Tui is reportedly set to post full-year pre-tax profits in excess of €1 billion for a third year in succession, The Times reports.
Despite the summer heatwave and World Cup stymying demand earlier this year, the operator is understood to have benefited from strong late bookings.
Analysts cited by The Times expect Tui revenue to reach €19.3 billion, up from €18.5 billion last year (December-December).
Pre-tax profits, meanwhile, are expected to come in at €1.04 billion. Tui posted underlying Ebita at constant currency of €1.121 last year (up from €1.001 billion in 2016), falling to €1.102 billion including foreign exchange effects.
In September, Tui said despite the hot summer, it was still projecting profit growth of 10%.
Group chief executive Fritz Joussen said: “The financial year is closing out as we expected, with the fourth consecutive year of double digit growth in underlying Ebita (earnings before interest taxes and amortisation) since the merger.”
Joussen added Tui had experienced growth in bookings across all major markets despite a “sustained period of hot weather in Northern Europe this summer”.
While Tui felt the heat earlier in the summer, when profits fell 18% in the three months to the end of June, it the maintained its projected double-digit growth in earnings.
Tui share prices have fallen significantly June to date, down from around £17.00 to £11.05 on Monday (December 10). It will publish its full-year profits on Thursday (December 13).
Its performance comes amid a tumultuous period for rival Thomas Cook, which saw its share price plummet to less than 20p last Tuesday (December 4) before recovering to around 30p.
