To Our
Valued
Investors

On behalf of our Board of Directors, it is our privilege to invite you to attend the 2022 Annual Meeting for Steel Dynamics, Inc. to be held on Thursday, May 5, 2022 at 9:00am Eastern Time in the Fort Wayne Country Club, 5221 Covington Road, Fort Wayne, Indiana, 46804.

On behalf of everyone at Steel Dynamics, I thank our loyal customers, vendors, communities and shareholders for their continued support of our company. My heartfelt thanks to our extraordinary team members for your passion, innovation, and dedication to excellence. The entire Steel Dynamics team delivered an outstanding performance during 2021. Our strategic growth and market positioning over the last several years were integral to our performance. We achieved numerous milestones and performed at the top of our industry both operationally and financially.

On almost every measure, our 2021 performance was a record year. Our steel and steel fabrication operations achieved record product pricing and demand, increasing 2021 revenues to a record $18.4 billion. Each of our three primary operating platforms achieved record annual earnings, resulting in record consolidated operating income of $4.3 billion and record net income of $3.2 billion.

We generated record cash flow from operations of $2.2 billion during 2021. We ended 2021 with strong liquidity of $2.4 billion, while at the same time meaningfully growing our business through significant organic growth investments, maintaining a positive cash dividend profile and executing on our share repurchase program. We have a firm foundation for our continued long-term, strategic growth and ongoing value creation.

Our performance is a testament to the passion, commitment and spirit of excellence that drives our teams. Across the company, our teams achieved best in-class performance, while maintaining a focus to keep each other healthy and safe. I am proud to work alongside each of them.

Based on our confidence in the consistency and strength of our cash generation capabilities, we have consistently grown our cash dividends to shareholders in alignment with our structural growth initiatives, maintaining a positive cash dividend growth profile. From 2017 to 2021, our cash dividend increased 86%, and based on our recent Sinton Steel Mill startup, we increased our first quarter 2022 cash dividend by an additional 31%, recognizing the increase in our through-cycle cash flow based on this transformational investment.

As an important and flexible shareholder distribution complement to our cash dividend, we also actively utilize our share repurchase programs in periods of exceptionally strong cash generation, taking into consideration our strategic growth strategy. As such, from 2016 to 2021, we repurchased $2.3 billion, or 24%, of our common stock, and in February 2022, our board of directors approved an additional share repurchase authorization of $1.25 billion.

Our Resources

Our commitment to all aspects of sustainability is embedded in our founding principles — valuing our people, our partners, our communities and our environment. These strategic principles drive long-term value creation for all of us.

2 2022 Proxy Statement | Steel Dynamics, Inc.

TABLE OF CONTENTS

2021 was a record-breaking year at each of our three primary operating platforms thanks to the passion and dedication of our teams.

The health and safety of our people is our number one value and primary focus. Nothing surpasses the importance of each individual team member. Safety is an integral part of our culture, and we must collectively ensure every person is personally engaged in sustaining a safe workplace for themselves, their team members, and their families.

We are also committed to operating our business in an environmentally responsible manner and have been since our founding. We only use electric arc furnace (EAF) technology — which emits a fraction of the greenhouse gases (GHG) and uses a fraction of the energy of traditional steelmaking. We have always been, and continue to be, a leader in the production of sustainable, lower-carbon emission steel products. We encourage the use of new technologies and processes to reduce our impact on the environment, including a strategic focus on carbon emissions mitigation with a goal for our steel mills to be carbon neutral by 2050. Our sustainability strategy is an ongoing journey, and we plan to use our entrepreneurial, innovative spirit to continue to be a leader in the industry.

Thank you for your trust.

Sincerely,

Mark D. Millett

Effective
Investor
Engagement

Consistent investor outreach is fundamental to our commitment to communication and transparency with our shareholders. We are committed to engaging with our investors on topics of importance to both them and us. We regularly reach out to our investor base. Our discussions cover topics based on publicly available information, such as strategic near and long-term growth initiatives, capital allocation philosophy and execution, sound governance practices, performance-based compensation philosophy, sustainable business model, renewable energy and climate initiatives, and similar matters. This process aids our Board to ensure issues important to our investors are appropriately understood and considered.

In addition to our regular shareholder engagement, we engage annually with a number of large institutional investors with dedicated governance teams to better understand their policies and concerns regarding environmental, social, and governance (“ESG”) practices and other important matters. During 2021, we reached out to our top institutional investors representing 50% of our outstanding shares, and a large number of these institutions accepted our offer to engage with us.

We communicate with our shareholders through various methods, including in person meetings, virtual meetings, investors conferences, and investor roadshows. Additionally, members of our senior leadership and investor relations team provided an open forum to each investor to discuss and comment on any matters they wish to discuss, including ESG practices, our long-term growth strategy, and capital allocation philosophy.

This outreach initiative assists us and our Board to fully understand the perspectives of our investors with respect to our ESG practices and other matters of importance to them. We also consult the publicly available policies of our major investors to better understand their views on ESG and other matters of importance to them. These meetings provide senior leadership and the Board with valuable insights into our investors’ perspectives.

Sustainability

Sustainability is a part of our long-term value creation strategy. We are dedicated to our people, our communities, and our environment. We are committed to operating our business with the highest integrity and have been since our founding.

Our commitment to all aspects of sustainability is embedded in our founding principles — valuing our teams, our partners, our communities, and our environment. These strategic principles drive long-term value creation for all of our stakeholders.

Environmental Performance

In 2021, we announced environmental goals which laid out our near-term and long-term greenhouse gas (GHG) emissions and renewable electric energy targets. Our steelmaking operations already meet the 2050 intensity targets under the Paris Agreement and its 2°C scenario 1 . Additionally, we are aligned with the Science Based Targets Initiative (SBTi) as we plan for our steel mills to meet the SBTi “well below 2°C” scenario target for combined Scope 1 and 2 emissions intensity by at least 2030 2 .

TABLE OF CONTENTS

We plan to continue to proactively address our environmental impact and to play a leadership role in innovative ways to reduce the impact of our operations on the environment.

We published our second comprehensive sustainability report in 2020, increasing disclosures and highlighting our strong environmental, social, and governance performance. We provided additional disclosures utilizing the Sustainability Accounting Standards Board’s (SASB) Iron & Steel Producers Standard, as well as the Global Reporting Initiative (GRI) framework.

