SUMMARY

The following summary highlights selected information contained elsewhere in this prospectus.

You should read the entire prospectus carefully, including the “Risk Factors” section and the other documents we refer to and incorporate by reference, in order to understand this offering fully. In particular, we incorporate important business and financial information into this prospectus by reference.

Pending any specific application, we may initially invest funds in short-term marketable securities or apply them to the reduction of short-term indebtedness.

TABLE OF CONTENTS

Unless the Board of Directors of the Company (the “Board”) determines otherwise, the Company will issue all shares of its capital stock in uncertificated form.

Class B Common Stock

Voting Rights

Each share of Class B common stock entitles the holder to one vote with respect to each matter presented to the Company’s stockholders on which the holders of Class B common stock are entitled to vote. Holders of shares of Class B common stock, Class C common stock and Class D common stock vote together as a single class on all matters presented to the Company’s stockholders for their vote or approval, except as otherwise required by applicable law or the listing requirements of any exchange on which shares of the Company’s common stock are listed. Holders of shares of Class B common stock do not have cumulative voting rights. Except in respect of matters relating to the election and removal of directors on the Board and as otherwise provided in the Certificate of Incorporation or required by law, all matters to be voted on by holders of shares of Class B common stock, Class C common stock and Class D common stock must be approved by a majority, on a combined basis, of such shares present in person or by proxy at the meeting and entitled to vote on the subject matter. In the case of election of directors, all matters to be voted on by the Company’s stockholders must be approved by a plurality of the votes entitled to be cast by all shares of common stock on a combined basis.

As of July 31, 2026, 41,678,637 shares of Class B common stock were held in the Voting Trust described below under “— Voting Trust Agreement”, and such shares will be voted by the Voting Trustee (as defined below) in accordance with the terms of the Voting Trust Agreement.

Dividend and Liquidation Rights

Holders of shares of Class B common stock do not have any right to receive dividends, other than dividends payable solely in shares of Class B common stock in the event of payment of a dividend in shares

TABLE OF CONTENTS

of common stock payable to holders of Class C common stock, or to receive a distribution upon the Company’s liquidation or winding up except for their right to receive payment for the par value of their shares of Class B common stock in connection with the Company’s liquidation.

Mandatory Redemption

In the event that, pursuant to the Exchange Agreement (as defined below), among the Company, Clearway LLC and CEG, the CEG Member (as defined below) exchanges Class B units of Clearway LLC for shares of Class C common stock, an equivalent number of outstanding shares of Class B common stock will be subject to mandatory redemption at a price per share equal to par value. Shares of Class B common stock so redeemed are automatically cancelled and are not available to be reissued.

Class C Common Stock

Voting Rights

Each share of Class C common stock entitles the holder to 1/100th of one vote with respect to each matter presented to the Company’s stockholders on which the holders of Class C common stock are entitled to vote. Holders of shares of Class B common stock, Class C common stock and Class D common stock vote together as a single class on all matters presented to the Company’s stockholders for their vote or approval, except as otherwise required by applicable law or the listing requirements of any exchange on which shares of the Company’s common stock are listed. Holders of shares of Class C common stock do not have cumulative voting rights. Except in respect of matters relating to the election and removal of directors on the Board and as otherwise provided in the Certificate of Incorporation or required by law, all matters to be voted on by holders of shares of Class B common stock, Class C common stock and Class D common stock must be approved by a majority, on a combined basis, of such shares present in person or by proxy at the meeting and entitled to vote on the subject matter. In the case of election of directors, all matters to be voted on by the Company’s stockholders must be approved by a plurality of the votes entitled to be cast by all shares of common stock on a combined basis.

