SOUTH SAN FRANCISCO, Calif., March 25, 2024 – Sutro Biopharma, Inc. (Sutro or the Company) (NASDAQ: STRO), a clinical-stage oncology company pioneering site-specific and novel-format antibody drug conjugates (ADCs), today reported its financial results for the full year 2023, its recent business highlights, and a preview of select anticipated milestones.
“The year 2023 was pivotal for Sutro, with the initiation of REFRαME-O1, our registration-directed study of luvelta for platinum-resistant ovarian cancer (PROC) patients, further validating our next-generation ADC capabilities. In addition, we advanced our earlier stage programs, strengthened our management team, and bolstered our already strong cash position with additional non-dilutive capital,” said Bill Newell, Sutro’s Chief Executive Officer. “We look forward to continuing the momentum in 2024, with the initiation of a second registration-directed trial with luvelta, REFRαME-P1, for pediatric patients with CBF/GLIS AML, and two additional planned INDs. I am delighted with the strides we are taking towards meaningfully impacting the lives of cancer patients in need.”

Full Year 2023 Financial Highlights
Cash, Cash Equivalents and Marketable Securities
As of December 31, 2023, Sutro had cash, cash equivalents and marketable securities of $333.7 million, as compared to $321.1 million as of September 30, 2023, and approximately 0.7 million shares of Vaxcyte common stock with a fair value of $41.9 million, which together provide a projected cash runway into the second half of 2025, based on current business plans and assumptions. Current market conditions provide a challenging financing environment. In this context, Sutro is continuing its process of evaluating its programs and spending.
Unrealized Gain from Increase in Value of Vaxcyte Common Stock
The non-operating, unrealized gain of $9.9 million for the year 2023 was due to the increase since December 31, 2022 in the estimated fair value of Sutro’s holdings 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 $153.7 million for the year ended December 31, 2023, as compared to $67.8 million for the same period in 2022, with the 2023 amount related principally to the Vaxcyte manufacturing rights agreement option exercise, Astellas and Merck collaborations, and the recognition of a contingent payment from Tasly. 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, 2023 were $243.0 million, as compared to $196.7 million for the same period in 2022. The year 2023 includes non-cash expenses for stock-based

compensation of $24.9 million and depreciation and amortization of $6.8 million, as compared to $26.3 million and $5.7 million, respectively, in the comparable 2022 period.
