Dolby Laboratories Reports Record Revenue for Second Quarter of Fiscal 2005;
Company Issues Full-Year Guidance

    SAN FRANCISCO--(BUSINESS WIRE)--May 5, 2005--In its first earnings
report as a public company, Dolby Laboratories (NYSE:DLB) today
announced the Company's financial results for the second quarter of
fiscal 2005 ended April 1, 2005. For the second quarter, Dolby
reported total revenue of $85.1 million, the highest quarterly revenue
in its 40-year history, compared to $78.7 million for the second
quarter of fiscal 2004. Second-quarter net income was $10.3 million,
or $0.10 per diluted share compared to $12.4 million, or $0.14 per
diluted share for the second quarter of fiscal 2004. Per-share
calculations are based on 105.5 million diluted shares in the second
quarter of fiscal 2005 compared with 91.0 million diluted shares in
the comparable year-ago quarter as a result of the Company's IPO in
February 2005.
    "We are very pleased with this quarter's results. Revenue was at a
record quarterly level, driven by continued growth in licensees' sales
of DVD-related products," said Bill Jasper, Dolby Laboratories'
President and Chief Executive Officer. "During the second quarter we
continued to make significant investments in our infrastructure to
support anticipated growth and to meet the needs of being a public
company. We also remain focused on the future through research and
development as we strive to bring new high-quality entertainment
technologies to the market."
    On a pro forma basis, second-quarter net income was $14.9 million,
or $0.14 per diluted share, compared to $18.5 million, or $0.20 per
diluted share last year. Pro forma results exclude the effect of
royalties payable to the Company's founder for the use of intellectual
property rights under licensing agreements, which discontinued as of
February 2005. These amounts were $7.7 million and $10.0 million in
the second quarter of fiscal 2005 and 2004, respectively.
    The second-quarter 2005 results included the Company's continued
investment in its infrastructure, research and development, and
stock-based compensation expense. Stock-based compensation expense was
$5.3 million, compared to $2.1 million for the second quarter of
fiscal 2004.

    Operating highlights during the quarter include:

    --  Raised $247 million in initial public offering on the New York
        Stock Exchange effective on February 16, 2005.

    --  Company founder and Chairman Ray Dolby contributed
        intellectual property rights to the Company, eliminating
        future royalty obligations.

    --  Debuted Dolby(R) Digital Cinema system at ShoWest in Las
        Vegas.

    --  All films nominated for 2004 Oscars(R) in the Sound Editing
        and Sound Mixing categories incorporated Dolby Digital or
        Dolby Digital Surround EX(TM) technology.

    Business Outlook

    For fiscal 2005, revenue is expected to be in the range of $335
million to $350 million, compared to $289 million in fiscal 2004. Net
income for fiscal 2005 is expected to be between $49 million and $55
million, compared to $39.8 million in fiscal 2004. Pro forma net
income for fiscal 2005 is expected to be between $60 million and $67
million, compared to pro forma net income of $63.3 million in fiscal
2004. Earnings per diluted share for the full fiscal year 2005 are
expected to be in the range of $0.45 to $0.51 and, on a pro forma
basis, $0.55 to $0.62. This compares to $0.43 per diluted share and
$0.68 per diluted share, pro forma, in fiscal 2004. Stock-based
compensation expense for the full year is expected to be between $14
million and $15 million. EPS is estimated on a diluted share count of
108 million shares.
    As noted in its prospectus, the Company's operating results may
fluctuate due to a number of factors outside of the Company's control.
Because the Company does not manufacture or sell the products that
drive the licensing business, there is limited ability to control the
timing of revenue on a quarterly basis. As a result, the business is
managed over the long-term, focusing on year-over-year growth.
Therefore, the Company's policy is to provide guidance for the full
year.

    Pro Forma Information

    Throughout the Company's history, Ray Dolby retained ownership of
the intellectual property he created related to the Company's business
and licensed those rights to the Company in exchange for royalty
payments. In connection with the Company's IPO, Ray Dolby contributed
to the Company all of these intellectual property rights. The pro
forma financial information included in this release gives effect to
the asset contribution as though such transactions had been completed
prior to the beginning of fiscal 2004. The Company provides this
information because it believes the pro forma presentation more
accurately reflects the Company's financial position going forward. A
reconciliation of the Company's actual results to its pro forma
results is included in this release.

    Today, beginning at 2:00 p.m. PDT, Bill Jasper, President and CEO,
and Marty Jaffe, Executive Vice President Business and Finance, will