During 2022, we published our sustainability update which provided updated and additional environmental and social data for 2020, as well as discussions on our key objectives and performance. Our sustainability reports and initiatives can be found at http://www.steeldynamics.com/Sustainability.

During 2022, we will publish our full sustainability report with plans to include disclosure consistent with the Task Force on Climate related Financial Disclosure (TCFD). We also expect to expand our disclosures by completing our first CDP Climate Change Questionnaire. Additionally, we plan to continue to report disclosures based on the Sustainability Accounting Standards Board and Global Reporting Initiative frameworks.

Health and Safety

The health and safety of our teams is and always will be our primary focus and core value. We want each individual to arrive at the workplace and return home safely each day — without injury. Health and safety is the first of our six pillars with a goal of zero — no accidents or injuries. This is achievable when we all work together.

The total recordable injury rate 1 for each of our platforms was better than industry benchmarks during 2021:

[MISSING IMAGE: tm223421d1-bc_steelpn.jpg]

During 2021, we continued to confront the global spread of COVID-19 with our team’s health and safety the primary objective and focus. We were proactive in early 2020 and implemented numerous practices and policies to protect our colleagues, many of which remain in place today. We will continue to monitor the situation and take every step to provide an environment that protects our people, their families, and our communities, while also serving our customers.

Inclusion and Diversity

Our people are the foundation of our success and are our most important resource. Our culture safeguards all people and requires each person to be treated fairly and with dignity. We have equal employment opportunity, no tolerance for harassment of any kind, respect for human rights, inclusion, and diversity — all of which focus on our expectations of treating every person with the utmost respect.

We recognize the value of having a business that reflects diversity of backgrounds and experiences. We work together as a unified team and respect each other as individuals. Our team-based compensation structure reinforces this philosophy. We strive to create a welcoming, open, and inclusive environment, ensuring the best ideas are heard and valued regardless of the position or the individual. We believe these ideals will continue to drive our success.

Our teams and colleagues represent the diversity of the communities where we live and work. Our employee population is representative of our industry and communities with 11% of our colleagues being female and 26% of our colleagues considered ethnically diverse. Additionally, of the eight individuals on our senior leadership team, one is female and one is ethnically diverse (Hispanic).

Executive
Compensation
Highlights

During 2021, we maintained our highly levered company-wide performance-based compensation structure, which is foundational to our entire compensation philosophy. The Compensation Committee did not make any adjustments to the compensation measurements or objectives of our executive officers, nor were any discretionary bonuses awarded. Our pay for performance programs continued to be based on the objective, measurable criteria that were established on the grant dates.

During 2022, the Compensation Committee will measure and assess a number of environmental, social, and safety metrics for evaluation and potential inclusion as performance measures for influence in our future executive compensation program. Among others, these metrics are expected to align with our focus on safety and our environmental goals, which we published in 2021.

Best Practices

We are committed to sound compensation practices that encourage long-term value creation and effective, sustainable use of our resources, as highlighted by the following items:

■	Highly levered company-wide performance-based compensation	■	“Double-trigger” change-in-control payments and benefits
■	Strong shareholder say-on-pay support with 93% voting in favor during 2021	■	No excise tax gross ups
■	Robust stock ownership requirements for all executive officers	■	Prohibit hedging and a severe limitation on pledging of Company stock
■	Clawback policy regarding executive compensation	■	Independent compensation consultant retained by the Compensation Committee

General
Information

Voting Information

On March 11, 2022, there were 189,518,389 shares of common stock outstanding. A list of shareholders entitled to vote at the meeting is available at our corporate office and will also be available at the meeting. Each share is entitled to one vote on each matter properly brought before the meeting. The presence, in person or by proxy, of the holders of a majority of the shares that are entitled to vote at the Annual Meeting is necessary to constitute a quorum for all purposes and all proposals.

We realize that most of you will not be able to attend the meeting in person, but it is very important that your shares be voted. We can only take action at the Annual Meeting, with respect to a particular matter, if a quorum, or majority, of the total number of shares of common stock outstanding and entitled to vote on that matter is present at the Annual Meeting. Therefore, unless you intend to come to the Annual Meeting and vote in person, or you intend to vote via the Internet or by phone, we are asking for your proxy to authorize the persons named in the proxy to be present at the Annual Meeting, to represent you, and to vote your shares at the Annual Meeting in accordance with your instructions.

If your shares of common stock are registered in your name with our transfer agent, Computershare Trust Company, N.A., you are the ‘shareholder of record’. If your shares are registered in the name of a broker, bank, custodian, or other nominee, that person is the shareholder of record and you are considered the ‘beneficial owner’.

TABLE OF CONTENTS

Voting Shares Held in Your Name
(Shareholder of Record)

If you are the record owner, regardless of whether you have received a paper copy of these proxy materials or only a Notice, you may vote your shares according to one of the four methods listed under “How to Vote Your Shares.” If you choose to vote by mail using your proxy card, your “proxy” — that is, the persons named in your proxy card — will then vote your shares as you have directed. If you send in your proxy and do not revoke it, your shares will be voted in accordance with your instructions. If you do not specify how you want your shares voted with respect to one or more proposals, your shares will be voted FOR each proposal.

Voting Shares Held by Brokers, Banks, Custodians or Other Nominees (Beneficial Owners)

Most shareholders arrange to have their shares held by brokers, banks, custodians or other nominees. In such case, your name, as the actual beneficial owner, does not appear in our stock register. The broker first informs us how many of their clients are beneficial owners and we provide them with the number of sets of proxy materials and proxy cards for the broker to then forward those proxy materials to shareholders to obtain voting instructions. For this reason, if your shares are held by your broker, you should follow your broker’s instructions included on that form when you receive the proxy materials from your broker.

If you do not give your voting instructions to your broker, your broker may not be able to vote your shares. Under applicable rules of self-regulatory organizations governing brokers, your broker, bank, custodian or other nominee will only be able to vote your shares with respect to so-called items that are considered “discretionary.” Discretionary items are proposals considered routine under the rules of the New York Stock Exchange, so in such situations your broker may vote these shares even in the absence of your voting instructions. For the 2022 Annual Meeting, the only discretionary item is Proposal No. 2, the ratification of the selection of our independent registered public accounting firm.

