Major Work Package for European Customer

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 major work package (the "Work Package") with its important European electronics customer (the "Customer"). This follows on from the previous four work packages for the Customer that were successfully delivered over the last two years.

The Work Package commenced on 1 May 2022 and is for one year. The contract delivers a monthly revenue run rate equivalent to that delivered in H1 FY22 and further underpins our cash runway to H1 CY23. Additionally, the working capital arrangements in the contract support Nanoco establishing a more robust supply chain of raw materials. As a result, the Board now expects to exceed its recently increased revenue expectations for FY22.

Brian Tenner, Nanoco's CEO, commented:

"This is a very important step for Nanoco. It creates a significantly more stable financial environment for operations and business planning compared to the previous series of short, quarterly, work packages. The addition of new materials to the development pipeline emphasises the long-term nature of our relationship with our customer.

"Furthermore, the support for working capital will enhance our readiness for visibility of potential commercial production orders in the second half of CY22. Any production orders received will be in addition to this work package. We continue our efforts to consolidate our R&D and scale up activities in our Runcorn production facility ahead of final product validation and potential commercial orders.

"While we take nothing for granted with regard to commercial orders, we remain focused on our short to medium term goal of commercialising Nanoco's nanomaterials with meaningful production volumes, subject to final customer adoption of the technology in end use devices."

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.
