THE CORPORATE EXECUTIVE BOARD REPORTS SECOND QUARTER EARNINGS OF
$0.43 PER DILUTED SHARE AND 28% REVENUE GROWTH

WASHINGTON, D.C. (July 25, 2006) — The Corporate Executive Board Company (CEB) (NASDAQ: EXBD) today announced financial results for the second quarter and six months ended June 30, 2006. Revenues for the second quarter increased 27.8% to $111.7 million from $87.4 million for the second quarter of 2005. Net income and earnings per diluted share for the second quarter were $17.8 million and $0.43, respectively.

For the first six months of 2006, revenues were $216.7 million, a 28.3% increase from $169.0 million for the first half of 2005. Net income and earnings per diluted share for the first six months of 2006 were $34.9 million and $0.85, respectively.

Effective January 2006, the Company adopted Statement of Financial Accounting Standards No. 123(R) (FAS No. 123(R)), which provides the accounting rules for share-based compensation. To present results on a comparable basis to the prior year, the Company is providing adjusted financial results, including net income and earnings per diluted share that exclude the effects of share-based compensation.

Excluding the effects of share-based compensation related to FAS No. 123(R), adjusted net income for the second quarter of 2006 increased 27.9% to $21.8 million from $17.0 million for the second quarter of 2005. Adjusted earnings per diluted share for the second quarter of 2006 increased 29.3% to $0.53 from $0.41 in 2005.

Excluding the effects of share-based compensation related to FAS No. 123(R), adjusted net income for the first six months of 2006 increased 25.6% to $42.9 million from $34.2 million for the first half of 2005. Adjusted earnings per diluted share for the first six months of 2006 increased 23.8% to $1.04 from $0.84 in 2005. A reconciliation of CEB’s reported and adjusted results is set forth in the notes to the Financial Highlights section below.

Tom Monahan, Chief Executive Officer of the Corporate Executive Board, commented, “We are very happy with our second-quarter performance and strong results for the first half of 2006. Our key growth metrics are on track with three new programs off to a great start and growth from cross-sell and new clients running above the high end of their original target ranges. The cross-sell ratio climbed to 3.83 membership programs per institution, up from 3.65 at this time last year, and new companies and institutions including Compagnie Financière Richemont S.A., Embraer- Empresa Brasileira de Aeronáutica SA, Legg Mason, Inc., Loews Corporation, Lucasfilm Ltd., Otto GmbH & Co KG and Simmons Bedding Company joined their first CEB program in the quarter. You can see the total impact of our growth metrics in our 28.7% contract value growth for the quarter.”

“Today I am also delighted to announce our 40th membership program: The Enterprise Architecture Executive Council. This program serves senior executives responsible for managing the information technology architecture at large companies. Our inaugural research agenda is focused on best practices in driving adoption of enterprise priorities, aligning business strategy with IT innovation and enabling business and IT partners to realize the cost benefits of portfolio management. As with all our new programs, the program has benefited enormously from the advice and guidance of our charter members, including senior executives from Ameriquest Mortgage Company, Lincoln Financial Group, Chevron Phillips Chemical Company LLC, Electronic Arts Inc. and Target Corporation. This is the 40th program, and the third of our planned five to six new program launches for 2006.”

The Company also announced that it has entered into a new employment agreement with James J. McGonigle,

Executive Chairman of the Board of Directors. Under the new agreement, Mr. McGonigle will continue to serve in his current position as Executive Chairman until December 31, 2006, at which point Mr. McGonigle shall become Non-Executive Chairman for a period of time to be determined by the Board of Directors. Subsequent to December 31, 2006, Mr. McGonigle also will be employed with the Company on a part-time basis through April 1, 2009. The Company also entered into a new employment agreement with Mr. Monahan covering his employment as Chief Executive Officer of the Company. The employment agreements for Mr. McGonigle and Mr. Monahan will be filed with the Securities and Exchange Commission on or about July 25, 2006.

Share Repurchase

During the six months ended June 30, 2006, the Company repurchased approximately 598,000 shares of its common stock at a total cost of approximately $58.4 million. Repurchases will continue to be made in open market and privately negotiated transactions subject to market conditions. No minimum number of shares has been fixed. The Company is funding its share repurchases with cash on hand and cash generated from operations.

