The new ownership group is expected to speak publicly for the first time next week, assuming the sale is officially approved, as expected.
The deal is for 100 percent of the Sixers for approximately $280 million. The deal does not include the NHL's Flyers, also owned by Comcast-Spectacor, or the Wells Fargo Center, which houses both professional franchises.
Under this new ownership, the Sixers will become a tenant in the Wells Fargo Center.
Harris, 46, is a founding partner at the private equity firm Apollo Global Management. He is joined in the investment group by David Blitzer of the private-equity firm Blackstone, portfolio manager Art Wrubel, and former NBA agent and Sacramento Kings executive Jason Levien. All are making private investments, having no affiliation with the firms Apollo or Blackstone.
Harris, Blitzer, and Wrubel are graduates of the Wharton School at the University of Pennsylvania.
This year, Forbes valued the Sixers at $330 million, the NBA's 17th most expensive franchise. Comcast-Spectacor bought the Sixers in 1996 for $130 million.
