International Consolidated Airlines Group's shares slid after the company reported a second-quarter operating profit that fell short of analyst expectations and revised its capacity outlook for the year. The group posted Q2 operating profit of €1.26 billion, compared with consensus estimates of roughly €1.37 billion, a shortfall that investors interpreted as an indication of tighter near-term profitability.
Revenue in the quarter increased marginally, edging up 0.2% to €8.88 billion. Management said higher ticket yields only partially offset a mix of pressures including reduced capacity, disruptions originating in the Middle East, and timing differences associated with Easter. For the first half of the year, operating profit before exceptional items declined to €1.76 billion from €1.88 billion in the comparable period a year earlier.
Beyond the headline profit miss, a significant factor driving the share reaction was the group's decision to set full-year 2026 capacity guidance to flat, effectively walking back earlier plans for growth. That downgrade to capacity expectations weighed on sentiment and prompted investors to reassess short-term earnings trajectories.
Fuel costs are a central theme in IAG's update. At its Q1 briefing in May, IAG had already warned the market that its full-year fuel bill would likely come in at around €9 billion - approximately €2 billion higher than previously assumed - and that only about 60% of that incremental cost was expected to be recovered through pricing and cost measures. The Q2 results reinforced that these headwinds remain persistent, with jet fuel prices running roughly 77% higher year-on-year across the European airline sector.
The sector-wide nature of the pressure is underscored by the fact that IAG's European peers, including Air France-KLM and Lufthansa, are also reporting second-quarter results this week amid a general squeeze on margins across the airline industry.
Despite IAG's setback, broader equity markets were trading positively on the day. The S&P 500 was up 0.5%, the Dow Jones gained 0.6%, and the Nasdaq advanced 1.1%, suggesting that the decline in IAG shares reflected company- and sector-specific dynamics rather than a widespread risk-off move.
On the trading floor, IAG shares fell 2.6% to 427.3p, moving toward the lower end of the intraday range of 414.7p to 429.8p and remaining well below the 52-week high of 492.9p. The combination of a profit shortfall, curtailed capacity guidance, and ongoing uncertainty around fuel costs has prompted investors to mark down near-term expectations for the group.
