IntercontinentalExchange Reports Record Revenues and Net Income Attributable

to ICE; First Quarter GAAP EPS of $1.74; Adjusted EPS up 30% to $1.77

ATLANTA, GA (May 4, 2011) — IntercontinentalExchange, Inc. (NYSE: ICE), a leading operator of regulated global exchanges, clearing houses and over-the-counter (OTC) markets, today reported financial results for the first quarter of 2011. Consolidated revenues were a record $334 million, up 19% from first quarter 2010. Consolidated net income attributable to ICE was a record $129 million in the quarter, a 27% increase from first quarter 2010. Diluted earnings per share (EPS) in the first quarter grew 28% to a record $1.74.

Certain acquisition-related transaction items were included in ICE’s first quarter 2011 and 2010 GAAP operating results that management believes are not indicative of normal operating performance. Excluding these items from results, first quarter 2011 adjusted net income attributable to ICE increased 29% to $131 million and adjusted diluted EPS increased 30% to $1.77.

Said ICE Chairman and CEO Jeffrey C. Sprecher: “By focusing on the needs of our customers and opportunities in our markets, ICE continues to produce consistent financial and operating results. Our own organic growth has been enhanced by our long history of successful acquisitions. ICE’s ability to transform acquisitions into opportunities for future growth has been a defining characteristic of ICE and a major point of distinction in the exchange sector.”

ICE CFO Scott A. Hill added: “This was a great quarter for ICE — and a typical quarter, as a result of our financial discipline. We continued to execute a number of long-standing strategic initiatives, such as the expansion of our OTC products and clearing services, while also venturing into new, high-potential markets. From the launch of our BRIX partnership in Brazil to growing our global clearing services, ICE continued to pursue attractive opportunities in the first quarter of 2011.”

Consolidated revenues grew 19% in the first quarter of 2011 to $334 million. Consolidated transaction and clearing revenues were $299 million, an increase of 19% versus the prior first quarter.

Consolidated average daily volume in ICE’s futures segment in the first quarter of 2011 was 1,596,165 contracts, up 24% from the same period of 2010.

First quarter 2011 transaction and clearing revenues in ICE’s global OTC segment increased 10% to $142 million. Average daily commissions (ADC) for ICE’s OTC energy business were a record $1.6 million in the first quarter of 2011, an increase of 18% from the first quarter of 2010.

Non-GAAP Financial Measures and Reconciliation

Below we provide adjusted net income attributable to ICE and adjusted earnings per share attributable to ICE common shareholders as additional information regarding our operating results. We use these non-GAAP measures internally to evaluate our performance and in making financial and operational decisions. We believe that our presentation of these measures provides investors with greater transparency and supplemental data relating to our financial condition and results of operations. In addition, we believe the presentation of these measures is useful to investors for period-to-period comparison of results because the items described below are not part of our core business. These measures are not in accordance with, or an alternative to, U.S. generally accepted accounting principles, or GAAP, and may be different from non-GAAP measures used by other companies. Investors should not rely on any single financial measure when evaluating our business. We strongly recommend that investors review the GAAP financial measures included in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2011, including our consolidated financial statements and the notes thereto.

During the three months ended March 31, 2011 and 2010, we recognized acquisition-related transaction costs as we continue to explore and pursue acquisitions and other strategic opportunities to strengthen our competitive position and support our growth, including transactions costs relating to the potential acquisition of NYSE Euronext that we incurred during the three months ended March 31, 2011. The tax effect of these items is calculated by applying specific legal entity and jurisdictional marginal tax rates. Adjusted net income attributable to ICE for the periods presented below is calculated by adding net income attributable to ICE and the acquisition-related transaction costs, which are not part of our core business, and its related income tax effect. The following table reconciles net income attributable to ICE to adjusted net income attributable to ICE and calculates adjusted earnings per share attributable to ICE common shareholders as follows for the following periods (in thousands, except per share amounts):
