CHESTERMAN THOMAS C 4

What Happened
Thomas C. Chesterman, SenesTech’s Chief Financial Officer and Treasurer, was awarded 75,000 shares on 2026-06-15 as a derivative grant (transaction code A). The shares were reported at a $0.00 acquisition price (no cash paid). This was an award/compensation grant rather than an open-market purchase or sale.

Key Details

• Transaction date: 2026-06-15; Form 4 filed: 2026-06-17 (filed timely).
• Transaction type: Award/Grant (derivative) — 75,000 shares acquired at $0.00.
• Vesting: Footnote indicates vesting in 12 equal quarterly installments over 3 years.
• Shares owned after transaction: Not specified in the filing.
• No sale or purchase on the open market; not a cash exercise or tax-withholding report.

Context
This is a standard equity compensation grant to an executive. Because the award vests over time, the shares will be delivered (or become exercisable/transferable) in quarterly installments over three years, which aligns incentives for retention and performance. Awards are different from purchases (which can indicate personal bullishness) and from immediate sales; they do not necessarily signal a near-term trading intent.
