Zub, 27, established National Hockey League career highs in goals (six), assists (16), points (22) and penalty minutes (60) while having skated in all but one of the team's 82 regular-season games last season. By way of tallying four points (two goals, two assists) over 14 contests in 2022-23, he moved into sole possession of 30th place among all-time Senators' defencemen in scoring earlier this season and has posted 40 points (11 goals, 29 assists) over the first 142 games of his NHL career.
"Artem's transition to North American hockey has been remarkable," said Senators general manager Pierre Dorion. "He has worked hard to establish himself as an excellent NHL player and a strong defender. He consistently helps make us a better defensive team while he's on the ice. We're pleased to reach agreement with him on an extension of this length."
Having represented his country internationally on several occasions, Zub won a gold medal as part of the Olympic Athletes from Russia team at the 2018 Winter Olympics and bronze with Russia at both the 2017 and 2019 World Championships.
