MENLO PARK, Calif., January 28, 2021 — Robert Half International Inc. (NYSE symbol: RHI) today reported revenues and earnings for the fourth quarter ended December 31, 2020.

For the quarter ended December 31, 2020, net income was $94 million, or $.84 per share, on revenues of $1.304 billion. Net income for the prior year’s fourth quarter was $113 million, or $.98 per share, on revenues of $1.537 billion.

These statements may be identified by words such as “estimate”, “forecast”, “project”, “plan”, “intend”, “believe”, “expect”, “anticipate”, or variations or negatives thereof, or by similar or comparable words or phrases.

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 Sarbanes-Oxley or other regulatory compliance 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.

Under these plans, employees direct the investment of their account balances, and the Company makes cash deposits into an investment trust consistent with these directions. Changes in the Company’s deferred compensation obligations noted above are included in SG&A or, in the case of Protiviti, direct cost, while investment income is presented separately. Reclassifications have been made to prior periods’ consolidated financial statements to conform to the current presentation. These reclassifications had no impact to previously reported income before income taxes.

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: as adjusted revenue growth rates; adjusted gross margin; adjusted selling, general and administrative expense; segment income; and combined segment income.

Variations in the Company’s financial results include the impact of changes in foreign currency exchange rates, billing days, and certain intercompany adjustments. 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 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 income and amortization of intangible assets. The Company provides combined segment income because it is how the Company evaluates segment performance.

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) 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.

Intercompany Adjustments. The “As Reported” revenue growth rates are based upon reported revenues. In order to remove the fluctuations caused by the impact of certain intercompany adjustments, applicable comparative period revenues are reclassified to conform with the current period presentation.

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 9-11.
