Penrith Panthers earned an AAA brand strength rating, scoring 85 out of 100 on Brand Finance's Brand Strength Index.
Brand Finance also ranked the club as the NRL's most valuable brand for a second consecutive year.
Its brand value rose 8% to $140 million in 2026.
The recognition followed a fourth minor premiership and the club's seventh consecutive appearance in a preliminary final.
Penrith extended agreements with Allam Homes and Westfund, and welcomed Ringers Western as a new partner.
Commenting on broader AFL and NRL findings, Brand Finance Australia managing director Andy Kan highlighted supporter engagement and enduring commercial relationships.
"The most resilient brands are those that can translate moments of sporting relevance into deeper supporter engagement, broader commercial appeal and enduring partnerships," Kan said.
The club's local identity, loyal supporter base and reputation for sustained excellence were reflected in its brand strength result.
