CESP - COMPANHIA ENERGÉTICA DE SÃO PAULO ("CESP" or the "Company"), pursuant to article 157, section 4, of Law 6,404/76 ("Corporation Law") and CVM Resolution 44/21, hereby informs the following, in continuity with the Material Facts disclosed by the Company on October 18th, 2021, October 21st, 2021, November 24th, 2021, December 10th, 2021, January 3rd, 2022, and January 10th, 2022, concerning the proposed reorganization which aims to consolidate into a single entity certain energy assets owned by the Company's indirect controlling shareholders, Votorantim S.A. ("VSA") and Canada Pension Plan Investment Board ("CPPIB" and, together with VSA, the "Controlling Shareholders", and the "Reorganization", respectively), including the investment in the Company.

As informed by the Material Fact disclosed by the Company on October 21st, 2021, the Company appointed the Special Independent Committee, in compliance with CVM Guidance Opinion No. 35 (the "Independent Committee"), in order to negotiate with its controlling shareholder's management, VTRM Energia Participações S.A. ("VTRM"), the transaction involving a merger of all of the shares issued by the Company by VTRM, excluding the shares that, on the effectiveness date of the merger of shares ("Closing Date"), (a) are held by VTRM, (b) are in CESP's treasury, or (c) have been subject to the exercise of the right of withdrawal by CESP's shareholders ("Merger of Shares"). Also, as informed by the Material Fact disclosed by the Company on January 10th, 2022, the Independent Committee submitted to the Company's Board of Directors its recommendation for the proposed exchange ratio of the shares issued by CESP for shares issued by VTRM related to the Merger of Shares ("Exchange Ratio"), which was unanimously approved by the Company's Board of Directors on the meeting held on January 7th, 2022 ("BDM 01.07.22").

Afterwards, on a meeting held on January 21, 2022, the Company's Board of Directors approved, among other matters, (i) the execution, between the Company and its controlling shareholder, VTRM, of the Private Instrument of Protocol and Justification of the Merger of Shares (Instrumento Particular de Protocolo e Justificação de Incorporação de Ações da CESP - Companhia Energética de São Paulo pela VTRM Energia Participações S.A.) ("Merger Protocol"), which sets forth, among other matters, the terms and conditions for the Merger of Shares; and (ii) the calling of the extraordinary shareholders meeting of the Company to be held, at first call, on February 15th, 2022 to

resolve, among other matters, upon the Merger Protocol, the exit by the Company of the Nível 1 listing segment of B3 S.A. - Brasil, Bolsa, Balcão ("B3") and other matters related to the Merger of Shares ("ESM").

It is worth noting that, according to the Merger Protocol, in order to optimize the market value of VTRM shares, stimulating liquidity and the least impact of price fluctuations, after the VTRM Transaction (as defined below) and before the completion of the Merger of Shares, a grouping of VTRM shares will be carried out, so that 4,253509378 VTRM shares will be grouped into 1 share, without changing VTRM's capital stock ("Reverse Stock Split").

Considering the above, by force of the Reverse Stock Split, the Exchange Ratio approved on the BDM 01.07.22 will be adjusted proportionately, as described in Exhibit I of this Material Fact, being all of such adjustments already reflected on the Merger Protocol for all purposes.

Still, pursuant to the Merger Protocol, upon the completion of the Merger of Shares, the Company's shareholders will receive, in consideration for the merged shares issued by the Company held by them, new common and redeemable preferred shares issued by VTRM ("VTRM Redeemable Preferred Shares"). The VTRM Redeemable Preferred Shares will be immediately and compulsorily redeemed, in consideration for a cash payment to shareholders ("Redemption").

Pursuant to the Merger Protocol, the Merger of Shares and the Redemption are interdependent and linked events, the effectiveness and consummation of which will be subject to applicable corporate approvals and the implementation of certain conditions precedent ("Conditions Precedent"), including, among other usual conditions for this type of operation: (i) the listing of VTRM as a Category "A" publicly held company with the Comissão de Valores Mobiliários ("CVM"); (ii) the listing of VTRM on B3 and the admission of its shares to be traded at Novo Mercado, subject to the Redemption; (iii) the completion of certain steps of the Reorganization, including the transfer to VTRM, by VSA and CPPIB, of certain assets and cash ("VTRM Transaction"); and (iv) the approval of the Merger of Shares by the debenture holders of the 11th and 12th debenture issuance of the Company, pursuant to the terms and conditions provided in the respective deeds, or the redemption of the mentioned debentures, pursuant to the applicable terms and conditions set out in the respective deeds.

If approved by the ESM, the Merger of Shares will be conditioned upon and shall only be effective upon the satisfaction (or waiver, as applicable) of the Conditions Precedent, to be verified and declared by the Company and VTRM's Board of Directors.

Upon the completion of the Merger of Shares, the Company shall become a wholly- owned subsidiary of VTRM, and the totality of the issued shares will be held by VTRM, without any modification in the Company's capital stock.

In compliance with the provisions of CVM Instruction No. 565/2015 ("ICVM 565"), Exhibit I describes the main terms and conditions of the Merger of Shares.

The information and documents related to the calling of the ESM, including the Management Proposal, the Merger Protocol and the opinion of the Fiscal Council regarding the Merger of Shares, will be timely disclosed to the shareholders, under the terms and deadlines of the applicable legislation, and made available in the electronic pages of CVM (https://www.gov.br/cvm), of B3 (http://www.b3.com.br) and of the Company (https://ri.cesp.com.br/).

The parties understand that the Brazilian energy sector has become increasingly dynamic and that current trends, based on the energy transition, the growth of competitiveness and addition of renewable sources, and the market opening process, with the consequent migration of customers from the captive market to the free energy market, provide important avenues for growth and new opportunities.

In this context, the parties understand that the Reorganization, including the Merger of Shares, will enable VTRM to become one of the main publicly listed companies in the Brazilian electricity sector, and one of the largest energy traders in the country.

As a result, it is believed that the Company's shareholders will have access to new and clear growth opportunities.
