Ampeak shares slide as full-year earnings fall

(Sharecast News) - Ampeak Energy shares fell more than 10% on Friday after the sustainable energy developer reported a sharp drop in EBITDA and a reduction in net assets, despite narrowing its full-year loss and delivering progress across its battery storage and tidal projects. The AIM-traded company, formerly SAE, said revenue rose to £15.0m in 2025 from £14.4m, while EBITDA fell to £3.7m from £7.9m.

Net losses narrowed to £13.9m from £25.1m, although net assets fell to £6.8m from £17.2m.

Debt excluding non-recourse debt reduced to £12.7m from £13.7m.

The share-price fall suggested investors were focused on the weaker operating earnings and reduced asset base, as Ampeak continued its transition from developer to owner and operator of sustainable energy assets.

Ampeak said 2025 was "transformational", with financial close achieved for the 240MWh AW1 battery storage project, planning permission secured for the 1,250MWh AW2 and 1,200MWh MeyBESS projects, and MeyGen generating more than 87GWh of tidal energy.

Chairman Duncan Black said Ampeak had moved "from promise to delivery; from planning to construction; from SAE to Ampeak Energy", adding that Uskmouth was on track to become one of the largest battery storage sites in the UK.

Chief executive Graham Reid said the company entered 2026 "in the strongest position" in its history, with AW1 under construction, AW2 and MeyBESS consented, and supply chain and optimisation partnerships in place.

At 1207 BST, shares in Ampeak Energy were down 10.34% at 2.6p.
