                    EXPLANATORY NOTE

On December 21, 2020, MDC Partners Inc. (“MDC”) and Stagwell Media LP (“Stagwell Media”) announced that they had entered into the Transaction Agreement, providing for the combination of MDC with the operating businesses and subsidiaries of Stagwell Media (the “Stagwell Subject Entities”). The Stagwell Subject Entities comprised Stagwell Marketing Group LLC (“Stagwell Marketing or SMG”) and its direct and indirect subsidiaries.

On August 2, 2021 (the “Closing Date”), we completed the combination of MDC and the Stagwell Subject Entities and a series of steps and related transactions (such combination and transactions, the “Transactions”). In connection with the Transactions, among other things, (i) MDC completed a series of transactions pursuant to which it emerged as a wholly owned subsidiary of the Company, converted into a Delaware limited liability company and changed its name to Midas OpCo Holdings LLC (“OpCo”); (ii) Stagwell Media contributed the equity interests of Stagwell Marketing and its direct and indirect subsidiaries to OpCo; and (iii) the Company converted into a Delaware corporation, succeeded MDC as the publicly-traded company and changed its name to Stagwell Inc.

The Transactions were treated as a reverse acquisition for financial reporting purposes, with MDC treated as the legal acquirer and Stagwell Marketing treated as the accounting acquirer. As a result of the Transactions and the change in our business and operations, under applicable accounting principles, the historical financial results of Stagwell Marketing prior to August 2, 2021 are considered our historical financial results. Accordingly, historical information presented in this Form 10-Q

2

for events occurring or periods ending before August 2, 2021 does not reflect the impact of the Transactions or the financial results of MDC and may not be comparable with historical information for events occurring or periods ending on or after August 2, 2021.

References in this Quarterly Report on Form 10-Q to Stagwell,” “we,” “us,” “our” and the “Company” refer (i) with respect to events occurring or periods ending before August 2, 2021, to Stagwell Marketing Group LLC and its direct and indirect subsidiaries and (ii) with respect to events occurring or periods ending on or after August 2, 2021, to Stagwell Inc. and its direct and indirect subsidiaries.

All dollar amounts are stated in U.S. dollars unless otherwise stated.

                Note About Forward-Looking Statements

This document contains forward-looking statements. 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, recent business and economic trends, potential acquisitions, and estimates of amounts for redeemable noncontrolling interests and deferred acquisition consideration, constitute forward-looking statements. These 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 that could affect the Company or its clients, including as a result of the novel coronavirus pandemic (“COVID-19”);

•the effects of the outbreak of COVID-19, including the measures to reduce its spread, and the impact on the economy and demand for our services, which may precipitate or exacerbate other risks and uncertainties;

•an inability to realize expected benefits of the combination of the Company’s business with MDC (the “Business Combination” and, together with the related transactions, the “Transactions”);

•adverse tax consequences in connection with the Transactions for the Company, its operations and its shareholders, that may differ from the expectations of the Company, including that future changes in tax law, potential increases to corporate tax rates in the United States and disagreements with the tax authorities on the Company’s determination of value and computations of its attributes may result in increased tax costs;

•the occurrence of material Canadian federal income tax (including material “emigration tax”) as a result of the Transactions;

•the impact of uncertainty associated with the Transactions on the Company’s businesses;

•direct or indirect costs associated with the Transactions, which could be greater than expected;

•risks associated with severe effects of international, national and regional economic conditions;

•the Company’s ability to attract new clients and retain existing clients;

•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 achieve the full amount of its stated 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 and deferred acquisition consideration;

•the successful completion and integration of acquisitions which complement and expand the Company’s business capabilities; and

•foreign currency fluctuations.

Investors should carefully consider these risk factors, other risk factors described herein, and the additional risk factors outlined in more detail in Exhibit 99.2 to our Current Report on Form 8-K, filed with the Securities and Exchange Commission (the “SEC”) on August 10, 2021, and accessible on the SEC’s website at www.sec.gov, under the caption “Risk Factors,” and in the Company’s other SEC filings.

STAGWELL INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(thousands of United States dollars, except per share amounts, unless otherwise stated)

1. Business and Basis of Presentation

Stagwell Inc. (the “Company” or “Stagwell”), incorporated under the laws of Delaware, conducts its business through its networks and their Brands ("Brands"), which provide marketing and business solutions that realize the potential of combining data and creativity. Stagwell’s strategy is to build, grow and acquire market-leading businesses that deliver the modern suite of services that marketers need to thrive in a rapidly evolving business environment.

The accompanying consolidated financial statements include the accounts of Stagwell and its subsidiaries. Stagwell has prepared the unaudited condensed consolidated interim financial statements included herein in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting interim financial information on Form 10-Q. Accordingly, the financial statements have been condensed and do not include certain information and disclosures pursuant to these rules. The preparation of financial statements in conformity with GAAP requires us to make judgments, assumptions and estimates about current and future results of operations and cash flows that affect the amounts reported and disclosed. Actual results could differ from these estimates and assumptions. The consolidated results for interim periods are not necessarily indicative of results for the full year and should be read in conjunction with the Company’s other SEC filings.

On December 21, 2020, MDC Partners Inc. (“MDC”) and Stagwell Media LP (“Stagwell Media”) announced that they had entered into the Transaction Agreement, providing for the combination of MDC with the operating businesses and subsidiaries of Stagwell Media (the “Stagwell Subject Entities”). The Stagwell Subject Entities comprised Stagwell Marketing Group LLC (“Stagwell Marketing”) and its direct and indirect subsidiaries.

On August 2, 2021, we completed the previously announced combination of MDC Partners Inc. (“MDC”) and the operating businesses and subsidiaries of Stagwell Media LP. (“Stagwell Media”) and a series related transactions (such combination and transactions, the “Transactions”). The Transactions were treated as a reverse acquisition for financial reporting purposes, with MDC treated as the legal acquirer and Stagwell Marketing Group LLC (“Stagwell Marketing or SMG”) treated as the accounting acquirer. The results of MDC are included within the Unaudited Condensed Consolidated Statements of Operations for the period beginning on the date of the acquisition through the end of the respective period presented and the results of SMG are included for the entire period presented. See Note 4 for information in connection with the acquisition of MDC.

While a recovery from the COVID-19 pandemic is underway, economic conditions will be volatile as long as COVID-19 remains a public health threat. The Company continues to monitor developments. We will continue to monitor the worldwide public health threat, government actions to combat COVID-19 and the impact such developments may have on the overall economy, our clients and operations. The impact of the pandemic and the corresponding actions are reflected in our judgments, assumptions and estimates in the preparation of the financial statements. The judgments, assumptions and estimates will be updated and could result in different results in the future depending on the continued impact of the COVID-19 pandemic.

The accompanying financial statements reflect all adjustments, consisting of normally recurring accruals, which in the opinion of management are necessary for a fair presentation, in all material respects, of the information contained therein. Intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the prior year financial information to conform to the current year presentation.

Recent Developments

On September 23, 2021, the Company provided notices of conversion to each holder of record of each of the Company’s Series 6 and Series 8 Preferred Stock. See Note 12 for additional information in connection with the conversion of the Preferred Stock to Class A Common Stock.

On October 1, 2021 (the "closing date"), the Company entered into an agreement to purchase the remaining 26.7% interest in Targeted Victory it did not previously own for a combination of cash and Class A Common Stock, up to 50% with certain exceptions, determined at the option of the Company. The agreement provides for the purchase of half of the remaining interest on the closing date and the other half on July 31, 2023 ("second purchase"). The total purchase price, which is capped at $135,000 with certain exceptions, is based on a formula taking a multiple of the two-year average of earnings that includes the year of and the year subsequent to the year of the purchase. The seller has the option to extend the measurement period for two years in connection with the second purchase.

2. Significant Accounting Policies

The Company’s significant accounting policies are summarized as follows:

Principles of Consolidation.  The accompanying consolidated financial statements include the accounts of Stagwell Inc. and its domestic and international controlled subsidiaries that are not considered variable interest entities, and variable interest entities for which the Company is the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates.  The preparation of the consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities including goodwill, intangible assets, contingent deferred acquisition consideration, redeemable noncontrolling interests, deferred tax assets, right-of-use assets and the amounts of revenue and expenses reported during the period. These estimates are evaluated on an ongoing basis and are based on historical experience, current conditions and various other assumptions believed to be reasonable under the circumstances. These estimates require the use of assumptions about future performance, which are uncertain at the time of estimation. To the extent actual results differ from the assumptions used, results of operations and cash flows could be materially affected.

Fair Value.  The Company applies the fair value measurement guidance for financial assets and liabilities that are required to be measured at fair value and for non-financial assets and liabilities that are not required to be measured at fair value on a recurring basis, including goodwill, right-of-use assets and other identifiable intangible assets. See Note 13 included herein for additional information regarding fair value measurements.

Concentration of Credit Risk.  The Company provides marketing communications services to clients who operate in most industry sectors. Credit is granted to qualified clients in the ordinary course of business. Due to the diversified nature of the Company’s client base, the Company does not believe that it is exposed to a concentration of credit risk. No client accounted for more than 10% of the Company’s consolidated accounts receivable as of September 30, 2021 or December 31, 2020. No sales to an individual client accounted for more than 10% of revenue for the three and nine months ended September 30, 2021 and 2020.

Cash and Cash Equivalents.  The Company’s cash equivalents are primarily comprised of investments in overnight interest-bearing deposits, money market instruments and other short-term investments with original maturity dates of three months or less at the time of purchase. The Company has a concentration of credit risk in that there are cash deposits in excess of federally insured amounts and international cash balances may not qualify for foreign government insurance programs. To date, the Company has not experienced any losses on cash and cash equivalents.

Allowance for Doubtful Accounts.  Trade receivables are stated at invoiced amounts less allowances for doubtful accounts. The allowances represent estimated uncollectible receivables associated with potential customer defaults usually due to customers’ potential insolvency. The allowances include amounts for certain customers where a risk of default has been specifically identified. The assessment of the likelihood of customer defaults is based on various factors, including the length of time the receivables are past due, historical experience and existing economic conditions. Allowance for doubtful accounts was $5,294 and $5,109  at September 30, 2021 and December 31, 2020, respectively.

Expenditures Billable to Clients.  Expenditures billable to clients consist principally of outside vendor costs incurred on behalf of clients when providing services that have not yet been invoiced to clients. Such amounts are invoiced to clients at various times over the course of the period.

Fixed Assets.  Fixed assets are stated at cost, net of accumulated depreciation. Computers, furniture and fixtures, and capitalized software are depreciated on a straight-line basis over periods of three to ten years. Leasehold improvements are depreciated on a straight-line basis over the lesser of the term of the related lease or the estimated useful life of the asset. Repairs and maintenance costs are expensed as incurred. Accumulated depreciation was $39,357 and $28,365 at September 30, 2021 and December 31, 2020, respectively.

Leases. Effective January 1, 2019, the Company adopted Accounting Standards Codification, Leases (“ASC 842”). The Company recognizes on the balance sheet at the time of lease commencement a right-of-use lease asset and a lease liability, initially measured at the present value of the lease payments. All right-of-use lease assets are reviewed for impairment. With the adoption of ASC 842, the Company elected to apply the package of practical expedients: (i) whether a contract is or contains a lease, (ii) the classification of existing leases, and (iii) whether previously capitalized costs continue to qualify as initial indirect costs. Additionally, the Company elected the practical expedient to not separate non-lease components from lease components for all operating leases. See Note 8 included herein for further information on leases.

14

Impairment of Long-lived Assets.  A long-lived asset or asset group is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, the Company compares the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of such asset or asset group. If this comparison indicates that there is an impairment, the amount of the impairment is typically calculated using discounted expected future cash flows where observable fair values are not readily determinable. The discount rate applied to these cash flows is based on the Company’s weighted average cost of capital (“WACC”), risk adjusted where appropriate, or other appropriate discount rate.

Goodwill.  Goodwill (the excess of the acquisition cost over the fair value of the net assets acquired) acquired as a result of a business combination which is not subject to amortization is tested for impairment, at the reporting unit level, annually as of October 1st of each year, or more frequently if indicators of potential impairment exist.

For the annual impairment test, the Company has the option of assessing qualitative factors to determine whether it is more likely than not that the carrying amount of a reporting unit exceeds its fair value or performing a quantitative goodwill impairment test. Qualitative factors considered in the assessment include industry and market considerations, the competitive environment, overall financial performance, changing cost factors such as labor costs, and other factors specific to each reporting unit such as change in management or key personnel.

If the Company elects to perform the qualitative assessment and concludes that it is more likely than not that the fair value of the reporting unit is more than its carrying amount, then goodwill is not considered impaired and the quantitative impairment test is not necessary. For reporting units for which the qualitative assessment concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount and for reporting units for which the qualitative assessment is not performed, the Company will perform the quantitative impairment test, which compares the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit exceeds the carrying amount of the net assets assigned to that reporting unit, goodwill is not considered impaired. However, if the fair value of the reporting unit is lower than the carrying amount of the net assets assigned to the reporting unit, an impairment charge is recognized equal to the excess of the carrying amount over the fair value.

Determining the fair value of a reporting unit involves the use of significant estimates and assumptions. The Company uses a combination of the income approach, which incorporates the use of the discounted cash flow (“DCF”) method, and the market approach, which incorporates the use of earnings and revenue multiples based on market data. The Company generally applies an equal weighting to the income and market approaches for the impairment test. The income approach and the market approach both require the exercise of significant judgment, including judgment about the amount and timing of expected future cash flows, assumed terminal value and appropriate discount rates.

The DCF estimates incorporate expected cash flows that represent a spectrum of the amount and timing of possible cash flows of each reporting unit from a market participant perspective. The expected cash flows are developed from the Company’s long-range planning process using projections of operating results and related cash flows based on assumed long-term growth rates, demand trends and appropriate discount rates based on a reporting unit’s WACC as determined by considering the observable WACC of comparable companies and factors specific to the reporting unit. The terminal value is estimated using a constant growth method which requires an assumption about the expected long-term growth rate. The estimates are based on historical data and experience, industry projections, economic conditions, and the Company’s expectations.

Definite Lived Intangible Assets.  Definite lived intangible assets are subject to amortization over their useful lives. A straight-line amortization method is used over the estimated useful life which is representative of the pattern of how the economic benefits of the specific intangible asset is consumed. Intangible assets that are subject to amortization are reviewed for potential impairment at least annually or whenever events or circumstances indicate that carrying amounts may not be recoverable. The Company uses an income approach, which incorporates the use of the discounted cash flow (“DCF”) method.

Business Combinations. Business combinations are accounted for using the acquisition method and accordingly, the assets acquired (including identified intangible assets), the liabilities assumed and any noncontrolling interest in the acquired business are recorded at their acquisition date fair values.

For each acquisition, the Company undertakes a detailed review to identify other intangible assets and a valuation is performed for all such identified assets. The Company uses several market participant measurements to determine the estimated value. This approach includes consideration of similar and recent transactions, as well as utilizing discounted expected cash flow methodologies. A substantial portion of the intangible assets value that the Company acquires is the specialized know-how of the workforce, which is treated as part of goodwill and is not required to be valued separately. The majority of the value of the identifiable intangible assets acquired is derived from customer relationships, including the related customer contracts, as well as tradenames and trademarks.

Deferred Acquisition Consideration. Certain acquisitions include an initial payment at the time of closing and provide for future additional contingent purchase price payments. Contingent purchase price obligations for these transactions are recorded

15

as deferred acquisition consideration liabilities on the balance sheet, at the acquisition date fair value and are remeasured at each reporting period. These liabilities are derived from the projected performance of the acquired entity. These arrangements may be dependent on future events, such as the growth rate of the earnings of the relevant subsidiary during the contractual period. At each reporting date, the Company models each business’ future performance, including revenue growth and free cash flows, to estimate the value of each deferred acquisition consideration liability. The liability is adjusted quarterly based on changes in current information affecting each subsidiary’s current operating results and the impact this information will have on future results included in the calculation of the estimated liability. These adjustments are recorded in the results of operations. In instances where such contingent payments require the sellers’ continuous employment with the Company after the transaction, they are recorded as compensation expense in the Unaudited Condensed Consolidated Statements of Operations.

Redeemable Noncontrolling Interests. Many of the Company’s acquisitions include contractual arrangements where the noncontrolling shareholders have an option to purchase, or may require the Company to purchase, such noncontrolling shareholders’ incremental ownership interests under certain circumstances. The Company typically has similar call options under the same contractual terms. The amount of consideration under these contractual arrangements is not a fixed amount, but rather is dependent upon various valuation formulas, such as the average earnings of the relevant subsidiary through the date of exercise or the growth rate of the earnings of the relevant subsidiary during that period. In the event that an incremental purchase may be required by the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity on the Unaudited Condensed Consolidated Balance Sheets at their acquisition date fair value and adjusted for changes to their estimated redemption value through Retained earnings or Paid-in capital (when at an accumulated deficit) in the Unaudited Condensed Consolidated Balance Sheets (but not less than their initial redemption value), except for foreign currency translation adjustments. These adjustments will not impact the calculation of earnings (loss) per share if the redemption values are less than the estimated fair values.

Subsidiary and Equity Investment Stock Transactions. Transactions involving the purchase, sale or issuance of interests of a subsidiary where control is maintained are recorded as a reduction in the redeemable noncontrolling interests or noncontrolling interests, as applicable. Any difference between the purchase price and noncontrolling interest is recorded to Common stock and other paid-in capital in the Unaudited Condensed Consolidated Balance Sheets. In circumstances where the purchase of shares of an equity investment results in obtaining control, the existing carrying value of the investment is remeasured to the acquisition date fair value and any gain or loss is recognized in the results of operations.

Revenue Recognition.  The Company’s revenue is recognized when control of the promised services are transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. See Note 5 included herein for additional information.

Cost of Services.  Cost of services sold primarily consists of staff costs that are directly attributable to the Company’s client engagements, as well as third-party direct costs of production and delivery of services to its clients. Cost of services sold does not include depreciation, amortization, and other office and general expenses that are not directly attributable to the Company’s client engagements.

Deferred Financing Costs.  The Company uses the effective interest method to amortize deferred financing costs and any original issue premium or discount, if applicable. The Company also uses the straight-line method, which approximates the effective interest method, to amortize the deferred financing costs on the Credit Agreement.

Income Taxes. We account for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates and laws expected to be in effect when the differences are expected to reverse. The Company records associated interest and penalties as a component of income tax expense. The Company records a valuation allowance against deferred income tax assets when management believes it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Management evaluates on a quarterly basis all available positive and negative evidence considering factors such as the reversal of deferred income tax liabilities, taxable income in eligible carryback years, projected future taxable income, the character of the income tax asset, tax planning strategies, changes in tax laws and other factors. The periodic assessment of the net carrying value of the Company’s deferred tax assets under the applicable accounting rules requires significant management judgment. A change to any of these factors could impact the estimated valuation allowance and income tax expense.

Stock-Based Compensation.  Under the fair value method, compensation cost is measured at fair value at the date of grant and is expensed over the service period, generally the award’s vesting period. The Company uses its historical volatility derived over the expected term of the award to determine the volatility factor used in determining the fair value of the award. The Company recognizes forfeitures as they occur.

Stock-based awards that are settled in cash or equity at the option of the Company are recorded at fair value on the date of grant. The fair value measurement of the compensation cost for these awards is based on using the Black-Scholes option

16

pricing-model or other acceptable method and is recorded in Operating income over the service period, in this case the award’s vesting period.

The Company has adopted the straight-line attribution method for determining the compensation cost to be recorded during each accounting period. The Company commences recording compensation expense related to awards that are based on performance conditions under the straight-line attribution method when it is probable that such performance conditions will be met.

Income (Loss) per Common Share.  Basic income (loss) per common share is based upon the weighted average number of common shares outstanding during each period. Diluted income (loss) per common share is based on the above, in addition, if dilutive, common share equivalents, which include outstanding options, stock appreciation rights, and unvested restricted stock units. In periods of net loss, all potentially issuable common shares are excluded from diluted net loss per common share because they are anti-dilutive.

Foreign Currency Translation.  The functional and reporting currency of the Company is the US dollar. Generally, the Company’s subsidiaries use their local currency as their functional currency. Accordingly, the currency impacts of the translation of the Unaudited Condensed Consolidated Balance Sheets of the Company and its non-U.S. dollar based subsidiaries to U.S. dollar statements are included as cumulative translation adjustments in Accumulated other comprehensive income (loss). Translation of intercompany debt, which is not intended to be repaid, is included in cumulative translation adjustments. Cumulative translation adjustments are not included in net income (loss) unless they are actually realized through a sale or upon complete, or substantially complete, liquidation of the Company’s net investment in the foreign operation. Translation of current intercompany balances are included in net income (loss). The balance sheets of non-U.S. dollar based subsidiaries are translated at the period end rate. The Unaudited Condensed Consolidated Statements of Operations of the Company and its non-U.S. dollar based subsidiaries are translated at average exchange rates for the period.

Gains and losses arising from the Company’s foreign currency transactions are reflected in Foreign exchange, net on the Consolidated Statements of Operations.

3. New Accounting Pronouncements

In October 2021, the FASB issued ASU 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the recognition of an acquired contract liability and other items. ASU 2021-08 is effective January 1, 2023; however, the Company has early adopted the standard and retrospectively applied it to the financial statements herein.

In March 2020, the FASB issued ASU 2020-04, and in January subsequently issued ASU 2021-01, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, to provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 is effective upon issuance, through December 31, 2022. The Company is evaluating the impact of the adoption of this guidance on the Company's financial statements and disclosures.

4. Acquisitions and Dispositions

2021 Acquisition

On December 21, 2020, MDC Partners Inc. (“MDC”) and Stagwell Media LP (“Stagwell Media”) announced that they had entered into the Transaction Agreement, providing for the combination of MDC with the operating businesses and subsidiaries of Stagwell Media (the “Stagwell Subject Entities”). The Stagwell Subject Entities comprised Stagwell Marketing Group LLC (“Stagwell Marketing or SMG”) and its direct and indirect subsidiaries.

On August 2, 2021 (the “Closing Date”), we completed the combination of MDC and the Stagwell Subject Entities and a series of steps and related transactions (such combination and transactions, the “Transactions”). In connection with the Transactions, among other things, (i) MDC completed a series of transactions pursuant to which it emerged as a wholly owned subsidiary of the Company, converted into a Delaware limited liability company and changed its name to Midas OpCo Holdings LLC (“OpCo”); (ii) Stagwell Media contributed the equity interests of Stagwell Marketing and its direct and indirect subsidiaries to OpCo; and (iii) the Company converted into a Delaware corporation, succeeded MDC as the publicly-traded company and changed its name to Stagwell Inc.

