UK Circuits Secures New Manufacturing Partnership and Production Capacity Expansion

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, is pleased to announce that its Contract Electronics Manufacturing division, UK Circuits and Electronics Solutions Limited ("UK Circuits"), has entered into a manufacturing partnership with a leading provider of workforce management and access control solutions serving the construction and infrastructure sectors (the "Partner").

As part of the partnership, UK Circuits has purchased a Surface Mount Technology ("SMT") production line previously utilised by the Partner, with installation and commissioning recently completed at the Company's Oldham manufacturing facility.

The new SMT equipment represents a significant enhancement to one of UK Circuits' three manufacturing lines, increasing component placement throughput by approximately 40-50% whilst also providing improved placement accuracy, greater feeder capacity and access to an upgraded software platform with enhanced functionality.

An initial manufacturing order of approximately £70,000 has already been received from the Partner for the current financial year. In addition, the Partner has indicated the potential for total orders of up to £200,000, also for the current financial year, subject to the value of transitional levels of free issue components that UK Circuits will be required to utilise to clear the Partner's remaining stocks.

The project comprises the manufacture of four printed circuit board assemblies ("PCBAs") for industrial control systems relating to fire safety.

About the Partner:

The Partner is a leading provider of workforce management, access control and safety solutions for the construction and infrastructure sectors. The business forms part of a global group that is one of the world's largest providers of intelligent access and security solutions, with operations in more than 70 countries worldwide and annual revenues exceeding £12 billion.

Simon Deacon, Chief Executive Officer of Light Science Technologies, commented: "The transfer and installation of this SMT production line represents a significant enhancement to our manufacturing capability and demonstrates the strength of our new relationship with a leading provider of workforce management and access control solutions.

"The increased capacity, improved efficiency and enhanced technical capability will support both existing customer programmes and future growth opportunities. We are also delighted to secure this initial order and look forward to developing the relationship further."

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

Light Science Technologies Holdings plc ("LSTH") operates through three divisions: Passive fire protection ("PFP"); AgTech ("AGT") and contract electronics manufacturing ("CEM"). 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 food security, climate change, and fire protection, 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.
