    Quarterly Highlights

    During the fourth quarter of fiscal year 2006, Network Appliance
further expanded its breadth of disk-to-disk backup and security
solutions, enhanced its Fibre Channel data management offerings, and
continued its leadership position in the iSCSI and network-attached
storage (NAS) markets.
    Earlier in the quarter, NetApp introduced an array of products,
technologies, and services that highlight the broad range of NetApp(R)

NetApp disk-to-disk backup family, including two offerings in the new
NearStore(R) Virtual Tape Library (VTL) family, new Decru DataFort(TM)
E-Series functionality for unified NAS-iSCSI protocol support, and
enhanced capabilities for NetApp customers to protect their remote
office/branch office (ROBO) data as well as that in their data
centers. Complementary new services announced this quarter included a
VTL Design and Implementation Service, a Disaster Recovery Design and
Implementation Service, and a Backup and Recovery Design and
Implementation Service.
    NetApp SnapManager(R) for Microsoft(R) Exchange software achieved
Microsoft Simple SAN designation for Microsoft Windows(R) Server

designation demonstrates to the market that NetApp and Microsoft are
providing solutions for quick recovery of Exchange Server 2003 SP2.
    This quarter, the company introduced its SnapSearch and Recovery
software, the industry's first solution for search and recovery of
online backup data. The new software enables customers to quickly and
efficiently recover specific files from backup and archive data in
minutes.
    In other product news, NetApp announced its storage solutions will
now support 4Gb Fibre Channel (FC). 4Gb FC combined with NetApp
unified storage systems and leading-edge data management software
gives customers a compelling and powerful solution for managing large
and ever-growing amounts of data. NetApp 4Gb FC will allow customers
to increase the performance and availability of critical data and
applications, while simplifying complex data management environments,
improving productivity in application administration, and lowering
storage costs.
    This quarter, NetApp announced that according to IDC's Worldwide
Quarterly Disk Storage Systems Tracker Q4 2005(3) (as of December
2005), it maintained its position as the market leader in iSCSI in
both revenue and capacity for the prior 11 quarters and continued its
leadership in capacity market share in NAS. NetApp demonstrated
continued leadership in the iSCSI storage market, with number-one
market share in capacity shipped (34.6%) and revenue (32.0%) for the
full year 2005. In FC SAN, NetApp nearly doubled its year-end 2005
revenue market share to 1.6%, up from 0.9% in 2004, doubled its unit
share to 2.2% from 1.1%, and grew capacity shipped by 230%. Finally,
NetApp maintained leadership in its core NAS market, with a 42.6%
capacity market share, and grew capacity shipped by 56% from year end
2004.
    Also this quarter, NetApp extended its position in the NAS and
unified storage market according to Gartner's report "Market Share:
NAS/Unified Storage, Worldwide, 2000-2005."(4) The total NAS and
unified storage market grew 16.1% in 2005 and NetApp grew more quickly
than the market, posting annual revenue growth of 22.4%. According to
Gartner, the company increased its market share from 52.4% in 2004 to
55.2% in 2005. NetApp leads in both the high-end and midrange parts of
the market, with 88.9% market share and 70.5% market share by revenue
respectively.
    On the partner front, NetApp unveiled several new solution
enhancements and partner offerings with BakBone, Bocada, LogLogic,
Microsoft, Syncsort and Topio to address a variety of data concerns,
including data protection, compliance, data management, backup and
recovery, and data replication.
    In corporate news, NetApp debuted at number 929 on the FORTUNE
1000 list, the magazine's annual ranking of America's largest
corporations determined by revenue. This quarter NetApp also announced
the 2005 NetApp Innovation Award winners. The NetApp Innovation Awards

    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. These non-GAAP financial measures exclude amortization of
intangible assets, in-process research and development, stock
compensation, restructuring charges/recoveries, net gain/loss on
investments and the related effects on income taxes, as well as
certain discrete GAAP provision for income tax matters recognized
ratably for non-GAAP purposes. We have excluded these items because
they derive from unusual events that are not attributable to normal on
going operations and thus makes it more difficult for an investor to
understand our recurring operational performance. The use of these
non-GAAP financial measures has material limitations because they
should not be used to evaluate our company without reference to their
corresponding GAAP financial measures. As such, we compensate for
these material limitations by using these non-GAAP financial measures
in conjunction with GAAP financial measures.
    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.
