Why Is AAR CORP (AIR) Stock Down Today?

AAR Corp (AIR) shares fell 9.76% to $127.60 in the session, marking a sharp decline despite the company reporting Q4 earnings and revenue that beat expectations. The drop came after the company outlined its FY2027 guidance, which included a projected Q1 sales growth of 21% to 23% excluding legacy commercial programs, and a target for margin expansion. The stock’s sharp pullback suggests investor skepticism about the company’s forward-looking guidance and broader market conditions.

What Happened

AAR reported Q4 FY2026 results with record sales, EBITDA, and EPS, including a non-GAAP EPS of $1.53 that beat estimates by $0.15 and revenue of $928 million that exceeded expectations by $33.39 million. The company also provided a detailed earnings call outlining strategic initiatives such as Airvoyant AI and a recent contract win with Woodward. Despite these positives, the stock fell sharply, indicating that the market may have found the guidance for FY2027 insufficient to justify the current valuation. The SEC 8-K filing on July 21 confirmed the results and included the company’s financial statements and exhibits.

What The Data Shows

AAR has a market cap of $5.3 billion, with a P/E ratio of 31.3 and revenue growing 16.8% in the trailing twelve months. The stock has traded between $71.43 and $146.75 over the past 52 weeks. The recent session saw a significant drop in price, though no unusual options activity or insider filings were reported in the last 36 hours. The stock’s beta of 1.09 indicates it moves in line with the broader market, which has also seen declines in the pre-market session.

What To Watch

AAR’s forward-looking guidance for FY2027 will be closely monitored by investors. The company’s ability to deliver on its margin expansion and sales growth targets will be key to regaining investor confidence. No upcoming earnings date is provided, but coverage breadth remains elevated with eight stories published in the last 36 hours.
