    NOVATO, Calif.--(BUSINESS WIRE)--Feb. 15, 2007--Sonic Solutions(R)
(NASDAQ:SNIC) today announced the following selected preliminary
unaudited financial results for the quarter ended December 31, 2006.

    Selected Preliminary Financial Results

    Net revenue for the quarter was $39,120,000. Cost of revenue,
excluding any stock based compensation costs, was $8,838,000. Included
in cost of revenue is $1,236,000 of expense related to the
amortization of acquired intangibles. Marketing and sales expenses,
excluding any stock based compensation costs, were $8,003,000.
Research and development expenses, excluding any stock based
compensation costs, were $10,875,000. General and administrative
expenses, excluding any stock based compensation costs, were
$4,788,000. Sonic recorded a $3,400,000 charge for acquired in-process
research and development, on a preliminary basis, related to the
November 2006 acquisition of System OK AB, a private Swedish software
concern. Other income (net of other expenses) was $311,000. For the
quarter ended December 31, 2006, the number of shares outstanding on a
fully diluted basis was approximately 27,500,000.

    As of December 31, 2006, Sonic had cash and cash equivalents of
$22,543,000 and short term investments of $33,450,000. Bank debt at
December 31, 2006 was $20,000,000. During the quarter and as part of
the acquisition of System OK, Sonic paid $7,920,000 to System OK's
shareholders.

    Guidance

    In addition, Sonic announced the following guidance:

    For the fourth fiscal quarter ending March 31, 2007, management
anticipates net revenue, on a GAAP basis, will be between $37 million
and $41 million. Cost of revenue, as a percentage of net revenue and
excluding expenses related to the amortization of intangibles and
stock based compensation, is estimated to be 18%. Operating expenses,
excluding stock based compensation and any costs associated with
Sonic's options review, are estimated to be $24 million. Other income
(net of other expenses) is estimated to be $350,000. The number of
shares outstanding on a fully diluted basis is estimated to be 27.5
million.

    For Sonic's Roxio Division, during fiscal year 2008, management
expects net revenue in the bricks and mortar retail business channel
to be roughly flat compared to fiscal 2007, OEM business channel net
revenue to grow by 10-15%, and direct online sales growth of more than
25%. Sonic's management further expects Advanced Technology Group
revenues to grow by more than 25% over fiscal 2007. Sonic will
forecast relatively flat revenue for its Professional Products Group
until the Company sees clear evidence of Hollywood's commitment to
volume title production in high-definition formats.

    Options Review

    The Company's selected preliminary results and guidance may be
adjusted as a result of possible restatement of historical results. As
previously announced on February 1, 2007, Sonic has commenced a
voluntary review of its historical and current stock option grant
practices and related accounting. Based on the review, the audit
committee and Sonic management have preliminarily concluded that,
under applicable accounting guidance, Sonic lacks sufficient
documentation for certain historical option grants and that the
measurement dates associated with these option grants will need to be
adjusted. Further, as previously announced, the audit committee, after
consultation with management and the Company's board of directors, has
determined that the Company's annual and interim financial statements
may no longer be relied upon.

    Sonic believes it will have to record additional non-cash charges
for stock-based compensation expense and restate previous financial
statements, and that such charges will be material. Sonic is not yet
able to determine the amount of such charges or the resulting tax and
accounting impact of these actions. Sonic intends to file its restated
financial results and related periodic reports as quickly as possible.

    All results and guidance reported today are presented without
taking into account any adjustments to either current or previously
reported results that may be required in connection with any
restatement and should be considered preliminary until Sonic files its
quarterly report on Form 10-Q for the third quarter ended December 31,
2006 and any required amended historical financial statements.
Investors are cautioned that Sonic is unable to provide
reconciliations to corresponding U.S. Generally Accepted Accounting
Principles ("GAAP") measures for the non-GAAP information provided in
this press release due to the ongoing options practice and accounting
review. The non-GAAP information includes those measures that exclude
stock based compensation costs and/or other expenses that would
otherwise be included in the applicable GAAP measures.

    Sonic will conduct a conference call at 1:30 p.m. PST, or 4:30
p.m. EST, today to discuss its preliminary financial results for the
third quarter ended December 31, 2006. Investors are invited to listen
to Sonic's quarterly conference call on the investor section of
Sonic's website at www.sonic.com. A replay of the web cast will be
available approximately two hours after the conclusion of the call. An
audio replay of the conference call will also be made available

replay will remain available until 9:00 PM PST, midnight EST, February
22, 2007, and can be accessed by dialing 719-457-0820 or 888-203-1112
and entering confirmation code 9663492.
