Stephan is expected to continue to work closely with Gael and the Board as an advisor through the end of the year to help ensure a seamless transition as the company enters its next phase of growth. Stephan intends to retire from Aptar’s Board by the end of 2026 and the Board will appoint Gael as a director on September 1, 2026.

“Gael has played a pivotal role in shaping Aptar Pharma’s strategic direction, expanding our technologies and services to support customers from formulation to patient. His global experience and deep understanding of each of Aptar’s businesses, core technologies and end markets make him uniquely equipped to lead the company forward. Gael has helped advance our leadership in regulated drug delivery and the Board believes he can bring the strategic clarity and operational discipline needed to extend that success across our consumer segments. Following a thorough succession planning and selection process that considered both internal and external candidates, the Board unanimously concluded that Gael was the best choice to lead Aptar into its next chapter. The Board has full confidence in his vision for the Company,” said Candace Matthews, Chairperson of AptarGroup.

“I am honored to step into this role,” said Gael Touya, President of Aptar Pharma, and President and CEO Designate of AptarGroup. “Aptar has been my professional home for more than 30 years, and I am energized by the opportunity to help shape the Company’s future alongside our global teams. Our purpose could not be more meaningful, and I am committed to building on our strengths while listening closely to our people, customers, and partners. I want to thank Stephan for his outstanding leadership and the foundation he has built for our continued success.”

Gael Touya: A Proven Leader Positioned to Accelerate Aptar’s Next Chapter

With over three decades at Aptar across Europe, Asia, and North America, Gael brings deep commercial, operational, and technical expertise, paired with a global mindset and a strong track record of results. Since 2018, Gael has served as President of Aptar Pharma and has guided the segment’s transformation into a more comprehensive, science‑driven, and digitally enabled partner to many of the world’s leading pharmaceutical companies. Under his leadership, the segment has expanded significantly, achieving approximately 82% topline growth during this period.

During Gael’s tenure, Aptar Pharma has advanced a clear vision of supporting customers at each stage of development with the patient at the center. He led the expansion of the segment’s technologies and services to create an integrated, end‑to‑end model designed to help customers move from early formulation through clinical development and commercialization with greater efficiency. This approach combined well targeted and executed acquisitions with strategic organic development and focused innovation. He worked to strengthen Aptar Pharma’s offering by adding regulatory expertise, clinical development support, patient onboarding and digital health capabilities intended to improve adherence. During his tenure, the segment also expanded respiratory and nasal drug delivery beyond traditional local treatments into systemic applications for therapeutic areas such as depression, seizures and migraines, and advanced nasal delivery technologies from small‑molecule use cases into larger and more complex molecules, including biologics.

These strategic investments, combined with his focus on customer partnership and operational excellence, have helped reinforce Aptar Pharma’s position as a leader and a trusted global partner in regulated drug delivery.

Gael also brings a deep understanding of Aptar’s broad portfolio, having previously served as President of Aptar Food + Beverage (now Aptar Closures), President of Food + Beverage Europe, Vice President of Business Development for Skincare and Color Cosmetics (now part of Aptar Beauty), and leadership assignments in India where he helped establish Aptar’s pharmaceutical office and business. He also held full P&L responsibility in China and Japan, where he led the expansion of Aptar’s presence in key high‑growth markets. Known for his people‑centered leadership, Gael is deeply committed to talent development, sustainability and fostering a culture of innovation across regions and teams.

“Gael is uniquely qualified to take on the role of President and CEO. His global perspective, strong commercial and operational background, and deep understanding of Aptar’s businesses position him to drive our next chapter of growth,” said Stephan Tanda, President and CEO of Aptar.

Gael holds a degree in business and international management from Excelia Business School in France, an MBA from ESSEC Business School in France, and has completed multiple executive leadership programs, including the Harvard Business School Advanced Management Program. His leadership philosophy is grounded in curiosity, collaboration and creating lasting impact for patients, consumers and customers worldwide.

Honoring Stephan Tanda’s Remarkable Tenure as CEO

Aptar also recognizes the outstanding leadership of Stephan Tanda, whose tenure as CEO since 2017 has been defined by performance, purpose, and global expansion, both organically and some 20 bolt on acquisitions and investments, with the majority being in Pharma, including the acquisition of the Active Material Science business in 2018.

Since 2017 under Stephan’s leadership, adjusted EBITDA margins expanded from approximately 19% for the yearend 2017 to approximately 22% for the yearend 2025, adjusted earnings per share grew 67% with the majority of capital allocated to Pharma, helping establish it as Aptar’s largest and most profitable segment. During this time, capital returned to shareholders increased approximately 100%. In 2025, Aptar marked its 32nd consecutive year of paying an annually increasing dividend.

Stephan shared, “I am profoundly grateful to our employees, customers, stakeholders and Board for their trust and support during my tenure. Leading Aptar has been an immensely rewarding experience, and I appreciate the continued partnership with Gael that has strengthened our company and advanced our mission.”

Stephan also accelerated Aptar’s global footprint in high‑growth regions across Asia, Latin America, Africa and the Middle East; advanced operational excellence and cost discipline; and cemented Aptar’s leadership in sustainability, receiving more than 95% of global electricity consumption from renewable sources, expanding recycled content, advancing circularity initiatives and earning recognition from TIME, CDP and Barron’s.

Perhaps most importantly, Stephan championed Aptar’s culture - reinforcing inclusion, leadership development, community impact, and the company’s enduring commitment to safety and purpose.
