On November 13, 2025, the board rescinded a 2023 amendment to the 2017 Stock Option Plan that would have increased available shares by 600,000, in order to moot a stockholder putative class action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The board simultaneously rescinded the prior share increase proposal, amended the bylaws, and approved a new amendment to the 2017 Stock Option Plan to increase authorized shares by 600,000,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 No options were granted under the rescinded proposal.
