Hercules added to Balfour Beatty's Power Transmission and Distribution Division's Preferred Supplier List

Hercules plc (AIM: HERC), a leading technology enabled labour supply company for the UK infrastructure and construction sectors, is pleased to announce that it has secured a place on Balfour Beatty's Preferred Supplier List ("PSL") for its Power Transmission & Distribution work.

Being added to the PSL strengthens Hercules' longstanding relationship with Balfour Beatty, which is developing some of the UK's most ambitious power transmission and distribution projects. Hercules will provide specialist substation, cable and civils labour support.  

Hercules' expansion in the power and energy sector began with the Company's largest acquisition to date, Advantage NRG Ltd ("Advantage NRG") in June 2025. Advantage NRG supplies linesmen for the construction and maintenance of overhead electrical transmission lines. Hercules increased its presence in the sector in October 2025 with the acquisition of a 70% interest in Warrington-based Lyons Power Services Ltd, a specialist UK and overseas provider of power and energy infrastructure services, as well as commissioning engineers to the transmission and distribution network.

Brusk Korkmaz, CEO of Hercules plc, said: "Being added to Balfour Beatty's Preferred Supplier List for its Power Transmission and Distribution work is another milestone in Hercules' expansion in the UK energy infrastructure market. It reflects our strong working relationship with Balfour Beatty and the capabilities we have built in specialist labour supply across substations, cabling and civils.

"This development supports Hercules' continued expansion in the power and energy sector and provides an opportunity to deploy the expertise of our recent acquisition, Advantage NRG. We see significant investment continuing across the UK energy infrastructure sector as it responds to rising demand and long-term network requirements over the next decade."
