CAMBRIDGE, Mass.—(BUSINESS WIRE)—November 4, 2021— Moderna, Inc. (Nasdaq: MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today reported financial results and provided business updates for the third quarter of fiscal year 2021.

“We are humbled to have helped hundreds of millions of people around the world with our COVID-19 vaccine and yet we know our work is not done. We will not rest until our vaccine is available to anyone who needs it, and we are working hard to ensure our vaccine is available in low-income countries with approximately 10% of our 2021 volume and significantly more of our 2022 volume going to low-income countries. It is promising to see the real-world evidence showing that the Moderna COVID-19 vaccine shows sustainably high, durable efficacy,” said Stéphane Bancel, Chief Executive Officer of Moderna. “Looking ahead, we are focused on advancing the many other programs in our pipeline. We recently dosed the first participants in the Phase 3 study of our CMV vaccine. CMV is a latent virus that remains in the body for life after infection and can lead to lifelong medical conditions. We are also focused on addressing respiratory viruses in addition to COVID-19, including seasonal flu and RSV. We look forward to sharing data from the Phase 1 study of our flu vaccine candidate soon and we are preparing to start our Phase 2 study. We are also preparing to start the Phase 2/3 study of our RSV vaccine candidate. RSV causes hospitalizations and deaths in our most vulnerable populations of young children and older adults. In addition, we continue to progress our therapeutics pipeline and we look forward to clinical proof of concept data. I would like to thank the Moderna team for their scientific passion and commitment to our mission. I am more energized than ever by the impact our mRNA platform will have on human health.”

• Addressing Variants of Concern: Moderna has four development candidates against SARS-CoV-2 variants of concern, including three which have been administered in a Phase 2/3 clinical trial. The Company’s strategy is to develop booster vaccines against current variants of concern and against potential future variants of concern.

• mRNA-1273.351: Variant-specific candidate against the Beta variant

• mRNA-1273.617: Variant-specific candidate against the Delta variant

• mRNA-1273.211: Multivalent candidate combining the Beta-specific variant and mRNA-1273

• mRNA-1273.213: Multivalent candidate combining the Beta-specific and Delta-specific candidates

• Further Clinical Studies of mRNA-1273

• Phase 2/3 “TeenCOVE” study of mRNA-1273 in adolescents: mRNA-1273 is authorized for use in adolescents ages 12 to 17 in the United Kingdom, European Union, Japan, Canada, Switzerland, Taiwan, Saudi Arabia, Australia and the Philippines. The U.S. FDA notified the Company that it will require additional time to complete its assessment of Moderna’s EUA request for the use of mRNA-1273 at the 100 µg dose level in adolescents 12 to 17 years of age.

• Phase 2 “KidCOVE” study of mRNA-1273 in young children: The Phase 2 study of mRNA-1273 in pediatric population ages 6 months to under 12 years is ongoing. Moderna is sharing new data from the KidCOVE study of mRNA-1273 in children ages 6 years to under 12 years. Vaccine efficacy of 100% using the P301 primary case definition for COVID-19 was observed two weeks after the first dose of mRNA-1273 at the 50 µg dose level. Additionally, for asymptomatic infection two weeks after the first dose, vaccine efficacy was 65% (95% CI: .16, .85). For SARS-CoV-2 infection regardless of symptoms, vaccine efficacy was 80% (95% CI: .62, .90) two weeks after the first dose. On October 24, the Company announced positive top line top line data from the Phase 2/3 study of mRNA-1273 in children 6

to under 12 years of age. Geometric mean ratio (GMR) comparing the response in children to the response in young adults from the Phase 3 COVE study was 1.5 (95% CI: 1.3, 1.8), with a seroresponse rate of 99.3%. Two 50 µg doses of mRNA-1273 were generally well tolerated. Moderna plans to submit results to the EMA and regulatory agencies around the world soon. Dose selection studies are underway for the 2 to under 6 years and 6 months to under 2 years age groups.

• Phase 3 “COVE Transplant” study of mRNA-1273: The Phase 3 study of mRNA-1273 in adults with a kidney or liver transplant is ongoing, including the offer of a third vaccine dose to these immunocompromised participants.