Dividend Rights

Subject to preferences that may be applicable to any then outstanding preferred stock, the holders of the Company’s outstanding shares of Class C common stock are entitled to receive dividends, if any, as may be declared from time to time by the Board out of legally available funds. Dividends upon shares of Class C common stock may be declared by the Board at any regular or special meeting, and may be paid in cash, in property or in shares of capital stock. The holders of shares of Class C common stock will share ratably in all dividends as may be declared by the Board in respect of the outstanding common stock. Before payment of any dividend, there may be set aside out of any of the Company’s funds available for dividends, such sums as the Board deems proper as reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any of the Company’s property or for any proper purpose, and the Board may modify or abolish any such reserve. Furthermore, because the Company is a holding company, its ability to pay dividends on shares of Class C common stock is limited by restrictions on the ability of its subsidiaries to pay dividends or make other distributions to the Company, including restrictions under the terms of the agreements governing its indebtedness.

Liquidation Rights

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company’s affairs, holders of shares of Class C common stock would be entitled to share ratably in the Company’s assets that are legally available for distribution to stockholders after payment of its debts and other liabilities and the liquidation preference of any of the outstanding shares of preferred stock, subject only to the right of the holders of shares of Class B common stock and Class D common stock to receive payment for the par value of their shares in connection with the Company’s liquidation.

Other Rights

Holders of shares of the Company’s Class C common stock have no preemptive, conversion or other rights to subscribe for additional shares. All outstanding shares are, when issued, validly issued, fully paid

TABLE OF CONTENTS

and nonassessable. The rights, preferences and privileges of the holders of shares of Class C common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that the Company may designate and issue in the future.

Listing

The Class C common stock is listed on the NYSE under the symbol “CWEN.”

Transfer Agent and Registrar

The transfer agent and registrar for the Class C common stock is Computershare Shareowner Services, LLC.

Class D Common Stock

Voting Rights

Each share of Class D common stock entitles the holder to 1/100th of one vote with respect to each matter presented to the Company’s stockholders on which the holders of Class D common stock are entitled to vote. Holders of shares of Class B common stock, Class C common stock and Class D common stock vote together as a single class on all matters presented to the Company’s stockholders for their vote or approval, except as otherwise required by applicable law or the listing requirements of any exchange on which shares of the Company’s common stock are listed. Holders of shares of Class D common stock do not have cumulative voting rights. Except in respect of matters relating to the election and removal of directors on the Board and as otherwise provided in the Certificate of Incorporation or required by law, all matters to be voted on by holders of shares of Class B common stock, Class C common stock and Class D common stock must be approved by a majority, on a combined basis, of such shares present in person or by proxy at the meeting and entitled to vote on the subject matter. In the case of election of directors, all matters to be voted on by the Company’s stockholders must be approved by a plurality of the votes entitled to be cast by all shares of common stock on a combined basis.

Dividend and Liquidation Rights

Holders of shares of Class D common stock do not have any right to receive dividends, other than dividends payable solely in shares of Class D common stock in the event of payment of a dividend in shares of common stock payable to holders of Class C common stock, or to receive a distribution upon the Company’s liquidation or winding up except for their right to receive payment for the par value of their shares of Class D common stock in connection with the Company’s liquidation.

Mandatory Redemption

In the event that, pursuant to the Exchange Agreement, the CEG Member exchanges Class D units of Clearway LLC for shares of Class C common stock, an equivalent number of outstanding shares of Class D common stock will be subject to mandatory redemption at a price per share equal to par value. Shares of Class D common stock so redeemed are automatically cancelled and are not available to be reissued.

Authorized but Unissued Capital Stock

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of the NYSE, which would apply so long as the shares of Class C common stock remain listed on the NYSE, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or the then outstanding number of shares of Class C common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved common stock or preferred stock may be to enable the Board to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger,

TABLE OF CONTENTS

tender offer, proxy contest or otherwise, and thereby protect the continuity of the Company’s management and possibly deprive the stockholders of opportunities to sell their shares at prices higher than prevailing market prices.

Preferred Stock

Under the Certificate of Incorporation, the Company is authorized to issue up to 10,000,000 shares of preferred stock, par value $0.01 per share, none of which is issued and outstanding.

