1 FORWARD LOOKING STATEMENTS & OTHER INFORMATION This presentation, including our “ 2018 Financial Outlook”, contains forward - looking statements . The Company’s representatives may also make forward - looking statements orally from time to time . Statements in this presentation that are not historical facts, including statements about the Company’s beliefs and expectations, earnings guidance, 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 below . 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 severe effects of international, national and regional economic conditions ; • the Company’s ability to attract new clients and retain existing clients; • the spending patterns and financial success of the Company’s clients; • the Company’s ability to retain and attract key employees; • the Company’s ability to remain in compliance with its debt agreements and the Company’s ability to finance its contingent pa yme nt 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 compliment and expand the Company’s business capabilities; • foreign currency fluctuations; and • risks associated with the ongoing Canadian class litigation claim. The Company’s business strategy includes ongoing efforts to engage in acquisitions of ownership interests in entities in the marketing communications services industry . The Company intends to finance these acquisitions by using available cash from operations and through incurrence of bridge or other debt financing, either of which may increase the Company’s leverage ratios, or by issuing equity, which may have a dilutive impact on existing shareholders proportionate ownership . At any given time the Company may be engaged in a number of discussions that may result in one or more acquisitions . These opportunities require confidentiality and may involve negotiations that require quick responses by the Company . Although there is uncertainty that any of these discussions will result in definitive agreements or the completion of any transactions, the announcement of any such transaction may lead to increased volatility in the trading price of the Company’s securities . Investors should carefully consider these risk factors and the additional risk factors outlined in more detail in the Annual Report on Form 10 - K under the caption “Risk Factors” and in the Company’s other SEC filings .

In addition, a $66.4 million benefit from the reversal of a valuation allowance was due to favorable tax law changes. 2 Reflects a benefit of $105.5 million from the reversal of a valuation allowance on our remaining deferred tax assets, primari ly based on our current and historical taxable income and our expectations of future taxable income.

21 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 m easures, when read in conjunction with the Company's reported results, can provide useful supplemental information for investors analyzing period t o p eriod 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, respective l y, of subtracting both the foreign exchange and acquisition (disposition) components from total revenue growth. The acquisition (disposition) c omp onent is calculated by aggregating prior period revenue for any acquired businesses, less the prior period revenue of any businesses that were dispo sed 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 fir ms 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 acquisition as if the acquisition had been owned durin g t he 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 durin g t hat 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. 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 compensation, deferred acquisition consideration adjustments, distributions from non - consolidated affiliates, and other items. P rior to 2017, Adjusted EBITDA included an additional adjustment for acquisition deal costs. Beginning with 2017, on a prospective basis we no longer includ e t he acquisition deal cost adjustment but we continue to disclose this metric for your reference. 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. We are unable to reconcile our projected 2017 organic revenue growth to the corresponding GAAP measure because we are unable to predict the 2017 impact of foreign exchange due to the unpredictability of future changes in foreign exchange r ate s and because we are unable to predict the occurrence or impact of any acquisitions, divestitures or other potential changes. We are unable to reconcile ou r p rojected 2017 increase in Adjusted EBITDA margin to the corresponding GAAP measure because the amount and timing of many future charges that impact these measur es (such as amortization of future acquired intangible assets, foreign exchange transaction gains or losses, impairment charges, and provision or benefit fo r income taxes) are variable, uncertain, or out of our control and therefore cannot be reasonably predicted without unreasonable effort, if at all. As a re sul t, we are unable to provide reconciliations of these measures. In addition, we believe such reconciliations could imply a degree of precision that might be confusing or misleading to investors. Note: A reconciliation of non - GAAP to US GAAP reported results has been provided by the Company in the tables included in the earnings release issued on February 22, 2018.