Election of Directors

For purposes of the election of directors (Proposal No. 1), the eleven director nominees who receive the highest number of votes cast “for” the election of those directors will be elected. However, the Board has adopted a policy requiring that, in advance of and as a condition to being approved as a candidate for election, each candidate must have agreed that if he or she receives a “withhold” vote of greater than 50% of all the votes cast or present at the meeting, the Board will consider that a majority vote “against” that person. Accordingly, he or she will be deemed to have automatically resigned. Under that policy, should this occur, the Board, in the exercise of its discretion, has the ability to override the resignation, but only if, upon a consideration of all pertinent factors, the Board makes an affirmative determination that accepting such resignation would not be in the best interest of the Company and its shareholders.

Other Proposals

For all proposals, other than Proposal No. 1 (the election of directors), the affirmative vote of a majority of the shares represented, in person or by proxy, and entitled to vote on the item will be required for approval. On such matters, you may vote “for,” “against” or “abstain.” A proxy marked “abstain” with respect to an item will not be voted, although it will be counted for purposes of determining whether there is a quorum. Accordingly, an abstention will have the same effect as a negative vote.

TABLE OF CONTENTS

Director Independence

The Board annually makes both an affirmative objective and subjective determination that all independence standards have been and continue to be met by the designated independent directors and members of each of our three standing committees, including compliance with the additional heightened independence standards prescribed by SEC and Nasdaq Listing Rules for audit committee and compensation committee members. To be found to be objectively independent, a director must be not be an officer or an employee of Steel Dynamics, Inc. or any of its subsidiaries. They must not have any relationship with Steel Dynamics, Inc. or any of its subsidiaries, or with management (either directly or as a partner, shareholder or officer of an entity that has such a relationship) which, in the Board’s opinion, would interfere with the exercise of independent judgment in carrying out the responsibilities as a director.

The Board made its independence determination with respect to each director for calendar year 2021 and for each director nominee for election to the Board of Directors at the 2022 Annual Meeting. The Board has similarly made an additional affirmative determination of independence with respect to each member of the Audit Committee and the Compensation Committee, under the special audit committee and compensation committee independence criteria set forth under applicable SEC rules and Nasdaq Listing Rules.

The Board determined that during 2021 nine of the twelve members of our Board of Directors met all independence requirements, at all times constituting 75% of our twelve-member Board. The independent members were Sheree L. Bargabos, Frank D. Byrne, M.D., Kenneth W. Cornew, Traci M. Dolan, James C. Marcuccilli, Gabriel L. Shaheen, Bradley S. Seaman, Luis M. Sierra and Steven A. Sonnenberg. Frank D. Byrne, M.D. has elected not to be included as a director nominee for Steel Dynamics at the 2022 Annual Meeting. The Board has determined that, if re-elected at the 2022 Annual Meeting, the same eight directors would continue to meet all independence criteria. In addition, the Board determined that all members of each of the three standing committees have been and will continue to meet all independence requirements.

TABLE OF CONTENTS

Board Leadership Structure
and Composition

We believe our board and governance framework provides for a sound and strong corporate governance environment. The Board has the flexibility to decide when the positions of Chair of the Board and CEO should be combined or separated, as well as whether an executive or an independent director should be Board Chair. If the Chair of the Board is not an independent director, the Board will designate one of its independent directors to serve as a lead independent director (as we have since 2011). This allows the Board to choose the leadership structure that it believes will best serve the interest of our shareholders at any particular time.

Chair of the Board

During 2021, Mr. Mark D. Millett served as our Chief Executive Officer and non-independent Board Chair. Mr. Millett is a founder of our Company and was appointed as our Board Chair at our 2021 Annual Meeting. As Board Chair, he presided as such at the Company’s Board meetings. The Company’s Board Chair serves at the pleasure of the Board and is appointed annually by the Board following the Annual Meeting.

Lead Independent Director

If the Chair of the Board is not an independent director, the Board will designate one of its independent directors to serve as a lead independent director, and this individual will be appointed annually following the Annual Meeting. As such, the Company’s Board operated with a Lead Independent Director in 2021. James C. Marcuccilli has served as our Lead Independent Director since 2011.

The Lead Independent Director: presides at Board meetings at which the Board Chair is not present; presides at Board executive sessions of the independent directors; serves as a liaison between senior leadership and the Board as well as between the Chair and the independent directors; assists the Board committee chairs in preparing agendas for the respective committee meetings; has the authority to call meetings of the independent directors, and performs other functions and responsibilities requested by the Board.

The Board considers that the Lead Independent Director’s active involvement in the foregoing functions and activities ensures the Board maintains independent oversight.

Independent Directors

Eight of eleven, or 73%, of our Board nominees are considered independent. These members meet in executive session at least quarterly. In addition, all of our committees are comprised of 100% independent members, and also meet regularly in executive sessions.

Committee Chairs

All committee chairs are independent and provide leadership for their respective committees. They provide an important resource for communications between the Board and the company’s senior leadership.

Board Committees

The Board of Directors has three standing committees, each consisting entirely of independent directors: an Audit Committee, Compensation Committee, and Corporate Governance and Nominating Committee.

The Board, together with senior leadership, regularly reviews the applicable provisions of the Sarbanes Oxley Act of 2002, the Dodd-Frank Act and the implementing rules thereunder, the rules and pronouncements of the SEC, pertinent provisions of the Internal Revenue Code of 1986 (the “Code”), and the Listing Rules of the Nasdaq Stock Market regarding corporate governance policies, processes, and listing standards, including applicable audit and compensation committee independence standards. In conformity with such requirements, the committees of the Board operate under written charters. All three committees, at least annually, review and, as necessary, revise their charters to take into account updated charter, legislative, regulatory, and listing standards requirements, as well as other governance best practices.

The following describes the operations and key responsibilities for each Board committee:

Board and Committee’s Role
in Risk Oversight

The Board of Directors has overall responsibility for risk oversight and focuses on the most significant risks facing the Company. The Board discharges its risk oversight responsibilities, in part, through delegation to its senior leadership team and, as applicable, to various of its committees, facilitated through both a top-down and bottom-up communication structure. In this regard, the Board believes that evaluating the executive team’s management of the various risks confronting the Company is one of its most important areas of oversight. In carrying out this critical responsibility, the Board with senior leadership’s assistance, regularly reviews the Company’s significant macroeconomic and business-specific risks, including but not limited to, health and safety, talent development, human resources, diversity and inclusion, financial, operational, information and cybersecurity, business continuity, legal, environmental, trade, technological and regulatory exposures.

