Item 1.01  Entry into a Material Definitive Agreement.

On August 6, 2026, Aclaris Therapeutics, Inc. (the “Company”) entered into a Second Amended and Restated Sales Agreement (the “Amended ATM Agreement”) with Leerink Partners LLC (“Leerink”) and Cantor Fitzgerald & Co. (“Cantor”) under which the Company may offer and sell, from time to time at the Company’s sole discretion, shares of common stock through Leerink and Cantor as sales agents. The issuance and sale, if any, of common stock under the Amended ATM Agreement will be made pursuant to a registration statement on Form S-3. The Amended ATM Agreement amends and restates the amended and restated sales agreement with Leerink and Cantor, dated February 27, 2025, which provided for the offer and sale of up to $100.0 million of common stock from time to time through Leerink and Cantor as sales agents.

Leerink and Cantor may sell shares of the Company’s common stock 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. Leerink and Cantor have agreed to use commercially reasonable efforts to sell the Company’s common stock from time to time, based on the Company’s instructions (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Company will pay Leerink and Cantor a commission equal to 3.0% of the gross sales proceeds of any common stock sold through Leerink and Cantor under the Amended ATM Agreement. The Company provided customary representations, warranties and covenants, and the parties agreed to customary indemnification rights.

The Company is not obligated to make any sales of common stock under the Amended ATM Agreement. The offering of shares of common stock pursuant to the Amended ATM Agreement will terminate upon the termination of the Amended ATM Agreement in accordance with its terms.

The foregoing description of the Amended ATM Agreement is not complete and is qualified in its entirety by reference to the full text of the Amended ATM Agreement, a copy of which is filed herewith as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

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