NEW YORK, NY (October 27, 2010) – MDC Partners Inc. (“MDC Partners” or the “Company”) today announced financial results for the three and nine months ended September 30, 2010.

Note: The “Pro Forma 2010 Estimate” section of the above table accounts for recent acquisitions as if financial contributions to MDC occur for the entirety of 2010.

Consolidated revenue for the third quarter of 2010 was $178.6 million, an increase of 32.9% compared to $134.4 million in the third quarter of 2009. EBITDA (as defined) for the third quarter of 2010 was $20.4 million compared to $20.2 million in the third quarter of 2009, which was negatively impacted by revenue that was expected to be recognized in the third quarter but is now expected to be recognized in the fourth quarter, as well as higher costs associated with an increasing number of new business pitches. Net income (loss) attributable to MDC Partners Inc. in the third quarter was a loss of ($10.9) million compared to nominal income in the third quarter of 2009. Diluted earnings (loss) per share from continuing operations attributable to MDC Partners Inc. common shareholders for the third quarter of 2010 was a loss of ($0.36) compared with $0.00 per share in the same period of 2009. Free cash flow from operations (as defined) was $8.5 million in the third quarter of 2010, compared with $14.0 million in the third quarter of 2009. Total free cash flow (equal to free cash flow, as defined, plus changes in working capital and other changes in cash) increased 12.0% to $38.9 million in the third quarter of 2010 from $34.7 million in the same quarter last year.

For the nine months ended September 30, 2010 consolidated revenue was $484.4 million, an increase of 22.5% compared to $395.6 million in the same period of 2009. EBITDA (as defined) for the first nine months of 2010 was $47.9 million, a decrease of 5.7% compared to $50.8 million in the first nine months of 2009.  Net income (loss) attributable to MDC Partners Inc. for the first nine months of 2010 was a loss of ($26.9) million compared to income of $0.1 million in the first nine months of 2009. Diluted earnings (loss) per share from continuing operations attributable to MDC Partners Inc. common shareholders for the nine months ended September 30, 2010 was a loss of ($0.91) compared with income of $0.03 per share in the same period of 2009.

“Our unique business model has enabled us to deliver superior financial performance in a disciplined manner with a conservative approach to our balance sheet,” said David Doft, Chief Financial Officer.  “Organic growth is accelerating and we fully expect that this trend will continue for the remainder of 2010 and for 2011 as well.  Importantly, our recent acquisitions, all of which are accretive and fully integrated into our network, are performing on or ahead of plan, which will drive material incremental returns going forward.  Finally, we expect to deliver even better financial results in 2011 in terms of organic growth, margin expansion and free cash flow generation, especially as we get the full benefit of the recent acquisitions.”

MDC Partners Announces $0.13 per Share Cash Dividend

MDC Partners today also announced that its Board of Directors has declared a cash dividend of $0.13 per share on all of its outstanding Class A shares and Class B shares. The dividend will be payable on or about November 26, 2010 to shareholders of record at the close of business on November 12, 2010.

“We are dedicated to rewarding all of our shareholders for their loyalty and commitment,” said Mr. Nadal. “The payment of cash dividends remains an important part of our ongoing strategy to maximize shareholder value. The new dividend of $0.13 per share represents an 18.2% increase above MDC Partners’ last dividend payment and is representative of the significant increase in free cash flow that MDC has achieved to date. As total free cash flow continues to increase over time, we expect dividend payments to continue to increase as well while still having ample capital available to finance our growth initiatives.”

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 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. These non-GAAP financial measures relate to: (1) presenting EBITDA and EBITDA margin (as defined) for the three and nine months ended September 30, 2010 and 2009; and (2) presenting Total Free Cash Flow, Free Cash Flow and Free Cash Flow per Share (as defined) for the three and nine months ended September 30, 2010 and 2009.  Included in this earnings release are tables reconciling MDC’s reported results to arrive at these non-GAAP financial measures.

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, 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:

· risks associated with severe effects of national and regional economic downturn;

· the Company’s ability to attract new clients and retain existing clients;

· the 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 payment obligations when due and payable, including but not limited to those relating to “put” option right and deferred acquisition consideration;

· the successful completion and integration of acquisitions which complement and expand the Company’s business capabilities; and

· foreign currency fluctuations.

In addition to improving organic growth for its existing operations, 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 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 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.
