order to finance its operations, to fund acquisitions, or to repay existing indebtedness. If the combined company cannot service its indebtedness, it may have to take actions such as selling assets, seeking additional debt or equity or reducing or delaying capital expenditures, strategic acquisitions, investments and alliances. Any such actions, if necessary, may not be able to be effected on commercially reasonable terms or at all, or on terms that would be advantageous to the combined company’s stockholders or on terms that would not requireII-VI to breach the terms and conditions of its existing or future debt agreements.

Other Risk Factors Relating toII-VI and Finisar

As a result of entering into the Merger Agreement,II-VI’s and Finisar’s businesses are and will be subject to the risks described above. In addition,II-VI and Finisar are, and following completion of the Merger, the combined company will continue to be, subject to the risks described inII-VI’s Annual Report on Form10-K for the fiscal year ended June 30, 2018 and Finisar’s Annual Report on Form10-K for the fiscal year ended April 29, 2018, each as updated by subsequent Quarterly Reports on Form10-Q and Current Reports on Form8-K, all of which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus.

Record Date, Outstanding Shares and Quorum

Finisar has set the close of business on                , 2019 as the record date for the Finisar Special Meeting (the “Finisar Record Date”), and only Finisar stockholders of record on the Finisar Record Date are entitled to notice of, and vote at, the Finisar Special Meeting and any adjournments or postponements thereof. As of the close of business on the Finisar Record Date, there were                shares of Finisar Common Stock outstanding held by approximately                holders of record.

The presence, in person or represented by proxy, of a majority of the shares of Finisar Common Stock issued and outstanding on the Finisar Record Date will constitute a quorum at the Finisar Special Meeting. Abstentions are considered as present for purposes of establishing a quorum. There must be a quorum for the votes on the Merger Proposal, the Adjournment Proposal, and the Compensation Proposal to be taken at the Finisar Special Meeting. If there is no quorum, the Finisar Special Meeting may be adjourned or postponed to another date, which may subject Finisar to additional expense and delay or prevent the completion of the Merger. If a quorum shall fail to attend the Finisar Special Meeting, the chairman of the meeting or the holders of a majority of the shares of Finisar Common Stock entitled to vote who are present, in person or by proxy, may adjourn the meeting to another place, date, or time.

If your shares of Finisar Common Stock are not voted on the Merger Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Merger Proposal, your shares will have the effect of a vote “AGAINST” the Merger Proposal.Finisar cannot complete the Merger, and no Merger Consideration will be paid to Finisar stockholders byII-VI, unless, among other things, the Finisar stockholders approve the Merger Proposal.

66

Assuming that a quorum is present, approval of the Finisar Adjournment Proposal requires the affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting. If your shares of Finisar Common Stock are not voted on the Finisar Adjournment Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Finisar Adjournment Proposal, your shares will have no effect on the Finisar Adjournment Proposal.

Assuming that a quorum is present, approval of the Compensation Proposal requires the affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting. If your shares of Finisar Common Stock are not voted on the Compensation Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Compensation Proposal, your shares will have no effect on the Compensation Proposal.

If your shares are held in the name of a bank, brokerage firm or other nominee, you are considered the “beneficial holder” of the shares held for you in what is known as “street name.” You are not the “record holder” of such shares. If this is the case, this joint proxy statement/prospectus has been forwarded to you by your bank, brokerage firm or other nominee. Unless your bank, brokerage firm or other nominee has discretionary authority to vote your shares, your bank, brokerage firm or other nominee may not vote your shares without voting instructions from you. Under applicable stock exchange rules, if your shares are held in “street name” through a brokerage firm, your brokerage firm has discretionary authority to vote on “routine” proposals if you have not provided voting instructions. However, your brokerage firm is precluded from exercising voting discretion with respect tonon-routine matters. All of the proposals to be voted on by Finisar stockholders at the Finisar Special Meeting arenon-routine matters. As a result, if you do not provide voting instructions, your shares will not be voted on any proposal at the Finisar Special Meeting.

You should therefore provide your bank, brokerage firm or other nominee with instructions as to how to vote your shares of Finisar Common Stock.If you do not give your bank, brokerage firm or other nominee instructions, your shares will not be votedat the Finisar Special Meeting. You areencouraged to provide instructions toyour bank, brokerage firm or other nominee. This ensures your shares will be voted at the Finisar Special Meeting.Please follow the voting instructions provided by your bank, brokerage firm or other nominee so that it may vote your shares on your behalf. Please note that you may not vote shares held in street name by returning a proxy card directly to Finisar or by voting in person at the Finisar Special Meeting unless you first obtain a proxy from your bank, brokerage firm or other nominee.

As of the Finisar Record Date, the directors and executive officers of Finisar and their affiliates beneficially owned, in the aggregate,                shares of Finisar Common Stock, representing approximately     % of the outstanding shares of Finisar Common Stock as of the close of business on the Finisar Record Date entitled to vote at the Finisar Special Meeting and any adjournments or postponements thereof. The directors and executive officers of Finisar have informed Finisar that they currently intend to vote all such shares of Finisar Common Stock entitled to vote “FOR” the Merger Proposal, “FOR” the Finisar Adjournment Proposal, and “FOR” the Compensation Proposal.

Adjournments and Postponements

Although it is not currently expected, the Finisar Special Meeting may be adjourned or postponed on one or more occasions for the purpose of soliciting additional proxies if there are insufficient votes at the time of the Finisar Special Meeting to adopt the Merger Proposal or if a quorum is not present at the Finisar Special Meeting. Any adjournment of the Finisar Special Meeting for the purpose of soliciting additional proxies will allow Finisar stockholders who have already sent in their proxies to revoke them at any time prior to their use at the Finisar Special Meeting as adjourned or postponed.

Finisar may also postpone or adjourn the Finisar Special Meeting to allow reasonable additional time for the filing or mailing of any supplemental or amended disclosure required under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by Finisar stockholders prior to the Finisar Special Meeting.

If a quorum is present at the Finisar Special Meeting, the Finisar Special Meeting may be adjourned if the Adjournment Proposal is approved.

If a quorum is not present at the Finisar Special Meeting, an adjournment of the meeting generally may be made by the chair of the Finisar Special Meeting or by a majority of the shares of Finisar Common Stock entitled to vote who are present, in person or by proxy. In the event there is not a quorum present, Finisar anticipates the chair of the Finisar Special Meeting will exercise his or her authority to adjourn the meeting.

Solicitation of Proxies; Payment of Solicitation Expenses

This joint proxy statement/prospectus is being provided to holders of shares of Finisar Common Stock in connection with the solicitation of proxies by the Finisar Board to be voted at the Finisar Special Meeting and at any adjournments or postponements of the Finisar Special Meeting. Finisar will bear all costs and expenses in connection with the solicitation of proxies, including the costs of filing, printing and mailing this joint proxy statement/prospectus for the Finisar Special Meeting. Finisar has engaged D.F. King & Co., Inc. to aid in the solicitation of proxies from brokers, bank nominees and other institutional owners for approximately $12,500, plus reimbursement of related expenses.

Finisar may reimburse banks, brokerage firms, other nominees or their respective agents for their expenses in forwarding proxy materials to beneficial owners of Finisar Common Stock. Finisar’s directors, officers and employees also may solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

Appraisal Rights

Pursuant to Section 262 of the DGCL, a Finisar stockholder who chooses the Stock Election Consideration for his, her or its shares of Finisar Common Stock, but receives a mix of cash andII-VI Common Stock for such shares due to an oversubscription of the Stock Election Consideration through the proration adjustment mechanism, will be entitled to appraisal rights for such shares if such stockholder otherwise complies with the requirements of Section 262 of the DGCL.APPRAISAL RIGHTS WILL NOT BE AVAILABLE TO FINISAR STOCKHOLDERS WHO FAIL TO MAKE AN ELECTION AND RECEIVE THE MIXED ELECTION CONSIDERATION OR TO FINISAR STOCKHOLDERS WHO CHOOSE THE CASH ELECTION CONSIDERATION OR THE MIXED ELECTION CONSIDERATION. THE ONLY CIRCUMSTANCES IN WHICH A FINISAR STOCKHOLDER MAY BE ENTITLED TO APPRAISALRIGHTS IS IF SUCH STOCKHOLDER CHOOSES THE STOCK ELECTION CONSIDERATION BUT RECEIVES A COMBINATION OFII-VI COMMON STOCK AND CASH THROUGH THE PRORATION MECHANISMS DUE TO AN OVERSUBSCRIPTION OF THE STOCK ELECTION CONSIDERATION.

69

Finisar stockholders who wish to exercise the right to seek an appraisal of their shares must not vote in favor of the Merger Proposal nor consent thereto in writing, must continuously hold their shares of Finisar Common Stock through the effective date of the Merger, must deliver to Finisar a written demand for appraisal prior to the date of the Finisar Special Meeting and must otherwise comply with the applicable requirements of Section 262 of the DGCL. The appraisal remedy affords eligible Finisar stockholders the right to seek appraisal of the fair value of their shares of Finisar Common Stock, as determined by the Delaware Court of Chancery, if the Merger is completed. The “fair value” of shares of Finisar Common Stock as determined by the Delaware Court of Chancery could be greater than, the same as, or less than the value of the Merger Consideration that Finisar stockholders would otherwise be entitled to receive under the terms of the Merger Agreement.

The right to seek appraisal will be lost if a Finisar stockholder votes “FOR” the Merger Proposal. However, abstaining or voting against the Merger Proposal is not in itself sufficient to perfect appraisal rights because additional actions must also be taken to perfect such rights.

Finisar stockholders who wish to exercise the right to seek an appraisal of their shares must so advise Finisar by submitting a written demand for appraisal prior to the taking of the vote on the Merger Proposal at the Finisar Special Meeting, and must otherwise follow the procedures prescribed by Section 262 of the DGCL. These procedures are summarized in the section entitled “Appraisal Rights” beginning on page 215 of this joint proxy statement/prospectus. A person having a beneficial interest in shares of Finisar Common Stock held of record in the name of another person, such as a nominee or intermediary, must act promptly to cause the record holder to follow the steps required by Section 262 of the DGCL and in a timely manner to perfect appraisal rights. In view of the complexity of Section 262 of the DGCL, Finisar stockholders that may wish to pursue appraisal rights are urged to consult their legal and financial advisors. However, notwithstanding a Finisar stockholder’s compliance with the DGCL, in perfecting appraisal rights, under Section 262 of the DGCL, assuming Finisar Common Stock remains listed on a national securities exchange immediately prior to the Effective Time, the Delaware Court of Chancery will dismiss any appraisal proceedings as to all stockholders who are otherwise entitled to appraisal rights unless (i) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of Finisar Common Stock, or (ii) the value of the consideration provided in the Merger for the total number of shares of Finisar Common Stock entitled to appraisal exceeds $1 million.

Vote Required

Assuming that a quorum is present, approval of the Share Issuance Proposal requires the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast. Accordingly, abstentions will have the same effect as a vote “AGAINST” the Share Issuance Proposal, but shares deemed not in attendance at the meeting, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary will have no effect on the Share Issuance Proposal. This vote will satisfy the vote requirements of Listing Rule 5635(d) of the Nasdaq Stock Market with respect to the Share Issuance Proposal.II-VI cannot complete the Merger unless, among other things, theII-VI shareholders approve the Share Issuance Proposal.

Approval of theII-VI Adjournment Proposal requires the affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast, whether or not a quorum is present. Accordingly, abstentions will have the same effect as a vote “AGAINST” theII-VI Adjournment Proposal, but shares deemed not in attendance at the meeting, whether due to a record

72

holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary will have no effect on theII-VI Adjournment Proposal.

If your shares are held in the name of a bank, brokerage firm or other nominee, you are considered the “beneficial holder” of the shares held for you in what is known as “street name.” You are not the “record holder” of such shares. If this is the case, this joint proxy statement/prospectus has been forwarded to you by your bank, brokerage firm or other nominee. Unless your bank, brokerage firm or other nominee has discretionary authority to vote your shares, your bank, brokerage firm or other nominee may not vote your shares without voting instructions from you. Under applicable stock exchange rules, if your shares are held in “street name” through a brokerage firm, your brokerage firm has discretionary authority to vote on “routine” proposals if you have not provided voting instructions. However, your brokerage firm is precluded from exercising voting discretion with respect tonon-routine matters. All of the proposals to be voted on byII-VI shareholders at theII-VI Special Meeting arenon-routine matters. As a result, if you do not provide voting instructions, your shares will not be voted on any proposal at theII-VI Special Meeting.

You should therefore provide your bank, brokerage firm or other nominee with instructions as to how to vote your shares ofII-VI Common Stock.If you do not give your bank, brokerage firm or other nominee instructions, your shares will not be voted at theII-VI Special Meeting. You are encouraged to provide instructions to your bank, brokerage firm or other nominee. This ensures your shares will be voted at theII-VI Special Meeting.Please follow the voting instructions provided by your bank, brokerage firm or other nominee so that it may vote your shares on your behalf. Please note that you may not vote shares held in street name by returning a proxy card directly toII-VI or by voting in person at theII-VI Special Meeting unless you first obtain a proxy from your bank, brokerage firm or other nominee.

As of theII-VI Record Date, the directors and executive officers ofII-VI and their affiliates beneficially owned, in the aggregate,                shares ofII-VI Common Stock, representing approximately     % of the outstanding shares ofII-VI Common Stock as of the close of business on theII-VI Record Date entitled to vote at theII-VI Special Meeting and any adjournments or postponements thereof. The directors and executive officers ofII-VI have informedII-VI that they currently intend to vote all such shares ofII-VI Common Stock entitled to vote “FOR” the Share Issuance Proposal and “FOR” theII-VI Adjournment Proposal.

For additional information about the Merger, see “The Merger Agreement — Structure and Effects of the Merger” and “The Merger Agreement — Merger Consideration” beginning on pages 139 and 140, respectively, of this joint proxy statement/prospectus.

At the Effective Time, each outstanding share of Finisar Common Stock (other than Dissenting Stockholder Shares and Excluded Shares) will be converted into the right to receive, at the election of the holder of such share of Finisar Common Stock, (i) Cash Election Consideration, consisting of $26.00 in cash, without interest (subject to the proration adjustment procedures described in this joint proxy statement/prospectus), (ii) Stock Election Consideration, consisting of 0.5546 validly issued, fully paid andnon-assessable shares ofII-VI Common Stock (subject to the proration adjustment procedures described in this joint proxy statement/prospectus), or (iii) Mixed Election Consideration, consisting of $15.60 in cash, without interest, and 0.2218 validly issued, fully paid andnon-assessable shares ofII-VI Common Stock; provided, that Finisar stockholders who are otherwise entitled to receive fractional shares ofII-VI Common Stock as part of the Merger Consideration will receive cash in lieu of such fractional shares ofII-VI Common Stock.

Each holder of record of shares of Finisar Common Stock (not including the Dissenting Stockholder Shares or the Excluded Shares, but including holders of Participating RSUs) will, until the Election Deadline, be entitled to elect to receive either Cash Election Consideration, Stock Election Consideration or Mixed Election Consideration in exchange for each share of Finisar Common Stock held by him or her that was issued and outstanding immediately prior to the Effective Time (including with respect to such holder’s Participating RSUs held by such holder prior to the Effective Time), subject to the proration adjustment procedures described in this joint proxy statement/prospectus. Holders entitled to make an election that fail to do so or that make an untimely election (or who otherwise are deemed not to have submitted an effective form of election) will be deemed to have elected for Mixed Election Consideration.

Elections to receive Cash Election Consideration (each, a “Cash Election”) and elections to receive Stock Election Consideration (each, a “Stock Election”) are subject to the proration adjustment procedures set forth in the Merger Agreement to ensure that the aggregate Merger Consideration will consist of approximately 60% cash and approximately 40%II-VI Common Stock (with theII-VI Common Stock valued at the closing price as of November 8, 2018).

Based on the number of shares of Finisar Common Stock outstanding as of                , 2019, and the treatment of shares of Finisar Common Stock, Finisar Stock Options and Finisar Restricted Stock Units in the Merger, and assuming no conversions of the Finisar Convertible Notes,II-VI expects to issue approximately                million shares ofII-VI Common Stock to holders of Finisar Common Stock and Finisar equity awards upon completion of the Merger. The actual number of shares ofII-VI Common Stock to be issued upon completion of the Merger will be determined at the completion of the Merger based on, among other things, the number of shares of Finisar Common Stock outstanding and the market price ofII-VI Common Stock at that time. Based on the number of shares of Finisar Common Stock outstanding as of                , 2019, and the number of shares ofII-VI Common Stock outstanding as of                , 2019, it is expected that, immediately after completion of the Merger, former holders of Finisar Common Stock and Finisar equity awards will own approximately     % of the outstanding shares ofII-VI Common Stock.

Background of the Merger

Each of the Finisar Board and theII-VI Board, together with their respective management teams (which we refer to as Finisar management andII-VI management), regularly reviews and assesses their respective company’s performance, future growth prospects, business strategies and opportunities and challenges as part of their evaluation of their company’s prospects and strategies for enhancing long-term shareholder value. As part of that review process, each of the boards and management teams have regularly reviewed and considered their company’s respective strategic direction and business objectives, including strategic opportunities that might be available to them, such as possible acquisitions, divestitures and business combination transactions.

The Merger and the terms of the Merger Agreement are the result of arm’s length negotiations conducted between representatives ofII-VI, Finisar and their respective legal and financial advisors. The following is a summary of the principal events, meetings, negotiations and actions among the parties leading to the execution and public announcement of the Merger Agreement.

In connection withII-VI’s regular review process mentioned above, during the course of 2017II-VI management identified Finisar to theII-VI Board as one of the companies that had products and technologies that were complementary to those ofII-VI and which potentially could represent an opportunity forII-VI to rapidly accelerate its growth into new markets that will require new capabilities and potentially reduce costs. In particular,II-VI management was of the view that a combination with Finisar could offer unique additional opportunities in 5G with the InP platform and switching products, 3D sensing, and LiDAR, and create an overall larger and more diversified platform for accelerated growth in optoelectronics, compound semiconductors, and engineered materials for the rapidly evolving datacom/telecommunications, sensing, and power electronics markets.

Such results included a 20% year over year increase in Revenues, a 25% year over year increase in Operating Income and a 25% year over year increase in GAAP EPS. The II-VI closing share price on November 1 was $44.56, representing a 19.7% increase from theII-VI closing share price on October 31.

On November 2, 2018, representatives of BofA Merrill Lynch, on behalf ofII-VI, relayed to Barclays the views of theII-VI Board as it related to the October 31 Response.

On November 2, 2018, representatives of Finisar,II-VI, O’Melveny and K&L Gates held discussions regarding key points in the draft merger agreement.

On November 3, 2018, the Finisar Board held a telephonic special meeting. Also present were representatives of Barclays and O’Melveny. Mr. Hurlston informed the Finisar Board thatII-VI had accepted the Exchange Ratio Proposal and updated the Finisar Board on next steps and timing for signing the merger agreement. Discussion by the Finisar Board ensued. Representatives of Barclays then summarized the Exchange Ratio Proposal again for the Finisar Board and discussed the scenario where the collar set forth in the Exchange Ratio Proposal would be nullified if the closing share price ofII-VI Common Stock immediately prior to the execution of the merger agreement exceeded the deemed share price ofII-VI Common Stock such that the Finisar securityholders receiving merger consideration would own approximately 30% of the outstanding shares ofII-VI Common Stock on a pro forma basis after giving effect to the expected vesting of certain Finisar Restricted Stock Units prior to the expected effective time of the merger (the “Nullified Scenario”), which would obviate the need for the Exchange Ratio Proposal. Representatives of Barclays discussed that if the Nullified Scenario occurred, the exchange ratio for the stock consideration would be determined using the last closing price of theII-VI Common Stock prior to signing the merger agreement. Discussion by the Finisar Board ensued. Mr. Brown and representatives of O’Melveny reviewed with the Finisar Board the major open issues in the merger agreement andII-VI’s positions relating thereto. Discussion by the Finisar Board ensued. After discussion, the Finisar Board instructed O’Melveny to continue to negotiate the terms of the merger agreement with K&L Gates. The Finisar Board then reviewed a due diligence report prepared onII-VI from Mr. Young on operations ofII-VI and a due diligence report from Mr. Adzema on certain accounting matters. Representatives of Barclays reviewedII-VI’s recent earnings announcement and related equity analysts call. Mr. Adzema noted for the Finisar Board that BDO USA, LLP had been engaged to assist with due diligence onII-VI (which engagement did not include a contingent or success fee).

On November 5 and 6, 2018, representatives of Finisar and O’Melveny and representatives ofII-VI and K&L Gates met in person to discuss and negotiate the terms of the merger agreement. The discussions included, among other things, the right of theII-VI Board to change its recommendation of the merger to theII-VI shareholders if there was an intervening event such that the fiduciary duties of theII-VI Board obligated it to

93

make that change in recommendation, for which it could be required by Finisar to pay a termination fee, certain deal protection provisions, Finisar’s obligations to cooperate withII-VI in connection withII-VI’s debt financing, and regulatory matters.

94

on behalf of Finisar andII-VI, respectively, and discussed and agreed that the Nullified Scenario had occurred and that the exchange ratio for the stock consideration would be fixed in the Merger Agreement using the closing share price ofII-VI Common Stock as of November 8, 2018. Representatives of Finisar andII-VI participated in certain of those discussions.

Later on November 8, 2018, the Finisar Board held a telephonic special meeting to consider the terms of the final proposed business combination withII-VI and the terms of the Merger Agreement.

At the request of the Finisar Board, a representative of Barclays then delivered its oral opinion, which was subsequently confirmed in writing, to the effect that, based upon and subject to the assumptions and limitations described in the opinion, as of the date of the opinion, from a financial point of view, the merger consideration to be offered to the stockholders of Finisar, other than holders of Excluded Shares (as defined in the Merger Agreement) was fair, from a financial point of view, to such stockholders. Representatives of O’Melveny again reviewed with the Finisar Board its fiduciary duties with respect to the potential sale of Finisar, the material terms of the draft merger agreement and the proposed amendment to Finisar’s amended and restated bylaws to provide for Delaware as its exclusive forum for certain litigation involving Finisar. After discussion among the directors, the Finisar Board unanimously voted to, among other things (i) approve and declare advisable the Merger Agreement and the other transactions contemplated thereby, including the Merger, (ii) determine that the terms of the Merger Agreement, the Merger and the other transactions contemplated thereby are fair to and in the best interests of Finisar and its stockholders and (iii) recommend that the holders of the Finisar Common Stock adopt the Merger Agreement, and instructed Finisar management to sign and deliver the Merger Agreement on behalf of Finisar.

Separately on the evening of November 8, 2018, theII-VI Board held a regular,in-person meeting. Also present and participating were representatives of BofA Merrill Lynch and K&L Gates. At the meeting, representatives of BofA Merrill Lynch provided an overview of the final materials terms of the proposed debt financing for the transaction.

Certain Relationships between Finisar andII-VI

Finisar,II-VI and their respective affiliates engage in transactions and enter into agreements with each other in the ordinary course of business, including certain agreements pursuant to which(i) II-VI supplies Finisar with various micro-optics, including filters, lenses and mirrors,(ii) II-VI, through its EpiWorks subsidiary, supplies Finisar with epitaxial wafers, and (iii) Finisar suppliesII-VI with Datacom network products. Except as described in this joint proxy statement/prospectus, there are and have been no past, present or proposed material contracts, arrangements, understandings, relationships, negotiations or transactions during the current calendar year or the five immediately preceding calendar years, between Finisar or its affiliates, on the one hand, andII-VI or its affiliates, on the other hand, concerning a merger, consolidation or acquisition, a tender offer for or other acquisition of securities, the election of directors, or the sale or other transfer of a material amount of assets.

Finisar’s Reasons for the Merger; Recommendations of the Finisar Board

In reaching its decision to approve and declare advisable the Merger Agreement and the transactions contemplated thereby, including the Merger, to determine that the terms of the Merger Agreement, the Merger and the other transactions contemplated thereby are fair to and in the best interests of Finisar and its stockholders, and to recommend that Finisar’s stockholders vote “FOR” the approval of the Merger Proposal, the Finisar Board consulted with Finisar’s management and legal and financial advisors and considered a variety of factors, including the following (which are not necessarily in order of relative importance):

• historical information regarding (i) Finisar’s business, financial performance and results of operations, (ii) market prices, volatility and trading activity with respect to Finisar Common Stock, and (iii) market prices with respect to other industry participants and general market indices;

• current information regarding (i) Finisar’s business, prospects, financial condition, operations, technology, products, services, management, competitive position and strategic business goals and objectives, (ii) general economic, industry and financial market conditions, and (iii) opportunities and competitive factors within Finisar’s industry, and the challenges of projecting Finisar’s financial performance in the long term, including fiscal year 2021 and beyond;

• historical information regardingII-VI’s business and financial performance and market prices ofII-VI Common Stock;

• the prospects and likelihood of realizing superior benefits through remaining an independent company, risks associated with remaining an independent company, and possible alternative business strategies;

• the belief of the Finisar Board that continuing attempts to engage with other possible strategic partners was unlikely to result in a transaction at a more attractive price than offered byII-VI in the Merger, as well as the potential for other third parties to enter into strategic relationships with or to seek to acquire Finisar, including a review of management’s dealings with other possible buyers in the past, efforts by representatives of Finisar’s financial advisor, at the direction of Finisar, to engage other potential acquirers of Finisar regarding a strategic transaction, and the likelihood that a third party would offer a higher price than the price per share offered byII-VI and the likelihood that any stock consideration offered by another bidder would be as attractive as the stock consideration being offered byII-VI;

• the timing of the Merger and the risk that if Finisar does not accept theII-VI offer now (as provided for in the Merger Agreement), it may not have another opportunity to do so or a comparable opportunity;

• the fact that both the Stock Election Consideration and the Cash Election Consideration will be taxable;

• the fact that Finisar would be permitted, under circumstances described in the Merger Agreement, to terminate the Merger Agreement in order to enter into an agreement with respect to a superior proposal to acquire Finisar after givingII-VI the opportunity to match the superior proposal and upon payment of a termination fee equal to 3.25% of the equity value of Finisar (based on the purchase price agreed to in the Merger Agreement);

96

• the fact that, under the terms of the Merger Agreement,II-VI has agreed to use its reasonable best efforts to take, or cause to be taken, all things necessary, proper or advisable under applicable law (including making filings pursuant to applicable antitrust laws) to consummate the Merger Agreement and the transactions contemplated thereby as promptly as practicable, including obtaining necessary regulatory approvals in China;

• the belief of the Finisar Board that an acquisition byII-VI has a reasonable likelihood of closing without material potential issues under applicable antitrust laws or material potential issues from any governmental authorities;

• (i) the financial analyses presented by representatives of Finisar’s financial advisor to the Finisar Board based on projections provided by Finisar’s management and (ii) the opinion of the financial advisor that, as of the date thereof, from a financial point of view, the Merger Consideration to be offered to the stockholders of Finisar (other than the holders of Excluded Shares (as defined in the Merger Agreement)) in the Merger is fair to such stockholders;

• the fact that Finisar will no longer exist as an independent public company and Finisar’s stockholders will forgo any future increase in its value as an independent public company that might result from its possible growth (together with the possibility of near and long-term fluctuations in the value ofII-VI Common Stock to be issued in the Merger);

• the possible negative effect of the Merger and public announcement of the Merger on Finisar’s financial performance, operating results and stock price and Finisar’s relationships with customers, suppliers, other business partners, management and employees;

• the possible negative effect of the Merger and public announcement of the Merger onII-VI’s financial performance, operating results and stock price andII-VI’s relationships with customers, suppliers, other business partners, management and employees;

• the fact that the Merger Agreement (i) precludes Finisar from actively soliciting competing acquisition proposals and (ii) obligates Finisar (or its successor) to payII-VI a termination fee equal to 3.25% of the equity value of Finisar (based on the purchase price agreed to in the Merger Agreement) under specified circumstances;

• the fact that the Merger Agreement obligatesII-VI to pay Finisar a termination fee equal to 3.25% of the equity value of Finisar (based on the purchase price agreed to in the Merger Agreement) under specified circumstances;

• the fact that the Merger Agreement imposes restrictions on the conduct of Finisar’s business in thepre-closing period, which may adversely affect Finisar’s business in the event the Merger is not completed (including by delaying or preventing Finisar from pursuing strategic business opportunities that may arise or precluding actions that would be advisable if Finisar were to remain an independent company), and which may significantly restrict the operation of Finisar’s business;

• the fact that(i) II-VI is financing the cash portion of the aggregate Merger Consideration in part through debt financing and, concurrently with the execution of the Merger Agreement, delivered the Commitment Letter, and(ii) II-VI has agreed to use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary to arrange, obtain and consummate the debt financing;

• the risks involved with the Merger and the likelihood that Finisar andII-VI will be able to complete the Merger, the possibility that the Merger might not be consummated and Finisar’s prospects going forward without the combination withII-VI;

• the substantial transaction expenses to be incurred in connection with the Merger and the negative impact of such expenses on Finisar’s cash reserves and operating results should the Merger not be completed;

97

• all known interests of directors and executive officers of Finisar in the Merger that may be different from, or in addition to, their interests as stockholders of Finisar or the interests of Finisar’s other stockholders generally;

• the limited availability of appraisal rights to stockholders of Finisar in connection with the Merger; and

• all other factors the Finisar Board deemed relevant.

The above discussion of the material factors considered by Finisar’s Board in its consideration of the Merger and the other transactions contemplated by the Merger Agreement is not intended to be exhaustive, but does set forth the principal factors considered by the Finisar Board. The Finisar Board viewed its decision as based on all of the information available to it and the factors presented to and considered by it, including its experience and history. In addition, individual directors may themselves have given different weight to different factors. The factors, potential risks and uncertainties contained in this explanation of Finisar’s reasons for the Merger and other information presented in this section contain information that is forward-looking in nature and, therefore, should be read in light of the factors discussed in “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 62 of this joint proxy statement/prospectus.

ACCORDINGLY, THE FINISAR BOARD UNANIMOUSLY RECOMMENDS THAT FINISAR STOCKHOLDERS VOTE “FOR” THE MERGER PROPOSAL, “FOR” THE FINISAR ADJOURNMENT PROPOSAL, IF NECESSARY OR APPROPRIATE, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE INSUFFICIENT VOTES AT THE TIME OF THE SPECIAL MEETING TO APPROVE THE MERGER PROPOSAL, AND “FOR” THE COMPENSATION PROPOSAL.

II-VI’s Reasons for the Merger; Recommendations of theII-VI Board

In evaluating the Merger Agreement and the Merger, theII-VI Board consulted withII-VI’s management and legal and financial advisors and, in reaching its decision to approve the Merger Agreement and the transactions contemplated by the Merger Agreement, including the stock issuance, and to recommend thatII-VI’s shareholders vote “FOR” the approval of the Stock Issuance Proposal, theII-VI Board considered a variety of factors, including the following (which are not necessarily in order of relative importance):

Strategic Factors

The acquisition of Finisar and the combination of Finisar’s businesses withII-VI’s businesses is expected to result in a number of strategic benefits, including:

• creating one of the largest and scalable photonics and compound semiconductor companies, which should accelerate revenue growth;

• providing the company with a robust monolithic tunable InP platform that is used in many optical communications components, including datacom transceivers, products based on coherent transmissions technology and ROADM solutions, which products will be marketable into next-generation long-haul and metro networks, hyperscale datacenters, and 5G mobile infrastructure;

• creating a compelling platform for 3D sensing and LiDAR products because the combined optoelectronics technology leadership based on GaAs and InP compound semiconductor laser design platforms, together with one of the world’s largest6-inch vertically integrated epitaxial growth and device fabrication platforms, should enable faster time to market with new products to address a greater number of opportunities in the growing consumer 3D sensing and automotive LiDAR markets;

• providing access to larger addressable markets because of the broad portfolio of differentiated products based on engineered materials, including GaAs, InP, SiC, GaN, and diamond, together with a critical mass of optoelectronic, optical and integrated circuit device design expertise, and related intellectual property, which are becoming increasingly important with respect to RF devices for next-generation

98

wireless and military applications, power electronics for electric and autonomous vehicles and green energy infrastructure, and other next-generation sensor modules that will be incorporated into the internet of things;

• maximizing value creation through increased vertical integration of core technologies ranging from engineered materials to highvalue-add solutions, enabled by differentiated components, which should provide a strong foundation to capitalize on a broad range of emerging opportunities while making the overall markets for these products even more competitive;

• optimizing time to market, volume, and cost because the combined scale and expertise should enhance speed and certainty of success across large and irreversible mega-trend market opportunities;

• increasing diversification by combining a large, scaled communications business and a diversified industrial laser and component maker to create leadership across multipleend-markets, including Datacom/telecom, lasers, 3D sensing, power electronics, and EUV lithography;

• becoming a leader in the market for both high-power andlow-power VCSELs by combining complementary expertise and capabilities in order to fill needed capacity and competitive roadmaps in the markets for those products;

• creating a much more substantial financial and operational base to support more significant acquisitions in a rapidly developing product and technology market;

• providing annual estimated synergies of approximately $150 million within 36 months of the completion of the Merger, and the potential for long-term opportunities for additional savings, due to expected procurement savings, the savings associated with the internal supply of materials and components, efficient research and development, consolidation of overlapping costs, and sales and marketing efficiencies; and

• providing approximately 10% accretion inNon-GAAP earnings per share in the first full year following closing, and more than double that level of accretion thereafter.

Other Factors

In addition to the strategic factors summarized above, theII-VI Board also considered the following factors in connection with its evaluation of the Merger:

• the respective businesses, operations, management, financial condition, earnings, market reputation, competitive pressures, regulatory constraints and prospects ofII-VI and Finisar;

• the results ofII-VI’s due diligence investigation of Finisar and the reputation, business practices and experience of Finisar and its management;

• the historical trading prices of shares ofII-VI Common Stock and Finisar Common Stock;

• the review by theII-VI Board, in consultation with its legal, financial and other advisors, of the structure of the Merger and the financial and other terms of the Merger Agreement;

• trends and competitive developments in the industries in whichII-VI and Finisar operate;

• the fact that the issuance ofII-VI Common Stock as Merger Consideration will be subject to the approval ofII-VI’s shareholders;

• the range of other strategic alternatives available toII-VI and theII-VI Board’s belief that the transaction with Finisar presented a more favorable opportunity forII-VI’s shareholders than the potential value that may result from other strategic alternatives available toII-VI;

• the fact that theII-VI Board had carefully considered, after consulting withII-VI’s management and financial, legal and other advisors, the potential consequences forII-VI if Finisar were to pursue certain strategic alternatives to the proposed transaction withII-VI, and theII-VI Board’s belief thatII-VI’s strategic alternatives may be more limited and less favorable in such circumstances;

99

Price and Structure

• the fact that, because the exchange ratios for the shares ofII-VI Common Stock that will be issued in the Merger as part of the Stock Election Consideration and the Mixed Election Consideration are fixed (and will not be adjusted for fluctuations in the market price of shares ofII-VI Common Stock or Finisar Common Stock),II-VI has greater certainty as to the number of shares ofII-VI Common Stock to be issued in the Merger;

• taking into account the report theII-VI Board had received regarding past fees received by BofA Merrill Lynch for services provided toII-VI and Finisar, and the fees payable to BofA Merrill Lynch in connection with the transactions contemplated by the Merger Agreement and the related financing transactions, the financial analysis of BofA Merrill Lynch and the opinion of BofA Merrill Lynch, dated November 8, 2018, to theII-VI Board as to the fairness, from a financial point of view and as of the date of the opinion, toII-VI of the Merger Consideration to be paid byII-VI in the Merger, as more fully described below in the section entitled “The Merger — Opinion ofII-VI’s Financial Advisor” beginning on page 112 of this joint proxy statement/prospectus;

Certain Other Factors

• the belief of theII-VI Board, following consultation withII-VI’ management, and based in part upon the debt financing commitments thatII-VI obtained, thatII-VI will have the necessary financing to pay the aggregate cash portion of the Merger Consideration and thatII-VI, following the Merger, will be able to repay, service or refinance any indebtedness that is expected to form the financing for the Merger and, with respect to such indebtedness, to comply with applicable financial covenants;

• the belief of theII-VI Board, following consultation withII-VI’s management, that the financing commitments it had obtained to finance the aggregate cash portion of the aggregate Merger Consideration were on attractive terms forII-VI;

• the belief of theII-VI Board thatII-VI would have an investment grade credit rating after incurring the indebtedness necessary to finance the cash portion of the aggregate Merger Consideration;

• the experience ofII-VI’s management in integrating acquired companies;

• the expectation that members of Finisar’s management team will play significant roles in the combined company;

• the fact that Dr. Vincent D. Mattera, Jr.,II-VI’s President and Chief Executive Officer, will continue to lead the combined company;

• the ability of theII-VI Board, subject to certain conditions, to change its recommendation thatII-VI shareholders adopt the Stock Issuance Proposal in response to certain intervening events, if theII-VI Board determines that failure to take such action would be reasonably likely to constitute a breach of its fiduciary duties;

• the limited ability of the Finisar Board to change its recommendation that Finisar stockholders approve and adopt the Merger Agreement;

• the fact that Finisar is required to payII-VI a termination fee of $105.2 million if the Merger Agreement is terminated under certain circumstances; and

• the fact that the end date under the Merger Agreement of November 8, 2019 allows for sufficient time to complete the Merger.

TheII-VI Board also considered a number of uncertainties and risks in its deliberations concerning the Merger, including the following:

• the fact that the exchange ratios will not change as a result of fluctuations in the market value ofII-VI Common Stock, which could result inII-VI delivering greater value to Finisar stockholders should the

100

value of the shares ofII-VI Common Stock increase between the execution of the Merger Agreement and the Effective Time;

• the fact that the opinion of BofA Merrill Lynch to theII-VI Board as to the fairness, from a financial point of view, of the Merger Consideration to be paid byII-VI in the Merger speaks only as of the date of the opinion and will not take into account events occurring or information that has become available after such date, including any changes in the operations and prospects ofII-VI and Finisar, general market and economic conditions and other factors which may be beyond the control ofII-VI and Finisar and on which the fairness opinion was based, any of which may be material;

• the risk that the Merger may not be completed or may be delayed despite the parties’ efforts, including the possibility that conditions to the parties’ obligations to complete the Merger may not be satisfied, and the potential resulting disruptions toII-VI’s and Finisar’s businesses;

• the potential length of the regulatory approval process and the period of time during whichII-VI may be subject to certain restrictions on the conduct of its businesses, which could preventII-VI from making certain acquisitions or divestitures or otherwise pursuing certain business opportunities;

• the possibility that governmental authorities might seek to require certain actions ofII-VI or Finisar or impose certain terms, conditions or limitations onII-VI’ or Finisar’s businesses in connection with granting approval of the Merger or might otherwise seek to prevent or delay the Merger;

• the fact thatII-VI is required to pay Finisar a termination fee of $105.2 million if the Merger Agreement is terminated under certain circumstances;

• the fact thatII-VI has incurred and will continue to incur significant transaction and integration planning fees and expenses in connection with the Merger, regardless of whether it is completed;

• the challenges inherent in the combination of two businesses of the size, scope and complexity ofII-VI and Finisar, including the potential for unforeseen difficulties in integrating operations and systems and difficulties and costs of integrating or retaining employees;

• the risk that the potential benefits of the Merger may not be fully realized, including the possibility that expected synergies, cost savings and operating efficiencies expected to result from the Merger may not be realized to the extent expected, or at all;

• the risk of divertingII-VI management focus and resources from other strategic opportunities and operational matters, and potential disruption ofII-VI management associated with the Merger and integrating the companies;

• Finisar’s ability, under circumstances described in the Merger Agreement, to provide information to and engage in discussions or negotiations with a third party that makes an unsolicited bona fide written takeover proposal;

• the ability of the Finisar Board, subject to certain conditions, to change its recommendation supporting the Merger in response to a superior proposal or an intervening event other than a superior proposal, if the Finisar Board determines that failure to take such action would be reasonably likely to constitute a breach of its fiduciary duties;

• the ability of the Finisar Board, subject to certain conditions, to terminate the Merger Agreement in order to enter into a definitive agreement providing for a superior proposal;

• the absence of a financing condition in the Merger Agreement and Finisar’s ability to seek specific enforcement ofII-VI’s obligations under the Merger Agreement whether or notII-VI is able to maintain its committed financing for the acquisition;

• the fact thatII-VI will have higher leverage following the transactions due to the debt financing commitments thatII-VI has obtained, which could have adverse consequences toII-VI’s business and financial position or its ability to pursue acquisition opportunities following the Merger;

101

• the potential negative effects of the announcement and pendency of the Merger onII-VI’s and Finisar’s businesses, including stockholder and market reactions and relationships with employees, customers, vendors, regulators and the communities in which they operate, including the risk that certain key members of senior management ofII-VI or Finisar might not choose to remain with the combined company;

• the dilution of existing shares ofII-VI Common Stock associated with the stock issuance;

• the risk that theII-VI shareholders do not approve the Stock Issuance Proposal or the Finisar stockholders do not approve the Merger Proposal, each of which is a condition to completion of the Merger;

• the risk of litigation related to the transaction; and

• various other risks associated with the Merger and the businesses ofII-VI, Finisar and the combined company described under “Risk Factors,” beginning on page 48 and the matters described under “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 62 of this joint proxy statement/prospectus.

During its consideration of the Merger, theII-VI Board was also aware that certain of Finisar’s directors and executive officers may have interests in the Merger that are different from or in addition to those of Finisar stockholders generally, as described in the section entitled “Interests of Finisar’s Directors and Executive Officers in the Merger” beginning on page 166 of this joint proxy statement/prospectus.

The above discussion of the material factors considered by theII-VI Board in its consideration of the Merger and the other transactions contemplated by the Merger Agreement is not intended to be exhaustive, but does set forth the principal factors considered by theII-VI Board. In light of the number and wide variety of factors considered in connection with the evaluation of the Merger, theII-VI Board did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors it considered in reaching its final decision. TheII-VI Board viewed its position as being based on all of the information available to it and the factors presented to and considered by it. However, some directors may themselves have given different weight to different factors. The factors, potential risks and uncertainties contained in this explanation ofII-VI’s reasons for the Merger and other information presented in this section contain information that is forward-looking in nature and, therefore, should be read in light of the factors discussed in “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 62 of this joint proxy statement/prospectus.

ACCORDINGLY, THEII-VI BOARD UNANIMOUSLY RECOMMENDS THATII-VI SHAREHOLDERS VOTE “FOR” THE SHARE ISSUANCE PROPOSAL AND “FOR” THEII-VI ADJOURNMENT PROPOSAL, IF NECESSARY OR APPROPRIATE, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE INSUFFICIENT VOTES AT THE TIME OF THE SPECIAL MEETING TO APPROVE THE SHARE ISSUANCE.

Opinion of Finisar’s Financial Advisor

Finisar engaged Barclays for the purpose of providing financial advisory services with respect to a potential sale of Finisar, pursuant to an engagement letter dated October 12, 2018. On November 8, 2018, Barclays rendered its oral opinion (which was subsequently confirmed in writing) to the Finisar Board that, as of such date and based upon and subject to the qualifications, limitations and assumptions stated in its opinion, the Merger Consideration to be offered to the stockholders of Finisar, other than holders of Excluded Shares (as defined in the Merger Agreement), was fair, from a financial point of view, to such stockholders.

The full text of Barclays’ written opinion, dated as of November 8, 2018, is attached asAnnex C to this joint proxy statement/prospectus. Barclays’ written opinion sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by

102

Barclays in rendering its opinion. You are encouraged to read the opinion carefully in its entirety. The following is a summary of Barclays’ opinion and the methodology that Barclays used to render its opinion. This summary is qualified in its entirety by reference to the full text of the opinion.

Barclays’ opinion, the issuance of which was approved by Barclays’ Valuation and Fairness Opinion Committee, is addressed to the Finisar Board, addresses only the fairness, from a financial point of view, of the Merger Consideration to be offered to the stockholders of Finisar, other than holders of Excluded Shares (as defined in the Merger Agreement), in the proposed transaction and does not constitute a recommendation to any stockholder of Finisar as to how such stockholder should vote or act with respect to the proposed transaction or any other matter. The terms of the proposed transaction were determined througharm’s-length negotiations between Finisar andII-VI and were unanimously approved by the Finisar Board. Barclays did not recommend any specific form of consideration to Finisar or that any specific form of consideration constituted the only appropriate consideration for the proposed transaction. Barclays was not requested to opine as to, and its opinion does not in any manner address, Finisar’s underlying business decision to proceed with or effect the proposed transaction or the likelihood of the consummation of the proposed transaction. In addition, Barclays expressed no opinion on, and its opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the Merger Consideration to be offered to the stockholders of Finisar in the proposed transaction. Barclays’ opinion does not address the relative merits of the proposed transaction as compared to any other transaction or business strategy in which Finisar may engage. No limitations were imposed by the Finisar Board upon Barclays with respect to the investigations made or procedures followed by it in rendering its opinion.

In arriving at its opinion, Barclays, among other things:

• reviewed and analyzed the Merger Agreement and the specific terms of the proposed transaction;

• reviewed and analyzed publicly available information concerning Finisar that Barclays believed to be relevant to its analysis, including Finisar’s Annual Report on Form10-K for the fiscal year ended April 29, 2018 and its Quarterly Report on Form10-Q for the fiscal quarter ended July 29, 2018;

• reviewed and analyzed publicly available information concerningII-VI that Barclays believed to be relevant to its analysis, includingII-VI’s Annual Report on Form10-K for the fiscal year ended June 30, 2018 and its Quarterly Report on Form10-Q for the fiscal quarter ended September 30, 2018;

• reviewed and analyzed financial and operating information with respect to the business, operations and prospects of Finisar furnished to Barclays by Finisar, including financial projections of Finisar prepared by Finisar’s management (the “Finisar Projections”);

• reviewed and analyzed the Barclays Fairness Opinion II-VI projections (as defined below);

• reviewed and analyzed published estimates of independent research analysts with respect to the future financial performance of Finisar andII-VI;

• reviewed and analyzed a trading history of the shares of Finisar Common Stock from November 8, 2013 through November 8, 2018;

• reviewed and analyzed a trading history of the shares ofII-VI Common Stock from November 8, 2013 through November 8, 2018;

• reviewed and analyzed a comparison of the historical financial results and present financial condition of Finisar andII-VI with those of other companies that Barclays deemed relevant;

• reviewed and analyzed the pro forma impact of the proposed transaction on the future financial performance of the combined company, including cost savings, operating synergies, and other strategic benefits, expected by the management of the Finisar to result from a combination of the businesses (the “Expected Synergies”);

• reviewed and analyzed a comparison of the financial terms of the proposed transaction with the financial terms of certain other transactions that Barclays deemed relevant;

103

• had discussions with the management of Finisar and the management ofII-VI concerningII-VI’s business, operations, assets, liabilities, financial condition and prospects;

• had discussions with the management of Finisar concerning Finisar’s business, operations, assets, liabilities, financial condition and prospects; and

• has undertaken such other studies, analyses and investigations as Barclays deemed appropriate.

In arriving at its opinion, Barclays assumed and relied upon the accuracy and completeness of the financial and other information used by Barclays without any independent verification of such information (and had not assumed responsibility or liability for any independent verification of such information). Barclays also relied upon the assurances of management of Finisar and the management ofII-VI that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Finisar Projections, upon advice of Finisar, Barclays assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Finisar as to Finisar’s future financial performance. With respect to the Barclays Fairness Opinion II-VI projections, Barclays assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of II-VI as to the future financial performance ofII-VI. Furthermore, upon the advice of Finisar, Barclays assumed that the amounts and timing of the Expected Synergies were reasonable and that the Expected Synergies would be realized in accordance with such estimates. In arriving at its opinion, Barclays assumed no responsibility for and expressed no view as to any such projections or estimates or the assumptions on which they were based. In arriving at its opinion, Barclays did not conduct a physical inspection of the properties and facilities of Finisar orII-VI and did not make or obtain any evaluations or appraisals of the assets or liabilities of Finisar orII-VI. Barclays’ opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, November 8, 2018. Barclays assumed no responsibility for updating or revising its opinion based on events or circumstances that may have occurred after November 8, 2018. Barclays expressed no opinion as to the prices at which shares of Finisar Common Stock or shares ofII-VI Common Stock would trade following the announcement of the proposed transaction or as to the prices at which shares ofII-VI Common Stock would trade following the consummation of the proposed transaction. Barclays’ opinion should not be viewed as providing any assurance that the market value of the shares ofII-VI Common Stock to be held by the stockholders of Finisar after the consummation of the proposed transaction will be in excess of the market value of the shares of Finisar Common Stock owned by such stockholders at any time prior to the announcement or consummation of the proposed transaction.

