Formenton signed a one-year, $850,000 contract with the Oilers on Wednesday.
Formenton had 18 goals and 32 points in 79 regular-season outings with Ottawa in 2021-22, but he hasn't played in the NHL since. The 26-year-old has instead played with Ambri-Piotta of Switzerland's National League, most recently recording 13 goals, 23 points and 48 PIM in 42 regular-season appearances in 2025-26. He'll compete for one of Edmonton's bottom-six spots during training camp.