While the Board and its committees oversee risk management strategy, leadership is responsible for implementing and supervising day-to-day execution and reporting to the Board and its committees on such matters. In this regard, the Board reviews and challenges the steps leadership has taken to actively assess, manage, monitor, and mitigate areas of exposure. Outlined below are the key areas of responsibility for each of the committees and how the Board and senior leadership supports each other in this critical function.

The Audit Committee reviews the Company’s risk management processes, systems and controls which senior leadership has established. Specifically, among other topics, the Audit Committee is responsible for reviewing the risks related to financial reporting and disclosure processes, as well as, capital structure, cybersecurity and information technology, liquidity sufficiency, financial regulatory compliance and market trends. The Audit Committee regularly discusses with senior leadership the Company’s significant financial risk exposures to ensure adequate mitigation is in place.

The Corporate Governance and Nominating Committee reviews legal and regulatory compliance risks as they relate to, among other things, corporate governance practices and processes. In that review are the risks related to environmental, climate and social matters that may arise, including the sustainability impact our operations have on our communities and the environment and the diversity of our teams. The Corporate Governance and Nominating Committee is responsible for the oversight of the Company’s sustainability performance. The Committee receives periodic reports on initiatives the company is pursuing related to climate change mitigation. The Committee was instrumental in providing feedback and guidance as the Company set environmental goals and pursued initiatives throughout the year. The Committee and senior leadership provide related information to the full Board based on these discussions, and how these initiatives will impact the Company’s strategic direction.

The Compensation Committee reviews our executive compensation programs to ensure they are using performance-based metrics that are aligned with Board and stakeholder strategy, and that they do not encourage unnecessary or excessive risk-taking. As described in further detail in our Compensation Discussion and Analysis, the Compensation Committee is evaluating a number of environmental, social and safety metrics for potential inclusion in our executive’s compensation to further align with stakeholder’s interests. As part of its review, the Compensation Committee utilizes its independent compensation consultant, Compensia, in its determination. During 2021, the Compensation Committee determined that our compensation programs do not encourage unnecessary or excessive risk-taking.

Steel Dynamics, Inc. | 2022 Proxy Statement 25

TABLE OF CONTENTS

Executive officers’ base salaries are fixed in amount and thus do not encourage risk-taking. Annual cash incentives are formulaic and tied to specific Company financial performance metrics. The majority of compensation provided to the executive officers is in the form of time-based and performance-based equity awards that vest or are earned over a number of years and help further align executive officers’ interests with those of our investors. Accordingly, the Compensation Committee believes that these awards do not encourage unnecessary or excessive risk-taking because the ultimate value of the awards is tied to the Company’s performance over several years, and awards are subject to regular vesting schedules to help ensure that a significant component of executive compensation is tied to long-term value creation.

The Compensation Committee has also reviewed the Company’s compensation programs for team members in general and has concluded that these programs also do not create risks that are reasonably likely to have an adverse effect on the Company. The Compensation Committee believes that the Company’s compensation programs provide an effective and appropriate mix of incentives to help ensure performance is focused on long-term value creation and does not encourage short-term risk taking at the expense of long-term results.

Director Nomination Process

The Corporate Governance and Nominating Committee regularly reviews the Company’s Board composition to continually update incumbent director skills, contributions and experiences, and for the purpose of identifying potential candidates for board membership in the event of possible retirements, unanticipated vacancies or board expansion. This process first identifies skills that are needed to support the Company and its near and long-term strategies, while also considering the factors listed below, and then identifies potential nominees to fill the need.

The Committee seeks proposed nominees with a reputation for the highest ethical and moral standards and integrity. The Committee reviews background information on each proposed nominee, including the proposed nominee’s accomplishments, experience, and skills. The Committee pursues nominees with skills including independent judgment, a proper understanding of the role of a director in governance, and financial literacy. A commitment to represent the long-term interests of the Company and our investors, as well as a commitment to prepare for, attend and actively participate in Board and committee meetings as well as a willingness to devote the necessary time and attention to the Company’s business and the needs of the Board and its committees is essential.

Among other things the Committee takes into account such factors as particular industry and general business knowledge, operating experience, demonstrated ethical business conduct, familiarity with or experience regarding business matters, exposure to public company governance matters, considerations such as safety, logistics, legal/governmental/environmental regulation experience, information technology, and risk assessment, as part of the director candidate qualification process.

Proposed nominees may be referred or recommended to the Committee from many different sources, including but not limited to members of the Committee, by other directors, by outside persons or advisors, by a shareholder in accordance with the procedures described below, or under the direction of the Committee and for its consideration and approval, by an outside independent professional search firm .

TABLE OF CONTENTS

Board Diversity

The Corporate Governance and Nominating Committee recognizes that a diverse set of skills and backgrounds is essential to proper functioning of our Board and that the judgments and perspectives offered by a diverse board of directors improves the quality of decision-making and enhances board performance. The Committee seeks persons within a broad range of business and personal experiences and backgrounds, considers a multitude of factors including, but not limited to, gender, race, ethnicity, country of origin and age. During 2021, the Corporate Governance and Nominating Committee nominated Mr. Sierra who brings a strong background in industrial and international operations, commercial and organizational strategy, and financial acumen to our Board. Mr. Sierra also has worked

extensively outside of the United States and is bilingual, speaking Spanish.

Currently two of our Board members self-identified as female and two of our Board members self-identified as ethnically diverse (Middle Eastern and Hispanic). The Committee believes it is important to create a Board with a diversity of experience, expertise, gender, race and ethnicity — therefore, the Committee commits to include in each search, candidates who reflect diverse backgrounds, including diversity of gender, race, and ethnicity.

The Corporate Governance and Nominating Committee believes the Board has met the diversity objectives of Nasdaq Listing Rule 5605(f)(2)(A).

Annual Director Evaluations

Members of the Corporate Governance and Nominating Committee also evaluate the continued candidacy of incumbent Board members based on the same criteria applicable to new candidates, taking into consideration such factors as age, board tenure, membership on other public company boards of directors, diversity, ability to provide subject matter expertise and insight into our long-term strategic direction and the extent to which through his or her prior participation and performance he or she has met the applicable criteria for continued Board membership and has developed a valuable in-depth knowledge of the Company and its business.

