NOTICE OF ANNUAL MEETING
April 12, 2023
To the Holders of Our Common Stock:
The 2023 annual meeting of stockholders (the “Annual Meeting”) of NiSource Inc., a Delaware corporation, will be conducted in a virtual format only via live audio webcast on Tuesday, May 23, 2023, at 10:00 a.m. Central Time at www.virtualshareholdermeeting.com/NI2023, for the following purposes:

■ | To elect twelve directors named in the proxy statement to hold office until the next annual stockholders’ meeting and until their respective successors have been elected or appointed and qualified;

■ | To approve named executive officer compensation on an advisory basis;

■ | To approve the frequency of future advisory votes on named executive officer compensation on an advisory basis;

■ | To ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2023;

■ | To approve an amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of common stock;

■ | To consider a stockholder proposal requesting that our Board of Directors adopt a policy requiring separation of the roles of Chairman of the Board and Chief Executive Officer; and

■ | To transact such other business as may properly come before the Annual Meeting and any adjournment or postponement thereof.

The Annual Meeting will be conducted in a virtual format only to provide access to all of our stockholders regardless of geographic location. There is no in-person meeting for you to attend. A virtual-only meeting enables increased shareholder attendance and participation, improves efficiency, and reduces costs. We designed the format of the Annual Meeting to ensure that our stockholders who attend the Annual Meeting will be afforded similar rights and opportunities to participate as they would at an in-person meeting.
All stockholders of record as of the close of business on March 29, 2023, are eligible to vote at the Annual Meeting and any adjournment or postponement thereof.
This year, we are pleased to help protect the environment and save costs by using the “Notice and Access” method of delivery. Instead of receiving paper copies of our proxy materials in the mail, many shareholders will receive a Notice of Internet Availability of Proxy Materials (the “Notice”).
Your vote is very important. You may vote during the Annual Meeting by following the instructions available on the meeting website, but if you are not able to attend virtually, please submit your vote as soon as possible as instructed in the Notice, proxy card or voting instruction form. You can vote via mail, telephone or the Internet. Whether or not you plan on attending the Annual Meeting, we urge you to vote and submit your proxy in advance of the Annual Meeting using one of these methods.

EXECUTIVE COMPENSATION HIGHLIGHTS
We have designed our executive compensation program to meet our business objectives using various compensation elements intended to drive both long-term and short-term performance. We believe that a significant portion of total compensation should consist of at-risk performance-based compensation. Our executive compensation practices include the following, each of which the Compensation and Human Capital Committee believes reinforces our executive compensation policy and objectives.
See “Compensation Discussion and Analysis (CD&A)” and “2022 Executive Compensation” for more information on our executive compensation program.
ENVIRONMENTAL AND SOCIAL HIGHLIGHTS
On November 7, 2022, we announced a goal of net-zero greenhouse gas emissions by 2040 covering both Scope 1 and Scope 2 emissions (“Net-Zero Goal”). Our Net-Zero Goal builds on greenhouse gas emission reductions achieved to-date and demonstrates that continued execution of our long-term business plan will drive further greenhouse gas emission reductions. We remain on track to achieve previously announced interim greenhouse gas emission reduction targets by reducing fugitive methane emissions from main and service lines by 50 percent from 2005 levels by 2025 and reducing Scope 1 greenhouse gas emissions from company-wide operations by 90 percent from 2005 levels by 2023. We plan to achieve our Net-Zero Goal primarily through continuation and enhancement of existing programs, such as the retirement of coal-fired electric generation, increased sourcing of renewable energy, methane reductions from priority pipeline replacement, traditional leak detection and repair, and deployment of advanced leak detection and repair. Additionally, we are active in several efforts to accelerate the development and demonstration of lower-carbon energy technologies and resources, such as hydrogen and renewable natural gas, to enable affordable pathways to economy-wide decarbonization.

Holders of shares of common stock as of the close of business on March 29, 2023, are entitled to notice of and to vote at the Annual Meeting and any adjournment thereof. As of March 29, 2023, 412,982,639 shares of common stock were issued and outstanding. Each share of common stock outstanding on that date is entitled to one vote on each matter presented at the Annual Meeting.
Voting Your Proxy
If you are a “stockholder of record” (that is, if your shares of common stock are registered directly in your name on the Company’s records), you may vote your shares by proxy in advance of the Annual Meeting using any of the following methods:

■ | Telephoning the toll-free number listed on the proxy card;

You must follow the voting instructions in order to have your shares of common stock voted.
2023 Proxy Statement|5

TABLE OF CONTENTS

PROXY STATEMENT
Discretionary Voting by Brokers and “Broker Non-Votes”
If your shares are held in street name and you do not provide the Broker with instructions as to how to vote such shares, your Broker will only be able to vote your shares at its discretion on certain “routine” matters as permitted by New York Stock Exchange (“NYSE”) rules. The proposal to ratify the appointment of our independent registered public accounting firm and the proposal to amend our Certificate of Incorporation to increase the number of authorized shares of common stock are considered routine matters and, accordingly, at the Annual Meeting, Brokers will only have discretionary authority to vote your shares regarding Proposal No. 4, the ratification of the appointment of Deloitte as our independent registered public accounting firm for 2023, and Proposal No. 5, the amendment to our Certificate of Incorporation to increase the number of authorized shares of common stock. A “broker non-vote” occurs when a Broker holding shares for a beneficial owner does not have discretionary authority to vote the shares and has not received instructions from the beneficial owner as to how the beneficial owner would like the shares to be voted. Brokers will not have discretionary authority to vote your shares with respect to the other proposals to be presented at the Annual Meeting. Therefore, it is important that you instruct your Broker or other nominee how to vote your shares. If Brokers exercise their discretionary voting authority on Proposal No. 4 or Proposal No. 5, such shares will be considered present at the Annual Meeting for quorum purposes and broker non-votes will occur as to each of the other proposals presented at the Annual Meeting, which are considered “non-routine.”
Voting Shares Held in Our 401(k) Plan
If you hold your shares of common stock in our 401(k) Plan, those shares are held in the name of Fidelity Management Trust Company (“Fidelity”), the administrator of the 401(k) Plan. You will receive a proxy card that includes the number of shares of our common stock held in the 401(k) Plan. You should instruct Fidelity how to vote your shares by completing and returning the proxy card or by voting your shares by Internet or by telephone, as detailed above under “Voting Your Proxy.” If you do not instruct Fidelity how to vote your shares, or if you sign the proxy card with no further instructions as to how to vote your shares, Fidelity will vote your shares in the same proportion as the shares for which it receives instructions from all other participants to the extent permitted under applicable law. To allow enough time for Fidelity to vote your shares in accordance with your direction, your voting instructions must be received by Fidelity no later than 11:59 p.m. Eastern Time on May 18, 2023.
Attending and Voting During the Virtual Annual Meeting
Format of Meeting. The Annual Meeting will be conducted in a virtual format only to provide access to all our stockholders regardless of geographic location. There is no in-person meeting for you to attend. We designed the format of the Annual Meeting to ensure that our stockholders who attend the Annual Meeting will be afforded similar rights and opportunities to participate as they would at an in-person meeting.
Attending the Meeting. You are entitled to attend and participate in the Annual Meeting if you were a stockholder of record as of the close of business on March 29, 2023, the record date, or hold a legal proxy for the Annual Meeting provided by your Broker as described below. To attend and participate in the Annual Meeting, visit www.virtualshareholdermeeting.com/NI2023 and enter your 16-digit control number, which can be found on your proxy card, voting instruction form or email you received with your proxy materials. If your shares are held by a Broker and you do not have a control number, please contact your Broker as soon as possible so that you can be provided with a control number.
Voting During the Meeting. You may vote during the Annual Meeting by following the instructions available on the meeting website during the meeting. If your shares are held in street name by a Broker, then, to be able to vote at the Annual Meeting, you must obtain an executed legal proxy from the Broker indicating that you were the beneficial owner of the shares on March 29, 2023, the record date for voting, and that the Broker is giving you its proxy to vote the shares. If your shares are held in the 401(k) Plan, you will not be able to vote your shares at the Annual Meeting. Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting by one of the methods described above under “Voting Your Proxy.” Votes cast at the Annual Meeting or represented by proxy at the Annual Meeting will be tabulated by the inspector of election.
Technical Assistance. The Annual Meeting will begin promptly at 10:00 a.m. Central Time. We encourage you to access the Annual Meeting approximately 15 minutes in advance to allow ample time for you to log in to the meeting and test your

computer audio system. We recommend that you carefully review the above procedures needed to gain admission in advance. Technicians will be ready to assist you with any technical difficulties you may have accessing the virtual meeting. If you encounter any difficulties accessing the virtual meeting during check-in or during the meeting, please call the technical support number that will be posted on the meeting login page at www.virtualshareholdermeeting.com/NI2023.
Submitting Questions During the Meeting. As part of the Annual Meeting, we will hold a question and answer session during which we intend to answer questions submitted during the meeting that are relevant to the purposes of the meeting and the Company’s business in accordance with the Annual Meeting procedures posted on the meeting website, as time permits. Questions may be submitted by stockholders that have used 16-digit control numbers to enter the meeting at www.virtualshareholdermeeting.com/NI2023. Questions and answers may be grouped by topic and substantially similar questions may be grouped and answered once.
Revoking Your Proxy
You may revoke your proxy at any time before a vote is taken or the authority granted is otherwise exercised. To revoke a proxy, you may send a letter to our Corporate Secretary (which must be received before a vote is taken) indicating that you want to revoke your proxy, or you can supersede your initial proxy by submitting a duly executed proxy bearing a later date, voting by telephone or through the Internet on a later date, or attending the virtual Annual Meeting and voting during the meeting. Attending the virtual Annual Meeting will not in and of itself revoke a proxy.
Quorum for the Meeting
A quorum of stockholders is necessary to take action at the Annual Meeting. A majority of the outstanding shares of common stock, present during the virtual Annual Meeting or represented by proxy, will constitute a quorum at the Annual Meeting. The inspectors of election appointed for the Annual Meeting will determine whether a quorum is present. Abstentions are counted for purposes of determining whether a quorum is present. As explained above under “Discretionary Voting by Brokers and ‘Broker Non-Votes’,” if Brokers exercise their discretionary voting authority on Proposal No. 4 or Proposal No. 5, such shares will be considered present at the meeting for quorum purposes and broker non-votes will occur as to each of the other proposals presented at the Annual Meeting.
2023 Proxy Statement|7

TABLE OF CONTENTS

PROPOSAL 1 – ELECTION OF DIRECTORS
At the recommendation of the Environmental, Social, Nominating & Governance (“ESN&G”) Committee, the Board has nominated the persons listed below to serve as directors, each for a one-year term, beginning at the Annual Meeting on May 23, 2023, and expiring at the 2024 annual meeting of our stockholders (the “2024 Annual Meeting”) and until their successors are duly elected or appointed and qualified. The nominees include eleven independent directors, as defined in the applicable rules of the NYSE, and our President and CEO. The Board does not anticipate that any of the nominees will be unable to serve, but if any nominee is unable to serve, the proxies will be voted in accordance with the judgment of the person or persons voting the proxies. All of the nominees currently serve on the Board. Set forth below is information regarding all of our nominees (each of whom has consented to being named in the Proxy Statement and to serving, if elected).
Vote Required
To be elected, a nominee must receive more votes cast in favor of his or her election than against election. Abstentions by those present or represented by proxy will not be counted as a vote cast either “for” or “against” with respect to the election of directors and, therefore, will have no effect on the outcome. Brokers will not have discretionary authority to vote on the election of directors. Accordingly, there could be broker non-votes which will have no effect on the vote.
Under our Corporate Governance Guidelines, each nominee will tender a conditional resignation prior to the Annual Meeting, effective only if both (a) the votes “against” a nominee’s election exceed the votes “for” election (a “failed re-election”) and (b) such resignation is subsequently accepted by the Board. Any failed re-election will be referred to the ESN&G Committee, which will make a recommendation to the Board as to whether to accept or reject the resignation. The Board will decide and publicly disclose its decision, the rationale for the decision and the directors who participated in the process within 90 days after the election. The Board expects the director who has not been re-elected to abstain from participating in the ESN&G Committee or Board discussion or vote regarding whether to accept his or her resignation offer. A director who has had a failed re-election may participate in discussions or votes with respect to other directors who have had a failed re-election.

Board Leadership Structure
Our Corporate Governance Guidelines state that we should remain free to configure leadership of the Board in the way that best serves our interests at the time and, accordingly, the Board has no fixed policy with respect to combining or separating the offices of Chair and CEO. If the Chair is not an independent director, an independent Lead Director will be chosen annually by the Board, taking into account the recommendation of the ESN&G Committee. The Chair or, if the Chair is not an independent director, the Lead Director, will be the presiding director of executive sessions of the Board. To promote open discussion among the non-management directors, the Board schedules regular executive sessions at meetings of the Board and each of its committees.
Since late 2006, the offices of Chair and CEO of the Company have been held by different individuals, with the Chair being an independent director.

The Board periodically reviews the structure and the division of responsibilities between the role of independent Chair and CEO.

