**SenesTech Announces Amendment to Equity Incentive Plan Proposal**

PHOENIX, Ariz., June 3, 2026 – SenesTech, Inc. (NASDAQ: SNES) ("SenesTech" or the "Company"), today announced that its Board of Directors has approved an amendment to the proposed changes to the Company's 2018 Equity Incentive Plan (the "2018 Plan"), which is being presented for stockholder approval at the Company's 2026 Annual Meeting of Stockholders scheduled for June 9, 2026.

As previously disclosed in the Company's definitive Proxy Statement filed on April 29, 2026, stockholders are being asked to approve an amendment to the 2018 Plan to increase the number of shares available for future equity awards. Following further review of the Company's anticipated equity compensation needs, current market conditions and stockholder considerations, the Board approved a revised amendment that reduces the number of new shares proposed to be added to the 2018 Plan from 1.7 million shares to 1.2 million shares. The Board believes these actions reflect a balanced approach to equity compensation and capital management.

Stockholders who have already submitted, or subsequently submit, a proxy card or vote via the Internet or by telephone in favor of Proposal No. 3 will be deemed to have voted in favor of Proposal No. 3 as revised by the supplemental proxy materials. Accordingly, no additional action is required from stockholders who have previously voted in favor of Proposal No. 3 and do not wish to change their vote.

Additional information regarding the revised proposal is contained in the Company's definitive additional proxy materials filed with the Securities and Exchange Commission on May 27, 2026.
