Network Appliance Announces Results for Third Quarter Fiscal Year 2007

              Achieves 36% Year-over-Year Revenue Growth


    SUNNYVALE, Calif.--(BUSINESS WIRE)--Feb. 14, 2007--Network
Appliance, Inc. (NASDAQ:NTAP), the leader in advanced networked
storage solutions, today reported results for the third quarter of
fiscal year 2007. Revenues for the third fiscal quarter were $729.3
million, an increase of 36% compared to revenues of $537.0 million for
the same period a year ago and an increase of 12% compared to $652.5
million in the prior quarter.

    For the third fiscal quarter, GAAP net income was $66.5 million,
or $0.17 per share(1)compared to GAAP net income of $76.4 million, or
$0.20 per share for the same period in the prior year. Non-GAAP(2) net
income for the third fiscal quarter increased 31% to $111.1 million,
or $0.29 per share, compared to non-GAAP net income of $84.7 million,
or $0.22 per share for the same period a year ago.

    Revenues for the first nine months of the current fiscal year
totaled $2.0 billion, compared to revenues of $1.47 billion for the
first nine months of the prior year, an increase of 36% year over
year.

    For the first nine months of the current fiscal year, GAAP net

net income of $207.2 million, or $0.54 per share for the same period

    "Our third quarter performance again demonstrates that customers
increasingly understand the NetApp data management value proposition,"
said Dan Warmenhoven, chief executive officer. "With revenues up 36%
over Q3 of last year, and 100 petabytes of storage shipped during the
quarter, NetApp is quickly becoming the vendor of choice for
enterprise customers' storage and data management needs."

    Outlook

    --  Network Appliance estimates that sequential growth in revenue
        for the fourth quarter of fiscal year 2007 will be in the
        range of 8% to 10%, which translates to 32% to 34% growth year
        over year.

    --  Including the implementation of SFAS123(R) and with current
        information and assumptions, the company expects fourth

        non-GAAP earnings to round to $0.30 per share.

    --  For the full fiscal year 2007, Network Appliance estimates
        that revenues will finish in the range of 35% to 36% higher
        than fiscal year 2006.

    --  Including the implementation of SFAS123(R) and with current
        information and assumptions, the company expects GAAP earnings
        per share for fiscal year 2007 to be about $0.73 per share.

        share will finish between $1.11 to $1.12 per share.

    Quarterly Highlights

    During the third quarter of fiscal year 2007, Network Appliance
continued to enhance its data management and data protection
portfolios with a key acquisition and several product announcements.
It also extended its data center portfolio with several additions
including new midrange platforms, broader Fibre Channel (FC) storage
area network (SAN) capabilities and significant enhancements in the
NetApp(R) Manageability Software Family. The company also continued to
gain momentum in the storage area network (SAN) market while
maintaining strong leadership in both the network-attached storage
(NAS) and iSCSI markets.

    This quarter, NetApp completed the acquisition of Topio, a
privately held Santa Clara, California-based company with R&D in
Haifa, Israel. The acquisition continues to expand the NetApp data
protection portfolio by adding heterogeneous disaster recovery
capabilities to existing heterogeneous disk-to-disk backup solutions
from NetApp. In addition to delivering a broader range of data
protection, data migration, and data cloning capabilities, this
acquisition expands the NetApp heterogeneous data protection portfolio
by simplifying the replication of data from other storage arrays to
NetApp storage systems.

    Also during the third quarter, NetApp extended its data center
portfolio with the addition of its highest-performing midrange
platforms, the FAS3070 and V3070 series; broader FC SAN capabilities;
significant enhancements and introductions in the NetApp Manageability
Software Family; and new professional services, all aimed at making
enterprise data center management easier for customers who demand
high-performance SAN solutions and increased application uptime to
meet their business needs.

    From a market perspective, according to IDC's Worldwide Quarterly
Disk Storage Systems Tracker Q3 2006(3), NetApp gained share in both
capacity shipped and revenue for the FC SAN market. NetApp also
continued to grow faster than the market in FC SAN in both revenue and
capacity, year over year. For capacity shipped, NetApp grew at 210.2%,
while the market grew at 46.3%. In terms of revenue, NetApp grew
faster than the market for the 11th consecutive quarter at 62.1%,
while the market grew at 14.1%. Sequentially, NetApp grew at 16.0%,
while the market grew at 6.4%.

    NetApp also demonstrated continued leadership in the NAS and iSCSI
storage markets in the third quarter, according to IDC. NetApp
maintained the number-one market share position in capacity shipped
for NAS (42.0%) and in iSCSI for both capacity shipped (32.6%) and
revenue (21.5%).

    In IDC's calculations of the network storage market (which
includes SAN, NAS, and iSCSI), NetApp grew faster than the market,
year over year, in both capacity shipped and revenue. For capacity
shipped, NetApp grew at 106.8%, while the market grew at 62.6%. In
terms of revenue, NetApp grew 18.9%, while the market grew at 17.2%.

    Also this quarter, NetApp continued its midrange leadership with
the news that it has been positioned by Gartner, Inc., in the
"Leaders" quadrant for midrange enterprise disk arrays in its research
note, "Magic Quadrant for Midrange Enterprise Disk Array, 2H06"(4) .

    On the partner front, NetApp announced general availability of two
software products in support of Microsoft(R) Exchange Server 2007.
NetApp SnapManager(R) 4.0 for Exchange Server and NetApp Single
Mailbox Recovery 4.2, a near-instantaneous backup and recovery
software solution for Exchange Server 2007, provide customers with
enterprise-class backup, recovery, and restoration solutions. With the
availability of these products, NetApp is helping Exchange Server 2007
customers achieve near-instantaneous, granular recovery of Exchange
Server data without a prohibitive--and expensive--increase in storage
capacity needs.

    In corporate news, NetApp was named by FORTUNE magazine as one of
the "100 Best Companies to Work For" for the fifth consecutive year.
This year, NetApp ranked in the top 10 of the list, at number six,
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." Also this
quarter, NetApp was named to Forbes magazine's "400 Best Big Companies
in America" list for 2007.

    This quarter, Dave Hitz, EVP and cofounder of Network Appliance,
was inducted into the CRN Industry Hall of Fame for developing a
disruptive technology that altered the landscape of the storage
industry.

    And finally, NetApp was honored as the 2006 Entrepreneurial
Company of the Year by the Peninsula Chapter of the Stanford Business
School Alumni Association.

    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, other acquisition-related cost, 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 in order to enhance investors' understanding of
our ongoing operations. 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.
