SAVVIS REPORTS STRONG FIRST QUARTER RESULTS

Strength in Hosting Revenue Reflects Robust Demand for Core SAVVIS Services

SAVVIS Records $125.2 Million Gain on Sale of Non-strategic Assets

ST. LOUIS, MO. – April 25, 2007 – SAVVIS, Inc. (NASDAQ: SVVS), a global leader in IT infrastructure services for business applications, announced today that its revenue for the first quarter of 2007 totaled $205.2 million. Income from operations, which included $125.2 million from the gain on the sale of non-strategic assets, was $139.0 million in the first quarter 2007, and net income was $114.5 million.

First quarter operating cash flow was $28.3 million, and cash capital expenditures were $35.8 million, of which $12.7 million was for previously-announced growth projects, including the build-out of four new data centers and SAVVIS’ next-generation network. Total cash and cash equivalents were $221.6 million at March 31, 2007.

Results for the first quarter of 2007 included a $125.2 million gain on the sale of non-strategic assets, and $3.6 million of non-recurring, colocation revenue related to the resolution of a contractual dispute that had been reserved for in 2006. Excluding the impact of these non-recurring items:

• first quarter 2007 revenue would be $201.6 million, up 12% from the same period a year ago and essentially flat compared to the prior quarter;

• gross profit, defined as total revenue less cost of revenue, would be $84.9 million, up 27% from the same period a year ago and 3% from the prior quarter, and would be 42% of current-quarter revenue;

• income from operations would be $10.1 million, compared to $3.7 million in the same period a year ago and $11.6 million in the prior quarter; and

• Adjusted EBITDA* would be $39.6 million, up 56% from the same period a year ago and 10% from the prior quarter, resulting in a 20% Adjusted EBITDA margin.

Chief Executive Officer Phil Koen said, “Our first quarter financial results reflect continued strong growth in SAVVIS’ core revenue from hosting services, with managed hosting revenue up 37% from a year ago, and 4% from last quarter. Our customers, and industry analysts, agree that SAVVIS provides a unique value proposition in offering IT infrastructure as a service. Our strong Adjusted EBITDA performance in the quarter demonstrates the success of the SAVVIS business model in generating margin improvement.”

⁽¹⁾Cost of revenue excludes depreciation, amortization, and accretion. Both cost of revenue and sales, general and administrative expenses include the effect of non-cash equity-based compensation. Total non-cash equity-based compensation in cost of revenue was $1.4 million, $1.2 million, and $0.2 million and in sales, general and administrative expenses was $6.4 million, $6.0 million, and $1.6 million for the three months ended March 31, 2007, December 31, 2006, and March 31, 2006, respectively.

Total revenue for the first quarter increased 14% from a year ago and 2% from the fourth quarter 2006. Excluding $3.6 million of non-recurring revenue reported in colocation revenue, total revenue increased 12% from a year ago and was up slightly compared to the fourth quarter 2006.

Strength in hosting revenue reflected strong customer demand for managed hosting services and re-pricing of existing colocation contracts to market rates. Managed hosting services contributed 25% of total revenue up from 20% of revenue a year ago and 24% in the fourth quarter 2006. Virtualized and utility services contributed $12.1 million of managed hosting revenue, up 152% from a year ago and 17% from the fourth quarter.

Network services revenue consists of revenue from managed IP VPN services, internet access services sold to customers using SAVVIS hosting services, and bandwidth services to wholesale

customers. Network services revenue was essentially flat in the first quarter compared to the same period last year. Compared to the fourth quarter 2006, first-quarter network services revenue declined 4%. Hosting customers continued to increase their use of SAVVIS networks for data transport, driving revenue growth, which was offset by declines in wholesale bandwidth volumes and in managed IP VPN revenue.

