£0.8m of Further PFP Business Secured

Continued commercial momentum across materials supply and installation

Light Science Technologies Holdings plc (AIM: LST), the innovative technology and manufacturing business providing real-world solutions targeting issues including fire safety and global food security, is pleased to announce that its Passive Fire Protection ("PFP") division has secured approximately £0.8 million of additional business since the Company's PFP Division trading update released on 24 June 2026.

The additional business comprises further orders and invoiced sales of the Group's Injectaclad cavity fire barrier system through its installer network and two further contracts secured by the Company's in-house installation business, Injecta Fire Barrier.

The two new installation projects are located in Birmingham and Leicester, with the Leicester project having recently been approved by the Building Safety Regulator. Together, these two new projects add to the installations in Hull and Liverpool, as referenced in the Company's announcement on 24 June 2026.

The PFP division is now supplying or undertaking works across a broad range of buildings, including high-rise residential properties, hotels, schools and social housing, at locations across the UK.

The continued commercial progress follows the Company's PFP market update of 27 August 2026, which highlighted developments within the UK fire safety and building remediation market and the significant opportunity this represents for the Group.

Simon Deacon, CEO of Light Science Technologies Holdings plc, commented: "Securing approximately £0.8 million of further business since our June update demonstrates the continued commercial momentum within our PFP division. We are seeing progress across both parts of our strategy, with increasing Injectaclad sales through our installer network alongside further projects secured by our own installation team.

"We are particularly encouraged by the growing number and range of projects on which Injectaclad is now being deployed, giving us further confidence in the opportunity ahead."
