Easyjet said the vote meant “additional economic and consumer uncertainty is likely this summer” and it expected revenues to fall as a result.
Shares in the carrier sank 15% after its statement.
Foxtons said it expected profits would be “significantly lower” in 2016 from a year earlier, and its shares dived 20%.
In addition to the uncertainty caused by the EU referendum vote, Easyjet said trading conditions in May and June had been “extremely challenging”.
It said strikes in France, severe weather and issues at Gatwick had hit demand, and meant pre-tax profits in the third quarter had been hit by £28m.
The airline said that the uncertainty caused by the referendum result meant “revenue per seat at constant currency in the second half will now be down by at least a mid-single digit percentage compared to the second half of 2015”.
“In addition, recent movements in fuel prices and exchange rates are now expected to add around £25m of additional cost in the year to that guided at the half-year results.”
Ryanair: ‘To focus growth on European Union’
27 June 2016 (BBC)
Ryanair will not deploy new aircraft on routes to and from the UK next year, following the Brexit vote, and will instead focus on the European Union.
The Irish low-cost airline, will “pivot all of our growth into the European Union,” chief executive Michael O’Leary told the Wall Street Journal.
Ryanair carries more than 100 million passengers a year and UK routes account for 40 million of those travellers.
Ryanair has its largest hub at London’s Stansted Airport.
The airline’s shares have fallen more than 23% since the United Kingdom voted on Thursday to leave the European Union.
Mr O’Leary, one of the most vocal business leaders campaigning in favour of continued EU membership, had repeatedly warned he would cut investment in Britain if it voted to leave.
He said the airline’s overall growth targets remained unchanged.
Mr O’Leary said he expected three or four months of “considerable uncertainty” due to the British vote, but forecast a limited impact on near-term bookings to and from Britain.
