SDCL Efficiency Income Trust plc("SEIT" or the "Company")

Operational Update Statement

The Company announces an Operational Update Statement for the six months from 1 April 2025 to 30 September 2025 (the "Period").

Jonathan Maxwell, CEO of the Investment Manager, SDCL, said:

"SEIT's portfolio continues to deliver operational performance that is broadly in line with expectations, despite having limited access to growth capital from SEIT itself.

"We are actively progressing disposals as a priority and reported a small successful disposal during the Period, which completed at a significant premium to NAV. It is intended that proceeds of additional disposals will be used to reduce SEIT's drawings under its revolving credit facilities and, in due course, to return capital to shareholders through share buybacks or a tender offer."

Operational Update

During the six months to 30 June 2025, SEIT's portfolio has delivered operational performance in line with budget on an aggregated basis. Key highlights include:

Primary Energy: We were pleased to see an improved customer credit rating following the Nippon Steel acquisition of US Steel. There has been continued strong performance across all five projects. North Lake, one of the projects, also received approval from the Ohio RPS program to increase certified capacity certification, that will generate significant additional revenue at no extra capital cost. The Contract at PCI was successfully renewed, for a further five years, with a two-year extension option.

RED-Rochester: The Cogen project concluded successfully and is already delivering efficiency benefits. Performance was supported by a particularly strong first quarter due to higher loads related to colder-than-expected weather.

Driva: Strong performance from a combination of sales from core business and new Energy-as-a-Service projects delivered EBITDA above budget. Operational metrics continue to improve, with increased biogas injection, and reduced leakage.

Onyx: Year-to-date performance of the operational portfolios was below budget due to site-specific challenges, including higher panel soiling and snow losses. While a partial recovery is expected, full-year EBITDA of the operational portfolios is projected to fall slightly short of budget. Deployment remains robust, supported by the commercial attractiveness of its decentralised energy offering.

Oliva: Volatility in gas and electricity markets has put pressure on financial performance, however changes to the management team's hedging methodology have had a positive impact. Additionally, the team is progressing a strategic plan to assess potential new project opportunities.

Disposals

During the Period, the Company successfully completed the $7.6m disposal of ON Energy at an 18.75% premium to the latest holding value.

The Manager continues to progress other disposal processes to create liquidity and streamline the portfolio and will update shareholders as these processes reach fruition.

Results

The Company expects to report its interim results for the Period to 30 September 2025 in early December and will provide further details in due course.