The Board is authorized to provide for the issuance of shares of preferred stock in one or more series and to fix the preferences, powers and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including the dividend rate, conversion rights, voting rights, redemption rights and liquidation preference and to fix the number of shares to be included in any such series without any further vote or action by the Company’s stockholders. Any preferred stock so issued may rank senior to the Company’s common stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up, or both. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of the Company without further action by the Company’s stockholders and may adversely affect the voting and other rights of the holders of common stock. The issuance of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of common stock, including the loss of voting control to others. At present, the Company has no plans to issue any preferred stock.

Voting Trust Agreement

CEG is a party to a Voting Trust Agreement (the “Voting Trust Agreement”) with Wilmington Trust, National Association, as the voting trustee thereunder (the “Voting Trustee”), pursuant to which, as of July 31, 2026, CEG has deposited into a voting trust (the “Voting Trust”) 41,678,637 shares of Class B common stock (the “Voting Trust Shares”). The following is a description of the material terms of the Voting Trust Agreement.

Proportionate Voting

Under the Voting Trust Agreement, on any matter presented to the Company’s stockholders for a vote, including the election or removal of directors and any corporate action (including certain proposed change of control transactions of the Company), the Voting Trustee is required to vote the Voting Trust Shares in the same proportion as the votes cast by all stockholders of the Company (including CEG with respect to any shares not held in the Voting Trust). For any matter subject to a vote of the holders of the same class or series of securities as any Voting Trust Shares (voting separately as a class and not together with one or more other classes or series of voting securities of the Company), the Voting Trustee is required to vote the Voting Trust Shares corresponding to such class or series in accordance with the written direction of CEG.

Dividends and Distributions

Upon the declaration by the Company of any dividend or distribution with respect to any Voting Trust Shares, the Voting Trustee will instruct the Company to cause such dividend or distribution to be paid or delivered directly to CEG as if CEG itself held the Voting Trust Shares; provided, that any dividend or distribution paid in the form of voting securities of the Company will be retained by the Voting Trustee in the Voting Trust and will be subject to all of the terms and conditions of the Voting Trust Agreement.

Transfers

Under the Voting Trust Agreement, CEG may not sell, transfer or otherwise dispose of any Voting Trust Shares, except in certain limited situations. Upon completion of any transfer of Voting Trust Shares permitted under the Voting Trust Agreement, such Voting Trust Shares generally will no longer be subject to the terms and conditions of the Voting Trust Agreement.

Share Issuances; Share Releases

Under the Voting Trust Agreement, the Voting Trustee is required to release from the Voting Trust to CEG (each such release, a “Share Release”) a specified number of Voting Trust Shares upon the occurrence

TABLE OF CONTENTS

of (i) any issuance by the Company of additional shares of Class C common stock or other voting securities (other than to CEG or a CEG Related Person (as defined in the Voting Trust Agreement)), (ii) any corporate action affecting the total relative voting power that CEG holds in the Company or (iii) any exchange by CEG of Class B units of Clearway LLC for shares of Class C common stock under the Exchange Agreement (a “B/C Exchange”). The number of shares to be released in any Share Release will be calculated in accordance with the Voting Trust Agreement and is intended to cause the total relative voting power that CEG holds in the Company as of immediately following such Share Release to equal the total relative voting power that CEG would have held as of immediately following such issuance, corporate action or B/C Exchange had (i) the conversion of each share of the Company’s former Class A common stock into one share of Class C common stock, which occurred on May 1, 2026, not occurred, (ii) the creation of the Voting Trust and the deposit of the initial Voting Trust Shares into the Voting Trust not occurred and (iii), in the case of a B/C Exchange, the Class B units of Clearway LLC subject to such B/C Exchange been exchanged for shares of Class A common stock rather than shares of Class C common stock (the “Hypothetical Baseline Voting Power”). Upon completion of any Share Release, any Voting Trust Shares so released from the Voting Trust will no longer be subject to the terms and conditions of the Voting Trust Agreement.

