I don’t believe that this is correct. My recollection is at the time he paid for controlling ownership when he first bought the team (51+%) but that the number you have for $420M was not the payment, but the valuation for which his payment was calculated. He only paid around $200+ million. Then later paid the rest of the money.
Numbers are tough to pin down.
I saw another article that the value was $550M (plus, Dundon paid down team debt from $200M to $100M). From N& O article:

Tom Dundon finalized the deal to buy the Carolina Hurricanes on Jan. 11, 2018, and shared his thoughts on why he decided to buy a hockey team, why the Hurricanes and how improving the fan experience will be his top priority.
Thomas Dundon, the new owner of the Carolina Hurricanes, comes across as a man of many ideas, constantly in motion, looking to make changes and move forward.
Dundon, a self-made billionaire from Dallas, finalized the deal Thursday in which he took over majority ownership of the Hurricanes from Peter Karmanos Jr.,
the National Hockey League announced. Dundon will own 61 percent of the NHL team, which was valued at $550 million, with an option to buy the remainder in three years."
