Continued Travelan® H1 sales growth (+11% on pcp) in Australia can be contributed to: (1) increased awareness and consideration driven by extensive digital and social media marketing. (2) same store growth as a result of increased promotion and past promotions driving new customers and return customers respectively; (3) growth from new stores within banner groups in which we secured core ranging in FY25; (4) increased South East Asian travel. These growth factors were offset by a one-off reduction of stock holding by the merged Sigma Healthcare/Chemist Warehouse group. Although it is difficult launching close to year end, we managed to launch ProIBS® (https://investors.immuron.com.au/announcements/7225649) prior to Christmas ahead of schedule to gain some early opportunities. ProIBS® is stocked by two of the three largest pharmacy wholesalers with listings in five banner groups. 2026 category reviews provides us with the opportunity for additional listings. We believe that once Australian consumers try ProIBS®, they will love it! H1 sales in the U.S. increased (+17% on pcp) on the back on number of marketing initiatives including: (1) improved Travelan® store on Amazon.com; (2) local U.S. Travelan® Facebook and Instagram pages; (3) increased paid social, influencer and organic social media marketing. During FY25 we had a Q1 pipeline fill into over a thousand Canada retail doors on the back of securing listings within key pharmacy and grocery retail groups. As expected, sales picked up on the back of consumer promotions in Q2 FY26 (+191% on prior quarter). We anticipate a continued increase in pull through from stores as we continue to build Travelan® brand awareness within Canada though our in- store educational programs, in-store promotions, and social media marketing. Travelan® will be launched into Jean Coutu pharmacies in 3QFY26. Jean Coutu is the number one or two pharmacy group in Quebec, the second largest province in Canada by population.
