  2. Governance Highlights

    Governance Highlights The Board is committed to creating long-term value for our shareholders while operating in an ethical, legal, environmentally sensitive and socially responsible manner. The Board follows sound governance practices, some of which are highlighted below. For more detail, see the “Corporate Governance” section of this proxy statement. ■Eleven of thirteen director nominees, 85%, are independent; our Executive Chairman and our President and Chief Executive Officer ("CEO") are the only management directors. ■All Board committees are composed exclusively of independent directors. ■We have implemented a proxy access provision, which makes it possible for a group of shareholders meeting certain criteria to nominate and include in the Company’s proxy materials a candidate for the Board. ■We have a Lead Independent Director, elected by the independent members of the Board. The Lead Independent Director maintains final approval authority over Board agendas, meeting materials and schedules. ■The Lead Independent Director is also available for consultation and direct communication with large shareholders. ■Independent directors met in executive sessions chaired by the Lead Independent Director at seven of the eight 2025 Board meetings. ■All of our directors are elected annually. ■We have a majority vote requirement for uncontested director elections. ■The Board and its committees conduct annual self-assessments. ■Each independent director who has served for one year or more undergoes an annual peer review. ■Our executive officers and directors are all subject to robust stock ownership requirements.

  4. Governance Highlights

    ■We have instituted anti-hedging policies applicable to all Company directors, officers and employees. ■We limit our directors who are employed by public companies to a total of not more than two public company boards and all other directors to a total of not more than four public company boards. Executive Compensation Highlights Our executive compensation programs are designed to be competitive with our peers, have a meaningful performance component linked to the achievement of short-term and long-term goals that align with our shareholders’ long-term interests and encourage executives to have an ownership interest in the Company. Our executives’ total compensation shows strong pay-for-performance alignment with growth in long-term shareholder value creation. See “Pay vs. Performance” tables and graphs beginning on page 60. The Company’s compensation programs are also designed to clearly align performance objectives for our Named Executive Officers with the interests of shareholders and with our system of priorities. Our performance measures are designed to help move our Company toward achieving these priorities. For more details, see our priorities alignment chart in the Compensation Discussion and Analysis Summary on page 37. Other highlights from our compensation program include: ■Our CEO received 69% of her 2025 total compensation in variable, at-risk incentives. For our other Named Executive Officers, the average percentage of variable, at-risk compensation was 69%. No at-risk compensation for our CEO or Named Executive Officers is reflected in customer rates. See more details on page 37. ■Our short-term and long-term performance metrics all tie directly to our stakeholder aspirations (see above). These are the same metrics that management uses to assess the Company’s progress toward our aspiration to be best in the world and best for the world. ■Our long-term plan awards include a mix of restricted stock and performance shares designed in part to encourage executive stock ownership. The Board’s Organization and Compensation Committee has not issued stock options since 2010. ■Our equity compensation plan forbids buyouts of “underwater” stock options. The Company has never bought or repriced “underwater” stock options. ■Our equity compensation plan generally requires a minimum one-year vesting period for equity awards. The Company’s typical practice is to require a three-year vesting period for equity awards and the Company has never issued equity awards with less than a one-year vesting period. ■Our Board has adopted a “clawback” policy that provides that, in the event of an accounting restatement due to material noncompliance with federal securities laws, the Company will seek to recover excess incentive-based compensation awarded to current or former executive officers during the three-year period preceding the restatement. ■Our executive Change-In-Control Severance Agreements do not include excise tax gross-ups. ■We do not provide for automatic vesting of equity issued under our Long-Term Incentive Plan upon a change in control of the Company, unless an acquiring or surviving entity fails to replace or affirm the existing equity awards with awards by the surviving company.

