Espoo, Finland, August 20, 2026: Herantis Pharma Plc ("Herantis") a clinical-stage company developing disease-modifying therapies to stop the progression of Parkinson’s disease, releases today the Company’s 1H 2026 report. The full report is attached to this release and is also available on the Company’s website: www.herantis.com.

Antti Vuolanto, CEO of Herantis Pharma, commented: “The first half of 2026 has been highly productive for Herantis. We reported Phase 1b biomarker data confirming biological activity consistent with HER-096's proposed mechanism, secured important financing and non-dilutive funding, and received encouraging FDA feedback. Combined with the continued refinement of our Phase 2 study design and the appointment of Dr. Juha Savola as Chief Medical Officer, these achievements have further strengthened the scientific and strategic foundation of Herantis and enhanced our readiness for the next stage of development of HER-096. As we move through the remainder of the year, our focus remains on completing preparations for the Phase 2 study while continuing to evaluate opportunities to maximize the potential of HER-096 for patients and shareholders, including continued partnering discussions.”

Herantis will hold a webcast relating to the report and current operations today, Thursday, August 20, 2026, at 10:00 am EEST (09:00 am CEST). The presentation will be delivered in English, followed by a Q&A session. Viewers can submit questions at any time throughout the webcast.

• Successfully completed a directed share issue raising EUR 4.2 million to support Phase 2 preparations and ongoing partnering discussions.
• Selected to lead a consortium that was awarded an EUR 8.0 million Horizon Europe 2025 Research and Innovation grant to support the execution of the planned Phase 2 trial of HER-096 in Parkinson’s disease.