In respect of the Transactions, the acquired assets and assumed liabilities, together with acquired processes and employees, represent a business as defined in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”). The Transactions was accounted for as a reverse acquisition using the acquisition method of accounting, pursuant to FASB Topic 805-10, Business Combinations, with MDC treated as the legal

17

acquirer and SMG treated as the accounting acquirer. In identifying SMG as the acquiring entity for accounting purposes, MDC and SMG took into account a number of factors, including the relative voting rights and the corporate governance structure of the Company. SMG is considered the accounting acquirer since Stagwell Media controls the board of directors of the Company following the Transactions and received an indirect ownership interest in the Company’s only operating subsidiary, OpCo, of 69.55% ownership of OpCo’s common units. However, no single factor was the sole determinant in the overall conclusion that Stagwell is the acquirer for accounting purposes; rather all factors were considered in arriving at such conclusion. Under the acquisition method of accounting, the assets and liabilities of MDC, as the accounting acquiree, were recorded at their respective fair value as of the date the Transactions were completed.

On August 2, 2021, an aggregate of 179,970,051 shares of the Company’s Class C common stock were issued to Stagwell Media in exchange for $1,800 (the “Stagwell New MDC Contribution”). The Class C common stock does not participate in the earnings of the Company. Additionally, an aggregate of 179,970,051 OpCo common units were issued to Stagwell Media in exchange for the equity interests of the Stagwell Subject Entities (the “Stagwell OpCo Contribution”).

The fair value of the purchase consideration is $426,396, consisting of approximately 80,000,000 shares of the Company’s Class A and B common stock and common stock equivalents based on a per share price of approximately $5.42, the closing stock price on the date of the combination.

ASC 805 requires the allocation of the purchase price consideration to the fair value of the identified assets acquired and liabilities assumed upon consummation of a business combination. For this purpose, fair value shall be determined in accordance with the fair value concepts defined in ASC 820, “Fair Value Measurements and Disclosures,” (“ASC 820”). Fair value is defined in ASC 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements can be highly subjective and can involve a high degree of estimation.

The total purchase price to acquire MDC has been allocated to the assets acquired and assumed liabilities based upon preliminary estimated fair values, with any excess purchase price allocated to goodwill. The fair value of the acquired assets and assumed liabilities as of the date of acquisition are based on preliminary estimates assisted, in part, by a third-party valuation expert. The estimates are subject to change upon the finalization of appraisals and other valuation analyses, which are expected to be completed no later than one year from the date of acquisition. Although the completion of the valuation activities may result in asset and liability fair values that are different from the preliminary estimates included herein, it is not expected that those differences would alter the understanding of the impact of this transaction on the consolidated financial position and results of operations of the Company.

The preliminary purchase price allocation is as follows:

5. Revenue

The Company’s revenue recognition policies are established in accordance with ASC 606, and accordingly, revenue is recognized when control of the promised goods or services is transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

The Stagwell network provides an extensive range of services to our clients, offering a variety of marketing and communication capabilities including strategy, creative and production for advertising campaigns across a variety of platforms (print, digital, social media, television broadcast), public relations services including strategy, editorial, crisis support or issues management, media training, influencer engagement and events management. We also provide media buying and planning across a range of platforms (out-of-home, paid search, social media, lead generation, programmatic, television broadcast), experiential marketing and application/website design and development.

21

The primary source of the Company’s revenue is from agency arrangements in the form of fees for services performed, commissions, and from performance incentives or bonuses, depending on the terms of the client contract. In all circumstances, revenue is only recognized when collection is reasonably assured. Certain of the Company’s contractual arrangements have more than one performance obligation. For such arrangements, revenue is allocated to each performance obligation based on its relative stand-alone selling price. Stand-alone selling prices are determined based on the prices charged to clients or using expected cost plus margin.

The determination of our performance obligations is specific to the services included within each contract. Based on a client’s requirements within the contract, and how these services are provided, multiple services could represent separate performance obligations or be combined and considered one performance obligation. Contracts that contain services that are not significantly integrated or interdependent, and that do not significantly modify or customize each other, are considered separate performance obligations. Typically, we consider media planning, media buying, creative (or strategy), production and experiential marketing services to be separate performance obligations if included in the same contract as each of these services can be provided on a stand-alone basis, and do not significantly modify or customize each other. Public relations services and application/website design and development are typically each considered one performance obligation as there is a significant integration of these services into a combined output.

Certain of the Company’s contracts consist of a single performance obligation. In these instances, the Company does not consider the underlying activities as separate or distinct performance obligations because its services are highly interrelated, and the integration of the various components is essential to the overall promise to the Company’s customer. In certain of the Company’s client contracts, the performance obligation is a stand-ready obligation because the Company provides a constant level of similar services over the term of the contract.

We typically satisfy our performance obligations over time, as services are performed. Fees for services are typically recognized using input methods (direct labor hours, materials and third-party costs) that correspond with efforts incurred to date in relation to total estimated efforts to complete the contract. To a lesser extent, revenue is recognized using output measures, such as impressions or ongoing reporting. For client contracts when the Company has a stand-ready obligation to perform services on an ongoing basis over the life of the contract, where the scope of these arrangements includes an undefined number of broad activities and there are no significant gaps in performing the services, the Company recognizes revenue ratably using a time-based measure. In addition, for client contracts where the Company is providing online subscription-based hosted services, it recognizes revenue ratably over the contract term. Point in time recognition primarily relates to certain commission-based contracts, which are recognized upon the placement of advertisements in various media when the Company has no further performance obligation.

Revenue is recognized net of sales and other taxes due to be collected and remitted to governmental authorities. The Company’s contracts typically provide for termination by either party within 30 to 90 days. Although payment terms vary by client, they are typically within 30 to 60 days. In addition, the Company generally has the right to payment for all services provided through the end of the contract or termination date.

Within each contract, we identify whether the Company is principal or agent at the performance obligation level. In arrangements where the Company has substantive control over the service before transferring it to the client, and is primarily responsible for integrating the services into the final deliverables, we act as principal. In these arrangements, revenue is recorded at the gross amount billed. Accordingly, for these contracts the Company has included reimbursed expenses in revenue. In other arrangements where a third-party supplier, rather than the Company, is primarily responsible for the integration of services into the final deliverables, and thus the Company is solely arranging for the third-party supplier to provide these services to our client, we generally act as agent and record revenue equal to the net amount retained, when the fee or commission is earned. The role of Stagwell’s agencies under a production services agreement is to facilitate a client’s purchasing of production capabilities from a third-party production company in accordance with the client’s strategy and guidelines. The obligation of Stagwell’s agencies under media buying services is to negotiate and purchase advertising media from a third-party media vendor on behalf of a client to execute its media plan. We do not obtain control prior to transferring these services to our clients; therefore, we primarily act as agent for production and media buying services.                                    

A small portion of the Company’s contractual arrangements with clients include performance incentive provisions, which allow the Company to earn additional revenues as a result of its performance relative to both quantitative and qualitative goals. Incentive compensation is primarily estimated using the most likely amount method and is included in revenue up to the amount that is not expected to result in a reversal of a significant amount of cumulative revenue recognized. We recognize revenue related to performance incentives as we satisfy the performance obligation to which the performance incentives are related.

Disaggregated Revenue Data

The Company provides a broad range of services to a large base of clients across the full spectrum of verticals globally. The primary source of revenue is from agency arrangements in the form of fees for services performed, commissions, and from

22

performance incentives or bonuses. Certain clients may engage with the Company in various geographic locations, across multiple disciplines, and through multiple Brands. Representation of a client rarely means that Stagwell handles marketing communications for all brands or product lines of the client in every geographical location. The Company’s Brands often cooperate with one another through referrals and the sharing of both services and expertise, which enables Stagwell to service clients’ varied marketing needs by crafting custom integrated solutions. Additionally, the Company maintains separate, independent operating companies to enable it to effectively manage potential conflicts of interest by representing competing clients across the Stagwell network.

The following table presents revenue disaggregated by lines of business for the three and nine months ended September 30, 2021 and 2020:

		Three Months Ended September 30,				Nine Months Ended September 30,

Stagwell has historically largely focused where the Company was founded in North America, the largest market for its services in the world. The Company has expanded its global footprint to support clients looking for help to grow their businesses in new markets. Stagwell’s Brands are located in the United States and United Kingdom, and an additional eighteen countries around the world. In the past, some clients have responded to weakening economic conditions with reductions to their marketing budgets, which included discretionary components that are easier to reduce in the short term than other operating expenses.

The following table presents revenue disaggregated by geography for the three and nine months ended September 30, 2021 and 2020:

		Three Months Ended September 30,				Nine Months Ended September 30,

Contract Assets and Liabilities

Contract assets consist of fees and reimbursable outside vendor costs incurred on behalf of clients when providing advertising, marketing and corporate communications services that have not yet been invoiced to clients. Unbilled service fees were $137,938 and $30,570 at September 30, 2021 and December 31, 2020, respectively, and are included as a component of Accounts receivable on the Unaudited Condensed Consolidated Balance Sheets. Outside vendor costs incurred on behalf of clients which have yet to be invoiced were $37,101 and $11,063 at September 30, 2021 and December 31, 2020, respectively, and are included on the Unaudited Condensed Consolidated Balance Sheets as Expenditures billable to clients. Such amounts are invoiced to clients at various times over the course of providing services. Additions to contract assets of $99,853 were added during the period as a result of the acquisition of MDC.

Contract liabilities consist of fees billed to clients in excess of fees recognized as revenue and are classified as Advance billings and also are included within Accruals and other liabilities on the Company’s Unaudited Condensed Consolidated Balance Sheets. In arrangements in which we are acting as an agent, the revenue recognition related to the contract liability is presented on a net basis within the Unaudited Condensed Consolidated Statements of Operations. Advance billings at September 30, 2021 and December 31, 2020 were $286,790 and $66,418, respectively. The increase in the Advance billings balance of $220,372 for the nine months ended September 30, 2021 was primarily driven by the acquisition of MDC, representing a $211,687 increase, and by cash payments received or due in advance of satisfying our performance obligations, offset by $45,432 of revenues recognized that were included in the Advance billings balances as of December 31, 2020 and reductions due to the incurrence of third-party costs. Contract liabilities classified within Accruals and other liabilities at September 30, 2021 and December 31, 2020 were $168,882 and $9,311, respectively. The increase in the balance of $159,571 for the nine months ended September 30, 2021 was primarily driven by was primarily driven by the acquisition of MDC, representing a $108,488 increase, and by cash payments received or due in advance of satisfying our performance obligations, offset by $9,311 of revenues recognized that were included in the balance as of December 31, 2020 and reductions due to the incurrence of third-party costs.

Changes in the contract asset and liability balances during the nine months ended September 30, 2021 were not materially impacted by write offs, impairment losses or any other factors.

The majority of our contracts are for periods of one year or less. For those contracts with a term of more than one year, we had approximately $8,498 of unsatisfied performance obligations as of September 30, 2021, of which we expect to recognize approximately 35% in 2021, 60% in 2022 and 4% in 2023.

6. Income (Loss) Per Common Share

The following table sets forth the computations of basic and diluted income (loss) per common share:

	Three Months Ended September 30,	Nine Months Ended September 30,
	2021	2021
Numerator:
Net loss attributable to Stagwell Inc. common shareholders	$ (4,545)	$ (4,545)
Denominator:
Weighted average number of common shares outstanding	76,105,807	76,105,807
Earnings Per Share - Basic & Diluted	$ (0.06)	$ (0.06)
Anti-dilutive:
Class C shares	179,970,051	179,970,051
Stock Appreciation Rights and Restricted Awards	6,596,023	6,596,023

24

There were 123,849,000 Preferred Shares outstanding which were convertible into 33,035,446 of Class A common shares at September 30, 2021. These Preferred Shares were anti-dilutive for each period presented in the table above and are therefore excluded from the diluted earnings per share calculation.

The combination of MDC and SMG was completed on August 2, 2021, which was treated as a reverse acquisition for financial reporting purposes. SMG was treated as the accounting acquirer and MDC was the accounting acquiree. Therefore, under applicable accounting principles, the historical financial results of SMG prior to August 2, 2021 are considered our historical financial results. Accordingly, historical information presented in this Form 10-Q for events occurring or periods ending before August 2, 2021 does not reflect the impact of the Transactions or the financial results of MDC and may not be comparable with historical information for events occurring or periods ending on or after August 2, 2021.

SMG’s equity structure, prior to the combination with MDC, was a non-unitized single member limited liability company, resulting in all components of equity attributable to the member being reported within Members' Capital. Given that SMG was a non-unitized single member limited liability company, net income (loss) prior to the combination is not applicable for purposes of calculating earnings per share. Therefore, the net income (loss) in the table above includes the income or loss for the period beginning on the acquisition date through the end of the respective reporting period and as such will not reconcile to the respective amounts presented within the Unaudited Condensed Consolidated Statements of Operations.

7. Deferred Acquisition Consideration

Deferred acquisition consideration on the balance sheet consists of deferred obligations related to contingent and fixed purchase price payments, and to a lesser extent, contingent and fixed retention payments tied to continued employment of specific personnel. Contingent deferred acquisition consideration is recorded at the acquisition date fair value and adjusted at each reporting period through operating income. The Company accounts for certain retention payments through operating income as compensation expense over the required retention period.

The following table presents changes in contingent deferred acquisition consideration, which is measured at fair value on a recurring basis using significant unobservable inputs, and a reconciliation to the amounts reported on the balance sheets as of September 30, 2021 and December 31, 2020:

	September 30,		December 31,
	2021		2020
Beginning Balance of Contingent Payments	$	17,847	$	65,792
Payments	(12,286)		(66,235)
Redemption value adjustments (1)	9,535		2,520
Additions (2)	61,110		15,717
Other	(501)		53
Ending balance of contingent payments	$	75,705	$	17,847

(1) Redemption value adjustments are fair value changes from the Company’s initial estimates of deferred acquisition payments. Redemption value adjustments are recorded within Office and general expenses on the Unaudited Condensed Consolidated Statements of Operations.

(2) Additions in 2021 represent deferred acquisition consideration acquired in connection with the acquisition of MDC.

8. Leases

The Company leases office space in North America, Europe, Asia, South America, and Australia. This space is primarily used for office and administrative purposes by the Company’s employees in performing professional services. These leases are classified as operating leases and expire between years 2021 through 2034. The Company’s finance leases are immaterial.

The Company’s leasing policies are established in accordance with ASC 842, and accordingly, the Company recognizes on the balance sheet at the time of lease commencement a right-of-use lease asset and a lease liability, initially measured at the present value of the lease payments. Right-of-use lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. All right-of-use lease assets are reviewed for impairment. As the Company’s implicit rate in its leases is not readily determinable, in

25

determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the commencement date. Lease payments included in the measurement of the lease liability are comprised of noncancelable lease payments, payments based upon an index or rate, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated early.

Lease costs are recognized in the Unaudited Condensed Consolidated Statements of Operations over the lease term on a straight-line basis. Leasehold improvements are depreciated on a straight-line basis over the lesser of the term of the related lease or the estimated useful life of the asset. 

Some of the Company’s leases contain variable lease payments, including payments based upon an index or rate. Variable lease payments based upon an index or rate are initially measured using the index or rate in effect at the lease commencement date and are included within the lease liabilities. Lease liabilities are not remeasured as a result of changes in the index or rate, rather changes in these types of payments are recognized in the period in which the obligation for those payments is incurred. In addition, some of our leases contain variable payments for utilities, insurance, real estate tax, repairs and maintenance, and other variable operating expenses. Such amounts are not included in the measurement of the lease liability and are recognized in the period when the facts and circumstances which the variable lease payments are based upon occur.

Some of the Company’s leases include options to extend or renew the leases through 2044. The renewal and extension options are not included in the lease term as the Company is not reasonably certain that it will exercise its option.

From time to time, the Company enters into sublease arrangements both with unrelated third-parties and with our partner agencies. These leases are classified as operating leases and expire between years 2021 through 2031. Sublease income is recognized over the lease term on a straight-line basis. Currently, the Company subleases office space in North America, Asia, Europe and Australia.

As of September 30, 2021, the Company has entered into three operating leases for which the commencement date has not yet occurred as the premises are in the process of being prepared for occupancy by the landlord. Accordingly, these three leases represent an obligation of the Company that is not reflected within the Unaudited Condensed Consolidated Balance Sheets as of September 30, 2021. The aggregate future liability related to these leases is approximately $31,310.

The discount rate used for leases accounted for under ASC 842 is the Company’s collateralized credit adjusted borrowing rate.

The following table presents lease costs and other quantitative information for the three and nine months ended September 30, 2021 and 2020:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2021			2020			2021			2020

Interest expense related to long-term debt included in Interest expense, net on the Unaudited Condensed Consolidated Statements of Operations for the nine months ended September 30, 2021 and 2020 was $15,560 and $4,317, respectively.

The amortization of debt issuance costs included in Interest expense, net on the Unaudited Condensed Consolidated Statements of Operations for the nine months ended September 30, 2021 and 2020 was $2,092 and $396, respectively.

Revolving Credit Agreement

On November 18, 2019, the Company entered into a debt agreement (“JPM Syndicated Facility”) with a syndicate of banks led by JPMorgan Chase Bank, N.A (“JPM”). The JPM Syndicated Facility consisted of a five-year revolving credit facility of $265,000 (“JPM Revolver”) with the right to be increased by an additional $150,000. On March 18, 2020, the Company increased the commitments on the JPM Revolver by $60,000 to $325,000.

On August 2, 2021, in connection with the closing of the acquisition of MDC, the Company entered into an amended and restated credit agreement (the “Combined Credit Agreement”) with a syndicate of banks led by JPM to increase commitments on the existing JPM Revolver. The Combined Credit Agreement consists of a $500,000 senior secured revolving credit facility with a five-year maturity.

The Combined Credit Agreement contains sub-limits for revolving loans and letters of credit of $50,000 for loans denominated in pounds sterling or euros. It also includes an accordion feature under which the Company may request, subject to lender approval and certain conditions, to increase the amount of the commitments to an aggregate amount not to exceed $650,000.

Borrowings under the Combined Credit Agreement bear interest at a rate equal to, at the Company’s option, (i) the greatest of (a) the prime rate of interest announced from time to time by JPM, (b) the federal funds effective rate from time to time plus 0.50% and (c) the LIBOR rate plus 1%, in each case, plus the applicable margin (calculated based on the Company’s total leverage ratio) at that time or (ii) the LIBOR rate plus the applicable margin (calculated based on the Company’s total leverage ratio) at that time. The Company is also required to pay an unused revolver fee to the lenders under the Combined Credit Agreement in respect of the unused commitments thereunder ranging from 0.15% to 0.30% of unused commitments depending on the total leverage ratio, as well as customary letter of credit fees.

27

Advances under the Combined Credit Agreement may be prepaid in whole or in part from time to time without penalty or premium. The Combined Credit Agreement commitment may be reduced by the Company from time to time. Principal amounts outstanding under the Combined Credit Agreement are due and payable in full at maturity within five years of the date of the Combined Credit Agreement.

If an event of default occurs under the Combined Credit Agreement or any future secured indebtedness, the holders of such secured indebtedness will have a prior right to our assets securing such indebtedness, to the exclusion of the holders of the 5.625% Notes (as defined below), even if we are in default with respect to the 5.625% Notes. In that event, our assets securing such indebtedness would first be used to repay in full all indebtedness and other obligations secured by them (including all amounts outstanding under the Combined Credit Agreement), resulting in all or a portion of our assets being unavailable to satisfy the claims of the holders of the 5.625% Notes and other unsecured indebtedness.

The Combined Credit Agreement contains a number of financial and nonfinancial covenants and is guaranteed by substantially all of our present and future subsidiaries, subject to customary exceptions.

The Company was in compliance with all covenants at September 30, 2021.

A portion of the Combined Credit Agreement in an amount not to exceed $50,000 is available for the issuance of standby letters of credit. At September 30, 2021 and December 31, 2020, the Company had issued undrawn outstanding letters of credit of $25,628 and $5,500, respectively.

Term Loan

On November 13, 2020, the Company, JPM as administrative agent, and a group of lenders entered into a term loan agreement that provided the Company with a delayed draw term loan in an aggregate principal amount of $90,000 (“DD Term Loan A”) with a maturity date of November 13, 2023.

In connection with the acquisition of MDC, the Company drew down on the full amount of the DD Term Loan A, repaid the amount with the Combined Credit Agreement, and terminated the agreement.

Line of Credit

On August 2, 2021, the Company entered into an unsecured uncommitted line of credit in the aggregate amount of $30,000 with JPM (the “Line of Credit”) to meet certain short-term working capital needs. The Line of Credit expired on August 20, 2021.

Senior Notes

In August 2021, the Company issued $1,100,000 aggregate principal amount of 5.625% senior notes ("5.625% Notes"). A portion of the proceeds from the issuance of the 5.625% Notes was used to redeem $870,300 aggregate principal amount of the outstanding 7.50% Senior Notes due 2024 (the “Existing Notes”) for a price of $904,200. This price is equal to 101.625% of the outstanding principal amount of the Existing Notes being redeemed, plus, accrued, and unpaid interest on the principal amount of such Existing Notes. The Company did not recognize a gain or loss on redemption.

The 5.625% Notes are due August 15, 2029 and bear interest of 5.625% to be paid on February 15 and August 15 of each year, commencing on February 15, 2022.

The 5.625% Notes are guaranteed on a senior unsecured basis by substantially all of the Company’s subsidiaries. The 5.625% Notes rank (i) equally in right of payment with all of the Company’s or any guarantor’s existing and future unsubordinated indebtedness, (ii) senior in right of payment to the Company’s or any guarantor’s existing and future subordinated indebtedness, (iii) effectively subordinated to any of the Company’s or any guarantor’s existing and future secured indebtedness to the extent of the collateral securing such indebtedness, including the Combined Credit Agreement, and (iv) structurally subordinated to all existing and future liabilities of the Company’s subsidiaries that are not guarantors.

Our obligations under the 5.625% Notes are unsecured and are effectively junior to our secured indebtedness to the extent of the value of the collateral securing such secured indebtedness. Borrowings under the Combined Credit Agreement are secured by substantially all of the assets of the Company, and any existing and future subsidiary guarantors, including all of the capital stock of each restricted subsidiary.