Barclays assumed the accuracy of the representations and warranties contained in the Merger Agreement and all the agreements related thereto. Barclays also assumed, upon the advice of Finisar, that all material governmental, regulatory and third party approvals, consents and releases for the proposed transaction would be obtained within the constraints contemplated by the Merger Agreement and that the proposed transaction will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any material term, condition or agreement thereof. Barclays did not express any opinion as to any tax or other consequences that might result from the proposed transaction, nor did Barclays’ opinion address any legal, tax, regulatory or accounting matters, as to which Barclays understood Finisar had obtained such advice as it deemed necessary from qualified professionals.

In connection with rendering its opinion, Barclays performed certain financial, comparative and other analyses as summarized below. In arriving at its opinion, Barclays did not ascribe a specific range of values to the shares of Finisar Common Stock but rather made its determination as to fairness, from a financial point of view, to Finisar’s stockholders (other than holders of Excluded Shares (as defined in the Merger Agreement)) of the Merger Consideration to be offered to such stockholders in the proposed transaction on the basis of various financial and comparative analyses. The preparation of a fairness opinion is a complex process and involves various determinations as to the most appropriate and relevant methods of financial and comparative analyses and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to summary description.

104

In arriving at its opinion, Barclays did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor relative to all other analyses and factors performed and considered by it and in the context of the circumstances of the particular transaction. Accordingly, Barclays believes that its analyses must be considered as a whole, as considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion.

Summary of Material Financial Analyses

The following is a summary of the material financial analyses used by Barclays in preparing its opinion to the Finisar Board. The summary of Barclays’ analyses and reviews provided below is not a complete description of the analyses and reviews underlying Barclays’ opinion. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant methods of analysis and review and the application of those methods to particular circumstances, and, therefore, is not readily susceptible to summary description.

For the purposes of its analyses and reviews, Barclays made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Finisar or any other parties to the proposed transaction. No company, business or transaction considered in Barclays’ analyses and reviews is identical to Finisar,II-VI, Merger Sub or the proposed transaction, and an evaluation of the results of those analyses and reviews is not entirely mathematical. Rather, the analyses and reviews involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, businesses or transactions considered in Barclays’ analyses and reviews. None of Finisar,II-VI, Merger Sub, Barclays or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses and reviews and the ranges of valuations resulting from any particular analysis or review are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth below. In addition, analyses relating to the value of companies, businesses or securities do not purport to be appraisals or reflect the prices at which the companies, businesses or securities may actually be sold. Accordingly, the estimates used in, and the results derived from, Barclays’ analyses and reviews are inherently subject to substantial uncertainty.

The summary of the financial analyses and reviews summarized below include information presented in tabular format. In order to fully understand the financial analyses and reviews used by Barclays, the tables must be read together with the text of each summary, as the tables alone do not constitute a complete description of the financial analyses and reviews. Considering the data in the tables below without considering the full description of the analyses and reviews, including the methodologies and assumptions underlying the analyses and reviews, could create a misleading or incomplete view of Barclays’ analyses and reviews.

Selected Comparable Company Analysis for Finisar

In order to assess how the public market values shares of similar publicly traded companies and to provide a range of relative implied equity values per share of Finisar by reference to those companies, Barclays reviewed and compared specific financial and operating data relating to Finisar with selected companies that Barclays, based on its experience in the optical components industry, deemed comparable to Finisar. The selected comparable companies with respect to Finisar were:

Acacia Communications, Inc.

Applied Optoelectronics, Inc.

Lumentum Holdings, Inc.

NeoPhotonics Corporation

II-VI Incorporated

105

Barclays calculated and compared various financial multiples and ratios of Finisar and the selected comparable companies. As part of its selected comparable company analysis, Barclays calculated and analyzed each company’s enterprise value, or EV, as a multiple of (i) its calendar year 2018 and 2019 estimated revenue, (ii) its calendar year 2018 and 2019 estimated earnings before interest, taxes, depreciation, amortization and stock-based compensation, or EBITDAS, which, for Acacia Communications, Inc. and NeoPhotonics Corporation, was not meaningful for calendar year 2018 due to a negative EBITDAS value or because the multiple was greater than 25.0x, and (iii) its calendar year 2018 and 2019 estimated operating income, which, for Acacia Communications, Inc. (for calendar years 2018 and 2019), Applied Optoelectronics, Inc. (for calendar year 2018) and NeoPhotonics Corporation (for calendar years 2018 and 2019), was not meaningful because the multiple was greater than 25.0x. Barclays also calculated and analyzed each company’s ratio of its current stock price to its estimated calendar year 2018 and 2019non-GAAP earnings per share, or EPS (commonly referred to as a price earnings ratio, or P/E), which, for Acacia Communications, Inc. (for calendar year 2018) and NeoPhotonics Corporation (for calendar years 2018 and 2019), was not meaningful because the multiple yielded was greater than 45.0x. The EV of each company was obtained by adding the principal amount of its short and long-term debt to the sum of the market value of its diluted equity value, using the treasury stock method, the value of any preferred stock (at liquidation value), the value of any pension liabilities, the value of capital leases and the book value of any minority interest, and subtracting its cash and cash equivalents. All of these calculations for the comparable companies (other than forII-VI) were performed, and based, on publicly available financial data and closing prices, as of November 8, 2018, the last trading date prior to the delivery of Barclays’ opinion. All of these calculations for Finisar were performed, and based on, the Finisar Projections. All of the calculations forII-VI were performed, and based, on the Barclays Fairness OpinionII-VI projections.

Barclays selected the comparable companies listed above because of similarities in one or more business or operating characteristics with Finisar. However, because no selected comparable company is exactly the same as Finisar, Barclays believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, Barclays also made qualitative judgments concerning differences between the business, financial and operating characteristics and prospects of Finisar and the selected comparable companies that could affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between Finisar and the companies included in the selected company analysis. Based upon these judgments, Barclays selected a range of multiples for Finisar and applied such range to the Finisar Projections to calculate a range of implied prices per share of Finisar. The following table summarizes the result of these calculations:

	Low		Median		High		Selected Multiple Range		Implied Value per Share of Finisar
EV/CY 2018E Revenue		1.35x		2.54x		4.93x		1.50x – 2.00x	$	18.19 – $23.38
EV/CY 2019E Revenue		1.22x		2.22x		3.85x		1.30x – 1.80x	$	18.78 – $24.99
EV/CY 2018E Operating Income		12.6x		15.3x		18.1x		15.5x – 18.0x	$	12.05 – $13.57
EV/CY 2019E Operating Income		10.2x		11.9x		16.1x		12.5x – 14.5x	$	23.28 – $26.56
EV/CY 2018E EBITDAS		9.8x		12.7x		13.7x		10.0x – 12.0x	$	16.90 – $19.75
EV/CY 2019E EBITDAS		8.2x		9.0x		22.6x		9.0x – 12.0x	$	25.87 – $33.37
P/CY 2018ENon-GAAP EPS		13.3x		20.8x		21.0x		16.0x – 22.0x	$	11.18 – $15.38
P/CY 2019ENon-GAAP EPS		11.5x		16.3x		32.8x		14.0x – 18.0x	$	24.00 – $30.86

For purposes of its opinion, Barclays calculated the implied value, as of November 8, 2018, of the Merger Consideration to be $26.00 per Finisar share, which was determined by adding the cash portion of the Merger Consideration of $15.60 per Finisar share to $10.40, the implied value of the stock portion of the Merger Consideration per Finisar share that was derived by multiplying the closing price of $46.88 per share ofII-VI Common Stock on November 8, 2018, the last trading day prior to the announcement of the proposed transaction, by the exchange ratio of 0.2218 of a share ofII-VI Common Stock per Finisar share.

106

Barclays noted that on the basis of the selected comparable company analysis with respect to Finisar, the implied value of the Merger Consideration of $26.00 per share was (i) above the range of implied values per share of Finisar Common Stock calculated using calendar year 2018 estimated revenue, calendar year 2019 estimated revenue, calendar year 2018 estimated operating income, calendar year 2018 estimated EBITDAS and calendar year 2018 estimatednon-GAAP EPS and (ii) within the range of implied values per share of Finisar Common Stock calculated using calendar year 2019 estimated operating income, calendar year 2019 estimated EBITDAS and calendar year 2019 estimatednon-GAAP EPS.

Selected Comparable Company Analysis forII-VI

In order to assess how the public market values shares of similar publicly traded companies and to provide a range of relative implied equity values per share ofII-VI by reference to those companies, Barclays reviewed and compared specific financial and operating data relating toII-VI with selected companies that Barclays, based on its experience in the optical components industry and Industrial Lasers industry, deemed comparable toII-VI. The selected comparable companies with respect toII-VI were:

Finisar Corporation

Acacia Communications, Inc.

Lumentum Holdings, Inc.

Coherent, Inc.

IPG Photonics Corporation

MKS Instruments, Inc.

JENOPTIK AG

Barclays calculated and compared various financial multiples and ratios ofII-VI and the selected comparable companies. As part of its selected comparable company analysis, Barclays calculated and analyzed each company’s EV (calculated as described above) as a multiple of (i) its calendar year 2018 and 2019 estimated revenue and (ii) its calendar year 2018 and 2019 estimated EBITDAS, which, for Acacia Communications, Inc., was not meaningful for calendar year 2018 due to a negative EBITDAS value or because the multiple was greater than 25.0x. Barclays also calculated and analyzed each company’s ratio of its current stock price to its calendar year 2018 and 2019 estimatednon-GAAP EPS, which, for Acacia Communications, Inc., was not meaningful for calendar year 2018 because the multiple yielded was greater than 45.0x. All of these calculations for the comparable companies (other than for Finisar) were performed, and based, on publicly available financial data and closing prices, as of November 8, 2018, the last trading date prior to the delivery of Barclays’ opinion. All of these calculations for Finisar were performed, and based on, the Finisar Projections. All of the calculations forII-VI were performed, and based, on the Barclays Fairness OpinionII-VI projections.

107

Barclays selected the comparable companies listed above because of similarities in one or more business or operating characteristics withII-VI. However, because no selected comparable company is exactly the same asII-VI, Barclays believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, Barclays also made qualitative judgments concerning differences between the business, financial and operating characteristics and prospects ofII-VI and the selected comparable companies that could affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk betweenII-VI and the companies included in the selected company analysis. Based upon these judgments, Barclays selected a range of multiples forII-VI and applied such range to the Barclays Fairness OpinionII-VI projections to calculate a range of implied prices per share ofII-VI. The following table summarizes the result of these calculations:

	Low		Median		High		Selected Multiple Range		Implied Value per Share ofII-VI
EV/CY 2018E Revenue		1.57x		1.96x		4.93x		2.00x – 2.50x	$	34.41 – $43.75
EV/CY 2019E Revenue		1.31x		2.00x		4.52x		1.90x – 2.40x	$	39.67 – $50.49

Barclays noted that on the basis of the selected comparable company analysis with respect toII-VI, the closing price of $46.88 per share ofII-VI Common Stock, as of November 8, 2018, was (i) above the range of implied values per share ofII-VI Common Stock calculated using calendar year 2018 estimated revenue and calendar year 2018 estimated EBITDAS, (ii) within the range of implied values per share ofII-VI Common Stock calculated using calendar year 2019 estimated revenue, calendar year 2018 estimatednon-GAAP EPS and calendar year 2019 estimatednon-GAAP EPS and (iii) below the range of implied values per share ofII-VI Common Stock calculated using calendar year 2019 estimated EBITDAS. Shortly prior to the execution of the Merger Agreement by II-VI and Finisar, II-VI management prepared updated projections for its fiscal year 2019, which provided for $1,378.2 million of revenue, $314 million of adjusted EBITDA and $2.63 for adjusted EPS, none of which were provided to Finisar or Barclays prior to the execution of the Merger Agreement. Based on the II-VI projections (as defined below), as such projections would be adjusted in the same manner that II-VI adjusted the projections it made available to Finisar and Barclays on or prior to October 23, 2018 for FY19, which was used by Barclays in its financial analysis, for (i) revenue in calendar year 2019, the range of implied values per share of II-VI Common Stock would be $39.71 to $50.55, (ii) adjusted EBITDAS in calendar year 2019, the range of implied values per share of II-VI Common Stock would be $48.52 to $63.98, and (iii) adjusted EPS in calendar year 2019, the range of implied values per share of II-VI Common Stock would be $45.60 to $58.63. See “The Merger — Unaudited Prospective Financial Information” for more information.

Selected Precedent Transaction Analysis

Barclays reviewed and compared, where publicly available, the purchase prices and financial multiples paid in twelve selected other transactions that Barclays, based on its experience with merger and acquisition transactions, deemed relevant. Barclays chose such transactions based on, among other things, the similarity of the applicable target companies in the transactions to Finisar with respect to the size, mix, margins and other characteristics of their businesses. The selected precedent transactions were:

(1) EV/NTM Revenue, EV/LTM Operating Income, EV/NTM Operating Income and EV/NTM EBITDAS for this transaction were excluded for purposes of determining the respective selected multiple ranges and in the calculations of the low, median and high because financial information was not publicly available.

(2) EV/LTM Operating Income, EV/NTM Operating Income, EV/LTM EBITDAS and EV/NTM EBITDAS for this transaction were excluded for purposes of determining the respective selected multiple ranges and in the calculations of the low, median and high because financial information was not publicly available.

(3) EV/NTM Revenue, EV/NTM Operating Income and EV/NTM EBITDAS for this transaction were excluded for purposes of determining the respective selected multiple ranges and in the calculations of the low, median and high because financial information was not publicly available.

(4) EV/NTM Operating Income, EV/LTM EBITDAS and EV/NTM EBITDAS for this transaction were excluded for purposes of determining the respective selected multiple ranges and in the calculations of the low, median and high because financial information was not publicly available. The EV/LTM Operating Income multiple for this transaction was deemed not meaningful due to a negative value.

(5) EV/LTM Operating Income, EV/NTM Operating Income, EV/LTM EBITDAS and EV/NTM EBITDAS for this transaction were excluded for purposes of determining the respective selected multiple ranges and in the calculations of the low, median and high because financial information was not publicly available.

As part of its precedent transactions analysis, for each of the selected transactions, based on information Barclays obtained from publicly available information, Barclays analyzed the EV to(i) last-12-months for which financial information was publicly available, or LTM, revenue and the subsequent12-months, or NTM, revenue, (ii) LTM operating income and NTM operating income and (iii) LTM EBITDAS and NTM EBITDAS. As part of its precedent transactions analysis, for each of the selected transactions, based on information Barclays obtained from publicly available information, Barclays also analyzed NTM revenue growth to LTM revenue growth.

The reasons for and the circumstances surrounding each of the selected precedent transactions analyzed were diverse and there are inherent differences in the business, operations, financial conditions and prospects of Finisar and the companies included in the selected precedent transaction analysis. Accordingly, Barclays believed that a purely quantitative selected precedent transaction analysis would not be particularly meaningful in the context of considering the proposed transaction. Barclays therefore made qualitative judgments concerning differences between the characteristics of the selected precedent transactions and the proposed transaction which would affect the acquisition values of the selected target companies and Finisar. Based upon these judgments, Barclays selected a range of multiples for Finisar and applied such range to the Finisar Projections to calculate a range of implied prices per share of Finisar Common Stock. The following table summarizes the result of these calculations:

	Low		Median		High		Selected Multiple Range		Implied Value per Share of Finisar
EV/LTM Revenue		1.06x		1.85x		6.57x		1.60x – 2.40x	$	19.23 – $27.50
EV/NTM Revenue		1.24x		1.95x		5.35x		1.50x – 2.20x	$	19.23 – $26.95
EV/LTM Operating Income		7.1x		12.9x		31.5x		15.0x – 18.0x	$	11.30 – $13.04
EV/NTM Operating Income		8.4x		12.4x		20.8x		12.0x – 15.0x	$	14.57 – $17.56
EV/LTM EBITDAS		6.6x		10.4x		16.2x		9.5x – 11.0x	$	15.78 – $17.86
EV/NTM EBITDAS		7.1x		10.3x		14.3x		9.0x – 11.0x	$	19.30 – $23.00

109

Barclays noted that on the basis of the selected precedent transaction analysis, the implied value of the Merger Consideration of $26.00 per share of Finisar Common Stock was (i) above the range of implied values per share of Finisar Common Stock calculated using EV/LTM operating income, EV/NTM operating income, EV/LTM EBITDAS and EV/NTM EBITDAS and (ii) within the range of implied values per share of Finisar Common Stock calculated using EV/LTM revenue and EV/NTM revenue.

Discounted Cash Flow Analysis

In order to estimate the present value of Finisar Common Stock, Barclays performed a discounted cash flow analysis of Finisar. A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the “present value” of estimated future cash flows of the asset. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors.

Barclays performed a discounted cash flow analysis of Finisar based on estimates of unlevered free cash flows of Finisar as reflected in the Finisar Projections to derive a range of implied present values per share of Finisar Common Stock as of November 8, 2018. Barclays used themid-year convention in its discounted cash flow analysis to more accurately reflect the present value of future cash flows because cash flows are actually earned throughout the year rather than at the end of the year. Utilizing discount rates ranging from 11.0% to 12.0%, reflecting estimates of Finisar’s weighted average cost of capital, or WACC, Barclays derived a range of implied EVs for Finisar by discounting to present value as of November 8, 2018, (i) estimates of unlevered free cash flows of Finisar for the stub period from November 8, 2018 through April 30, 2019 and for the fiscal years 2020 and 2021 based on the Finisar Projections and (ii) a range of terminal values for Finisar derived by applying perpetuity growth rates ranging from 2.0% to 4.0% to the estimated terminal unlevered free cash flow for Finisar calculated based upon the Finisar Projections. The range ofafter-tax discount rates of 11.0% to 12.0% was selected based on an analysis of the WACC of Finisar and the comparable companies. Theafter-tax unlevered free cash flows were calculated by taking theafter-taxnon-GAAP operating income of Finisar (which did not include stock-based compensation as an expense), adding depreciation, and subtracting capital expenditures and adjusting for changes in net working capital. In calculating theafter-tax unlevered free cash flows, it was assumed that capital expenditures would equal depreciation and amortization in the terminal year. To calculate estimated EVs, Barclays then added the present value of the terminal values to the present values of the unlevered free cash flows for the stub period from November 8, 2018 through April 30, 2019 and for the fiscal years 2020 and 2021. Barclays then calculated a range of implied prices per share of Finisar by subtracting net debt (found by subtracting the value of Finisar’s short term cash and short term investments from the principal amount of its total convertible debt) as of July 29, 2018 from the estimated EVs using the discounted cash flow method and dividing such amount by the diluted number of shares of Finisar Common Stock, calculated using the treasury stock method, and using the number of shares of Finisar Common Stock, Finisar Stock Options and Finisar Restricted Stock Units outstanding as of November 6, 2018. This analysis implied a range of value per share of Finisar Common Stock of $22.38 to $30.64.

Barclays noted that on the basis of the discounted cash flow analysis, the implied value of the Merger Consideration of $26.00 per share of Finisar Common Stock was within the range of implied values per share calculated using the Finisar Projections.

Other Factors

Barclays also reviewed and considered other factors, which were not considered part of its financial analyses in connection with rendering its opinion, but were references for informational purposes, including, among other things, the Research Analysts Price Targets Analysis for Finisar andII-VI, Historical Share Price Analysis for Finisar andII-VI, and Premiums Paid Analysis described below.

Discounted Cash Flow Analysis for II-VI

In order to estimate the present value of II-VI Common Stock, Barclays performed a discounted cash flow analysis of II-VI based on estimates of unlevered free cash flows of II-VI as reflected in the Barclays Fairness Opinion II-VI projections to derive a range of implied present values per share of II-VI Common Stock as of November 8, 2018. In performing a discounted cash flow analysis of II-VI, Barclays used a methodology similar to the methodology it used in performing a discounted cash flow analysis of Finisar. Utilizing discount rates ranging from 10.0% to 11.0%, reflecting estimates of II-VI’s WACC, Barclays derived a range of implied EVs for II-VI by discounting to present value as of November 8, 2018, (i) estimates of unlevered free cash flows of II-VI for the stub period from November 8, 2018 through June 30, 2019 and for the fiscal years 2020 through 2023 based on the Barclays Fairness Opinion II-VI projections and (ii) a range of terminal values for Finisar derived by applying perpetuity growth rates ranging from 2.0% to 4.0% to the estimated terminal unlevered free cash flow for II-VI calculated based upon the Barclays Fairness Opinion II-VI projections. This analysis implied a range of value per share of II-VI Common Stock of $68.60 to $100.56.

Research Analysts Price Targets Analysis for Finisar andII-VI

Barclays reviewed publicly available research on per share price targets for Finisar Common Stock andII-VI Common Stock obtained from brokers. The equity research analysts’ per share price targets ranged from $19.00 to $26.00 for Finisar and from $41.00 to $64.00 forII-VI. The publicly available per share price targets published by equity research firms do not necessarily reflect the current market trading price of Finisar Common Stock orII-VI Common Stock, respectively, and these estimates are subject to uncertainties, including future financial performance of Finisar andII-VI as well as future market conditions.

Historical Share Price Analysis of Finisar andII-VI

To illustrate the trend in the historical trading prices of Finisar Common Stock, Barclays considered historical data with regard to the trading prices of Finisar Common Stock over the52-week period prior to the announcement of the proposed transaction. During such period, the per share closing price of Finisar Common Stock ranged from $14.67 to $23.70.

To illustrate the trend in the historical trading prices ofII-VI Common Stock, Barclays considered historical data with regard to the trading prices ofII-VI Common Stock over the52-week period prior to the announcement of the proposed transaction. During such period, the per share closing price ofII-VI Common Stock ranged from $35.59 to $52.95.

Premiums Paid Analysis

In order to assess the premium offered to the stockholders of Finisar in the proposed transaction relative to the premiums offered to stockholders in other transactions, Barclays reviewed the premium paid in all electronics mergers and acquisitions transactions valued between $1.0 billion and $5.0 billion from January 1, 2010 to November 8, 2018, of which there were 44. For each transaction, Barclays calculated the premium per share paid by the acquirer by comparing the announced transaction value per share to the target company’s historical average share price during the following periods: (i) closing price on the last trading day prior to announcement of the transaction or first reference in the public news media about the transaction and (ii) average closing price for the 30 calendar days prior to announcement of the transaction or first reference in the public news media about the transaction.

The reasons for and the circumstances surrounding each of the transactions analyzed in the transaction premium analysis were diverse and there are inherent differences in the business, operations, financial conditions and prospects of Finisar,II-VI and the companies included in the transaction premium analysis. Accordingly, Barclays believed that a purely quantitative transaction premium analysis would not be particularly meaningful in the context of considering the proposed transaction. Barclays therefore made qualitative judgments concerning

111

the differences between the characteristics of the selected transactions and the proposed transaction that would affect the acquisition values of the target companies and Finisar. Based upon these judgments, Barclays selected a range of premiums (i) to the closing price of Finisar Common Stock on November 8, 2018 (the last unaffected trading day prior to the first reference to a potential sale of Finisar in the public news media) and (ii) the30-day average of the closing prices of Finisar Common Stock ended on November 8, 2018, to calculate a range of implied prices per share of Finisar Common Stock. The following summarizes the result of these calculations:

	Selected Premium Range			Implied Value per Finisar Share
1-Day Unaffected Price		16% – 45	%	$	21.90 – $27.44
30-Day Average Unaffected Price		22% – 48	%	$	20.76 – $25.34

Barclays noted that on the basis of the transaction premium analysis, the implied value of the Merger Consideration of $26.00 per share of Finisar Common Stock was (i) within the range of implied values per share calculated using the closing price of Finisar Common Stock on November 8, 2018 and (ii) above the range of implied values per share calculated using the30-day average of the closing price of Finisar Common Stock ending on November 8, 2018.

BofA Merrill Lynch expressed no opinion or view as to any terms or other aspects or implications of the Merger (other than the Merger Consideration to the extent expressly specified in its opinion), including, without

114

limitation, the form or structure of the Merger, any related transactions or any other agreement, arrangement or understanding entered into in connection with or related to the Merger or otherwise. BofA Merrill Lynch’s opinion was limited to the fairness, from a financial point of view, toII-VI of the Merger Consideration to be paid in the Merger and no opinion or view was expressed with respect to any consideration received in connection with the Merger by the holders of any class of securities, creditors or other constituencies of any party.

The discussion set forth below in the sections entitled “Summary of Material Finisar Financial Analyses” and “Summary of MaterialII-VI Financial Analyses” represents a brief summary of the material financial analyses presented by BofA Merrill Lynch to theII-VI Board in connection with its opinion.The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses performed by BofA Merrill Lynch, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses performed by BofA Merrill Lynch. Considering the data set forth in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses performed by BofA Merrill Lynch. In addition,II-VI, Finisar and the other publicly traded companies reviewed byBofA Merrill Lynch in connection with its analyses have different fiscal year ends. Accordingly, for purposes of its financial analyses and for ease of reference, BofA Merrill Lynch conformed information contained in the Finisar management projections and the financial and stock market information for the publicly traded companies it reviewed to reflect fiscal years ending on June 30, to be consistent with and comparable toII-VI’s fiscal year.

Summary of Material Finisar Financial Analyses

Selected Publicly Traded Companies Analysis.BofA Merrill Lynch reviewed publicly available financial and stock market information for Finisar and the following 10 publicly traded companies with material operations engaged in the manufacturing of components for optical communications and/or the laser industry:

• Acacia Communications, Inc.

115

• Coherent, Inc.

• Cree, Inc.

• II-VI Incorporated

• Inphi Corporation

• IPG Photonics Corporation

• Lumentum Holdings, Inc,

• MKS Instruments, Inc.

• NeoPhotonics Corporation

• Novanta, Inc.

BofA Merrill Lynch reviewed, among other things, per share equity values, based on closing stock prices on November 7, 2018, of the selected publicly traded companies as a multiple of June 30, 2019 and 2020 estimated earnings per share, plus amortization of intangibles, stock-based compensation and certainone-time costs, referred to in this section as adjusted EPS. The overall low to high June 30, 2019 estimated adjusted EPS multiples observed for selected publicly traded companies were 7.4x to 40.6x (with a mean of 21.4x and a median of 18.6x), and the overall low to high June 30, 2020 estimated adjusted EPS multiples observed for such companies were 6.8x to 31.5x (with a mean of 19.4x and a median of 18.1x). BofA Merrill Lynch also reviewed enterprise values of the selected publicly traded companies, calculated as equity values based on closing stock prices on November 7, 2018, plus debt and preferred equity, and less cash and cash equivalents (referred to collectively in this section as net debt), as a multiple of 2019 and 2020 estimated earnings before interest, taxes, depreciation and amortization, commonly referred to as EBITDA. The overall low to high June 30, 2019 EBITDA multiples observed for selected publicly traded companies were 6.6x to 29.4x (with a mean of 15.6x and a median of 14.5x), and the overall low to high June 30, 2020 EBITDA multiples observed for selected publicly traded companies were 6.3x to 19.8x (with a mean of 12.6x and a median of 11.6x).

BofA Merrill Lynch then applied June 30, 2019 adjusted EPS multiples of 15.0x to 18.0x and June 30, 2020 adjusted EPS multiples of 11.0x to 15.0x derived from the selected publicly traded companies based on its professional judgment and experience to Finisar’s June 30, 2019 and June 30, 2020 estimated adjusted EPS. BofA Merrill Lynch also applied 2019 EBITDA multiples of 7.0x to 11.0x and 2020 EBITDA multiples of 6.0x to 9.0x derived from the selected publicly traded companies based on its professional judgment and experience to Finisar’s June 30, 2019 and June 30, 2020 estimated EBITDA to calculate indicative enterprise values, from which BofA Merrill Lynch subtracted net debt as of July 29, 2018 to derive equity values. Estimated financial data of the selected publicly traded companies were based on publicly available research analysts’ estimates, and estimated financial data of Finisar were based on the adjusted Finisar projections. This analysis indicated the following approximate implied per share equity value reference ranges for Finisar, as compared to the Merger Consideration, which BofA Merrill Lynch deemed to have a value of $26.00 per share of Finisar Common Stock for purposes of its analyses:

Implied Per Share Equity Value Reference Ranges for Finisar				Merger Consideration
2019E P/EPS	2020E P/EPS	2019E EV/EBITDA	2020E EV/EBITDA
$15.60 – $18.70	$20.90 – $28.45	$15.25 – $22.50	$19.70 – $28.20	$26.00

No company used in this analysis is identical or directly comparable to Finisar. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading or other values of the companies to which Finisar was compared.

Newport Corporation	Ophir Optronics Ltd.

BofA Merrill Lynch reviewed transaction values, calculated as the enterprise value implied for the target company based on the consideration payable in the selected transaction, as a multiple of the target company’s estimated EBITDA for the next 12 months (referred to in this section as NTM EBITDA). The overall low to high multiples of the target companies’ estimated NTM EBITDA for the selected transactions were 7.6x to 34.8x (with a mean of 15.8x and a median of 13.8x). BofA Merrill Lynch then applied estimated NTM EBITDA multiples of 10.0x to 14.0x derived from the selected transactions based on its professional judgment and experience to the estimated NTM EBITDA for Finisar as of June 30, 2018 to calculate indicative enterprise values, from which BofA Merrill Lynch subtracted net debt as of July 29, 2018 to derive equity values.Estimated financial data of the selected transactions were based on publicly available information. Estimated financial data of Finisar were based on the adjusted Finisar projections. This analysis indicated the following approximate implied per share equity value reference ranges for Finisar, as compared to the Merger Consideration of $26.00 per share of Finisar Common Stock:

Implied Per Share Equity Value Reference Range for Finisar	Merger Consideration
$20.30 – $27.35	$	26.00

No company, business or transaction used in this analysis is identical or directly comparable to Finisar or the Merger. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the acquisition or other values of the companies, business segments or transactions to which Finisar and the Merger were compared.

Discounted Cash Flow Analysis.BofA Merrill Lynch performed a discounted cash flow analysis of Finisar to calculate the estimated present value of the standalone unlevered,after-tax free cash flows that Finisar was forecasted to generate from June 30, 2018 through 2023 based on the adjusted Finisar projections, both (i) taking

117

into account the value per share of assumed cost savings in the amount of $150 million at perpetuity growth rates of 0.0% to 2.5%, phased in $35 million in year 1, $100 million in year 2 and $150 million in year 3, and assumingone-time costs to achieve such cost savings equal to $75 million in year 1 and $50 million in year 2, and incremental capital expenditures of $5 million in year 1, $20 million in year 2 and $9 million in year 3, and (ii) without taking into account such assumed cost savings. BofA Merrill Lynch calculated terminal values for Finisar by extrapolating Finisar’s normalized unlevered free cash flow at perpetuity growth rates of 3.5% to 4.0%, which perpetuity growth rates were selected based on BofA Merrill Lynch’s professional judgment and experience. The cash flows and terminal values were then discounted to present value as of June 30, 2018, assuming amid-year convention, using discount rates ranging from 8.75% to 11.00%, which were based on an estimate of Finisar’s weighted average cost of capital. To the resulting enterprise values, BofA Merrill Lynch subtracted net debt, estimated as of June 30, 2018, to derive equity values. This analysis indicated the following approximate implied per share equity value reference ranges for Finisar as compared to the Merger Consideration of $26.00 per share of Finisar Common Stock:

Implied Per Share Equity Value Reference Range for Finisar		Merger Consideration
Standalone	Taking Into Account Cost Savings
$18.70 – $28.95	$25.30 – $41.30	$26.00

Summary of MaterialII-VI Financial Analyses

BofA Merrill Lynch performed has/gets analyses comparing the illustrative (i) present value of the future price ofII-VI Common Stock, (ii) public market trading price forII-VI Common Stock and (iii) intrinsic value ofII-VI, assuming (x) in one case the pro forma ownership byII-VI shareholders of the combined company following the Merger, and (y) in another case the 100% ownership byII-VI shareholders of theII-VI Common Stock on a stand-alone basis. The actual results achieved by the combined company in each case may vary from projected results, and the variations may be material.

Present Value of Future Stock Price.BofA Merrill Lynch performed an analysis to derive implied present values of hypothetical future prices forII-VI Common Stock on a stand-alone basis, and on a pro forma basis after giving effect to the Merger, in each case as of June 30 of 2020 through 2022. BofA Merrill Lynch calculated hypothetical future prices forII-VI Common Stock by applying an illustrative weighted average estimated 2019 adjusted EPS multiple of 19.6x for the stand-alone case and 18.6x for the pro forma case (calculated by using illustrative Finisar andII-VI five-year average NTM adjusted EPS multiples of 17.4x and 19.6x, respectively) to estimated adjusted EPS and pro forma adjusted EPS forII-VI for the following year, in each case as of June 30 of 2020 through 2022, as reflected in theII-VI projections and the estimated cost savings. The resulting hypothetical future stock prices were then discounted to present value as of November 8, 2018 using a discount rate of 11.0%, based on an estimate ofII-VI’s cost of equity. This analysis indicated approximate implied present values for the price ofII-VI Common Stock, on a stand-alone and pro forma basis, ranging from $83.14 to $105.86 and $100.21 to $119.90, respectively. This analysis indicated that the present value of the hypothetical June 2022 pro forma future stock price (giving effect to the Merger) would represent a 13.3% premium to the present value of the hypothetical June 2022 stand-alone future stock price.

Public Market Valuation. BofA Merrill Lynch reviewed the potential pro forma financial effect of the Merger on the market value ofII-VI Common Stock. BofA Merrill Lynch calculated an illustrative pro forma market value for theII-VI Common Stock as comprising 69% of the sum of (i) the aggregate market value of theII-VI Common Stock based on its closing price of $46.26 per share as of November 7, 2018, (ii) the aggregate market value of the Finisar Common Stock based on its closing price of $17.93 as of November 7, 2018, and (iii) the value of the $150 million of assumed annual cost savings, based on a 10.0x pro forma EBITDA multiple, less (iv) thetax-effectedone-time costs required to achieve the cost savings and less (v) the incremental net debt incurred to fund the Merger. This analysis resulted in an illustrative pro forma market value for theII-VI Common Stock, after giving effect to the Merger, of $49.09 per share, as compared with the actual closing price for theII-VI Common Stock of $46.26 per share as of November 7, 2018.

Intrinsic Valuation. BofA Merrill Lynch reviewed the potential pro forma financial effect of the Merger on the intrinsic discounted cash flow value ofII-VI Common Stock. BofA Merrill Lynch calculated an illustrative pro forma intrinsic value for theII-VI Common Stock as comprising 69% of the sum of (i) the implied aggregate value of theII-VI Common Stock derived from a discounted cash flow analysis ofII-VI similar to that described above under “Summary of Material Finisar Financial Analyses — Discounted Cash Flow Analysis,” based on theII-VI projections, (ii) the implied aggregate value of the Finisar Common Stock derived from the discounted cash flow analysis of Finisar described above under “Summary of Material Finisar Financial Analyses — Discounted Cash Flow Analysis” and (iii) the present value of the net cost savings assumed to be realized from the Merger, less (iv) the incremental net debt incurred to fund the Merger. For purposes of its discounted cash flow analysis ofII-VI, BofA Merrill Lynch calculated terminal values forII-VI by extrapolatingII-VI’s normalized unlevered free cash flow at perpetuity growth rates of 3.5% to 4.0%, which perpetuity growth rates were selected based on BofA Merrill Lynch’s professional judgment and experience. The cash flows to and terminal values were then discounted to present value as of June 30, 2018, assumingmid-year convention and using discount rates ranging from 8.75% to 11.00%, which were based on an estimate ofII-VI’s weighted average cost of capital. From the resulting enterprise values, BofA Merrill Lynch subtracted net debt, estimated as of June 30, 2018, to derive equity values. Estimated financial data ofII-VI were based on theII-VI projections and estimated financial data of Finisar were based on the adjusted Finisar projections, respectively. This analysis indicated that the Merger could result in dilution of 49.3% to accretion of 57.3% in the intrinsic discounted cash flow valuation ofII-VI Common Stock.

Other Factors

BofA Merrill Lynch also noted certain additional factors that were not considered part of BofA Merrill Lynch’s material financial analyses with respect to its opinion but were referenced for informational purposes, including, among other things, the following:

• historical trading prices of Finisar Common Stock during the52-week period ended November 7, 2018, which indicated that during such period Finisar’s closing prices ranged from $14.67 to $23.70;

• one-year forward stock price targets as of November 7, 2018, for Finisar Common Stock in publicly available Wall Street research analyst reports, which indicated stock price targets for Finisar, discounted to present value as of November 7, 2018 utilizing a discount rate of 10.00%, of approximately $17.25 to $23.65 per share; and

• the relationship between movements in Finisar Common Stock andII-VI Common Stock during the five-year period ended November 7, 2018.

Miscellaneous

As noted above, the discussion set forth above in the sections entitled “Summary of Material Finisar Financial Analyses” and “Summary of MaterialII-VI Financial Analyses” is a summary of the material financial analyses presented by BofA Merrill Lynch to theII-VI Board in connection with its opinion and is not a comprehensive description of all analyses undertaken or factors considered by BofA Merrill Lynch in connection with its opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to partial analysis or summary description. BofA Merrill Lynch believes that its analyses summarized above must be considered as a whole. BofA Merrill Lynch further believes that selecting portions of its analyses and the factors considered or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying BofA Merrill Lynch’s analyses and opinion. The fact that any specific analysis has been referred to in the summary above is not meant to indicate that such analysis was given greater weight than any other analysis referred to in the summary.

119

In performing its analyses, BofA Merrill Lynch considered industry performance, general business and economic conditions and other matters, many of which are beyond the control of Finisar andII-VI. The estimates of the future performance of Finisar andII-VI in or underlying BofA Merrill Lynch’s analyses are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than those estimates or those suggested by BofA Merrill Lynch’s analyses. These analyses were prepared solely as part of BofA Merrill Lynch’s analysis of the fairness, from a financial point of view, toII-VI of the Merger Consideration to be paid byII-VI in the Merger and were provided to theII-VI Board in connection with the delivery of BofA Merrill Lynch’s opinion. The analyses do not purport to be appraisals or to reflect the prices at which a company might actually be sold or the prices at which any securities have traded or may trade at any time in the future. Accordingly, the estimates used in, and the ranges of valuations resulting from, any particular analysis described above are inherently subject to substantial uncertainty and should not be taken to be BofA Merrill Lynch’s view of the actual values of Finisar orII-VI.

The type and amount of consideration payable in the Merger was determined through negotiations between Finisar andII-VI, rather than by any financial advisor, and was approved by theII-VI Board. The decision to enter into the Merger Agreement was solely that of theII-VI Board. As described above, BofA Merrill Lynch’s opinion and analyses were only one of many factors considered by theII-VI Board in its evaluation of the proposed Merger and should not be viewed as determinative of the views of theII-VI Board or management with respect to the Merger or the Merger Consideration.

II-VI has agreed to pay BofA Merrill Lynch for its services in connection with the Merger an aggregate fee currently estimated to be approximately $29,000,000, approximately $2,000,000 will be payable in connection with delivery of its opinion and the remaining portion of which is contingent upon consummation of the Merger.II-VI also has agreed to reimburse BofA Merrill Lynch for its expenses incurred in connection with BofA Merrill Lynch’s engagement and to indemnify BofA Merrill Lynch, any controlling person of BofA Merrill Lynch and each of their respective directors, officers, employees, agents and affiliates against specified liabilities, including liabilities under the federal securities laws.

BofA Merrill Lynch and its affiliates comprise a full service securities firm and commercial bank engaged in securities, commodities and derivatives trading, foreign exchange and other brokerage activities, and principal investing as well as providing investment, corporate and private banking, asset and investment management, financing and financial advisory services and other commercial services and products to a wide range of companies, governments and individuals. In the ordinary course of their businesses, BofA Merrill Lynch and its affiliates may invest on a principal basis or on behalf of customers or manage funds that invest, make or hold long or short positions, finance positions or trade or otherwise effect transactions in equity, debt or other securities or financial instruments (including derivatives, bank loans or other obligations) ofII-VI, Finisar and certain of their respective affiliates.

BofA Merrill Lynch and its affiliates in the past have provided, currently are providing, and in the future may provide investment banking, commercial banking and other financial services toII-VI and have received or in the future may receive compensation for the rendering of these services, including (i) having acted or acting as aco-lead arranger for, and as a lender under,II-VI’s revolving credit facility, (ii) having acted as a book running manager in a convertible bond offering forII-VI, (iii) having provided or providing foreign exchange trading services toII-VI, and (iv) having provided or providing certain treasury management services and products toII-VI. From October 1, 2016 through September 30, 2018, BofA Merrill Lynch and its affiliates derived aggregate revenues fromII-VI and its affiliates of approximately $11 million for investment and corporate banking services.

In addition, BofA Merrill Lynch and its affiliates in the past have provided, currently are providing and in the future may provide investment banking, commercial banking and other financial services to Finisar and have received or in the future may receive compensation for the rendering of these services, including having acted as a book running manager in a convertible bond offering for Finisar and having provided or providing foreign

120

exchange and fixed income trading services to Finisar. From October 1, 2016 through September 30, 2018, BofA Merrill Lynch and its affiliates derived aggregate revenues from Finisar and its affiliates of approximately $4.5 million for investment and corporate banking services.

Unaudited Prospective Financial Information

Finisar Projections

Although Finisar historically has publicly issued limited short-term guidance concerning certain aspects of its expected financial performance, it does not, as a matter of course, make public disclosure of detailed forecasts or projections of its expected financial performance for extended periods due to, among other things, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. In connection with Finisar’s evaluation of strategic alternatives and a possible business combination transaction involving Finisar, in August 2018, Finisar prepared certain unaudited projections and estimates of future financial and operating performance with respect to Finisar’s fiscal years ending in 2019, 2020 and 2021, which are referred to in this joint proxy statement/prospectus as the Finisar management projections, which it made available toII-VI and BofA Merrill Lynch on August 27, 2018. The Finisar management projections also were provided to Barclays for its use and reliance in connection with its respective financial analysis and opinion in connection with the Merger.

The Finisar management projections were prepared on a stand-alone basis and do not take into account any of the transactions contemplated by the Merger Agreement, including the Merger and associated expenses, or Finisar’s compliance with its covenants under the Merger Agreement. For these reasons and for the reasons described above, actual results likely will differ, and may differ materially, from those contained in the Finisar management projections.

The Finisar management projections have been prepared by, and are the responsibility of, Finisar management for internal use by Finisar and Barclays, and approved by the Finisar Board, and were provided to Barclays for use in the financial analyses undertaken by representatives of Barclays in connection with Barclays’ rendering its opinion to the Finisar Board and were not prepared for purposes of public disclosure.    

The following table presents a summary of the unaudited Finisar management projections⁽¹⁾⁽²⁾:

(in millions, except per share data and percentages)	FY2019			FY2020			FY2021			CY2018(3)			CY2019(4)
Revenue	$	1,321		$	1,657		$	1,860		$	1,292		$	1,548
Non-GAAP Gross Margin		27.6	%		31.7	%		34.0	%		27.1	%		30.5	%

Non-GAAP Fully Diluted EPS	$	0.89		$	2.11		$	2.76		$	0.70		$	1.71

(1) The Finisar management projections were calculated excluding certain charges and credits that would be required by U.S. generally accepted accounting principles, or GAAP, considered by management to be outside of Finisar’s core ongoing operating results in the same manner as Finisar has historically calculated financial information on anon-GAAP basis. These excluded items have historically consisted of, among others: (i) amortization of acquired technology(non-cash charges related to technology obtained in acquisitions); (ii) stock-based compensation expense(non-cash charges); (iii) impairment of long-lived/intangible assets(non-cash charges); (iv) reduction in force costs and other restructuring charges(non-core

121

cash charges); (v) acquisition related retention payments(non-core cash charges); (vi) inventory write-offs related to discontinued products(non-cash charges); (vii) discontinued product services fees(non-core cash charges); (viii) duplicate facility costs during facility move(non-core cash charges); (ix) acquisition related costs(non-core cash charges); (x) litigation settlements and resolutions and related costs(non-core cash charges); (xi) amortization of purchased intangibles(non-core,non-cash charges); (xii)start-up cash costs related to Finisar’s Sherman VCSEL fab until Finisar begins commercial production; (xiii) imputed interest expenses on convertible debt(non-cash charges); (xiv) imputed interest related to restructuring(non-cash charges); (xv) other interest income(non-core benefits); (xvi) gains and losses on sales of assets and other miscellaneous(non-cash losses and cash gains related to the periodic disposal of assets no longer required for current activities); (xvii) loss (gain) related to minority investments(non-core charges or benefits); (xviii) dollar denominated foreign exchange transaction losses (gains)(non-cash charges or benefits); and (xix) amortization of debt issuance costs(non-cash charges). In addition, the Finisar management projections have adjustednon-GAAP income andnon-GAAP income per share for the difference between GAAP income taxes andnon-GAAP income taxes.

(2) All fiscal year periods assume a52-week year.

(3) “CY2018” has been prepared using the sum of the implied calendar quarters based on historical fiscal quarter financial data and fiscal quarter projections provided by Finisar. Calendar quarter financials have been prepared using the following formulae based on historical fiscal quarter financial data and fiscal quarter projections provided by Finisar:

CQ1 2018 = (0.326*FQ3 2018) + (0.674*FQ4 2018)

CQ2 2018 = (0.326*FQ4 2018) + (0.674*FQ1 2019)

CQ3 2018 = (0.326*FQ1 2019) + (0.674*FQ2 2019)

CQ4 2018 = (0.326*FQ2 2019) + (0.674*FQ3 2019).

(4) “CY2019” has been prepared using the following formula based on fiscal year projections provided by Finisar: CY2019 = (0.326*FY2019) + (0.674*FY2020).

The following is a summary of the projected unlevered free cash flow, which is derived from the Finisar management projections summarized in the table above.

(in millions)	Stub FY2019(1)		FY2020		FY2021
Revenue	$	649	$	1,657	$	1,860
Non-GAAP EBITDAS	$	101	$	380	$	478
Non-GAAP EBIT	$	50	$	258	$	344
Non-GAAP NOPAT	$	46	$	236	$	316
Non-GAAP Unlevered Free Cash Flow(2)	$	8	$	126	$	247

(1) FY2019 stub period is from November 8, 2018 to April 30, 2019.

(2) “Unlevered Free Cash Flow” is anon-GAAP financial measure calculated by starting with net operating profit after tax, or NOPAT, and adding back depreciation and then subtracting change in net working capital and capital expenditures. Net working capital projections used to calculate Unlevered Free Cash Flow are based on FY2017 and FY2018 historical levels. It is also assumed that capital expenditures equal depreciation in the terminal year.

Adjusted Finisar Projections

In connection with its evaluation of the Merger,II-VI made certain adjustments to the assumptions and estimates underlying the Finisar management projections in light of, among other things, the fact thatII-VI and Finisar have different fiscal years, the due diligenceII-VI conducted on Finisar, and certain macroeconomic and

122

industry trends.II-VI’s adjusted version of the Finisar management projections are referred to in this section of this joint proxy statement/prospectus as the “adjusted Finisar projections.” The adjusted Finisar projections were made available byII-VI management to BofA Merrill Lynch for purposes of its financial analysis and opinion.II-VI directed BofA Merrill Lynch to use and rely upon (and BofA Merrill Lynch accordingly used and relied upon) the adjusted Finisar projections for purposes of its financial analysis and opinion (see “The Merger — Opinion ofII-VI’s Financial Advisor” beginning on page 112 of this joint proxy statement/prospectus). TheII-VI Board also reviewed and considered the adjusted Finisar projections in connection with its review of BofA Merrill Lynch’s financial analysis at the meeting of theII-VI Board held on November 8, 2018.

