Oi posts R$36.4bn loss, bankruptcy declared amid telecom collapse

Brazilian telecom Oi reported a R$36.4 billion loss for 2025, reversing a R$9.61 billion profit in 2024, as the company entered bankruptcy. Revenue fell 18% to R$2.59 billion due to legacy operations shrinking and asset sales. The loss underscores the final collapse of a once-major carrier, with implications for creditors and the Brazilian telecom sector.
