ELECTION OF DIRECTORS

ALLIANT ENERGY | 2021 Proxy Statement | 1

ELECTION OF DIRECTORS


Proposal One—ELECTION OF DIRECTORS

At our annual meeting of shareowners (Annual Meeting), three directors will be elected. The nominees for election are:


• Roger K. Newport			• Dean C. Oestreich			• Carol P. Sanders

Each nominee currently serves on our Board of Directors. If elected as directors, each of the nominees will serve until our Annual Meeting of Shareowners in 2024 or until his or her successor has been duly qualified and elected.

The nominees were selected by the Board of Directors on the recommendation of the Nominating and Governance Committee. The Nominating and Governance Committee is responsible for evaluating nominees for director and director candidates. The committee has criteria to ensure that the specific skills, qualifications and experiences necessary for the effectiveness of the Board of Directors are fully represented on the Board. In addition, the Nominating and Governance Committee strives to create a diverse Board of Directors as measured by the criteria of age, gender, ethnicity, tenure, skills, qualifications and experience. The following charts reflect the skills and qualifications and demographic information that the Board views as important when evaluating director nominees. Each director nominee also contributes other important skills, expertise, experience and personal attributes to the Board that are not reflected in the chart below.

ALLIANT ENERGY | 2021 Proxy Statement | 2

ELECTION OF DIRECTORS

The balance of tenure of our directors promotes experience and stability while also allowing for a broader understanding of the issues that can affect our business. Our more tenured directors provide deep historical perspective of our Company and our industry. Our newer directors provide fresh perspectives and benefit from the knowledge and experience of our more tenured directors. This optimal combination of experience, subject matter expertise and fresh perspectives ensures that our Board is able to provide oversight and guidance that is innovative, balanced and aligned with the Company’s purpose and strategy.

In fulfilling its responsibility to identify qualified candidates for membership on the Board of Directors, the Nominating and Governance Committee also considers, among other factors, the following attributes of candidates:

• Highest personal and professional ethics, integrity and values

• Highly accomplished in his or her respective field, with superior credentials and recognition and broad experience at the administrative and/or policy-making level in business, government, education, technology or public interest

• Ability to exercise sound business judgment

• Independence from any particular constituency and/or ability to represent all of our shareowners and commitment to enhance long-term shareowner value

• Relevant expertise and experience and the ability to offer advice and guidance to our Chief Executive Officer based on that expertise and experience

• Sufficient time available to devote to activities of the Board of Directors and to enhance his or her knowledge of our business

Biographies of the director nominees and continuing directors follow. The biographies list the key qualifications, skills and experience of each director nominee and continuing director that led to the Board’s conclusion that the person should serve. Each nominee and continuing director’s age is as of April 1, 2021.

Directors will be elected by a plurality of the votes cast at the meeting (assuming a quorum is present). Consequently, any shares not voted at the meeting, including as a result of broker non-votes, will not be counted as votes cast. The proxies solicited may be voted for a substitute nominee or nominees if any of the nominees is unable to serve, or for good reason will not serve, a contingency the Board of Directors does not currently anticipate.

We are a public utility holding company whose regulated utilities are Interstate Power and Light Company (IPL) and Wisconsin Power and Light Company (WPL). The composition of our Board of Directors is identical to the composition of the Boards of Directors of IPL and WPL.

Additional information regarding the selection process for members of the Board of Directors can be found starting on page 18.


þ			The Board of Directors recommends that you vote FOR the nominees for director.

CORPORATE GOVERNANCE

Corporate Purpose and Values

Our purpose at Alliant Energy is to serve customers and build strong communities. With our purpose, our Values are the foundation of our culture, guide our actions, and describe how we accomplish our strategy.

ALLIANT ENERGY | 2021 Proxy Statement | 9

CORPORATE GOVERNANCE

Ethical and Legal Compliance Policy

Our Board of Directors has adopted a Code of Conduct that serves as our code of ethics. We created our Code of Conduct to define our standards for workplace behavior and to provide guidance on what to do when faced with a difficult situation. These guidelines apply to all employees, at every level, including our Chief Executive Officer (CEO), Chief Financial Officer (CFO), and Chief Accounting Officer, as well as the members of our Board of Directors. The expectations laid out in the Code of Conduct are quite simple: make good choices and live our Values. Find our Code of Conduct at www.alliantenergy.com/investors under the Corporate Governance link. To comply with the disclosure requirements under Item 5.05 of Form 8-K, we will post any new amendments to, or waivers from our Code of Conduct here throughout the year.

Corporate Governance Guidelines

Our Board of Directors has adopted Corporate Governance Guidelines that outline how Directors can represent investor interests and oversee how the Company in fulfills its purpose. The Guidelines, in conjunction with the Board committee charters, establish processes and procedures to help ensure effective and responsive governance by the Board. Our Corporate Governance Guidelines are posted at www.alliantenergy.com/investors under the Corporate Governance link.

Director Independence

Our Corporate Governance Guidelines provide that at least 75% of the members of the Board of Directors must be independent directors under the applicable rules of The Nasdaq Stock Market LLC (Nasdaq). The Audit, Compensation and Personnel, and Nominating and Governance Committees must be composed only of independent directors.

The Board of Directors evaluates directors’ independence under the applicable Nasdaq rules, including the categorical standards of independence provided by Nasdaq rules.

The Board of Directors also considers certain other factors to determine a director’s independence. During 2020, Mr. Allen served as an executive officer of a company that is a customer of IPL; Mr. Garcia served as an executive officer of a company that is a customer of WPL; and Mr. O’Toole served as a director of a company that is a customer of WPL. These customer relationships do not constitute a material relationship under the Nasdaq rules cited above or the Securities and Exchange Commission (SEC) rules governing related-person transactions discussed below. However, the relationships were evaluated under the applicable Nasdaq rules and applicable SEC rules. The Board of Directors determined that the relationships did not impair the independence of Mr. Allen, Mr. Garcia or Mr. O’Toole.

The Board of Directors adopted resolutions that affirm that each of Mr. Allen, Mr. Garcia, Ms. McAllister, Mr. Newport, Mr. O’Toole, Mr. Oestreich, Ms. Sanders, Ms. Whiting, and Ms. Evanko while she was a member of the Board of Directors, has no material relationship with the Company that would impair his or her independent judgment as a director and, therefore, is independent in accordance with Nasdaq rules.

