MDC's strategic marketing services group, which includes its PR and ad agencies, jumped more than 21% to $200.7M in Q4 revenue and was up nearly 19% for the year to $721.2M. MDC's PR units include Sloane & Company, Allison + Partners and Kwittken + Co.

Chairman and CEO Miles Nadal called 2012 an "exceptional year" as the company beat guidance and showed strong revenue gains and growth. CFO David Doft added that a work to improve MDC's balance sheet is paying off.

For the full year, organic growth hit 8.4% while revenue increased 12.9% to nearly $1.1B. Net loss ticked up to $79.4M for the year, up from $76.3M in 2011.

Net new business wins totaled $136.9M for 2012. "We are winning incremental share of wallet and gaining market share," said Nadal.

MDC forecasts 2013 growth from 5.1-7.4% with revenue topping $1.1B.
