Litigation Update

Texas Trial Stay Lifted - jury selection commences 12 September 2022

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, announces an update to its litigation against Samsung for the willful infringement of the Group's IP.

His Honour, Judge Gilstrap, has lifted the stay on the trial to be held in Texas. The Judge rejected Samsung's request for a further delay and ruled in favour of Nanoco to lift the stay. The pre-trial conference date has been set for 16 August 2022 and jury selection has been set for 12 September 2022. The trial is expected to follow shortly thereafter.

Brian Tenner, Chief Executive Officer of Nanoco Group plc, said:

"We were ready and confident to go to trial in September 2021. We won all 47 of our claims examined by the Patent Trial and Appeal Board in May 2022. This settled the issue of validity emphatically in Nanoco's favour. So we are ready and even more confident to go to trial in September 2022.

"The trial can now focus on the issue of Samsung's alleged wilful infringement and the appropriate level of damages. We remain convinced of the strength of our case and that a favourable trial outcome will deliver a substantial inflection point for Nanoco's prospects and shareholder value."

About Nanoco Group plc

Nanoco (LSE: NANO) harnesses the power of nano-materials. 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. The Group produces quantum dots and other nano-materials. 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 Display, Sensor and Electronics markets. An interesting property of quantum dots is their absorption spectrum. 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 image sensors. Another interesting property of quantum dots is photoluminescence: the emission of longer wavelength light upon excitation by light of a shorter wavelength. The colour of light emitted depends on the particle size. 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 applications including displays, lighting and biological imaging.

Nanoco was founded in 2001 and is headquartered in Manchester, UK, with a US subsidiary, Nanoco Inc., in Concord, MA. Nanoco continues to build out a world-class, patent-protected IP portfolio generated both by its own innovation engine, as well as through acquisition.

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.
