    Sonic Solutions Reports Selected Preliminary Financial Results
      for Fourth Quarter Ended March 31, 2007; Updates Guidance


    NOVATO, Calif.--(BUSINESS WIRE)--May 17, 2007--Sonic Solutions(R)
(NASDAQ:SNIC) today announced the following selected preliminary
unaudited financial results for the fourth quarter ended March 31,
2007.

    Selected Preliminary Financial Results

    Net revenue for the quarter was $38.1 million. Cost of revenue,
excluding any stock-based compensation costs, was $9.0 million.
Included in cost of revenue is $1.4 million of expense related to the
amortization of acquired intangibles. Marketing and sales expenses,
excluding any stock-based compensation costs, were $8.6 million.
Research and development expenses, excluding any stock-based
compensation costs, were $11.7 million. General and administrative
expenses, excluding any stock-based compensation costs, were $4.9
million, of which $0.6 million represented legal and professional
expenses associated with the stock option review. Other income (net of
other expenses) was $0.2 million. For the quarter ended March 31,
2007, the number of shares outstanding on a fully diluted basis was
approximately 27.5 million.

    As of March 31, 2007, Sonic had cash and cash equivalents of $17.1
million and short term investments of $47.3 million. Bank debt at
March 31, 2007 was $20.0 million.

    Guidance

    For the first fiscal quarter ending June 30, 2007, the Company's
management anticipates net revenue, on a GAAP basis, will be between
$33 million and $35 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 19%.
Operating expenses, excluding stock-based compensation costs and any
one-time charges associated with the Company's option review, are
estimated to be $25 million.

    Options Review

    The Company's selected preliminary results and guidance may be
adjusted as a result of the expected 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 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 cash and 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
annual report on Form 10-K for the fiscal year ended March 31, 2007,
its quarterly report on Form 10-Q for the third quarter ended December
31, 2006, and any required restatement of 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.

    Continued Nasdaq Listing

    As previously announced, on April 23, 2007, the Company received a
letter from a Nasdaq Listing Qualifications Panel (the "Panel")
notifying the Company that the Panel had granted the Company's request
for continued listing of its securities on the Nasdaq Global Select
Market. The Company's continued listing is subject to certain
conditions, including: (1) on or before June 20, 2007, the Company
must file its Form 10-Q for the quarter ended December 31, 2006, as
well as any required restatements; (2) on or before July 23, 2007, the
Company must hold its 2006 annual shareholder meeting; and (3) the
Company must provide Nasdaq with additional information regarding the
Company's previously announced voluntary review of its historical and
current stock option grant practices and related accounting. The
Company is currently unable to determine if it will be able to satisfy
the conditions specified by the Panel by their respective deadlines.
Should the Company be unable to meet the conditions set forth in the
Panel's decision, there can be no assurance that Nasdaq will grant an
additional extension of time or that the Company's securities will
continue to be listed on The Nasdaq Stock Market.
