3 Third quarter 2025 Highlights BioChaperone® Lispro in China: Positive Phase 3 topline results in Type 2 and Type 1 Diabetes Partner Tonghua Dongbao initiated two Phase 3 studies with Ultra-Rapid Insulin BioChaperone ® Lispro with about 1,500 people with Type 1 or Type 2 Diabetes in 2022. The final dosing of the last Type 2 Diabetes patient was announced on December 12, 20242, triggering a US$10 million milestone payment (net of US$9 million after 10% withholding tax) received in July 2025. In July 2025, Adocia and Partner Tonghua Dongbao announced positive topline results of this Phase 3 in people with Type 2 Diabetes 3, demonstrating a non -inferior HbA1c reduction at 26 weeks compared to Humalog ® (primary endpoint) and a significant reduction in the rise of blood glucose after a test meal (key secondary endpoint). Mean blood glucose level over the day monitored by 10 -point Self -Monitoring of Blood Glucose (SMBG), an important supportive endpoint, was also significantly decreased, in comparison with Humalog ®. In October 2025, Adocia and Tonghua Dongbao announced positive topline results of this Phase 3 in people with Type 1 Diabetes 4. BioChaperone® Lispro successfully demonstrated in people with Type 1 Diabetes non- inferior HbA1c reduction at 26 weeks compared to Humalog®, achieving the primary endpoint, and a significant reduction in the rise of blood glucose after a test meal, achieving a key secondary endpoint. Blood glucose level, monitored by 10-point SMBG, was statistically decreased 1 hour after each meal in comparison with Humalog®. The contract with Tonghua Dongbao includes a milestone payment of US$20 million, which would be triggered upon obtaining marketing authorization in China, and subsequent double -digit royalties on sales to Adocia. The marketing authorization application is under Tonghua Dongbao’s responsibility. BioChaperone® GLP-1 – Amylin / BioChaperone® CagriSema: Combining next-generation obesity products BioChaperone® CagriSema offers a stable combination of cagrilintide and semaglutide compatible with a multi- use pen. Data generated to date are promising regarding its commercial and manufacturing benefits over the combination of cagrilintide and semaglutide currently being developed by Novo Nordisk which, for now, requires each peptide to be in separate chambers, of a single-use pen device. BioChaperone® CagriSema offers significant manufacturing and usage advantages. Using an existing multi -dose pen makes it possible to replace four auto - injectors for four weeks of treatment with a single pen, and moreover, such a pen offers dosing flexibility, which could represent a future evolution for these hormonal treatments. Adocia will present the latest preclinical results obtained with BioChaperone ® CagriSema at the next PODD annual meeting (Partnership Opportunities in Drug Delivery - Boston, USA, 27-28 October 2025). The BioChaperone ® technology is currently being evaluated for other difficult to formulate peptides. The company’s priority is to conclude a partnership for this technology. 2 Press Release, Dec. 12, 2024, ADOCIA and Tonghua Dongbao Announce the Final Dosing in a Phase 3 Clinical Study of BioChaperon e® Lispro, Milestone Associated with a $10 Million Payment 3 Press Release, July 25, 2025, ADOCIA and Tonghua Dongbao Announce Positive Topline Results of Phase 3 Clinical Trial on Ultra -Rapid Insulin BioChaperone® Lispro (THDB0206 injection) in people with T2D 4 Press Release, October 15, 2025, ADOCIA and Tonghua Dongbao Announce Positive Topline Results of Phase 3 Clinical Trial on Ultra-Rapid Insulin BioChaperone® Lispro (THDB0206 injection) in people with T1D

