The sale must be approved by the NHL's Board of Governors. No dollar amount was announced.
"Since The Walt Disney Company created the team in 1992, the Mighty Ducks have become a wonderful asset to this community, with a terrific following, a history of winning and a strong nucleus of outstanding young prospects and talented veterans," Samueli said.
"Our acquisition of the team assures that the Mighty Ducks will remain in the hands of local ownership committed to keeping the team in Orange County and putting a consistent winner on the ice."
The Mighty Ducks joined the NHL as an expansion team 13 years ago.