The Company may, at its option, redeem the 5.625% Notes in whole at any time or in part from time to time, on and after August 15, 2024 at a redemption price of 102.813% of the principal amount thereof if redeemed during the twelve-month

28

period beginning on August 15, 2024, at a redemption price of 101.406% of the principal amount thereof if redeemed during the twelve-month period beginning on August 15, 2025 and at a redemption price of 100% of the principal amount thereof if redeemed on August 15, 2026 and thereafter. Prior to August 15, 2024, the Company may, at its option, redeem some or all of the 5.625% Notes at a price equal to 100% of the principal amount of the 5.625% Notes plus a “make whole” premium and accrued and unpaid interest. The Company may also redeem, at its option, prior to August 15, 2024, up to 40% of the 5.625% Notes with the net proceeds from one or more equity offerings at a redemption price of 105.625% of the principal amount thereof.

If the Company experiences certain kinds of changes of control (as defined in the indenture), holders of the 5.625% Notes may require the Company to repurchase any 5.625% Notes held by them at a price equal to 101% of the principal amount of the 5.625% Notes plus accrued and unpaid interest. In addition, if the Company sells assets under certain circumstances, it must offer to repurchase the 5.625% Notes at a price equal to 100% of the principal amount of the 5.625% Notes plus accrued and unpaid interest.

The indenture includes covenants that, among other things, restrict the Company’s ability and the ability of its restricted subsidiaries (as defined in the indenture) to incur or guarantee additional indebtedness; pay dividends on or redeem or repurchase the capital stock of the Company; make certain types of investments; create restrictions on the payment of dividends or other amounts from the Company’s restricted subsidiaries; sell assets; enter into transactions with affiliates; create liens; enter into sale and leaseback transactions; and consolidate or merge with or into, or sell substantially all of the Company’s assets to, another person. These covenants are subject to a number of important limitations and exceptions. The 5.625% Notes are also subject to customary events of default, including cross-payment default and cross-acceleration provisions. The Company was in compliance with all covenants at September 30, 2021.

Interest Rate Swap

The Company also owns an interest rate swap maturing April 2022 with Bank of America to convert $11,563 of its variable rate debt as of September 30, 2021 to a fixed rate of 2.7%. The fair value of the swap was $155 and $416 and is included in Accruals and other liabilities on the Unaudited Condensed Consolidated Balance Sheets as of September 30, 2021 and December 31, 2020, respectively.

10. Noncontrolling and Redeemable Noncontrolling Interests

When acquiring less than 100% ownership of an entity, the Company may enter into agreements that give the Company an option to purchase, or require the Company to purchase, the incremental ownership interests under certain circumstances. Where the option to purchase the incremental ownership is within the Company’s control, the amounts are recorded as noncontrolling interests in the equity section of the Company’s Unaudited Condensed Consolidated Balance Sheets. Where the incremental purchase may be required of the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity at their estimated acquisition date redemption value and adjusted at each reporting period for changes to their estimated redemption value through Retained earnings (but not less than their initial redemption value), except for foreign currency translation adjustments.

Changes in the Company’s ownership interests in our less than 100% owned subsidiaries during the three and nine months ended September 30, 2021 and 2020 were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Net income (loss) attributable to Stagwell Inc. common shareholders	$	(2,071)	$	17,808	$	20,199	$	34,124
Transfers from the noncontrolling interest:

Net transfers from noncontrolling interests	9,679		—		9,679		—
Change from net income (loss) attributable to Stagwell Inc. and transfers to noncontrolling interests	$	7,608	$	17,808	$	29,878	$	34,124

Redeemable Noncontrolling Interests

The following table presents changes in redeemable noncontrolling interests:

	2021		2020
Beginning Balance	$	604	$	3,603
Redemptions	(2,831)		—

Net loss attributable to redeemable noncontrolling interests	(956)		(3,126)
Other	460		—
Ending Balance	$	29,787	$	604

(1) Represents redeemable noncontrolling interests acquired in connection with the acquisition of MDC.

The noncontrolling shareholders’ ability to exercise any such option right is subject to the satisfaction of certain conditions, including conditions requiring notice in advance of exercise and specific employment termination conditions. In addition, these rights cannot be exercised prior to specified staggered exercise dates. The exercise of these rights at their earliest contractual date would result in obligations of the Company to fund the related amounts during 2021 to 2025. It is not determinable, at this time, if or when the owners of these rights will exercise all or a portion of these rights.

The redeemable noncontrolling interest of $29,787 as of September 30, 2021, consists of $14,847, assuming that the subsidiaries perform over the relevant periods at their current profit levels, $14,940 upon termination of such owner’s employment with the applicable subsidiary or death, and $0 representing the initial redemption value (required floor) recorded for certain acquisitions in excess of the amount the Company would have to pay should the Company acquire the remaining ownership interests for such subsidiaries.

These adjustments will not impact the calculation of earnings (loss) per share if the redemption values are less than the estimated fair values. There is no related impact on the Company’s income per share calculations.

11. Commitments, Contingencies, and Guarantees

Legal Proceedings. The Company’s operating entities are involved in legal proceedings of various types. While any litigation contains an element of uncertainty, the Company has no reason to believe that the outcome of such proceedings or claims will have a material adverse effect on the financial condition or results of operations of the Company.

Deferred Acquisition Consideration and Options to Purchase. See Notes 7 and 10 of the Notes included herein for information regarding potential payments associated with deferred acquisition consideration and the acquisition of noncontrolling shareholders’ ownership interest in subsidiaries.

Guarantees. Generally, the Company has indemnified the purchasers of certain assets in the event that a third party asserts a claim against the purchaser that relates to a liability retained by the Company. These types of indemnification guarantees typically extend for a number of years. Historically, the Company has not made any significant indemnification payments under such agreements and no amount has been accrued in the accompanying consolidated financial statements with respect to these indemnification guarantees. The Company continues to monitor the conditions that are subject to guarantees and indemnifications to identify whether it is probable that a loss has occurred and would recognize any such losses under any guarantees or indemnifications in the period when those losses are probable and estimable.

Commitments.  At September 30, 2021, the Company had $25,628 of undrawn letters of credit.

In the ordinary course of business, the Company may enter into long-term, non-cancellable contracts with partner associations that include revenue or profit-sharing commitments related to the provision of its services. These contracts may also include provisions that require the partner associations to meet certain performance targets prior to any obligation to the Company. As of September 30, 2021, the Company estimates its future minimum commitments under these non-cancellable agreements to be: $2,435, $10,636, $5,990, $2,098 for the remainder of 2021, 2022, 2023, and 2024, respectively.

13. Fair Value Measurements

A fair value measurement assumes a transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. The hierarchy for observable and unobservable inputs used to measure fair value into three broad levels are described below: 

•Level 1 - Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

•Level 2 - Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

•Level 3 - Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

Financial Instruments that are not Measured at Fair Value on a Recurring Basis

The following table presents certain information for our financial liability that is not measured at fair value on a recurring basis at September 30, 2021 and December 31, 2020:

	September 30, 2021		December 31, 2020
	Carrying Amount	Fair Value	Carrying Amount	Fair Value
5.625% Notes	1,100,000	1,133,891	—	—

31

Our long-term debt includes fixed rate debt. The fair value of this instrument is based on quoted market prices in markets that are not active. Therefore, this debt is classified as Level 2 within the fair value hierarchy.

Financial Instruments Measured at Fair Value on a Recurring Basis

The following table presents certain information for our financial instruments that are measured at fair value on a recurring basis at September 30, 2021 and December 31, 2020:

	September 30, 2021				December 31, 2020
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Interest Rate Swap	$	155	$	155	$	416	$	416
Call Options	—		—		360		360
Preferred Shares	—		—		12,033		12,033

The interest rate swap and call options are classified as Level 3 within the fair value hierarchy.

As of December 31, 2020, the Company owned preferred shares in a company called Finn Partners. The preferred shares had a cost basis of $10,000, accrued non-cash dividends, on a cost basis, at a rate of 6% annually. The shares were redeemable to cash in the amount of the cost-plus accrued interest at any time after February 28, 2021 or upon a liquidation event and were also were convertible to common shares of Finn Partners at any time until February 28, 2021 using a conversion ratio of 1% per $1,000 of preferred shares held including accrued dividends. The conversion feature was not bifurcated and was clearly and closely related to the host instrument, preferred shares. Management determined that the preferred shares were a debt-like financial instrument and should be accounted for as available-for-sale securities at their fair value at each reporting period. These preferred shares are considered to be a Level 3 fair value measurement since they utilize unobservable inputs for which there is little or no market data and which require the Company to develop its own assumptions.

On March 11, 2021, the Company transferred all of its ownership in the preferred shares. The Company recognized a gain of $1,200 within Gain on sale of business and other, net on the Unaudited Condensed Consolidated Statements of Operations for the nine months ended September 31, 2021 related to this transaction.

Contingent deferred acquisition consideration (Level 3 fair value measurement) is recorded at the acquisition date fair value and adjusted at each reporting period. The estimated liability is determined in accordance with models of each business' future performance, including revenue growth and free cash flows. These models are dependent upon significant assumptions, such as the growth rate of the earnings of the relevant subsidiary during the contractual period and the discount rate. These growth rates are consistent with the Company’s long-term forecasts. As of September 30, 2021, the discount rate used to measure these liabilities ranged from 3.5% to 5.1%.

As these estimates require the use of assumptions about future performance, which are uncertain at the time of estimation, the fair value measurements presented on the Unaudited Condensed Consolidated Balance Sheets are subject to material uncertainty.

See Note 7 included herein for additional information regarding contingent deferred acquisition consideration.

At September 30, 2021 and December 31, 2020, the carrying amount of the Company’s financial instruments, including cash, cash equivalents, accounts receivable and accounts payable, approximated fair value because of their short-term maturity.

Non-financial Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis

Certain non-financial assets are measured at fair value on a nonrecurring basis, primarily goodwill, intangible assets (Level 3 fair value measurement) and right-of-use lease assets (Level 2 fair value measurement). Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment. The Company did not recognize an impairment of goodwill in the three and nine months ended September 30, 2021 and 2020. The Company did recognize an impairment for intangible assets in the three and nine months ended September 30, 2021 . Refer to Note 14 for further detail.

14. Supplemental Information

Immediately following the acquisition of MDC, the Company issued 12,131 SMG unit awards, of which 6,661 were fully vested and 5,470 vest over a 6-month service period.

Stagwell Media's total 179,970,051 Class C common shares and Stagwell OpCo common units issued to it in the business combination. Class C common shares and Stagwell OpCo common units.

Immediately following the acquisition of MDC, the Company also purchased the remaining interest it did not already own in Code and Theory (8.5%) and Observatory (8.1%) and an incremental interest in Targeted Victory (13.3%).

A total of 6,930 units with a value of $37,560 were exchanged for the above interests in accordance with the business combination transaction agreement. See Note 1 for information related to the purchase of the remaining noncontrolling interest in Targeted Victory.

Impairment and Other Losses

The Company recognized a charge of $14,926 for the nine months ended September 30, 2021 primarily to reduce the carrying value of intangible assets within the Media Network reportable segment in connection with the abandonment of certain trade names as part of the rebranding of the Media Network.

15. Income Taxes

Our tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items arising in interim periods.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act includes provisions relating to delaying certain payroll tax payments, refundable payroll tax credits, net operating loss carryback periods, modifications to the net interest deduction limitations and technical corrections to the tax depreciation methods for qualified improvement property. The tax law changes in the CARES Act did not have a material impact on the Company’s income tax provision.

The Company had an income tax expense for the three months ended September 30, 2021 of $5,183 (on a pre-tax income of $13,182 resulting in an effective tax rate of 39.3%) compared to an income tax expense of $2,618 (on pre-tax income of $24,075 resulting in an effective tax rate of 10.9%) for the three months ended September 30, 2020.

The difference in the effective tax rate of 39.3% in the three months ended September 30, 2021 as compared to 10.9% in the same period in 2020 primarily results from the expansion of the group to include more tax-paying entities and proportionally less pre-tax income not subject to tax within the group, as well as non-deductible share based compensation expenses incurred during the third quarter related to the merger.

The Company had an income tax expense for the nine months ended September 30, 2021 of $9,205 (on a pre-tax income of $40,466 resulting in an effective tax rate of 22.7%) compared to income tax expense of $3,211 (on pre-tax income of $41,964 resulting in an effective tax rate of 7.7%) for the nine months ended September 30, 2020.

The difference in the effective tax rate of 22.7% in the nine months ended September 30, 2021 as compared to 7.7% in the same period in 2020 primarily results from the expansion of the group to include more tax-paying entities and proportionally less pre-tax income not subject to tax within the group, as well as non-deductible share based compensation expenses incurred during the third quarter related to the merger.

The significant change of our deferred tax liability balance of $16,050 to $134,288 from December 31, 2020 to September 30, 2021, respectively, was primarily due to adjustments related to the reverse merger.

The Company determines an operating segment if a component (i) engages in business activities from which it earns revenues and incurs expenses, (ii) has discrete financial information, and is (iii) regularly reviewed by the Chief Operating Decision Maker (“CODM”), who is Mark Penn, Chief Executive Officer and Chairman, to make decisions regarding resource allocation for the segment and assess its performance. Once operating segments are identified, the Company performs an analysis to determine if aggregation of operating segments is applicable. This determination is based upon a quantitative analysis of the expected and historic average long-term profitability for each operating segment, together with a qualitative assessment to determine if operating segments have similar operating characteristics.

The CODM uses Adjusted EBITDA (defined below) as a key metric, to evaluate the operating and financial performance of a segment, identify trends affecting the segments, develop projections and make strategic business decisions. Adjusted EBITDA is 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.

The Company has three reportable segments as follows: “Integrated Agencies Network,” “Media Network” and the “Communications Network.” In addition, the Company combines and discloses operating segments that do not meet the

34

aggregation criteria as “All Other.” The Company also reports corporate expenses, as further detailed below, as “Corporate.” All segments follow the same basis of presentation and accounting policies as those described throughout the Notes to the Unaudited Condensed Consolidated Financial Statements included herein.

•The Integrated Agencies Network reportable segment is comprised of Constellation (72andSunny, Crispin Porter Bogusky, Instrument, Team Enterprises, Harris, and Redscout brands), the Anomaly Alliance (Anomaly, Concentric, Hunter, Mono, YML and Scout brands), the Doner Partner Network (Doner, 6 Degrees, KWT Global, Union, Bruce Mau Design, Vitro, Harris X, Northstar, Veritas and Yamamoto brands) and the Code & Theory Network (Code & Theory, Forsman & Bodenfors, National Research Group, Observatory, Hello Design, and Colle McVoy brands) operating segments.

The Integrated Agencies Networks provide a range of services for their clients, primarily including strategy, creative         and production for advertising campaigns across a variety of platforms (digital, social media, television broadcast and print) as well as public relations and communications services, experiential, social media and influencer marketing. These operating segments share similar characteristics related to (i) the nature of their services; (ii) the type of clients and the methods used to provide services; and (iii) the extent to which they may be impacted by global economic and geopolitical risks. In addition, these operating segments compete with each other for new business and from time to time have business move between them.

•The Media Network reportable segment is comprised of a single operating segment that combines media buying and planning across a range of platforms (out-of-home, paid search, social media, lead generation, programmatic, television broadcast) with technology and data capabilities and includes the Assembly, GALE, MMI Agency, Ink, Multiview, and Kenna brands.

•The Communications Network reportable segment is comprised of a single operating segment that provides advocacy, corporate communications, public relations and other services and includes SKDK, Allison & Partners, and Targeted Victory brands.

•All Other consists of the Company’s our central innovations group, Reputation Defender (sold in September 2021) and infancy stage digital products such as Prophet.

•Corporate consists of corporate office expenses incurred in connection with the strategic resources provided to the operating segments, as well as certain other centrally managed expenses that are not fully allocated to the operating segments. These office and general expenses include (i) salaries and related expenses for corporate office employees, including employees dedicated to supporting the operating segments, (ii) occupancy expenses relating to properties occupied by all corporate office employees, (iii) other office and general expenses including professional fees for the financial statement audits and other public company costs, and (iv) certain other professional fees managed by the corporate office. Additional expenses managed by the corporate office that are directly related to the operating segments are allocated to the appropriate reportable segment and the All Other category.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis are based on and should be read in conjunction with our unaudited condensed consolidated financial statements and the notes related thereto included elsewhere in this Current Report on Form 10-Q. The following discussion and analysis contains forward-looking statements and should be read in conjunction with the disclosures and information contained and referenced under the captions “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors” in this Quarterly Report on Form 10-Q (this “Form 10-Q”). The following discussion and analysis also includes a discussion of certain non-GAAP financial measures. A description of the non-GAAP measures discussed in this section and reconciliations to the comparable GAAP measures are below.

In this section, the terms “Stagwell,” “we,” “us,” “our” and the “Company” refer (i) with respect to events occurring or periods ending before August 2, 2021, to Stagwell Marketing Group LLC and its direct and indirect subsidiaries and (ii) with respect to events occurring or periods ending on or after August 2, 2021, to Stagwell Inc. and its direct and indirect subsidiaries.

37

References to a “fiscal year” mean the Company’s year commencing on January 1 of that year and ending December 31 of that year (e.g., fiscal 2021 means the period beginning January 1, 2021, and ending December 31, 2021).

Executive Summary

Business Combination

On December 21, 2020, MDC Partners Inc. (“MDC”) and Stagwell Media LP (“Stagwell Media”) announced that they had entered into the Transaction Agreement, providing for the combination of MDC with the operating businesses and subsidiaries of Stagwell Media (the “Stagwell Subject Entities”). The Stagwell Subject Entities comprised Stagwell Marketing Group LLC (“Stagwell Marketing or SMG”) and its direct and indirect subsidiaries.

On August 2, 2021 (the “Closing Date”), we completed the previously announced combination of MDC and the Stagwell Subject Entities and a series of steps and related transactions (such combination transactions, the “Transactions”). In connection with the Transactions, among other things, (i) MDC completed a series of transactions pursuant to which it emerged as a wholly owned subsidiary of the Company, converted into a Delaware limited liability company and changed its name to Midas OpCo Holdings LLC (“OpCo”); (ii) Stagwell Media contributed the equity interests of Stagwell Marketing and its direct and indirect subsidiaries to OpCo; and (iii) the Company converted into a Delaware corporation, succeeded MDC as the publicly-traded company and changed its name to Stagwell Inc.

The Transactions were treated as a reverse acquisition for financial reporting purposes, with MDC treated as the legal acquirer and Stagwell Marketing treated as the accounting acquirer. As a result of the Transactions and the change in our business and operations, under applicable accounting principles, the historical financial results of Stagwell Marketing prior to August 2, 2021 are considered our historical financial results. Accordingly, historical information presented in this Form 10-Q for events occurring or periods ending before August 2, 2021 does not reflect the impact of the Transactions and may not be comparable with historical information for events occurring or periods ending on or after August 2, 2021, which do not include the financial results of MDC. See Note 4 of the Unaudited Condensed Consolidated Financial Statements for additional information in connection with the Transaction.

Overview

Stagwell conducts its business through its networks, which provide marketing and business solutions that realize the potential of combining data and creativity. Stagwell’s strategy is to build, grow and acquire market-leading businesses that deliver the modern suite of services that marketers need to thrive in a rapidly evolving business environment. Stagwell’s differentiation lies in its creative roots and proven entrepreneurial leaders, which together with innovations in technology and data, bring transformational marketing, activation, communications and strategic consulting services to clients. Stagwell leverages its range of services in an integrated manner, offering strategic, creative and innovative solutions that are technologically forward and media-agnostic. The Company’s work is designed to challenge the industry status quo, realize outsized returns on investment, and drive transformative growth and business performance for its clients and stakeholders.

Stagwell manages its business by monitoring several financial and non-financial performance indicators. The key indicators that we focus on are revenue, operating expenses, capital expenditures and non-GAAP measures described below. Revenue growth is analyzed by reviewing a mix of measurements, including (i) growth by major geographic location, (ii) growth by client industry vertical, (iii) growth from existing clients and the addition of new clients, (iv) growth by primary discipline, (v) growth from currency changes, and (vi) growth from acquisitions. In addition to monitoring the foregoing financial indicators, the Company assesses and monitors several non-financial performance indicators relating to the business performance of our networks. These indicators may include a networks recent new client win/loss record; the depth and scope of a pipeline of potential new client account activity; the overall quality of the services provided to clients; and the relative strength of the Network's next generation team that is in place as part of a potential succession plan to succeed the current senior executive team.

While a recovery from the COVID-19 pandemic is underway, economic conditions will be volatile as long as COVID-19 remains a public health threat. The Company continues to monitor developments, We will continue to monitor the worldwide public health threat, government actions to combat COVID-19 and the impact such developments may have on the overall economy, our clients and operations. If the impact of the pandemic continues to go beyond expectations, the Company believes it is well positioned through the actions implemented at the onset of the pandemic to successfully work through the effects of COVID-19 on our business. The impact of the pandemic and the corresponding actions are reflected in our judgments, assumptions and estimates in the preparation of the financial statements. The judgments, assumptions and estimates will be updated and could result in different results in the future depending on the continued impact of the COVID-19 pandemic.

Recent Developments

On October 1, 2021 (the "closing date"), the Company entered into an agreement to purchase the remaining 26.7% interest in Targeted Victory it did not previously own for a combination of cash and Class A Common shares, up to 50% with certain exceptions, determined at the option of the Company. The agreement provides for the purchase of half of the remaining interest on the closing date and the other half on July 31, 2023 ("second purchase"). The total purchase price, which is capped at $135 million with certain exceptions, is based on a formula taking a multiple of the two-year average of earnings that includes the year of and the year subsequent to the year of the purchase. The seller has the option to extend the measurement period for two years in connection with the second purchase.

On September 23, 2021, the Company provided notices of conversion to each holder of record of each of the Company’s Series 6 and Series 8 Preferred Stock. See Note 12 of the Unaudited Condensed Consolidated Financial Statements for additional information in connection with the conversion of the Preferred Stock to Class A Common Shares.

Significant Factors Affecting our Business and Results of Operations

The most significant factors affecting our business and results of operations include national, regional, and local economic conditions, our clients’ profitability, mergers and acquisitions of our clients, changes in top management of our clients and our ability to retain and attract key employees. New business wins and client losses occur due to a variety of factors. The two most significant factors are (i) our clients’ desire to change marketing communication firms, and (ii) the digital and data-driven products that our Brands offer. A client may choose to change marketing communication firms for several reasons, such as a change in leadership where new management wants to retain an agency that it may have previously worked with. In addition, if the client is merged or acquired by another company, the marketing communication firm is often changed. Clients also change firms as a result of the firm’s failure to meet marketing performance targets or other expectations in client service delivery.

