On August 6, 2026, Solid Biosciences Inc. (the “Company”) filed a prospectus supplement (the “Prospectus Supplement”) under the Company’s universal shelf registration statement on Form S-3 (File No. 333-287325) that was originally filed with the Securities and Exchange Commission (the “SEC”) on May 15, 2025 and was declared effective by the SEC on May 27, 2025 (the “Registration Statement”), relating to the offer and sale of a total of up to $200.0 million of shares of the Company’s common stock, par value $0.001 per share (the “Shares”), pursuant to an Amended and Restated Sales Agreement, dated March 13, 2024, with Jefferies LLC (the “Sales Agreement”). The Company had filed a prior prospectus supplement to the Company’s universal shelf registration statement on Form S-3 (File No. 333-277871) with the SEC on May 15, 2025 (the “Prior Prospectus Supplement”) relating to the offer and sale of shares of the Company’s common stock having an aggregate offering price of up to $85.0 million pursuant to the Sales Agreement. As of the date of the Prospectus Supplement, the Company had issued and sold shares of common stock for aggregate gross sale proceeds of approximately $85.0 million pursuant to the Sales Agreement and the Prior Prospectus Supplement. Upon the filing of the Prospectus Supplement, the Company will not make any offers or sales of its common stock pursuant to the Prior Prospectus Supplement.

Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the Company, has issued a legal opinion relating to the Shares. A copy of such legal opinion, including the consent included therein, is attached as Exhibit 5.1 hereto.

The Shares are registered pursuant to the Registration Statement and the base prospectus contained therein, and offerings for the Shares will be made only by means of the Prospectus Supplement. This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction.
