THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION FOR THE PURPOSES OF ARTICLE 7 OF THE MARKET ABUSE REGULATION (596/2014/EU) AS THE SAME HAS BEEN RETAINED IN UK LAW AS AMENDED BY THE MARKET ABUSE (AMENDMENT) (EU EXIT) REGULATIONS (SI 2019/310) ("UK MAR").

Litigation Update - Funded Law Suit Filed in China

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 that it has filed a law suit against Samsung in China for the willful infringement of the Group's IP.

This third law suit against Samsung is based on a sister patent to one of the patents in the US litigation. China is a significant market for the sale of high-end televisions, and is estimated to be one of Samsung's larger markets for the sale of QD TVs.

The Group is continuing its focused approach to litigation in different jurisdictions to allow more rapid and less costly outcomes to be arrived at. The Funder for the US litigation has agreed an expanded budget on similar commercial terms as the existing funding to cover the litigation in China.

The Group continues to review options for litigation either in other territories or against other parties that we believe may be infringing Nanoco's world leading and patent protected technology.

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

"Expanding our actions against Samsung reflects our confidence in the merits of our cases in the US and Germany. The litigation process in China is expected to be faster than the US process, where multiple appeals can extend for a number of years. A final outcome in China can be expected between one and two years from filing suit. China is also another territory where an injunction is more commonly available than in the US.

"We continue to pursue a patent litigation strategy that delivers fair value for Nanoco's global IP portfolio. We are grateful to be well supported in these endeavours by our Litigation Funding Partner and our legal advisers at Mintz."

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.
