Mills rents and sells construction equipment, aerial platforms, and formwork to infrastructure and industrial clients in Brazil.
Mills is a Brazilian equipment rental company. If a construction site needs a scissor lift to reach a ceiling, or a steel scaffold system to pour a concrete wall, Mills is one of the companies that shows up with the gear, sets it up, and takes it away when the job is done. Its customers are infrastructure builders, industrial plants, and big construction firms — the people who would otherwise have to buy expensive machines, store them, maintain them, and hope they had the right kit on the right day.

The business has two main arms. The rental side provides aerial platforms and heavy equipment on contract, which is the steady, recurring part of the story — customers pay for time with the machine, not for owning it. The other arm sells and rents formwork and scaffolding systems, the metal molds and supports that shape concrete while it sets. That second piece is closer to a supply business: Mills designs the systems and provides the engineering to make each pour work, which makes it stickier than pure machine rental. Why do customers stick with Mills instead of buying their own gear? Utilization. A tower crane or boom lift sitting idle in a yard is dead money. Renting turns a big upfront purchase into a flexible monthly cost, and Mills spreads one machine across many projects — keeping its own fleet busy is the whole engine of the model. Brazil's infrastructure and industrial buildout swings with interest rates and government spending, so the company rides a cyclical market.
Mills has had a busy corporate life. It used to be known as Mills Estruturas e Serviços de Engenharia, a name tied to its engineering-heavy roots, before rebranding around the rental and logistics side as it grew. It is listed on B3 under the ticker you gave, and its results hinge on fleet investment, contract renewals, and how much large-scale construction is actually happening in Brazil.
