The exchange offer expires at 5:00 p.m., New York City time, on July 13, 2020, unless Cigna extends the offer. You may withdraw tenders of Old Notes at any time prior to the expiration of the exchange offer. The exchange offer is not subject to any condition other than that it will not violate applicable law or interpretations of the staff of the Securities and Exchange Commission (the “SEC”) and that no proceedings with respect to the exchange offer have been instituted or threatened in any court or by any governmental agency.

Principal Terms of the Exchange Notes:

The terms of the Exchange Notes to be issued in the exchange offer are substantially identical in all material respects to the Old Notes, except that the Exchange Notes will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the registration rights agreement. No public market currently exists for the Old Notes. Cigna does not intend to list the Exchange Notes on any securities exchange, and, therefore, no active public market is anticipated.

The Exchange Notes will be unsecured, unsubordinated obligations of Cigna and will rank equally in right of payment with all of Cigna’s existing and future unsecured, unsubordinated indebtedness.

You should carefully consider the risk factors beginning on page of this prospectus before participating in the exchange offer.

Each broker-dealer that receives Exchange Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. The letter of transmittal states that, by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes that were acquired by such broker-dealer as a result of market-making or other trading activities. Cigna has agreed that, for a period of up to 180 days after the expiration date of the exchange offer, if requested by one or more such broker-dealers, Cigna will amend or supplement this prospectus in order to expedite or facilitate the disposition of any Exchange Notes by any such broker-dealers. See “Plan of Distribution.”

None of the SEC, any state securities commission or other regulatory agency has approved or disapproved of the Exchange Notes or the exchange offer or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is June 12, 2020.

Exchange Offer

Cigna will exchange its Exchange Notes for a like aggregate principal amount and maturity of its Old Notes as provided in the registration rights agreement related to the Old Notes. The exchange offer is intended to satisfy the rights granted to holders of the Old Notes in that agreement. After the exchange offer is complete you will no longer be entitled to any exchange or registration rights with respect to your Notes.

Resales

Based on an interpretation by the staff of the SEC set forth in no-action letters issued to third parties, Cigna believes that the Exchange Notes may be offered for resale, resold and otherwise transferred by you (unless you are Cigna’s “affiliate” within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that you:

•
are acquiring the Exchange Notes in the ordinary course of business; and

•
have not engaged in, do not intend to engage in, and have no arrangement or understanding with any person to participate in a distribution of the Exchange Notes.

By signing the letter of transmittal and exchanging your Old Notes for Exchange Notes, as described below, you will be making representations to this effect.

Each participating broker-dealer that receives Exchange Notes for its own account pursuant to the exchange offer in exchange for the Old Notes that were acquired as a result of market-making or other trading activity must acknowledge that it will deliver a prospectus in connection with any resale of the Exchange Notes. See “Plan of Distribution.”

Any holder of Old Notes who:

•
is Cigna’s affiliate;

3

•
does not acquire the Exchange Notes in the ordinary course of its business; or

•
cannot rely on the position of the staff of the SEC expressed in Exxon Capital Holdings Corporation, Morgan Stanley & Co. Incorporated or similar no-action letters;

must, in the absence of an exemption, comply with registration and prospectus delivery requirements of the Securities Act in connection with the resale of the Exchange Notes. Cigna will not assume, nor will Cigna indemnify you against, any liability you may incur under the Securities Act or state or local securities laws if you transfer any Exchange Notes issued to you in the exchange offer absent compliance with the applicable registration and prospectus delivery requirements or an applicable exemption.

If applicable law or applicable interpretations of the staff of the SEC do not permit Cigna to effect the exchange offer, or if the exchange offer is not consummated by October 11, 2020 for any reason, or upon the request of holders of the notes under certain circumstances, Cigna will be required to file, and use commercially reasonable efforts to cause to become effective, a shelf registration statement under the Securities Act which would cover resales of the Old Notes. See “Terms of the Exchange Offer—Additional Obligations.”

Expiration Time

The exchange offer will expire at 5:00 p.m., New York City time, on July 13, 2020, or such later date and time to which Cigna extends it. Cigna does not currently intend to extend the expiration time.

Conditions to the Exchange Offer

The exchange offer is subject to the following conditions, which Cigna may waive:

•
the exchange offer does not violate applicable law or applicable interpretations of the staff of the SEC; and

•
there is no action or proceeding instituted or threatened in any court or by any governmental agency with respect to this exchange offer, which, in Cigna’s judgment, could reasonably be expected to impair Cigna’s ability to proceed with the exchange offer.

See “Terms of the Exchange Offer—Conditions to the Exchange Offer.”

Procedures for Tendering the Old Notes

If you wish to accept and participate in this exchange offer, you must complete, sign and date the accompanying letter of transmittal, or a copy of the letter of transmittal, according to the instructions

4

contained in this prospectus and the letter of transmittal. You must also mail, electronically deliver or otherwise deliver the completed, executed letter of transmittal or the copy thereof, together with the Old Notes and any other required documents, to the exchange agent at the address set forth on the cover of the letter of transmittal. If you hold Old Notes through The Depository Trust Company (“DTC”) and wish to participate in the exchange offer, you must comply with the Automated Tender Offer Program procedures of DTC described herein.

By signing or agreeing to be bound by the letter of transmittal, or, in the case of book-entry transfer, an agent’s message in lieu of the letter of transmittal, you will represent to Cigna that, among other things:

•
any Exchange Notes that you receive will be acquired in the ordinary course of your business;

•
you have no arrangement or understanding with any person or entity to participate in the distribution of the Exchange Notes;

•
if you are a broker-dealer that will receive Exchange Notes for your own account in exchange for Old Notes that were acquired as a result of market-making activities, that you will deliver a prospectus, as required by law, in connection with any resale of the Exchange Notes; and

•
you are not an “affiliate” of Cigna as defined in Rule 405 under the Securities Act.

Special Procedures for Beneficial Owners

If you are a beneficial owner whose Old Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your Old Notes in the exchange offer, you should promptly contact the person in whose name the Old Notes are registered and instruct that person to tender on your behalf. If you wish to tender in the exchange offer on your own behalf, prior to completing and executing the letter of transmittal and delivering the certificates for your Old Notes, you must either make appropriate arrangements to register ownership of the Old Notes in your name or obtain a properly completed bond power from the person in whose name the Old Notes are registered. The transfer of registered ownership may take considerable time and may not be able to be completed prior to the expiration time.

If you are a beneficial owner that holds Old Notes through Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), or Clearstream Banking, société anonyme (“Clearstream”), and wish

5

to tender your Old Notes, contact Euroclear or Clearstream directly to ascertain their procedure for tendering Old Notes and comply with such procedure.

Withdrawal of Tenders

A tender of Old Notes pursuant to the exchange offer may be withdrawn at any time prior to the expiration time. To withdraw, you must send a written or facsimile transmission notice of withdrawal to the exchange agent at its address indicated under “Terms of the Exchange Offer—Exchange Agent” before the expiration time of the exchange offer.

Acceptance of the Old Notes and Delivery of Exchange Notes

If all the conditions to the completion of this exchange offer are satisfied, Cigna will accept any and all Old Notes that are properly tendered in this exchange offer and not properly withdrawn before the expiration time. Cigna will return any Old Notes that Cigna does not accept for exchange to its registered holder at its expense promptly after the expiration time. Cigna will deliver the Exchange Notes to the registered holders of Old Notes accepted for exchange promptly after the expiration time and acceptance of such Old Notes. Please refer to the section in this prospectus entitled “Terms of the Exchange Offer—Acceptance of Old Notes for Exchange; Delivery of Exchange Notes.”

Effect on Holders of Old Notes

As a result of making, and upon acceptance for exchange of all validly tendered Old Notes pursuant to the terms of, the exchange offer, Cigna will have fulfilled a covenant contained in the registration rights agreement. If you are a holder of Old Notes and do not tender your Old Notes in the exchange offer, you will continue to hold your Old Notes and you will be entitled to all the rights and limitations applicable to the Old Notes in the indenture, except for any rights under the registration rights agreement that by their terms terminate upon the consummation of the exchange offer. See “Terms of the Exchange Offer—Purpose and Effect of the Exchange Offer.”

Consequences of Failure to Exchange

All untendered Old Notes will continue to be subject to the restrictions on transfer provided for in the Old Notes and in the indenture. In general, the Old Notes may not be offered or sold unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state or local securities laws. The trading market for your Old Notes will become more limited to the extent that other holders of Old Notes participate in the exchange offer. Following consummation of the exchange offer, Cigna will not be required to register under the Securities Act any Old Notes that remain outstanding, except in the limited circumstances in which it is obligated to file a shelf registration statement for certain holders of Old Notes not eligible to participate in the exchange offer

6

pursuant to the registration rights agreement. If your Old Notes are not tendered and accepted in the exchange offer, it may become more difficult for you to sell or transfer your Old Notes. See “Terms of the Exchange Offer—Additional Obligations” and “Risk Factors.”

Material U.S. Federal Income Tax Considerations

The exchange of Old Notes for Exchange Notes in the exchange offer will not constitute a taxable exchange for U.S. federal income tax purposes. See “Material U.S. Federal Income Tax Considerations.”

Optional Redemption

We may redeem the Exchange Notes (other than the 8.30% 2023 Exchange Notes, the 7.65% 2023 Exchange Notes and the 7.875% 2027 Exchange Notes), in whole or in part, at any time or from time to time at the redemption prices set forth under “Description of Notes—Optional Redemption.”

Ranking

The Exchange Notes will be our unsecured and unsubordinated obligations and will rank equally with all of our existing and future unsecured and unsubordinated indebtedness and senior in right of payment to all of our future indebtedness that is subordinated in right of payment to the Exchange Notes. The Exchange Notes will effectively rank junior to any of our existing and future secured indebtedness to the extent of the assets securing that indebtedness and will be structurally subordinated to any indebtedness and other liabilities of our subsidiaries.

See “Description of Notes—Ranking.”

Use of Proceeds

Cigna will not receive any cash proceeds from the issuance of the Exchange Notes. In consideration for issuing the Exchange Notes as contemplated in this prospectus, Cigna will receive in exchange Old Notes in like principal amount, which will be cancelled and, as such, will not result in any increase in Cigna’s indebtedness.

12

See “Use of Proceeds.”

Change of Control—Redemption at the Option of the Holders

Other than with respect to the 8.30% 2023 Exchange Notes, the 7.65% 2023 Exchange Notes, the 7.875% 2027 Exchange Notes, the 8.30% 2033 Step-Down Exchange Notes and the 6.150% 2036 Exchange Notes, a Change of Control Triggering Event (as defined under “Description of Notes—Change of Control Offer”) will occur with respect to Exchange Notes of a series if both a Change of Control and a Below Investment Grade Rating Event (each as defined under “Description of Notes—Change of Control Offer”) occur with respect to the Exchange Notes of such series, in which case, unless we have exercised our right to redeem the Exchange Notes of such series, as described under “Description of Notes—Optional Redemption,” we will be required to make an offer to repurchase all of the Exchange Notes of such series at a price equal to 101% of the principal amount of the Exchange Notes of such series, plus any accrued and unpaid interest to, but excluding, the date of repurchase. See “Description of Notes—Change of Control Offer.”

