GLENBROOK CAPITAL MANAGEMENT 4

What Happened

• Glenbrook Capital Management, a reported 10% owner of SenesTech, purchased 3,000 shares of SenesTech, Inc. (SNES) on April 28, 2026 at $1.47 per share, for a total cash outlay of $4,407. This filing reports a purchase (transaction code P), which is a direct buy rather than a sale.

Key Details

• Transaction date: 2026-04-28; Filing date: 2026-04-30 (appears timely under Form 4 rules).
• Price and amount: 3,000 shares at $1.47 each = $4,407 total.
• Shares owned after transaction: not specified in the information provided in this summary (the Form 4 reports holdings across trusts, employee plan and managed accounts).
• Footnote: Securities are held directly by PFS Trust, Glenbrook Capital Management Inc. Employee Profit-Sharing Plan (GCM EPSP), and various funds/accounts managed by Glenbrook; Glenbrook disclaims beneficial ownership except to the extent of any pecuniary interest.
• Transaction type: Purchase (code P).

Context

• This is an institutional purchase by an investment manager that serves as manager/trustee for multiple accounts and plans, not a trade by an individual executive. The purchase amount is modest ($4.4k), so while purchases can be informative, this small dollar transaction alone is unlikely to signal a major change in insider sentiment.
