Exhibit 99.1

Madrigal Appoints John C. Reed, M.D., Ph.D., to its Board of Directors

CONSHOHOCKEN, Pa., August 12, 2026 – Madrigal Pharmaceuticals, Inc. (NASDAQ: MDGL), a biopharmaceutical company focused on delivering novel therapeutics for metabolic dysfunction-associated steatohepatitis (MASH), today announced it has appointed John C. Reed, M.D., Ph.D., to its Board of Directors.

Dr. Reed currently serves as Executive Vice President, Innovative Medicine, Research & Development at Johnson & Johnson (“J&J”) and is a member of J&J's Executive Committee, where he leads research and development across oncology, immunology, neuroscience and other areas of significant unmet medical need.

Julian Baker, Chairman of the Board of Directors of Madrigal, stated, "I am pleased to welcome John Reed to Madrigal. John is one of the biopharma industry’s most accomplished physician-scientists and research leaders, with an extraordinary track record of advancing innovative medicines and building premier research organizations. His deep scientific expertise, strategic leadership and global experience developing breakthrough therapies will be invaluable as Madrigal continues to grow and expand its leadership in MASH."

Bill Sibold, Chief Executive Officer of Madrigal, added, "John's appointment reflects Madrigal's continued commitment to scientific excellence and long-term innovation. As we build on the successful launch of Rezdiffra and advance our industry-leading MASH pipeline, John's insights across drug discovery, translational medicine and global R&D strategy will be an important asset to our Board and management team."

Prior to joining Johnson & Johnson in April 2023, Dr. Reed held executive leadership positions at Sanofi and Roche, serving on their respective executive committees. Earlier in his career, he served as President and Chief Executive Officer of Sanford-Burnham Medical Research Institute (now Sanford Burnham Prebys), where he established multiple disease-focused research centers and platform technology organizations.

An internationally recognized leader in biomedical research, Dr. Reed has authored more than 900 scientific publications, holds more than 130 patents and has been consistently recognized among the world's most highly cited researchers in life sciences and medicine. He is a Fellow of the American Association for the Advancement of Science and has received numerous awards recognizing his contributions to biomedical research and innovation. He earned a Bachelor of Arts in Chemistry from the University of Virginia and both his M.D. and Ph.D. in Immunology from the University of Pennsylvania School of Medicine.
