Curis Transitions Legacy Stock Plan Shares to 2026 Incentive Plan

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 effective Form S-8 registration statements. The purpose of the amendment, according to the filing, is to reflect a material change in the plan of distribution originally disclosed in those registration statements: shares that had been registered for issuance under the Fifth Amended and Restated 2010 Stock Incentive Plan, as amended, and pursuant to inducement awards granted under Nasdaq Stock Market Rule 5635(c)(4), will now instead be issuable under the company's 2026 Incentive Plan.

The filing states that the 2026 Incentive Plan was approved by stockholders on March 17, 2026. Under the terms of the 2026 Plan, as of that effective date, no new awards may be granted under the 2010 Plan, though existing outstanding awards under the 2010 Plan and Inducement Awards continue to be governed by their original terms. Shares remaining available for grant under the 2010 Plan as of the effective date, as well as shares from outstanding awards that expire, terminate, are cancelled, forfeited, or repurchased, will roll into the 2026 Plan, according to the filing.

The filing also includes selected financial data adjusted to reflect the 1-for-20 reverse stock split effected on July 2, 2026. On an as-adjusted basis, the company reported weighted-average shares outstanding of 968,276 for the three months ended March 31, 2026, compared with 424,781 for the same period in 2025. For the year ended December 31, 2025, the as-adjusted net loss per share, basic and diluted, was $11.52, and for the year ended December 31, 2024, it was $137.61, according to the filing. Common shares outstanding as adjusted stood at 1,999,041 as of March 31, 2026.