Covenants

The Indenture (as defined herein) limits our ability to consolidate with or merge with or into any other person (other than in a merger or consolidation in which we are the surviving person) or sell our property or assets as, or substantially as, an entirety to any person. The Indenture also contains limitations on liens on common stock of our Designated Subsidiaries (as defined herein). Each of these covenants is subject to important qualifications and limitations.

See “Description of Notes—Limitations on Liens on Common Stock of Designated Subsidiaries” and “Description of Notes—Consolidation, Merger and Sale of Assets.”

Minimum Denominations

The Exchange Notes will be issued and may be transferred only in minimum denominations of $2,000 (other than the 8.30% 2023 Exchange Notes, the 7.65% 2023 Exchange Notes, the 7.875% 2027 Exchange Notes and the 8.30% Step-Down Exchange Notes, collectively the “$1,000 Minimum Denomination Exchange Notes,” which will be issued and may be transferred only in minimum denominations of $1,000) and multiples of $1,000 in excess thereof. See “Description of Notes—General.”

Risk Factors

For a discussion of factors you should carefully consider before deciding to purchase the Exchange Notes, see “Forward-Looking Statements” and “Risk Factors” beginning on pages ii and 15 respectively, of this prospectus and the “Risk Factors” discussed in Cigna’s Annual Report on Form 10-K for the year ended December 31, 2019 and Cigna’s Quarterly

13

Report on Form 10-Q for the quarterly period ended March 31, 2020, which documents are in each case incorporated by reference in this prospectus.

No Public Markets

The Exchange Notes are new securities and there are currently no established trading markets for the Exchange Notes. As a result, liquid markets for the Exchange Notes may not be available if you try to sell your Exchange Notes. Cigna does not intend to apply to list the Exchange Notes on any national securities exchange or for inclusion of the Exchange Notes on any automated dealer quotation system.

Trustee

The Trustee for the Exchange Notes will be U.S. Bank National Association. See “Description of Notes—Concerning Our Relationship with the Trustee.”

Governing Law

The Exchange Notes and the Indenture will be governed by the laws of the State of New York. See “Description of Notes—Governing Law.”

RISK FACTORS

Investing in the Exchange Notes involves risks. Prospective investors should consider carefully all of the information set forth in this prospectus, any free writing prospectus filed by us with the SEC and the documents incorporated by reference herein. In particular, you should carefully consider the factors discussed below and under “Risk Factors” included in our annual report on Form 10-K for the fiscal year ended December 31, 2019 and our quarterly report on Form 10-Q for the quarterly period ended March 31, 2020.

Risks Related to the Exchange Notes

The Indenture does not limit the amount of debt we may incur or restrict our ability to engage in other transactions that may adversely affect holders of a series of the Exchange Notes.

The Indenture under which the Exchange Notes will be issued will not limit the amount of debt that we may incur. The Indenture does not contain any financial covenants or other provisions that would afford the holders of such series of the Exchange Notes any substantial protection in the event we participate in a highly leveraged transaction. In addition, the Indenture does not limit our ability to pay dividends, make distributions or repurchase shares of our common stock. Any such transaction could adversely affect you.

The Exchange Notes of each series will be subject to prior claims of secured creditors.

The Exchange Notes of each series will be our unsecured and unsubordinated obligations and will rank equally with all of our existing and future unsecured and unsubordinated indebtedness and senior in right of payment to all of our future indebtedness that is subordinated in right of payment to the Exchange Notes. At such times, such Exchange Notes will effectively rank junior to any of our existing and future secured indebtedness to the extent of the assets securing that indebtedness, and will be structurally subordinated to any indebtedness and other liabilities of our subsidiaries.

The Indenture governing the Exchange Notes will permit us and our subsidiaries to incur secured debt under specified circumstances. If we incur any debt secured by our or its assets, these assets will be subject to the prior claims of the secured creditors, and in the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding, these pledged assets would be available to satisfy secured obligations before any payment could be made on the Exchange Notes. To the extent that such assets could not satisfy in full any such secured obligations, the holders of such obligations would have a claim for any shortfall that would rank equally in right of payment with the Exchange Notes. In that case, we might not have sufficient assets remaining to pay amounts due on any or all of the Exchange Notes.

As a holding company, we will require cash from our subsidiaries to make payments on the Exchange Notes.

We are a holding company and, as such, our cash flow and our consequent ability to service our indebtedness, including the Exchange Notes, will be dependent upon the earnings of our subsidiaries and the distribution of those earnings to us or upon the payment of funds to us by those subsidiaries. Moreover, our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the Exchange Notes. The payment of dividends and the making of loans and advances to us by our subsidiaries may be subject to contractual or statutory restrictions, will be contingent upon the earnings of those subsidiaries and will be subject to various business considerations. As a holding company, if we are unable to obtain cash from our subsidiaries, we may be unable to fund required payments in respect of the Exchange Notes.

Active trading markets for the Exchange Notes of any series may not develop.

There are no existing trading markets for the Exchange Notes of any series and we do not intend to apply for listing of any series of the Exchange Notes on any securities exchange or any automated quotation system. Accordingly, there can be no assurance that any trading markets for the Exchange Notes of any series will ever develop or will be maintained. If a trading market does not develop or is not maintained for the Exchange Notes of any series, you may find it difficult or impossible to resell such Exchange Notes. Further, there can be no assurance as to the liquidity of any market that may develop for any of the Exchange Notes of any series, your ability to sell the Exchange Notes or the price at which you will be able to sell the Exchange Notes. Future trading prices of any of the Exchange Notes of any series will depend on many factors, including prevailing interest rates, our financial condition and results of operations, the then-current ratings assigned to us and/or our

15

debt securities and the markets for similar securities. Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including the time remaining to the maturity of an applicable series of the Exchange Notes, the outstanding amount of the Exchange Notes of such series, the terms related to optional redemption of such series of the Exchange Notes, and the level, direction and volatility of market interest rates generally.

The credit ratings for the Exchange Notes of any series could be lowered or withdrawn in the future.

We expect that each series of the Exchange Notes will be rated by one or more nationally recognized statistical rating organizations. A rating is not a recommendation to purchase, hold or sell debt securities, since a rating does not predict the market price of a particular security or its suitability for a particular investor. Any rating organization that rates a series of the Exchange Notes may lower its rating or decide not to continue to rate such series of the Exchange Notes in its sole discretion. The ratings of the Exchange Notes of any series will be based primarily on the rating organization’s assessment of the likelihood of timely payment of interest when due and the payment of principal on the maturity date. Any downgrade or withdrawal of a rating by a rating agency that rates a series of the Exchange Notes could have an adverse effect on the trading prices or liquidity of the Exchange Notes of such series.

We may choose to redeem the Exchange Notes of certain series prior to maturity.

We may redeem the Exchange Notes of any series (other than the 8.30% 2023 Exchange Notes, the 7.65% 2023 Exchange Notes and the 7.875% 2027 Exchange Notes), in whole or in part, at any time or from time to time. See “Description of Notes—Optional Redemption.”

Although the Exchange Notes contain provisions designed to compensate you for the lost value of such Exchange Notes if we redeem some or all of such Exchange Notes prior to maturity, they are only an approximation of this lost value and may not adequately compensate you. Furthermore, depending on prevailing interest rates at the time of any such redemption, you may not be able to reinvest the redemption proceeds in a comparable security at an interest rate as high as the interest rate of the Exchange Notes being redeemed or at an interest rate that would otherwise compensate you for any lost value as a result of any redemption of Exchange Notes.

We may not be able to purchase all of the Exchange Notes upon a Change of Control Triggering Event, which would result in a default under the Exchange Notes.

We will be required to offer to purchase the Exchange Notes (other than the 8.30% 2023 Exchange Notes, the 7.65% 2023 Exchange Notes, the 7.875% 2027 Exchange Notes, the 8.30% 2033 Step-Down Exchange Notes and the 6.150% 2036 Exchange Notes) upon the occurrence of a “Change of Control Triggering Event” as provided in the Indenture. See “Description of Notes—Change of Control Offer.” However, we may not have sufficient funds to purchase the Exchange Notes in cash at such time. In addition, our ability to purchase the Exchange Notes for cash may be limited by law or the terms of other agreements relating to our debt outstanding at the time. The failure to make such purchase would result in a default under each series of the Exchange Notes, as applicable.

Federal and state fraudulent transfer laws may permit a court to void the Exchange Notes, subordinate claims in respect of the Exchange Notes and require holders of the Exchange Notes to return payments received and, if that occurs, you may not receive any payments on the Exchange Notes.

Federal and state fraudulent transfer laws may permit a court to void the Exchange Notes, subordinate claims in respect of the Exchange Notes and require holders of the Exchange Notes to return payments received and, if that occurs, you may not receive any payments on the Exchange Notes. Federal and state fraudulent transfer and conveyance statutes may apply to the issuance of the Exchange Notes. Under federal bankruptcy law and comparable provisions of state fraudulent transfer or conveyance laws, which may vary from state to state, the Exchange Notes could be voided as a fraudulent transfer or conveyance if (1) we issued the Exchange Notes with the intent of hindering, delaying or defrauding creditors or (2) we received less than reasonably equivalent value or fair consideration in return for either issuing the Exchange Notes and, in the case of (2) only, one of the following was also true at the time thereof:

• we were insolvent on the date of the issuance of the Exchange Notes;

16

• we were rendered insolvent by reason of the issuance of the Exchange Notes;

• the issuance of the Exchange Notes left us with an unreasonably small amount of capital to carry on the business; or

• we intended to, or believed that we would, incur debts beyond our ability to pay such debts as they mature.

As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or a valid antecedent debt is secured or satisfied.

We cannot be certain as to the standards a court would use to determine whether or not we were solvent at the relevant time. Generally, however, an entity would be considered insolvent if, at the time it incurred indebtedness:

• the sum of its debts, including contingent liabilities, was greater than the fair value of all its assets;

• the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or

• it could not pay its debts as they become due.

If a court were to find that the issuance of the Exchange Notes was a fraudulent transfer or conveyance, the court could void the payment obligations under the Exchange Notes or subordinate the Exchange Notes to our presently existing and future indebtedness. In the event of a finding that a fraudulent transfer or conveyance occurred, you may not receive any repayment on the Exchange Notes.

Furthermore, in the event that a bankruptcy case were to be commenced under the bankruptcy code, we could be subject to claims, with respect to any payments made within 90 days prior to the commencement of such a case, that we were insolvent at the time any such payments were made and that all or a portion of such payments, which could include repayments of amounts due under the Exchange Notes might be deemed to constitute a preference, under the bankruptcy code, and that such payments should be voided by the bankruptcy court and recovered from the recipients for the benefit of the entire bankruptcy estate.

Risks Related to the Exchange Offer

You may have difficulty selling the Old Notes that you do not exchange.

