• Sell-side coverage of Newron has been initiated by four new US and European analysts.
• Post-period, in March 2026, the Company announced that it would propose George Garibaldi and Paolo Zocchi as new, independent, non-executive Board members to the 2026 Annual General Meeting, as Patrick Langlois and Luca Benatti would step down after long-standing service.
• Post-period, in February 2026, the Company entered into an agreement for the subscription of newly issued shares for proceeds of up to EUR 38 million with a group of existing and new shareholders from Europe and Asia, strengthening the Company’s financial position as it advances the ENIGMA-TRS Phase III program.
• Post-period, in March 2026, the Company announced its agreement with the European Investment Bank (EIB) to extend the maturity date of all outstanding tranches under its 2018 Finance Contract to June 28, 2028, subject to the execution of definitive agreements.

Stefan Weber, CEO of Newron, commented: “2025 was a landmark year for Newron, marked by significant headway across our evenamide development program. During this period, we achieved several important milestones, including strong clinical progress, the expansion of our intellectual property portfolio, and the extension of our cash runway. We are extremely proud of what we have accomplished and continue to believe that evenamide is a potential blockbuster, with the ability to deliver meaningful benefits to patients where currently available treatments on the market have failed.”

“We encourage our shareholders to register for and participate in the upcoming Ordinary and Extraordinary shareholders’ meeting on April 23, 2026, as the proposed resolutions are expected to positively contribute to the success of our continuous ambitions, including the preparation of a potential NDA dossier for evenamide and the evaluation of its benefits in additional indications beyond schizophrenia, as well as a potential listing of our shares on a US stock exchange. At this meeting, we will also have the opportunity to thank our meritorious Board members, Patrick Langlois and Luca Benatti, for their dedicated support of our Company over many years. And George Garibaldi and Paolo Zocchi, two highly experienced industry and financial experts, are proposed for election as new, independent members of the Board of Directors,” added Stefan Weber.

Evenamide – advancing schizophrenia treatment

2025 was marked by significant milestones for the evenamide development program, with the approval of the pivotal ENIGMA-TRS Phase III development program evaluating evenamide as an add-on therapy in patients with TRS. This development program consists of two pivotal studies, ENIGMA-TRS 1 and ENIGMA-TRS 2:

• ENIGMA-TRS 1 is an ongoing, international, 52-week, randomized, double-blind, placebo-controlled Phase III study evaluating the efficacy, tolerability, and safety of the 15mg BID and 30mg BID therapeutic doses of evenamide compared to placebo. Patients on second-generation antipsychotics, including clozapine, will meet Treatment Response and Resistance Psychosis international consensus criteria for TRS. The study will enroll at least 600 patients at study centers in Europe, Asia, Latin America and Canada. The first patients were successfully enrolled in August 2025, following the completion of a rigorous 42-day screening period. Patients are currently being enrolled across eight countries on all target continents.

The primary assessment of efficacy and safety of ENIGMA-TRS 1 will be performed 12 weeks after randomization to treatment. Following this initial period, the study will continue double-blind and placebo-controlled until the 26- and 52-week time points. The primary efficacy endpoint of the trial will be the change from baseline in the Positive and Negative Syndrome Scale (PANSS) scores at 12 weeks. Newron expects to announce results from the 12-week primary endpoint assessment in QIV 2026..

• ENIGMA-TRS 2 is taking place at centers in the US and selected additional countries with the same screening procedure as the ENIGMA-TRS 1 trial. ENIGMA-TRS 2 will include at least 400 patients in a 12-week, randomized, double-blind, placebo-controlled Phase III study, designed to evaluate the efficacy, tolerability, and safety of the 15mg BID dose of evenamide compared to placebo. In December 2025, ENIGMA-TRS 2 was initiated in the US, following approvals from the US Food and Drug Administration (FDA) and the Institutional Review Board (IRB). The first sites to initiate were the Semel Translational Research Center for Neuropsychiatry at the University of California, Los Angeles (UCLA), and the Johns Hopkins University School of Medicine (Baltimore), with the three more sites in the US being fully approved and expected to start enrolling shortly. Regulatory submissions are currently being made in the other countries that are expected to participate in this trial in the coming months, with first approvals having been received. The efficacy and safety analysis will be performed at the 12-week point following successful completion of the study.

Post-period, in January 2026, Newron shared the announcement that its partner for Japan and other designated Asian territories, EA Pharma (Eisai Group), had initiated its Phase III clinical trial with evenamide in Japan.

