Pursuant to that certain Controlled Equity OfferingSM Sales Agreement, dated December 3, 2018 (the “Sales Agreement”), that Spero Therapeutics, Inc.

(“Cantor”), the Company may offer and sell, from time to time, shares of its common stock through Cantor, acting as agent, through an “at the market offering” as defined in Rule 451(a)(4) (the “ATM Offering”), promulgated under the Securities Act of 1933, as amended. On December 3, 2018, the Company filed a prospectus supplement (the “ATM Prospectus Supplement”) pursuant to which it may offer and sell, from time to time, shares of its common stock having an aggregate offering price of up to $50,000,000 through Cantor under the Sales Agreement. As of the date of this report, the Company has sold $15,419,270.41 of shares of common stock under the ATM Offering. Effective as of the date of this report, the Company has terminated the ATM Prospectus Supplement, but the Sales Agreement remains in full force and effect.