Board Oversight of Risk
The Board takes an active role in monitoring and assessing our strategic, compliance, operational and financial risks, as well as cybersecurity risks. The Board has oversight over risks related to Environmental, Social and Governance (“ESG”) strategy and governance, including assuring that ESG risks and opportunities are directly tied to our business strategy and understanding how we are measuring progress toward goals as part of our ESG strategy.

TABLE OF CONTENTS

CORPORATE GOVERNANCE
Our Risk Management Committee, which consists of members of our senior management, is responsible for oversight of our risk management process. Senior management regularly provides reports on our risks to the Board, the Audit Committee and the other Board committees that oversee the applicable risks. Additionally, the Audit Committee discusses with management and the independent registered public accounting firm the effect of regulatory and accounting initiatives on our financial statements and is responsible for review and evaluation of our major risk exposures, including cybersecurity and supplier risks, and the steps management has taken to monitor and control such exposures.
The Compensation and Human Capital Committee, the Safety, Operations, Regulatory and Policy (“SORP”) Committee, the Finance Committee and the ESN&G Committee are each charged with overseeing the risks associated with their respective areas of responsibility. For example, the Compensation and Human Capital Committee oversees risks related to executive compensation and human capital management matters, including incentive compensation, succession planning, diversity, employee engagement, culture and talent management. The SORP Committee oversees risks related to safety and operations. The Finance Committee oversees risks related to capital management and allocation and investor relations. The ESN&G Committee oversees risks related to environmental, social, sustainability and climate change matters, public company governance, CEO succession planning, political spending and stockholder engagement. For more information regarding the oversight responsibilities of the Board Committees, see the descriptions of the committees below.
Generally, at each Board meeting, the chairs of each committee provide a report to the Board on any key items and risks discussed at the respective committee meetings. In addition, the Board regularly discusses the Company’s short-, medium-, and long-term strategy and risks. Shorter term risks and related matters are generally discussed at meetings of the Board and applicable committee on a regular and recurring basis, whereas longer term risks are discussed at least annually and as appropriate throughout the course of the year. Our Board or applicable committee receives information from external advisors and others, including the Company’s independent auditors, legal counsel, compensation consultant, and financial advisors, to advise on key risks and other issues relevant to the Company.
Succession Planning
Our management team performs succession planning quarterly for officer-level and critical roles to ensure that we develop and sustain a strong bench of talent capable of performing at the highest levels. Not only is talent identified, but potential paths of development are discussed to ensure that employees have an opportunity to build their skills and are well prepared for future roles. We maintain formal succession plans for our CEO and key executive officers. The succession plan for our CEO is reviewed by the ESN&G Committee and the succession plans for executive officers (other than the CEO) and critical roles are reviewed by the Compensation and Human Capital Committee annually or more frequently as needed.
Meetings and Committees of the Board
The Board met 12 times during 2022. Each incumbent director attended at least 75% of the total number of meetings of the Board and of the committees of the Board on which he or she served, and in each case, during the periods that he or she served. Pursuant to our Corporate Governance Guidelines, directors are expected to attend all Board meetings to spend the time needed to discharge their responsibilities as directors and to attend the annual meeting of stockholders.

Members of the Board have direct access to all of our employees, outside advisors and independent registered public accounting firm.
The Board has established six standing committees to assist the Board in carrying out its duties: the Audit Committee, the Compensation and Human Capital Committee, the ESN&G Committee, the Executive Committee, the Finance Committee and the SORP Committee.

The ESN&G Committee, with the assistance of the independent compensation consultant, annually reviews the amount and composition of non-employee director compensation. Please see the discussion under the heading “2022 Director Compensation” for a description of the compensation we provide to our non-employee directors. The ESN&G Committee also leads the processes set forth below.
Director Selection Process.The ESN&G Committee identifies and screens candidates for director and makes its recommendations for director to the Board. At times the Board may establish an ad hoc search committee to assist the ESN&G Committee in this process. Additionally, the ESN&G Committee has the authority to retain a search firm to help it identify director candidates to the extent it deems necessary or appropriate. Any search firm that is engaged will include women and minority candidates in the pool from which the ESN&G Committee selects director candidates. In considering candidates for director, the ESN&G Committee considers the skills, expertise, experience and qualifications that will best complement the overall mix of skills and expertise of the Board in view of the strategy of, and the risks and opportunities that we face, as well as each candidate’s relevant business, academic and industry experience, professional background, age, current employment, community service, other board service and other factors. In addition, the ESN&G Committee takes into account the racial, ethnic and gender diversity of the Board and actively seeks minority and female candidates.
The ESN&G Committee seeks to identify and recommend candidates with a reputation for, and record of, integrity and good business judgment who have experience in positions with a high degree of responsibility and are leaders in the organizations with which they are affiliated; are effective in working in complex collegial settings; are free from conflicts of interest that could interfere with a director’s duties to us and our stockholders; and are willing and able to make the necessary commitment of time and attention required for effective service on the Board, including limiting their service on other boards to a reasonable number. The ESN&G Committee also takes into account the candidate’s level of financial literacy. The ESN&G Committee monitors the mix of skills and experience of the directors in order to assess whether the Board has the necessary tools to perform its oversight function effectively. The ESN&G Committee also assesses the diversity of the Board as a part of its annual self-assessment process as described in more detail below. The ESN&G Committee will consider nominees for directors recommended by stockholders and will use the same criteria to evaluate candidates proposed by stockholders as it uses to evaluate the candidates identified by the Board.
The Board has determined that all of the members of the ESN&G Committee are independent as defined under the applicable NYSE rules and our Corporate Governance Guidelines.
For information on how to nominate a person for election as a director at the 2024 Annual Meeting, please see the discussion under the heading “Stockholder Proposals and Nominations for 2024 Annual Meeting.”
Evaluation Processes.The Board recognizes that a robust and constructive performance evaluation process is an essential component of Board effectiveness. As such, the Board conducts (a) director and (b) board and committee annual performance evaluations that are intended to determine whether the Board, each of its committees, and individual Board members are functioning effectively and to provide them with an opportunity to reflect upon and improve processes and effectiveness. The ESN&G Committee oversees these evaluation processes. Annually at its meeting in March, the ESN&G Committee initiates the board and committee self-evaluation process and approves the form of written evaluation questionnaires that are distributed to each director for completion. The written evaluation questionnaires are updated each year as necessary to reflect changes identified in the prior year, any committee charter changes and any suggestions from the directors. The questionnaires solicit feedback on Board composition, Board

meeting mechanics, including information received, core responsibilities, relationship with management, committee functioning and other relevant matters. Annually at its meeting in October, the ESN&G Committee initiates the director evaluation process and approves the form of written evaluation questionnaires that are distributed to each director for completion. Similar to the board and committee evaluations, the director evaluation questionnaires are reviewed and updated annually, as needed to reflect changes identified since the prior year, any committee charter changes and any suggestions from the directors. In addition, on an ongoing basis, the ESN&G Chair meets with each director individually to solicit feedback with respect to both the full Board and any committee on which the director serves, in addition to individual director performance and Board dynamics. Our Board utilizes the results of these evaluations in making decisions on Board agendas, Board structure, committee responsibilities and agendas, information presented to the Board, and continued service of individual directors on the Board. This information is then shared with the Board, and appropriate actions or changes are then identified.
Director Education.At the Company’s expense, all directors are encouraged to periodically attend director continuing education programs offered by various organizations. The Company also maintains an orientation program that consists of written materials, oral presentations, and site visits. In addition to orientation, we maintain an internal director education program where corporate and industry information is disseminated through various mediums, including presentations and written materials, webinars and seminars and site visits.
Retirement Age; No Term Limits.The Board periodically evaluates the performance and qualifications of individual directors in connection with the nomination process, including the appropriate time for retirement of directors. However, no director after having attained the age of 72 years will be nominated for re-election to the Board unless the Board determines that the nomination is in the best interests of the Company. In addition, although the ESN&G
Committee will consider length of service in recommending candidates for re-election, the Board does not believe that adopting a set term limit for directors serves our interests. Such limits may result in the loss of contributions from directors who have been able to develop, over a period of time, increasing insight into our operations and our strategic direction. The ESN&G Committee reviews these policies as part of its annual governance review and will consider modifications to these policies as deemed necessary and in our best interests and the best interests of our stockholders.
Director Compensation.This section describes compensation for our non-employee directors. To attract and retain highly qualified candidates to serve on the Board, we provide a combination of cash and equity awards. Our non-employee director compensation is reviewed annually by our ESN&G Committee with the assistance of Meridian Compensation Partners, LLC (“Meridian”), the Compensation and Human Capital Committee’s independent compensation consultant. A full-time employee who serves as a director does not receive any additional compensation for service on the Board.
For 2022, each non-employee director received an annual retainer of $275,000, consisting of $110,000 in cash and an award of restricted stock units (“RSUs”) valued at $165,000 at the time of grant. The cash retainer is paid in arrears in four equal installments at the end of each calendar quarter.
RSUs are awarded annually, and the number of RSUs is determined by dividing the value of the grant by the closing price of our common stock on the grant date. The RSUs granted following the Company’s 2022, 2021 and 2020 annual meetings of stockholders were granted under the NiSource Inc. 2020 Omnibus Incentive Plan (“2020 Omnibus Plan”), while RSU awards granted prior to the 2020 annual meeting of stockholders were granted under the NiSource Inc. 2010 Omnibus Incentive Plan (“2010 Omnibus Plan”). Unless the non-employee director elects to defer receipt of his or her RSU awards, the RSUs are payable in shares of our common stock on the earlier to occur of: (a) the last day of the director’s annual term for which the RSUs are awarded; or (b) the date that the director separates from the Board due to a “Change-in-Control” (as defined in the 2020 Omnibus Plan or 2010 Omnibus Plan (the “Omnibus Plan”), as applicable); provided, however, that any director that commences service on the Board after the start of an annual term will vest on the first anniversary of the initial grant. The RSU awards also contain pro-rata vesting provisions for a separation from the Board due to retirement, death or disability. RSUs accrue dividends prior to settlement in shares of our common stock. If a non-employee director elects to defer receipt of his or her RSUs, then such deferred stock units will be paid in shares of our common stock upon the non-employee director’s separation from the Board or such other date selected by the non-employee director.

TABLE OF CONTENTS

CORPORATE GOVERNANCE
Each non-employee director who serves as chair of a Board committee receives compensation for the additional responsibilities associated with such service. The 2022 committee chair fees were $20,000 for each of the standing committees. The Chair of the Board received additional annual compensation of $160,000 for his role. These fees are paid in cash in arrears in four equal installments and are prorated in the case of partial year service.
All Other Compensation.The compensation included under the column “All Other Compensation” in the 2022 Director Compensation Table below consists of matching contributions made by the NiSource Charitable Foundation (the “Foundation”).
Director Stock Ownership.The Board maintains stock ownership requirements for directors that are included in our Corporate Governance Guidelines. Within five years of becoming a non-employee director, each non-employee director is required to hold an amount of our stock with a value equal to five times the annual cash retainer paid to directors. Company stock that counts towards satisfaction of this requirement includes shares purchased on the open market, awards of restricted stock or RSUs, and shares beneficially owned in a trust or by a spouse or other immediate family member residing in the same household. All of the non-employee director nominees are in compliance with the stock ownership guideline or are within the five-year transition period included in the Corporate Governance Guidelines.
Each director has a significant portion of his or her compensation directly aligned with long-term stockholder value. Approximately sixty percent (60%) of a non-employee director’s 2022 annual retainer (valued as of the time of award and excluding committee retainers) consisted of RSUs, which are converted into common stock when vested and distributed to the director.

Components of 2022 Compensation
The mix of key elements of compensation (expressed as a proportion of total compensation) awarded to our chief executive officer reflects a significant portion of the total target being both performance-based and at-risk, which is consistent with our pay for performance philosophy.
For 2022, the Compensation and Human Capital Committee approved a mix of pay that balanced short-term and long-term incentives and focused the efforts of our NEOs on the achievement of both short-term business objectives and long-term strategic objectives. The majority of our NEOs’ total target direct compensation was in the form of equity awards to further align the interests of our NEOs with those of our stockholders. For more information, see “Our Executive Compensation Program.”
Highlights of our Compensation Practices
We review all elements of our executive compensation program and, in addition to designing a program to comply with required rules, we adopt current best practices where deemed appropriate for our business and shareholders.

