Coughlin Stoia Geller Rudman & Robbins LLP Files Class Action Suit against SiRF Technology Holdings, Inc.

SAN DIEGO--(Business Wire)--
Coughlin Stoia Geller Rudman & Robbins LLP ("Coughlin Stoia")
(http://www.csgrr.com/cases/sirf/) today announced that a class action
has been commenced in the United States District Court for the
Northern District of California on behalf of purchasers of SiRF
Technology Holdings, Inc. ("SiRF") (NASDAQ:SIRF) publicly traded
securities during the period between October 30, 2007 and February 4,
2008 (the "Class Period").

If you wish to serve as lead plaintiff, you must move the Court no
later than 60 days from today. If you wish to discuss this action or
have any questions concerning this notice or your rights or interests,
please contact plaintiff's counsel, Darren Robbins of Coughlin Stoia
at 800/449-4900 or 619/231-1058, or via e-mail at djr@csgrr.com. If
you are a member of this class, you can view a copy of the complaint
as filed or join this class action online at

may move the Court to serve as lead plaintiff through counsel of their
choice, or may choose to do nothing and remain an absent class member.

The complaint charges SiRF and certain of its officers and
directors with violations of the Securities Exchange Act of 1934.
SiRF, through its subsidiaries, engages in the development and
marketing of semiconductor and software products that are designed to
enable location-awareness utilizing global positioning system and
other location technologies worldwide.

The complaint alleges that during the Class Period, defendants
issued materially false and misleading statements regarding the
Company's business and prospects. As a result of defendants' false
statements, SiRF stock traded at artificially inflated prices during
the Class Period, permitting one of the defendants to sell $9.6
million worth of his SiRF stock at $24.18-$24.29 per share.

On February 4, 2008, after the market closed, the Company
announced disappointing financial results for its fourth quarter and
fiscal 2007. On February 5, 2008, SiRF's stock collapsed $8.91 per
share to close at $7.36 per share, a one-day decline of 54%.

According to the complaint, the true facts, which were known by
the defendants but concealed from the investing public during the
Class Period, were as follows: (a) SiRF's acquisition of Centrality
Communications, Inc. was having an adverse impact on SiRF's results
due to the similar products sold by Centrality which were
cannibalizing SiRF's sales; (b) SiRF's major customers were not
placing orders at sufficient quantities for SiRF to meet the
aggressive targets set by and for the Company; (c) Centrality's
System-on-Chip ("SoC") product line had lower gross margins than
SiRF's products and defendants knew that although the Centrality
acquisition would increase revenues in the fourth quarter (as it did),
it would also significantly lower SiRF's gross margins (as it also
did); (d) competitive pressures were having much more of an adverse
impact on the Company than acknowledged by defendants, as SiRF's
customers were moving to cellular-enabled products which SiRF could
not adequately compete with; (e) as of October 30, 2007, one month
into the fourth quarter, fourth quarter gross margins would be down
significantly because of the lower SoC product line margins; and (f)
downward pricing pressures were accelerating and would lead to lower
margins and earnings in future quarters.

Plaintiff seeks to recover damages on behalf of all purchasers of
SiRF publicly traded securities during the Class Period (the "Class").
The plaintiff is represented by Coughlin Stoia, which has expertise in
prosecuting investor class actions and extensive experience in actions