In addition, if, as a result of any B/C Exchange (or certain sales, transfers or other dispositions of shares of Class C common stock received in a B/C Exchange), CEG’s total relative voting power in the Company exceeds the Hypothetical Baseline Voting Power, CEG will be required to deposit into the Voting Trust additional shares of Class B common stock in an amount that would cause CEG’s total relative voting power as of immediately following such deposit to equal the Hypothetical Baseline Voting Power.

Term; Termination

The Voting Trust is irrevocable by CEG and will terminate only upon the earliest to occur of (i) an event constituting a change of control of the Company, (ii) the dissolution or liquidation of the Company or (iii) the time at which no Voting Trust Shares remain in the Voting Trust.

Corporate Opportunity

As permitted under the DGCL, in the Certificate of Incorporation, the Company renounced any interest or expectancy in, or any offer of an opportunity to participate in, specified business opportunities that are presented to the Company or one or more of its officers, directors or stockholders. In recognition that directors, officers and/or employees of CEG may serve as directors and/or officers of the Company, and CEG and its controlled affiliates, not including the Company (individually, an “Affiliated Company”, and collectively, the “Affiliated Companies”), may engage in similar activities or lines of business that the Company engages in, the Certificate of Incorporation provides for the allocation of certain corporate opportunities between the Company and the Affiliated Companies. Specifically, none of the Affiliated Companies will have any duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business that the Company engages in. In the event that a director or officer of any Affiliated Company who also is one of the Company’s directors or officers acquires knowledge of a potential transaction or matter which may be a corporate opportunity for any of the Affiliated Companies and the Company, the Company will not have any expectancy in such corporate opportunity, and the director or officer will not have any duty to present such corporate opportunity to the Company and may pursue or acquire such corporate opportunity for himself/herself or direct such opportunity to another person. A corporate opportunity that an officer or director of the Company who is also a director or officer of any of the Affiliated Companies acquires knowledge of will not belong to the Company unless the corporate opportunity at issue is expressly offered in writing to such person solely in his or her capacity as a director or officer of the Company. In addition, even if a business opportunity is presented to an officer or director of any of the Affiliated Companies, the following corporate opportunities will not belong to the Company: (1) those the Company is not financially able, contractually permitted or legally able to undertake; (2) those not in the Company’s line of business; (3) those of no practical advantage to the Company; and (4) those in which the Company has no interest or reasonable expectancy. Except with respect to the Company’s directors and/or officers who are also directors and/or officers of any of the Affiliated Companies, the corporate opportunity doctrine applies as construed pursuant to applicable Delaware laws, without limitation.

TABLE OF CONTENTS

Antitakeover Effects of Delaware Law and the Company’s Certificate of Incorporation and Bylaws

In addition to the disproportionate voting rights that CEG has as a result of its ownership of Class B common stock and Class D common stock, some provisions of Delaware law contain, and the Certificate of Incorporation and the Bylaws contain, a number of provisions which may have the effect of encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with the Board rather than pursue non-negotiated takeover attempts, which the Company believes may result in an improvement of the terms of any such acquisition in favor of the Company’s stockholders. However, these provisions also give the Board the power to discourage acquisitions that some stockholders may favor.

Undesignated Preferred Stock

The ability to authorize undesignated preferred stock will make it possible for the Board to issue preferred stock with superior voting, special approval, dividend or other rights or preferences on a discriminatory basis that could impede the success of any attempt to acquire the Company. These and other provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of the Company.

Meetings and Elections of Directors

Special Meetings of Stockholders. The Certificate of Incorporation provides that a special meeting of stockholders may be called only by the Board by a resolution adopted by the affirmative vote of a majority of the total number of directors then in office.

Elimination of Stockholder Action by Written Consent. The Certificate of Incorporation and the Bylaws provide that holders of the Company’s common stock cannot act by written consent in lieu of a meeting.

Vacancies. Any vacancy occurring on the Board and any newly created directorship may be filled only by a majority of the directors remaining in office (even if less than a quorum), subject to the rights of holders of any series of preferred stock.

