              Sonic Solutions Updates Financial Guidance

    NOVATO, Calif.--(BUSINESS WIRE)--Aug. 8, 2006--Sonic Solutions(R)
(NASDAQ:SNIC) management provided updated financial guidance during
its first quarter ended June 30, 2006 earnings conference call today.
    For the second fiscal quarter ending September 30, 2006,
management anticipates net revenue, on a GAAP basis, will be between
$36 million and $38 million; fully diluted earnings per share will be
between $0.11 and $0.14; and non-GAAP fully diluted earnings per share
will be between $0.14 and $0.17. As of April 1, 2006, Sonic adopted
Statement of Financial Accounting Standard No. 123R ("SFAS 123R")
"Share-Based Payments." The non-GAAP earnings per share forecast for
the quarter ending September 30, 2006 excludes the impact of the stock
option expense pursuant to SFAS 123R and the amortization of acquired
intangibles expense to be recorded in the income statement, which
Sonic forecasts will be approximately $0.02 and $0.04 per fully
diluted share, respectively, before being adjusted for income taxes.
Given the significance and non-cash nature of these expenses, and for
the reasons set forth below, management has excluded such expenses
from the non-GAAP earnings per share guidance.

    About Non-GAAP Financial Measures

    To supplement Sonic's updated financial guidance for the second
quarter ending September 30, 2006, management is providing high and
low forecasts of non-GAAP fully diluted earnings per share. Management
does not itself, nor does it suggest that investors should, consider
such non-GAAP financial measures in isolation from, or as a substitute
for or superior to, financial information prepared and presented in
accordance with GAAP. Management believes the non-GAAP presentation is
useful to investors because such presentation excludes non-cash
expenses of equity-based compensation relating to SFAS 123R and
amortization on acquired intangibles, which offers investors a better
understanding of Sonic's core operating results and budget-planning
decisions. The amortization expense on acquired intangibles does not
result in ongoing cash expenditures and, in management's view, does
not otherwise have a material impact on Sonic's ongoing operations. In
addition, Sonic's financial results for the second quarter ended
September 30, 2005 did not include non-cash equity-based compensation
expenses; therefore the exclusion of non-cash expenses of equity-based
compensation facilitates comparison of Sonic's projections for the
second quarter ending September 30, 2006 and the operating results for
the second quarter ended September 30, 2005. Sonic further believes
this non-GAAP presentation is useful to investors in allowing for
greater transparency with respect to supplemental information used by
management in its financial and operational decision making.
    Management uses these non-GAAP measures internally to plan and
forecast future periods, to establish operational goals, to compare
with its business plan and individual operating budgets and to
allocate resources. The economic substance behind the decision to use
these non-GAAP measures is an increase of approximately $0.03, tax
adjusted, per fully diluted share over the comparable GAAP measures.
Material limitations associated with the use of these measures versus
the comparable GAAP measures include the fact that our competitors,
who each have their own unique operating and acquisition history, may
address the impact of acquisitions and adoption of SFAS 123R
differently. Management compensates for these limitations by providing
full disclosure of the effects of the non-GAAP measures, by presenting
the corresponding GAAP financial measures in this release and in
Sonic's financial statements and by providing a reconciliation to the
corresponding GAAP measures to enable investors to perform their own
analysis.
