“Today’s announcement represents another milestone in our strategic North-American growth initiative to seek out park acquisitions that expand our addressable market,” said Six Flags Chairman, CEO, and President, Jim Reid-Anderson. “These are all fantastic properties that complement our existing portfolio and provide tremendous added value and cross-visitation opportunities for our extensive Membership and Season Pass base.”

The parks joining the Six Flags family are:

Wet n’ Wild Splashtown, Houston’s largest waterpark
Wet n’ Wild Phoenix, the largest waterpark in Arizona 
Darien Lake near Buffalo, NY
Frontier City in Oklahoma City 
White Water Bay, near Frontier City

Six Flags is the largest regional theme park operator in the world and once the deal is official, the company will be the largest waterpark operator in North America.

With the addition of these five properties that entertained approximately two million guests in 2017, there will be an additional 20 million guests within a 100-mile radius of a Six Flags park, significantly expanding the company’s national footprint, the news release said.
