Item 8.01. Other Events.

On February 23, 2016, Western Digital Corporation, a Delaware corporation (“Western Digital”) issued a press release (i) reaffirming its commitment to its acquisition of SanDisk Corporation (the “Company” or “SanDisk”) and (ii) announcing the termination by Unis Union Information System Ltd., a Hong Kong corporation (“Unis Union”), of the Stock Purchase Agreement, dated September 29, 2015 (the “Unis Investment”), by and among Western Digital, Unis Union and Unisplendour Corporation Limited, a Chinese corporation. Under the terms of the Agreement and Plan of Merger, dated October 21, 2015 (the “Merger Agreement”), by and among SanDisk, Western Digital and Schrader Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of Western Digital, because the Unis Investment has been terminated, the consideration to be paid to SanDisk stockholders per share of SanDisk common stock, at the closing of the transaction, will consist of $67.50 in cash and 0.2387 shares of Western Digital common stock, subject to the terms of the Merger Agreement. Western Digital and the Company have already received regulatory approval from the U.S., European Union, Singapore, Japan, Taiwan, South Korea and Turkey. Closing of the transaction remains subject to the receipt of required regulatory approvals from China and South Africa, approval of Western Digital and Company stockholders, and other customary closing conditions.

Forward-Looking Statements

All statements included or incorporated by reference in this document, other than statements or characterizations of historical fact, are forward-looking statements within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based on SanDisk’s current expectations, estimates and projections about its business and industry, management’s beliefs, and certain assumptions made by SanDisk and Western Digital, all of which are subject to change. Forward-looking statements can often be identified by words such as “anticipates,” “expects,” “intends,” “plans,” “predicts,” “believes,” “seeks,” “estimates,” “may,” “will,” “should,” “would,” “could,” “potential,” “continue,” “ongoing,” similar expressions, and variations or negatives of these words. Examples of such forward-looking statements include, but are not limited to, references to the anticipated benefits of the proposed merger and the expected date of closing of the merger with Western Digital’s wholly-owned subsidiary, Schrader Acquisition Corporation. These forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially and adversely from those expressed in any forward-looking statement.

Important risk factors that may cause such a difference in connection with the proposed merger include, but are not limited to, the following factors: (1) the inability to complete the merger due to the failure to obtain stockholder approval for the merger or the failure to satisfy other conditions to completion of the merger, including the receipt of all regulatory approvals related to the merger; (2) uncertainties as to the timing of the consummation of the merger and the ability of each party to consummate the merger; (3) risks that the proposed merger disrupts the current plans and operations of Western Digital or SanDisk; (4) the ability of Western Digital and SanDisk to retain and hire key personnel; (5) competitive responses to the proposed merger; (6) unexpected costs, charges or expenses resulting from the merger; (7) the outcome of any legal proceedings that could be instituted against Western Digital, SanDisk or their respective directors related to the merger agreement; (8) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the merger; (9) the inability to obtain, or delays in obtaining, cost savings and synergies from the merger; (10) delays, challenges and expenses associated with integrating the combined companies’ existing businesses and the indebtedness planned to be incurred in connection with the merger; and (11) legislative, regulatory and economic developments. These risks, as well as other risks associated with the proposed merger, are more fully discussed in the joint proxy statement/prospectus that is included in the Registration Statement on Form S-4 filed with the Securities and Exchange Commission (“SEC”) in connection with the proposed merger. The forward-looking statements in this document speak only as of the date of the particular statement. Neither SanDisk nor Western Digital undertakes any obligation to revise or update publicly any forward-looking statement to reflect future events or circumstances.

In addition, actual results are subject to other risks and uncertainties that relate more broadly to SanDisk’s overall business, including those more fully described in SanDisk’s filings with the SEC including its annual report on Form 10-K for the fiscal year ended January 3, 2016, and its quarterly reports filed on Form 10-Q for fiscal year 2015, and Western Digital’s overall business and financial condition, including those more fully described in Western Digital’s filings with the SEC including its annual report on Form 10-K for the fiscal year ended July 3, 2015 and its quarterly reports filed on Form 10-Q for the current fiscal year.