If you do not exchange your Old Notes for Exchange Notes in the exchange offer, you will continue to be subject to the restrictions on transfer of your Old Notes described in the legend on your Old Notes and we will not be required to offer another opportunity for you to exchange your Old Notes for registered notes. The restrictions on transfer of your Old Notes arise because Cigna issued the Old Notes under exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws. In general, you may offer or sell the Old Notes only if they are registered under the Securities Act and applicable state securities laws or offered and sold under an exemption from these requirements. We do not intend to register the Old Notes under the Securities Act. To the extent Old Notes are tendered and accepted in the exchange offer, the trading market, if any, for the remaining Old Notes would be adversely affected. See “Terms of the Exchange Offer—Consequences of Failure to Exchange” for a discussion of the possible consequences of failing to exchange your Old Notes.

Broker-dealers or noteholders may become subject to the registration and prospectus delivery requirements of the Securities Act.

Any broker-dealer that exchanges its Old Notes in the exchange offer for the purpose of participating in a distribution of the Exchange Notes, or resells Exchange Notes that were received by it for its own account in the exchange offer, may be deemed to have received restricted securities and may be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction by that broker-dealer. Any profit on the resale of the Exchange Notes and any commission or concessions received by a broker-dealer may be deemed to be underwriting compensation under the Securities Act.

In addition to broker-dealers, any noteholder that exchanges its Old Notes in the exchange offer for the purpose of participating in a distribution of the Exchange Notes may be deemed to have received restricted

17

securities and may be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction by that noteholder.

Consummation of the exchange offer may not occur.

The exchange offer is subject to the satisfaction of certain conditions. See “Terms of the Exchange Offer—Conditions to the Exchange Offer.” Even if the exchange offer is completed, it may not be completed on the schedule described in this prospectus. Accordingly, holders participating in the exchange offer may have to wait longer than expected to receive their Exchange Notes, during which time such holders will not be able to effect transfers of their Old Notes tendered in the exchange offer.

Until we announce whether we have accepted valid tenders of Old Notes for exchange pursuant to the exchange offer, no assurance can be given that the exchange offer will be completed. In addition, subject to applicable law and as provided in this prospectus, we may, in our sole discretion, extend, re-open, amend, waive any condition of or terminate the exchange offer at any time before our announcement of whether we will accept valid tenders of Old Notes for exchange pursuant to the exchange offer, which we expect to make as soon as reasonably practicable after the expiration date.

18

USE OF PROCEEDS

Cigna will not receive any cash proceeds from the issuance of the Exchange Notes. In consideration for issuing the Exchange Notes as contemplated in this prospectus, Cigna will receive in exchange Old Notes in like principal amount, which will be cancelled and, as such, will not result in any increase in Cigna’s indebtedness.

TERMS OF THE EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

Cigna and the dealer managers entered into a registration rights agreement (the “registration rights agreement”) with respect to the Old Notes on October 11, 2019. Pursuant to the registration rights agreement, Cigna agreed to:

• use commercially reasonable efforts to (1) cause to be filed a registration statement on an appropriate registration form with respect to a registered offer to exchange each series of Old Notes for Exchange Notes with terms substantially identical in all material respects to such series of Old Notes (except that the Exchange Notes will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the registration rights agreement) and (2) have such registration statement become effective on or before October 11, 2020, which is referred to as the Target Registration Date, and if requested by one or more participating broker-dealers (as defined below), remain effective until 180 days after the expiration time of the exchange offer for use by such participating broker-dealers; and

• commence the exchange offer for each series promptly after the exchange offer registration statement is declared effective by the SEC and use commercially reasonable efforts to complete the exchange offer for such series not later than 60 days after such effective date.

After the SEC declares the exchange offer registration statement effective, Cigna will offer the Exchange Notes in return for the Old Notes. The exchange offer will remain open for at least 20 business days (or longer if required by applicable law) after the date Cigna mails and/or electronically delivers notice of the exchange offer to the holders of Old Notes. For each Old Note surrendered to Cigna pursuant to the exchange offer, the holder of the Old Note will receive an Exchange Note having a principal amount equal to that of the surrendered Old Note. Interest on each Exchange Note will accrue from the last interest payment date on which interest was paid on the Old Note surrendered in exchange thereof or, if no interest has been paid on such Old Note, from the date of its original issue.

Under existing SEC interpretations, Exchange Notes acquired in a registered exchange offer by holders of Old Notes are freely transferable without further registration under the Securities Act if the holder of the Exchange Notes represents that it is acquiring the Exchange Notes in the ordinary course of its business, that it has no arrangement or understanding to participate in the distribution of the Exchange Notes and that it is not an affiliate of Cigna, as such terms are interpreted by the SEC, provided that broker-dealers (“participating broker-dealers”) receiving Exchange Notes in a registered exchange offer will have a prospectus delivery requirement with respect to resales of such Exchange Notes. The SEC has taken the position that participating broker-dealers may fulfill their prospectus delivery requirements with respect to Exchange Notes (other than a resale of an unsold allotment from the original sale of the Old Notes) with the prospectus contained in the exchange offer registration statement relating to such Exchange Notes.

This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes that were acquired by such broker-dealer as a result of market-making or other trading activities. Cigna has agreed that, for a period of up to 180 days after the expiration date of the exchange offer, if requested by one or more such broker-dealers, Cigna will amend or supplement this prospectus in order to expedite or facilitate the disposition of any Exchange Notes by any such broker-dealers.

A holder of Old Notes who wishes to exchange its Old Notes for Exchange Notes in the exchange offer will be required to represent that (1) any Exchange Notes to be received by it will be acquired in the ordinary course of its business, (2) at the time of the commencement of the exchange offer, it has no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Notes in violation of the provisions of the Securities Act, (3) it is not an “affiliate” (within the meaning of Rule 405 under the Securities Act) of Cigna, (4) if such holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Notes and (5) if such holder is a broker-dealer that will receive the Exchange Notes for its own account in exchange for the Old Notes that were acquired as a result of market-making or other trading activities, then such holder will deliver a prospectus (or, to the extent permitted by law, make available a prospectus to purchasers) in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

21

Following October 11, 2020, if Cigna receives a written request from any dealer manager representing that it holds Old Notes that are or were ineligible to be exchanged in the exchange offer for Exchange Notes, Cigna will use its commercially reasonable efforts to cause to become effective a shelf registration statement relating to resales of the Old Notes. See “Exchange Offer; Registration Rights.”

The registration rights agreement provides, among other things, that if Cigna has not exchanged Exchange Notes for all Old Notes validly tendered in accordance with the terms of the exchange offer on or prior to October 11, 2020 or, if a shelf registration statement is required, such shelf registration statement is not declared effective on or prior to October 11, 2020, the annual interest rate on the registrable securities will increase initially by 0.25% for the first 90-day period immediately following the occurrence of such registration default. The annual interest rate on the registrable securities will increase by an additional 0.25% for each subsequent 90-day period during which the registration default continues, up to a maximum additional interest rate of 1.00% per year. If Cigna corrects the registration default, the accrual of such special interest will cease, and the interest rate on the registrable securities will revert to the original level. See “Exchange Offer; Registration Rights.”

Resale of Exchange Notes

Based on a series of no-action letters of the staff of the SEC issued to third parties, the Exchange Notes issued in the exchange offer may be offered for resale, resold and otherwise transferred without registration under the Securities Act, and without delivering a prospectus that satisfies the requirements of Section 10 of the Securities Act, if the holder of Old Notes who wishes to exchange its Old Notes for Exchange Notes can make the representations set forth below under “—Procedures for Tendering the Old Notes.” However, if such holder intends to participate in a distribution of the Exchange Notes, is a broker-dealer that acquired the Old Notes directly from Cigna for its own account in the initial offering of the Old Notes and not as a result of market-making activities or other trading activities or is an “affiliate” of Cigna as defined in Rule 405 under the Securities Act, such holder will not be eligible to participate in the exchange offer, and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with the resale of its Old Notes. See “—Additional Obligations.”

A broker-dealer that has acquired Old Notes as a result of market-making or other trading activities has to deliver a prospectus in order to resell any new notes it receives for its own account in the exchange offer. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes that were acquired by such broker-dealer as a result of market-making or other trading activities. Cigna has agreed that, for a period of up to 180 days after the expiration date of the exchange offer, if requested by one or more such broker-dealers, Cigna will amend or supplement this prospectus in order to expedite or facilitate the disposition of any Exchange Notes by any such broker-dealers. See “Plan of Distribution” for more information regarding broker-dealers.

The exchange offer is not being made to, nor will Cigna accept tenders for exchange from, holders of Old Notes in any jurisdiction in which this exchange offer or the acceptance of the exchange offer would not be in compliance with the securities or blue sky laws.

The exchange offer is not subject to any federal or state regulatory requirements or approvals other than securities laws and blue sky laws.

Terms of the Exchange Offer

Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, Cigna will accept for exchange any Old Notes properly tendered and not withdrawn prior to the expiration time. Old Notes (other than $1,000 Minimum Denomination Old Notes) may only be tendered in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000; provided, that the untendered portion of any Old Note (other than any $1,000 Minimum Denomination Old Note) must be in a minimum denomination of $2,000. Cigna will issue $2,000 principal amount or an integral multiple of $1,000 of Exchange Notes (other than $1,000 Minimum Denomination Exchange Notes) in exchange for a corresponding principal amount of Old Notes surrendered in the exchange offer. $1,000 Minimum Denomination Old Notes may only be tendered in denominations of $1,000 and integral multiples of $1,000 in excess of thereof; provided, that the untendered portion of any $1,000 Minimum Denomination Old Note must be in a minimum denomination of $1,000. Cigna will issue $1,000 principal amount or an integral multiple of $1,000 Minimum Denomination Exchange Notes in

22

exchange for a corresponding principal amount of Old Notes surrendered in the exchange offer. In exchange for each Old Note surrendered in the exchange offer, Cigna will issue Exchange Notes with a like principal amount.

The form and terms of the Exchange Notes will be substantially identical in all material respects to the form and terms of the Old Notes, except that the Exchange Notes will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the registration rights agreement.

The Exchange Notes will evidence the same debt as the Old Notes. The Exchange Notes will be issued under and entitled to the benefits of the same indenture that authorized the issuance of the Old Notes. Consequently, each series of Exchange Notes and the corresponding Old Notes will be treated as a single class of debt securities under that indenture.

The exchange offer is not conditioned upon any minimum aggregate principal amount of Exchange Notes being tendered for exchange.

This prospectus and the letter of transmittal are being sent to all registered holders of Old Notes. There will be no fixed record date for determining registered holders of Old Notes entitled to participate in the exchange offer.

Cigna intends to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act and the Exchange Act and the rules and regulations of the SEC. Old Notes that are not tendered for exchange in the exchange offer will remain outstanding and continue to accrue interest and will be entitled to the rights and benefits such holders have under the indenture relating to the Old Notes.

Cigna will be deemed to have accepted for exchange properly tendered Old Notes when Cigna has given oral or written notice (if oral, to be promptly confirmed in writing) of the acceptance to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the Exchange Notes from Cigna and delivering Exchange Notes to such holders. Subject to the terms of the exchange offer and the registration rights agreement, Cigna expressly reserves the right to amend or terminate the exchange offer, and to not accept for exchange any Old Notes not previously accepted for exchange, upon the occurrence of any of the conditions specified below under the caption “—Conditions to the Exchange Offer.”