    Corporate Governance

  58. Governance Guidelines

    Governance Guidelines At DTE Energy, we are committed to operating in an ethical, legal, environmentally sensitive and socially responsible manner, while creating long-term value for our shareholders. The foundation of our governance practices begins at the top, with the DTE Energy Board of Directors Mission and Guidelines (“Governance Guidelines”). The Governance Guidelines set forth the practices the Board follows with respect to Board composition and selection, Board meetings, the performance evaluation and succession planning for DTE Energy’s Chief Executive Officer, Board committees, Board compensation and communicating with the Board, among other things. The Governance Guidelines are also intended to align the interests of directors and management with those of our shareholders. The following is a summary of the Governance Guidelines, along with other governance practices at DTE Energy.

  59. Election of Directors and Vacancies

    Election of Directors and Vacancies The Company has a declassified board of directors. Directors are elected annually for terms which expire upon election of their successor at the next year’s annual shareholder meeting. If a vacancy on the Board occurs between annual shareholder meetings, the vacancy may be filled by a majority vote of the directors then in office. The new director’s term will expire upon election of their successor at the next year’s annual shareholder meeting. Under the Governance Guidelines, the Corporate Governance Committee periodically assesses the skills, characteristics and composition of the Board, along with the need for expertise and other relevant factors as it deems appropriate. In light of these assessments, and in light of the standards set forth in the Governance Guidelines, the Corporate Governance Committee may seek candidates with specific qualifications and candidates who satisfy other requirements set by the Board. We believe our Board should be comprised of directors who have had high-level executive experience, have been directors on other boards and have been tested through economic downturns and crises. Industry experience, regional relationships and broad diversity of experience and backgrounds are also factors in Board nominee selection. We believe this type of composition enables the Board to oversee the management of the business and affairs of the Company effectively. Information about the skills, experiences and qualifications of our directors is included in their biographies beginning on page 11. The Corporate Governance Committee considers candidates who have been properly nominated by shareholders, as well as candidates who have been identified by Board members and Company personnel. In addition, the Corporate Governance Committee has engaged a search firm to assist in the search for candidates and nominees and to evaluate the nominees’ skills against the Board’s criteria. Based on its review of all candidates, the Corporate Governance Committee recommends a slate of director nominees for election at the annual meeting of shareholders. The slate of nominees may include both incumbent and new nominees. Potential candidates are reviewed and evaluated by the Corporate Governance Committee, and selected candidates are then interviewed by one or more Corporate Governance Committee members. An invitation to join the Board is extended by the Board itself, through the Chairman and the Chair of the Corporate Governance Committee. In conjunction with her appointment as President and Chief Executive Officer, Joi M. Harris was elected by the Board to serve for a term effective September 8, 2025 and expiring at the 2026 annual meeting. Under our Bylaws, a group of up to 20 shareholders owning 3% or more of the Company’s outstanding common stock continuously for at least three (3) years may nominate and include in the Company’s proxy materials a candidate for the Board of Directors (a Shareholder Nominee), provided that the shareholder(s) and the nominee satisfy the requirements specified in the Bylaws.

  60. Elements of Director Compensation

    Elements of Director Compensation Employee directors receive no payment for service as directors. The goal of our compensation policies for non-employee directors is to tie their compensation to your interests as shareholders. Accordingly, greater than 50% of a director’s annual compensation is in the form of equity-based compensation, including phantom shares of our common stock. Generally, the compensation program for non-employee directors is reviewed on an annual basis by the Corporate Governance Committee and the Board. This review includes a review of a comparative peer group of companies that is identical to the peer group used to review executive compensation (See “Executive Compensation—Compensation Discussion and Analysis” beginning on page 35). Based on its December 2025 review, the Board voted to increase director compensation effective January 1, 2026, as further described below.

