Increased visitor numbers drove half year revenue 6.1% higher at Merlin Entertainments, helping the company return to the black and prompting a half year dividend payment of 2p a share.
However, while the attraction operator delivered a good performance, particularly by its Legoland parks, it said the strength of sterling had "reduced reported growth significantly", with the overall impact totalling £22m.
Visitor numbers rose 6.6% from 25.8m to 27.5m year-on-year, driving revenue up by £30m to £513m. At constant currency turnover was 11.2% higher, and up 8.1% on a like-for-like basis.
The group swung from a loss of £11m to a profit of £40m, while adjusted earnings per share came in at 2.8p compared to a loss of 1.2p in the first half of 2013.
The improved numbers came thanks to further growth from the existing estate, the continued international roll out of its brands, better weather in northern Europe, as well as the promotional activity of The LEGO Movie in the first quarter, which helped drive brand awareness.
It also offset a relatively weaker performance by the Midway Attractions Operating Group, which was affected by the strength of sterling, political disruption in Bangkok and severe cold weather in North America.
Chief executive officer Nick Varney said: "Against a backdrop of ongoing currency headwinds, we have delivered further growth in visitor numbers, revenues and profits, with continued delivery from our existing estate, underpinned by the ongoing roll out of our unique portfolio of international leisure brands."
He also reiterated that year-on-year comparatives are set become "considerably more difficult" in the third quarter as a result of the strong summer trading period in 2013, although its expectations for the full year remain unchanged.
"Merlin continues to execute on its strategic growth drivers and we anticipate delivering further progress across the group over the balance of the year," Varney continued.
"As demonstrated by the opening of the first Dungeon in North America and the recently announced plans for Legoland Japan, we will continue to grow and diversify the business by both geography and brand, focusing on delivering memorable experiences for our 60m visitors."
A maiden interim dividend payment of 2p was declared.
Since the period end, trading has been in line with the group's expectations.