Cigna will pay all charges and expenses, other than those brokerage commissions or fees or transfer taxes described below or in the letter of transmittal, in connection with the exchange offer. It is important that you read the section labeled “—Fees and Expenses” below for more details regarding fees and expenses incurred in the exchange offer.

Expiration Time; Extensions; Amendments

The exchange offer will expire at 5:00 p.m., New York City time, on July 13, 2020, unless, in Cigna’s sole discretion, Cigna extends it.

23

In order to extend the exchange offer, Cigna will notify the exchange agent orally or in writing (if oral, to be promptly confirmed in writing) of any extension. Cigna will notify in writing or by public announcement the registered holders of Old Notes of the extension no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration time.

Cigna expressly reserves the right, in its sole discretion:

• to delay accepting for exchange any Old Notes due to an extension of the exchange offer;

• to extend the exchange offer or to terminate the exchange offer and to refuse to accept Old Notes not previously accepted if any of the conditions set forth below under “—Conditions to the Exchange Offer” have not been satisfied by giving oral or written notice (if oral, to be promptly confirmed in writing) of such extension or termination to the exchange agent; or

• subject to the terms of the registration rights agreement, to amend the terms of the exchange offer in any manner.

Any such delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice or public announcement thereof to the registered holders of Old Notes. If Cigna amends the exchange offer in a manner that Cigna determines to constitute a material change, Cigna will promptly disclose such amendment in a manner reasonably calculated to inform the holders of Old Notes of such amendment.

Without limiting the manner in which Cigna may choose to make public announcements of any delay in acceptance, extension, termination or amendment of the exchange offer, Cigna shall have no obligation to publish, advertise or otherwise communicate any such public announcement other than by issuing a timely press release to a financial news service. If Cigna makes any material change to this exchange offer, Cigna will disclose this change by means of a post-effective amendment to the registration statement that includes this prospectus and will distribute an amended or supplemented prospectus to each registered holder of Old Notes. In addition, Cigna will extend this exchange offer for an additional five to ten business days as required by the Exchange Act, depending on the significance of the amendment, if the exchange offer would otherwise expire during that period. Cigna will promptly notify the exchange agent by oral notice, promptly confirmed in writing, or written notice of any delay in acceptance, extension, termination or amendment of this exchange offer.

Conditions to the Exchange Offer

Notwithstanding any other terms of the exchange offer, Cigna will not be required to accept for exchange, or exchange any Exchange Notes for, any Old Notes, and Cigna may terminate the exchange offer as provided in this prospectus before accepting any Old Notes for exchange, if Cigna determines in its sole discretion:

• the exchange offer would violate applicable law or any applicable interpretation of the staff of the SEC; or

• any action or proceeding has been instituted or threatened in any court or by any governmental agency with respect to the exchange offer.

In addition, Cigna will not be obligated to accept for exchange the Old Notes of any holder that has not made the representations described in the letter of transmittal and under “—Purpose and Effect of the Exchange Offer,” “—Procedures for Tendering the Old Notes” and “Plan of Distribution,” and such other representations as may be reasonably necessary under applicable SEC rules, regulations or interpretations to make available to it an appropriate form for registration of the Exchange Notes under the Securities Act.

Cigna expressly reserves the right, at any time or at various times, to extend the period of time during which the exchange offer is open. Consequently, Cigna may delay acceptance of any Old Notes by giving oral or written notice of such extension to the registered holders of the Old Notes as promptly as practicable. During any such extensions, all Old Notes previously tendered will remain subject to the exchange offer, and Cigna may accept them for exchange unless they have been previously withdrawn. Cigna will return any Old Notes that Cigna does not accept for exchange for any reason without expense to their tendering holder promptly after the expiration or termination of the exchange offer.

Cigna expressly reserves the right to amend or terminate the exchange offer, and to reject for exchange any Old Notes not previously accepted for exchange, upon the occurrence of any of the conditions of the exchange

24

offer specified above. Cigna will give oral or written notice or public announcement of any extension, amendment, non-acceptance or termination to the registered holders of the Old Notes as promptly as practicable. In the case of any extension, such notice will be issued no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration time.

These conditions are for Cigna’s sole benefit, and Cigna may assert them regardless of the circumstances that may give rise to them or waive them in whole or in part at any or at various times in Cigna’s sole discretion; provided that any waiver of a condition of tender will apply to all Old Notes and not only to particular Old Notes. If Cigna fails at any time to exercise any of the foregoing rights, that failure will not constitute a waiver of such right. Each such right will be deemed an ongoing right that Cigna may assert at any time or at various times.

In addition, Cigna will not accept for exchange any Old Notes tendered, and will not issue Exchange Notes in exchange for any such Old Notes, if at such time any stop order will be threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939 (the “Trust Indenture Act”).

Procedures for Tendering the Old Notes

Except as described below, a holder tendering Old Notes must, prior to 5:00 p.m., New York City time, on the expiration date:

• transmit a properly completed and duly executed letter of transmittal, including all other documents required by the letter of transmittal, to the Exchange Agent, at the address listed below under the heading “—Exchange Agent;” or

• if Old Notes are tendered in accordance with the book-entry procedures described below, the tendering holder must transmit an agent’s message (described below) to the Exchange Agent.

Transmittal will be deemed made only when actually received or confirmed by the Exchange Agent.

In addition, the Exchange Agent must receive, before 5:00 p.m., New York City time, on the expiration date:

• certificates for the Old Notes; or

• confirmation of book-entry transfer of the Old Notes into the Exchange Agent’s account at DTC, the book-entry transfer facility.

The term “agent’s message” means a computer-generated message, transmitted by DTC to, and received by, the Exchange Agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgment from the tendering participant that such participant has received and agrees to be bound by, and makes the representations and warranties contained in, the letter of transmittal and that Cigna may enforce the letter of transmittal against such participant.

The method of delivery of Old Notes, letters of transmittal and all other required documents is at the holder’s election and risk. If delivery is by mail, Cigna recommends that holders use registered mail, properly insured, with return receipt requested. In all cases, holders should allow sufficient time to assure timely delivery. Holders should not send letters of transmittal or Old Notes to anyone other than the Exchange Agent.

If the holder is a beneficial owner whose Old Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, and wishes to tender, such holder should promptly instruct the registered holder to tender on its behalf. Any registered holder that is a participant in DTC’s book-entry transfer facility system may make book-entry delivery of the Old Notes by causing DTC to transfer the Old Notes into the Exchange Agent’s account.

Signatures on a letter of transmittal or a notice of withdrawal must be guaranteed unless the Old Notes surrendered for exchange are tendered:

• by a registered holder of the Old Notes that has not completed the box entitled “Special Issuance Instructions” or “Special Delivery Instructions” on the letter of transmittal; or

• for the account of an “eligible institution.”

25

If signatures on a letter of transmittal or a notice of withdrawal are required to be guaranteed, the guarantees must be by an “eligible institution.” An “eligible institution” is a financial institution, including most banks, savings and loan associations and brokerage houses, that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program.

Cigna will reasonably determine all questions as to the validity, form and eligibility of Old Notes tendered for exchange and all questions concerning the timing of receipts and acceptance of tenders. These determinations will be final and binding.

Cigna reserves the right to reject any particular Old Note not validly tendered, or any acceptance that might, in our judgment, be unlawful. Cigna also reserves the right to waive any defects or irregularities with respect to the form of, or procedures applicable to, the tender of any particular Old Note before the expiration date. Unless waived, any defects or irregularities in connection with tenders of Old Notes must be cured before the expiration date of the exchange offer. Neither Cigna, the Exchange Agent nor any other person will be under any duty to give notification of any defect or irregularity in any tender of the Old Notes. Neither Cigna, the Exchange Agent nor any other person will incur any liability for failing to give notification of any defect or irregularity.

If the letter of transmittal is signed by a person other than the registered holder of Old Notes, the letter of transmittal must be accompanied by a physical certificate representing the Old Notes endorsed by the registered holder or written instrument of transfer or exchange in satisfactory form, duly executed by the registered holder, in either case with the signature guaranteed by an eligible institution. In addition, in either case, the original endorsement or the instrument of transfer must be signed exactly as the name of any registered holder appears on the Old Notes.

If the letter of transmittal or any Old Notes or powers of attorney are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, these persons should so indicate when signing. Unless waived by Cigna, proper evidence satisfactory to us of their authority to so act must be submitted.

By signing or agreeing to be bound by the letter of transmittal, each tendering holder of Old Notes will represent, among other things, that:

• it is not an affiliate of ours or, if an affiliate of ours, will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable in connection with the resale of the Exchange Notes;

• the Exchange Notes will be acquired in the ordinary course of its business;

• it is not participating, does not intend to participate, and has no arrangement or understanding with anyone to participate, in the distribution (within the meaning of the Securities Act) of the Exchange Notes;

• it is not a broker-dealer that purchased any of the Old Notes from us or any of our affiliates for resale pursuant to Rule 144A or any other available exemption under the Securities Act; and

• if such holder is a broker-dealer that will receive Exchange Notes for its own account in exchange for Old Notes that were acquired as a result of market-making activities or other trading activities, that it will deliver a prospectus (or to the extent permitted by law, make available a prospectus to purchasers) in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

Acceptance of Old Notes for Exchange; Delivery of Exchange Notes

Upon satisfaction of all of the conditions to the Exchange Offer, Cigna will accept, promptly after the expiration date, all Old Notes validly tendered. We will issue the Exchange Notes promptly after the expiration of the Exchange Offer and acceptance of the Old Notes. See “—Conditions to the Exchange Offer” below. For purposes of the Exchange Offer, we will be deemed to have accepted validly tendered Old Notes for exchange when, as and if we have given written notice of such acceptance to the Exchange Agent.

For each Old Note accepted for exchange, the holder of the Old Note will receive an Exchange Note having a principal amount equal to that of the surrendered Old Note. Interest on each Exchange Note will accrue from the last interest payment date on which interest was paid on the Old Note surrendered in exchange thereof or, if

26

no interest has been paid on such Old Note, from the date of its original issue. Old Notes accepted for exchange will cease to accrue interest from and after the date of completion of the Exchange Offer. Holders of Old Notes whose Old Notes are accepted for exchange will not receive any payment for accrued interest on the Old Notes otherwise payable on any interest payment date, the record date for which occurs on or after completion of the Exchange Offer and will be deemed to have waived their rights to receive such accrued interest on the Old Notes.

In all cases, issuance of Exchange Notes for Old Notes will be made only after timely receipt by the Exchange Agent of:

• certificates for the Old Notes or a book-entry confirmation of the deposit of the Old Notes into the Exchange Agent’s account at the book-entry transfer facility;

• a properly completed and duly executed letter of transmittal or a transmitted agent’s message; and

• all other required documents.

Unaccepted or non-exchanged Old Notes will be returned without expense to the tendering holder of the Old Notes promptly after the expiration of the Exchange Offer. In the case of Old Notes tendered by book-entry transfer in accordance with the book-entry procedures described below, the non-exchanged Old Notes will be returned or recredited promptly after the expiration of the Exchange Offer.