Majority Voting in Uncontested Director Elections

Under our Corporate Governance Guidelines, if a director nominee in an uncontested election (i.e., an election where the number of nominees is not greater than the number of directors to be elected) receives more WITHHELD votes than FOR votes, the director nominee is required to offer his or her resignation to the Chair of the Board of Directors following certification of the shareowner vote. The Nominating and Governance Committee shall consider such resignation and make a recommendation to the Board whether to accept or reject the tendered resignation, or whether other action

should be taken. The Board shall act on the tendered resignation, taking into account the Nominating and Governance Committee’s recommendation and all other factors deemed relevant, and publicly disclose (by a press release, a filing with the SEC or other broadly disseminated means of communication) its decision regarding the tendered resignation within 90 days from the date of final certification of the shareowner vote. The director who has tendered a resignation pursuant to this provision shall not participate in the Nominating and Governance Committee’s or the Board’s deliberations or decision with respect to the tendered resignation.

Attendance and Performance Evaluations

Our Board of Directors held eight joint (Alliant Energy, IPL and WPL) Board meetings in 2020. Each director attended at least 75% of the aggregate number of meetings of the Board of Directors and Board committees on which he or she served during his or her tenure on the Board.

The Board of Directors and each Board committee conduct performance evaluations annually to determine their effectiveness and suggest improvements. In addition, the Compensation and Personnel Committee evaluates the performance of the CEO on an annual basis.

ALLIANT ENERGY | 2021 Proxy Statement | 10

CORPORATE GOVERNANCE

Members of our Board of Directors are expected to attend our Annual Meeting of Shareowners. All members of our Board of Directors were present for our 2020 Annual Meeting.

Related-Person Transactions

We have adopted a written policy regarding related-person transactions. The policy provides that we will annually disclose information regarding related-person transactions as required by regulations of the SEC to be disclosed, or incorporated by reference, in our Annual Report on Form 10-K. For purposes of the policy “related-person” means any of our directors or executive officers, nominees for director and any member of the immediate family of such person.

A related-person transaction is generally a transaction in which: (1) we are a participant; (2) the amount involved exceeds $120,000; and (3) a related-person has a direct or indirect material interest. A related-person transaction does not include:

• The payment of compensation by us to our executive officers, directors or nominees for director

• A transaction in which the interest of the related-person arises solely from the ownership of our shares and all shareowners receive the same benefit on a pro-rata basis

• A transaction in which the rates or charges involved are determined by competitive bids, or that involves the rendering of services as a common or contract carrier or public utility at rates or charges fixed and in conformity with law or governmental authority

• A transaction that involves services as a bank, transfer agent, registrar, trustee under a trust indenture, or similar services

Furthermore, a related-person is not deemed to have a material interest in a transaction if the person’s interest arises only:

•From the person’s position as a director of another party to the transaction

•From the ownership by such person and all other related-persons, in the aggregate, of less than a 10% equity interest in another entity (other than a partnership) that is a party to the transaction

•From such person’s position as a limited partner in a partnership in which such person and other related-persons have an interest of less than 10%, and the person is not a general partner of, and does not hold another position in, the partnership

•From both such director position and ownership interest

Pursuant to the policy, each of our executive officers, directors and nominees for director is required to disclose to the Nominating and Governance Committee certain information regarding related-person transactions for review, approval or ratification by the committee. If possible, they should disclose the related-person transaction to the committee before the related-person transaction occurs. In any event, they must disclose the transaction as soon as practicable after the transaction is effected or they become aware it.

The Nominating and Governance Committee will decide whether to approve or ratify the related-person transaction based on whether the transaction is contrary to the best interests of the Company. The committee may take into account the effect of a director’s related-person transaction on such person’s status as an independent member of our Board of Directors and eligibility to serve on Board committees under SEC and Nasdaq rules.

We had no related-person transactions since the beginning of 2020, and no related-person transactions are currently proposed.

Risk Oversight

Our Corporate Governance Guidelines provide that the Board of Directors is responsible for overseeing and understanding our purpose, vision and mission, strategic plans, overall corporate risk profile, risk parameters,

annual operating plans and annual budgets, and for monitoring whether these plans are being implemented effectively. We utilize an enterprise risk management program designed to identify, communicate and manage significant risks in a structured framework. The Audit Committee oversees the Company’s enterprise risk management program. It annually reviews an extensive risk inventory, which identifies enterprise risks by category, assigns values and includes rankings to identify top risks, and includes management mitigation plans. The process also identifies management oversight assignments, internal audit coverage where applicable and board/committee oversight responsibilities.

Significant operational risks are the subject of regularly scheduled reports to the full Board of Directors or the appropriate Board committee. Senior management provides updates to the Board on information technology risks, including cybersecurity risks, at least twice per year.

The Compensation and Personnel Committee conducted an assessment of our compensation policies and practices in 2020. The result of this assessment is described in further detail under “Compensation and Personnel Committee Risk Assessment” in the Compensation Discussion and Analysis.

Environmental, Social and Governance Oversight

We recognize the importance that sustainability matters have on our operations, including environmental, social and governance (ESG) matters. These matters are represented by our Company Values to Act for tomorrow, Make things better and Care for others. The Nominating and Governance Committee is responsible for general oversight of ESG issues, including review and approval of our annual Corporate Responsibility Report. The committee oversees the

Company’s progress on important ESG topics, which include a broad range of issues handled by various

committees. The Board of Directors and Board committees have ESG responsibilities as follows.

CORPORATE GOVERNANCE

Shareowner Outreach

In 2020, we reached out to holders of approximately 50% of our outstanding shares, and held discussions with those who agreed to meet. Our outreach meetings generally included: discussions about composition of our Board of Directors; our strategy; ESG and sustainability issues; enhanced disclosures, including use of the Task Force on Climate-related Financial Disclosures and Sustainability Accounting Standards Board frameworks in the Corporate Responsibility Report; executive compensation matters, including setting metrics and the use of ESG metrics in incentive plans; diversity, equity and inclusion matters; governance matters; and our response to the COVID-19 pandemic. The Lead Independent Director, CEO, CFO, Vice President and Treasurer, and members of the Corporate Secretary, Legal and Investor Relations departments participated in a number of these discussions. Shareowner feedback and suggestions that we received were reported to the Board of Directors or relevant Board committee for consideration.

In addition, our top managers, including the CEO and CFO, regularly participate in investor and industry conferences throughout the year to discuss performance and share perspectives on Company and industry developments. We also offer channels for shareowners to contact the Board of Directors with any inquiry or issue.

Communication with Directors

Shareowners and other interested parties may communicate with the full Board of Directors, non-employee directors as a group, or individual directors (including the Lead Independent Director) by writing to our Corporate Secretary, who will post such communication directly to our Board of Directors’ confidential web portal.

