UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

On May 12, 2016, Western Digital Corporation (“Western Digital” or “the Company”) completed its acquisition of SanDisk Corporation (“SanDisk”), pursuant to the Agreement and Plan of Merger (the “Merger Agreement”) dated October 21, 2015 among Western Digital, SanDisk and Schrader Acquisition Corporation (“Merger Sub”). Merger Sub was a direct wholly owned subsidiary of Western Digital Technologies, Inc. (“WDT”), which is a direct wholly owned subsidiary of Western Digital. At the closing of the acquisition, Merger Sub merged with and into SanDisk with SanDisk continuing as the surviving corporation and a wholly owned subsidiary of WDT (the “Merger”). Each issued and outstanding share of SanDisk common stock, other than shares of SanDisk common stock held in the treasury of SanDisk, shares of SanDisk common stock owned by stockholders who have validly exercised their appraisal rights under Delaware law and shares of SanDisk common stock owned by Western Digital or any subsidiary of Western Digital (including Merger Sub), was converted into the right to receive $67.50 per share in cash; and 0.2387 shares of Western Digital common stock per share of SanDisk common stock. Western Digital paid approximately $13.8 billion in cash and issued approximately 48.5 million shares of its common stock in consideration for the Merger.

The Company entered into new debt facilities with a borrowing capacity of $18.1 billion to, among other things, pay part of the purchase price, refinance existing debt of Western Digital and SanDisk, and pay transaction related fees and expenses (collectively, the “Financing Transactions”). The Financing Transactions consisted of the following new debt and debt repayments described below.

On April 13, 2016, the Company completed an offering of its $1.875 billion aggregate principal amount of 7.375% senior secured notes due 2023 (the “Secured Notes”) and $3.35 billion aggregate principal amount of 10.500% senior unsecured notes due 2024 (the “Unsecured Notes” and, together with the Secured Notes, the “Notes”). The Notes were issued pursuant to indentures (the “Indentures”) among the Company, certain of the Company’s material subsidiaries, and U.S. Bank National Association, as trustee (and as collateral agent with respect to the Secured Notes).

The Secured Notes and related guarantees are secured on an equal and ratable basis by liens on the same assets that secure indebtedness under the New Credit Agreement as described below and, as a result, will be effectively senior to the Unsecured Notes to the extent of the value of the assets that secure the Secured Notes and will be effectively pari passu with obligations under the New Credit Agreement. The Unsecured Notes and related guarantees will be effectively subordinated to all of the Company’s and each subsidiary guarantor’s present and future secured indebtedness (to the extent of the value of the assets securing such indebtedness), including, in the case of the Company and the subsidiary guarantors, the obligations under the Secured Notes and the Credit Facilities as described below. The Notes will be structurally subordinated in right of payment to all present and future indebtedness and all other liabilities of the Company’s subsidiaries that do not guarantee the Notes.

The Indentures contain certain restrictive covenants, including covenants limiting the Company’s and each guarantor subsidiary’s ability to incur, assume or guarantee additional indebtedness, pay dividends, make distributions or redeem or repurchase capital stock, effect dividends, loans or asset transfers from subsidiaries, create liens, make certain investments, sell or otherwise dispose of assets, place restrictions on the ability of restricted subsidiaries to make payments to the Company, consolidate, merge or sell all or substantially all of their assets, and enter into transactions with affiliates, and customary events of default.

On April 29, 2016, the Company entered into a new credit agreement (the “New Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and collateral agent (the “Administrative Agent”), and the lenders party thereto, which provides for secured loan facilities consisting of a $4.125 billion term loan facility (the “Term Loan A Facility”), a $3.75 billion term loan facility (the “U.S. Term Loan B Facility”), an €885 million term loan facility (the “Euro Term Loan B Facility” and, together with the U.S. Term Loan B Facility, the “Term Loan B Facilities”), and a $1.0 billion revolving credit facility (the “Revolving Credit Facility”) (these facilities, together with the Bridge Facility described below, the “Credit Facilities”). The Revolving Credit Facility includes a $200 million sublimit for letters of credit. The Term Loan B Facilities closed on April 29, 2016. Borrowings under the U.S. Term Loan B Facility bear interest at a rate per annum, at the Company’s option, of either an adjusted LIBOR rate (subject to a 0.75% floor) plus an applicable margin of 5.50% or at a base rate plus an applicable margin of 4.50%. The borrowings under the Euro Term Loan B Facility bear interest at a rate per annum equal to an adjusted EURIBOR rate (subject to a 0.75% floor) plus an applicable margin of 5.25%.

