Originally, the contract of Mathieu Vouillamoz would have expired at the end of the 2021-22 season. Both parties did, however, decided to commit to their working relationship beyond the upcoming season.
The forward joined Genève-Servette HC's organization in 2015. Since then, Vouillamoz has only ever been under contract with the Grenats, even though he has played for HC Sierre on a loan basis from time to time.
In 32 games last season, he recorded three goals and five assists for GSHC. He also added four goals and one assist (eleven games) to his tally in the playoffs.
