2017 Financial Statements

Companhia Paranaense de Energia – COPEL, a company that generates, transmits, distributes and sells power, with shares listed at B3 (CPLE3, CPLE5, CPLE6), NYSE (ELPVY, ELP) and LATIBEX (XCOP), pursuant to the provisions of CVM Instruction No. 358/02, hereby announces to its shareholders and to the market in general, complementing its Notices to the Market No. 26/17 and 29/17, released by the Company on November 14 and 24, 2017, respectively, that even though it continues to make progresses in the necessary evaluations of accounting value and classification of a certain investment made by Araucária TPP, indirect subsidiary of the Company (“UEGA”), as already disclosed in Note 1 of the Quarterly Earnings Release (QER) for the quarter ended on September 30, 2017, which was released on November 29, 2017 (“3Q17 QER”), the details of these evaluations extended the work schedule, thus the 2017 financial statements were not concluded, therefore, the Management’s Report (“MR”) and the Financial Statements (“FS”) for the year ended on December 31, 2017 will not be filed at CVM within the legal term.

As reported in the 3Q17 QER, the Company hired specialists and carried out an independent internal investigation to evaluate the investment made by UEGA, which is still under progress. The Company’s Management reinforces that it believes that the impacts on the FS are restricted to UEGA, but with eventual effects on the consolidated FS. Nevertheless, until the conclusion of the works, it is not possible to reach a conclusion on the need for any adjustments to the FS.

In view of the foregoing, the Company issued today a new Calendar of Corporate Events, including the new dates scheduled (i) to file the FS and the MR, (ii) to hold the 2017 earnings call conference, and (iii) to hold the Annual Shareholders’ Meeting, among other related events. The Calendar of Corporate Events can be accessed here (http://ir.copel.com/enu/9560/Events%20Calendar%202018.pdf).

Copel will continue to use its best efforts to conclude the preparation of the FS as soon as possible, endorsing its background of compliance with the rules on periodic and occasional information.

Curitiba, March 23, 2018.