Director Meetings and the Annual Meeting

The Board held six regularly scheduled and special meetings during 2021. All directors attended at least 75% of those meetings, as well as the meetings of each of the committees on which they served. As the Board, the Company’s independent directors met in executive session four times during 2021, without the Company’s leadership present.

We encourage all members of the Board to attend our Annual Meeting. At the 2021 Annual Meeting all directors were in attendance with most attending virtually due to restrictions related to COVID-19.

Leadership Succession Planning

The Board also engages in regular discussions with the Chief Executive Officer regarding leadership succession planning at all senior levels, including the Chief Executive Officer, and to the identification, development, and promotion of critical talent to address both planned and unplanned leadership transitions. The Chief Executive Officer reports at least semi-annually on succession and leadership development planning. The Company also encourages talent development and succession planning at all levels throughout the organization through broad-based ongoing education and development opportunities. The Company has developed internal programs for company-wide development opportunities specifically designed to teach leadership skills and how they are interpreted within the Company’s culture.

Statement of Policy for the Review, Approval or Ratification of Transactions with Related Persons

Under our policy, once a person has been identified as a “related person,” and if there is a proposed transaction of $120,000 or more involving the related person and the Company or any of its subsidiaries, the transaction must be considered, approved or ratified by the Audit Committee. For purposes of our Policy, a “related person” is a person who is (or at any time since the beginning of our last fiscal year was) a director, director nominee, executive officer, 5% shareholder, immediate family member of any of the foregoing, an entity which is owned or controlled by any of such persons, or any other person which our Audit Committee or Board has so identified.

Covered transactions will normally be approved in advance by the Audit Committee, unless, upon certification by our Chief Executive Officer or Chief Financial Officer that a determination cannot be practicably made prior to the next Audit Committee meeting, the Chair of the Audit Committee is able to review and approve the proposed related person transaction, subject, however, to the prompt reporting of the transaction to the full Audit Committee.

The Audit Committee determined during 2021 there were no material related party transactions with Named Executive Officers or directors.

Any shareholder satisfying the requirements of Exchange Act Rule 14a-8 and wishing to submit a proposal for inclusion in our proxy statement for our 2023 Annual Meeting must submit the proposal in writing to the attention of our Chief Financial Officer, Theresa E. Wagler, at 7575 West Jefferson Blvd., Fort Wayne, Indiana 46804, no later than November 29, 2022.

These include requirements regarding the minimum market value of the shares you hold, the length of time you have held those shares, and the applicable deadline for submitting the proposal.

In addition, if a shareholder does not submit a timely or otherwise qualifying proposal for inclusion in 2023’s Annual Meeting Proxy Statement but may still wish to make a business proposal at that meeting for consideration at the meeting, including a nomination for director, will be required to have delivered written notice to our Chief Financial Officer no later than November 29, 2022 containing biographical and other required information pertinent to the subject matter of the proposal. There were no such proposals submitted for consideration at this year’s Annual Meeting.

Proposal #1

Election
of Directors

Our shareholders will be asked to elect eleven directors at the 2022 Annual Meeting.

Ten of the persons listed below are incumbent members of our Board and, except for Luis M. Sierra, were elected at the 2021 Annual Meeting. As a result of its ongoing director performance review by the Corporate Governance and Nominating Committee (see “Director Nomination Process”) each incumbent Board member’s service and performance as a director during 2021 was evaluated by the Corporate Governance and Nominating Committee and was determined to have met all expectations for continued Board membership. In addition, Mr. Sierra’s qualifications were reviewed and found to fit nicely with the Board member qualifications criteria established by the Corporate Governance and Nominating Committee. The Committee determined that it would be in the best interest of the Company that each director, whom have expressed his or her willingness to continue to serve, should continue to do so. Accordingly, eleven director candidates, having indicated their willingness to stand for election for an additional one-year term, were recommended for nomination by the Committee and are hereby nominated for election to the Board.

Each director, if elected, will serve until our 2023 Annual Meeting, or until a qualified successor director has been elected. All but Messrs. Millett, Busse and Teets are, and will continue to be, independent directors. In the event that any nominee at the time of the election is unable to serve or is otherwise unavailable for election, the Board, upon recommendation of the Corporate

Governance and Nominating Committee, may select a substitute nominee. In that event, the persons named in the enclosed proxy intend to vote the proxy for the person so selected. We do not anticipate that any nominee will be unable to serve.

In addition, the Board has also reviewed all transactions during 2021 between Steel Dynamics, Inc. or any of its subsidiaries or affiliates, and companies or entities in which a director or a family member or affiliate might have owned any interest, for the purpose of ensuring that such transactions, if any, were approved in accordance with our “Statement of Policy For the Review, Approval or Ratification of Transactions With Related Persons”, and, further, for the purpose of determining whether any of such transactions impacted the independence of any director. The Board has affirmatively determined that none of the independent directors is an officer or employee of the Company, or any of our subsidiaries, and none of such persons have any relationships which, in the opinion of our Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Ownership of a significant amount of our stock, by itself, does not constitute a material relationship or impact that person’s independence.

The board of directors recommends a vote for each of the following nominees

TABLE OF CONTENTS

Cash Compensation

For 2021, the standard cash compensation retainer for the non-employee members of the Board, as well as any additional cash received for respective committee chairs, were as follows:

	Annual Retainers			Committee Chair
Non-employee Director		$	125,000
Lead Independent Director			165,000
Audit Committee					$	25,000
Compensation Committee						20,000
Corporate Governance and Nominating Committee						20,000

Non-employee members of the Board may elect to defer up to 100% of their annual cash retainer relating to their Board service, in increments of 10%, in the form of additional deferred stock units (“DSU”), as further described below under “Equity Compensation.” The actual number of DSUs is determined by dividing the dollar amount of the board service cash retainer amount that is the subject of the election by the closing price of the Company’s common stock at the close of business on the last business day preceding the date of the elected cash retainer payment. This deferral election must be made prior to December 31st of the calendar year preceding the year for which the deferral election is made and to elect, in advance, the desired deferral period, specifically, for a period of either one year, or the earlier to occur of five years or one year following his or her retirement from the Board.

