The gambling company in November raised its full-year core earnings (EBITDA) forecast to a range of 390-405 million pounds from a previous range of 365-385 million citing a boost in the sterling value of its euro revenue, last year's merger and favourable sporting results.

However results favoured punters across the industry in the fourth quarter, which the Dublin-headquartered firm said cost it around 40 million pounds before gamblers bet with any winnings, including a 5 million pound loss on the U.S. presidential election.

"This outcome disguises a better underlying performance than we were forecasting," Davy Stockbrokers analyst David Jennings, who had expected EBITDA of 408.8 million pounds, wrote in a note.

"From analysing the statement, we estimate that had results been "normal", EBITDA for the year would have landed north of 420 million pounds."

Online betting exchange Betfair and Paddy Power, which has a chain of shops as well as an online business, said its online revenue fell 3 percent but were up 18 percent in its Australian business, which Jennings said bode well for 2017.

Rival William Hill said this month that its annual profits would fall to the bottom of its forecast range while the recently merged Ladbrokes Coral Group said it would meet its guidance.
