LONDON—FTI Consulting saw its strategic communications revenues increase by just 0.6% in 2016 to more than $191 million.

But the firm saw healthy growth in the fourth quarter, with revenues up 3.2% to $50.3 million compared to $48.8 million in Q4 of 2015, and numbers were dragged down by currency fluctuations. Excluding FX, overall growth would have been 4.5% and fourth quarter growth would have been 8.8%.

While the firm is best known for its work in financial communications, and mergers and acquisitions market in particular (it ranked in the top three M&A advisory firms for 2016), much of the growth in 2016 came from areas such as public affairs—where the Brexit vote in the UK and the Trump election victory in the US have put companies on alert—and employee engagement, areas where FTI has been expanding its capabilities.

The strategic communications operation—which accounts for a little more than 10 percent of revenues—made a strong contribution to the management consulting firm’s overall financials: overall revenues declined slightly in Q4.