Executive Compensation Decision Making
Our Objectives
The key design priorities of our 2022 executive compensation program were to:

​ | Provide a competitive total target direct compensation package that enables us to: | ​ | ​ | ​ | ​
​ | ■ | ​ | ​ | Attract and retain talented executives | ​ | ​ | ■ | ​ | ​ | Provide market competitive compensation opportunities | ​
​ | ■ | ​ | ​ | Motivate and reward executives for sustaining high performance | ​ | ​ | ■ | ​ | ​ | Ensure significant portions of pay opportunity are aligned with our strategy and shareholder value creation | ​

The Compensation and Human Capital Committee believes that our executive compensation program is thoughtfully and effectively constructed to fulfill our compensation objectives and reward effective leadership decisions that support the creation of value for all our stakeholders: customers, employees, communities, and stockholders.
Compensation
Annually, the Compensation and Human Capital Committee is responsible for reviewing and approving (or, in the case of our CEO, recommending to the independent members of the Board for approval) each element of total target direct compensation for our executive officers including our NEOs. NEO compensation decisions for Messrs. Vegas and Anderson were made in January 2022 at which time the Compensation and Human Capital Committee consisted of Messrs. Butler, Jesanis and Yates and Ms. Henretta. NEO compensation decisions made for Ms. Birmingham and Mr. Jefferson were made at the time of hire for each of them, at which time the Compensation and Human Capital Committee consisted of Messrs. Butler, Bunting, Johnson, and Ms. Henretta. All of the executive compensation decisions made by the Compensation and Human Capital Committee were based primarily on the following factors (“Pay Factors”):

■ | Corporate performance and attainment of our established business and financial goals (Messrs. Vegas and Anderson)

■ | Competitiveness of our compensation program (and each NEO’s total target direct compensation and each element of compensation) based upon competitive market data

■ | Executive officer’s/NEO’s position, experience, role, responsibilities, and performance relative to achievement of business goals

■ | Internal pay equity

■ | Mix of variable at-risk versus fixed pay

■ | Mix of cash versus equity pay

In addition, the Compensation and Human Capital Committee considered compensation recommendations from our then-CEO, Mr. Hamrock, reflecting his assessment of each NEO’s performance (other than his own performance). The Compensation and Human Capital Committee separately evaluated potential pay alternatives prepared by Meridian to develop its compensation recommendation for review and approval by the independent members of the Board for Mr. Yates. Mr. Yates was not involved in making recommendations with respect to his compensation.
2022 Say-on-Pay Results
When making decisions about our executive compensation program, the Compensation and Human Capital Committee considers the stockholders’ views of such matters. In 2022, approximately 95% of the votes cast by our investors were voted in favor of our say-on-pay proposal at our 2022 annual meeting of stockholders. In fact, over the last five years, we have received an average of 95% of the votes cast by our investors in favor of our say-on-pay proposal. No changes were made to the design of our executive compensation program in response to the 2022 say-on-pay advisory vote. The Compensation and Human Capital Committee did, however, make some limited changes to the 2022 STI and LTI programs, as described in further detail under “2022 Short-Term Incentive (STI) Program” and “2022 Long-Term Incentive (LTI) Program” below under “Executive Compensation Elements.”

Our Executive Compensation Program
Components of 2022 Executive Compensation Program
The primary components of our 2022 executive compensation program were base salary, the short-term incentive program, and the long-term incentive program.
2022 Executive Compensation Pay Mix and Total Target Direct Compensation
We set 2022 total target direct compensation (base salary, annual short-term performance-based cash incentives, and long-term incentive awards) to be competitive with the compensation paid to similarly positioned executives at companies within our compensation peer group (the “Comparator Group”). We do not, however, manage pay to a stipulated percentile of the Comparator Group companies.
The following charts show the mix of 2022 total target direct compensation for our CEO, the average total target direct compensation for other NEOs and the portion that is performance based and/or at-risk.
For purposes of these charts, the percentage of total target direct compensation was determined based on the annual base salary and target incentive opportunities applicable to the active NEOs as of December 31, 2022.
The following table shows 2022 total target direct compensation and each component of total target direct compensation for the listed NEO as of December 31, 2022.

COMPENSATION DISCUSSION AND ANALYSIS (CD&A)
Executive Compensation Elements
Base Salary
Base salary provides our NEOs with a level of fixed pay commensurate with the employee’s role and responsibility. For 2022, the Compensation and Human Capital Committee increased the base salary by approximately 2% for Mr. Brown and 14% for Mr. Anderson. In making these decisions and recommendations, the Compensation and Human Capital Committee considered each of the Pay Factors discussed above. These salary adjustments became effective on March 1, 2022. The Compensation and Human Capital Committee also reviewed benchmark data, industry experience and performance when determining the compensation for Ms. Birmingham and Mr. Jefferson and for evaluating and recommending compensation for Mr. Yates to the Board of Directors for approval.
2022 Short-Term Incentive (STI) Program
2022 STI Objectives. The objectives of our 2022 STI program were to:

■ | Motivate our NEOs (and all other participants) to achieve critical financial and safety performance goals, which were directly aligned with the Company’s annual financial plan and key business imperatives; and

■ | Provide a competitive level of STI payout opportunities

The 2022 STI provides participants, including the NEOs, with the opportunity to earn a cash incentive award tied to achievement of financial performance goals (NOEPS weighted 70%) and safety goals (weighted 30%) over a one-year performance period. Every eligible employee has an incentive opportunity at threshold, target and stretch levels of performance. The Compensation and Human Capital Committee retains discretion to adjust STI awards, either on a formulaic or discretionary basis.
2022 STI Performance Measures. In January 2022, the Compensation and Human Capital Committee approved the following weighting of performance measures and goals to be used to determine the 2022 STI payouts for the NEOs and other participating employees.

​ | Measure | ​ | ​ | Weighting | ​ | ​ | Goal | ​
​ | Net Operating Earnings per Share | ​ | ​ | 70% | ​ | ​ | $1.44-1.46 | ​
​ | Safety Scorecard | ​ | ​ | 30% | ​ | ​ | 100% scorecard achievement | ​

Financial Measure (70%): The NOEPS financial performance goals were determined based on our 2022 annual financial plan. The Compensation and Human Capital Committee selected NOEPS as a financial measure because it is viewed by the Board as representative of our fundamental earnings strength, aligned with stockholder value creation, used internally for budgeting and reporting to the Board, and generally consistent with our external reporting of results.
The definition of NOEPS is income from continuing operations determined in accordance with GAAP, including, without limitation, the impact of incentive payouts and adjusted for certain items, such as fluctuations in weather and other significant unusual events disclosed in our earnings reports (examples of which may include transaction-related costs, debt extinguishment costs or certain income tax items).
Safety Measures (30%): The safety performance goals were determined based on our 2022 annual safety plan, which was approved by the Safety, Operations, Regulatory and Policy Committee (formerly known as the Environmental Safety and Sustainability Committee) of the Board of Directors. The Compensation and Human Capital Committee selected safety as a performance measure to focus STI participants, including the NEOs, on the criticality of establishing and maintaining practices and procedures to ensure the highest safety levels throughout Company operations.

2022 STI Performance Goals, Achieved Results and Percentage of Target Earned. The table below shows each performance measure and weight, target performance goal, achieved results and percentage of target earned based on achieved performance against performance goals. The 2022 STI program design included financial and safety performance measures that each had a target goal. For the officer level STI program participants, actual award values were 100% discretionary based upon individual performance. The 2022 overall achieved results for the performance measures was 115% of target. The program included a significant focus on safety measures, all of which were met at target. For non-officers, the STI program resulted in a payout opportunity of 91%. The program design included a significant focus on customer measures, all of which were not met. Management recommended, and the Compensation and Human Capital Committee approved, a weighted average approach to the final results. Therefore, all employee groups had a 94.44% payout opportunity pool funded for STI, subject to individual performance.

2022 Performance Share Units
PSU Objectives. The objectives of our 2022 PSU grants are to:

■ | Motivate NEOs to achieve critical long-term financial and total shareholder return goals (relative to peers) and achieve critical business imperatives related to safety, environmental and DE&I performance goals

■ | Align the interests of NEOs with stockholders

■ | Retain NEOs; and

■ | Provide competitive LTI opportunities (when aggregated with RSU grants, which are discussed below)

PSU Overview. In January 2022, the Compensation and Human Capital Committee approved the grant of PSUs to Messrs. Brown, Anderson and Vegas and the independent members of the Board (excluding Mr. Yates) approved a grant to Mr. Yates of PSUs. In May 2022, the Compensation and Human Capital Committee approved the grant of PSUs to Ms. Birmingham and Mr. Jefferson. The PSUs provide our NEOs the opportunity to earn shares of our common stock based on achieved results against three-year cumulative NOEPS (weighted 50%) and RTSR (weighted 50%) performance goals over a three-year performance period, subject to potential adjustment based on achieved results relating to safety, environmental and DE&I goals.
In addition, vesting of the PSUs is tied to the executive’s continued employment through the end of the vesting period (February 28, 2025), subject to special vesting rules in the event of death, retirement, disability, or a qualifying termination following a change-in-control of the Company prior to the vesting date. Termination for any other reason prior to February 28, 2025 will result in forfeiture of the 2022 PSUs. The number of PSUs earned and vested at the end of the three-year performance period will be settled in a like number of shares of our common stock.
2022 PSU Performance Measures. In January 2022, the Compensation and Human Capital Committee approved the following performance measures and goals reflected in the chart below to be used to determine each NEO’s payouts under their respective 2022 PSU grants.

COMPENSATION DISCUSSION AND ANALYSIS (CD&A)
Three-Year Cumulative NOEPS. The three-year cumulative NOEPS financial performance goals were determined based on our three-year financial plan. For the definition and calculation of NOEPS, see above under “2022 STI Performance Measures.”
The Compensation and Human Capital Committee selected this measure because it aligns the interests of our NEOs with those of our stockholders, and it supports the creation of sustainable stockholder value by growing earnings and providing a strong dividend.
The Compensation and Human Capital Committee selected an NOEPS performance measure for both the 2022 PSU grants and the 2022 STI because the Compensation and Human Capital Committee considers NOEPS to be a core driver of both our short-term and long-term financial performance and stockholder value creation for both the short-term and long-term.
The target three-year cumulative NOEPS performance goal is designed to be achievable with strong management performance over the three-year performance period.
Three-Year Relative Total Shareholder Return (RTSR). Three-year RTSR will be determined by the annualized growth in the price of a share of our common stock, assuming dividends are reinvested, over the period beginning January 1, 2022 and ending on December 31, 2024, compared to a similar calculation for a group of 32 energy services companies that are within our industry or providing similar services to ours or with which we compete for the sale of equity capital, 21 of which are in the Comparator Group.
The Compensation and Human Capital Committee selected this measure because it aligns the interests of our NEOs with those of our stockholders, and it supports the creation of sustainable stockholder value.
Modifiers. The number of PSUs earned based on achievement of three-year cumulative NOEPS and RTSR performance goals is subject to adjustment based on achievement against safety, environmental and DE&I performance goals. The Compensation and Human Capital Committee selected these performance measures to reflect the Company’s broad commitment to these priorities.
2022 Restricted Stock Units
In January 2022, the Compensation and Human Capital Committee approved the grant of RSUs to Messrs. Brown, Anderson and Vegas and the independent members of the Board (excluding Mr. Yates) approved a grant of RSUs to Mr. Yates. In May 2022, the Compensation and Human Capital Committee approved the grant of RSUs to Ms. Birmingham and Mr. Jefferson. These RSUs will vest based on the executive’s continued employment through February 28, 2025, subject to special vesting rules in the event of death, retirement, disability or a qualifying termination following a change-in-control of the Company prior to the vesting date. Termination for any other reason prior to February 28, 2025, will result in forfeiture of the 2022 RSUs. The number of RSUs that vest at the end of the three-year service period will be settled in a like number of shares of our common stock.
The Compensation and Human Capital Committee chose to grant RSUs to the NEOs because RSUs reward long-term service, help to retain NEOs over a multi-year service period, and align the interests of our NEOs with those of our stockholders.
Special Awards
2022 Special RSU Award. Mr. Anderson received a special RSU award of $500,000 to ensure his long-term leadership of the Company. This award is scheduled to vest based on his continued employment through January 28, 2025. Ms. Birmingham received a special RSU award of $1,161,855 to attract her to NiSource and to ensure her long-term leadership of the Company. Forty percent of this award is scheduled to vest based on her continued employment through July 1, 2023 and sixty percent on July 1, 2024. Mr. Jefferson received a special RSU award of $800,000 to attract him to NiSource and to ensure his long-term leadership of the Company. Fifty percent of this award is scheduled to vest based on his continued employment through each of July 1, 2023 and July 1, 2024, respectively. Special vesting rules apply in the event of retirement, death, disability, or a qualifying termination following a change-in-control of the Company.

2020 PSU Awards
In 2020, the Compensation and Human Capital Committee (and, in the case of the CEO, the independent members of the Board) approved LTI awards to Messrs. Hamrock, Brown, Anderson and Vegas in the form of PSUs (80% of the target 2020 LTI award). All the 2020 PSUs were subject to a threshold cumulative NOEPS performance trigger. Under the 2020 PSU design, 80% of the target PSUs were eligible to vest based on NOEPS performance above the trigger, with a +/- 25% RTSR performance modifier if top or bottom quartile RTSR performance was achieved. The remaining 20% of the target PSUs were eligible to vest based on the achievement of customer value framework goals.
The performance measures, goals and results for the 2020 PSUs as certified by the Compensation and Human Capital Committee, are shown below.

