Acciona acquires 80% of Vertical Earth to accelerate US infrastructure growth

Acciona has agreed to acquire 80% of Vertical Earth, a Georgia-based infrastructure contractor, consolidating Atlanta as the strategic centre for its Infrastructure division's growth in the United States. The deal is expected to close before year-end, subject to regulatory approvals. Brett Johnson, Vertical Earth's founder and CEO, will retain 20% and continue leading the company. Founded in 1997, Vertical Earth generated revenues of $217 million (€191 million) in 2025 and employs over 600 professionals in Georgia and Florida. The acquisition strengthens Acciona's self-execution capacity in a strategic market. The US represents 20% of the global infrastructure industry, with potential contracts worth $303 billion this year. Acciona's Infrastructure division is expanding across the US with major projects including the SR400 motorway in Atlanta and bridge replacement over the Calcasieu River in Louisiana.
