Greenlight is facing fines and legal issues due to tires being found in protected wetlands. They are considering developing a tire recycling business or acquiring RubberUp, an existing tire recycling company. PwC recommends Greenlight acquire RubberUp to improve their sustainability efforts. Acquiring RubberUp would provide tax benefits from lower tax rates and help Greenlight maximize profits to reinvest in the future. PwC's services could assist Greenlight with financial due diligence, mergers and acquisitions, and ensuring a successful transition.