Board of Directors Leadership Structure

Our Bylaws and our Corporate Governance Guidelines provide that the Board of Directors is responsible for selecting a Chair of the Board of Directors and a CEO. The Board regularly reviews the leadership structure. The board has determined that combining the roles of Chair and CEO continues to foster clear accountability and decision-making, and promote a consistent and accurate message to our investors, employees, customers and other constituencies. Under our Corporate Governance Guidelines, the Chair of the Nominating and Governance Committee is designated the Lead Independent Director when the positions of Chair of the Board and CEO are held by the same person.

Lead Independent Director

As the Chair of the Nominating and Governance Committee, Ms. Sanders is currently designated as the Lead Independent Director. The Lead Independent Director is recognized by management and the Board of Directors as a key position of leadership within the Board of Directors. Our Corporate Governance Guidelines provide that the Lead Independent Director will preside at regular executive sessions of the Board of Directors, without management participation, though our Corporate Governance Guidelines do not grant the Lead Independent Director any special authority over management. Our Lead Independent Director’s role also encompasses additional Board governance responsibilities.

Lead Independent Director Roles

• Communicating applicable information from executive session deliberations to the Chair and CEO

• Reviewing with the Chair and CEO items of importance for consideration by the Board of Directors

• Acting as principal liaison between the independent directors and the Chair and CEO on sensitive issues

• Discussing with the Chair and CEO important issues to assess and evaluate views of the Board of Directors

• Consulting with any or all of our independent directors at the discretion of either party and with or without the attendance of the Chair and CEO

• In conjunction with the Nominating and Governance Committee, recommending to the Chair and CEO the membership of the various Board committees and selection of the Board committee chairs

• In conjunction with the Nominating and Governance Committee, interviewing all director candidates and making recommendations to the Board of Directors on director nominees

• Mentoring and counseling new members of the Board of Directors to assist them in becoming active and effective directors

• In conjunction with the Nominating and Governance Committee, reviewing and approving the philosophy of, and program for, compensation of the independent directors

• Meeting with the CEO to discuss the CEO performance evaluation

ALLIANT ENERGY | 2021 Proxy Statement | 13

CORPORATE GOVERNANCE

We believe that the use of a Lead Independent Director has been effective for us and has greatly facilitated communication of important issues between the Board of Directors and the CEO.

Executive Sessions

The independent directors meet in executive session with no member of our management present at every regular meeting of the Board of Directors.

ALLIANT ENERGY | 2021 Proxy Statement | 14

The Compensation and Personnel Committee has engaged Pay Governance LLC as its independent external advisor to analyze the competitive level of executive compensation and provide information regarding executive compensation trends. The committee reviewed its relationship with Pay Governance and considered Pay Governance’s independence and the existence of potential conflicts of interest. The committee determined that the engagement of Pay Governance did not raise any conflict of interest or other issues that would adversely impact Pay Governance’s independence.

•Whether Pay Governance and its advisors provide other services to us

•The amount of fees we pay to Pay Governance as a percentage of Pay Governance’s total revenues

(1) Mr. Larsen is also an employee of the Company and received no additional compensation for his service on our Board of Directors, therefore he is not included in this table. Compensation received by Mr. Larsen for 2020 is shown in the Summary Compensation Table. Ms. Evanko served on the Board of Directors until January 27, 2021.

(2) The amounts shown in this column include the following aggregate dollar amounts deferred and the corresponding number of shares of common stock credited in our Alliant Energy Deferred Compensation Plan Company Stock Account by each of the following directors:

Susan D. Whiting	$19,750	373

(3) The amounts shown in this column represent above-market interest on non-qualified deferred compensation.

(4) The amounts in this column include payments made to charities through the Alliant Energy matching gift program. Infrequently, spouses and guests of directors accompany the directors on a corporate aircraft when the aircraft is already going to a specific destination for a business purpose at no aggregate incremental cost to the Company. No such travel occurred in 2020.

Retainer Fees

In 2020, all non-employee directors, each of whom served on the Boards of Directors of the Company, IPL and WPL, received an annual cash retainer for service on all Boards, payable quarterly in advance. The following table describes the annual cash retainer received for service in 2020 and the annual retainer that will be received for service in 2021, as well as other fees for director services. Fees for 2020 and 2021 were based on a review of market-based compensation for non-employee directors presented by the Compensation and Personnel Committee’s independent consultant.

ALLIANT ENERGY | 2021 Proxy Statement | 20

DIRECTOR COMPENSATION

Meeting Fees

In 2020, directors did not receive any additional compensation for attendance at Board or committee meetings. The same applies for 2021.

Expense Reimbursements

Pursuant to our directors’ expense reimbursement policy, we reimburse all directors for travel and other necessary business expenses incurred in the performance of their responsibilities for us. Committees are provided the opportunity to retain outside independent advisors, as needed. We also extend coverage to directors under our Directors’ and Officers’ Indemnity Insurance Policies.

Receipt of Fees in Stock

For fees paid in 2020, each director was encouraged to voluntarily elect to use a portion of his or her cash retainer to purchase shares of our common stock pursuant to our Shareowner Direct Plan, or to defer such amount through the Company Stock Account in the Alliant Energy Deferred Compensation Plan. For fees paid in 2021, directors were encouraged to use 55% of their cash retainer to purchase shares of our common stock through the Shareowner Direct Plan or the Alliant Energy Deferred Compensation Plan. A non-employee director may elect to receive, or the Nominating and Governance Committee may require that a non-employee director be paid, all or any portion of his or her annual cash retainer payment or other cash fees in the form of shares of common stock issued under our 2020 Omnibus Incentive Plan or a successor plan thereto.

Share Ownership Guidelines

Directors are required to be shareowners. The target share ownership level for non-employee directors is the number of shares equal to the value of two times the full annual retainer. Directors have five years after joining the Board of Directors to attain the ownership guideline. Shares held by directors in the Shareowner Direct Plan and the Alliant Energy Deferred Compensation Plan are included in the target goal. As of December 31, 2020, all of our current non-employee directors had met the target ownership level, with the exception of Mr. Newport, who became a director in 2018, and Mr. Garcia, who became a director in 2020. We continue to monitor the status of the target ownership levels and review them with the Board of Directors.

Alliant Energy Deferred Compensation Plan

Under the Alliant Energy Deferred Compensation Plan, directors may elect to defer all or part of their retainer fee to an Interest Account, Equity Account, Company Stock Account or Mutual Fund Account. Deferrals credited to the Interest Account receive an annual return based on the 10-year Treasury Bond Rate plus 1.50%. Deferrals credited to the Equity Account are treated as invested in an S&P 500 index fund. Deferrals credited to the Mutual Fund Account are treated as invested in a mutual fund or other investment vehicle offered under our Alliant Energy Corporation 401(k) Savings Plan as selected by the director. Deferrals credited to the Company Stock Account are treated as though invested in our common stock and are credited with dividend equivalents, which are treated as if reinvested in our common stock. Payments from our Alliant Energy Deferred Compensation Plan by reason of death or retirement may be made in a lump sum or in annual installments for up to 10 years at the election of the director. Payments from our Alliant Energy Deferred Compensation Plan for any reason other than death or retirement are made in a lump sum.

