ROBERT HALF REPORTS SECOND-QUARTER FINANCIAL RESULTS

MENLO PARK, Calif., July 22, 2021 — Robert Half International Inc. (NYSE symbol: RHI) today reported revenues and earnings for the second quarter ended June 30, 2021.

For the quarter ended June 30, 2021, net income was $149 million, or $1.33 per share, on revenues of $1.581 billion. Net income for the prior year’s second quarter was $46 million, or $.41 per share, on revenues of $1.108 billion.

“We achieved record levels of revenues and earnings in the second quarter due to a broad-based, global acceleration in demand for our staffing and business consulting services,” said M. Keith Waddell, president and CEO of Robert Half. “We are particularly pleased with the strength of our permanent placement and Protiviti operations, which grew year-over-year revenues by 102 percent and 62 percent, respectively. Protiviti reached its 15th consecutive quarter of revenue gains with very strong growth in each of its solution areas.”

“Return on invested capital for the company was 49 percent in the second quarter,” Waddell concluded.

liability for its activities, including the activities of its contract employees, or for events impacting its contract employees on clients’ premises; the possibility that adverse publicity could impact the company’s ability to attract and retain clients and candidates; the success of the company in attracting, training, and retaining qualified management personnel and other staff employees; the company’s ability to comply with governmental regulations affecting personnel services businesses in particular or employer/employee relationships in general; whether there will be ongoing demand for Sarbanes-Oxley or other regulatory compliance services; the company’s reliance on short-term contracts for a significant percentage of its business; litigation relating to prior or current transactions or activities, including litigation that may be disclosed from time to time in the company’s SEC filings; the ability of the company to manage its international operations and comply with foreign laws and regulations; the impact of fluctuations in foreign currency exchange rates; the possibility that the additional costs the company will incur as a result of healthcare reform legislation may adversely affect the company’s profit margins or the demand for the company’s services; the possibility that the company’s computer and communications hardware and software systems could be damaged or their service interrupted; and the possibility that the company may fail to maintain adequate financial and management controls and as a result suffer errors in its financial reporting.

Additionally, with respect to Protiviti, other risks and uncertainties include the fact that future success will depend on its ability to retain employees and attract clients; there can be no assurance that there will be ongoing demand for broad based consulting, regulatory compliance, technology services, public sector or other high demand advisory services; failure to produce projected revenues could adversely affect financial results; and there is the possibility of involvement in litigation relating to prior or current transactions or activities.

Because long-term contracts are not a significant part of the company’s business, future results cannot be reliably predicted by considering past trends or extrapolating past results. The company undertakes no obligation to update information contained in this release.

ROBERT HALF INTERNATIONAL INC.

NON-GAAP FINANCIAL MEASURES

The financial results of Robert Half International Inc. (the “Company”) are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules of the U.S. Securities and Exchange Commission (“SEC”). To help readers understand the Company’s financial performance, the Company supplements its GAAP financial results with the following non-GAAP measures: adjusted gross margin; adjusted selling, general and administrative expense; segment income; combined segment income and as adjusted revenue growth rates.

The following measures: adjusted gross margin; adjusted selling, general and administrative expense; and segment income include gains and losses on investments held to fund the Company’s obligations under employee deferred compensation plans. The Company provides these measures because they are used by management to review its operational results.

Combined segment income is income before income taxes, adjusted for interest expense (income) and amortization of intangible assets. The Company provides combined segment income because it is how the Company evaluates segment performance.

Variations in the Company’s financial results include the impact of changes in foreign currency exchange rates and billing days. The Company provides “as adjusted” revenue growth calculations to remove the impact of these items. These calculations show the year-over-year revenue growth rates for the Company’s lines of business on both a reported basis and also on an as-adjusted basis for global, U.S. and international operations. This information is presented for each of the six most recent quarters. The Company has provided this data because it focuses on the Company’s revenue growth rates attributable to operating activities and aids in evaluating revenue trends over time. The Company expresses year-over-year revenue changes as calculated percentages using the same number of billing days, constant currency exchange rates, and certain intercompany adjustments.

The non-GAAP financial measures provided herein may not provide information that is directly comparable to that provided by other companies in the Company’s industry, as other companies may calculate such financial results differently. The Company’s non-GAAP financial measures are not measurements of financial performance under GAAP and should not be considered as alternatives to amounts presented in accordance with GAAP. The Company does not consider these non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial results. A reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures is provided on the following pages.

(1) Changes in the Company’s deferred compensation obligations are included in selling, general and administrative expense or, in the case of Protiviti, costs of services, while the related investment income is presented separately. The non-GAAP financial measures shown in the table above are adjusted to reclassify investment income from investments held in employee deferred compensation trusts to the same line item which includes the corresponding change in obligation. These adjustments have no impact to income before income taxes.

(1) Service revenues for Accountemps, OfficeTeam, Robert Half Technology and Robert Half Management Resources include intersegment revenues, which represent revenues from services provided to Protiviti in connection with the Company’s blended business solutions. Intersegment revenues for each line of business are aggregated and then eliminated as a single line item.

The non-GAAP financial measures included in the table above adjust for the following items:

Foreign Currency Translation. The “As Reported” revenue growth rates are based upon reported revenues, which include the impact of changes in foreign currency exchange rates. In order to calculate “Constant Currency” revenue growth rates, as reported amounts are retranslated using foreign exchange rates from the prior year’s comparable period.

Billing Days. The “As Reported” revenue growth rates are based upon reported revenues. Management calculates a global, weighted-average number of billing days for each reporting period based upon inputs from all countries and all lines of business. In order to remove the fluctuations caused by comparable periods having different billing days, the company calculates “same billing day” revenue growth rates by dividing each comparative period’s reported revenues by the calculated number of billing days for that period to arrive at a “per billing day” amount. The “same billing day” growth rates are then calculated based upon the “per billing day” amounts.

The term “As Adjusted” means that the impact of different billing days, constant currency fluctuations, and certain intercompany adjustments are removed from the revenue growth rate calculation. A reconciliation of the non-GAAP year-over-year revenue growth rates to the “As Reported” year-over-year revenue growth rates is included herein on Pages 11-13.
