Item 2.02 Results of Operations and Financial Condition

On January 27, 2016, SanDisk Corporation (the “Registrant” or “SanDisk”) issued a press release to report its financial results for its fourth quarter and fiscal year ended January 3, 2016.

The press release and accompanying Prepared Remarks for Investors are attached hereto as Exhibit 99.1 and Exhibit 99.2, respectively, and are incorporated herein in their entirety by reference. In addition to the preliminary condensed consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP), the attached documents contain non-GAAP measures of operating results, net income and net income per share, which are adjusted from results based on GAAP to exclude certain expenses, gains and losses. These non-GAAP financial measures are provided to enhance the user’s overall understanding of the Registrant’s current financial performance and its prospects for the future. Specifically, the Registrant believes the non-GAAP results provide useful information to both management and investors as these non-GAAP results exclude certain expenses, gains and losses that it believes are not indicative of its core operating results and because they are consistent with the financial models and estimates published by many analysts who follow the Registrant. For example, because the non-GAAP results exclude the expenses the Registrant recorded for share-based compensation, amortization of acquisition-related intangible assets related to acquisitions of Pliant Technology, Inc. in May 2011, FlashSoft Corporation in February 2012, Schooner Information Technology, Inc. in June 2012, SMART Storage Systems in August 2013 and Fusion-io, Inc. in July 2014, inventory step-up expense, impairment of acquisition-related in-process research and development intangible assets, Western Digital Corporation (“Western Digital”) acquisition-related expenses, gains and losses related to the shortened duration or liquidation prior to their effective maturity of marketable securities due to the pending acquisition of the Registrant by Western Digital, non-cash economic interest expense associated with the Registrant’s convertible senior notes, non-cash change in fair value of the liability component of the convertible senior notes due to the conversion of a portion of the 1.5% Convertible Senior Notes due 2017 and related tax adjustments, the Registrant believes the inclusion of non-GAAP financial measures provides consistency in its financial reporting. In addition, the Registrant’s non-GAAP diluted shares are adjusted for the impact of expensing share-based compensation and include the impact of the Registrant’s call optionswhich, when exercised, will offset the issuance of dilutive shares from the Registrant’s convertible senior notes, while the Registrant’s GAAP diluted shares exclude the anti-dilutive impact ofthese call options. These non-GAAP results are some of the primary indicators management uses for assessing the Registrant’s performance, allocating resources, and planning and forecasting future periods. Further, management uses non-GAAP information that excludes certain charges, such as share-based compensation, amortization of acquisition-related intangible assets, inventory step-up expense, impairment of acquisition-related in-process research and development intangible assets, Western Digital acquisition-related expenses, gains and losses related to the shortened duration or liquidation prior to their effective maturity of marketable securities due to the pending acquisition of the Registrant by Western Digital, non-cash economic interest expense associated with the convertible senior notes, non-cash change in fair value of the liability component of the convertible senior notes due to the conversion of a portion of the 1.5% Convertible Senior Notes due 2017 and related tax adjustments, as these non-GAAP charges do not reflect the cash operating results of the business or the ongoing results. These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. These non-GAAP measures may be different than the non-GAAP measures used by other companies.

The information contained herein and in the accompanying exhibits shall not be incorporated by reference into any filing of the Registrant, whether made before or after the date hereof, regardless of any general incorporation language in such filing, unless expressly incorporated by specific reference in such filing.

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 preliminary 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 on December 11, 2015, as amended by Amendment No.1 filed with the SEC on January 27, 2016.  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 December 28, 2014, 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.
