increase over the previous quarter, and a 35% increase over 2004.
    Non-recurring revenues for the fourth quarter were $3.4 million,
consisting primarily of professional services and installation fees.
Non-recurring revenues for the year ended December 31, 2005 were $13.1
million, consisting of $12.2 million of professional services and
installation fees, and $861,000 of customer settlements. Annual
non-recurring revenues, excluding customer settlements, increased 46%
year over year.
    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), cash interest expense, cash net income (loss), 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 are
attached to this release and commence at the bottom of our condensed
consolidated statements of operations -- GAAP presentation.
    Cost of revenues were $41.7 million for the fourth quarter and
$158.4 million for the year ended December 31, 2005, representing a 2%
increase over the previous quarter, and a 16% increase over 2004 cost
of revenues. Cost of revenues, excluding depreciation, amortization,
accretion and stock-based compensation, were $25.2 million for the
fourth quarter and $95.6 million for the year ended December 31, 2005.
Cash gross margins, defined as gross profit less depreciation,
amortization, accretion and stock-based compensation, divided by
revenues, for the quarter were 59%, up from 57% the previous quarter.
Cash gross margins were 57% for 2005, up from 50% in 2004.
    Selling, general and administrative expenses were $17.3 million
for the fourth quarter. Selling, general and administrative expenses,
excluding depreciation, amortization and stock-based compensation were
$14.8 million for the fourth quarter, a 2% decrease from the previous
quarter, and $55.4 million for 2005, a 21% increase over 2004.
    The company was able to expand its IBX footprint by approximately
19% in 2005 through the acquisition of previously built-out data
centers in the Silicon Valley, Chicago and Los Angeles areas, all
scheduled to open around the first half of 2006. Equinix also acquired
the campus that houses its flagship Washington, D.C. area IBX center
for a total purchase price of $53.8 million. In fourth quarter,
Equinix completed transactions to purchase and finance its Washington,
D.C. area center, the sale and leaseback of its Los Angeles area
center, and the planned exit of its San Jose ground lease. The exit of
the San Jose ground lease resulted in the recognition of a
restructuring charge totaling $33.8 million in the quarter.
    Net loss for the fourth quarter was $32.6 million, including
stock-based compensation expense of $2.0 million, and including the
restructuring charge of $33.8 million. This represents a basic and
diluted net loss per share of $1.25 on a weighted average share count
of 26.1 million. Net loss for the year ended December 31, 2005 was
$42.6 million, or a basic and diluted net loss per share of $1.78.
Excluding the restructuring charge and stock-based compensation, the
company was net income positive for the quarter, with a non-GAAP net
income of $3.2 million, a $7.7 million improvement over the same
quarter last year and $2.6 million improvement over the previous
quarter. The company's cash net income, defined as net income (loss)
less depreciation, amortization, accretion, stock-based compensation
expense, restructuring changes and non-cash interest expense for the
quarter was $20.5 million, a 19% improvement over the previous
quarter.
    EBITDA, defined as loss from operations before depreciation,
amortization, accretion, stock-based compensation expense and
restructuring charges, was $21.8 million for the fourth quarter and
$70.1 million for the year ended December 31, 2005, an increase of 22%
over the previous quarter and up from $35.6 million in 2004, or a 60%
EBITDA flow-through rate in 2005.
    Capital expenditures in the fourth quarter were $22.9 million, of
which $8.0 million was attributed to ongoing capital expenditures and
$14.9 million was attributed to expansion capital expenditures.
Capital expenditures for the year ended December 31, 2005 were $45.4
million, of which $19.7 million was attributed to ongoing capital
expenditures and $25.7 million was attributed to expansion capital
expenditures.
    The Company generated cash from operating activities of $18.6
million for the fourth quarter as compared to $15.5 million in the
previous quarter. Cash generated from operating activities for the
year ended December 31, 2005 was $67.6 million as compared to $36.9
million in 2004. Cash used in investing activities was $65.9 million
in the fourth quarter as compared to $42.1 million in the previous
quarter. Cash used in investing activities for the year was $120.9
million, which includes the purchase of real estate properties, as
compared to $20.7 million in 2004. Adjusted free cash flow was $6.4
million in the fourth quarter and $35.2 million for the year ended
December 31, 2005. 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 December 31, 2005, the Company's cash, cash equivalents and
investments were $188.9 million, including the $30.0 million draw-down
under the Silicon Valley Bank revolving line of credit, an increase of
$80.8 million over the previous year. The draw down was repaid in full
in January 2006.

    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 $56.8 million; cost of revenues were
        $35.9 million; cost of revenues, excluding depreciation,
        amortization, accretion and stock-based compensation, were

        at its Washington, D.C. area campus to further expand its
        Washington, D.C. area Internet Business Exchange(TM) (IBX(R))
        center. Equinix also announced that it intends to expand in
        the Chicago metro area and has identified a potential site and
        commenced performing its due diligence for possible expansion.

    Business Outlook

    For the first quarter 2006, the company expects revenue to be in
the range of $63.5 to $64.5 million. Cash gross margins are expected
to be in the range of 57% to 59%. Cash selling, general and
administrative expenses are expected to approximate $15.0 million.
EBITDA is expected to be between $21.5 and $22.5 million. Net loss is
expected to range between $9.0 and $10.0 million including the impact
of approximately $10.0 million of stock-based compensation expense,
primarily related to the new stock-based compensation expensing
requirements. Net interest expense will approximate $2.0 million. The
weighted average shares outstanding will approximate 27.6 million.
Capital expenditures are expected to be approximately $30.0 to $35.0
million including between $24.0 and $27.0 million of expansion capital
expenditures.
    For the full year of 2006, revenues are expected to be in the
range of $275.0 to $285.0 million. Cash gross margins are expected to
be in the range of 57%-59%. Cash selling, general and administrative
expenses are expected to be in the range of $60.0 to $64.0 million.
EBITDA is expected to be between $95.0 and $105.0 million. Capital
expenditures for 2006 are expected to be in a range of $95.0 to $100.0
million, comprised of approximately $20.0 million of ongoing capital
expenditures and approximately $75.0 to $80.0 million of expansion
capital expenditures for the new Chicago, Los Angeles, and Silicon
Valley expansions, as well as the expansion build out in the
Washington D.C. area campus announced today. We expect our adjusted
free cash flow to be in a range of breakeven to a negative $5.0
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).

failure to receive significant revenue from customers in
recently-acquired data centers; failure to complete any financing
arrangements contemplated from time to time; competition from existing

otherwise obtain funds to repay new or outstanding indebtedness; the
loss or decline in business from our key customers and other risks
described from time to time in Equinix's filings with the Securities

    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, cash net income (loss), 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,
non-cash interest, restructuring charges and, with respect to 2004
results, the non-cash portion of loss on debt extinguishment and
conversion (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 2005 and 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 does not provide forward-looking guidance for certain
financial data, such as depreciation, amortization, accretion,
stock-based compensation (with respect to 2006), 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 and twelve months ended December
31, 2005 and 2004, presented within this press release.

(9) We define cash interest and other income (expense) as interest
    expense plus income taxes less interest income, non-cash interest
    expense and non-cash loss on debt extinguishment and conversion.
    Non-cash interest expense is comprised of amortization of debt
    discounts and debt issuance costs and non-cash interest on our
    convertible secured notes. Non-cash loss on debt extinguishment
    and conversion is comprised of the non-cash write-off of debt
    issuance costs and discounts.
