shares held in treasury financial

"INDIVIDUAL FORM SHARES HELD IN TREASURY(Article 11 of CVM Resolution #44/2021)"

Shares held in treasury are stock a company issued and later repurchased, keeping those shares in its own ‘storage’ where they typically don’t vote or receive dividends. For investors this matters because treasury shares reduce the number of shares held by the public—potentially lifting per‑share earnings and changing ownership percentages—and the company can later reissue or retire them, which affects supply and possible dilution.

forward-looking statements regulatory

"DISCLAIMER ON FORWARD-LOOKING STATEMENTS This report on Form 6-K 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.
