Shares of AeroVironment (AVAV) plummeted 19.67% on Tuesday after the defense technology company reported disappointing fiscal third-quarter results and lowered its full-year guidance.

For the quarter ended January 25, 2025, AeroVironment's revenue of $167.6 million missed Wall Street's estimates of $196.4 million, reflecting a 10% year-over-year decline. The company cited unprecedented high winds, fires, and power outages in Southern California that disrupted its manufacturing operations and supply chain logistics.

AeroVironment also posted an adjusted earnings per share of $0.30, widely missing analysts' expectations of $0.63. The company reported a net loss of $1.8 million, compared to a net income of $13.9 million in the same period last year.

Adding to investors' concerns, AeroVironment lowered its full-year revenue guidance to a range of $780 million to $795 million, down from previous estimates of $819 million. The company also cut its adjusted earnings per share guidance to $2.92 to $3.13, well below the $3.43 estimate.

The disappointing results and guidance revisions were primarily attributed to the supply chain disruptions caused by the extreme weather conditions in Southern California, as well as recent stop-work orders from the U.S. government on certain foreign military sales contracts.
