Notes to Unaudited Interim Condensed Financial Statements
1. Organization and Principal Activities
Description of Business
Sutro Biopharma, Inc. (the “Company”) is a clinical stage drug discovery, development and manufacturing company focused on leveraging its integrated cell-free protein synthesis and site-specific conjugation platform, XpressCF+™, to create a broad variety of optimally designed, next-generation protein therapeutics for cancer and autoimmune disorders. The Company was incorporated on April 21, 2003 and is headquartered in South San Francisco, California.
The Company operates in one business segment, the development of biopharmaceutical products.
Liquidity
The Company has incurred significant losses and has negative cash flows from operations. As of September 30, 2019, there was an accumulated deficit of $181.0 million. Management expects to continue to incur additional substantial losses in the foreseeable future as a result of the Company’s research and development activities and costs to operate as a public company.
As of September 30, 2019, the Company had unrestricted cash, cash equivalents and marketable securities of $150.4 million, which are available to fund future operations. The Company will need to raise additional capital to support the completion of its research and development activities and its operations.
The Company believes that its unrestricted cash, cash equivalents and marketable securities as of September 30, 2019 will be sufficient for the Company to continue as a going concern for at least one year from the issuance date of its unaudited interim condensed financial statements.
2. Summary of Significant Accounting Policies
Basis of Presentation and Use of Estimates
The accompanying interim condensed financial statements of the Company are unaudited. These interim condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The December 31, 2018 condensed balance sheet was derived from the audited financial statements as of that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company bases its estimates on historical experience and market-specific or other relevant assumptions that it believes are reasonable under the circumstances. The amounts of assets and liabilities reported in the Company’s balance sheets and the amount of expenses and income reported for each of the periods presented are affected by estimates and assumptions, which are used for, but are not limited to, determining research and development periods under multiple element arrangements, stock-based compensation expense, fair value of redeemable convertible preferred stock warrant liabilities (prior to closing of the Company’s IPO), income taxes and certain accrued liabilities. Actual results could differ from such estimates or assumptions.
The accompanying unaudited interim condensed financial statements have been prepared on the same basis as the audited financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company's financial position, results of operations, comprehensive income (loss), and cash flows for the interim periods. The interim results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019, or for any other future annual or interim period.
The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company's audited financial statements included in the Annual Report on Form 10-K pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, for the year ended December 31, 2018.

Adoption of New Accounting Principles
Revenue Recognition
On January 1, 2019, the Company adopted Accounting Standards Update (ASU) No. 2014-09 (Topic 606), Revenue from Contracts with Customers (“ASC 606”). ASC 606 supersedes the guidance in ASC 605, Revenue Recognition. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.
Upon adoption of ASC 606, the Company used the practical expedients to analyze only those contracts that were still active contracts as of January 1, 2019 and evaluated those contracts based on the cumulative contract modifications through that date. The Company does not believe that the use of the practical expedients has or will have a material impact on its transition adjustment or its prospective accounting. The Company adopted ASC 606 on a modified retrospective basis under which it recognized the cumulative effect of adoption of $10.3 million as a transition adjustment to reduce opening accumulated deficit; therefore, the periods prior to the adoption date of ASC 606 have not been restated. If the Company had continued to use ASC 605 during 2019, revenue would have been $12.7 million and $31.8 million in the three and nine months ended September 30, 2019, respectively, as compared to the $12.3 million and $31.4 million reported in the three and nine months ended September 30, 2019, respectively.
The impact of the adoption of Topic 606 on select unaudited condensed balance sheet as of January 1, 2019 was as follows (in thousands):
