Zenith and Rentokil Contracts Update

Light Science Technologies Holdings plc (AIM: LST), the controlled environment agriculture ("CEA") technology and contract electronics manufacturing ("CEM") group, announces the start of its contract with Zenith Nurseries Ltd ("Zenith Nurseries") with a total potential value of up to £13.84 million*.

·    Commencement of contract potentially worth up to £13.84 million*

·    New cloche product to extend routes to market

·    New orders from existing client in CEM division underpinning strong forward order book

As disclosed in the Company's Admission Document, the project involves a consortium (Light Science Technologies Ltd, Zenith Nurseries and Morrish Engineering Limited) developing a cloche lighting and sensor technology system.

This innovative product seeks to bring lighting and sensor technology to the controlled environment technology market for growers in polytunnel and glasshouse environments. Furthermore, the solution is intended to extend the use of the Company's nurturGROW Sensor to new market applications, such as agriculture fields. The cloche lighting and sensor technology system is expected to be the first retrofittable, all-in-one lighting-sensing-automation rig providing year-round harvests for the grower across multiple plant varieties.

With an initial potential UK market of 4,000 industrial growers, producing over 300 types of field-scale and protected vegetable and salad crops, and tree and berry fruits, the solution will aim to improve productivity by increasing yields. It will look to help growers by providing a possible solution to labour shortages and reduce the need for import substitution by extending the harvest window.

* subject, inter alia, to certain milestones and conditions as more fully described in the Company's announcement on 15 October 2021 .
