CUSIP No. 126153105

SCHEDULE 13D/A

Page 12 of 25 Pages

The name, business address, present principal occupation or employment and citizenship of each director and executive officer, as applicable, of each of the Reporting Persons (each of such directors and officers, a “Covered Person” and collectively, the “Covered Persons”) are set forth on Schedule A attached hereto, which is incorporated into this Item 2 by reference.

During the last five years, none of the Reporting Persons and, to the Reporting Persons’ knowledge, none of the Covered Persons, has been (i) convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 4. Purpose of Transaction.

Item 4 is hereby amended and restated in its entirety as set forth below:

The Reporting Persons view their investment in the Issuer as a strategic opportunity, the principal purpose of which is to diversify their business portfolio and take advantage of synergies between the Issuer and existing transmission assets of the Reporting Persons, and to thereby strengthen their position in the Brazilian power sector. The Reporting Persons intend to exercise control over the Issuer’s business and operations.

As the Issuer announced on its Form 6-K furnished to the SEC on December 18, 2019, the Issuer first issued American Depositary Shares (“ADSs”) and listed them on the New York Stock Exchange (“NYSE”) in September 2004, mainly to promote trading in the Common Shares and to raise the visibility of the Issuer’s brand in the United States. The Issuer subsequently found that the economic rationale for maintaining a listing on the NYSE had declined due in part to (i) increases in trading volume of Brazilian stocks on the B3 in Brazil by overseas investors due to the internationalization of the Brazilian financial and capital markets, as well as the narrowing of the gap between U.S. and Brazilian disclosure standards with respect to financial reporting; and (ii) a decreasing trend in recent years in the trading volume of the Issuer’s ADSs on the NYSE.

On December 19, 2019, the Issuer furnished a Form 6-K to the SEC including the minutes of its December 18, 2019 board of directors’ meeting approving the Issuer’s intention to (i) terminate the Issuer’s deposit agreement in connection with its ADS program, (ii) delist the Issuer’s ADSs from the NYSE, and (iii) terminate the Issuer’s registration with the SEC. Following the termination of the Issuer’s deposit agreement, on January 28, 2020, the NYSE suspended trading in the Issuer’s ADSs and filed a Form 25 with the SEC to permanently remove the Issuer’s ADSs from listing on the NYSE. This removal became effective on February 10, 2020, when the Issuer furnished a Form 6-K to the SEC announcing the removal of its ADSs from listing and registration on the NYSE.

On May 8, 2020, the Issuer filed a post-effective amendment to its registration statement on Form F-3 to deregister unsold securities from registration, and the Issuer disclosed that it intends to file a Form 15F with the SEC to deregister and terminate its reporting obligations under the Exchange Act of 1934, as amended, or the Exchange Act, once the Issuer meets the criteria for terminating its reporting obligations under the Exchange Act.

In this context, the Reporting Persons seek to cause the Issuer to deregister as a public company in the United States, while the Issuer will maintain the listing of the Common Shares on the B3, and the Issuer will continue to be subject to applicable disclosure requirements under Brazilian laws and regulations.

The Reporting Persons review their investments on a continuing basis. Depending on overall market conditions, performance and prospects of the Issuer, subsequent developments affecting the Issuer, other investment opportunities available to the Reporting Persons, the market prices of the Common Shares and other investment considerations, the Reporting Persons may hold, vote, acquire or dispose of or otherwise deal with securities of the Issuer, or suggest or take a position with respect to the management, operations or capital structure of the Issuer, including by taking, proposing or supporting one or more of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, in addition to those plans and actions described above.

CUSIP No. 126153105

SCHEDULE 13D/A

Page 13 of 25 Pages

Also, consistent with the investment purpose, the Reporting Persons may engage in communications with the Issuer’s shareholders, management, stockholders and third parties regarding the corporate governance, business operations, strategy or future plans (including proposed corporate transactions of a significant nature) of the Issuer, including any plans or proposals regarding the same.

Any of the foregoing actions may be effected from at any time or from time to time, subject to applicable law. Except as disclosed above, the Reporting Persons have no plans or proposals of the type referred to in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

Item 5 is hereby amended and restated in its entirety as set forth below:

(a)-(b) The responses of the Reporting Persons to rows (7) through (13) of the cover pages and Items 2, 3, 4 and 6 of this Schedule 13D are incorporated into this Item 5 by reference. The Reporting Persons are in the aggregate beneficial owners of 964,521,902 Common Shares (or approximately 83.7% of the 1,152,254,440 Common Shares stated to be outstanding as of March 31, 2020 in the 2019 20-F) and (i) all of the Reporting Persons except for ESC have shared power to vote or direct the vote of, and shared power to dispose of or direct the disposition of, all of such Common Shares and (ii) ESC has shared power to vote or direct the vote of, and shared power to dispose of or direct the disposition of, 234,086,204 of such Common Shares (or approximately 20.3% of such Common Shares).

To the Reporting Persons’ knowledge, none of the Covered Persons directly owns any Common Shares; however, because each Covered Person is a director or executive officer of one or more Reporting Persons, each Covered Person may be deemed to be the beneficial owner of the Common Shares beneficially owned by the Reporting Person(s) for which they each serve as director or executive officer. Each of the Covered Persons hereby disclaims beneficial ownership of any Common Shares and the filing of this Schedule 13D shall not be construed as an admission that any such Covered Person is the beneficial owner of any securities covered by this Schedule 13D or that any such Covered Person is a member of a “group” for Section 13(d) purposes.

(c) None of the Reporting Persons nor, to their knowledge, any of the Covered Persons, has effected any transactions in Common Shares during the past 60 days.

(d) Except as disclosed in this Schedule 13D, no other person is known to the Reporting Persons to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Shares covered by this statement on Schedule 13D.

(e) Not applicable.