The following table presents a summary of the unaudited adjusted Finisar projections.⁽¹⁾

	FY19			FY20		FY21		FY22(2)		FY23(3)
	(in millions, except per share amounts)
Revenues	$	1,377		$	1,691	$	1,877	$	1,979	$	2,060

Non-GAAP Unlevered Free Cash Flow(4)		(148	)		76		195		211		228

(1) The Finisar management projections have been adjusted to correspond withII-VI’s fiscal year periods.

(2) FY22 projections prepared exclusively byII-VI management.

(3) FY23 projections prepared exclusively byII-VI management.

(4) Non-GAAP Unlevered Free Cash Flow defined as earnings before interest, taxes and amortization, less taxes, plus depreciation, less change in net working capital and less capital expenditures.

The adjusted Finisar projections were not prepared with a view to public disclosure and are included in this joint proxy statement/prospectus only because such information was made available, in whole or in part, to BofA Merrill Lynch for purposes of its financial analysis and opinion (see “The Merger — Opinion ofII-VI’s Financial Advisor” beginning on page 112 of this joint proxy statement/prospectus) and to theII-VI Board.

II-VI Projections

In connection with its evaluation of the Merger,II-VI management prepared certain financial forecasts and unaudited prospective financial information relating toII-VI for the years ending June 30, 2019 through June 30, 2023 on a stand-alone basis, assumingII-VI would continue as an independent company, without giving effect to the Merger, consisting of certain baseII-VI projections andII-VI management adjustedII-VI projections, which are, together, referred to in this section of this joint proxy statement/prospectus as the“II-VI projections.” Certain of theII-VI projections for the years ending June 30, 2019 through June 30, 2023 were made available to Barclays and Finisar on or prior to October 23, 2018. TheII-VI projections for the year ending June 30, 2019 were subsequently updated byII-VI management and were provided to BofA Merrill Lynch on November 6, 2018 for purposes of its financial analysis and opinion (see “The Merger — Opinion ofII-VI’s Financial Advisor” beginning on page 112 of this joint proxy statement/prospectus).II-VI directed BofA Merrill Lynch to use and rely upon (and BofA Merrill Lynch accordingly used and relied upon) theII-VI projections for purposes of its financial analysis and opinion. TheII-VI Board also reviewed and considered theII-VI management adjustedII-VI projections at the meeting of theII-VI Board held on November 8, 2018.

TheII-VI projections reflect numerous assumptions and estimates thatII-VI made in good faith, including, without limitation, (i) that macroeconomic conditions will remain stable, both in the U.S. and globally; (ii) that no major changes occur in U.S. policy, laws and regulations; (iii) that gross margins in the industries served remain stable; (iv) that no new regulatory and business changes occur relating toII-VI’s business and operations; (v) that no major changes in industry pricing trends generally occur; and (vi) certain other matters referred to below under “The Merger — Unaudited Prospective Financial Information — General” beginning on page 127 of this joint proxy statement/prospectus. The baseII-VI projections also assume that GAAP as in effect as of the date the baseII-VI projections were made applies throughout the projection period.

123

The following table presents a summary of the baseII-VI projections:

	FY19			FY20		FY21		FY22		FY23
	(in millions, except per share amounts)
Revenues	$	1,378	(1)	$	1,677	$	2,025	$	2,422	$	2,792
EBIT(2)		176	(3)		312		432		582		728
Earnings Per Share		1.93	(4)		3.44		4.76		6.39		8.04

(1) FY19 revenue figure provided to Barclays and Finisar on October 23, 2018 was $1,375 million. BofA Merrill Lynch was subsequently provided an updated FY19 revenue figure of $1,378 million byII-VI management on November 6, 2018.

(2) EBIT defined byII-VI management as Earnings Before Interest and Taxes.

(3) FY19 EBIT figure provided to Barclays and Finisar on October 17, 2018 was $182.2 million. Certain updated financial information (not including GAAP FY19 EBIT) was provided by II-VI to Barclays on October 23, 2018, along with instructions on how to calculate GAAP FY19 EBIT based on the information included in the October 23, 2018 update, which would have resulted in an FY19 EBIT figure of $175.6 million. BofA Merrill Lynch was subsequently provided an updated FY19 EBIT figure of $176.4 million byII-VI management on November 6, 2018.

(4) FY19 EPS figure provided to Barclays on October 23, 2018 was $1.91. BofA Merrill Lynch was subsequently provided an updated FY19 EPS figure of $1.93 byII-VI management on November 6, 2018.

The following table presents a summary of theII-VI management adjustedII-VI projections:

	FY19			FY20		FY21		FY22		FY23
	(in millions, except per share amounts)
Revenues	$	1,378	(5)	$	1,677	$	2,025	$	2,422	$	2,792
Adjusted EBITDA(6)		314	(7)		467		608		780		945
Adjusted Earnings Per Share(8)		2.63	(9)		3.95		5.22		6.78		8.19
Unlevered Free Cash Flow(10)		(1	)(11)		50		196		343		481

(5) FY19 revenue figure provided to Barclays on October 23, 2018 was $1,374.8 million. BofA Merrill Lynch was subsequently provided an updated FY19 revenue figure of $1,378.2 million byII-VI management on November 6, 2018.

(6) Adjusted EBITDA defined byII-VI management as earnings before interest, taxes, depreciation and amortization, plus stock-based compensation and plus certainone-time costs.

(7) II-VI did not provide Barclays or Finisar with FY19 adjusted EBITDA figures.

(8) Adjusted EPS defined byII-VI management as earnings per share, plus after tax amortization of intangibles, plus after tax amortization ofnon-cash convertible note discount, plus after tax stock-based compensation, plus after tax certainone-time costs.

(9) FY19 adjusted EPS figure provided to Barclays on October 23, 2018 was $2.70 (see “Unaudited Prospective Financial Information — Barclays Fairness Opinion II-VI Projections”), which amount was calculated for that period only as follows: earnings per share, plus pre-tax amortization of intangibles, stock-based compensation, plus certain one time costs. BofA Merrill Lynch was subsequently provided an updated FY19 adjusted EPS figure of $2.63 byII-VI management on November 6, 2018, which amount was calculated using the methodology described in footnote (8) above. This difference in methodology of non-GAAP related adjustments, mainly related to amortization of non cash convertible note discount and income taxes, between the October 23, 2018 calculation of FY19 and the November 6, 2018 calculation of FY19 resulted in lower FY19 adjusted EPS by approximately $0.09. Thus, while the base II-VI projections for EPS increased by $0.02 between October 23, 2018 and November 6, 2018, the FY19 adjusted EPS projection declined from $2.70 to $2.63 between these dates as a result of this difference in methodology.

(10) Unlevered Free Cash Flow defined byII-VI management as earnings before interest, taxes and amortization, less taxes, plus depreciation, less change in net working capital and less capital expenditures.

(11) II-VI did not provide Barclays or Finisar with Unlevered Free Cash Flow figures.

124

EBIT, Adjusted EBITDA, Adjusted Earnings Per Share and Unlevered Free Cash Flow, as presented above, are each anon-GAAP financial measure. This information was not prepared for public disclosure.Non-GAAP financial measures should not be considered a substitute for, or superior to, financial measures determined or calculated in accordance with GAAP. Additionally,non-GAAP financial measures as presented byII-VI may not be comparable to similarly titled measures reported by other companies. In the view ofII-VI’s management, theII-VI projections were prepared on a reasonable basis based on the information available toII-VI’s management at the time of their preparation.

Barclays Fairness OpinionII-VI Projections

In connection with its evaluation of the Merger,II-VI management prepared certain financial forecasts and unaudited prospective financial information relating toII-VI for the years ending June 30, 2019 through June 30, 2023 on a stand-alone basis, assumingII-VI would continue as an independent company, without giving effect to the Merger. TheII-VI projections for the years ending June 30, 2019 through June 30, 2023 were made available to Finisar and Barclays on or prior to October 23, 2018, except as set forth in notes 1, 3, 5 and 9 of theII-VI projections (see “Unaudited Prospective Financial Information —II-VI Projections” beginning on page 123 of this joint proxy statement/prospectus). Barclays made certain adjustments and calculated certain amounts based on theII-VI projections made available to Finisar and Barclays on or prior to October 23, 2018, except as set forth in notes 1, 3, 5 and 9 of theII-VI projections, which adjusted and calculated amounts are referred to in this section of this joint proxy statement/prospectus as the “Barclays Fairness OpinionII-VI projections.” Barclays used and relied upon, among other things, the Barclays Fairness OpinionII-VI projections for purposes of its financial analysis and opinion (see “The Merger — Opinion of Finisar’s Financial Advisor” beginning on page 102 of this joint proxy statement/prospectus).

The following table presents a summary of the unaudited Barclays Fairness OpinionII-VI projections:

	FY19			FY20		FY21		FY22		FY23

Unlevered Free Cash Flow(5)		35			86		256		408		541

(1) Adjusted EBITDA defined byII-VI management as earnings before interest, taxes, depreciation and amortization, plus stock-based compensation and certainone-time costs related to certain acquisition costs.

(2) A figure for FY19 adjusted EBITDA was not included in theII-VI projections made available byII-VI to Finisar and Barclays on or prior to October 23, 2018. Based on theII-VI projections made available byII-VI to Finisar and Barclays on or prior to October 23, 2018, Barclays calculated FY19 adjusted EBITDA of $303 million.

(3) Adjusted Earnings Per Share defined byII-VI management for FY19 as earnings per share, pluspre-tax amortization of intangibles, stock-based compensation, plus certainone-time costs related to certain acquisition costs. Adjusted Earnings Per Share defined byII-VI management for FY20 through FY23 as earnings per share, plus after tax amortization of intangibles, plus after tax amortization ofnon-cash convertible note discount, plus after tax stock-based compensation, plus after tax certainone-time costs related to certain acquisition costs.

(4) The Barclays Fairness OpinionII-VI projections have subtracted, from the adjusted EPS figures included in theII-VI projections made available byII-VI to Finisar and Barclays on or prior to October 23, 2018, amortization ofnon-cash convertible note discount of $0.15, $0.15, $0.15, and $0.02 per share for FY20, FY21, FY22 and FY23, respectively.

(5) II-VI did not provide Barclays or Finisar with Unlevered Free Cash Flow figures. Barclays calculated Unlevered Free Cash Flow figures based on theII-VI projections made available byII-VI to Finisar and Barclays on or prior to October 23, 2018. Barclays calculated Unlevered Free Cash Flow as EBITA, minus

125

taxes, plus depreciation, minus change in net working capital, minus capital expenditures. EBITA is calculated by subtracting depreciation from adjusted EBITDA.

Neither theII-VI projections nor the Barclays Fairness OpinionII-VI projections were prepared with a view to public disclosure and are included in this joint proxy statement/prospectus only because such information was made available, in whole or in part, for purposes of Barclays’ financial analysis and opinion (see “The Merger — Opinion of Finisar’s Financial Advisor” beginning on page 102 of this joint proxy statement/prospectus) and to the Finisar Board.

II-VI Combined Company Projections

In connection with its evaluation of the Merger,II-VI management prepared certain pro forma financial forecasts and unaudited prospective financial information relating toII-VI and Finisar as a combined company for the years ending June 30, 2020 through June 30, 2023, giving effect to the Merger, which are referred to in this section of this joint proxy statement/prospectus as the“II-VI combined company projections.” TheII-VI combined company projections were provided to BofA Merrill Lynch for purposes of its financial analysis (see “The Merger — Opinion ofII-VI’s Financial Advisor” beginning on page 112 of this joint proxy statement/prospectus).II-VI directed BofA Merrill Lynch to use and rely upon (and BofA Merrill Lynch accordingly used and relied upon) theII-VI combined company projections for purposes of its financial analysis. TheII-VI Board also reviewed and considered theII-VI combined company projections at the meeting of theII-VI Board held on November 8, 2018.

TheII-VI combined company projections reflect numerous assumptions and estimates thatII-VI made in good faith in connection with the preparation of the adjusted Finisar projections and theII-VI management adjustedII-VI projections as more fully described in “— Adjusted Finisar Projections” and “—II-VI Projections” beginning on pages 122 and 123, respectively, of this joint proxy statement/prospectus. Additionally, theII-VI combined company projections reflect estimated cost synergies per year after completing the Merger due to increased operating efficiencies and leveraging economies of scale, which increase to approximately $150 million per year within 36 months of completing the Merger and thereafter.

It is important to note that certain items are not included in theII-VI combined company projections in any years. The intercompany revenue betweenII-VI and Finisar is not eliminated in theII-VI combined company projections. TheII-VI combined company projections also do not include expenses related to stock-based compensation, historic amounts for acquired amortization, the costs of achieving the stated synergies, thenon-cash portion of taxes, any of the income statement effects of Purchase Price Accounting including the inventory step up, amortization of intangibles and the appreciation of property, plant, and equipment, and any of the transaction fees of both companies related to the Merger including those to establish the financing. The unaudited and estimated amounts for the intercompany revenue elimination and the effects of the Purchase Price Accounting are shown in the unaudited pro forma condensed combined financial information as of June 30, 2018 in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 170 of this joint proxy statement/prospectus.

The following table presents a summary of theII-VI combined company projections:

	FY20		FY21		FY22		FY23
	(in millions, except per share amounts)
Pro Forma Revenues(1)	$	3,368	$	3,903	$	4,401	$	4,852
Pro Forma Adjusted EBITDA(2)		856		1,157		1,403		1,587
Pro Forma Adjusted Net Income(3)		440		678		877		1,029
Pro Forma Adjusted Earnings Per Share(4)		4.41		6.63		8.44		9.77

(1) Pro Forma Revenues reflects the sum of Revenues per theII-VI management adjustedII-VI projections and Revenues per the adjusted Finisar projections. Does not include any intercompany revenue eliminations between Finisar andII-VI.

126

(2) Pro Forma Adjusted EBITDA reflects the sum of Adjusted EBITDA per theII-VI management adjustedII-VI projections, Adjusted EBITDA per the adjusted Finisar projections and estimated cost synergies anticipated to be realized in each period.

(3) Pro Forma Adjusted Net Income reflects the sum ofII-VI adjusted net income (calculated as net income plus amortization of intangibles, plus amortization ofnon-cash convertible note discount, plus stock-based compensation, plus certainone-time costs),Non-GAAP Net Income per the Finisar management projections (as adjusted byII-VI management to correspond withII-VI’s fiscal year periods and for certain macroeconomic and industry trends), the estimatedafter-tax cost synergies anticipated to be realized in each period, and the impact of the interest from the anticipated financing for the Merger. These projections do not include stock compensation, amortization ofnon-cash convertible note discount (for this presentation only), historic amounts for acquired amortization, the costs of achieving the stated synergies, thenon-cash portion of taxes, any of the income statement effects of Purchase Price Accounting including the inventory step up, amortization of intangibles and the appreciation of property, plant, and equipment, and any of the transaction fees of both companies related to the Merger including those to establish the financing.

(4) Pro Forma Adjusted EPS reflects Pro Forma Adjusted Net Income divided by the anticipated number ofII-VI diluted shares outstanding after giving effect to the anticipated financing of the Merger and the redemption or repayment of the outstanding Finisar Convertible Notes (the latter for this presentation only).

Pro Forma Adjusted EBITDA, Pro Forma Adjusted Net Income and Pro Forma Adjusted Earnings Per Share, as presented above, are each anon-GAAP financial measure. This information was not prepared for public disclosure.Non-GAAP financial measures should not be considered a substitute for, or superior to, financial measures determined or calculated in accordance with GAAP. Additionally,non-GAAP financial measures as presented byII-VI may not be comparable to similarly titled measures reported by other companies. In the view ofII-VI’s management, theII-VI combined company projections were prepared on a reasonable basis based on the information available toII-VI’s management at the time of their preparation.

General

NeitherII-VI nor Finisar generally publishes its business plans and strategies or makes external disclosures of its anticipated financial position or results of operations due to, among other reasons, the uncertainty of the underlying assumptions and estimates, other than, (i) in the case ofII-VI, providing, from time to time, estimated ranges of certain expected financial results and operational metrics for the current year and certain future years in its regular earnings press releases and other investor materials and (ii) in the case of Finisar, providing, from time to time, estimated ranges of certain expected financial results and operational metrics for the current quarter in its regular earnings press releases and other investor materials.

The summaries of the parties’ respective projections included above are provided to give Finisar stockholders andII-VI shareholders access to certainnon-public information that was made available to Finisar,II-VI and their respective boards of directors and financial advisors in connection with the parties’ evaluation of the Merger, and are not included in this joint proxy statement/prospectus to influence any Finisar stockholder orII-VI shareholder to make any investment decision with respect to the Merger or for any other purpose or to vote for or against the Merger Proposal or the Share Issuance Proposal, as applicable. The parties’ projections were, in general, prepared solely for internal use and are subjective in many respects and thus subject to interpretation. While presented with numerical specificity, the parties’ projections are estimates of future performance and not historical facts. The parties’ projections reflect numerous assumptions and estimates that the parties preparing such projections made in good faith at the time such projections were prepared with respect to industry performance, general business, economic, regulatory, market and financial conditions and other future events, as well as matters specific to the applicable party. These assumptions are inherently uncertain, were made as of the date the parties’ projections were prepared, and may not be reflective of actual results, either since the date such projections were prepared, now or in the future, in light of changed circumstances, economic conditions, or other developments. Realization of such assumptions is inherently uncertain and may be beyond the control of Finisar,II-VI or their respective subsidiaries. Some or all of the assumptions that have been made regarding, among other

127

things, the timing of certain occurrences or impacts, may have changed since the date the parties’ projections were prepared. The parties’ projections were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of Finisar orII-VI, as applicable. The inclusion of the parties’ projections in this joint proxy statement/prospectus should not be regarded as an indication that the boards of directors of Finisar orII-VI, advisors of Finisar orII-VI or any other person considered, or now considers, such projections to be material or to be a reliable prediction of actual results, and such projections should not be relied upon as such.

Important factors that may affect actual results and cause the parties’ projections not to be achieved include risks and uncertainties relating to Finisar’s andII-VI’s businesses (including their abilities to achieve their respective strategic goals, objectives and targets over applicable periods, industry conditions, the legal and regulatory environment, general business and economic conditions and other factors described under “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” beginning on pages 48 and 62, respectively, of this joint proxy statement/prospectus, as well as the risk factors with respect to Finisar’s andII-VI’s respective businesses contained in their most recent SEC filings, which you are urged to review, which may be found as described under “Where You Can Find More Information” beginning on page 223 of this joint proxy statement/prospectus). In the view of Finisar’s management, the Finisar management projections were prepared on a reasonable basis based on the information available to Finisar’s management at the time of their preparation. In addition, the parties’ projections cover multiple future years, and such information by its nature is less reliable in predicting each successive year. The parties’ projections also do not take into account any circumstances or events occurring after the date on which they were prepared, and do not give effect to the transactions contemplated by the Merger Agreement, including the Merger. The parties’ projections also reflect assumptions as to certain business decisions that are subject to change. As a result, actual results may differ materially from those contained in the parties’ projections. Accordingly, there can be no assurance that the parties’ projections will be realized or that actual results will not be significantly higher or lower than projected.

The parties’ projections were not prepared with a view toward complying with GAAP (including because certain metrics arenon-GAAP measures as discussed above), the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither Finisar’s norII-VI’s independent registered public accounting firm, nor any other independent accountants, have compiled, examined, reviewed, audited, applied or performed any procedures with respect to either party’s projections, nor has any of them expressed any opinion or any other form of assurance on either party’s projections or the achievability of the results reflected in either party’s projections, and none of them assumes any responsibility for, and each of them disclaims any association with, either party’s projections. The reports of Finisar’s andII-VI’s independent registered public accounting firms incorporated by reference into this joint proxy statement/prospectus relate to Finisar’s andII-VI’s historical financial information, respectively, and no such report extends to either party’s projections or should be read to do so. The parties’ projections includenon-GAAP financial measures.

The inclusion of the parties’ respective projections in this joint proxy statement/prospectus should not be regarded as an indication that any of Finisar,II-VI or their respective affiliates, officers, directors, employees, advisors or other representatives considered either party’s projections to be predictive of actual future events, and the parties’ respective projections should not be relied on as such. None of Finisar,II-VI or their respective affiliates, officers, employees, directors, advisors or other representatives can give you any assurance that actual results will not differ from the parties’ respective projections, and none of Finisar,II-VI or their respective affiliates, officers, employees or directors undertakes any obligation to update or otherwise revise or reconcile either party’s projections to reflect circumstances existing after the date the parties’ respective projections were prepared or to reflect the occurrence of future events even in the event that any or all of the assumptions underlying the parties’ respective projections are not realized, shown to be in error or not be appropriate. Neither Finisar norII-VI intends to publicly update or make any other revision to either party’s projections. None of Finisar,II-VI or any of their respective affiliates, officers, employees, directors, advisors or other representatives has made or makes any representation to any Finisar stockholder,II-VI shareholder or any other person regarding

128

Finisar’s orII-VI’s ultimate performance compared to either party’s projections or that the results reflected therein will be achieved. Neither Finisar norII-VI has made any representation to the other, in the Merger Agreement or otherwise, concerning the parties’ respective projections. For the reasons described above, readers of this joint proxy statement/prospectus are cautioned not to place undue, if any, reliance on either party’s projections.

Regulatory Approvals

General

Each ofII-VI and Finisar has agreed to use its reasonable best efforts to cause the closing of the Merger to occur, which “reasonable best efforts” ofII-VI include promptly opposing any motion or action for an injunction against the Merger, including any legislative, administrative or judicial action, and taking all steps necessary to have vacated, lifted, reversed, overturned, avoided, eliminated or removed any decree, judgment, injunction or other order that restricts, prevents or prohibits the consummation of the Merger or any other transactions contemplated by the Merger Agreement under the HSR Act, or other federal, state, local or foreign antitrust, competition, premerger notification or trade regulation laws, regulations or orders; provided that such efforts shall not requireII-VI to make certain divestitures or agree to make certain divestitures or other limitations or take any other action that, individually or in the aggregate, would have a material adverse effect onII-VI and Finisar, taken as a whole, after the consummation of the transactions. See “The Merger Agreement — Efforts to Complete the Merger” beginning on page 155 of this joint proxy statement/prospectus.

The obligation of each ofII-VI and Finisar to effect the Merger is conditioned upon, among other things, (i) the expiration or early termination of the waiting period under the HSR Act relating opt the transactions contemplated by the Merger Agreement and (ii) receipt of all other consents, approvals, licenses, permits, certificates, orders or authorizations of any governmental authority under certain specified federal, state, local or foreign antitrust, competition, premerger notification or trade regulation laws, regulations or orders. See “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 160 of this joint proxy statement/prospectus.

Department of Justice, Federal Trade Commission and Other U.S. Antitrust Authorities

Under the HSR Act, certain transactions, including the Merger, may not be completed unless certain waiting period requirements have expired or been terminated. The HSR Act provides that each party must file apre-merger notification with the FTC and the DOJ. A transaction notifiable under the HSR Act may not be completed until the expiration of a30-calendar-day waiting period following the parties’ filings of their respective HSR Act notification forms or the early termination of that waiting period. II-VI and Finisar have made the requisite filings.

At any time before or after the Merger is completed, the FTC or DOJ could take action under the antitrust laws in opposition to the Merger, including seeking to enjoin completion of the Merger, condition approval of the Merger upon the divestiture of assets ofII-VI, Finisar or their respective subsidiaries or impose restrictions onII-VI’s post-Merger operations. In addition, U.S. state attorneys general could take such action under the antitrust laws as they deem necessary or desirable in the public interest including, without limitation, seeking to enjoin completion of the Merger or permitting completion subject to regulatory concessions or conditions. Private parties also may seek to take legal action under the antitrust laws under some circumstances.

The State Administration for Market Regulation in China

Under the Anti-monopoly Law of the People’s Republic of China of 2008 (as amended), transactions involving parties with sales above certain revenue levels cannot be completed until they are reviewed and approved by the State Administration for Market Regulation in China (“SAMR”).II-VI and Finisar have sufficient revenues in China to exceed the statutory thresholds, and completion of the Merger is therefore conditioned upon SAMR approval. II-VI and Finisar have made the requisite filing.

129

The Federal Cartel Office of the Federal Republic of Germany

Under the German Act against Restraints of Competition of 1958(Gesetz gegen Wettbewerbsbeschränkungen) (as amended), transactions involving parties with sales above certain revenue levels cannot be completed until they are either reviewed and approved by the Federal Cartel Office of the Federal Republic of Germany (“FCO”) or the relevant waiting periods have expired without the FCO having prohibited the Merger.II-VI and Finisar have sufficient revenues in Germany to exceed the statutory thresholds, and completion of the Merger is therefore conditioned upon either FCO approval or the expiration of the relevant waiting periods. II-VI and Finisar have made the requisite filing, which has been approved by the FCO.

The Mexican Federal Economic Competition Commission

Under the Mexican Federal Economic Competition Law of 2014(Ley Federal de Competencia Económica) and its regulations(Disposiciones Regulatorias de la Ley Federal de Competencia Económica), transactions involving parties with sales above certain revenue levels cannot be completed until they are reviewed and approved by the Mexican Federal Economic Competition Commission (“COFECE”).II-VI and Finisar have sufficient revenues in Mexico to exceed the statutory thresholds, and completion of the Merger is therefore conditioned upon COFECE approval. II-VI and Finisar have made the requisite filing.

The Romanian Competition Council

Under the Romanian Competition Law no. 21/1996(Lege nr. 21 din 10 aprilie 1996 a Concurenţei — Republicare) (as amended) and Regulation on Economic Concentrations approved by Romanian Competition Council Order No. 431/2017(Ordinul nr. 431/2017 pentru punerea în aplicare a Regulamentului privind concentrările economice), transactions involving parties with sales above certain revenue levels cannot be completed until they are reviewed and approved by the Romanian Competition Council (“RCC”).II-VI and Finisar have sufficient revenues in Romania to exceed the statutory thresholds, and completion of the Merger is therefore conditioned upon RCC approval. II-VI and Finisar have made the requisite filing.

Other Governmental Approvals

NeitherII-VI nor Finisar is aware of any material governmental approvals or actions that are required for completion of the Merger other than those described above. It is presently contemplated that if any such additional material governmental approvals or actions are required, those approvals or actions will be sought.

Timing; Challenges by Governmental and Other Entities

There can be no assurance that any of the regulatory approvals described above will be obtained and, if obtained, there can be no assurance as to the timing of any approvals, the ability to obtain the approvals on satisfactory terms or the absence of any litigation challenging such approvals. In addition, there can be no assurance that any of the governmental or other entities described above, including the DOJ, U.S. state attorneys general, state insurance regulators and private parties, will not challenge the Merger on antitrust or competition grounds and, if such a challenge is made, there can be no assurance as to its result.

Listing ofII-VI Common Stock; Delisting and Deregistration of Finisar Common Stock

II-VI will file a notification of listing of additional shares (or such other form as may be required) with the Nasdaq Global Select Market, whereII-VI Common Stock current is traded, with respect to the shares ofII-VI Common Stock to be issued in the Merger and cause such shares to be reserved for issuance to be approved for listing on the Nasdaq Global Select Market.

If the Merger is completed, Finisar Common Stock will be delisted from the Nasdaq Global Select Market and deregistered under the Exchange Act, and Finisar will no longer be required to file periodic reports with the SEC in respect of the Finisar Common Stock. Prior to the closing of the Merger, Finisar has agreed to cooperate withII-VI and use its commercially reasonable efforts to cause such delisting and deregistration.

130

Appraisal Rights for Finisar Stockholders

Pursuant to Section 262 of the DGCL, a Finisar stockholder who chooses the Stock Election Consideration for his, her or its shares of Finisar Common Stock, but receives cash andII-VI Common Stock for such shares through the proration adjustment mechanism due to an oversubscription of the Stock Election Consideration, will be entitled to appraisal rights for such shares if such stockholder otherwise complies with the requirements of Section 262 of the DGCL.APPRAISAL RIGHTS WILLNOT BE AVAILABLE TO FINISARSTOCKHOLDERS WHO FAIL TO MAKE AN ELECTION AND RECEIVE THE MIXED ELECTION CONSIDERATION OR TO FINISAR STOCKHOLDERS WHO CHOOSE THE CASH ELECTION CONSIDERATION OR THE MIXED ELECTION CONSIDERATION. THE ONLY CIRCUMSTANCES IN WHICH A FINISAR STOCKHOLDER MAY BE ENTITLED TO APPRAISAL RIGHTS IS IF SUCH STOCKHOLDER CHOOSES THE STOCK ELECTION CONSIDERATION BUT RECEIVES A COMBINATION OF CASH AND SHARES OFII-VI COMMON STOCK THROUGH THE PRORATION MECHANISMS. Finisar stockholders who are entitled to appraisal rights and wish to exercise the right to seek an appraisal of their shares must not vote in favor of the Merger Proposal nor consent thereto in writing, must continuously hold their shares of Finisar Common Stock through the effective date of the Merger, must deliver to Finisar a written demand for appraisal prior to the date of the Finisar Special Meeting and must otherwise comply with the applicable requirements of Section 262 of the DGCL. The appraisal remedy is the right to seek appraisal of the fair value of shares of Finisar Common Stock, as determined by the Delaware Court of Chancery, if the Merger is completed. The “fair value” of shares of Finisar Common Stock as determined by the Delaware Court of Chancery could be greater than, the same as, or less than the value of the Merger Consideration that Finisar stockholders would otherwise be entitled to receive under the terms of the Merger Agreement.

The right to seek appraisal will be lost if a Finisar stockholder votes “FOR” the Merger Proposal. However, abstaining or voting against the Merger Proposal is not in itself sufficient to perfect appraisal rights because additional actions must also be taken to perfect such rights.

Finisar stockholders who wish to exercise the right to seek an appraisal of their shares must so advise Finisar by submitting a written demand for appraisal prior to the taking of the vote on the Merger Proposal at the Finisar Special Meeting, and must otherwise follow the procedures prescribed by Section 262 of the DGCL. These procedures are summarized in the section entitled “Appraisal Rights” beginning on page 215 of this joint proxy statement/prospectus. A person having a beneficial interest in shares of Finisar Common Stock held of record in the name of another person, such as a nominee or intermediary, must act promptly to cause the record holder to follow the steps required by Section 262 of the DGCL and in a timely manner to perfect appraisal rights. In view of the complexity of Section 262 of the DGCL, Finisar stockholders that may wish to pursue appraisal rights are urged to consult their legal and financial advisors. However, notwithstanding a Finisar stockholder’s compliance with the DGCL, in perfecting appraisal rights, under Section 262 of the DGCL, assuming Finisar Common Stock remains listed on a national securities exchange immediately prior to the Effective Time, the Delaware Court of Chancery will dismiss any appraisal proceedings as to all stockholders who are otherwise entitled to appraisal rights unless (i) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of Finisar Common Stock, or (ii) the value of the consideration provided in the Merger for the total number of shares of Finisar Common Stock entitled to appraisal exceeds $1 million.

No Appraisal or Dissenters’ Rights forII-VI Shareholders

Under Pennsylvania law, as well as the governing documents ofII-VI,II-VI shareholders are not entitled to appraisal or dissenters’ rights in connection with the Merger.

131

Material U.S. Federal Income Tax Consequences

General

The following summary discusses the material U.S. federal income tax consequences of the Merger to holders of shares of Finisar Common Stock. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), applicable Treasury regulations promulgated under the Code, administrative interpretations, and judicial decisions as in effect as of the date of this joint proxy statement/prospectus, all of which may change, possibly with retroactive effect.

This discussion addresses only the consequences of the exchange of shares of Finisar Common Stock held as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). It does not address all aspects of U.S. federal income taxation that may be important to a Finisar stockholder in light of the Finisar stockholder’s particular circumstances, or to a Finisar stockholder that is subject to special rules, such as:

• a bank, thrift, insurance company, or other financial institution;

• a mutual fund;

• atax-exempt organization;

• a dealer or broker in securities;

• a trader in securities that elects to use amark-to-market method of accounting;

• a person whose functional currency is not the U.S. dollar;

• certain former citizens or residents of the United States;

• a real estate investment trust or regulated investment company;

• a Finisar stockholder that holds its shares of Finisar Common Stock through individual retirement or othertax-deferred accounts;

• a Finisar stockholder that holds shares of Finisar Common Stock as part of a hedge, appreciated financial position, constructive sale, straddle, or conversion or integrated transaction;

• a Finisar stockholder that acquired shares of Finisar Common Stock through the exercise of compensatory stock options or stock purchase plans or otherwise as compensation;

• a “controlled foreign corporation,” “passive foreign investment company,” or corporation that accumulates earnings to avoid U.S. federal income tax; or

• a person that is required to report income no later than when such income is reported on an “applicable financial statement.”

For purposes of this discussion, a “U.S. holder” means a beneficial owner of Finisar Common Stock that is for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States;

• a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any state therein or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust that (i) is subject to the primary supervision of a court within the United States and all the substantial decisions of which are controlled by one or more U.S. persons or (ii) has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

A“non-U.S. holder” means a beneficial owner of Finisar Common Stock that is neither a U.S. holder nor a partnership for U.S. federal income tax purposes.

132

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds shares of Finisar Common Stock, the U.S. federal income tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A partnership holding shares of Finisar Common Stock and a partner in such partnership should consult their tax advisor regarding the U.S. federal income tax consequences to them resulting from the Merger.

This discussion of material U.S. federal income tax consequences does not provide a complete analysis of all potential tax consequences of the Merger. This discussion does not address tax consequences that may vary with, or are contingent on, individual circumstances. In addition, it does not address any alternative minimum tax, anynon-income tax (including the U.S. federal estate and gift tax laws) or anynon-U.S., state or local tax consequences of the Merger or the potential application of the Medicare contribution tax on net investment income.Accordingly, each Finisar stockholder should consult its tax advisor to determine the particular U.S. federal, state or local ornon-U.S. income or other tax consequences to it of the Merger.

U.S. Federal Income Tax Consequences to U.S. Holders

The receipt of cash,II-VI Common Stock, or both by U.S. holders in connection with the Merger will be a taxable transaction for U.S. federal income tax purposes. In general, for U.S. federal income tax purposes, a U.S. holder will recognize gain or loss in an amount equal to the difference, if any, between (i) the sum of (x) the amount of cash, including cash received in lieu of fractional shares, received in the Merger, and (y) the fair market value of the shares (at the Effective Time) ofII-VI Common Stock received in the Merger (if any), and (ii) such U.S. holder’s adjusted tax basis in its shares of Finisar Common Stock exchanged therefor. A U.S. holder’s adjusted tax basis in Finisar Common Stock generally will equal the price the U.S. holder paid for such shares.

If a U.S. holder’s holding period in the shares of Finisar Common Stock surrendered in the Merger is greater than one year as of the date of the Merger, the gain or loss will be long-term capital gain or loss. Long-term capital gains of certainnon-corporate holders, including individuals, are generally subject to U.S. federal income tax at preferential rates. The deductibility of a capital loss recognized in connection with the Merger is subject to limitations under the Code. If a U.S. holder acquired different blocks of shares of Finisar Common Stock at different times or different prices, such U.S. holder must determine its adjusted tax basis and holding period separately with respect to each block of shares of Finisar Common Stock that it holds.

A U.S. holder’s aggregate tax basis in itsII-VI Common Stock received in the Merger will equal the fair market value of such shares at the Effective Time, and the U.S. holder’s holding period for such shares will begin on the day after the Merger.

U.S. Federal Income Tax Consequences toNon-U.S. Holders

The receipt of cash,II-VI Common Stock, or both bynon-U.S. holders in connection with the Merger generally will not be subject to U.S. federal income tax unless:

• the gain, if any, recognized by thenon-U.S. holder is effectively connected with a trade or business of thenon-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to thenon-U.S. holder’s permanent establishment in the United States);

• thenon-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the Merger and certain other conditions are met; or

• thenon-U.S. holder owned, directly or by attribution, more than 5% of the shares of Finisar Common Stock at any time during the five-year period preceding the Merger, and Finisar is or has been a “U.S. real property holding corporation” within the meaning of Section 897(c)(2) of the Code for U.S. federal income tax purposes at any time during the shorter of the five-year period preceding the Merger or the period that thenon-U.S. holder held the shares of Finisar Common Stock.

133

Gain described in the first bullet point above will be subject to tax on a net income basis in the same manner as if thenon-U.S. holder were a U.S. holder (unless an applicable income tax treaty provides otherwise). Additionally, any gain described in the first bullet point above of anon-U.S. holder that is a corporation also may be subject to an additional “branch profits tax” at a 30% rate (or lower rate provided by an applicable income tax treaty). Anon-U.S. holder described in the second bullet point above will be subject to tax at a rate of 30% (or a lower rate provided by an applicable income tax treaty) on any capital gain realized, which may be offset by U.S.-source capital losses recognized in the same taxable year. If the third bullet point above applies to anon-U.S. holder, capital gain recognized by such holder will be subject to tax at generally applicable U.S. federal income tax rates. Finisar believes that it has not been a “U.S. real property holding corporation” for U.S. federal income tax purposes at any time during the five-year period preceding the Merger.

Backup Withholding and Information Reporting

Payments made in exchange for shares of Finisar Common Stock (including cash paid in lieu of fractional shares) in connection with the Merger may be subject, under certain circumstances, to information reporting and backup withholding (currently at a rate of 24%). To avoid backup withholding, a U.S. holder that does not otherwise establish an exemption should complete and return an Internal Revenue Service (“IRS”) FormW-9, certifying under penalties of perjury that such U.S. holder is a “United States person” (within the meaning of the Code), that the taxpayer identification number provided is correct and that such U.S. holder is not subject to backup withholding.

Anon-U.S. holder may be subject to information reporting and backup withholding (currently at a rate of 24%) in connection with payments (including cash paid in lieu of fractional shares) made in exchange for shares of Finisar Common Stock unless thenon-U.S. holder establishes an exemption, for example, by completing the appropriate IRS FormW-8 for thenon-U.S. holder, in accordance with the instructions thereto.

Any amount withheld under the backup withholding rules will be allowed as a refund or credit against the U.S. federal income tax liability of a Finisar stockholder, provided the required information is timely furnished to the IRS. The IRS may impose a penalty upon a Finisar stockholder that fails to provide the correct taxpayer identification number.

FATCA

Pursuant to Sections 1471 through 1474 of the Code and related U.S. Treasury guidance commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”), foreign financial institutions (which include most foreign hedge funds, private equity funds, mutual funds, securitization vehicles and any other investment vehicles) and certain other foreign entities generally must comply with information reporting rules and due diligence requirements with respect to their U.S. account holders and investors or be subject to a withholding tax on U.S.-source payments made to them (whether received as a beneficial owner or as an intermediary for another party). A foreign financial institution or other foreign entity that does not comply with the FATCA reporting requirements and due diligence will generally be subject to a 30% withholding tax with respect to any “withholdable payments.” For this purpose, withholdable payments generally include U.S.-source payments otherwise subject to nonresident withholding tax (e.g., U.S.-source dividends). The FATCA withholding tax will apply even if the payment would otherwise not be subject to U.S. nonresident withholding tax (e.g., because it is capital gain). Proposed regulations eliminate this withholding obligation with respect to gross proceeds from dispositions of U.S. common stock.

If FATCA withholding is imposed, a beneficial owner (other than certain foreign financial institutions) generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return and, in the case of anon-financial foreign entity, providing the IRS with certain information regarding its substantial U.S. owners (unless an exception applies).Non-U.S. holders are urged to consult with their own tax advisors regarding the effect, if any, of the FATCA provisions to them based on their particular circumstances.

Accounting Treatment of the Merger

In accordance with GAAP,II-VI will account for the Merger using the acquisition method of accounting, withII-VI being considered the acquirer of Finisar for accounting purposes. This means thatII-VI will allocate the purchase price to the fair value of Finisar tangible and intangible assets and liabilities at the acquisition date, with the excess purchase price, if any, being recorded as goodwill. Under the acquisition method of accounting, goodwill is not amortized but is tested for impairment at least annually. The operating results of Finisar will be reported as part of the combined company beginning on the closing date of the Merger. The final valuation of the tangible and identifiable intangible assets acquired and liabilities assumed has not yet been completed. The completion of the valuation upon consummation of the Merger could result in significantly different amortization expenses and balance sheet classifications than those presented inII-VI’s unaudited pro forma condensed combined financial information included in this joint proxy statement/prospectus

Description of Debt Financing

On November 8, 2018, in connection with its entry into the Merger Agreement,II-VI entered into the Commitment Letter, which was subsequently amended and restated on December 7, 2018 and on December 14, 2018. Subject to the terms and conditions set forth in the Commitment Letter, the Lending Parties have severally committed to provide 100% of up to $2.425 billion in aggregate principal amount of theII-VI Senior Credit Facilities, comprised of (i) a “term a” loan facility of up to $1.0 billion, a portion of which will be available after the closing of the Merger on a delayed draw basis, (ii) a “term b” loan facility of up to $975.0 million and (iii) a revolving credit facility of up to $450.0 million.II-VI currently intends to pay the cash portion of the aggregate Merger Consideration and pay related fees and expenses in connection with the Merger using the proceeds of draws under theII-VI Senior Credit Facilities and cash and short-term investments ofII-VI and Finisar.II-VI currently does not intend to draw on the revolving credit facility in order to fund the cash portion of the aggregate Merger Consideration.

The Lead Arrangers’ obligation to provide the debt financing under the Commitment Letter is subject to customary conditions, including, without limitation, the following (subject to certain exceptions and qualifications as set forth in the Commitment Letter):

• the execution and delivery by all parties thereto of definitive documentation with respect to theII-VI Senior Credit Facilities;

• a substantially concurrent closing of the Merger with the closing under theII-VI Senior Credit Facilities;

• the receipt by the Lead Arrangers of certain specified financial statements ofII-VI and Finisar; and

• the accuracy (subject to materiality standards set forth in the Commitment Letter) of certain specified representations and warranties in the Merger Agreement and in the definitive documents with respect to theII-VI Senior Credit Facilities.

The commitments of the Lead Arrangers with respect to theII-VI Senior Credit Facilities will automatically terminate at 11:59 p.m., New York City time, on the first to occur of (i) November 8, 2019 (unless the Merger occurs on or prior thereto), (ii) the date of closing of the Merger without the use of proceeds from theII-VI Senior Credit Facilities or (iii) the date on whichII-VI delivers written notice to terminate its obligations under the Merger Agreement pursuant to the terms thereof or the date that the Merger Agreement is terminated.

The documentation governing theII-VI Senior Credit Facilities has not been finalized and, accordingly, the actual terms of theII-VI Senior Credit Facilities may differ from those described herein or in the Commitment Letter as a result of the syndication process. Although the debt financing described in this joint proxy statement/prospectus is not subject to a due diligence or “market out,” such financing may not be considered assured. The obligation of the Lead Arrangers to provide the debt financing under the Commitment Letter is subject to a

135

number of conditions. There is a risk that these conditions will not be satisfied and theII-VI Senior Credit Facilities may not be funded when required or at all. As of the date of this joint proxy statement/prospectus, no alternative financing arrangements have been made in the event theII-VI Senior Credit Facilities are not available, and any such alternative financing arrangements may not be available on acceptable terms, or at all, if theII-VI Senior Credit Facilities are not consummated.

Treatment of Finisar Convertible Notes

As of the date of this joint proxy statement/prospectus, Finisar has outstanding approximately $1.1 million aggregate principal amount of 2033 Notes and $575.0 million aggregate principal amount of 2036 Notes.

At the consummation of the Merger and pursuant to the Indentures,II-VI, the Surviving Corporation and the Trustee will enter into supplemental indentures to the Indentures. The respective supplemental indentures will comply with the applicable terms of the Indentures and will, among other things, provide that (y) at and after the Effective Time, the right to convert each $1,000 principal amount of the applicable Finisar Convertible Notes will be changed into a right to convert such principal amount of the applicable Finisar Convertible Notes into the weighted average of the types and amounts of consideration received by holders of Finisar Common Stock that affirmatively make an election to receive Cash Election Consideration, Stock Election Consideration or Mixed Election Consideration that a holder of a number of shares of Finisar Common Stock equal to the applicable conversion rate immediately prior to the consummation of the Merger would have owned or been entitled to receive in connection with the Merger (the “Reference Property”) and(z) II-VI fully and unconditionally guarantees, on a senior unsecured basis, the Finisar Convertible Notes.

Pursuant to the terms of the Indentures, consummation of the Merger will constitute a “Fundamental Change” and a “Make Whole Fundamental Change.” As a result, pursuant, and subject, to the terms and conditions of the Indentures, each holder of Finisar Convertible Notes will have the right, at such holder’s option, to require Finisar (or its successor) to repurchase, at a price equal to 100% of the principal amount thereof, together with accrued and unpaid interest to, but excluding, the repurchase date (the “Merger Repurchase Date”), any or all of such holder’s Finisar Convertible Notes on the date specified by Finisar that is not less than 20 business days and not more than 35 business days after the date of Finisar’s notice of consummation of the Merger delivered to holders of Finisar Convertible Notes pursuant to the terms of the Indentures (the “Fundamental Change Notice”). The Fundamental Change Notice must be delivered on or before the 20th business day after the Effective Time. Alternatively, pursuant, and subject, to the terms and conditions of the Indentures, all or any portion of a holder’s Finisar Convertible Notes may be surrendered for conversion at any time from or after the date that is 25 scheduled trading days prior to the anticipated effective date of the Merger (or, if later, the business day after Finisar provides the notice of the effective date of the Merger) until (i) with respect to the 2033 Notes, the earlier of the redemption date discussed below and the Merger Repurchase Date and (ii) with respect to the 2036 Notes, the Merger Repurchase Date. Pursuant to the terms of the 2036 Notes Indenture, if a holder of 2036 Notes elects to convert its 2036 Notes in connection with the consummation of the Merger, then, pursuant, and subject, to the terms and conditions of the 2036 Notes Indenture, the conversion rate may be increased on such 2036 Notes.

Because the consummation of the Merger will constitute a “Fundamental Change” and a “Make Whole Fundamental Change” pursuant to the terms of the Indentures, holders of the Finisar Convertible Notes will be permitted to choose, pursuant, and subject, to the terms and conditions of the Indentures (i) to convert their Finisar Convertible Notes, (ii) to require Finisar to repurchase their Finisar Convertible Notes for a price equal to 100% of their principal amount, together with accrued and unpaid interest to, but excluding, the repurchase date, or (iii) to continue holding their Finisar Convertible Notes until maturity or until they are otherwise redeemed, repurchased, or converted pursuant to the terms of the applicable Indenture. NeitherII-VI, Merger Sub, Finisar nor any of their respective affiliates or representatives have made, or intend to make, any recommendation to any holder of Finisar Convertible Notes regarding this election.

136

In addition, the 2033 Notes Indenture provides that at any time on or after December 22, 2018, Finisar may elect to redeem, in whole or in part, the outstanding 2033 Notes; provided, however, that a holder of 2033 Notes that are called for redemption that are also convertible pursuant to the terms and conditions of the 2033 Notes Indenture may, subject to the terms and conditions of the 2033 Notes Indenture, surrender those 2033 Notes for conversion at any time prior to the close of business on the business day preceding the redemption date. In the event any 2033 Notes are not otherwise redeemed, repurchased, or converted pursuant to the terms of the 2033 Notes Indenture prior to the consummation of the Merger,II-VI plans to cause the redemption of all 2033 Notes that are outstanding upon the consummation of the Merger in accordance with the terms of the 2033 Notes Indenture and any applicable supplemental indenture as promptly as practicable following the consummation of the Merger. Accordingly,II-VI expects that all such outstanding 2033 Notes will be redeemed on or about the 20th day following the consummation of the Merger.

The 2036 Notes Indenture provides that, other than in connection with a “Fundamental Change” as described above, holders of the 2036 Notes do not have an option to require Finisar to repurchase any 2036 Notes held by them until December 15, 2021. Finisar does not have an option to redeem, in whole or in part, outstanding 2036 Notes until December 22, 2021.

