("ProBiotix" or the "Company" or, together with its subsidiary, the "Group")

New Commercial Partnership in Sweden

ProBiotix Health plc (AQSE: PBX), the life sciences business developing probiotics to support cardiometabolic health, is pleased to announce a commercial partnership with Sweden based RevivaBio.

ProBiotix has entered a commercial cooperation with RevivaBio, one of Sweden's fastest growing health companies, to launch a new cholesterol lowering product powered by the ProBiotix patented probiotic strain LP_LDL®. The collaboration marks an important step in RevivaBio's strategy, through new product introductions based on scientifically validated ingredients.

After an extensive evaluation of innovations in cardiometabolic health, RevivaBio selected LP_LDL® for its clinically validated ability to help manage cholesterol levels safely and effectively. RevivaBio's new product will be introduced and launched in Sweden and a number of APAC markets during Q1 2026, in a capsule dietary supplement under RevivaBio's own brand. The product will be distributed through health stores as well as through e-commerce activities. As part of the collaboration, ProBiotix will manufacture the primary finished capsules product and RevivaBio will be responsible for the final packaging of the product.

Founded in 2002 and headquartered in Uppsala, RevivaBio has become a recognised player in the Swedish health and nutrition market. The company develops, manufactures, and sells a wide range of science-based dietary supplements focused on gut health, histamine intolerance, inflammation, and immune balance. With its own modern production facility and a dedicated team, RevivaBio is known for its high-quality standards, innovation, and customer focus.

RevivaBio's portfolio includes well-known products such as DAOfood®, Daosin®, and Atrantil.

The company has built a strong reputation for customer satisfaction and trust, being recommended on Sweden's leading review platform, Reco.se, for seven consecutive years, with an average customer rating of 4.6 out of 5 from more than 700 verified reviews.

Cardiovascular disease remains one of the leading health challenges in Sweden and globally. RevivaBio aims to make a meaningful contribution to heart health by offering scientifically proven and natural solutions.

Steen Andersen, CEO of ProBiotix, commented: "The collaboration marks another important step in our ambition to further our expansion internationally. We are delighted to be working with RevivaBio to develop a new probiotic product, which we believe will prove a highly successful new offering.

"The cooperation further demonstrates the growing global demand for probiotic products that support heart health, and is expected to help further accelerate our sales growth."

Thomas Frid, General Manager of RevivaBio, added: "Partnering with ProBiotix Health and introducing LP_LDL® is a major milestone for us. We are proud to strengthen our product portfolio with a world-leading probiotic innovation.