Amendments

Amendments of Certificate of Incorporation. The provisions described above under “— Special Meetings of Stockholders,” “— Elimination of Stockholder Action by Written Consent” and “— Vacancies” may be amended only by the affirmative vote of holders of at least 662∕3% of the combined voting power of outstanding shares of the Company’s capital stock entitled to vote in the election of directors, voting together as a single class.

Amendment of Bylaws. The Board has the power to make, alter, amend, change or repeal the Bylaws or adopt new bylaws by the affirmative vote of a majority of the total number of directors then in office.

Notice Provisions Relating to Stockholder Proposals and Nominees

The Bylaws also impose some procedural requirements on stockholders who wish to make nominations in the election of directors or propose any other business to be brought before an annual or special meeting of stockholders.

Specifically, a stockholder may (i) bring a proposal before an annual meeting of stockholders, (ii) nominate a candidate for election to the Board at an annual meeting of stockholders, or (iii) nominate a candidate for election to the Board at a special meeting of stockholders that has been called for the purpose of electing directors, only if such stockholder delivers timely notice to the Company’s corporate secretary. The notice must be in writing and must include certain information and comply with the delivery requirements as set forth in the Bylaws.

To be timely, a stockholder’s notice must be received at the Company’s principal executive offices:

•

in the case of a nomination or other business in connection with an annual meeting of stockholders, not later than the close of business on the 90th day nor earlier than the close of business on the

TABLE OF CONTENTS

120th day prior to the first anniversary of the previous year’s annual meeting of stockholders; provided, however, that if the date of the annual meeting is advanced more than 30 days before or delayed more than 70 days after the first anniversary of the preceding year’s annual meeting, notice by the stockholder must be delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made by the Company;

•

in the case of a nomination in connection with a special meeting of stockholders, not earlier than the close of business on the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day before such special meeting or the 10th day following the day on which public announcement of the date of such meeting is first made by the Company.

With respect to special meetings of stockholders, the Bylaws provide that only such business shall be conducted as shall have been stated in the notice of the meeting.

Delaware Antitakeover Law

The Company has opted out of Section 203 of the DGCL. However, the Certificate of Incorporation provides that in the event CEG and its affiliates cease to beneficially own at least 5% of the total voting power of all the then outstanding shares of the Company’s capital stock, the Company will automatically become subject to Section 203 of the DGCL. Section 203 provides that, subject to certain exceptions specified in the law, a Delaware corporation shall not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder unless:

•

prior to such time, the Board approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock outstanding at the time the transaction commenced, excluding certain shares; or

•

at or subsequent to that time, the business combination is approved by the Board and by the affirmative vote of holders of at least 662∕3% of the outstanding voting stock that is not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years did own, 15% or more of the Company’s voting stock.

Under certain circumstances, Section 203 makes it more difficult for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year period. The provisions of Section 203 may encourage companies interested in acquiring the Company to negotiate in advance with the Board because the stockholder approval requirement would be avoided if the Board approves either the business combination or the transaction that results in the stockholder becoming an interested stockholder. These provisions also may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Amendments

Any amendments to the Certificate of Incorporation, subject to the rights of holders of the Company’s preferred stock, regarding the provisions thereof summarized under “— Corporate Opportunity” or “— Antitakeover Effects of Delaware Law and the Company’s Certificate of Incorporation and Bylaws” will require the affirmative vote of at least 662∕3% of the voting power of all shares of common stock then outstanding.

TABLE OF CONTENTS

Fifth Amended and Restated Limited Liability Company Agreement of Clearway LLC

The following is a description of the material terms of the Fifth Amended and Restated Limited Liability Company Agreement of Clearway LLC (the “Clearway LLC Agreement”). The following description is a summary and does not purport to be complete. It should be read in conjunction with, and is qualified in its entirety by reference to, the full text of the Clearway LLC Agreement.