  61. Elements of Director Compensation

    | Cash Compensation | | | Cash retainer | $125,000 annually | | Lead Independent Director retainer | $35,000 annually | | Committee chair retainer | $25,000 annually for Audit Committee Chair; $20,000 annually for Nuclear Review, Organization and Compensation, Corporate Governance, Finance, and Public Policy and Responsibility Committee Chairs | | New Member Orientation/Mentor Program | $1,250 and $750 quarterly for the New Member and Mentor, respectively, for the duration of the orientation | | Equity Compensation | | | Upon first election to the Board | 1,000 shares of restricted DTE Energy common stock, subject to a 3-year vesting period | | Annual equity compensation | A variable number of phantom shares of DTE Energy common stock valued at $175,000 annually, with the actual number of phantom shares to be granted each year determined based on the closing price of the Company’s common stock on the date of the annual meeting(1) |

  62. Elements of Director Compensation

    (1)Phantom shares of DTE Energy common stock are credited to each non-employee director’s account the date of the annual meeting each year. Phantom share accounts are also credited with dividend equivalents which are reinvested into additional phantom shares.

    Messrs. Brandon and Torgow elected to defer 100% of the fees detailed above into the DTE Energy Company Plan for Deferring the Payment of Directors’ Fees. (2)These amounts represent the dollar amounts of compensation cost for 2025 in accordance with ASC Topic 718 and, as such, include costs recognized in the financial statements with respect to phantom shares and shares of restricted stock granted. Because the phantom shares are 100% vested on the grant date, the ASC Topic 718 expense equals the grant date fair value as of May 8, 2025. The grant date fair value of $135.71 was the closing price of the Company stock on May 8, 2025. For all of the non-employee directors, this amount is $160,000 in phantom shares of DTE Energy stock granted on May 8, 2025, subject to a minimum one-year payment deferral. Based on the grant date fair value of $135.71, this equated to a grant of 1,180 phantom shares. For Ms. Santos, this amount also includes the value of 1,000 shares of restricted stock granted on February 6, 2025. For this award, the grant date fair value of $122.56 was the closing price on February 6, 2025.

    agreements require the Company to indemnify such individuals for certain liabilities to which they may become subject as a result of their affiliation with the Company. The Company, the directors and officers in their capacities as such are insured against liability for alleged wrongful acts (to the extent defined) under fifteen insurance policies providing aggregate coverage in the amount of $255 million. Security Ownership of Directors and Officers The following table sets forth information as of December 31, 2025, with respect to beneficial ownership of common stock, phantom stock, and performance shares for (i) each of our directors and nominees for director, (ii) our Executive Chairman (who served as Chief Executive Officer until September 7, 2025), President and Chief Executive Officer, Vice Chairman and Chief Financial Officer, and the three other highest paid executive officers (together, the “Named Executive Officers”), and (iii) all executive officers and directors as a group. Executive officers for this purpose are those individuals defined as executive officers under Rule 16a-1(f) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Unless otherwise indicated, each of the named individuals has sole voting and/or investment power over the shares identified. To our knowledge, no member of our management team or director was a beneficial owner of one percent or more of the outstanding shares of common stock as of December 31, 2025.

  76. Compensation and Peer Group Assessment

    Compensation and Peer Group Assessment Each component of executive compensation (see “Key Components of Executive Compensation” below) is compared, measured and evaluated against a peer group of companies. The O&C Committee approves the peer group and periodically reviews and updates the companies included in that group. The most recent peer group was approved by the O&C Committee in June 2024. That peer group consists of the companies listed below. Most of these companies, along with DTE Energy, participate in the same independent compensation surveys. The surveys provide data needed for accurate compensation comparisons. The peer group consists of utilities (including utility holding companies) and broad-based energy companies selected on the basis of revenues, financial strength, geographic location and availability of compensation information. The O&C Committee reviews the peer group data when making compensation decisions relating to the Named Executive Officers and the Company’s mix of compensation components. Management also retains an external consulting firm to conduct a market study covering compensation practices for similar positions in the peer group. The most recent market study was completed in October 2025 by Aon.