​ | Threshold Goal(1) | ​ | ​ | Trigger, Target and Stretch Three-Year Cumulative NOEPS Goals | ​ | ​ | 2020 PSU Results | ​ | ​ | % of Target PSU Earned Following Application of RTSR Modifier(2) | ​
​ | Three-Year Cumulative NOEPS | ​ | ​ | Trigger (50% Payout): $4.03 | ​ | ​ | Three-year Cumulative NOEPS $4.21(1) | ​ | ​ | 74% | ​
​ | Target (100% Payout): $4.25 | ​
​ | Stretch (200% Payout): $4.47 | ​
​ | Threshold Goal(1) | ​ | ​ | Three-Year Customer Value Framework Categories(3) | ​ | ​ |  | ​ | ​ | % of Target PSU Earned | ​
​ | Three-Year Cumulative NOEPS | ​ | ​ | Safety, Customer Care, Organizational Culture, and Environmental Impact | ​ | ​ | 1 of 4 Goals Achieved(3) | ​ | ​ | 5% | ​

(1) | The 2020 PSUs were eligible for vesting only if the cumulative NOEPS performance trigger of $4.03 over a three-year performance period was met. For the three-year period ending December 31, 2022, our adjusted cumulative NOEPS was $4.21, which exceeded the cumulative NOEPS trigger of $4.03 for the 2020-2022 performance period. Once the NOEPS threshold was met, both the NOEPS PSUs (80% of the target PSUs) and customer value framework PSUs (20% of the target PSUs) were eligible to vest. Our cumulative NOEPS performance from January 1, 2020 through December 31, 2022 reflects the total of the amounts disclosed in our earnings reports for such years plus a COVID-19 pandemic adjustment of $0.05 approved by the Compensation and Human Capital Committee in 2020. The 2020 NOEPS target of $4.38 was adjusted after the sale of Columbia Gas of Massachusetts (“CMA”). As a result of the CMA adjustment, “cumulative NOEPS” means the Company’s cumulative NOEPS, as reported in the Company’s annual financial statements with additional adjustments made to the targets and results for: (x) transactions that the Company discloses on Form 8-K filed with the SEC, including merger, acquisition, divestiture, consolidation or corporate restructuring, any recapitalization, reorganization, spin-off, split-up, combination, liquidation, dissolution, sale of assets or similar corporate transactions that meet disclosure thresholds; and (y) pending transactions as a result of requirements to present operations as “held for sale” under Accounting Standard Codification 205.”

(2) | 74% of the target PSU was eligible to vest based on three-year cumulative NOEPS. Our RTSR performance was in the second quartile resulting in no modification in the number of PSUs earned.

(3) | 5% of the target PSU was eligible to vest based on achievement of customer value framework goals related to environmental, as measured by reduced greenhouse gas emissions over the performance period of 2020 to 2022. The safety, customer care, and organizational culture goals were not met.

Vesting of the 2020 PSUs remained subject to the executive’s continued employment through February 28, 2023. The following table shows the target number of shares subject to the 2020 PSUs as well as the number of shares of common stock that vested pursuant to the terms of the 2020 PSUs.

​ | NEO (1) | ​ | ​ | Target Number of 2020 PSUs Awarded | ​ | ​ | Number of 2020 PSUs Vested | ​
​ | Joseph Hamrock | ​ | ​ | 120,095 | ​ | ​ | 94,875 | ​
​ | Donald E. Brown | ​ | ​ | 31,615 | ​ | ​ | 24,976 | ​
​ | Shawn Anderson | ​ | ​ | 5,498 | ​ | ​ | 4,343 | ​

(1) | As a result of Mr. Hamrock’s retirement, vested shares were prorated. As a result of Mr. Vegas’ resignation, all shares (31,615) were forfeited.

2021 Special PSU Awards
2021 Special PSUs. In January 2021, the Compensation and Human Capital Committee (and, in the case of the CEO, the independent members of the Board), granted special performance-based equity awards in the form of PSUs (“2021 Special PSUs”) to Messrs. Hamrock, Brown, Anderson and Vegas. The 2021 Special PSUs were granted to incentivize the retention of the leadership team and provide enhanced motivation to strive for the achievement of the goals required under the Company’s NiSource Next transformation initiative. Because the performance required for payouts under these awards is exceptional, with threshold payouts for the 2021 Special PSUs equivalent to target RTSR performance under the 2021 PSU program, the awards are designed to reward the achievement of the goals related to the NiSource Next transformation initiative and align with stockholder interest.
Under the program design, accelerated payout of 67% of the target award value may occur after two years if our RTSR performance results are at or above the utility peer group median. Any earned award is further adjusted by a safety magnifier to assure alignment with our safety performance. The Compensation and Human Capital Committee (and, in the case of the CEO, the independent members of the Board) set the award size at levels designed to provide a meaningful incremental incentive in relation to each executive’s total target direct compensation.
The performance measures, goals and results for the 2021 Special PSUs as certified by the Compensation and Human Capital Committee are shown below.

​ | Performance Measure | ​ | ​ | Target Goal | ​ | ​ | Achieved Results | ​ | ​ | % of Target STI Earned | ​
​ | FINANCIAL PERFORMANCE (100% weighting) | ​
​ | Relative Totals Shareholder Return (over 2 and 3 year Performance Period(1)) | ​ | ​ | 55th Percentile | ​ | ​ | 82nd Percentile | ​ | ​ | 177% | ​
​ | SAFETY SCORECARD (+/-20% modifier) | ​
​ | Average Annual STI Safety Scorecard Results (as % of Target) Over Three-Year Performance Period(1) | ​ | ​ | 100% | ​ | ​ | 99% | ​ | ​ | -1% | ​
​ | FINAL ACHIEVED RESULTS | ​ | ​ |  | ​ | ​ |  | ​ | ​ | 175% | ​

(1) | RTSR will be calculated over the two-year and three-year periods using methodology as described above under 2022 PSU Performance Goals. Safety scorecard results will generally be calculated as discussed above in the section entitled “2022 Short-Term Incentive (STI) Program” and will be averaged over the two-year and three-year periods. If performance results fall between two performance levels (for example, between target and stretch goals), the result is determined by interpolation.

Vesting of the 2021 Special PSUs remained subject to the executive’s continued employment through February 28, 2023. Special vesting rules apply in the event of death, retirement, disability or a qualifying termination following a change-in-control of the Company. Termination for any other reason prior to February 28, 2023, will result in forfeiture of the entire award, or the remaining portion of the award if such termination occurs after such date but prior to February 28, 2024. The following table shows the target number of shares subject to the 2021 Special PSUs as well as the number of shares of common stock that vested pursuant to the terms of the 2021 Special PSUs.

​ | NEO(1) | ​ | ​ | Target Number of 2021 PSUs Awarded | ​ | ​ | Number of 2021 PSUs Vested | ​
​ | Joseph Hamrock | ​ | ​ | 135,476 | ​ | ​ | 63,522 | ​
​ | Donald E. Brown | ​ | ​ | 40,663 | ​ | ​ | 31,731 | ​
​ | Shawn Anderson | ​ | ​ | 11,182 | ​ | ​ | 8,726 | ​

(1) | As a result of Mr. Hamrock’s retirement, vested shares were prorated. As a result of Mr. Vegas’ resignation, all shares were forfeited.

Other Compensation and Benefits
Our NEOs also participate in an executive deferred compensation plan, change-in-control and termination agreements, and an executive severance policy. In addition, we provide our NEOs with a limited number of perquisites and other broad-based employee benefits that are generally extended to our entire employee population. We believe that these other forms of compensation and benefits are aligned with our compensation objectives and are generally comparable to those that are provided to similarly situated executives at other comparable companies.
Severance and Change-in-Control Benefits. Each NEO is covered under a separate change-in-control and termination agreement (“CIC Agreement”). The CIC Agreements are intended to ensure that the NEOs continue to apply thoroughly objective judgment to appropriately safeguard stockholder value and maximize investor return in relation to any potential change-in-control. The CIC Agreements provide cash severance benefits upon a double-trigger (meaning there must be both a qualifying change-in-control and termination of employment) and do not include any “gross-up” payments to cover an executive’s excise taxes incurred by an executive with respect to the receipt of payments in connection with a change-in-control. Each NEO is subject to our executive severance policy.
Our 2020 Omnibus Plan provides for double-trigger vesting for equity awards that are assumed or replaced by an acquiring company upon a change-in-control. In the event equity awards are not assumed or replaced in a change-in-control, then the outstanding equity awards will vest upon the occurrence of such change-in-control.
For further information regarding the benefits to be received upon termination of employment or change-in-control, see the section entitled “2022 Executive Compensation – Potential Payments upon Termination of Employment or a Change-in-Control of the Company.”
Perquisites. Perquisites are not a principal element of our executive compensation program. We provide a limited number of perquisites to each NEO. We do not reimburse NEOs for the payment of individual income taxes they might incur in connection with their receipt of these benefits. For information regarding 2022 perquisites, see the 2022 Summary Compensation Table and footnote (4) to that table.
Deferred Compensation Plan. Eligible executives, including the NEOs, may elect to defer between 5% and 80% of their base salary and/or STI payout under our Executive Deferred Compensation Plan (the “Deferred Compensation Plan”). The Deferred Compensation Plan provides an opportunity for eligible executives to defer their cash compensation without regard to the limits imposed by the Internal Revenue Service (“IRS”) for amounts that may be deferred under our 401(k) Plan. For information regarding the Deferred Compensation Plan, see the 2022 Non-Qualified Deferred Compensation table and accompanying narrative.
Savings Programs. The NEOs are eligible to participate in the same tax-qualified 401(k) Plan as most employees and in a non-qualified defined contribution plan (the “Savings Restoration Plan”) maintained for eligible executives. The 401(k) Plan includes a Company match that varies depending on the pension plan in which the employee participates and a Company profit sharing contribution for most employees of between 0.5% and 1.5% of the employee’s eligible earnings based on achievement of the overall corporate NOEPS measure. In addition, for salaried employees hired after January 1, 2010 and non-union non-exempt employees hired after January 1, 2013, the 401(k) Plan includes a 3% Company contribution to the employee accounts (4.5% beginning in 2023). The Savings Restoration Plan provides for Company contributions in excess of IRS limits under the 401(k) Plan for eligible employees, including the NEOs. For information regarding the Savings Restoration Plan, see the 2022 Non-Qualified Deferred Compensation table and accompanying narrative.
Health and Welfare Benefits. We also provide the NEOs other broad-based benefits such as medical, dental, life insurance and long-term disability coverage on the same terms and conditions to all employees.

Executive Compensation Process and Guidelines
Role of the Compensation and Human Capital Committee
The Compensation and Human Capital Committee is responsible for establishing, implementing, and monitoring our executive compensation program objectives and assuring alignment with our business objectives. In overseeing our executive compensation programs, the Compensation and Human Capital Committee identifies and approves performance measures and goals under our STI and LTI programs. Additionally, the Compensation and Human Capital Committee approves annual long-term equity incentive awards and periodic long-term equity incentive awards granted to newly hired and promoted executive officers. The Compensation and Human Capital Committee also oversees the administration of our equity plans.
The Compensation and Human Capital Committee evaluates and determines the compensation of our executive leadership team, which is composed of senior executives who directly report to our CEO. The Compensation and Human Capital Committee reviews the performance and compensation of our CEO and our executive leadership team each year with input from Meridian and apprises the Board accordingly. For our CEO, the Compensation and Human Capital Committee evaluates CEO performance and submits its recommendations to the independent members of the Board for review and approval. When considering changes in compensation for our executive leadership team, including the NEOs, the Compensation and Human Capital Committee considers input from the CEO and the Senior Vice President, Chief Human Resources Officer and Meridian. Our CEO is not involved in making recommendations with respect to his compensation.
The Compensation and Human Capital Committee also has continuous involvement with our human resources talent management initiatives regarding our CEO and our executive leadership team. The Compensation and Human Capital Committee also leads our development and succession efforts by providing strategic direction as we identify key executive skill and capability talent priorities. The Compensation and Human Capital Committee reviews the performance of our CEO and executive leadership team against leadership skills and capability requirements designed to identify, attract and develop highly-qualified executives that promote continuous learning; foster our culture of equality, inclusion and diversity; deliver safety, reliability and environmental performance improvements; and ultimately support our long-term strategy to build value for all our stakeholders, including our customers, employees, communities and stockholders.
Independent Compensation Consultant
For 2022, the Compensation and Human Capital Committee engaged the services of Meridian as its independent compensation consultant to advise it with respect to executive compensation design, comparative compensation practices and compensation matters relating to the Board. The Compensation and Human Capital Committee takes recommendations from Meridian into consideration along with its evaluation of the individual performance of each executive officer.
Each year, the Compensation and Human Capital Committee evaluates the independence and quality of the services provided by its independent compensation consultant. In reviewing Meridian’s engagement for 2022, the Compensation and Human Capital Committee considered the factors set forth in SEC Rule 10C-1(b)(4) and the applicable NYSE rules and determined that Meridian was independent and there were no conflicts of interest with respect to Meridian’s work for the Compensation and Human Capital Committee.

Stock Ownership and Retention Guidelines
Our executive leadership team, which includes the NEOs, and other senior leaders are subject to stock ownership and retention guidelines. We maintain these guidelines to ensure that our executive leadership and senior leaders maintain a significant investment in our stock, which in turn helps to align the interests of our executive leadership and senior leaders with those of our stockholders.
Our executive leadership team and senior leaders are generally expected to satisfy their applicable ownership guideline (as described below) within five years of becoming subject to the guidelines. Once applicable share ownership levels are satisfied, the senior executive must continue to own enough shares to remain in compliance. Until such time as the applicable stock ownership guideline is satisfied, the CEO and Executive Vice Presidents are required to hold at least 50% of the shares of common stock received upon the vesting of equity awards. As of the record date, the NEOs are on a path to achieving the applicable ownership guideline within the 5-year requirement. Shares counted toward ownership targets include common stock held and unvested RSUs.

