Ondas Holdings Inc. (ONDS) stock plummeted 5.18% during intraday trading on Monday, as the market reacted to news of a significant acquisition financed with company stock and a separate filing for the resale of millions of shares.

The decline followed the company's announcement that it has entered into a definitive agreement to acquire 100% of Israeli defense software company Omnisys Ltd. The deal is valued at approximately $199 million to be paid in Ondas common stock, with Omnisys shareholders eligible for up to an additional $60 million in earn-out payments. The acquisition aims to add AI-driven battlefield resource optimization software to Ondas' autonomous defense systems portfolio.

Concurrently, a regulatory filing revealed that Ondas has registered the resale of 2,264,491 unregistered shares of its common stock by certain stockholders. These shares were previously issued in connection with an earlier acquisition. Investors likely viewed the combination of a stock-funded acquisition and the potential dilution from the share resale as negative catalysts, leading to the sharp price decline.
