CEM Update

Healthcare client follow on-order; contract value to date now over £500,000

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, announces that its Contract Electronics Manufacturing division ("CEM"), has secured a follow-on order from the healthcare devices client it secured earlier in the year (see announcement dated 07 May 2026).

The Company has received an additional order from this customer, worth c. £342,000, with revenues expected to be recognised between November 2026 and February 2027. This is the customer’s first follow on order since LSTH won the contract, taking the order value to date to more than £500,000.

The CEM division is increasingly focusing on higher margin opportunities across a broad range of sectors including defence, medical and healthcare. To this end, the Company has recently invested c.£112,000 in Automated Optical Inspection equipment with built in AI, further enhancing the CEM division’s ability to manufacture smaller, more complex components, which are synonymous with its target markets.

Simon Deacon, CEO of LSTH commented: "I'm delighted with the continued momentum within the CEM division. Importantly we are establishing longer-term relationships with clients that have the ability to underpin repeat business opportunities, which is expected to result in increased visibility as we convert our pipeline. At the same time we are derisking this division, which is benefiting from increased capacity and improved efficiencies.

“Increasing levels of automation combined with higher level accreditations are underpinning the continued shift in revenue mix towards technically complex opportunities as we build long term relationships in higher-margin markets, positioning CEM for increasingly profitable growth.”

About Light Science Technologies Holdings plc (www.lightsciencetechnologiesholdings.com)

Light Science Technologies Holdings plc (“LSTH”) operates through three divisions: Passive fire protection ("PFP"); contract electronics manufacturing ("CEM") and AgTech (“AGT”). The Company is involved in the design, manufacturing and installation of products and customized solutions spanning various industry sectors. With a focus on addressing global challenges related to fire protection, food security and climate change, the Group is committed to developing robust solutions in these rapidly growing market sectors.

As both an installer and supplier of the fire resistant graphite barrier system Injectaclad, the PFP division is strongly positioned to capture a growing proportion of the fire remediation market as the Buildings Safety Regulator (“BSR”) backlog unblocks, enabling accelerated conversion of the Company’s strong sales pipeline. The Injectaclad system is a solution for the retrospective installation of cavity fire barriers in buildings using a pumped system, thereby avoiding the need for full-scale façade removal. It addresses a significant problem in the UK's built environment, where thousands of buildings require remediation to meet fire safety standards.

The CEM division excels in designing, procuring, and manufacturing high-quality electronic products, with a specialisation in Printed Circuit Boards. These products find application across diverse sectors such as audio, automotive, electronics, gas detection, lighting, pest control, telecommunications and AgTech.

The Group's tailored AgTech solutions encompass control systems, grow lights, sensor technology, venting, and irrigation systems, catering to both UK and global customers. Key markets include indoor, vertical, glasshouses, polytunnels, and more recently wider applications in broadacre farming. Driving factors comprise global food and water shortages, a growing population, government policies promoting sustainable growth methods, heightened scrutiny of food production's impact on climate change, and a shift away from processed foods. Key markets span the UK, Eastern Europe, the Americas, Australasia, and select locations in the Middle East, with the Company expanding routes to market via low-cost, low risk distribution agreements globally.

The Group is strongly positioned across a range of high growth sectors with proven technologies and solutions. It is increasingly focused on high margin opportunities that will drive cash generation. Furthermore, it is positioned for accelerated growth, targeting larger contracts and increasing recurring revenues - as both legislation and global issues look set to underpin demand for its products, driving the Company towards sustained profitable growth.
