Rhea-AI Filing Summary

Aura Minerals director-linked entities reported several derivative transactions involving Brazilian Depositary Receipts (BDRs) and cash-settled total return swaps tied to Aura Minerals Common Shares. All positions are held by entities managed by Kapitalo Investimentos Ltda., which may be deemed indirectly beneficially owned by director Bruno Sousa Mauad.

On June 18–19, 2026, Kapitalo-managed clients settled two cash-settled total return swaps, each referencing Aura Minerals BDRs, at settlement prices of $20.68 and $20.86 per BDR. The filing also shows securities lending agreements under which title to certain securities temporarily transferred to counterparties, while clients may still be deemed beneficial owners because the arrangements can be discontinued at any time.

In addition, a Kapitalo-managed entity bought 200 BDRs at $21.25 in an open-market purchase. Each BDR represents one-third of a Common Share. After these transactions, indirect positions reported through BDRs and related derivatives remain significant, but the filing reflects a net reduction in derivative exposure combined with small net BDR purchases.

Brazilian Depositary Receipts financial

"Brazilian Depositary Receipts ("BDR") are certificates representing Common Shares"

Brazilian Depositary Receipts (BDRs) are certificates traded on Brazilian exchanges that represent ownership of shares in foreign companies, allowing local investors to buy and sell exposure to those overseas stocks without opening foreign brokerage accounts. They matter because they let investors diversify across global companies using local currency and trading hours, similar to buying a locally issued voucher for a foreign product, while still exposing portfolios to the performance and risks of the underlying foreign shares.

cash-settled total return swap financial

"Kapitalo entered into a cash-settled total return swap pursuant to which it will pay any increase"

securities lending agreements financial

"entered into securities lending agreements whereby title to the securities of the Issuer transferred"

beneficial ownership financial

"such clients may be deemed to continue to have beneficial ownership over the securities reported herein"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

final valuation date financial

"The final valuation date (subject to early termination by the parties) is May 25, 2027"
