AeroVironment's stock experienced a significant pre-market soar of 19.72% on Tuesday, following the release of the company's fiscal fourth-quarter earnings report after the prior session's close.

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. While the company's fiscal 2027 guidance came in below consensus estimates, the magnitude of the Q4 beat and the transformational nature of the fiscal year drove strong investor sentiment in pre-market trading.