Litigation Relating to the Merger

As of January 17, 2019, six lawsuits have been filed by alleged Finisar stockholders challenging the Merger. The first complaint, a putative class action complaint, was filed by Herbert Hein in the Superior Court of California, County of Santa Clara, and is captionedHein v. Finisar Corporation, et al., 19CV340510. The second complaint, a putative class action complaint, was filed by Pete Tenvold in the United States District Court for the District of Delaware and is captionedTenvold v. Finisar Corporation, et al., 1:19-cv-00050. The third complaint, a putative class action complaint, was filed by Melvyn Klein in the United States District Court for the Northern District of California and is captionedKlein v. Finisar Corporation, et al., 3:19-cv-00155. The fourth complaint, a putative class action complaint, was filed by Earl Wheby, Jr. in the United States District Court for the District of Delaware and is captionedWheby v. Finisar Corporation, et al., 1:19-cv-00064. The fifth complaint was filed by Pankaj Sharma individually in the United States District Court for the Northern District of California and is captionedSharma v. Finisar Corporation, et al.,3:19-cv-00220. The sixth complaint, a putative class action complaint, was filed by William Davis in the United States District Court for the Northern District of California and is captionedDavis v. Finisar Corporation, et al., 3:19-cv-00271.

The complaints name as defendants Finisar and each member of the Finisar Board. In addition, theHein,Tenvold, andKlein complaints name II-VI and Merger Sub as defendants. TheHein,Tenvold,Klein,Wheby, andDavis complaints seek relief on behalf of a putative class defined as all similarly situated Finisar stockholders.

The Heincomplaint alleges that the Finisar Board breached its fiduciary duties to Finisar stockholders by purportedly engaging in an insufficient sales process, obtaining inadequate merger consideration, and filing a materially misleading preliminary proxy statement that does not include, among other things, material information regarding the sales process, financial projections for both Finisar and II-VI, and financial analyses conducted by their financial advisors. TheHein complaint further asserts that II-VI knowingly aided and abetted the Finisar Board in breaching their fiduciary duties to Finisar stockholders by entering into the proposed transaction. TheHeincomplaint seeks preliminary and permanent injunction of the proposed transaction unless the information requested by the plaintiff is disclosed, rescission and unspecified damages if the Merger is consummated, and attorneys’ fees and expert fees and costs.

TheTenvold, Klein, Wheby, Sharma, andDaviscomplaints purport to state claims for violations of Section 14(a) and 20(a) of the Exchange Act and Rule 14a-9 and, in the case of theDavis complaint, Regulation G promulgated thereunder. The plaintiffs in these actions generally allege that the preliminary proxy statement omits material information with respect to the proposed transaction which renders the preliminary proxy statement false and misleading. The plaintiffs in these actions seek an order enjoining the defendants from filing

137

a definitive proxy statement with the SEC or otherwise disseminating a definitive proxy statement to Finisar stockholders or proceeding with closing the Merger unless and until the preliminary proxy statement is cured. In the event the Merger is consummated prior to entry of final judgment, the Tenvold, Klein, Wheby, andSharmacomplaints seek rescission of the Merger or rescissory damages, and theTenvold, Klein, Wheby, Sharma, andDaviscomplaints also seek unspecified damages, attorneys’ and expert fees, and expenses and costs. The defendants believe that the complaints are without merit.

THE MERGER AGREEMENT

This section describes the material terms of the Merger Agreement. The description in this section and elsewhere in this joint proxy statement/prospectus is qualified in its entirety by reference to the complete text of the Merger Agreement, a copy of which is attached asAnnex A and is incorporated by reference into this joint proxy statement/prospectus. This summary does not purport to be complete and may not contain all of the information about the Merger Agreement that is important to you. You are encouraged to read the Merger Agreement carefully and in its entirety. This section is not intended to provide you with any factual information about Finisar orII-VI. Such information can be found elsewhere in this joint proxy statement/prospectus and in the public filings Finisar andII-VI make with the SEC, as described in the section entitled “Where You Can Find More Information” beginning on page 223 of this joint proxy statement/prospectus.

Explanatory Note Regarding Representations, Warranties and Covenants in the Merger Agreement

The Merger Agreement is included to provide you with information regarding its terms. Factual disclosures about Finisar andII-VI contained in this joint proxy statement/prospectus or in the public reports of Finisar andII-VI filed with the SEC may supplement, update or modify the factual disclosures about Finisar andII-VI contained in the Merger Agreement. The representations, warranties and covenants made in the Merger Agreement by Finisar,II-VI and Merger Sub are qualified and subject to important limitations agreed to by Finisar,II-VI and Merger Sub in connection with negotiating the terms of the Merger Agreement. In particular, in your review of the representations and warranties contained in the Merger Agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with a purpose of establishing circumstances in which a party to the Merger Agreement may have the right not to consummate the Merger if the representations and warranties of the other party or parties prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the Merger Agreement, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders or stockholders, as applicable, and reports and documents filed with the SEC and in some cases were qualified by the matters contained in the disclosure letters that Finisar andII-VI each delivered to each other in connection with the Merger Agreement, which disclosures were not reflected in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this joint proxy statement/prospectus, may have changed since the date of the Merger Agreement.

Structure and Effects of the Merger

The Merger Agreement provides for the Merger, in which Merger Sub will be merged with and into Finisar, with Finisar surviving the Merger as a wholly-owned subsidiary ofII-VI. At the Effective Time, the separate corporate existence of Merger Sub will cease, and the Surviving Corporation will continue its corporate existence under the laws of the State of Delaware and succeed to and assume all of the rights and obligations of Finisar and Merger Sub in accordance with the DGCL.

At the Effective Time, all of the property, rights, privileges, immunities, powers and franchises of Finisar and Merger Sub will vest in the Surviving Corporation, and all of the debts, liabilities and duties of Finisar and Merger Sub will become the debts, liabilities and duties of the Surviving Corporation.

At the Effective Time, the certificate of incorporation set forth as Exhibit A to the Merger Agreement and the bylaws set forth on Exhibit B to the Merger Agreement will be the certificate of incorporation and bylaws, respectively, of the Surviving Corporation, in each case, until amended in accordance with applicable law and the certificate of incorporation and bylaws, as applicable. At the Effective Time, the directors of Merger Sub and the officers of Finisar immediately prior to the Effective Time will be the directors and officers, respectively, of the Surviving Corporation, in each case, until their successors are duly elected or appointed and qualified in accordance with the Surviving Corporation’s certificate of incorporation, bylaws and applicable law.

139

The Merger Agreement provides that, at the Effective Time, theII-VI Board will appoint three members of the Finisar Board as of November 8, 2018 to serve on theII-VI Board (the “Finisar Designees”). Each Finisar Designee will be mutually agreed upon byII-VI and Finisar, acting in good faith. In addition, the Corporate Governance and Nominating Committee of theII-VI Board previously will have reasonably approved the appointment of the Finisar Designees to theII-VI Board, which also will have previously recommended the appointment of the Finisar Designees to the fullII-VI Board. The total number of directors on theII-VI Board at the Effective Time will be no more than 11 persons. As of the date hereof, the identity of the Finisar Designees has not been determined byII-VI and Finisar. Also at the Effective Time, theII-VI Board will have four committees, consisting of an Audit Committee, a Compensation Committee, a Subsidiary Committee and a Corporate Governance and Nominating Committee. Each such committee will include at least one Finisar Designee.

Completion and Effectiveness of the Merger

The Merger will be completed and become effective at such time as the certificate of merger for the Merger is duly filed with the Secretary of State of the State of Delaware (or at such later time as agreed to by Finisar andII-VI and specified in the certificate of merger for the Merger). Unless the parties otherwise mutually agree or the Merger Agreement is otherwise terminated pursuant to its terms, completion of the Merger will occur on the second business day following the later of the following:

• the satisfaction or, to the extent permissible under law, waiver of the conditions to the closing of the Merger set forth in the Merger Agreement (other than those conditions that by their terms are to be satisfied at the closing, but subject to the satisfaction or, to the extent permitted by law, waiver of such conditions at such time) described under “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 160 of this joint proxy statement/prospectus; and

• the earlier to occur of (i) any business day during the Marketing Period (as defined in the section entitled “The Merger Agreement — Financing” beginning on page 156 of this joint proxy statement/prospectus) to be specified byII-VI to Finisar on no less than three business days’ prior written notice to Finisar and (ii) the business day following the last day of the Marketing Period, but in each case subject to the satisfaction or, to the extent permitted by applicable law, waiver of the conditions to the closing of the Merger set forth in the Merger Agreement.

As of the date of this joint proxy statement/prospectus,II-VI and Finisar expect that the Merger will be completed approximately in the middle of 2019. However, completion of the Merger is subject to the satisfaction or, to the extent permitted by applicable law, waiver of the conditions to closing of the Merger set forth in the Merger Agreement. There can be no assurances as to when, or if, the Merger will occur. If the Merger is not completed on or before the end date of November 8, 2019, eitherII-VI or Finisar may terminate the Merger Agreement, but such right to terminate the Merger Agreement after the end date will not be available toII-VI or Finisar, as applicable, if that party’s failure to fulfill any of its obligations under the Merger Agreement has been a principal cause of or results in the failure of the Merger to occur by that time. See “The Merger Agreement — Conditions to Completion of the Merger” and “The Merger Agreement — Termination of the Merger Agreement” beginning on pages 160 and 161, respectively, of this joint proxy statement/prospectus.

Merger Consideration

At the Effective Time, each outstanding share of Finisar Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Stockholder Shares and Excluded Shares), will be converted into the right to receive, at the election of the holder of such share of Finisar Common Stock, (a) Cash Election Consideration, consisting of $26.00 in cash, without interest (subject to the proration adjustment procedures described in this joint proxy statement/prospectus), (b) Stock Election Consideration, consisting of 0.5546 validly issued, fully paid andnon-assessable shares ofII-VI Common Stock (subject to the proration adjustment procedures described in this joint proxy statement/prospectus), or (c) Mixed Election Consideration,

140

consisting of $15.60 in cash, without interest, and 0.2218 validly issued, fully paid andnon-assessable shares ofII-VI Common Stock; provided, that Finisar stockholders who are otherwise entitled to receive fractional shares ofII-VI Common Stock as part of the Merger Consideration will receive cash in lieu of such fractional shares ofII-VI Common Stock.

As further described below in the section entitled “The Merger Agreement — Election Procedures” beginning on page 142 of this joint proxy statement/prospectus, and as provided in more detail in the Merger Agreement, holder of record of shares of Finisar Common Stock (not including the Dissenting Stockholder Shares or the Excluded Shares, but including holders of Participating RSUs) will, until the Election Deadline, be entitled to elect to receive either Cash Election Consideration (a “Cash Election”), Stock Election Consideration (a defined above, a “Stock Election”), or Mixed Election Consideration (a “Mixed Election”), in exchange for each share of Finisar Common Stock held by him or her that was issued and outstanding immediately prior to the Effective Time (other than any Excluded Shares) (including with respect to such holder’s Participating RSUs held by such holder prior to the Effective Time), subject to proration procedures described below and in further detail in the Merger Agreement. Holders entitled to make an election that fail to do so or that make an untimely election (or who otherwise are deemed not to have submitted an effective form of election) will be deemed to have elected for Mixed Election Consideration. The Exchange Agent has reasonable discretion to determine whether a Stock Election, Cash Election or Mixed Election has been properly made in respect of any shares of Finisar Common Stock (including with respect to Participating RSUs). For more information regarding the Election Deadline, see the section entitled “The Merger Agreement — Election Procedures” beginning on page 142 of this joint proxy statement/prospectus.

Stock Elections and Cash Elections are subject to the proration adjustment procedures described in this joint proxy statement/prospectus to ensure that the aggregate Merger Consideration will consist of approximately 60% cash and approximately 40%II-VI Common Stock (with theII-VI Common Stock valued at the closing price as of November 8, 2018).

Proration may be applied in certain circumstances, including as follows:

If (i) the product of the number of Cash Electing Sharesmultiplied by the Cash Election Consideration (before giving effect to any proration adjustment) (the “Cash Election Amount”) exceeds (ii) the Available Cash Election Amount, then:

(A) all Stock Electing Shares will be converted into the right to receive the Stock Election Consideration (without further proration);

(B) all Mixed Consideration Shares will be converted into the right to receive the Mixed Election Consideration (without further proration); and

(C) the following consideration will be paid in respect of each Cash Electing Share:

• an amount of cash equal to the quotient of (1) the Available Cash Election Amountdivided by(ii) the number of Cash Electing Shares; and

• a number of shares ofII-VI Common Stock equal to the quotient of (1) the difference of the Available Stock Election Amountless the Stock Election Amountdivided by (2) the number of Cash Electing Shares.

If the Available Cash Election Amount exceeds the Cash Election Amount, then:

(A) all Cash Electing Shares will be converted into the right to receive the Cash Election Consideration (without further proration);

(B) all Mixed Consideration Shares will be converted into the right to receive the Mixed Election Consideration (without further proration); and

141

(C) the following consideration will be paid in respect of each Stock Electing Share:

• an amount of cash equal to the quotient of (1) the difference of the Available Cash Election Amountless the Cash Election Amountdivided by (2) the number of Stock Electing Shares; and

• a number of shares ofII-VI Common Stock equal to the quotient of (1) the Available Stock Election Amountdivided by (2) the number of Stock Electing Shares.

The “Available Cash Election Amount” means (i) the product of $15.60multiplied by the number of total outstanding shares of Finisar Common Stock as of the Effective Time (excluding the Excluded Shares, but including the number of Dissenting Stockholder Shares, Net Option Shares and Participating RSUs)minus (ii) the aggregate amount of cash to be paid in respect of all shares of Finisar Common Stock with respect to which either a Mixed Election was made and not revoked or with respect to which no election was made (together with the Mixed Election RSUs, the “Mixed Consideration Shares”) (assuming that all Dissenting Stockholder Shares and all Net Option Shares are Mixed Consideration Shares).

The “Available Stock Election Amount” means (i) the product of 0.2218multiplied by the number of total outstanding shares of Finisar Common Stock as of the Effective Time (excluding the Excluded Shares, but including the number of Dissenting Stockholder Shares, Net Option Shares and Participating RSUs)minus (ii) the aggregate number of shares ofII-VI Common Stock to be paid in respect of all Mixed Consideration Shares (assuming that all Dissenting Stockholder Shares and all Net Option Shares are Mixed Consideration Shares).

The “Cash Election Amount” means the product of (i) the number of Cash Electing Sharesmultiplied by (ii) the Cash Election Consideration (before giving effect to any proration adjustment pursuant to the Merger Agreement).

The “Stock Election Amount” means the product of (i) the number of Stock Electing Sharesmultiplied by(ii) the Stock Election Consideration (before giving effect to any proration adjustment pursuant to the Merger Agreement).

Election Procedures

II-VI has selected American Stock Transfer and Trust Company to serve as the Exchange Agent to, among other things, handle the exchange of shares of Finisar Common Stock for the Merger Consideration and any cash in lieu of fractional shares, in each case deliverable in respect thereof pursuant to the Merger Agreement.

At least 20 business days prior to the anticipated Election Deadline,II-VI will provide a form of election to each holder of record of shares of Finisar Common Stock (not including the Dissenting Stockholder Shares or the Excluded Shares, but including holders of Participating RSUs) of the procedure for exercising his, her or its right to make an election. To be effective, a form of election must be properly completed, signed and submitted to the Exchange Agent by the Election Deadline. The “Election Deadline” is 5:00 p.m., New York City time, on the date that the parties to the Merger Agreement agree is as near as practicable to two business days preceding the closing date of the Merger. Finisar may waive the Election Deadline so long as it is waived with respect to all holders entitled to make an election of Merger Consideration and the new election deadline is publicly disclosed to all such holders on a date agreed to byII-VI. In any event,II-VI must give its prior written consent to any such waiver.

Any holder entitled to make an election of Merger Consideration may, at any time prior to the Election Deadline, revoke such election by written notice that is sent to and received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed revised form of election. Any holder who has validly revoked his, her or its Merger Consideration election and has not properly submitted a new duly completed form of election will be deemed to have made a Mixed Election. After an election is validly made, any

142

subsequent transfer of shares will automatically revoke such election. The Exchange Agent will determine, in its reasonable discretion, whether any election is not properly made, changed or revoked with respect to any shares of Finisar Common Stock (including with respect to any Participating RSUs).

Exchange Procedures

At or immediately following Effective Time,II-VI will deposit, or cause to be deposited, with the Exchange Agent (i) certificates representing the shares ofII-VI Common Stock to be issued as Stock Election Consideration (or appropriate alternative arrangements will be made byII-VI if uncertificated shares ofII-VI Common Stock will be issued) and (ii) a cash amount in immediately available funds equal to the aggregate Cash Election Consideration (the “Exchange Fund”).

Promptly (but not later than two business days) after the Effective Time,II-VI will cause the Exchange Agent to send a customary letter of transmittal to each holder of record of a certificate representing shares of Finisar Common Stock for use in the exchange for the Merger Consideration, along with instructions for effecting the surrender of the certificates in exchange for the Merger Consideration. Upon surrender of certificates for cancellation to the Exchange Agent, and upon delivery of a letter of transmittal, duly executed and in proper form with respect to such certificates, and such other documents as may reasonably be required, the holder of such certificates will be entitled to receive the Merger Consideration (subject to the type of election with respect to such shares of Finisar Common Stock and after giving effect to any required tax withholdings) and any cash in lieu of fractional shares. Any holder of book-entry shares will, upon receipt by the Exchange Agent of an “agent’s message” (or such other evidence, if any, of surrender as the Exchange Agent may reasonably request) be entitled to receive the Merger Consideration (subject to the type of election with respect to such shares of Finisar Common Stock and after giving effect to any required tax withholdings) and any cash in lieu of fractional shares.

As of the Effective Time, the stock transfer books of Finisar will be closed, and there will be no further registration of transfers on the stock transfer books of Finisar of the shares of Finisar Common Stock that were outstanding as of immediately prior to the Effective Time, other than registrations of transfers to reflect, with customary settlement procedures, trades effected prior to the Effective Time. If, after the Effective Time, certificates or book-entry shares are presented to the Surviving Corporation,II-VI or the Exchange Agent for any reason, they will be cancelled and, subject to the procedures set forth in the Merger Agreement, exchanged as provided in the Merger Agreement, except as otherwise required by law.

Any portion of the Exchange Fund (including any interest or income thereto) that remains undistributed for one year after the Effective Time will be returned to the Surviving Corporation upon its demand, and any holder of Finisar Common Stock who has not complied with the terms of the Merger Agreement relating to the election and exchange procedures for Merger Consideration may thereafter look only to the Surviving Corporation for payment of their claim for the Merger Consideration.

Lost, Stolen or Destroyed Shares

If any certificate for shares of Finisar Common Stock have been lost, stolen or destroyed, then, before a Finisar stockholder will be entitled to receive the Merger Consideration and any cash in lieu of fractional shares and any dividends and distributions on such certificate, in each case deliverable in respect thereof pursuant to the Merger Agreement, such stockholder will need to make an affidavit of that fact and, if required byII-VI, post a bond in such reasonable amount asII-VI may direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such certificate.

Dissenting Shares

Shares of Finisar Common Stock that are issued and outstanding immediately prior to the Effective Time which are held by a Finisar stockholder who has neither voted in favor of the Merger Proposal nor consented

143

thereto in writing and who is entitled to demand, and has properly demanded, appraisal for such shares of Finisar Common Stock in accordance with, and who complies in all respects with, Section 262 of the DGCL (“Dissenting Stockholder Shares”) will not be converted into the right to receive the Merger Consideration. At the Effective Time, all Dissenting Stockholder Shares will instead be canceled and cease to exist, and the holders of Dissenting Stockholder Shares will only be entitled to the rights granted to them under the DGCL. If any such holder of Dissenting Stockholder Shares fails to perfect or otherwise withdraws or loses its right to appraisal under Section 262 of the DGCL, then such Dissenting Stockholder Shares will be deemed to have been converted, as of the Effective Time, into and will be exchangeable solely for the right to receive the Mixed Election Consideration for each such Dissenting Stockholder Share, without interest and subject to any withholding of taxes required by applicable law.

Treatment of Finisar Employee Stock Plans

Stock Options

At the Effective Time, each option granted pursuant to Finisar’s 2005 Stock Incentive Plan (as such plan has been further amended and restated) (each, a “Finisar Stock Option”) (or portion thereof) that is outstanding and unexercised as of immediately prior to the Effective Time (whether vested or unvested) will be cancelled and terminated and converted into the right to receive an amount of Mixed Election Consideration that would be payable to a holder of such number of shares of Finisar Common Stock equal to the quotient of (i) the product of (a) the excess, if any, of $26.00 over the exercise price per share of such Finisar Stock Option multiplied by (b) the number of shares of Finisar Common Stock subject to such Finisar Stock Option,divided by (ii) $26.00 (the “Net Option Shares”).

The payment to each holder of a Finisar Stock Option will be made no later than Finisar’s next payroll date immediately following the closing of the Merger and will be reduced by any applicable tax withholding. The applicable taxes required to be withheld from any such payment will reduce first the cash portion of such payment, with any remaining amount reducing the stock portion of such payment and with the value of any reduction of the stock portion for purposes of such deduction to be determined based on the volume weighted average price per share ofII-VI Common Stock (rounded to the nearest cent) on the Nasdaq Global Select Market for the ten consecutive trading days ending on (and including) the third trading day immediately prior to the Effective Time. At or immediately following the Effective Time,II-VI will deposit, or will cause to be deposited, with Finisar, for the benefit of the holders of Finisar Stock Options, the cash portion of the total Mixed Election Consideration payable with respect to such holders in immediately available funds to be paid through Finisar’s payroll systems.

Each Finisar Stock Option that is outstanding and unexercised as of immediately prior to the Effective Time (whether vested or unvested) with an exercise price per share that is in excess of $26.00 will be cancelled and extinguished at the Effective Time without any present or future right to receive any portion of the Merger Consideration or any other payment.

Restricted Stock Units

As of the Effective Time, each restricted stock unit granted pursuant to Finisar’s 2005 Stock Incentive Plan (as such plan has been further amended and restated) (each, a “Finisar Restricted Stock Unit”) (or portion thereof) that is outstanding and subject to a performance-based vesting condition that relates solely to the value of Finisar Common Stock will, to the extent such Finisar Restricted Stock Unit vests in accordance with its terms in connection with the Merger (the “Participating RSUs”), be cancelled and extinguished and converted into the right to receive the Cash Election Consideration, the Stock Election Consideration or the Mixed Election Consideration at the election of the holder of such Participating RSUs, subject to the proration adjustment procedures described in this joint proxy statement/prospectus (as applicable, the “Cash Election RSUs,” the “Stock Election RSUs” or the “Mixed Election RSUs”).

144

As of the Effective Time, each Finisar Restricted Stock Unit (or portion thereof) that is subject to a performance-based vesting condition that relates solely to the value of Finisar Common Stock but does not vest in accordance with its terms in connection with the Merger will be cancelled and extinguished without any right to receive the Merger Consideration or any other payment.

At the Effective Time, each Finisar Restricted Stock Unit (or portion thereof) that is outstanding and unvested and does not vest in accordance with its terms in connection with the Merger and is either (x) subject to time-based vesting requirements only or (y) subject to a performance-based vesting condition other than the value of Finisar Common Stock will be assumed byII-VI (each, an “Assumed RSU”). Each Assumed RSU will be subject to substantially the same terms and conditions as applied to the related Finisar Restricted Stock Unit immediately prior to the Effective Time, including the vesting schedule (and the applicable performance-vesting conditions in the case of a grant contemplated by clause (y) of the preceding sentence) and any provisions for accelerated vesting applicable thereto, except that the number of shares ofII-VI Common Stock subject to each Assumed RSU will be equal to the product of (i) the number of shares of Finisar Common Stock underlying such unvested Finisar Restricted Stock Unit award as of immediately prior to the Effective Timemultiplied by (ii) the sum of (a) 0.2218plus (b) the quotient obtained by dividing (1) $15.60by (2) the volume weighted average price per share ofII-VI Common Stock (rounded to the nearest cent) on the Nasdaq Global Select Market for the ten (10) consecutive trading days ending on (and including) the third trading day immediately prior to the Effective Time (with the resulting number, rounded down to the nearest whole share). As soon as practicable after the Effective Time,II-VI will deliver to each holder of a Finisar Restricted Stock Unit that will be assumed byII-VI appropriate notices setting forth the number of shares ofII-VI Common Stock subject to each Assumed RSU then held by such holder.

Finisar ESPP

Finisar has agreed to take such action as soon as practicable following the date of the Merger Agreement as may be necessary to: (i) cause any offering period (or similar period during which shares may be purchased) underway as of the date of the Merger Agreement under Finisar’s 2009 Employee Stock Purchase Plan (the “Finisar ESPP”) to be the final offering period under the Finisar ESPP, and the current offering period underway to be terminated no later than the business day immediately preceding the anticipated closing date of the Merger (the “Final Exercise Date”); and (ii) cause each participant’s outstanding purchase right under the Finisar ESPP to be exercised as of the Final Exercise Date. Accordingly, the purchase date for the current offering period under the Finisar ESPP will occur as scheduled in December 2018 and will follow the same guidelines as the prior purchases. No new offering periods will occur under the Finisar ESPP thereafter.

No Solicitation of Alternative Proposals

Finisar has agreed that, from the date of the Merger Agreement until the earlier to occur of the Effective Time and the termination of the Merger Agreement pursuant to its terms, it will not, and will cause its subsidiaries not to, and will use commercially reasonable efforts to cause its and its subsidiaries’ respective representatives not to directly or indirectly:

• solicit, initiate or knowingly encourage or knowingly facilitate any inquiries, offers or the making of any proposal or announcement that constitutes or would reasonably be expected to lead to any Finisar Takeover Proposal (defined below);

• enter into, continue or otherwise participate in any negotiations or discussions with any third party (other thanII-VI, Merger Sub or their respective representatives) regarding any Finisar Takeover Proposal or any inquiry, indication of interest, proposal or offer that would reasonably be expected to lead to a Finisar Takeover Proposal (other than to state that they are not permitted to engage in such discussions or negotiations);

• furnish any nonpublic information regarding Finisar or any of its subsidiaries to any person (other thanII-VI or Merger Sub or their respective representatives) in connection with or in response to any Finisar Takeover Proposal or any inquiry, indication of interest, proposal or offer that would reasonably be expected to lead to a Finisar Takeover Proposal;

151

(other than an acceptable confidentiality agreement under the terms of the Merger Agreement) contemplating or otherwise relating to a Finisar Takeover Proposal.

Notwithstanding the restrictions described above, if, prior to obtaining the requisite stockholder approval in connection with the Merger, Finisar receives an unsolicited, bona fide, written Finisar Takeover Proposal (that is not withdrawn) made after the date of the Merger Agreement that the Finisar Board concludes in good faith, after consultation with its financial advisor and outside legal counsel, constitutes or that such Finisar Takeover Proposal would reasonably be likely to lead to a Finisar Superior Proposal (defined below), then, subject to compliance with the Merger Agreement, Finisar may, directly or indirectly (including through any of its representatives) (i) furnish any information (including nonpublic information) and access relating to Finisar or any of its subsidiaries to, and/or (ii) enter into, engage and/or participate in discussions and/or negotiations with, any person (and such person’s representatives) making such Finisar Takeover Proposal (subject to Finisar’s compliance with its nonsolicitation obligations in the Merger Agreement, the Finisar Board’s conclusion in good faith that, after consultation with its outside legal counsel, the failure to take such actions would be reasonably likely to be inconsistent with its fiduciary duties under applicable law, Finisar’s receipt from such person of an acceptable confidentiality agreement under the terms of the Merger Agreement and Finisar promptly, and, in any event, within forty-eight (48) hours after making available nonpublic information concerning Finisar and its subsidiaries to the person making such Finisar Takeover Proposal, making available toII-VI and its representatives any nonpublic information concerning Finisar and its subsidiaries that is provided to such person or its representatives that was not previously made available toII-VI or its representatives. Finisar must also promptly (and in no event later than forty-eight (48) hours after receipt) notifyII-VI in writing of the initial receipt of any Finisar Takeover Proposal after the date of the Merger Agreement but prior to the earlier of its receipt of the approval of the Merger Proposal and the termination of the Merger Agreement pursuant to its terms, which notice must include the identity of the person making the Finisar Takeover Proposal, the material terms thereof and a copy of any written proposal or definitive agreement relating to the Finisar Takeover Proposal received by Finisar or any of its subsidiaries or any of its or their representatives in connection therewith. Finisar must also keepII-VI reasonably informed of the status and material terms of any such Finisar Takeover Proposal and promptly, but in no event later than forty-eight (48) hours, after receipt of any written material amendment or written proposed amendment of any such Finisar Takeover Proposal, provideII-VI with a copy thereof. In the event any of Finisar’s subsidiaries or representatives takes any action which, if taken by Finisar, would constitute a breach of its nonsolicitation obligations in the Merger Agreement, Finisar will be deemed to have breached such obligation.

A “Finisar Takeover Proposal” means any bona fide proposal, indication of interest or offer from any person or “group” (as defined in or under Section 13(d) of the Exchange Act) relating to (i) any direct or indirect acquisition or purchase of a business that constitutes or generates 25% or more of the net revenues or assets of Finisar and its subsidiaries, taken as a whole or any assets representing 25% or more of the consolidated assets of Finisar and its subsidiaries, taken as a whole, (ii) any direct or indirect acquisition or purchase of 25% or more of any outstanding class of voting or equity securities of Finisar or of any subsidiary of Finisar, (iii) any tender offer or exchange offer that if consummated would result in any person beneficially owning 25% or more of any outstanding class of voting or equity securities of Finisar or any of its subsidiaries, or (iv) any merger, consolidation, business combination, or other similar extraordinary transaction involving Finisar or any of its subsidiaries pursuant to which the holders of Finisar Common Stock immediately preceding such transaction hold, directly or indirectly, less than 75% of the outstanding voting or equity interests in the surviving or resulting entity of such transaction (in each case, other than the Merger).

A “Finisar Superior Proposal” means any written Finisar Takeover Proposal (that is not withdrawn) that the Finisar Board determines in good faith, after consultation with its financial advisor and outside legal counsel, (i) is reasonably likely to be consummated in accordance with its terms, and (ii) if consummated, would be more favorable to Finisar’s stockholders, in their capacities as such, than the Merger from a financial point of view, taking into account all relevant financial, legal, regulatory, financing, certainty and timing of consummation aspects of such Finisar Takeover Proposal (including any changes to the financial or other terms of the Merger

152

Agreement or the Merger proposed in writing byII-VI), except that all of the references to “25%” and “75%” in the definition of “Finisar Takeover Proposal,” will each be deemed to be a reference to “50%” and “50%,” respectively, for purposes of this definition of “Finisar Superior Proposal.”

Change of Finisar Board Recommendation

Finisar has agreed that, from the date of the Merger Agreement until the earlier to occur of the Effective Time and the termination of the Merger Agreement pursuant to its terms, neither the Finisar Board nor any committee thereof will (i) withdraw, amend or modify, or publicly propose to withdraw, amend or modify, the Finisar Board recommendation that Finisar stockholders adopt the Merger Agreement (the “Finisar Board Recommendation”) in a manner adverse toII-VI or (ii) approve, endorse, recommend or otherwise declare advisable (publicly or otherwise) or publicly propose to approve, endorse or recommend, or otherwise declare advisable any Finisar Takeover Proposal. We refer to the actions described in clauses (i) through (ii) of the previous sentence as a “Finisar Change of Recommendation.”

Notwithstanding the restrictions described above, the Finisar Board, at any time before the Finisar stockholders adopt the Merger Agreement, may effect a Finisar Change of Recommendation in response to (i) a written Finisar Takeover Proposal made to or received by Finisar after the date of the Merger Agreement that has not been withdrawn at the time of such determination and such Finisar Takeover Proposal did not result from a breach of Finisar’snon-solicitation obligations or (ii) the occurrence and continuation of a Finisar Intervening Event (defined below), in each case only if the Finisar Board determines in good faith after consultation with its financial advisor and outside legal counsel that failure to take such action would reasonably be likely to constitute a breach of the Finisar Board’s fiduciary duties under applicable law and, only in the case of a Finisar Takeover Proposal, that such Finisar Takeover Proposal constitutes a Finisar Superior Proposal.

In addition, the Finisar Board may not effect a Finisar Change of Recommendation unless:

• Finisar providesII-VI three business days’ (the “Recommendation Change Notice Period”) prior written notice that the Finisar Board intends to take such action (a “Recommendation Change Notice”), which notice will, in the case of a Finisar Takeover Proposal, include the identity of the person making such Finisar Takeover Proposal, the material terms thereof and a copy of any written proposal or definitive agreement relating to such Finisar Takeover Proposal or, in the case of a Finisar Intervening Event, include a reasonable summary of the Finisar Intervening Event;

• during the Recommendation Change Notice Period, Finisar will have discussed and negotiated in good faith withII-VI and its representatives, if requested byII-VI, any adjustments or modifications to the terms of the Merger Agreement or with respect to a new proposal fromII-VI; and

• at the end of the Recommendation Change Notice Period (and any subsequent Recommendation Change Notice Periods), in the case of a Finisar Takeover Proposal, the Finisar Board determines in good faith, after consultation with its financial advisor and outside legal counsel, that (i) such Finisar Takeover Proposal would continue to constitute a Finisar Superior Proposal (assuming the adjustments or modifications to the terms of the Merger Agreement proposed in writing byII-VI were to be given effect) and (ii) that the failure to take such action would reasonably be likely to constitute a breach of its fiduciary duties under applicable law or, in the case of a Finisar Intervening Event,II-VI will not have made a written offer or proposal capable of being accepted by Finisar that the Finisar Board determines in good faith, after consultation with its financial advisor and outside legal counsel, would obviate the need for the Finisar Board to effect such Finisar Change of Recommendation.

Provided, however, that in the case of a Finisar Takeover Proposal, any material revision or amendment to the material terms of a Finisar Superior Proposal (including any change to the pricing or type of consideration thereof), or, in the case of a Finisar Intervening Event, any material change to the status of the Finisar Intervening Event, requires a new Recommendation Change Notice, except that the Recommendation Change Notice Period will be reduced to two (2) business days after the initial Recommendation Change Notice Period.

Change ofII-VI Board Recommendation

Notwithstanding anything in the Merger Agreement to the contrary, theII-VI Board may, prior the approval ofII-VI’s shareholders of the Share Issuance Proposal, withdraw, amend or modify, or publicly propose to withdraw, amend or modify, its recommendation thatII-VI shareholders approve the Share Issuance Proposal in a manner adverse to Finisar in connection with aII-VI Intervening Event (a“II-VI Change of Recommendation”) if (and only if):

• aII-VI Intervening Event (as defined below) has occurred and is continuing;

• theII-VI Board determines in good faith after consultation with its financial advisor and outside legal counsel that failure to take such action would reasonably be likely to constitute a breach of theII-VI Board’s fiduciary duties under applicable law;

• prior to taking such action,II-VI provides Finisar prior written notice equal to the Recommendation Change Notice Period that theII-VI Board intends to take such action (which notice shall include a reasonable summary of theII-VI Intervening Event);

• during the Recommendation Change Notice Period,II-VI will have discussed and negotiated in good faith with Finisar and its representatives, if requested by Finisar, any adjustments or modifications to the terms of the Merger Agreement or with respect to a new proposal from Finisar; and

• at the end of the Recommendation Change Notice Period (and any subsequent Recommendation Change Notice Period), Finisar has not made a written offer or proposal capable of being accepted byII-VI that theII-VI Board determines in good faith, after consultation with its financial advisor and outside legal counsel, would obviate the need for theII-VI Board to effect suchII-VI Change of Recommendation.

A“II-VI Intervening Event” means a change, effect, event, occurrence or development that affects or would be reasonably likely to affect (i) the business, financial condition or continuing results of operations ofII-VI and its subsidiaries, taken as a whole, or (ii) the benefits of the Merger toII-VI or the shareholders ofII-VI, in either case that:

• is material, individually or in the aggregate with any other such changes, effects, events, occurrences or developments, toII-VI and its subsidiaries, taken as a whole, or the shareholders ofII-VI;

• is not known and is not reasonably foreseeable (or the material consequences of which are not known and not reasonably foreseeable) as of the date of the Merger Agreement; and

• does not relate to or involve anyII-VI Takeover Proposal;

provided that (a) in no event will any action taken pursuant to the affirmative covenants relating to regulatory approvals, or the consequences of any such action, constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been aII-VI Intervening Event; (b) in no event will any change, effect, event, occurrence or development that would fall within any of the exceptions to the definition ofII-VI Material Adverse Effect constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been aII-VI Intervening Event; and (c) in no event will certain other limited items agreed upon

154

by the parties set forth in theII-VI disclosure letter to the Merger Agreement constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been aII-VI Intervening Event.

• any direct or indirect acquisition or purchase of 25% or more of any outstanding class of voting or equity securities ofII-VI or of any subsidiary ofII-VI;

Efforts to Complete the Merger

Each ofII-VI and Finisar has agreed to use its reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable under the Merger Agreement and applicable law to consummate and make effective the transactions contemplated by the Merger Agreement, including the Merger, and cause the satisfaction of all conditions to the completion of the Merger on or prior to November 8, 2019, except that:

• II-VI, its subsidiaries and its affiliates are not required to propose, commit, offer to commit or otherwise effect, by undertaking, consent decree, hold separate order or otherwise, to the sale, divestiture, license or disposition of any assets or businesses ofII-VI or its subsidiaries or affiliates or of Finisar or its subsidiaries, or otherwise offer or commit to take any action that limits the freedom of action, ownership or control with respect to, or ability to retain or hold, any of the business, assets, product lines, properties or services ofII-VI or its subsidiaries or affiliates or of Finisar or its subsidiaries, in each case, subject to limited exceptions; and

• obtaining all actions ornon-actions, waivers, consents, approvals, orders and authorizations from governmental authorities, necessary or appropriate to permit the consummation of the Merger and to provide, and cooperate in providing, notices to, and make or file, and cooperate in the making or filing of, registrations, declarations or filings with, third parties required to be provided prior to the Effective Time;

• executing or delivering any additional instruments reasonably necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, the Merger Agreement;

• opposing any motion or action for an injunction against the Merger, including any legislative, administrative or judicial action, and taking any and all steps necessary to have vacated, lifted, reversed, overturned, avoided, eliminated or removed any decree, judgment, injunction or other order that restricts, prevents or prohibits the consummation of the Merger or any other transactions contemplated by the Merger Agreement under any applicable laws; and

• with respect toII-VI, promptly opposing any motion or action for a temporary, preliminary or permanent injunction against the Merger or any portion thereof, including any legislative, administrative or judicial action, and taking any and all steps necessary to have vacated, lifted, reversed, overturned, avoided, eliminated or removed any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) that restricts, prevents or prohibits the consummation of the Merger or any other transactions contemplated by the Merger Agreement under the HSR Act or other applicable antitrust laws.

Financing

Prior to the consummation of the Merger, each ofII-VI and Merger Sub have agreed to use their respective reasonable best efforts to (and to cause their respective subsidiaries to use their reasonable best efforts to):

• take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary to arrange, obtain and consummate the debt financing described in the Commitment Letter on the terms and conditions described therein;

• maintain in full force and effect the debt financing commitment set forth in the Commitment Letter until the consummation of the transactions contemplated by the Merger Agreement and to materially comply with its obligations thereunder;

• negotiate and enter into definitive agreements with respect to, and including as contemplated in, the Commitment Letter on the terms and conditions (including flex provisions, if applicable) contained in the Commitment Letter or, if available, on other terms that are, in the aggregate, not materially less favorable toII-VI than the terms and conditions contained in the Commitment Letter and in any event do not contain Prohibited Terms (defined below);

156

• satisfy (or, if deemed advisable byII-VI, in its sole discretion, seek a waiver of) on a timely basis all conditions to funding in the Commitment Letter (other than any condition where the failure to be so satisfied is a direct result of Finisar’s failure to furnish information required to be furnished by it pursuant to the Merger Agreement);

• comply with its and their obligations under the Commitment Letter in all material respects, not take or fail to take any action that would result in a failure of any of the conditions in the Commitment Letter or in any definitive agreement related to the debt financing contemplated by the Commitment Letter prevent or impede or delay or make less likely the availability of such debt financing;

• fully pay, or cause to be fully paid, all commitment or other fees arising pursuant to the debt financing commitment contemplated by the Commitment Letter as and when they become due; and

• if all conditions to the debt financing commitment contemplated by the Commitment Letter have been satisfied, draw the full amount of the debt financing and cause the debt financing parties to fund the debt financing required to consummate the transactions contemplated by the Merger Agreement upon the terms set forth therein on the closing date of the Merger.

II-VI may not agree to any amendments or modifications to, or grant any waivers of, any condition or other provision under the Commitment Letter without the prior written consent of Finisar to the extent such amendments, modifications or waivers would:

• reduce the aggregate amount of cash proceeds available from the debt financing such that such cash proceeds, together with the financial resources ofII-VI and its affiliates, including cash on hand and the proceeds of loans under existing credit facilities ofII-VI or its subsidiaries on the closing date of the Merger, in the aggregate, are insufficient to fund the amounts required to be paid byII-VI or Merger Sub under the Merger Agreement and the other transactions contemplated by the Merger Agreement;

• impose new or additional conditions or amend, modify or expand existing conditions precedent as compared to those in the Commitment Letter as in effect on the date of the Merger Agreement in each case in a manner that would materially delay or prevent the funding of the debt financing;

• adversely affect the ability ofII-VI to enforce its rights against other parties to the Commitment Letter or the definitive documentation governing theII-VI Senior Credit Facilities as so amended, replaced, supplemented or otherwise modified, relative to the ability ofII-VI to enforce its rights against such other parties to the Commitment Letter as in effect on the date of the Merger Agreement;

• otherwise prevent, or materially impede, impair or delay, the closing of the Merger; or

• affectII-VI’s ability to consummate the transactions contemplated by the Merger Agreement on the terms contemplated by the Merger Agreement (collectively, the “Prohibited Terms”).

II-VI or Merger Sub will give Finisar prompt notice of the receipt of any written notice or other written communication from any debt financing party with respect to any:

• actual or alleged in writing material breach or default, termination or repudiation by any party to the Commitment Letter or any definitive document related to the debt financing or any provisions of the debt financing commitment contemplated by the Commitment Letter or any definitive document related thereto; or

• of any termination, expiration, or waiver, amendment or other modification of the debt financing commitment set forth in the Commitment Letter.

If any portion of the debt financing contemplated by the Commitment Letter becomes unavailable on the terms and conditions contemplated thereby (including flex provisions, if applicable), and such portion is required to fund any portion of the aggregate cash consideration to be paid byII-VI in connection with the Merger and

157

any fees, expenses and other amounts contemplated to be paid byII-VI, Merger Sub or the Surviving Corporation pursuant to the Merger Agreement (taking into account the cash on hand and other proceeds available toII-VI and its subsidiaries),II-VI and Merger Sub will use their reasonable best efforts to arrange and obtain in replacement thereof alternative financing from alternative sources in an amount sufficient to consummate the transactions contemplated by the Merger Agreement on terms that do not contain any Prohibited Terms, it being understood that ifII-VI proceeds with any alternative financing,II-VI will be subject to the same obligations with respect to such alternative financing as set forth in the Merger Agreement with respect to the debt financing; provided, however that if Finisar is then currently seeking specific performance or injunctive relief pursuant to the Merger Agreement to cause the consummation of the Merger, the restriction on including Prohibited Terms in such alternative financing at such time shall not apply.II-VI will deliver to Finisar true, correct and complete copies of all agreements pursuant to which any source has committed to provide such alternative financing.

Any reference to (1) the “debt financing” includes any such alternative financing, (2) the “Commitment Letter” include the commitment letter (including any related exhibits, schedules, annexes, supplements and other related documents) and the corresponding fee letter with respect to any such alternative financing, and (3) the “debt financing parties” includes the financing institutions contemplated to provide any such alternative financing.

The debt financing is not a condition to the consummation of the Merger.

Employee Benefits Matters

II-VI will, and will cause the Surviving Corporation to, provide to each employee of Finisar as of immediately prior to the Effective Time with:

• for a period of 12 months following the Effective Time, a base salary or wage rate, commission and target annual cash incentive opportunity, and severance benefits that are not materially less, in the aggregate, than the base salary or wage rate, commission and target annual cash incentive opportunity, and severance benefits provided to such Finisar employee immediately before the Effective Time; and

From and after the closing of the Merger,II-VI will use commercially reasonable efforts to, or use commercially reasonable efforts to cause the Surviving Corporation or relevant subsidiary to, credit to employees of Finisar as of immediately prior to the Effective Time the amount of vacation time that such employees had accrued under any applicable Finisar employee benefit plan as of the closing of the Merger.

For each health or welfare benefit plan maintained byII-VI, the Surviving Corporation or the relevant subsidiary for the benefit of any employees of Finisar as of immediately prior to the Effective Time,II-VI will use commercially reasonable efforts to (i) cause to be waived any eligibility waiting periods, any evidence of insurability requirements and the application of anypre-existing condition limitations under such plan and (ii) cause each such Finisar employee to be given credit under such plan for all amounts paid by such Finisar

158

employee under any similar Finisar employee benefit plan for the plan year in which the closing of the Merger occurs for purposes of applying deductibles,co-payments andout-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the applicable plan maintained byII-VI, the Surviving Corporation or the relevant subsidiary, as applicable, for such plan year.

Except as provided below, all fees and expenses incurred in connection with the Merger, whether or not the Merger is consummated, the Merger Agreement and the transactions contemplated thereby will be paid by the party incurring such fees or expenses.

Finisar has agreed to payII-VI a termination fee of $105,200,000 if:

• II-VI terminates the Merger Agreement because (i) the Finisar Board fails to include the recommendation that the Finisar stockholders adopt the Merger Proposal in this joint proxy statement/prospectus, (ii) the Finisar Board effects a Finisar Change of Recommendation (whether or not permitted by the Merger Agreement) or (iii) Finisar willfully breaches in any material respect itsnon-solicitation obligations under the Merger Agreement, andII-VI exercises this termination right within the earlier of (1) 15 business days after it obtains actual knowledge of the applicable cause for termination and (2) the day immediately preceding the Finisar Special Meeting; or

• Finisar terminates the Merger Agreement in order to enter into a written definitive agreement with respect to a Finisar Superior Proposal in accordance with terms of the Merger Agreement.

In addition, Finisar has agreed to payII-VI a termination fee of $105,200,000 if both (i) the Merger Agreement is terminated pursuant to its terms:

• byII-VI or Finisar because the Merger is not consummated by November 8, 2019, and Finisar was not entitled to terminate the Merger Agreement as a result of any breach of any of the covenants or agreements or any of the representations or warranties set forth in the Merger Agreement byII-VI or Merger Sub that, individually or in the aggregate, would result in the failure of any of the conditions of either party’s obligations to effect the Merger or of Finisar’s obligations to effect the Merger to be satisfied as if such time were the closing of the Merger;

• byII-VI, in the event of a breach of any of the (i) covenants or agreements or (ii) representations or warranties set forth in the Merger Agreement by Finisar that, in either case, individually or in the aggregate, would result in the failure of any of the conditions of either party’s obligations to effect the Merger or ofII-VI’s obligations to effect the Merger to be satisfied as if such time were the closing of the Merger, and that is not curable prior to November 8, 2019 or, if curable prior to November 8, 2019,

163

is not cured within the earlier of 30 days following written notice to Finisar thereof or November 8, 2019; provided that neitherII-VI nor Merger Sub is then in material breach of any of their respective representations, warranties, covenants or agreements set forth in the Merger Agreement; provided further thatII-VI may not exercise this termination right in respect of any such breach at any time during such 30 day period, if applicable, and at any time after such 30 day period if such breach is cured within such 30 day period; or

• by Finisar orII-VI because the Finisar Special Meeting shall have been held, the Merger Proposal shall have been submitted to the Finisar stockholders for approval at the Finisar Special Meeting, and the Merger Proposal shall not have been adopted;

and (ii) (a) following the execution and delivery of the Merger Agreement and prior to the Finisar Special Meeting (in the case of any termination pursuant to the first or third paragraphs above) or prior to the breach that forms the basis for the termination of the Merger Agreement (in the case of any termination pursuant to the second paragraph above), a Finisar Takeover Proposal is publicly announced or became publicly known (in the case of any termination pursuant to the first or third paragraph above) or is communicated or otherwise known to Finisar (in the case of any termination pursuant to the second paragraph above), (b) at the time of the Finisar Special Meeting (in the case of any termination pursuant to the first or third paragraph above) or at the time of the breach that forms the basis for the termination of the Merger Agreement (in the case of any termination pursuant to the second paragraph above), such Finisar Takeover Proposal shall be pending and not have been withdrawn and (b) within 12 months after such termination Finisar enters into a written definitive agreement providing for the consummation of a Finisar Takeover Proposal or consummates such Finisar Takeover Proposal, except that all references to “25%” and “75%” in the definition of “Finisar Takeover Proposal” shall be substituted with “50%.”

