PRESS RELEASE

MDC PARTNERS INCREASES GUIDANCE FOR FISCAL YEAR 2012

NEW YORK, NY (April 4, 2012) – MDC Partners Inc. (“MDC Partners” or the “Company”) today announced increased financial guidance for Fiscal Year 2012.

Miles S. Nadal, Chairman and Chief Executive Officer of MDC Partners, said, “Our business has been performing very well in 2012 thus far. We have won some significant pieces of business, completed three strategic investments that are highly accretive, and entered into a joint venture in Brazil, further enhancing our ability to service multinational clients with a sustainable point of differentiation.

“These strategic investments enhance our creative, digital and analytics market leadership. We now have a formidable, scaled media platform under the Maxxcom Global Media umbrella. Of significant importance is that all of these initiatives have enhanced the overall financial performance of MDC Partners on all significant metrics, benefitting our income statement, balance sheet and our statement of cash flows.

“As a result, we are increasing our financial guidance for 2012. Revenue guidance is increasing by $50 million to a range of $1.05 billion to $1.075 billion, an increase of +11.3% to +14.0% year over year. EBITDA guidance is increasing by $8 million to a range of $110 million to $115 million, an increase of +21.2% to +26.7% year over year. Free Cash Flow guidance is increasing by $7 million to a range of $35 million to $40 million, an increase of +50.8% to +72.3% year over year. EBITDA margins in 2012 are now expected to expand by a range of +90 basis points to +110 basis points versus 2011 to 10.5% to 10.7%, an incremental +30 basis points versus our initial expectations for the year.”

“We are more enthusiastic about the prospects for improved financial performance going forward,” said David Doft, Chief Financial Officer. “From a balance sheet perspective, we ended the first quarter with approximately $5-10 million of excess cash, zero net borrowings under our $150 million credit facility and total net debt below $340 million. This net debt position represents our lowest number in approximately a year and a half despite the dramatic increase in the scale and profitability of our business and given the recent transactions. We are confident that we can achieve a 2012 year-end leverage ratio of between 3.0 and 3.5 times EBITDA and between 2.5 and 3.0 times EBITDA in 2013. We believe that MDC’s strategic and financial positioning will enable us to drive significantly enhanced shareholder value in 2012 and beyond.”

Updated guidance for 2012 is as follows:

MDC Partners Announces $0.28 per Share Cash Dividend

MDC Partners today also announced that its Board of Directors has declared a cash dividend of $0.28 per share on all of its outstanding Class A shares and Class B shares. The semi-annual dividend will be payable on or about May 22, 2012 to shareholders of record at the close of business on May 8, 2012.

“We are changing our dividend policy to pay a semi-annual dividend in order to account for and balance the seasonality of MDC’s cash flows from operations,” said Mr. Nadal. “Our intention is to keep the annual dividend rate the same at $0.56 per share. MDC management continues to believe that a growing dividend over time is an important driver of shareholder value and can be achieved in conjunction with our commitment to reducing the overall balance sheet leverage of the company.”

This press release contains forward-looking statements. The Company’s representatives may also make forward-looking statements orally from time to time. Statements in this press release that are not historical facts, including statements about the Company’s beliefs and expectations, earnings guidance, recent business and economic trends, potential acquisitions, estimates of amounts for deferred acquisition consideration and “put” option rights, 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. 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:

The Company’s business strategy includes ongoing efforts to engage in material 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, from borrowings under its credit facility and through incurrence of bridge or other debt financing, any 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 material 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.