​ | Executive Level | ​ | ​ | Stock Ownership Level | ​
​ | CEO | ​ | ​ | 6x base salary | ​
​ | Executive Vice President | ​ | ​ | 3x base salary | ​
​ | Senior Vice President | ​ | ​ | 2x base salary | ​

Risk Management Policies and Guidelines
Trading Windows/Trading Plans. We restrict the ability of directors, executive officers and employees who work in designated areas to freely trade in our common stock because of their periodic access to our material non-public information. Under our insider trading policy, such persons are prohibited from trading in our securities during quarterly blackout periods, and at such other times as the General Counsel may deem appropriate.
Anti-Hedging Policy/Pledging. Under our Securities Transaction Compliance Policy for Certain Employees and our Securities Transaction Compliance Policy for Directors and Executive Officers, all directors, executive officers, and employees who work in designated areas are prohibited from engaging in short sales of our equity securities or buying or selling puts or calls or other options on our securities. We do not have such a policy for employees who work in areas other than the designated areas.
Compensation Recovery for Misconduct. Included in our 2020 Omnibus Plan is a “clawback” provision that states the employee shall reimburse the Company amounts received under STI and LTI awards if we are required to prepare an accounting restatement as a result of the employee’s misconduct.

ASSESSMENT OF RISK
We perform an annual risk assessment of our compensation program. We concluded our programs are not reasonably likely to have a material adverse effect on the Company, based on the following:

■ | Executive/Board Oversight—Our executive leadership and board regularly monitor our programs and people to ensure decisions are made with integrity and in the best long-term interests of the Company;

■ | Strategic Consistency—Our compensation program is aligned with our goals without promoting excessive risk;

■ | Sound Performance Criteria—Performance measures for incentive awards are consistent with long-term shareholder value and operational excellence; measures and underlying goals are approved by the Compensation and Human Capital Committee of the Board;

■ | Long-term Focus—Executive compensation is weighted toward LTIs, aligning executives with long-term results and shareholders;

■ | Performance Focus—LTI awards for executives are predominately performance-based;

■ | Stock Ownership Guidelines—Executives are subject to stock ownership guidelines set by the Compensation and Human Capital Committee; this further reinforces the need for a long-term view in decision making;

■ | Operational Excellence—Incentive compensation is partially tied to safety and other operational metrics to encourage a strong culture of safety and motivate the prioritization of safe operations; and

■ | Clawback Policy—Policies are in place to recoup compensation in the event of certain acts of misconduct and to prohibit hedging of our stock by senior executive officers.

Amounts reported in this column for 2022 represent the aggregate grant date fair value, computed in accordance with FASB ASC Topic 718, with respect to the PSUs and RSUs granted in 2022. The grant date fair value of the RSUs is calculated based on the average market price of our common stock on the grant date, less the present value of any dividends not received during the vesting period. With respect to the PSUs subject to NOEPS goals, grant date fair value is based on the closing stock price of our common stock at grant date. With respect to the PSUs subject to the RTSR goals, grant date fair value is calculated based on a Monte Carlo valuation technique in accordance with FASB ASC Topic 718. All of the PSUs are subject to performance conditions; therefore, the value reported in this column for these awards is based upon the probable outcome of such conditions. For information on the valuation assumptions used in these computations, see Note 14 to our consolidated financial statements included in our 2022 Annual Report on Form 10-K.

2022 EXECUTIVE COMPENSATION

(3) | For 2022, the STI amount for each NEO is based upon pro-rated salary earned during 2022 plus corporate and individual performance. For more information regarding 2022 corporate performance and the 2022 STI payout opportunities for the NEOs, please see the “2022 Short-Term Incentive (STI) Program” section in the CD&A under “Executive Compensation Elements” above. The funding pool for the 2022 STI was 94.44% of target (the formulaic amount). An individual performance-based adjustment was applied to Mr. Anderson, Mr. Jefferson, and Ms. Birmingham as determined by the CEO and as approved by the Compensation and Human Capital Committee. This adjustment was multiplied by the named executive officer’s formulaic STI amount to arrive at the final STI payout for 2022. The adjustment was based on the following: Mr. Anderson-150%: As the Senior Vice President Strategy & Chief Risk Officer, Mr. Anderson’s exceptional individual performance was significantly weighted on setting the strategic direction for the enterprise and driving financial results. He successfully led the completion of a strategic review to fund key initiatives for the Company’s long-term growth strategy; Ms. Birmingham-125%: In the newly created role of Executive Vice President & Chief Innovation Officer, Ms. Birmingham’s individual performance was significantly weighted on her drive and discipline in developing an IT 5-year roadmap and transformation discipline to the enterprise along with delivering a pragmatic and efficient approach to the Customer Experience; Mr. Jefferson-125%: As the Executive Vice President Operations & Chief Safety Officer, Mr. Jefferson’s individual performance was weighted on setting the strategic direction to drive industry leading, risk informed, asset management capability across the utility companies and for his execution of the centralization of core utility and construction operations.

The following table shows the value of the 2022 PSUs reported in the 2022 Summary Compensation Table at the grant date assuming that the highest level of performance conditions will be achieved and less the present value of any dividends not received in the vesting period. For information on the valuation assumptions used in these computations, see Note 14 to our consolidated financial statements included in our 2022 Annual Report on Form 10-K.

(a) | All perquisites are valued based on the aggregate incremental cost to the Company, as required by the rules of the SEC. Please see the “Other Compensation and Benefits – Perquisites” section above in the CD&A under “Executive Compensation Elements” for additional information about the perquisites we provide to the NEOs. The perquisite amounts listed include financial planning and tax services for some of the NEOs (Messrs. Hamrock, Brown, and Anderson, and Ms. Birmingham). For Mr. Yates, the perquisite amount listed above reflects the value of his personal use of Company or leased aircraft. Regarding use of Company or leased aircraft, the costs shown reflect the incremental cost to the Company of Mr. Yates’ use of Company or leased aircraft attributable to commuting to or from his residence or other personal location in connection with Company business.

2022 EXECUTIVE COMPENSATION
of the personal use of Company aircraft is calculated based on the aggregate variable operating costs to the Company, including fuel costs, trip-related maintenance, universal weather-monitoring costs, on-board catering, landing/ramp fees, and other miscellaneous variable costs. Fixed costs which do not change based on usage, such as pilots’ salaries, the amortized costs of the aircraft, and the cost of maintenance not related to trips are excluded. With respect to flights on a leased or chartered airplane, direct operating costs equal the amount that the third party charges the Company for such trip. NEOs are permitted to invite their spouse or other guests to accompany them on business trips when space is available; however, in such events, the NEO is imputed income in accordance with IRS guidelines. Beginning in 2023, the Company adopted a policy that requires NEOs to reimburse the Company for the direct operating costs of any personal travel, except Mr. Yates is not required to reimburse the Company for the cost of travel to meetings of the board of directors of other companies on which board he serves or for the cost of having his spouse accompany him on business trips if spouses are invited by the event organizer to attend.

(b) | This column reflects Company matching contributions and profit-sharing contributions made on behalf of each of the NEOs and a Company non-elective contribution of 3% of compensation to the 401(k) Plan. The 401(k) Plan is a tax-qualified defined contribution plan, as described above in the “Other Compensation and Benefits – Savings Programs” section in the CD&A under “Executive Compensation Elements”.

(c) | This column reflects Company matching contributions and profit-sharing contributions made on behalf of all eligible NEOs and a Company non-elective contribution of 3% of compensation in excess of IRS limits to the Savings Restoration Plan. The Savings Restoration Plan is a non-qualified defined contribution plan, as described above in the “Other Compensation and Benefits – Savings Programs” section in the CD&A under “Executive Compensation Elements” above, and in the narrative following the 2022 Non-Qualified Deferred Compensation Table.

(2) | The information in the “Threshold,” “Target,” and “Maximum” columns reflects the potential share payouts under the portion of the 2022 LTI award granted in the form of PSUs (for the annual program, PSUs represented 80% of the LTI award for Messrs. Brown, Jefferson and Vegas, and Ms. Birmingham and 70% of the award for Mr. Anderson. Under the terms of the PSU awards, the PSUs will be earned based on achievement of goals relating to NOEPS and relative total shareholder return, subject to a +/-20% safety modifier, +/-10% environmental modifier, and +/-10% workforce diversity modifier. The amount reported in the “Threshold” column represents the minimum level of the PSUs that may vest based on the achievement of the threshold NOEPS goal and threshold RTSR goal, -20% safety modifier, -10% environmental modifier, and -10% workforce diversity modifier for the 3-year program. The amount reported in the “Target” column represents target achievement of the NOEPS and RTSR goals. The amount reported in the “Maximum” column represents maximum achievement of the maximum NOEPS goal and threshold RTSR goal, +20% safety modifier, +10% environmental modifier, and +10% workforce diversity modifier for the 3-year program.

(6) | For a description of the Savings Restoration Plan, please see the “Other Compensation and Benefits – Savings Programs” section in the CD&A under “Executive Compensation Elements” and the narrative accompanying this table. These contributions are fully vested.

We sponsor the Savings Restoration Plan and the Deferred Compensation Plan, two non-qualified defined contribution plans, neither of which credits above-market or preferential earnings. Amounts due under the plans are unsecured contractual obligations that are paid from our general assets.
Savings Restoration Plan. The Savings Restoration Plan provides a supplemental benefit to eligible employees, including the NEOs, equal to the difference between: (i) the employer contributions (including matching and profit sharing contributions) an employee would have received under our Retirement Savings Plan had such benefit not been limited by Sections 415 (a limitation on annual contributions under a defined contribution plan of $61,000 for 2022) and 401(a)(17) (a limitation on annual compensation of $305,000 for 2022) of the Code, and the Retirement Savings Plan’s definition of compensation, which excludes deferrals into our Deferred Compensation Plan for purposes of calculating certain employer contributions, minus (ii) the actual employer contributions the employee received under the Retirement Savings Plan. Amounts credited under the Savings Restoration Plan are deferred on a pre-tax basis. Participants’ accounts under the Savings Restoration Plan are 100% vested. Employees designate how these contributions will be invested, with the investment options generally the same as those available under our Retirement Savings Plan.
The timing of payment under the Savings Restoration Plan differs depending on whether the amounts were earned and vested before January 1, 2005 (“Pre-409A Amounts”) or after December 31, 2004 (“Post-409A Amounts”). Pre-409A Amounts generally are payable at the time when amounts under the Retirement Savings Plan are paid. Participants may elect in any year to withdraw Pre-409A Amounts, but that withdrawal is subject to a 10% reduction to the extent the payment is before the amount was otherwise payable under the Retirement Savings Plan. Post-409A Amounts generally are paid within 45 days after separation from service, although specified employees (within the meaning of Section 409A of the Code) are subject to a six-month payment delay in accordance with Section 409A of the Code. Participants may not elect to receive early in-service distributions of Post-409A Amounts. Both Pre-409A Amounts and Post-409A Amounts may be distributed upon an unforeseeable emergency, as determined in accordance with the terms of the Savings Restoration Plan. The form of payment for the Pre-409A Amounts is the same form that the participant elected under the Retirement Savings Plan. The form of payment for Post-409A Amounts depends on when the participant made the payment election, as reflected below:

(1) | If the election was made before January 1, 2014, the payment options were the following: lump sum, monthly installments, semi-annual installments, and annual installments. Such installments are substantially equal and made over the period of time elected, not greater than 15 years.

(2) | If elected on or after January 1, 2014, and before November 1, 2020, the payment options were the following: lump sum or annual installments. Installment payments are substantially equal and made over the period of time elected, not greater than 15 years.

(3) | If elected on and after November 1, 2020, the only payment option is one lump sum.

(4) | If a participant has not made a timely and valid election as to the form of payment, payment is made in one lump sum.

