Quantum Dot Material Supply Agreement

Agreement with STMicroelectronics further underpins cash runway to 2021

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 signed a Quantum Dot Material Supply Agreement ('QDMSA' or 'Agreement') with STMicroelectronics International NV ('ST').

The QDMSA is a framework agreement that covers both development work and commercial supply of nano-materials for use in various infra-red sensing applications over an initial five-year period. The Agreement extends the collaboration that was in place while both companies were working for our mutual significant US Customer.

Orders for development work on material for a new application and small scale volumes of an existing material have already been received. The first phase of the development work which started in April is scheduled to last until December 2020.

The new purchase orders are material in size for Nanoco and underpin the extended operational cash runway to Q2 2021, as recently announced in our Interim Results on 30 April 2020. Any further purchase orders will improve that position. The QDMSA also commits ST to certain minimum volumes in the event that future commercial production orders are required.

Dr Michael Edelman, Nanoco's CEO, commented:

"We are very pleased with this latest development in our collaboration with ST. Both companies have been working actively to generate value from our previous two years of investments in developing new materials, devices, and mass production capabilities for use in infra-red sensing. The Agreement now enables us find new routes to market in the short term, and potential new applications in the medium term.

"ST's deep knowledge of the sensing markets and multiple potential applications and customers makes them an ideal strategic customer for Nanoco. Nanoco's materials deliver a very significant performance enhancement to ST's silicon based infra-red sensors. A medium term roadmap to commercial production volumes, enabled by our newly developed materials, is taking shape. This will allow us to leverage the value from our recent investment in our new Runcorn electronics materials production facility."

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. 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 and Electronics markets. One of the interesting properties 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.
