ROBERT HALF INTERNATIONAL INC. REPORTS RECORD REVENUES AND EARNINGS FOR THE FOURTH QUARTER OF 2004

MENLO PARK, California, January 27, 2005 – Robert Half International Inc. (NYSE symbol: RHI) today reported record revenues and earnings for the fourth quarter ended December 31, 2004.

For the quarter ended December 31, 2004, net income was $49.7 million or $.28 per share, on revenues of $754.2 million. Net income for the prior year’s fourth quarter was $4.8 million or $.03 per share, on revenues of $517.7 million.

For the year ended December 31, 2004, net income was $140.6 million or $.79 per share, on revenues of $2.7 billion. For the year ended December 31, 2003, net income was $6.4 million or $.04 per share, on revenues of $2.0 billion.

“All of our operations performed well during the quarter,” said Harold M. Messmer, Jr., chairman and CEO of Robert Half International Inc. “Overall revenues for the company rose 46 percent year over year and 7 percent sequentially, leading to record quarterly revenues and earnings.

“We estimate that 17 to 20 percent of our consolidated revenues related directly to Sarbanes-Oxley Act compliance work,” Messmer said. “The balance of our revenues reflected organic growth of more than 20 percent on a year-over-year basis. This broad-based improvement was particularly noteworthy in our Accountemps and OfficeTeam staffing divisions.”

The company’s Protiviti subsidiary, which specializes in internal audit and business and technology risk consulting, achieved sequential revenue growth in excess of 20 percent in every quarter in 2004. “Fourth-quarter revenues for Protiviti were more than triple those of the same period in 2003,” Messmer said. “Protiviti has been expanding its services steadily in areas such as forensic and fraud investigations, litigation consulting, information technology security, financial-process improvement, business continuity and enterprise-wide risk management.”

Messmer continued: “We believe there also will be ongoing demand for Sarbanes-Oxley-related initiatives. This includes remediation efforts to improve controls, annual testing to support ongoing compliance, initial efforts by non-accelerated filers, and development of long-term compliance processes and programs.”

Robert Half International management will conduct a conference call today at 5 p.m. EST to discuss the quarterly financial results. The dial-in number is 800-857-9600 (+1-773-756-4602 outside the United States) and the passcode is “Robert Half International.” A taped recording of this call will be available for replay beginning at approximately 8 p.m. EST today and ending at 8 p.m. EST on February 2, 2005.
