Decoy Therapeutics Stockholders Elect Patricia Gauthier to Board of Directors

CAMBRIDGE, Mass., July 15, 2026 /PRNewswire/ -- Decoy Therapeutics Inc. (Nasdaq: DCOY), a biotechnology company pioneering Designable Multi-Antivirals (D-MAVs™), a new category of antivirals engineered to target shared viral mechanisms, today announced that stockholders elected Patricia Gauthier, MBA, LL.B., as a Class II director at the Company's 2026 Annual Meeting of Stockholders, held July 14, 2026 Ms. Gauther will serve with the Company's other two Class II directors, Rick Pierce and Jon Lieber, each of whom were re-elected at the annual meeting.

"Patricia has spent her career making sure important medicines reach the people who need them, at scale and in the real world. We're glad to welcome her to the Board as we advance our D-MAV programs toward the clinic," said Rick Pierce, Chief Executive Officer of Decoy Therapeutics. "Her experience building commercial organizations and delivering medicines across borders will help us turn a new approach to antiviral disease into real-world impact."

Ms. Gauthier has served as Senior Vice President, Regional Head for Australia, Canada and the United Kingdom at Moderna since 2025, leading strategy and operations across biomanufacturing, national health security partnerships and commercialization. She previously served as General Manager of Moderna Canada, where she built the affiliate from inception, supported the delivery of more than 50 million COVID-19 vaccine doses, and helped secure a biomanufacturing partnership with the Government of Canada. She also held senior leadership roles at GSK across vaccines, specialty care, market access and government affairs, and began her career as a lawyer at McCarthy Tétrault.

"What Decoy is building could change how we prepare for viral threats before they emerge," said Patricia Gauthier, MBA, LL.B. "A single adaptable drug, designed to work across related viruses by targeting shared mechanisms, is a more flexible answer than developing one antiviral at a time. Having spent my career getting medicines to people at scale, across markets, manufacturing and health systems, I've learned the science is only half the challenge. The other half is making sure it reaches patients. That's the work I'm looking forward to helping Decoy do as these programs move toward the clinic."