Seasonality

Historically, we typically generate the highest quarterly revenue during the fourth quarter in each year with a significant increase during the even years. The highest volumes of retail related consumer marketing increase with the back-to-school season through the end of the holiday season. The even years benefit from the U.S. election cycles.

Non-GAAP Measures

The Company reports its financial results in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In addition, the Company has included non-GAAP financial measures and ratios, which management uses to operate the business, which it believes provide useful supplemental information to both management and readers of this report in making period-to-period comparisons in measuring the financial performance and financial condition of the Company. These measures do not have a standardized meaning prescribed by GAAP and should not be construed as an alternative to other titled measures determined in accordance with GAAP. The non-GAAP measures included are “organic revenue growth or decline” and “Adjusted EBITDA.”

Organic Revenue: “Organic revenue growth” and “organic revenue decline” refer to the positive or negative results, respectively, of subtracting both the foreign exchange and acquisition (disposition) components from total revenue growth. The acquisition (disposition) component is calculated by aggregating prior period revenue for any acquired businesses, less the prior period revenue of any businesses that were disposed of during the current period. The organic revenue growth (decline) component reflects the constant currency impact of (a) the change in revenue of the partner firms that the Company has held throughout each of the comparable periods presented, and (b) “non-GAAP acquisitions (dispositions), net”. Non-GAAP acquisitions (dispositions), net consists of (i) for acquisitions during the current year, the revenue effect from such acquisition as if the acquisition had been owned during the equivalent period in the prior year and (ii) for acquisitions during the previous year, the revenue effect from such acquisitions as if they had been owned during that entire year (or same period as the current reportable period), taking into account their respective pre-acquisition revenues for the applicable periods, and (iii) for dispositions, the revenue effect from such disposition as if they had been disposed of during the equivalent period in the prior year.

Adjusted EBITDA is 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, and other items. Other items include restructuring costs, acquisition-related expenses, and non-recurring items.

All amounts are in dollars unless otherwise stated. Amounts reported in millions herein are computed based on the amounts in thousands. As a result, the sum of the components, and related calculations, reported in millions may not equal the total amounts due to rounding.

39

The percentage changes included in the tables herein Item 2 that are not considered meaningful are presented as “NM.”

Segments

The Company determines an operating segment if a component (i) engages in business activities from which it earns revenues and incurs expenses, (ii) has discrete financial information, and is (iii) regularly reviewed by the Chief Operating Decision Maker (“CODM”), who is Mark Penn, Chief Executive Officer and Chairman, to make decisions regarding resource allocation for the segment and assess its performance. Once operating segments are identified, the Company performs an analysis to determine if aggregation of operating segments is applicable. This determination is based upon a quantitative analysis of the expected and historic average long-term profitability for each operating segment, together with a qualitative assessment to determine if operating segments have similar operating characteristics.

The CODM uses Adjusted EBITDA as a key metric, to evaluate the operating and financial performance of a segment, identify trends affecting the segments, develop projections and make strategic business decisions.

The Company has three reportable segments as follows: “Integrated Agencies Network,” “Media Network” and the “Communications Network.” In addition, the Company combines and discloses operating segments that do not meet the aggregation criteria as “All Other.” The Company also reports corporate expenses, as further detailed below, as “Corporate.” All segments follow the same basis of presentation and accounting policies. See Note 2 of the Notes to the Unaudited Condensed Consolidated Financial Statements for the Company's significant accounting policies.

In addition, Stagwell reports its corporate office expenses incurred in connection with the strategic resources provided to the networks, as well as certain other centrally managed expenses that are not fully allocated to the operating segments as Corporate. Corporate provides client and business development support to the networks as well as certain strategic resources, including accounting, administrative, financial, real estate, human resource and legal functions.

The following discussion focuses on the operating performance of the Company for the three and nine months ended September 30, 2021 and 2020 and the financial condition of the Company as of September 30, 2021.

The increase in organic net revenue was primarily attributable to increased spending by clients in connection with the recovery from the COVID-19 pandemic and the impact from the acquisition of MDC.

The increase in expenses was driven by the impact from the acquisition of MDC. Stock-based compensation expense increased, driven by awards issued in connection with the acquisition of MDC and depreciation and amortization grew due to the recognition of amortizable intangible assets in connection with the acquisition of MDC.

Operating income increased as the increase in revenue, more than offset higher operating expenses.

The increase in Adjusted EBITDA was driven by higher revenue, partially offset by higher expenses.

Liquidity and Capital Resources:

Liquidity

The following table provides summary information about the Company’s liquidity position:

	September 30, 2021		September 30, 2020
	(Dollars in Thousands)
Net cash provided by operating activities	$	20,146	$	93,184
Net cash provided by (used in) investing activities	$	153,721	$	(16,421)
Net cash used in financing activities	$	(151,860)	$	(43,700)

We continue to monitor the worldwide public health threat, government actions to combat COVID-19 and the impact such developments may have on our liquidity. If the impact of the pandemic is beyond our expectation, the Company believes it is well positioned through the actions implemented at the beginning of the pandemic to successfully work through the effects of COVID-19 for the foreseeable future.

58

The Company had cash and cash equivalents of $115.5 million and $92.5 million as of September 30, 2021 and December 31, 2020, respectively. The Company intends to maintain sufficient cash and/or available borrowings to fund operations for the next twelve months. The Company has historically been able to maintain and expand its business using cash generated from operating activities, funds available under its revolving credit agreement, and other initiatives, such as obtaining additional debt and equity financing. At September 30, 2021, the Company had $181.1 million of borrowings outstanding and $292.8 million available under the revolving credit agreement.

The Company’s obligations extending beyond twelve months primarily consist of deferred acquisition payments, purchases of noncontrolling interests, capital expenditures, scheduled lease obligation payments, and interest payments on borrowings under the Company’s 5.625% Notes. Based on the current outlook, the Company believes future cash flows from operations, together with the Company’s existing cash balance and availability of funds under the Company’s revolving credit agreement, will be sufficient to meet the Company’s anticipated cash needs for the next twelve months. The Company’s ability to make scheduled deferred acquisition payments, principal and interest payments, to refinance indebtedness or to fund planned capital expenditures will depend on future performance, which is subject to general economic conditions, the competitive environment and other factors, including those described in this form 10-Q and in the Company’s other SEC filings.

Cash Flows

Operating Activities

Cash flows provided by operating activities for the nine months ended September 30, 2021 were $20.1 million, primarily reflecting earnings, partially offset by unfavorable working capital requirements.

Cash flows provided by operating activities for the nine months ended September 30, 2020 were $93.2 million, primarily reflecting earnings and favorable working capital requirements.

Investing Activities

During the nine months ended September 30, 2021, cash flows provided by investing activities were $153.7 million, which was primarily driven by $130.2 million of MDC cash in connection with the combination, $37.2 million from the sale of Reputation Defender, partially offset by capital expenditures of $13.7 million.

During the nine months ended September 30, 2020, cash flows used in investing activities were $16.4 million, which primarily consisted of $9.0 million of capital expenditures and $5.5 million for acquisitions.

Financing Activities

During the nine months ended September 30, 2021, cash flows used in financing activities were $151.9 million, which primarily consisted of $884.4 million for the in repurchase of the 7.50% Notes, $127.1 million in net repayments under the revolving credit agreement, $19.2 million in distributions to minority interest holders, as well as distributions of $204.9 million to Stagwell Media, offset by receipt of $1.1 billion from the issuance of the 5.625% Notes.

During the nine months ended September 30, 2020, cash flows used in financing activities was $43.7 million, primarily driven by $58.3 million in net borrowings under the revolving credit agreement, more than offset by distributions of $98.6 million to Stagwell Media.

Total Debt

Debt, net of debt issuance costs, as of September 30, 2021 was $1,265.7 million as compared to $198.0 million outstanding at December 31, 2020. The increase of $1,067.7 million in debt was primarily a result of the Company’s issuance of the 5.625% Notes. See Note 9 for information regarding the Company’s 5.625% Notes and $500.0 million revolving credit agreement.

The Company is currently in compliance with all of the terms and conditions of the Credit Agreement, and management believes, based on its current financial projections, that the Company will be in compliance with its covenants over the next twelve months.

If the Company loses all or a substantial portion of its lines of credit under its revolving credit agreement, or if the Company uses the maximum available amount under the agreement, it will be required to seek other sources of liquidity. If the Company were unable to find these sources of liquidity, for example through an equity offering or access to the capital markets, the Company’s ability to fund its working capital needs and any contingent obligations with respect to acquisitions and redeemable noncontrolling interests would be adversely affected.

Pursuant to the revolving credit agreement, the Company must comply with its total leverage ratio covenant, as such term is specifically defined in the agreement. For the period ended September 30, 2021, the Company’s calculation of each of these covenants, and the specific requirements under the revolving credit agreement, respectively, were calculated based on the trailing twelve months as follows:

59

	September 30, 2021
Total Leverage Ratio	3.08
Maximum per covenant	4.75

These ratios and measures are not based on GAAP and are not presented as alternative measures of operating performance or liquidity. Some of these ratios and measures include, among other things, pro forma adjustments for acquisitions, one-time charges, and other items, as defined in the Credit Agreement. They are presented here to demonstrate compliance with the covenants in the Credit Agreement, as non-compliance with such covenants could have a material adverse effect on the Company.

Contractual Obligations and Other Commercial Commitments

The Company’s agencies enter into contractual commitments with media providers and agreements with production companies on behalf of its clients at levels that exceed the revenue from services. Some of our agencies purchase media for clients and act as an agent for a disclosed principal. These commitments are included in Accounts payable and Accruals and other liabilities when the media services are delivered by the media providers. Stagwell takes precautions against default on payment for these services and has historically had a very low incidence of default. Stagwell is still exposed to the risk of significant uncollectible receivables from our clients. The risk of a material loss could significantly increase in periods of severe economic downturn.

Deferred acquisition consideration on the balance sheet consists of deferred obligations related to contingent and fixed purchase price payments. See Note 7 for additional information regarding contingent deferred acquisition consideration.

When acquiring less than 100% ownership of an entity, the Company may enter into agreements that give the Company an option to purchase, or require the Company to purchase, the incremental ownership interests under certain circumstances. Where the incremental purchase may be required of the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity. See Note 10 for additional information regarding noncontrolling interests and redeemable noncontrolling interests.

The Company intends to finance the cash portion of these contingent payment obligations using available cash from operations, borrowings under the revolving credit agreement (and refinancings thereof), and, if necessary, through the incurrence of additional debt and/or issuance of additional equity. The ultimate amount payable in the future relating to these transactions will vary because it is dependent on the future results of operations of the subject businesses and the timing of when these rights are exercised.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to market risk related to interest rates, foreign currencies and impairment risk.

Debt Instruments:  At September 30, 2021, the Company’s debt obligations consisted of amounts outstanding under its revolving credit agreement and the 5.625% Notes. The 5.625% Notes bear a fixed 5.625% interest rate. The revolving credit agreement bears interest at variable rates based upon the U.S. bank prime rate, U.S. base rate, LIBOR or its replacement SOFR, EURIBOR, and SONIA depending on the duration of the borrowing product. The Company’s ability to obtain the required bank syndication commitments depends in part on conditions in the bank market at the time of syndication. Given that there were $181.1 million in borrowings under the revolving credit agreement, as of September 30, 2021, a 1.0% increase or decrease in the weighted average interest rate, which was 2.45% at September 30, 2021, would have an interest impact of approximately $0.4 million.

Foreign Exchange:  While the Company primarily conducts business in markets that use the U.S. dollar, the Canadian dollar, the Euro and the British Pound, its non-U.S. operations transact business in numerous different currencies. The Company’s results of operations are subject to risk from the translation to the U.S. dollar of the revenue and expenses of its non-U.S. operations. The effects of currency exchange rate fluctuations on the translation of the Company’s results of operations are discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in Note 2. For the most part, revenues and expenses incurred related to the non-U.S. operations are denominated in their functional currency. This minimizes the impact that fluctuations in exchange rates will have on profit margins. Translation of intercompany debt, which is not intended to be repaid, is included in cumulative translation adjustments. Translation of current intercompany balances are included in net income (loss). The Company generally does not enter into foreign currency forward exchange contracts or other derivative financial instruments to hedge the effects of adverse fluctuations in foreign currency exchange rates.

Impairment Risk: At September 30, 2021, the Company did not have any impairment of goodwill. The Company reviews goodwill for impairment annually as of October 1st of each year or more frequently if indicators of potential impairment exist. See the Significant Accounting Policies in Note 2 for information related to impairment testing and the risk of potential impairment charges in future periods.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be included in our SEC reports is recorded, processed, summarized and reported within the applicable time periods specified by the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”), who is our principal executive officer, and Chief Financial Officer (“CFO”), who is our principal financial officer, as appropriate, to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can provide only reasonable assurance of achieving their control objectives. However, our disclosure controls and procedures are designed to provide reasonable assurances of achieving our control objectives.

We conducted an evaluation, under the supervision and with the participation of our management, including our CEO, CFO and management Disclosure Committee, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report pursuant to Rule 13a-15(e) and 15(d)-15(e) of the Exchange Act. Based on that evaluation, and in light of the material weaknesses identified in the internal controls over financial reporting of Stagwell Marketing Group LLC (“SMG”), our CEO and CFO concluded that, as of September 30, 2021, our disclosure controls and procedures are ineffective to ensure that decisions can be made timely with respect to required disclosures, as well as ensuring that the recording, processing, summarization and reporting of information required to be included in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2021 is appropriate.

Material Weaknesses in Internal Control Over Financial Reporting

In connection with the preparation of SMG's consolidated financial statements as of December 31, 2020, 2019 and 2018 and for the years then ended, SMG identified material weaknesses in its internal controls over financial reporting, including not designing or maintaining an effective control environment that meets SMG’s accounting and reporting requirements. Specifically, SMG did not maintain a sufficient complement of personnel with an appropriate degree of internal controls and accounting knowledge, experience and training commensurate with its accounting and reporting requirements. This material weakness contributed to the following additional material weaknesses:

•SMG did not establish effective controls in response to the risks of material misstatement, including designing and maintaining formal accounting policies, procedures and controls over journal entries, significant accounts and disclosures, in order to achieve complete and accurate financial accounting, reporting and disclosures;

•SMG did not design and maintain effective controls over information technology (“IT”) general controls for information systems that are relevant to the preparation of its financial statements. Specifically, SMG did not design and maintain: (i) program change management controls for the financial systems to ensure that information technology program and data changes affecting financial IT applications and underlying accounting records are identified, tested, authorized and implemented appropriately; (ii) appropriate user access controls to ensure appropriate segregation of duties and that adequately restrict user and privileged access to financial applications, programs and data to appropriate SMG personnel; (iii) computer operations controls to ensure critical data interfaces between systems are appropriately identified and monitored, and data backups are authorized and restorations monitored; and (iv) testing and approval controls for program development to ensure that new software development is aligned with business and IT requirements; and

•SMG has not established a sufficient risk assessment process to identify risks of material misstatement due to fraud and/or error and implement controls against such risks.

61

Remediation Efforts to Address Material Weakness

We are evaluating the weaknesses and intend to evaluate what remedial actions are necessary to enhance and improve our internal controls over financial reporting (“ICFR”) and therefore have not yet remediated the material weakness described above. Our remediation efforts will continue to be evaluated through 2022. We believe the controls that will be put in place will eliminate the material weaknesses and solidify the effectiveness of our internal control over financial reporting.

Changes in Internal Control Over Financial Reporting

The business combination of MDC with SMG, which was completed on August 2, 2021, had a material impact on the financial position, results of operations and cash flows of the combined company from the completion date through September 30, 2021. The business combination also resulted in material changes in the combined company’s internal controls over financial reporting. In addition to the remediation efforts described above, the Company is in the process of designing and integrating policies, processes, operations, technology and other components of internal controls over financial reporting of the combined company. Management will monitor the implementation of new controls and test the operating effectiveness when instances are available in future periods.

We have given consideration to the impact of COVID-19 and have concluded that there have been no changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.    Legal Proceedings

In the ordinary course of business, we are involved in various legal proceedings. We do not currently expect that these proceedings will have a material adverse effect on our results of operations, cash flows or financial position.

Item 1A.    Risk Factors

There have been no material changes that we are aware of from the risk factors set forth under “Risk Factors” in Exhibit 99.2 to our Current Report on Form 8-K filed with the Securities and Exchange Commission on August 10, 2021. These risks could materially and adversely affect our business, results of operations, financial condition, cash flows, projected results and future prospects. These risks are not exclusive and additional risks to which we are subject include the factors listed under “Note About Forward-Looking Statements” and the risks described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Quarterly Report on Form 10-Q.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds

In the three months ended September 30, 2021, the Company issued no Class A shares in transactions exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended.

Purchase of Equity Securities by the Issuer and Affiliated Purchasers

For the three months ended September 30, 2021, the Company made no open market purchases of its Class A, B, or C shares. Pursuant to its Combined Credit Agreement and the indenture governing the 5.625% Notes, the Company is currently limited as to the dollar amount of shares it may repurchase in the open market.

For the three months ended September 30, 2021, the Company’s employees surrendered Class A shares in connection with the required tax withholding resulting from the vesting of restricted stock. The Company paid these withholding taxes on behalf of the related employees. These Class A shares were subsequently retired and no longer remain outstanding as of September 30, 2021. The following table details those shares withheld during the third quarter of 2021:

FINANCIAL PERFORMANCE-BASED

RESTRICTED STOCK AGREEMENT (2021)

THIS AGREEMENT is made as of October 15, 2021 (the “Grant Date”), between Stagwell Inc., a Delaware corporation (the “Corporation”), and [        ] (the “Grantee”).

WHEREAS, the Corporation has adopted the 2016 Stock Incentive Plan (as amended, the “Plan”) for the purpose of providing employees of the Corporation and eligible non-employee directors of the Board of Directors a proprietary interest in pursuing the long-term growth, profitability and financial success of the Corporation (except as otherwise expressly set forth herein, capitalized terms used in this Agreement shall have the definitions set forth in the Plan);

WHEREAS, the Human Resources & Compensation Committee (the “Committee”) of the Board of Directors has determined that it is in the best interests of the Corporation to make the award set forth herein, which award will vest upon achievement by the Corporation of the specified financial growth target during the financial performance period of January 1, 2021 through December 31, 2023; and

WHEREAS, pursuant to the Plan, the Committee has determined to grant an Other Stock-Based Award to the Grantee in the form of shares of Class A common stock, subject to the terms, conditions and limitations provided herein, including achievement of the financial performance target, and in the Plan (the “Restricted Stock”).

NOW, THEREFORE, the parties hereto agree as follows:

    1.     Grant of Restricted Stock.

        1.1 The Corporation hereby grants to the Grantee, on the terms and conditions set forth in this Agreement, the number of shares of Restricted Stock set forth under the Grantee’s name on the signature page hereto (the “2021 Restricted Stock Award”).

        1.2 The Grantee’s rights with respect to all the shares of Restricted Stock underlying the 2021 Restricted Stock Award shall not vest and will remain forfeitable at all times prior to the Vesting Date, subject to the occurrence of a Permitted Acceleration Event (each as defined below). At any time, reference to the 2021 Restricted Stock Award shall be deemed to be a reference to the shares of Restricted Stock granted under Section 1.1 that have neither vested nor been forfeited pursuant to the terms of this Agreement.

        1.3 This Agreement shall be construed in accordance with, and subject to, the terms of the Plan (the provisions of which are incorporated herein by reference).

    2.     Rights of Grantee.

        Except as otherwise provided in this Agreement, the Grantee shall be entitled, at all times on and after the Grant Date, to exercise all rights of a shareholder with respect to the 2021 Restricted Stock Award, including the right to vote the shares of Restricted Stock. Prior to the Vesting Date, the Grantee shall not be entitled to transfer, sell, pledge, hypothecate or assign any portion of the 2021 Restricted Stock Award (collectively, the “Transfer Restrictions”), nor to receive current payment of dividends as per Section 5 below.

    3.     Vesting; Lapse of Restrictions.

        3.1 The 2021 Restricted Stock Award shall vest, and the Transfer Restrictions shall lapse, on March 31, 2024 (the “Vesting Date”), solely to the extent (A) the Corporation achieves the performance thresholds set forth below in Section 3.3, as determined by the Committee on or prior to March 31, 2024 (the date of such determination, the “Determination Date”), and (B) the Grantee continues to serve as an employee of the Corporation through the Vesting Date (the “Service Condition”); provided, however, that the 2021 Restricted Stock Award shall vest, and the Transfer Restrictions with respect to the 2021 Restricted Stock Award shall lapse, if sooner, as the result of any Permitted Acceleration Event, as provided below. “Permitted Acceleration Event” means one of the following: (i) termination of Grantee’s employment by the Corporation without Cause or by the Grantee for Good Reason (solely to the extent Grantee and the Corporation are parties to an employment agreement that defines Good Reason); (ii) Qualified Retirement; or (iii) the Grantee’s death or Disability.

In the event that Grantee’s employment is terminated (i) by the Corporation without Cause, or (ii) or by the Grantee for Good Reason, a number of shares of Restricted Stock under the 2021 Restricted Stock Award shall vest (A) if such termination occurs within one (1) year following the occurrence of a Change of a Control, on the termination date, in an amount equal to the full number of shares under the 2021 Restricted Stock Award, and (B) if such termination does not occur within one (1) year following the occurrence of a Change of a Control, on the Vesting Date, in an amount equal to the product of (x) the number of shares of Restricted Stock under the 2021 Restricted Stock Award that would otherwise performance vest in accordance with Section 3.3 hereof, if any, and (y) a fraction, the numerator of which shall be the number of full months of service completed by the Grantee from October 1, 2021 through the termination date, and the denominator of which shall be 30.

In the event of Grantee’s Qualified Retirement, the number of shares of Restricted Stock that performance vest in accordance with Section 3.3 hereof shall vest on the Vesting Date.

In the event of Grantee’s death or Disability, the full number of shares under the 2021 Restricted Stock Award shall vest on the date of death or Disability.

