"BeOne represents more than a name change—it's not only a reflection of who we are today as a leading global oncology company, but also our ambition to redefine what's possible in oncology as we unite patients, families, scientists, physicians, governments, and other oncology public health stakeholders around the world in our shared mission against cancer," said John V. Oyler, Co-Founder, Chairman and CEO at BeOne. "While I know that our work is not done, I am extremely proud of the progress we have made with the explosive growth of BRUKINSA as the backbone of our hematology franchise, the expansion of our PD-1 inhibitor, TEVIMBRA, and our potentially transformative oncology pipeline of more than 50 investigational assets, one of the most prolific in the industry. After 15 years of relentless innovation and strategic investment to boost our internal global capabilities, we are just getting started, and I look forward to working together as BeOne."

The new name and redomiciliation to Switzerland from the Cayman Islands were approved by shareholders on April 28. The transition to the BeOne name across the Company's worldwide operations on six continents will happen in phases. The redomiciliation to Switzerland strengthens BeOne's presence and deepens its roots in a global biopharmaceutical hub, further enabling its growth strategy of bringing innovative medicines to patients around the world.

Industry-Leading Innovation and Global Scale

BeOne has built a differentiated and sustainable advantage through strategic investments to bolster its internal research, clinical development, and manufacturing capabilities. This unique model harnesses time and cost efficiencies to improve patient access, enables close oversight to enforce high standards across R&D and manufacturing, and safeguards our operational resilience for long-term growth. BRUKINSA has the broadest label in its treatment class and leads in new patient starts across all of its approved indications in the U.S. It also is the cornerstone of BeOne's hematology franchise as a foundational treatment alongside late-stage BCL2 inhibitor sonrotoclax and potential first-in-class BTK protein degrader, BGB-16673, which was developed from the Company's proprietary CDAC platform. BeOne also is focused on building future solid tumor franchises in breast, lung, and gastrointestinal cancers. By leveraging its platforms in multi-specific antibodies, protein degraders and antibody-drug conjugates, the Company is positioned to transform the future of oncology treatment.

BeOne's entrepreneurial research team, comprising more than 1,100 colleagues, advanced 13 new molecular entities into the clinic in 2024 alone, outpacing even the largest pharmaceutical companies. Further, its nearly 3,700-strong clinical development team has active or planned trials across more than 45 countries and regions, accelerating early-stage innovation through its "Fast to Proof-of-Concept" approach. To date, the Company has enrolled more than 25,000 patients in more than 170 trials, delivering speed and cost advantages that set it apart from industry peers.

In addition, BeOne continues to expand its global manufacturing network with its $800 million flagship clinical R&D and manufacturing facility at the Princeton West Innovation Campus in Hopewell, N.J. This state-of-the-art site enables scalable production capacity to support the Company's rapidly growing pipeline, operational resilience, and global ambitions.
