Curis Transitions Prior Plan Shares to 2026 Incentive Plan After Reverse Split

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 prior Form S-8 registration statements. According to the filing, the purpose 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 company's Fifth Amended and Restated 2010 Stock Incentive Plan and under inducement awards granted pursuant to Nasdaq Stock Market Rule 5635(c)(4) will now, to the extent available, be issued under the 2026 Incentive Plan instead.

The filing notes that stockholders approved the 2026 Incentive Plan on March 17, 2026. Under the 2026 Plan's terms, shares that remained available under the 2010 Plan as of that date, as well as shares from outstanding awards that expire, terminate, are surrendered, cancelled, forfeited, or repurchased at their original issuance price, become available for issuance under the 2026 Plan. The company disclosed that the maximum number of shares previously registered under the fourteen registration statements that were available for issuance under the 2010 Plan and under the Inducement Grants was 173,744 shares, as adjusted for the company's prior reverse stock splits.

The filing also includes selected financial data adjusted to reflect a 1-for-20 reverse stock split effected on July 2, 2026. On an as-adjusted basis, the company reported a net loss of $24,199 thousand and net loss per share of $24.99 for the three months ended March 31, 2026, compared with a net loss of $10,616 thousand and net loss per share of $24.99 for the three months ended March 31, 2025.
