Investing.com -- American Airlines Group Inc. (NASDAQ: AAL) reported its second-quarter results on Thursday, sending its shares over 5% lower in premarket trading.

Adjusted earnings per share came in at $0.15, surpassing the analyst consensus of $0.03 by $0.12. Revenue reached a record $16.7 billion, up 16.3% YoY, meeting analyst expectations.

Despite the earnings beat, the company issued disappointing guidance, now expecting adjusted earnings per share between -$0.65 and $0.65 for fiscal 2026, citing elevated fuel costs. For the third quarter, American projects adjusted EPS of -$0.70 to -$0.10, with a midpoint of -$0.40, significantly below the analyst consensus of $0.61.

The company expects third-quarter revenue growth of 16.0% to 19.0% YoY.

"American delivered year-over-year revenue growth of more than 16% in the second quarter, exceeding our initial expectations and continuing the momentum we've built across the business," said CEO Robert Isom. "This performance reflects the strength of our commercial strategy, driven by our four pillars: elevate the customer experience, grow the global network, drive premium revenue and lead in loyalty."

The company's strong revenue performance was offset by a challenging fuel environment, with fuel expense increasing $2.2 billion, or 83% YoY. American offset nearly 50% of this fuel headwind through higher fares. Based on the forward fuel curve as of July 21, the company expects third-quarter fuel expense to increase $1.7 billion YoY, with an average fuel price of approximately $3.75 per gallon.

Premium passenger unit revenue increased 13.4% YoY, while Main Cabin rose 8.8%. Managed corporate revenue grew 26% YoY, marking the fifth consecutive quarter of double-digit growth. The company ended the quarter with $11.3 billion in total available liquidity.
