Perma-Fix Environmental Services, Inc. reported board actions affecting its stock plan and bylaws. On November 13, 2025, the board rescinded a 2023 amendment to the 2017 Stock Option Plan that would have increased available shares by 600,000, in order to moot a stockholder putative class action challenging the validity of that vote. The board believes broker non-votes were properly excluded but acted after a Delaware Court of Chancery ruling allowed the case to proceed.
The board simultaneously rescinded the prior share increase proposal, amended the bylaws, and approved a new amendment to the 2017 Stock Option Plan to increase authorized shares by 600,000, which will only take effect if stockholders approve it within 12 months at a special meeting or the 2026 annual meeting. No options were granted under the rescinded proposal. The bylaws were also updated to reflect recent Delaware law changes on fee-shifting and forum selection, designating Delaware courts for specified corporate disputes and U.S. federal courts for Securities Act claims.
