Light Science Technologies Holdings plc

("LSTH", "Light Science", the "Company" or the "Group")

New blue-chip customer contract worth in excess of £750,000 in the Passive Fire Protection Division

Appointment of Passive Fire Protection Division Managing Director

Light Science Technologies Holdings plc (AIM: LST), comprising three divisions: controlled environment agriculture ("CEA"); contract electronics manufacturing ("CEM") and passive fire protection ("PFP"), announces an initial contract with a new blue-chip customer worth in excess of £750,000, for its passive fire protection division, LSTH IFB Limited ("LSTH IFB").

The contract, with a blue-chip world leader in the construction sector, which is active in more than 120 countries, involves LSTH IFB installing the Injectaclad cavity sealant throughout an 11-storey student accommodation block in Nottingham. LSTH IFB will provide an eight-person team that will drill access holes through the structural insulated timber panels, then install Injectaclad horizontally at every floor level - per the video here. Work on the contract has now commenced and is expected to run until December 2024, with revenues being recognized in H2 of the current financial year.

Since announcing the earnings enhancing acquisition of Injecta Fire Barrier's trade and assets in November 2023, the Company has positioned LSTH IFB to take advantage of the growing fire safety retrofit market in the UK, a market estimated to be valued up to a potential of £50 billion*. In addition to the £600,000 contract won in November 2023, which is now over 50% progressed and due to be completed in H2 of the current financial year, this latest contract further demonstrates the Company's ability to convert its PFP quoted pipeline of sales opportunities, which currently stands at over £10 million.

New Divisional Managing Director

The Company is also pleased to announce that Shaun Tasker has been appointed as Managing Director of LSTH IFB. Shaun brings over 20 years of experience in commercials, sales, and operations.

Having successfully managed multimillion-pound businesses and co-managed his own facilities management company for several years, Shaun has demonstrated his expertise in running multiple enterprises. His extensive experience spans various facets of business, including project management, marketing, finance, and construction, as well as negotiating purchases and sales.

Shaun will focus on converting and growing the PFP pipeline and will work closely with the wider team with a view to further strengthening the Injecta Fire Barrier brand and operating reach.

Simon Deacon, Chief Executive Office at LSTH, commented: "Injecta Fire Barrier is a cash-generative, high-margin and scalable business and this latest contract win highlights the significant potential here. We are delighted to be working with a world leader in construction, and expect that this initial contract could lead to further work within their extensive portfolio and provide us with a case study we can take to new customers. They have an extremely strong footprint in the UK and with legislation underpinning demand for increased building safety, we believe that we are well placed to rapidly scale.

"This is LSTH IFB's second contract win since the Company's trade and assets acquisition in November 2023, further demonstrating the opportunity for us to create an operationally self-funded, cash-backed group. Management is increasingly confident of the significant growth potential and the Company's ability to add further contracts. We are in active talks with a number of prospects, and look forward to providing further updates in due course. In addition, we are delighted to welcome Shaun to the team and believe that his experience and industry contacts will further help drive growth."
