anchor bookings in our new Washington, D.C. and Silicon Valley IBX
centers contributed to our momentum."

    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), cash interest expense and cash net income (loss) and 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, non-cash interest, and, with respect to 2004
results, the non-cash portion of loss on debt extinguishment and
conversion and restructuring charges (there were no such charges or
losses in 2005). 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 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 liability, 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. Equinix excludes
interest expense associated with the amortization of debt issuance
costs and discounts, as well as the interest expense associated with
its convertible secured notes as such interest expenses do not require
any cash in the periods presented nor will they in future periods.
Lastly, with respect to its 2004 results, Equinix excludes
restructuring charges and the non-cash portion of the loss on debt
extinguishment and conversion. 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. The non-cash portion of the loss on debt extinguishment and
conversion, which represents the write-off of the unamortized debt
issuance costs and discounts associated with the debt facilities
extinguished or converted as no cash was expended in the periods
presented for such write-offs nor will there be in the future.
Management believes such restructuring charges and write-offs of debt
issuance costs and discounts 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 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, 2005 and 2004, presented within this
press release.
