Investment groups Blackstone, Global Infrastructure Partners, and Cascade assumed ownership of Signature Aviation, the largest FBO chain, effective June 1, 2021. The three investment groups joined together earlier this year after an intense bidding war to offer a combined $4.7B bid for the company. Now a privately held company, Signature will no longer be publicly traded on the London Stock Exchange."All three companies have unmatched experience successfully investing across the aviation, transportation, infrastructure, and hospitality sectors," said a company spokesperson in a statement to GlobalAir.com. "They are deeply committed to accelerating the growth of the Signature Aviation business while making a positive impact on our team, our customers, the environment, and the communities we serve."No immediate changes to day-to-day operations are expected to occur at this time.Previous reports noted that the deal would include the Epic Fuels subsidiary, as well as the company's engine repair business, but that has not been confirmed yet.