        3.2 Upon the earliest of (i) any termination of the Grantee for Cause; (ii) resignation by the Grantee without Good Reason or (iii) the failure by the Corporation to achieve the Minimum EBITDA Threshold, as determined by the Committee on the Determination Date, the 2021 Restricted Stock Award shall be forfeited and automatically transferred to and reacquired by the Corporation at no cost to the Corporation, and neither the Grantee nor any heirs, executors or successors of such Grantee shall thereafter have any right or interest in such shares of Restricted Stock.

        3.3    The 2021 Restricted Stock Award shall performance vest (but not satisfy the Service Condition) based upon the Corporation’s level of achievement of “EBITDA” (as defined below) during the performance period commencing on January 1, 2021 and ending on December 31, 2023 (the “Performance Period”), as described in this Section 3.3. All determinations required to be made hereunder shall be made by the Committee:

For the Performance Period, as determined on the Determination Date:

(i)If the Corporation achieves EBITDA for the Performance Period in an amount equal to or greater than the EBITDA Target, then 100% of the 2021 Restricted Stock Award shall performance vest on the Vesting Date;

2

(ii)If the Corporation achieves EBITDA for the Performance Period in an amount equal to or greater than 90% of the EBITDA Target (the “Minimum EBITDA Threshold”) but less than 100% of the EBITDA Target, then a prorated amount between 75% and 100% of the 2021 Restricted Stock Award shall performance vest on the Vesting Date, determined based on straight-line interpolation for EBITDA between the Minimum EBITDA Threshold and EBITDA Target; and

(iii)If the Corporation achieves EBITDA for the Performance Period in an amount less than the Minimum EBITDA Threshold, then no part of the Restricted Stock Award shall performance vest pursuant to this Section 3.3.

In the event of a Change of Control, 100% of the 2021 Restricted Stock Award shall performance vest (but not satisfy the Service Condition).

For purposes of the foregoing, the following terms shall have the meanings indicated below. Capitalized terms used in this Agreement but not defined herein shall have the meaning assigned to them in the Plan.

(a)“Cause” shall have the meaning set forth in the Grantee’s employment agreement with the Corporation. If such term is not defined in the Grantee’s employment agreement, then Cause means the Grantee’s termination by reason of (i) his/her continued or willful failure substantially to perform his/her duties for the Corporation, (ii) his/her willful and serious misconduct in connection with the performance of his/her duties for the Corporation, (iii) the Grantee’s conviction of, or entering a plea of guilty to, a crime that constitutes a felony or a crime involving moral turpitude, (iv) his/her fraudulent or dishonest conduct or (v) his/her material breach of any of his/her obligations or covenants under any written policies of the Corporation or any written agreement between such Grantee and the Corporation.

(b)“Change in Control” shall have the meaning set forth in Section 2(b) of the Plan.

(c)“Disability” shall have the meaning set forth in the Grantee’s employment agreement. If such term is not defined in the Grantee’s employment agreement, then Disability means the inability of the Grantee to have performed the Grantee’s material duties due to a physical or mental injury, infirmity or incapacity for one hundred eighty (180) consecutive days (including weekends and holidays) in any 365-day period, as determined by the Corporation in its reasonable discretion.

(d)“EBITDA” shall mean Adjusted EBITDA for the Performance Period as reported in the Corporation’s public filings, but excluding the effect of acquisitions made during the Performance Period; provided, however, that the Committee shall retain discretion to make appropriate adjustments to EBITDA for extraordinary events in accordance with the Plan.

(e)“EBITDA Target” shall equal $1.1 billion; provided, however, that the Committee shall retain discretion to make appropriate adjustments to the

3

EBITDA Target, including adjustments to take into account any asset disposition.

(f)“Employment Agreement” shall mean the Participant’s applicable employment agreement with the Corporation.

(g)“Good Reason” shall have the meaning set forth in the Grantee’s employment agreementwith the Corporation, and if not so defined shall be inapplicable.

(h)“Qualified Retirement” shall mean (i) the Participant’s voluntary termination of employment with the Corporation after (A) attaining seventy (70) years of age and (B) providing a minimum five (5) years of service to the Corporation or its affiliates or predecessors; provided that the Participant does not provide services to any competing business, other than as a member of a board of directors, from the date of retirement through the Vesting Date, or (ii) as determined by the Committee.

4.    Escrow and Delivery of Shares.

        4.1 Certificates (or an electronic “book entry” on the books of the Corporation's stock transfer agent) representing the shares of Restricted Stock shall be issued and held by the Corporation (or its stock transfer agent) in escrow (together with any stock transfer powers which the Corporation may request of Grantee) and shall remain in the custody of the Corporation (or its stock transfer agent) until (i) their delivery to the Grantee as set forth in Section 4.2 hereof, or (ii) their forfeiture and transfer to the Corporation as set forth in Section 3.2 hereof. The appointment of an independent escrow agent shall not be required.

        4.2    (a) Certificates (or an electronic “book entry”) representing those shares of Restricted Stock in respect of which the Transfer Restrictions have lapsed pursuant to Section 3.1 hereof shall be delivered to the Grantee as soon as practicable following the Vesting Date.

            (b) The Grantee, or the executors or administrators of the Grantee's estate, as the case may be, may receive, hold, sell or otherwise dispose of those shares of Restricted Stock delivered to him or her pursuant to this Section 4.2 free and clear of the Transfer Restrictions, but subject to compliance with all federal and state securities laws.

        4.3     (a) Each stock certificate issued pursuant to Section 4.1 shall bear a legend in substantially the following form:

THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS APPLICABLE TO RESTRICTED STOCK CONTAINED IN THE 2016 STOCK INCENTIVE PLAN (AS AMENDED, THE “PLAN”) AND A RESTRICTED STOCK AGREEMENT (THE “AGREEMENT”) BETWEEN THE CORPORATION AND THE REGISTERED OWNER OF THE SHARES REPRESENTED HEREBY. RELEASE FROM SUCH TERMS AND CONDITIONS SHALL BE MADE ONLY IN ACCORDANCE WITH THE PROVISIONS OF THE PLAN AND THE AGREEMENT, COPIES OF WHICH ARE ON FILE IN THE OFFICE OF THE SECRETARY OF THE CORPORATION.

4

            (b)     As soon as practicable following the Vesting Date, the Corporation shall issue a new certificate (or electronic “book entry”) for shares of the Restricted Stock which have become non-forfeitable in relation to such Vesting Date, which new certificate (or electronic “book entry”) shall not bear the legend set forth in paragraph (a) of this Section 4.3 and shall be delivered in accordance with Section 4.2 hereof.

    5. Dividends. All dividends declared and paid by the Corporation on shares underlying the 2021 Restricted Stock Award shall be deferred until the lapsing of the Transfer Restrictions pursuant to Section 3.1 and shall be distributed only to the extent the underlying shares of Restricted Stock vest in accordance with Section 3. The deferred dividends shall be held by the Corporation for the account of the Grantee until the Vesting Date, at which time the dividends shall be paid to the Grantee. Upon the forfeiture of the shares of Restricted Stock pursuant to Section 3, any deferred dividends shall also be forfeited to the Corporation.

    6. No Right to Continued Retention. Nothing in this Agreement or the Plan shall be interpreted or construed to confer upon the Grantee any right with respect to continuance as an employee, nor shall this Agreement or the Plan interfere in any way with the right of the Corporation to terminate the Grantee's service as an employee at any time.

7. Adjustments Upon Change in Capitalization. If, by operation of Section 10 of the Plan, the Grantee shall be entitled to new, additional or different shares of stock or securities of the Corporation or any successor corporation, such new, additional or different shares or other property shall thereupon be subject to all of the conditions and restrictions which were applicable to the shares of Restricted Stock immediately prior to the event and/or transaction.

    8.    Modification of Agreement. Except as set forth in the Plan and herein, this Agreement may be modified, amended, suspended or terminated, and any terms or conditions may be waived, but only by a written instrument executed by the parties hereto.

    9. Severability. Should any provision of this Agreement be held by a court of competent jurisdiction to be unenforceable or invalid for any reason, the remaining provisions of this Agreement shall not be affected by such holding and shall continue in full force and effect in accordance with their terms.

    10.    Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of New York without regard to its conflict of laws principle, except to the extent that the application of New York law would result in a violation of the Canadian Business Corporation Act.

    11.    Successors in Interest. This Agreement shall inure to the benefit of and be binding upon any successor to the Corporation. This Agreement shall inure to the benefit of the Grantee's heirs, executors, administrators and successors. All obligations imposed upon the Grantee and all rights granted to the Corporation under this Agreement shall be binding upon the Grantee's heirs, executors, administrators and successors.

12.    Tax Withholding. In addition to the rights of the Corporation pursuant to Section 14(a) of the Plan, upon the vesting of shares of Restricted Stock granted under this Agreement or otherwise, the Corporation may withhold (or sell on Grantee’s behalf) a number of shares of Class A common stock having a Fair Market Value on the vesting date sufficient to satisfy the federal, state and local

5

withholding tax requirements, if any, attributable to such vesting, but not greater than such withholding obligations.

Judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. Pending the resolution of any arbitration proceeding, Executive (and his beneficiaries) shall continue to receive all payments and benefits due under this Agreement or otherwise. No Party or arbitrator shall disclose in whole or in part to any other person, firm or entity any confidential information submitted in connection with the arbitration proceedings, except to the extent reasonably necessary to assist counsel in the arbitration, preparation for arbitration of the dispute, or in connection with a proceeding to confirm an arbitral award. Confidential Information may be disclosed to (i) attorneys, (ii) parties, and (iii) outside experts requested by either Party’s counsel to furnish technical or expert services or to give testimony at the arbitration proceedings, subject, in the case of such experts, to execution of a legally binding written statement that such expert is fully familiar with the terms of this provision, agree to comply with the confidentiality terms of this provision, and will not use any confidential information disclosed to such expert for personal or business advantage. The prevailing Party in any arbitration shall be entitled to receive its reasonable attorneys’ fees and costs from the other Party(ies) as may be awarded by the arbitrator.

(b)Notwithstanding anything above to the contrary, Executive shall be entitled, at his election, to enforce any indemnification or advancement rights in: (1) AAA arbitration; (2) the court in which the underlying dispute to which the claim for indemnification or advancement relates is being adjudicated; or (3) the federal and state courts located in the State of New York, which the Parties will contractually agree is an appropriate forum to adjudicate any such dispute.

(d)To the extent that any part of this Paragraph 18 is found to be legally unenforceable for any reason, that part shall be modified or deleted in such a manner as to render this Paragraph 18 (or the remainder of this Paragraph 18)

11

legally enforceable and as to ensure that except as otherwise provided in this Paragraph 18, all conflicts between the Company and Executive shall be resolved by neutral, binding arbitration. The remainder of this Paragraph 18 shall not be affected by any such modification or deletion but shall be construed as severable and independent. If a court finds that the arbitration procedures of this Paragraph 18 are not absolutely binding, then the Parties intend any arbitration decision to be fully admissible in evidence, given great weight by any finder of fact, and treated as determinative to the maximum extent permitted by law.

19.Withholdings. The Company may withhold from any amounts payable under this Agreement, including, without limitation, the Severance Payments, such federal, state or local taxes as shall be required to be withheld pursuant to any applicable law or regulation.

20.Golden Parachute Cutback.

(a)If the aggregate of all amounts and benefits due to Executive (or his beneficiaries), under this Agreement or any plan, program, agreement or arrangement of the Company (or any payments, benefits or entitlements by or on behalf of any person that effectuates a related transaction) (collectively, "Change in Control Benefits"), would cause Executive to have "parachute payments" as such term is defined in and under Section 280G of the Code, and would result in the imposition of excise taxes pursuant to Section 4999 of the Code, the Company will reduce (or cause to be reduced) any such payments and benefits so that the Parachute Value of all Change in Control Benefits, in the aggregate, equals the Safe Harbor Amount minus $1,000.00, but only if, by reason of such reduction, the Net After-Tax Benefit shall exceed the Net After-Tax Benefit if such reduction were not made (a "Required Reduction"). The determinations with respect to this Paragraph 20 shall be made by an independent auditor (the "Auditor"). The Auditor shall be Deloitte or another nationally-recognized United States public accounting firm chosen, and paid for, by the Company in consultation with Executive. Notwithstanding any provision to the contrary in this Agreement or in any other applicable plan, program, agreement or arrangement of the Company (A) the Auditor shall make its calculations using the methodology set forth in the spreadsheet prepared by Deloitte entitled MDC Partners Inc 280G v13 Detailed.pdf (the “Preliminary 280G Calculation”) (it being understood and agreed that the actual calculations set forth therein will be rerun as of the Termination Date to reflect changes in factual inputs); (B) unless required by a final decision of a court of competent jurisdiction or change in applicable law, each of the Parties agrees to treat, for all purposes, each portion of the Severance Payments as a “parachute payment” or not a “parachute payment” in a manner consistent with the Preliminary 280G Calculation and the Parties shall use their reasonable best efforts to support such treatment if challenged by any government tax authority, including the U.S. Internal Revenue Service, until a court of competent jurisdiction issues a final decision contradicting the Parties’ treatment of the Severance Payments; and (C) any Required Reduction shall be implemented as follows: first, by reducing any cash payments to be made to

12

Executive under Paragraph 3 above; second, by reducing the cash portions of any payments payable to Executive under any other agreements, policies, plans, programs or arrangements; and third, then by reducing non-cash portions of any payments or entitlement payable to Executive; provided that in all events any payment or entitlement which receives the favorable valuation under Q&A 24(b) and (c) of Treas. Reg. §1-280G shall not be reduced before all payments or entitlements which do not receive such favorable valuation have been reduced. In the case of the reductions to be made pursuant to each of the above-mentioned sequencing, the payment and/or benefit amounts to be reduced shall be reduced in the inverse order of their originally scheduled dates of payment or vesting, as applicable, and shall be so reduced (x) only to the extent that the payment and/or benefit otherwise to be paid, or the vesting of the award that otherwise would be accelerated, would be treated as a "parachute payment" within the meaning of Section 280G(b)(2)(A) of the Code, and (y) only to the extent necessary to achieve the Required Reduction.

(b)It is possible that after the determinations and selections made pursuant to Paragraph 20(a) Executive will receive Change in Control Benefits that are, in the aggregate, either more or less than the limitations provided in Paragraph 20(a) above (hereafter referred to as an "Excess Payment" or "Underpayment", respectively). In the event that it is determined (1) pursuant to a final and conclusive determination (x) by arbitration under Paragraph18 above, (y) by a court of competent jurisdiction, or (z) an Internal Revenue Service proceeding, or (2) by the Auditor upon request by Executive or the Company, that an Excess Payment has been made, then Executive shall refund the Excess Payment to the Company promptly on demand, together with an additional payment in an amount equal to the product obtained by multiplying the Excess Payment times the applicable annual federal rate (as determined in and under Section 1274(d) of the Code), or such higher rate as is necessary to ensure that the Change in Control Benefits are less than the Safe Harbor Amount, times a fraction whose numerator is the number of days elapsed from the date of Executive's receipt of such Excess Payment through the date of such refund and whose denominator is 365. In the event that it is determined (1) pursuant to a final and conclusive determination (x) by arbitration under Paragraph 18 above, (y) by a court of competent jurisdiction, or (z) an Internal Revenue Service proceeding, or (2) by the Auditor upon request by Executive or the Company, that an Underpayment has occurred, the Company shall pay an amount equal to the Underpayment to Executive within ten (10) days of such determination.

(c)All determinations made by the Auditor under this Paragraph 20 shall be final and binding upon the Company and Executive and shall be made as soon as reasonably practicable following the event giving rise to the Change in Control Benefits, or such later date on which a Change in Control Benefit has been paid.

(d)Definitions. The following terms shall have the following meanings for purposes of this Paragraph 20.

13

(A)"Net After-Tax Benefit" shall mean the present value (as determined in accordance with Section 280G(d)(4) of the Code) of the Change in Control Benefits net of all taxes imposed on Executive with respect thereto under Sections 1 and 4999 of the Code and under applicable state and local laws, determined by applying the highest marginal rate under Section 1 of the Code and under state and local laws which applied to Executive's taxable income for the immediately preceding taxable year, or such other rate(s) as Executive certifies is likely to apply to Executive in the relevant tax year(s).

(B)"Parachute Value" of a Change in Control Benefit shall mean the present value as of the date of the change of control for purposes of Section 280G of the Code of the portion of such Change in Control Benefit that constitutes a "parachute payment" under Section 280G(b)(2) of the Code and its implementing regulations, as determined by the Auditor for purposes of determining whether and to what extent the parachute tax will apply to such Change in Control Benefit.

(C)The "Safe Harbor Amount" means 2.99 times Executive's "base amount," within the meaning of Section 280G(b)(3) of the Code and its implementing regulations.

21.Severability. Whenever possible, each provision of this Agreement shall be interpreted in, such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or its validity and enforceability in any other jurisdiction, and, instead, this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, the remaining provisions of this Agreement shall continue in full force and effect without such provision.

22.Counterparts / Electronic Signatures. This Agreement may be executed in separate counterparts, each of which is deemed to be an original and all of which taken together constitute one and the same agreement. Facsimile and PDF signatures shall have the same force and effect as original signatures.

23.Assignment.

The rights and obligations of the Company hereunder shall be binding upon and run in favor of the successors and assigns of the Company.

24.Entire Agreement. The Company and Executive hereby acknowledge and represent that this Agreement contains the entire agreement between Executive and the Company concerning the Employee’s separation of employment from the Company, and upon its execution supersedes any and all previous agreements, including the Term Sheet between the Parties dated July 19, 2021 (the “Term Sheet”), concerning the subject matter hereof. The Parties further acknowledge and represent that the only earlier agreed-to promises, representations or warranties whatsoever made, express, implied or statutory, not contained herein, concerning the Employee’s separation of employment from the Company are set forth in the Term Sheet. The Employment Agreement, the Indemnification Agreement, the LTIP Restricted Stock Agreement and the LTIP Cash Award remain in force and effect, except as modified herein. In the event of any discrepancy or inconsistency between the terms of this Agreement and the terms of any prior agreement between or involving the Parties, including without limitation the Employment Agreement, the Indemnification Agreement, the LTIP Restricted Stock Agreement and the LTIP Cash Award, the terms of this Agreement shall control.

25.Headings. The headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Recent Developments

Business and Basis of Presentation

Stagwell Inc. (the “Company” or “Stagwell”), incorporated under the laws of Delaware, conducts its business through its networks and their Brands ("Brands"), which provide marketing and business solutions that realize the potential of combining data and creativity. Stagwell’s strategy is to build, grow and acquire market-leading businesses that deliver the modern suite of services that marketers need to thrive in a rapidly evolving business environment.

The accompanying consolidated financial statements include the accounts of Stagwell and its subsidiaries. Stagwell has prepared the unaudited condensed consolidated interim financial statements included herein in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting interim financial information on Form 10-Q. Accordingly, the financial statements have been condensed and do not include certain information and disclosures pursuant to these rules. The preparation of financial statements in conformity with GAAP requires us to make judgments, assumptions and estimates about current and future results of operations and cash flows that affect the amounts reported and disclosed. Actual results could differ from these estimates and assumptions. The consolidated results for interim periods are not necessarily indicative of results for the full year and should be read in conjunction with the Company’s other SEC filings.

On December 21, 2020, MDC Partners Inc. (“MDC”) and Stagwell Media LP (“Stagwell Media”) announced that they had entered into the Transaction Agreement, providing for the combination of MDC with the operating businesses and subsidiaries of Stagwell Media (the “Stagwell Subject Entities”). The Stagwell Subject Entities comprised Stagwell Marketing Group LLC (“Stagwell Marketing”) and its direct and indirect subsidiaries.

On August 2, 2021, we completed the previously announced combination of MDC Partners Inc. (“MDC”) and the operating businesses and subsidiaries of Stagwell Media LP. (“Stagwell Media”) and a series related transactions (such combination and transactions, the “Transactions”). The Transactions were treated as a reverse acquisition for financial reporting purposes, with MDC treated as the legal acquirer and Stagwell Marketing Group LLC (“Stagwell Marketing or SMG”) treated as the accounting acquirer. The results of MDC are included within the Unaudited Condensed Consolidated Statements of Operations for the period beginning on the date of the acquisition through the end of the respective period presented and the results of SMG are included for the entire period presented. See Note 4 for information in connection with the acquisition of MDC.

While a recovery from the COVID-19 pandemic is underway, economic conditions will be volatile as long as COVID-19 remains a public health threat. The Company continues to monitor developments. We will continue to monitor the worldwide public health threat, government actions to combat COVID-19 and the impact such developments may have on the overall economy, our clients and operations. The impact of the pandemic and the corresponding actions are reflected in our judgments, assumptions and estimates in the preparation of the financial statements. The judgments, assumptions and estimates will be updated and could result in different results in the future depending on the continued impact of the COVID-19 pandemic.

The accompanying financial statements reflect all adjustments, consisting of normally recurring accruals, which in the opinion of management are necessary for a fair presentation, in all material respects, of the information contained therein. Intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the prior year financial information to conform to the current year presentation.

Recent Developments

On September 23, 2021, the Company provided notices of conversion to each holder of record of each of the Company’s Series 6 and Series 8 Preferred Stock. See Note 12 for additional information in connection with the conversion of the Preferred Stock to Class A Common Stock.

On October 1, 2021 (the "closing date"), the Company entered into an agreement to purchase the remaining 26.7% interest in Targeted Victory it did not previously own for a combination of cash and Class A Common Stock, up to 50% with certain exceptions, determined at the option of the Company. The agreement provides for the purchase of half of the remaining interest on the closing date and the other half on July 31, 2023 ("second purchase"). The total purchase price, which is capped at $135,000 with certain exceptions, is based on a formula taking a multiple of the two-year average of earnings that includes the year of and the year subsequent to the year of the purchase. The seller has the option to extend the measurement period for two years in connection with the second purchase.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

The Company’s significant accounting policies are summarized as follows:

Principles of Consolidation.  The accompanying consolidated financial statements include the accounts of Stagwell Inc. and its domestic and international controlled subsidiaries that are not considered variable interest entities, and variable interest entities for which the Company is the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates.  The preparation of the consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities including goodwill, intangible assets, contingent deferred acquisition consideration, redeemable noncontrolling interests, deferred tax assets, right-of-use assets and the amounts of revenue and expenses reported during the period. These estimates are evaluated on an ongoing basis and are based on historical experience, current conditions and various other assumptions believed to be reasonable under the circumstances. These estimates require the use of assumptions about future performance, which are uncertain at the time of estimation. To the extent actual results differ from the assumptions used, results of operations and cash flows could be materially affected.