II-VI has agreed to pay Finisar a termination fee of $105,200,000 if (i) Finisar terminates the Merger Agreement because:

• theII-VI Board fails to include the recommendation that theII-VI shareholders adopt the Share Issuance Proposal in this joint proxy statement/prospectus; or

• theII-VI Board has effected aII-VI Change of Recommendation;

and (ii) Finisar exercises this termination right within the earlier of (1) 15 business days after it obtains actual knowledge of the applicable cause for termination and (2) the day immediately preceding theII-VI Special Meeting.

Amendments, Extensions, Waivers and Consents

The Merger Agreement may be amended by the parties at any time prior to the Effective Time if such amendment is in writing and signed by each party to the Merger Agreement, except that (i) after the adoption of the Merger Proposal or Share Issuance Proposal, no amendment may be made that requires further approval of the Finisar stockholders orII-VI shareholders, as applicable, by law or in accordance with the rules of any relevant stock exchange without such approval and (ii) no amendment, modification, waiver or termination of certain provisions of the Merger Agreement may be effected in a manner that is adverse to the debt financing parties without the prior written consent of the arrangers of the debt financing for the purpose of funding the transactions contemplated by the Merger Agreement.

At any time prior to the Effective Time, a party may (i) extend the time for the performance of any of the obligations or other acts of the other party or parties, (ii) waive any breach or inaccuracies in the representations and warranties of the other party or parties contained in the Merger Agreement or in any document delivered pursuant to the Merger Agreement or (iii) waive compliance by the other parties with any of the agreements or conditions contained in the Merger Agreement. Any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of such party.

164

No Third Party Beneficiaries

The Merger Agreement is not intended to confer, and does not confer, on you or any other person, other thanII-VI, Merger Sub and Finisar, any rights or remedies, except (i) the rights to indemnification and continuing maintenance after the completion of the Merger of directors’ and officers’ liability insurance coverage, (ii) after the Effective Time, the rights of former Finisar stockholders, holders of Finisar Restricted Stock Units and holders of Finisar Stock Options to receive the Merger Consideration or such other treatment as provided for pursuant to the terms of the Merger Agreement and (iii)  certain provisions enforceable by the debt financing parties.

Specific Performance

In no event will Finisar or its representatives be entitled to seek specific performance of the Merger Agreement or the debt financing against the debt financing parties.

Governing Law

The Merger Agreement is governed by Delaware law, except all matters relating to the interpretation, construction, validity and enforcement against any of the debt financing parties and each of their respective affiliates, related parties and representatives in any way relating to the Commitment Letter and related fee letters or the performance thereof or the financings contemplated thereby, will, except as expressly provided in the Commitment Letter, be governed by New York law.

165

INTERESTS OF FINISAR’S DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER

In considering the recommendation of the Finisar Board that Finisar stockholders vote to adopt the Merger Agreement, you should be aware that aside from their interests as Finisar stockholders, Finisar’s directors and executive officers have interests in the Merger that may be different from, or in addition to, those of Finisar stockholders generally. Members of the Finisar Board were aware of and considered these interests, among other matters, in evaluating and negotiating the Merger Agreement and the Merger, and in recommending to Finisar stockholders that the Merger Agreement be adopted. For more information see the sections entitled “The Merger — Background of the Merger” and “The Merger — Finisar’s Reasons for the Merger; Recommendations of the Finisar Board.” These interests are described in more detail below, and certain of them are quantified in the narrative below and in the section entitled “Finisar Proposal No. 3 —Non-Binding, Advisory Vote on Merger-Related Compensation for Finisar’s Named Executive Officers — Golden Parachute Compensation” beginning on page 189.

Treatment of Outstanding Finisar Equity Awards

Awards of Finisar Restricted Stock Units that are subject to performance-based vesting requirements (“Performance-Based RSUs” or “PRSUs”), awards of Finisar Restricted Stock Units that vest over time based solely on the holder’s continued service with Finisar (“Time-Based RSUs”), and Finisar Stock Options that are held by Finisar’s executive officers (i.e., Michael Hurlston, Joseph Young, Todd Swanson, Kurt Adzema, Dr. Julie Eng and Christopher Brown) and outstanding immediately prior to the Effective Time will be treated in the same manner as those Finisar equity awards held by other employees of Finisar. This treatment of Finisar equity awards is described below and in the section titled “The Merger Agreement — Treatment of Finisar Employee Stock Plans” beginning on page 144.

• Performance-Based RSUs. At the Effective Time, each award of Performance-Based RSUs that is then outstanding and is subject to a performance-based vesting condition that relates solely to the value of Finisar Common Stock will vest as to a number of shares determined under the terms of the award as described below and will be cancelled and converted into the right to receive the form of Merger Consideration elected by the holder of such Performance-Based RSU award.

Under the terms of these Performance-Based RSU awards, the total number of Finisar Restricted Stock Units subject to the award is allocated equally to 16 quarterly vesting dates commencing on August 5, 2018 and ending May 5, 2022. The number of Finisar Restricted Stock Units that vest on each vesting date (if any) is determined based on the average of the closing prices for Finisar Common Stock during the last ten trading days of the most recently completed fiscal quarter before the vesting date (the “Average Stock Price”) as follows:

Average Stock Price as of Last Day of Prior Fiscal Quarter	Vesting Percentage for PRSUs Allocated to Applicable Vesting Date
Below $22.50	0%
At least $22.50 and Less Than $27.00	33 1/3%
At least $27.00 and Less Than $31.50	66 2/3%
At least $31.50	100%

The $22.50, $27.00 and $31.50 stock price targets represent increases of 25%, 50% and 75%, respectively, over the closing price of Finisar Common Stock on the date the awards were granted (which was $18.00). In addition to the quarterly vesting described above, the Performance-Based RSU awards include an “annualtrue-up” feature so that on the May 5 vesting date for each of 2019, 2020, and 2021, an additional number of Finisar Restricted Stock Units will vest equal to the excess (if any) of (i) the aggregate number of Finisar Restricted Stock Units that would have been vested on that May 5 vesting date and the immediately preceding August 5, November 5 and February 5 vesting dates if the Average Stock Price determined as of each such vesting date had been the same as the Average

166

Stock Price for the May 5 vesting date, over (ii) the aggregate number of Finisar Restricted Stock Units that actually vested on each of those four vesting dates as determined under the table above. The awards also provide for a “finaltrue-up” calculation on the May 5, 2022 vesting date so that an additional number of Finisar Restricted Stock Units will vest on that date equal to the excess (if any) of (i) the aggregate number of Finisar Restricted Stock Units that would have been vested over all 16 vesting dates for the award if the Average Stock Price determined as of each such vesting date had been the same as the Average Stock Price for the May 5, 2022 vesting date, over (ii) the aggregate number of Finisar Restricted Stock Units that actually vested on each of those 16 vesting dates as determined under the table above and the annualtrue-up vesting provisions described above.

In addition, if a change of control of Finisar occurs before May 5, 2022 and while the executive is still employed with Finisar, the Average Stock Price will be calculated for the period of 10 trading days prior to the change in control, and the award will vest on the change in control as to the number of Finisar Restricted Stock Units that would have vested on each of the remaining scheduled vesting dates under the award (taking into account anytrue-up provision that would have applied during that period) based on the greater of that Average Stock Price or $22.50.

Each of the Performance-Based RSU awards held by Finisar’s executive officers is subject to vesting based on Finisar’s stock price as described above. For purposes of quantifying the value of these awards at the Effective Time, Finisar has assumed that the awards would vest upon the closing of the Merger as toone-third of the total number of Finisar Restricted Stock Units subject to the award (i.e., based on aper-share value for Finisar Common Stock of at least $22.50 and less than $27.00). Finisar has also granted a small number of Performance-Based RSU awards that are subject to performance goals other than stock price to employees who are not executive officers. These awards will generally be subject to the same treatment as Time-Based RSU awards described below.

• Time-Based RSUs. At the Effective Time, each award of Time-Based RSUs that is then outstanding and unvested will be assumed byII-VI (each, an “Assumed RSU”) and continue to be subject to substantially the same terms and conditions (including vesting requirements) as in effect immediately prior to the Effective Time, except that the number of shares ofII-VI Common Stock subject to such Assumed RSU will be equal to the product of (i) the number of shares of Finisar Common Stock underlying such unvested Finisar Restricted Stock Unit award as of immediately prior to the Effective Timemultiplied by (ii) the sum of (a) 0.2218plus (b) the quotient obtained by dividing (1) $15.60by (2) the volume weighted average price per share ofII-VI Common Stock (rounded to the nearest cent) on the Nasdaq Global Select Market for the ten (10) consecutive trading days ending on (and including) the third trading day immediately prior to the Effective Time (with the resulting number, rounded down to the nearest whole share). The Assumed RSUs held by Finisar’s executive officers and other participants in the Severance Plan (as defined below) are subject to accelerated vesting in connection with an involuntary termination of the participant’s employment on or within 18 months following a change in control of Finisar as described under “Executive Retention and Severance Plan” below.

• Finisar Stock Options. At the Effective Time, each then-outstanding and unexercised Finisar Stock Option (whether vested or unvested) will automatically be cancelled and converted into the right to receive a payment in the form of Mixed Consideration (as described above under “The Merger Agreement — Merger Consideration”) that would be payable to a holder of such number of shares of Finisar Common Stock equal to the quotient of (i) the product of (a) the excess, if any, of $26.00 over the exercise price per share of such Finisar Stock Option multiplied by (b) the number of shares of Finisar Common Stock subject to such Finisar Stock Option,divided by (ii) $26.00.

Assuming that the Merger was completed onDecember 10, 2018, the estimated aggregate amount that would be payable to Finisar’s executive officers as a group for their Finisar equity awards is as follows (assuming for purposes of this disclosure only that each executive elected to receive the Mixed Consideration): (a) with respect to a total of 149,000 Finisar Performance-Based RSUs, $2,324,400 in cash and 33,048 shares of

167

II-VI Common Stock, (b) with respect to a total of 645,103 Finisar Time-Based RSUs (assuming for these purposes only that each executive’s employment with Finisar was involuntarily terminated at the Effective Time and such awards would fully accelerate pursuant to the Severance Plan described below), $10,063,606 in cash and 143,083 shares ofII-VI Common Stock, and (c) with respect to a total of 771,086 Finisar Stock Options, $1,990,872 in cash and 28,306 shares ofII-VI Common Stock.

Finisar’snon-employee directors hold Finisar Stock Options and Time-Based RSUs that will accelerate immediately prior to the Effective Time. Assuming that the Merger was completed onDecember 10, 2018, the estimated aggregate amount that would be payable to Finisar’snon-employee directors as a group for their Finisar equity awards is as follows (assuming for purposes of this disclosure only that eachnon-employee director elected to receive the Mixed Consideration): (a) with respect to a total of 83,786 Finisar Time-Based RSUs, $1,307,062 in cash and 18,584 shares ofII-VI Common Stock, and (b) with respect to a total of 8,750 Finisar Stock Options, $66,674 in cash and 948 shares ofII-VI Common Stock.

For an estimate of the amounts that would be payable to each of Finisar’s named executive officers (i.e., Michael Hurlston, Joseph Young, Todd Swanson, Kurt Adzema and Dr. Julie Eng) in connection with any acceleration of the Finisar equity awards, see the section entitled “Finisar Proposal No. 3 —Non-Binding, Advisory Vote on Merger-Related Compensation for Finisar’s Named Executive Officers — Golden Parachute Compensation” beginning on page189. The amounts in the preceding paragraphs were determined using theper-share amounts payable to a Finisar stockholder who elected to receive the Mixed Consideration (i.e., $15.60 in cash and 0.2218 shares ofII-VI Common Stock).

Executive Retention and Severance Plan

Finisar’s executive officers, including each of Finisar’s named executive officers, are eligible to participate in the Finisar Executive Retention and Severance Plan (the “Severance Plan”). The Severance Plan provides that if, on or within 18 months after a change in control, an executive’s employment is terminated by Finisar (or its successor) without cause or by the executive for good reason (as the terms “cause” and “good reason” are each defined in the Severance Plan), the executive would be entitled to receive as severance: (a) a payment equal to 24 months of the executive’s base salary; (b) a payment equal to the executive’s target annual bonus amount most recently determined by the Compensation Committee of the Finisar Board; (c) reimbursement of the executive’s premiums for continued health and life insurance coverage for up to 24 months; and (d) full acceleration of the executive’s time-based equity awards granted by Finisar. Any Finisar performance-based equity awards held by the executive will be subject to the provisions of the applicable award agreement. The executive’s vested Finisar Stock Options would generally remain exercisable for one year following the termination date (subject to the maximum term of the Finisar Stock Option).

In each case, the executive’s right to receive severance benefits under the Severance Plan is subject to the executive’s providing a release of claims in favor of Finisar. If the executive would be entitled to benefits under both the Severance Plan and any other arrangement with Finisar, the executive’s benefits under the Severance Plan will be reduced for the benefits provided under the other arrangement.

If an executive’s benefits under the Severance Plan would trigger parachute payment excise taxes, the benefits will either be paid in full and subject to such taxes or reduced to the extent necessary to avoid triggering such taxes, whichever results in a greaterafter-tax benefits to the executive. Participants are not entitled to anygross-up payment under the plan for such excise taxes.

Other Compensation Matters

Under the Merger Agreement, Finisar may pay bonuses for its 2019 fiscal year to its employees (including its executive officers) pursuant to Finisar’s fiscal 2019 bonus plan if the Effective Time has not occurred by the end of the 2019 fiscal year or may paypro-rated bonuses pursuant to the plan if the Effective Time occurs prior

168

to the end of the 2019 fiscal year. In addition, Finisar may adopt a fiscal year 2020 bonus plan in the ordinary course consistent with past practice (including with respect to its executive officers) and may pay bonuses for the 2020 fiscal year (or a portion thereof if the Effective Time occurs during such fiscal year) pursuant to such plan. To the extent any performance period under a Finisar bonus plan is deemed to end on or in connection with the Effective Time, the Compensation Committee of the Finisar Board or other applicable administrator will, prior to the Effective Time, determine the bonus payable pursuant to the terms of the applicable plan. In accordance with the terms of its bonus plans, Finisar may issue Finisar Restricted Stock Units in payment of a portion of the bonuses awarded under the plans, and such Finisar Restricted Stock Units may include provisions allowing for full acceleration of such Finisar Restricted Stock Units on a termination of employment by Finisar or its successor other than for cause.

Under the Merger Agreement and subject to certain limitations, Finisar may grant Finisar Restricted Stock Units to employees, including executive officers, prior to the Effective Time in the ordinary course of business consistent with past practice. Finisar may also increase the annual compensation and benefits of employees, including executive officers, prior to the Effective Time in the ordinary course of business consistent with past practice.

Indemnification and Insurance

Pursuant to the terms of the Merger Agreement, Finisar’s directors and executive officers will be entitled to certain ongoing indemnification by, and continuing directors’ and officers’ liability insurance coverage from, the Surviving Corporation for a period of six years following the Effective Time.

II-VI Board after the Merger

TheII-VI Board will appoint three members of the Finisar Board as of November 8, 2018 to serve on theII-VI Board (the “Finisar Designees”). Each Finisar Designee will be mutually agreed upon byII-VI and Finisar, acting in good faith. In addition, the Corporate Governance and Nominating Committee of theII-VI Board previously will have reasonably approved the appointment of the Finisar Designees to theII-VI Board, which also will have previously recommended the appointment of the Finisar Designees to the fullII-VI Board. The total number of directors on theII-VI Board at the Effective Time will be no more than 11 persons. As of the date hereof, the identity of the Finisar Designees has not been determined byII-VI and Finisar.

Also at the Effective Time, theII-VI Board will have four committees, consisting of an Audit Committee, a Compensation Committee, a Subsidiary Committee and a Corporate Governance and Nominating Committee. Each such committee will include at least one Finisar Designee.

Prior to execution of the Merger Agreement, the parties did not have any discussions or negotiations regarding any post-Merger employment by II-VI of the current executive officers of Finisar. However, II-VI stated its expectation in the May 3 Proposal, the September 14 Proposal and the September 26 Proposal that members of Finisar’s management would be represented appropriately within the combined company of II-VI and Finisar following the consummation of the Merger.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information ofII-VI presents the unaudited pro forma condensed combined balance sheet as of September 30, 2018 and the unaudited pro forma condensed combined statements of operations for the year ended June 30, 2018 and the three months ended September 30, 2018. The unaudited pro forma condensed combined financial information includes the historical results ofII-VI and Finisar after giving pro forma effect to the Merger and other transactions as described in this section and under “Notes to Unaudited Pro Forma Condensed Combined Financial Information.”

The unaudited pro forma condensed combined financial information was prepared in accordance with Article 11 of RegulationS-X. The unaudited pro forma adjustments reflecting the Merger and other transactions described in this section and under “Notes to Unaudited Pro Forma Condensed Combined Financial Information” have been prepared in accordance with the acquisition method of accounting in accordance with FASB ASC Topic 805,Business Combinations, whereII-VI is the accounting acquirer and Finisar is the accounting acquiree.

The unaudited pro forma condensed combined financial information is provided for illustrative purposes only and does not purport to represent what the actual consolidated results of operations or consolidated financial condition would have been had the Merger actually occurred on the dates indicated, nor do they purport to project the future consolidated results of operations or consolidated financial condition for any future period or as of any future date. The assumed accounting for the Merger, including estimated aggregate Merger Consideration, is based on provisional amounts, and the associated purchase accounting is not final. The preliminary allocation of the purchase price to the acquired assets and assumed liabilities was based upon the preliminary estimate of fair values. For the preliminary estimate of fair values of assets acquired and liabilities assumed of Finisar,II-VI used publicly available benchmarking information as well as a variety of other assumptions, including market participant assumptions. The unaudited pro forma adjustments are based upon available information and certain assumptions thatII-VI believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the accompanying unaudited pro forma condensed combined financial information. The purchase price adjustments relating to the Finisar andII-VI combined financial information are preliminary and subject to change, as additional information becomes available and as additional analyses are performed. All pro forma adjustments and their underlying assumptions are described more fully in the notes to the unaudited pro forma condensed combined financial information.

Notes to Unaudited Pro Forma Condensed Combined Financial Information

Note 1. Description of the Merger

II-VI Incorporated(“II-VI”) and Finisar Corporation (“Finisar”) have entered into an Agreement and Plan of Merger, dated as of November 8, 2018 (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, Mutation Merger Sub Inc., a Delaware corporation and wholly owned subsidiary ofII-VI, will be merged with and into Finisar, and Finisar will continue as the surviving corporation in the merger and a wholly owned subsidiary ofII-VI (the “Merger”).

If the Merger is consummated, Finisar stockholders will be entitled to receive, at their election, consideration per share of common stock of Finisar (the “Finisar Common Stock”) consisting of (i) $26.00 in cash, without interest (the “Cash Election Consideration”), (ii) 0.5546 shares ofII-VI common stock (the shares, the“II-VI Common Stock,” and the consideration, the “Stock Election Consideration”), or (iii) a combination of $15.60 in cash, without interest, and 0.2218 shares ofII-VI Common Stock (the “Mixed Election Consideration,” and, together with the Cash Election Consideration and the Stock Election Consideration, the “Merger Consideration”). The Cash Election Consideration and the Stock Election Consideration are subject to proration adjustment pursuant to the terms of the Merger Agreement such that the aggregate Merger Consideration will consist of approximately 60% cash and approximately 40%II-VI Common Stock.

At the effective time of the Merger (the “Effective Time”), each option granted pursuant to Finisar’s 2005 Stock Incentive Plan (as such plan has been further amended and restated) (each, a “Finisar Stock Option”) (or portion thereof) that is outstanding and unexercised as of immediately prior to the Effective Time (whether vested or unvested) will be cancelled and terminated and converted into the right to receive an amount of Mixed Election Consideration that would be payable to a holder of such number of shares of Finisar Common Stock equal to the quotient of (i) the product of (a) the excess, if any, of $26.00 over the exercise price per share of such Finisar Stock Option multiplied by (b) the number of shares of Finisar Common Stock subject to such Finisar Stock Option,divided by (ii) $26.00.

At the Effective Time, each restricted stock unit granted pursuant to Finisar’s 2005 Stock Incentive Plan (as such plan has been further amended and restated) (each, a “Finisar Restricted Stock Unit”) (or portion thereof) that is outstanding and subject to a performance-based vesting condition that relates solely to the value of Finisar Common Stock will, to the extent such Finisar Restricted Stock Unit vests in accordance with its terms in connection with the Merger (the “Participating RSUs”), be cancelled and extinguished and converted into the right to receive the Cash Election Consideration, the Stock Election Consideration or the Mixed Election Consideration at the election of the holder of such Participating RSUs, subject to proration adjustment.

At the Effective Time, each Finisar Restricted Stock Unit (or portion thereof) that is outstanding and unvested and does not vest in accordance with its terms in connection with the Merger and is either (x) subject to time-based vesting requirements only or (y) subject to a performance-based vesting condition other than the value of Finisar Common Stock will be assumed byII-VI (each, an “Assumed RSU”). Each Assumed RSU will be subject to substantially the same terms and conditions as applied to the related Finisar Restricted Stock Unit immediately prior to the Effective Time, including the vesting schedule (and the applicable performance-vesting conditions in the case of a grant contemplated by clause (y) of the preceding sentence) and any provisions for accelerated vesting applicable thereto, except that the number of shares ofII-VI Common Stock subject to each Assumed RSU will be equal to the product of (i) the number of shares of Finisar Common Stock underlying such unvested Finisar Restricted Stock Unit award as of immediately prior to the Effective Timemultiplied by (ii) the sum of (a) 0.2218plus (b) the quotient obtained by dividing (1) $15.60by (2) the volume weighted average price per share ofII-VI Common Stock (rounded to the nearest cent) on the Nasdaq Global Select Market for the ten consecutive trading days ending on (and including) the third trading day immediately prior to the Effective Time (with the resulting number, rounded down to the nearest whole share).

Note 2. Description of Financing Transactions

II-VI Senior Credit Facilities

On November 8, 2018, in connection with its entry into the Merger Agreement,II-VI entered into a commitment letter (together with a related fee letter) with Bank of America, N.A. (“Bank of America”), which was subsequently amended and restated on December 7, 2018 and on December 14, 2018 (together with one or more related fee letters, the “Commitment Letter”). Subject to the terms and conditions set forth in the Commitment Letter, the lender parties thereto (the “Lending Parties”) have severally committed to provide 100% of up to $2.425 billion in aggregate principal amount of senior secured credit facilities ofII-VI (the“II-VI Senior Credit Facilities”) comprised of (i) a “term a” loan facility of up to $1.0 billion, a portion of which will be available after the closing of the Merger on a delayed draw basis, (ii) a “term b” loan facility of up to $975.0 million and (iii) a revolving credit facility of up to $450.0 million.

II-VI currently intends to pay the cash portion of the aggregate Merger Consideration and pay related fees and expenses in connection with the Merger using the proceeds of draws under theII-VI Senior Credit Facilities and cash and short-term investments ofII-VI and Finisar.II-VI also currently intends to use a portion of the proceeds from theII-VI Senior Credit Facilities to repay, in full, its outstanding indebtedness underII-VI’s currently existing credit facility, and to repay, as soon as practicable, its assumed obligations under (i) the Indenture, dated as of December 16, 2013 (the “2033 Notes Indenture”), by and between Finisar and Wells Fargo Bank, National Association, as trustee (the “Trustee”), governing the outstanding 0.50% Convertible Senior Notes due 2033 of Finisar (the “2033 Notes”) and (ii) the Indenture, dated as of December 21, 2016 (the “2036 Notes Indenture” and, together with the 2033 Notes Indenture, the “Indentures”), by and between Finisar and the Trustee, governing the 0.50% Convertible Senior Notes due 2036 of Finisar (the “2036 Notes”).

The documentation governing theII-VI Senior Credit Facilities has not been finalized and, accordingly, the actual terms of theII-VI Senior Credit Facilities may differ from those described herein or in the Commitment Letter. The obligation of the lead arranger parties thereto (the “Lead Arrangers”) to provide the debt financing under the Commitment Letter is subject to a number of conditions. There is a risk that these conditions will not be satisfied and theII-VI Senior Credit Facilities may not be funded when required or at all. No alternative financing arrangements have been made in the event theII-VI Senior Credit Facilities are not available, and any such alternative financing arrangements may not be available on acceptable terms, or at all, if theII-VI Senior Credit Facilities are not consummated. Accordingly, the unaudited pro forma condensed combined financial information has been prepared based on management’s best estimate of the expected debt obligations and interest expense determined based on the terms of the Commitment Letter; however, the actual terms of the financing may differ.

The “term a” loan facility will be subject to equal quarterly repayment of principal in an aggregate amount equal to 5.0% per annum with the final payment of all amounts outstanding, plus unpaid accrued interest, due and payable in full on the earlier to occur of (i) the fifth anniversary of the closing date of the Merger and (ii) the date that is 120 days prior to the stated maturity ofII-VI’s Convertible Senior Notes due 2022 (the “2022 Notes”) if, on such date, any of the 2022 Notes are still outstanding andII-VI has, as of such date and as of each calendar day thereafter until the 2022 Notes are no longer outstanding, consolidated unrestricted cash and cash equivalents and undrawn available commitments under the revolving facility in an amount less than the principal amount of such 2022 Notes then outstanding.

The “term b” loan facility will be subject to equal quarterly repayment of principal in an aggregate amount equal to 1.0% per annum with the final payment of all amounts outstanding, plus unpaid accrued interest, due and payable in full on the earlier to occur of (i) the seventh anniversary of the closing date of the Merger and (ii) the date that is 91 days prior to the stated maturity of the 2022 Notes if, on such date, any of the 2022 Notes are still outstanding andII-VI has, as of such date and as of each calendar day thereafter until the 2022 Notes are no longer outstanding, consolidated unrestricted cash and cash equivalents and undrawn available commitments under the revolving facility in an amount less than the principal amount of such 2022 Notes then outstanding.

175

The revolving credit facility will terminate and all amounts outstanding thereunder, plus unpaid accrued interest, will be due and payable in full on the earlier to occur of (i) the fifth anniversary of the closing date of the Merger and (ii) the date that is 120 days prior to the stated maturity of the 2022 Notes if, on such date, any of the 2022 Notes are still outstanding andII-VI has, as of such date and as of each calendar day thereafter until the 2022 Notes are no longer outstanding, consolidated unrestricted cash and cash equivalents and undrawn available commitments under the revolving facility in an amount less than the principal amount of such 2022 Notes then outstanding.

II-VI has an option to carry theII-VI Senior Credit Facilities as “Base Rate loans,” which will bear interest at the Base Rate (as defined below) in effect from time to time plus an Applicable Margin (as defined below), or “LIBOR loans,” which will bear interest at LIBOR for the respective interest period plus an Applicable Margin. The “Base Rate” means the highest of (a) the Federal Funds Rate plus 0.50%, (b) the Bank of America prime rate and (c) the one month LIBOR adjusted daily plus 1.00%. Subject to the terms and conditions set forth in the Commitment Letter, the “Applicable Margin” means a percentage per annum ranging from (i) in the case ofII-VI Senior Credit Facilities maintained as Base Rate loans, 0.375% to 1.50%, and (ii) in the case ofII-VI Senior Credit Facilities maintained as LIBOR loans, 1.375% to 2.50%.

Treatment of Finisar Convertible Notes

The 2033 Notes Indenture provides that at any time on or after December 22, 2018, Finisar may elect to redeem, in whole or in part, the outstanding 2033 Notes. In the event any 2033 Notes are not repurchased or converted prior to the redemption date,II-VI plans to cause the redemption of any outstanding 2033 Notes as promptly as practicable following the consummation of the Merger. Accordingly,II-VI expects that all such outstanding 2033 Notes will be redeemed on or about the 20th day following the consummation of the Merger.

Pursuant to the terms of the 2036 Notes Indenture, holders of the 2036 Notes do not have an option to require Finisar to repurchase any 2036 Notes held by them until December 15, 2021, and Finisar does not have an option to redeem, in whole or in part, outstanding 2036 Notes until December 22, 2021. The consummation of the Merger will constitute a “Fundamental Change” for purposes of the 2036 Notes Indenture. Upon the occurrence of a Fundamental Change, the holders of the 2036 Notes have the option to cause Finisar (or its successor) to repurchase the 2036 Notes at a price equal to 100% of the principal amount of the notes plus accrued and unpaid interest to, but excluding, the repurchase date. Alternatively, upon the occurrence of a Fundamental Change, the holders of the 2036 Notes may convert such 2036 Notes at an increased conversion rate pursuant to the terms of the 2036 Notes Indenture. In the event any 2036 Notes remain outstanding following such redemption and conversion periods,II-VI plans to cause such 2036 Notes to be redeemed on or around December 22, 2021 (the first date on which Finisar (or its successor) may elect to redeem the 2036 Notes) in accordance with the terms of the 2036 Notes Indenture and any applicable supplemental indenture.II-VI currently expects the 2036 Notes will be surrendered for repurchase by holders in connection with the Fundamental Change provisions of the 2036 Notes Indenture.

Accordingly, the unaudited pro forma condensed combined financial information gives effect to the repayment of the 2033 Notes and 2036 Notes immediately following the completion of the Merger, as if it had occurred on September 30, 2018, in the case of the unaudited pro forma condensed combined balance sheet, and July 1, 2017, in the case of the unaudited pro forma condensed combined statements of operations. Refer to the further discussion in Notes 8(f) and 9(d).

Note 3. Basis of Pro Forma Presentation

The unaudited pro forma condensed combined financial information was prepared pursuant to Article 11 of RegulationS-X.

II-VI and Finisar have different fiscal years.II-VI’s fiscal year ends on June 30. Finisar has a52- or53-week fiscal year ending on the Sunday closest to the last day of April in each calendar year. Finisar’s most

176

recent fiscal year ended on April 29, 2018. Financial information for Finisar for the twelve months ended July 29, 2018 and the three months ended October 28, 2018 have been used in preparation of the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined balance sheet as of September 30, 2018 combines the unaudited historical condensed consolidated balance sheet ofII-VI as of September 30, 2018 with the unaudited historical condensed consolidated balance sheet of Finisar as of October 28, 2018, giving effect to (1) the Merger, and the estimated financing used to finance the Merger, as if it had occurred on September 30, 2018, and (2) the assumptions and adjustments described in the accompanying notes to the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined statement of operations for the year ended June 30, 2018 combines the audited historical consolidated statement of operations ofII-VI for the year then ended with the unaudited historical consolidated statement of operations of Finisar for the twelve months ended July 29, 2018. Finisar’s unaudited historical consolidated statement of operations for the twelve months ended July 29, 2018 was derived by adding the audited consolidated statement of operations of Finisar for the year ended April 29, 2018 to the unaudited condensed consolidated statement of operations of Finisar for the three months ended July 29, 2018 and deducting the unaudited condensed consolidated statement of operations of Finisar for the three months ended July 30, 2017. The unaudited pro forma condensed combined statement of operations for the three months ended September 30, 2018 has been derived fromII-VI’s unaudited historical condensed consolidated statement of operations for the three months then ended and Finisar’s unaudited historical condensed consolidated statement of operations for the three months ended October 28, 2018. The pro forma statements of operations for the year ended June 30, 2018 and the three months ended September 30, 2018 give effect to (1) the consummation of the Merger, and the estimated financing used to finance the Merger, as if it had occurred on July 1, 2017, the beginning ofII-VI’s 2018 fiscal year, and (2) the assumptions and adjustments described in the accompanying notes to the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information has been prepared using the acquisition method of accounting in accordance with the business combination accounting guidance as provided in FASB ASC Topic 805,Business Combinations (“ASC 805”), withII-VI treated as the accounting acquirer and Finisar as the accounting acquiree. The unaudited pro forma condensed combined financial information may differ from the final purchase accounting for a number of reasons, including the fact that the estimates of fair values of assets and liabilities acquired are preliminary and subject to change when the formal valuation and other studies are finalized. The differences that may occur between the preliminary estimates and the final purchase accounting could have a material impact on the accompanying unaudited pro forma condensed combined financial information.

The historical consolidated financial information ofII-VI and Finisar has been adjusted in the unaudited pro forma condensed combined financial information to give effect to pro forma matters that are (i) directly attributable to the Merger, and the estimated financing used to finance the Merger, (ii) factually supportable and (iii) with respect to the unaudited pro forma condensed combined statements of operations, expected to have a continuing impact on the operating results of the combined company. The unaudited pro forma condensed combined financial information does not give effect to the potential impact of any anticipated synergies, operating efficiencies or cost savings that may result from the Merger or of any integration costs. Additionally, the pro forma financial information does not reflect any compensation related adjustments as decisions regarding certain personnel matters are evolving and any recurring impact from compensation adjustments would not be factually supportable. Refer to the further discussion in Note 9(c).

The unaudited pro forma condensed combined financial information is provided for illustrative purposes only and does not purport to represent what the actual consolidated results of operations or the consolidated financial position ofII-VI would have been had the Merger occurred on the dates assumed, nor is it necessarily indicative of the future consolidated results of operations or consolidated financial position of the combined

177

company. See “Where You Can Find More Information” beginning on page 223 of this joint proxy statement/prospectus. The unaudited pro forma condensed combined financial information was based on, and should be read in conjunction with, the following historical consolidated financial statements and accompanying notes, which are incorporated by reference into this joint proxy statement/prospectus:

• the separate audited historical consolidated financial statements ofII-VI as of, and for its fiscal year ended, June 30, 2018, and the related notes included inII-VI’s Current Report on Form8-K filed on December 27, 2018;

• the separate audited historical consolidated financial statements of Finisar as of, and for its fiscal year ended April 29, 2018, and the related notes included in Finisar’s Annual Report on Form10-K for its fiscal year ended April 29, 2018;

• the separate unaudited historical condensed consolidated financial statements ofII-VI as of, and for its fiscal quarter ended, September 30, 2018, and the related notes included inII-VI’s Quarterly Report on Form10-Q for its fiscal quarter ended September 30, 2018;

• the separate unaudited historical condensed consolidated financial statements of Finisar as of, and for its fiscal quarter ended, July 29, 2018, and the related notes included in Finisar’s Quarterly Report on Form10-Q for its fiscal quarter ended July 29, 2018; and

• the separate unaudited historical condensed consolidated financial statements of Finisar as of, and for its fiscal quarter ended, October 28, 2018, and the related notes included in Finisar’s Quarterly Report on Form10-Q for its fiscal quarter ended October 28, 2018.

Note 4. Summary of Significant Accounting Policies

The accounting policies used in the preparation of the unaudited pro forma condensed combined financial information are those set out inII-VI’s audited consolidated financial statements as of and for the year ended June 30, 2018 andII-VI’s unaudited condensed consolidated financial statements as of and for the three months ended September 30, 2018. Management has determined that certain adjustments, including those described in Notes 8 and 9, are necessary to conform Finisar’s financial statements to the accounting policies used byII-VI in the preparation of the unaudited pro forma condensed combined financial information. The adjustment amounts are subject to change as further assessment is performed and finalized for purchase accounting. These reclassifications and adjustments have no effect on previous reported total assets, total liabilities, shareholders’ equity or income from continuing operations ofII-VI or Finisar.

As part of the application of ASC 805,II-VI will conduct a more detailed review of Finisar’s accounting policies in an effort to determine if differences in accounting policies require further reclassification or adjustment of Finisar’s results of operations or reclassification or adjustment of assets or liabilities to conform toII-VI’s accounting policies and classifications. Determining the full impact of aligning Finisar’s accounting policies with those ofII-VI will require a detailed analysis. Based on the procedures conducted to date,II-VI is not aware of any material differences after considering significant accounting policy areas except for those described in Notes 8 and 9.

Note 5. Estimate of Consideration Expected to be Transferred

The following is a preliminary estimate of the aggregate Merger Consideration expected to be transferred to effect the Merger. As discussed in Note 2, the Cash Election Consideration and the Stock Election Consideration are subject to proration adjustment pursuant to the terms of the Merger Agreement such that the aggregate

178

Merger Consideration will consist of approximately 60% cash and approximately 40%II-VI Common Stock, which is the basis for the unaudited pro forma condensed combined financial information.

	(in millions)
Estimated cash consideration to be paid to Finisar stockholders and holders of Net Option Shares and Participating RSUs (each as defined in the Merger Agreement)	$	1,838.1
Estimated value ofII-VI Common Stock to be issued to Finisar stockholders and holders of Net Option Shares and Participating RSUs(1)		977.8
Estimated value ofII-VI replacement equity awards attributable to precombination service(2)		67.6
Preliminary estimated Merger Consideration		2,883.5

(1) The estimate is based on an aggregate of 117,824,518 shares of Finisar Common Stock issued and outstanding as of November 30, 2018, Net Option Shares and Participating RSUs that are expected to vest by the closing date of, or in connection with, the Merger, an exchange ratio of 0.2218 shares ofII-VI Common Stock per share of Finisar Common Stock, and the closing price of $37.42 forII-VI Common Stock on the Nasdaq Global Select Market on November 30, 2018, the most recent practicable date for which such information was available. The estimate also assumes that none of the outstanding Finisar 2033 Notes or 2036 Notes will be converted and receive Merger Consideration, as neither the 2033 Notes nor the 2036 Notes are, as of September 30, 2018, convertible or, other than in connection with the Merger as discussed in “The Merger — Treatment of Finisar Convertible Notes”, expected to be convertible prior to the consummation of the Merger, and the value of the consideration received by a holder of $1,000 principal amount of Finisar Convertible Notes that exercises such holder’s option to require Finisar to repurchase such holder’s Finisar Convertible Notes in connection with a Fundamental Change is expected to exceed the value of the consideration received by a holder of $1,000 principal amount of Finisar Convertible Notes that converts such holder’s Finisar Convertible Notes.

(2) Represents the portion of the fair value of Assumed RSUs attributable to precombination services that will be assumed byII-VI upon completion of the Merger. ASC 805 requires that the fair value of replacement awards attributable to precombination service be included in the consideration transferred.

The final estimated aggregate Merger Consideration could significantly differ from the amounts presented in the unaudited pro forma condensed combined financial information due to movements in the price ofII-VI Common Stock up to the closing date of the Merger. A sensitivity analysis related to the fluctuation in the price ofII-VI Common Stock was performed to assess the impact that a hypothetical change of 10% on theII-VI Common Stock price per share on the Nasdaq Global Select Market from November 30, 2018 would have on the estimated aggregate Merger Consideration and goodwill as of the closing date of the Merger, as set forth in the following table:

Change in price per share of II-VI Common Stock	Price per share of II-VI Common Stock		Estimated Merger Consideration		Estimated goodwill
	(dollars in millions, except stock prices)
Increase of 10%	$	41.16	$	2,981.3	$	811.9
Decrease of 10%	$	33.68	$	2,785.7	$	616.4

Note 6. Estimate of Assets to be Acquired and Liabilities to be Assumed

Under the acquisition method of accounting, the identifiable assets acquired and liabilities assumed of Finisar are recognized and measured as of the acquisition date at fair value and added to those ofII-VI. The determination of fair value used in the pro forma adjustments presented herein are preliminary and based on management’s estimates of the fair value and useful lives of the assets to be acquired and liabilities to be assumed and have been prepared to illustrate the estimated effect of the Merger. The final determination of the

179

purchase price allocation, upon completion of the Merger, will be based on Finisar’s net assets acquired as of that date and will depend on a number of factors that cannot be predicted with certainty at this time. Therefore, the actual allocation will differ from the pro forma adjustments presented. For the preliminary estimate of fair values of assets acquired and liabilities assumed of Finisar,II-VI used publicly available benchmarking information as well as a variety of other assumptions, including market participant assumptions. The allocation is dependent upon certain valuation and other studies that have not yet been completed. Accordingly, the pro forma purchase price allocation is subject to further adjustment as additional information becomes available and as additional analyses and final valuations are completed. The can be no assurances that these additional analyses and final valuations will not result in significant changes to the estimates of fair value set forth below.

The following table is a preliminary estimate of the assets to be acquired and the liabilities to be assumed byII-VI in the Merger, reconciled to the estimate of the value of the aggregate Merger Consideration at September 30, 2018:

Assets Acquired and Liabilities Assumed:	(in millions)
Current assets, including cash received	$	1,852.8
Property, plant and equipment(1)		676.1
Other assets		101.5
Intangible assets(2)		861.9
Goodwill(3)		714.1
Total assets acquired		4,206.4
Liabilities assumed(4)		(1,322.9	)
Net assets acquired	$	2,883.5

(1) Property, plant and equipment fair value adjustment is preliminary and based upon management’s estimates after consideration of publicly available benchmarking information.

(2) Preliminary identifiable intangible assets in the unaudited pro forma financial information consist of the following:

	Preliminary Fair Value (in millions)		Estimated Useful Life
Developed technology	$	640.5		6 Years
Customer relationships		130.5		10 Years
Trademarks and trade names		11.8		5 Years
In-process research and development		79.1		n/a

The amortization related to the identifiable intangible assets is reflected as a pro forma adjustment in the unaudited pro forma condensed combined statements of operations based on the estimated useful lives above and as further described in Note 9(b). The identifiable assets and related amortization are preliminary and are based on management’s estimates after consideration of similar transactions. As discussed above, the amount will ultimately be allocated to identifiable intangible assets, and the related amount of amortization may differ materially from this preliminary allocation. In addition, the periods over which the amortization impacts will ultimately be based upon the periods in which the associated economic benefits are expected to be derived, or where appropriate, based on the use of straight-line method. Therefore, the amount of amortization following the Merger may differ significantly between periods based upon the final value assigned and amortization methodology used for each identifiable intangible asset.

(3) Goodwill represents the excess of the aggregate Merger Consideration over the fair value of the underlying net assets acquired. Goodwill is not amortized, but instead is reviewed for impairment at least annually, or more frequently upon the identification of any indicators of impairment. Goodwill is attributable to planned growth in new markets and synergies expected to be achieved from the combined operations ofII-VI and Finisar. Goodwill recorded in the Merger is not expected to be deductible for tax purposes.

180

(4) The liabilities assumed include deferred tax liabilities which represent the deferred tax impact associated with the differences in book and tax basis, including incremental differences created from the preliminary purchase price allocation, and are based on the applicable blended statutory tax rate. For balance sheet purposes, where U.S. tax rates were used, rates were based on recently enacted U.S. tax law, and for statement of operations purposes, where U.S. tax rates were used, rates were based on the tax laws applicable to the respective periods. The effective tax rate of the combined company could be significantly different (either higher or lower) depending onpost-Merger activities, including cash needs, the geographical mix of income and changes in tax law. Because the tax rates used for the pro forma financial information are estimated, the blended rate will likely vary from the actual effective rate in periods subsequent to completion of the Merger. This determination is preliminary and subject to change based upon the final determination of the fair value of the acquired assets and assumed liabilities.

Note 7. Reclassification Adjustments

The following reclassification adjustments were made to conform the presentation of Finisar’s financial information toII-VI’s presentation:

(a) To reclassify $6.3 million of prepaid income taxes to prepaid and refundable income taxes from prepaid and other current assets.

(h) To reclassify $2.6 million of amortization of purchased intangibles to selling, general and administrative for the year ended June 30, 2018.

To reclassify $0.4 million of amortization of purchased intangibles to selling, general and administrative for the three months ended September 30, 2018.

(i) To reclassify $2.3 million of impairment of long-lived assets to other (expense), income net for the year ended June 30, 2018.

(j) To reclassify $244.0 million of research and development to internal research and development for the year ended June 30, 2018.

(1) Represents the adjustment necessary to state acquired inventories to their preliminary estimated fair value. The valuation approaches used in the preliminary assessment of the fair value of inventories were the replacement cost approach and the comparative sales method approach. After the closing of the Merger, the recording of inventories at fair value will increase cost of goods sold as the inventory is sold, which for purposes of this pro forma financial information is assumed to occur within the first year after the Merger. The increase is not reflected in the unaudited pro forma condensed combined statements of operations as it was determined to not have a continuing impact.

(d) Reflects adjustments to arrive at the estimated fair value, largely based on benchmarking analysis of other similar transactions, of the property, plant and equipment and intangible assets.

	(in millions)
Estimated fair value of acquired property, plant and equipment (see Note 6)	$	676.1

183

As discussed in Note 3,II-VI currently expects the 2036 Notes will be surrendered for repurchase by holders in connection with the Fundamental Change provisions of the 2036 Notes Indenture, and therefore the unaudited pro forma condensed combined balance sheet as of September 30, 2018 gives effect to the repayment of the 2036 Notes immediately following the completion of the Merger. To the extent the 2036 Notes are not surrendered for repurchase in connection with the Fundamental Change provisions of the 2036 Notes Indenture, the impact on the unaudited pro forma condensed combined balance sheet would be increases to cash and cash equivalents, other accrued liabilities and long-term debt of $576.6 million, $1.6 million and $575.0 million, respectively, as of September 30, 2018.

(g) Reflects adjustments to deferred tax liabilities which represent the deferred tax impact associated with the differences in book and tax basis (see Note 6).

(h) Reflects (i) the elimination of Finisar’s historical common stock, additional paid in capital and accumulated other comprehensive income, and (ii) the estimated value of II-VI Common Stock to be issued in the Merger and the estimated value of II-VI replacement equity awards.

	(in millions)
Elimination of Finisar historical common stock	$	(0.1	)
Estimated value ofII-VI Common Stock to be issued to Finisar stockholders and holders of Net Option Shares and Participating RSUs (See Note 5)		977.8
Estimated value ofII-VI replacement equity awards attributable to precombination service (See Note 5)		67.6
Pro forma adjustment to common stock		1,045.3

(i) Reflects the elimination of Finisar’s accumulated deficit after pro forma adjustments and recorded transaction costs.

	(in millions)
Elimination of Finisar accumulated deficit	$	1,227.2
Total transaction costs anticipated to be paid (See Note 8a)		(73.0	)
Pro forma adjustment to retained earnings		1,154.2

Note 9. Pro Forma Adjustments for Condensed Combined Statements of Operations

(a) Reflects the elimination of revenues fromII-VI to Finisar, as follows:

(1) Elimination of $17.5 million in revenues and $11.4 million in costs of goods sold in the pro forma statement of operations for the year ended June 30, 2018.

(2) Elimination of $4.0 million in revenues and $1.4 million costs of goods sold in the pro forma statement of operations for the three months ended September 30, 2018.

184

(b) Represents the adjustments to record (i) the elimination of historical depreciation and recognition of new depreciation expense based on the fair value of property, plant and equipment and (ii) the elimination of historical amortization expense and recognition of new amortization expense related to identifiable intangible assets calculated on a straight-line basis. The depreciation of property, plant and equipment is based on the estimated remaining useful lives of the assets, and is calculated on a straight-line basis. The amortization of intangible assets is based on the periods over which the economic benefits of the intangible assets are expected to be realized.

	12 months ended June 30, 2018 (in millions)
Reversal of Finisar’s historical property, plant and equipment depreciation expense	$	(100.4	)
Depreciation of acquired property, plant and equipment		107.9
Pro forma adjustment to property, plant and equipment depreciation expense		7.5

	12 months ended June 30, 2018 (in millions)
Reversal of Finisar’s historical intangible asset amortization expense	$	(5.0	)
Amortization of identifiable intangible assets		122.2
Pro forma adjustment to intangible amortization expense		117.2

	3 months ended September 30, 2018 (in millions)
Reversal of Finisar’s historical property, plant and equipment depreciation expense	$	(23.8	)
Depreciation of acquired property, plant and equipment		25.7
Pro forma adjustment to property, plant and equipment depreciation expense		1.9

	3 months ended September 30, 2018 (in millions)
Reversal of Finisar’s historical intangible asset amortization expense	$	(0.9	)
Amortization of identifiable intangible assets		30.5
Pro forma adjustment to intangible amortization expense		29.6

A 10% change in the valuation of acquired property, plant and equipment would cause a corresponding increase or decrease in the balance of goodwill and annual depreciation expense of approximately $7.5 million and $0.75 million, respectively, assuming an overall weighted-average use life of 10 years. A 10% change in the valuation of acquired intangible assets would also cause a corresponding increase or decrease in the balance of goodwill and annual amortization expense of approximately $86.2 million and $12.2 million, respectively, assuming an overall weighted-average useful life of 6 years for the amortizable intangible assets.