Equity Compensation

Non-employee members of the Board also receive an annual equity award, in the form of DSUs. In 2021, these director DSU awards each had a grant date fair value of $144,000. The grant is made annually, as of June 1, and the number of DSUs is determined by a formula, set forth in the Amended and Restated Steel Dynamics, Inc.

2015 Equity Incentive Plan (“2015 Plan”), under which the equity portion of the annual Board service retainer is divided by the closing price of the Company’s common stock at the close of business on the last business day preceding June 1, to arrive at the specified number of DSUs. Each DSU is a book-entry award expressed in common stock equivalent units and ultimately settled at the end of the deferral period in a like number of shares of the Company’s common stock.

Equity Ownership Policy for Directors

We maintain an equity ownership policy for the non-employee members of the Board. Under this policy, each non-employee member of the Board is required to own and hold shares of the Company’s common stock equal to at least five times his or her annual cash retainer, currently $125,000, for an aggregate of $625,000. We review compliance with this policy annually and require each non-employee member of the Board to meet his or her respective equity ownership requirement within five years of joining the Board. We believe that each of the existing non-employee members of the Board either has satisfied, or will satisfy, this requirement on a timely basis. Our Board contains two of our top 15 shareholders and collectively our Board members own 4.8% of our outstanding common stock.

Proposal #2

Ratification of
the Appointment
of Independent
Registered Public
Accounting Firm
as Auditors

In accordance with the provisions of the Sarbanes Oxley Act of 2002, the Audit Committee has appointed Ernst & Young LLP (Ernst & Young) as our independent registered public accounting firm, to conduct our annual audit for the year 2022. Although not legally required, but in accordance with established policy, we are submitting this appointment to shareholders for ratification. In the event the appointment is not ratified, we anticipate that no change in auditors would be made for the current year because of the difficulty and expense of making any change mid-year. However, any such vote would be considered in connection with our deliberation of the appointment of an independent registered public accounting firm for 2023.

Ernst & Young conducted our annual audit for 2021, and representatives of Ernst & Young will be present and will be available at the meeting to respond to questions from shareholders, and, if the representatives desire, will have an opportunity to make a statement.

The Board of Directors recommends a vote FOR the approval of the appointment of Ernst & Young LLP as our independent registered public accounting firm for 2022.

Audit and Non-Audit Fees

The following table presents fees for services rendered by Ernst & Young, as the Company’s independent registered public accounting firm, for the years ended December 31, 2020 and 2021.

with the independent registered public accounting firm the assessment of the critical audit matter.

Oversight and Assessment of the Independent Registered Public Accounting Firm

The Audit Committee selects and appoints our independent registered public accounting firm, reviews the performance of the independent registered public accounting firm in the annual audit and in assignments unrelated to the audit, and reviews and approves the fees. Ernst & Young has been Steel Dynamics’ independent registered public accounting firm since 1999 and in addition to its ongoing annual performance evaluation, the Audit Committee also considers the impact, if any, of auditor tenure when assessing whether to retain Ernst & Young. The Audit Committee approved the selection and engaged the services of Ernst & Young as our independent auditing firm for the Company’s fiscal year ended December 31, 2021, after employing its annual quality and review process described below.

In 2021, the Audit Committee, with assistance from management, conducted a formal performance appraisal of Ernst & Young, soliciting the opinions of the Audit Committee, internal audit, executive management and other relevant Company employees. In determining whether to appoint Ernst & Young as Steel Dynamics’ independent registered public accounting firm for 2022, the Audit Committee took into consideration a number of factors, including the frankness and quality of the Audit Committee’s ongoing discussions with our auditor, the auditor’s independence, and the assessment of the professional qualifications and past performance of both Ernst & Young as a whole and the Lead Audit Partner. The results assessed Ernst & Young’s performance to have met all expectations. In that regard, the Audit Committee recommends engaging Ernst & Young as our independent auditing firm for the Company’s fiscal year ending December 31, 2022.

Required Disclosures and Discussions

In connection with the December 31, 2021 audited consolidated financial statements, the Audit Committee:

■

Met with Ernst & Young eight times with management present and four times without management present.

■

Discussed with Ernst & Young the matters required to be discussed in Auditing Standard No. 16 (Communication with Audit Committees), issued by the Public Company Accounting Oversight Board (United States) (“PCAOB”), now codified as AS No. 1301, as well as Auditing Standard No. 18 (Related Parties).

■

Received and reviewed the written disclosures and the letter from Ernst & Young required by PCAOB Rule 3526 (Communication with Audit Committees Concerning Independence) and has discussed with the auditors their independence.

■

Reviewed and discussed with management and with Ernst & Young management’s report on Steel Dynamics’ internal control over financial reporting and Ernst & Young’s report on the effectiveness of Steel Dynamics’ internal control over financial reporting and the assessment of the critical audit matter identified by Ernst & Young.

■

Discussed whether the provision of services by Ernst & Young and the fees paid to them for services not related to the audit of the financial statements referred to above, is compatible with maintaining Ernst & Young’s independence.

Recommendation to Include the Financial Statements in the Annual Report

Based upon the Audit Committee’s discussions with management and our independent registered public accounting firm, and the Audit Committee’s review of the audited financial statements, the representations of management and the report of our independent registered public accounting firm to the Audit Committee, the Audit Committee recommended to the Board of Directors, and the Board of Directors approved, the inclusion of the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Executive Summary

2021 Business Overview

Our commitment is to the health, safety and well-being of our teams, families, and communities and to meet the needs of our customers. Our culture and our business model positively differentiate our company and performance. We are in a place of strength. We are competitively positioned and focused to deliver long-term value creation for all of our stakeholders.

During 2021, we achieved record financial and operating results at each of our three primary operating platforms. We continue to be differentiated by maintaining our focus on customer supply-chain solutions and value-added products with over 70% of our steel and steel fabrication shipments considered value-added. The graphic below highlights our key achievements in 2021:

[MISSING IMAGE: tm223421d1_fc-performpn.jpg]

Steel Dynamics, Inc. | 2022 Proxy Statement 45

TABLE OF CONTENTS

As demonstrated, we believe that our business model and unique operating culture generate strong cash flow through all market cycles — based on the low, highly-variable cost structure of our operations, our highly diversified, value-added product offerings and customer supply-chain solutions. The strength of our through-cycle cash generation coupled with a strong capital structure foundation provides the opportunity for continued organic and transactional growth while also providing strong shareholder distributions. We are squarely focused on the continuation of sustainable, optimized value creation.

