Form 20-F regulatory

"has 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.

American depositary shares financial

"Shareholders and holders of American depositary shares representing CSN’s shares have the ability to, upon request"

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

forward-looking statements regulatory

"This press release may contain 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.

audited financial statements financial

"receive a hard copy of CSN’s complete audited financial statements, free of charge"

Audited financial statements are a company's financial reports—like its income, expenses, assets and debts—that have been examined and verified by an independent accountant to confirm they are accurate and complete. For investors, an audit is like having a trusted mechanic inspect a used car: it increases confidence that the financial picture is reliable, reduces the risk of hidden problems, and supports better decisions about valuing or trusting the company.
