("Plant Health Care" or the "Company")

 Commercial-Scale Manufacturing for Saori^® Soybean Seed Treatment

Plant Health Care^® (AIM: PHC.L) a leading provider of novel patent-protected biological products to global agriculture markets, is pleased to provide the following update in relation to the volume manufacture of its Saori soybean seed treatment, recently launched in Brazil with Nutrien Ag Solutions.

Highlights

-  Signed a production and supply agreement with a leading European-based fermentation company, securing production capacity of PHC279, the active ingredient in its Saori soybean seed treatment, to meet projected global demand.

-  Volume production cost targets have been met, ensuring an attractive gross margin for the Company and an attractive Return on Investment (ROI) for soybean farmers in Brazil.

-  Commencing pilot-scale manufacturing of other PREtec peptides within the same facility in support of new product regulatory filings and, ultimately, commercial-scale manufacturing of a portfolio of PREtec-based products.

Overview

Saori, which is proven to make soy plants healthier, improve resistance to disease and increases yield in an environmentally sustainable way, is the Company's first product from its PREtec platform to be commercialised and is the first PREtec peptide approved in Brazil.

PREtec peptides represent a novel class of technology which stimulate the plant to defend itself. Derived from natural proteins, PREtec is an environmentally friendly approach to protecting crops and is compatible with mainstream agricultural practices.

The Company intends to commercialise Saori and other PREtec peptides in markets worth more than $5 billion.

The launch of PHC279 in the USA will follow, once regulatory licences have been obtained, which is anticipated in the second half of 2022.

Chris Richards, CEO of Plant Health Care said, "We are delighted to have achieved this critical milestone in bringing our exciting new technology to market around the world.  This new agreement establishes a first-class capability to supply Saori directly to our distribution partner in Brazil.  Initial grower response to the launch of the Saori soybean seed treatment with Nutrien Ag Solutions in Brazil has been most encouraging and we are pleased to have established manufacturing arrangements to support wider adoption of PHC279 in 2022 and beyond."
