Rhea-AI Filing Summary

Immuron Limited reports HY26 global sales revenue of A$4.2 million, up 5% on the prior year, driven by strong Travelan and ProIBS demand. Australian sales rose to A$3.3 million, up 13%, while North American revenue was A$0.9 million, down 18%, though U.S. sales within that increased 17%.

Cash was A$10.0 million at 31 December 2025, up A$7.2 million from 30 June 2025, with EBITDX (ex-R&D) of -A$1.1 million. The company is resetting its strategy by seeking partners for its clinical assets IMM-124E for traveler’s diarrhea and IMM-529 for recurrent C. difficile infection, aiming to have licensees fund further development and commercialization while Immuron focuses on over-the-counter products Travelan and ProIBS.

Insights

Immuron shows modest revenue growth, stronger cash and a lower-risk partnering strategy.

Immuron delivered HY26 revenue of A$4.2m, up 5%, with Australian sales up 13% to A$3.3m. EBITDX (ex-R&D) was still negative at -A$1.1m, but cash increased to A$10.0m, extending its operating runway.

The decision to partner IMM-124E and IMM-529 shifts future development costs to licensees. IMM-124E is eligible for an end of Phase 2 FDA meeting for traveler’s diarrhea, and IMM-529 has an approved IND to enter Phase 2 for recurrent C. difficile infection.

This model may reduce R&D cash burn and accelerate potential non-dilutive economics from upfront fees, milestones and royalties, while Immuron concentrates on OTC brands Travelan and ProIBS. Actual financial impact will depend on successfully executing partnering deals and sustaining product sales growth in Australia, North America and new channels like Jean Coutu in Canada.

About Immuron

 

Immuron Limited (ASX: IMC, NASDAQ: IMRN), is an Australian biopharmaceutical company focused on developing and commercializing orally delivered targeted polyclonal antibodies for the treatment of infectious diseases.

 

About Travelan®

 

Travelan® is an orally administered passive immunotherapy that prophylactically reduces the likelihood of contracting travelers’ diarrhea, a digestive tract disorder that is commonly caused by pathogenic bacteria and the toxins they produce. Travelan® is a highly purified tabletized preparation of hyper immune bovine antibodies and other factors, which when taken with meals bind to diarrhea-causing bacteria and prevent colonization and the pathology associated with travelers’ diarrhea. In Australia, Travelan® is a listed medicine on the Australian Register for Therapeutic Goods (AUST L 106709) and is indicated to reduce the risk of Travelers’ Diarrhea, reduce the risk of minor gastro-intestinal disorders and is antimicrobial. In Canada, Travelan® is a licensed natural health product (NPN 80046016) and is indicated to reduce the risk of Travelers’ Diarrhea. In the U.S., Travelan® is sold as a dietary supplement for digestive tract protection.

 

Travelers’ diarrhea (TD)

 

TD is generally defined as the passage of ≥ 3 unformed stools per 24 hours plus at least one additional symptom (such as nausea, vomiting, abdominal cramps, fever, blood/mucus in the stools, or fecal urgency) that develop while abroad or within 10 days of returning from any resource-limited destinations (Leung et al., 2006). Diarrhea continues to be the most frequent health problem among travelers to destinations in lower- and middle-income regions (Steffen, 2017). Deployed US military personnel, essentially representing a long-term traveller population, are particularly affected given their population dynamics and the context in which they seek care and treatment (Connor et al., 2012). Diarrhea is the leading infectious disease threat to the overall health and preparedness of deployed US armed forces, with diarrheagenic E. coli, Campylobacter spp., and Shigella spp. among the most commonly reported etiologies (Riddle et al., 2006).

 

Immuron Platform Technology

 

Immuron’s proprietary technology is based on polyclonal immunoglobulins (IgG) derived from engineered hyper-immune bovine colostrum. Immuron has the capability of producing highly specific immunoglobulins to any enteric pathogen and our products are orally active. Bovine IgG can withstand the acidic environment of the stomach and is resistant to proteolysis by the digestive enzymes found in the Gastrointestinal (GI) tract. Bovine IgG also possesses this unique ability to remain active in the human GI tract delivering its full benefits directly to the bacteria found there. The underlying nature of Immuron’s platform technology enables the development of medicines across a large range of infectious diseases. The platform can be used to block viruses or bacteria at mucosal surfaces such as the Gastrointestinal tract and neutralize the toxins they produce.

