    Equinix, Inc. (Nasdaq:EQIX), the leading provider of
network-neutral data centers and Internet exchange services, today
reported its quarterly results for the period ended March 31, 2006.
    Revenues were $64.9 million for the first quarter, a 5% increase
over the previous quarter and a 33% increase over the same quarter
last year. Recurring revenues, consisting primarily of colocation,
interconnection and managed services, were $61.8 million, a 6%
increase over the previous quarter and a 35% increase over the same
quarter last year. Non-recurring revenues were $3.1 million in the
quarter, consisting primarily of professional services and
installation fees.
    Note: Equinix uses non-GAAP financial measures, such as EBITDA,
cash cost of revenues, cash gross margins, cash operating expenses
(also known as cash selling, general and administrative expenses or
cash SG&A), non-GAAP net income (loss), free cash flow and adjusted
free cash flow to evaluate its operations. A reconciliation of these
non-GAAP financial measures to the most closely applicable GAAP
financial measure is attached to this release and commences at the
bottom of our condensed consolidated statements of operations -- GAAP
presentation.
    Cost of revenues were $43.3 million for the first quarter,
including $758,000 of stock-based compensation, a 4% increase over the
previous quarter and an 18% increase over the same quarter last year.
Cost of revenues, excluding depreciation, amortization, accretion and
stock-based compensation of $18.0 million, were $25.3 million for the
first quarter, flat over the previous quarter and a 15% increase over
the same quarter last year. Cash gross margins, defined as gross
profit less depreciation, amortization, accretion and stock-based
compensation, divided by revenues, for the quarter were 61%, up from
59% the previous quarter and 55% the same quarter last year.
    Selling, general and administrative expenses were $24.3 million
for the first quarter, including $7.0 million of stock-based
compensation, a 41% increase over the previous quarter and a 59%
increase over the same quarter last year. Selling, general and
administrative expenses, excluding depreciation, amortization and
stock-based compensation of $7.5 million, were $16.8 million for the
first quarter, a 13% increase over the previous quarter and a 35%
increase over same quarter last year.
    Net loss for the first quarter, including stock-based compensation
expense of $7.8 million, was $5.1 million. This represents a basic and
diluted net loss per share of $0.18 based on a weighted average share
count of 27.8 million. Excluding stock-based compensation, the Company
was net income positive for the first quarter, with a non-GAAP net
income of $2.7 million. This was down $508,000 from the previous
quarter's result of $3.2 million, and a $6.0 million improvement over
the same quarter last year.
    EBITDA, defined as income or loss from operations before
depreciation, amortization, accretion, stock-based compensation
expense and restructuring charges, for the first quarter was $22.8
million, up 5% over the previous quarter and up from $14.3 million the
same quarter last year.
    Capital expenditures in the first quarter were $26.6 million, of
which $6.9 million was attributed to ongoing capital expenditures and
$19.7 million was attributed to expansion capital expenditures.
    The Company generated cash from operating activities of $12.8
million as compared to $18.6 million in the previous quarter. Cash
used in investing activities was $24.1 million as compared to $65.9
million in the previous quarter. Adjusted free cash flow was a
negative $11.3 million in the first quarter. Adjusted free cash flow
is defined as net cash generated from operating activities less net
cash used in investing activities (excluding the purchases, sales and
maturities of short-term and long-term investments and the purchase
and sale of real estate).
    As of March 31, 2006, the Company's cash, cash equivalents and
investments were $162.2 million after repaying $30.0 million under the
Silicon Valley Bank line of credit, as compared to $188.9 million in
the previous quarter.

    Other Company Developments & Metrics

    --  On a same IBX basis (defined as IBX centers which have been
        available for new customer installs for at least four full
        quarters), revenues were $62.5 million; cost of revenues were
        $38.8 million; cost of revenues, excluding depreciation,
        amortization, accretion and stock-based compensation, were
        $22.5 million and cash gross margins for the quarter were 64%.
        EBITDA on a same IBX basis was $23.5 million. These results
        now include Equinix's Washington, D.C. area center opened in
        December 2004.

    --  Equinix added 61 new customers in the quarter including iGames
        Online, LeBoeuf Lamb, McGraw-Hill, MovieClick, Packet
        Exchange, Trip Advisor and YouTube.

    --  Based on a total cabinet capacity of approximately 26,000, the
        number of cabinets billing at the end of the quarter was
        approximately 14,750, or 57%, up from approximately 14,100 the
        previous quarter. On a weighted average basis, the number of
        cabinets billing was approximately 14,500, representing a
        utilization rate of 56%.

    --  U.S. interconnection service revenues were 21% of U.S.
        recurring revenues for the quarter. Interconnection services
        represent greater than 19% of total worldwide recurring
        revenues. Equinix signed additional customers on its new 10
        Gigabit Ethernet service including Hurricane Electric and UPC
        Broadband.

    --  After more than six years on the Equinix Board of Directors,
        Mike Volpi will not stand for re-election to the Board. Mr.
        Volpi has decided to dedicate more time to his business
        priorities at Cisco. He will remain on the Equinix Board until
        June 8, 2006.

