Planet Fitness has made a last-minute bid to acquire Blink Fitness, a budget gym chain owned by Equinox Group that filed for Chapter 11 bankruptcy in August.

Previously, Blink accepted a $121 million offer from U.K.-based Pure Gym, which plans to expand into the U.S. by acquiring Blink’s approximately 60 locations. However, Planet Fitness, which operates over 2,000 locations across the U.S., has submitted a higher competing bid, offering up to $153 million.

The move sets up a showdown in Delaware bankruptcy court, where both offers will be evaluated to decide which one will allow Blink to pay off its creditors and exit bankruptcy most effectively.