• Next-generation vaccine candidate against COVID-19 (mRNA-1283): The Phase 1 study of mRNA-1283 is fully enrolled and ongoing. An interim analysis of data from the Phase 1 study of mRNA-1283 at three dose levels indicate that a lower dose of mRNA-1283 achieved similar neutralizing antibody responses compared to a primary series of mRNA-1273. mRNA-1283 had an acceptable tolerability profile. The Company expects to start a Phase 2 booster study in the near term. mRNA-1283 is a next-generation vaccine candidate against COVID-19 that encodes for the portions of the SARS-CoV-2 spike protein critical for neutralization, specifically the Receptor Binding Domain (RBD) and N-terminal Domain (NTD). The encoded mRNA-1283 antigen is shorter than mRNA-1273 and is being developed as a potential refrigerator-stable mRNA vaccine that will facilitate easier distribution and administration by healthcare providers.

Additional vaccines against acute respiratory infections

• Seasonal influenza vaccine (mRNA-1010): The Phase 1 study evaluating the safety and reactogenicity of three different dose levels of mRNA-1010 in adults over age 18 is fully enrolled (N=180). mRNA-1010 encodes for hemagglutinin (HA) glycoproteins of four flu strains and targets lineages recommended by the WHO for the prevention of influenza, including seasonal influenza A H1N1, H3N2 and influenza B Yamagata and Victoria.

• COVID-19 and flu combination vaccine (mRNA-1073): mRNA-1073 encodes for the COVID-19 spike protein and the Flu HA glycoproteins. Moderna owns worldwide commercial rights to mRNA-1073.

• Respiratory syncytial virus (RSV) vaccine (mRNA-1345): At its annual R&D Day on September 9, the Company shared positive Phase 1 interim data from the older adult cohort. Moderna is preparing for a Phase 2/3 study of RSV in older adults (ages older than 60 years) and expects to begin this study by the end of 2021. The Company expects this Phase 2/3 study will be a global study conducted in locations influenced by the epidemiology of RSV and expects to enroll approximately 34,000 participants, subject to agreement with regulatory authorities. The FDA has granted Fast Track designation for mRNA-1345 in adults older than 60 years of age. RSV is the leading cause of severe respiratory illness in young children and older adults (65+). The Phase 1 study of mRNA-1345 to evaluate the tolerability and reactogenicity of mRNA-1345 in younger adults, women of child-bearing potential, older adults and seropositive toddlers is ongoing. All four cohorts of younger adults (ages 18-49 years) and all four cohorts of older adults (ages 65-79 years) are fully enrolled. There is no approved vaccine to prevent RSV. Moderna owns worldwide commercial rights to mRNA-1345.

• Human metapneumovirus (hMPV) and parainfluenza type 3 (PIV3) vaccine (mRNA-1653): Moderna is enrolling seropositive pediatric participants (12-36 months of age) in the Phase 1 study of hMPV/PIV3 study (mRNA-1653). The first cohort in this study is fully enrolled. Moderna owns worldwide commercial rights to mRNA-1653.

• Pediatric RSV and hMPV combination vaccine (mRNA-1365): mRNA-1365 encodes for the RSV prefusion F glycoprotein and the hMPV F protein. Moderna owns worldwide commercial rights to mRNA-1365.

Vaccines against latent viruses

• Cytomegalovirus (CMV) vaccine (mRNA-1647): The first participants have been dosed in the Phase 3 study, known as CMVictory, which is evaluating the safety and efficacy of mRNA-1647 against primary CMV infection in women ages 16-40 years. The Company will seek to enroll up to approximately 8,000 participants in the study, including 6,900 women of child-bearing potential, at approximately 150 sites globally, beginning in the U.S. Moderna has set a goal of enrolling a diverse group of U.S. participants into the study, including approximately 42% of participants who are Persons of Color. Based on the interim analysis of the Phase 2 study, the 100 µg dose has been chosen for the Phase 3 pivotal study. The ClinicalTrials.gov identifier is NCT05085366. To learn more about eligibility, visit www.CMVictory.com. Moderna owns worldwide commercial rights for mRNA-1647.

