Mat Ishbia bought a 57 percent controlling stake of the Phoenix Suns for $2.28 billion, sources told ESPN's Baxter Holmes. Ishbia is buying his stake at a $4 billion valuation.

Robert Sarver personally sold his 37 percent stake to Ishbia for $1.48 billion. Sarver's group bought the franchise from Jerry Colangeo for $401 million in 2004.

Ishbia assumed ownership of the Suns shortly before the trade deadline and their trade for Kevin Durant.