Book-Entry Transfer

The Exchange Agent will make a request to establish an account for the Old Notes at DTC for purposes of the Exchange Offer within two business days after the date of this prospectus. Any financial institution that is a participant in DTC’s systems and is tendering Old Notes must make book-entry delivery of the Old Notes by causing DTC to transfer those Old Notes into the Exchange Agent’s account at DTC in accordance with DTC’s procedures for transfer, including its Automated Tender Offer Program, or ATOP, procedures. The participant should transmit its acceptance to DTC prior to 5:00 p.m., New York City time, on the expiration date. DTC will verify this acceptance, execute a book-entry transfer of the tendered Old Notes into the Exchange Agent’s account at DTC and then send to the Exchange Agent confirmation of this book-entry transfer, which confirmation must be received prior to 5:00 p.m., New York City time, on the expiration date. The confirmation of this book-entry transfer will include an agent’s message confirming that DTC has received an express acknowledgment from the participant that the participant has received and agrees to be bound by the letter of transmittal and that Cigna may enforce the letter of transmittal against the participant. Delivery of Exchange Notes issued in the Exchange Offer may be effected through book-entry transfer at DTC. However, the letter of transmittal (or an agent’s message in lieu thereof), with any required signature guarantees and any other required documents, must be transmitted to, and received by, the Exchange Agent at the address listed below under “—Exchange Agent” (or its account at DTC with respect to an agent’s message) prior to 5:00 p.m., New York City time, on the expiration date.

Withdrawal of Tenders

Except as otherwise provided in this prospectus, holders of Old Notes may withdraw their tenders at any time prior to the expiration of the exchange offer. For a withdrawal to be effective, the exchange agent must receive a written notice (which may be by facsimile transmission or letter) of withdrawal at one of the addresses set forth below under “—Exchange Agent,” or the holder must comply with the appropriate procedure of DTC’s ATOP system.

Any such notice of withdrawal must specify the name of the person who tendered the Old Notes to be withdrawn, identify the Old Notes to be withdrawn (including the principal amount of such Old Notes and, if applicable, the registration numbers and total principal amount of such Old Notes) and, where certificates for Old Notes have been transmitted, specify the name in which such Old Notes were registered if different from that of the withdrawing holder. Any such notice of withdrawal must also be signed by the person having tendered the Old Notes to be withdrawn in the same manner as the original signature on the letter of transmittal by which these Old Notes were tendered, including any required signature guarantees, or be accompanied by documents of transfer sufficient to permit the trustee for the Old Notes to register the transfer of these Notes into the name of the person having made the original tender and withdrawing the tender and, if applicable because the Old Notes have been tendered through the book-entry procedure, specify the name and number of the participant’s account at DTC to be credited if different than that of the person having tendered the Old Notes to be withdrawn.

27

If certificates for Old Notes have been delivered or otherwise identified to the exchange agent, then, prior to the release of such certificates, the withdrawing holder must also submit the serial numbers of the particular certificates to be withdrawn and a signed notice of withdrawal with signatures guaranteed by an eligible guarantor institution unless such holder is an eligible guarantor institution.

If Old Notes have been tendered pursuant to the procedure for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Old Notes and otherwise comply with the procedures of such facility. Cigna will determine all questions as to the validity, form and eligibility (including time of receipt) of such notices, and Cigna’s determination shall be final and binding on all parties. Cigna will deem any Old Notes so withdrawn not to have been validly tendered for exchange for purposes of the exchange offer. Any Old Notes that have been tendered for exchange but that are not exchanged for any reason will be returned to their holder without cost to the holder (or, in the case of Old Notes tendered by book-entry transfer into the exchange agent’s account of DTC according to the procedures described above, such Old Notes will be credited to an account maintained with DTC for Old Notes) promptly after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn Old Notes may be retendered by following one of the procedures described under “—Procedures for Tendering the Old Notes” above at any time prior to the expiration time.

Exchange Agent

U.S. Bank National Association has been appointed as exchange agent for the exchange offer. You should direct questions and requests for assistance or requests for additional copies of this prospectus, or the letter of transmittal, to the exchange agent addressed as follows:

By Overnight Courier, Registered/ Certified Mail and by Hand:

U.S. Bank National Association
Corporate Trust Services

St. Paul, Minnesota 55107
Attn: Specialized Finance

Delivery to an address other than as set forth above or transmission via facsimile other than as set forth above does not constitute a valid delivery to the exchange agent.

Fees and Expenses

Cigna will not make any payment to brokers, dealers or others soliciting acceptances of the Exchange Offer. Cigna has agreed to pay all expenses incident to the Exchange Offer other than commissions or concessions of any broker-dealers and will indemnify the holders of the Old Notes and the Exchange Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act. The cash expenses to be incurred in connection with the Exchange Offer, including out-of-pocket expenses for the Exchange Agent, will be paid by Cigna. Cigna will not pay for underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of Old Notes by a holder.

Consequences of Failure to Exchange

Holders of Old Notes who do not exchange their Old Notes for Exchange Notes under the exchange offer will remain subject to the restrictions on transfer of such Old Notes as set forth in the legend printed on the Old Notes as a consequence of the issuance of the Old Notes pursuant to the exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws and otherwise as set forth in the offering circular distributed in connection with the private placement offering of the Old Notes.

28

In general, you may not offer or sell the Old Notes unless they are registered under the Securities Act or if the offer or sale is exempt from registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement related to the Old Notes, Cigna does not intend to register resales of the Old Notes under the Securities Act. Based on interpretations of the SEC staff, Exchange Notes issued pursuant to the exchange offer may be offered for resale, resold or otherwise transferred by their holders (other than any such holder that is Cigna’s “affiliate” within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act; provided that the holders acquired the Exchange Notes in the ordinary course of the holders’ business and the holders have no arrangement or understanding with respect to the distribution of the Exchange Notes to be acquired in the exchange offer. Any holder who tenders in the exchange offer for the purpose of participating in a distribution of the Exchange Notes could not rely on the applicable interpretations of the SEC and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction.

Cigna does not currently anticipate that Cigna will register under the Securities Act any Old Notes that remain outstanding after completion of the exchange offer.

Accounting Treatment

Cigna will record the Exchange Notes in Cigna’s accounting records at the same carrying value as the Old Notes, as reflected in Cigna’s accounting records on the date of exchange. Accordingly, Cigna will not recognize any gain or loss for accounting purposes in connection with the exchange offer. Cigna will expense the costs of the exchange offer and amortize the remaining unamortized expenses related to the issuance of the Old Notes over the term of the Exchange Notes.

Additional Obligations

In the registration rights agreement, Cigna agreed that under certain circumstances that it would file a shelf registration statement with the SEC covering resales of notes by holders thereof if:

• Cigna determines that the exchange offer is not available under applicable law or if applicable interpretations of the staff of the SEC do not permit Cigna to effect the exchange offer;

• for any reason, Cigna does not consummate the exchange offer by the Target Registration Date; or

• following the Target Registration Date, Cigna receives a written request from any dealer manager representing that it holds Old Notes that are or were ineligible to be exchanged in any such exchange offer, Cigna shall use its commercially reasonable efforts to cause to become effective a shelf registration statement providing for the sale of all the registrable securities of such series by the Holders thereof.

In such an event, we would be under a continuing obligation to use commercially reasonable efforts to keep the shelf registration statement effective and to provide copies of the latest version of the prospectus contained therein to any broker-dealer that requests copies for use in a resale.

Other

Participation in the exchange offer is voluntary, and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your own decision on what action to take.

Cigna may in the future seek to acquire untendered Old Notes in the open market or privately negotiated transactions, through subsequent exchange offers or otherwise. Cigna has no present plans to acquire any Old Notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered Old Notes.

29

DESCRIPTION OF NOTES

On October 11, 2019, Cigna issued the Old Notes under an indenture dated as of September 17, 2018 between Halfmoon Parent, Inc. (now known as Cigna Corporation) and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the Supplemental Indenture No. 3 dated as of October 11, 2019 (the indenture, as so supplemented, the “Indenture”).

The terms of the Exchange Notes will be substantially identical in all material respects to the Old Notes, except that the Exchange Notes will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the registration rights agreement. The trustee will authenticate and deliver Exchange Notes for original issue only in exchange for a like principal amount of Old Notes.

Except as the context otherwise requires, (1) the term “Notes” means the 4.000% Notes due 2022, 8.30% Notes due 2023, 7.65% Notes due 2023, 3.250% Notes due 2025, 7.875% Notes due 2027, 3.050% Notes due 2027, 8.30% Step-Down Notes due 2033, 6.150% Notes due 2036, 5.875% Notes due 2041, 5.375% Notes due 2042, 3.875% Notes due 2047, 3.900% Notes due 2022, 3.050% Notes due 2022, 3.000% Notes due 2023, 3.50% Notes due 2024, 4.500% Notes due 2026, 3.400% Notes due 2027, 6.125% Notes due 2041, 4.800% Notes due 2046 and 4.125% Notes due 2020 (including the corresponding Exchange Notes offered for exchange hereby, the corresponding Old Notes and any additional notes that Cigna may issue from time to time under the Indenture). Capitalized words used in this “Description of Notes” that are not defined in this “Description of Notes” are used herein as defined elsewhere in this prospectus.

The following summary of certain provisions of the Indenture and the Notes does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the Indenture and the Notes, including the definitions of certain terms therein and those terms, if any, made part thereof by the Trust Indenture Act. In this “Description of Notes” section, when we refer to the “Company,” “we,” “our,” or “us,” we refer to Cigna Corporation and any successor obligor and not to any of its subsidiaries.

The Indenture does not restrict our ability to incur additional indebtedness, other than certain indebtedness secured by liens on common stock of our Designated Subsidiaries. The Indenture contains negative covenants that apply to us; however, these covenants contain important exceptions. See “—Limitations on Liens on Common Stock of Designated Subsidiaries” and “—Consolidation, Merger and Sale of Assets.”

For purposes of this Description of Notes, the term “stated maturity” of the principal of any series of Notes shall mean the date upon which such series of Notes matures as described in the preceding paragraphs under this heading “—General.”

In the future, we may, without the consent of the holders of any series of Notes, increase the principal amounts of any series of Notes offered hereby. The Exchange Notes of each series, the corresponding Old Notes and any additional notes of such series subsequently issued under the Indenture will be treated as a single series or class for all purposes under the Indenture, including, without limitation, waivers, amendments and redemptions.

We will issue the Notes only in fully registered form, without coupons, in denominations of $2,000 (other than the 8.30% 2023 Notes, the 7.65% 2023 Notes, the 7.875% 2027 Notes and the 8.30% Step-Down Notes, which we will issue in denominations of $1,000) and multiples of $1,000 in excess thereof.

32

The Notes are not subject to any sinking fund provision.

In each case, we:

• make payments on the Notes held in certificated form at the designated office of the Trustee; and

• may make payments by wire transfer for Notes held in book-entry form or by check mailed to the address of the person entitled to the payment as it appears in the note register.

