Summary of Financial Updates

2023 financial updates: Moderna achieved 2023 COVID-19 vaccine sales of approximately $6.7 billion (unaudited). This includes approximately $6.1 billion of COVID-19 vaccine sales, and recognition of approximately $0.6 billion of deferred revenue related to the Company's efforts with GAVI, The Vaccine Alliance. Cash, cash equivalents and investments at year-end 2023 were in excess of $13 billion. Full financial details will be reported on the Company's earnings call on February 22, 2024.

2024 - 2026 financial framework: The Company expects its COVID-19 franchise to be profitable in its anticipated sales scenarios for 2024 and beyond. Moderna continues to project approximately $4 billion in product sales in 2024, mostly in the second half of the year, primarily due to COVID-19 vaccine sales and the launch of its RSV vaccine. The Company anticipates returning to organic sales growth in 2025 and expects to break even in 2026 through product launches and disciplined investment.

Summary of Upcoming Late-Stage Pipeline Milestones

Moderna expects numerous product milestones in 2024 and 2025 across its vaccines and therapeutics portfolio.

Respiratory vaccines:

• Respiratory syncytial virus (RSV) vaccine: Moderna has filed for regulatory approvals for its vaccine for the prevention of RSV-associated lower respiratory tract disease (RSV-LRTD) and acute respiratory disease (ARD) in adults ages 60 years or older (mRNA-1345). The Company expects regulatory approvals beginning in the first half of 2024. Moderna will enter the RSV market with a strong competitive profile as the only pre-filled syringe product available at the time of launch, along with robust efficacy data, a well-established safety and tolerability profile, and widespread consumer awareness and demand established in 2023.
• Next-generation COVID-19 vaccine: Moderna's next-generation, refrigerator-stable COVID-19 vaccine (mRNA-1283) is currently in its pivotal Phase 3 study. The Company anticipates data from the study in the first half of 2024.
• Seasonal flu vaccine: Moderna's seasonal flu vaccine (mRNA-1010) demonstrated consistently acceptable safety and tolerability across three Phase 3 trials. In the most recent Phase 3 trial (P303), mRNA-1010 met all immunogenicity endpoints, demonstrating higher titers compared to a currently licensed vaccine. mRNA-1010 has also shown higher or comparable titers compared to a currently licensed enhanced vaccine (Fluzone HD®) in a separate Phase 1/2 study. The Company is in discussions with regulators and intends to file in 2024.
• Seasonal flu + COVID vaccine: Moderna's Phase 3 trial of its combination vaccine against seasonal flu and COVID-19 (mRNA-1083) is fully enrolled. The Company anticipates data from the study in 2024.

Latent and other vaccines:

• Cytomegalovirus (CMV) vaccine: The pivotal Phase 3 study of Moderna's CMV vaccine candidate (mRNA-1647) is fully enrolled and accruing cases, evaluating its efficacy, safety and immunogenicity in the prevention of primary infection in women of childbearing age. The Company anticipates potential efficacy data from the study in 2024.

Oncology therapeutics:

• Individualized Neoantigen Therapy (INT): Moderna continues to demonstrate the potential clinical benefit of its INT program (mRNA-4157). In partnership with Merck, Phase 3 trials continue to enroll in resected high-risk (stage III/IV) melanoma and completely resected stage II, IIIA or IIIB non-small cell lung cancer. Moderna and Merck plan to rapidly expand their clinical studies to additional tumor types in 2024. The Company recently announced results of a three-year analysis of its Phase 2b study evaluating INT in combination with KEYTRUDA®, Merck's anti-PD-1 therapy, in patients with resected high-risk melanoma. Compared to KEYTRUDA alone, this combination continued to show an improvement in recurrence-free survival, reducing the risk of recurrence or death by 49%, as well as in distant metastasis-free survival, reducing the risk of developing distant metastasis or death by 62%.

Rare disease therapeutics:

• Propionic acidemia (PA) & methylmalonic acidemia (MMA): The Company expects to advance its PA (mRNA-3705) and MMA (mRNA-3927) programs into pivotal studies in 2024.