4 M1Pram : Exclusive option right in force for M1Pram with Sanofi, discussions about this partnership are still ongoing M1Pram is a fixed combination of insulin and amylin analogs aimed at addressing the unmet medical need of obesity in insulin-dependent individuals. Adocia granted Sanofi an exclusive right to negotiate a partnership on M1Pram for €10 million5. Discussions about this partnership are still ongoing. A Phase 2b clinical program in the United States, involving 140 patients with Type 1 Diabetes and a BMI6>30kg/m², has been prepared. Adocia has completed the manufacturing of clinical batches of M1Pram. The launch of this clinical trial is conditional on the signing of an agreement on the product. AdoShell®: Proof-of-concept in vivo on insulin -secreting stem cells and AdoShell® Islets: Progressing toward Clinical Trial submission The innovative AdoShell ® technology platform is designed to implant human insulin -secreting cells from either deceased donors (islets of Langherans) or stem cells to provide a cure for Type 1 Diabetes without immunosuppression. Adocia presented its latest preclinical data on AdoShell® technology at two scientific conferences in September: the 34 th Annual Conference of the European Society for Biomaterials (ESB 2025) and the 61 st EASD Annual Meeting (European Association for the Study of Diabetes). The results highlight the major progress achieved with the AdoShell® platform7. The in vivo and in vitro proof-of-concept on insulin-secreting stem cells has been established. The in vitro and in vivo maturation of islets derived from immature stem cells in AdoShell ® was demonstrated. The long -term functionality and efficacy of these encapsulated islets were confirmed in vivo. Preparatory work to submit a clinical trial application to the regulatory authorities for AdoShell ® with human islets has progressed and the clinical trial submission is expected in Q3 2026. AdOral®: Delivering peptides in oral form to replace injections Adocia has developed an oral delivery technology for peptides, enabling the transition from injectable to oral forms, and has achieved promising preclinical results on semaglutide (GLP -1). Data on AdOral ® Sema was presented at the ATTD 2025 conference (18 th International Conference on Advanced Technologies & Treatments for Diabetes, 19-22 March, 2025, Amsterdam, The Netherlands). The only GLP-1 commercially available in oral form to date, Rybelsus ®, achieved US$3.4 billion in global sales in 2024 and approximately US$1.8bn in H1 20258. Oral delivery is a key factor in increasing patient adherence for those with diabetes and/or obesity. Yet, the poor bioavailability of peptides orally administered requires the production of extremely large quantities of peptides, leading to high cost of goods sold and a supply chain limited 5 Press Release, July 5, 2023, ADOCIA Grants Sanofi an Exclusive Right to Negotiate a Partnership on M1Pram for 10 Million Euro s and Obtains Commitment from Investors to Provide 10 Million Euros in Financing 6 BMI stands for Body Mass Index, calculated as the mass of a person in Kg, divided by the square of its height in meters 7 Press release of June 24, 2025 - ADOCIA Presentations at ADA & IPITA Scientific Conferences Highlight Scalability and Good Translation of AdoShell® from Human Islets to Stem Cell-Derived Islets. 8 Derived from Novo Nordisk FY2024 and H1 2025 reports

5 by limited manufacturing capacity. Adocia’s AdOral ® technology has demonstrated so far to have improved bioavailability, suggesting that for the same peptide manufacturing capacity, more patients could be treated at a much lower cost of goods sold. AdOral ® technology has also demonstrated a much narrower inter -patient variability in terms of oral peptide absorption, suggesting a potential better control of the pharmacokinetic profile of the peptides orally administered via the AdOral® technology compared to the existing technologies. From 2026, semaglutide will be off -patent in many countries, and many companies are preparing to launch biosimilars of Ozempic (subcutaneous). This situation creates an opportunity for AdOral® Sema, as this patented product will have freedom to operate. The AdOral® technology is currently undergoing an R&D collaboration agreement with an undisclosed partner for an application to a novel incretin. All costs related to this agreement are covered by the partner. AdoGel®: Long-acting peptide delivery to reduce injections Adocia has decided to put the AdoGel® project on hold in order to concentrate its technical efforts on AdoShell®, BioChaperone®, BC CagriSema, and AdOral®.