Deferred Compensation Plan. The Deferred Compensation Plan provides employees at certain job levels including the NEOs, the ability to defer compensation on a pre-tax basis, including compensation that would otherwise be limited by the Code. Participants may elect to defer and invest between 5% and 80% of their base compensation and between 5% and 80% of their annual bonus on a pre-tax basis. Employees designate how their contributions will be invested, with the investment options generally the same as those available under our Retirement Savings Plan. Employee contributions and any earnings thereon are 100% vested. The timing of payment under the Deferred Compensation Plan generally is the March 31st after the date of the participant’s separation from service. This timing applies both to the Pre-409A Amounts and Post-409A Amounts. In the case of Post-409A Amounts payable to specified employees within the meaning of Section 409A of the Code, payments generally will not be payable until six months after the date of separation from

service. Participants also may elect to receive in-service distributions of both Pre-409A Amounts and Post-409A Amounts. If a participant requests an in-service distribution of a Pre-409A Amount with less than 12 months’ advance notice, however, the distribution is subject to a 10% reduction. Participants may delay the commencement of distributions for five years after their originally scheduled payment date, in accordance with the subsequent deferral procedures under Section 409A of the Code. Both Pre-409A Amounts and Post-409A Amounts also may be paid upon an unforeseeable emergency, as determined in accordance with the terms of the plan. The form of payment for both amounts may be either a lump sum or annual installments of up to 15 years, as elected by the participant.
Potential Payments upon Termination of Employment or a Change-in-Control of the Company
All of the NEOs are eligible for certain benefits, upon certain types of terminations of employment, including a termination of employment involving a change-in-control of the Company (“Change-in Control”). Any benefits received under these agreements for Messrs. Hamrock and Vegas are reflected in the Summary Compensation Table. These benefits are in addition to the benefits to which they would be entitled upon a termination of employment generally (i.e., (i) vested retirement benefits accrued as of the date of termination, (ii) stock-based awards that are vested as of the date of termination, and (iii) the right to continue medical coverage pursuant to COBRA). The additional benefits are described below.
Executive Severance Policy. Our Executive Severance Policy provides severance pay and other benefits to terminated employees at a certain job level, including our NEOs, provided they satisfy the terms of the policy. No severance pay or other benefits are paid under this policy if the termination of employment occurs in connection with a Change-in-Control. Under the Executive Severance Policy, an employee becomes eligible to receive benefits only if he or she is terminated under any of the following scenarios: (a) a position elimination due to a reduction in force or other restructuring; (b) a position relocation of more than 50 miles from its current location that results in a longer commute of more than 20 miles and the employee chooses not to relocate; or (c) constructive termination. Constructive termination means a material reduction with respect to: (1) the scope of the employee’s position; (2) the employee’s base pay; or (3) the employee’s annual incentive opportunity; and as a result of any such event, the employee chooses to terminate employment. Under our Executive Severance Policy, an eligible employee receives severance pay in the amount of 52 weeks of base salary at the rate in effect on the date of termination. The employee also receives a lump sum amount equivalent to 130% of 52 weeks of COBRA (as defined in the Code and the Employee Retirement Income Security Act of 1974) continuation coverage premiums and outplacement services.
Change-in-Control and Termination Agreements. As of December 31, 2022, we had CIC and Termination Agreements with each of the NEOs. We entered into these agreements based upon our belief that they are in the best interests of the stockholders. They are designed to help ensure that in the event of extraordinary events, a thoroughly objective judgment is made on any potential corporate transaction, so that stockholder value is appropriately safeguarded and maximized. The CIC and Termination Agreements provide for cash severance benefits if the executive terminates employment for “Good Reason” (as defined below) or is terminated by us for any reason other than “Good Cause” (as defined below) within 24 months following certain Change-in-Control events (referred to as a “double trigger”). In addition, pursuant to the terms of the 2020 Omnibus Plan and 2010 Omnibus Plan, the executives’ equity awards are subject to double trigger accelerated vesting in the event of a Change-in-Control unless an acquiring company does not assume or replace such awards upon the Change-in-Control. None of the agreements contain a “gross-up” provision to reimburse executives for excise taxes incurred with respect to benefits received under a CIC and Termination Agreement. The CIC and Termination Agreements can be terminated on twelve months’ notice to the participant. For purposes of the CIC and Termination Agreements:
“Good Cause” shall be deemed to exist if, and only if, we notify the executive, in writing, within 60 days of our knowledge that one of the following events occurred: (1) the executive has engaged in acts or omissions constituting dishonesty, intentional breach of fiduciary obligation or intentional wrongdoing or malfeasance, in each case that results in substantial harm to the Company; or (2) the executive has been convicted of a criminal violation involving fraud or dishonesty.
“Good Reason” shall be deemed to exist if, and only if: (1) there is a significant diminution in the nature or the scope of the executive’s authorities or duties; (2) there is a significant reduction in the executive’s monthly rate of base salary and

the executive’s opportunity to earn a bonus under an incentive bonus compensation plan we maintain or the executive’s benefits; (3) we change by 50 miles or more the principal location at which the executive is required to perform services as of the date of a Change-in-Control; or (4) there is a material breach of the CIC and Termination Agreement. The CIC and Termination Agreements provide for a lump sum payment of two (three in the case of Mr. Yates) times the executive’s current annual base salary and target annual incentive bonus compensation. The executive will also receive a pro rata portion of the executive’s targeted annual incentive bonus for the year of termination. The CIC and Termination Agreements also provide that in the event of a Change-in-Control, the executive’s total Change-in-Control related payments will be equal to the best “net benefit” which is equal to the greater of: (i) the after-tax value of the executive’s total Change-in-Control related payments reduced by the 20% excise tax and other federal, state, local and other taxes; and (ii) the after-tax value of the executive’s Change-in-Control related payments that has been reduced to the extent necessary so that it would not trigger an excise tax, reduced for federal, state, local and other taxes (in each case, without a gross-up).
In addition, the CIC and Termination Agreements provide for the executives to receive a lump sum amount equivalent to 130% of the COBRA continuation premiums due for the two-year period (three in the case of Mr. Yates) following termination. In the event of a Change-in-Control, all outstanding equity awards granted to each of the NEOs under the applicable Omnibus Plan as of December 31, 2022, will vest only upon a termination of employment in connection with a Change-in-Control.
For the NEOs, we have quantified the potential payments upon termination under various termination scenarios as of December 31, 2022.

(2) | Special vesting rules apply in the event of retirement, disability or death pursuant to the terms and conditions of our equity award agreements. The number of shares that would have vested in the event of the executive’s disability or death is as follows: Mr. Yates, 48,550 shares; Mr. Brown, 134,219 shares; Mr. Anderson, 44,425 Shares; Ms. Birmingham, 15,050 shares; and Mr. Jefferson, 9,437 shares. The value of the equity grants was determined by multiplying the closing price of our common stock on December 30, 2022, which was $27.42 per share, by the number of shares that would have vested upon the retirement, disability or death, as applicable, of the NEO. For Mr. Brown, special vesting rules also apply in the event of disability or death under his cash-based Special Retention Award agreements. The amounts shown represent the pro-rata portion of his cash-based awards based on service months from the respective grant dates to December 31, 2022.

(3) | Amounts shown reflect payments to be made upon the involuntary termination of each NEO eligible under our Executive Severance Policy described above.

(4) | Amounts shown reflect payments to be made upon termination of employment in the event of a Change-in-Control of the Company under the CIC and Termination Agreements described. As described above, the CIC and Termination Agreements do not provide for any “gross-up” payments to executives for excise taxes incurred with respect to benefits received under a CIC and Termination Agreement. The CIC and Termination Agreements provide that in the event of a Change-in-Control, the executive’s total Change-in-Control will be equal to the best “net benefit” which is equal to the greater of: (i) the after-tax value of the executive’s total Change-in-Control related payments (reduced by the 20% excise tax and other federal, state, local and other taxes); and (ii) the after-tax value of the executive’s Change-in-Control related payments that has been reduced to the extent necessary so that it would not trigger an excise tax, reduced for federal, state, local and other taxes (in each case, without a gross-up). The amounts reflected in this table do not reflect the application of the best “net benefit” provision.

2022 EXECUTIVE COMPENSATION
Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are providing the following disclosure about the relationship of the annual total compensation of our employees to the annual total compensation of our CEO.
For 2022, our last completed fiscal year:

■ | The median annual total compensation of all employees (other than our CEO) was $148,962; and

■ | The annualized total compensation of our CEO, Lloyd Yates, was $7,234.339.

Based on this information, for 2022, the ratio of the annualized total compensation of Mr. Yates, our CEO during 2022, to the annual total compensation of the median employee is estimated to be 49 to 1.
To identify the median of the annual total compensation of all our employees (other than our CEO), as well as to determine the annual total compensation of our median employee and our CEO, we took the following steps consistent with Item 402(u) of Regulation S-K:

1. | We determined that, as of December 31, 2022, our employee population consisted of approximately 7,328 employees, with all of our employees located in the United States. This population consisted of our full-time, part-time and temporary employees, as determined for employment law purposes.

2. | To identify the “median employee” from our employee population, we prepared a full census of all our employees (except our CEO) using our existing centralized payroll database of base cash compensation (base salary plus overtime and shift premiums, calculated based on the hours worked during the relevant period) that is used internally to calculate annual cash incentive compensation and profit-sharing eligibility. We used base cash compensation as our compensation measure as it is the principal form of compensation delivered to all of our employees. We used the same median employee as 2021 where we used the following methodology:

■ | We adjusted as of December 31, 2021, the compensation of 638 full-time employees and 19 part-time employees hired during 2021 to annualize compensation for any portion of the measurement period that they were not with the Company.

■ | Although all of our employees are eligible for an annual cash incentive (paid in 2022 for 2021 individual and Company performance), we excluded this for all employees because we determined its inclusion would not have a meaningful effect on the determination of the median employee.

■ | Since we do not widely distribute annual equity awards to our employees, such awards were excluded from our compensation measure.

3. | We identified our median employee from a full census report compiled using base cash compensation as our consistently applied compensation measure. Since all our employees are located in the United States, as is our CEO, we did not make any cost-of-living adjustments identifying the “median employee.”

4. | Once we identified our median employee, we combined all of the elements of such employee’s compensation for 2022 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $148,962.

5. | For the year ended December 31, 2022, the total compensation for our CEO, Mr. Yates, was $7,113,506 as reported in the “Total” column of the Summary Compensation Table of this Proxy Statement. As permitted by SEC rules, the Company elected to annualize the compensation of Mr. Yates, who became CEO of the Company on February 14, 2022. To annualize Mr. Yates’ compensation for 2022, the annual base salary for the CEO was used to reflect a full year of earnings annualized at $1,000,000 where his partial year salary earnings were $879,167.

With respect to the PSUs subject to NOEPS goals, grant date fair value is based on the closing stock price of our common stock at grant date. With respect to the PSUs subject to the RTSR goals, grant date fair value is calculated based on a Monte Carlo valuation technique in accordance with FASB ASC Topic 718. All of the PSUs are subject to performance conditions; therefore, the value reported in this column for these awards is based upon the probable outcome of such conditions.

PROPOSAL 2 – ADVISORY APPROVAL OF NEO COMPENSATION
Pursuant to Section 14A of the Exchange Act, we are asking stockholders to approve, in a non-binding advisory vote, the compensation paid to our NEOs, as disclosed under the headings “2022 Executive Compensation” and “Compensation Discussion and Analysis (CD&A)” above, commonly known as a “Say-on-Pay” proposal.
At the 2017 annual meeting of stockholders, we provided our stockholders with an advisory vote regarding how frequently the Company will conduct future stockholder advisory votes to approve the compensation paid to our NEOs. More than a majority of the shares present or represented at the meeting were voted in favor of an annual vote, consistent with the Board’s recommendation. Based on these results, the Board has determined to hold an annual advisory vote on the compensation paid to our NEOs.
The Board encourages stockholders to carefully review the 2022 Executive Compensation and Compensation Discussion and Analysis (CD&A) sections of this Proxy Statement, for a thorough discussion of our executive compensation program and philosophy. Our compensation program is designed to be significantly performance-based and to attract and retain highly qualified individuals who enhance long-term stockholder value by contributing to our ongoing success. All facets of our compensation program are regularly monitored by the Compensation and Human Capital Committee to ensure that the program is well-tailored to fulfill our compensation philosophy and objectives.
In considering this proposal, stockholders may wish to consider the following factors that we believe demonstrate our commitment to maintaining a robust compensation program:

■ | Compensation is closely tied to both corporate and individual performance;

■ | Annual and long-term incentive compensation opportunities are contingent on the Company achieving pre-established goals;

■ | Total compensation packages are competitive with those offered by members of our Comparator Group;

■ | Perquisites are appropriately limited in number and modest in dollar value; and

■ | We believe our compensation program does not create incentives for behaviors that create material risk to the Company.

As discussed in the Compensation Discussion and Analysis (CD&A) and 2022 Executive Compensation sections of this Proxy Statement, the Compensation and Human Capital Committee and the Board believe that our executive compensation program fulfills the objectives of our compensation philosophy in a prudent and effective manner.
Accordingly, the following resolution is submitted for an advisory stockholder vote at the Annual Meeting:
RESOLVED, that the compensation paid to our NEOs, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby approved on an advisory basis.
As this is an advisory vote, the result will not be binding on the Company, the Board or the Compensation and Human Capital Committee, although the Compensation and Human Capital Committee and the Board will carefully consider the outcome of the vote when evaluating our compensation program and philosophy.
Vote Required
The affirmative vote of a majority of the shares present at the virtual Annual Meeting or represented by proxy at the meeting and entitled to vote is needed to approve the advisory vote on the compensation of the NEOs. Proxies submitted without direction pursuant to this solicitation will be voted “FOR” the advisory approval of executive compensation of our NEOs. Abstentions by those present or represented by proxy will have the same effect as a vote against the Say-on-Pay proposal. Brokers will not have discretionary authority to vote on the Say-on-Pay proposal. Accordingly, there could be broker non-votes, which will have no effect on the vote.
THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL OF NEO COMPENSATION ON AN ADVISORY BASIS.

