Six Flags Entertainment Corporation, the world's largest regional theme park company, has announced that revenue for the first three months of the year was $74m, down 15.9 per cent on the $88m reported in the same period in 2013.

The decline was primarily related to an attendance shift due to the 2014 Easter holiday falling in April, which caused many schools to schedule spring-break vacations in the second quarter versus the first quarter 2013.

Losses widened to $43m, compared to a loss of $38m in the first quarter of 2013.

"The increase in guest spending per capita, along with a 25 per cent increase in our Active Pass Base, which is comprised of guests in our membership plan and season pass holders, positions Six Flags to deliver another year of solid growth," said Jim Reid-Anderson, chairman, president and CEO.

Earlier this month, the company announced a new strategic partnership to build a Six Flags-branded theme park outside of North America. "This is an important component of our long-term growth strategy and the first step in expanding the Six Flags brand internationally," Reid-Anderson said.
