Six Flags Entertainment Corporation, the world's largest regional theme park company, has announced record financial performance in the second quarter 2014, as revenue grew four per cent to $377m, fuelled by higher guest spending.

Adjusted EBITDA for the three-month period was $145m, up five per cent year over year.

"We are squarely focused on executing our long-term strategy and remain confident in our ability to deliver yet another record year in 2014," said Jim Reid-Anderson, chairman, president and CEO of Texas-based Six Flags.

During the quarter, the company announced a new strategic partnership to build multiple Six Flags-branded theme parks in China.

"Our ongoing initiative to expand the Six Flags brand internationally is an exciting and important component of our long-term growth strategy," Reid-Anderson said.

"We look forward to ongoing success in this area and working closely with our new partners in China and the Middle East."
