Full Year 2018 Financial Highlights
Cash, Cash Equivalents and Marketable Securities
As of December 31, 2018, Sutro had cash, cash equivalents and marketable securities of $204.5 million.
Revenue was $38.4 million for the year ended December 31, 2018, which included collaboration revenue of $32.4 million recognized primarily from Celgene, Merck andEMD Serono, in addition to other revenue of $6.0 million. During the third and fourth quarters of 2018, Sutro began recording revenue from Merck, primarily from the $60.0 million upfront payment received by Sutro under the July 2018 collaboration and licensing agreement, which revenue will be recognized over multiple years. Future collaboration revenue from Celgene, Merck and EMD Serono, and from any future collaboration partners, will fluctuate as a result of the amount and timing of revenue recognition of upfront, milestones and other collaboration agreement payments.
Total operating expenses for the year ended December 31, 2018, were $75.6 million compared with $71.0 million for the same period in 2017, including non-cash stock-based compensation of $2.9 million and $1.4 million, and depreciation and amortization expense of $4.5 million and $5.0 million, in the year 2018 and 2017, respectively. Total operating expenses for the year 2018 were comprised of research and development expenses of $54.3 million and general and administrative expenses of $21.4 million, with both expense types expected to increase in 2019 as Sutro’s internal product candidates advance in clinical development and additional general and administrative expenses are incurred as a public company following its IPO that closed on October 1, 2018.
Net Loss Per Share Calculation
Sutro financial statements following September 30, 2018, including share and per share amounts, give effect to common stock shares issued in the IPO and the Merck concurrent private placement, and common stock from the conversions of Sutro’s previously outstanding redeemable convertible preferred stock, as these transactions were completed on October 1, 2018.
