On August 18, 2020, Delcath Systems, Inc. (the “Company”) entered into a Controlled Equity Offering^SM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor Fitzgerald”), pursuant to which the Company may offer and sell, from time to time, through Cantor Fitzgerald, as sales agent or principal, shares of the Company’s common stock, par value $0.01 per share (the “Placement Shares”), having an aggregate offering price of up to $10.0 million (the “ATM Offering”).

The Company has no obligation to sell any Placement Shares under the Sales Agreement. Subject to the terms and conditions of the Sales Agreement, Cantor Fitzgerald will use commercially reasonable efforts, consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations and the rules of the Nasdaq Stock Market, to sell Placement Shares from time to time based upon the Company’s instructions, including any price, time or size limits specified by the Company. Under the Sales Agreement, Cantor Fitzgerald may sell Placement Shares by any method deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended. The Company will pay Cantor Fitzgerald a commission of 3.0% of the aggregate gross proceeds from each sale of Placement Shares, reimburse Cantor Fitzgerald’s legal fees and disbursements up to $50,000 and provide Cantor Fitzgerald with customary indemnification and contribution rights. The Sales Agreement may be terminated by Cantor Fitzgerald or the Company upon notice to the other party as provided in the Sales Agreement, or by Cantor Fitzgerald at any time in certain circumstances, including the occurrence of a material and adverse change in the Company’s business or financial condition that makes it impractical or inadvisable to market the Placement Shares or to enforce contracts for the sale of the Placement Shares.

The issuance and sale, if any, of the Placement Shares by the Company under the Sales Agreement will be made pursuant to the Company’s effective “shelf” registration statement on Form S-3 (Registration Statement No. 333-227970) (the “Registration Statement”), the base prospectus contained therein, dated December 21, 2018, and a prospectus supplement relating to the ATM offering, dated August 18, 2020.

The Sales Agreement is attached to this Current Report on Form 8-K as Exhibit 1.1 and is incorporated herein by reference. The foregoing description of the material terms of the Sales Agreement does not purport to be complete and is qualified in its entirety by reference to the exhibit attached hereto.

A copy of the opinion of McCarter & English, LLP, relating to the legality of the Placement Shares, is filed as Exhibit 5.1 to this Current Report on Form 8-K and is hereby incorporated by reference into the Registration Statement.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of any offer to buy the Placement Shares, nor shall there be any offer, solicitation or sale of the Placement Shares in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction.