Interest on the Notes

The Notes of each series bear interest at the applicable annual rate described above under the heading “—General.” Interest on the Notes that are Exchange Notes will accrue from the last interest payment date on which interest was paid or duly provided for on the Old Notes surrendered in exchange therefor. The holders of the Old Notes that are accepted for exchange will be deemed to have waived the right to receive payment of accrued interest on those Old Notes from the last interest payment date on which interest was paid or duly provided for on such Old Notes to the date of issuance of the Exchange Notes. Interest on the Old Notes accepted for exchange will cease to accrue upon issuance of the Exchange Notes. Interest is payable on the Notes that are Exchange Notes beginning with the first interest payment date following the consummation of the exchange offer.

Interest is payable on the Notes semi-annually in arrears on the dates set forth in this paragraph and on the relevant maturity date, to the persons in whose names such Notes are registered on the record date; provided, however, that interest payable on the relevant maturity date or any relevant redemption date will be payable to the persons to whom the principal of such Notes is payable.

• Interest on the 4.000% 2022 Notes is payable on February 15 and August 15 of each year;

• interest on the 8.30% 2023 Notes is payable on January 15 and July 15 of each year;

• interest on the 7.65% 2023 Notes is payable on March 1 and September 1 of each year;

• interest on the 3.250% 2025 Notes is payable on April 15 and October 15 of each year;

• interest on the 7.875% 2027 Notes is payable on May 15 and November 15 of each year;

• interest on the 3.050% 2027 Notes is payable on April 15 and October 15 of each year;

• interest on the 8.30% 2033 Step-Down Notes is payable on January 15 and July 15 of each year;

• interest on the 6.150% 2036 Notes is payable on May 15 and November 15 of each year;

• interest on the 5.875% 2041 Notes is payable on March 15 and September 15 of each year;

• interest on the 5.375% 2042 Notes is payable on February 15 and August 15 of each year;

• interest on the 3.875% 2047 Notes is payable on April 15 and October 15 of each year;

• interest on the 3.900% 2022 Notes is payable on February 15 and August 15 of each year;

• interest on the 3.050% 2022 Notes is payable on May 30 and November 30 of each year;

• interest on the 3.000% 2023 Notes is payable on January 15 and July 15 of each year;

• interest on the 3.50% 2024 Notes is payable on June 15 and December 15 of each year;

• interest on the 4.500% 2026 Notes is payable on February 25 and August 25 of each year;

• interest on the 3.400% 2027 Notes is payable on March 1 and September 1 of each year;

• interest on the 6.125% 2041 Notes is payable on May 15 and November 15 of each year;

• interest on the 4.800% 2046 Notes is payable on January 15 and July 15 of each year; and

• interest on the 4.125% 2020 Notes is payable on March 15 and September 15 of each year.

33

If the date on which a payment of interest or principal on the Notes is scheduled to be paid is not a business day, then that interest or principal will be paid on the next succeeding business day, and no further interest will accrue as a result of such delay. Interest with respect to the Notes accrues on the basis of a 360-day year consisting of twelve 30-day months.

A “record date” is the close of business on the date that is fifteen calendar days prior to the date on which interest is scheduled to be paid, regardless of whether such date is a business day; provided that if any of the Notes are held by a securities depositary in book-entry form, the record date for such Notes will be the close of business on the business day immediately preceding the date on which interest is scheduled to be paid.

A “business day” is any day other than a Saturday, Sunday or other day on which banking institutions in The City of New York are authorized or obligated by law or executive order to be closed.

Ranking

The Notes are our unsecured and unsubordinated obligations and rank equally with all of our existing and future senior unsecured and unsubordinated indebtedness and senior to all of our future subordinated indebtedness. The Notes effectively rank junior to any of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness, and are structurally subordinated to any indebtedness and other liabilities of our subsidiaries.

A significant part of our operations are conducted through subsidiaries; therefore, a significant portion of our cash flow, and consequently, our ability to service debt, including the Notes, are dependent upon the earnings of our subsidiaries and the transfer of funds by those subsidiaries to us in the form of dividends or other transfers.

In addition, holders of the Notes have a junior position to claims of creditors against our subsidiaries, including policyholders, trade creditors, debtholders, secured creditors, taxing authorities, guarantee holders and any preferred shareholders, except to the extent that we are recognized as a creditor of our subsidiary. Any claims of the Company as the creditor of its subsidiary would be subordinate to any security interest in the assets of such subsidiary and any indebtedness of such subsidiary senior to that held by us.

In addition to general state law restrictions on payments of dividends and other distributions to shareholders applicable to all corporations, health maintenance organizations and insurance companies, including certain of the Company’s indirect subsidiaries, are subject to further state regulations that, among other things, may require those companies to maintain certain levels of equity, and restrict the amount of dividends and other distributions that may be paid to the Company.

For purposes of these Optional Redemption provisions, the following definitions are applicable:

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes to be redeemed (assuming, for the purpose of the Notes listed in TABLE THREE, that such of Notes mature on the Par Call Date applicable thereto).

“Comparable Treasury Price” means, with respect to any redemption date for any Notes, the average of all Reference Treasury Dealer Quotations obtained by us.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us from time to time.

“Reference Treasury Dealer” means each of J.P. Morgan Securities LLC, Deutsche Bank Securities Inc. and Wells Fargo Securities, LLC and their respective successors. If any Reference Treasury Dealer ceases to be a primary U.S. government securities dealer in the United States (a “Primary Treasury Dealer”), we will substitute another Primary Treasury Dealer for that dealer.

36

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the maturity date for the Notes to be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate shall be interpolated or extrapolated from those yields on a straight line basis, rounding to the nearest month), or (2) if the release referred to in clause (1) (or any successor release) is not published during the week preceding the calculation date or does not contain the yields referred to above, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

The Treasury Rate will be calculated on the third business day preceding the redemption date.

Notice of any redemption will be mailed or otherwise delivered in accordance with the applicable procedures of DTC (as defined below) at least 15 days but not more than 60 days before the redemption date to each holder of the Notes to be redeemed.

Unless we default in payment of the redemption price, interest will cease to accrue on the Notes or portion of the Notes called for redemption on and after the redemption date.

We may at any time and from time to time purchase Notes in the open market, by tender offer, through privately negotiated transactions or otherwise.

Change of Control Offer

This “—Change of Control Offer” section does not apply to the 8.30% 2023 Notes, the 7.65% 2023 Notes, the 7.875% 2027 Notes, the 8.30% 2033 Step-Down Notes and the 6.150% 2036 Notes.

If a Change of Control Triggering Event (as defined below) occurs with respect to any series of Notes (other than the 8.30% 2023 Notes, the 7.65% 2023 Notes, the 7.875% 2027 Notes, the 8.30% 2033 Step-Down Notes and the 6.150% 2036 Notes), unless we have exercised our right to redeem such Notes in full, as described under “Optional Redemption” above, we will make an offer to each holder (the “Change of Control Offer”) of such Notes to repurchase any and all of such holder’s Notes of such series, at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes of such series repurchased, plus any accrued and unpaid interest thereon to, but excluding, the date of repurchase (the “Change of Control Payment”).

Within 30 days following any Change of Control Triggering Event, we will be required to send a notice to holders of Notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date will be no less than 15 days and no more than 60 days from the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required by the Notes, and described in such notice.

We must comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control repurchase provisions of the Notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control repurchase provisions of the Notes by virtue of such conflicts. We will not be required to offer to repurchase the Notes upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and the third party repurchases on the applicable date all Notes properly tendered and

37

not withdrawn under its offer; provided that for all purposes of the Notes and the Indenture, a failure by such third party to comply with the requirements of such offer and to complete such offer shall be treated as a failure by us to comply with our obligations to offer to purchase the Notes unless we promptly make an offer to repurchase the Notes at 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon, to the date of repurchase, which shall be no later than 30 days after the third party’s scheduled Change of Control Payment Date.

On the Change of Control Payment Date, we will, to the extent lawful:

• accept or cause a third party to accept for payment all Notes properly tendered pursuant to the Change of Control Offer;

• deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes properly tendered; and

• deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an officer’s certificate stating the principal amount of the Notes being purchased.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of Cigna and its subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the applicability of the requirement that we offer to repurchase the Notes as a result of a sale, transfer, conveyance or other disposition of less than all of the assets of Cigna and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) may be uncertain.

For purposes of the foregoing discussion of the applicable Change of Control provisions, the following definitions are applicable:

“Below Investment Grade Rating Event” with respect to any series of Notes means such Notes are rated below all Investment Grade Ratings by at least two of the three Rating Agencies on any date from the earlier of (1) the occurrence of a Change of Control and (2) public notice of our intention to effect a Change of Control, in each case until the end of the 60-day period following public notice of the occurrence of the Change of Control; provided, however, that if (a) during such 60-day period, one or more Rating Agencies has publicly announced that it is considering the possible downgrade of such series of Notes, and (b) a downgrade by each of the Rating Agencies that has made such an announcement would result in a Below Investment Grade Rating Event, then such 60-day period shall be extended for such time as the rating of such series of Notes by any such Rating Agency remains under publicly announced consideration for possible downgrade to a rating below an Investment Grade Rating and a downgrade by such Rating Agency to a rating below an Investment Grade Rating could cause a Below Investment Grade Rating Event. Notwithstanding the foregoing, a rating event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a rating event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at our or the Trustee’s request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the rating event).

“Change of Control” means the occurrence of any of the following:

(1) direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries; or

(2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its subsidiaries becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of the Company’s voting stock;

38

provided, however, that a transaction will not be deemed to involve a Change of Control if (A) we become a wholly owned subsidiary of a holding company and (B)(x) the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s voting stock immediately prior to that transaction or (y) immediately following that transaction no person is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding company. For purposes of this definition, “voting stock” of a person means capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right to vote has been suspended by the happening of such a contingency.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Fitch” means Fitch Ratings Inc. and any successor to its rating agency business.

“Investment Grade Rating” means a rating by Moody’s equal to or higher than Baa3 (or the equivalent under a successor rating category of Moody’s), a rating by S&P equal to or higher than BBB– (or the equivalent under any successor rating category of S&P), a rating by Fitch equal to or higher than BBB– (or the equivalent under any successor rating category of Fitch), and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by us under the circumstances permitting us to select a replacement agency and in the manner for selecting a replacement agency, in each case as set forth in the definition of “Rating Agencies.”

“Moody’s” means Moody’s Investors Service, Inc. and any successor to its rating agency business.

“Rating Agencies” means (1) Moody’s, S&P and Fitch; and (2) if any or all of Moody’s, S&P or Fitch ceases to rate any series of Notes or fails to make a rating of any series of Notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act that we select (pursuant to a resolution of the Company’s Board of Directors) as a replacement agency for any of Moody’s, S&P or Fitch, or all of them, as the case may be, with respect to such series of Notes, as applicable.

“S&P” means Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business and any successor to its rating agency business.

Additional Notes

We may from time to time, without notice to or the consent of the holders of any series of Notes, create and issue further notes of any such series ranking equally with the Notes of such series (and being treated as a single class with the Notes of such series) in all respects; provided that if such additional notes are not fungible with the initial Notes of such series for U.S. federal income tax purposes, such additional notes will have a separate CUSIP number.