• Epstein-Barr virus (EBV) vaccine (mRNA-1189): The Phase 1 study of mRNA-1189 is expected to begin soon. EBV is a member of the herpesvirus family and is spread through bodily fluids (e.g., saliva) and contracted primarily by young children and adolescents. It is a major cause of infectious mononucleosis (IM), and associated risks to other long-term medical conditions, including an increased risk of developing multiple sclerosis by approximately 4 to 10-fold, certain lymphoproliferative disorders and cancers, and autoimmune diseases^3,4. While EBV infection in early childhood is predominantly asymptomatic, primary infection in adolescence can lead to IM, which can debilitate patients for weeks to months, sometimes requiring hospitalization for serious complications. mRNA-1189 is a vaccine being developed to prevent IM, and potentially EBV infection. Similar to Moderna’s CMV vaccine (mRNA-1647), mRNA-1189 contains four mRNAs that encode EBV envelope glycoproteins (gH, gL, gp42, gp220). There is currently no approved vaccine for EBV or IM. Moderna owns worldwide commercial rights to mRNA-1189.

• Epstein-Barr virus (EBV) therapeutic vaccine candidate (mRNA-1195): mRNA-1195 is being developed to prevent longer term sequelae of EBV infection, which are associated with loss of immune control of EBV latent infection, creating longer-term complications. mRNA-1195 is in pre-clinical development and encodes for additional antigens than mRNA-1189. The Company expects to initially test the vaccine in post-transplant lymphoproliferative disorder (PTLD) because at least 80% of PTLD in transplant patients is associated with EBV. The Company expects to also pursue other longer-term potential indications for this vaccine, including multiple sclerosis.

• HIV vaccine (mRNA-1644 & mRNA-1574): HIV is the virus responsible for acquired immunodeficiency syndrome (AIDS), a lifelong, progressive illness with no effective cure. Approximately 38 million people worldwide are currently living with HIV with 1.2 million in the U.S. Approximately 2 million new infections of HIV are acquired worldwide every year and approximately 690,000 people die annually due to complications from HIV/AIDS. mRNA-1644, a collaboration with the International AIDS Vaccine Initiative (IAVI) and the Bill and Melinda Gates Foundation, is a novel approach to HIV vaccine strategy in humans designed to elicit broadly neutralizing HIV-1 antibodies (bNAbs). A Phase 1 study for mRNA-1644 will use iterative human testing to validate the approach and antigens and multiple novel antigens will be used for germline-targeting and immuno-focusing. A second approach, mRNA-1574, is being evaluated in collaboration with the NIH and includes multiple native-like trimer antigens. The Company expects to begin Phase 1 studies for both mRNA-1644 and mRNA-1574 in 2021.

Third Quarter 2021 Financial Results

• Revenue: Total revenue was $5.0 billion for the three months ended September 30, 2021, compared to $157 million for the same period in 2020. Total revenue was $11.3 billion for the nine months ended September 30, 2021, compared to $232 million for the same period in 2020. Total revenue increased in 2021 as a result of commercial sales of the Company’s COVID-19 vaccine, and to a lesser extent, grant revenue. Product sales for the three and nine months ended September 30, 2021 were $4.8 billion and $10.7 billion, respectively, from sales of 208 million and 510 million doses of the Company’s COVID-19 vaccine for the three and nine months ended September 30, 2021, respectively. The increase in grant revenue of $286 million for the nine months ended September 30, 2021 was primarily driven by an increase in revenue from BARDA related to the Company’s COVID-19 vaccine development. Grant revenue for the three months ended September 30, 2021 was relatively flat compared to the same period in 2020.

• Cost of Sales: Cost of sales was $722 million, or 15%, of product sales for the three months ended September 30, 2021, including third-party royalties of $168 million. Cost of sales was $1.7 billion, or 16%, of the Company’s product sales, for the nine months ended September 30, 2021, including third-party royalties of $400 million. A portion of the inventory costs associated with the Company’s product sales for the nine months ended September 30, 2021 was expensed as pre-launch inventory costs in 2020. At the end of the first quarter of 2021, the Company’s zero-cost COVID-19 vaccine inventory was substantially utilized. If inventory sold for the nine months ended September 30, 2021 was valued at cost, the Company’s cost of sales for the period would have been $1.9 billion, or 17% of product sales.

