AeroVironment's stock experienced a significant 24-hour soar of 20.14%, with the major movement occurring in after-hours trading on Monday, following the release of the company's fiscal fourth-quarter earnings report.

The surge was driven by the defense technology company reporting quarterly results that substantially exceeded analyst expectations. AeroVironment posted adjusted earnings per share of $1.84, beating the consensus estimate of $1.46 by 26%, while revenue of $641.6 million surpassed the expected $558.8 million by approximately 15%. Revenue more than doubled compared to the same period last year, bolstered by contributions from recent acquisitions including BlueHalo and higher product and service sales.

The company also reported a funded backlog of $1.2 billion, providing visibility into future revenue, and issued fiscal 2027 guidance. Management highlighted a transformational fiscal year and the company's positioning to capture rising global demand across its drone and advanced technology portfolios, which contributed to the positive investor sentiment.
