forward-looking statements regulatory

"This release contains statements that may be considered forward-looking statements"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

hydrocarbon production technical

"it is responsible for more than 60% of the hydrocarbon production"

power transmission technical

"holds leading positions in the power transmission business in Brazil"

Power transmission is the network of high-voltage lines, substations and equipment that carries electricity from where it’s generated to the local distribution systems that deliver it to homes and businesses. Think of it as the highway system for electricity; its condition and capacity determine how reliably power flows, how costly upgrades are, and how easily new energy sources can connect—factors that directly affect utility revenues, capital spending and long-term investor returns.

road concessions technical

"road concessions in Chile, and the telecommunications sector"
