Glass Lewis recommendation to support Nanoco's Board

General Meeting - 10 August proxy voting deadline

Nanoco Group plc (LSE: NANO), a world leader in the development and manufacture of cadmium-free quantum dots and other specific nanomaterials emanating from our technology platform, notes the voting recommendations recently published by Glass Lewis & Co. ("Glass Lewis") in relation to the Group's forthcoming General Meeting to be held on 14 August 2023.

The Glass Lewis report recommends that investors vote AGAINST all resolutions that have been proposed, as follows.

· vote AGAINST all the resolutions to remove the current Board of Nanoco

· vote AGAINST the proposed appointment of all the Requisitionists' director nominees

This is in addition to the report issued by Institutional Shareholder Services ("ISS"), as announced on 2 August 2023, which recommended that investors:

· vote AGAINST all the resolutions to remove the current Board of Nanoco

· vote AGAINST the proposed appointment of the following director nominees:

o  Tariq Hamoodi

o  Greg Moeller

o  Dooyong Lee

o  Benjamin Barnett

o  Ikchoon Tim Kang

General Meeting on 14 August 2023

The Board is firmly of the view that the changes proposed by Mr Hamoodi are not in the best interests of the Company or its shareholders for the following reasons:

• Nanoco is at an exciting inflection point, with the Samsung litigation proceeds fully underpinning our transition from an R&D first mover to a leading producer of next-generation QD materials in the short term

• The Requisitionists continue to fail to present a clear, coherent and credible strategy

• Delivering shareholder value needs an experienced and qualified board - none of the Requisitionists' nominee directors have ever served on the Board of a UK public company

• The Board changes proposed by the Requisitionists in effect would represent a total change of control of Nanoco with no takeover premium being paid - a backdoor takeover attempt

• The Requisitionists' proposals will destroy the significant potential value in Nanoco's organic business, risk turning the Company into a highly speculative litigation shell, and will result in an exodus of key talent from the business, including Dr Nigel Pickett, the Group's co-founder and Chief Technology Officer

• Mr Hamoodi's unfounded allegations create a false narrative that misleads Nanoco shareholders

Shareholders have a lot to lose - the Requisitionists' resolutions are not in the best interests of shareholders

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.
