     Network Appliance Announces Results for First Quarter Fiscal Year 2006


    SUNNYVALE, Calif.--(BUSINESS WIRE)--Aug. 17, 2005--Network
Appliance, Inc. (NASDAQ:NTAP), the leader in advanced networked
storage solutions, today reported results for the first quarter of
fiscal year 2006. Revenues for the first fiscal quarter were $448.4
million, an increase of 25% compared to revenues of $358.4 million for
the same period a year ago and a decrease of 1% compared to $451.8
million in the prior quarter.
    For the first fiscal quarter, GAAP net income was $60.1 million,
or $0.16 per share(1) compared to GAAP net income of $46.9 million, or
$0.13 per share for the same period in the prior year. Non-GAAP(2) net
income for the first fiscal quarter was $62.1 million, or $0.16 per
share, compared to non-GAAP net income of $49.9 million, or $0.13 per
share for the same period a year ago.
    "With 25% revenue growth, we continue to grow significantly faster
than the storage market and gain share. We are pleased with the
success of our new FAS3000 midrange product line, despite the product
transition issues that resulted in revenues a little short of our
expectations," said Dan Warmenhoven, CEO of Network Appliance. "We are
also encouraged by our growing relationships with partners,
particularly IBM's recent introduction of their first product
resulting from our OEM agreement."

    Outlook

    --  Network Appliance estimates that year-over-year growth in
        revenue for the second quarter of fiscal year 2006 will be in
        the range of 25% to 28%. This projection reflects a
        quarter-over-quarter sequential growth rate of approximately
        5% to 7%.

    --  The company expects second quarter GAAP earnings per share to
        finish between $0.17 and $0.18 per share. Network Appliance
        expects second quarter non-GAAP earnings per share to be in
        the range of $0.18 to $0.19 per share.

    --  For the full fiscal year, Network Appliance estimates that
        revenues will finish in the range of 25% to 28% higher than
        fiscal year 2005.

    --  The company expects GAAP earnings per share for fiscal year
        2006 to be between $0.74 and $0.77 per share. Network
        Appliance estimates full-year non-GAAP earnings per share to
        be in the range of $0.76 to $0.79 per share.

    Quarterly Highlights

    During the first quarter of fiscal year 2006, Network Appliance
extended its leadership in data protection through a definitive
agreement to acquire Decru, expanded its footprint in midrange storage
and in global service offerings, and advanced its relationship with
IBM in the virtualization and NAS markets.
    In this quarter, NetApp entered into a definitive agreement to
acquire Decru, a privately held company based in Redwood City,
California, for approximately $272 million in cash and stock. Decru, a
market leader in storage security, offers data protection solutions to
address a range of needs for enterprises and governments, including
regulatory compliance, privacy, secure consolidation, and outsourcing.
Decru DataFort(TM) appliances protect the core of the storage network
by seamlessly inserting a layer of strong encryption, authentication,
access controls, and compartmentalization. Since January 2004, NetApp
and Decru have worked together to deliver solutions to customers in
sectors including investment banking, healthcare, semiconductors,
software, and the federal government. This acquisition is expected to
close during the second quarter of fiscal year 2006, subject to
receipt of required regulatory approvals and other customary closing
conditions.
    Also during the quarter, NetApp and IBM announced their intention
to extend their strong relationship to encompass the growing
technologies of virtualization and blade solutions. The focus is on
combining IBM's storage virtualization technologies and the full line
of NetApp V-Series and FAS storage systems into integrated solutions,
signaling the beginning of efforts to collaborate to exploit the
synergies between the companies' respective virtualization
technologies. NetApp also announced that it plans to join IBM as one
of nine founding members in the new Blade.org industry community. The
community was conceived to enhance the relationships between the
founding members and to serve as a catalyst for the industry to create
new blade technology. NetApp is already providing back-end storage
systems for IBM eServer(R) BladeCenter(TM).
    On the product front, NetApp unveiled two new midrange storage
systems -- the NetApp FAS3020 and FAS3050 plus a new serial ATA (SATA)
option for primary storage applications. Concurrently, NetApp debuted
two new V-Series virtualization engines -- the NetApp V3020 and V3050.
These new solutions, combined with Data ONTAP(TM) 7G software, address
three significant customer pain points -- high storage acquisition
costs, low storage resource utilization, and increasing storage
management costs -- with elegant, powerful, and scalable solutions
that help today's enterprise tailor its storage needs to its business
and data demands. The new systems also significantly increase NetApp
midrange performance.
    Additionally, NetApp debuted two new midrange NetCache systems --
the NetApp C2300 and C3300 -- to strengthen the company's Internet
access and security solution for enterprise data centers. The C2300
and C3300 provide more midrange deployment options than the previous
NetCache portfolio. The new systems double NetCache price performance
compared to older NetCache systems.
    NetApp maintained its leadership in the Secure Content and
Application Delivery market for the fourth consecutive time according
to IDC's (3)Secure Content and Application Delivery 2005-2009 Forecast
and Analysis, IDC# 33455. According to IDC, in 2004, NetApp captured
32.1% of the revenue market share and maintained a leadership position
with its NetCache customer offerings, which include solutions for
Internet access and security, streaming media, and business
application acceleration. Overall, the secure content and application
delivery market grew by 15% from 2003 to 2004.
    In service and support, NetApp announced a new generation of its
service and support offering, ConsultingEdge, with six packaged
consulting and integration services, designed to simplify complex
storage and data management needs and speed time to production of
NetApp solutions within customers' data infrastructures and the first
support solution designed exclusively for government agencies,
SupportEdge Secure for Government. NetApp SupportEdge Secure for
Government is a highly customized service package that provides
confidential and secure assistance in the support and management of
NetApp storage solutions to both classified and nonclassified
government agencies. With this offering, NetApp has designed a
pioneering set of tools that allows filtering of restricted or
classified information from government files prior to making them
available for troubleshooting purposes.
    On the partner front, NetApp unveiled several new solution
enhancements and partner offerings with Arkivio, Decru, FileNet,
Interwoven, Microsoft, SAP, and Symantec to address a variety of data
concerns including bringing scalability to ILM, compliance, IP SAN
support, content management, enhancing data protection and consumer
data security, increased data recovery, SQL server support, enhanced
storage management and other business-critical initiatives facing
enterprise customers.
    In corporate news, NetApp was named by IDG's Computerworld as one
of the "100 Best Places to Work in IT." NetApp ranked in fifth place
on an impressive list of U.S. companies spanning several industries,
based on employee feedback. NetApp also appointed Jeffry R. Allen to
its board of directors. Allen transitioned to the board from his
former role as the executive vice president of Business Operations at
Network Appliance. Allen's appointment brought the number on the
Network Appliance board to 10.

    Network Appliance Usage of Non-GAAP 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.
