Ryanair Holdings Plc cut its profit guidance, saying full-year earnings are likely to increase by about 7 percent rather than the 12 percent previously estimated as the decline in the British pound weighs on fares. Net income is likely to be in a 1.3 billion euro to 1.35 billion euro range ($1.43 billion-$1.49 billion), rather between 1.375 billion euros and 1.425 billion euros as previously estimated, Dublin-based Ryanair said in a statement Tuesday. “The recent sharp decline in sterling post-Brexit will weaken second-half yields by slightly more than we had originally expected,” it said. “While higher load factors, stronger traffic growth and better cost control will help to ameliorate these weaker revenues, it is prudent now to adjust full-year guidance.” Britain is expected to account for about 26 percent of Ryanair sales this year, the carrier said.
