("Nanoco", the "Group", or the "Company")

Receipt of Final Litigation Proceeds

Proposals for Return of Capital to follow

Nanoco Group plc (LSE: NANO), a world leader in the development and manufacture of cadmium-free quantum dots and other nanomaterials emanating from its technology platform, today announces that it has received the second tranche of litigation proceeds from Samsung after settling last year on a no fault basis for the alleged infringement of the Group's IP.

The Group has received a net sum of $71.75m, being $75.0m less the expected Korean withholding tax, which amounted to $3.25m. The Korean withholding tax is available to offset Nanoco's future profits in the UK.

The Group previously announced the hedging of this tranche of proceeds at a rate of $1.22 / £1.00. The funds will be converted at this rate and generate a sterling receipt of £58.8m. This represents a gain of £2.1m compared to the current exchange rate for USD.

The Group is finalising its proposals for the amount and structure of the return of capital which can now go ahead following this receipt of the second tranche of litigation proceeds. The Group expects to update shareholders shortly on the final proposals which will be in line with the previously announced commitment to return between £33.0m and £40.0m to shareholders.

As previously communicated, the remaining proceeds will be invested in R&D and commercial activities to expand our range of high-performing materials, developing new materials with enhanced performance, as well as expanding our reach, a proactive IP licensing programme, payment of debt obligations, and to provide working capital through to the self-financing position that is expected during 2025.

Brian Tenner, Nanoco's CEO, commented:

"With receipt of these proceeds we can now finalise our plans for the significant return of capital to shareholders. The proceeds will also ensure that our commercial business is properly funded to take advantage of the growing commercial traction and development opportunities for our innovative platform technology."

The person responsible for arranging for the release of this announcement on behalf of Nanoco is Liam Gray, Company Secretary.

About Nanoco Group plc

Nanoco (LSE: NANO) is a nano-material production and licensing company, specialising in the production of its patented cadmium free quantum dots (CFQD®) and other patented nano-materials 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 the scaling of the production for commercial orders.

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. 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 spectrum, rendering them useful for applications including cameras and image sensors.
