About Nanoco Group plc

Nanoco (LSE: NANO) is a world leader in the development and manufacture of cadmium-free quantum dots and other specific nanomaterials emanating from its technology platform. In particular, Nanoco is a nanomaterial production and licensing group, specialising in the production of its patented cadmium free quantum dots (CFQD® materials) and other patented nanomaterials 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 its existing scaled up production facilities for commercial orders.

Nanomaterials are materials with dimensions typically in the range 1 - 100 nm. Nanomaterials have a range of useful properties, including optical and electronic. Quantum dots are a subclass of nanomaterial 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 spectra, rendering them useful for applications including cameras and image sensors.

Nanoco is listed on the Main Market of the London Stock Exchange, holds the LSE's Green Economy Mark, and trades under the ticker symbol NANO. For further information please visit: www.nanocotechnologies.com