185

(c) Reflects the adjustments to reversenon-recurring transaction costs, which were recorded inII-VI and Finisar’s selling, general and administrative expenses.

The pro forma financial information does not reflect any compensation related adjustments as decisions regarding certain personnel matters are evolving and any recurring impact from compensation adjustments would not be factually supportable. Finisar’s executive officers, including each of Finisar’s named executive officers, are eligible to participate in the Finisar Executive Retention and Severance Plan (the “Severance Plan”). The Severance Plan provides that if, on or within 18 months after a change in control, an executive’s employment is terminated by Finisar (or its successor) without cause or by the executive for good reason (as the terms “cause” and “good reason” are each defined in the Severance Plan), the executive would be entitled to receive as severance: (a) a payment equal to 24 months of the executive’s base salary; (b) a payment equal to the executive’s target annual bonus amount most recently determined by the Compensation Committee of the Finisar Board; (c) reimbursement of the executive’s premiums for continued health and life insurance coverage for up to 24 months; and (d) full acceleration of the executive’s time-based equity awards granted by Finisar.

(d) Reflects the adjustments to (i) reverse interest expense associated with the anticipated repayment ofII-VI’s currently existing credit facility and Finisar’s 2033 Notes and 2036 Notes (including, in each case, amortization of debt issuance costs and discounts), (ii) recognition of new interest expense associated with the II-VI Senior Credit Facilities, and (iii) recognition of new amortization expense associated with debt issuance costs.

	in millions
	12 months ended June 30, 2018			3 months ended September 30, 2018
Interest expense onII-VI Senior Credit Facilities(1) (2)	$	90.8		$	22.7
Amortization of new debt issuance costs related toII-VI Senior Credit Facilities		9.5			2.4
Elimination of historical interest expense related to repayment ofII-VI’s currently existing credit facility		(8.4	)		(2.1	)
Elimination of historical interest expense related to repayment of the 2036 Notes(3)		(24.3	)		(6.2	)
Elimination of historical interest expense related to repayment of the 2033 Notes		(12.6	)		(3.3	)
Financing adjustment to interest expense		55.0			13.5

(1) The interest expense adjustments included in the unaudited pro forma condensed combined statements of operations reflect additional interest expense using interest rates ranging from 4.35% to 4.85%. This rate comprises theone-month LIBOR rate of 2.35% as of November 30, 2018, plus the Applicable Margins specified in the Commitment Letter.

(2) A sensitivity analysis on interest expense for the year ended June 30, 2018 and the three months ended September 30, 2018 has been performed to assess the effect of a change of 12.5 basis points to the hypothetical interest rate on theII-VI Senior Credit Facilities. The following table shows the change in interest expense of the debt financing transaction described in Note 2:

	in millions
	12 months ended June 30, 2018			3 months ended September 30, 2018
Interest Expense Assuming:
Increase of 0.125%	$	2.5		$	0.7
Decrease of 0.125%	$	(2.5	)	$	(0.7	)

186

(3) As discussed in Note 3,II-VI currently expects the 2036 Notes will be surrendered for repurchase in connection with the Fundamental Change provisions of the 2036 Notes Indenture, and therefore the unaudited pro forma condensed combined statements of operations give effect to the repayment of the 2036 Notes as if it had occurred on July 1, 2017. To the extent the 2036 Notes are not surrendered for repurchase in connection with the Fundamental Change provisions of the 2036 Notes Indenture, the impact on the unaudited pro forma condensed combined statements of operations would be an increase to interest expense (and a corresponding increase to net loss) of $24.3 million and $6.2 million for the year ended June 30, 2018 and the three months ended September 30, 2018, respectively, and an increase to net loss per share of $0.27 and $0.07 for the year ended June 30, 2018 and the three months ended September 30, 2018, respectively.

(e) Reflects the adjustment to eliminate interest income associated with the expected settlement of short-term investments.

(f) Reflects the income tax effects of the pro forma adjustments based on the applicable blended statutory tax rate (see Note 6).

(g) Represents the pro forma weighted average shares outstanding that have been calculated using the historical weighted average shares ofII-VI Common Stock outstanding and the additional shares of II-VI Common Stock to be issued in conjunction with the Merger.

	12 months ended June 30, 2018		3 months ended September 30, 2018
HistoricalII-VI weighted average shares outstanding — basic		62,499		63,420
Shares ofII-VI Common Stock to be issued pursuant to the Merger		26,133		26,133
Pro forma weighted average shares outstanding —basic and diluted		88,632		89,553

FINISAR PROPOSAL NO. 1 — ADOPTION OF THE MERGER AGREEMENT

Subject to the approval of the holders of a majority of the outstanding shares of Finisar Common Stock, the Finisar Board has approved and declared advisable the Merger Agreement and the other transactions contemplated thereby, including the Merger, and determined that the terms of the Merger Agreement, the Merger and the other transactions contemplated thereby are fair to and in the best interests of Finisar and its stockholders in order to enable Finisar to consummate the Merger in accordance with the terms of the Merger Agreement. You should read carefully and in its entirety this joint proxy statement/prospectus, including the annexes attached hereto and the documents incorporated by reference, for more detailed information concerning the Merger Proposal and the transactions contemplated thereby. The text of the Merger Agreement is set forth onAnnex A to this joint proxy statement/prospectus.

The affirmative vote of the holders of a majority of the outstanding shares of Finisar Common Stock is required to approve the Merger Proposal. This means that of the outstanding shares of Finisar Common Stock, a majority of such shares must be voted “FOR” the Merger Agreement for it to be adopted. The Merger cannot be completed unless, among other things, Finisar stockholders approve the Merger Proposal.Abstentions will have the effect of a vote “AGAINST” the Merger Proposal.

THE FINISAR BOARD UNANIMOUSLY RECOMMENDS THAT FINISAR STOCKHOLDERS

VOTE “FOR” THE MERGER PROPOSAL.

FINISAR PROPOSAL NO. 2 — ADJOURNMENT OF THE FINISAR SPECIAL MEETING

Finisar is asking its stockholders to authorize the holder of any proxy solicited by the Finisar Board to vote in favor of one or more adjournments of the Finisar Special Meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the Finisar Special Meeting to approve the Merger Proposal. Finisar does not intend to call a vote on the Finisar Adjournment Proposal to solicit additional proxies if the Merger Proposal is approved at the Finisar Special Meeting.

The affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting is required to approve the Finisar Adjournment Proposal. If your shares of Finisar Common Stock are not voted on the Finisar Adjournment Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Finisar Adjournment Proposal, your shares will have no effect on the Finisar Adjournment Proposal.

THE FINISAR BOARD UNANIMOUSLY RECOMMENDS THAT FINISAR STOCKHOLDERS

VOTE “FOR” THE FINISAR ADJOURNMENT PROPOSAL.

188

FINISAR PROPOSAL NO. 3 —NON-BINDING, ADVISORY VOTE ON MERGER-RELATED COMPENSATION FOR FINISAR’S NAMED EXECUTIVE OFFICERS

This section sets forth the information required by Item 402(t) of the SEC’sRegulation S-K regarding compensation for each of Finisar’s named executive officers that is based on, or otherwise relates to, the Merger. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules, and in this section we use such term to describe the Merger-related compensation payable to Finisar’s named executive officers. The “golden parachute” compensation payable to these individuals is subject to anon-binding, advisory vote of Finisar’s stockholders, as described below in this section.

The table below sets forth, for the purposes of this golden parachute disclosure, the amount of payments and benefits that each of Finisar’s named executive officers would receive, assuming that (1) the Effective Time occurred on December 10, 2018 (which is the assumed date solely for purposes of this golden parachute compensation disclosure), and (2) each of Finisar’s named executive officers experienced an involuntary termination of employment at such time that would trigger severance benefits under the Severance Plan. The amounts below are determined using an assumed value of $22.33 per share of Finisar Common Stock (which, in accordance with SEC rules, is the average of the closing prices for a share of Finisar Common Stock for the first five trading days following the public announcement of the Merger), and are based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions described in the footnotes to the table. These amounts are based upon the named executive officer’s compensation levels in effect on December 10, 2018 and outstanding equity awards on December 10, 2018. As a result of the foregoing assumptions, the actual amounts, if any, to be received by an executive officer may materially differ from the amounts set forth below.

Golden Parachute Compensation

Name	Cash Severance ($)(1)		Equity ($)(2)		Perquisites/ Benefits ($)(3)		Tax Reimbursement ($)(4)		Total
Michael E. Hurlston		2,205,000		6,502,875		54,182		—		8,762,057
Joseph A. Young		1,278,750		3,279,183		58,765		—		4,616,698
Todd Swanson		1,278,750		3,279,183		38,660		—		4,596,593
Kurt Adzema		1,237,500		2,714,926		54,849		—		4,007,275
Julie S. Eng		1,118,000		2,368,587		1,545		—		3,488,132

(1) The amounts reported in this column represent the potential cash severance payment the named executive officer would be entitled to receive from Finisar under the Severance Plan upon a “double trigger” qualifying termination, where the executive’s employment is terminated without cause or by the executive for good reason (as such terms are defined in the Severance Plan) on or within 18 months following a change in control of Finisar. For additional information see the section entitled “Interests of Finisar’s Directors and Executive Officers in the Merger” beginning on page 166.

The following table quantifies each separate form of cash compensation included in the aggregate total reported in the column:

Name	Base Salary Component of Severance ($)		Annual Bonus Component of Severance ($)
Michael E. Hurlston		1,400,000		805,000
Joseph A. Young		930,000		348,750
Todd Swanson		930,000		348,750
Kurt Adzema		900,000		337,500
Julie S. Eng		860,000		258,000

189

Each of Finisar’s named executive officers is also eligible to receive a bonus for the 2019 fiscal year under Finisar’s executive bonus program. Any bonus awarded to a named executive officer for fiscal 2019 would be paid 50% in cash and 50% in the form of a Finisar Restricted Stock Unit award, with the number of Finisar Restricted Stock Units subject to the award determined by dividing the dollar amount of the stock portion of the bonus by Finisar’s stock price on a date following the time Finisar’s Compensation Committee determines the bonus amount. These Finisar Restricted Stock Unit awards will have aone-year vesting period. As the amount of the named executive officers’ bonuses for fiscal 2019 has not yet been determined, this table does not include any amount for bonuses that may be awarded to the named executive officers for fiscal 2019 performance. The target bonus amount for fiscal 2019 for each named executive officer is as follows: Mr. Hurlston — $770,000; Mr. Young — $348,750; Mr. Swanson — $348,750; Mr. Adzema — $337,500; Ms. Eng — $258,000.

(2) Pursuant to the terms of the Merger Agreement and as described above in the section entitled “The Merger Agreement — Treatment of Finisar Employee Stock Plans,” (i) each of the named executive officers’ Finisar Stock Options and Performance-Based RSUs that are outstanding immediately prior to the Effective Time will vest and be settled in accordance with the Merger Agreement, and (ii) each of the named executive officers’ Time-Based RSU awards will be assumed byII-VI and continue to be subject to substantially the same terms and conditions (including vesting requirements) as in effect immediately prior to the Effective Time, except that the number of shares ofII-VI Common Stock subject to such Assumed RSU will be adjusted as described in the section entitled “The Merger Agreement — Treatment of Finisar Employee Stock Plans — Restricted Stock Units,” provided that such Time-Based RSU awards are subject to accelerated vesting under the Severance Plan upon a “double-trigger” qualifying termination of the named executive officer’s employment as described in note (1) above.

For purposes of this note and the table above, the value of the unvested Finisar equity awards is calculated as follows: (i) in the case of a Finisar Stock Option, the applicable number of Net Option Shares for that option (determined as described above in the section entitled “The Merger Agreement — Treatment of Finisar Equity Awards”) multiplied by the assumed value of a share of Finisar Common Stock ($22.33); and (ii) in the case of Finisar Restricted Stock Unit awards, the assumed value of a share of Finisar Common Stock ($22.33) multiplied by the number of shares of Finisar Common Stock subject to the award. In addition, we have assumed for purposes of this table that a “double-trigger” qualifying termination of each named executive officer’s employment as described in note (1) above would occur in connection with the closing. As reflected in the table below, the value of Mr. Hurlston’s outstanding Finisar Stock Option for purposes of this disclosure based on the Net Option Shares for the Finisar Stock Option is $2,376,939. Alternatively, if Mr. Hurlston’s Finisar Stock Option were valued based on the difference between the assumed value per share of Finisar Common Stock ($22.33) and the exercise price per share of the option ($22.26), the value of his option would be $51,800.

The vesting of each of the Performance-Based RSUs held by the named executive officers is subject to Finisar’s achievement ofpre-established stock price targets as described above in the section entitled “Interests of Finisar’s Directors and Executive Officers in the Merger.” For purposes of this table, the number of shares of Finisar Common Stock subject to each Performance-Based RSU is assumed to be the number of Finisar Restricted Stock Units that would vest based on a stock price of between $22.50 and $27.00 per share (i.e.,one-third of the maximum number of Finisar Restricted Stock Units subject to the award) as provided under the terms of these awards described above.

The following table presents the allocation of Finisar Stock Options, Performance-Based RSUs and Time-Based RSUs for each named executive officer that would accelerate in connection with the Merger or a qualifying termination of the executive’s employment and reported in the “Equity” column of the table above:

Name	Aggregate Value of Accelerated Finisar Stock Options ($)		Aggregate Value of Accelerated Performance-Based RSUs ($)		Aggregate Value of Accelerated Time-Based RSUs ($)
Michael E. Hurlston		2,376,939		1,116,500		3,009,436
Joseph A. Young		—		511,714		2,767,469
Todd Swanson		—		511,714		2,767,469
Kurt Adzema		—		470,783		2,244,143
Julie S. Eng		—		388,899		1,979,688

(3) The amounts reported in this column represent the estimated cost to reimburse the named executive officer’s health and life insurance premiums under the Severance Plan assuming a “double-trigger” qualifying termination of the named executive officer’s employment as described in note (1) above.

(4) None of the named executive officers is entitled to a“gross-up” payment for any excise taxes that may be due by reason of Sections 280G and 4999 of the Code.

Merger-Related Compensation Proposal

Pursuant to Section 14A of the Exchange Act and Rule14a-21(c) thereunder, Finisar is seeking anon-binding, advisory stockholder approval of the compensation of Finisar’s named executive officers that is based on or otherwise relates to the Merger as disclosed above in this section. The proposal gives Finisar’s stockholders the opportunity to express their views on the Merger-related compensation of Finisar’s named executive officers.

Accordingly, Finisar is asking its stockholders to vote in favor of the adoption of the following resolution, on anon-binding, advisory basis:

“RESOLVED, that the compensation that will or may be paid or become payable to Finisar’s named executive officers in connection with the merger and the related agreements or understandings pursuant to which such compensation will or may be paid or become payable, in each case as disclosed pursuant to Item 402(t) of RegulationS-K in“Non-Binding, Advisory Vote on Merger-Related Compensation for Finisar’s Named Executive Officers” is hereby APPROVED.”

The vote on the Compensation Proposal is separate and apart from the vote on the Merger Proposal. Accordingly, you may vote to approve the Merger Proposal and vote not to approve the Compensation Proposal and vice versa. Because the vote on the Compensation Proposal is advisory only, it will not be binding on Finisar,II-VI or the Surviving Corporation. If the Merger is completed, the Merger-related compensation may be paid to Finisar’s named executive officers (to the extent payable in accordance with the terms of the compensation agreements and arrangements) even if Finisar stockholders fail to approve the Compensation Proposal.

The approval, bynon-binding, advisory vote, of the Merger-related executive compensation requires the affirmative vote of a majority of the votes cast on such proposal at the Finisar Special Meeting. If your shares of Finisar Common Stock are not voted on the Compensation Proposal, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary, or if you abstain on the Compensation Proposal, your shares will have no effect on the Compensation Proposal.

THE FINISAR BOARD UNANIMOUSLY RECOMMENDS THAT FINISAR STOCKHOLDERS VOTE “FOR” THE COMPENSATION PROPOSAL.

II-VI PROPOSAL NO. 1 — APPROVAL OF ISSUANCE OFII-VI COMMON STOCK IN CONNECTION WITH THE MERGER

As discussed throughout this joint proxy statement/prospectus,II-VI is asking its shareholders to approve the issuance ofII-VI Common Stock in connection with the Merger. You should read carefully and in its entirety this joint proxy statement/prospectus, including the annexes attached hereto and the documents incorporated by reference, for more detailed information concerning the Share Issuance Proposal.

The affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast, assuming a quorum is present, is required to approve the Share Issuance Proposal. Abstentions will have the same effect as a vote “AGAINST” the Share Issuance Proposal, but shares deemed not in attendance at the meeting, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary will have no effect on the Share Issuance Proposal. This vote will satisfy the vote requirements of Listing Rule 5635(d) of the Nasdaq Stock Market with respect to the Share Issuance Proposal. The Merger cannot be completed unlessII-VI shareholders approve the Share Issuance Proposal.

THEII-VI BOARD UNANIMOUSLY RECOMMENDS THATII-VI SHAREHOLDERS VOTE

“FOR” THE SHARE ISSUANCE PROPOSAL.

II-VI PROPOSAL NO. 2 — ADJOURNMENT OF THEII-VI SPECIAL MEETING

II-VI is asking its shareholders to authorize the holder of any proxy solicited by theII-VI Board to vote in favor of one or more adjournments of theII-VI Special Meeting, if deemed necessary or appropriate by II-VI, in its discretion, to solicit additional proxies if there are insufficient votes at the time of theII-VI Special Meeting to approve the Share Issuance Proposal or if a quorum is not present at its special meeting.II-VI does not intend to call a vote on theII-VI Adjournment Proposal to solicit additional proxies if the Share Issuance Proposal is approved at theII-VI Special Meeting. Any determination of whether it is necessary or appropriate to adjourn the II-VI Special Meeting to solicit additional proxies will be made on or behalf of II-VI by the presiding officer of the II-VI Special Meeting (as determined in accordance with the II-VI By-Laws) and will be consistent with the terms of the Merger Agreement.

The affirmative vote of at least a majority of the votes that allII-VI shareholders present at theII-VI Special Meeting, in person or by proxy, are entitled to cast, whether or not a quorum is present, is required to approve theII-VI Adjournment Proposal. Abstentions will have the same effect as a vote “AGAINST” theII-VI Adjournment Proposal, but shares deemed not in attendance at the meeting, whether due to a record holder’s failure to vote or a “street name” holder’s failure to provide any voting instructions to such holder’s nominee or intermediary will have no effect on theII-VI Adjournment Proposal.

THEII-VI BOARD UNANIMOUSLY RECOMMENDS THATII-VI SHAREHOLDERS

VOTE “FOR” THEII-VI ADJOURNMENT PROPOSAL.

DESCRIPTION OFII-VI’S CAPITAL STOCK

II-VI’s authorized capital stock consists of 300,000,000 shares of common stock, no par value, and 5,000,000 shares of preferred stock, no par value. The following description ofII-VI’s capital stock does not purport to be complete and is subject to, and qualified in its entirety by, the relevant provisions of Pennsylvania law, theII-VI Charter and theII-VIBy-Laws.

Common Stock

As of January 17, 2019, there were 63,327,957 shares ofII-VI Common Stock outstanding.

The holders ofII-VI Common Stock are entitled to one vote per share on all matters to be voted upon by the shareholders. The holders ofII-VI Common Stock are not entitled to cumulative voting of their shares in elections of directors. Subject to preferences that may be applicable to any outstanding preferred stock, the holders ofII-VI Common Stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by theII-VI Board out of funds legally available therefor. In the event of a liquidation, dissolution or winding up ofII-VI, the holders ofII-VI Common Stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any then outstanding shares of its preferred stock. Holders ofII-VI Common Stock have no preemptive or conversion rights or other subscription rights.II-VI Common Stock is not subject to any redemption or sinking fund provisions. The rights, preferences, and privileges of holders ofII-VI Common Stock are subject to, and may be adversely affected by, the rights of holders of shares of its preferred stock, as discussed below.

Preferred Stock

No shares of preferred stock are outstanding. Pursuant to theII-VI Charter, theII-VI Board has the authority, without further action by the shareholders, to issue from time to time up to 5,000,000 shares of preferred stock in one or more series. TheII-VI Board may designate the rights, preferences, privileges, and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, redemption rights, liquidation preference, sinking fund terms, and the number of shares constituting any series or the designation of any series.

The issuance of preferred stock could have the effect of restricting dividends onII-VI Common Stock, diluting the voting power ofII-VI Common Stock, impairing the liquidation rights ofII-VI Common Stock, or delaying, deterring, or preventing a change in control. Such issuance could have the effect of decreasing the market price ofII-VI Common Stock.II-VI currently has no plans to issue any shares of preferred stock.

Anti-Takeover Provisions

Certain provisions of Pennsylvania law and theII-VI Charter and theII-VIBy-Laws could make the acquisition ofII-VI by means of a tender offer, or the acquisition of control ofII-VI by means of a proxy contest or otherwise more difficult. These provisions, summarized below, are intended to discourage certain types of coercive takeover practices and inadequate takeover bids, and are designed to encourage persons seeking to acquire control ofII-VI to negotiate with theII-VI Board.II-VI believes that the benefits of increased protection against an unfriendly or unsolicited proposal to acquire or restructureII-VI outweigh the disadvantages of discouraging such proposals. Among other things, negotiation of such proposals could result in an improvement of their terms.

193

Pennsylvania State Law Provisions

II-VI is subject to various anti-takeover provisions of the Pennsylvania Business Corporation Law (the “BCL”). Many of these provisions are triggered if any person or group acquires, or discloses intent to acquire, 20% or more of a Pennsylvania corporation’s voting power, subject to certain exceptions. These provisions:

• provide the other shareholders of the corporation with certain rights against the acquiring group or person;

• prohibit the corporation from engaging in a broad range of business combinations with the acquiring group or person;

• restrict the voting and other rights of the acquiring group or person; and

• provide that certain profits realized by the acquiring group or person from the sale of a corporation’s equity securities belong to and are recoverable by such corporation.

Regardless of the amount of a person’s holdings, if a shareholder or shareholder group (including affiliated persons) would be a party to certain proposed transactions withII-VI or would be treated differently from other shareholders ofII-VI in certain proposed transactions, the BCL requires approval by a majority of votes entitled to be cast by all shareholders other than the interested shareholder or affiliate group, unless the transaction is approved by independent directors or other criteria are satisfied. Furthermore, under the BCL, a “short-form” merger ofII-VI cannot be implemented without the consent of theII-VI Board.

In addition, as permitted by Pennsylvania law, an amendment to theII-VI Charter or other corporate action that is approved by shareholders may provide mandatory special treatment for specified groups ofnon-consenting shareholders of the same class. For example, an amendment to theII-VI Charter or other corporate action may provide that shares ofII-VI Common Stock held by designated shareholders of record must be cashed out at a price determined byII-VI, subject to applicable dissenters’ rights. In these cases, Pennsylvania law requires either a special class vote or dissenters’ rights for holders of the group designated for special treatment.

Furthermore, the BCL provides that directors may, in discharging their duties, consider, to the extent they deem appropriate, the effects of any action upon shareholders, employees, suppliers, customers and the communities in which its offices are located. Directors are not required to consider the interests of shareholders to a greater degree than other constituencies’ interests. The BCL expressly provides that directors do not violate their fiduciary duties solely by relying on “poison pills” or the anti-takeover provisions of the BCL.II-VI does not currently have a “poison pill.”

Other Provisions in theII-VI Charter and theII-VIBy-Laws

TheII-VI Charter and theII-VIBy-Laws contain provisions that could makeII-VI a less attractive target for a hostile takeover and could make more difficult or discourage a merger proposal, a tender offer or a proxy contest.

Such provisions include:

• a requirement that shareholder-nominated director nominees be nominated in advance of the meeting at which directors are elected and that specific information be provided in connection with such nomination;

• the ability of theII-VI Board to issue additional shares ofII-VI Common Stock or preferred stock without shareholder approval; and

• certain provisions requiring supermajority approval (at leasttwo-thirds of the votes cast by all shareholders entitled to vote thereon, voting together as a single class).

COMPARISON OF SHAREHOLDERS’ RIGHTS

The rights ofII-VI’s shareholders currently are governed by Pennsylvania law, theII-VI Charter and theII-VIBy-Laws. The rights of Finisar stockholders currently are governed by Delaware law, the Finisar Charter and the Finisar Bylaws. Following completion of the Merger, the rights of Finisar stockholders who become shareholders ofII-VI in the Merger will be governed by Pennsylvania law, theII-VI Charter and theII-VIBy-Laws.

The following discussion summarizes the material differences between the current rights ofII-VI shareholders and the current rights of Finisar stockholders. These differences arise in part from differences between Pennsylvania law and Delaware law. Additional differences arise from the governing instruments of the two companies.

Although it is impracticable to compare all of the aspects in which Pennsylvania law and Delaware law andII-VI’s and Finisar’s respective governing instruments differ with respect to shareholder rights, the following discussion summarizes certain material differences between them. This summary is not intended to be complete, and it is qualified in its entirety by reference to Pennsylvania law, Delaware law, theII-VI Charter, theII-VIBy-Laws, the Finisar Charter and the Finisar Bylaws. In addition, the identification of some of the differences in the rights of these shareholders as material is not intended to indicate that other differences that are equally important do not exist.II-VI and Finisar urge you to carefully read this entire joint proxy statement/prospectus, the relevant provisions of Pennsylvania law and Delaware law and the other documents to whichII-VI and Finisar refer in this joint proxy statement/prospectus for a more complete understanding of the differences between the rights of aII-VI shareholder and the rights of a Finisar stockholder.II-VI and Finisar have filed with the SEC their respective governing documents referenced in this comparison of shareholder rights and will send copies of these documents to you, without charge, upon your written or telephonic request. See “Where You Can Find More Information” beginning on page 223 of this joint proxy statement/prospectus.

Material Differences in Shareholder Rights

	II-VI Shareholder Rights	Finisar Stockholder Rights
Authorized Capital Stock	As of January 18, 2019, the authorized capital stock ofII-VI consists of (i) 300,000,000 shares of common stock, no par value, and (ii) 5,000,000 shares of preferred stock, no par value.	As of January 18, 2019, the authorized capital stock of Finisar consists of (i) 750,000,000 shares of common stock, $0.001 par value, and (ii) 5,000,000 shares of preferred stock, $0.001 par value.
	TheII-VI Board may in its discretion, at any time or from time to time, issue or cause to be issued all or any part of the authorized and unissued shares of preferred stock. Pursuant to theII-VI Charter, 300,000 shares of preferred stock have been designated as “Series One Preferred Stock” with such rights and preferences as further described in theII-VI Charter. TheII-VI Board is authorized, at any time or from time to time, to divide any or all of such other shares of preferred stock into one or more other series, to fix and	The Finisar Board is authorized, subject to any limitations prescribed by law, to provide for the issuance of the shares of preferred stock in series, and to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences, and rights of the shares of each such series and any qualifications, limitations or restrictions thereon.

196

	determine the number of shares and the designation of such series, and to fix and determine the designations, voting rights, preferences, qualifications, limitations, restrictions and special or relative rights of the preferred stock or of such series, to the fullest extent permitted by the laws of the Commonwealth of Pennsylvania.
	As of January 17, 2019, there were outstanding (i) 63,327,957 shares ofII-VI Common Stock and (ii) no shares ofII-VI preferred stock (including shares of Series One Preferred Stock).	As of January 17, 2019, there were outstanding (i) 117,898,219 shares of Finisar Common Stock and (ii) no shares of Finisar preferred stock.
Number of Directors	TheII-VI Board currently has eight members. Under theII-VBy-Laws, the number of directors on theII-VI Board shall be at least five and not more than 11 directors, the exact number to be set from time to time by resolution of theII-VI Board.	The Finisar Board currently has eight members. The Finisar Charter provides that the authorized number of members of the Finisar Board shall be fixed from time to time by the Finisar Board.
	Pennsylvania law permits classified boards of directors. TheII-VI Board is divided into three classes, each consisting of as nearly an equal number of directors as practicable. As of the date of this joint proxy statement/prospectus, theII-VI Board consists of three directors in Classes One and Two and two directors in Class Three.	Delaware law permits classified boards of directors. The Finisar Board is divided into three classes, each consisting of as nearly an equal number of directors as practicable, with each director serving until the third annual meeting of stockholders following his or her election subject to such director’s earlier resignation or removal. As of the date of this joint proxy statement/prospectus, the Finisar Board consists of two directors in Class I and three directors in each of Classes II and III.
	At the Effective Time, theII-VI Board will increase the number of directors on theII-VI Board to 11 and appoint three members of the Finisar Board to serve on theII-VI Board.
Election of Directors	TheII-VI Charter and theII-VIBy-Laws provide for a majority vote standard for uncontested elections of directors. Under theII-VI Charter and theII-VIBy-Laws, a majority of votes cast means that the number of votes “for” a director’s election must	The Finisar Bylaws provide for a plurality of votes standard for elections of directors. Under this voting standard, once a quorum has been established, nominees receiving the highest number of affirmative votes of the shares entitled to be

197

exceed the number of votes cast “against” that director’s election. “Abstentions” and “brokernon-votes” will not count as votes cast with respect to that director’s election. Under theII-VIBy-Laws, if an incumbent director nominee does not receive a majority of the votes cast in an uncontested election, the incumbent director will continue to serve on theII-VI Board. However, each incumbent director nominee has submitted to theII-VI Board an irrevocable conditional resignation, which is effective if the nominee receives a greater number of votes “against” than votes “for” that person’s election in an uncontested election. Under theII-VIBy-Laws, if this occurs, theII-VI corporate governance and nominating committee will recommend to theII-VI Board whether to accept or reject the resignation, or if other action should be taken. TheII-VI Board will act on the resignation, taking into account theII-VI corporate governance and nominating committee’s recommendation, and publicly disclose its decision and the underlying rationale within 90 days after the date the election results are certified. TheII-VI nominating and corporate governance committee in making its recommendation, and theII-VI Board in making its decision, may consider any facts and circumstances it deems appropriate, including, without limitation, such factors outlined in theII-VIBy-Laws.   TheII-VI Charter and theII-VIBy-Laws provide for a plurality of votes standard for contested elections of directors. Under a plurality of votes standard, once a quorum has been established, nominees receiving the highest number of affirmative votes of the shares entitled to be voted up to the number of directors to be elected will be elected as directors. voted up to the number of directors to be elected will, subject to Finisar’s Plurality Plus Voting Policy (the “Voting Policy”), be elected as directors. Votes withheld have no legal effect. Pursuant to the Voting Policy, in an uncontested election of directors, if a nominee for director receives a greater number of “withhold” votes than “for” votes, the director must tender his or her resignation to the Finisar Board promptly following the certification of the election results. The Finisar nominating and corporate governance committee will consider any resignation tendered under the Voting Policy and recommend to the Finisar Board whether to accept or reject such resignation. The Finisar Board will then act on such resignation, taking into account the recommendation of the Finisar nominating and corporate governance committee, within 90 days following the certification of the election results. The Finisar nominating and corporate governance committee in making its recommendation, and the Finisar Board in making its decision, may consider any information it deems appropriate, including, without limitation, such factors outlined in the Voting Policy. The Finisar Board will disclose, as required by law, its decision to accept or reject such resignation and, if rejected, the reasons for doing so.

198

Removal of Directors	Pennsylvania law provides that, if the corporation has a classified board of directors effected by a charter or bylaw provision adopted by shareholders (such as theII-VI provisions), the entire board of directors, any class of the board of directors or any individual director may be removed from office by a vote of the shareholders only for cause, unless the articles of incorporation unambiguously allow removal without cause. The classification of theII-VI Board has been effected in theII-VI Charter, and, under theII-VI Charter, any director, any class of directors, or the entireII-VI Board may be removed from office by a vote of the shareholders at any time, with or without assigning any cause, but only if shareholders entitled to cast at leasttwo-thirds (2/3) of the votes which all shareholders would be entitled to cast at an annual election of directors or of such class shall vote in favor of such removal.	Under Delaware law, directors may be removed with or without cause by the affirmative vote of holders of a majority of all the shares of stock outstanding and entitled to vote for the election of directors unless the corporation has a staggered board or cumulative voting. If the corporation has a staggered board, such as Finisar, directors may be removed only for cause unless the certificate of incorporation otherwise provides. The Finisar Charter provides that any directors, or the entire Finisar Board, may be removed from office at any time, with or without cause, but only by the affirmative vote of the holders of at least a majority of the voting power of all of the then outstanding shares of capital stock of Finisar entitled to vote generally in the election of directors, voting together as a single class.
Voting	Under Pennsylvania law and theII-VI Charter, each holder ofII-VI Common Stock is entitled to one vote per share ofII-VI Common Stock.	Under Delaware law, unless the certificate of incorporation provides otherwise, each holder of capital stock is entitled to one vote per share. The holders of Finisar Common Stock are entitled to one vote per share of Finisar Common Stock.
Cumulative Voting	Pennsylvania law allows for cumulative voting, but theII-VI Charter expressly precludes cumulative voting in the election of directors.	Under Delaware law, Finisar stockholders are not entitled to cumulative voting unless it is expressly provided for in the certificate of incorporation. The Finisar Charter does not provide for cumulative voting.
Vacancies on the Board of Directors	Under Pennsylvania law and theII-VIBy-Laws, vacancies on theII-VI Board shall be filled by a majority of the remaining members of theII-VI Board though less than a quorum or by a sole remaining director.	Under Delaware law, the Finisar Charter and the Finisar Bylaws, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the Finisar Board resulting from death, resignation, retirement, disqualification or other cause (other than removal from office by a vote of

199

		the Finisar stockholders) may be filled only by a majority vote of the directors then in office, though less than a quorum. Under the Finisar Charter, a vacancy resulting from the removal of a director by vote of the Finisar stockholders may be filled by a majority of the directors then in office, though less than a quorum, or at a special meeting of the Finisar stockholders held for that purpose.
Special Meeting of the Board of Directors	Under theII-VIBy-Laws, special meetings of theII-VI Board may be called at any time by theII-VI Board itself by vote at a meeting, by any director or by the chairman.	Under the Finisar Bylaws, special meetings of the Finisar Board may be called byone-third of the directors then in office (rounded up to the nearest whole number) or by the chief executive officer.
Stockholder Action by Written Consent	Under Pennsylvania law, unless otherwise restricted in a corporation’s bylaws, any action required or permitted to be taken at a meeting of shareholders may be taken without a meeting if a written consent is signed by all of the shareholders who would be entitled to vote at a shareholder meeting for that purpose. Under Pennsylvania law applicable to a registered corporation, shareholders may not act by less than unanimous written consent unless otherwise provided in the articles of incorporation. TheII-VI Charter does not provide for shareholder action by less-than-unanimous consent.	Under the Finisar Charter, stockholder action may only be taken at an annual meeting or special meeting and not by written consent.
Amendment to Articles of Incorporation	Under Pennsylvania law applicable to a registered corporation, an amendment to a corporation’s articles can be proposed by a resolution of the corporation’s board of directors or by shareholders if provided in the corporation’s articles of incorporation or bylaws. TheII-VI Charter andBy-Laws do not provide for shareholder proposal of amendments. Unless a greater vote is required by a corporation’s articles, any such proposal may then be approved by an affirmative vote of a majority of the votes cast by all shareholders entitled to vote thereon,	Under Delaware law, an amendment to a corporation’s certificate of incorporation generally requires (i) the approval of the board of directors, (ii) the approval of a majority of the voting power of the outstanding stock entitled to vote upon the proposed amendment and (iii) the approval of the holders of a majority of the outstanding stock of each class entitled to vote thereon as a class, if any. Under the Finisar Charter, the affirmative vote of the holders of at leasttwo-thirds of the voting power of all of the then outstanding shares of the capital

200

	except for amendments on certain specified matters that do not require shareholder approval. TheII-VI Charter requires that an amendment changing, repeal of, or adoption of a provision inconsistent with provisions in theII-VI Charter relating to the amendment of theII-VI Charter or the removal of directors, or provisions of theII-VIBy-Laws relating to the number of directors, the classification of directors, and/or the filling of vacancies on theII-VI Board, must be approved by the affirmative vote of shareholders entitled to cast at leasttwo-thirds of votes which all shareholders would be entitled to cast at an annual election of directors unless such amendment, repeal, or adoption is unanimously approved by all of the directors.	stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, is required to amend provisions in the Finisar Charter relating to the amendment of the Finisar Charter, the calling of a special meeting of stockholders, stockholder action by written consent, the number of directors, the classification of directors, the filling of vacancies, the adoption, amendment, or repeal of the Finisar Bylaws, or the liability of directors for breaches of fiduciary duties.
Amendment ofBy-Laws	Under theII-VIBy-Laws, theII-VIBy-Laws may be altered, amended, and repealed by (i) the vote of shareholders entitled to cast at least a majority of the votes which all shareholders are entitled to cast or (ii) with respect to any subject that is by statute committed expressly to the shareholders, the vote of a majority of theII-VI Board, at any regular or special meeting. Pennsylvania law does not allow shareholders of a registered corporation to adopt a bylaw that varies the authority, powers, and functions of the board of directors or that establishes a committee of the board. In addition, theII-VI Charter requires that an amendment changing, the repeal of, or the adoption of a provision inconsistent with provisions of theII-VIBy-Laws relating to the number of directors, the classification of directors, and/or the filling of vacancies on theII-VI Board must be approved by the affirmative vote of shareholders entitled to cast at leasttwo-thirds of votes which all shareholders would be entitled to cast	Under the Finisar Charter and the Finisar Bylaws, (i) the Finisar Board may amend the Finisar Bylaws upon the approval of a majority of the total number of authorized directors (whether or not there exist any vacancies in previously authorized directorships at the time any resolution providing for adoption, amendment or repeal is presented to the Board), and (ii) the Finisar stockholders may amend the Bylaws by the affirmative vote of the holders of at leasttwo-thirds of the voting power of all of the then outstanding shares of the capital stock of Finisar entitled to vote generally in the election of directors.

	at an annual election of directors, unless such amendment, repeal, or adoption is unanimously approved by all of the directors.
Special Shareholder Meetings	Under Pennsylvania law, shareholders of a Pennsylvania registered business corporation do not have a statutory right to call special meetings of shareholders (except to approve certain “business combinations” pursuant to one of the “Anti-Takeover” provisions summarized below) unless the corporation’s articles of incorporation provide otherwise. Moreover, no such article provision may authorize a special meeting to be called by fewer than 25% of votes that might be cast at the meeting.II-VI has not adopted any provision in theII-VI Charter with respect to the call of special shareholder meetings. Under theII-VIBy-Laws, special meetings of the shareholders may be called at any time, by theII-VI Board or its chairman, for any purpose or purposes set forth in the call by delivering a written request to the corporate secretary. Special meetings are held not more than 60 days after receipt by the corporate secretary of the request.	Under the Finisar Charter and the Finisar Bylaws, special meetings of stockholders may be called only (i) by the Finisar Board pursuant to a resolution adopted by a majority of the total number of authorized directors or (ii) by the holders of not less than ten percent of all of the shares entitled to vote at the meeting, voting together as a single class and are held at such place, on such date, and at such time as they shall fix.

In the event Finisar calls a special meeting of stockholders for the purpose of electing directors, any stockholder entitled to vote in such election may nominate a person or persons for election to such position(s) as specified in the notice of meeting, if the stockholder’s notice required by the notice provisions described in greater detail in the section titled “Comparison of Shareholders’ Rights — Shareholder Nominations of Persons for Election as Directors” beginning on page 203 of this joint proxy statement/ prospectus with respect to any nomination is delivered to the corporate secretary at the principal

Notice of Shareholder Meetings	Under Pennsylvania law and theII-VIBy-Laws, written notice of each shareholders’ meeting must be given at least five days prior to the meeting. Pennsylvania law and theII-VIBy-Laws require notice of a meeting to vote on certain fundamental changes to be given at least ten days before the date of such meeting.	Under Delaware law and the Finisar Bylaws, written notice of each stockholders’ meeting must be given at least ten days but no more than 60 days before the date of the meeting. Delaware law requires notice of a meeting to vote on a merger agreement, a sale, lease or exchange of all or substantially all assets, a conversion to another form of entity or a transfer, domestication or conveyance to a foreign jurisdiction to be given at least 20 days before the date of such meeting.
Shareholder Nominations of Persons for Election as Directors	TheII-VIBy-Laws generally permit shareholders to nominate persons for election as directors at annual meetings of shareholders if the shareholder intending to make such nomination gives timely notice thereof in proper form. To be timely, a shareholder’s written notice must be delivered to the corporate secretary no later than the close of business on the 120th day and no earlier than the close of business on the 150th day before the anniversary date of the mailing date ofII-VI’s proxy statement in connection with the previous year’s annual meeting.

Finisar may require any proposed nominee to furnish such other information as it may reasonably required to determine the eligibility of such proposed nominee to serve as a director.

Shareholder Proposals (other than Nomination of Persons for Election as Directors) TheII-VIBy-Laws generally permit shareholders to bring business before an annual meeting of the shareholders if the shareholder intending to bring such business gives timely notice thereof in proper form.   To be timely, a shareholder’s written notice must be delivered to the corporate secretary no later than the close of business on the 120th day and no earlier than the close of business on the 150th day prior to the anniversary date of the preceding year’s annual meeting.   To be in proper form, a shareholder’s written notice must include (i) the name and address of the shareholder, (ii) the class and number of shares ofII-VI Common Stock that are beneficially owned by the shareholder and certain other specified interests or arrangements involving the shareholder, (iii) any other information relating to the shareholder that would be required to be disclosed in a proxy statement and form of proxy or other filings required to be made in connection with solicitations of proxies for the proposal pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder, (iv) a brief description of the business desired to be brought before the meeting, (v) the text of the proposal or business, (vi) any material interest of the shareholder in such business, and (vii) a description of all agreements between the shareholder and any other person in connection with the proposal of such business by the shareholder.   Under theII-VIBy-Laws, at any special meeting of the shareholders, only such business shall be conducted or considered, as shall have been properly brought before the meeting pursuant toII-VI’s notice of meeting. To be properly brought The Finisar Bylaws generally permit stockholders to bring business before an annual meeting of the stockholders if the stockholder intending to bring such business gives timely notice thereof in proper form.   To be timely, a stockholder’s written notice must be delivered to the corporate secretary no later than the close of business on the 90th day and no earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting of stockholders.   To be in proper form, a stockholder’s written notice must include (i) a brief description of the business desired to be brought before the meeting, (ii) the text of the proposal or business, (iii) the reasons for conducting such business at the meeting and any material interest in such business of such stockholder, (iv) a description of all agreements between such stockholder and any other person in connection with the proposal of such business by such stockholder, (v) the name and address of the stockholder, (vi) the class and number of shares of Finisar Common Stock that are beneficially owned by the stockholder and certain other specified interests or arrangements involving the shareholder, (vii) any other information relating to such person that is required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies for the proposal pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder, and (viii) certain representations by the stockholder as specified in the Finisar Bylaws.   Under the Finisar Bylaws, all business conducted at a special meeting of stockholders must have been brought before the meeting

	before a special meeting, proposals of business must be specified inII-VI’s notice of meeting given by or at the direction of theII-VI Board or otherwise properly brought before the special meeting by or at the direction of theII-VI Board.	pursuant to Finisar’s notice of meeting.
Limitation of Liability of Directors and Officers	Pennsylvania law provides that, if provided in a bylaw or articles provision adopted by shareholders, a director shall not be personally liable for monetary damages as such for any action taken, or any failure to take any action, unless (i) the director has breached or failed to perform the duties of his/her office and (ii) the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness, other than under criminal statutes and under federal, state and local laws imposing liability on directors for the payment of taxes. TheII-VIBy-Laws contain such a provision.	Delaware law provides that a corporation may limit or eliminate a director’s personal liability for monetary damages to the corporation or its stockholders for breach of fiduciary duty as a director, except for liability for: (i) any breach of the director’s duty of loyalty to such corporation or its stockholders; (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) willful or negligent violation of provisions of Delaware law governing payment of dividends and stock purchases or redemptions; or (iv) any transaction from which the director derived an improper personal benefit. Under the Finisar Charter, directors are not personally liable to Finisar or its stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by Delaware law.
Indemnification of Directors, Officers, Employees and Agents	Pennsylvania law authorizes a corporation to indemnify any director, officer, employee or agent who is or was a representative of, or serving at the request of, the corporation, so long as such person acted in good faith and with a reasonable belief that his or her actions were in the best interests, or not opposed to the best interests, of the corporation, and with respect to any criminal proceeding, such person had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under Pennsylvania law does not exist in the case of actions against a director or officer by or in the right of the corporation if the person otherwise	Under the Finisar Bylaws, Finisar will indemnify and hold harmless, to the fullest extent permitted by Delaware law, any person (and the heirs, executors or administrators of such person) who was or is a party or is threatened to be made a party to, or is threatened to be made a party to and is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director or officer of Finisar or is or was serving at the request of Finisar as a director or officer of another corporation, partnership, joint venture, trust or other enterprise (other than certain actions or

206

entitled to indemnification shall have been adjudged to be liable to the corporation unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for specified expenses.   Pennsylvania law states that the statutory rights of indemnification and advancement of expenses are not exclusive of any other rights to which a person might be entitled under any bylaw, agreement, vote of shareholders or disinterested directors, or otherwise, both as to the action in his or her official capacity and as to the action or proceeding in another capacity while holding that office. However, Pennsylvania law forbids indemnification to be made in any case where the act or failure to act giving rise to the claim is determined by a court to be willful misconduct or recklessness. A corporation’s articles of incorporation may not provide for indemnification in the case of willful misconduct or recklessness.   Under theII-VIBy-Laws,II-VI will indemnify its directors and officers and advance expenses (upon receipt of an undertaking by or on behalf of such director or officer to repay such expenses if it is ultimately determined that such director or officer is not entitled to be indemnified byII-VI) to the fullest extent permitted by Pennsylvania law (except thatII-VI is not obligated to indemnify or advance with respect to claims initiated by the director or officer) and permit, by action ofII-VI, indemnification and advancement of expenses to its employees and agents as determined byII-VI.   II-VI has entered into agreements with its directors and officers proceedings initiated by such person without the prior consent of the Finisar Board). The Finisar Bylaws also require the advancement of any such person’s expenses incurred in connection with any such proceeding in advance of its final disposition to the fullest extent authorized by Delaware law. The right to indemnification conferred in the Finisar Bylaws is a contract right.

207

	pursuant to whichII-VI has agreed to provide for the indemnification of and the advancing of expenses to each such indemnitee to the fullest extent permitted by law and as set forth in the applicable agreement, and, to the extent insurance is maintained, for the continued coverage of each such indemnitee underII-VI’s directors’ and officers’ liability insurance policies. Pennsylvania law provides mandatory indemnification for any director, officer, employee or agent who is or was a representative of, or serving at the request of, the corporation if he or she succeeds on the merits or otherwise in the defense of any claim or action or proceeding, or in defense of any claim, issue or matter therein. The corporation must indemnify him or her to the extent of his or her actual and reasonable expenses (including attorney’s fees) incurred in connection with the claim or action.
Appraisal Rights or Dissenters’ Rights	Under Pennsylvania law, unless the articles of incorporation orby-laws provide otherwise, shareholders of a Pennsylvania corporation generally are not entitled to dissenters’ rights if the shares that would otherwise give rise to such rights are (i) listed on a national securities exchange or (ii) held beneficially or of record by more than 2,000 persons, such as the shares ofII-VI Common Stock. The forgoing limitation does not apply to the right to dissenters’ rights in the case of “special treatment” described under “Description ofII-VI’s Capital Stock — Anti-Takeover Provisions — Pennsylvania State Law Provisions” beginning on page 194 of this joint proxy statement/prospectus. Neither theII-VI Charter nor theII-VIBy-Laws contain provisions in this regard.	Under Delaware law, stockholders of a Delaware corporation have the right, in certain mergers or consolidations to which the corporation is a party, to demand payment for the fair value of their shares pursuant to, and in compliance with procedures set forth in, Section 262 of the DGCL, except in connection with a merger or consolidation with respect to shares (i) listed on a national securities exchange or held of record by more than 2,000 holders and (ii) for which, pursuant to the plan of merger or consolidation, stockholders will receive only (a) shares or depository receipts of another corporation which at the date the merger or consolidation is completed will be either listed on a national securities exchange or held of record by more than 2,000 holders, (b) shares of stock or depositary receipts of the surviving corporation in the merger

208

or consolidation, (c) cash in lieu of fractional shares or (d) any combination of the foregoing. Delaware law also provides that, subject to certain exceptions, stockholders of a surviving corporation do not have appraisal rights in connection with a plan of merger if the merger did not require for its approval the vote of the surviving corporation’s stockholders. Stockholders also do not have appraisal rights in connection with certain “short-form” mergers between a parent corporation and wholly owned subsidiary corporation. Delaware law permits the certificate of incorporation of a Delaware corporation to provide for appraisal rights in mergers or consolidations in which appraisal rights are not otherwise available and in connection with amendments to the certificate of incorporation and sales of all or substantially all assets. The Finisar Charter contains no provisions giving rise to appraisal rights in such transactions.

