BALLYMENA engineering firm JBE Mechanical Electrical sustained a 15 per cent drop in revenue last year with sales falling to £16.5 million.
However, the company's profit margin in the year to April 2016 improved as pre-tax profits rising more than 20 per cent to £216,039.
The business was set up in 1983 and is now one of the north's best known electrical and mechanical contractors working across the commercial, industrial and retail sectors.
Directors said they were "satisfied with the performance of the company".
"Whilst market conditions generally remain challenging, the directors will seek every opportunity to maintain profitable trading," they added.
The firm is headquartered at Braid River Business Park in Ballymena but has an office in Scotland as well.
Among recent contract wins are several in Britain.
They include an agreement to the design, supply and install installation, lifts at Dalbeattie Learning Campus in Dumfries and Galloway, Scotland.

And last year, it was main sponsor of the Northern Ireland Football League Cup.
The firm cut back on production staff last year, meaning the overall workforce fell to 89 from 96 the previous year.
That saw the wage bill reduce to £3m (against £3.2m in 2015).
