[2] He skated for Sweden's U20 World Junior Championship in Ufa; scoring 2 goals with 2 assists and was minus-one with 4 penalty minutes in six games, where they won the silver medal.

[4] On 23 June 2018, Lindholm was traded to the Calgary Flames along with teammate Noah Hanifin in exchange for Dougie Hamilton, Micheal Ferland, and prospect Adam Fox.

[8] In light of the pandemic, the 2020–21 season was held with a revised format, with all Canadian teams playing in the temporary North Division.

Sutter made significant changes to the team's approach, and returned Lindholm to the centre position after two seasons primarily playing on the wing, now paired on a top line with wingers Gaudreau and Matthew Tkachuk that proved an immediate success.

With Gaudreau and Tkachuk, he formed one of the most dominant forward lines in the NHL, and all three members hit numerous personal and collective milestones over the course of the season.

[13] Lindholm finished the regular season with 42 goals and 40 assists for 82 points, while the Flames won the reconstituted Pacific Division.

[16] The Stars proved a greater challenge than many had anticipated, largely due to an exceptional performance from goaltender Jake Oettinger, but the Flames eventually won the series in Game 7.

[19] On 31 January 2024, with the Flames not in contention for a playoff spot, and in the final year of his contract, Lindholm was traded to the Vancouver Canucks in exchange for forward Andrei Kuzmenko, unsigned defence prospects Hunter Brzustewicz and Joni Jurmo, and first-round (Matvei Gridin) and conditional fourth-round picks in the 2024 NHL Entry Draft.

[22] Leaving the Canucks as a free agent at the conclusion of his contract, Lindholm returned to the eastern conference in signing a seven-year, $54.25 million deal with the Boston Bruins on 1 July 2024.
