JJ Peterka Contract: How Much Does He Earn?

JJ Peterka signed a five-year contract worth $38.5 million with the Utah Mammoth on June 26, 2025, following his trade from the Buffalo Sabres. The deal carries an average annual value (AAV) of $7.7 million.

The contract secured Peterka’s future with Utah through the 2029–30 NHL season. However, his time with the Mammoth lasted only one season before he was traded to Boston in June 2026.

The contract gives Boston a young forward with established NHL scoring experience under a multiyear agreement.

JJ Peterka Trade: Why Did He Leave Utah?

JJ Peterka has been involved in two major NHL trades during his career.

In June 2025, the Buffalo Sabres traded Peterka to the Utah Mammoth in exchange for forward Josh Doan and defenseman Michael Kesselring. The move gave Peterka a fresh opportunity with Utah after four seasons in Buffalo.

However, Peterka’s stay in Utah was short. On June 26, 2026, the Mammoth traded him to the Boston Bruins in exchange for the 23rd overall pick in the 2026 NHL Draft and a conditional first-round pick in 2028.

Utah subsequently traded the 23rd pick to the Detroit Red Wings for goaltender Sebastian Cossa in a separate deal.

The Bruins acquired Peterka to add speed, shooting and scoring ability to their forward group. Boston’s management also highlighted his ability to play on either wing and contribute at even strength and on the power play.

Peterka described Boston as a good fit, partly because of his existing relationships with coaches and German teammates.
