 Dolby Laboratories Reports Financial Results for Third Quarter of
                           Fiscal Year 2005

    SAN FRANCISCO--(BUSINESS WIRE)--July 28, 2005--Dolby Laboratories
(NYSE:DLB) today announced the Company's financial results for the
third quarter of fiscal 2005 ended July 1, 2005. For the third
quarter, Dolby reported total revenue of $79.7 million, compared to
$76.1 million for the third quarter of fiscal 2004, an increase of 5%.
Third quarter net income was $14.8 million, or $0.13 per diluted
share, compared to $12.0 million, or $0.13 per diluted share, in the
same period a year ago. Per share calculations are based on 112.8
million diluted shares in the third quarter of fiscal 2005 compared
with 95.3 million diluted shares in the comparable year-ago quarter.
The increase in shares is principally attributable to the shares sold
by the Company in its February 2005 initial public offering (IPO).
    In connection with the Company's IPO, Ray Dolby contributed to the
Company all of his intellectual property rights related to the
Company's business, which he had previously licensed to the Company in
exchange for royalty payments. As a result of the contribution, the
Company's royalty obligations to Ray Dolby terminated in February
2005. As such, net income for the third quarter of fiscal 2005 did not
include any royalty obligations to Ray Dolby, while the third quarter
of fiscal 2004 included $9.2 million of such obligation payments. Pro
forma net income, which excludes royalty payments to Ray Dolby and
thus gives effect to the asset contribution as though such
transactions had been completed prior to the beginning of fiscal 2004,
was $14.8 million, or $0.13 per diluted share, for the third quarter
of fiscal 2005, compared to $17.6 million, or $0.18 per diluted share,
for the third quarter of fiscal 2004.
    Net income for the third quarter of fiscal 2005 also included
stock-based compensation charges of $3.2 million, compared to $2.3
million for the third quarter of fiscal 2004. Net income excluding
both the Ray Dolby royalty obligations and stock-based compensation
charges was $18.4 million, or $0.16 per diluted share, for the third
quarter of fiscal 2005, compared to $19.7 million, or $0.21 per
diluted share, for the third quarter of fiscal 2004.
    "The growth in quarterly revenue on a year-over-year basis was
driven primarily by higher licensing revenue attributable to the PC,
broadcast, and gaming markets. While we did note a slowdown in the
growth of sales of traditional consumer DVD players, the overall DVD
market is still growing," said Bill Jasper, President and Chief
Executive Officer, Dolby Laboratories. "We are pleased by this
quarter's key achievements, which we believe lay the groundwork for
the Company's future and enhance the overall entertainment
experience."

    Highlights from the quarter include the following:

    --  Dolby launched Dolby(R) Digital Cinema in select cinemas
        around the world with Star Wars: Episode III -- Revenge of the
        Sith.

    --  Together Dolby and Disney announced their collaboration for
        the first studio-supported digital cinema rollout plan to
        install Dolby Digital Cinema in 100 select cinemas nationwide
        in time for Disney's fall 2005 release of Chicken Little in
        digital 3-D.

    --  Shanghai Media Entertainment Group announced the first
        television channel in China's broadcasting history to offer
        5.1 programming, for which Dolby Digital 5.1 surround sound
        was selected.

    --  Three leading motherboard manufacturers, Abit, ASUSTeK, and
        Gigabyte, launched motherboards built on the Intel(R) Express
        Chipset with Intel High Definition Audio implementations that
        meet the Designed for Dolby Master Studio(TM) requirements,
        making it possible for PC enthusiasts to build PCs with audio
        performance and surround sound capabilities typically found in
        consumer electronics.

    --  In Europe, broadcasters continue to add 5.1 surround sound to
        new and existing services. Most recently, Premiere, the
        dominant pay-TV broadcaster in Germany, launched video-on-
        demand services using Dolby Digital 5.1. M6, one of France's
        leading broadcasters, also added Dolby Digital 5.1 surround
        sound for programming on both its new digital terrestrial
        television network and its network satellite service.

    --  Dolby's subsidiary, Via Licensing Corporation, announced final
        licensing terms and availability of a license for the IEEE
        802.11 standard, making Via the only group to run a joint
        patent licensing program for the most widely used wireless
        networking standard.

    Fiscal Year 2005: Year-To-Date

    For the nine-month period ended July 1, 2005, Dolby reported total
revenue of $249.0 million, compared to $220.2 million for the
nine-month period ended June 25, 2004. Net income for the nine-month
period ended July 1, 2005 was $35.5 million, or $0.34 per diluted
share, compared to $36.6 million, or $0.40 per diluted share, for the
nine-month period ended June 25, 2004. The Company had 105.0 million
diluted shares outstanding for the nine-month period ended July 1,
2005, compared with 91.1 million diluted shares for the nine-month
period ended June 25, 2004.
    Net income also included $18.7 million in now-discontinued royalty
obligations paid to Ray Dolby for the nine-month period ended July 1,
2005, and $28.0 million in royalty obligations paid to Ray Dolby for
the nine-month period ended June 25, 2004. Pro forma net income, which
excludes these royalty obligations, was $46.6 million, or $0.44 per
diluted share, for the nine-month period ended July 1, 2005, compared
to $53.8 million, or $0.59 per diluted share, for the nine-month
period ended June 25, 2004.
    Net income also included $11.4 million of stock-based compensation
for the nine-month period ended July 1, 2005, compared with a $4.4
million charge for the nine-month period ended June 25, 2004. Net
income excluding both royalty obligations payable to Ray Dolby and the
stock-based compensation charges was $57.5 million, or $0.55 per
diluted share, for the nine-month period ended July 1, 2005, compared
to $57.5 million, or $0.63 per diluted share, for the nine-month
period ended June 25, 2004.

    Guidance

    The Company currently expects revenue for fiscal 2005 to be at the
low end of its previously forecasted range of $335 million to $350
million. Net income for fiscal 2005 is still expected to be between
$49 million and $55 million. Pro forma net income, which excludes
royalty obligations to Ray Dolby, for fiscal 2005 is still expected to
be between $60 million and $67 million. Earnings per diluted share for
the full fiscal year 2005 are still expected to be in the range of
$0.45 to $0.51 and, on a pro forma basis, $0.55 to $0.62. Stock-based
compensation expense for the full year is still expected to be between
$14 million and $15 million. Net income excluding the royalty
obligations to Ray Dolby and stock-based compensation expense for
fiscal 2005 is expected to be in the range of $73 million and $80
million, or between $0.67 and $0.74 per diluted share.

    Pro Forma Information and Non-GAAP Measures

    Prior to the Company's IPO, 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. In addition, the Company
provides net income excluding royalties payable to Ray Dolby and
stock-based compensation, which is a non-GAAP measure. The Company
believes these are important metrics as they represent how profitable
the Company is exclusive of charges that have been eliminated in the
future or that resulted largely from the revaluation of the Company in
connection with its IPO. The Company uses these metrics internally to
measure its performance and believes these metrics may be meaningful
for investors in analyzing the Company's results of operations. A
reconciliation of the Company's actual results to these additional
metrics is included in this release.

 guidance
======================================================================

(a) Prior to the Company's IPO, 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. In addition, the Company provides net income excluding
    royalties payable to Ray Dolby and stock-based compensation, which
    is a non-GAAP measure. The Company believes these are important
    metrics as they represent how profitable the Company is exclusive
    of charges that have been eliminated in the future or that
    resulted largely from the revaluation of the Company in connection
    with its IPO. The Company uses these metrics internally to measure
    its performance and believes these metrics may be meaningful for
    investors in analyzing the Company's results of operations. A
    reconciliation of the Company's actual results to these additional
    metrics is included in this release.