The Term Loan A Facility closed and the Revolving Credit Facility became available on the May 12, 2016, the closing of the Merger. Borrowings under the Term Loan A Facility and the Revolving Facility will initially bear interest, at the Company’s option, at the adjusted LIBOR rate (subject to a 0.00% floor) plus 2.00% per annum or at the base rate plus 1.00%. Following the delivery of financial statements for the first full fiscal quarter after May 12, 2016, the applicable margin for the borrowings under the Term Loan A Facility and Revolving Facility will range, depending on the Company’s leverage, from 1.50% to 2.25% for LIBOR loans and from 0.50% to 1.25% for base rate loans.

1

The Term Loan A Facility and the Revolving Credit Facility have terms of five years. The Term Loan B Facilities have terms of seven years. The obligations under the New Credit Agreement are guaranteed by certain material domestic subsidiaries of the Company. The term loans and the revolving credit loans may be prepaid in whole or in part at any time without premium or penalty, subject to certain conditions, except that the Term Loan B Facilities require the Company to pay a prepayment fee of 1% on the balance of the loans thereunder if repaid in connection with certain “repricing” transactions on or before April 29, 2017.

Beginning in September 2016, the Company is required to make quarterly principal payments on the Term Loan B Facilities equal to 0.25% of the original principal amount thereof, with the remaining balance due in 2023. Beginning in September 2017, the Company is required to make quarterly principal payment on the Term Loan A Facility equal to 1.25% of the original principal amount thereof, increasing to 1.875% of the original principal amount thereof beginning September 2018, further increasing to 2.50% of the original principal amount thereof beginning September 2019, further increasing to 5% of the original principal amount thereof beginning October 2020, with the remaining balance due in 2021. Subject to certain exceptions and thresholds, the Term Loan A Facility and the Term Loan B Facilities require mandatory prepayments in connection with (i) excess cash flow (with respect to the Term Loan B Facilities only), (ii) non-ordinary course asset sales and other dispositions and (iii) the issuance of certain debt obligations, among other things.

The Revolving Facility is initially subject to a 0.30% per annum commitment fee, subject to step-downs to 0.20% and 0.25% and a step-up to 0.35% based on the Company’s total leverage ratio. In addition, the Company paid a nonrefundable ticking fee of 0.50% per annum on the amount of the aggregate commitments in effect under the Term Loan A Facility and the Revolving Facility from January 7, 2016 until May 12, 2016.

The obligations under the New Credit Agreement are secured on a first-priority basis (subject to permitted liens) by a lien on substantially all the assets and properties of the Company and certain of its material subsidiaries, including all of the capital stock held by such entities (subject to a 65% limitation on pledges of capital stock of foreign subsidiaries and domestic holding companies of foreign subsidiaries), subject to certain exceptions.

The New Credit Agreement requires the Company to comply with a leverage ratio and an interest coverage ratio calculated on a consolidated basis for the Company and its subsidiaries. In addition, the New Credit Agreement contains customary covenants, including covenants that limit or restrict the Company’s and certain of its subsidiaries’ ability to incur liens, incur indebtedness, make certain restricted payments, make acquisitions and investments, loans and guarantees, enter into transactions with affiliates, make certain modifications of organizational documents and certain debt agreements and merge or consolidate, and customary events of default.

On May 12, 2016, a subsidiary of the Company entered into a short-term senior secured bridge facility for $3.0 billion in aggregate principal amount which was repaid on July 21, 2016 (the “Bridge Facility”). Borrowings under the Bridge Facility bore interest at a rate per annum equal to LIBOR plus a margin of 2.00%.

On May 12, 2016, pursuant to the terms of the New Credit Agreement, Western Digital Technologies, Inc., Western Digital Ireland, Ltd. and Western Digital International Ltd. (collectively, the “Existing Borrowers”) repaid all outstanding loans, together with accrued interest and related fees, of approximately $2.2 billion and terminated all commitments under the Company’s previous credit agreement dated January 9, 2014, as amended.

In connection with the Merger, holders of $996 million principal amount of the SanDisk convertible senior notes due 2017 and $1.438 billion of the SanDisk convertible notes due 2020 have exercised their right to settle those notes in exchange for an aggregate of $3.076 billion in cash and approximately 2.3 million shares of Western Digital stock which shares had an aggregate value of approximately $110 million on the date of settlement. In connection with the settlement of these notes, the Company also settled a related portion of its outstanding bond hedge agreements which provided the Company with $470 million of cash and 1.7 million shares of Western Digital Stock which had an aggregate value of $81 million on the date of settlement. The Company also terminated related warrant agreements which were issued in connection with these notes.