Directors’ Charitable Award Program

We maintain a legacy Directors’ Charitable Award Program in which only Ms. McAllister participates; this program was terminated for all directors who joined the Board after January 1, 2005. The purpose of the program is to recognize our directors’ interest in supporting worthy charitable institutions. Under the program, when a director dies, we will donate a total of $500,000 to up to five qualified charitable organizations selected by the individual director. The individual director derives no financial benefit from the program. We take all deductions for charitable contributions and fund the donations through life insurance policies on the director. Over the life of the program, all costs of donations and premiums on the life insurance policies, including a return of our cost of funds, will be recovered through life insurance proceeds on the director. In 2020, Ms. McAllister received no additional compensation for this program.

Alliant Energy Matching Gift Program

Directors are eligible to participate in the Alliant Energy Foundation, Inc. matching gift program, which is generally available to all employees and retirees. Under this program, the foundation matches 100% of charitable donations over $50 to eligible charities. In 2020, the amount of matching contributions was capped at $3,500 per year for each director.

HOW WE DETERMINE EXECUTIVE COMPENSATION

Our compensation vision is to provide compensation programs that promote the achievement of our purpose-driven strategy, align executives’ and employees’ interests with the success of the Company, and provide competitive compensation opportunities to attract, retain and motivate a highly talented executive team and workforce. Our philosophy is to design compensation programs that drive high performance and reward that performance competitively within our industry. We believe that everyone should clearly understand their compensation and how it connects to individual and shareowner value.

The objectives for our executive compensation program are as follows:

• Reward Strong Performance: motivate and reward executives to contribute to the achievement of our business objectives by aligning pay and performance through variable at-risk compensation

• Align Executives’ and Shareowners’ Interests: align executive officers’ interests with those of our shareowners by delivering a significant proportion of total compensation through equity, tying a portion of our long-term incentive pay directly to total shareowner return and requiring executives to own Company stock

• Maintain Consistency: drive sustainable performance and improvement by maintaining an appropriate level of executive compensation design consistency

• Provide Competitive Positioning: attract and retain the best possible personnel through competitive compensation that is comparable to that of similar companies but driving what is right for our strategy and stakeholders

ALLIANT ENERGY | 2021 Proxy Statement | 26

COMPENSATION DISCUSSION AND ANALYSIS

These compensation practices help us achieve our program objectives:

• Incentive-Based At-Risk Compensation: a substantial portion of our executive officers’ compensation is based on achievement of performance goals, including ESG-based goals, with long-term equity-based awards delivering a majority of the incentive-based pay

• Equity Ownership: executive officers have significant holdings of our common stock

• Minimized Systemic Risk-Taking: compensation programs are developed to properly mitigate unintended risk-taking, providing a mix of long-term and short-term compensation and using multiple performance criteria to determine awards

• Market Compensation: total aggregate compensation levels are reviewed against market compensation levels, which ensures that we provide a competitive pay opportunity

• Access to Retirement Programs: executive officers have access to retirement plans commonly in use among comparable companies, including deferred compensation plans, certain non-qualified retirement plans and 401(k) savings plans

The Compensation and Personnel Committee reconsiders these objectives and practices in its regular reviews of the executive compensation program.

COVID-19

The COVID-19 pandemic created unprecedented challenges for our Company, our customers, our communities and our employees in 2020. The Compensation and Personnel Committee regularly reviewed the Company’s strategic plan and goals in light of the impacts of COVID-19 with management and its independent consultant. Based on these reviews, the committee determined that the strategic plan remained appropriate, that executive and corporate goals remained relevant, and that changes to executive compensation in 2020 were not necessary due to COVID-19.

COMPENSATION DISCUSSION AND ANALYSIS

Our compensation components are weighted toward incentive-based compensation, as shown below:

Base Salary

The Compensation and Personnel Committee annually reviews and adjusts salaries based on changes in the market, responsibilities and performance against job expectations, strategic importance and experience and tenure. The Company is not contractually bound by employment or other agreements to pay particular levels of base salary to our executive officers, thereby affording flexibility in those determinations.

The following table sets forth the base salaries of each named executive officer as of the end of the 2020 and 2019 calendar years, as well as the percentage change from the prior year.


Named Executive Officer	2020 Base Salary	2019 Base Salary	Percentage Increase
John O. Larsen	$975,000	$900,000	8.3%
Robert J. Durian	$540,000	$500,000	8.0%
James H. Gallegos	$540,000	$525,000	2.9%
David A. de Leon	$375,000	$300,000	25.0%
Terry L. Kouba	$375,000	$300,000	25.0%

The salary increases reflect increased responsibilities, particularly for Mr. de Leon and Mr. Kouba, and efforts to keep total targeted compensation in line with market.

Short-Term (Annual) Incentive Pay

Executive officers participate in the Executive Performance Pay (EXPP) Plan that provides the opportunity for annual cash payments tied directly to the achievement of key financial and operational goals. The Compensation and Personnel Committee sets Company and individual goals guided by our purpose, our Values and our strategic plan. Company goals balance financial and operational goals to drive value for both our shareowners and customers.

The Compensation and Personnel Committee approved earnings per share as the financial goal to reward earnings growth. This aligns with our strategy to meet expectations of shareowners and was guided by our Value to Do the right thing – we keep our promise to deliver earnings growth. Operational goals related to customer experience, the environment and diversity were set to reward our commitment to our customers and ESG-related goals and reflect our corporate purpose to serve customers and build strong communities. The customer experience goals are linked to our customer-focused strategy and guided by our Value to Make things better for our customers and communities. The customer interaction target measures our efforts to make a simple, personalized experience for our customers. The System Average Interruption Duration Index (SAIDI) measures outage duration and the System Average Interruption Frequency Index (SAIFI) measures outage frequency. The emissions reduction goal is linked to our strategy to provide affordable, clean-energy solutions to our customers. It is guided by our Value to Act for tomorrow and measures our

ALLIANT ENERGY | 2021 Proxy Statement | 29

COMPENSATION DISCUSSION AND ANALYSIS

commitment to clean energy. Finally, our diversity goals support an inclusive culture and our Value to Care for others. Annual incentive-based payouts to our executive officers are based on achievement of these goals.