Fair Value.  The Company applies the fair value measurement guidance for financial assets and liabilities that are required to be measured at fair value and for non-financial assets and liabilities that are not required to be measured at fair value on a recurring basis, including goodwill, right-of-use assets and other identifiable intangible assets. See Note 13 included herein for additional information regarding fair value measurements.

Concentration of Credit Risk.  The Company provides marketing communications services to clients who operate in most industry sectors. Credit is granted to qualified clients in the ordinary course of business. Due to the diversified nature of the Company’s client base, the Company does not believe that it is exposed to a concentration of credit risk. No client accounted for more than 10% of the Company’s consolidated accounts receivable as of September 30, 2021 or December 31, 2020. No sales to an individual client accounted for more than 10% of revenue for the three and nine months ended September 30, 2021 and 2020.

Cash and Cash Equivalents.  The Company’s cash equivalents are primarily comprised of investments in overnight interest-bearing deposits, money market instruments and other short-term investments with original maturity dates of three months or less at the time of purchase. The Company has a concentration of credit risk in that there are cash deposits in excess of federally insured amounts and international cash balances may not qualify for foreign government insurance programs. To date, the Company has not experienced any losses on cash and cash equivalents.

Allowance for Doubtful Accounts.  Trade receivables are stated at invoiced amounts less allowances for doubtful accounts. The allowances represent estimated uncollectible receivables associated with potential customer defaults usually due to customers’ potential insolvency. The allowances include amounts for certain customers where a risk of default has been specifically identified. The assessment of the likelihood of customer defaults is based on various factors, including the length of time the receivables are past due, historical experience and existing economic conditions. Allowance for doubtful accounts was $5,294 and $5,109  at September 30, 2021 and December 31, 2020, respectively.

Expenditures Billable to Clients.  Expenditures billable to clients consist principally of outside vendor costs incurred on behalf of clients when providing services that have not yet been invoiced to clients. Such amounts are invoiced to clients at various times over the course of the period.

Fixed Assets.  Fixed assets are stated at cost, net of accumulated depreciation. Computers, furniture and fixtures, and capitalized software are depreciated on a straight-line basis over periods of three to ten years. Leasehold improvements are depreciated on a straight-line basis over the lesser of the term of the related lease or the estimated useful life of the asset. Repairs and maintenance costs are expensed as incurred. Accumulated depreciation was $39,357 and $28,365 at September 30, 2021 and December 31, 2020, respectively.

Leases. Effective January 1, 2019, the Company adopted Accounting Standards Codification, Leases (“ASC 842”). The Company recognizes on the balance sheet at the time of lease commencement a right-of-use lease asset and a lease liability, initially measured at the present value of the lease payments. All right-of-use lease assets are reviewed for impairment. With the adoption of ASC 842, the Company elected to apply the package of practical expedients: (i) whether a contract is or contains a lease, (ii) the classification of existing leases, and (iii) whether previously capitalized costs continue to qualify as initial indirect costs. Additionally, the Company elected the practical expedient to not separate non-lease components from lease components for all operating leases. See Note 8 included herein for further information on leases.

Impairment of Long-lived Assets.  A long-lived asset or asset group is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, the Company compares the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of such asset or asset group. If this comparison indicates that there is an impairment, the amount of the impairment is typically calculated using discounted expected future cash flows where observable fair values are not readily determinable. The discount rate applied to these cash flows is based on the Company’s weighted average cost of capital (“WACC”), risk adjusted where appropriate, or other appropriate discount rate.

Goodwill.  Goodwill (the excess of the acquisition cost over the fair value of the net assets acquired) acquired as a result of a business combination which is not subject to amortization is tested for impairment, at the reporting unit level, annually as of October 1st of each year, or more frequently if indicators of potential impairment exist.

For the annual impairment test, the Company has the option of assessing qualitative factors to determine whether it is more likely than not that the carrying amount of a reporting unit exceeds its fair value or performing a quantitative goodwill impairment test. Qualitative factors considered in the assessment include industry and market considerations, the competitive environment, overall financial performance, changing cost factors such as labor costs, and other factors specific to each reporting unit such as change in management or key personnel.

If the Company elects to perform the qualitative assessment and concludes that it is more likely than not that the fair value of the reporting unit is more than its carrying amount, then goodwill is not considered impaired and the quantitative impairment test is not necessary. For reporting units for which the qualitative assessment concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount and for reporting units for which the qualitative assessment is not performed, the Company will perform the quantitative impairment test, which compares the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit exceeds the carrying amount of the net assets assigned to that reporting unit, goodwill is not considered impaired. However, if the fair value of the reporting unit is lower than the carrying amount of the net assets assigned to the reporting unit, an impairment charge is recognized equal to the excess of the carrying amount over the fair value.

Determining the fair value of a reporting unit involves the use of significant estimates and assumptions. The Company uses a combination of the income approach, which incorporates the use of the discounted cash flow (“DCF”) method, and the market approach, which incorporates the use of earnings and revenue multiples based on market data. The Company generally applies an equal weighting to the income and market approaches for the impairment test. The income approach and the market approach both require the exercise of significant judgment, including judgment about the amount and timing of expected future cash flows, assumed terminal value and appropriate discount rates.

The DCF estimates incorporate expected cash flows that represent a spectrum of the amount and timing of possible cash flows of each reporting unit from a market participant perspective. The expected cash flows are developed from the Company’s long-range planning process using projections of operating results and related cash flows based on assumed long-term growth rates, demand trends and appropriate discount rates based on a reporting unit’s WACC as determined by considering the observable WACC of comparable companies and factors specific to the reporting unit. The terminal value is estimated using a constant growth method which requires an assumption about the expected long-term growth rate. The estimates are based on historical data and experience, industry projections, economic conditions, and the Company’s expectations.

Definite Lived Intangible Assets.  Definite lived intangible assets are subject to amortization over their useful lives. A straight-line amortization method is used over the estimated useful life which is representative of the pattern of how the economic benefits of the specific intangible asset is consumed. Intangible assets that are subject to amortization are reviewed for potential impairment at least annually or whenever events or circumstances indicate that carrying amounts may not be recoverable. The Company uses an income approach, which incorporates the use of the discounted cash flow (“DCF”) method.

Business Combinations. Business combinations are accounted for using the acquisition method and accordingly, the assets acquired (including identified intangible assets), the liabilities assumed and any noncontrolling interest in the acquired business are recorded at their acquisition date fair values.

For each acquisition, the Company undertakes a detailed review to identify other intangible assets and a valuation is performed for all such identified assets. The Company uses several market participant measurements to determine the estimated value. This approach includes consideration of similar and recent transactions, as well as utilizing discounted expected cash flow methodologies. A substantial portion of the intangible assets value that the Company acquires is the specialized know-how of the workforce, which is treated as part of goodwill and is not required to be valued separately. The majority of the value of the identifiable intangible assets acquired is derived from customer relationships, including the related customer contracts, as well as tradenames and trademarks.

Deferred Acquisition Consideration. Certain acquisitions include an initial payment at the time of closing and provide for future additional contingent purchase price payments. Contingent purchase price obligations for these transactions are recorded

as deferred acquisition consideration liabilities on the balance sheet, at the acquisition date fair value and are remeasured at each reporting period. These liabilities are derived from the projected performance of the acquired entity. These arrangements may be dependent on future events, such as the growth rate of the earnings of the relevant subsidiary during the contractual period. At each reporting date, the Company models each business’ future performance, including revenue growth and free cash flows, to estimate the value of each deferred acquisition consideration liability. The liability is adjusted quarterly based on changes in current information affecting each subsidiary’s current operating results and the impact this information will have on future results included in the calculation of the estimated liability. These adjustments are recorded in the results of operations. In instances where such contingent payments require the sellers’ continuous employment with the Company after the transaction, they are recorded as compensation expense in the Unaudited Condensed Consolidated Statements of Operations.

Redeemable Noncontrolling Interests. Many of the Company’s acquisitions include contractual arrangements where the noncontrolling shareholders have an option to purchase, or may require the Company to purchase, such noncontrolling shareholders’ incremental ownership interests under certain circumstances. The Company typically has similar call options under the same contractual terms. The amount of consideration under these contractual arrangements is not a fixed amount, but rather is dependent upon various valuation formulas, such as the average earnings of the relevant subsidiary through the date of exercise or the growth rate of the earnings of the relevant subsidiary during that period. In the event that an incremental purchase may be required by the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity on the Unaudited Condensed Consolidated Balance Sheets at their acquisition date fair value and adjusted for changes to their estimated redemption value through Retained earnings or Paid-in capital (when at an accumulated deficit) in the Unaudited Condensed Consolidated Balance Sheets (but not less than their initial redemption value), except for foreign currency translation adjustments. These adjustments will not impact the calculation of earnings (loss) per share if the redemption values are less than the estimated fair values.

Subsidiary and Equity Investment Stock Transactions. Transactions involving the purchase, sale or issuance of interests of a subsidiary where control is maintained are recorded as a reduction in the redeemable noncontrolling interests or noncontrolling interests, as applicable. Any difference between the purchase price and noncontrolling interest is recorded to Common stock and other paid-in capital in the Unaudited Condensed Consolidated Balance Sheets. In circumstances where the purchase of shares of an equity investment results in obtaining control, the existing carrying value of the investment is remeasured to the acquisition date fair value and any gain or loss is recognized in the results of operations.

Revenue Recognition.  The Company’s revenue is recognized when control of the promised services are transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. See Note 5 included herein for additional information.

Cost of Services.  Cost of services sold primarily consists of staff costs that are directly attributable to the Company’s client engagements, as well as third-party direct costs of production and delivery of services to its clients. Cost of services sold does not include depreciation, amortization, and other office and general expenses that are not directly attributable to the Company’s client engagements.

Deferred Financing Costs.  The Company uses the effective interest method to amortize deferred financing costs and any original issue premium or discount, if applicable. The Company also uses the straight-line method, which approximates the effective interest method, to amortize the deferred financing costs on the Credit Agreement.

Income Taxes. We account for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates and laws expected to be in effect when the differences are expected to reverse. The Company records associated interest and penalties as a component of income tax expense. The Company records a valuation allowance against deferred income tax assets when management believes it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Management evaluates on a quarterly basis all available positive and negative evidence considering factors such as the reversal of deferred income tax liabilities, taxable income in eligible carryback years, projected future taxable income, the character of the income tax asset, tax planning strategies, changes in tax laws and other factors. The periodic assessment of the net carrying value of the Company’s deferred tax assets under the applicable accounting rules requires significant management judgment. A change to any of these factors could impact the estimated valuation allowance and income tax expense.

Stock-Based Compensation.  Under the fair value method, compensation cost is measured at fair value at the date of grant and is expensed over the service period, generally the award’s vesting period. The Company uses its historical volatility derived over the expected term of the award to determine the volatility factor used in determining the fair value of the award. The Company recognizes forfeitures as they occur.

Stock-based awards that are settled in cash or equity at the option of the Company are recorded at fair value on the date of grant. The fair value measurement of the compensation cost for these awards is based on using the Black-Scholes option

pricing-model or other acceptable method and is recorded in Operating income over the service period, in this case the award’s vesting period.

The Company has adopted the straight-line attribution method for determining the compensation cost to be recorded during each accounting period. The Company commences recording compensation expense related to awards that are based on performance conditions under the straight-line attribution method when it is probable that such performance conditions will be met.

Income (Loss) per Common Share.  Basic income (loss) per common share is based upon the weighted average number of common shares outstanding during each period. Diluted income (loss) per common share is based on the above, in addition, if dilutive, common share equivalents, which include outstanding options, stock appreciation rights, and unvested restricted stock units. In periods of net loss, all potentially issuable common shares are excluded from diluted net loss per common share because they are anti-dilutive.

Foreign Currency Translation.  The functional and reporting currency of the Company is the US dollar. Generally, the Company’s subsidiaries use their local currency as their functional currency. Accordingly, the currency impacts of the translation of the Unaudited Condensed Consolidated Balance Sheets of the Company and its non-U.S. dollar based subsidiaries to U.S. dollar statements are included as cumulative translation adjustments in Accumulated other comprehensive income (loss). Translation of intercompany debt, which is not intended to be repaid, is included in cumulative translation adjustments. Cumulative translation adjustments are not included in net income (loss) unless they are actually realized through a sale or upon complete, or substantially complete, liquidation of the Company’s net investment in the foreign operation. Translation of current intercompany balances are included in net income (loss). The balance sheets of non-U.S. dollar based subsidiaries are translated at the period end rate. The Unaudited Condensed Consolidated Statements of Operations of the Company and its non-U.S. dollar based subsidiaries are translated at average exchange rates for the period.

Gains and losses arising from the Company’s foreign currency transactions are reflected in Foreign exchange, net on the Consolidated Statements of Operations.

New Accounting Pronouncements

New Accounting Pronouncements

In October 2021, the FASB issued ASU 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the recognition of an acquired contract liability and other items. ASU 2021-08 is effective January 1, 2023; however, the Company has early adopted the standard and retrospectively applied it to the financial statements herein.

In March 2020, the FASB issued ASU 2020-04, and in January subsequently issued ASU 2021-01, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, to provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 is effective upon issuance, through December 31, 2022. The Company is evaluating the impact of the adoption of this guidance on the Company's financial statements and disclosures.

Acquisitions and Dispositions

2021 Acquisition

On December 21, 2020, MDC Partners Inc. (“MDC”) and Stagwell Media LP (“Stagwell Media”) announced that they had entered into the Transaction Agreement, providing for the combination of MDC with the operating businesses and subsidiaries of Stagwell Media (the “Stagwell Subject Entities”). The Stagwell Subject Entities comprised Stagwell Marketing Group LLC (“Stagwell Marketing or SMG”) and its direct and indirect subsidiaries.

On August 2, 2021 (the “Closing Date”), we completed the combination of MDC and the Stagwell Subject Entities and a series of steps and related transactions (such combination and transactions, the “Transactions”). In connection with the Transactions, among other things, (i) MDC completed a series of transactions pursuant to which it emerged as a wholly owned subsidiary of the Company, converted into a Delaware limited liability company and changed its name to Midas OpCo Holdings LLC (“OpCo”); (ii) Stagwell Media contributed the equity interests of Stagwell Marketing and its direct and indirect subsidiaries to OpCo; and (iii) the Company converted into a Delaware corporation, succeeded MDC as the publicly-traded company and changed its name to Stagwell Inc.

In respect of the Transactions, the acquired assets and assumed liabilities, together with acquired processes and employees, represent a business as defined in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”). The Transactions was accounted for as a reverse acquisition using the acquisition method of accounting, pursuant to FASB Topic 805-10, Business Combinations, with MDC treated as the legal

acquirer and SMG treated as the accounting acquirer. In identifying SMG as the acquiring entity for accounting purposes, MDC and SMG took into account a number of factors, including the relative voting rights and the corporate governance structure of the Company. SMG is considered the accounting acquirer since Stagwell Media controls the board of directors of the Company following the Transactions and received an indirect ownership interest in the Company’s only operating subsidiary, OpCo, of 69.55% ownership of OpCo’s common units. However, no single factor was the sole determinant in the overall conclusion that Stagwell is the acquirer for accounting purposes; rather all factors were considered in arriving at such conclusion. Under the acquisition method of accounting, the assets and liabilities of MDC, as the accounting acquiree, were recorded at their respective fair value as of the date the Transactions were completed.

On August 2, 2021, an aggregate of 179,970,051 shares of the Company’s Class C common stock were issued to Stagwell Media in exchange for $1,800 (the “Stagwell New MDC Contribution”). The Class C common stock does not participate in the earnings of the Company. Additionally, an aggregate of 179,970,051 OpCo common units were issued to Stagwell Media in exchange for the equity interests of the Stagwell Subject Entities (the “Stagwell OpCo Contribution”).

The fair value of the purchase consideration is $426,396, consisting of approximately 80,000,000 shares of the Company’s Class A and B common stock and common stock equivalents based on a per share price of approximately $5.42, the closing stock price on the date of the combination.

ASC 805 requires the allocation of the purchase price consideration to the fair value of the identified assets acquired and liabilities assumed upon consummation of a business combination. For this purpose, fair value shall be determined in accordance with the fair value concepts defined in ASC 820, “Fair Value Measurements and Disclosures,” (“ASC 820”). Fair value is defined in ASC 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements can be highly subjective and can involve a high degree of estimation.

The total purchase price to acquire MDC has been allocated to the assets acquired and assumed liabilities based upon preliminary estimated fair values, with any excess purchase price allocated to goodwill. The fair value of the acquired assets and assumed liabilities as of the date of acquisition are based on preliminary estimates assisted, in part, by a third-party valuation expert. The estimates are subject to change upon the finalization of appraisals and other valuation analyses, which are expected to be completed no later than one year from the date of acquisition. Although the completion of the valuation activities may result in asset and liability fair values that are different from the preliminary estimates included herein, it is not expected that those differences would alter the understanding of the impact of this transaction on the consolidated financial position and results of operations of the Company.

The preliminary purchase price allocation is as follows:

	Amount
Cash and cash equivalents	$	130,155
Accounts receivable	419,742
Other current assets	44,508
Fixed Assets	80,047
Right-of-use lease assets - operating leases	293,034
Intangible assets	809,900
Other assets	16,928
Accounts payable	(165,443)
Accruals and other liabilities	(308,757)
Advance billings	(211,687)
Current portion of lease liabilities	(55,878)
Current portion of deferred acquisition consideration	(53,054)
Long-term debt	(1,011,690)
Long-term portion of deferred acquisition consideration	(8,056)
Long-term portion of lease liabilities	(292,497)
Other liabilities	(131,897)
Redeemable noncontrolling interests	(30,830)
Preferred shares	(209,980)
Noncontrolling interests	(158,230)
Net liabilities assumed	(843,685)
Goodwill	1,270,081
Purchase price consideration	$	426,396

The excess of purchase consideration over the fair value of the net assets acquired was recorded as goodwill, which is primarily attributed to the assembled workforce of MDC. Goodwill of $1,041,277, $166,658 and $62,146 was assigned to the Integrated Agencies Network, the Media Network and the Communications Network reportable segments, respectively. The majority of the goodwill is non-deductible for income tax purposes.

Intangible assets consist of trade names and customer relationships. We amortize purchased intangible assets on a straight-line basis over their respective useful lives. The weighted average life of the total acquired identifiable intangible assets is 13 years. The following table presents the details of identifiable intangible assets acquired.

	Estimated Fair Value		Estimated Useful Life in Years
Trade Names	$	98,000	10
Customer Relationships	711,900		6-15
Total Acquired Intangible Assets	$	809,900

MDC operating results are included in the Condensed Consolidated Statements of Operations from the date of the acquisition through September 30, 2021 with revenue of $241,257 and a nominal net loss.

Transaction expenses were approximately $15,000 for the nine months ended September 30, 2021.

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

The Company’s revenue recognition policies are established in accordance with ASC 606, and accordingly, revenue is recognized when control of the promised goods or services is transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

The Stagwell network provides an extensive range of services to our clients, offering a variety of marketing and communication capabilities including strategy, creative and production for advertising campaigns across a variety of platforms (print, digital, social media, television broadcast), public relations services including strategy, editorial, crisis support or issues management, media training, influencer engagement and events management. We also provide media buying and planning across a range of platforms (out-of-home, paid search, social media, lead generation, programmatic, television broadcast), experiential marketing and application/website design and development.

The primary source of the Company’s revenue is from agency arrangements in the form of fees for services performed, commissions, and from performance incentives or bonuses, depending on the terms of the client contract. In all circumstances, revenue is only recognized when collection is reasonably assured. Certain of the Company’s contractual arrangements have more than one performance obligation. For such arrangements, revenue is allocated to each performance obligation based on its relative stand-alone selling price. Stand-alone selling prices are determined based on the prices charged to clients or using expected cost plus margin.

The determination of our performance obligations is specific to the services included within each contract. Based on a client’s requirements within the contract, and how these services are provided, multiple services could represent separate performance obligations or be combined and considered one performance obligation. Contracts that contain services that are not significantly integrated or interdependent, and that do not significantly modify or customize each other, are considered separate performance obligations. Typically, we consider media planning, media buying, creative (or strategy), production and experiential marketing services to be separate performance obligations if included in the same contract as each of these services can be provided on a stand-alone basis, and do not significantly modify or customize each other. Public relations services and application/website design and development are typically each considered one performance obligation as there is a significant integration of these services into a combined output.

Certain of the Company’s contracts consist of a single performance obligation. In these instances, the Company does not consider the underlying activities as separate or distinct performance obligations because its services are highly interrelated, and the integration of the various components is essential to the overall promise to the Company’s customer. In certain of the Company’s client contracts, the performance obligation is a stand-ready obligation because the Company provides a constant level of similar services over the term of the contract.

We typically satisfy our performance obligations over time, as services are performed. Fees for services are typically recognized using input methods (direct labor hours, materials and third-party costs) that correspond with efforts incurred to date in relation to total estimated efforts to complete the contract. To a lesser extent, revenue is recognized using output measures, such as impressions or ongoing reporting. For client contracts when the Company has a stand-ready obligation to perform services on an ongoing basis over the life of the contract, where the scope of these arrangements includes an undefined number of broad activities and there are no significant gaps in performing the services, the Company recognizes revenue ratably using a time-based measure. In addition, for client contracts where the Company is providing online subscription-based hosted services, it recognizes revenue ratably over the contract term. Point in time recognition primarily relates to certain commission-based contracts, which are recognized upon the placement of advertisements in various media when the Company has no further performance obligation.

Revenue is recognized net of sales and other taxes due to be collected and remitted to governmental authorities. The Company’s contracts typically provide for termination by either party within 30 to 90 days. Although payment terms vary by client, they are typically within 30 to 60 days. In addition, the Company generally has the right to payment for all services provided through the end of the contract or termination date.

Within each contract, we identify whether the Company is principal or agent at the performance obligation level. In arrangements where the Company has substantive control over the service before transferring it to the client, and is primarily responsible for integrating the services into the final deliverables, we act as principal. In these arrangements, revenue is recorded at the gross amount billed. Accordingly, for these contracts the Company has included reimbursed expenses in revenue. In other arrangements where a third-party supplier, rather than the Company, is primarily responsible for the integration of services into the final deliverables, and thus the Company is solely arranging for the third-party supplier to provide these services to our client, we generally act as agent and record revenue equal to the net amount retained, when the fee or commission is earned. The role of Stagwell’s agencies under a production services agreement is to facilitate a client’s purchasing of production capabilities from a third-party production company in accordance with the client’s strategy and guidelines. The obligation of Stagwell’s agencies under media buying services is to negotiate and purchase advertising media from a third-party media vendor on behalf of a client to execute its media plan. We do not obtain control prior to transferring these services to our clients; therefore, we primarily act as agent for production and media buying services.                                    