Limitations on Liens on Common Stock of Designated Subsidiaries

The Indenture provides that, so long as any of the Notes remain outstanding, we will not, and we will not permit any of our subsidiaries to, directly or indirectly, create, issue, assume, incur or guarantee any indebtedness for borrowed money secured by a mortgage, pledge, lien, security interest or other encumbrance of any nature on any of the common stock of a Designated Subsidiary, which common stock is directly or indirectly owned by us, unless the Notes and, if we so elect, any other of our indebtedness ranking on a parity with, or prior to, the Notes, shall be secured equally and ratably with, or prior to, such secured indebtedness for borrowed money so long as it is outstanding and is so secured.

“Designated Subsidiary” means each of Cigna Holding Company, Connecticut General Life Insurance Company, Life Insurance Company of North America, Express Scripts Holding Company, Express Scripts, Inc. and Medco Health Solutions, Inc., so long as it remains a subsidiary, or any subsidiary which is a successor of a Designated Subsidiary.

39

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into any other person (other than in a merger or consolidation in which we are the surviving person) or sell our properties and assets as, or substantially as, an entirety to any person unless:

• the person formed by the consolidation or with or into which we are merged or the person that purchases our properties and assets as, or substantially as, an entirety is the Company or any successor thereto or a corporation organized and validly existing under the laws of the United States of America, any State or the District of Columbia, and any such successor or purchaser expressly assumes the Company’s obligations on the Notes under a supplemental indenture;

• immediately after giving effect to the transaction no Event of Default shall have occurred and be continuing; and

• an officers’ certificate and opinion of counsel are delivered to the Trustee.

Upon compliance with the foregoing provisions, the successor or purchaser will succeed to, and be substituted for the Company under the Indenture with the same effect as if such successor or purchaser had been the original obligor under the Notes, and thereafter the Company will be relieved of all obligations and covenants under the Indenture and the Notes.

Events of Default and Notice Thereof

When we use the term “Event of Default” with respect to Notes of any series we mean:

• we fail to pay principal of, or premium, if any, on, any Notes of that series when due;

• we fail to pay interest, if any, on any Notes of that series when due and the failure continues for a period of 30 days;

• we fail to perform in any material respect any covenant in the Indenture not specified in the previous two bullet points (other than a covenant included in the Indenture solely for the benefit of a different series of debt securities) and the failure to perform continues for a period of 90 days after receipt of a specified written notice to us from the Trustee or holders of at least 25% in aggregate principal amount of the outstanding Notes of any relevant series of Notes; and

• certain events of bankruptcy, insolvency, reorganization, receivership or liquidation of the Company.

The Indenture also includes certain events of default related to subsidiary guarantees; such provisions are no longer operative with respect to the Notes.

An Event of Default with respect to Notes of a particular series may not constitute an Event of Default with respect to Notes of any other series.

If an Event of Default under the Indenture occurs with respect to the Notes of any series and is continuing, then the Trustee or the holders of at least 25% in principal amount of the outstanding Notes of that series may require us to repay immediately the entire principal amount of all outstanding Notes of that series; provided, however, that under certain circumstances the holders of a majority in aggregate principal amount of outstanding Notes of that series may rescind and annul such acceleration and its consequences.

The Indenture contains a provision entitling the Trustee, subject to the duty of the Trustee during a default to act with the required standard of care, to be indemnified by the holders of Notes before proceeding to exercise any right or power under that Indenture at the request of such holders. Subject to these provisions in the Indenture for the indemnification of the Trustee and certain other limitations, the holders of a majority in aggregate principal amount of the Notes of each affected series then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

The Indenture provides that the Trustee may withhold notice to the holders of the Notes of any default (except in payment of principal (or premium, if any) or interest, if any) if the Trustee considers it in the interest of the holders of the Notes to do so.

40

The Indenture provides that holders of at least 25% in aggregate principal amount of the outstanding Notes of any series may seek to institute a proceeding with respect to the Indenture or for any remedy thereunder only after:

• such holders previously gave written notice to the Trustee of a continuing Event of Default;

• such holders have made a written request to the Trustee to institute a proceeding;

• such holders have offered an indemnity reasonably satisfactory to the Trustee to institute a proceeding; and

• the Trustee shall not have received from the holders of a majority in aggregate principal amount of the outstanding Notes of that series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days.

These limitations will not apply, however, to a suit instituted by a holder of Notes for enforcement of payment of the principal of or premium, if any, or interest, if any, on or after the respective due dates expressed in such Notes.

The Indenture contains a covenant under which we are required to furnish to the Trustee an annual statement as to the compliance with all conditions and covenants of the Indenture.

Modification and Waiver

The Indenture provides that we, together with the Trustee, may enter into supplemental indentures or other instruments without the consent of the holders of Notes to:

• evidence the assumption by another person of our obligations;

• add covenants for the benefit of the holders of all or any series of Notes or surrender any right or power of the Company under the Indenture or the Notes;

• add any additional Events of Default;

• add or change the Indenture to permit or facilitate the issuance of Notes in bearer form or in uncertificated form;

• add to, change or eliminate a provision of the Indenture or the Notes if such addition, change or elimination does not apply to a Note created prior to the execution of such supplemental indenture or modify the rights of a holder of any Note with respect to such provision;

• secure any Note or perfect the security interest securing the Company’s obligations in respect of any Note;

• establish the form or terms of debt securities of any series;

• evidence the acceptance of appointment by a successor Trustee;

• add to any provision of an Indenture to the extent necessary to permit or facilitate defeasance and discharge of any series of Notes if such action does not adversely affect the interests of the holders of Notes in any material respect;

• cure any ambiguity or correct any inconsistency in the Indenture or make other changes, provided that any such action does not adversely affect the interests of the holders of Notes of any affected series in any material respect;

• add guarantees in respect of any Note;

• conform the text of the Indenture or the Notes to any provision of this “Description of Notes” or any other provision of this prospectus; or

• conform the Indenture or the Notes to any mandatory provision of law.

41

Other amendments and modifications of the Indenture may be made with the consent of the holders of not less than a majority of the aggregate principal amount of each series of the outstanding Notes affected by the amendment or modification; provided, however, no modification or amendment may, without the consent of the holder of each outstanding Note affected:

• change the stated maturity of the principal of (or premium, if any) or any installment of principal or interest, if any, on any such Note;

• reduce the principal amount of (or premium, if any) or the interest rate, if any, on any such Note;

• change the place or currency of payment of principal of (or premium if any) or the interest, if any, on any such Note;

• impair the right to institute suit for the enforcement of any such payment on or with respect to any such Note;

• reduce the percentage of holders of debt securities necessary to modify or amend the Indenture;

• modify the foregoing requirements or reduce the percentage of outstanding Notes necessary to waive compliance with certain provisions of the Indenture or for waiver of certain defaults.

The holders of at least a majority of the aggregate principal amount of the outstanding Notes of any series may, on behalf of all holders of that series, waive our required compliance with certain restrictive provisions of the Indenture and may waive any past default under the Indenture, except a default in the payment of principal, premium or interest or in the performance of certain covenants.

The Indenture also includes certain modification and waiver provisions related to subsidiary guarantees; such provisions are no longer operative with respect to the Notes.

Defeasance and Covenant Defeasance

If we deposit, in trust, with the Trustee (or other qualifying trustee), sufficient cash and/or specified government obligations (in the opinion of a nationally recognized firm of independent public accountants) to pay the principal of (and premium, if any) and interest and any other sums due on the scheduled due date for the Notes of a particular series, then at our option and subject to certain conditions (including the absence of an Event of Default):

• we will be discharged from our obligations with respect to the Notes of such series (which we refer to in this “Description of Notes” as a “legal defeasance”), or

• we will no longer be under any obligation to comply with the covenants described above under “— Limitations on Liens on Common Stock of Designated Subsidiaries” or “—Consolidation, Merger and Sale of Assets,” or the provisions of the Notes described under “—Change of Control Offer,” and any Event of Default relating to any failure to comply with such covenants will no longer apply to us (which we refer to in this prospectus as a “covenant defeasance”).

If we exercise our legal defeasance option, payment of such Notes may not be accelerated because of an Event of Default. If we exercise our covenant defeasance option, payment of such Notes may not be accelerated by reference to the covenants from which we have been released or pursuant to Events of Default referred to above which are no longer applicable. If we fail to comply with our remaining obligations with respect to such Notes after we exercise the covenant defeasance option and such Notes are declared due and payable because of the occurrence of any Event of Default, the amount of money and government obligations on deposit with the Trustee may be insufficient to pay amounts due on the Notes of such series at the time of the acceleration resulting from such Event of Default. However, we will remain liable for such payments.

Under current United States federal income tax laws, a legal defeasance would be treated as an exchange of the relevant Notes in which holders of those Notes might recognize gain or loss. Unless accompanied by other changes in the terms of the Notes, a covenant defeasance generally should not be treated as a taxable exchange. In order to exercise our defeasance options, we must deliver to the Trustee an opinion of counsel to the effect that the deposit and related defeasance would not cause the holders of the Notes of the relevant series to recognize income, gain or loss for Federal income tax purposes. In the case of legal defeasance, such opinion of counsel must be based on (a) an Internal Revenue Service ruling or (b) since the date of the Indenture, a change in the applicable United States Federal income tax law.

42

No Personal Liability of Incorporators, Stockholders, Officers, Directors, Employees or Agents

The Indenture provides that no recourse shall be had for the payment of principal, premium, if any, or interest, if any, on any Note, or for any claim based on or in respect of any Note or the Indenture or any supplemental indenture, against any incorporator, or against any past, present or future stockholder, officer, director, employee or agent of ours or of any successor person thereof under any law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. Each holder, by accepting the Notes, waives and releases all such liability.

Concerning Our Relationship with the Trustee

U.S. Bank National Association acts as Trustee under the Indenture. We maintain customary banking relationships in the ordinary course of business with the Trustee and its affiliates.

Governing Law

The Indenture and the Notes are governed by and construed in accordance with the laws of the State of New York, without regard to conflicts of laws principles thereof.

43

BOOK-ENTRY SETTLEMENT AND CLEARANCE

The Global Notes

Like the Old Notes, the Exchange Notes will be issued in the form of registered notes in global form, without interest coupons (the “global notes”).

Upon issuance, each of the global notes will be deposited with the Trustee as custodian for DTC and registered in the name of Cede & Co., as nominee of DTC.

Ownership of beneficial interests in each global note will be limited to persons who have accounts with DTC (“DTC participants”) or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

• upon deposit of each global note with DTC’s custodian, DTC will credit portions of the principal amount of the global note to the accounts of the DTC participants designated by the dealer managers; and

• ownership of beneficial interests in each global note will be shown on, and transfer of ownership of those interests will be effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the global note).

Beneficial interests in the global notes may not be exchanged for notes in physical, certificated form except in the limited circumstances described below.

Book-Entry Procedures for the Global Notes

All interests in the global notes will be subject to the operations and procedures of DTC, Euroclear and Clearstream, as applicable. We have provided the following summaries of those operations and procedures solely for the convenience of investors. The operations and procedures of each settlement system are controlled by that settlement system and may be changed at any time. Neither we nor the dealer managers are responsible for those operations or procedures.