PROPOSAL 3 – ADVISORY APPROVAL OF THE FREQUENCY OF FUTURE ADVISORY VOTES ON NEO COMPENSATION
In addition to the Say-on-Pay proposal above, we are asking stockholders to approve, on an advisory basis, the frequency with which the Company should ask stockholders for advisory approval of executive compensation, commonly known as a “Say-on-Frequency” proposal. You may cast a vote as to whether a Say-on-Pay vote should be held every one, two or three years, or you may abstain. Pursuant to Section 14A of the Exchange Act, this non-binding vote is held at least every six years. Because our last Say-on-Frequency vote was held at the 2017 annual meeting, we are again holding a Say-on-Frequency vote at the Annual Meeting. At our 2017 annual meeting, a majority of stockholders voting on the matter indicated a preference for holding the Say-on-Pay vote on an annual basis. Accordingly, the Board resolved that the non-binding advisory vote to approve the compensation of our NEOs would be held on an annual basis at least until the next Say-on-Frequency vote.
The Board values stockholders’ opinions and believes it would benefit from direct, timely feedback on the Company’s executive compensation program. Accordingly, after careful consideration, the Board unanimously recommends that stockholders vote for the option of “one year” to provide stockholder advisory approval of executive compensation on an annual basis.
The following resolution is submitted to stockholders for an advisory vote at the Annual Meeting:
RESOLVED, that the stockholders advise the Company to hold a stockholder vote for the advisory approval of the compensation paid to the Company’s NEOs every:

■ | One year;

■ | Two years; or

■ | Three years.

As this is an advisory vote, the result will not be binding on the Company, the Board or the Compensation and Human Capital Committee, although the Compensation and Human Capital Committee and the Board will carefully consider the outcome of the vote when evaluating our compensation program and philosophy.
Vote Required
The Say-on-Frequency option that receives the greatest number of votes from the stockholders will be considered the Say-on-Frequency option approved by the stockholders. Proxies submitted without direction will be voted for the “ONE YEAR” frequency. Abstentions by those present or represented by proxy and broker non-votes will not be voted with respect to the “Say-on-Frequency” proposal and, therefore, will have no effect on the outcome. Brokers will not have discretionary authority to vote on the “Say-on-Frequency” proposal. Accordingly, there could be broker non-votes, which will have no effect on the vote.
THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR “ONE YEAR” AS THE FREQUENCY OF FUTURE ADVISORY VOTES ON NEO COMPENSATION.

PROPOSAL 4 – RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee of the Board is directly responsible for the appointment, compensation, retention and oversight of the independent registered public accounting firm retained to audit our financial statements. The Audit Committee appointed Deloitte as our independent registered public accounting firm for 2023. As part of its oversight of our relationship with our independent registered public accounting firm and to assure continuing independence of such firm, the Audit Committee considers whether it is appropriate to adopt a policy of rotating its independent registered public accounting firm on a regular basis. Further, in conjunction with ensuring the rotation of such firm’s lead engagement partner, the Audit Committee and its Chair are directly involved with the selection of Deloitte’s lead engagement partner. The Audit Committee also reviews proposals for all auditing services (including fees and terms thereof) of our independent registered public accounting firm and approves all such proposals prior to the commencement or performance of such services, subject to the pre-approval policies and procedures described under “Independent Registered Public Accounting Firm Fees.”
Deloitte has served as our independent registered public accounting firm since 2002 and has the requisite understanding of our business, accounting policies and practices, and internal control over financial reporting to drive audit quality and efficient fee structures. As a result of this expertise, and, as noted above, the Audit Committee’s oversight designed to assure continuing independence, the Board and its Audit Committee consider Deloitte well qualified to serve as our independent registered public accounting firm. Further, the Board believes that the continued retention of Deloitte is in our best interest and the best interest of our stockholders. Although action by stockholders for this matter is not required, the Board and the Audit Committee believe that it is appropriate to seek stockholder ratification of this appointment in order to provide stockholders a means of communicating the stockholders’ level of satisfaction with the performance of the independent registered public accounting firm and their level of independence from management. If the proposal is not approved and the appointment of Deloitte is not ratified by the stockholders, the Audit Committee will take this into consideration and will reconsider the appointment. A representative of Deloitte will be present at the virtual Annual Meeting, will be given an opportunity to make a statement if he or she so desires and will be available to respond to appropriate questions.
Vote Required
The affirmative vote of a majority of the shares present during the virtual Annual Meeting or represented by proxy and entitled to vote is needed to ratify the appointment of Deloitte as our independent registered public accounting firm for 2023. Proxies submitted without direction pursuant to this solicitation will be voted “FOR” the ratification of the appointment of Deloitte. Abstentions by those present or represented by proxy will have the same effect as a vote against the proposal. Brokers will have discretionary authority to vote on this proposal, and, accordingly, there will not be any broker non-votes.
THE BOARD AND ITS AUDIT COMMITTEE UNANIMOUSLY RECOMMEND A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF DELOITTE AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2023.

PROPOSAL 5 – AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK
The Board has adopted and approved, and is recommending to stockholders for approval, an amendment to our Certificate of Incorporation to increase the number of authorized shares of common stock from 600 million to 750 million and a corresponding increase to the number of authorized shares of all classes of capital stock from 620 million to 770 million. The proposed amendment would not increase the number of authorized shares of preferred stock.
Under our Certificate of Incorporation, the total number of shares of all classes of stock which the Company has the authority to issue is 620 million. Of these authorized shares, common stock comprises 600 million shares and preferred stock comprises 20 million shares. As of March 14, 2023, 416,935,061 shares of common stock were issued, including 3,963,255 treasury shares, with 97,962,697 shares of common stock reserved for possible future issuance under our stock plans, our at-the-market equity offering (“ATM”) program and our Series A equity units. Approximately 85,102,242 authorized shares of common stock remain available for issuance for future purposes and the Board deems it advisable to increase our authorized shares of common stock. The adoption of the proposed amendment would provide for an additional 150 million shares of common stock for future issuance. As of March 14, 2023, we also had 1,302,500 shares of preferred stock issued.
The following table sets forth the number of authorized, outstanding, and reserved shares of common stock, as of March 14, 2023:

​ | Total Authorized Shares of Common Stock | ​ | ​ | ​600,000,000 | ​
​ | Less: Issued and Outstanding Shares, including Treasury | ​ | ​ | ​416,935,061 | ​
​ | Shares of Common Stock Available for Future Issuance | ​ | ​ | ​183,064,939 | ​
​ | Shares of Common Stock Reserved for Future Issuance Under: | ​ | ​ |  | ​
​ | ​ATM Program | ​ | ​ | ​14,370,314 | ​
​ | ​Omnibus Incentive Plan | ​ | ​ | ​11,494,634 | ​
​ | Employee Stock Purchase and Retirement Savings Plan | ​ | ​ | ​1,718,007 | ​
​ | Series A Equity Units | ​ | ​ | 70,379,742 | ​
​ | Total Shares of Common Stock Reserved for Future Issuance | ​ | ​ | ​97,962,697 | ​
​ | Shares Available for Future Issuance, Less Reserved Shares | ​ | ​ | ​85,102,242 | ​

Our business is capital intensive, requiring significant resources to fund operating expenses, capital project expenditures, scheduled debt maturities and interest payments, and dividend payments on our common stock and preferred stock. In addition to internal sources to fund liquidity and capital requirements for 2023 and beyond, we expect to rely on external sources of funds, including, but not limited to, equity financings such as the previously announced ATM program we expect to put in place in 2025 to maintain credit metrics as our growth investments continue.
The Board believes that it is advisable and in the best interests of our stockholders to increase the number of authorized shares of common stock to provide us with greater flexibility in considering and planning for future business needs, such as raising additional capital through the sale of equity securities, convertible debt securities or other equity-linked securities, purchases under our employee stock plans, grants of equity incentive awards to employees (subject to any required future stockholder approvals under equity plans), potential strategic transactions, stock dividends, stock splits, and other general corporate purposes. Approval of this amendment by stockholders at the Annual Meeting will enable us to take timely advantage of market conditions and other opportunities that may become available to us without the expense and delay of arranging a special meeting of stockholders in the future. If the proposed amendment is adopted, we would be permitted to issue the authorized shares of common stock without further stockholder approval, except to the extent otherwise required by law, any rules or listing requirements of the NYSE, or by our Certificate of Incorporation.

TABLE OF CONTENTS

PROPOSAL 5 – AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK
Other than the planned annual equity financing described above and the routine practices of issuing shares pursuant to employee stock plans and employee equity incentive awards, we have no present plans, proposals, or arrangements with respect to the issuance of any additional shares of common stock authorized upon approval of the proposed amendment.
Existing holders of shares of our common stock have no preemptive rights under our Certificate of Incorporation to purchase any additional shares of common stock issued by the Company. The additional shares of common stock, if and when issued, would have the same rights and privileges as the shares of common stock currently authorized. Approval of this proposal and the issuance of additional authorized shares of common stock would not affect the rights of the holders of currently outstanding shares of our common stock, except for the effects incidental to increasing the number of shares outstanding. The effects include dilution of voting power of existing stockholders, decreasing earnings per share, and, depending on the price at which they are issued, could be dilutive to our existing stockholders.
We have not proposed the increase in the authorized number of shares of common stock with the intention of using the additional shares for anti-takeover purposes, although an issuance of additional shares could, in certain circumstances, make an attempt to acquire control of the Company more difficult. We are not at this time aware of any such attempts and we are not proposing this increase in response to any third-party effort to acquire control of the Company.
The Board has approved, and is now submitting for approval by our stockholders, an amendment to Article IV of the Certificate of Incorporation as set forth in Appendix B to the proxy statement to increase the number of authorized shares of common stock from 600 million to 750 million and a corresponding increase to the number of authorized shares of capital stock from 620 million to 770 million. The Board has determined that the amendment is advisable and in the best interest of our stockholders.
If our stockholders approve this proposal, we plan to file the proposed amendment promptly with the Secretary of State of the State of Delaware, and the proposed amendment will become effective immediately upon the filing.
Vote Required
The affirmative vote of a majority of the outstanding shares of our common stock is needed to approve the amendment to the Certificate of Incorporation. Proxies submitted without direction pursuant to this solicitation will be voted “FOR” approval of the amendment. Brokers will have discretionary authority to vote on this proposal, and, accordingly, there will not be any broker non-votes. Abstentions will have the same effect as a vote against the proposal.
THE BOARD RECOMMENDS A VOTE “FOR” APPROVAL OF THE AMENDMENT TO OUR CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK.

PROPOSAL 6 – STOCKHOLDER PROPOSAL REQUESTING THAT OUR BOARD ADOPT A POLICY REQUIRING SEPARATION OF THE ROLES OF CHAIRMAN OF THE BOARD AND CEO
Mr. John Chevedden of 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, who beneficially owns a requisite number of shares of common stock, has informed the Company that he plans to present the following proposal at the meeting.
Proposal 6 – Independent Board Chairman
Shareholders request that the Board of Directors adopt an enduring policy,and amend the governing documents as necessary in order that 2 separate people hold the office of the Chairman and the office of the CEO.
Whenever possible, the Chairman of the Board shall be an independent director.
The Board has the discretion to select a Temporary Chairman of the Board who is not an independent director to serve while the Board is seeking an Independent Chairman of the Board on an accelerated basis.
It is a best practice to adopt this policy soon. However, this policy could be phased in when there is a contract renewal for our current CEO or for the next CEO transition.
The roles of Chairman and CEO are fundamentally different and should be held by 2 directors, a CEO and a Chairman who is completely independent of the CEO and our company. The job of the CEO is to manage the company. The job of the Chairman is to oversee the CEO and management.
This proposal simply translates the current practice at NiSource of an independent chairman into an enduring policy. This proposal is more important to NiSource because NiSource has not named in one place the duties of a lead director should NiSource not have an independent board chairman.
Please vote yes: Independent Board Chairman - Proposal 6
Board of Directors’ Statement in Opposition
Your Board of Directors unanimously recommends a vote AGAINST this proposal.
The Board of Directors and its ESN&G Committee have considered this proposal and concluded that it is unnecessary and not in the best interests of our stockholders. The Board recommends a vote AGAINST this proposal for the following reasons:

■ | Providing our Board the flexibility to determine our leadership structure at a given time and based on relevant circumstances best serves the Company and our stockholders;

■ | For more than 16 years—since late 2006—the offices of Chairman and CEO have been held by different individuals, with the Chairman being an independent director; and

■ | Our existing governance practices and current leadership structure promote effective and independent Board oversight.