A small portion of the Company’s contractual arrangements with clients include performance incentive provisions, which allow the Company to earn additional revenues as a result of its performance relative to both quantitative and qualitative goals. Incentive compensation is primarily estimated using the most likely amount method and is included in revenue up to the amount that is not expected to result in a reversal of a significant amount of cumulative revenue recognized. We recognize revenue related to performance incentives as we satisfy the performance obligation to which the performance incentives are related.

Disaggregated Revenue Data

The Company provides a broad range of services to a large base of clients across the full spectrum of verticals globally. The primary source of revenue is from agency arrangements in the form of fees for services performed, commissions, and from

performance incentives or bonuses. Certain clients may engage with the Company in various geographic locations, across multiple disciplines, and through multiple Brands. Representation of a client rarely means that Stagwell handles marketing communications for all brands or product lines of the client in every geographical location. The Company’s Brands often cooperate with one another through referrals and the sharing of both services and expertise, which enables Stagwell to service clients’ varied marketing needs by crafting custom integrated solutions. Additionally, the Company maintains separate, independent operating companies to enable it to effectively manage potential conflicts of interest by representing competing clients across the Stagwell network.

The following table presents revenue disaggregated by lines of business for the three and nine months ended September 30, 2021 and 2020:

		Three Months Ended September 30,				Nine Months Ended September 30,

Stagwell has historically largely focused where the Company was founded in North America, the largest market for its services in the world. The Company has expanded its global footprint to support clients looking for help to grow their businesses in new markets. Stagwell’s Brands are located in the United States and United Kingdom, and an additional eighteen countries around the world. In the past, some clients have responded to weakening economic conditions with reductions to their marketing budgets, which included discretionary components that are easier to reduce in the short term than other operating expenses.

The following table presents revenue disaggregated by geography for the three and nine months ended September 30, 2021 and 2020:

Contract Assets and Liabilities

Contract assets consist of fees and reimbursable outside vendor costs incurred on behalf of clients when providing advertising, marketing and corporate communications services that have not yet been invoiced to clients. Unbilled service fees were $137,938 and $30,570 at September 30, 2021 and December 31, 2020, respectively, and are included as a component of Accounts receivable on the Unaudited Condensed Consolidated Balance Sheets. Outside vendor costs incurred on behalf of clients which have yet to be invoiced were $37,101 and $11,063 at September 30, 2021 and December 31, 2020, respectively, and are included on the Unaudited Condensed Consolidated Balance Sheets as Expenditures billable to clients. Such amounts are invoiced to clients at various times over the course of providing services. Additions to contract assets of $99,853 were added during the period as a result of the acquisition of MDC.

Contract liabilities consist of fees billed to clients in excess of fees recognized as revenue and are classified as Advance billings and also are included within Accruals and other liabilities on the Company’s Unaudited Condensed Consolidated Balance Sheets. In arrangements in which we are acting as an agent, the revenue recognition related to the contract liability is presented on a net basis within the Unaudited Condensed Consolidated Statements of Operations. Advance billings at September 30, 2021 and December 31, 2020 were $286,790 and $66,418, respectively. The increase in the Advance billings balance of $220,372 for the nine months ended September 30, 2021 was primarily driven by the acquisition of MDC, representing a $211,687 increase, and by cash payments received or due in advance of satisfying our performance obligations, offset by $45,432 of revenues recognized that were included in the Advance billings balances as of December 31, 2020 and reductions due to the incurrence of third-party costs. Contract liabilities classified within Accruals and other liabilities at September 30, 2021 and December 31, 2020 were $168,882 and $9,311, respectively. The increase in the balance of $159,571 for the nine months ended September 30, 2021 was primarily driven by was primarily driven by the acquisition of MDC, representing a $108,488 increase, and by cash payments received or due in advance of satisfying our performance obligations, offset by $9,311 of revenues recognized that were included in the balance as of December 31, 2020 and reductions due to the incurrence of third-party costs.

Changes in the contract asset and liability balances during the nine months ended September 30, 2021 were not materially impacted by write offs, impairment losses or any other factors.

The majority of our contracts are for periods of one year or less. For those contracts with a term of more than one year, we had approximately $8,498 of unsatisfied performance obligations as of September 30, 2021, of which we expect to recognize approximately 35% in 2021, 60% in 2022

There were 123,849,000 Preferred Shares outstanding which were convertible into 33,035,446 of Class A common shares at September 30, 2021. These Preferred Shares were anti-dilutive for each period presented in the table above and are therefore excluded from the diluted earnings per share calculation.

The combination of MDC and SMG was completed on August 2, 2021, which was treated as a reverse acquisition for financial reporting purposes. SMG was treated as the accounting acquirer and MDC was the accounting acquiree. Therefore, under applicable accounting principles, the historical financial results of SMG prior to August 2, 2021 are considered our historical financial results. Accordingly, historical information presented in this Form 10-Q for events occurring or periods ending before August 2, 2021 does not reflect the impact of the Transactions or the financial results of MDC and may not be comparable with historical information for events occurring or periods ending on or after August 2, 2021.

SMG’s equity structure, prior to the combination with MDC, was a non-unitized single member limited liability company, resulting in all components of equity attributable to the member being reported within Members' Capital. Given that SMG was a non-unitized single member limited liability company, net income (loss) prior to the combination is not applicable for purposes of calculating earnings per share. Therefore, the net income (loss) in the table above includes the income or loss for the period beginning on the acquisition date through the end of the respective reporting period and as such will not reconcile to the respective amounts presented within the Unaudited Condensed Consolidated Statements of Operations.

Deferred Acquisition Consideration

Acquisitions and Dispositions

2021 Acquisition

On December 21, 2020, MDC Partners Inc. (“MDC”) and Stagwell Media LP (“Stagwell Media”) announced that they had entered into the Transaction Agreement, providing for the combination of MDC with the operating businesses and subsidiaries of Stagwell Media (the “Stagwell Subject Entities”). The Stagwell Subject Entities comprised Stagwell Marketing Group LLC (“Stagwell Marketing or SMG”) and its direct and indirect subsidiaries.

On August 2, 2021 (the “Closing Date”), we completed the combination of MDC and the Stagwell Subject Entities and a series of steps and related transactions (such combination and transactions, the “Transactions”). In connection with the Transactions, among other things, (i) MDC completed a series of transactions pursuant to which it emerged as a wholly owned subsidiary of the Company, converted into a Delaware limited liability company and changed its name to Midas OpCo Holdings LLC (“OpCo”); (ii) Stagwell Media contributed the equity interests of Stagwell Marketing and its direct and indirect subsidiaries to OpCo; and (iii) the Company converted into a Delaware corporation, succeeded MDC as the publicly-traded company and changed its name to Stagwell Inc.

In respect of the Transactions, the acquired assets and assumed liabilities, together with acquired processes and employees, represent a business as defined in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”). The Transactions was accounted for as a reverse acquisition using the acquisition method of accounting, pursuant to FASB Topic 805-10, Business Combinations, with MDC treated as the legal

acquirer and SMG treated as the accounting acquirer. In identifying SMG as the acquiring entity for accounting purposes, MDC and SMG took into account a number of factors, including the relative voting rights and the corporate governance structure of the Company. SMG is considered the accounting acquirer since Stagwell Media controls the board of directors of the Company following the Transactions and received an indirect ownership interest in the Company’s only operating subsidiary, OpCo, of 69.55% ownership of OpCo’s common units. However, no single factor was the sole determinant in the overall conclusion that Stagwell is the acquirer for accounting purposes; rather all factors were considered in arriving at such conclusion. Under the acquisition method of accounting, the assets and liabilities of MDC, as the accounting acquiree, were recorded at their respective fair value as of the date the Transactions were completed.

On August 2, 2021, an aggregate of 179,970,051 shares of the Company’s Class C common stock were issued to Stagwell Media in exchange for $1,800 (the “Stagwell New MDC Contribution”). The Class C common stock does not participate in the earnings of the Company. Additionally, an aggregate of 179,970,051 OpCo common units were issued to Stagwell Media in exchange for the equity interests of the Stagwell Subject Entities (the “Stagwell OpCo Contribution”).

The fair value of the purchase consideration is $426,396, consisting of approximately 80,000,000 shares of the Company’s Class A and B common stock and common stock equivalents based on a per share price of approximately $5.42, the closing stock price on the date of the combination.

ASC 805 requires the allocation of the purchase price consideration to the fair value of the identified assets acquired and liabilities assumed upon consummation of a business combination. For this purpose, fair value shall be determined in accordance with the fair value concepts defined in ASC 820, “Fair Value Measurements and Disclosures,” (“ASC 820”). Fair value is defined in ASC 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements can be highly subjective and can involve a high degree of estimation.

The total purchase price to acquire MDC has been allocated to the assets acquired and assumed liabilities based upon preliminary estimated fair values, with any excess purchase price allocated to goodwill. The fair value of the acquired assets and assumed liabilities as of the date of acquisition are based on preliminary estimates assisted, in part, by a third-party valuation expert. The estimates are subject to change upon the finalization of appraisals and other valuation analyses, which are expected to be completed no later than one year from the date of acquisition. Although the completion of the valuation activities may result in asset and liability fair values that are different from the preliminary estimates included herein, it is not expected that those differences would alter the understanding of the impact of this transaction on the consolidated financial position and results of operations of the Company.

The preliminary purchase price allocation is as follows:

	Amount
Cash and cash equivalents	$	130,155
Accounts receivable	419,742
Other current assets	44,508
Fixed Assets	80,047
Right-of-use lease assets - operating leases	293,034
Intangible assets	809,900
Other assets	16,928
Accounts payable	(165,443)
Accruals and other liabilities	(308,757)

Current portion of lease liabilities	(55,878)
Current portion of deferred acquisition consideration	(53,054)
Long-term debt	(1,011,690)
Long-term portion of deferred acquisition consideration	(8,056)
Long-term portion of lease liabilities	(292,497)
Other liabilities	(131,897)
Redeemable noncontrolling interests	(30,830)
Preferred shares	(209,980)
Noncontrolling interests	(158,230)
Net liabilities assumed	(843,685)
Goodwill	1,270,081
Purchase price consideration	$	426,396

The excess of purchase consideration over the fair value of the net assets acquired was recorded as goodwill, which is primarily attributed to the assembled workforce of MDC. Goodwill of $1,041,277, $166,658 and $62,146 was assigned to the Integrated Agencies Network, the Media Network and the Communications Network reportable segments, respectively. The majority of the goodwill is non-deductible for income tax purposes.

Intangible assets consist of trade names and customer relationships. We amortize purchased intangible assets on a straight-line basis over their respective useful lives. The weighted average life of the total acquired identifiable intangible assets is 13 years. The following table presents the details of identifiable intangible assets acquired.

	Estimated Fair Value		Estimated Useful Life in Years
Trade Names	$	98,000	10
Customer Relationships	711,900		6-15

Leases [Abstract]

Leases

Leases

The Company leases office space in North America, Europe, Asia, South America, and Australia. This space is primarily used for office and administrative purposes by the Company’s employees in performing professional services. These leases are classified as operating leases and expire between years 2021 through 2034. The Company’s finance leases are immaterial.

The Company’s leasing policies are established in accordance with ASC 842, and accordingly, the Company recognizes on the balance sheet at the time of lease commencement a right-of-use lease asset and a lease liability, initially measured at the present value of the lease payments. Right-of-use lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. All right-of-use lease assets are reviewed for impairment. As the Company’s implicit rate in its leases is not readily determinable, in

determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the commencement date. Lease payments included in the measurement of the lease liability are comprised of noncancelable lease payments, payments based upon an index or rate, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated early.

Lease costs are recognized in the Unaudited Condensed Consolidated Statements of Operations over the lease term on a straight-line basis. Leasehold improvements are depreciated on a straight-line basis over the lesser of the term of the related lease or the estimated useful life of the asset. 

Some of the Company’s leases contain variable lease payments, including payments based upon an index or rate. Variable lease payments based upon an index or rate are initially measured using the index or rate in effect at the lease commencement date and are included within the lease liabilities. Lease liabilities are not remeasured as a result of changes in the index or rate, rather changes in these types of payments are recognized in the period in which the obligation for those payments is incurred. In addition, some of our leases contain variable payments for utilities, insurance, real estate tax, repairs and maintenance, and other variable operating expenses. Such amounts are not included in the measurement of the lease liability and are recognized in the period when the facts and circumstances which the variable lease payments are based upon occur.

Some of the Company’s leases include options to extend or renew the leases through 2044. The renewal and extension options are not included in the lease term as the Company is not reasonably certain that it will exercise its option.

From time to time, the Company enters into sublease arrangements both with unrelated third-parties and with our partner agencies. These leases are classified as operating leases and expire between years 2021 through 2031. Sublease income is recognized over the lease term on a straight-line basis. Currently, the Company subleases office space in North America, Asia, Europe and Australia.

As of September 30, 2021, the Company has entered into three operating leases for which the commencement date has not yet occurred as the premises are in the process of being prepared for occupancy by the landlord. Accordingly, these three leases represent an obligation of the Company that is not reflected within the Unaudited Condensed Consolidated Balance Sheets as of September 30, 2021. The aggregate future liability related to these leases is approximately $31,310.

The discount rate used for leases accounted for under ASC 842 is the Company’s collateralized credit adjusted borrowing rate.

The following table presents lease costs and other quantitative information for the three and nine months ended September 30, 2021 and 2020:

	Three Months Ended September 30,						Nine Months Ended September 30,

The amortization of debt issuance costs included in Interest expense, net on the Unaudited Condensed Consolidated Statements of Operations for the nine months ended September 30, 2021 and 2020 was $2,092 and $396, respectively.

Revolving Credit Agreement

On November 18, 2019, the Company entered into a debt agreement (“JPM Syndicated Facility”) with a syndicate of banks led by JPMorgan Chase Bank, N.A (“JPM”). The JPM Syndicated Facility consisted of a five-year revolving credit facility of $265,000 (“JPM Revolver”) with the right to be increased by an additional $150,000. On March 18, 2020, the Company increased the commitments on the JPM Revolver by $60,000 to $325,000.

On August 2, 2021, in connection with the closing of the acquisition of MDC, the Company entered into an amended and restated credit agreement (the “Combined Credit Agreement”) with a syndicate of banks led by JPM to increase commitments on the existing JPM Revolver. The Combined Credit Agreement consists of a $500,000 senior secured revolving credit facility with a five-year maturity.

The Combined Credit Agreement contains sub-limits for revolving loans and letters of credit of $50,000 for loans denominated in pounds sterling or euros. It also includes an accordion feature under which the Company may request, subject to lender approval and certain conditions, to increase the amount of the commitments to an aggregate amount not to exceed $650,000.

Borrowings under the Combined Credit Agreement bear interest at a rate equal to, at the Company’s option, (i) the greatest of (a) the prime rate of interest announced from time to time by JPM, (b) the federal funds effective rate from time to time plus 0.50% and (c) the LIBOR rate plus 1%, in each case, plus the applicable margin (calculated based on the Company’s total leverage ratio) at that time or (ii) the LIBOR rate plus the applicable margin (calculated based on the Company’s total leverage ratio) at that time. The Company is also required to pay an unused revolver fee to the lenders under the Combined Credit Agreement in respect of the unused commitments thereunder ranging from 0.15% to 0.30% of unused commitments depending on the total leverage ratio, as well as customary letter of credit fees.

Advances under the Combined Credit Agreement may be prepaid in whole or in part from time to time without penalty or premium. The Combined Credit Agreement commitment may be reduced by the Company from time to time. Principal amounts outstanding under the Combined Credit Agreement are due and payable in full at maturity within five years of the date of the Combined Credit Agreement.

If an event of default occurs under the Combined Credit Agreement or any future secured indebtedness, the holders of such secured indebtedness will have a prior right to our assets securing such indebtedness, to the exclusion of the holders of the 5.625% Notes (as defined below), even if we are in default with respect to the 5.625% Notes. In that event, our assets securing such indebtedness would first be used to repay in full all indebtedness and other obligations secured by them (including all amounts outstanding under the Combined Credit Agreement), resulting in all or a portion of our assets being unavailable to satisfy the claims of the holders of the 5.625% Notes and other unsecured indebtedness.

The Combined Credit Agreement contains a number of financial and nonfinancial covenants and is guaranteed by substantially all of our present and future subsidiaries, subject to customary exceptions.

The Company was in compliance with all covenants at September 30, 2021.

A portion of the Combined Credit Agreement in an amount not to exceed $50,000 is available for the issuance of standby letters of credit. At September 30, 2021 and December 31, 2020, the Company had issued undrawn outstanding letters of credit of $25,628 and $5,500, respectively.

Term Loan

On November 13, 2020, the Company, JPM as administrative agent, and a group of lenders entered into a term loan agreement that provided the Company with a delayed draw term loan in an aggregate principal amount of $90,000 (“DD Term Loan A”) with a maturity date of November 13, 2023.

In connection with the acquisition of MDC, the Company drew down on the full amount of the DD Term Loan A, repaid the amount with the Combined Credit Agreement, and terminated the agreement.

Line of Credit

On August 2, 2021, the Company entered into an unsecured uncommitted line of credit in the aggregate amount of $30,000 with JPM (the “Line of Credit”) to meet certain short-term working capital needs. The Line of Credit expired on August 20, 2021.

Senior Notes

In August 2021, the Company issued $1,100,000 aggregate principal amount of 5.625% senior notes ("5.625% Notes"). A portion of the proceeds from the issuance of the 5.625% Notes was used to redeem $870,300 aggregate principal amount of the outstanding 7.50% Senior Notes due 2024 (the “Existing Notes”) for a price of $904,200. This price is equal to 101.625% of the outstanding principal amount of the Existing Notes being redeemed, plus, accrued, and unpaid interest on the principal amount of such Existing Notes. The Company did not recognize a gain or loss on redemption.

The 5.625% Notes are due August 15, 2029 and bear interest of 5.625% to be paid on February 15 and August 15 of each year, commencing on February 15, 2022.

The 5.625% Notes are guaranteed on a senior unsecured basis by substantially all of the Company’s subsidiaries. The 5.625% Notes rank (i) equally in right of payment with all of the Company’s or any guarantor’s existing and future unsubordinated indebtedness, (ii) senior in right of payment to the Company’s or any guarantor’s existing and future subordinated indebtedness, (iii) effectively subordinated to any of the Company’s or any guarantor’s existing and future secured indebtedness to the extent of the collateral securing such indebtedness, including the Combined Credit Agreement, and (iv) structurally subordinated to all existing and future liabilities of the Company’s subsidiaries that are not guarantors.

Our obligations under the 5.625% Notes are unsecured and are effectively junior to our secured indebtedness to the extent of the value of the collateral securing such secured indebtedness. Borrowings under the Combined Credit Agreement are secured by substantially all of the assets of the Company, and any existing and future subsidiary guarantors, including all of the capital stock of each restricted subsidiary.

The Company may, at its option, redeem the 5.625% Notes in whole at any time or in part from time to time, on and after August 15, 2024 at a redemption price of 102.813% of the principal amount thereof if redeemed during the twelve-month

period beginning on August 15, 2024, at a redemption price of 101.406% of the principal amount thereof if redeemed during the twelve-month period beginning on August 15, 2025 and at a redemption price of 100% of the principal amount thereof if redeemed on August 15, 2026 and thereafter. Prior to August 15, 2024, the Company may, at its option, redeem some or all of the 5.625% Notes at a price equal to 100% of the principal amount of the 5.625% Notes plus a “make whole” premium and accrued and unpaid interest. The Company may also redeem, at its option, prior to August 15, 2024, up to 40% of the 5.625% Notes with the net proceeds from one or more equity offerings at a redemption price of 105.625% of the principal amount thereof.

If the Company experiences certain kinds of changes of control (as defined in the indenture), holders of the 5.625% Notes may require the Company to repurchase any 5.625% Notes held by them at a price equal to 101% of the principal amount of the 5.625% Notes plus accrued and unpaid interest.

Noncontrolling Interest [Abstract]

Noncontrolling and Redeemable Noncontrolling Interests

Noncontrolling and Redeemable Noncontrolling Interests

When acquiring less than 100% ownership of an entity, the Company may enter into agreements that give the Company an option to purchase, or require the Company to purchase, the incremental ownership interests under certain circumstances. Where the option to purchase the incremental ownership is within the Company’s control, the amounts are recorded as noncontrolling interests in the equity section of the Company’s Unaudited Condensed Consolidated Balance Sheets. Where the incremental purchase may be required of the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity at their estimated acquisition date redemption value and adjusted at each reporting period for changes to their estimated redemption value through Retained earnings (but not less than their initial redemption value), except for foreign currency translation adjustments.

Changes in the Company’s ownership interests in our less than 100% owned subsidiaries during the three and nine months ended September 30, 2021 and 2020 were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,

Redeemable Noncontrolling Interests

The following table presents changes in redeemable noncontrolling interests:

Other	460		—
Ending Balance	$	29,787	$	604

(1) Represents redeemable noncontrolling interests acquired in connection with the acquisition of MDC.

The noncontrolling shareholders’ ability to exercise any such option right is subject to the satisfaction of certain conditions, including conditions requiring notice in advance of exercise and specific employment termination conditions. In addition, these rights cannot be exercised prior to specified staggered exercise dates. The exercise of these rights at their earliest contractual date would result in obligations of the Company to fund the related amounts during 2021 to 2025. It is not determinable, at this time, if or when the owners of these rights will exercise all or a portion of these rights.

The redeemable noncontrolling interest of $29,787 as of September 30, 2021, consists of $14,847, assuming that the subsidiaries perform over the relevant periods at their current profit levels, $14,940 upon termination of such owner’s employment with the applicable subsidiary or death, and $0 representing the initial redemption value (required floor) recorded for certain acquisitions in excess of the amount the Company would have to pay should the Company acquire the remaining ownership interests for such subsidiaries.

