REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders of
SanDisk Corporation
We have audited SanDisk Corporation’s internal control over financial reporting as of December 28,
2014, based on criteria established in Internal Control — Integrated Framework issued by the Committee
of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). SanDisk
Corporation’s management is responsible for maintaining effective internal control over financial
reporting, and for its assessment of the effectiveness of internal control over financial reporting included in
the accompanying Report of Management on Internal Control Over Financial Reporting. Our
responsibility is to express an opinion on the company’s internal control over financial reporting based on
our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in
all material respects. Our audit included obtaining an understanding of internal control over financial
reporting, assessing the risk that a material weakness exists, testing and evaluating the design and
operating effectiveness of internal control based on the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We believe that our audit provides a
reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with generally accepted accounting principles. A company’s internal
control over financial reporting includes those policies and procedures that (1) pertain to the maintenance
of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted accounting principles,
and that receipts and expenditures of the company are being made only in accordance with authorizations
of management and directors of the company; and (3) provide reasonable assurance regarding prevention
or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have
a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.
In our opinion, SanDisk Corporation maintained, in all material respects, effective internal control
over financial reporting as of December 28, 2014, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), the Consolidated Balance Sheets of SanDisk Corporation as of December 28, 2014
and December 29, 2013, and the related Consolidated Statements of Operations, Comprehensive Income,
Equity, and Cash Flows for each of the three years in the period ended December 28, 2014 and our report
dated February 10, 2015 expressed an unqualified opinion thereon.
