Extension of Joint Development Agreement with Asian Chemical Customer

Nanoco Group plc (LSE: NANO), a world leader in the development and manufacture of cadmium-free quantum dots and other specific nanomaterials emanating from its technology platform, is pleased to announce it has signed a three-year extension to the existing Joint Development Agreement ("JDA") with its important Asian Chemical Customer (the "customer").

The agreement continues the long collaboration between Nanoco and the Asian Chemical Customer, building on the completion of the existing two-year JDA which was originally announced on 7 November 2023. The three-year programme is to further develop the material and to scale up the manufacturing process of the Quantum Dot ("QD") nanomaterial that will be applied to silicon sensors to enable Short Wave Infrared ("SWIR") capabilities. The customer is a very significant player in electronics supply chains.

The new JDA also includes an inflationary increase to the amount the customer will pay to Nanoco compared to the previous agreement. If successful, the customer anticipates production level orders will be rolled out in 2028.

The fees received from the JDA will contribute to Nanoco's revenues in FY26, FY27, FY28 and FY29.

Dmitry Shashkov, Nanoco's CEO, commented:

"Since we started our work on Quantum Dots for sensing applications, Nanoco has proven it has the expertise and capability to not only develop the best materials but also move these through the scale up and production phases of development.

"Applying nanomaterials to silicon sensors is an affordable and scalable way to unlock short-wave infrared capabilities, and JDAs of this kind demonstrate our leadership in this area. Through Nanoco's innovative technology, we're delighted to be opening up high-volume, cost sensitive markets and applications within consumer electronics, in addition to the automotive, industrial and defence sectors.

"We continue to discuss other potential projects with multiple new potential customers and we look forward to updating shareholders further in due course."

About Nanoco Group plc

Nanoco (LSE: NANO) is a nanomaterial production and licensing group, specialising in the production of its patented cadmium free quantum dots (CFQD® materials) and other patented nanomaterials 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 its existing scaled up production facilities for commercial orders.

Nanomaterials are materials with dimensions typically in the range 1 - 100 nm. Nanomaterials have a range of useful properties, including optical and electronic. Quantum dots are a subclass of nanomaterial 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 spectra, rendering them useful for applications including cameras and image sensors.

Nanoco is listed on the Main Market of the London Stock Exchange, holds the LSE's Green Economy Mark, and trades under the ticker symbol NANO. For further information please visit: www.nanocotechnologies.com