 

 

 

 

 

 

IMM-124E (Travelan®)

 

IMM-124E was developed using Immuron’s platform technology. IMM-124E is produced from the colostrum of birthing cattle that have been immunised during pregnancy with a vaccine containing the outer antigens of multiple human derived ETEC. A total of 13 ETEC strains are used in the vaccine to produce high levels of antibodies against selected surface antigens from the most common strains of ETEC. (Otto et al., 2011)

 

The resultant hyperimmune colostrum IMM-124E from ETEC vaccinated cows contains significant levels of polyclonal antibodies specific for ETEC antigens LPS, CFA-I and Flagellin (Sears et al., 2017).

 

The antibodies produced in IMM-124E have been found to have a stronger binding and neutralizing activity (than the antibodies of unvaccinated cattle) against a wide range of LPS antigens including both the variable O-polysaccharide region and the preserved oligosaccharide core ‘R’ region of LPS from the 13 serotypes used in the ETEC vaccine.

 

IMM-124E is manufactured into a tablet form referred to as Travelan®.

 

IMM-529

 

Immuron is developing IMM-529 as an adjunctive therapy in combination with standard of care antibiotics for the prevention and/or treatment of recurrent Clostridioides difficile infection (CDI). IMM-529 antibodies targeting Clostridioides difficile (C. diff) may help to clear CDI infection and promote a quicker re-establishment of normal gut flora, providing an attractive oral preventative for recurrent CDI.

 

Immuron is collaborating with Dr. Dena Lyras and her team at Monash University, Australia to develop vaccines to produce bovine colostrum-derived antibodies. Dairy cows were immunised to generate hyperimmune bovine colostrum (HBC) that contains antibodies targeting three essential C. diff virulence components. IMM-529 targets Toxin B (TcB), the spores and the surface layer proteins of the vegetative cells.

 

This unique 3-target approach has yielded promising results in pre-clinical infection and relapse models, including (1) Prevention of primary disease (80% P =0.0052); (2) Protection of disease recurrence (67%, P <0.01) and (3) Treatment of primary disease (78.6%, P<0.0001; TcB HBC). Importantly IMM-529 antibodies cross-react with whole cell lysates of many different human strains of C. diff including hypervirulent strains.

 

To our knowledge, IMM-529 is, to date, the only investigational drug that has shown therapeutic potential in all three phases of the disease (Hutton et al., 2017).

 

ProIBS®

 

Immuron has an exclusive distribution agreement with Calmino goup AB for the territories of Australia and New Zealand for ProIBS®. ProIBS® - to help patients treat IBS symptoms ProIBS® is a certified medical device for the treatment of IBS symptoms such as abdominal pain, bloating and unsettled bowel movements (diarrhoea and/or constipation). ProIBS® contains AVH200®, derived from the plant Aloe barbadensis. Mill. AVH200® has gel forming components which support the intestinal mucosal barrier. As IBS is known to affect individuals for a long period of time, it is essential to have a treatment appropriate for long-term use –as ProIBS® is. The product is safe, and no interactions with other medications are known. Science-driven innovative Calmino group AB, the developer of ProIBS®, conducted a usability study among 1,003 users. PROIBS® was helpful for 94% of them. 91% of the users experienced an improvement in daily life and 98% would recommend PROIBS® to someone else. To learn more please check: www.proibs.eu.

Irritable bowel syndrome (IBS) is a common condition where you experience symptoms related to your digestive system. This is sometimes linked to certain foods, lifestyle habits and stress levels or mood. IBS affects around 3 out of every 10 people. Females are more likely than males to be affected. Some key symptoms of IBS include: abdominal pain or discomfort; stomach bloating and wind; chronic diarrhoea or constipation, or alternating between the two.(healthdirect.gov.au) According to available data, the IBS treatment market in Australia is estimated to be a part of the broader “Digestives & Intestinal Remedies” market, generating a revenue of around AU$221.14 million in 2025, with a projected annual growth rate of 3.28%.(Statista)

