Fitch reaffirms 'AAA(bra)' Rating for Copel and its Subsidiaries

COPEL ("Company"), a company that generates, transmits, distributes and sells energy, informs its shareholders and the market in general that, on this date, the rating agency Fitch Ratings ("Fitch") reaffirmed the rating Long- Term 'AAA (bra)' of Copel and its wholly-owned subsidiaries Copel Geração e Transmissão ("Copel GeT") and Copel Distribuição ("Copel Dis"), the highest possible on the Fitch scale. At the same time, the outlook on the corporate ratings was kept stable.

The preservation of the 'AAA (bra)' rating mainly reflects the robust credit profile of the Copel group, the expectation of maintaining its strong financial profile and the consistent operating performance with its integrated operations in the energy sector, a characteristic that contributes to the dilution of operational and regulatory risks.

According to the Fitch report, the following fundamentals stand out:

1. Strong Business Profilejustified by the benefit of the diversification and relevance of its operating assets in the Brazilian electricity sector;
2. Robust Cash Generation, with emphasis on the generation business;
3. Distribution Efficiency Gains, mainly due to market growth above the national average, consistent cost control, investments in network modernization and losses below regulatory limits;
4. Manageable Hydrological Risk, given the best hydrological conditions and risk mitigation with conservative energy levels; and
5. Conservative Financial Leverage, less than 2.5x.

The Company highlights that the preservation of the rating at the top of the Fitch scale confirms its commitment to the sustainable strategic agenda of increasing efficiency in all businesses, disciplined capital allocation and advances in corporate governance.