• Research and Development Expenses: Research and development expenses were $521 million for the three months ended September 30, 2021, compared to $344 million for the same period in 2020. Research and development expenses were $1.3 billion for the nine months ended September 30, 2021, compared to $611 million for the same period in 2020. The growth in spending in 2021 was mainly due to increases in clinical trial expenses and personnel-related costs, largely driven by increased mRNA-1273 clinical development and headcount.

• Selling, General and Administrative Expenses: Selling, general and administrative expenses were $168 million for the three months ended September 30, 2021, compared to $48 million for the same period in 2020. Selling, general and administrative expenses were $366 million for the nine months ended September 30, 2021, compared to $109 million for the same period in 2020. The growth in spending in 2021 was mainly due to increases in consulting and outside services, personnel-related costs, marketing expenses and distributor fees, primarily attributable to the Company’s COVID-19 vaccine commercialization-related activities and increased headcount.

• Net Income (Loss): Net income was $3.3 billion for the three months ended September 30, 2021, compared to a net loss of $(233) million for the same period in 2020. Net income was $7.3 billion for the nine months ended September 30, 2021, compared to a net loss of $(474) million for the same period in 2020.

• Cash Position: Cash, cash equivalents and investments as of September 30, 2021 and December 31, 2020 were $15.3 billion and $5.2 billion, respectively.

• Net Cash Provided By Operating Activities: Net cash provided by operating activities was $10.3 billion for the nine months ended September 30, 2021, compared to $763 million for the same period in 2020. Net cash provided by operating activities increased significantly in 2021, mainly due to net income of $7.3 billion and additional customer deposits received during the period for the Company’s future COVID-19 vaccine supply.

• Cash Used for Purchases of Property and Equipment: Cash used for purchases of property and equipment was $164 million for the nine months ended September 30, 2021, compared to $44 million for the same period in 2020.

2021 Updated Financial Framework

• For Expected Delivery in Fiscal Year (FY) 2021: Expected to realize product sales for FY 2021 between $15 billion and $18 billion.

9

• Key Variables Impacting FY 2021 Revenues: Fewer doses for delivery in 2021, shifted to early 2022; prioritization of deliveries to low-income countries through COVAX and African Union

• Vaccine Dose Deliveries for FY 2021: The Company expects deliveries of its COVID-19 vaccine in FY 2021 to be between 700 million and 800 million doses at the 100 µg dose level. Key variables impacting output include longer delivery lead times for international shipments and exports that may shift deliveries to early 2022, temporary impact from expansion of fill/finish capacity and ramp up of product release to market.

• Cost of Sales: Cost of sales as percentage of product sales are expected to be between 16-17% for FY 2021.

• 2021 Research & Development (R&D) and Selling, General & Administrative (SG&A) Expenses: Continue to expect quarter over quarter cost increases in R&D and SG&A expenses during 2021 as commercial and research and development activities and expenses ramp up.

• Tax Rate: The Company now expects the effective tax rate for 2021 to be in the high single digit range as a result of the forecasted global sales mix and utilization of the accumulated net operating loss carry-forward of $2.3 billion.

• Capital Expenditures: Expect approximately $0.4 billion of capital investments for 2021.

• Share Repurchase Program: The Board of Directors has authorized a share repurchase program of up to $1 billion over a two-year period to return excess capital to shareholders. No shares were repurchased through the end of the third quarter.

2022 Revenue Drivers

We expect several dynamics will drive 2022 revenues:

• APAs Signed: The Company has signed approximately $17 billion of advance purchase agreements (APAs) for delivery in 2022.

• APAs with Options: The Company anticipates the exercise of options under 2022 APAs of up to $3 billion.

• U.S. Fall 2022 Booster Market: Subject to receipt of a BLA or sBLA for boosters prior to the fall booster season, the Company anticipates commercial booster market sales could be up to $2 billion.

Based on these three revenue drivers, the Company believes 2022 sales could be in the range of $17 billion to $22 billion. The Company continues to have discussions for 2022 APAs with governments and international organizations, including COVAX, the Pan American Health Organization (PAHO) and the African Union.

As per the advance purchase agreement signed on behalf of the COVAX Facility, Gavi continues to retain the option to procure 233 million additional doses in 2022 for a potential total of 500 million doses between 2021 and 2022 under the agreement. All doses are offered at Moderna’s lowest tiered price, in line with the Company’s global access commitments.
