Company update

Research & Development Tax Credit

The Company is also pleased to announce it has now received a research and development tax credit from HMRC in the amount of £262,000 for qualifying costs expended in 2022. These costs primarily relate to research and development work by the Company on the pathogen detector for identifying Covid-19 in water. As previously announced, the Company is further developing a device to identify and monitor a wide range of pathogens in water, by adapting the Covid-19 model into an online multi-pathogen detector capable of delivering rapid results.

Business Restructuring

Having restructured the business at the turn of the year, the Board remains committed to the Company's reset objectives starting this year and to applying a business plan built on the integration of the Microsaic Systems and Modern Water technologies. This technical integration for water testing services is now branded and marketed as 'Tethys Purity' to reflect the broad and comprehensive water testing capabilities that the Company can now offer. Tethys Purity is a modular concept where customers can select the entire suite or a range of devices and services to meet their specific needs, from PFAS detection to toxic water monitoring including pathogen identification. The Company is actively building up partnerships and joint ventures to support its commercial objectives to deliver a total solution for water testing and safety.

Bob Moore, Acting Executive Chairman of Microsaic, commented:

"We are moving the Company forward by building on our newly combined technologies and enhanced business capabilities. We look forward to completing our worthwhile projects as part of our wider objective of growth and business development, and to building mutually rewarding partnerships to create value for our investors."
