Inspired PLC (AIM:INSE) said demand from businesses for energy and ESG advice lifted revenues by 10% in its latest half year.
Interim revenues rose to £44.6 million (£40.4m), helped by ESG services rising by 98% to £2.4m, while energy optimisation, the largest division, was up 14% at £22.4m.
Underlying profits (adjusted EBITDA) rose 9% to £10.6m, though earn-out payments and a raft of one-off charges meant pre-tax profits dropped to £0.19m from £2.4m.
Mark Dickinson, chief executive, said: "We are pleased to have delivered solid financial and operational progress during the first half.
“We have been delighted by the momentum achieved in the Optimisation and ESG divisions in particular, as these offerings become ever more relevant to our customers in the current climate.
"Whilst the economic backdrop continues to present risks, our solid first-half performance, strong market position and unique ability to support customers across a wide offering, provide us with confidence for the second half and beyond."
Net debt rose to £49.1m (£42.9m), while the interim dividend rises 8% to 1.4p.
