Vir COVID-19 antibody program Role of antibodies in the context of vaccines and convalescent plasma • We believe the medical need for VIR-7831 will continue to be significant Clinical trial design and execution is critical • We believe both the endpoint and the population selected matter • We believe we may achieve our primary endpoint by January 2021 Not all neutralizing antibodies are created equal • We believe VIR-7831 is differentiated by its high barrier to resistance, potent effector function, and potential for increased increase lung tissue concentration and extended half-life © 2020 Vir Biotechnology, Inc.

Medical need example: antibodies for treatment 35,000 COVID-19 cases a day in USA: up to ~13 million cases a year In the absence of herd immunity, a hypothetical vaccine that is 70% efficacious, with 50% of the population vaccinated: up to ~65% of cases might remain Even with such a hypothetical vaccine, there could be up to ~8.5 million Americans in need of treatment each year We believe there will be a continued need for antibodies as treatment https://covid.cdc.gov/covid-data-tracker/#cases: Sept 9, 2020 1:16PM, 262,971 cases in last 7 days https://www.cdc.gov/mmwr/volumes/69/wr/mm6924e2.htm © 2020 Vir Biotechnology, Inc. 6

Medical need example: antibodies for prophylaxis Numerous examples of vaccines performing worse in the elderly compared to the broader population (e.g. Flu, HBV) Even if vaccinated, anyone over the age of 75 is potentially high-risk and therefore a potential candidate for mAb prophylaxis • The reported risk of hospitalization in age ³ 75 is >8x higher than young adults • The reported overall risk of death in age ³ 75 is >220x higher than young adults The potential need for antibodies as prophylaxis is enormous: • Approximately 20M adults in US are age ³ 75 • Potentially many other high-risk groups, in addition to age ³ 75 pubmed.ncbi.nlm.nih.gov/30501873/ www.census.gov/prod/cen2010/briefs/c2010br-09.pdf © 2020 Vir Biotechnology, Inc. 7 www.cdc.gov/coronavirus/2019-ncov/covid-data/investigations-discovery/hospitalization-death-by-age.html

Limitations of convalescent plasma No clear benefit based on a randomized clinical trial Inconsistent potency: titer can range from 1:10 to 1:10,000 Limited to hospitalized use Cannot be mass produced Based on in vitro neutralization estimates, we believe VIR-7831 has the potential to be at least 300x more potent than convalescent plasma © 2020 Vir Biotechnology, Inc.

Our perspective on the competitive landscape It matters when one finishes, not when one starts . . . . . . it only matters when one finishes, if one meets one’s primary endpoint . . . meeting the primary endpoint only matters if it leads to approval Competitor A example: • Multiple and ongoing changes to study size, and delays to study completion dates • New Phase I study for adverse event of special interest • Endpoint: “Proportion of patients with at least one Covid-19 related medically attended visit” Competitor B example: • Initial study is a Phase 2, not a Phase 3 • Endpoint: “Change from baseline to day 11 in SARS-CoV-2 viral load” www.clinicaltrials.gov © 2020 Vir Biotechnology, Inc.