TAM (Total Addressable Market) The global Traveler’s Diarrhea (TD) market, including all treatments (antibiotics, anti - diarrhea agents) and prevention (vaccines, probiotics). • Global Value : The global Traveler's Diarrhea treatment market is estimated at $3.31 billion for 2026, growing at a CAGR of ~6.8%. • Pathogen Burden : Bacterial pathogens (E. coli, etc.) cause ~80% of cases, which is the specific target for Travelan’s hyper - immune bovine colostrum technology. SAM (Serviceable Addressable Market) The specific segment of travelers visiting high - risk regions who seek prophylactic (preventative) and OTC/Natural solutions rather than acute treatment. • Prevention vs. Treatment : Historically, the "prevention" segment accounts for roughly 25% of the total market, as many travelers rely on acute treatment (antibiotics/Imodium) only after falling ill. • High - Risk Travel : Approximately 20 - 40% of international arrivals (1.52 billion in 2025) are traveling from developed nations to high - risk zones (Africa, SE Asia, Latin America), which constitutes the primary customer base. SOM (Serviceable Obtainable Market) 15 - 20% penetration rate of the “addressable travelers” segment by shifting Travelan from a "niche discovery" to a "standard of care" through the following marketing resources: • The "Treatment to Prevention" Pivot : High - spend marketing (SEO/SEM targeting "Bali belly," "Mexico travel tips," etc.) captures the user at the booking phase, effectively moving them from the Treatment TAM to the Prevention SAM. • Pharmacy & Clinical Detailing : An "appropriate" resource allocation includes a field force to educate pharmacists (who drive the majority of OTC sales). In Australia, where this is already partially active, Travelan accounts for nearly 75% of the niche market; duplicating this in the US/UK is the primary driver of this SOM growth. 6 IMM - 124EMarket Potential

 

 

 

 

The Disease: C. difficile is the leading cause of healthcare - associated infection causing 400,000 cases and 30,000 deaths in the US annually Disease spectrum: • Mild - to - moderate : Watery persistent diarrhea, cramping • Severe/Pseudomembranous Colitis (PMC) : Colon wall plaques • Fulminant CDI : Toxic megacolon, sepsis, and potential bowel perforation, death Who’s at risk: Adults 65+, immunocompromised patients, antibiotic users, and Proton Pump Inhibitors users. Problem with current treatment: Antibiotics eliminate pathogens, indiscriminately disrupt the gut microbiome, hinder flora regeneration, and leave 25% patients vulnerable to recurrent infection within 30 days, rising to 65% after multiple episodes Market opportunity: The diagram represents the funnel from the clinical burden to Immuron's target revenue: • TAM (Total Addressable Market): 100% of all recurrent CDI patients globally at regional pricing. • SAM (Serviceable Addressable Market): The subset of patients expected to be treated with advanced therapy (e.g., FMT, Vowst, Rebyota, or IMM - 529). • SOM (Serviceable Obtainable Market): The peak revenue based on Immuron capturing 30% of the advanced therapy segment. 7 IMM - 529 Market Potential

What are Immuron’s main commercial products and markets?

Immuron markets Travelan to reduce the risk of traveler’s diarrhea and ProIBS for irritable bowel syndrome symptoms. Travelan is sold in pharmacies across Australia and available in Australia, the U.S. and Canada. ProIBS launched in Australia, where HY26 sales reached A$72,000.

How strong is Immuron’s cash position and runway?

Immuron held A$10.0 million in cash as of 31 December 2025, up A$7.2 million from 30 June 2025. Based on HY26 net cash used in operating activities, this equates to roughly 23.5 months of cash coverage, supporting its commercial focus and partnering plans.

What recent clinical and regulatory milestones has Immuron achieved?

IMM-529 received U.S. FDA IND approval, allowing progression to a Phase 2 trial for recurrent C. difficile infection. IMM-124E, based on Travelan technology, is eligible for an end of Phase 2 FDA meeting for traveler’s diarrhea. Immuron also reported topline results from a Uniformed Services University IMM-124E trial.

How are Immuron’s North American sales and distribution evolving?

HY26 North American revenue was A$0.9 million, down 18% year-on-year, though U.S. sales rose 17%. The decline was tied to prior-year Canadian pipeline fill. After HY26, Immuron secured distribution with Jean Coutu, the largest pharmacy chain in Quebec, to support future Canadian growth.
