Eurotunnel achieved higher revenues in 2010 as demand from passengers lifted traffic on its shuttle services through the Channel Tunnel.
Car shuttle traffic was up 11% on 2009, while coach and lorry traffic also rose, but rail freight numbers fell.
The company said there was an overall increase of 3% in passengers travelling through the tunnel.
Eurotunnel also generates income by charging other freight and passenger services, such as Eurostar, to use the tunnel.
Revenues were up 26% at 736.6m euros (£617 million), the Channel Tunnel operator announced.
Chief executive Jacques Gounon said: “Despite the very difficult economic situation, Eurotunnel’s activities have shown strong growth.
“Regaining our market share across the Channel has been continuous and we have, at the same time, successfully integrated the new rail freight businesses. The group is ready to continue in the same vein.”
Eurotunnel’s fourth-quarter revenues were up 29% as truck shuttle traffic rose by 35%.
“The extreme bad weather in December 2010 has had a significant impact on the roads leading to and from the terminals and speed limits on Eurostar trains affected the volumes throughout the month, which could therefore have been even better,” Eurotunnel said.
