SOUTH SAN FRANCISCO, Calif., March 13, 2025 (GLOBE NEWSWIRE) -- Sutro Biopharma, Inc. (Sutro or the Company) (NASDAQ: STRO), an oncology company pioneering site-specific and novel-format antibody drug conjugates (ADCs), today reported its financial results for the full year 2024 and recent business highlights. The Company also announced the completion of a strategic portfolio review resulting in the prioritization of its next-generation ADC pipeline. A conference call will be held today at 2:00 p.m. PT / 5:00 p.m. ET to discuss the pipeline reprioritization, team restructuring and next steps.
Full Year 2024 Financial Highlights
Cash, Cash Equivalents and Marketable Securities
As of December 31, 2024, Sutro had cash, cash equivalents and marketable securities of $316.9 million, as compared to $388.3 million as of September 30, 2024. Cash runway is expected into at least Q4 2026, excluding anticipated milestones from existing collaborations.
Revenue
Revenue was $62.0 million for the year ended December 31, 2024, as compared to $153.7 million for the year ended December 31, 2023, with the 2024 amount related principally to the Astellas collaboration and the Tasly 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.
Operating Expenses
Total operating expenses for the year ended December 31, 2024 were $300.5 million, as compared to $243.0 million for year ended December 31, 2023. The year 2024 includes non-cash expenses for stock-based compensation of $24.7 million and depreciation and amortization of $7.2 million, as compared to $24.9 million and $6.8 million, respectively, in the year 2023. Total operating expenses for the year ended December 31, 2024 were comprised of research and development expenses of $252.0 million and general and administrative expenses of $48.5 million.
Restructuring Expenditures
Cash payments resulting from the strategic portfolio review and related restructuring are estimated to be $40 to $45 million. Cost reductions subsequently realized from the restructuring, combined with refocused clinical development priorities give the Company an expected cash runway into at least the fourth quarter of 2026, excluding anticipated milestones from existing collaborations.
