Eurotunnel shrugged off Brexit concerns and predicted a spell of growth through the EU negotiations as it increased revenues for the 15th consecutive half-year period.

The Channel Tunnel operator said the outlook is “good” for the next two years as it backed positive reports on the UK economy by the Bank of England and the European Central Bank.

Revenues increased 3% to €497 million (£445m) in the first six months of the year while earnings before interest, taxes and other charges grew by 8% to €242 million (£216m).

Bosses predict further growth in the second half thanks to growing high-speed passenger traffic from new Eurostar trains on the London to Brussels route and a new direct service to Amsterdam from the end of the year.

The company has also cut the cost of its debt to less than 4% after a partial refinancing in June, saving the company about €60 million (£54m) per year for at least the next five years.

Net profit from continuing operations increased 23% to €30 million (£27m).

The growth comes despite a 1% fall in truck traffic to about 823,000 since the start of the year, due to the difficult weather conditions in southern Europe at the beginning of the year.

Passenger shuttle traffic using the tunnel between Folkestone and Coquelles was down 7% in June compared to the same time in 2016, when the Uefa Europpean Football Championships were held in France. It is down 2% to 1.14 million since the start of the year.

Chairman and chief executive Jacques Gounon said: “Over the past 10 years, the group has focused its business model on value creation through the quality of service provided.

“The success of the partial refinancing of the debt shows the confidence of the markets in the strength of this model.

“The economic outlook for the next two years remains good and enables us to confirm our objectives.”