The Company goals for 2020 and our performance compared to those goals are shown below.


Goal	Percentage of Performance Pool	Target	Actual	Percentage Payment Toward Performance Pool
Consolidated EPS from Continuing Operations (EPS)	70%	EPS:(1) Threshold: $2.27 Target: $2.41 Maximum: $2.51	$2.44	80.5%
Customer Experience	7.5%	Customer Interaction Survey: Threshold: 7.66 Target: 7.78 Maximum: 8.18	8.48	11.3%
	3.75%	SAIDI: Threshold: 105 Target: 95 Maximum: 81	81	5.6%
	3.75%	SAIFl: Threshold: 1.03 Target: 0.93 Maximum: 0.79	0.74	5.6%

Diversity	3.75%	People of Color: Threshold: 5.2% Target: 5.4% Maximum: 5.6%	5.4%	3.7%
	3.75%	Women: Threshold: 25.9% Target: 26.6% Maximum: 27.3%	25.7%	0.0%
TOTAL	100.0%			118.0%

(1)2020 GAAP EPS from consolidated earnings from continuing operations was $2.47. Adjusted EPS in 2020 excludes a gain of $0.02 per share related to credit loss adjustments on a guarantee for an affiliate of Whiting Petroleum Corporation, a gain of $0.02 per share related to a tax valuation allowance adjustment, and a loss of $0.01 per share resulting from a settlement loss for the IPL retirement plan.

Each performance goal is measured independently of other goals. Company performance compared to the goals was 118% as shown in the chart above. Maximum Company performance is 150% of target.

Individual performance goals are set to drive an individual’s contribution to our strategic business imperatives. The goals can be both qualitative and quantitative and can vary for each executive officer. The Compensation and Personnel Committee may use individual performance to modify the amount of an incentive award earned by an executive officer. For 2020, the committee did not modify the awards of any named executive officer based on individual performance, and all payouts to the named executive officers for 2020 were calculated based on achievement of the Company goals shown above.

ALLIANT ENERGY | 2021 Proxy Statement | 30

COMPENSATION DISCUSSION AND ANALYSIS

Payment under the EXPP Plan is calculated as follows:

Each target payout percentage under the EXPP Plan is set by the Compensation and Personnel Committee based on survey data, tenure in a position, strategic importance and individual responsibilities. Target payouts as a percentage of base salary for 2020 are set forth below. They reflect slight increases from 2019 due to increased responsibilities and efforts to keep total targeted compensation in line with market.


Named Executive Officer			EXPP Plan Target Payout as a Percentage of 2020 Base Salary
John O. Larsen			110%
Robert J. Durian			75%
James H. Gallegos			65%
David A. de Leon			50%
Terry L. Kouba			50%

Based on achievement of goals under the EXPP Plan, each executive officer earned 118% of his or her target payment. Amounts paid in 2020 under the EXPP are provided in the Non-equity Incentive Plan Compensation column of the Summary Compensation Table.

The Compensation and Personnel Committee reviewed the short-term incentive plan and adopted a new environmental goal for 2021, which continues to measure our commitment to affordable, clean-energy solutions in line with our Value to Act for tomorrow. The 2021 Executive Short-Term Incentive Plan includes a goal to reward annual progress toward the Company’s long-term goal of a 50% reduction in CO2 emissions by 2030 from 2005 levels. The goal was adopted to replace the environmental goal in the current plan, which measures reductions of nitrogen oxide, sulfur dioxide and mercury, because reductions were fully achieved in 2020.

Long-Term (Equity) Awards

We award long-term equity compensation to focus our executive officers on building shareowner value, to retain management personnel and to align management interests with shareowner interests over a sustained period. In 2020, we granted long-term awards under our Amended and Restated 2010 Omnibus Incentive Plan to our named executive officers in three forms: performance restricted stock units, performance shares and restricted stock units. Long-term awards granted in 2021 were granted under our 2020 Omnibus Incentive Plan. The long-term equity awards in 2020 consisted of 35% performance restricted stock units, 35% performance shares and 30% restricted stock units, at target.

Performance restricted stock units reward absolute net income growth. Performance shares reward total shareowner return relative to our peer utility companies in the Edison Electric Institute (EEI) Stock Index. These long-term equity awards are forfeited if threshold results are not achieved during the applicable performance period. Restricted stock units vest based on continued service and enhance retention of management personnel and align our executive officers’ long-term financial interests to the long-term financial interests of our shareowners. These long-term equity awards are forfeited if the executive officer voluntarily leaves the Company (other than for retirement) or is terminated for cause during the time-vesting period. Currently, we do not issue stock options, do not have any outstanding stock options and do not anticipate issuing stock options. Below is a summary of the 2020 long-term awards.

Target payouts as a percentage of base salary for 2020 are set forth below. They reflect increases from 2019 due to increased responsibilities and efforts to keep total targeted compensation in line with market.


Named Executive Officer			2020 Target Long-Term Equity Grant Value as a Percentage of Base Salary
John O. Larsen			350%
Robert J. Durian			185%
James H. Gallegos			145%
David A. de Leon			85%
Terry L. Kouba			85%

The Compensation and Personnel Committee considers survey data, tenure in a position, strategic importance, individual responsibilities and the competitiveness of the total compensation package when setting the long-term incentive pay target. The dollar value of the long-term equity awards are determined prior to the grant date, and we grant the number of target units necessary to approximate that dollar value based on the fair market value of our share price on the grant date.

Performance Restricted Stock Units

Performance restricted stock units are intended to reward absolute long-term growth. Vesting of the performance restricted stock units is based on achieving a cumulative net income growth target over a three-year performance period as follows:


Three-Year Cumulative Consolidated Net Income from Continuing Operations Growth			Percentage of Target Value Payout
7%			200%
6%			150%
5%			100%
4%			50%
Below 4%			0%

Vesting at target requires 5% compounded annual growth, which is based on the successful and timely execution of our strategic plan. The target is calculated based on achieving a cumulative consolidated net income target over the performance period, excluding certain items as permitted by the Amended and Restated 2010 Omnibus Incentive Plan, such as charges for reorganizing and restructuring, discontinued operations, asset write-downs, gains or losses on the disposition of an asset or business, mergers, acquisitions or dispositions and unusual or non-recurring items of gain or loss, in each case, as identified in the Company’s audited financial statements or periodic reports. Performance restricted stock units granted in 2020 will vest at target if our cumulative consolidated net income from continuing operations over the performance period totals $1,879.5 million. Performance restricted stock unit payouts are capped at 200% of the target payout. Performance restricted stock units are paid in Company stock.

Any dividend equivalents credited on performance restricted stock units are treated as reinvested, but are not payable to the participant until the performance target is met and vesting is completed.

