Melton-based Allam Marine has reported a £20m increase in turnover.
Its latest results show turnover in 2013 was £120m, compared to £100m the previous year.
The generator supplier, which is run by the Hull City chairman Assem Allam and his son Ehab, put its sales increase down to improving conditions in the Middle East and renewed faith in the Euro.
It blamed a 2.1 per cent drop in gross profit margins, to 11.8 per cent, on adverse exchange rates.
Profits increased to £11.3m, however, up from 10.4m in 2012.
Allam Marine had net assets of £44.5m on December 31, 2013. It saw a huge rise in turnover from the European market beyond the UK, rising £18m to £23m last year.
Turnover in markets outside the EU fell by just over £1m to £80m.
The company employs over 40 people and has its headquarters in Melton.
