Companhia de Saneamento do Paraná - SANEPAR (SAPR4) investor relations material

Executive summary

• Net operating revenue rose 11.5% year-over-year to BRL 1,901.1 million, driven by tariff adjustments and increased water and sewage volumes, but a net loss of BRL 505.2 million was reported due to a significant regulatory liability provision related to a court-ordered IRPJ tax refund.

• Achieved strong operational growth in both water and sewage segments, with increases in measured and invoiced volumes year-over-year and sequentially from the previous quarter.

• The regulatory decision required 100% of the IRPJ gain to be allocated to users, impacting both results and the ability to distribute interest on equity for the period.
