IAG shares drop as strong Q2 results tempered by H2 outlook concerns

International Consolidated Airlines Group (IAG) reported a robust second-quarter operating profit of €1.68 billion, up 35.4% and significantly exceeding analyst expectations, driven by strong travel demand, favorable fuel costs, and currency tailwinds. Despite this strong performance, a 2.9 percentage point improvement in first-half operating margin, and a planned €1.5 billion shareholder return in 2025, IAG shares declined 2% as investors focused on potential second-half softness, particularly in US economy leisure travel. While Jefferies analysts suggest potential 4% consensus upgrades to full-year net profit, concerns over declining passenger revenue per available seat kilometer (PRASK) in H2 and the noted demand softness may temper expectations, despite IAG lowering its 2025 non-fuel unit cost guidance.

Analysis

International Consolidated Airlines Group (IAG) reported a strong second quarter, with operating profit before exceptional items rising 35.4% to €1,680 million, a figure that surpassed analyst consensus by 16%. This performance was driven by resilient travel demand, favorable currency movements, and lower fuel costs, contributing to an 8.0% year-over-year revenue increase to €15,906 million. Despite these robust results and the announcement of a €1.5 billion shareholder return program for 2025, the company's shares declined 2%. This negative market reaction appears to stem from forward-looking concerns, specifically the company's disclosure of "some softness in US point-of-sale economy leisure" travel. While IAG has improved its outlook on cost control by lowering its 2025 non-fuel unit cost guidance, investor sentiment is tempered by the fact that second-half booking revenue is merely in-line with the prior year. Jefferies analysts project a potential 4% upgrade to full-year consensus net profit, but this is counterbalanced by worries over a potential decline in passenger revenue per available seat kilometer (PRASK) in the second half, which is weighing on the stock.

Key Decisions for Investors

• Investors should weigh the immediate positive of a €1.5 billion capital return program and strong Q2 earnings against the market's forward-looking concern about a potential deceleration in demand, as evidenced by the negative share price reaction.
• Closely monitor forward-looking metrics, particularly passenger revenue per available seat kilometer (PRASK) and any management commentary on US and leisure booking trends, as these are the key variables driving current uncertainty.
• Consider that while the improved non-fuel unit cost guidance provides a buffer, a materialization of the noted demand softness could offset these operational gains, making revenue trajectory the critical factor for second-half performance.
