New York, NY, May 5, 2021 (NASDAQ: MDCA) – MDC Partners Inc. (“MDC Partners” or the “Company”) today announced financial results for the three months ended March 31, 2021.
"MDC delivered its highest net income in nearly three years and $52 million of Adjusted EBITDA in the first quarter, up 31% from prior year and the strongest first quarter Adjusted EBITDA result in the company’s history,” said Mark Penn, Chairman and Chief Executive Officer of MDC Partners. “We continue to see a rebound from pandemic revenue lows, with year-over-year revenue growth in the Healthcare, Consumer Products and Financial client sectors. We are encouraged by the strong start to the year and maintain our outlook of 7 to 9% organic revenue growth for the year with Adjusted EBITDA of $190 million to $200 million. This momentum sets us up well for the next major step in our strategic transformation, the proposed combination of MDC and Stagwell, which we believe promises to disrupt the industry and provide value for all our stakeholders.”
Frank Lanuto, Chief Financial Officer, added, “As our revenue rebounds from pandemic declines, we again delivered expanded Adjusted EBITDA margins to 16.9%, up 480 basis points from a year ago. We continued to lower our leverage, down to 4.1x, and generated $47 million in cash flow from operations in the quarter, ending with net cash of $93 million."
First Quarter 2021 Financial Results
Revenue for the first quarter of 2021 was $307.6 million versus $327.7 million for the first quarter 2020, a decline of 6.2%. The effect on revenue of foreign exchange was positive 1.4%, the impact of non-GAAP acquisitions (dispositions), net was negative 0.6%, and organic revenue decline was 6.9%, inclusive of $16.9 million or 481 basis points from lower billable costs. Organic revenue declined primarily due to reduced spending by clients in connection with COVID-19.
Revenue in the first quarter of 2021 decreased 6.3% sequentially from the fourth quarter of 2020, less than the typical seasonal decline as revenue continues to rebound from COVID-19 declines. Net New Business wins in the first quarter of 2021 totaled $10.2 million.
Net income attributable to MDC Partners Inc. common shareholders for the first quarter of 2021 was $0.9 million versus net loss of $2.4 million for the first quarter 2020. The increase was primarily due to lower revenues, more than offset by a reduction in expenses, as well as the favorable impact of foreign exchange. D iluted income per share attributable to MDC Partners common shareholders for the first quarter of 2021 was $0.01 versus diluted loss per share of $0.03 f or the first quarter 2020.
Adjusted EBITDA for the first quarter of 2021 was $51.9 million versus $39.6 million for the first quarter 2020, an increase of 31.3%, primarily due to lower revenues, more than offset by a reduction in expenses to combat the impact of COVID-19 on the business. This led to a 480 basis point increase in Adjusted EBITDA margin in the first quarter of 2021 to 16.9% from 12.1% in the first quarter 2020.
Covenant EBITDA for the last twelve months (LTM) was $200.7 million as of March 31, 2021, up from $190.1 million in the fourth quarter of 2020 and flat versus the first quarter of 2020.

Non-GAAP Financial Measures
In addition to its reported results, MDC Partners has included in this earnings release certain financial results that the Securities and Exchange Commission (SEC) defines as "non-GAAP Financial Measures." Management believes that such non-GAAP financial measures, when read in conjunction with the Company's reported results,
Page 3

can provide useful supplemental information for investors analyzing period to period comparisons of the Company's results. Such non-GAAP financial measures include the following:
(1) Organic 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.
(2) Net New Business: Estimate of annualized revenue for new wins less annualized revenue for losses incurred in the period.
(3) Adjusted EBITDA: Adjusted EBITDA is a non-GAAP financial measure that represents Net income (loss) attributable to MDC Partners Inc. common shareholders plus or minus non-operating items to operating income (loss) plus depreciation and amortization, stock-based compensation, deferred acquisition consideration adjustments, distributions from non-consolidated affiliates, and other items, net which includes items such as merger related costs, severance and other restructuring expenses, including costs for leases that will either be terminated or sublet in connection with the centralization of our New York real estate portfolio.
(4) Covenant EBITDA: Covenant EBITDA is a measure that includes pro forma adjustments for acquisitions, one-time charges, permitted dispositions and other items, as defined in the Company's Credit Agreement. We believe that the presentation of Covenant EBITDA is useful to investors as it eliminates the effect of certain non-cash and other items not necessarily indicative of a company’s underlying operating performance. In addition, the presentation of Covenant EBITDA provides additional information to investors about the calculation of, and compliance with, certain financial covenants in the Company's Credit Agreement.
Included in this earnings release are tables reconciling MDC Partners’ reported results to arrive at certain of these non-GAAP financial measures.

•adverse tax consequences in connection with the Proposed 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 tax attributes may result in increased tax costs;