    Key Components of Executive Compensation The key components of the compensation program include the following: ■Base Salary ■Annual and Long-Term Incentives ■Retirement and Other Benefits ■Post-Termination Agreements (Severance and Change-In-Control)

  79. Key Components of Executive Compensation

    While the programs and pay levels reflect differences in job responsibilities, the structure of the compensation and benefits program is applied consistently to our Named Executive Officers, including the CEO. Differences in compensation between the CEO and the other Named Executive Officers are due, in part, to an analysis of peer group benchmark data, as well as differences in the responsibilities of each Named Executive Officer. We review each element of total compensation, both individually and on a combined basis, for each Named Executive Officer and make adjustments as appropriate based on these comparisons. The following is a more detailed discussion of the components of the Company’s executive compensation program:

  80. Annual and Long-Term Incentives

    Annual and Long-Term Incentives We have two primary types of incentives that reward executives for performance. The incentives are designed to tie compensation to performance and encourage executives to align their interests with those of the shareholders and customers of the Company. Our annual incentives allow us to reward executives with annual cash bonuses for performance against pre-established objectives based on work performed in the prior year. Our long-term incentives allow us to grant executives long-term equity incentives to encourage continued employment with DTE Energy, to accomplish pre-defined long-term performance objectives and to create shareholder alignment. We believe the current mix among base salary, annual incentives, and long-term incentives is appropriately set to provide market-competitive compensation when Company performance warrants. The mix is more heavily weighted toward incentive compensation at higher executive levels within DTE Energy. The interplay between the annual incentives and the long-term incentives provides a balance to motivate executives to achieve our business goals and objectives and to properly reward executives for the achievement of such goals and objectives. The Board has implemented a “clawback” policy enabling the Company to recover incentive-based compensation awarded to current or former executives. If the Company is required to prepare an accounting restatement due to material noncompliance with federal securities laws, the Company will seek to recover from any current or former executive any previously awarded incentive-based compensation (including awards under the Annual Incentive Plan and the Long-Term Incentive Plan) that is greater than the amount that would have been awarded based upon the restated financial results. This "clawback" would apply to incentive-based compensation during the three-year period preceding the date on which the Company is required to prepare an accounting restatement.

  81. Annual Incentives

    Annual Incentives The objective of the annual incentives is to compensate individuals yearly based on the achievement of specific annual goals and tie compensation to near-term performance. Annual incentive awards are paid to our executives under the DTE Energy Annual Incentive Plan (“Annual Incentive Plan”). The O&C Committee sets individual performance measures, metrics and targets for the Named Executive Officers for each year using the measures, metrics, targets and procedures described below, and the Named Executive Officer’s performance against those measures, metrics and targets is considered when the O&C Committee determines the officer’s annual incentive award under the Annual Incentive Plan for that year. Under the terms of the Annual Incentive Plan, participating executives and other select employees may receive annual cash awards based on performance compared against pre-established Company and business unit objectives. Objectives that management proposes are reviewed and approved or revised by the O&C Committee, with financial goal recommendations reviewed by the Board’s Finance Committee, usually within the first 90 days of the performance period. The objectives include performance measures in several categories that are critical to our success. When setting these objectives, management and the O&C Committee determine the elements of our business that require the focused attention of the executives. The weights, which can change from year to year, are determined based on the Company’s key priorities and areas of focus for the upcoming year. The final awards, if any, are paid after the O&C Committee approves the final results of each objective.

  82. Annual Incentives

    | 40 | DTE ENERGY 2026 PROXY STATEMENT |

  83. Annual Incentives

    The amount of an executive’s Annual Incentive Plan award is determined as follows: ■The executive’s most recent year-end base salary is multiplied by an Annual Incentive Plan target percentage to arrive at the target award. ■The overall performance payout percentage, which can range from 0% to 200%, is determined based on final results compared to threshold, target and maximum levels for each objective. ■The target award is then multiplied by the performance payout percentage to arrive at the calculated award. Each objective has a threshold, target and maximum level. The Company or relevant business unit must attain a minimum level of achievement for an objective before any compensation is payable with respect to that objective. The minimum established level of each objective will result in a payout of 25% of target and the maximum established for each level (or better) will result in a payout of 200% of target. The O&C Committee reserves the right to increase or decrease an executive's calculated Annual Incentive Plan award if, in its sole discretion, the O&C Committee determines an adjustment to be in the Company's best interests. The operating earnings per share and cash from operations measures were chosen as indicators of the Company’s financial strength. The customer satisfaction, employee engagement and safety performance and effectiveness measures were selected to make the Company more responsive to our customers’ needs and to make the Company a safer and better place to work. For Messrs. Norcia, Ruud and Lauer, and Mses. Harris and Chavez, the Utility Operating Excellence measures were chosen as representative of electric generation, electric distribution, and gas system reliability. For Mr. Paul, the DTE Electric Operating Excellence measures were chosen as representative of electric generation and distribution reliability. For Mr. Stiers, the DTE Vantage Business Development measures were chosen as representative of creating value while growing the business through new project development. For 2025, the performance objectives and the related weightings, thresholds, targets, maximums and results for calculating the Named Executive Officers’ annual incentive award amounts were as follows. For Messrs. Norcia, Ruud and Lauer, and Mses. Harris and Chavez:

