GATX Expands Stake in GABX Leasing to One-Third

The transaction grants GATX significant governance influence within the joint venture. Under the updated LLC agreement, the firm now holds joint approval rights over critical corporate activities, including equity issuances, new debt incurrence, capital calls, and major transactions. While Brookfield Infrastructure Partners and its institutional affiliates retain the majority stake and continue to serve as the managing member, the amendment formalizes GATX’s role as a direct participant in operational decision-making.

This move aligns with a 2026 agreement that provides GATX with a series of structured call options. These provisions allow the corporation to incrementally increase its equity until it potentially controls the entire joint venture. Until GATX achieves full ownership, Brookfield will maintain its position as the managing member of the holding company.
