Executive summary
Interim results for the six months ending 30 September 2025 show a NAV per share of 90.1p, reflecting a 12% decrease driven by lower revenue curves in key markets.
Operational capacity reached 643.1 MW with 94%+ availability, as all construction assets were energized and US assets (Texas and California) brought online.
Portfolio is highly diversified across GB, Ireland, California, Texas, and Germany, totaling 1.16 GW.
Board refresh and succession advanced, with new chair and directors appointed following shareholder engagement and an activist challenge.
Comprehensive strategy review led to asset monetisation plans, cost reductions, and a revised capital allocation strategy focused on asset sales, augmentations, and revenue optimisation.
Financial highlights
NAV per share declined from 102.8p to 90.1p, the largest single-period drop since IPO, mainly due to revised revenue assumptions and fund expenses.
Total revenue for the period was £16.74m, with operational EBITDA of £8.6m (51% margin).
Annualised dividend yield was 8.5%, with 2.19p per share declared for the period, including a special dividend.
Gearing stood at 18.3% of gross asset value, with £101.95m in debt drawn.
Group cash of £50.5m and undrawn debt capacity of £41.7m support reinvestment and growth.
Outlook and guidance
Management expects continued pressure on merchant revenues due to increased storage buildout, especially in Texas and California.
Contracted revenue expected to comprise over 25% of CY2026 revenue, reducing merchant risk.
Augmentation of key GB and Irish assets to two-hour duration is underway, with Stony and Ferrymuir upgrades scheduled for FY2026 Q3.
Middleton project in GB progressing through the LDES scheme, targeting 800 MWh capacity and 20 years of revenue certainty.
Focus remains on cost reduction, revenue optimization, capital recycling, and prudent leverage management.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
