Curis Redirects Registered Shares from 2010 Plan to New 2026 Incentive Plan

Curis, Inc. (NASDAQ:CRIS), a Delaware-incorporated biopharmaceutical company headquartered at 128 Spring Street, Building C, Suite 500, Lexington, MA 02421, filed this Post-Effective Amendment to update fourteen existing Form S-8 registration statements. According to the filing, the amendment is required under the undertaking in Item 512(a)(1)(iii) of Regulation S-K to disclose a material change in the plan of distribution as originally disclosed in those registration statements.

The filing explains that following stockholder approval of the 2026 Incentive Plan on March 17, 2026, shares that had been registered for issuance under the 2010 Plan and pursuant to inducement awards granted under Nasdaq Stock Market Rule 5635(c)(4) will instead become issuable under the 2026 Plan. The 2010 Plan will continue to govern outstanding awards already granted before the Effective Date, and any shares tied to those outstanding awards that expire, terminate, or are otherwise surrendered, cancelled, forfeited, or repurchased may also roll into the 2026 Plan, according to the filing.

The filing includes selected financial data adjusted for the 1-for-20 reverse stock split effected on July 2, 2026. On an as-adjusted basis, Curis reported a net loss of $24,199 thousand for the three months ended March 31, 2026, with net loss per share, basic and diluted, of $24.99 and weighted-average shares outstanding of 968,276. For the year ended December 31, 2025, the as-adjusted net loss was $7,582 thousand, with net loss per share of $11.52 and 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."

What Was Disclosed

Curis filed a post-effective amendment to fourteen S-8 registration statements to reflect that 173,744 previously registered shares, adjusted for reverse stock splits, may now be issued under the 2026 Incentive Plan rather than the 2010 Plan or inducement award grants. No new securities were registered.