The unaudited pro forma condensed combined financial statements have been prepared using the acquisition method of accounting in accordance with ASC 805, “Business Combinations”, with Western Digital treated as the legal and accounting acquirer. The unaudited pro forma condensed combined balance sheet gives effect to the Merger and the Financing Transactions as if those events had occurred on April 1, 2016 while the unaudited pro forma condensed combined statements of income for the year ended July 3, 2015 and for the nine months ended April 1, 2016 each give effect to the Merger and the Financing Transactions as if those events had occurred on June 28, 2014, the first day of Western Digital’s fiscal year ended July 3, 2015. The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial statements to give effect to events that are (i) directly attributable to the Merger and the Financing Transactions, (ii) factually supportable, and (iii) with respect to the statements of income, expected to have a continuing impact on the combined company. The unaudited pro forma condensed combined statements of income do not reflect any non-recurring charges directly related to the Merger and the Financing Transactions that the combined company may have incurred upon completion of the Merger and the Financing Transactions. Further, because the tax rate used for these unaudited pro forma condensed combined financial

2

statements is an estimated statutory tax rate, it will likely vary from the actual effective rate in periods subsequent to the completion of the Merger and the Financing Transactions.

The unaudited pro forma condensed combined financial statements have been prepared for informational purposes only and are not necessarily indicative of what the combined company’s condensed consolidated financial position or results of operations actually would have been had the Merger and the Financing Transactions been completed as of the dates indicated. In addition, the unaudited pro forma condensed combined financial statements do not purport to project the future financial position or operating results of the combined company. The fair value of SanDisk’s identifiable tangible and intangible assets acquired and liabilities assumed are based on preliminary estimates of fair value. As of the date of filing of the Current Report on Form 8-K/A to which the following unaudited pro forma condensed combined financial statements are attached, the Company has not completed the detailed valuation work necessary to finalize the required estimated fair values of the SanDisk assets acquired and liabilities assumed and related allocation of purchase price. The purchase price allocation and related amortization included in the unaudited pro forma condensed combined financial statements are preliminary and have been made solely for purposes of preparing these unaudited pro forma condensed combined financial statements. Management anticipates that the values assigned to the assets acquired and liabilities assumed will be finalized during the one-year measurement period following the date of completion of the Merger. Differences between these preliminary estimates and the final acquisition accounting may occur and these differences could have a material impact on the unaudited pro forma condensed combined financial statements and the combined company’s future results of operations and financial position. In addition, certain reclassifications have been made to SanDisk’s historical financial statements to conform to the presentation used in Western Digital’s historical financial statements. Such reclassifications had no effect on SanDisk’s previously reported financial position or results of operations.

The unaudited pro forma condensed combined financial statements do not include any adjustments for the anticipated benefits from cost savings or synergies of Western Digital and SanDisk operating as a combined company or for liabilities resulting from integration planning, as management is in the process of making these assessments. However, liabilities ultimately may be recorded for severance, relocation or additional retention costs in subsequent periods related to employees of both companies, as well as the costs of vacating certain leased facilities of either company or other costs associated with integrating the companies. The ultimate recognition of such costs and liabilities would affect amounts in the unaudited pro forma condensed combined financial statements, and such costs and liabilities could be material.

The unaudited pro forma condensed combined financial statements should be read in conjunction with the:

• accompanying notes to the unaudited pro forma condensed combined financial statements;

• audited historical consolidated financial statements of Western Digital as of and for the fiscal years ended July 3, 2015, included in Western Digital’s Annual Report on Form 10-K for the fiscal year ended July 3, 2015;

• unaudited historical condensed consolidated financial statements of Western Digital as of and for the nine months ended April 1, 2016 and April 3, 2015, included in Western Digital’s Quarterly Report on Form 10-Q for the fiscal quarter ended April 1, 2016;

• audited historical consolidated financial statements of SanDisk as of and for the fiscal years ended January 3, 2016, included in SanDisk’s Annual Report on Form 10-K for the fiscal year ended January 3, 2016 and this Form 8-K/A;

• unaudited historical condensed consolidated financial statements of SanDisk as of and for the six months ended June 28, 2015 and June 29, 2014, included in SanDisk’s Quarterly Report on Form 10-Q for the fiscal quarter ended June 28, 2015; and

• unaudited historical condensed consolidated financial statements of SanDisk as of and for the three months ended April 3, 2016 and March 29, 2015, included in SanDisk’s Quarterly Report on Form 10-Q for the fiscal quarter ended April 3, 2016 and this Form 8-K/A.

