    "Fiscal 2005 was an outstanding year for Network Appliance. We

innovative products targeted at the areas of fastest growth in
storage," said Dan Warmenhoven, CEO of Network Appliance. "Our
continued investments in our business, combined with expanded
partnerships with strategic vendors such as IBM, Microsoft, SAP, and
VERITAS, lay the foundation for providing even greater value to our
customers."

    Outlook

    --  Network Appliance estimates that revenue for the first quarter
        of fiscal year 2006 will grow sequentially by 3% to 6%. This
        projection reflects year-over-year growth rates of 30% to 33%.

    --  The company expects first quarter pro forma earnings per share
        to finish at $0.17 to $0.18 per share. First quarter GAAP
        earnings per share are projected to finish at $0.16 to $0.17
        per share.

    --  For the full fiscal year, Network Appliance estimates that
        revenues will finish 32% to 35% higher than fiscal year 2005.

    --  Network Appliance estimates full-year pro forma earnings per
        share to finish at $0.76 to $0.80 per share. GAAP earnings per
        share are projected for fiscal year 2006 at $0.73 to $0.77 per
        share.

    Quarterly Highlights

    During the fourth quarter of fiscal year 2005, Network Appliance
reinforced its leadership position through a strategic original
equipment manufacturing (OEM) relationship with IBM, increased growth
in storage software and SAN, and continued leadership in the iSCSI and
network-attached storage (NAS) markets.
    This quarter, NetApp and IBM entered into an OEM agreement that
will enable IBM to sell IBM-branded solutions based on Network
Appliance(TM) unified and open network attached storage NAS and
iSCSI/IP SAN solutions, including NearStore(R) and NetApp V-Series
systems, as well as associated software offerings. For more
information, please see our April 6, 2005 press release posted on the
NetApp Web site.
    Also this quarter, NetApp acquired Alacritus, a privately held
company based in Pleasanton, California. The acquisition will extend
the company's ability to provide a robust data protection solution to
NetApp customers and help accelerate customer transitions to
disk-based backup. Alacritus is best known for its Virtual Tape
Library (VTL) software product, which makes disks emulate tape to
provide high performance for large-scale backup environments without
disrupting established tape backup workflow and processes.
    On the product front, NetApp announced the latest addition to its
data management and virtualization portfolio, the NetApp V-Series
family which unifies SAN, IP SAN, and NAS under a common architecture.
V-Series systems enable customers to extend the complete suite of
groundbreaking dynamic virtualization capabilities delivered in NetApp
Data ONTAP(TM) 7G software to third-party storage products from HDS,
HP, IBM, and Sun. The unique virtualization capabilities of V-Series
systems translate directly into customer cost savings and a more
intelligent, fluid approach to storage asset utilization that
accommodates shifting business demands. V-Series systems facilitate a
single, powerful, flexible management paradigm that replaces the
cumbersome management procedures of conventional arrays.
    VERITAS Software Corporation and NetApp announced the availability
of new integrated disk-based data protection and data management
solutions for multi-vendor environments. The two companies integrated
the latest version of VERITAS NetBackup(TM) software with NetApp
NearStore storage systems and SnapVault software to help customers
significantly reduce their backup and restore times with disk-based
protection, while still retaining data on tape for long-term archival
and disaster recovery -- all through a common management console.
NetBackup 6.0 integration with NetApp storage provides cost savings
when using NearStore single-instance storage capabilities to eliminate
redundant heterogeneous backup data. Customers can now store hundreds
of backups online with minimal storage.
    NetApp and VERITAS have also collaborated to integrate VERITAS
Enterprise Vault(TM) 6.0 software with NetApp NearStore and
SnapLock(TM) products. These integrated products offer powerful
solutions to help mutual customers cope with growing compliance and
regulatory requirements by delivering solutions that allow them to
transparently archive data and quickly retrieve specific information
as needed.
    NetApp demonstrated the strongest growth in storage software
according to Gartner's report "Market Share: Storage Management
Software, Worldwide, 2004."(3) The total market for new license
revenue in 2003 to 2004 grew at a rate of 12.3%, with Network
Appliance beating the market with a growth rate of 73.5% for the same
period. NetApp showed the strongest market share growth among the top
10 vendors of storage software and has moved into the top five vendors
for marketshare in 2004. For the second year in a row, this was the
fastest growth rate among the top 10 vendors in the space and for the
first year places NetApp in the top five with a total overall market
share of 5.2%.
    NetApp maintained its leadership position in both the NAS and
iSCSI storage markets for calendar year 2004 (CY2004). According to
IDC's Worldwide Quarterly Disk Storage Systems Tracker Q4 2004,(4)
NetApp demonstrated continued leadership in its core NAS market, with
a 36.9% revenue share and maintained its strong lead in the iSCSI
storage market, with a 43% revenue share for CY2004. In addition,
NetApp remained the leader in the IP storage market (NAS and iSCSI),
posting a 37.3% market share in CY2004. Also according to IDC, the
company grew revenue in the open systems networked storage market,
with 29.7% year-over-year (fourth quarter 2003 to fourth quarter 2004)
growth, versus overall market growth of 11.6%. NetApp grew revenue in
the open SAN market at 98.9%, versus the market growth of 9.2%,
year-over-year (fourth quarter 2003 to fourth quarter 2004).
    On the partner front, NetApp announced support of Microsoft(R)
Windows(R) iSCSI Initiator 2.0. Support of the initiator demonstrates
the rapid integration of NetApp storage solutions with the latest
Microsoft Windows storage technologies. NetApp is among the first to
support Microsoft's latest version of its iSCSI initiator, which
underscores a continued vision by both companies to embrace the iSCSI
protocol for the benefit of enterprise customers. NetApp also unveiled
several new solution enhancements and partner offerings with Asigra,
Filenet, Maranti, Microsoft, Mobius, and Sun Microsystems to address a
variety of data concerns, including simplifying SQL Server
integration, content management, compliance, data backup and recovery,
data management, security, and other business-critical initiatives
facing enterprise customers.

    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.
