The message comes on the same day as the two latest years' Stanley Cup finalist begins the regular season.
Ekholm has written a three-year contract worth four million dollars, equivalent to just under 38 million kronor per season.
The Swedish defender is thus going down in salary from next season. His current two-year contract gives him 59 million dollars per season.
Ekholm came from Nashville in the 2022–23 season and made 33 points (9 goals + 24 assists) in 65 matches last season, averaging 22 minutes in playing time.
Mattias Ekholm is a candidate for Tre Kronor's Olympic Games team, played in the Four Nations in February and has won a World Championship gold.
