Contract Wins

Light Science Technologies Holdings plc (AIM: LST), the innovative technology and manufacturing business providing real-world solutions targeting issues including global food security and fire safety, announces that it has signed two contracts with two new clients in its Passive Fire Protection ("PFP") division, which together are worth c.£0.45m.

The contracts relate to two projects, in Manchester and Birmingham respectively, and address the remediation of a hotel operated by a prominent multinational chain, and a school building for a leading UK construction company. Importantly, there is significant potential to increase the scope of both of the relationships with a large number of additional buildings within the respective new clients' portfolios.

The contracts, which will be completed in H2 2025, further demonstrate the scale of the legislation-backed opportunity - with the Company providing a cost-effective and minimally disruptive solution. This requirement is immediate, substantive and growing, and Government has been particularly vocal about its commitment to clearing the remediation backlog. The Company continues to benefit from growing demand from both existing and new customers.

Reforms to Building Safety Regulation to accelerate house building and remediation

The recent creation of an arm's length body under the Ministry of Housing, Communities and Local Government, taking on functions of the Building Safety Regulator, is expected to result in a fast-track process for new builds and remediation. Once implemented, the Board believes that there will be further opportunities to scale operations.

The Company is in active talks with a number of potential and existing customers, and the Board is confident of securing new contracts in the near-term. Importantly, it is seeing growing demand for larger projects, which is expected to further increase the contribution from the PFP division.

Simon Deacon, CEO of LSTH commented: "We are delighted by the improving momentum in the PFP division, seeing further conversion of the c.£24 million quoted pipeline. Despite broader market issues causing some contract delays, specifically the long timescales taken by the Building Safety Regulator to sign off fire safety in tall buildings, and the UK Government responding by making structural changes to the regulator itself, we are now seeing this bottleneck starting to unblock and are confident that pipeline conversion will rapidly grow. Encouragingly, we are already seeing initial follow-on activity with one customer.

This is a legislation-backed opportunity and our solution is already proven, with a growing number of existing and new clients wanting to rectify non-compliant public and private buildings, spanning residential, commercial, and industrial sectors."

Passive Fire Protection (https://injectafirebarrier.com/)

LSTH IFB offers a practical and cost-effective solution to rectify non-compliant public and private buildings, spanning residential, commercial, and industrial sectors, with regard to fire safety regulations - a challenge addressed by a £6.1 billion allocation from the UK government. Serving as the UK's premier independent approved installer, LSTH IFB utilises the ground-breaking Injectaclad fire-resistant graphite barrier system. This system is retroactively installed within building cavities, reinstating fire-resistant performance and containing the spread of fire and smoke compliant with regulatory requirements. This innovative solution stands out as an appealing alternative to the more costly and disruptive method of removing external facades and installing traditional fire barriers. With a proven track record in the passive fire protection market and a robust sales pipeline, LSTH IFB targets a UK market potentially valued at up to £50 billion*.
