Oi stock faces a three document filing deadline

Oi stock (ISIN BROIBRACNOR1) is tied to a three-document reporting deadline on October 7, 2026, covering overdue filings for the third quarter of 2025, fiscal year 2025 and the 2026 reference form. The schedule follows the company's bankruptcy and the cancellation of its B3 listing.
Three filings reach a deadline
According to Ativo Virtual on October 2, 2026, Oi's judicial estate said it planned to release three documents by October 7. The package includes the third-quarter 2025 ITR, the 2025 DFP and the 2026 reference form.
The reporting periods give investors three different reference points: September 30, 2025, December 31, 2025, and the 2026 corporate-information period. The same filing also said work had started on quarterly reports for March 31, 2026, and June 30, 2026, linking the deadline to a broader effort to update the company's periodic disclosures.
B3 listing canceled after bankruptcy
The market structure changed before the filing deadline. Ativo Virtual reported that B3 canceled the listing of OIBR3 and OIBR4 after Oi's bankruptcy, with the relevant notice dated September 16, 2026, and the company communication issued on September 18, 2026.
The bankruptcy was confirmed by the Rio de Janeiro state court on August 25, 2026, while the related judgment was published on September 2, 2026. The shares remain recorded with Banco do Brasil as registrar, while the company retains its public-company registration with Brazil's securities regulator, according to the same September 18 filing.
Asset sale highlights remaining operations
Oi's remaining fixed-line operation also moved toward a new owner. Seu Dinheiro reported on September 7, 2026, that Anatel authorized the transfer of Oi Servicos Telefonicos to Metodo Telecomunicacoes under conditions for financial guarantees and service continuity. The transaction had been agreed at BRL 60.1 million.
The Rio Times reported on September 19, 2026, that shareholders rank behind creditors in the liquidation process and that the shares can no longer be bought or sold on B3. For investors, the three-document deadline is therefore primarily a disclosure milestone within a bankruptcy process, rather than a conventional earnings catalyst.
Oi stock remains outside B3 trading
Oi stock is a Brazilian telecommunications security identified by ticker OIBR3, but the B3 listing cancellation changes how holders register their ownership. The October 7, 2026 filing deadline is the next dated corporate checkpoint.