  94. Long-Term Incentives

    Long-Term Incentives Long-term incentives provide the O&C Committee the ability to align programs that focus on our long-term performance over a three-year period, with the objective of aligning executives’ interests with those of our shareholders. Our principles for ownership of stock, discussed on page 48, ensure that the executives and other employees have a vested interest in the long-term financial health, management and success of the Company. The long-term incentives are awarded under the Long-Term Incentive Plan and reward executives and other employees with stock-based compensation. Named Executive Officers are eligible to receive restricted stock, performance shares, performance units, stock options or a combination of these awards. Since the creation of the Long-Term Incentive Plan, we have granted only performance shares, time-based restricted stock and nonqualified stock options. However, the O&C Committee has not granted stock options under

  96. Long-Term Incentives

    the Long-Term Incentive Plan since 2010. Executives receive long-term incentive grants based upon a target percentage of base salary. The targeted award levels for the Named Executive Officers for 2025 were as follows: Ms. Harris, 240% of base salary; Mr. Norcia, 625% of base salary; Mr. Ruud, 275% of base salary; Ms. Chavez, 190% of base salary; Mr. Lauer, 230% of base salary; Mr. Paul, 195% of base salary; and Mr. Stiers, 190% of base salary. In addition to the targeted award levels, the O&C Committee also considers previous years’ grants, career potential and retention in determining the final number of awards granted. The value of each element of these long-term incentive grants for 2025 was as follows:

  97. Long-Term Incentives

    | Performance Shares | Approximately 70% | | Restricted Stock | Approximately 30% |

  98. Long-Term Incentives

    This mix was designed to provide a balance of incentives to executives for creating long-term shareholder value through strong financial and operating performance and to align executive interests with shareholder interests. Performance Shares Granted in 2025: In 2025, performance shares represented approximately 70% of the overall long-term incentive grant value. Granting of performance shares allows us to tie long-term performance objectives with creating shareholder value. Performance shares entitle the executive to receive a specified number of shares, or a cash payment equal to the fair market value of the shares, or a combination of the two, in the plan administrator’s discretion, depending on the level of achievement of performance measures. The performance measurement period for the 2025 grants is January 1, 2025 through December 31, 2027. Payments earned under the 2025 grants and the related performance measures are described in footnote 2 to the “Grants of Plan-Based Awards” table on page 50. In the event a participant retires (age 65 or age 55 or older with at least 10 years of service), dies or becomes disabled, the participant or beneficiary retains the right to a pro-rated number of the performance shares that would otherwise have been payable based upon actual results for the entire performance period. In the event employment terminates for any other reason, the participant forfeits all rights to any outstanding performance shares. In June 2009, the O&C Committee decided that, beginning with the 2010 performance share grants, dividends or dividend equivalents would not be paid on unvested or unearned performance shares. During the period beginning on the date the performance shares are awarded and ending on the certification date of the performance objectives, the number of performance shares awarded will be increased, assuming full dividend reinvestment at the fair market value on the dividend payment date. The cumulative number of performance shares will be adjusted to determine the final payment based on the performance objectives as certified by the Committee. Performance Shares Paid in 2025: The performance shares granted in 2022 were paid in early 2025. The payout amounts were based upon performance measures, each of which was weighted to reflect its importance to the total calculation. The Company had to attain a minimum level for each measure before any compensation was payable with respect to that measure. The minimum established level of each measure would have resulted in a payout of 50% of target, with the exception of the cumulative operating earnings per share (COEPS) which is 25% of target, and an established maximum (or better) for each level would have resulted in a payout of 200% of target. The payout amount was based upon the following performance measures (and related weighting):