These adjustments will not impact the calculation of earnings (loss) per share if the redemption values are less than the estimated fair values. There is no related impact on the Company’s income per share calculations.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

A fair value measurement assumes a transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. The hierarchy for observable and unobservable inputs used to measure fair value into three broad levels are described below: 

•Level 1 - Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

•Level 2 - Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

•Level 3 - Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

Financial Instruments that are not Measured at Fair Value on a Recurring Basis

The following table presents certain information for our financial liability that is not measured at fair value on a recurring basis at September 30, 2021 and December 31, 2020:

	September 30, 2021		December 31, 2020
	Carrying Amount	Fair Value	Carrying Amount	Fair Value
5.625% Notes	1,100,000	1,133,891	—	—

Our long-term debt includes fixed rate debt. The fair value of this instrument is based on quoted market prices in markets that are not active. Therefore, this debt is classified as Level 2 within the fair value hierarchy.

Financial Instruments Measured at Fair Value on a Recurring Basis

The following table presents certain information for our financial instruments that are measured at fair value on a recurring basis at September 30, 2021 and December 31, 2020:

	September 30, 2021				December 31, 2020
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Interest Rate Swap	$	155	$	155	$	416	$	416
Call Options	—		—		360		360
Preferred Shares	—		—		12,033		12,033

The interest rate swap and call options are classified as Level 3 within the fair value hierarchy.

As of December 31, 2020, the Company owned preferred shares in a company called Finn Partners. The preferred shares had a cost basis of $10,000, accrued non-cash dividends, on a cost basis, at a rate of 6% annually. The shares were redeemable to cash in the amount of the cost-plus accrued interest at any time after February 28, 2021 or upon a liquidation event and were also were convertible to common shares of Finn Partners at any time until February 28, 2021 using a conversion ratio of 1% per $1,000 of preferred shares held including accrued dividends. The conversion feature was not bifurcated and was clearly and closely related to the host instrument, preferred shares. Management determined that the preferred shares were a debt-like financial instrument and should be accounted for as available-for-sale securities at their fair value at each reporting period. These preferred shares are considered to be a Level 3 fair value measurement since they utilize unobservable inputs for which there is little or no market data and which require the Company to develop its own assumptions.

On March 11, 2021, the Company transferred all of its ownership in the preferred shares. The Company recognized a gain of $1,200 within Gain on sale of business and other, net on the Unaudited Condensed Consolidated Statements of Operations for the nine months ended September 31, 2021 related to this transaction.

Contingent deferred acquisition consideration (Level 3 fair value measurement) is recorded at the acquisition date fair value and adjusted at each reporting period. The estimated liability is determined in accordance with models of each business' future performance, including revenue growth and free cash flows. These models are dependent upon significant assumptions, such as the growth rate of the earnings of the relevant subsidiary during the contractual period and the discount rate. These growth rates are consistent with the Company’s long-term forecasts. As of September 30, 2021, the discount rate used to measure these liabilities ranged from 3.5% to 5.1%.

As these estimates require the use of assumptions about future performance, which are uncertain at the time of estimation, the fair value measurements presented on the Unaudited Condensed Consolidated Balance Sheets are subject to material uncertainty.

See Note 7 included herein for additional information regarding contingent deferred acquisition consideration.

At September 30, 2021 and December 31, 2020, the carrying amount of the Company’s financial instruments, including cash, cash equivalents, accounts receivable and accounts payable, approximated fair value because of their short-term maturity.

Non-financial Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis

Certain non-financial assets are measured at fair value on a nonrecurring basis, primarily goodwill, intangible assets (Level 3 fair value measurement) and right-of-use lease assets (Level 2 fair value measurement). Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment. The Company did not recognize an impairment of goodwill in the three and nine months ended September 30, 2021 and 2020. The Company did recognize an impairment for intangible assets in the three and nine months ended September 30, 2021 . Refer to Note 14 for further detail.

Segment Reporting [Abstract]

Segment Information

Segment Information

The Company determines an operating segment if a component (i) engages in business activities from which it earns revenues and incurs expenses, (ii) has discrete financial information, and is (iii) regularly reviewed by the Chief Operating Decision Maker (“CODM”), who is Mark Penn, Chief Executive Officer and Chairman, to make decisions regarding resource allocation for the segment and assess its performance. Once operating segments are identified, the Company performs an analysis to determine if aggregation of operating segments is applicable. This determination is based upon a quantitative analysis of the expected and historic average long-term profitability for each operating segment, together with a qualitative assessment to determine if operating segments have similar operating characteristics.

The CODM uses Adjusted EBITDA (defined below) as a key metric, to evaluate the operating and financial performance of a segment, identify trends affecting the segments, develop projections and make strategic business decisions. Adjusted EBITDA is 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.

The Company has three reportable segments as follows: “Integrated Agencies Network,” “Media Network” and the “Communications Network.” In addition, the Company combines and discloses operating segments that do not meet the

aggregation criteria as “All Other.” The Company also reports corporate expenses, as further detailed below, as “Corporate.” All segments follow the same basis of presentation and accounting policies as those described throughout the Notes to the Unaudited Condensed Consolidated Financial Statements included herein.

The Integrated Agencies Networks provide a range of services for their clients, primarily including strategy, creative         and production for advertising campaigns across a variety of platforms (digital, social media, television broadcast and print) as well as public relations and communications services, experiential, social media and influencer marketing. These operating segments share similar characteristics related to (i) the nature of their services; (ii) the type of clients and the methods used to provide services; and (iii) the extent to which they may be impacted by global economic and geopolitical risks. In addition, these operating segments compete with each other for new business and from time to time have business move between them.

•The Media Network reportable segment is comprised of a single operating segment that combines media buying and planning across a range of platforms (out-of-home, paid search, social media, lead generation, programmatic, television broadcast) with technology and data capabilities and includes the Assembly, GALE, MMI Agency, Ink, Multiview, and Kenna brands.

•The Communications Network reportable segment is comprised of a single operating segment that provides advocacy, corporate communications, public relations and other services and includes SKDK, Allison & Partners, and Targeted Victory brands.

•All Other consists of the Company’s our central innovations group, Reputation Defender (sold in September 2021) and infancy stage digital products such as Prophet.

•Corporate consists of corporate office expenses incurred in connection with the strategic resources provided to the operating segments, as well as certain other centrally managed expenses that are not fully allocated to the operating segments. These office and general expenses include (i) salaries and related expenses for corporate office employees, including employees dedicated to supporting the operating segments, (ii) occupancy expenses relating to properties occupied by all corporate office employees, (iii) other office and general expenses including professional fees for the financial statement audits and other public company costs, and (iv) certain other professional fees managed by the corporate office. Additional expenses managed by the corporate office that are directly related to the operating segments are allocated to the appropriate reportable segment and the All Other category.

Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2021

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation.  The accompanying consolidated financial statements include the accounts of Stagwell Inc. and its domestic and international controlled subsidiaries that are not considered variable interest entities, and variable interest entities for which the Company is the primary beneficiary. Intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Use of Estimates.  The preparation of the consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities including goodwill, intangible assets, contingent deferred acquisition consideration, redeemable noncontrolling interests, deferred tax assets, right-of-use assets and the amounts of revenue and expenses reported during the period. These estimates are evaluated on an ongoing basis and are based on historical experience, current conditions and various other assumptions believed to be reasonable under the circumstances. These estimates require the use of assumptions about future performance, which are uncertain at the time of estimation. To the extent actual results differ from the assumptions used, results of operations and cash flows could be materially affected.

Fair Value

Fair Value.  The Company applies the fair value measurement guidance for financial assets and liabilities that are required to be measured at fair value and for non-financial assets and liabilities that are not required to be measured at fair value on a recurring basis, including goodwill, right-of-use assets and other identifiable intangible assets. See Note 13 included herein for additional information regarding fair value measurements.

Concentration of Credit Risk

Concentration of Credit Risk.  The Company provides marketing communications services to clients who operate in most industry sectors. Credit is granted to qualified clients in the ordinary course of business. Due to the diversified nature of the Company’s client base, the Company does not believe that it is exposed to a concentration of credit risk. No client accounted for more than 10% of the Company’s consolidated accounts receivable as of September 30, 2021 or December 31, 2020. No sales to an individual client accounted for more than 10% of revenue for the three and nine months ended September 30, 2021 and 2020.

Cash and Cash Equivalents

Cash and Cash Equivalents.  The Company’s cash equivalents are primarily comprised of investments in overnight interest-bearing deposits, money market instruments and other short-term investments with original maturity dates of three months or less at the time of purchase. The Company has a concentration of credit risk in that there are cash deposits in excess of federally insured amounts and international cash balances may not qualify for foreign government insurance programs. To date, the Company has not experienced any losses on cash and cash equivalents.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts.  Trade receivables are stated at invoiced amounts less allowances for doubtful accounts. The allowances represent estimated uncollectible receivables associated with potential customer defaults usually due to customers’ potential insolvency. The allowances include amounts for certain customers where a risk of default has been specifically identified. The assessment of the likelihood of customer defaults is based on various factors, including the length of time the receivables are past due, historical experience and existing economic conditions. Allowance for doubtful accounts was $5,294 and $5,109  at September 30, 2021 and December 31, 2020, respectively.

Expenditures Billable To Clients

Expenditures Billable to Clients.  Expenditures billable to clients consist principally of outside vendor costs incurred on behalf of clients when providing services that have not yet been invoiced to clients. Such amounts are invoiced to clients at various times over the course of the period.

Fixed Assets

Fixed Assets.  Fixed assets are stated at cost, net of accumulated depreciation. Computers, furniture and fixtures, and capitalized software are depreciated on a straight-line basis over periods of three to ten years. Leasehold improvements are depreciated on a straight-line basis over the lesser of the term of the related lease or the estimated useful life of the asset. Repairs and maintenance costs are expensed as incurred. Accumulated depreciation was $39,357 and $28,365 at September 30, 2021 and December 31, 2020, respectively.

Leases

Leases. Effective January 1, 2019, the Company adopted Accounting Standards Codification, Leases (“ASC 842”). The Company recognizes on the balance sheet at the time of lease commencement a right-of-use lease asset and a lease liability, initially measured at the present value of the lease payments. All right-of-use lease assets are reviewed for impairment. With the adoption of ASC 842, the Company elected to apply the package of practical expedients: (i) whether a contract is or contains a lease, (ii) the classification of existing leases, and (iii) whether previously capitalized costs continue to qualify as initial indirect costs. Additionally, the Company elected the practical expedient to not separate non-lease components from lease components for all operating leases. See Note 8 included herein for further information on leases.

Impairment of Long-lived Assets

Impairment of Long-lived Assets.  A long-lived asset or asset group is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, the Company compares the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of such asset or asset group. If this comparison indicates that there is an impairment, the amount of the impairment is typically calculated using discounted expected future cash flows where observable fair values are not readily determinable. The discount rate applied to these cash flows is based on the Company’s weighted average cost of capital (“WACC”), risk adjusted where appropriate, or other appropriate discount rate.

Goodwill

Goodwill.  Goodwill (the excess of the acquisition cost over the fair value of the net assets acquired) acquired as a result of a business combination which is not subject to amortization is tested for impairment, at the reporting unit level, annually as of October 1st of each year, or more frequently if indicators of potential impairment exist.

For the annual impairment test, the Company has the option of assessing qualitative factors to determine whether it is more likely than not that the carrying amount of a reporting unit exceeds its fair value or performing a quantitative goodwill impairment test. Qualitative factors considered in the assessment include industry and market considerations, the competitive environment, overall financial performance, changing cost factors such as labor costs, and other factors specific to each reporting unit such as change in management or key personnel.

If the Company elects to perform the qualitative assessment and concludes that it is more likely than not that the fair value of the reporting unit is more than its carrying amount, then goodwill is not considered impaired and the quantitative impairment test is not necessary. For reporting units for which the qualitative assessment concludes that it is more likely than not that the fair value of the reporting unit is less than its carrying amount and for reporting units for which the qualitative assessment is not performed, the Company will perform the quantitative impairment test, which compares the fair value of the reporting unit to its carrying amount. If the fair value of the reporting unit exceeds the carrying amount of the net assets assigned to that reporting unit, goodwill is not considered impaired. However, if the fair value of the reporting unit is lower than the carrying amount of the net assets assigned to the reporting unit, an impairment charge is recognized equal to the excess of the carrying amount over the fair value.

Determining the fair value of a reporting unit involves the use of significant estimates and assumptions. The Company uses a combination of the income approach, which incorporates the use of the discounted cash flow (“DCF”) method, and the market approach, which incorporates the use of earnings and revenue multiples based on market data. The Company generally applies an equal weighting to the income and market approaches for the impairment test. The income approach and the market approach both require the exercise of significant judgment, including judgment about the amount and timing of expected future cash flows, assumed terminal value and appropriate discount rates.

The DCF estimates incorporate expected cash flows that represent a spectrum of the amount and timing of possible cash flows of each reporting unit from a market participant perspective. The expected cash flows are developed from the Company’s long-range planning process using projections of operating results and related cash flows based on assumed long-term growth rates, demand trends and appropriate discount rates based on a reporting unit’s WACC as determined by considering the observable WACC of comparable companies and factors specific to the reporting unit. The terminal value is estimated using a constant growth method which requires an assumption about the expected long-term growth rate. The estimates are based on historical data and experience, industry projections, economic conditions, and the Company’s expectations.

Definite Lived Intangible Assets

Definite Lived Intangible Assets.  Definite lived intangible assets are subject to amortization over their useful lives. A straight-line amortization method is used over the estimated useful life which is representative of the pattern of how the economic benefits of the specific intangible asset is consumed. Intangible assets that are subject to amortization are reviewed for potential impairment at least annually or whenever events or circumstances indicate that carrying amounts may not be recoverable. The Company uses an income approach, which incorporates the use of the discounted cash flow (“DCF”) method.

Business Combinations

Business Combinations. Business combinations are accounted for using the acquisition method and accordingly, the assets acquired (including identified intangible assets), the liabilities assumed and any noncontrolling interest in the acquired business are recorded at their acquisition date fair values.

For each acquisition, the Company undertakes a detailed review to identify other intangible assets and a valuation is performed for all such identified assets. The Company uses several market participant measurements to determine the estimated value. This approach includes consideration of similar and recent transactions, as well as utilizing discounted expected cash flow methodologies. A substantial portion of the intangible assets value that the Company acquires is the specialized know-how of the workforce, which is treated as part of goodwill and is not required to be valued separately. The majority of the value of the identifiable intangible assets acquired is derived from customer relationships, including the related customer contracts, as well as tradenames and trademarks.

Deferred Acquisition Consideration

Deferred Acquisition Consideration. Certain acquisitions include an initial payment at the time of closing and provide for future additional contingent purchase price payments. Contingent purchase price obligations for these transactions are recorded as deferred acquisition consideration liabilities on the balance sheet, at the acquisition date fair value and are remeasured at each reporting period. These liabilities are derived from the projected performance of the acquired entity. These arrangements may be dependent on future events, such as the growth rate of the earnings of the relevant subsidiary during the contractual period. At each reporting date, the Company models each business’ future performance, including revenue growth and free cash flows, to estimate the value of each deferred acquisition consideration liability. The liability is adjusted quarterly based on changes in current information affecting each subsidiary’s current operating results and the impact this information will have on future results included in the calculation of the estimated liability. These adjustments are recorded in the results of operations. In instances where such contingent payments require the sellers’ continuous employment with the Company after the transaction, they are recorded as compensation expense in the Unaudited Condensed Consolidated Statements of Operations.

Redeemable Noncontrolling Interest

Redeemable Noncontrolling Interests. Many of the Company’s acquisitions include contractual arrangements where the noncontrolling shareholders have an option to purchase, or may require the Company to purchase, such noncontrolling shareholders’ incremental ownership interests under certain circumstances. The Company typically has similar call options under the same contractual terms. The amount of consideration under these contractual arrangements is not a fixed amount, but rather is dependent upon various valuation formulas, such as the average earnings of the relevant subsidiary through the date of exercise or the growth rate of the earnings of the relevant subsidiary during that period. In the event that an incremental purchase may be required by the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity on the Unaudited Condensed Consolidated Balance Sheets at their acquisition date fair value and adjusted for changes to their estimated redemption value through Retained earnings or Paid-in capital (when at an accumulated deficit) in the Unaudited Condensed Consolidated Balance Sheets (but not less than their initial redemption value), except for foreign currency translation adjustments. These adjustments will not impact the calculation of earnings (loss) per share if the redemption values are less than the estimated fair values.

Subsidiary and Equity Investment Stock Transactions

Subsidiary and Equity Investment Stock Transactions. Transactions involving the purchase, sale or issuance of interests of a subsidiary where control is maintained are recorded as a reduction in the redeemable noncontrolling interests or noncontrolling interests, as applicable. Any difference between the purchase price and noncontrolling interest is recorded to Common stock and other paid-in capital in the Unaudited Condensed Consolidated Balance Sheets. In circumstances where the purchase of shares of an equity investment results in obtaining control, the existing carrying value of the investment is remeasured to the acquisition date fair value and any gain or loss is recognized in the results of operations.

Revenue Recognition

Revenue Recognition.  The Company’s revenue is recognized when control of the promised services are transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. See Note 5 included herein for additional information.

Cost of Services Sold

Cost of Services.  Cost of services sold primarily consists of staff costs that are directly attributable to the Company’s client engagements, as well as third-party direct costs of production and delivery of services to its clients. Cost of services sold does not include depreciation, amortization, and other office and general expenses that are not directly attributable to the Company’s client engagements.

Interest Expense

.  The Company uses the effective interest method to amortize deferred financing costs and any original issue premium or discount, if applicable. The Company also uses the straight-line method, which approximates the effective interest method, to amortize the deferred financing costs on the Credit Agreement.

Income Taxes

Income Taxes. We account for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates and laws expected to be in effect when the differences are expected to reverse. The Company records associated interest and penalties as a component of income tax expense. The Company records a valuation allowance against deferred income tax assets when management believes it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Management evaluates on a quarterly basis all available positive and negative evidence considering factors such as the reversal of deferred income tax liabilities, taxable income in eligible carryback years, projected future taxable income, the character of the income tax asset, tax planning strategies, changes in tax laws and other factors. The periodic assessment of the net carrying value of the Company’s deferred tax assets under the applicable accounting rules requires significant management judgment. A change to any of these factors could impact the estimated valuation allowance and income tax expense.

Share-based Compensation

Stock-Based Compensation.  Under the fair value method, compensation cost is measured at fair value at the date of grant and is expensed over the service period, generally the award’s vesting period. The Company uses its historical volatility derived over the expected term of the award to determine the volatility factor used in determining the fair value of the award. The Company recognizes forfeitures as they occur.

Stock-based awards that are settled in cash or equity at the option of the Company are recorded at fair value on the date of grant. The fair value measurement of the compensation cost for these awards is based on using the Black-Scholes option

pricing-model or other acceptable method and is recorded in Operating income over the service period, in this case the award’s vesting period.The Company has adopted the straight-line attribution method for determining the compensation cost to be recorded during each accounting period. The Company commences recording compensation expense related to awards that are based on performance conditions under the straight-line attribution method when it is probable that such performance conditions will be met.

Income (Loss) per Common Share

Income (Loss) per Common Share.  Basic income (loss) per common share is based upon the weighted average number of common shares outstanding during each period. Diluted income (loss) per common share is based on the above, in addition, if dilutive, common share equivalents, which include outstanding options, stock appreciation rights, and unvested restricted stock units. In periods of net loss, all potentially issuable common shares are excluded from diluted net loss per common share because they are anti-dilutive.

Foreign Currency Translation

Foreign Currency Translation.  The functional and reporting currency of the Company is the US dollar. Generally, the Company’s subsidiaries use their local currency as their functional currency. Accordingly, the currency impacts of the translation of the Unaudited Condensed Consolidated Balance Sheets of the Company and its non-U.S. dollar based subsidiaries to U.S. dollar statements are included as cumulative translation adjustments in Accumulated other comprehensive income (loss). Translation of intercompany debt, which is not intended to be repaid, is included in cumulative translation adjustments. Cumulative translation adjustments are not included in net income (loss) unless they are actually realized through a sale or upon complete, or substantially complete, liquidation of the Company’s net investment in the foreign operation. Translation of current intercompany balances are included in net income (loss). The balance sheets of non-U.S. dollar based subsidiaries are translated at the period end rate. The Unaudited Condensed Consolidated Statements of Operations of the Company and its non-U.S. dollar based subsidiaries are translated at average exchange rates for the period.

Gains and losses arising from the Company’s foreign currency transactions are reflected in Foreign exchange, net on the Consolidated Statements of Operations.

New Accounting Pronouncements

In October 2021, the FASB issued ASU 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the recognition of an acquired contract liability and other items. ASU 2021-08 is effective January 1, 2023; however, the Company has early adopted the standard and retrospectively applied it to the financial statements herein.

In March 2020, the FASB issued ASU 2020-04, and in January subsequently issued ASU 2021-01, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, to provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 is effective upon issuance, through December 31, 2022. The Company is evaluating the impact of the adoption of this guidance on the Company's financial statements and disclosures.

Numerator:
Net loss attributable to Stagwell Inc. common shareholders	$ (4,545)	$ (4,545)

Anti-dilutive:
Class C shares	179,970,051	179,970,051
Stock Appreciation Rights and Restricted Awards	6,596,023	6,596,023

There were 123,849,000 Preferred Shares outstanding which were convertible into 33,035,446 of Class A common shares at September 30, 2021. These Preferred Shares were anti-dilutive for each period presented in the table above and are therefore excluded from the diluted earnings per share calculation.

The combination of MDC and SMG was completed on August 2, 2021, which was treated as a reverse acquisition for financial reporting purposes. SMG was treated as the accounting acquirer and MDC was the accounting acquiree. Therefore, under applicable accounting principles, the historical financial results of SMG prior to August 2, 2021 are considered our historical financial results. Accordingly, historical information presented in this Form 10-Q for events occurring or periods ending before August 2, 2021 does not reflect the impact of the Transactions or the financial results of MDC and may not be comparable with historical information for events occurring or periods ending on or after August 2, 2021.

SMG’s equity structure, prior to the combination with MDC, was a non-unitized single member limited liability company, resulting in all components of equity attributable to the member being reported within Members' Capital. Given that SMG was a non-unitized single member limited liability company, net income (loss) prior to the combination is not applicable for purposes of calculating earnings per share. Therefore, the net income (loss) in the table above includes the income or loss for the period beginning on the acquisition date through the end of the respective reporting period and as such will not reconcile to the respective amounts presented within the Unaudited Condensed Consolidated Statements of Operations.