Additionally, pursuant to Section 262 of the DGCL, if immediately before a merger or consolidation the shares of a class or series of stock of a corporation as to which appraisal rights are available were listed on a national securities exchange, the Delaware Court of Chancery must dismiss an appraisal proceeding as to all stockholders who assert appraisal rights unless (i) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (ii) the value of the consideration provided in the merger or consolidation for such total number of shares seeking appraisal exceeds $1 million, or (iii) the merger was approved pursuant to Section 253 or Section 267 of the DGCL.

At any time before the entry of judgment in the proceedings, the surviving corporation may pay to

209

		each stockholder entitled to appraisal an amount in cash, in which case interest will accrue thereafter as provided under Section 262 of the DGCL only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Delaware Court of Chancery and (2) interest theretofore accrued, unless paid at that time.
Dividends and Stock Repurchases	Subject to any rights of any outstanding series ofII-VI shares senior to the shares ofII-VI Common Stock, the holders ofII-VI Common Stock are entitled to such dividends as may be declared from time to time by theII-VI Board from funds available therefor.	Subject to the preferential rights of any holders of outstanding preferred stock or preference stock, holders of Finisar Common Stock are entitled to receive, to the extent permitted by law, such dividends as the Finisar Board may declare from time to time from funds available therefor.
Shareholder Vote on Fundamental or Extraordinary Corporate Transactions	Under Pennsylvania law, except in certain limited circumstances where a vote of shareholders is not required, or unless a higher vote is required in a corporation’s articles of incorporation, a plan of merger, a plan of asset transfer providing for the sale of all or substantially all of the assets of a corporation, or a plan of interest exchange, conversion, division or voluntary dissolution will be adopted upon receiving at a properly convened meeting the affirmative vote of a majority of the votes cast by all shareholders entitled to vote thereon and the affirmative vote of a majority of the votes cast in any required class vote. TheII-VI Charter does not contain provisions in this regard.	Under Delaware law, a sale, lease or exchange of all or substantially all of a Delaware corporation’s assets, an amendment to a corporation’s certificate of incorporation, a merger or consolidation of a corporation with another corporation or a dissolution of a corporation generally requires the affirmative vote of the Finisar Board and, with limited exceptions, the affirmative vote of a majority of the aggregate voting power of the outstanding stock entitled to vote on the transaction. The Finisar Charter provides that, notwithstanding any provision of law otherwise permitting a lesser vote, the affirmative vote of the holders of at leasttwo-thirds of the voting power of all of the then outstanding shares of the capital stock of Finisar entitled to vote generally in the election of directors, voting together as a single class, is required in order to amend or repeal certain provisions of the Finisar Charter relating to the management of the business and the conduct of the affairs of Finisar, special meetings and actions by written consent of Finisar stockholders, number of directors, classification of directors, filling of vacancies on the Finisar

210

		Board, removal of directors, approval requirements to amend the Finisar Charter and the Finisar Bylaws, and indemnification of directors and officers.
State Anti-Takeover Provisions	Under Subchapter E of Chapter 25 of the BCL, certain persons that acquire 20% or more of the voting power of a Pennsylvania target corporation must pay in cash the “fair value” for the shares held by the other shareholders of the corporation who object to the acquisition transaction.II-VI has not opted out of the applicability of Subchapter E of Chapter 25 of the BCL. Under Subchapter F of Chapter 25 of the BCL, a Pennsylvania corporation is prohibited from engaging in a “business combination” (as defined under the BCL) with an “interested shareholder” (defined generally to be any beneficial owner of 20% or more of the corporation’s voting shares), unless (i) the board of directors of such corporation approves the proposed transaction or approves the interested shareholder’s acquisition of shares that gave such person beneficial ownership of 20% of the shares entitled to vote in an election of directors of such corporation, in either case prior to the date on which the shareholder first becomes an interested shareholder (the “Share Acquisition Date”), (ii) the interested shareholder owns at least 80% of the shares of such corporation entitled to vote in an election of directors and, no earlier than three months after such interested shareholder reaches such 80% level, the holders of a majority of the remaining shares approve the proposed transaction and shareholders receive a minimum “fair price” for their shares (as set forth in the BCL) in the transaction and the other conditions of Subchapter F are met, (iii) holders of all outstanding common shares approve the transaction, (iv) no earlier than five	Finisar has not opted out of Section 203 of the DGCL, which provides that, if a person acquires 15% or more of the outstanding voting stock of a Delaware corporation, thereby becoming an “interested stockholder,” that person may not engage in certain “business combinations” with the corporation, including mergers, sales of 10% or more of the corporation’s assets, stock issuances or transfers and other transactions pursuant to which the interested stockholder’s proportionate share of the corporation’s stock increases, or pursuant to which the interested stockholder receives a financial benefit from the corporation (other than proportionately as a stockholder of the corporation), for a period of three years after becoming an interested stockholder unless one of the following exceptions applies: (i) the board of directors approved the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; (ii) upon consummation of the transaction that resulted in the person becoming an interested stockholder, such person owned at least 85% of the outstanding voting stock of the corporation, excluding, for purposes of determining the voting stock outstanding, voting stock owned by directors who are also officers and certain employee stock plans; or (iii) the transaction is approved by the board of directors and by the affirmative vote oftwo-thirds of the outstanding voting stock which is not owned by the interested stockholder. An “interested stockholder” also includes any affiliate or associate of the corporation who was the owner of

211

years after the Share Acquisition Date, a majority of the shares held by shareholders other than the interested shareholder and entitled to vote in an election of directors approve the transaction, or (v) no earlier than five years after the Share Acquisition Date, a majority of all the shares approve the transaction, all shareholders receive a minimum “fair price” for their shares (as set forth in the BCL) and the other conditions of Subchapter F are met.II-VI has not opted out of the applicability of Subchapter F of Chapter 25 of the BCL.   Under Subchapter G of Chapter 25 of the BCL, certain persons who acquire 20% or more, 33 1/3% or more, or 50% or more of the voting power of a Pennsylvania corporation for the first time lose the right to vote those “control” shares unless and until its voting rights are reinstated by the affirmative vote of at least (i) a majority of the disinterested voting shares and (ii) a majority of all voting shares of the corporation.II-VI has not opted out of the applicability of Subchapter G of Chapter 25 of the BCL. If the acquiring person does not seek such a vote, or if it does and it does not receive the necessary shareholder approval, the corporation may, within a24-month period, redeem the acquired shares at a market-based price.   Under Subchapter H of Chapter 25 of the BCL, certain persons that own 20% or more of a Pennsylvania corporation’s shares, or that has publicly announced an intention to acquire control of the corporation, must disgorge any profits it realizes on the sale of its shares to the corporation within 18 months of acquiring control status, including any forced sale pursuant to Subchapter G.II-VI has not opted out of the applicability of Subchapter H of Chapter 25 of the BCL. 15% or more of the outstanding voting stock within the three-year period prior to determining whether a person is an interested stockholder, and the affiliates and associates of such person.

212

Shareholder Rights Plan	Pennsylvania law expressly authorizes a corporation to adopt a shareholder rights plan, and provides that the fiduciary duty of directors does not require them to redeem, modify, or render inapplicable any such rights plan. II-VI currently has no shareholder rights plan. WhileII-VI has no present intention to adopt a shareholder rights plan, theII-VI Board retains the right to adopt such a plan at a future date pursuant to its exclusive authority to create and issue rights entitling the holders thereof to purchase fromII-VI shares of capital stock or other securities and to elect to repurchase, redeem, terminate or amend any such rights.	Although Delaware law does not include a statutory provision expressly authorizing stockholder rights plans, such rights plans have generally been found to be authorized by Delaware law and have been upheld by Delaware courts where they are adopted in response to a reasonably perceived threat to a Delaware corporation and its stockholders, and adopting such rights plans in response to such threat has been found to be reasonable in relation to the threat posed. Finisar does not currently have a stockholder rights plan, but the Finisar Board has the power under Delaware law and the Finisar Charter and the Finisar Bylaws to adopt a stockholder rights plan in the future, subject to its fiduciary duties.
Preemptive Rights	Under Pennsylvania law, shareholders of a corporation do not have preemptive rights to subscribe for or purchase any additional issue of stock or to any security convertible into such stock, unless such right is expressly included in the articles of incorporation. TheII-VI Charter does not provide holders of shares ofII-VI Common Stock with preemptive rights.	Under Delaware law, stockholders of a corporation do not have preemptive rights to subscribe for or purchase any additional issue of stock or to any security convertible into such stock, unless such right is expressly included in the certificate of incorporation. The Finisar Charter does not provide holders of shares of Finisar Common Stock with preemptive rights.
Duties of Directors	Under Pennsylvania law, the standard of conduct for directors is governed by statute and case law. Pennsylvania law requires that a director of a Pennsylvania corporation perform his or her duties: (i) in good faith, (ii) in a manner he or she reasonably believes to be in the best interests of the corporation, and (iii) with such care, including reasonable inquiry, skill and diligence, as a person of ordinary prudence would use under similar circumstances. In discharging their duties, directors may, in considering the best interests of their corporation, consider, among other things, to the extent they deem	Under Delaware law, the standard of conduct for directors of corporations is not statutory but is based on fiduciary duty principles developed by the Delaware courts. Directors of Delaware corporations owe a duty of loyalty and a duty of care to the corporation and its stockholders. The duty of loyalty requires directors to act with the sole purpose of advancing the best interests of the corporation and its stockholders, and the duty of care requires directors to act with due care in the process of decision-making and to act on an informed basis. Directors must also exercise due care in the other aspects

213

appropriate: (a) the effects of any action upon any or all groups affected by the action, including shareholders, employees, suppliers, customers and creditors of the corporation, and upon communities in which offices or other establishments of the corporation are located; (b) the short-term and long-term interests of the corporation; (c) the resources, intent and conduct (past, stated and potential) of any person seeking to acquire control of the corporation; and (d) all other pertinent factors. In considering the best interests of the corporation or the effects of any action, directors are not required to regard any corporate interest or the interests of the shareholders, or any other group affected by the action, as a dominant or controlling factor.   Under Pennsylvania law, the fiduciary duty of directors does not require them to take action (including under any of the anti-takeover laws) solely because of the effect that such action might have on a potential or proposed acquisition of control of the corporation, or on the consideration that might be offered or paid to shareholders in such an acquisition. of their responsibilities, including their delegation functions. The standard for due care is gross negligence. Directors owe fiduciary duties of loyalty and care to the corporation and its stockholders. Fiduciary duties are not owed tonon-stockholder constituencies such as customers and employees.

APPRAISAL RIGHTS

General

This section summarizes certain material provisions of Delaware law pertaining to appraisal rights. The following discussion, however, is not a full summary of the law pertaining to appraisal rights under the DGCL and is qualified in its entirety by the full text of Section 262 of the DGCL, a copy of which is attached asAnnex D to this joint proxy statement/prospectus and incorporated by reference herein.The following discussion does not constitute any legal or other advice, nor does it constitute a recommendation as to whether or not a Finisar stockholder should exercise its right to seek appraisal under Section 262 of the DGCL.For purposes of appraisal rights available to Finisar stockholders, and except as otherwise provided in Section 262 of the DGCL or in this section of this joint proxy statement/prospectus, all references in Section 262 of the DGCL, and in this section of this joint proxy statement/prospectus, to “stockholder” are to the record holder of the shares of Finisar Common Stock except where otherwise noted.

Pursuant to Section 262 of the DGCL, a Finisar stockholder who chooses the Stock Election Consideration for his, her or its shares of Finisar Common Stock, but receivesII-VI Common Stock and cash for such shares through the proration adjustment mechanism due to oversubscription of the Stock Election Consideration, will be entitled to appraisal rights for such shares if such stockholder otherwise complies with the requirements of Section 262 of the DGCL.APPRAISAL RIGHTS WILL NOT BE AVAILABLE TO FINISAR STOCKHOLDERS WHO FAIL TO MAKE AN ELECTION AND RECEIVE THE MIXED ELECTION CONSIDERATION OR TO FINISAR STOCKHOLDERS WHO CHOOSE THE CASH ELECTION CONSIDERATION OR THE MIXED ELECTION CONSIDERATION. THE ONLY CIRCUMSTANCES UNDER WHICH A FINISAR STOCKHOLDER MAY BE ENTITLED TO APPRAISAL RIGHTS IS IF SUCH STOCKHOLDER CHOOSES THE STOCK ELECTION CONSIDERATION BUT RECEIVES A COMBINATION OF CASH ANDII-VI COMMON STOCK THROUGH THE PRORATION MECHANISMS. Finisar stockholders who are entitled to appraisal rights and wish to exercise the right to seek an appraisal of their shares (i) must not vote in favor of the Merger Proposal nor consent thereto in writing, (ii) must continuously hold their shares of Finisar Common Stock through the effective date of the Merger, (iii) must deliver to Finisar a written demand for appraisal prior to the date of the Finisar Special Meeting and (iv) must otherwise comply with the applicable requirements of Section 262 of the DGCL. Appraisal rights is a process by which a stockholder may seek the “fair value” of their shares of Finisar Common Stock in cash, together with interest, if any, as determined by the Delaware Court of Chancery, if the Merger is completed. The “fair value” of shares of Finisar Common Stock as determined by the Delaware Court of Chancery could be greater than, the same as, or less than the value of the Merger Consideration that Finisar stockholders would otherwise be entitled to receive under the terms of the Merger Agreement.

Under Section 262 of the DGCL, because Finisar stockholders are being asked to adopt the Merger Agreement at a meeting of stockholders, not less than 20 days prior to the Finisar Special Meeting to adopt such agreement, Finisar must notify each stockholder who was a Finisar stockholder on the Finisar Record Date and who is entitled to exercise appraisal rights that appraisal rights are available and include in the notice a copy of Section 262 of the DGCL.This joint proxy statement/prospectus constitutes the required notice, and the copy of Section 262 of the DGCL is attached asAnnex D to this joint proxy statement/prospectus.

A HOLDER OF FINISAR COMMON STOCK WHO WISHES TO EXERCISE APPRAISAL RIGHTS OR WHO WISHES TO PRESERVE THE RIGHT TO DO SO SHOULD REVIEW THE FOLLOWING SUMMARY ANDANNEX D CAREFULLY. FAILURE TO COMPLY WITH THE PROCEDURES OF SECTION 262 OF THE DGCL IN A TIMELY AND PROPER MANNER MAY RESULT IN THE LOSS OF APPRAISAL RIGHTS. BECAUSE OF THE COMPLEXITY OF THE PROCEDURES FOR EXERCISING THE RIGHT TO SEEK APPRAISAL, IF A HOLDER OF FINISAR COMMON STOCK WISHES TO EXERCISE HIS, HER OR ITS APPRAISAL RIGHTS, THE HOLDER IS URGED TO CONSULT WITH ITS OWN LEGAL AND FINANCIAL ADVISORS IN CONNECTION

215

WITH COMPLIANCE UNDER SECTION 262 OF THE DGCL. A FINISAR STOCKHOLDER WHO LOSES HIS, HER OR ITS APPRAISAL RIGHTS WILL BE ENTITLED TO RECEIVE THE MIXED ELECTION CONSIDERATION FOR EACH SHARE OF FINISAR COMMON STOCK.

How to Exercise and Perfect Your Appraisal Rights

If you are a Finisar stockholder and wish to exercise the right to seek an appraisal of your shares of Finisar Common Stock, you must comply with ALL of the following:

• you must not vote in favor of or otherwise consent in writing to, the adoption of the Merger Proposal. Because a proxy that is signed and submitted but does not otherwise contain voting instructions will, unless revoked, be voted in favor of the Merger Proposal, if you submit your vote instructions by proxy and wish to exercise your appraisal rights, you must vote against the adoption of the Merger Proposal or abstain from voting your shares;

• you must deliver to Finisar a written demand for appraisal before the taking of the vote on the Merger Proposal at the Finisar Special Meeting, and such demand must reasonably inform Finisar of your identity and your intention to demand appraisal of your shares of Finisar Common Stock. The written demand for appraisal must be in addition to and separate from any proxy or vote;

• you must not choose to receive the Cash Election Consideration, the Mixed Election Consideration or fail to make an election at all. The only Finisar stockholders who will be entitled to seek appraisal rights are stockholders who choose to receive the Stock Election Consideration, but receive a mix of cash andII-VI Common Stock through the proration mechanisms due to an oversubscription of the Stock Election Consideration;

• you must continuously hold your shares of Finisar Common Stock from the date of making the demand through the effective date of the Merger. You will lose your appraisal rights if you transfer the shares before the Effective Time; and

• you, another Finisar stockholder, a beneficial owner of Finisar Common Stock or the Surviving Corporation must file a petition in the Delaware Court of Chancery requesting a determination of the fair value of the shares of Finisar Common Stock within 120 days after the effective date of the Merger. The Surviving Corporation is under no obligation to file any such petition in the Delaware Court of Chancery and has no intention of doing so. Accordingly, it is the obligation of Finisar stockholders or a beneficial owner of Finisar Common Stock to initiate all necessary action to perfect their appraisal rights in respect of shares of Finisar Common Stock within the time prescribed in Section 262 of the DGCL.

In addition, the Delaware Court of Chancery will dismiss appraisal proceedings as to all shares of Finisar Common Stock if, immediately before the Merger, such shares were listed on a national securities exchange unless (i) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of Finisar Common Stock eligible for appraisal or (ii) the value of the consideration provided in the Merger for such total number of shares entitled to appraisal exceeds $1 million. We refer to these conditions as the “ownership thresholds.” Because Finisar Common Stock is listed on a national securities exchange and is expected to continue be listed on such exchange immediately before the Merger, at least one of the ownership thresholds must be met in order for Finisar stockholders to be entitled to seek appraisal with respect to such shares of Finisar Common Stock.

Voting, in person or by proxy, against, abstaining from voting on or failing to vote on the Merger Proposal will not constitute a written demand for appraisal as required by Section 262 of the DGCL. The written demand for appraisal is in addition to and separate from any proxy or vote.

216

Who May Exercise Appraisal Rights

Only a holder of record of shares of Finisar Common Stock issued and outstanding immediately prior to the Effective Time may assert appraisal rights for the shares of Finisar Common Stock registered in that holder’s name. Such stockholders also must have made an election to receive the Stock Election Consideration but received a mix of cash andII-VI Common Stock through the proration mechanisms due to an oversubscription of the Stock Election Consideration. A demand for appraisal must be executed by or on behalf of the stockholder of record. The demand should set forth, fully and correctly, the stockholder’s name as it appears on the stock certificates (or in the stock ledger). The demand must reasonably inform Finisar of the identity of the stockholder and that the stockholder intends to demand appraisal of his, her or its Finisar Common Stock. Beneficial owners who do not also hold their shares of Finisar Common Stock of record may not directly make appraisal demands to Finisar. The beneficial owner must, in such cases, have the holder of record, such as a bank, broker or other nominee, submit the required demand in respect of those shares of Finisar Common Stock of record. A holder of record, such as a bank, broker or other nominee, who holds shares of Finisar Common Stock as a nominee or intermediary for others may exercise his, her or its right of appraisal with respect to the shares of Finisar Common Stock held for one or more beneficial owners, while not exercising this right for other beneficial owners. In that case, the written demand should state the number of shares of Finisar Common Stock as to which appraisal is sought. Where no number of shares of Finisar Common Stock is expressly mentioned, the demand will be presumed to cover all shares of Finisar Common Stock held in the name of the holder of record.

IF YOU HOLD YOUR SHARES IN BANK OR BROKERAGE ACCOUNTS OR OTHER NOMINEE FORMS AND YOU WISH TO EXERCISE APPRAISAL RIGHTS, YOU ARE URGED TO CONSULT WITH YOUR BANK, BROKER OR OTHER NOMINEE TO DETERMINE THE APPROPRIATE PROCEDURES FOR THE BANK, BROKERAGE FIRM OR OTHER NOMINEE TO MAKE A DEMAND FOR APPRAISAL OF THOSE SHARES. IF YOU HAVE A BENEFICIAL INTEREST IN SHARES HELD OF RECORD IN THE NAME OF ANOTHER PERSON, SUCH AS A NOMINEE OR INTERMEDIARY, YOU MUST ACT PROMPTLY TO CAUSE THE HOLDER OF RECORD TO FOLLOW PROPERLY AND IN A TIMELY MANNER THE STEPS NECESSARY TO PERFECT YOUR APPRAISAL RIGHTS. IF YOU HOLD YOUR SHARES THROUGH A BANK OR BROKERAGE WHO IN TURN HOLDS THE SHARES THROUGH A CENTRAL SECURITIES DEPOSITORY NOMINEE, SUCH AS THE DEPOSITORY TRUST COMPANY, A DEMAND FOR APPRAISAL OF SUCH SHARES MUST BE MADE BY OR ON BEHALF OF THE DEPOSITORY NOMINEE AND MUST IDENTIFY THE DEPOSITORY NOMINEE AS THE HOLDER OF RECORD.

If you own shares of Finisar Common Stock jointly with one or more other persons, as in a joint tenancy or tenancy in common, demand for appraisal must be executed by or for you and all other joint owners. An authorized agent, including an agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the holder or holders of record and expressly disclose the fact that, in exercising the demand, such person is acting as agent for the holder or holders of record.

If you elect to exercise appraisal rights under Section 262 of the DGCL, you should mail or deliver a written demand to:

Finisar Corporation

Sunnyvale, California 94089

Attention: Corporate Secretary

The Surviving Corporation’s Actions After Completion of the Merger

If the Merger is consummated, the Surviving Corporation will give written notice of the effective date of the Merger within 10 days after the effective date to Finisar stockholders who did not vote in favor of the Merger

217

Proposal and who made a written demand for appraisal in accordance with Section 262 of the DGCL. At any time within 60 days after the effective date of the Merger, any Finisar stockholder that made a demand for appraisal but did not commence an appraisal proceeding or join in such a proceeding as a named party will have the right to withdraw the demand and to accept the Mixed Election Consideration in accordance with the Merger Agreement for each of his, her or its shares of Finisar Common Stock, but after such60-day period a demand for appraisal may be withdrawn only with the written approval of the Surviving Corporation. Within 120 days after the effective date of the Merger, either the record holder or a beneficial owner of Finisar Common Stock, provided such person has complied with the requirements of Section 262 of the DGCL and is otherwise entitled to appraisal rights, or the Surviving Corporation may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery, with a copy served on the Surviving Corporation in the case of a petition filed by a record holder or a beneficial owner of Finisar Common Stock, demanding an appraisal of the value of the shares of Finisar Common Stock held by all stockholders who have properly demanded appraisal. The Surviving Corporation is under no obligation to file an appraisal petition and has no intention of doing so. If you desire to have your shares appraised, you should initiate any petitions necessary for the perfection of your appraisal rights within the time periods and in the manner prescribed in Section 262 of the DGCL.

Within 120 days after the effective date of the Merger, any record holder or beneficial owner of Finisar Common Stock who has complied with the provisions of Section 262 of the DGCL will be entitled to receive from the Surviving Corporation, upon written request, a statement setting forth the aggregate number of shares of Finisar Common Stock not voted in favor of the adoption of the Merger Proposal and with respect to which Finisar has received demands for appraisal, and the aggregate number of holders of those shares. The Surviving Corporation must mail this statement to you within the later of (a) 10 days after receipt by the Surviving Corporation of the request therefor or (b) 10 days after expiration of the period for delivery of demands for appraisal.

If a petition for appraisal is duly filed by you or another holder of record or beneficial owner of Finisar Common Stock who has properly exercised his, her or its appraisal rights in accordance with the provisions of Section 262 of the DGCL, and a copy of the petition is served on the Surviving Corporation, the Surviving Corporation will then be obligated, within 20 days after receiving service of a copy of the petition, to file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreements as to the value of their shares have not been reached by the Surviving Corporation. The Register in Chancery, if so ordered by the Delaware Court of Chancery, will give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the Surviving Corporation and to the stockholders shown on such verified list at the addresses therein stated. Such notice will also be given by one (1) or more publications at least one (1) week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Delaware Court of Chancery deems advisable. The forms of the notices by mail and by publication will be approved by the Delaware Court of Chancery, and the costs thereof will be borne by the Surviving Corporation. At the hearing on the petition, the Delaware Court of Chancery will then determine which Finisar stockholders are entitled to appraisal rights and may require the Finisar stockholders demanding appraisal who hold certificated shares to submit their stock certificates to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings, and the Delaware Court of Chancery may dismiss the proceedings as to any Finisar stockholder who fails to comply with this direction. Assuming the shares of Finisar Common Stock remain listed on a national securities exchange immediately before the Merger, the Delaware Court of Chancery will also dismiss proceedings as to all Finisar stockholders if neither of the ownership thresholds described above is met. After the Delaware Court of Chancery determines the stockholders entitled to an appraisal, the appraisal proceeding will be conducted in accordance with the rules of the Delaware Court of Chancery, including any rules specifically governing appraisal proceedings. The Delaware Court of Chancery will thereafter determine the fair value of the shares of Finisar Common Stock, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with interest, if any. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest from the effective date of the Merger through the date of payment of the judgment will be compounded quarterly

218

and will accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the Merger and the date of payment of the judgment. However, the Surviving Corporation has the right, at any point prior to the Delaware Court of Chancery’s entry of judgment in the proceedings, to make a voluntary cash payment to each stockholder entitled to appraisal. If the Surviving Corporation makes such a voluntary cash payment, interest will accrue thereafter only on the sum of (i) the difference, if any, between the amount paid by the Surviving Corporation in such voluntary cash payment and the fair value of the shares as determined by the Delaware Court of Chancery and (ii) interest accrued before such voluntary cash payment, unless paid at that time. When the value is determined, the Delaware Court of Chancery will direct the payment of such value, with interest thereon, if any, to the Finisar stockholders entitled to receive the same, forthwith in the case of holders of uncertificated stock or upon surrender of their stock certificates in the case of holders of shares represented by certificates.

In determining the fair value, the Delaware Court of Chancery is required to take into account all relevant factors. InWeinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company.” The Delaware Supreme Court has stated that, in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other factors which were known or which could be ascertained as of the date of the merger which throw any light on future prospects of the merged corporation. Section 262 of the DGCL provides that fair value is to be “exclusive of any element of value arising from the accomplishment or expectation of the merger.” InCede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a “narrow exclusion [that] does not encompass known elements of value,” but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. InWeinberger, the Delaware Supreme Court construed Section 262 of the DGCL to mean that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered.”

An opinion of an investment banking firm as to the fairness from a financial point of view of the consideration payable in a merger is not an opinion as to, and does not in any manner address, fair value under Section 262 of the DGCL. The fair value of shares of Finisar Common Stock as determined under Section 262 of the DGCL could be greater than, the same as, or less than the value of the Merger Consideration.II-VI does not anticipate offering more than the Merger Consideration to any Finisar stockholder exercising appraisal rights and reserves the rights to make a voluntary cash payment pursuant to subsection (h) of Section 262 of the DGCL and to assert, in any appraisal proceeding, that, for purposes of Section 262 of the DGCL, the “fair value” of a share of Finisar Common Stock is less than the Merger Consideration. No representation is made as to the outcome of the appraisal of fair value as determined by the Delaware Court of Chancery.

If no party files a petition for appraisal within 120 days after the effective date of the Merger or, assuming the shares of Finisar Common Stock remain listed on a national securities exchange immediately before the Merger, if neither of the ownership thresholds above has been satisfied, then all Finisar stockholders will lose the right to an appraisal, and will instead receive the Mixed Election Consideration for each of Finisar Common Stock as described in the Merger Agreement, without interest thereon, less any withholding taxes.

The Delaware Court of Chancery may determine the costs of the appraisal proceeding and may allocate those costs to the parties as the Delaware Court of Chancery determines to be equitable under the circumstances. Each Finisar stockholder party to the appraisal proceeding is responsible for his, her or its own attorneys’ fees and expert witnesses’ fees and expenses, although, upon application of a stockholder, the Delaware Court of Chancery may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts, to be charged pro rata against the value of all shares of Finisar Common Stock entitled to appraisal.

219

If you have duly demanded an appraisal in compliance with Section 262 of the DGCL you may not, on or after the effective date of the Merger, vote the shares of Finisar Common Stock subject to the demand for any purpose or receive any dividends or other distributions on those shares, except dividends or other distributions payable to holders of record of Finisar Common Stock as of a record date prior to the effective date of the Merger.

If you have not commenced an appraisal proceeding or joined such a proceeding as a named party you may withdraw a demand for appraisal and accept the Mixed Election Consideration for each of your shares of Finisar Common Stock by delivering a written withdrawal of the demand for appraisal and an acceptance of the Merger to the Surviving Corporation, except that any attempt to withdraw made more than 60 days after the effective date of the Merger will require written approval of the Surviving Corporation, and no appraisal proceeding in the Delaware Court of Chancery will be dismissed as to any stockholder without the approval of the Delaware Court of Chancery. Such approval may be conditioned on the terms the Delaware Court of Chancery deems just; provided, however, that this provision will not affect the right of any Finisar stockholder that has made an appraisal demand but who has not commenced an appraisal proceeding or joined such proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered in the Merger within 60 days after the effective date of the Merger. If you fail to perfect, successfully withdraw your demand for appraisal, or otherwise lose your appraisal rights, each of your shares of Finisar Common Stock will be converted into the right to receive the Mixed Election Consideration, without interest thereon, less any withholding taxes.

Failure to follow the steps required by Section 262 of the DGCL for perfecting appraisal rights may result in the loss of your appraisal rights. In that event, you will be entitled to receive the Mixed Election Consideration for each of your shares of Finisar Common Stock in accordance with the Merger Agreement. In view of the complexity of the provisions of Section 262 of the DGCL, if you are a Finisar stockholder and are considering exercising your appraisal rights under the DGCL, you are urged to consult your own legal and financial advisor.

THE PROCESS OF DEMANDING AND EXERCISING APPRAISAL RIGHTS REQUIRES COMPLIANCE WITH THE PREREQUISITES OF SECTION 262 OF THE DGCL. IF YOU WISH TO EXERCISE YOUR APPRAISAL RIGHTS, YOU ARE URGED TO CONSULT WITH YOUR OWN LEGAL AND FINANCIAL ADVISORS IN CONNECTION WITH COMPLIANCE UNDER SECTION 262 OF THE DGCL. TO THE EXTENT THERE ARE ANY INCONSISTENCIES BETWEEN THE FOREGOING SUMMARY AND SECTION 262 OF THE DGCL, THE DGCL WILL GOVERN.

SHAREHOLDER PROPOSALS

Finisar Stockholder Proposals

If the Merger is completed on the expected timetable, Finisar does not intend to hold a 2019 annual meeting for its stockholders. If, however, the Merger is not completed on the expected timetable or at all and the Finisar 2019 annual meeting is held, Finisar stockholder proposals may be included in Finisar’s proxy materials for an annual meeting so long as they are provided to Finisar on a timely basis and satisfy the other conditions set forth in applicable SEC rules. For a stockholder proposal to be included in Finisar’s proxy materials for its 2019 annual meeting of stockholders, the proposal (in addition to compliance with applicable SEC rules) must be received at Finisar’s principal executive offices, addressed to the Corporate Secretary, not later than March 26, 2019. Submitting a stockholder proposal does not guarantee that Finisar will include it in Finisar’s proxy statement. Finisar’s Nominating and Governance Committee reviews all stockholder proposals and makes recommendations to the Finisar Board for actions on such proposals. For information on qualifications of director nominees considered by Finisar’s Nominating and Governance Committee, see the “Corporate Governance” section of Finisar’s definitive proxy statement for its 2018 annual meeting of stockholders.

In addition, the Finisar Bylaws establish an advance notice procedure for Finisar stockholders who wish to present a proposal before an annual meeting of Finisar stockholders but do not intend for the proposal to be included in Finisar’s proxy statement. The Finisar Bylaws provide that in order for business to be properly brought before a meeting by a Finisar stockholder, such stockholder must have given timely notice thereof in writing to Finisar’s Corporate Secretary and provided certain information specified in the Finisar Bylaws. To be timely, a stockholder proposal must be received at Finisar’s principal executive offices not earlier than the close of business on the 120th

221

day nor later than the close of business on the 90th day prior to the first anniversary of the preceding year’s annual meeting of Finisar’s stockholders; except that in the event that the date of the annual meeting is more than 30 days before or more than 70 days after such anniversary date, notice by the Finisar stockholder must be so delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made by Finisar. Finisar will not entertain any proposals at an annual meeting that do not meet the requirements set forth in the Finisar Bylaws. The Finisar Bylaws are posted on Finisar’s website at http://investor.finisar.com/corporate-governance. To request a copy of the Finisar Bylaws, Finisar stockholders should contact Finisar’s Corporate Secretary.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and annual reports with respect to two or more shareholders sharing the same address by delivering a single proxy statement or annual report, as applicable, addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders and cost savings for companies.

If any Dissenting Stockholder shall have failed to perfect or shall have effectively withdrawn or lost such right, such Dissenting Stockholder’s shares of Company Common Stock shall thereupon be treated as if they had been converted into and became exchangeable for the right to receive, as of the Effective Time, the Mixed Election Consideration for each such share of Company Common Stock, in accordance withSection 2.01 (so long as such Dissenting Stockholder shall comply with the procedures inSection 2.02), without any interest thereon and less any applicable withholding taxes. The Company shall give Parent (i) prompt notice of any written demands for appraisal of any shares of Company Common Stock, attempted withdrawals of such demands, notices and any other instruments received by the Company relating to stockholders’ rights of appraisal, in each case, prior to the Effective Time, and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent (which shall not be unreasonably withheld, conditioned or delayed), make any payment with respect to any such demands for appraisal of any shares or settle or offer to settle any such demands.

Section 2.02Payment for Securities; Surrender of Certificates.

(a)Paying Agent. Promptly following the date hereof, Parent shall select and engage a national recognized bank or trust company as paying agent (who is reasonably acceptable to the Company) (the “Paying Agent”). At or immediately following the Effective Time, Parent shall deposit, or shall cause to be deposited, with such Paying Agent, for the benefit of the holders of Shares, (i) certificates representing the shares of Parent Common Stock to be issued as Stock Consideration (or appropriate alternative arrangements shall be made by Parent if uncertificated shares of Parent Common Stock will be issued) and (ii) a cash amount in immediately available funds equal to the aggregate Cash Consideration (the “Exchange Fund”). For the avoidance of doubt, the Exchange Fund deposited with the Paying Agent at or immediately following the Effective Time shall include the portion of the Cash Consideration and the shares of Parent Common Stock that would otherwise be payable to the Dissenting Stockholders in respect of their Dissenting Stockholder Shares.

(b)Procedures for Surrender.

(i)Certificates. Promptly after the Effective Time (but in no event later than two Business Days after the Effective Time), Parent shall cause the Paying Agent to mail to each holder of record (as of immediately prior to the Effective Time) of a Certificate whose Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement: (A) a letter of transmittal in customary form, reasonably acceptable to Parent and the Company (“Letter of Transmittal”), which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent, and shall otherwise be in such form and have such other provisions as Parent may reasonably specify after consultation with the Company; and (B) instructions for effecting the surrender of the Certificates in exchange for the Merger Consideration payable in respect thereof pursuant to the provisions of thisArticle II (or affidavit of loss in lieu of such Certificates as provided inSection 2.02(g)). Upon surrender of Certificates for cancellation (or delivery of an affidavit of loss in lieu of such Certificates as provided inSection 2.02(g)) to the Paying Agent, and upon delivery of a Letter of Transmittal, duly executed and in proper form with respect to such Certificates, and such other

A-5

documents as may reasonably be required by the Paying Agent, the holder of such Certificates shall be entitled to receive in exchange therefor (x) the Merger Consideration into which such shares of Company Common Stock have been converted pursuant toSection 2.01 (subject to the Election with respect to such shares of Company Common Stock and after giving effect to any required Tax withholdings as provided inSection 2.02(f)) and (y) any cash in lieu of fractional shares that the holder has the right to receive pursuant toSection 2.02(b)(v) (the “Fractional Share Consideration”). Any surrendered Certificate shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates. Until surrendered as contemplated hereby, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration and the Fractional Share Consideration, as applicable, as contemplated by this Agreement, except for Certificates representing Dissenting Stockholder Shares, which shall represent the right to receive payment of the fair value of such Shares in accordance with and to the extent provided by Section 262 of the DGCL.

(ii)Book-Entry Shares. Any holder of Book-Entry Shares whose Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement shall not be required to deliver a Certificate or an executed Letter of Transmittal to the Paying Agent to receive the Merger Consideration that such holder is entitled to receive pursuant to this Agreement. In lieu thereof, each such holder shall, upon receipt by the Paying Agent of an “agent’s message” (or such other evidence, if any, of surrender as the Paying Agent may reasonably request) be entitled to receive in exchange therefor (x) the Merger Consideration into which such shares of Company Common Stock have been converted pursuant toSection 2.01(b) (subject to the Election with respect to such shares of Company Common Stock and after giving effect to any required Tax withholdings as provided inSection 2.02(f)) and (y) the Fractional Share Consideration. No interest will be paid or accrued on any amount payable upon due surrender of Book-Entry Shares. Until paid or surrendered as contemplated hereby, each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration and the Fractional Share Consideration, as applicable, as contemplated by this Agreement, except for Book-Entry Shares representing Dissenting Stockholder Shares, which shall be deemed to represent the right to receive payment in accordance with and to the extent provided by Section 262 of the DGCL.

(iii)Transfer of Shares. If payment of the Merger Consideration or the Fractional Share Consideration is to be made to a person other than the person in whose name any surrendered Certificate or a transferred Book-Entry Share is registered, it shall be a condition precedent of such payment that (i) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer or the Book-Entry Share shall have been properly transferred, and (ii) the person requesting such payment shall have paid any transfer and other similar Taxes required by reason of the payment of the Merger Consideration and the Fractional Share Consideration, as applicable, to a person other than the registered holder of the Certificate or Book-Entry Share so surrendered and shall have established to the satisfaction of the that such Taxes either have been paid or are not required to be paid.

(iv)Distributions with Respect to Unexchanged Shares of Parent Common Stock. No dividends or other distributions declared or made after the Effective Time with respect to shares of Parent Common Stock with a record date after the Effective Time will be paid to the holder of any unsurrendered Certificate or Book-Entry Share with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of any fractional shares will be paid to any such holder, until the holder of such Certificate or Book-Entry Share surrenders such Certificate or Book-Entry Share. Subject to the effect of escheat, Tax or other applicable laws, following surrender of any such Certificate or Book-Entry Share, the holder of the Certificate or Book-Entry Share representing whole shares of Parent Common Stock issued in exchange therefor will be paid, without interest, (i) promptly, the amount of dividends or other distributions with a record date after the Effective Time and theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such whole shares of Parent Common Stock.

A-6

(v)No Fractional Shares. No fractional shares of Parent Common Stock shall be issued in the Merger, but in lieu thereof each former holder of Shares otherwise entitled to a fractional share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock issuable to such holder) will be entitled to receive, from the Paying Agent in accordance with the provisions of thisSection 2.02(b)(v), a cash payment (rounded to the nearest whole cent) in lieu of such fractional share of Parent Common Stock in an amount equal to the product of (i) such fraction, multiplied by (ii) the volume weighted average trading price of Parent Common Stock on the National Association of Securities Dealers Automated Quotations exchange (“NASDAQ”) for the five (5) consecutive trading days ending on the trading day immediately preceding the Closing Date.

(vi)Election. Each holder of record of Shares (not including the Excluded Shares or the Dissenting Stockholder Shares, but including holders of Participating RSUs and Participating ESPP Holders (each, a “Holder”) shall have the right, subject to the limitations set forth in thisArticle II, to submit an Election in accordance with thisSection 2.02(b)(vi) on or prior to the Election Deadline. The Company shall not waive the Election Deadline unless such Election Deadline is waived with respect to all Holders, the new election deadline is publicly disclosed by the Company to all Holders on a date agreed to by Parent, and Parent has otherwise given its prior written consent (not to be unreasonably withheld, conditioned or delayed) to such waiver. “Election Deadline” means 5:00 p.m. New York time on the date which the parties shall agree is as near as practicable to two (2) Business Days preceding the Closing Date. The parties shall cooperate to issue a press release reasonably satisfactory to each of them announcing the date of the Election Deadline not more than fifteen (15) Business Days before, and at least five (5) Business Days prior to, the Election Deadline.

(A) Each Holder may specify in a request made in accordance with the provisions of thisSection 2.02(b)(vi) (an “Election”) whether such Holder desires to make a (i) Mixed Election, (ii) Cash Election, or (iii) Stock Election, in each case with respect to all the Shares held by such Holder (including with respect to Participating RSUs and Company ESPP Rights). For the avoidance of doubt, an Election made by any Holder shall apply to all the Shares (including with respect to Participating RSUs and Company ESPP Rights) held by such Holder. If any Holder attempts to apply an Election to only a portion of such Holder’s Shares (including with respect to Participating RSUs and Company ESPP Rights), the portion of such Holder’s Shares (including with respect to Participating RSUs and Company ESPP Rights) with respect to which Holder did not attempt to make an Election shall be treated as if such Holder made a Mixed Election.

(B) Parent shall prepare a form of election that is reasonably acceptable to the Company (the “Form of Election”), which shall include the transmittal materials contemplated bySection 2.02(b) and Parent shall mail, or shall cause the Paying Agent to mail and deliver, together with the Joint Proxy Statement, the Form of Election to Holders as of the record date for notice of the Company Special Meeting not less than twenty (20) Business Days prior to the anticipated Election Deadline (the period between such mailing and the Election Deadline, the “Election Period”). Parent shall make available one or more Forms of Election as may reasonably be requested from time to time by all persons who become Holders during the period following the record date for the Company Special Meeting and prior to the Election Deadline.

(C) Any Election shall have been made properly only if the Paying Agent shall have received, by the Election Deadline, (i) a Form of Election properly completed and signed and (ii) the properly completed and executed documents required to be delivered by such Holder pursuant to the other provisions of thisSection 2.02. Any Holder (including with respect to Participating RSUs and the Company ESPP Rights) that does not make a valid Election by the Election Deadline shall be deemed to have made a Mixed Election.

(D) Any Holder may, at any time during the Election Period, revoke his or her or its Election by written notice to the Paying Agent prior to the Election Deadline, together with a properly completed and signed revised Form of Election. Any subsequent transfer of such Holder’s Shares (including with

A-7

respect to Participating RSUs and Company ESPP Rights) after such Holder has made an Election shall automatically revoke such Election (and such subsequent transferee may make a new Election pursuant to and if permitted by the terms of thisSection 2.02(b)(vi)). Notwithstanding anything to the contrary in this Agreement, all Elections shall be automatically deemed revoked upon receipt by the Paying Agent of written notification from the Company or Parent that this Agreement has been terminated in accordance withArticle VII. The Paying Agent shall have reasonable discretion to determine if any Election is not properly made, changed or revoked with respect to any Shares, including with respect to Participating RSUs and Company ESPP Rights (none of the Company, Parent, Merger Sub or the Paying Agent being under any duty to notify any Holder of any applicable defect). In the event the Paying Agent makes a reasonable determination that an Election was not properly made (including as a result of the Paying Agent not receiving an Election by the Election Deadline), such Election shall be deemed to be ineffective, and the Shares covered by such Election shall, for purposes hereof, be deemed to be Mixed Consideration Shares.

(c)No Further Ownership Rights in Company Common Stock; Closing of Transfer Books. As of the Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Company of the Shares that were outstanding immediately prior to the Effective Time, other than registrations of transfers to reflect, with customary settlement procedures, trades effected prior to the Effective Time. The Merger Consideration paid in accordance with the terms of thisArticle II upon surrender of any Shares shall be deemed to have been paid in full satisfaction of all rights pertaining to such Shares. From and after the Effective Time, the holders of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided for herein or by applicable law. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation, Parent or the Paying Agent for any reason, they shall be cancelled and, subject to the procedures set forth inSection 2.02(b), exchanged as provided in thisArticle II, except as otherwise required by law.

(d)Termination of Exchange Fund; Abandoned Property. Any portion of the Exchange Fund (including any interest or other income received by the Paying Agent with respect to all of the funds made available to it) that remains undistributed to the holders of the Shares for one (1) year after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of the Shares who have not theretofore complied with thisArticle II shall thereafter look only to the Surviving Corporation as general creditor thereof (subject to abandoned property, escheat and other similar laws) for payment of their claim for Merger Consideration.

(e)No Liability. Notwithstanding anything to the contrary inSection 2.02(d), none of Parent, Merger Sub, the Surviving Corporation, or the Paying Agent or any of their respective directors, officers, employees and agents shall be liable to any holder of a Share for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate (or affidavits of loss in lieu thereof as provided inSection 2.02(g)) shall not have been surrendered prior to the date on which the Merger Consideration represented by such Certificate would otherwise escheat to or become the property of any Governmental Authority, any such Merger Consideration shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(f)Withholding Rights. Notwithstanding anything herein to the contrary, each of Parent, Merger Sub, the Surviving Corporation and the Paying Agent, as applicable, shall be entitled to deduct and withhold from any consideration payable pursuant to, or in accordance with, this Agreement to any person such amounts as Parent, Merger Sub, the Surviving Corporation, or the Paying Agent, as applicable, are required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”) or any other provision of applicable federal, state, local or foreign Tax law. To the extent that amounts are so deducted and withheld by Parent, Merger Sub, the Surviving Corporation, or the Paying Agent, as the case may be, such deducted and withheld amounts shall be (i) remitted by Parent, Merger Sub, the Surviving Corporation,

A-8

or the Paying Agent, as applicable, to the applicable Governmental Authority, and (ii) treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made by Parent, Merger Sub, the Surviving Corporation, or the Paying Agent, as the case may be.

(g)Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent shall issue, or pay or cause to be paid, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and any cash in lieu of fractional shares and any dividends and distributions on such Certificate, in each case deliverable in respect thereof pursuant to this Agreement.

(h)Adjustments to Merger Consideration. In the event that the Company or Parent changes the number of shares of Company Common Stock, Parent Common Stock, shares of capital stock of the Company, shares of capital stock of Parent or securities convertible or exchangeable into or exercisable for shares of Company Common Stock, Parent Common Stock, shares of capital stock of the Company or shares of capital stock of Parent, as applicable, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, subdivision, exchange or readjustment of shares, or other similar transaction, then any number or amount contained herein which is based upon the price of Parent Common Stock, or the number of shares of Parent Common Stock or Company Common Stock, as the case may be, the Stock Consideration, the Cash Consideration, the Mixed Election Consideration and any other similarly dependent items shall be equitably adjusted to reflect such change;provided,however, that nothing in thisSection 2.02(h) shall be deemed to permit or authorize any party hereto to effect any such change that it is not otherwise authorized or permitted to undertake pursuant to this Agreement.

