SOUTH SAN FRANCISCO, Calif., November 13, 2023 – 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 third quarter of 2023, its recent business highlights, and a preview of select anticipated milestones.
“The last few months have been productive for Sutro, with the recent presentation of encouraging early data for luvelta in endometrial cancer, as well as the appointment of Dr. Hans-Peter Gerber as our CSO. Dr. Gerber’s extensive experience in discovering and developing novel ADCs further strengthens our position as a scientific leader in this important therapeutic modality,” said Bill Newell, Sutro’s Chief Executive Officer. “The recent encouraging update with luvelta in endometrial cancer gave us further confidence in the potential for luvelta to be a targeted treatment for a range of indications with significant unmet need. Additionally, we are pleased with the pace of enrollment of our Phase 2/3 trial for luvelta in patients with platinum resistant ovarian cancer, REFRaME-O1.”
“Sutro’s remarkable platform has the potential to yield best in class product candidates from all of our ADC design concepts – including ADCs, iADCs, and ADC2. The diversity of product candidate attributes enabled by Sutro technology is what originally attracted me to the company,” said Hans-Peter Gerber, Sutro’s CSO. “After an in-depth review of the platform and programs developed at Sutro, I am excited to combine our industry leading technology with our established development capabilities to deliver fit-for-purpose molecules that could transform the lives of cancer patients with limited options.”

Third Quarter 2023 Financial Highlights
Cash, Cash Equivalents and Marketable Securities
As of September 30, 2023, Sutro had cash, cash equivalents and marketable securities of $321.1 million, as compared to $358.3 million as of June 30, 2023, and approximately 0.7 million shares of Vaxcyte common stock with a fair value of $34.0 million, which together provide a projected cash runway into the first half of 2025, based on current business plans and assumptions. Current market conditions provide a challenging financing environment. In this context, Sutro is evaluating its programs and spending as it fully develops its 2024 goals and financial plan.
Unrealized Gain from Increase in Value of Vaxcyte Common Stock
The non-operating, unrealized gain of $0.7 million in the quarter ended September 30, 2023 was due to the increase since June 30, 2023 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 $16.9 million for the quarter ended September 30, 2023, as compared to $25.1 million for the same period in 2022, with the 2023 amount related principally to the Astellas collaboration 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 quarter ended September 30, 2023 were $60.9 million, as compared to $46.4 million for the same period in 2022. The third quarter of 2023 includes non-cash expenses for stock-based compensation of $6.0 million and depreciation and amortization of $1.7 million, as compared to $6.8 million and $1.4 million, respectively, in the comparable 2022 period. Total operating expenses for the quarter ended September 30, 2023 were comprised of research and development expenses of $45.7 million and general and administrative expenses of $15.3 million.
Royalty Monetization Agreement
As related to the royalty monetization agreement between Sutro and an affiliate of Blackstone Life Sciences, Sutro received in June 2023 a $140.0 million upfront payment and is eligible to receive up to an additional $250.0 million in future milestone payments. Sutro recorded the $140.0 million upfront payment from Blackstone as a deferred royalty obligation related to the sale of future royalties on the Company’s condensed Balance Sheets as of June 30, 2023. Due to the Company’s ongoing manufacturing obligations, the Company accounted for the proceeds as imputed debt and will recognize future non-cash royalty revenues. Non-cash interest expense will be recognized over the estimated life of the royalty term arrangement using the effective interest method based on the imputed interest rate derived from estimated amounts and timing of future royalty payments to be received from Vaxcyte. As part of the sale, Sutro incurred approximately $3.8 million in transaction costs, which are being amortized over the estimated life of the royalty term arrangement using the effective interest method. As future royalties are earned from Vaxcyte by Blackstone, the balance of the deferred royalty obligation will be amortized over the estimated life of the royalty term arrangement.