  103. For Mr. Stiers

    The measures in the above tables are defined below: Total Shareholder Return: Total DTE Energy shareholder return compared to 19 peer group companies (as defined below) based on the average share prices for December 2024 as compared to December 2021, including reinvestment of dividends. 3-year Cumulative Operating EPS 2022-2024: Cumulative total of reported earnings after operating adjustments divided by average shares outstanding. DTE Vantage Long-Range Earnings Growth: The measure of new and updated contracts completed between 2022 and 2024 that will generate earnings in 2026. The peer group for the performance shares granted under the Long-Term Incentive Plan, as approved by the O&C Committee, consists of the companies set forth below. These companies were selected because of a combination of the following: (1) their operations being largely regulated; (2) their size (based on market capitalization); and (3) their business strategies being similar to those of DTE Energy. In addition, companies that were in the process of being acquired were also eliminated. The O&C Committee reviews and approves this peer group annually.

  104. For Mr. Stiers

    | Alliant Energy Corporation | Eversource Energy | | American Electric Power | IDACorp Inc. | | Ameren Corporation | OGE Energy Corporation | | CenterPoint Energy, Inc. | Pinnacle West | | CMS Energy Corporation | Portland General Electric Company | | Consolidated Edison, Inc. | Southern Company | | Dominion Energy | TXNM Resources | | Duke Energy Corporation | WEC Energy Group | | Entergy Corporation | Xcel Energy, Inc. | | Evergy Inc. | |

  105. For Mr. Stiers

    Total shareholder return compared to the Peer Group is the primary measure because it reflects how well our Company has performed on total return to its shareholders relative to the total shareholder returns of similar companies. As displayed above, the 2025 payout levels approved by the O&C Committee were 89.76% for Mses. Harris and Chavez, Messrs. Norcia, Ruud, Lauer and Paul, and 144.88% for Mr. Stiers. Payouts for the NEOs under the Long-Term Incentive Plan for 2023 and 2024 ranged from 164% to 196%. For more details of the 2025 payouts see footnote 2 to the “Option Exercises and Stock Vested in 2025” table on page 51. Restricted Stock: The restricted stock grants are time-based and generally include a three-year vesting period. The granting of restricted stock allows us to grant executives long-term equity incentives to encourage continued employment. In 2025, restricted stock was granted, representing approximately 30% of the overall Long-Term Incentive Plan grant value, with the restriction period ending on February 5, 2028. The three-year vesting period focuses on long-term value creation and executive retention, and requires continued employment throughout the restriction period. In the event a participant retires (age 65 or age 55 or older with at least 10 years of service), dies or becomes disabled, the participant or beneficiary retains the right to a pro-rated number of restricted shares. In the event employment terminates for any other reason, the participant forfeits all rights to any outstanding restricted shares.

  107. Pension Benefits

    Pension Benefits Substantially all non-represented employees hired prior to 2012, including the majority of our Named Executive Officers, are eligible to participate in our tax-qualified pension plan, the DTE Energy Company Retirement Plan. Named Executive Officers are also eligible to participate in our nonqualified pension plans, the DTE Energy Company Supplemental Retirement Plan and the DTE Energy Company Executive Supplemental Retirement Plan.

