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” and “Organic net revenue 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 impact of an acquisition as follows: (a) for an entity acquired during the current year, we present the entity’s prior year net revenue for the same period during which we owned it in the current year as impact of the acquisition in the current year; and (b) for an entity acquired in the prior year, we present the entity’s prior year net revenue for the period during which we did not own the entity in the prior year as impact of the acquisition in the current year. We calculate 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

Page 3

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: defined as Net income excluding non-operating income or expense to achieve operating income, plus depreciation and amortization, stock-based compensation, deferred acquisition consideration adjustments, and other items. Other items include restructuring costs, acquisition-related expenses, and non-recurring items.

(4) Adjusted Diluted EPS is defined as (i) Net income (loss) attributable to Stagwell Inc. common shareholders, plus net income attributable to Class C shareholders, excluding amortization expense, impairment and other losses, stock-based compensation, deferred acquisition consideration adjustments, discrete tax items, and other items, divided by (ii) (a) the per weighted average number of common shares outstanding plus (b) the weighted average number of Class C shares outstanding, (if dilutive). Other items includes restructuring costs, acquisition-related expenses, and non-recurring items, and subject to the anti-dilution rules.

(5) Free Cash Flow: defined as Adjusted EBITDA less capital expenditures, change in net working capital, cash taxes, interest, and distributions to minority interests, but excludes contingent M&A payments. 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.

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:
