IAG's 10.9% Margin Passes the Smell Test-But 57% Bookings Say Don't Get Greedy

H1 2026 shows resilience, but the signal is mixed

IAG's first half looks solid on the surface: Revenue grew 1.0% to €16,064m, and operating profit before exceptional items was €1,757m. But adjusted EPS decreased by 10.9% to 23.6 cents. That is not the profile of a new profit regime; it is evidence of a business holding its margin in a tougher environment.

The next hard checkpoint is soon, with Q3 2026 due on 6 Nov 2026 after this 31 Jul 2026 half-year release. IAG has also booked 57% of expected H2 revenue, in line with last year. That is not weak enough to worry about immediately, but it is not firm enough to assume a smooth second half. If bookings translate into better yields, the stock can re-rate. If not, the story likely stays range-bound.

One thing this is not, at least right now, is a balance-sheet crisis. Free cash flow reached €2,905m, net debt reduced to €4,692m, and total liquidity: €11,873m. The immediate question is whether operating momentum is steady enough to support the full-year target.

Pricing power helped, but it was uneven

IAG did not have an easy half. Fuel unit costs increased 12.5% during the first half, and management says pricing and cost actions recovered about 60% of that pressure. That matters: it shows the portfolio can absorb part of a fuel shock without breaking the margin model.

But management was also clear that the recovery was not uniform. It said long-haul demand remains strong, short-haul more competitive. That mix matters more than the headline margin because it suggests part of the result still depends on a favorable demand backdrop rather than broad-based strength.

Investment needs to support margins, not just capacity

On spending, IAG has CapEx for 2026 guided at €3.4bn and 16 aircraft deliveries expected. That is meaningful investment for a group that also kept its 2026 operating margin target of 12% to 15% and said full-year capacity will be flat. The logic is straightforward: newer aircraft should improve efficiency and the product without relying on seat growth.

That leaves the setup roughly where the numbers put it: IAG still looks operationally competent, but not obviously poised for a big upside step. The key watchpoint from here is whether booking quality and pricing improve across more of the network before November confirms the trend.