Section 2.03Treatment of Company Employee Stock Plans. The Company will adopt resolutions, provide all required notices and take such other actions as are necessary to effect the following:

(a)Effect on Company Stock Options. At the Effective Time, each Company Stock Option (or portion thereof) that is outstanding and unexercised as of immediately prior to the Effective Time (whether vested or unvested) shall without any action on the part of Parent, Merger Sub, the Company or the holder thereof, other than the Company delivering any notices required pursuant to the terms of the Company Employee Stock Plan, be cancelled and terminated and shall be converted into a right to receive an amount of Mixed Election Consideration that would be payable with respect to the Net Option Shares underlying such Company Stock Option no later than the Company’s next payroll date immediately following the Closing Date (the “Option Payment”). The payment of the Option Payment to the holder of a Company Stock Option shall be reduced by any applicable Tax withholding; provided that the applicable Taxes required to be withheld from the Option Payment (i) shall reduce first the cash portion of the Option Payment, with any remaining amount reducing the stock portion of the Option Payment and with the value of any reduction of the stock portion for purposes of such deduction to be determined based on the Equity Award Measurement Price, and (ii) shall be promptly remitted by the Company in cash to the applicable Governmental Authority. At or immediately following the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Company, for the benefit of the holders of Company Stock Options, the cash portion of the total Mixed Election Consideration payable with respect to the holders of the Company Stock Options in immediately available funds to be paid through the Company’s payroll systems. For the avoidance of doubt, each outstanding Company Stock Option with an exercise price per share that is in excess of the Cash Election Consideration shall be cancelled and extinguished at the Effective Time without any present or future right to receive any portion of the Merger Consideration or any other payment. For purposes hereof, “Net Option Shares” means, with respect to a Company Stock Option, the quotient of (i) the product of (A) the excess, if any, of the Cash Election Consideration over the exercise price per share of such Company Stock Optionmultiplied by(B) the number of Shares subject to such Company Stock Option,divided by(ii) the Cash Election Consideration.

A-9

(b)Effect on Company Restricted Stock Units.

(i) As of the Effective Time, each Company Restricted Stock Unit (or portion thereof) that is outstanding immediately prior to the Effective Time and subject to a performance-based vesting condition that relates solely to the value of the Company Common Stock shall, to the extent such Company Restricted Stock Unit vests in accordance with its terms in connection with the Merger (the “Participating RSUs”), be cancelled and extinguished and converted into the right to receive the Cash Election Consideration, the Stock Election Consideration or the Mixed Election Consideration in accordance with the Election made by the holder of such Participating RSUs in accordance with Section 2.02(b)(vi) (with payment to be effected pursuant toSection 2.01), subject to the applicable tax withholdings and subject to the provisions of Section 2.01(c) (as applicable, the “Cash Election RSUs”, the “Stock Election RSUs” or the “Mixed Election RSUs”). Any then-outstanding Company Restricted Stock Unit that is subject to a performance-based vesting condition that relates solely to the value of the Company Common Stock and is not vested after giving effect to the foregoing vesting determination will be cancelled and extinguished at the Effective Time without any present or future right to receive any portion of the Merger Consideration or any other payment.

(ii) At the Effective Time, each Company Restricted Stock Unit (or portion thereof) that is outstanding and unvested immediately prior to the Effective Time (and does not vest as a result of the consummation of the transactions contemplated hereby) and is either (x) subject to time-based vesting requirements only or (y) subject to a performance-based vesting condition other than the value of the Company Common Stock (including any other long-term incentive award subject to such performance-based vesting, whether denominated in dollars or shares) shall, by virtue of the Merger, be assumed by Parent (each, an “Assumed RSU”). Each such Assumed RSU shall be subject to substantially the same terms and conditions as applied to the related Company Restricted Stock Unit immediately prior to the Effective Time, including the vesting schedule (and the applicable performance-vesting conditions in the case of a grant contemplated by clause (y) of the preceding sentence) and any provisions for accelerated vesting applicable thereto, except that the number of shares of Parent Common Stock subject to each Assumed RSU shall be equal to the product of (i) the number of shares of Company Common Stock underlying such unvested Company Restricted Stock Unit award as of immediately prior to the Effective Time multiplied by (ii) Equity Award Exchange Ratio (with the resulting number, rounded down to the nearest whole share). As soon as practicable after the Effective Time, Parent shall deliver to each holder of a Company Restricted Stock Unit that is assumed by Parent pursuant to thisSection 2.03(b)(ii) appropriate notices setting forth the number of shares of Parent Common Stock subject to each Assumed RSU then held by such holder.

(c)Effect on ESPP. As soon as practicable following the date of this Agreement, the Company shall take such action as may be necessary to: (i) cause any offering period (or similar period during which shares may be purchased) underway as of the date hereof under the Company ESPP to be the final offering period under the Company ESPP, such that no new offering period will commence under the Company ESPP after the date hereof, and the current offering period underway shall be terminated no later than the Business Day immediately preceding the anticipated Closing Date (the “Final Exercise Date”), (ii) make any pro-rata adjustments that may be necessary to reflect the shortened offering period (or similar period), but otherwise treat such shortened offering period (or similar period) as a fully effective and completed offering period for all purposes under the Company ESPP, (iii) cause each participant’s outstanding purchase right under the Company ESPP (the “Company ESPP Rights”) to be exercised as of the Final Exercise Date, (iv) provide that no new participants enroll in the Company ESPP after the date hereof and that no current participant in the Company ESPP can increase his or her payroll deductions from those in effect on the date hereof, and (v) terminate the Company ESPP as of the Effective Time. On the Final Exercise Date, the funds credited as of such date under the Company ESPP within the associated accumulated payroll withholding account for each participant under the Company ESPP shall be used to purchase shares of Company Common Stock in accordance with the terms of the Company ESPP, and each share purchased thereunder immediately prior to the Effective Time shall be cancelled at the Effective Time and converted into the right to receive the Merger Consideration in accordance withSection 2.01(b). Any accumulated contributions of each participant under the Company ESPP as of immediately

A-10

prior to the Effective Time shall, to the extent not used to purchase shares in accordance with the terms and conditions of the Company ESPP (as amended pursuant to thisSection 2.03(c)), be refunded to such participant as promptly as practicable following the Effective Time (without interest). No further Company ESPP Rights shall be granted or exercised under the Company ESPP after the Final Exercise Date. The Company shall provide timely notice to participants of the setting of the Final Exercise Date and termination of the Company ESPP in accordance with the Company ESPP. Each participant in the Company ESPP who purchases shares thereunder on the Final Exercise Date (the “Participating ESPP Holders”) shall have the right to elect to receive their Merger Consideration in the form of the Cash Election Consideration, the Stock Election Consideration or the Mixed Election Consideration in accordance with the Election made by such participant in accordance withSection 2.02(b)(vi), subject to the provisions ofSection 2.01(c) (as applicable, the “Cash Election ESPPs”, the “Stock Election ESPPs” or the “Mixed Election ESPPs”).

(d)Form S-8. As soon as practicable after the Effective Time (but in no event later than 15 Business Days following the Effective Time), Parent shall cause to be filed with the SEC a registration statement on Form S-8 (or any successor form), if available for use by Parent, relating to the shares of Parent Common Stock issuable with respect to the Assumed RSUs eligible for registration on Form S-8 and shall use all reasonable efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses contained therein) for so long as the Assumed RSUs remain outstanding.

A-47

The Company shall (I) promptly (and in no event later than forty-eight (48) hours after receipt) notify Parent in writing of the initial receipt of any Company Takeover Proposal after the date of this Agreement but prior to the earlier of the receipt of the Company Stockholder Approval and the termination of this Agreement in accordance withArticle VII, which notice shall include the identity of the person making such Company Takeover Proposal, the material terms thereof (including the price and type of consideration offered by the person making such Company Takeover Proposal) and a copy of any written proposal or definitive agreement relating to the Company Takeover Proposal received by the Company or any of its subsidiaries or any of its or their respective Representatives in connection therewith (the “Proposal Information”), and (II) keep Parent reasonably informed of the status and materials terms (including any changes to the price and type of consideration offered) of any such Company Takeover Proposal and, promptly (but in no event later than forty-eight (48) hours) after receipt of any written material amendment or written proposed amendment of any such Company Takeover Proposal, the Company shall give Parent a copy thereof.

(e) Notwithstanding anything in this Agreement to the contrary, the Company Board may, prior to the receipt of the Company Stockholder Approval, effect a Company Change of Recommendation or terminate this Agreement pursuant toSection 7.01(h) to enter into a definitive agreement with respect to a Company Takeover Proposal if (and only if): (A) a written Company Takeover Proposal is made to or received by the Company after the date of this Agreement and has not been withdrawn at the time of such determination, (B) such Company Takeover Proposal did not result from a breach ofSection 4.03(a), (C) the Company Board determines in good faith after consultation with its financial advisor and outside legal counsel that (1) such Company Takeover Proposal constitutes a Company Superior Proposal and (2) failure to take such action would reasonably be likely to constitute a breach of the Company Board’s fiduciary duties under applicable law, (D) prior to taking such action, the Company provides Parent three (3) Business Days’ (the “Recommendation Change Notice Period”) prior written notice that the Company Board intends to take such action (a “Recommendation Change Notice”), which notice shall include the most current Proposal Information (it being understood that (x) such Recommendation Change Notice and any amendment or update to such notice and the determination to so deliver such notice shall not constitute a Company Change of Recommendation for purposes of this Agreement and (y) any material revision or amendment to the material terms of such Company Superior Proposal (including any change to the pricing or type of consideration thereof) shall require a new Recommendation Change Notice, except that the Recommendation Change Notice Period shall be reduced to two (2) Business Days after the initial Recommendation Change Notice Period), (E) during the Recommendation Change Notice Period, the Company shall have discussed and negotiated in good faith with Parent and its Representatives, if requested by Parent, any adjustments or modifications to the terms of this Agreement proposed by Parent or with respect to a new proposal from Parent, and (F) at the end of the Recommendation Change Notice Period (and any subsequent Recommendation Change Notice Periods required pursuant hereto), the Company Board determines in good faith, after consultation with its financial advisor and outside legal counsel, that (1) such Company Takeover Proposal would continue to constitute a Company Superior Proposal (assuming the adjustments or modifications to the terms of this Agreement proposed in writing by Parent in a manner capable of being accepted by the Company as a binding contract were to be given effect) and (2) that the failure to take such action would reasonably be likely to constitute a breach of its fiduciary duties under applicable law.

(i) For purposes of this Agreement, “Company Superior Proposal” means any written Company Takeover Proposal (that is not withdrawn) that the Company Board determines in good faith, after consultation with its financial advisor and outside legal counsel, (x) is reasonably likely to be consummated in accordance with its terms, and (y) if consummated, would be more favorable to the Company’s stockholders, in their capacities as such, than the Merger from a financial point of view, taking into account all relevant financial, legal, regulatory, financing, certainty and timing of consummation aspects of such Company Takeover Proposal (including any changes to the financial or other terms of this Agreement or the Merger proposed in writing by Parent in a manner capable of being accepted by the Company as a binding contract as a binding contract), except that all of the references to “25%” and “75%” in the definition of “Company Takeover Proposal,” shall each be deemed to be a reference to “50%” and “50%”, respectively, for purposes of this definition of “Company Superior Proposal”.

For purposes of this Agreement, a “Company Intervening Event” means a Change that affects or would be reasonably likely to affect (x) the business, financial condition or continuing results of operations of the Company and its subsidiaries, taken as a whole, or (y) the benefits of the Merger to the Company or the stockholders of the Company, in either case that (1) is material, individually or in the aggregate with any other such Changes, to the Company and its subsidiaries, taken as a whole, or the stockholders of the Company, (2) is not known and is not reasonably foreseeable (or the material consequences of which are not known and not reasonably foreseeable), in each case, as of the date hereof and (3) does not relate to or involve any Company Takeover Proposal; provided that (I) in no event shall any action taken by any party hereto pursuant to the affirmative covenants set forth inSection 5.03, or the consequences of any such action, constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Company Intervening Event, and (II) in no event shall any Change that would fall within any of the exceptions to the definition of “Parent Material Adverse Effect” constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Company Intervening Event.

Parent shall not agree to any amendments or modifications to, or grant any waivers of, any condition or other provision under the Debt Financing Commitment without the prior written consent of the Company to the extent such amendments, modifications or waivers would (A) reduce the aggregate amount of cash proceeds available from the Debt Financing such that such cash proceeds, together with the financial resources of Parent and its affiliates including cash on hand and the proceeds of loans under existing credit facilities of Parent or its subsidiaries on the Closing Date, in the aggregate, are insufficient to fund the amounts required to be paid by Parent or Merger Sub under this Agreement and the other transactions contemplated by this Agreement, (B) impose new or additional conditions or amend, modify or expand existing conditions precedent as compared to those in the Debt Financing Commitment and Fee Letter as in effect on the date hereof in each case in a manner that would materially delay or prevent the funding of the Debt Financing, (C) adversely affect the ability of Parent to enforce its rights against other parties to the Debt Financing Commitment, Fee Letter or the definitive documentation governing the Debt Financing as so amended, replaced, supplemented or otherwise modified, relative to the ability of Parent to enforce its rights against such other parties to the Debt Financing Commitment and Fee Letter as in effect on the date hereof, (D) otherwise prevent, or materially impede, impair or delay the Closing, or (E) affect Parent’s ability to consummate the transactions contemplated by this Agreement on the terms contemplated by this Agreement (the terms described in (A)-(E), collectively, the “Prohibited Terms”);provided, that for the avoidance of doubt, nothing herein shall prohibit other amendments, including those to replace or amend the Debt Financing Commitment to add or replace lenders, lead arrangers, bookrunners, syndication agents or similar entities that have not executed the Debt Financing Commitment as of the date hereof. Parent shall promptly provide the Company with copies of all executed amendments, modifications or replacements of the Debt

A-51

Financing Commitment or definitive agreements related to the Debt Financing. Without limiting the generality of the foregoing, Parent or Merger Sub shall give the Company prompt notice of the receipt of any written notice or other written communication from any Debt Financing Party with respect to any (x) actual or alleged in writing material breach or default, termination or repudiation by any party to any of the Debt Financing Commitment or any definitive document related to the Debt Financing or any provisions of the Debt Financing Commitment or any definitive document related to the Debt Financing, or (y) of any termination, expiration, or waiver, amendment or other modification of the Debt Financing Commitment. If any portion of the Debt Financing contemplated by the Debt Financing Commitment become unavailable on the terms and conditions contemplated thereby (including flex provisions, if applicable), and such portion is required to fund any portion of the aggregate Cash Consideration and any fees, expenses and other amounts contemplated to be paid by Parent, Merger Sub, the Surviving Corporation or the pursuant to this Agreement (taking into account the cash on hand and other proceeds available to Parent and its subsidiaries), Parent and Merger Sub shall use their reasonable best efforts to arrange and obtain in replacement thereof alternative financing from alternative sources in an amount sufficient to consummate the transactions contemplated by this Agreement on terms that do not contain any Prohibited Terms, it being understood that if Parent proceeds with any alternative financing, Parent will be subject to the same obligations with respect to such alternative financing as set forth in this Agreement with respect to the Debt Financing; provided, however that if the Company is then currently seeking specific performance or injunctive relief pursuant toSection 8.11 to cause the consummation of the Merger, the restriction on including Prohibited Terms in such alternative financing at such time shall not apply. Parent will deliver to the Company true, correct and complete copies of all agreements pursuant to which any source has committed to provide such alternative financing. Any reference in this Agreement to (1) the “Debt Financing” shall include any such alternative financing, (2) the “Debt Financing Commitment” shall include the commitment letter (including any related exhibits, schedules, annexes, supplements and other related documents) and the corresponding fee letter with respect to any such alternative financing, and (3) the “Debt Financing Parties” shall include the financing institutions contemplated to provide any such alternative financing. The Company acknowledges that the covenants and obligations contained in thisSection 4.05 and the Debt Financing Commitment are the sole and exclusive covenants and obligations of Parent and its subsidiaries and each of their respective Representatives in connection with obtaining the Debt Financing;provided,however, that Parent and Merger Sub expressly acknowledge and agree that Parent’s and Merger Sub’s obligations to hold the Closing and consummate the Merger (including pursuant toSection 1.02 andSection 1.03) shall not in any way be conditioned upon whether the Debt Financing is available or has been obtained and failure to obtain all or any portion of the Debt Financing (or any alternative financing) will not in and of itself relieve or alter Parent’s obligations to consummate the transactions contemplated by this Agreement upon the terms set forth in the Transaction Documents.

(e) Parent shall (1), in consultation with the Company, take all necessary actions to establish a record date for, and to duly call, give notice of, and convene the Parent Special Meeting in accordance with applicable law and organizational documents of Parent for the purpose of obtaining the Parent Stockholder Approval and (2) include the Parent Board Recommendation in the Joint Proxy Statement, maintain such recommendation and solicit and use its reasonable best efforts to obtain the Parent Stockholder Approval.

(i) Notwithstanding anything in this Agreement to the contrary, the Parent Board may, prior to the receipt of the Parent Stockholder Approval, withdraw, amend or modify, or publicly propose to withdraw, amend or modify, the Parent Board Recommendation in a manner adverse to the Company in connection with an Parent Intervening Event (a “Parent Change of Recommendation”) if (and only if): (A) an Parent Intervening Event has occurred and is continuing, (B) the Parent Board determines in good faith after consultation with its financial advisor and outside legal counsel that failure to take such action would reasonably be likely to constitute a breach of the Parent Board’s fiduciary duties under applicable law, (C) prior to taking such action, Parent provides the Company prior written notice equal to the Recommendation Change Notice Period that the Parent Board intends to take such action (a “Parent Intervening Event Recommendation Change Notice”), which notice shall include a reasonable summary of the Parent Intervening Event (it being understood that (x) such Parent Intervening Event Recommendation Change Notice and any amendment or update to such notice and the determination to so deliver such notice shall not constitute a Parent Change of Recommendation for purposes of this Agreement and (y) any material change to the status of the Parent Intervening Event shall require a new Parent Intervening Event Recommendation Change Notice, except that the Recommendation Change Notice Period shall be reduced to two (2) Business Days after the initial Recommendation Change Notice Period), (D) during the Recommendation Change Notice Period, Parent shall have discussed and negotiated in good faith with the

A-56

Company and its Representatives, if requested by the Company, any adjustments or modifications to the terms of this Agreement or with respect to a new proposal from the Company, and (E) at the end of the Recommendation Change Notice Period (and any subsequent Recommendation Change Notice Periods required pursuant hereto), the Company shall not have made a written offer or proposal capable of being accepted by Parent that the Parent Board determines in good faith, after consultation with its financial advisor and outside legal counsel, would obviate the need for the Parent Board to effect such Parent Change of Recommendation.

(ii) Nothing contained in this Agreement shall prohibit Parent or the Parent Board, directly or indirectly, including through its Representatives, from (A) disclosing to the Parent’s stockholders a position contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act or (B) making any disclosure to its stockholders if the Parent Board has determined, after consultation with outside legal counsel, that the failure to do so would be inconsistent with applicable law; provided, however, that in the case of the foregoing clauses (A) or (B) of thisSection 5.01(e)(ii), any such action taken or statement made that contains a Parent Change of Recommendation shall only be made in compliance withSection 5.01(e)(i).

(iii) For purposes of this Agreement, a “Parent Intervening Event” means a Change that affects or would be reasonably likely to affect (x) the business, financial condition or continuing results of operations of Parent and its subsidiaries, taken as a whole, or (y) the benefits of the Merger to Parent or the shareholders of Parent, in either case that (A) is material, individually or in the aggregate with any other such Changes, to Parent and its subsidiaries, taken as a whole, or the shareholders of Parent, (B) is not known and is not reasonably foreseeable (or the material consequences of which are not known and not reasonably foreseeable) as of the date hereof and (C) does not relate to or involve any Parent Takeover Proposal; provided that (I) in no event shall any action taken by any party hereto pursuant to the affirmative covenants set forth inSection 5.03, or the consequences of any such action, constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Parent Intervening Event, (II) in no event shall any Change that would fall within any of the exceptions to the definition of “Company Material Adverse Effect” constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Parent Intervening Event and (III) in no event shall any item set forth inSection 5.01(e)(iii) of the Company Disclosure Letter constitute, be deemed to contribute to or otherwise be taken into account in determining whether there has been a Parent Intervening Event.

(iv) For purposes of this Agreement, “Parent Takeover Proposal” means, other than the transactions contemplated by this Agreement, any bona fideproposal, indication of interest or offer from any person or “group” (as defined in or under Section 13(d) of the Exchange Act) relating to (A) any direct or indirect acquisition or purchase of a business that constitutes or generates 25% or more of the net revenues or assets of the Parent and its subsidiaries, taken as a whole or any assets representing 25% or more of the consolidated assets of the Parent and its subsidiaries, taken as a whole (in any case contemplated by this clause (A), measured by the lesser of book or fair market value thereof as of the last day of Parent’s last fiscal year as of such time), (B) any direct or indirect acquisition or purchase of 25% or more of any outstanding class of voting or equity securities of Parent or of any subsidiary of Parent, (C) any tender offer or exchange offer that if consummated would result in any person beneficially owning 25% or more of any outstanding class of voting or equity securities of Parent or any of its subsidiaries, or (D) any merger, consolidation, business combination, or other similar extraordinary transaction involving Parent or any of its subsidiaries pursuant to which the holders of the Parent Common Stock immediately preceding such transaction hold, directly or indirectly, less than 75% of the outstanding voting or equity interests in the surviving or resulting entity of such transaction. For the avoidance of doubt, the inclusion of references to “Parent Takeover Proposal” in this Agreement does not impose any obligation of Parent with respect to a Parent Takeover Proposal as between Parent and the Company.

(f) The Company and Parent shall not, without the prior written consent of the other party, adjourn, postpone or otherwise delay the Company Special Meeting or the Parent Special Meeting, respectively;provided, that the Company and Parent may, with the consultation of the other party, adjourn or postpone the Company

A-57

If such insurance coverage cannot be maintained for such cost, Parent shall maintain the most advantageous policies of directors’ and officers’ insurance otherwise obtainable for such cost. Prior to the Effective Time, the Company may purchase a six-year “tail” prepaid policy on terms and conditions no less favorable to the Company Indemnified Parties than the existing directors’ and officers’ liability (and fiduciary) insurance maintained by the Company, covering without limitation the transactions contemplated hereby;provided, that the aggregate cost thereof shall not exceed 250% of the annual cost of the directors’ and officers’ liability (and fiduciary) insurance maintained by the Company as of the date hereof. If such “tail” prepaid policy has been obtained by the Company prior to the Effective Time, it shall satisfy the obligations set forth in the first two sentences of this paragraph (b).

The Company, Parent and Merger Sub each acknowledge that the agreements contained inSection 7.03 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, none of Parent, Merger Sub, or the Company would enter into this Agreement, and that any amounts payable pursuant toSection 7.03 do not constitute a penalty but constitute payment of liquidated damages and that the liquidated damages amount is reasonable in light of the substantial but indeterminate harm anticipated to be caused by the other party’s breach or default under this Agreement, the difficulty of proof and calculation of loss and damages, the inconvenience and non-feasibility of otherwise obtaining an adequate remedy, the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Merger and the other transactions contemplated hereby and the value of the transactions to be consummated hereunder. If the Company fails to promptly pay the Company Termination Fee when required to be paid pursuant toSection 7.03 and, in order to obtain payment of the Company Termination Fee, Parent or Merger Sub commences a suit that results in a final non-appealable order against the Company for the payment of the Company Termination Fee to Parent, the Company shall pay Parent its reasonable, documented and out-of-pocket costs and expense (including reasonable, documented and out-of-pocket attorneys’ fees) in connection with such suit, together with interest, commencing from the date that the Company Termination Fee was due and payable, on the amount of the Company Termination Fee at the prime rate published in the Money Rates section of The Wall Street Journal in effect on the date such payment of the Company Termination Fee was required to be made.

(b) If the Company or its designee shall receive full payment of the Parent Termination Fee pursuant toSection 7.04, then the receipt of the Parent Termination Fee by Parent or its designee shall be the sole and exclusive remedy of the Company and their respective affiliates and representatives for any and all liability, loss and damage relating to or arising out of this Agreement, the Merger and the other agreements, certificates, instruments and transactions contemplated hereby. In no event shall the Company be required to pay the Company Termination Fee more than once in any circumstance. The Company, Parent and Merger Sub each acknowledge that the agreements contained inSection 7.04 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, none of Parent, Merger Sub, or the Company would enter into this Agreement, and that any amounts payable pursuant toSection 7.04 do not constitute a penalty but constitute payment of liquidated damages and that the liquidated damages amount is reasonable in light of the substantial but indeterminate harm anticipated to be caused by the other party’s breach or default under this Agreement, the difficulty of proof and calculation of loss and damages, the inconvenience and non-feasibility of otherwise obtaining an adequate remedy, the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Merger and the other transactions contemplated hereby and the value of the transactions to be consummated hereunder. If Parent fails to promptly pay the Parent Termination Fee when required to be paid pursuant toSection 7.04 and, in order to obtain payment of the Parent Termination Fee, the Company commences a suit that results in a final non-appealable order against Parent for the payment of the Parent Termination Fee to the Company, Parent shall pay the Company its reasonable, documented and out-of-pocket costs and expense (including reasonable, documented and out-of-pocket attorneys’ fees) in connection with such suit, together with interest, commencing from the date that the Parent Termination Fee was due and payable, on the amount of the Parent Termination Fee at the prime rate published in the Money Rates section of The Wall Street Journal in effect on the date such payment of the Parent Termination Fee was required to be made.

II-VI Incorporated

375 Saxonburg Boulevard

Saxonburg, PA 16056

Members of the Board of Directors:

We understand thatII-VI Incorporated, a Pennsylvania corporation(“II-VI”), proposes to enter into an Agreement and Plan of Merger (the “Agreement”), amongII-VI, Mutation Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary ofII-VI (“Merger Sub”), and Finisar Corporation, a Delaware corporation (“Finisar”), pursuant to which, among other things, Merger Sub will merge with and into Finisar (the “Merger”), and each outstanding share of the common stock, par value $0.001 per share, of Finisar (“Finisar Common Stock”) will be converted into the right to receive, at the option of the holder thereof and subject to certain limitations and proration procedures set forth in the Agreement (as to which we express no opinion):(i) $26.00 in cash; (ii) 0.5546 shares of the common stock, no par value, ofII-VI(“II-VI Common Stock”); or (iii) a combination of (A) 0.2218 shares ofII-VI Common Stock and (B) $15.60 in cash (collectively, the “Consideration”). The terms and conditions of the Merger are more fully set forth in the Agreement.

You have requested our opinion as to the fairness, from a financial point of view, toII-VIof theConsideration to be paid byII-VI in the Merger.

In connection with this opinion, we have, among other things:

(1) reviewed certain publicly available business and financial information relating to Finisar andII-VI;

(2) reviewed certain internal financial and operating information with respect to the business, operations and prospects of Finisar furnished to or discussed with us by the management of Finisar, including certain financial forecasts relating to Finisar prepared by the management of Finisar (such forecasts, the “Finisar Forecasts”);

(3) reviewed certain financial forecasts relating to Finisar prepared by the management ofII-VI (the“II-VI-Finisar Forecasts”) and discussed with the management ofII-VI its assessments as to the relative likelihood of achieving the future financial results reflected in the Finisar Forecasts and theII-VI-Finisar Forecasts;

(4) reviewed certain internal financial and operating information with respect to the business, operations and prospects ofII-VI furnished to or discussed with us by the management ofII-VI, including certain financial forecasts relating toII-VI prepared by the management ofII-VI(such forecasts, the“II-VI Forecasts”);

(5) reviewed certain estimates as to the amount and timing of cost savings (collectively, the “Cost Savings”) anticipated by the management ofII-VI to result from the Merger;

(6) discussed the past and current business, operations, financial condition and prospects of Finisar with members of the senior managements of Finisar andII-VI, and discussed the past and current business, operations, financial condition and prospects ofII-VI with members of the senior management ofII-VI;

B-1

(7) discussed with the management ofII-VI its assessments as to (a) Finisar’s existing and future relationships, agreements and arrangements with, andII-VI’s ability to retain, key customers, suppliers, and employees of Finisar and (b) the products, product candidates and technology of Finisar, including the validity of, risks associated with,and the integration byII-VI of, such products, product candidates and technology;

(8) reviewed the potential pro forma financial impact of the Merger on the future financial performance ofII-VI, including the potential effect onII-VI’s estimated earnings per share;

(9) reviewed the trading histories for Finisar Common Stock andII-VI Common Stock and a comparison of such trading histories with each other and with the trading histories of other companies we deemed relevant;

(10) compared certain financial and stock market information of Finisar andII-VI with similar information of other companies we deemed relevant;

(11) compared certain financial terms of the Merger to financial terms, to the extent publicly available, of other transactions we deemed relevant;

(12) reviewed the relative financial contributions of Finisar andII-VI to the future financial performance of the combined company on a pro forma basis;

(13) reviewed a draft, dated November 8, 2018, of the Agreement, and share capitalization information furnished by Finisar andII-VI (collectively, the “Draft Agreement”); and

(14) performed such other analyses and studies and considered such other information and factors as we deemed appropriate.

In arriving at our opinion, we have assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with us and have relied upon the assurances of the managements ofII-VIand Finisar that they are not aware of any facts or circumstances that would make such information or data inaccurate or misleading in any material respect. With respect to the Finisar Forecasts, we have been advised by Finisar, and have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Finisar as to the future financial performance of Finisar. With respect to theII-VI-Finisar Forecasts, theII-VI Forecasts and the Cost Savings, we have assumed, at the direction ofII-VI, that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management ofII-VI as to the future financial performance of Finisar andII-VI and the other matters covered thereby and, based on the assessments of the management ofII-VI as to the relative likelihood of achieving the future financial results reflected in the Finisar Forecasts and theII-VI-Finisar Forecasts, we have relied, at the direction ofII-VI, on theII-VI-Finisar Forecasts for purposes of our opinion. We have relied, at the direction ofII-VI, on the assessments of the management ofII-VI as toII-VI’s ability to achieve the Cost Savings and have been advised byII-VI, and have assumed, that the Cost Savings will be realized in the amounts and at the times projected.

We have not made or been provided with any independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of FinisarorII-VI, nor have we made any physical inspection of the properties or assets of FinisarorII-VI. We have not evaluated the solvency or fair value of Finisar orII-VI under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. We have assumed, at the direction ofII-VI, that the Merger will be consummated in accordance with its terms, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessarygovernmental, regulatory and other approvals, consents, releases and waivers for the Merger, no delay, limitation, restriction or condition, including any divestiture requirements or amendments or modifications, will be imposed that would have an adverse effect on Finisar,II-VI or the contemplated benefits of the Merger. We also have assumed, at the direction ofII-VI, that the final executed Agreement will not differ in any material respect from the Draft Agreement reviewed by us.

B-2

We express no view or opinion as to any terms or other aspects or implications of the Merger (other than the Consideration to the extent expressly specified herein), including, without limitation, the form or structure of the Merger, any related transactions or any other agreement, arrangement or understanding entered into in connection with or related to the Merger or otherwise. Our opinion is limited to the fairness, from a financial point of view, toII-VI of the Consideration to be paid in the Merger and no opinion or view is expressed with respect to any consideration received in connection with the Merger by the holders of any class of securities, creditors or other constituencies of any party. In addition, no opinion or view is expressed with respect to the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation to any of the officers, directors or employees of any party to the Merger, or class of such persons, relative to the Consideration or otherwise. Furthermore, no opinion or view is expressed as to the relative merits of the Merger in comparison to other strategies or transactions that might be available toII-VI or in whichII-VI might engage or as to the underlying business decision ofII-VI to proceed with or effect the Merger. We are not expressing any view or opinion as to what the value ofII-VICommon Stock actually will be when issued or the prices at whichII-VICommon Stock or FinisarCommon Stock will trade at any time, including following announcement or consummation of the Merger. We are also not expressing any view or opinion with respect to, and we have relied, at the direction ofII-VI, upon the assessments of representatives ofII-VI regarding, legal, regulatory, accounting, tax or similar matters relating to Finisar,II-VI or the Merger (including the contemplated benefits of the Merger), as to which matters we understand thatII-VI obtained such advice as it deemed necessary from qualified professionals. In addition, we express no opinion or recommendation as to how any stockholder should vote or act in connection with the Merger or any other matter.

We have acted as financial advisor toII-VI in connection with the Merger and will receive a fee for our services, a portion of which is payable upon delivery of this opinion and the principal portion of which is contingent upon consummation of the Merger. We and certain of our affiliates also are participating in the financing for the Merger, for which services we and our affiliates will receive significant compensation contingent on the consummation of the Merger, including acting as left lead arranger and administrative agent in connection with the $2,425 million underwritten credit facility comprising a portion of such financing. In addition,II-VI has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement.

We and our affiliates comprise a full service securities firm and commercial bank engaged in securities, commodities and derivatives trading, foreign exchange and other brokerage activities, and principal investing as well as providing investment, corporate and private banking, asset and investment management, financing and financial advisory services and other commercial services and products to a wide range of companies, governments and individuals. In the ordinary course of our businesses, we and our affiliates may invest on a principal basis or on behalf of customers or manage funds that invest, make or hold long or short positions, finance positions or trade or otherwise effect transactions in equity, debt or other securities or financial instruments (including derivatives, bank loans or other obligations) ofII-VI, Finisar and certain of their respective affiliates.

We and our affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services toII-VI and have received or in the future may receive compensation for the rendering of these services, including (i) having acted or acting as aco-lead arranger for, and as a lender under,II-VI’s revolving credit facility, (ii) having acted as a book running manager in a convertible bond offering forII-VI, (iii) having provided or providing foreign exchange trading services toII-VI, and (iv) having provided or providing certain treasury management services and products toII-VI.

In addition, we and our affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services to Finisar and have received or in the future may receive compensation for the rendering of these services, including having acted as a book running manager in a convertible bond offering for Finisar and having provided or providing foreign exchange and fixed income trading services to Finisar.

B-3

It is understood that this letter is for the benefit and use of the Board of Directors ofII-VI (in its capacity as such) in connection with and for purposes of its evaluation of the Merger.

Our opinion is necessarily based on financial, economic, monetary, market and other conditions and circumstances as in effect on, and the information made available to us as of, the date hereof. As you are aware, the credit, financial and stock markets have been experiencing unusual volatility and we express no opinion or view as to any potential effects of such volatility onII-VI, Finisar or the Merger. It should be understood that subsequent developments may affect this opinion, and we do not have any obligation to update, revise, or reaffirm this opinion. The issuance of this opinion was approved by a fairness opinion review committee of Merrill Lynch, Pierce, Fenner & Smith Incorporated.

Based upon and subject to the foregoing, including the various assumptions and limitations set forth herein, we are of the opinion on the date hereof that the Consideration to be paid in the Merger byII-VI is fair, from a financial point of view, toII-VI.

Very truly yours,

Members of the Board of Directors:

We understand that Finisar Corporation, a Delaware corporation (the “Company”), intends to enter into a transaction (the “Proposed Transaction”) withII-VI Incorporated, a Pennsylvania corporation(“II-VI”), pursuant to which, among other things, Mutation Merger Sub, Inc., a Delaware corporation and newly formed, wholly-owned subsidiary ofII-VI (“Merger Sub”), will merge with and into the Company with the Company surviving the merger and all of the authorized shares of the common stock of the Company (other than shares of the Company (i) owned by the Company as treasury stock, (ii) owned byII-VI, (iii) owned by Merger Sub or any other direct or indirect wholly-owned subsidiary ofII-VI, and (iv) owned by any direct or indirect wholly-owned subsidiary of the Company), par value $0.001 (the “Company Common Stock”), will be converted at the election of each holder thereof into the right to receive (x) $26.00 in cash (the “Cash Consideration”), (y) 0.5546 shares of the common stock ofII-VI, no par value (the“II-VI Common Stock”) (the “Stock Consideration”) or (z) $15.60 in cash and 0.2218 shares ofII-VI Common Stock (the “Mixed Consideration” and, together with the Cash Consideration and the Stock Consideration to be paid for all of the shares of Company Common Stock pursuant to the Proposed Transaction, the “Merger Consideration”), subject to proration as more fully set forth in the Agreement (as defined below), as to which proration we express no opinion. The terms and conditions of the Proposed Transaction are set forth in more detail in the Agreement and Plan of Merger (the “Agreement”), dated as of November 8, 2018, by and amongII-VI, Merger Sub and the Company. The summary of the Proposed Transaction set forth above is qualified in its entirety by the terms of the Agreement.

We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company’s stockholders of the Merger Consideration to be offered to such stockholders in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company’s underlying business decision to proceed with or effect the Proposed Transaction or the likelihood of consummation of the Proposed Transaction. In addition, we express no opinion on, and our opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the Proposed Transaction, or any class of such persons, relative to the Merger Consideration to be offered to the stockholders of the Company in the Proposed Transaction. Our opinion does not address the relative merits of the Proposed Transaction as compared to any other transaction or business strategy in which the Company might engage.

In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the Proposed Transaction; (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including its Annual Report on Form10-K for the fiscal year ended April 29, 2018 and its Quarterly Report on Form10-Q for the fiscal quarter ended July 29, 2018; (3) publicly available information concerningII-VI that we believe to be relevant to our analysis, including its Annual Report on Form10-K for the

C-1

fiscal year ended June 30, 2018 and its Quarterly Report on Form10-Q for the fiscal quarter ended September 30, 2018; (4) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including financial projections of the Company prepared by the management of the Company (the “Company Projections”); (5) financial and operating information with respect to the business, operations and prospects ofII-VI furnished to us byII-VI and the Company, including financial projections ofII-VI prepared by the management ofII-VI and reviewed and approved for use by the management of the Company (the “Company’sII-VI Projections”); (6) published estimates of independent research analysts with respect to the future financial performance of the Company andII-VI; (7) a trading history of the shares of Company Common Stock from November 8, 2013 to November 8, 2018; (8) a trading history of the shares ofII-VI Common Stock from November 8, 2013 to November 8, 2018; (9) a comparison of the historical financial results and present financial condition of the Company andII-VI with those of other companies that we deemed relevant; (10) the pro forma impact of the Proposed Transaction on the future financial performance of the combined company, including cost savings, operating synergies, and other strategic benefits, expected by the management of the Company to result from a combination of the businesses (the “Expected Synergies”); and (11) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other transactions that we deemed relevant. In addition, we have had discussions with the management of the Company and the management ofII-VI concerningII-VI’s business, operations, assets, liabilities, financial condition and prospects and have had discussions with the management of the Company concerning the Company’s business, operations, assets, liabilities, financial condition and prospects, and have undertaken such other studies, analyses and investigations as we deemed appropriate.

In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without any independent verification of such information (and have not assumed responsibility or liability for any independent verification of such information) and have further relied upon the assurances of the management of the Company and the management ofII-VI that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Company Projections, upon the advice of the Company, we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company. With respect to the Company’sII-VI Projections, upon the advice of the Company, we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance ofII-VI. Furthermore, upon the advice of the Company, we have assumed that the amounts and timing of the Expected Synergies are reasonable and that the Expected Synergies will be realized in accordance with such estimates. We assume no responsibility for and we express no view as to any such projections or estimates or the assumptions on which they are based. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company orII-VI and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company orII-VI. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. We assume no responsibility for updating or revising our opinion based on events or circumstances that may occur after the date of this letter. We express no opinion as to the prices at which shares of Company Common Stock or shares ofII-VI Common Stock would trade following the announcement of the Proposed Transaction or as to the prices at which shares ofII-VI Common Stock would trade following the consummation of the Proposed Transaction. Our opinion should not be viewed as providing any assurance that the market value of the shares ofII-VI Common Stock to be held by the stockholders of the Company after the consummation of the Proposed Transaction will be in excess of the market value of the shares of Company Common Stock owned by such stockholders at any time prior to the announcement or consummation of the Proposed Transaction.

We have assumed the accuracy of the representations and warranties contained in the Agreement and all agreements related thereto. We have also assumed, upon the advice of the Company, that all material governmental, regulatory and third party approvals, consents and releases for the Proposed Transaction will be obtained within the constraints contemplated by the Agreement and that the Proposed Transaction will be

C-2

consummated in accordance with the terms of the Agreement without waiver, modification or amendment of any material term, condition or agreement thereof. We do not express any opinion as to any tax or other consequences that might result from the Proposed Transaction, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that the Company has obtained such advice as it deemed necessary from qualified professionals.

Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the Merger Consideration to be offered to the stockholders of the Company in the Proposed Transaction is fair to such stockholders.

We have acted as financial advisor to the Company in connection with the Proposed Transaction and will receive fees for our services a portion of which is payable upon rendering this opinion and a substantial portion of which is contingent upon the consummation of the Proposed Transaction. In addition, the Company has agreed to reimburse our expenses and indemnify us for certain liabilities that may arise out of our engagement. We have performed various investment banking services for the Company andII-VI in the past, and expect to perform such services in the future, and have received, and expect to receive, customary fees for such services. However, in the past two years, we have not earned any investment banking fees from either the Company orII-VI.

Barclays Capital Inc., its subsidiaries and its affiliates engage in a wide range of businesses from investment and commercial banking, lending, asset management and other financial andnon-financial services. In the ordinary course of our business, we and our affiliates may actively trade and effect transactions in the equity, debt and/or other securities (and any derivatives thereof) and financial instruments (including loans and other obligations) of the Company andII-VI for our own account and for the accounts of our customers and, accordingly, may at any time hold long or short positions and investments in such securities and financial instruments.

This opinion, the issuance of which has been approved by our Fairness Opinion Committee, is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the Proposed Transaction. This opinion is not intended to be and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote or act with respect to the Proposed Transaction.

Very truly yours,

BARCLAYS CAPITAL INC.

Annex D

Section 262 of the DGCL

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title § 251(h) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that, except as expressly provided in § 363(b) of this title, no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation (or, in the case of a merger pursuant to § 251(h), as of immediately prior to the execution of the agreement of merger), were either: (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (b)(1) of this section, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a. and b. of this section; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a., b. and c. of this section.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 or § 267 of this title is not owned by the parent immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(4) In the event of an amendment to a corporation’s certificate of incorporation contemplated by § 363(a) of this title, appraisal rights shall be available as contemplated by § 363(b) of this title, and the

D-1

procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as practicable, with the word “amendment” substituted for the words “merger or consolidation,” and the word “corporation” substituted for the words “constituent corporation” and/or “surviving or resulting corporation.”

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d), (e), and (g) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice or, in the case of a merger approved pursuant to § 251(h) of this title, within the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of

D-2

the first notice or, in the case of a merger approved pursuant to § 251(h) of this title, later than the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation (or, in the case of a merger approved pursuant to § 251(h) of this title, the aggregate number of shares (other than any excluded stock (as defined in § 251(h)(6)d. of this title)) that were the subject of, and were not tendered into, and accepted for purchase or exchange in, the offer referred to in § 251(h)(2)), and, in either case, with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their

D-3

certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. If immediately before the merger or consolidation the shares of the class or series of stock of the constituent corporation as to which appraisal rights are available were listed on a national securities exchange, the Court shall dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal rights unless (1) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (2) the value of the consideration provided in the merger or consolidation for such total number of shares exceeds $1 million, or (3) the merger was approved pursuant to § 253 or § 267 of this title.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided in this subsection, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving corporation may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided herein only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Court, and (2) interest theretofore accrued, unless paid at that time. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such

D-4

stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

PART II: INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Pennsylvania statutory law regarding directors and officers insurance and indemnification is embodied in Chapter 17, Subchapter D (Sections 1741 through 1750) of the BCL.

Sections 1741 (relating to third-party actions) and 1742 (relating to derivative and corporate actions) of the BCL provide that a business corporation may indemnify any director, officer, employee or agent who is or was a representative of, or serving at the request of, the corporation (a “Representative”), so long as the Representative acted in good faith and with a reasonable belief that his or her actions were in the best interests, or not opposed to the best interests, of the corporation, and with respect to any criminal proceeding under Section 1741 of the BCL, the Representative must have had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under these sections does not exist in the case of actions against a director or officer by or in the right of the corporation if the person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for specified expenses.

Section 1743 of the BCL provides mandatory indemnification for a Representative if he or she succeeds on the merits or otherwise in the defense of any claim or action or proceeding, or in defense of any claim, issue or matter therein. The corporation must indemnify him or her to the extent of his or her actual and reasonable expenses (including attorney’s fees) incurred in connection with the claim or action.

Section 1745 of the BCL states that expenses (including attorneys’ fees) incurred in defending any third-party or derivative action or proceeding may be paid by a business corporation in advance of the final disposition of the action or proceeding upon receipt of an undertaking by or on behalf of the Representative to repay the amount if it is ultimately determined that such person is not entitled to be indemnified by the corporation as authorized by the BCL or otherwise. Except as otherwise provided in the corporation’s bylaws, advancement of expenses must be authorized by the board of directors of the corporation and shall not be authorized in connection with proceedings related to transactions with interested directors or officers, or interested shareholders (Sections 1728 and 2538 of the BCL).

Section 1746(a) states that the statutory rights of indemnification and advancement of expenses shall not be deemed exclusive of any other rights to which a person might be entitled under any bylaw, agreement, vote of shareholders or disinterested directors, or otherwise, both as to the action in his or her official capacity and as to the action or proceeding in another capacity while holding that office. However, Section 1746(b) forbids indemnification to be made in any case where the act or failure to act giving rise to the claim is determined by a court to be willful misconduct or recklessness. A corporation’s articles of incorporation may not provide for indemnification in the case of willful misconduct or recklessness.

The BCL, in Section 1747, also authorizes corporations to purchase and maintain insurance on behalf of a Representative or a person who is or was serving at the request of the corporation as a Representative of another domestic or foreign entity, whether or not the corporation would have the power to indemnify him or her, unless otherwise restricted in its bylaws. Such insurance is declared to be consistent with Pennsylvania’s public policy.

Section 1750 of the BCL provides that the indemnification and advancement of expenses provided by, or granted pursuant to Subchapter D of the BCL shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a Representative and shall inure to the benefit of the heirs and personal representatives of that person.

Section 6.02 of theII-VIBy-Laws provides that a director shall not be personally liable for monetary damages for any action taken or failed to be taken unless the director has breached or failed to perform the duties

II-1

of his or her office (relating to standard of care and justifiable reliance) and such breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. A director’s criminal or tax liability is not limited by the foregoing provision.

Section 6.03 of theII-VIBy-Laws requiresII-VI to indemnify any director or officer ofII-VI to the fullest extent not prohibited by law in connection with any actual or threatened action, suit or proceeding, civil, criminal, administrative, investigative or other (whether brought by or in the right ofII-VI or otherwise) arising out of their service toII-VI or to another corporation, partnership, joint venture, trust or other enterprise at the request ofII-VI.II-VI will not indemnify any director or officer in connection with a proceeding initiated by such director or officer (other than a proceeding to enforce such person’s right to indemnification under theII-VIBy-Laws) unless such proceeding was authorized by theII-VI Board. The right to indemnification conferred by this provision includes payment of all reasonable expenses (including attorney’s fees), judgments, fines and amounts paid in settlement in connection with such action, suit or proceeding. Section 6.04 of theII-VIBy-Laws permitsII-VI to indemnify any employee or agent ofII-VI who is not a director or officer, with such scope and effect as determined byII-VI.

Section 6.06 of theII-VIBy-Laws permitsII-VI to purchase and maintain insurance to protect itself and any director, officer, agent or employee against any liability asserted against and incurred by such person in respect of such person’s service, whether or notII-VI would have the power to indemnify such person against such liability by law or under the provisions of theII-VIBy-Laws.

II-VI has entered into agreements with its directors and officers pursuant to whichII-VI has agreed to provide for the indemnification of and the advancing of expenses to each such indemnitee to the fullest extent (whether partial or complete) permitted by law and as set forth in the applicable agreement, and, to the extent insurance is maintained, for the continued coverage of each such indemnitee underII-VI’s directors’ and officers’ liability insurance policies. To the fullest extent permissible by applicable law, if the indemnification provided for in each such agreement is unavailable to the applicable indemnitee for any reason whatsoever,II-VI, in lieu of indemnifying such indemnitee, shall contribute to the amount incurred such indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for expenses, in connection with any claim relating to an indemnifiable event under such agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such claim in order to reflect (i) the relative benefits received byII-VI and such indemnitee as a result of the event(s) and/or transaction(s) giving rise to such claim; and/or (ii) the relative fault ofII-VI (and its directors, officers, employees and agents) and such indemnitee in connection with such event(s) and/or transaction(s).

The indemnification described in the preceding paragraphs may include indemnification against liabilities arising under the Securities Act. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controllingII-VI pursuant to the foregoing provisions,II-VI has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 22. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

• to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

• to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration

II-3

statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

• to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

• any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

• any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

• the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

• any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-4

(c) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(d) The registrant undertakes that every prospectus (i) that is filed pursuant to the paragraph immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(e) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(f) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(g) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
