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 current period reported revenue as the impact of

Page 3

image.jpg

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 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: defined as Net income (loss) attributable to Stagwell Inc. common shareholders excluding non-operating income or expense 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 includes restructuring, certain system implementation, working capital administrative fees and acquisition-related expenses. Adjusted EBITDA for our reportable segments is reconciled to Operating Income (Loss), as Net Income (Loss) is not a relevant reportable segment financial metric.

(4) Adjusted Diluted EPS” is defined as (i) Net income (loss) attributable to Stagwell Inc. common shareholders, plus net income (loss) attributable to Class C shareholders, excluding the impact of amortization expense, impairment and other losses, stock-based compensation, deferred acquisition consideration adjustments, discrete tax items, and other items (as defined above), based on total consolidated amounts, then allocated to Stagwell Inc. common shareholders and Class C shareholders, based on their respective income allocation percentage using a normalized effective income tax rate divided by (ii) the diluted weighted average shares outstanding. The diluted weighted average shares outstanding is calculated as (a) the diluted weighted average number of common shares outstanding plus (b) the shares of 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 Net cash provided from operations less normalized capital expenditures and capitalized software. 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 in this document are based on certain key expectations and assumptions made by the Company.

FORWARD LOOKING STATEMENTS & OTHER INFORMATION 2


DEFINITIONS OF NON-GAAP FINANCIAL MEASURES 3 In addition to its reported results, Stagwell Inc. has included in this earnings presentation 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: Pro Forma Results: The Pro Forma amounts presented for each period were prepared by combining the historical standalone statements of operations for each of legacy MDC and SMG. The unaudited pro forma results are provided for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or consolidated financial condition would have been had the combination actually occurred on the date indicated, nor do they purport to project the future consolidated results of operations or consolidated financial condition for any future period or as of any future date. The Company has excluded a quantitative reconciliation of Adjusted Pro Forma EBITDA to net income under the “unreasonable efforts” exception in Item 10(e)(1)(i)(B) of Regulation S-K. 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 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 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: defined as Net income (loss) attributable to Stagwell Inc. common shareholders excluding non-operating income or expense 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 includes restructuring, certain system implementation, working capital administrative fees and acquisition-related expenses. Adjusted EBITDA for our reportable segments is reconciled to Operating Income (Loss), as Net Income (Loss) is not a relevant reportable segment financial metric. 4) Adjusted Diluted EPS” is defined as (i) Net income (loss) attributable to Stagwell Inc. common shareholders, plus net income (loss) attributable to Class C shareholders, excluding the impact of amortization expense, impairment and other losses, stock-based compensation, deferred acquisition consideration adjustments, discrete tax items, and other items (as defined above), based on total consolidated amounts, then allocated to Stagwell Inc. common shareholders and Class C shareholders, based on their respective income allocation percentage using a normalized effective income tax rate divided by (ii) the diluted weighted average shares outstanding. The diluted weighted average shares outstanding is calculated as (a) the diluted weighted average number of common shares outstanding plus (b) the shares of 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 Net cash provided from operations less normalized capital expenditures and capitalized software. Free Cash Flow Conversion is the percentage of adjusted EBITDA.. 6) Financial Guidance: The Company provides guidance on a non-GAAP basis as it cannot predict certain elements which are included in reported GAAP results. Included in this earnings presentation are tables reconciling reported Stagwell Inc. results to arrive at certain of these non-GAAP financial measures.
