    SUNNYVALE, Calif.--(BUSINESS WIRE)--Aug. 17, 2004--Network
Appliance, Inc. (Nasdaq:NTAP), the leader in advanced networked
storage solutions, today reported results for the first quarter of
fiscal year 2005. Revenues for the first fiscal quarter were $358.4
million, an increase of 38% compared to revenues of $260.5 million for
the same period a year ago and a 6% increase compared to $337.0
million in the prior quarter.
    For the first fiscal quarter, GAAP net income increased 73% to
$46.9 million, or $0.13 per share(1) compared to GAAP net income of
$27.1 million, or $0.08 per share for the same period in the prior
year. Pro forma(2) net income for the first fiscal quarter increased
73% to $49.9 million, or $0.13 per share, compared to pro forma net
income of $28.7 million, or $0.08 per share for the same period a year
ago.
    "NetApp demonstrated exceptional execution, a strong balance
sheet, and continued cash generation during the quarter. We continue
to drive our solutions deeper into our customers' data centers and
mission-critical areas to solve significant issues around business
continuity, regulatory compliance, and high data availability," said
Dan Warmenhoven, CEO of Network Appliance. "Our focus is on expanding
our market share and our results demonstrate that the market is
continuing to move toward us."

    Quarterly Highlights

    Throughout the first quarter of fiscal year 2005, Network
Appliance reinforced its leadership position by deploying new tier-one
storage solutions, expanding partnerships, and enhancing its storage
grid architecture. Customers deploying NetApp during the quarter for a
variety of database, collaborative, and other data center and
mission-critical applications included Audi AG, Canon, Catholic
Healthcare West, China Everbright Bank, Ciena, City of Concord,
ConocoPhillips, Fujitsu LTD, Gap Inc., GE Healthcare, Hearst
Corporation, ING BHF Bank, Pixar, Progress Energy, Qualcomm, Sprint,
Telstra, and University of Georgia. All levels of enterprise customers
have chosen to deploy NetApp for a variety of reasons -- reduced
complexity, a low total cost of ownership (TCO), and advanced
management capabilities made possible through Data ONTAP(TM) and a
range of additional storage software packages that unleash the value
of enterprise data.
    On the partners front, NetApp unveiled several new solution
enhancements and partner offerings with McData, Ontrack Data Recovery,
Oracle, Secure Computing, Symantec, Trend Micro, and VERITAS to
address a variety of data concerns, including e-mail recovery, unified
storage, and security issues facing enterprise customers.
    For storage grid architectures, the company continued to set the
pace for the rest of the industry in iSCSI and IP SAN (storage area
network), with more than 700 real-world production deployments to
date, and reinforced its leadership in other storage application areas
such as data protection/recovery, disk-based nearline storage, and
database storage. In database storage in particular, NetApp
demonstrated its prowess with large Oracle(R) deployments at Universal
Tax Systems and the South China Morning Post and received a
prestigious SAP Pinnacle Award for innovation around storage for SAP
environments. Finally, Network Appliance also debuted its new midrange
unified storage models, the FAS920 and FAS920c. Designed to provide
affordable enterprise-class performance, reliability and advanced data
management features for midrange applications, the FAS920 can power
applications in Fibre Channel and iSCSI SANs and network-attached
storage (NAS) simultaneously.
    In corporate news, Network Appliance recently announced that it is
the recipient of a Job Development Investment Grant (JDIG) from the
governor of North Carolina to assist in any expansion of newly
acquired NetApp offices in Research Triangle Park, North Carolina.
NetApp also added two new members to its board of directors: Mark
Leslie and George Shaheen.

    Network Appliance Usage of Pro Forma Financials

    The Company refers to the non-GAAP financial measures cited above
in making operating decisions because they provide meaningful
supplemental information regarding the Company's operational
performance. In addition, these non-GAAP financial measures facilitate
management's internal comparisons to the Company's historical
operating results and comparisons to competitors' operating results.
We include these non-GAAP financial measures in our earnings
announcement because we believe they are useful to investors in
allowing for greater transparency with respect to supplemental
information used by management in its financial and operational
decision-making such as employee compensation planning. In addition,
we have historically reported similar non-GAAP financial measures to
our investors and believe that the inclusion of comparative numbers
provides consistency in our financial reporting at this time.
