Non-GAAP Financial Measures

In addition to its reported results, Stagwell Inc. has included in this earnings release certain financial results that the Securities and Exchange Commission ("SEC") defines as "non-GAAP Financial Measures." Management believes that such non-GAAP financial measures, when read in conjunction with the Company's reported results, can provide useful supplemental information for investors analyzing period to period comparisons of the Company's results. Such non-GAAP financial measures include the following:

(1) Organic Net Revenue: "Organic net revenue growth (decline)" reflects the year-over-year change in the Company's reported net revenue attributable to the Company's management of the entities it owns. We calculate organic net revenue growth (decline) by subtracting the net impact of acquisitions (divestitures) and the impact of foreign currency exchange fluctuations from the aggregate year-over-year increase or decrease in the Company's reported net revenue. The net impact of acquisitions (divestitures) reflects the year-over-year change in the Company's reported net revenue attributable to the impact of all individual entities that were acquired or divested in the current and prior year. We calculate the impact of an acquisition as follows: (a) for an entity acquired during the current year, we present the entity's current period reported revenue as the impact of the acquisition in the current year; and (b) for an entity acquired in the prior year, we present an amount equal to the entity's current year net revenue for the same period during which we didn't own the entity in the prior year as the impact of the acquisition in the current year. We calculate the impact of a divestiture as follows: (a) for a divestiture in the current year, we present the entity's prior year net revenue for the same period during which we no longer owned it in the current year as impact of the divestiture in the current year; and (b) for a divestiture in the prior year, we present the entity's prior year net revenue for the period during which we owned it in the prior year as impact of the divestiture in the current year. We calculate the impact of any acquisition or divestiture without adjusting for foreign currency exchange fluctuations. The impact of foreign currency exchange fluctuations reflects the year-over-year change in the Company's reported net revenue attributable to changes in foreign currency exchange rates. We calculate the impact of foreign currency exchange fluctuations for the portion of the reporting period in which we recognized revenue from a foreign entity in both the current year and the prior year. The impact is calculated as the difference between (1) reported prior period net revenue (converted to U.S. dollars at historical foreign currency exchange rates) and (2) prior period net revenue converted to U.S. dollars at current period foreign exchange rates.

(2) Net New Business: Estimate of annualized revenue for new wins less annualized revenue for losses incurred in the period.

(3) Adjusted EBITDA: is defined as Net income (loss) attributable to Stagwell Inc. common shareholders excluding non-operating income or expense, income tax expense or benefit, equity in income or loss of non-consolidated entities and net income or loss attributable to noncontrolling and redeemable noncontrolling interest holders to achieve Operating income (loss), plus depreciation and amortization, stock-based compensation, deferred acquisition consideration adjustments, impairment and other losses, and other items. Other items primarily include restructuring, certain system implementation costs, working capital administrative fees, acquisition-related expenses, and other non-recurring income and expenses. Adjusted EBITDA for our reportable segments is reconciled to Operating income (loss), as Net income (loss) is not relevant for a reportable segment financial metric.

(4) Adjusted Diluted EPS: is defined as Adjusted Net Income (loss) attributable to Stagwell Inc. common and Class C shareholders, divided by the diluted weighted average shares outstanding. Adjusted Net Income represents net income (loss) attributable to Stagwell Inc. common and Class C shareholders, excluding amortization, impairment and other losses, stock-based compensation, deferred acquisition consideration adjustments, discrete tax items, and other items (as defined above), allocated between the two share classes based on their respective income allocation percentages using a normalized effective tax rate. The diluted weighted average shares outstanding includes the diluted weighted average common shares outstanding plus Class C common stock, par value $0.00001 per share (the "Class C Common Stock") as if converted to shares of Class A Common Stock if not included because they were anti-dilutive.

(5) Free Cash Flow: defined as consolidated net cash flow from operations less cash outflow from capital expenditures and capitalized software, excluding material nonrecurring capital purchases. Free Cash Flow Conversion is the percentage of adjusted EBITDA.

Included in this earnings release are tables reconciling reported Stagwell Inc. results to arrive at certain of these non-GAAP financial measures.

