COSCIENS Biopharma Inc. filed a Form 15 with the Securities and Exchange Commission on July 6, 2026. Form 15 is a certification and notice of termination of registration of a class of securities, or suspension of the duty to file reports under the Securities Exchange Act of 1934.

The filing covers the company's common shares and lists no other class of securities for which a duty to file reports remains. The company marked Rule 12g-4(a)(1) and Rule 12h-3(b)(1)(i) as the provisions it relies on to terminate or suspend the duty to file reports.

The notice gives the approximate number of holders of record as of the certification date as 153.

The notice is dated July 6, 2026. Once the duty to file reports ends, the company would no longer be required to file periodic reports such as annual reports.
