    For the fiscal year, net revenue, gross profit and operating
profit all reached record levels. Net revenue grew 64% in fiscal 2006
to $148.7 million from $90.6 million in fiscal 2005. Gross profit
climbed 51% to $114.6 million compared to $75.9 million in fiscal
2005. Operating income rose 155% to $24.0 million, from $9.4 million
in fiscal 2005. Net income for fiscal 2006 was a record $19.3 million
or $0.70 per diluted share versus $8.5 million or $0.32 per diluted
share in fiscal 2005.
    For the quarter, net revenue was $40.4 million, reflecting an
increase of more than 13% from $35.6 million for the fourth quarter of
fiscal 2005. Gross profit was $32.7 million compared to $27.8 million
for the fourth quarter of fiscal 2005, representing an increase of
18%. Operating income was $9.3 million or 23% of revenue compared to
$2.1 million or 6% of revenue for the fourth quarter of fiscal 2005.
Net income was $2.1 million or $0.08 per share in the fourth quarter
of fiscal 2006 including an unusually high provision for income taxes.
The non-GAAP presentation below is calculated based upon the same
effective income tax rate (7.4%) as we used in our fiscal fourth
quarter guidance. As a result, non-GAAP net income for the quarter was
$8.5 million and net income per diluted share on a non-GAAP basis was
$0.31.
    Dave Habiger, President and Chief Executive Officer of Sonic,
stated, "We are very pleased with the Company's performance this
quarter and for the fiscal year, as we met or exceeded all of our
operating goals. We expanded our technology and OEM partnerships,
which continued to drive all areas of our business. As new formats and
channels such as HD and download and burn, emerge and develop, we
believe Sonic is well positioned to continue to lead the market for
digital media software."

    Non-GAAP Presentation

    In this press release, Sonic provides an adjustment to financial
information calculated on the basis of GAAP as supplemental
information relating to its results of operations. These non-GAAP
financial measures are used in addition to and in conjunction with
results presented in accordance with GAAP, and are intended to provide
additional insight into our operations that, when viewed with our GAAP
results and the accompanying reconciliations to corresponding GAAP
financial measures, offer a more complete understanding of factors and
trends affecting our business. These non-GAAP measures should be
considered as a supplement to, and not as a substitute for or superior
to, the corresponding measures calculated in accordance with GAAP. The
non-GAAP disclosures and the non-GAAP adjustments, including the basis
for such adjustments and the impact on our operations, are outlined
below:
    Tax Adjustment. In our non-GAAP presentation, we have shown our
net income calculated based upon the same effective income tax rate
(7.4%) as we used in our fourth quarter guidance. As we have
previously noted and due to our recent history of profitability, Sonic
is in the process of transitioning from a company with substantial
valuation allowances on its deferred tax assets and a low effective
tax rate to a company with substantially reduced valuation allowances
and an effective tax rate close to statutory rates. Over the past year
and during this transition period, Sonic has experienced fluctuations
in its effective tax rate based upon changes in its net value of
deferred tax assets that it has accumulated over time. We believe that
these fluctuations are not indicative of the overall fundamentals of
our business and that they may have a disproportionate impact on our
operating results for the fourth quarter of fiscal 2006. In this case,
due to these transitional fluctuations and the results of a phase I
study of the estimated value of our deferred research tax credits
accumulated over time, our effective tax rate in March 2006 was 77.2%
rather than the 7.4% rate that we experienced in the third quarter and
that was the basis for our fourth quarter earnings per share ("EPS")
guidance.
    Accordingly, and as set forth in more detail in the reconciliation
table below, we have provided a non-GAAP fully diluted EPS that
adjusts for the difference between the two rates. Although we do not
anticipate that the 7.4% will continue to be indicative of our tax
rate in the future, we believe our non-GAAP presentation provides
important and useful information to investors, as it enables them to
reconcile our results based upon our actual tax rate to those
forecasted based upon tax rate assumptions per our prior guidance. In
the absence of such information, we believe that investors may find it
difficult to evaluate our fiscal fourth quarter results apart from the
tax impact or compare them to our results in prior periods. We have
used this non-GAAP measure internally in order to evaluate the
operating results of our business on a consistent basis and to measure
our performance of business goals that we establish in advance. The
economic substance behind our decision to use this non-GAAP measure is
an increase of $0.23 per fully diluted share over the comparable GAAP
measure. Material limitations associated with the use of this measure
versus the comparable GAAP EPS measure are (a) the non-GAAP measure
provides a view of our earnings that does not include all of our tax
obligations for the period in question, and (b) this may not enhance
the comparability of our results to those of other companies
undergoing similar tax rate transitions. We compensate for these
limitations, by providing full disclosure of the effects of this
non-GAAP measure, by presenting the corresponding treatment prepared
in conformity with GAAP in this release and in our financial
statements and by providing a reconciliation to the corresponding GAAP
measure so that investors can use the information to perform their own
analysis.
    Sonic will conduct a conference call at 1:30 p.m. PDT, or 4:30
p.m. EDT, today to discuss its financial results for the fourth
