Luis Camino
President, CEO & Executive Director

Good afternoon, and a very warm welcome to our Q1 '26 results presentation. Thank you for attending today. I'm joined by Carol, our CFO. Let's begin.

So please turn to Slide 4 for our takeaways from the quarter. Amadeus opened the year with solid growth and profitability following the strong momentum we saw in quarter 4 of last year. In March, the situation in the Middle East resulted in a moderation of our volume evolution, slowing our performance in the quarter. Nevertheless, for Q1, Amadeus posted high single-digit growth at constant currency with group revenue growing 8%, adjusted EBIT increasing by 7% and adjusted diluted EPS expanding by 9%.

For March, the developing situation in the Middle East generated disruptions in air traffic in the region, namely origin-destination and stopover traffic. This also impacted the bookings associated with this air traffic, primarily through an increase in cancellations. These kind of effects are well aligned with what we have seen in similar situations in the past. Despite this, our strength in Q1 stemmed from solid momentum in January