2021 Shareholder Engagement and Say-on-Pay

At our 2021 Annual Meeting, we conducted a non-binding advisory vote on the compensation of our NEOs, commonly referred to as a “say-on-pay” vote. Our shareholders approved our NEOs’ compensation with 93% of the votes cast on the proposal voting in favor of our executive compensation program.

Based on strong say-on-pay support and in combination with feedback from our shareholder engagement efforts, the Compensation Committee has retained the program’s emphasis on both short-term annual performance-based incentives that reward our NEOs when we meet certain profitability hurdles and long-term performance-based incentive compensation opportunities that promote the creation of sustainable long-term value for our shareholders.

Consistent with the recommendation of the Board and the preference of our shareholders, as expressed at the 2017 Annual Meeting, to hold advisory say-on-pay votes on the compensation of our NEOs on an annual basis, the Board has decided to continue this policy. Accordingly, following this Annual Meeting (to which this Proxy Statement relates), which will include this year’s (2022) annual advisory say-on-pay vote, the next advisory say-on-pay vote will take place in 2023. The next say-on-frequency vote will take place in 2023.

Strong Compensation Best Practices

We are committed to sound compensation practices that encourage a long-term focus on stakeholder value creation and to sustainability of our resources, as highlighted by the following items:


	■			Highly levered company-wide performance-based compensation
	■			Strong shareholder say-on-pay support with 93% voting in favor during 2021
	■			Robust stock ownership requirements for all executive officers
	■			Clawback policy regarding executive compensation
	■			“Double-trigger” change-in-control payments and benefits
	■			No excise tax gross ups
	■			Prohibit hedging and a severe limitation of pledging of Company stock
	■			Independent compensation consultant retained by the Compensation Committee

Focus on ESG Metrics in 2022

2021 Executive Compensation Decisions

As in prior years, the Compensation Committee made no adjustments to the pre-established metrics or performance measures of any award for 2021.

What Drives our Program

Compensation Philosophy and Objectives

Our executive compensation program reflects a continuation of the team-oriented entrepreneurial culture upon which the Company was founded and that has contributed to our success. While the type of executive we seek to attract and retain might have the opportunity to work elsewhere at a higher guaranteed base wage, nonetheless, we believe that he or she will want to work for us because of the opportunity to earn a higher multiple of that guaranteed base wage in years in which his or her efforts have contributed to a substantially more profitable year for the Company, our people and our shareholders. Fundamental to this philosophy is the recognition of the central role that teamwork, collaboration, and transparency play in the achievement of this kind of consistent superior financial and operational performance, under all market conditions, both at the executive and operating levels. This philosophy is, reflected at every level of the Company, from our colleagues on the plant floor to corporate and divisional senior leaders.

Both our annual and long-term incentive compensation award opportunities have a common and intentional “pay-for-performance” design. Each program rewards one or more elements important to the interests of the Company, our teams, and our shareholders. Our executive compensation program contains a significant majority of compensation “at risk” and aligns with shareholder interests with clear, objective return metrics that over the long-term drive value creation.

When compared to our steel competitors (as we do in our LTIP), we continue to achieve best-in-class operating and financial performance. Our CEO’s target total direct compensation remains below the 25 th percentile of the chief executive officers of the companies included in our compensation peer group.

Principal Elements of Pay

Our philosophy drives the following compensation design principles:

■

base salary is fixed, payable in cash, and generally set at or below the competitive market, yet, when combined with the potential from our highly-levered annual incentive compensation plan, aspires to be sufficiently competitive to attract and retain the type of entrepreneurial executives we seek;

■

annual incentive compensation should be awarded only after earnings first exceed certain minimum threshold levels established by the Compensation Committee and designed to initially provide a minimum return to shareholders, with annual incentive compensation awards dependent upon additional earnings beyond such minimums, capped, however, at pre-established multiples of base salary;

■

long-term incentive compensation should be predominantly performance-based, including awards linked to shareholder returns and with awards measured by how our executives have performed relative to our steel sector competitors over a multi-year period, based on pre-established key financial and operational measures;

■

total direct compensation across all market conditions should be market competitive when Company performance so merits, but below market norms when that performance lags; and

■

rewards for exemplary individual effort and performance over time should generally be expressed through annual increases in the level of base salary.

Our executive compensation program appropriately balances the use of both absolute and relative performance measures for incentive compensation.

The Decision-Making Process (Administration)

Role of the Compensation Committee

The Compensation Committee has responsibility for the development, implementation, monitoring, and oversight of our executive compensation program, as well as responsibility for ensuring that our compensation plans and programs remain consistent with our compensation philosophy. The Compensation Committee annually evaluates and establishes the compensation of our Chief Executive Officer and, with the input of our Chief Executive Officer, the compensation of our other executive officers, including our other NEOs; evaluates and establishes the compensation for the non-employee members of the Board; and reviews and approves all cash and equity-based incentive plans and awards under such plans.

The Compensation Committee meets throughout the year to perform its duties and responsibilities. During 2021, the Compensation Committee held four meetings. From time to time, the Compensation Committee may invite our Chief Executive Officer, our Board Chair, or other executive officers to attend and participate in portions of its meetings, but only Compensation Committee members are present during compensation-related decision-making.

Role of Our Chief Executive Officer

Our Chief Executive Officer supports the work of the Compensation Committee by providing necessary background information and updates on the operations of the Company and the performance of each of our executive officers. Our Chief Executive Officer

recommends adjustments to the base salaries, target annual incentive compensation award opportunities, and long-term incentive awards of our executive officers, including our NEOs who report directly to him. He also provides the Compensation Committee with an annual performance evaluation of each executive officer.

The Compensation Committee receives a
recommendation from our Chief Executive Officer as to any proposed adjustment to his own compensation, as well as a self-assessment of his performance for the year under review. However, the Compensation Committee evaluates the performance of our Chief Executive Officer based on the full Board assessment and input, and exercises its judgment as to whether, and to what extent, to adjust his compensation levels and whether to adjust the compensation levels of any of our executive officers.

Role of Compensation Consultant

The Compensation Committee has authority to engage the services of compensation consultants or other advisors, at the Company’s expense, as it deems necessary or appropriate in the discharge of its duties and responsibilities. During 2021, the Compensation Committee engaged the services of Compensia, Inc., a national compensation consulting firm, to provide ongoing executive and director compensation advisory services.

