Cohort saw solid overall progress in a year of significant change and contrasts.
Revenues for the year to the end of April were virtually unchanged at £112.7m (2016: £112.6m) but adjusted operating profits rose by 22% to £14.5m and adjusted pre-tax profits were up 21% at £14.5m.
On a statutory basis, pre-tax profits fell to £1.0m from £5.3m.
Chairman Nick Prest said: "Cohort again improved its performance in the year, achieving record adjusted operating profit.
"A strong initial contribution from EID and growth at MCL offset flat performances at MASS and SEA.
"The poor performance at SCS was partly mitigated by the reorganisation at the half year with a positive contribution from the transferred operating businesses of SCS in the second half.
"Recent contract wins have given a positive start for the year and the Board considers that Cohort's order book and near-term prospects provide a good base for future progress."
