None of the previously issued shares of Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock remained outstanding prior to filing the Statements of Resolutions.

Effective upon filing, the Statements of Resolutions deleted all references to the Series A Preferred Stock, the Series B Preferred Stock and the Series C Preferred Stock contained in CenterPoint Energy’s Restated Articles of Incorporation.

The shares that were designated to such series were returned to the status of authorized but unissued shares of preferred stock, par value $0.01 per share, of CenterPoint Energy, without designation as to series.

Copies of the Series A Statement of Resolutions, the Series B Statement of Resolutions and the Series C Statement of Resolutions are filed as Exhibits 3(m), 3(n) and 3(o), respectively, and are incorporated herein by reference.

Effective February 16, 2024, the Board amended and restated CenterPoint Energy’s bylaws (the Bylaws).

The Bylaws include, among other things, the following changes:

• revise procedures and disclosure for the nomination of directors and the submission of proposals for consideration at meetings of the shareholders of CenterPoint Energy, including, among other things, (x) consolidating the advance notice provisions applicable to all proposals (i.e., director nominations, proposals to amend CenterPoint Energy’s bylaws, proposals to remove directors and all other proposals (other than “proxy access” nominations and shareholder proposals made pursuant to Section 14a-8 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”)) into a single section and (y) adding a requirement that a shareholder seeking to nominate director(s) at an annual meeting deliver to CenterPoint Energy reasonable evidence that it has complied with the requirements of Rule 14a-19 of the Exchange Act within eight business days of the meeting;

• clarify that for the applicability of the majority voting standard for uncontested elections of directors, an election remains “contested” (and the plurality voting standard applies) even if the Board determines that a shareholder’s nomination notice does not comply with the advance notice bylaws;

• adopt a forum selection bylaw to provide that the U.S.

federal district courts shall be the exclusive forum for the resolution of claims under the Securities Act of 1933, as amended;

• make certain administrative, modernizing, clarifying and conforming changes, including (x) making updates to reflect amendments to the Texas Business Organizations Code, as amended, (y) expressly providing that meetings of shareholders may be held in whole or in part by means of remote communications in accordance with applicable law and (z) adopting gender-neutral terms when referring to particular positions, offices or title holders, including the adoption of the title Chair in place of Chairman.

The foregoing description of the terms of the Bylaws does not purport to be complete and is subject to, and qualified in its entirety by, reference to the complete text of the Bylaws.

The Bylaws, along with a copy marked to show changes from the prior version, are included as Exhibits 3(h) and 3(i), respectively, to this Annual Report on Form 10-K and incorporated by reference herein.

Compensatory Arrangements of Certain Officers (CenterPoint Energy)

On February 15, 2024, the Compensation Committee approved new forms of award agreement under CenterPoint Energy’s LTIP for restricted stock unit awards and performance unit awards.

The newly approved forms of award agreement for officers and director employees revise and simplify the retirement provisions by adopting a single retirement provision that provides the opportunity for full vesting if the award was granted prior to the calendar year of the participant’s retirement or pro-rata vesting if the award was granted in the calendar year of the participants retirement, in all cases subject to achievement of the relevant performance metrics.

To be eligible for such retirement vesting, the participant must (i) be at least 55 years old with a sum of age and years of service of 65 or greater, (ii) provide at least three months’ written notice (or reasonable advance written notice for officers subject to Section 16 of the Exchange Act) of retirement, and (iii) provide a comprehensive transition plan.

In addition, for officers subject to Section 16 of the Exchange Act, eligibility for retirement vesting is subject to approval by the Compensation Committee.

In addition, the newly approved forms of award agreement revised the non-solicitation and confidentiality provisions to reflect changes in the law.

The description of the forms of award agreement are qualified in their entirety by reference to the full text of the respective form award agreement, which are included as Exhibits 10(cc)(13), 10(cc)(14), and 10(cc)(15).

On February 15, 2024, the Compensation Committee also approved 3-year ratable vesting for annual restricted stock unit awards under which one third (1/3) of the underlying units vest and are payable as of the first three anniversaries of the grant date, subject to the participant’s continued employment and achievement of the applicable performance goal.

The Compensation Committee also approved a price-to-earnings (P/E) modifier to performance share unit awards under the Company’s LTIP based on total shareholder return.

Under the P/E modifier, if CenterPoint Energy’s P/E ratio ranks in the top quartile of CenterPoint Energy’s peer group, a P/E modifier will apply that provides for a minimum 75% payout level for the award regardless of the level of total shareholder return performance achieved.

This vesting schedule and the P/E modifier does not apply to previously granted awards.
