Empower Retirement, which owns the naming rights to the Broncos’ stadium through 2039, certainly didn’t make itself any Denver fans on Sunday.

The nation’s second-largest retirement plan company drew the ire of Broncos Country on Twitter for cheering the Chiefs’ victory in the AFC title game, which secured the rival franchise’s first Super Bowl berth in 50 years.

“Get loud #ChiefsKingdom, it’s game day!,” the company’s official account tweeted pregame. “We’re ready to cheer on our partner, the @Chiefs, as they battle the Titans in the AFC Championship to secure a spot in #SBLIV!”

Then, after Kansas City cruised past Tennessee 35-24 at Arrowhead Stadium, the @EmpowerToday Twitter account followed with another tweet congratulating the team that has owned the Broncos in the division for the last four seasons. The Chiefs have won four straight AFC West titles in that time while beating Denver nine consecutive times.

“What a win!” the company said. “The @Chiefs are going to #SBLIV! #ProudPartner #ChiefsKingdom.”
