**Immunic Strengthens Its Board of Directors with the Appointment of Seasoned Biopharmaceutical Executive Jon Congleton**

 

*– Nearly 40-Year Biopharmaceutical Professional with Deep CNS and Commercial Leadership Experience in Multiple Sclerosis –*

 

*– Served on Original Team Responsible for the Launch of Copaxone® in the United States –*

 

**NEW YORK, March 31, 2026 – Immunic, Inc. (Nasdaq: IMUX)**, a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases, today announced the appointment of Jon Congleton, a seasoned biopharmaceutical executive with nearly 40 years of experience spanning drug development, commercialization and corporate leadership, to its Board of Directors, effective March 27, 2026.

Mr. Congleton has a strong track record of building and leading biopharmaceutical organizations and advancing innovative therapies. During his career, he has worked across cardiovascular, gastrointestinal, and central nervous system (CNS) organizations, with a focus on delivering solutions for patients and their caregivers. He played a key role in the U.S. launch of Teva Pharmaceuticals Industries Ltd.'s Copaxone®, a subcutaneous injection treatment for relapsing forms of multiple sclerosis (MS), and led the U.S. operations when it became the number one prescribed MS treatment.

Mr. Congleton currently serves as Chief Executive Officer (CEO) and member of the Board of Directors of Mineralys Therapeutics, Inc., focused on aldosterone-driven cardiorenal conditions. As CEO, he guided the company from an early-stage private entity to the publicly traded, pre-commercial biotechnology firm it is today. Previously, he served as CEO and Board member of both CNS company Impel NeuroPharma, Inc. and cystic fibrosis company Nivalis Therapeutics, Inc.. Earlier, Mr. Congleton held several senior leadership roles at Teva Pharmaceuticals, eventually leading its United States and Canadian neuroscience businesses and global CNS franchise.

"MS remains a devastating disease for the patients and their families. Jon's deep CNS expertise and proven track record in late-stage drug development and commercialization will be invaluable as we advance vidofludimus calcium through its pivotal clinical milestones and toward potential regulatory approval and commercial launch," stated Simona Skerjanec, M.Pharm, MBA, Interim Chairperson of the Board of Directors of Immunic. "I am thrilled that Jon is joining us at this critical moment as we evolve our Board to support Immunic in its transition into a fully integrated commercial-stage company."

"I am excited to join Immunic's Board at such a pivotal moment for the company's MS program," added Mr. Congleton. "Vidofludimus calcium represents a potentially transformative opportunity for MS patients, offering advantages over currently available therapies, particularly with its unique combination of neuroprotective, anti-inflammatory and anti-viral effects as well as its favorable safety and tolerability profile shown to date. I look forward to working with the Board and the leadership team and contributing my experience to support Immunic as it advances toward the pivotal trial readouts later this year and long-term value creation."

**About Immunic, Inc.**

Immunic, Inc. (Nasdaq: IMUX) is a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases. The company's lead development program, vidofludimus calcium (IMU-838), is currently in phase 3 clinical trials for the treatment of relapsing multiple sclerosis, for which top-line data is expected to be available by the end of 2026. It has already shown therapeutic activity in phase 2 clinical trials in relapsing-remitting multiple sclerosis, progressive multiple sclerosis and other diseases. Vidofludimus calcium combines neuroprotective effects, through its mechanism as a first-in-class nuclear receptor-related 1 (Nurr1) activator, with additional anti-inflammatory and anti-viral effects, by selectively inhibiting the enzyme dihydroorotate dehydrogenase (DHODH). The company's development pipeline also includes earlier-stage programs, including IMU-856 and IMU-381, aimed at building a broader therapeutics platform addressing neurodegenerative, chronic inflammatory, and autoimmune-related diseases.
