Exhibit 99.1



                   Sonic Solutions Updates Financial Guidance


     NOVATO, Calif.--(BUSINESS WIRE)--May 23, 2006--Sonic Solutions(R)
(NASDAQ:SNIC) management provided updated financial guidance during its fourth
quarter fiscal 2006 earnings conference call today.
     Consistent with previous guidance, Sonic's management expects net revenue
to grow 20% to 25% for fiscal 2007, and that Sonic will continue to target
operating margins of 25% to 30% of net revenue. As management has discussed, the
Company should continue to exhibit a pronounced seasonal revenue pattern, with
the June and September quarters relatively lighter than the December and March
quarters.
     For the first fiscal quarter ending June 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 $0.13 and $0.16. Effective as of
April 1, 2006, the Company adopted Statement of Financial Accounting Standard
No. 123R ("SFAS 123R") "Share-Based Payments." The non-GAAP earnings per share
forecast for the quarter ending June 30, 2006 excludes the impact of the stock
option expense pursuant to SFAS 123R to be recorded in the income statement,
which the Company forecasts will be approximately $750,000 or $0.02 per fully
diluted share. Given the significance and non-cash nature of this expense,
management has excluded such expense from the non-GAAP earnings per share
guidance.

     About Non-GAAP Financial Measures

     To supplement the Company's updated financial guidance for the first
quarter ending June 30, 2006, management is providing high and low forecasts of
non-GAAP fully diluted earnings per share. The Company's management does not
itself, nor does it suggest that investors should, consider such non-GAAP
financial measure in isolation from, or as a substitute for, 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 equity-based compensation expenses relating to SFAS 123R that
management does not consider meaningful for purposes of analyzing the Company's
core operating results and making budget-planning decisions. In addition, the
Company's financial results for the first quarter of fiscal 2006 did not include
non-cash equity-based compensation expenses; therefore the non-GAAP presentation
facilitates comparison of the Company's projections for the first quarter of
fiscal 2007 and the operating results for the first quarter of fiscal 2006. The
Company believes this non-GAAP financial measure 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 this non-GAAP measure internally to plan and forecast
future periods, to establish operational goals, to compare with its business
plan and individual operating budgets on a consistent basis and to allocate
resources. The economic substance behind the decision to use this non-GAAP
measure is an increase of $0.02 per fully diluted share over the comparable GAAP
measure. Material limitations associated with the use of this measure versus the
comparable GAAP measure include the fact that the Company's competitors may not
use the same non-GAAP financial measures. Management compensates for these
limitations by providing full disclosure of the effects of this non-GAAP
measure, by presenting the corresponding GAAP financial measure in this release
and in the Company's financial statements and by providing a reconciliation to
the corresponding GAAP measure to enable investors to perform their own
analysis.

non-GAAP earnings per share
