Form 20-F regulatory

"filed its Annual Report on Form 20-F for the fiscal year ended December 31, 2025"

Form 20-F is the standardized annual disclosure that non-U.S. companies must file with the U.S. securities regulator when their shares are traded in the U.S.; it contains audited financial statements, a plain-language description of the business, management discussion, governance details and key risk factors. It matters to investors because it provides a consistent, comparable company “report card” and rulebook, helping buyers assess financial health, governance and risks before investing.

International Financial Reporting Standards (IFRS) financial

"its financial statements prepared in full compliance with International Financial Reporting Standards (IFRS)"

A set of globally accepted accounting rules companies use to prepare financial statements so their numbers speak the same language across borders. For investors, IFRS matters because it makes it easier to compare profitability, assets and liabilities between companies the way a common recipe or measuring tape lets you judge two cakes or two rooms fairly, which helps assess value and risk more reliably.

forward-looking statements regulatory

"This release contains statements that may be considered forward-looking statements within the meaning of Section 27A"

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 financial

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

power transmission business financial

"holds leading positions in the power transmission business in Brazil, Chile, Peru, and Bolivia"

This release contains statements that may be considered forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended. All forward-looking statements, whether made in this release or in future filings or press releases, or orally, address matters that involve risks and uncertainties, including in respect of the Company’s prospects for growth and its ongoing access to capital to fund the Company’s business plan, among others.

We do not intend and do not assume any obligation to update these forward-looking statements.
