NANOCO GROUP PLC

("Nanoco" or the "Company")

2022 Annual Report and Notice of Annual General Meeting (AGM)

Pursuant to Listing Rule 9.6.3, Nanoco confirms that its Notice of Annual General Meeting, Proxy voting forms and Annual Report and Accounts for the financial year ended 31 July 2022 (the "Documents") have been made available to shareholders. Shareholders opting out of electronic communication will receive paper copies of the Documents while those who have not opted out will receive a paper copy of the Proxy form only.

Copies of the Documents have also been submitted to the National Storage Mechanism and will shortly be available for inspection at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism . The Documents are also available on the Company's website at www.nanocotechnologies.com and from the Company's registered office at the Science Centre, The Heath Business and Technical Park, Runcorn, WA7 4QX.

The Directors will hold the AGM in person at their head offices, but will also facilitate a remote option for those who wish to dial in. Details are included further down. Questions should be submitted in advance of the Meeting as described in the Notice of AGM.

Shareholders will not be able to vote at the Meeting if they attend via the webinar facility. The Board therefore encourages shareholders to submit Proxy Forms and to appoint the Chairman of the Meeting as their proxy with their voting instructions.

Shareholders who hold their shares on an electronic trading platform will not receive a hard copy voting form or Proxy Form. Shareholders using such platforms should contact their service provider directly in order to vote their shares.

The Company's Annual General Meeting is being held at 11.00 am on 20 December 2022, and the following link can be used to register for those who do not wish to attend in person: https://stream.brrmedia.co.uk/broadcast/6365415893b0033e50b97bcd

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 size-tunable 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 Runcorn, 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.
