Murray, Frank & Sailer LLP Files Class Action Lawsuit Against SunPower Corporation

NEW YORK--(Business Wire)--
Murray, Frank & Sailer LLP has filed a class action Complaint in the United
States District Court for the Northern District of California on behalf of a
class consisting of all persons or entities who purchased the securities of
SunPower Corporation ("SunPower" or the "Company") (Nasdaq:SPWRA; SPWRB) between
April 17, 2008 and November 16, 2009, inclusive (the "Class Period").

The Complaint charges SunPower and certain of the Company`s executive officers
with violations of federal securities laws. SunPower designs, manufactures and
delivers high-performance solar electric systems worldwide for residential,
commercial and utility-scale power plant customers. The Complaint alleges that
throughout the Class Period defendants knew or recklessly disregarded that their
public statements concerning SunPower`s financial performance were materially
false and misleading. Specifically, defendants made false and/or misleading
statements and/or failed to disclose: (1) that the Company made unsubstantiated
accounting entries during the Class Period; (2) that, as a result, the Company`s
financial results were overstated during the Class Period; (3) that the
Company`s financial results were not prepared in accordance with Generally
Accepted Accounting Principles ("GAAP"); (4) that the Company lacked adequate
internal and financial controls; and (5), as a result of the above, the
Company`s financial statements were materially false and misleading at all
relevant times.

On November 16, 2009, SunPower shocked investors when it announced an internal
investigation by its Audit Committee of certain unsubstantiated accounting
entries related to cost of goods sold in the Company`s Philippines operations.
SunPower disclosed that the Company`s Audit Committee concluded that the
Company`s previously issued interim financial statements for each of the 2009
quarterly periods, the previously reported financial results for the fiscal year
ending December 28, 2008, the financial information in its quarterly reports on
Form 10-Q for the 2009 quarters, the financial information in the 2008 annual
report on Form 10-K, and the guidance provided by the Company for the 2009
fiscal year, should no longer be relied upon.

On this news, shares of SunPower`s Class A common stock declined $5.04 per
share, or approximately 18.51%, to close on November 17, 2009, at $22.19 per
share, on heavy volume, and shares of SunPower`s Class B common stock declined
$4.43 per share, approximately 18.54%, to close on November 17, 2009, at $19.47
per share, on heavy volume.

Plaintiff seeks to recover damages on behalf of class members and is represented
by Murray, Frank & Sailer LLP, a law firm with extensive experience in
prosecuting shareholder lawsuits.

If you are a member of the class described above, you may move the Court, not
later than January 19, 2010, to serve as Lead Plaintiff for the class. A Lead
Plaintiff is a representative chosen by the Court who acts on behalf of other
class members in directing the litigation. You do not need to be a Lead
Plaintiff to be included in the class. If you purchased SunPower Securities and
wish to discuss this litigation, or have any questions concerning this Notice or
your rights or interests with respect to these matters, please contact us.