Western Digital and SanDisk have different fiscal year ends which end on the Friday nearest to June 30 and the Sunday closest to December 31, respectively. As a consequence of Western Digital and SanDisk having different fiscal year ends, SanDisk’s historical results have been aligned to more closely conform to the fiscal periods of Western Digital as follows:

• The unaudited pro forma condensed combined balance sheet as of April 1, 2016 combines Western Digital’s unaudited condensed consolidated balance sheet as of April 1, 2016 with SanDisk’s unaudited historical consolidated balance sheet as of April 3, 2016.

• The unaudited pro forma condensed combined statements of income for the fiscal year ended July 3, 2015 combines Western Digital’s historical audited consolidated statement of income for the fiscal year ended July 3,

3

2015 with SanDisk’s historical unaudited condensed consolidated statement of operations for the four fiscal quarters ended June 28, 2015.

• The unaudited pro forma condensed combined statements of income for the nine months ended April 1, 2016 combines Western Digital’s historical unaudited condensed consolidated statement of income for the nine months ended April 1, 2016 with SanDisk’s historical unaudited condensed consolidated statement of operations for the three fiscal quarters ended April 3, 2016.

Western Digital’s historical financial information for the fiscal year ended July 3, 2015 and as of and for the nine-month period ended April 1, 2016 is derived from Western Digital’s Annual Report on Form 10-K and Quarterly Report on 10-Q filed with the U.S. Securities and Exchange Commission (“SEC”) on August 21, 2015 and May 9, 2016, respectively. The historical financial information for SanDisk as of April 3, 2016 is derived from SanDisk’s Quarterly Report on Form 10-Q filed with the SEC on May 2, 2016. The historical financial information for SanDisk for the four fiscal quarters ended June 28, 2015 is derived by adding the historical financial information for SanDisk for the year ended December 28, 2014 included in SanDisk’s Annual Report on Form 10-K filed with the SEC on February 12, 2016 and the historical financial information for SanDisk for the six month period ended June 28, 2015, and subtracting the historical financial information for SanDisk for the six month period ended June 29, 2014, each as included in SanDisk’s Quarterly Report on Form 10-Q filed with the SEC on July 31, 2015. The historical financial information for SanDisk for the three fiscal quarters ended April 3, 2016 is derived by adding the historical financial information for SanDisk for the year ended January 3, 2016 included in SanDisk’s Annual Report on Form 10-K filed with the SEC on February 12, 2016 and the historical financial information for SanDisk for the three-month period ended April 3, 2016 included in SanDisk’s Quarterly Report on Form 10-Q filed with the SEC on May 2, 2016, and subtracting the historical financial information for SanDisk for the six month period ended June 28, 2015 included in SanDisk’s Quarterly Report on Form 10-Q filed with the SEC on July 31, 2015.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Basis of Presentation

The unaudited pro forma condensed combined financial statements are prepared in accordance with Article 11 of SEC Regulation S-X. The historical financial information has been adjusted to give effect to the transactions that are (i) directly attributable to the Merger and the Financing Transactions, (ii) factually supportable and (iii) with respect to the unaudited pro forma condensed combined statements of income, expected to have a continuing impact on the operating results of the combined company. The historical financial information of Western Digital and SanDisk is presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

The acquisition accounting adjustments relating to the Merger are preliminary and subject to change, as additional information becomes available and as additional analyses are performed. There can be no assurances that the final valuations will not result in material changes to this preliminary purchase price allocation. The unaudited pro forma condensed combined financial statements do not give effect to the potential impact of any anticipated benefits from cost savings or synergies that may result from the Merger or to any future integration costs. The unaudited pro forma condensed combined financial statements do not purport to project the future operating results or financial position of the combined company following the Merger and the Financing Transactions.

Certain reclassifications have been made to SanDisk’s historical financial statements to conform to the presentation used in Western Digital’s historical consolidated financial statements. Such reclassifications had no effect on SanDisk’s previously reported financial position or results of operations.

2. Calculation of Purchase Price

Pursuant to the Merger Agreement, Western Digital paid $67.50 in cash and issued 0.2387 shares of its common stock per share of SanDisk common stock. The value of the portion of the per share Merger consideration that was paid in shares of Western Digital common stock was determined based on the closing price of Western Digital common stock on May 12, 2016, the date the Merger was completed. The calculation of purchase price is as follows:

(in millions, except per share amounts)			As of May 12, 2016
Number of Western Digital common shares delivered to SanDisk shareholders
Total number of SanDisk common shares			203
Share exchange ratio			0.2387
Number of Western Digital common shares delivered			49
Purchase price
Cash payment for SanDisk common shares at $67.50 per share			$	13,720
Net cash payment for SanDisk vested stock options outstanding			47
Number of Western Digital common shares delivered	49
Multiplied by market price per share of Western Digital common stock on May 12, 2016	$	36.36
Total value of Western Digital common shares delivered			$	1,764
Value of Western Digital replacement stock options and restricted stock units (1)			57
Total purchase price			$	15,588