In August, new data from Dr. Anthony Grace and other researchers at the University of Pittsburgh was published in the peer-reviewed journal “International Journal of Neuropsychopharmacology”. The data suggests that evenamide ameliorates schizophrenia-related dysfunction, and for the first time demonstrates that evenamide targets the key site of schizophrenia pathology in the hippocampus. Researchers demonstrated that evenamide could offer a novel therapeutic strategy capable of addressing the positive, cognitive, and negative symptoms of schizophrenia, a key advantage over existing antipsychotic drugs which only target positive symptoms. These findings help explain the robust and sustained symptom improvements observed in Newron’s Phase II and Phase III studies in patients with chronic schizophrenia, reinforcing evenamide’s potential as a transformative therapy for treatment-resistant and poorly responding patients, and offering a promising alternative to traditional dopamine D2-based antipsychotics.

Newron’s R&D team also used the reporting year to present and discuss data on the mechanism of action of evenamide in scientific publications, such as the “International Journal of Neuropsychopharmacology”. Post-period, in February 2026, peer-reviewed data co-authored by Newron’s Chief Medical Officer, Ravi Anand, MD, and colleagues was also published in “Therapeutic Advances in Psychopharmacology”. The publication collated results from multiple randomized clinical trials and provided a scientific mechanistic rationale for the use of evenamide as a unique approach that targets disease mechanisms not addressed by existing antipsychotics. Furthermore, throughout 2025, Newron presented new analyses from its evenamide clinical development program at key conferences, including the 2025 World Congress of Biological Psychiatry in September and the 38th European College of Neuropsychopharmacology Congress in October.

To comprehensively protect the future value of evenamide for existing shareholders and new investors, Newron is filing additional patent applications to further extend the IP protection for evenamide as a novel treatment for schizophrenia. These additional patents would complement the existing patent applications pertaining to evenamide which continue to be granted within the European Union and the US. In January 2026, just after the end of the reporting period, the European Patent Office issued the decision to grant the Company an additional patent until 2044 for evenamide. The patent covers crystalline forms of evenamide, processes for their preparation, and their uses. This is an important milestone for Newron, and the decision is likely to extend evenamide’s exclusivity runway, helping to maximize its therapeutic and commercial potential.

In addition to its licensing agreements with Myung In Pharm and EA Pharma, the Company’s Board and Management are actively exploring additional global development and commercial opportunities for evenamide and will prioritize and negotiate any offers based on their potential to increase shareholder value.

Financial key takeaways 2025:

• In 2025, Newron reported a license income of EUR 8.6 million (2024: EUR 44.5 million), resulting from the upfront payment due under the license agreement signed with Myung In Pharm Co. Ltd. and milestones from both EA Pharma (Eisai Group) and Myung In.
• In addition, the Company received royalty payments for Xadago® from Zambon of EUR 7.8 million (2024: EUR 6.9 million) and booked Other revenues for a total of EUR 2.7 million.
• Newron’s R&D expenses increased to EUR 15.1 million (from EUR 13.6 million in 2024).
• As a result, in 2025 Newron reported a net loss of EUR 13.2 million, compared with a net profit of EUR 15.8 million in 2024 (due to the upfront payment received under the license agreement signed with EA Pharma in December 2024).
• As the EA Pharma (Eisai Group) upfront payment was received in January 2025, only, Operating activities generated EUR 32.3 million of cash, while in 2024 Operating activities used EUR 17.6 million.
• Cash and Other current financial assets as of December 31, 2025 were at EUR 28.9 million, compared to EUR 9.8 million at the beginning of the year.

Outlook 2026

Newron’s and evenamide’s progress in 2025 was highly encouraging, and the Company is well-positioned to build on this momentum in 2026, as the pivotal ENIGMA-TRS 1 and 2 trials advance, with initial pivotal data readout expected later this year. Progressing the evenamide clinical development program is the key priority for 2026, and Newron remains resolutely committed to delivering meaningful benefits to patients who urgently need innovative treatment options that address gaps in current therapeutic approaches.

The Company maintains a strong financial position, strengthened by the agreement for the subscription of newly issued shares in February 2026, which enables Newron to continue operating as a sustainable business. Newron’s total available cash resources together with the EUR 15 million of proceeds from shares newly issued in February 2026, plus an additional EUR 11 million expected under the financing agreement before the end of 2026, should fund the Company's planned development programs and operations well through 2027.
