For 2022, Jason Wells, Scott Doyle, Monica Karuturi, and Gregory Knight.

(3)

Compensation “actually paid” for each fiscal year is the total compensation reported in the Summary Compensation table for that year adjusted by the following amounts. The amounts for the

non-PEO

NEOs are provided as averages. For purposes of these adjustments, PSUs based on a TSR performance objective, whether vested, unvested, or forfeited, were valued using Monte Carlo simulation. PSUs based on a

non-TSR

performance objective, whether vested, unvested, or forfeited, were valued using the closing trading price for CenterPoint Energy common stock on the applicable valuation date and assuming projected achievement as of the end of the fiscal year.

(4)	Cumulative TSR is determined for the measurement period starting 12/31/2019 and ending on 12/31/2022, 12/31/2021, and 12/31/2020, respectively. Peer group TSR is weighted based on market capitalization as of 12/31/2019 and is based on PHLX Utility Sector Index (UTY) TSR sourced from FactSet.

(5)	Amounts shown are consolidated net income reported pursuant to GAAP in our annual report on Form 10-K.

(6)

The company-selected measure represents what the company believes is the most important financial performance measure (other than company TSR or net income) used to link company performance and the compensation actually paid to our named executive officers. The company-selected measure is Adjusted EPS. An EPS financial measure aligns with our commitment to return value to investors through earnings and dividends paid. Adjusted EPS is a

non-GAAP

metric which includes net income from electric and natural gas segments, as well as after tax corporate and other operating income and corporate overhead and adjusted for certain factors to reflect what we consider to be our fundamental business performance. Adjusted EPS excludes, among other items, earnings and losses from the change of value of ZENS and related securities, income and expenses related to ownership and disposal of certain midstream units, a corresponding amount of debt related to the units and allocation of associated corporate overhead, gain and impact including expenses associated with certain mergers and divestitures and other potential impact, such as changes in accounting standards, impairments or unusual items, which could have a material impact on GAAP reported results. For a full list of adjustments and reconciliation of Adjusted GAAP to consolidated income (loss) available to common shareholders and diluted EPS, the nearest GAAP metrics, please see Appendix A.