Performance restricted stock units have double-trigger acceleration upon a change in control. Upon a change in control, the awards vest at target and are valued based on the Company’s stock price as of the date immediately preceding the

ALLIANT ENERGY | 2021 Proxy Statement | 32

COMPENSATION DISCUSSION AND ANALYSIS

change in control date. The awards are paid at the end of the three-year vesting period provided the executive is still employed by the Company or had a qualifying termination event.

Performance restricted stock units granted in 2018 (performance period ended on December 31, 2020) had a net income target calculated based on achieving a compounded annual growth rate of 5% for a two-year period over projected 2018 consolidated net income from continuing operations, excluding certain items described above as permitted by the Amended and Restated 2010 Omnibus Incentive Plan. Adjusted net income for the period ended December 31, 2020 was $578 million, which exceeded 7% three-year compounded annual growth of consolidated net income from continuing operations. As a result, our named executive officers earned 200% of the target award for the 2018-2020 performance period. Additional information about the payout of the performance restricted stock units for the 2018-2020 performance period is provided in the 2020 Option Exercises and Stock Vested table.

Performance Shares

Performance shares are intended to reward Company performance relative to our peers in the EEI Stock Index. Vesting of the performance shares is based on our relative total shareowner return over a three-year performance period as follows:


Three-Year Total Shareowner Return Relative To EEI Stock Index			Percentage of Target Value Payout
90th percentile or greater			200%
80th percentile			175%
70th percentile			150%
60th percentile			125%
50th percentile			100%
45th percentile			75%
40th percentile			50%
Below 40th percentile			0%

The total shareowner return calculation represents the cumulative return for the three-year performance period reflecting price appreciation and reinvested dividend payments. Performance shares pay at target if our relative total shareowner return over three years is equal to the median performance of a specific peer group selected by the Compensation and Personnel Committee. The committee selected the EEI Stock Index as the peer group for the 2020 grants of performance shares as in previous years. We believe the comparison to the EEI Stock Index appropriately assesses our performance relative to other publicly traded utilities. Performance share payouts are capped at 200% of the target payout.

Performance shares granted in 2018 were paid in shares of our common stock, cash or a combination of our common stock and cash, at the executives’ election. If the named executive officer chose to take the payment in cash, the amount of the payout was determined by multiplying the number of shares earned by the stock value on a date chosen by the Compensation and Personnel Committee. The committee chose this date in advance of issuing shares under the program, and it is typically the date immediately prior to payment. Performance shares granted in 2019 and 2020 are paid in Company stock only.

Any dividend equivalents credited on performance shares are treated as reinvested, but are not payable to the participant until the performance target is met and vesting is completed.

Performance shares have double-trigger acceleration upon a change in control. Upon a change in control, the awards vest at the performance level based on the Company’s performance as of the date immediately preceding the change in control date. The awards are paid at the end of the three-year performance period provided the executive is still employed by the Company or had a qualifying termination event.

The total shareowner return for the 2018 performance share grant (performance period ended on December 31, 2020) ranked at the 79th percentile relative to the peer group. As a result, our named executive officers earned 172.5% of the target award for the 2018-2020 performance period. Additional information about the performance share payouts for the 2018-2020 performance period is provided in the 2020 Option Exercises and Stock Vested table.

ALLIANT ENERGY | 2021 Proxy Statement | 33

Restricted Stock Units

Restricted stock units are intended to align management interests with shareowner interests and retain management personnel. Restricted stock units are time-vesting awards for which forfeiture restrictions lapse in a single installment after three years, subject to continuous employment. Restricted stock units granted in 2018 were paid in shares of our common stock, cash or a combination of our common stock and cash, at the executives’ election. If the named executive officer chose to take the payment in cash, the amount of the payout was determined by multiplying the number of shares earned by the closing price on the last day of the vesting term of the restricted stock units. Restricted stock units granted in 2019 and 2020 are paid in Company stock only.

Any dividend equivalents credited on restricted stock units are treated as reinvested, but are not payable to the participant until vesting is completed.

Restricted stock units have double-trigger acceleration upon a change in control. Upon a change in control, the awards vest at the value based on the Company’s stock price as of the date immediately preceding the change in control date. The awards are paid at the end of the three-year vesting period provided the executive is still employed by the Company or had a qualifying termination event.

Additional information about the restricted stock unit payouts for the 2018-2020 vesting period is provided in the 2020 Option Exercises and Stock Vested table.

Retirement and Other Benefits

We offer retirement and other benefit programs to our named executive officers that are consistent with those of our peers. We provide these benefits to remain competitive with the general market for executive officers. The benefit programs are designed to be competitive in attracting, retaining and motivating our named executive officers by providing competitive retirement benefits and incentivizing the promotion of the Company’s and shareowners’ interests over a long time horizon. A brief description of the plans is set forth in the table below.

ALLIANT ENERGY | 2021 Proxy Statement | 34

COMPENSATION DISCUSSION AND ANALYSIS


Benefit			Description
Alliant Energy Deferred Compensation Plan (AEDCP)(1)			Enables participants to defer up to 100% of base salary and annual incentive pay on a pre-tax basis and to receive earnings or incur losses on the deferrals until the date of distribution. The shares of Company common stock identified as obligations under the AEDCP are held in a rabbi trust.
Alliant Energy Cash Balance Pension Plan(2)			Offers flexible payment options and steady growth of retirement funds. The Cash Balance Pension Plan was frozen for participants effective August 2, 2008. Employees hired after December 25, 2005 are not eligible to participate.
Alliant Energy Corporation 401(k) Savings Plan			Provides for a match of $0.50 on each dollar for the first 8% of compensation contributed to the 401(k) Savings Plan account by the participants up to the IRS maximum. In addition, we contribute a percentage of participants’ salaries to their 401(k) accounts. The amount of the Company contribution ranges from 4% to 6% of a participant’s salary, depending on the participant’s age and number of years of service at the Company.
Alliant Energy Excess Retirement Plan(2)			Provides the benefit that the participants would have earned under the Cash Balance Pension Plan and the Alliant Energy Corporation 401(k) Savings Plan but for statutory limitations on employer-provided benefits imposed on those tax-qualified plans and accruals earned on their deferrals into the AEDCP.
Alliant Energy Supplemental Retirement Plan (SRP)(2)			Generally provides retirement compensation in addition to the benefits provided by the Cash Balance Pension Plan and 401(k) Savings Plan, which are limited by the Internal Revenue Code of 1986 (which we refer to as the tax code), and the Alliant Energy Excess Retirement Plan. Generally payable only if the executive remains with us until retirement, disability or death. We do not anticipate providing SRP benefits to executives hired or promoted in 2013 or thereafter.

