Ampeak Energy (LSE:AMP) has packed a lot into the past few months: a sale of part of its flagship battery storage project, a new non-executive director, a planned change of chief executive and a run of share purchases by its chairman.

Interim results

Results for the six months to 30 June 2026 were published on 23 September 2026. Revenue was £2.2m, down from £3.5m, mainly because of reduced electricity generation from the MeyGen tidal project while turbines were serviced. Operating costs were lower at £3.7m, and the loss before tax was £4.7m, broadly in line with the prior period. Cash at 30 June 2026 was £3.6m.

After the period end, Ampeak sold a 24.7% ownership interest in AW1 Storage Holdings Limited for £7.8m, which the company said strengthened its liquidity. The chairman's statement described 2025 as the most significant year in the company's history, as it moved from project developer towards operator.

The AW1 investment

The sale ties in with an announcement on 31 August 2026, when LSE:AMP said JBR Energy Holdings, a vehicle owned by directors of civil engineering contractor Jones Bros Ruthin, had invested in the AW1 project. AW1, short for Afon Wysg 1, is a battery energy storage project.

What Ampeak does

Ampeak develops, owns and operates sustainable power projects, with segments that include battery storage and tidal stream generation. The company rebranded as Ampeak Energy in September 2025. Its tidal interest in MeyGen sits alongside a growing pipeline of battery projects.

Leadership and board changes

On 23 September 2026 LSE:AMP announced that chief executive Graham Reid will retire on 4 January 2027, remaining on the board as a non-executive director for continuity. He will be succeeded by David Taaffe, the current chief operating officer, who has been with the company since 2011 and chief operating officer since June 2022. Peter Parry was appointed a non-executive director on 7 September 2026. At the annual meeting on 14 July 2026, shareholders also voted on proposed board appointments.

Chairman Duncan Black bought 750,000 shares at 1.9p each on 1 October 2026, and further director dealings were notified on 28 September, 2 October and 6 October. An application for a block listing was also made on 18 September 2026.

Sector and index context

Ampeak (LSE:AMP) is a constituent of the FTSE AIM All Share Index. Battery storage has become a favoured segment of the UK energy transition because it helps balance a grid with growing wind and solar output. Selling stakes in projects to partners and investors is a common way for developers to raise cash without issuing shares at low valuations.

Key risks

Revenue is small and exposed to the availability of the MeyGen turbines, as the fall from £3.5m to £2.2m shows. The company reported a loss of £4.7m for the half and had £3.6m of cash before the £7.8m sale proceeds. Construction, grid connection and financing risks apply to battery projects, and a Leadership transition adds execution risk. Shares trading at under two pence can also move sharply on modest volumes.

What to watch next

Investors will look for completion and receipt of the AW1 proceeds, progress on construction and commissioning, an update on MeyGen output after servicing, and Mr Taaffe's strategy once he takes over in January 2027. Further director purchases may also be reported, following the notification of a major holding on 5 October 2026, and the market will want to see how the strengthened Balance Sheet is used to fund the next phase of battery development.
