Unrealized Gain from Increase in Value of Vaxcyte Common Stock

Vaxcyte common stock held by Sutro will be remeasured at fair value based on the closing price of Vaxcyte’s common stock on the last trading day of each reporting period, with any non-operating, unrealized gains and losses recorded in Sutro’s statements of operations.
Revenue
Revenue was $25.7 million for the quarter ended June 30, 2024, as compared to $10.4 million for the same period in 2023, with the 2024 amount related principally to the Astellas collaboration and the Vaxcyte agreement. Future collaboration and license revenue under existing agreements, and from any additional collaboration and license partners, will fluctuate as a result of the amount and timing of revenue recognition of upfront, milestones, and other agreement payments.