Governance

The Company serves as the sole managing member of Clearway LLC. As such, the Company, and effectively the Board, controls the business and affairs of Clearway LLC and is responsible for the management of its business. No other member of Clearway LLC, in its capacity as such, has any authority or right to control the management of Clearway LLC or to bind it in connection with any matter. Any amendment, supplement or waiver of the Clearway LLC Agreement must be approved by a majority of the Company’s independent directors.

Voting and Economic Rights of Members

The limited liability company interests in Clearway LLC are denominated as “units,” which are comprised of three classes: Class C units, which may only be issued to the Company, as the sole managing member, and Class B units and Class D units, which may only be issued to CEG and held by CEG or its permitted assignees or permitted transferees (collectively, the “CEG Member”). Units of each of the three classes have equivalent economic and other rights, except that upon issuance, each holder of a Class B unit will also be issued a share of the Company’s Class B common stock and each holder of a Class D unit will also be issued a share of the Company’s Class D common stock. Each Class B unit and Class D unit is exchangeable for a share of the Company’s Class C common stock, subject to equitable adjustments for stock splits, stock dividends and reclassifications in accordance with the terms of the Exchange Agreement. When the CEG Member exchanges a Class B unit of Clearway LLC for a share of the Company’s Class C common stock, the Company will automatically redeem and cancel a corresponding share of Class B common stock, and the Class B unit will automatically convert into a Class C unit of Clearway LLC issued to the Company. When the CEG Member exchanges a Class D unit of Clearway LLC for a share of the Company’s Class C common stock, the Company will automatically redeem and cancel a corresponding share of the Company’s Class D common stock, and the Class D unit will automatically convert into a Class C unit of Clearway LLC issued to the Company. None of the units have any voting rights.

Net profits and net losses and distributions by Clearway LLC are allocated and made to holders of units in accordance with the respective number of membership units of Clearway LLC held. Clearway LLC will make distributions to the Company and CEG for the purpose of funding tax obligations in respect of income of Clearway LLC that is allocated to the members of Clearway LLC. However, Clearway LLC may not make any distributions to its members if doing so would violate any agreement to which it is then a party or any law then applicable to it, have the effect of rendering it insolvent or result in it having net capital lower than that required by applicable law. Additionally, because the Company’s operations are conducted primarily through Clearway Operating LLC, a wholly owned subsidiary of Clearway LLC, and Clearway Operating LLC’s Amended and Restated Credit Agreement restricts the ability of Clearway Operating LLC to make distributions to Clearway LLC, Clearway LLC may not have any funds available to make distributions to the Company and CEG (including with respect to tax obligations).

Coordination of the Company and Clearway LLC

At any time the Company issues a share of its Class C common stock for cash, the net proceeds therefrom will promptly be transferred to Clearway LLC and Clearway LLC will, at the Company’s election, either:

•

(i) transfer a newly issued Class C unit of Clearway LLC to the Company or (ii) purchase Class B units or Class D units from the CEG Member, which Class B units or Class D units, as applicable, will automatically be reclassified into Class C units; or

•

use a portion of the net proceeds to purchase a Class B unit or Class D unit of Clearway LLC from the CEG Member, which Class B unit or Class D unit will automatically convert into a Class C unit of Clearway LLC when transferred to the Company.

TABLE OF CONTENTS

In the event Clearway LLC purchases a Class B unit or a Class D unit of Clearway LLC from the CEG Member, the Company will concurrently redeem and cancel the corresponding share of its Class B common stock or Class D common stock, as applicable.

If the Company issues other classes or series of equity securities, Clearway LLC will issue, and the Company will use the net proceeds therefrom to purchase, an equal amount of units with designations, preferences and other rights and terms that are substantially the same as the Company’s newly-issued equity securities. Conversely, if the Company elects to redeem any shares of its Class C common stock (or its equity securities of other classes or series) for cash, Clearway LLC will, immediately prior to such redemption, redeem an equal number of Class C units (or its units of the corresponding classes or series) held by the Company upon the same terms and for the same price, as the shares of Class C common stock (or equity securities of such other classes or series) so redeemed.

