The digital marketing and communications company saw pre-tax profit rise to £24.2mln in the year to 31 January 2017 from £16.1mln the previous year.
Revenue edged up 32% to £171.0mln from £129.8mln, with organic growth of 10%, driven by US businesses.
The strong performance in the US division was led by its Text 100, Beyond, OutCast, M Booth, Connections Media and Bite agencies.
In the UK, the company improved the efficiency of its businesses to offset the slump in sterling.
Next bought the Publitek, Pinnacle and Twogether agencies, which it said are high margin and high growth businesses. It also acquired London-based market research agency, HPI, which has been merged with Morar to create MIG Global.
Cash generated from operations jumped 101% to £32.8mln from £16.3mln, bolstered by management of working capital. Net debt rose to £11.4mln from £6.6mln.
In March 2016 the company entered into a new extended four-year £30mln revolving credit facility with HSBC to fund acquisitions. The facility will be repaid using trading cash flows.
“The results for the financial year to January 2017 were helped by forex, but reflect strong organic growth, judicious and effective acquisitions and continued organisational efficiencies in an entrepreneurial culture,” said Next chairman Richard Eyre.
“Current trading reassures the board that the outlook for Next 15 continues to be positive.”
He said Next has made a good start to the new financial year with encouraging signs across its brands.
