DEFINITION OF NON-GAAP FINANCIAL MEASURES In addition to its reported results, MDC Partners has included in its earnings release and supplemental management presentation certain financial results that the Securities and Exchange Commission 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: Organic Revenue: 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 which 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 acquisitions 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 dispositions as if they had been disposed of during the equivalent period in the prior 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 financial measure that represents Net income (loss) attributable to MDC Partners Inc. common shareholders plus or minus adjustments 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 severance expense 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. 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 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 Credit Agreement. Included in the Company’s earnings release and supplemental management presentation are tables reconciling MDC Partners’ reported 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. 22