Issuances and Transfer of Units

Class C units may only be issued to the Company, as the sole managing member of Clearway LLC, and are non-transferable except upon redemption by Clearway LLC. Class B units and Class D units may only be issued to the CEG Member. Class B units and Class D units may not be transferred without the Company’s consent, which may not be unreasonably withheld, conditioned or delayed, except the CEG Member may transfer Class B units or Class D units to any of its direct or indirect limited partners or other equityholders and to a permitted transferee (including an affiliate) without the Company’s consent. The CEG Member may not transfer any Class B units or Class D units to any person unless the CEG Member transfers an equal number of shares of the Company’s Class B common stock or Class D common stock, as applicable, to the same transferee.

Exchange Agreement

The Company is a party to a Third Amended and Restated Exchange Agreement with CEG and Clearway LLC (the “Exchange Agreement”), pursuant to which the CEG Member may, from time to time, cause Clearway LLC to (i) exchange its Class B units for shares of the Company’s Class C common stock or (ii) exchange its Class D units for shares of the Company’s Class C common stock, in each case, on a one-for-one basis, subject to adjustments for stock splits, stock dividends and reclassifications. The Exchange Agreement also provides that, subject to certain exceptions, the CEG Member does not have the right to cause Clearway LLC to exchange Class B units or Class D units if Clearway LLC determines that such exchange would be prohibited by law or regulation or would violate other agreements to which the Company may be subject, and the Company may impose additional restrictions on exchange that it determines necessary or advisable so that Clearway LLC is not treated as a “publicly traded partnership” for U.S. federal income tax purposes.

When the CEG Member exchanges a Class B unit of Clearway LLC for a share of the Company’s Class C common stock, the Company will automatically redeem and cancel a corresponding share of the Company’s Class B common stock and the Class B unit will automatically convert into a Class C unit when issued to the Company. Similarly, when the CEG Member exchanges a Class D unit of Clearway LLC for a share of the Company’s Class C common stock, the Company will automatically redeem and cancel a corresponding share of the Company’s Class D common stock and the Class D unit will automatically convert into a Class C unit when issued to the Company. As a result, when the CEG Member exchanges its Class B units or Class D units for shares of the Company’s Class C common stock, the Company’s interest in Clearway LLC will be correspondingly increased.

Additionally, when the CEG Member exchanges a Class B unit or Class D unit of Clearway LLC for shares of the Company’s Class C common stock, the CEG Member will pay the Company an equitable cash settlement on the applicable exchange date for the value of certain of the Company’s assets that are not held through Clearway LLC. The amount of any such payment will be calculated based on the net present value of the projected discounted cash flow of such assets, using a discount rate equal to the weighted average cost of capital for such assets, and the daily volume-weighted average closing price of the Company’s Class C common stock for the trailing 30 trading days ending on the second trading day prior to the applicable exchange date.

TABLE OF CONTENTS

The Company has reserved for issuance 84,099,892 shares of the Company’s Class C common stock, which is the aggregate number of shares of Class C common stock expected to be issued over time upon the exchange of all Class B units and Class D units of Clearway LLC currently outstanding.

Indemnification and Exculpation

To the extent permitted by applicable law, Clearway LLC will indemnify its and its affiliate’s members, partners, shareholders, directors, officers, fiduciaries and trustees, as well as the Company’s authorized officers and the Company’s other employees and agents, from and against any losses, liabilities, damages, costs, expenses, fees or penalties incurred in connection with serving in such capacities, provided that the acts or omissions of these indemnified persons are not the result of bad faith, fraud, willful misconduct or, in the case of a criminal matter, knowledge that the indemnified person’s conduct was unlawful.

Such indemnified persons will not be liable to Clearway LLC for damages incurred as a result of any acts or omissions of these persons, provided that the acts or omissions of these exculpated persons are not the result of bad faith, fraud, willful misconduct or, in the case of a criminal matter, knowledge that the indemnified person’s conduct was unlawful.

