MDC Partners, parent to PR units like Allison + Partners and Kwittken + Company, reported third quarter revenue climbed 8.7% to $289M on strong organic growth (+9.3%) and net new business wins (+$34.2M).

Net loss grew to $19.3M from $13.2M a year earlier.

Chairman and CEO Miles Nadal said a robust new business pipeline led the company to raise guidance for the rest of the year. He sees a "runway" for growth as MDC only has a 3% market share in North America and is "in the very early stages of building an international business."

In a conference call, Nadal singled out Doner, Allison Partners, Anomaly, Kwittken, KBS and CPB for "exceptional work."

MDC's strategic marketing services segment, which includes PR, was up 15.5% to $203.4M.

MDC shares are trading just under a 52-week high of $30.76 and the company announced a three-for-two split on Nov. 22.