DTC has advised us that it is:

• a limited purpose trust company organized under the laws of the State of New York;

• a “banking organization” within the meaning of the New York State Banking Law;

• a member of the U.S. Federal Reserve System;

• a “clearing corporation” within the meaning of the Uniform Commercial Code; and

• a “clearing agency” registered under Section 17A of the Securities Exchange Act of 1934.

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants.

DTC’s participants include securities brokers and dealers, including the dealer managers; banks and trust companies; clearing corporations and other organizations. Indirect access to DTC’s system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC’s nominee is the registered owner of a global note, that nominee will be considered the sole owner or holder of the Notes represented by that global note for all purposes under the Indenture. Except as provided below, owners of beneficial interests in a global note:

• will not be entitled to have the Notes represented by the global note registered in their names;

• will not receive or be entitled to receive physical, certificated notes; and

44

• will not be considered the owners or holders of the notes under the Indenture for any purpose, including with respect to the giving of any direction, instruction or approval to the Trustee under the Indenture.

As a result, each investor who owns a beneficial interest in a global note must rely on the procedures of DTC to exercise any rights of a holder of the Notes under the Indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

Payments of principal, premium (if any) and interest with respect to the Notes represented by a global note will be made by the Trustee to DTC’s nominee as the registered holder of the global note. Neither we nor the Trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global note, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those interests.

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC.

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same-day funds. Transfers between participants in Euroclear or Clearstream will be effected in the ordinary way under the rules and operating procedures of those systems.

Cross-market transfers between DTC participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected within DTC through the DTC participants that are acting as depositaries for Euroclear and Clearstream. To deliver or receive an interest in a global note held in a Euroclear or Clearstream account, an investor must send transfer instructions to Euroclear or Clearstream, as the case may be, under the rules and procedures of that system and within the established deadlines of that system. If the transaction meets its settlement requirements, Euroclear or Clearstream, as the case may be, will send instructions to its DTC depository to take action to effect final settlement by delivering or receiving interests in the relevant global notes in DTC, and making or receiving payment under normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the DTC depositaries that are acting for Euroclear or Clearstream.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant that purchases an interest in a global note from a DTC participant will be credited on the business day for Euroclear or Clearstream immediately following the DTC settlement date. Cash received in Euroclear or Clearstream from the sale of an interest in a global note to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Euroclear or Clearstream cash account as of the business day for Euroclear or Clearstream following the DTC settlement date.

DTC, Euroclear and Clearstream have agreed to the above procedures to facilitate transfers of interests in the global notes among participants in those settlement systems. However, the settlement systems are not obligated to perform these procedures and may discontinue or change these procedures at any time. Neither we nor the Trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their participants or indirect participants of their obligations under the rules and procedures governing their operations.

Certificated Notes

Notes of a series in physical, certificated form will be issued and delivered to each person that DTC identifies as a beneficial owner of the related Notes only if:

• DTC notifies us at any time that it is unwilling or unable to continue as depositary for the global notes of such series and a successor depositary is not appointed within 90 days;

• DTC ceases to be registered as a clearing agency under the Securities Exchange Act of 1934 and a successor depositary is not appointed within 90 days;

45

• we, at our option, notify the Trustee that we elect to cause the issuance of certificated notes of such series; or

• there shall have occurred and be continuing an Event of Default with respect to Notes of such series and DTC notifies the Trustee of its decision to exchange the global notes of such series for certificated notes of such series.

46

EXCHANGE OFFER; REGISTRATION RIGHTS

Cigna and the dealer managers entered into a registration rights agreement with respect to the Old Notes on October 11, 2019. In the agreement, Cigna agreed for the benefit of the holders of the Old Notes to use commercially reasonable efforts to (1) file a registration statement on an appropriate registration form with respect to a registered offer to exchange each series of Old Notes for Exchange Notes with terms substantially identical in all material respects to such series of Old Notes (except that the Exchange Notes will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the registration rights agreement) and (2) cause the registration statement to be declared effective under the Securities Act.

After the SEC declares the exchange offer registration statement effective, we will offer the Exchange Notes in return for the Old Notes. The exchange offer will remain open for at least 20 business days (or longer if required by applicable law) after the date Cigna mails and/or electronically delivers notice of the exchange offer to the holders of Old Notes. For each Old Note surrendered to Cigna under the exchange offer, the holders of such Old Note will receive an Exchange Note of such series of equal principal amount. Interest on each Exchange Note will accrue as described in “Description of Notes.” A holder of registrable securities that participates in the exchange offer will be required to make certain representations to Cigna. Cigna will use commercially reasonable efforts to complete the exchange offer for each series of Old Notes not later than 60 days after the exchange offer registration statement becomes effective. Under existing interpretations of the SEC contained in several no-action letters to third parties, the Exchange Notes will generally be freely transferable after the exchange offer without further registration under the Securities Act, except that any broker-dealer that participates in the exchange must deliver a prospectus meeting the requirements of the Securities Act when it resells the Exchange Notes. In addition, under applicable interpretations of the staff of the SEC, Cigna’s affiliates will not be permitted to exchange their Old Notes for registered Old Notes in the exchange offer.

Cigna agreed to make available, during the period required by the Securities Act, a prospectus meeting the requirements of the Securities Act for use by participating broker-dealers and other persons, if any, with similar prospectus delivery requirements for use in connection with any resale of Exchange Notes. Old Notes of any series not tendered in the exchange offer will bear interest at the rate set forth on the cover page of the related offering memorandum with respect to such series of Old Notes and be subject to all the terms and conditions specified in the indenture, including transfer restrictions, but will not retain any rights under the registration rights agreement (including with respect to increases in annual interest rate described below) after the consummation of the exchange offer.

In the event that Cigna determines that a registered exchange offer is not available under applicable law or may not be completed as soon as practicable after the last date for acceptance of Old Notes for exchange because it would violate any applicable law or applicable interpretations of the staff of the SEC or, if for any reason the exchange offer is not for any other reason completed by the later of (1) October 11, 2020 and (2) the 60th day after the effective date or upon receipt, following the later of (1) October 11, 2020 and (2) the 60th day after the effective date, of a written request from any dealer manager representing that it holds Old Notes that are or were ineligible to be exchanged in the exchange offer for Exchange Notes, Cigna will use its commercially reasonable efforts to cause to become effective a shelf registration statement relating to resales of the Old Notes. Cigna will, in the event of such a shelf registration, provide to each participating holder of Old Notes copies of a prospectus, notify each participating holder of Old Notes when the shelf registration statement has become effective and take certain other actions to permit resales of the Old Notes. A holder of registrable securities that sells Old Notes under the shelf registration statement generally will be required to make certain representations to Cigna, to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under the Securities Act in connection with those sales and will be bound by the provisions of the registration rights agreement that are applicable to such a holder of registrable securities (including certain indemnification obligations). Holders of registrable securities will also be required to suspend their use of the prospectus included in the shelf registration statement under specified circumstances upon receipt of notice from Cigna.

If a “registration default” (as defined below) occurs with respect to a series of registrable securities, then additional interest shall accrue on the principal amount of the Old Notes of a particular series that are registrable securities at a rate of 0.25% per annum (which rate will be increased by an additional 0.25% per annum for each subsequent 90-day period that such additional interest continues to accrue, provided that the rate at which such

47

additional interest accrues may in no event exceed 1.00% per annum). The additional interest will cease to accrue when all registration defaults are cured. The foregoing amounts shall not increase, even if more than one registration default has occurred and is continuing. Notwithstanding the foregoing, a holder of Old Notes who is not entitled to the benefits of the shelf registration statement shall not be entitled to any increase in the interest rate borne by the Old Notes as a result of a registration default that pertains to the shelf registration statement.

A “registration default” occurs if (1) Cigna has not exchanged Exchange Notes for all Old Notes validly tendered in accordance with the terms of the exchange offer on or prior to October 11, 2020 or, if a shelf registration statement is required, such shelf registration statement is not declared effective on or prior to October 11, 2020 or (2) if applicable, a shelf registration statement covering resales of the Old Notes has been declared effective and such shelf registration statement ceases to be effective or the prospectus contained therein ceases to be usable for resales of registrable securities (a) on more than two occasions of at least 30 consecutive days during the required effectiveness period or (b) at any time in any 12-month period during the required effectiveness period, and such failure to remain effective or be usable exists for more than 90 days (whether or not consecutive) in any 12-month period. A registration default is cured with respect to a series of Old Notes, and additional interest ceases to accrue on any registrable securities of a series of Old Notes, when the exchange offer is completed or the shelf registration statement is declared effective or the prospectus again becomes usable, as applicable, or such Old Notes cease to be “registrable securities.”

The registration rights agreement defines “registrable securities” initially to mean the Old Notes, and provides that Old Notes will cease to be registrable securities upon the earliest to occur of the following: (1) when a registration statement with respect to such Old Notes has become effective and such Old Notes have been exchanged or disposed of pursuant to such registration statement, (2) when such Old Notes cease to be outstanding and (3) when such Old Notes have been resold sold pursuant to Rule 144 under the Securities Act (but not Rule 144A) without regard to volume restrictions, provided that we shall have removed or caused to be removed any restrictive legend on the Old Notes.

Any amounts of additional interest due will be payable in cash on the same original interest payment dates as interest on the Old Notes is payable. The Exchange Notes will be accepted for clearance through DTC.

This summary of the provisions of the registration rights agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the registration rights agreement.

48

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations relating to the exchange of Old Notes for Exchange Notes pursuant to the exchange offer, but does not purport to be a complete analysis of all the potential tax considerations relating to the exchange offer. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, Treasury regulations promulgated thereunder, administrative rulings and pronouncements, and judicial decisions, all as in effect on the date of this prospectus and all of which are subject to change or to different interpretations, possibly with retroactive effect, which may result in U.S. federal income tax consequences different than those set forth below.

The exchange of Old Notes for Exchange Notes in the exchange offer will not constitute a taxable event to holders for U.S. federal income tax purposes. Consequently, you will not recognize gain or loss upon the exchange of an Old Note for an Exchange Note, the holding period of the Exchange Note will include the holding period of the Old Note exchanged therefor and the basis of the Exchange Note will be the same as the basis of the Old Note immediately before the exchange.

All holders considering the exchange of Old Notes for Exchange Notes should consult their own tax advisors concerning the U.S. federal income tax consequences in light of their particular circumstances as well as any consequences arising under the laws of any other taxing jurisdiction.

49

PLAN OF DISTRIBUTION

Each broker-dealer that receives Exchange Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Old Notes that were acquired by such broker-dealer as a result of market-making or other trading activities. Cigna has agreed that, for a period of up to 180 days after the expiration date of the exchange offer, if requested by one or more such broker-dealers, Cigna will amend or supplement this prospectus in order to expedite or facilitate the disposition of any Exchange Notes by any such broker-dealers.

Cigna will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to the exchange offer, and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an “underwriter” within the meaning of the Securities Act, and any profit on any such resale of Exchange Notes and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 180 days after the expiration time of the exchange offer, Cigna will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. Cigna has agreed to pay certain expenses incident to the exchange offer (including the expenses of one counsel for the holders of the Notes) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.