(1) Represents the fair value of replacement awards attributable to pre-combination service recorded as part of the consideration transferred in the Merger, while the fair value of replacement awards attributable to post-combination service is recorded separately from the business combination and recognized as compensation expense over the remaining post-combination service period. Under the Merger Agreement, Western Digital assumed all unvested and outstanding SanDisk stock options, all unvested restricted stock units and all vested and outstanding stock options with a per share exercise price that was greater than or equal to the value of the per share Merger consideration at closing held by employees immediately prior to the closing of the Merger. The estimated incremental impact of post-combination compensation cost is not material.

The fair values of Western Digital equivalent restricted stock units and stock options were determined based on the closing market value of Western Digital common stock on May 12, 2016, the day the Merger was completed, and a binomial valuation model utilizing various assumptions, respectively.

3. Preliminary Estimated Purchase Price Allocation

Under the acquisition method of accounting, the total purchase price is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the date of the Merger. The pro forma purchase price allocation below is based on preliminary estimates of fair value as of the Merger closing date of May 12, 2016, and is subject to final management analysis, with the assistance of third party valuation advisors. The preliminary estimated intangible assets primarily consist of developed technology, in-process research and development (“IPR&D”), customer relationships, trade name and trademarks, supply agreements, and backlog. The related estimated useful lives range between one and seven years and are detailed in Note 5(b). The estimated fair values of the intangibles were based primarily on current estimates of SanDisk’s expected future cash flows and may change as estimates and assumptions are refined.

The following table sets forth a preliminary allocation of the purchase price to SanDisk’s identifiable tangible and intangible assets acquired and liabilities assumed by the Company, with the excess recorded as goodwill:

	(in millions)
Cash and cash equivalents	$	3,272
Short-term investments	1,249
Accounts receivable, net	428
Inventories	1,009
Other current assets	254
Property, plant and equipment	946
Notes receivable and investments in Flash Ventures	900
Other non-current assets	176
Identifiable intangible assets	4,956
Total assets	13,190
Accounts payable, accrued expenses and other current liabilities	949
Deferred tax liabilities	662
Other long-term liabilities	179
Convertible debt and related derivatives	3,265
Total liabilities	5,055
Net assets acquired (a)	8,135
Total purchase price (b)	15,588
Estimated goodwill (b) - (a)	$	7,453

Tangible assets acquired and liabilities assumed

The Company has estimated the fair value of tangible assets acquired and liabilities assumed.

Property, plant and equipment, accounts receivable, inventories and deferred revenue have been adjusted to their estimated fair value as discussed further in Note 4 below. The fair value of all other tangible assets acquired and liabilities assumed has been reflected at SanDisk’s book value as of April 3, 2016, which the Company believes to be a reasonable approximation of fair value.

Identifiable intangible assets

Preliminary identifiable intangible assets in the pro forma financial information consist of anticipated intangibles derived from developed technology, IPR&D, customer relationships, trade name and trademarks, supply agreements, and backlog. The amortization related to these identifiable intangible assets is reflected as a pro forma adjustment in the unaudited pro forma condensed combined statements of income, as further described in Note 5(b). The estimated fair values of the identifiable intangible assets and related amortization are preliminary and are based on management’s estimates after consideration of similar transactions. As discussed above, the amount that will ultimately be allocated to identifiable intangible assets, and the related amount of amortization, may differ materially from this preliminary allocation. Therefore, the amount of amortization following the Merger may differ significantly between periods based upon the final value assigned and timing of when IPR&D is placed in service and used for each identifiable intangible asset.

Identifiable intangible assets recognized in the Merger are not expected to be deductible for tax purposes. Adjustments were made to record deferred taxes related to taxable temporary differences arising from a difference between the tax basis and the recognized value of identifiable intangible assets assumed in the Merger. These adjustments are based on estimates of the fair value of SanDisk’s assets to be acquired, the liabilities to be assumed and the related allocations of purchase price. These

preliminary estimates are subject to further review by the Company’s management, which may result in material adjustments to deferred taxes with an offsetting adjustment to goodwill.

Goodwill represents the excess of the purchase price over the fair value of the underlying net assets acquired. Goodwill is not amortized but instead is reviewed for impairment at least annually, absent any indicators of impairment. Goodwill is attributable to planned growth in new markets, and synergies expected to be achieved from the combined operations of Western Digital and SanDisk. Goodwill recognized in the Merger is not expected to be deductible for tax purposes.
