WATSON WYATT WORLDWIDE REPORTS ADJUSTED EPS OF $0.84

ARLINGTON, VA, November 5, 2009 — Watson Wyatt Worldwide, Inc. (NYSE, NASDAQ: WW), a leading international human capital and financial management consulting firm, today announced financial results for the first quarter of fiscal year 2010, which ended September 30, 2009.

Revenues were $401.3 million for the quarter, a decrease of 6% (decrease of 1% constant currency) from the first quarter of fiscal 2009 revenues of $426.1 million.  Net income for the first quarter of fiscal 2010 was $29.8 million, or $0.69 per diluted share.  Net income for the quarter includes $8.4 million pretax, or $0.12 per diluted share, of transaction costs related to our pending merger with Towers Perrin, and $1.9 million pretax, or $0.03 per diluted share, of severance costs.  Adjusted net income was $36.2 million, or $0.84 per diluted share.  In the prior-year first quarter, net income was $35.2 million, or $0.82 per diluted share.  When compared to prior-year first quarter exchange rates, the strengthening of the U.S. dollar had a negative impact of $0.05 on diluted earnings per share.

“These results demonstrate our sound underlying business fundamentals and strong client relationships.  All of our segments were profitable, with particularly strong growth in our Investment Consulting and Technology and Administration Solutions segments,” said John Haley, president and chief executive officer.

“We continue to provide our clients with practical solutions for today’s toughest challenges,” said Mr. Haley.  “With our anticipated merger with Towers Perrin, we look forward to serving clients around the world with an even broader range of services and deeper pool of talent.”

Operating Highlights

·                  Benefits Group revenues (representing 56% of first-quarter revenues) were $224 million for the first quarter of fiscal 2010, a decrease of 4% (increase of 1% constant currency) from $233 million in the prior-year first quarter.  On a constant currency basis, revenues increased modestly in both retirement and health care consulting.

·                  Technology and Administration Solutions Group revenues (representing 14% of first-quarter revenues) were $55 million for the first quarter of fiscal 2010, an increase of 4% (increase of 11% constant currency) from $53 million in the prior-year first quarter.  Revenues increased in both the U.K. and the U.S. due primarily to additional revenues from several large clients.

·                  Human Capital Group revenues (representing 9% of first-quarter revenues) were $38 million for the first quarter of fiscal 2010, a decrease of 24% (decrease of 22% constant currency) from $50 million in the prior-year first quarter.  There was less demand for our services in all geographic regions.

·                  Insurance & Financial Services Group revenues (representing 6% of first-quarter revenues) were $24 million for the first quarter of fiscal 2010, a decrease of 13% (decrease of 4% constant currency) from $28 million in the prior-year first quarter.  The revenue decrease was due to less project work in Europe.

·                  Investment Consulting Group revenues (representing 11% of first-quarter revenues) were $45 million for the first quarter of fiscal 2010, an increase of 6% (increase of 17% constant currency) from $42 million in the prior-year first quarter.  The revenue increase was due to increases in implemented consulting activities and strategy projects.

Outlook for Fiscal Year 2010

For fiscal year 2010, the company is maintaining its previous guidance and expects revenues to be in the range of $1.63 billion to $1.70 billion and adjusted diluted earnings per share to be in the range of $3.50 to $3.60.  Adjusted diluted earnings per share exclude severance and merger costs.  Our foreign currency exchange rate assumptions also remain unchanged.  This guidance assumes an average exchange rate of 1.65 U.S. dollars to the British pound for fiscal year 2010 and an average rate of 1.40 U.S. dollars to the Euro for fiscal year 2010.  This guidance does not include the impact of the pending merger with Towers Perrin which is expected to close during fiscal year 2010.

For the second quarter of fiscal 2010, the company expects revenues to be in the range of $405 million to $420 million and adjusted diluted earnings per share for the quarter are expected to be in the range of $0.81 to $0.86.  Adjusted diluted earnings per share exclude severance and merger costs.  This guidance assumes an average exchange rate of 1.65 U.S. dollars to the British pound for the second quarter of fiscal 2010 and an average rate of 1.40 U.S. dollars to the Euro for the second quarter of fiscal

2

2010.  This guidance does not include the impact of the pending merger with Towers Perrin which is expected to close during fiscal year 2010.

The forecasted adjusted diluted earnings per share are based on management’s estimates for fiscal year 2010 and the second quarter of fiscal 2010.  The company expects to incur charges for severance and merger costs during those periods, and the amounts are dependent upon future events.  The company will use adjusted diluted earnings per share to evaluate its performance and believes this information is helpful to shareholders.

Conference Call

The company will host a live webcast and conference call to discuss the financial results for the first quarter of fiscal 2010.  It will be held on Thursday, November 5, 2009, beginning at 9:00 a.m. Eastern Time, and can be accessed via the Internet by going to www.watsonwyatt.com.  The replay of the webcast will be available shortly after the live call for a period of three months.  The replay will also be available for one week after the call by dialing 617-801-6888 and using confirmation number 34420570.

Non-GAAP Measures

The company prepared its condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (U.S. GAAP) and pursuant to accounting requirements of the Securities and Exchange Commission applicable to quarterly reports on Form 10-Q.  In an effort to provide investors with additional information regarding the company’s results and to provide a meaningful period-over-period comparison of financial performance, the company sometimes uses non-GAAP financial measures as defined by the Securities and Exchange Commission.  The differences between the U.S. GAAP and non-GAAP financial measures are reconciled in an attached schedule.  In presenting comparable results, the company discloses non-GAAP financial measures when it believes such measures will be useful to investors in evaluating underlying business performance.  The company uses the non-GAAP financial measures to evaluate its financial performance against internal budgets and targets.  In addition, the Company reviews its results excluding the impact of certain items, as it believes that these non-GAAP financial measures are useful for evaluating core operating results and facilitating comparison across reporting periods.  The company believes non-GAAP financial measures should be considered in addition to, and not in lieu of, U.S. GAAP financial measures.  The company’s non-GAAP financial measures may be different from non-GAAP financial measures used by other

companies.

The company’s management uses adjusted diluted earnings per share to evaluate its performance. The company has announced its intention to merge with Towers Perrin, and therefore is incurring significant transaction costs.  The company has also incurred significant amounts of severance in recent quarters due to economic conditions.  A reconciliation of net income and diluted earnings per share to adjusted net income and adjusted diluted earnings per share is as follows.
