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.
Acciona has injected €40 million into its electric motorcycle subsidiary, Silence, to support growth and strengthen its financial structure. This follows a previous €62 million investment earlier in the year. Silence faced production halts due to low demand and high inventory levels, leading to a temporary employment regulation in 2024. The company's revenue was €18 million in 2024, down from €45.6 million in 2023. The capital now totals €102 million.
Loan to support digitalisation strategy and sustainability efforts
The Australian Competition and Consumer Commission (ACCC) is investigating Acciona's proposed acquisition of a competing waste-to-energy facility. This probe is prompting broader discussions on how Australia's merger regulations address issues such as creditor influence, infrastructure contracts, and the demand driven by sustainability.
