Powerhouse (AIM:PHE), a company pioneering integrated technology that converts non-recyclable waste into low carbon energy together with a revenue generating engineering consulting division (Engsolve), is pleased to announce a trading update for its wholly owned subsidiary, Engsolve.

Further to the update provided in May 2025, Engsolve has progressed all those contracts as noted below as well as gained new contracts. The contracts gained are made up of both new and returning clients encompassing work from Front End Engineering Design ("FEED"), Owners Engineer Support, process safety and design, as well as design and build of lab scale and pilot facilities for new technology providers.

The largest of these contracts include:

• FEED for National Hydrogen was completed, as announced in June 2025.
• Owners Engineer Support for Wastefuel of America on a large-scale Bio-Methanol facility was completed in September 2025.
• Design and build of a first of a kind Aluminium Recycling process, design has been completed, and the build is in progress with completion planned before the end of 2025.

• Safety Engineering study including HAZOP for onshore oil production facility.
• Design of novel mobile renewable water from air generation unit.

All the contracts above are in addition to ongoing projects, whilst also supporting PHE. Engsolve also has several contracts still in negotiation that the Board believes should lead to a strong start to 2026.

These contracts, as well as the strong pipeline that is expected to be seen over the coming year, now necessitates growing the Engsolve team further. Engsolve has recruited throughout the year and expects to add additional staff in early 2026.

Paul Emmitt, Chief Executive Officer of Powerhouse, commented:

"This has been a fantastic year for Engsolve and again proves that there is a substantial opportunity to grow the business, as a standalone business as well as a subsidiary of PHE. The continued growth is testament to the teams' hard work and professionalism, as well as the growing reputation and expertise of Engsolve - which is also shown by the amount of returning clients that the company has.

"It is also very encouraging that Engsolve is providing its expertise across a range of new sectors and technologies and will look to build on this offering to industry further as the company grows.

"We look forward to continuing to grow the business and providing what we expect to be a strong start to 2026."
