How Curis Restructured Its Equity Plan Registration After the 2026 Plan Approval

Curis, Inc. (NASDAQ:CRIS), a Delaware-incorporated oncology-focused biopharmaceutical company headquartered at 128 Spring Street, Lexington, MA, filed this Post-Effective Amendment to update fourteen existing S-8 registration statements following its stockholders' approval of the 2026 Incentive Plan on March 17, 2026. The company explained that the amendment was required pursuant to the undertaking in Item 512(a)(1)(iii) of Regulation S-K to disclose a material change in the plan of distribution as originally set out in those registration statements.

Under the terms of the 2026 Plan, the 173,744 shares previously registered for issuance under the 2010 Plan and the inducement award grants under Nasdaq Stock Market Rule 5635(c)(4) will now be available for issuance under the 2026 Plan. The 2010 Plan remains in effect only to govern awards that were outstanding as of the Effective Date. Any shares tied to those outstanding awards that expire, are forfeited, cancelled, or repurchased at their original issuance price will also roll into the 2026 Plan's available pool, according to the filing.

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, with weighted-average shares outstanding of 968,276. For the year ended December 31, 2025, the as-adjusted net loss per share was $11.52, with weighted-average shares of 658,297. The filing states that "historical results are not indicative of the results that may be expected in the future."
