Alvotech announces planned CEO succession and leadership transition

• Róbert Wessman to continue serving as Executive Chairman in full-time capacity
• Lisa Graver appointed Chief Executive Officer

REYKJAVIK, ICELAND (January 6, 2026) — Alvotech (NASDAQ: ALVO), a global biotechnology company specializing in the development and manufacture of biosimilar medicines for patients worldwide, today announced key senior leadership changes following a planned succession process. Founder Róbert Wessman, who has served as Chairman since the company’s inception in 2013 and Chief Executive Officer since 2023, will transition out of the CEO role at the end of the first quarter of 2026. He will continue to serve as Executive Chairman in a full-time capacity. Lisa Graver has been appointed as his successor as Chief Executive Officer.

“When I stepped into the CEO role at the beginning of 2023, it was with a clear objective to strengthen day-to-day leadership and position the company for its next phase. My intention was not to combine the roles of Chairman and CEO on a long-term basis, and the Board and I have been planning for a CEO succession accordingly for some time,” said Róbert Wessman.

“As we move into the next phase of the Company’s development, it is important that Alvotech’s leadership is based in Iceland alongside our core operations. Lisa has been a trusted partner to me for more than 20 years and brings deep leadership experience and understanding of this business. She has the full support of our Board to build on our strong foundations and lead Alvotech forward.”

“As Executive Chairman and the company’s largest shareholder, I am fully committed to Alvotech’s success and will focus on strategy, business development, portfolio direction, capital markets and corporate governance. We have built a world-class R&D and manufacturing platform, and a pipeline that currently includes 30 products in development and ranks among the most valuable in the industry. We now have five products on the market that are sold globally. I am hugely energised about the prospects for the business.”

“I am honored to have the opportunity to serve as Chief Executive Officer of Alvotech at this important stage of the company’s development,” said Lisa Graver. “Alvotech has built a differentiated platform, a clear strategy and a strong culture. Having spent considerable time in Iceland over the past 20 years, I am excited for this to be my new professional home base. I look forward to working closely with the leadership team and my colleagues across the organisation to continue executing on the company’s priorities and driving the next phase of growth.”

Ms Graver brings extensive leadership and operational experience within the global pharmaceuticals sector and has worked closely with Mr Wessman for more than two decades. She served as Chief Executive Officer of Alvogen until its acquisition by Lotus Pharmaceutical in December 2025, and as a member of Alvotech’s Board since its public listing in 2022.

The transition process will begin immediately, with Ms Graver working closely with Mr Wessman and the executive team over the coming months to ensure continuity and a smooth handover. Upon assuming the Chief Executive Officer role, she will step down from the Alvotech Board.
