Equinix Acquires Additional Silicon Valley Center and Raises 2005 Guidance;
 Conference Call Planned to Discuss Acquisition and Increased Guidance

    FOSTER CITY, Calif.--(BUSINESS WIRE)--June 15, 2005--After opening
its third Silicon Valley data center earlier this year, Equinix, Inc.
(Nasdaq:EQIX), the leading provider of network-neutral data centers
and Internet exchange services, today announced that it has acquired a
fourth Silicon Valley center. The move will provide Equinix with
additional data center space to respond to strong customer demand in
one of Equinix's fastest growing markets. Equinix will discuss this
expansion and updated guidance for the quarter ending June 30, 2005
and for the year ending December 31, 2005 on an investor conference
call set for Thursday, June 16, 2005, at 8:00 a.m. ET (5:00 a.m. PT).
    The new 120,000 square foot Silicon Valley center was acquired
through a long-term lease commencing in October 2005. It will add
approximately 1,800 cabinets and increase Equinix's Silicon Valley
footprint to more than 500,000 square feet. The center will be
interconnected to Equinix's three other Silicon Valley centers through
redundant dark fiber links managed by Equinix, enabling new customers
in each center to have direct access to the more than 50 networks
already operating in Equinix's Silicon Valley centers, as if they were
in the same location. It will also feature a physical infrastructure
that is consistent with Equinix's industry-leading standards for
high-performance, security, environmental control and power
availability.
    The new center was originally built-out in 2001 at an estimated
cost of $80 million. Equinix intends to invest approximately $15.0
million of capital expenditures to upgrade the center to Equinix
standards, of which $4.0 to $7.0 million is expected be incurred in
2005. Equinix intends to open the new center for customers in
mid-2006.
    With more than 200 network service providers, nine of the top 10
Web properties (according to Nielsen NetRatings) and hundreds of other
companies operating within its IBX centers, Equinix's neutral,
network-rich IBX centers are widely recognized as the leading hubs for
the exchange of core Internet traffic.
    "Our current momentum, expansion opportunities and competitive
position are solidifying Equinix's market leadership position," said
Peter Van Camp, CEO of Equinix. "We continue to see attractive
opportunities to acquire additional centers in our highest growing
markets. As we pursue this, the team at Equinix believes it has the
opportunity to build an enterprise generating annual revenues of $500
million over time."
    "As a result of our second quarter momentum, we are raising
guidance for 2005 and increasing our outlook for second quarter EBITDA
results," said Renee Lanam, CFO of Equinix. "The Silicon Valley
expansion is included in this increased guidance, while other possible
expansions in 2005 are not expected to negatively impact EBITDA
guidance."
    Total revenues for 2005 are expected to be in the range of $215.0
to $219.0 million, up from previous expectations of $209.0 to $215.0
million. EBITDA for the year is expected to be between $64.0 and $68.0
million, up from previous expectations of $61.0 to 65.0 million,
including $1.0 million of operating costs associated with the Silicon
Valley expansion.
    Capital expenditures for 2005 are expected to be in a range of
$33.0 to $37.0 million, comprised of approximately $17.0 to $18.0
million of ongoing capital expenditures and approximately $16.0 to
$19.0 million of expansion capital expenditures. Free cash flow is
expected to exceed $30.0 million.
    Second quarter revenue guidance is projected to be at the high end
of the current range of $51.5 to $52.5 million. EBITDA for the quarter
is expected to increase to $15.5 to $16.5 million from previous
guidance of $14.0 to 15.0 million. Capital expenditures for the
quarter are expected to increase by $1.0 million to $10.0 to $11.0
million.
    Equinix will hold a conference call to discuss expansion strategy
and increased guidance on Thursday, June 16, 2005, at 8:00 a.m. ET
(5:00 a.m. PT). To join the conference call, please dial
1-773-799-3263 and reference the passcode (EQIX). A simultaneous live
webcast of the call will be available over the Internet at

    A replay of the call will be available beginning on Thursday, June
16, 2005 at 7:00 a.m. PT. by dialing 1-203-369-3212. In addition, the
webcast will be available on the company's Web site at

    This press release contains forward-looking statements that

from expectations discussed in such forward-looking statements.
Factors that might cause such differences include, but are not limited
to, the challenges of operating IBX centers and developing, deploying
and delivering Equinix services; a failure to receive significant
revenue from customers in recently-acquired data centers; competition
from existing and new competitors; the ability to generate sufficient
cash flow or otherwise obtain funds to repay 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
and Exchange Commission. In particular, see Equinix's recent quarterly
and annual reports filed with the Securities and Exchange Commission,

    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 cash
gross margins and EBITDA. 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. With respect to cash gross margins and
EBITDA, these non-cash or non-recurring items are depreciation,
amortization, accretion, stock-based compensation, and, with respect
to 2004 results, restructuring charges (there were no such charge 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. When Equinix reports its
historical results, it provides a reconciliation of these non-GAAP
financial measures to the most closely applicable GAAP financial
measure, including cash gross margins and EBITDA. 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, which is available on our
Web site.
