“2021 was an extraordinary year, and we achieved record annual results.

Compared with the pre-pandemic fourth quarter of 2019, 2021 revenues were higher by 15% and net income was higher by 49%. Return on invested capital for the company was 50% in the fourth quarter.

“We begin the new year with tremendous momentum and optimism, and remain laser focused on our time-tested corporate purpose — to connect people to meaningful and exciting work and provide clients with the talent and deep subject matter expertise they need to confidently compete and grow. We are proud that our commitment to diversity, equity and inclusion efforts has earned us recent recognition, including placement on the Bloomberg Gender Equality Index and the Human Rights Campaign’s list of Best Places to Work for LGBTQ+ Equality,” Waddell concluded.

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.

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 income, net and amortization of intangible assets. The Company provides combined segment income because it is how management 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 and constant currency exchange rates.

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) 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 and constant currency fluctuations 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.