(1) See 2020 Non-qualified Deferred Compensation below for more information regarding the AEDCP.

(2) See 2020 Pension Benefits below for more information regarding the Alliant Energy Cash Balance Pension Plan, the Excess Retirement Plan and the SRP.

The Compensation and Personnel Committee reviews benefit programs on a periodic basis to determine effectiveness and identify any necessary changes. Based on market data showing a trend away from SRPs, we do not anticipate providing SRP benefits to executives hired or promoted in 2013 or thereafter. The committee does not believe this change will inhibit our ability to attract and retain executive officers.

We provide limited perquisites to our named executive officers. Our named executive officers are eligible for executive physicals, reimbursement of financial planning expenses and long-term disability insurance which are in excess of the benefits provided to our other non-executive employees. The Compensation and Personnel Committee recognizes that the CEO’s job duties require significant travel and he is, therefore, permitted to use a corporate aircraft. From time to time, a family member or members may accompany the CEO on business trips. For that reason, the Compensation and Personnel Committee established guidelines for personal use of the corporate aircraft. Under those guidelines, the CEO is permitted up to 40 hours of personal use of corporate aircraft each year.

Post-Termination Compensation

Key Executive Employment and Severance Agreements

We currently have in effect Key Executive Employment and Severance Agreements (KEESAs) with our executive officers, including our named executive officers, and certain other key employees, which provide for severance benefits under certain circumstances following a change in control. Benefits under the KEESAs are paid if: (1) a change in control occurs and (2) a loss of employment occurs under certain circumstances within 180 days prior to the change in control or two years after the change in control. This double-trigger mechanism ensures that only those executives adversely affected by a change in control will receive benefits under the KEESA. The cash termination benefit under the KEESA is up to two times the sum of: (i) the officer’s annual base salary and (ii) the greater of the officer’s target annual incentive pay for the year in which the termination date occurs, or the officer’s annual incentive pay in the year prior to the change in control. We do not offer severance arrangements with executive officers that provide a multiplier greater than two.

The KEESAs are generally designed to avoid the adverse effects of Section 280G of the tax code. Each KEESA provides that if any portion of the benefits under the KEESA or under any other agreement would constitute an excess parachute payment for purposes of the tax code, the executive officer may receive the greater, on an after-tax basis, of either a payment $1 less than the maximum amount he or she may receive without becoming subject to the 20% excise tax or the fully calculated payment subject to applicable excise taxes, for which the executive officer would be personally responsible. None of the KEESAs have Section 280G tax gross-up provisions.

ALLIANT ENERGY | 2021 Proxy Statement | 35

COMPENSATION DISCUSSION AND ANALYSIS

We believe that the level of the benefits provided by the KEESAs to each executive officer reflects the appropriate amount of compensation necessary for our executive officers to consider our shareowners’ interests without potential influence of their personal interests. We believe the security afforded by the KEESAs will help the executives to remain focused on business continuity and will reduce the distraction of the executive’s reasonable concerns regarding future employment during the uncertainty of a proposed change in control transaction.

Executive Severance Plan

We also maintain the executive officer severance benefit plan, which compensates an executive officer in the event that his or her position is eliminated or significantly altered. As with our KEESA benefit, our executive officer severance benefit plan is designed to enable executives to remain focused on our business without undue personal concerns over job security. The plan provides for:

•Severance pay equal to one year’s annual base salary

•Up to 18 months of COBRA coverage or participation in our subsidized retiree medical insurance program if eligible (six months of which are paid by us)

•Outplacement services and/or tuition reimbursement of up to $10,000

•Access to our employee assistance program

Eligibility for benefits under this plan is conditioned upon an executive executing a severance agreement and release form. All severance packages of executive officers are approved by the Compensation and Personnel Committee. We believe our executive severance plan is consistent with industry-wide standards.

Employment Agreements and Separation Arrangements

We do not have any other employment agreements or separation arrangements with our executive officers.

Process for Setting Executive Compensation


Entity			Role
Compensation and Personnel Committee			The Compensation and Personnel Committee reviews and sets each component and level of compensation for the Company’s named executive officers and other executive officers. The Compensation and Personnel Committee’s responsibilities include: • Review and approve executive officers’ compensation packages • Review and approve corporate incentive goals and objectives relevant to compensation • Evaluate individual performance results in light of these goals and objectives The Compensation and Personnel Committee is made up of independent directors and meets regularly in executive sessions without management present. The committee is supported in its work by the human resources staff and by the committee’s outside consultant.
Chief Executive Officer			The CEO recommends to the Compensation and Personnel Committee the level of compensation for the Company’s named executive officers and other senior Company executives, other than himself. The CEO considers the following factors when making his recommendations: • Executive performance • Tenure • Strategic importance • Internal pay equity • Market data, as discussed below • Information provided by the Company’s human resources staff The CEO is present and available to the Compensation and Personnel Committee during their meetings with respect to the compensation of the Company’s named executive officers and other executive officers. However, the committee discusses and determines the CEO’s compensation in executive session.
Independent Compensation Consultant			The Compensation and Personnel Committee engaged Pay Governance LLC as its independent external advisor. The committee receives data, analyses and support from Pay Governance. During 2020, Pay Governance participated in committee meetings, analyzed the competitive level of compensation for each of the named executive officers and provided information regarding executive compensation trends. Pay Governance reports solely to the committee and meets with the committee at each meeting in executive session.
Market Data			Each year, Pay Governance prepares a market compensation analysis based on companies of similar size in terms of revenue, including those in the energy services industry and in general industry. This analysis assists the Compensation and Personnel Committee in establishing executive officer compensation levels to allow us to remain competitive in our market. The market data used in 2020 included two surveys: • Willis Towers Watson’s 2019 General Industry Executive Compensation Database, which includes pay data for approximately 1,000 general industry companies • Willis Towers Watson’s 2019 Energy Services Industry Executive Compensation Database, which includes pay data for nearly all U.S. utilities. The Compensation and Personnel Committee used equally blended general industry data and energy industry data to determine the market reference point used for corporate positions, which in 2020 were held by Mr. Larsen, Mr. Durian and Mr. Gallegos. Energy industry data was used as a secondary market reference point for these positions. Energy industry data was used as the sole market reference point for utility-specific operating positions, such as those held by Mr. de Leon and Mr. Kouba. The Compensation and Personnel Committee considered only aggregate data from these broad-based surveys and did not select any individual companies for comparison. Survey information was size-adjusted using regression analysis to correspond to each officer’s scope of responsibility. The survey data was updated to January 2020 using a 3.1% annual update factor based on projected 2020 salary increases. The survey data provides market reference points at the 25th, 50th and 75th percentile for each executive officer’s compensation components and total compensation. Generally, total aggregate compensation that falls within 15% of the median market reference point is considered to be at target. The aggregate total targeted compensation for all named executive officers fell within 15% of the applicable market reference point in 2020.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Stock Ownership Requirements

