MDC PARTNERS INC. REPORTS RESULTS FOR THE THREE MONTHS ENDED
MARCH 31, 2020 

Company's Strategic Plan Delivering Significant Performance Improvements on Key Metrics

FIRST QUARTER HIGHLIGHTS:

New York, NY, April 29, 2020 (NASDAQ: MDCA) – MDC Partners Inc. (“MDC Partners” or the “Company”) today announced financial results for the three months ended March 31, 2020.

“MDC delivered significant improvements in the first quarter of 2020, returning to organic growth of 2%, nearly doubling Adjusted EBITDA, and boosting margins 560 basis points,” said Mark Penn, Chairman and Chief Executive Officer of MDC Partners. “These results were game-changing for us in terms of implementing our New World Strategy, putting us in a much stronger position to manage through the pandemic that has enveloped the economy and the world. Many of the changes we made last year are reflected in our results over the last two quarters as our plans have been realized.”

“We are operating on the basis of safety first and business second as we act to safeguard our people and advance our business in a radically new environment. Our agencies have adapted well to the new work from home policies and delivered significant new campaigns for clients as we help them navigate through these uncertain times with the best in cloud-based production tools and data-based creativity.”

“Our efforts to reform and reshape MDC in the last year at all levels and to create a more cohesive, collaborative and efficient organization position us well to navigate this crisis now and prepare us for eventual recovery,” Mr. Penn added.

Frank Lanuto, Chief Financial Officer, added, “Our new network structure and our cost-savings initiatives paid off in the first quarter, with significant improvements over the prior year period across our income statement and balance sheet. We ended the first quarter with a solid cash balance and reduced leverage from year end, down to 4.3x. We remain deeply committed to addressing all our clients’ needs going forward and continuing to reduce costs in response to current market conditions.”

First Quarter and Year-to-Date 2019 Financial Results

Revenue for the first quarter of 2020 was $327.7 million versus $328.8 million for the first quarter of 2019, a decline of 0.3%. The effect on revenue of foreign exchange due to the strong US Dollar was negative 0.5%, the impact of non-GAAP acquisitions (dispositions), net was negative 1.7%, and organic revenue was positive 2.0%. Organic revenue was unfavorably impacted by 7 basis points from higher billable pass-through costs incurred on clients’ behalf from certain of our partner firms acting as principal.

Net New Business wins in the first quarter of 2020 totaled $8.4 million.

Net loss attributable to MDC Partners common shareholders for the first quarter of 2020 was $2.4 million versus a net loss of $2.5 million for the first quarter of 2019. This improvement was primarily due to a decline in expenses principally driven by a reduction in staff costs offset by the change in foreign exchange gain and losses. Diluted loss per share attributable to MDC Partners common shareholders for the first quarter of 2020 was $0.03 versus diluted loss per share of $0.04 for the first quarter of 2019.

Adjusted EBITDA for the first quarter of 2020 was $39.6 million versus $21.5 million for the first quarter of 2019, an increase of 84.3%. The increase was primarily driven by a reduction in staff costs, partially offset by a decline in revenues. This led to a 560 basis point increase in Adjusted EBITDA margin in the first quarter of 2020 to 12.1% from 6.5% in the first quarter of 2019. Excluding the impact of the Kingsdale and Sloane divestitures, Adjusted EBITDA increased 110.1% in the first quarter of 2020 compared with the prior year period.

Net loss attributable to MDC Partners common shareholders for the last twelve months (LTM) was $17.2 million as of March 31, 2020 versus a $17.3 million loss as of December 31, 2019.

Covenant EBITDA for the last twelve months (LTM) was $200.7 million at March 31, 2020 versus $180.5 million at December 31, 2019, an increase of 11.2%. The change was primarily driven by the increase in Adjusted EBITDA.

Financial Outlook

Given the uncertainties in the global business environment arising from the COVID-19 pandemic, the Company is not providing a 2020 outlook for Revenue and Covenant EBITDA at this time.

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, 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 measure that represents operating profit plus depreciation and amortization, stock-based compensation, deferred acquisition consideration adjustments, distributions from non-consolidated affiliates, and other items.

(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. Pro forma adjustments for our real estate consolidation to our new headquarters at 1 World Trade Center (“1WTC”) are calculated to include the lease expense recognized as of the first period required by US GAAP for 1WTC and excluding the future costs of all leases that will either be terminated or sublet as permitted dispositions in connection with the relocation. 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.

•         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;

19 DEFINITION OF NON - GAAP MEASURES In addition to its reported results, MDC Partners has included in its earnings release and supplemental management presentati on certain financial results that the Securities and Exchange Commission defines as "non - GAAP financial measures." Management believes that such non - GAAP financial measures, when r ead in conjunction with the Company's reported results, can provide useful supplemental information for investors analyzing period to period comparisons of the Com pan y's results. Such non - GAAP financial measures include the following: Organic Revenue: Organic Revenue: “Organic revenue growth” and “organic revenue decline” refer to the positive or negative results, respective l y, of subtracting both the foreign exchange and acquisition (disposition) components from total revenue growth. The acquisition (disposition) component is calcu lat ed 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 org ani c revenue growth (decline) component reflects the constant currency impact of (a) the change in revenue of the partner firms which the Company has held throughout each of the com parable 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 acquisitions as if the acquisition had been owned during the equivalent period in the prior year and (ii) for acquisitions during the previous year, th e 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 - acquis ition revenues for the applicable periods, and (iii) for dispositions, the revenue effect from such dispositions as if they had been disposed of during the equivalent period in the p rio r year. Net New Business: Estimate of annualized revenue for new wins less annualized revenue for losses incurred in the period. Adjusted EBITDA: Adjusted EBITDA is a non - GAAP measure that represents operating profit (loss) plus depreciation and amortization, stock - based co mpensation, deferred acquisition consideration adjustments, distributions from non - consolidated affiliates, and other items. Covenant EBITDA : Covenant EBITDA is a measure that includes pro forma adjustments for acquisitions, one - time charges, permitted dispositions an d other items, as defined in the Credit Agreement. Pro forma adjustments for our real estate consolidation to our new headquarters at 1 World Trade Center (“1 WTC ”) are calculated to include the lease expense recognized as of the first period required by US GAAP for 1WTC and excluding the future costs of all leases that will either be terminated or sublet as permitted dispositions in connection with the relocation. We believe that the presentation of Covenant EBITDA is useful to investors as it eliminates t he 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 additio nal information to investors about the calculation of, and compliance with, certain financial covenants in the Credit Agreement. Included in the Company’s earnings release and supplemental management presentation are tables reconciling MDC Partners’ repo rte d results to arrive at certain of these non - GAAP financial measures. Note: A reconciliation of non - GAAP to US GAAP reported results has been provided by the Company in the tables included herein.
