First Quarter 2024 Financial Results

Cash, Cash Equivalents and Investments: As of March 31, 2024, the Company had approximately $1.51 billion in cash, cash equivalents and investments. Cash, cash equivalents and investments declined by approximately $118 million during the first quarter of 2024.

Revenues: Total revenues for the quarter ended March 31, 2024, were $56.4 million compared to $63.0 million for the same period in 2023.

Revenues were comprised of the following components:

• Collaboration revenue: The decrease in collaboration revenue for the first quarter of 2024 compared to the same period in 2023 was driven by the release of profit-sharing amount previously constrained during the three months ended March 31, 2023 and to a lesser extent, lower sales of sotrovimab during the three months ended March 31, 2024, under the Company’s collaboration with GSK.
• Contract revenue: The increase in contract revenue for the first quarter of 2024 compared to the same period in 2023 was primarily driven by the recognition of deferred revenue related to the expiry of GSK’s rights to select up to two additional non-influenza target pathogens during the three months ended March 31, 2024.
• Grant revenue: The decrease in grant revenue was primarily driven by lower revenue related to the Company's agreement with BARDA.

Cost of Revenue: Cost of revenue for the first quarter of 2024 was nominal compared to $1.9 million for the same period in 2023. The decrease was due to lower third-party royalties owed on the sales of sotrovimab.

Research and Development Expenses (R&D): R&D expenses for the first quarter of 2024 were $100.1 million, which included $13.6 million of non-cash stock-based compensation expense, compared to $157.6 million for the same period in 2023, which included $13.4 million of non-cash stock-based compensation expense. The decrease was primarily driven by lower clinical development costs and manufacturing costs associated with VIR-2482.

Selling, General and Administrative Expenses (SG&A): SG&A expenses for the first quarter of 2024 were $36.3 million, which included $10.2 million of non-cash stock-based compensation expense, compared to $46.8 million for the same period in 2023, which included $12.1 million of non-cash stock-based compensation expense. The decrease was primarily driven by cost savings initiatives implemented during the second half of 2023.

Other Income: Other income for the first quarter of 2024 was $15.1 million compared to $0.2 million for the same period in 2023. The increase was primarily due to the decrease in foreign exchange loss related to remeasurement of liability reserved for excess sotrovimab supply and manufacturing capacity and a decrease in loss recognized on the Company's equity investments.

(Provision for) Benefit from Income Taxes: Provision for income taxes for the first quarter of 2024 was $0.3 million compared to benefit from income taxes of $2.2 million for the same period in 2023.

Net Loss: Net loss attributable to Vir for the first quarter of 2024 was $(65.3) million, or $(0.48) per share, basic and diluted, compared to a net loss of $(140.9) million, or $(1.06) per share, basic and diluted for the same period in 2023.

2024 Financial Guidance

The Company reiterates its full year 2024 guidance below, originally provided on February 22, 2024 (in millions):

Approximately three to four percent of the GAAP combined R&D and SG&A expense will be funded by grants. These grants are recognized as revenue.

The GAAP combined R&D and SG&A expense guidance does not include the effect of GAAP adjustments caused by events that may occur subsequent to the publication of this guidance, including, but not limited to, business development activities, litigation, in-process R&D impairments, and changes in the fair value of contingent considerations.