  108. Executive Benefits

    Executive Benefits We provide executives with certain benefits generally not available to our other employees as a matter of competitive practice and as a retention tool. The O&C Committee periodically reviews the level of benefits provided to executives against a peer group to ensure they are reasonable and consistent with our overall compensation objectives. During 2025, we provided various benefits for a limited number of officers that included the following: ■Security driver for business: Based on our executive security policies and a security risk assessment by the Company’s chief security officer, the Board requires Ms. Harris to use a Company car and security driver while on Company business. The Company also provided Mr. Norcia with a Company car and security driver in 2025 during his tenure as Chief Executive Officer. ■Supplemental retirement benefits: Certain executives are eligible for both tax-qualified and non-qualified retirement benefits which are commonly offered by other employers in our peer group. For further description of the supplemental retirement benefits, see "Pension Benefits" beginning on page 52. ■Other benefits: Executives are allowed the limited use of corporate event tickets and the corporate condominium when available.

  109. Post-Termination Agreements

    Post-Termination Agreements We have entered into indemnification agreements and change-in-control agreements with each of the Named Executive Officers and certain other executives. Additionally, all officers of the Company participate in the DTE Energy Company Executive Severance Allowance Plan (the “Executive Severance Plan”). The indemnification agreements require that we indemnify these individuals for certain liabilities to which they may become subject as a result of their affiliation with the Company. The change-in-control agreements are intended to provide continuity of management in the event there is a change in control of the Company and to align executive and shareholder interests in support of corporate transactions. The Executive Severance Plan is intended to provide specific severance benefits to eligible executive employees whose employment with the Company is involuntarily terminated under specified circumstances. The important terms of, and the potential payments provided under, the change-in-control agreements and the Executive Severance Plan are described beginning on page 56.

  110. Nonqualified Deferred Compensation Programs

    Nonqualified Deferred Compensation Programs We have structured all of our nonqualified deferred compensation programs to comply with Internal Revenue Code Section 409A, as added by the American Jobs Creation Act of 2004. Internal Revenue Code Section 409A imposes additional tax penalties on our executive officers for certain types of nonqualified deferred compensation that are not in compliance with the form and timing of elections and distribution requirements of that section.

  111. Accounting Considerations

    Accounting Considerations Accounting considerations also play a role in our executive compensation program. Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“ASC Topic 718”) requires us to expense the fair value of our equity compensation over the vesting period, which reduces the amount of our reported profits. Because of this stock-based expensing and the impact of dilution to our shareholders, we closely monitor the number and the fair values of the outstanding equity awards.

  112. Summary Compensation Table

    Summary Compensation Table The table below summarizes the total compensation earned by each of the Named Executive Officers for the fiscal years ended December 31, 2023, December 31, 2024 and December 31, 2025.

  117. Summary Compensation Table

    (4)The long term incentive grants are valued in accordance with ASC Topic 718, based on the market price of our common stock on the grant date of the award, under the assumption that target performance will be achieved or the service requirement will be met and the awards will vest and will not be forfeited. The aggregate grant date fair value of equity grants is equal to the closing price of DTE Energy’s common stock on the date of grant. The number of awards granted and other information related to the 2025 grants are detailed in the “Grants of Plan-Based Awards” table on page 50. (5)The 2025 annual incentive amounts, shown in the Non-Equity Incentive Plan Compensation column, paid to the Named Executive Officers were calculated as described beginning on page 40. (6)The amounts in this column represent the aggregate change in the actuarial present values of each Named Executive Officer’s accumulated benefits under the DTE Energy Company Retirement Plan ("Qualified Plan"), the DTE Energy Company Supplemental Retirement Plan ("SRP"), and the DTE Energy Company Executive Supplemental Retirement Plan ("ESRP"). The measurement period for each of 2023, 2024, and 2025 was the calendar year. Amounts in this column change from year to year based on a number of different variables. The primary variable is the discount rate used for valuation purposes. The discount rates used for 2023 valuations were 5.00% for the Qualified Plan, 4.81% for the SRP, and 4.88% for the ESRP. The discount rates use for 2024 valuations were 5.65% for the Qualified Plan, 5.37% for the SRP, and 5.48% for the ESRP. The discount rates used for 2025 valuations were 5.43% for the Qualified Plan, 4.79% for the SRP, and 5.05% for the ESRP. These plans are described in more detail beginning on page 52. (7)The following table provides a breakdown of the 2025 amounts reported in this column:

  119. Summary Compensation Table

    * The matching contributions reflected in these two columns are predicated on the Named Executive Officers making contributions from eligible compensation to the DTE Energy Savings and Stock Ownership Plan (a tax-qualified 401(k) plan, the “Savings Plan”) and the Supplemental Savings Plan. The total combined Company matching contributions between the plans cannot exceed 6% of eligible compensation for each of the Named Executive Officers. Mr. Paul receives an additional 4% Company contribution, based on his eligible compensation, and it is not predicated on participant contributions. See "Deferred Compensation" on page 53 for full description of these benefits. ** The Supplemental Savings Plan provides for deferring compensation in excess of various Internal Revenue Code limits imposed on tax qualified plans, including the maximum employee pre-tax contribution limit and the compensation limit. Supplemental Savings Plan account balances are paid only in cash to the Named Executive Officer upon termination of employment. *** The value attributable to executive benefits for the Named Executive Officers. Executive benefits made available to certain of the Named Executive Officers during 2025 included such things as security services and limited personal use of corporate event tickets and the corporate condominium. In 2025, Ms. Harris received the services of a security driver while on Company business valued at $33,780. The Company also provided Mr. Norcia with a security driver in 2025 during his tenure as the Chief Executive Officer, valued at $42,709.

  138. Nonqualified Deferred Compensation

    (1)During 2025, all of the Named Executive Officers were participants in the Supplemental Savings Plan. These amounts represent the amounts deferred from eligible compensation into the Supplemental Savings Plan. (2)These amounts are the Company matching and other contributions to the Supplemental Savings Plan for 2025 and are included in the “Summary Compensation Table” on page 48 as “All Other Compensation.” (3)These earnings represent the total investment income earned in 2025 on the various investment alternatives that can be selected and directed by participants. The aggregate earnings are not reported as compensation in the Summary Compensation Table. The Supplemental Savings Plan — The percentage a participant may contribute to the Supplemental Savings Plan is the same as the pre-tax percentage that the participant elects to contribute to the Savings Plan. Company matching contributions mirror those under the Savings Plan. The investment options and restrictions are the same as under the Savings Plan, other than investment options available under the self-directed account feature of the Savings Plan. Participants are 100% vested at all times in the value of their contributions and Company matching contributions. We maintain bookkeeping accounts for participants in the Supplemental Savings Plan. In order to comply with Internal Revenue Code Section 409A, there are separate accounts for monies deferred for participant contributions and Company matching contributions on or after January 1, 2005. A participant’s benefit will be comprised of separate bookkeeping accounts evidencing his or her interest in each of the investment funds in which contributions and related Company contributions have been invested. No actual “contributions” are made to the funds themselves. Earnings or losses are calculated using the daily valuation methodology employed by the record keeper for each corresponding fund under the Savings Plan. When a participant terminates employment with the Company, the participant will be eligible to receive the full value of his or her Supplemental Savings Plan account, including all of his or her own contributions and all Company contributions, adjusted for investment earnings and losses. In the event of death, a lump sum distribution will be paid to the participant’s spouse or other designated beneficiary.

    Distributions from the Supplemental Savings Plan will be paid in cash. Distributions will be made in accordance with the participant’s distribution election. A participant may elect to take a lump sum distribution or annual payments over a period of not less than two years and not more than 15 years. Lump sums and the first annual installment payments from the participant’s pre-2005 account will be made no later than March 1 of the plan year following the year of termination. Subsequent annual installments will be made no later than March 1 of the installment period. In practice, lump sums, the first annual installment payment and subsequent annual installment payments are made in January. Lump sums and the first annual installment payments from the participant’s post-2004 account will be made as of January 1 of the plan year following the year of termination or next following the latest date to which the participant deferred the distribution under the terms of the plan; however, Named Executive Officers and certain other executives must wait a minimum of six months after termination prior to receiving a distribution from post-2004 balances. Subsequent annual installments will be made as of January 1 of the installment period.
