PolarCool AB (publ.) has secured a breakthrough 3-year league-wide agreement with the Czech professional Ice Hockey League - Extraliga, worth 2,5 MSEK, starting from the 2025/2026 season.

Under the agreement, PolarCap® will be implemented across the league, as a standardized part of concussion management in the league. This marks a significant progress for PolarCool's presence in European ice hockey and represents an important step toward achieving positive cash flow for the company.

The league-wide adoption follows the successful introduction of PolarCap® during the 2025 Czech playoff semi-finals and finals-an initiative that generated widespread interest from both the league and participating teams. This momentum has now led to a full-league rollout, marking a major advancement in player safety and welfare across the Extraliga.

-Player safety is our top priority. By introducing PolarCap® across the league, we are taking a major step forward in our medical protocols. The system's clinically proven benefits, especially in reducing long-term absence after head injuries, made this an easy decision. A league-wide agreement ensures that every player has access to immediate, effective treatment.

PolarCool's CEO, Erik Andersson, comments;

-We are proud that Extraliga is prioritizing player safety by adopting our technology across the league . This decision reflects both the strong clinical support and growing trust in PolarCap®. Transitioning from individual team agreements to full league-wide partnerships has been a key strategic goal for PolarCool, making this agreement a significant breakthrough in expanding our presence in the European ice hockey market. We look forward to building a strong and lasting partnership.
