UK theme parks group Merlin Entertainments expects to deliver earnings of between £407 million and £411 million for 2014 following a strong summer.

The company said today that its three operating groups showed continued revenue growth as the business traded well over the summer.

Trading in the Legoland Parks operating group has remained strong, benefiting from the momentum created by the release of the Lego Movie earlier in the year.

The resort theme parks operating group has seen like for like revenue growth improve in recent months, benefiting from good Halloween offerings and unseasonably warm weather in the UK.

But Merlin’s two attractions in Bangkok “show little sign of improvement and continue to drag on growth”.

Chief executive Nick Varney said in a pre-close trading statement: “As we approach the end of our first financial year as a public company, I’m pleased to report continued good trading across the business, reflecting positive underlying trends, favourable weather in the period, and this year’s exceptional performance in Legoland Parks.

“The trading in the balance of the year comprises primarily our year-round Leoland Parks in North America and the Midway Attractions operating group, including the peak season for our attractions in Australia and New Zealand.

“Whilst there is still some significant trading to come, we are confident in delivering a strong full year result.

“The performance this year has benefited from a number of one-off factors and whilst we remain positive on the outlook for 2015, our expectations remain unchanged.

“We continue to focus on our six strategic growth drivers and on delivering new memorable experiences for our visitors.”

Merlin will report its 2014 results on February 26.
