In addition, historical, current and forward-looking information about the Company’s corporate responsibility and compliance programs, including targets or goals, may not be considered material for the Securities and Exchange Commission (“SEC”) or other mandatory reporting purposes and may be based on standards for measuring progress that are still developing; on internal controls, diligence or processes that are evolving; on representations reviewed or provided by third parties; and on assumptions that are subject to change in the future. Forward-looking statements are estimates only and are based on management’s current expectations; currently available information; and current strategy, plans or forecasts, and involve certain known and unknown risks, uncertainties and assumptions that are difficult to predict, often beyond the Company’s control and are inherently uncertain. Forward-looking statements are subject to risks and uncertainties that could cause actual results and outcomes, or the timing of these results or outcomes, to differ materially from those expressed or implied in the statements.

These risks and uncertainties include, but are not limited to, the following: changes to or new interpretations of United States of America (“U.S.”) or international tax regulations; the global financial and economic situation; changes in levels of unemployment and other economic conditions in the U.S. or foreign countries where the Company does business, or in particular regions or industries; reduction in the supply of candidates for contract employment or the Company’s ability to attract candidates; the development, proliferation and adoption of artificial intelligence (“AI”) by the Company and the third parties it serves; the entry of new competitors into the marketplace or expansion by existing competitors; the ability of the Company to maintain existing client relationships and attract new clients in the context of changing economic or competitive conditions; the impact of competitive pressures, including any change in the demand for the Company’s services, or the Company’s ability to maintain its margins; the possibility of the Company incurring liability for its activities, including the activities of its engagement professionals, or for events impacting its engagement professionals 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 impact of extreme weather conditions on the Company and its candidates and clients; 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 health care or other 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, or that the Company could experience a cybersecurity breach; 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.

A summary of additional risks and uncertainties can be found in the Annual Report on Form 10-K for the year ended December 31, 2025, and in the Company’s other filings with the U.S. Securities and Exchange Commission.

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. Except as required by law, the Company undertakes no obligation to update information in this report, whether as a result of new information, future events or otherwise, and notwithstanding any historical practice of doing so.

SUMMARY OF OPERATIONS

(in thousands, except per share amounts)

SUPPLEMENTAL FINANCIAL INFORMATION

(in thousands)

(1) Service revenues for finance and accounting, administrative and customer support, and technology include intersegment revenues, which represent revenues from services provided to the Company’s Protiviti segment in connection with the Company’s blended business solutions. Intersegment revenues for each functional specialization are aggregated and then eliminated as a single line.

NON-GAAP FINANCIAL MEASURES

The financial results of Robert Half Inc. (the “Company”) are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules of the 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 expenses; adjusted operating income; and adjusted revenue growth rates.

The following measures: adjusted gross margin, adjusted selling, general and administrative expenses and adjusted operating 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.

Adjusted revenue growth rates represent year-over-year revenue growth rates after removing the impacts on reported revenues from the changes in the number of billing days and foreign currency exchange rates. The Company provides 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 impacts from the changes in billing days and foreign currency exchange rates are calculated as follows:

• Billing days impact is calculated by dividing each comparative period’s reported revenues by the number of billing days for that period to arrive at a per billing day amount. Same billing day growth rates are then calculated based on the per billing day amounts. Management calculates a global, weighted-average number of billing days for each reporting period based upon inputs from all countries and all functional specializations and segments.
• Foreign currency impact is calculated by retranslating current-period international revenues, using foreign currency exchange rates from the prior year’s comparable period.

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.

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

Billing Days. The “As Reported” revenue growth rates are based upon reported revenues. Management calculates the billing day impact by dividing each comparative period’s reported revenues by the number of billing days for that period to arrive at a per billing day amount. Same billing day growth rates are then calculated based on the per billing day amounts. Management calculates a global, weighted-average number of billing days for each reporting period based upon input from all countries and all functional specializations and segments.

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. The foreign currency impact is calculated by retranslating current-period international revenues, using foreign currency exchange rates from the prior year’s comparable period.

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 10-12.
