New York, January 8, 2026, 19:01 EST — After-hours
- Shares up about 15% after a prospectus supplement registered 1.67 million shares for resale
- Filing tied the new shares to a payment step in Ondas’ Sentry CS acquisition
- A Form 144 showed a director planned to sell up to 300,000 shares
Ondas Holdings Inc. shares rose 14.9% to $14.01 in late after-hours trade on Thursday, swinging between $12.56 and $14.99 on the day in heavy volume.
The move came as a new prospectus supplement registered 1,671,899 shares for resale by selling stockholders, a step that can add to the stock available for sale even if nothing is sold immediately. The prospectus said Ondas will not receive any proceeds from those sales. 1
The document linked the issuance to Ondas’ November deal for Israel-based Sentry CS Ltd., saying the company paid $117.5 million in cash and issued 4,096,700 shares at closing, then paid another $2.5 million and issued the new shares on Jan. 8. It also laid out more cash and stock consideration due at later milestones, with Ondas retaining the option to pay some of that stock portion in cash. 1
Separately, Ondas said its CEO Eric Brock will appear in a fireside chat at Needham’s Growth Conference on Jan. 14 and meet investors that day, giving traders a near-term date for management commentary. 2
A Form 144 filing also showed Ron Stern, listed in the notice as a director, proposed selling up to 300,000 Ondas shares through Morgan Stanley, after an options exercise dated Jan. 8. The same filing listed several prior sales over the past three months. 3
In the prospectus, the company flagged limits that can throttle selling pace, including a provision that caps certain sales on any single day at 10% of average daily trading volume, based on the prior 10 trading days. 1
Stern also filed a Form 3 earlier this week that referenced his resignation as a director in December, while listing fully vested stock options. 4
But the new resale registration and the fresh Form 144 sale notice underline the same risk for bulls: more stock can come to market, and that overhang can pressure prices in a small-cap name that already trades in sharp bursts.
Next up, investors will watch for what Brock says at the Jan. 14 conference and how the market digests the next acquisition-related installments due later this quarter; Ondas is also expected to report results around March 11, according to Zacks. 5