PROPOSAL 6 – STOCKHOLDER PROPOSAL REQUESTING THAT OUR BOARD ADOPT A POLICY REQUIRING SEPARATION OF THE ROLES OF CHAIRMAN OF THE BOARD AND CEO
Providing our Board the flexibility to determine our leadership structure at a given time and based on relevant circumstances best serves the Company and our stockholders.
Our Corporate Governance Guidelines do not provide for a fixed policy with respect to combining or separating the offices of Chairman and CEO. Rather than taking a “one-size-fits-all” approach to Board leadership, our existing policies provide the Board flexibility to configure the leadership of the Board and the Company in the way that best serves the Company’s interests at the time. The most effective leadership structure at a given time will depend on a variety of factors, including the leadership, skills, and experience of each of the CEO, the Chairman, and the other members of the Board, as well as the needs of the business and other factors. The Board has deep knowledge of the strategic goals of the Company, the opportunities and challenges it faces, and the various capabilities of our directors and management, and is therefore best positioned to determine the most effective leadership structure to protect and enhance long-term stockholder value.
The Board has a fiduciary duty to evaluate and determine the Board’s leadership structure based on what will best serve stockholders’ interests under the circumstances, not pursuant to an inflexible pre-established policy. No single, fixed leadership model is appropriate in all circumstances. If this proposal were to be approved and implemented, it would deprive the Board of important flexibility to utilize its business judgment to determine the most effective leadership structure to serve the interests of the Company and its stockholders.
For more than 16 years—since late 2006—the offices of Chairman and CEO have been held by different individuals, with the Chairman being an independent director.
The Board recognizes the importance of having in place a structure that allows it to function in an appropriately independent manner and believes that independent Board leadership is a critical component of its governance structure. Our Corporate Governance Guidelines require us to have an independent lead director if the positions of Chairman and CEO are held by the same person. The Board regularly reviews the Company’s leadership structure and currently believes that separating the roles of Chairman and CEO is the most effective leadership structure for the Company to protect and enhance long-term stockholder value.
These roles have been separate since late 2006—meaning that the Board has already adopted a practice that is essentially the same as that requested by this proposal (without unduly depriving the Board of its flexibility). Pursuant to our Corporate Governance Guidelines, however, if the Board determines at some point in the future that combining the Chairman and CEO roles is in the Company’s best interest, the Board will then select a lead independent director, taking into account the recommendation of the ESN&G Committee. In that event, the lead independent director will be the presiding director for purposes of the NYSE rules and would have many responsibilities similar to the current Chairman.
Our existing governance practices and current leadership structure promote effective and independent Board oversight.
The Board believes that independent oversight involves not only having an independent Board leader, but also demonstrating a commitment to strong corporate governance. Our strong corporate governance policies and practices, including the items outlined below, empower our independent directors to effectively oversee management. These extensive strong governance practices include:

■ | Annual election of directors;

■ | Majority voting for all directors with resignation policy;

■ | Stockholder right to call special meetings;

■ | No supermajority voting provisions;

■ | Proxy access bylaw (3% ownership / 3 years / up to 20 stockholders / 20% of Board);

■ | Independent chairman separate from CEO;

2023 Proxy Statement|77

TABLE OF CONTENTS

PROPOSAL 6 – STOCKHOLDER PROPOSAL REQUESTING THAT OUR BOARD ADOPT A POLICY REQUIRING SEPARATION OF THE ROLES OF CHAIRMAN OF THE BOARD AND CEO

■ | All directors independent except CEO;

■ | Board committees comprised of all independent directors;

■ | Regular executive sessions of independent directors;

■ | Annual Board and committee evaluation process and ongoing evaluations of individual directors;

■ | Strategic and risk oversight by Board and committees;

■ | Annual “Say-on-Pay” advisory votes;

■ | Active and experienced Board;

■ | Robust succession planning and recent Board refreshment, with an average tenure on the Board of 6 years of service; and

■ | Regular stockholder engagement.

See the section titled “Corporate Governance” for more details on the Company’s commitment to strong corporate governance.
Summary
The Board has a long-standing history of strong corporate governance practices. The Board’s current structure, which is memorialized in our Corporate Governance Guidelines, provides for effective and independent Board oversight. In contrast, the proponent’s proposal calls for an inflexible policy that would restrict the Board’s discretion in meeting its fiduciary duty to evaluate and determine the appropriate structure to serve stockholder interests under the circumstances. Adoption of this policy is both unnecessary, especially in light of the Company’s actual practice of separating these roles for more than 16 years, and would preclude the Board from exercising its independent judgment to determine the most effective leadership structure in the future. In light of the current and long-standing practice of separating these roles, the substantial independent oversight of management by the Board, and the Company’s strong corporate governance practices, the Board believes the inflexible standard that would be imposed under this proposal is neither necessary, nor in the best interests of the Company or its stockholders.
Vote Required
If this proposal is properly presented at the meeting, approval requires the affirmative vote of a majority of the shares present at the virtual Annual Meeting or represented by proxy, and entitled to vote. Proxies submitted without direction pursuant to this solicitation will be voted AGAINST the stockholder proposal. Abstentions will have the same effect as a vote against the proposal. We believe brokers will not have discretionary authority to vote on this proposal, so there could be broker non-votes.
THE BOARD BELIEVES THAT THIS PROPOSAL IS NOT IN THE BEST INTERESTS OF STOCKHOLDERS AND RECOMMENDS A VOTE “AGAINST” THIS PROPOSAL.

AUDIT COMMITTEE REPORT
Our Audit Committee consists of Messrs. Bunting and Butler and Mss. Barbour and Lee. Each member of the Audit Committee is independent as defined by the applicable NYSE and SEC rules and meets the additional independence standard set forth by the Board in the Corporate Governance Guidelines. Each member of the Audit Committee also is “financially literate” for purposes of applicable NYSE rules. The Board has determined that Mr. Bunting, the Chair of the Audit Committee, and Mss. Barbour and Lee are each an “audit committee financial expert” as defined by SEC rules.
The Audit Committee is responsible for, among other things, assisting the Board in monitoring the integrity of our financial statements; reviewing the qualifications and independence of our independent registered public accounting firm; overseeing the performance of our internal audit function and independent registered public accounting firm; and reviewing our risk assessment process. The Audit Committee has the sole authority to appoint, retain or replace the independent registered public accounting firm and is directly responsible for the compensation and oversight of the work of the independent registered public accounting firm for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for us. The independent registered public accounting firm reports directly to the Audit Committee.
In the performance of its responsibilities, the Audit Committee met regularly with the members of our internal audit function and Deloitte, our independent registered public accounting firm, with and without management present, to discuss the results of its examinations, evaluations of our internal controls, and the overall quality of our financial reporting. In addition, the Audit Committee Chair and members of the Audit Committee met with Deloitte on a recurring basis to discuss the audit process, accounting and internal control matters, among other things. The Audit Committee also met regularly with management to discuss accounting, auditing, internal control, financial reporting, earnings and risk management matters. During these meetings, the Audit Committee reviewed and discussed, among other items, the audited consolidated financial statements, the unaudited interim financial statements, significant accounting policies applied by us in our financial statements and non-GAAP financial measures, with management and Deloitte. The Audit Committee also discussed with, and received regular status reports from, our internal audit function and Deloitte on the overall scope and plans for their audits, including the scope and plans for evaluating the effectiveness of internal controls over financial reporting.
The Audit Committee has discussed with Deloitte the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) and the SEC. The Audit Committee also has received the written disclosures and the letter from Deloitte required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with audit committees concerning independence and has discussed with Deloitte its independence. The Audit Committee has considered whether Deloitte’s provision of non-audit services to us is compatible with maintaining Deloitte’s independence. In reliance on the review and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2022.
The Audit Committee has appointed Deloitte to serve as our independent registered public accounting firm for the year ending December 31, 2022. In determining whether to reappoint Deloitte, the Audit Committee took into consideration various factors, including the historical and recent performance of Deloitte on the audit; the professional qualifications of the firm and the lead audit partner; the quality of ongoing discussions with Deloitte; the results of an internal survey of Deloitte’s service and quality; the appropriateness of fees; and evidence supporting the firm’s independence, objectivity and professional skepticism. Although the Audit Committee has sole authority to appoint the independent registered public accounting firm, the Audit Committee has recommended that the Board seek stockholder ratification of the appointment at the Annual Meeting as a matter of good corporate governance.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES
The following table represents the aggregate fees for professional services billed by Deloitte for the fiscal years ended December 31, 2022 and 2021.

​ |  | ​ | ​ | 2022 | ​ | ​ | 2021 | ​
​ | Audit Fees(1) | ​ | ​ | $5,395,170 | ​ | ​ | $4,691,000 | ​

​ | All Other Fees(5) | ​ | ​ | 13,584 | ​ | ​ | 101,649 | ​

(1) | Audit Fees — Fees for professional services performed by Deloitte for the audit of our annual financial statements in our Annual Report on Form 10-K and review of financial statements included in our Quarterly Report on Form 10-Q filings and services that are normally provided in connection with statutory and regulatory filings or engagements.

(2) | Audit-Related Fees — Fees for the assurance and related services performed by Deloitte that are reasonably related to the performance of the audit or review of our financial statements. These fees included services provided by Deloitte in connection with the audit of our benefit plans.

(3) | Tax Compliance — Fees for professional services performed by Deloitte with respect to tax compliance.

(4) | Tax Advice and Tax Planning — Fees for professional services performed by Deloitte with respect to tax advice and tax planning.

(5) | All Other Fees — Fees for permissible work performed by Deloitte that does not fit within the above categories.

Pre-Approval Policies and Procedures. During 2022, the Audit Committee approved all audit, audit-related and non-audit services provided to us by Deloitte prior to management engaging the independent registered public accounting firm for those purposes. The Audit Committee’s current practice is to consider for pre-approval annually all audit, audit-related and non-audit services proposed to be provided by our independent registered public accounting firm for the year. Additional fees for other proposed audit-related or non-audit services (not within the scope of the approved audit engagement) which have been properly presented to the Pre-Approval Subcommittee of the Audit Committee (consisting of Theodore H. Bunting, Jr.) by our Vice President and Chief Accounting Officer may be considered and, if appropriate, approved by the Pre-Approval Subcommittee of the Audit Committee, subject to later ratification by the full Audit Committee. In no event, however, will any non-audit service be approved by the Pre-Approval Subcommittee that would result in the independent registered public accounting firm no longer being considered independent under the applicable SEC rules. In appointing Deloitte as our independent registered public accounting firm, the Audit Committee has considered whether the provision of the non-audit services rendered by Deloitte is compatible with maintaining the firm’s independence.
DELINQUENT SECTION 16(A) REPORTS
Based on a review of reports filed with the SEC and written representations that no other reports were required under Section 16(a) of the Exchange Act, we believe that all of our directors, officers and beneficial owners of more than 10% of our common stock who are required to file such reports did file all such reports on a timely basis during 2022, except that Gunnar Gode’s disposition of 1,224 shares to satisfy his tax withholding obligations in connection with the vesting of an award of restricted stock units on August 10, 2022 was reported after the filing deadline on a Form 5 filed on January 4, 2023. This delinquent filing was due to an administrative error.
STOCKHOLDER PROPOSALS AND NOMINATIONS FOR 2024 ANNUAL MEETING
Stockholders may submit proposals appropriate for stockholder action at the 2024 Annual Meeting consistent with the requirements of Rule 14a-8 under the Exchange Act, all other rules of the SEC relating to stockholder proposals and our Bylaws.

Stockholder proposals not intended to be included in our proxy statement (including director nominations) may be brought before the 2024 Annual Meeting by filing a notice of stockholder’s intent to do so no earlier than January 24, 2024, and no later than February 23, 2024. The notice must include all of the information required to be set forth in any such notice by our Bylaws.
Stockholders who intend to submit director nominees for inclusion in our proxy materials for the 2024 Annual Meeting must comply with the requirements of proxy access as set forth in our Bylaws. The stockholder or group of stockholders who wish to submit director nominees pursuant to proxy access must deliver the required materials to us no earlier than November 14, 2023, and no later than December 14, 2023.
In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules (once effective), stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 24, 2023.

FORM 10-K, ANNUAL REPORT AND FINANCIAL STATEMENTS
A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, including the financial statements and the financial statement schedules, but without exhibits, is contained within our Annual Report which is available on our website at https://www.nisource.com/filings. We will mail a copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, including the financial statements and the financial statement schedules, but without exhibits, free of charge to any stockholder upon written request to NiSource Inc., c/o Corporate Secretary, 801 East 86th Avenue, Merrillville, Indiana 46410.
AVAILABILITY OF PROXY MATERIALS
In accordance with SEC rules, we are using the internet as our primary means of furnishing proxy materials to stockholders. Consequently, most stockholders will not receive paper copies of our proxy materials. We will instead send these stockholders a Notice of Internet Availability of Proxy Materials with instructions for accessing the proxy materials, including our Proxy Statement and Annual Report for the year ended December 31, 2022, and voting via the internet. The Notice of Internet Availability of Proxy Materials also provides information on how stockholders may obtain paper copies of our proxy materials if they so choose. This makes the proxy distribution process more efficient and less costly and helps conserve natural resources. If you previously elected to receive our proxy materials electronically, these materials will continue to be sent via email unless you change your election.
MULTIPLE STOCKHOLDERS SHARING THE SAME ADDRESS — “HOUSEHOLDING”
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering a single set of proxy materials addressed to those stockholders. This process, which is commonly referred to as “householding,” may potentially provide extra convenience for stockholders and cost savings for companies or the intermediary.
You may receive proxy materials through an intermediary who uses householding to deliver proxy materials. If so, a single copy of the proxy materials, including the Notice of Internet Availability of Proxy Materials, may be delivered to

multiple stockholders sharing an address unless the affected stockholder provides contrary instructions. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If this applies to you and you would prefer to receive separate copies of the proxy materials, including the Notice of Internet Availability of Proxy Materials, please notify your broker that you no longer wish to participate in householding. Additionally, you may direct your written request for a copy of the proxy materials to NiSource Inc., c/o Corporate Secretary, 801 East 86th Avenue, Merrillville, Indiana 46410, or you may request a copy by telephone at (877) 647-5990. If your broker is not currently householding (i.e., you received multiple copies of our Notice of Availability of Proxy Materials), and you would like to request delivery of a single copy, you should contact your broker and find out if this option is available to you.
