"I could not be happier. To own the Rockets in my hometown of Houston is a dream come true," he said in a release. "I promise to continue to make this city proud of the Rockets and to do what we can to bring home a championship."
Fertitta purchased the team for the record price of $2.2 billion after Leslie Alexander agreed to sell the team.
"Everything is a relationship, in business and everything. This is a great relationship that I hope the city of Houston is as happy as I am. They're my partner and I'm their partner," Fertitta added.
At Fan Fest, Fertitta said he wanted to show the city of Houston and Rockets fans that he loved being part of "this."
