GEELONG has locked in its future, signing a 10-year deal with local health fund GMHBA that will see Simonds Stadium renamed from 2018.
The Cats announced the agreement on Monday with the sponsor also appearing on players' shorts and the match ball during home games.
CEO Brian Cook would not reveal the financial details but said it was the biggest deal the Cats had done in his time at the club.
"We both see an amazing future together," Cook said.
The Cats are undergoing an enormous transition through eras, with redevelopment of the stadium expected to be completed in May and the club hopeful of becoming debt free in the near future due to donations from wealthy backers.
The stadium, which includes a state of the art football department, is now under the management of a recently installed Kardinia Park Trust.
