On March 1, 2019, Concert Pharmaceuticals, Inc. (the "Company") entered into an Open Market Sale Agreement
SM
(the "Agreement") with Jefferies LLC ("Jefferies") with respect to an at-the-market offering program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, par value $0.001 per share (the "Common Stock"), having an aggregate offering price of up to $50,000,000 (the "Placement Shares") through Jefferies as its sales agent. The issuance and sale, if any, of the Placement Shares by the Company under the Agreement will be made pursuant to the Company's effective registration statement on Form S-3 (Registration Statement No. 333-223334). A copy of the opinion of Goodwin Procter LLP relating to the legality of the issuance and sale of the Placement Shares is attached as Exhibit 5.1 hereto.
Jefferies may sell the Placement Shares by any method permitted by law deemed to be an "at-the-market" offering as defined in Rule 415 of the Securities Act of 1933, as amended, including, without limitation, sales made through The Nasdaq Global Market ("Nasdaq") or into any other existing trading market for the Common Stock. Jefferies will use commercially reasonable efforts to sell the Placement Shares from time to time, based upon instructions from the Company (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Company will pay Jefferies a commission equal to 3.0 percent (3.0%) of the gross sales proceeds of any Placement Shares sold through Jefferies under the Agreement, and also has provided Jefferies with customary indemnification and contribution rights. In addition, the Company has agreed to reimburse certain legal expenses and fees by Jefferies in connection with the offering up to a maximum of $50,000, in addition to certain ongoing disbursements of Jefferies' counsel.
The Company is not obligated to make any sales of Common Stock under the Agreement.
The Company or Jefferies may suspend or terminate the offering of Shares upon notice to the other party and subject to other conditions. Jefferies will act as sales agent on a commercially reasonable efforts basis consistent with its normal trading and sales practices and applicable state and federal law, rules and regulations and the rules of Nasdaq.
The foregoing description of the Agreement is not complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is filed herewith as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference. A copy of the opinion of Goodwin Procter LLP relating to the legality of the issuance and sale of the shares in the offering is attached as Exhibit 5.1 hereto.
