Ambipar Emergency Response provides environmental emergency response and industrial field services to companies that handle hazardous materials or operate in sectors prone to environmental incidents. Ambipar serves over 11,000 clients across 41 countries, including transport companies and large multinationals in chemicals, oil and gas, mining, logistics, pulp and paper, and steel. No single customer accounts for more than 10% of revenue. Ambipar organizes its services into three units: Field Services, Maintenance & Routine Emergency (~82% of FY24 revenue), which covers industrial maintenance, tank and silo cleaning, soil remediation, and decontamination; Subscription (~12%), where customers pay a fixed monthly fee for standby emergency coverage under one-to-three year contracts; and High Impact Emergency (~6%), which covers large-scale events like offshore oil spills, wildfires, and dam collapses. Brazil (~46% of FY24 revenue) and North America (~42%) are Ambipar's two largest markets, with the North American business built largely through acquisitions. Ambipar's cost base is weighted toward labor (~7,400 employees) and physical assets like vehicles, vessels, and aircraft. Growth has been primarily acquisition-driven — 36 deals since 2008 — though management has shifted toward organic growth and deleveraging since 2023. Ambipar argues its key differentiators are geographic scale, breadth of services across the full emergency response value chain, and the ability to offer multinationals a single global provider with consistent standards.
