Bob Prattey, chief executive of ACC Liverpool, said: "We are pleased to confirm another successful financial year for ACC Liverpool, taking our total economic impact since opening to £860m.
"2015 will be a significant year for us with the opening of our new exhibition centre and integrated Pullman hotel. The development will enable us to host consumer and trade exhibitions, as well as increasing the number of national and international conferences and major entertainment events. We will be the only purpose-built integrated arena, convention and exhibition centre in Europe and the newest facility of its kind in the UK.
"Meanwhile we are continuing to invest in our existing venue and have made sizeable enhancements including the refurbishment of VIP boxes in the arena, wi-fi upgrades, a wider range of technical equipment and changes to our galleria. These improvements are set to continue."
Revenues for the current financial year continue to look strong and ACC Liverpool is expecting to exceed the latest turnover figures next spring.
Conference highlights for next year include the Liberal Democrats spring conference, the World Association for the Advancement of Veterinary Parasitology and the return of BBC Worldwide Showcase for the fourth time. Arena highlights include Strictly Come Dancing, Lionel Richie and Disney on Ice.
