("Nanoco", the "Group", or the "Company")

Joint Development Agreement ("JDA") with the European Customer

Nanoco Group plc (LSE: NANO), a world leader in the development and manufacture of cadmium-free quantum dots and other nanomaterials emanating from its technology platform, today announces that it has signed a Statement of Work with significant joint development activities (the "JDA") with STMicroelectronics, an important European electronics customer ("ST").

The JDA is a two year programme to optimise the performance of a second generation sensing material to be developed by Nanoco. The new JDA will include revenue for services that Nanoco will soon be able to offer in the extended Runcorn facility, particularly in device testing and analytical services.

If all of the technical milestones in the two years of the JDA are achieved, the next step in the process will be to scale the new material into an industrialised process capable of supporting high volume applications.

The JDA helps to underpin the Board's expectations for non-license fee income in FY24, which are in line with FY23. The JDA is also expected to deliver additional sales of test materials during FY24 and FY25.

Brian Tenner, Nanoco's CEO, commented:

"The Group's significantly improved financial position allows us to proactively invest to accelerate development of new materials and new service capabilities. The new 200mm wafer device capability is one such example. This expanded range of services has created a compelling offering for ST who will be the first to take advantage of these new capabilities in the future.

"Further production orders received for first generation sensing materials will be in parallel with this JDA. ST's commitment to developing a second generation material, emphasises Nanoco's ability to be a robust partner in complex electronics supply chains."

About Nanoco Group plc

Nanoco (LSE: NANO) is a nano-material production company, specialising in the production of its patented cadmium free quantum dots (CFQD®) and other patented nano-materials for use in the electronics industries.

Founded in 2001 and headquartered in Runcorn, UK, Nanoco continues to build out a world-class, patent-protected IP portfolio alongside the scaling of the production for commercial orders.

Nano-materials are materials with dimensions typically in the range 1 - 100 nm. Nano-materials have a range of useful properties, including optical and electronic. Quantum dots are a subclass of nano-material that have size-dependent optical and electronic properties. Within the sphere of quantum dots, the Group exploits different characteristics of the quantum dots to target different performance criteria that are attractive to specific markets or end-user applications such as the Sensor, Electronics and Display markets. Nanoco's CFQD® quantum dots are free of cadmium and other toxic heavy metals, and can be tuned to emit light at different wavelengths across the visible and infrared spectrum, rendering them useful for a wide range of display applications. Nanoco's HEATWAVE™ quantum dots can be tuned to absorb light at different wavelengths across the near-infrared spectrum, rendering them useful for applications including cameras and image sensors.

Nanoco is listed on the Main Market of the London Stock Exchange and trades under the ticker symbol NANO. For further information please visit: www.nanocotechnologies.com.