Other services revenue includes revenue from two sources that, as previously announced, SAVVIS expects will be eliminated in 2007: $2.4 million from Telerate, which is migrating its customers to Reuters products in 2007, and $4.1 million from the non-strategic CDN assets sold in January 2007. CDN customers are continuing to transition to the purchaser of those assets. SAVVIS’ total revenue less other services revenue for the first quarter 2007 increased 20% from the first quarter 2006 and 5% from the fourth quarter 2006.

Cost of revenue was $116.7 million, including $1.4 million of non-cash equity-based compensation costs, in the current quarter, resulting in gross profit as a percentage of total revenue, or gross margin, of 43% in the current quarter. The improvement in gross margin reflects SAVVIS’ scalable business model and ongoing cost-optimization efforts.

Sales, general, and administrative expenses (“SG&A”) for the current quarter were $53.2 million, as compared to $43.4 million for the same period last year and $53.5 million in the fourth quarter of 2006. SG&A included non-cash equity-based compensation costs for the current quarter of $6.4 million, as compared to $1.6 million for the same period last year and $6.0 million in the fourth quarter 2006. As a percentage of revenue, excluding non-cash equity-based compensation costs, SG&A was 23% in the current quarter, the same as in the first quarter 2006 and down from 24% in the fourth quarter 2006.

SAVVIS realized a gain of $125.2 million from the sale of non-strategic assets in January 2007, driving income from operations for the first quarter to $139.0 million. SAVVIS’ consolidated net income was $114.5 million in the first quarter, compared to net losses of $12.4 million in the same period last year and $6.8 million in the fourth quarter 2006.

In the first quarter of 2007, SAVVIS recorded income tax expense of $6.1 million related primarily to U.S. alternative minimum tax related to the sale of non-strategic assets. While the company utilized previously-generated Net Operating Loss (NOL) deductions in computing income-tax expense, IRS regulations limit the use of NOL deductions to 90% for U.S. alternative minimum tax purposes.

Cash Flow

Net cash provided by operating activities was $28.3 million in the first quarter. Cash capital expenditures for the quarter totaled $35.8 million, which included $12.7 million for previously-announced growth projects including the next-generation network and the build-out of four new

data centers. SAVVIS’ cash position at March 31, 2007, was $221.6 million, compared to $98.7 million at December 31, 2006, and $49.6 million at March 31, 2006.

Financial Outlook

Chief Financial Officer Jeff Von Deylen said, “This year is a transitional period for SAVVIS, as we undertake two critical growth projects: the deployment of our next-generation network and the build-out of four new data centers. The sale of non-strategic assets, completed in January, will fund a significant portion of those projects. Continued growth in our hosting revenue in the first quarter reflects our expectation that hosting will drive SAVVIS’ financial performance improvements in 2007. We’ve also achieved continued success in our ongoing margin-improvement efforts, and therefore are raising our full year guidance for Adjusted EBITDA from a range of $145-155 million to $160-170 million. Our financial and operational achievements for 2007 are building the foundation for strong revenue and Adjusted EBITDA performance in 2008.”

SAVVIS management’s current expectations for 2007 financial results include:

• Total revenue in a range of $820-835 million, including

o growth in total Hosting revenue of 27-30%,

o Network services revenue declining 3-4%, and

o Other services revenue declining to near zero by the end of the year;

• Adjusted EBITDA in a range of $160-170 million, reflecting an Adjusted EBITDA margin of approximately 20%, including

o approximately $7-9 million of negative Adjusted EBITDA impact from operating four new data centers, as operating expenses precede anticipated customer revenue; and

• Cash capital expenditures of $340-350 million, including $35-40 million for the next-generation network upgrade and approximately $200 million for the four new data centers, with approximately 60-70% of the remainder reflecting ongoing customer-growth-based investments.

o Capital expenditures for 2007 will be primarily funded by existing resources and proceeds from the January sale of non-strategic assets.

o SAVVIS anticipates bringing its four new data centers online beginning in the fourth quarter of 2007. Those data centers are expected to generate approximately $50 million of revenue in 2008 at approximately 40% Adjusted EBITDA margins.
