Curis Transitions Registered Shares to 2026 Incentive Plan After Stockholder Approval

Curis, Inc. (NASDAQ:CRIS), a Delaware corporation headquartered at 128 Spring Street, Building C, Suite 500, Lexington, MA, filed this Post-Effective Amendment to update fourteen previously filed Form S-8 registration statements. According to the filing, the purpose is to reflect that, as of March 17, 2026, shares of common stock (par value $0.01 per share) previously registered for issuance under the Fifth Amended and Restated 2010 Stock Incentive Plan and under inducement awards granted pursuant to Nasdaq Stock Market Rule 5635(c)(4) may instead be issued under the company's newly approved 2026 Incentive Plan.

The filing states that under the terms of the 2026 Plan, no new awards may be granted under the 2010 Plan as of its March 17, 2026 effective date; however, the 2010 Plan's terms and conditions continue to govern any outstanding awards granted prior to that date. Shares that remain available under the 2010 Plan, as well as shares from outstanding awards that expire, terminate, are surrendered, cancelled, forfeited, or repurchased by the company at their original issuance price, will become available for issuance under the 2026 Plan. The filing identifies 173,744 shares as the maximum number previously registered and available, as adjusted to reflect prior reverse stock splits.

The filing also includes selected financial data adjusted for the 1-for-20 reverse stock split effected on July 2, 2026. On an as-adjusted basis, the company reported a net loss per share, basic and diluted, of $24.99 for the three months ended March 31, 2026, and weighted-average shares outstanding of 968,276 for that same period. For the year ended December 31, 2025, the as-adjusted net loss per share was $11.52, with weighted-average shares outstanding of 658,297. The filing notes that "historical results are not indicative of the results that may be expected in the future."
