Analysis · SNES · Industrial Applications And Services
A second activist-aligned investor has surfaced at SenesTech. Justin LeBeau reports 294,773 shares, or 5.4% of the class, bought entirely in the open market for about $229,261.57 — and roughly $168,456.53 of that was spent in the last 60 days, including 229,911 shares accumulated in a joint account with his spouse between October 19 and October 26. He explicitly endorses Glenbrook's October 19 letter calling for an end to dilutive equity offerings, expense discipline and performance-based compensation, though he says he has no agreement with Glenbrook and is acting independently. That matters because Glenbrook already holds 39.95% and is pressing the board; a second holder publicly aligned with the same demands raises the pressure on management. The counterweight is that this is a small absolute position in a company that just received a Nasdaq bid-price deficiency notice on October 20, so the capital-structure fight is happening against a weak balance sheet.
