The Blazers sale is expected to close by the end of this year.
Dundon, 53, bought a stake in the Hurricanes in 2017 and became the majority owner in 2018. He is chairman and managing partner of the Dallas-based firm Dundon Capital Partners.
Allen’s estate announced in May that it had begun the process of selling the Trail Blazers. The billionaire co-founder of Microsoft, who died in 2018 at age 65 from complications of non-Hodgkin lymphoma, originally bought the Blazers in 1988 for $70 million.
Allen also owned the NFL’s Seattle Seahawks and was a co-owner of Major League Soccer’s Seattle Sounders.
Since his death, Allen’s sister, Jody Allen, has served as chair of both the Blazers and Seahawks and is a trustee of the Paul G. Allen Trust. Paul Allen stipulated in his will the eventual sale of his teams, with the proceeds to be given to philanthropic endeavors.
The estate has not announced plans for the sale of the Seahawks or the 25% stake in the Sounders.
