SenesTech Proposes Key Adjustments to Equity Incentive Plan

On June 3, 2026, SenesTech, Inc. (NASDAQ: SNES) made a significant announcement regarding its Equity Incentive Plan. The company's Board of Directors has approved an amendment to enhance the original proposal related to the 2018 Equity Incentive Plan, which is set to be voted on during the upcoming 2026 Annual Meeting of Stockholders scheduled for June 9, 2026.

In a previous communication, detailed in the definitive Proxy Statement filed on April 29, 2026, it was conveyed that the company seeks shareholder approval for amendments that would increase the number of shares allocated for future equity awards. However, after careful evaluation of the company’s expected equity compensation requirements, current market dynamics, and feedback from shareholders, the Board has decided to modify the proposal. The amendment now suggests a reduction in the number of new shares to be integrated into the 2018 Plan from 1.7 million shares to 1.2 million shares.

This revision is seen as a careful balance between managing equity compensation and maintaining responsible capital management practices. The Board feels that this adjusted approach will better align with the interests of shareholders while reflecting the evolving landscape of the company’s compensation needs in light of current market conditions.

Shareholders who have already cast their votes through proxy cards or other voting methods in support of Proposal No. 3 will automatically be considered to have voted in favor of the newly revised proposal. No further action is needed for those wishing to maintain their original votes, providing ease of process for stakeholders during this time.

For those interested in additional details regarding this amended proposal, the company's definitive additional proxy materials were filed with the Securities and Exchange Commission on May 27, 2026, and are available for review.
