The gross proceeds to Arsanis from the offering are expected to be $40.0 million, before deducting underwriting discounts and commissions and other offering expenses. In addition, Arsanis has granted the underwriters a 30-day option to purchase up to 600,000 additional shares of common stock from Arsanis at the public offering price, less underwriting discounts and commissions, to cover over-allotments, if any. All of the shares are being offered by Arsanis. Arsanis’ shares are scheduled to begin trading on The NASDAQ Global Market on November 16, 2017 under the ticker symbol “ASNS.”

    The offering is expected to close on November 20, 2017, subject to customary closing conditions.
