              Sonic Solutions Updates Financial Guidance

    NOVATO, Calif.--(BUSINESS WIRE)--Feb. 8, 2006--Sonic Solutions(R)
(NASDAQ:SNIC) management provided updated financial guidance during
its fiscal third quarter 2006 earnings conference call today.
    For the Fiscal Year ending March 31, 2007, Company management
expects, consistent with previous guidance, that revenues will grow on
a year-over-year basis by between 20% to 25%, and that Sonic will
continue to be significantly profitable with a target operating margin
between 25% and 30% of revenues. Management stated that the Company
should continue to exhibit a pronounced seasonal revenue pattern, with
the June and September quarters relatively lighter versus the December
and March quarters.
    For the quarter that will end on March 31, 2006, management
expects revenues and earnings to be roughly equal to the revenue and
earnings results that the Company reported for the quarter ending
December 31, 2005.
    All guidance numbers are based upon U.S. generally accepted
accounting principles.