We require executives to own a certain number of shares of our common stock to further align the executives’ interests with those of our shareowners. The stock ownership guidelines are:


Officer Level			Stock Ownership Guideline
Chief Executive Officer			6 times base salary
President			4 times base salary
Executive Vice President			3.5 times base salary
Senior Vice President			3 times base salary
Vice President			1.5 times base salary

The required number of shares for each executive is determined by taking the preceding multiples of the executive’s base salary and dividing that amount by the closing price of our common stock as of: (i) January 2, 2019, (ii) the date of hire, or (iii) the date of promotion to a higher level of ownership requirement, whichever is later. We round that number to the nearest 500-share increment. The number of shares an executive is required to hold will not change unless the executive is promoted. Setting the required number of shares this way mitigates the effect of short-term volatility on compliance caused by changes in our stock price and by changes in salary.

Shares held outright, vested restricted stock units, earned performance shares, earned performance restricted stock units, unvested restricted stock units that vest based solely on the passage of time, shares held in our AEDCP and shares held in the Alliant Energy Corporation 401(k) Savings Plan count toward the stock ownership requirement. Unearned performance restricted stock units and unearned performance shares do not count for this purpose.

Executives have five years from the date of their first long-term equity grants after the later of their hire date, or the date they were promoted into a position with a higher multiple, to achieve their goals. Executives are required to hold 100% of the after-tax value of vested performance restricted stock units until the stock ownership guideline is met. Executives who have not met their stock ownership level after five years are required to retain 100% of the after-tax value of vested long-term equity awards until the share ownership requirement is met. The Company has not issued any stock options so there is no requirement to hold stock options after exercise. Our CEO retains the right to grant special dispensation for hardship, promotions or new hires.

All of our current named executive officers who have held their current positions for five years are in compliance with the stock ownership guidelines. The named executive officers who have been in their positions for less than five years, including our CEO, are on track to achieve the above ownership goals. The shares owned by our named executive officers are shown in the Ownership of Voting Securities table.

Clawback Policy

The Compensation and Personnel Committee adopted a clawback policy that applies to all cash and equity-based incentive compensation. Under the clawback policy, the committee will recoup compensation paid under the Company’s cash and equity incentive plans if it determines that such compensation was based on the achievement of financial or other results that were subsequently restated due to material noncompliance of the Company with any financial reporting requirement under the federal securities laws, and due in whole or in part to gross negligence, intentional misconduct or fraud of a current or former executive officer. If, in the committee’s view, the incentive-based compensation would have been materially lower if it had been based on the restated results, the committee will, to the extent permitted by applicable law, seek recoupment from that executive officer of any excess incentive compensation.

Prohibition on Hedging and Pledging

We prohibit the use of any hedging or similar transactions related to our shares by our executive officers and directors. We prohibit all insiders from trading in puts, calls, options or other derivative securities related to the Company’s securities. Other hedging transactions, such as short sales, zero-cost collars, prepaid variable forward sale contracts, equity swaps or similar transactions are also prohibited. Insiders are further prohibited from pledging Company securities. Insiders include all executive officers, all members of the Board of Directors and designated employees who receive material nonpublic information in the regular course of their duties.

Compensation and Personnel Committee Risk Assessment

In December 2020, the Compensation and Personnel Committee reviewed an assessment presented by management of our general compensation policies and practices for all employees, including our non-regulated businesses, to evaluate whether risks arising from these policies and practices were reasonably likely to have a material adverse effect on us.

ALLIANT ENERGY | 2021 Proxy Statement | 39

COMPENSATION DISCUSSION AND ANALYSIS

Based on this assessment, the committee concluded that our compensation policies and practices are not reasonably likely to have a material adverse effect on the Company and did not recommend or implement any material changes in 2020. The committee believes that the following features of our policies and practices serve to mitigate material risks arising from our compensation policies and practices:

• A mix of annual and long-term incentive-based awards to provide an appropriate balance of short- and long-term risk and reward horizons

• A variety of performance metrics for incentive awards to avoid excessive focus on a single measure of performance

• Caps on incentive awards to reduce incentives to take short-term or inappropriately risky measures to increase payouts in any given year

• Review of our compensation programs for reasonableness by our state utility commissions to mitigate risk

• Clawback policies that provide us with the ability to recoup annual and long-term incentive awards under appropriate circumstances

• Stock ownership requirements for executives, including our named executive officers, that help to focus our executives on long-term stock price appreciation and sustainability

• Robust compensation governance practices

Role of Tax Considerations

Section 162(m) of the tax code limits the tax deductibility of compensation paid to our CEO and certain other executive officers to $1 million per person in any taxable year. Prior to changes to the tax code in December 2017, this limit did not apply to compensation that qualified as performance-based under Section 162(m). Effective for taxable years beginning after December 31, 2017, this exception has been repealed, unless the compensation qualifies for transition relief. As a result, from and after January 1, 2018, compensation to our named executive officers in excess of $1 million per year generally will not be deductible, even if performance-based.

The Compensation and Personnel Committee considers whether compensation will be deductible for federal tax purposes but, consistent with past practice, retains the flexibility and discretion to authorize compensation that will not be deductible. This flexibility is necessary to achieve elements of the Company’s success that are in the best long-term interests of the Company and its shareowners, such as attracting and retaining talented executives and rewarding achievement of key corporate goals.

Response to Non-Binding 2020 Say-on-Pay Shareowner Vote

At the Company’s 2020 Annual Meeting of Shareowners, shareowners approved the say-on-pay proposal with 97.6% of the votes cast in favor of the proposal. The say-on-pay proposal is an advisory, non-binding resolution relating to the compensation of our named executive officers. We interpret the voting results as support that our executive compensation program and practices are reasonable and well aligned with shareowners’ interests. Notwithstanding this vote of confidence expressed by our shareowners, the Compensation and Personnel Committee and management continue to review the Company’s executive compensation program and related disclosure with the assistance of outside compensation consultants and outside counsel to identify any potential changes that might augment shareowner value.

CONCLUSION

The Compensation and Personnel Committee is provided with appropriate information and reviews all components of our CEO’s and other executive officers’ compensation. Based on this information, the committee seeks to implement executive compensation that is appropriately tied to the performance of the Company and executives on behalf of shareowners, employees and customers.
