The target was unveiled as Waterman reported a jump in pre-tax profit for the six months to December 31 2015 to £1.8m from £1.1m on revenue up to £45.4m from £41.4m.
Staff numbers also increased 5% during the period rising to 1,317.
The company said: ‘The results have benefitted from the Board’s strategy of focusing primarily on the UK, where 90% of Waterman’s revenue is now generated and this focus is anticipated to continue for the foreseeable future.
“Waterman’s long-standing relationships with blue chip companies continue to generate repeat business year on year and the Board expects this to continue whilst the UK economy is strong.”
Nick Taylor, Chief Executive said: “The Board’s aspiration is to increase the Group’s adjusted operating profit margin towards 6.0% by June 2019.
“Compared with last year we have delivered a 24% improvement from 3.3% to 4.1%.”
