Chief executive Andy Wood said the company was "mindful" of the challenges facing the on-trade.
"We fundamentally believe that pubs have a unique and important place in communities and their continued closure rate remains troubling," he said.
"When allied to the significant competitive pressures they face, this is something that we cannot ignore. We held Adnams beer prices during the period 2009 to 2014 and, with such things as fuel prices at their lowest level for years, feel it is appropriate to do so once again."
Other leading brewers, including Molson Coors, Heineken and Diaego, angered licensees after announcing they would be increasing their 2016 wholesale beer prices.
Representatives from all three companies said a 'need for investment' was behind the price hikes and said they had been kept to the 'minimum level'.
Frustrated publicans have pointed to lower fuel prices and input costs meaning there is no need for brewers to raise prices, and argued consumers are becoming increasingly fed-up with the rising cost of a pint.
The British Beer and Pub Association and the Campaign for Real Ale are pushing for a fourth successive cut in beer duty in March’s Budget.