    Business Outlook

    For the second quarter 2006, revenues are expected to be in the
range of $67.5 to $68.5 million. Cash gross margins will be
approximately 60%. Cash selling, general and administrative expenses
are expected to be approximately $16.5 million. EBITDA for the second
quarter is expected to be $24.0 to $25.0 million. Net loss is expected
to be approximately $5.0 million, including the impact of
approximately $8.0 million of stock-based compensation expense. Net
interest expense will be approximately $2.0 million. The weighted
average shares outstanding will be approximately 28.4 million. Capital
expenditures are expected to be approximately $30.0 to $35.0 million,
including $20.0 to $25.0 million of expansion capital expenditures.
    For the full year of 2006, total revenues are expected to be in
the range of $280.0 to $286.0 million. Cash gross margins are expected
to be in the range of 58% to 60%, including the full year impact of
approximately $4.0 million of additional cost of revenues from three
new IBX centers. Cash selling, general and administrative expenses are
expected to be approximately $64.0 million, including approximately
$4.4 million of investments in expansion efforts. EBITDA for the year
is expected to be $100.0 to $105.0 million. Net loss for the year is
expected to be approximately $15.0 million, including the impact of
approximately $30.0 million of stock-based compensation expense. Net
interest expense will be approximately $9.0 million. Capital
expenditures for 2006 are expected to be in a range of $100.0 to
$105.0 million, comprised of approximately $25.0 million of ongoing
capital expenditures and $75.0 to $80.0 million of expansion capital
expenditures for the build out of the Chicago, Los Angeles and Silicon
Valley expansions, as well as the expansion build out in the
Washington, D.C. area campus. We expect our adjusted free cash flow to
be in a range of negative $5.0 to $10.0 million for the year. Adjusted
free cash flow is defined as net cash generated from operating
activities less net cash used in investing activities (excluding the
purchases, sales and maturities of short-term and long-term
investments, as well as purchases and sales of real estate).

    Non-GAAP Financial Measures

    Equinix continues to provide all information required in
accordance with generally accepted accounting principles (GAAP), but
it believes that evaluating its ongoing operating results may be
difficult if limited to reviewing only GAAP financial measures.
Accordingly, Equinix uses non-GAAP financial measures, such as EBITDA,
cash cost of revenues, cash gross margins, cash operating expenses
(also known as cash selling, general and administrative expenses or
cash SG&A), non-GAAP net income (loss), free cash flow and adjusted
free cash flow to evaluate its operations. In presenting these
non-GAAP financial measures, Equinix excludes certain non-cash or
non-recurring items that it believes are not good indicators of the
Company's current or future operating performance. These non-cash or
non-recurring items are depreciation, amortization, accretion,
stock-based compensation and restructuring charges. Recent legislative
and regulatory changes encourage use of and emphasis on GAAP financial
metrics and require companies to explain why non-GAAP financial
metrics are relevant to management and investors. Equinix excludes
these non-cash or non-recurring items in order for Equinix's lenders,
investors, and industry analysts who review and report on the Company,
to better evaluate the Company's operating performance and cash
spending levels relative to its industry sector and competitor base.
    Equinix excludes depreciation expense as these charges primarily
relate to the initial construction costs of our IBX centers and IBX
expansion projects or acquired IBX centers and do not reflect our
current or future cash spending levels to support our business. Our
IBX centers are long-lived assets, and have an economic life greater
than ten years. The construction costs of our IBX centers do not recur
and future capital expenditures remain minor relative to our initial
investment. This is a trend we expect to continue. In addition,
depreciation is also based on the estimated useful lives of our IBX
centers. These estimates could vary from actual performance of the
asset, are based on historic costs incurred to build out our IBX
centers, and are not indicative of current or expected future capital
expenditures. Therefore, Equinix excludes depreciation from its
operating results when evaluating its operations.
    In addition, in presenting the non-GAAP financial measures,
Equinix excludes amortization expense related to certain intangible
assets, as it represents a non-cash cost that may not recur and is not
a good indicator of the Company's current or future operating
performance. Equinix excludes accretion expense, both as it relates to
its asset retirement obligations as well as its accrued restructuring
charge liabilities, as these expenses represent costs, which Equinix
believes are not meaningful in evaluating the Company's current
operations. Equinix excludes non-cash stock-based compensation expense
as it represents expense attributed to stock awards that have no
current or future cash obligations. As such, we, and our investors and
analysts, exclude this stock-based compensation expense when assessing
the cash generating performance of our operations. The restructuring
charges relate to the Company's decision to exit leases for excess
space adjacent to several of our IBX centers, which we do not intend
to build out now or in the future. Management believes such
restructuring charges were unique costs that are not expected to
recur, and consequently, does not consider these charges as a normal
component of expenses related to current and ongoing operations.
    Our management does not itself, nor does it suggest that investors
should, consider such non-GAAP financial measures in isolation from,
or as a substitute for, financial information prepared in accordance
with GAAP. However, we have presented such non-GAAP financial measures
to provide investors with an additional tool to evaluate our operating
results in a manner that focuses on what management believes to be our
ongoing business operations. Management believes that the inclusion of
these non-GAAP financial measures provide consistency and
comparability with past reports and provide a better understanding of
the overall performance of the business and its ability to perform in
subsequent periods. Equinix believes that if it did not provide such
non-GAAP financial information, investors would not have all the
necessary data to analyze Equinix effectively.
    Investors should note, however, that the non-GAAP financial
measures used by Equinix may not be the same non-GAAP financial
measures, and may not be calculated in the same manner, as that of
other companies. In addition, whenever Equinix uses such non-GAAP
financial measures, it provides a reconciliation of non-GAAP financial
measures to the most closely applicable GAAP financial measure.
Investors are encouraged to review the related GAAP financial measures
and the reconciliation of these non-GAAP financial measures to their
most directly comparable GAAP financial measure.
    Equinix does not provide forward-looking guidance for certain
financial data, such as depreciation, amortization, accretion, net
income (loss) from operations, interest income, cash generated from
operating activities and cash used in investing activities, and as a
result, is not able to provide a reconciliation of GAAP to non-GAAP
financial measures for forward-looking data. Equinix intends to
calculate the various non-GAAP financial measures in future periods
consistent with how it was calculated for the three months ended March
31, 2006 and 2005, presented within this press release.
