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

Business Update, Notice of Results & Investor Presentation

Light Science Technologies Holdings plc (AIM: LST), comprising three divisions: controlled environment agriculture ("CEA"); contract electronics manufacturing ("CEM") and passive fire protection ("PFP"), is pleased to provide the following business update and notice of results (for the 12 months to 30 November 2023).

Contract Electronics Manufacturing

Susan Johnson has been appointed Business Development Manager in the CEM division for UK Circuits. Susan brings substantial experience in the electronics industry and will lead business development, focusing on new growing markets sectors, bringing new clients to the business, and servicing the existing customer base.

Additionally, the first 100 units of UK Circuits' initial order for the sports entertainment market segment, announced 8 February 2024, have now been delivered; delivery of the remaining 4,900 units is expected in Q2 2024. The Board believes that this venture holds significant potential for follow on revenue in this new segment.

The CEM division's current forward order book remains strong at over £4 million, putting it on track when combined with orders already invoiced, to meet internal sales expectations for H1 2024, and setting a solid foundation for the second half of the year.

Controlled Environment Agriculture

The CEA division continues its strategy of integrating the products and technologies of Tomtech and Light Science Technologies. Experienced industry professional, Jonathan Barton, is leading the sale of products in the UK. Globally, the division is continuing its work on setting up distributor agreements.

The pipeline of quoted business currently stands at nearly £40 million in this division.

Passive Fire Protection

The PFP division continues to roll out its project in Manchester and to develop its strong pipeline of quoted work, now valued over £9 million, in a UK market potentially worth up to £50 billion*. The Group's current contract being implemented in Manchester is worth over £600,000 and is the first since LSTH's acquisition of Injecta Fire Barrier trade and assets ("IFB").

Simon Deacon, Chief Executive Officer of LSTH, commented: "We are pleased to see the continuation of the strong momentum that has been building in the Group. I'm proud to note the initial delivery of units in our first ever sale to the sports entertainment market in the CEM division, which I believe is a strong indicator of the versatility that UKC boasts as we focus on increasing margin and opening up new markets.

"As a Board, we are extremely excited by the prospects of our CEA division after the acquisition of Tomtech last year, and as the world begins to recognise and adapt to the challenges that threaten growing practices and food security in the years to come.

"We believe we will see more growth in the market as food security around the world is taken more seriously - driven particularly through extreme weather pattens and a desire for healthier food production."

Controlled Environment Agriculture

The Group's tailored 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 medicinal 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 Americas, Australasia, and select locations in the Middle East.

The sensorGROW technology enables real-time monitoring of essential air zone growing factors such as carbon dioxide, air humidity, air pressure, air temperature, and light. In development, it aims to extend monitoring to soil temperature, soil moisture, and soil electroconductivity. This empowers farmers to enhance resource management, saving costs on water, nutrients, fertilizers, and energy, while simultaneously increasing yields and cultivating healthier crops.

UK Circuits serves as the Group's profitable and revenue-strong CEM-focused division. It excels in designing, procuring, and manufacturing high-quality CEM products, with a specialization in Printed Circuit Boards. These products find application across diverse sectors such as audio, automotive, electronics, gas detection, lighting, pest control, telecommunications, and, more recently, in the CEA market.

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 £5.1 billion allocation from the UK government. Serving as the UK's premier independent approved installer, LSTH IFB utilizes 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.