Outlook for 2006

The following statements summarize the Company’s guidance for 2006.

The Company is increasing its target for annual revenue growth to a minimum of 27% accompanied by continued modest expansion in the adjusted operating margin, excluding share-based compensation under FAS No. 123(R), within the target annual range of 25 — 30%. As in the past, the operating margin may fluctuate on a quarterly basis. The Company expects a quarterly revenue distribution of approximately $118.0 million for the third quarter and $125.5 million for the fourth quarter of 2006.

For 2006, the Company expects other income of approximately $25.25 to $25.75 million, an effective income tax rate of approximately 38.5% and diluted weighted shares outstanding of approximately 41.0 — 41.5 million.

The Company is raising its guidance on GAAP annual diluted earnings per share for 2006 to $1.91. For the balance of 2006, the Company expects GAAP earnings per diluted share of $0.50 for the third quarter and $0.56 for the fourth quarter.

The Company is also raising its guidance on adjusted annual diluted earnings per share for 2006, excluding share-based compensation under FAS No. 123(R), of $2.30. For the balance of 2006, the Company expects adjusted earnings per diluted share of $0.60 for the third quarter and $0.66 for the fourth quarter, reflecting a net effect for share-based compensation of $0.10 for each quarter.

The earnings per diluted share, interest income and weighted shares outstanding guidance includes only share repurchases made as of June 30, 2006.

To supplement the Company’s consolidated financial statements presented in accordance with GAAP, CEB uses non-GAAP measures of certain components of financial performance. These non-GAAP measures include non-GAAP net income, certain expenses (including cost of services, member relations and marketing and general and administrative) and non-GAAP earnings per diluted share. CEB uses these measures of operating income, gross profit, net income and earnings per share for the three and six months ended June 30, 2006, which exclude FAS No. 123(R) share-based compensation to better understand and compare results in the current period to those in prior periods that did not include FAS No. 123(R) share-based compensation. Although these non-GAAP financial measures adjust expense and other items to exclude the accounting treatment of share-based compensation, they should not be viewed as a pro-forma presentation reflecting the elimination of the underlying share-based compensation programs, as those programs are an important element of CEB’s compensation structure and generally accepted accounting principles indicate that all forms of share-based payments should be valued and included as appropriate in results of operations. CEB discloses this information to the public to enable investors who wish to more easily assess the Company’s performance on the same basis applied by management and to ease comparison on both a GAAP and non-GAAP basis among other companies that separately identify share-based compensation expenses. Although these non-GAAP measures present financial results on the same basis as prior year’s results, they do not reflect the effects of the Company’s share-based compensation programs and therefore may not be useful in comparing CEB’s results with companies with different compensation structures. CEB’s reference to these measures should be considered in addition to results that are prepared under current accounting standards but should not be considered a substitute for results that are presented as consistent with GAAP. FAS No. 123(R) did not have a significant effect on the diluted share numbers for the three and six months ended June 30, 2006.

For the six months ended June 30, 2006 and 2005, the Company also recognized $1.9 million and $0.5 million, respectively, reflecting additional employer taxes as a result of the taxable income that our employees recognized upon the exercise of non-qualified common stock options in March 2006 and 2005, respectively. The Company has recorded such expenses in the same expense line item as other compensation paid to the relevant categories of employees as follows: Cost of services, $0.8 million and $0.3 million, Marketing and member services, $0.3 million and $0.1 million, and General and administrative, $0.8 million and $0.1 for 2006 and 2005, respectively. The additional employer taxes incurred by the Company are reflected within both the GAAP amounts as reported and the adjusted financial results presented within this press release.

(1)		In accordance with FAS No. 123(R), excess tax benefits related to share-based compensation are now classified as a cash flow from financing activities rather than as a cash flow from operating activities. The net effect of this change for the six months ended June 30, 2006 is to move $18.1 million of excess tax benefits from an operating cash flow to a cash flow from financing activities, leaving total cash flows unchanged.
