Listed independent technology group Cohort plc has posted a solid first half, with revenue up 9% to £128.8 million, helped by growth across most of its businesses.

Adjusted operating profit dipped slightly to £9.7m and margins eased to 7.5%, largely due to a mix shift in Sensors and Effectors and planned lower-margin deliveries on a major Italian sonar programme.

Management kept full-year expectations unchanged and lifted the interim dividend 10% to 5.8p.
