Mantha agreed to terms on a two-year, $9.5 million contract with New Jersey on Wednesday.
Mantha racked up 33 goals and 31 assists, setting new personal bests in both categories, across 81 regular-season games with the Penguins in 2025-26. He also tied his previous career high with 13 power-play points. With the Devils, the 31-year-old winger should be in the mix for a top-six role and power-play minutes.
