Ghent, BELGIUM – 18 September 2025, 07:00 CEST – Biotalys (Euronext - BTLS) today announces its key business achievements and consolidated financial results for the first half of 2025, prepared in accordance with IFRS as adopted by the European Union. The complete half-year report including the interim financial results is available here.

Kevin Helash, Chief Executive Officer of Biotalys, stated: "In the first half of the year, we achieved meaningful milestones in our mission to bring sustainable precision biocontrols to market. Building on our close cooperation with regulators in the United States and Europe, we made significant advancements in the approval process of our first biocontrol candidate, EVOCA, and we remain optimistic that favourable decisions are within sight.

We also advanced our pipeline and solidified a number of key elements of our commercialization strategy to support market entry of our portfolio, including the important new partnership for postharvest biobased solutions with leading player AgroFresh. Looking ahead, we will continue to take a disciplined, cost-conscious approach and evaluate additional financing opportunities to effectively execute our strategy and further exploit the potential of our unique technology platform to develop precision biocontrols."

Regulatory update for EVOCA (including post-period information)

Biotalys has continued to work closely with the EPA (Environmental Protection Agency) in the United States and the CTGB (the Dutch Board for the Authorisation of Plant Protection Products and Biocides) in Europe to move the regulatory review process for EVOCA forward.

• In the United States, Biotalys received further guidance from EPA end of August, in which the agency confirmed that the scientific review of the dossier is progressing, and that all the previous requests for additional information have been addressed. While the agency continues to work on the review, the company now expects the final steps of the registration procedure to be taken in Q4.
• In Europe, both the CTGB and the Dutch Institute for Health and Environment (RIVM) paved the way for the peer review phase at the European level by providing positive evaluations of EVOCA's

regulatory dossier in June. As no critical areas of concern were identified and it was proposed to classify EVOCA's active ingredient as low risk, the Netherlands, as rapporteur Member State, proposed its approval in Europe, subject to the provision of certain additional data during the peer review phase.

H1 2025 R&D update (including post-period information)

• In May, Biotalys announced a strategic partnership with AgroFresh Solutions, Inc. to develop and commercialize biological solutions for post-harvest use to protect fresh produce. As fungal decay remains one of the most persistent and complex challenges in the post-harvest supply chain, sustainable freshness solutions are especially critical for high-value and highly perishable crops. Demonstrating the versatility of its protein-based AGROBODY™ platform to help preserve food quality without chemical residues, Biotalys will work with AgroFresh to provide sustainable solutions that keep food fresher for longer and reduce global food waste.
• In March, Biotalys announced that one of the lead candidates for BioFun-6 the company's second biofungicide program targeting botrytis, powdery mildew – demonstrated strong efficacy at lower dosage rates than EVOCA in trials in both Europe and the United States. The same candidate also performed well in independent academic trials by UC Davis in California (see here for the full results). Biotalys plans to test a second lead candidate in its field trial program this coming season to allow the company to select the best candidate for further development on its platform.
• Biotalys continued its work on its other pipeline programs in the discovery phase:
  • o BioFun-4, targeting Phytophthora infestans, an Oomycete (water mould) that causes late blight/potato blight, where the company has an ongoing collaboration with the University of Aberdeen;
  • o BioFun-7, the R&D program in partnership with the Gates Foundation targeting leafspot disease, where Biotalys has entered into a collaboration with the International Institute of Tropical Agriculture (IITA) in Nigeria, next to its existing collaboration with the University of California-Davis;
  • o BioFun-8, its most recent pipeline product against Alternaria; and
  • o BioIns-2, its bioinsecticide program in collaboration with Syngenta Crop Protection.

H1 2025 corporate highlights (including post-period information)

• Biotalys appointed Luc Van fraeyenhoven as Chief Financial Officer in May. With a strong background leading finance operations and strategy in the biotechnology and medtech industries, he provides seasoned financial guidance on both long-term strategies and day-to-day finance operations.
• In March, Biotalys appointed seasoned agriculture and biotech executive Toni Bucci to its Board of Directors. Her passion for innovation, extensive experience in agriculture and strategic leadership helps the company navigate critical next steps in its path to commercialization and accelerate its impact in sustainable agriculture.
• Biotalys strengthened its patent position and obtained patent protection for EVOCA in Brazil and China. In Brazil, the patent examination process was accelerated under the Patentes Verdes ("Green Technology") initiative to accelerate the examination of patent applications relating to

technologies having a positive impact on the environment. The company also recently obtained a patent grant in the U.S. for one of its active ingredients developed in its BioFun-6 program.

• Early in 2025, Biotalys earned Top 50 status in Forward Fooding's FoodTech 500 list, climbing to #32. FoodTech 500 ranks global innovators at the intersection of food, technology and sustainability.

• Other operating income for the first half of 2025 amounted to €1.4 million, in line with the same period last year, and mainly related to amounts recognized for R&D tax incentives received and grants awarded to support ongoing R&D activities.
• Research and development expenses amounted to €6.5 million for the first half year, an increase of €1.4 million compared to the same period of 2024. The increase primarily related to higher costs for external R&D, to further advance pipeline projects, partially offset by lower spending for EVOCA while pending regulatory approval.
• General and administrative expenses amounted to €3.0 million for the first half of 2025, a slight increase of €0.1 million compared to the same period of 2024, related in part to indexation of salaries.
• Net cash used in operating activities amounted to €6.1 million for the six months ended 30 June 2025, €0.4 million lower than in the same period last year.

Outlook

• Biotalys plans to continue focusing on earning regulatory approvals for EVOCA in the US and Europe, and on the submission of a regulatory dossier in Brazil. The company envisages building on these first approvals with the preparation of regulatory dossiers for its commercial version EVOCA NG, which are expected to have a shorter review timeline than the standard procedures.
• Biotalys made substantial progress in its commercial set-up for EVOCA NG, and expects to finalise its ongoing discussions with various partners regarding commercial production and distribution of EVOCA NG in the near term.
• Based on the company's precision biocontrol platform approach, Biotalys plans to further develop its pipeline of candidate products in collaboration with key academic and industry partners.

• With a cash and cash equivalents balance of €15.7 million at the end of H1 2025, the company intends to maintain a cost-conscious approach and to consider additional financing to effectively execute its strategy and further exploit the potential of its unique technology platform to develop precision biocontrols.
