Adalimumab biosimilar(Alvotech)

Enhanced process increases manufacturing productivity and frees up capacity to support growing demand across Alvotech’s biosimilars portfolio REYKJAVIK, Iceland and LONDON, UK (October 20, 2026) - Alvotech (NASDAQ: ALVO; ALVO-SDB), a global biotechnology company specializing in the development and manufacture of biosimilar medicines for patients worldwide, today announced that the U.S. Food and Drug Administration (FDA) has approved a new manufacturing process for SIMLANDI® (adalimumab-ryvk), Alvotech’s biosimilar to Humira® (adalimumab). The FDA approval allows Alvotech to introduce Process 2.0 for the manufacture of adalimumab drug substance in its DSM2 manufacturing suite in Reykjavik, Iceland. The new process more than doubles drug substance output per batch without changing the upstream manufacturing scale. The improvement was achieved through targeted process development, effective process transfer and successful process validation, with demonstrated comparability to the previously approved process, maintaining product quality, safety and efficacy. “More than doubling drug substance output per batch while maintaining product quality is a significant achievement that reflects the expertise of our process development and manufacturing teams,” said Joseph McClellan, Chief Operating Officer of Alvotech. “The new process allows us to manufacture the same quantity of drug substance in fewer batches, freeing up capacity to support other products in our portfolio, making better use of our existing infrastructure and giving us greater flexibility to respond to growing demand. Together with the recent FDA approval of additional manufacturing capacity, this demonstrates the strength of our operations in Reykjavik and reinforces our ability to deliver reliable supply to our commercial partners as demand for our biosimilars continues to grow.” For further information, contact: Media Benedikt Stefansson Sarah MacLeod alvotech.media@alvotech.com Investors Dr. Balaji V Prasad Benedikt Stefansson Mikaela Vilchez alvotech.ir@alvotech.com About Alvotech Alvotech is a biotechnology company, founded by Robert Wessman, focused solely on the development and manufacture of biosimilar medicines for patients worldwide.

AVT29 submitted to the European Medicines Agency as a line extension to the existing marketing authorization for Mynzepli® (aflibercept 2 mg) High-dose aflibercept offers the potential to reduce treatment frequency for patients with retinal diseases REYKJAVIK, Iceland and LONDON, UK (October 14, 2026) - Alvotech (NASDAQ: ALVO; ALVO-SDB), a global biotechnology company specializing in the development and manufacture of biosimilar medicines for patients worldwide, and Advanz Pharma Holdco Limited (“Advanz Pharma”), a global pharmaceutical company with a strategic focus on specialty, hospital, and rare disease medicines, today announced the submission of a European regulatory application for AVT29, a proposed biosimilar to Eylea® 8 mg (aflibercept 114.3 mg/mL), which is marketed as Eylea HD® in the United States. Based on publicly available information, this marks the first regulatory submission worldwide for a proposed biosimilar to Eylea® 8mg. The application was submitted as a line extension to the existing European marketing authorization for Mynzepli® (AVT06, 2 mg aflibercept, 40 mg/ mL), Alvotech’s biosimilar to Eylea® 2 mg. Eylea® is used to treat certain retinal diseases through injections directly into the eye. According to the approved European product information, the 8mg formulation allows treatment intervals of 16 weeks for certain patients, compared with the standard eight-week maintenance interval for the original 2 mg formulation, potentially reducing the frequency of maintenance injections and reducing the treatment burden for patients [ 2 ] . According to publicly reported financial results, the 8mg formulation accounted for approximately 57% of combined global Eylea® 2mg and 8mg sales by value in the second quarter of 2026, up from approximately 30% in the same period in 2025 [ 3 ] . “To our knowledge, this is the first regulatory submission anywhere in the world for a proposed biosimilar to Eylea 8 mg. This is an important achievement for Alvotech and demonstrates the strength of our in-house development capabilities,” said Lisa Graver, Chief Executive Officer of Alvotech. “We recognized early the potential of high-dose aflibercept and invested in developing both the 2 mg and 8 mg formulations. Building on the European approval of Mynzepli, this milestone positions us at the forefront of the next wave of aflibercept biosimilars and reflects our commitment to broadening access to high-quality biologic medicines.” Steffen Wagner, Chief Executive Officer of Advanz Pharma, said: “This submission represents an important milestone in our partnership with Alvotech and our shared commitment to improving access to high-quality, affordable medicines. Following the European approval of Mynzepli, we are pleased to be advancing a high-dose formulation that could offer additional treatment options for patients and healthcare professionals across Europe.” Mynzepli® received European Commission approval in August 2025 as a biosimilar to Eylea® 2 mg (aflibercept 40 mg/mL), in both vial and prefilled syringe presentations, for the treatment of various retinal diseases. Under the companies’ partnership agreement, Alvotech is responsible for development and commercial supply of AVT06 and AVT29, while Advanz Pharma is responsible for registration and commercialization in Europe. Advanz Pharma holds exclusive commercialization rights in Europe, except in Germany and France, where the rights are semi-exclusive.