This document contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Company's representatives may also make forward-looking statements orally or in writing from time to time. Statements in this document that are not historical facts, including, statements about the Company's beliefs and expectations, future financial performance, growth, and future prospects, the Company's strategy, business and economic trends and growth, technological leadership and differentiation, potential and completed acquisitions, anticipated and actual operating efficiencies and synergies and estimates of amounts for redeemable noncontrolling interests and deferred acquisition consideration, constitute forward-looking statements. Forward-looking statements, which are generally denoted by words such as "ability," "aim," "anticipate," "assume," "believe," "better," "build," "consider," "continue," "could," "depend," "develop, "drive," "enhance," "estimate," "evaluate," "expand," "expect," "focus," "forecast," "future," "grow," "guidance," "illustrative," "improve," "intend," "likely," "maintain," "may," "objective," "ongoing," "opportunity," "optimize," "outlook," "plan," "position," "possible," "potential," "probable," "project," "realize," "remain," "scenario," "seek," "should," "strategy," "sufficient," "support," "target," "will," "would" or the negative of such terms or other variations thereof and terms of similar substance used in connection with any discussion of current plans, estimates and projections are subject to change based on a number of factors, including those outlined in this section.

Forward-looking statements in this document are based on certain key expectations and assumptions made by the Company. Although the management of the Company believes that the expectations and assumptions on which such forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because the Company can give no assurance that they will prove to be correct. The material assumptions upon which such forward-looking statements are based include, among others, assumptions with respect to general business, economic and market conditions, the competitive environment, anticipated and unanticipated tax consequences and anticipated and unanticipated costs. These forward-looking statements are based on current plans, estimates and projections, and are subject to change based on a number of factors, including those outlined in this section. These forward-looking statements are subject to various risks and uncertainties, many of which are outside the Company's control. Therefore, you should not place undue reliance on such statements. Forward-looking statements speak only as of the date they are made, and the Company undertakes no obligation to update publicly any of them in light of new information or future events, if any.

Forward-looking statements involve inherent risks and uncertainties. A number of important factors could cause actual results to differ materially from those contained in any forward-looking statements. Such risk factors include, but are not limited to, the following:

• risks associated with international, national and regional unfavorable economic conditions, including the effect of changing tariffs and other trade policies, inflation and other macroeconomic factors that could affect the Company or its clients;
• demand for the Company's services, which may precipitate or exacerbate other risks and uncertainties;
• inflation and actions taken by central banks to address inflation, including changes in interest rates;
• the Company's ability to attract new clients and retain existing clients;
• the impact of a reduction in client spending and changes in client advertising, marketing and corporate communications requirements;
• financial failure of the Company's clients;
• the Company's ability to retain and attract key employees;
• the Company's ability to compete in the markets in which it operates;
• the Company's ability to achieve its cost saving initiatives;
• the Company's implementation of strategic initiatives;
• the Company's ability to remain in compliance with its debt agreements, and the Company's ability to finance its contingent payment obligations when due and payable, including but not limited to those relating to redeemable noncontrolling interests, deferred acquisition consideration and profit interests;
• the Company's ability to manage its growth effectively;
• the Company's ability to identify and complete acquisitions or other strategic transactions that complement and expand the Company's business capabilities and successfully integrate newly acquired businesses into the Company's operations, retain key employees, and realize cost savings, synergies and other related anticipated benefits within the expected time period;
• the Company's ability to identify and complete divestitures and to achieve the anticipated benefits therefrom;
• the Company's ability to develop products incorporating new technologies, including augmented reality, artificial intelligence, and virtual reality, and realize benefits from such products;
• the Company's use of artificial intelligence, including generative artificial intelligence, and its ability to realize anticipated efficiencies and other benefits from its investments in artificial intelligence and automation technologies, and changes in client demand for artificial intelligence-related services;
• adverse tax consequences for the Company, its operations and its stockholders, that may differ from the expectations of the Company, including that recent or future changes in tax laws, potential changes to corporate tax rates in the United States and disagreements with tax authorities on the Company's determinations that may result in increased tax costs;
• adverse tax consequences in connection with the business combination that formed the Company in August 2021, including the incurrence of material Canadian federal income tax (including material "emigration tax");
• the Company's ability to maintain an effective system of internal control over financial reporting, including the risk that the Company's internal controls will fail to detect misstatements in its financial statements, such as errors requiring out-of-period adjustments;
• the Company's ability to accurately forecast its future financial performance and provide accurate guidance;
• the Company's ability to protect client data from security incidents or cyberattacks;
• economic disruptions resulting from war and other economic and geopolitical tensions (such as the ongoing military conflicts in Iran and the Middle East, and between Russia and Ukraine), terrorist activities, natural disasters, public health events, and tariff and trade policies, including the resulting effects on client marketing spend in affected regions;
• stock price volatility; and
• foreign currency fluctuations.

Investors should carefully consider these risks and the additional risk factors described in more detail in our Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Form 10-K"), filed with the Securities and Exchange Commission (the "SEC") on March 13, 2026, and accessible on the SEC's website at www.sec.gov, under the caption "Risk Factors," in our subsequent Quarterly Reports on Form 10-Q and in the Company's other SEC filings.