Amended and Restated Registration Rights Agreement

The Company entered into an amended and restated registration rights agreement with CEG (as successor-in-interest to NRG Energy, Inc.), pursuant to which CEG and its affiliates will be entitled to demand registration rights, including the right to demand that a shelf registration statement be filed, and “piggyback” registration rights, for shares of the Company’s Class C common stock that are issuable upon exchange of Class B units or Class D units of Clearway LLC that CEG owns.

We may sell securities from time to time in one or more transactions separately or in combination. We may sell the securities of or within any series to or through agents, underwriters, dealers, remarketing firms or other third parties or directly to one or more purchasers or through a combination of any of these methods. We may issue securities as a dividend or distribution. In some cases, we or dealers acting with us or on behalf of us may also purchase securities and reoffer them to the public. We may also offer and sell, or agree to deliver, securities pursuant to, or in connection with, any option agreement or other contractual arrangement.

Agents whom we designate may solicit offers to purchase the securities.

If we use an underwriter or underwriters, we will execute an underwriting agreement with the underwriter or underwriters at the time that we reach an agreement for the sale of the securities.

Any underwriter, agent or dealer that is a Financial Industry Regulatory Authority member is not permitted to sell securities in an offering to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

Unless otherwise specified in connection with a particular underwritten offering of securities, the underwriters will not be obligated to purchase offered securities unless specified conditions are satisfied, and if the underwriters do purchase any offered securities, they will purchase all offered securities.

We may enter into derivative or other hedging transactions involving the securities with third parties, or sell securities not covered by the prospectus to third parties in privately-negotiated transactions.

We may loan or pledge securities to third parties that in turn may sell the securities using this prospectus and the related prospectus supplement or, if we default in the case of a pledge, may offer and sell the securities from time to time using this prospectus and the related prospectus supplement.

An estimate of the aggregate expenses in connection with the issuance and distribution of the securities being offered will be included in the applicable prospectus supplement.

Item 15. Indemnification of Directors and Officers.

Delaware General Corporation Law; Certificate of Incorporation

Section 102(b)(7) of the DGCL allows a corporation to provide in its certificate of incorporation that a director of the corporation will not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except where the director breached the duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our Certificate of Incorporation provides for this limitation of liability.

Section 145 of the DGCL (“Section 145”) provides that a Delaware corporation may indemnify any person who was, is or is threatened to be made, party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful. A Delaware corporation may indemnify any persons who are, were or are a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person is or was a director, officer, employee or agent of another corporation or enterprise. The indemnity

II-1

TABLE OF CONTENTS

may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the corporation’s best interests, provided that no indemnification is permitted without judicial approval if the director, officer, employee or agent is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, or arising out of his or her status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145.

Bylaws

Our Bylaws provide that we must indemnify our directors and officers to the fullest extent permitted by the DGCL and must also pay expenses incurred in defending any such proceeding in advance of its final disposition upon delivery of an undertaking, by or on behalf of an indemnified person, to repay all amounts so advanced if it should be determined ultimately that such person is not entitled to be indemnified.

Indemnification Agreements

We have entered into indemnification agreements with certain of our executive officers and directors pursuant to which we agree to indemnify such persons against all expenses and liabilities incurred or paid by such person in connection with any proceeding arising from the fact that such person is or was an officer or director of our company, and to advance expenses as incurred by or on behalf of such person in connection therewith.

The indemnification rights set forth above are not exclusive of any other right which an indemnified person may have or hereafter acquire under any statute, provision of our Certificate of Incorporation, our Bylaws, agreement, vote of stockholders or disinterested directors or otherwise.

Insurance

We maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers.

Item 17. Undertakings.

(a)

The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

II-3

TABLE OF CONTENTS

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)

That, for the purpose of determining liability under the Securities Act to any purchaser:

(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)

That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered to sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

II-4

TABLE OF CONTENTS

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of such annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referred to in Item 15, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by such registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, such registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
