million in the prior quarter.
    For the third fiscal quarter, GAAP net income was $76.4 million,

    Quarterly Highlights

    This quarter, NetApp(R) was listed in the "leader" quadrant for
midrange enterprise disk arrays in Gartner's research note, "Magic
Quadrant for Midrange Enterprise Disk Array, 2H05."(3) NetApp SAN
solutions provide an unmatched combination of high-performance,
robustness, and ease-of-use for Windows(R), Solaris(R), HP/UX, IBM
AIX, and Linux(R) computing platforms.
    Also this quarter, according to IDC's Worldwide Quarterly Disk
Storage Systems Tracker Q3 2005(4), NetApp demonstrated continued
leadership in the iSCSI storage market, with number-one market share
in capacity shipped (38.4%) and revenue (35.1%). NetApp maintained
leadership in its core NAS market, with a 44.3% capacity share. Of the
vendors tracked, NetApp posted the strongest year-over-year increase
in FC SAN revenue, with a growth rate of 118%. Also according to IDC,
NetApp experienced the fastest growth among the top five vendors in
storage software with 49.4% year-over-year growth from Q2 2004 to Q2
2005 versus a market growth rate of 11.8% for the same period. Total
NetApp market share in storage software grew from 5% in Q2 2004 to
6.6% in Q2 2005.
    Earlier in the quarter, NetApp unveiled its Uncompromised Security
Initiative, a visionary program that challenges the status quo of data
security and promises to deliver industry-best solutions to the
enterprise. NetApp has numerous product lines shipping today that
enable it to deliver uncompromised security, including Decru(R)
DataFort(TM) storage security appliances, NetApp disk systems running
Data ONTAP(R) security features, and NetCache(R) internet access and
security appliances, as well as strong partnerships with leading
vendors such as Symantec that enhance the security portfolio. The
NetApp Uncompromised Security Initiative provides a vision and a
roadmap for customers who expect best-in-class data management,
coupled with military-grade security.
    In other product news, Network Appliance announced the NetCache

    Furthering the relationship with NetApp, this quarter IBM
announced the introduction of the IBM(R) System Storage(TM) N5000, a
new series of networked storage systems designed to help midrange
customers dramatically reduce their total cost of ownership,
particularly enterprises operating distributed networks across remote

offering resulting from IBM's relationship with NetApp announced in
April 2005.
    During the quarter, the FAS3020c was named "Best NAS Solution of
the Year" in InfoWorld's 2006 Technology of the Year honors. This
marked the second consecutive year that NetApp won Best NAS from
InfoWorld. In 2005, the NetApp FAS200 series also received the award.
    On the partner front, NetApp unveiled several new solution
enhancements and partner offerings with Acopia Networks, Cisco,
Microsoft and Network Intelligence to address a variety of data
concerns, including backup and recovery, file virtualization, data
migration, log management lifecycles, storage management and
consolidation.
    In corporate news, NetApp was named by FORTUNE magazine as one of
the "100 Best Companies to Work For" for the fourth consecutive year.
This year, NetApp again ranked in the top half of the list, at number
27, reflecting the company's emphasis on attracting and retaining the
best talent in the industry and continuing to demonstrate the values
of what NetApp CEO Dan Warmenhoven calls a "model company."

Hong Kong as part of the company's continuing worldwide expansion and

    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.
