AeroVironment, Cooper Companies and American Eagle Report Earnings After the Bell on September 9

Three companies drew the sharpest after-hours attention on September 9, 2026, as AeroVironment, The Cooper Companies, and American Eagle Outfitters each released quarterly results after the market close. The CNBC after-hours movers list highlighted all three as among the session's biggest movers once trading shifted to extended hours.

AeroVironment reported first-quarter fiscal year 2027 results for the period ended August 1, 2026. Wall Street had projected roughly $474.6 million in revenue and $0.32 per share in earnings, with the consensus EPS estimate revised upward by 8.1% in the 30 days before the print. The defense drone and systems maker entered the report carrying momentum from a $464.8 million U.S. Army laser contract and its first international order for the LOCUST system, though its stock had retreated sharply from a 52-week high of $417.86 to around $145 heading into the session.

Cooper Companies released fiscal third-quarter 2026 figures, with analysts expecting approximately $1.1 billion in sales and $1.11 in diluted earnings per share. The medical device company has beaten Wall Street EPS estimates in each of the four preceding quarters and delivered record revenue in its second quarter, with non-GAAP diluted EPS of $1.21 in Q2, up 26% year over year. American Eagle Outfitters, which had already posted record first-quarter fiscal 2026 revenue of $1.2 billion in May, also moved meaningfully in the after-hours session, with unusually heavy options activity of 41,587 contracts earlier in the regular session flagging elevated investor interest ahead of results.

Elsewhere on September 9, Comcast ranked among the worst performers in the S&P 500 during regular trading, and Hagerty shares slid on unspecified news. Options activity across large-cap technology names including Tesla, Nvidia, Apple, AMD, and Amazon was also flagged as elevated during the session.
