MicroSalt secures Purchase Order with UK-based seasoning manufacturer

MicroSalt (AIM: SALT), a leading manufacturer of full-flavour natural salt with approximately 50% less sodium, is pleased to announce that it has received a Purchase Order ("PO") from a new customer, a subsidiary of a leading European group specialising in natural flavours, colours, and ingredients, with revenues exceeding €250 million and over 4,200 clients globally ("Customer").

MicroSalt has been working with this customer for the past 12 months to test products incorporating MicroSalt's technology. This initial PO is expected to be followed by further orders and whilst not significant in terms of the Group's revenue forecasts for 2026 or 2027, the contract represents the Company's first B2B commercial sale in the UK.

Rick Guiney, Chief Executive Officer of MicroSalt, commented:

"We are excited to partner with a leading player within the UK seasoning market. This relationship marks a new partner and a new vertical for MicroSalt, highlighting the continued success of our strategic business model and the strength of our innovative solutions.

"We look forward to continuing to build on the momentum we have witnessed over the last few months, establishing and nurturing further relationships with key players across the sector to drive our mission of proving lower sodium salt worldwide."

About MicroSalt

MicroSalt® is disrupting the global salt market with its patented, full-flavour, low-sodium salt designed for both food manufacturers and consumers. Using proprietary micron-sized particles, MicroSalt® delivers the same salty taste as traditional salt with approximately 50% less sodium, offering a scalable solution to one of the world's most pressing health challenges. Year to date through 2025, MicroSalt® has contributed to more than 634M servings made healthier.

Excess sodium consumption is a leading contributor to cardiovascular disease, the world's number one cause of death. The World Health Organisation has targeted a 30% reduction in global sodium intake by 2025, a shift projected to save seven million lives by 2030. The economic case is equally compelling: in the UK alone, cardiovascular disease costs £19 billion annually, and reducing average daily salt intake by just one gram could save over 4,000 lives and £288 million each year. 

Operational since 2018, MicroSalt® has established a defensible IP portfolio, holding a granted US patent and 14 pending applications worldwide. These protections create significant barriers to entry in a market expected to grow exponentially as regulation and consumer demand accelerate.

MicroSalt® is ideally positioned for scale and market leadership, with clear pathways into food manufacturing, consumer channels, and ultimately the broader £10+ billion global salt market. MicroSalt® is more than a healthier alternative - it is a disruptive, category-defining solution poised to deliver significant commercial and societal impact. From January 2025 through February 2026, there have been more than 1 billion servings of food made healthier with MicroSalt.
