Unusual Machines Inc (UMAC) experienced a significant 24-hour plunge of 8.75% during the night session, marking a sharp reversal for the drone technology company's stock.

The decline comes as a pullback from a recent substantial rally and follows the disclosure of multiple insider transactions. Executives at the company, including Allan Evans who filed to sell 500,000 shares and Hoff Brian Joseph who sold 150,000 shares, moved to liquidate portions of their holdings after the stock's surge.

This insider selling activity emerged shortly after reports indicated the Pentagon was negotiating financing agreements with several drone companies, including Unusual Machines, to expand domestic production capacity for defense-critical drone technology. The company had previously rallied nearly 50% on May 28 on optimism about potential government funding arrangements that could include both debt financing and government equity stakes.
