Item 1.01. Entry into a Material Definitive Agreement

On May 11, 2020, Sutro Biopharma, Inc. (“Sutro”) entered into an underwriting agreement (the “Underwriting Agreement”) with Cowen and Company, LLC, Piper Sandler & Co. and Wells Fargo Securities, LLC, as representatives of the several underwriters named therein (the “Underwriters”), pursuant to which Sutro agreed to issue and sell 11,000,000 shares of its common stock (the “Shares”) to the Underwriters (the “Offering”). The Shares will be sold at the public offering price of $7.75 per share. Pursuant to the Underwriting Agreement, Sutro has also granted the Underwriters a 30-day option to purchase up to an additional 1,650,000 shares of its common stock. The Underwriting Agreement contains customary representations and warranties, conditions to closing, market standoff provisions, termination provisions and indemnification obligations, including for liabilities under the Securities Act of 1933, as amended. The Offering is being made pursuant to the shelf registration statement on Form S-3 (File No. 333-234101) that was filed by Sutro with the Securities and Exchange Commission (“SEC”) on October 4, 2019, and declared effective by the SEC on October 11, 2019, and a related prospectus supplement.

Sutro estimates that net proceeds from the Offering will be approximately $79.7 million, after deducting underwriting discounts and commissions and estimated Offering expenses, and assuming no exercise of the Underwriters’ option to purchase additional shares. Sutro intends to use the net proceeds from the Offering, together with its existing cash, cash equivalents and marketable securities, to fund the continued clinical development of STRO-001 and STRO-002 and the remainder to fund the further development of its technology platform, including manufacturing, to broaden its pipeline of product candidates and for working capital and general corporate purposes. Sutro expects the Offering to close on May 14, 2020, subject to the satisfaction of customary closing conditions.

The Underwriting Agreement is filed as Exhibit 1.1 to this report and the foregoing description of the terms of the Underwriting Agreement is qualified in its entirety by reference to such exhibit. A copy of the opinion of Fenwick & West LLP, relating to the validity of the Shares in connection with the Offering, is filed with this Current Report on Form 8-K as Exhibit 5.1.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and other federal securities laws. Any statements contained herein that do not describe historical facts, including, but not limited to, statements regarding the expected net proceeds of the Offering and the anticipated use of proceeds of the Offering, are forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those discussed in such forward-looking statements. Such risks and uncertainties include, among others, the risks identified in Sutro’s filings with the SEC, including its Quarterly Report on Form 10-Q for the three months ended March 31, 2020, filed with the SEC on May 11, 2020, the prospectus supplement related to the Offering, and subsequent filings with the SEC. Any of these risks and uncertainties could materially and adversely affect Sutro’s results of operations, which would, in turn, have a significant and adverse impact on Sutro’s stock price. Sutro cautions you not to place undue reliance on any forward-looking statements, which speak only as of the date they are made. Sutro undertakes no obligation to update publicly any forward-looking statements to reflect new information, events or circumstances after the date they were made or to reflect the occurrence of unanticipated events.
