Recent Progress and Upcoming Late-Stage Pipeline Milestones

Respiratory vaccines:

• Seasonal flu vaccine: In October 2025, Moderna presented Phase 3 efficacy and safety data for its seasonal flu vaccine (mRNA-1010) at IDWeek 2025, and Phase 3 relative vaccine efficacy in a high-risk subset of patients at The European Scientific Working Group on Influenza (ESWI) Conference 2025. The Company expects to complete submissions for approval of mRNA-1010 in the U.S., Canada, Australia and Europe by January 2026.
• Seasonal flu + COVID vaccine: The Company presented Phase 3 immunogenicity subanalyses for its flu/COVID combination vaccine (mRNA-1083) for adults aged 50 years and older at ESWI 2025. The Company expects to refile with Health Canada in 2025 and is awaiting further guidance from U.S. FDA on refiling. Currently, the Company's mRNA-1083 filing is under review with the European Medicines Agency (EMA).

Latent and other vaccines:

• Norovirus vaccine: Moderna's ongoing Phase 3 safety and efficacy study of its trivalent vaccine against norovirus (mRNA-1403) has not accrued sufficient cases and will now enroll a second Northern Hemisphere season (2025-2026) for additional case accruals. The timing of the Phase 3 readout will continue to be dependent on case accruals.
• Cytomegalovirus (CMV) vaccine: After announcing that the Phase 3 study of mRNA-1647 did not meet its primary efficacy endpoint, Moderna is discontinuing development of its congenital CMV program. The Company will continue to evaluate mRNA-1647 in an ongoing Phase 2 trial of bone marrow transplant patients.
