Gerdau (GGB) CFO Rafael Dorneles Sells 10,000 Shares

What Happened
Rafael Dorneles, Vice President, Chief Financial Officer and Investor Relations Officer of Gerdau S.A., sold 10,000 shares on August 6, 2026 in an open-market or private sale (coded "S"). The reported USD amount is $5.10 per share, totaling approximately $51,000. This transaction is a sale (not a purchase) and therefore is commonly viewed as routine insider selling rather than a direct bullish signal.

Key Details

• Transaction date and price: Aug 6, 2026 — 10,000 shares sold at $5.10 per share (USD), total ~$51,000.
• Price translation: Footnote F1 — the price was denominated in Brazilian reais and converted to USD using the Aug 6, 2026 selling rate of R$5.1017 per US$1.00 (Central Bank of Brazil).
• Additional footnote F2 is present in the filing (R$5.0140 per US$1.00 on May 22, 2026) but F1 applies to this sale.
• Shares owned after the transaction: not disclosed in the provided summary of the filing.
• Filing timeliness: Form filed on Aug 10, 2026 (four days after the trade). Form 4s are typically due within two business days of the transaction, so this appears to have been filed late.

Context

This report documents a direct sale; there is no indication here of option exercises, awards, gifts, or 10b5-1 plan language in the provided details.