Compensia reports directly to the Compensation Committee. The Compensation Committee may replace

TABLE OF CONTENTS

its compensation consultant or hire additional advisors at any time. Representatives of Compensia attend meetings of the Committee and communicate with the Committee Chair and with management as circumstances warrant. However, all decisions regarding the compensation of our executive officers are made by the Compensation Committee. The Compensation Committee has assessed the independence of Compensia taking into account, among other things, the enhanced independence standards and factors set forth in Exchange Act Rule 10C-1 and the applicable Nasdaq Listing Rules, and concluded that Compensia meets all applicable independence criteria, and that there are no conflicts of interest with respect to the work that Compensia performs for the Compensation Committee.

During 2021, the Company also engaged Pearl Meyer, a national compensation consulting firm, to assist in determining the appropriateness of our compensation peer group, analyze the compensation for our NEOs, and evaluate the compensation of our NEOs against our compensation peer group and the broader market. Compensia reviews and provides input on Pearl Meyer’s work before it is delivered to the Compensation Committee.

Use of Competitive Data

To monitor the competitiveness of our executive officers’ compensation, the Compensation Committee uses a compensation peer group which reflects the pay of executives in comparable positions at similarly-sized companies. This compensation peer group is composed of a cross-section of direct steel competitors as well as companies in related industrial or basic materials sectors. The Compensation Committee reviews the appropriateness of the compensation peer group annually. For our 2021 compensation decisions, the Compensation Committee made no changes to the compensation peer group.

The Compensation Committee used the following compensation peer group as a reference during its compensation deliberations in 2021:

■

AGCO Corporation

■

AK Steel Holding Corporation

■

Commercial Metals Company

■

Dover Corporation

■

Flowserve Corporation

■

Illinois Tool Works Inc.

■

Masco Corporation

■

Navistar International Corporation

■

Newmont Mining Corporation

■

Nucor Corporation

■

Oshkosh Corporation

■

PACCAR Inc

■

Parker-Hannifan Corporation

■

Reliance Steel & Aluminum Co.

■

United States Steel Corporation

We do not believe that it is appropriate to make compensation decisions based strictly upon any type of benchmarking to a peer or other representative group of companies. However, the Compensation Committee does believe that information regarding the compensation practices at other companies is useful in at least two respects. First, the Compensation Committee recognizes that our compensation policies and practices must be competitive in the marketplace to attract and retain executive talent. Second, this information is useful in assessing the reasonableness and appropriateness of individual executive compensation components and of our overall executive compensation program. Peer group information is only one of a number of factors that the Compensation Committee considers in making its decisions with respect to the compensation of our executive officers.

Steel Dynamics, Inc. | 2022 Proxy Statement 49

TABLE OF CONTENTS

2021 Executive Compensation Program in Detail

The following describes each component of our executive compensation program and how compensation amounts were determined for our NEOs for 2021.

Base Salary

We use base salaries to provide an essential level of compensation we believe is necessary to recruit and retain the type of entrepreneurial executives we seek to attract, and who are willing to accept such base-level compensation in challenging market conditions, even in situations in which their individual and collective efforts and performance has been outstanding.

The Compensation Committee, in the course of its annual performance review process, considers each executive officer’s position, responsibilities and duties, as well as his or her experience, qualifications, and performance, for purposes of determining whether to adjust his or her base salary. Base salary adjustments are also influenced by the Compensation Committee’s analyses of the base salary levels for executives in comparable positions in the competitive marketplace.

In February 2021, the Compensation Committee reviewed the base salaries of our NEOs, taking into consideration the factors described above, in addition to the recommendation of our Chief Executive Officer. Exercising its judgment and discretion, the Compensation Committee made the following changes to our NEO’s base salaries:

	2020			2021			% Change
Mr. Millett		$	1,390,000		$	1,390,000		0	%
Ms. Wagler			710,000			710,000		0	%
Mr. Rinn			590,000			590,000		0	%
Mr. Pushis			555,000			590,000		6	%
Mr. Schneider			555,000			590,000		6	%

Annual Incentive Compensation Plan

Consistent with our compensation philosophy, the majority of the annual compensation opportunity for our NEOs is provided through objectively-determined Company and divisional performance-based incentive compensation awards under the Annual Plan. The Annual Plan has a short-term focus, consistent with our objective of providing annualized incentive compensation linked to Company and/or business unit profits above a pre-established minimum threshold.

In 2021, our broad group of executive officers, including but not limited to our NEOs (a group of 29 individuals) were eligible to participate in the Annual Plan. Each NEO, based on his or her role and responsibilities, was eligible to participate as one of the two broad categories of officers identified in the Annual Plan — “Corporate Executive Officer” or “Divisional Executive Officer.” This determines the amount of the maximum award that he or she is eligible to receive, and the determining factors used to calculate that award. Annual incentive compensation awards are determined on February 1 of the year following the year for which the incentive compensation is earned, based upon the Company’s audited results of operations.

The award is first paid in cash with the remainder (up to 100% of base salary for each NEO) awarded in restricted stock. The number of shares of restricted stock issuable to an executive officer, if any is earned, is determined by dividing the dollar amount of the restricted stock component of the award by the closing market price of the Company’s common stock on the last business day prior to February 1. These restricted stock awards vest as to one-third of the shares of the Company’s common stock covered by the award at the time of issuance and as to the remaining two-thirds of the shares covered by the award in equal installments on the first and second anniversaries of the date of issuance.

TABLE OF CONTENTS

The following table highlights the target opportunities as well as the minimum and maximum bonus opportunities for each component of the Annual Plan expressed as a percentage of base salary:

	Target	Corporate Bonus Pool Component	Divisional ROA Bonus Pool Component
Mr. Millett	175%	0% to 350%	N/A
Ms. Wagler	175%	0% to 350%	N/A
Mr. Rinn	175%	0% to 175%	0% to 175%
Mr. Pushis	150%	0% to 120%	0% to 180%
Mr. Schneider	150%	0% to 120%	0% to 180%

Award Measures and Calculations

Corporate Bonus Pool Component

In the case of the Corporate Executive Officers and other corporate level pool participants, their annual incentive compensation award opportunities are based entirely on their participation in the “Bonus Pool” component of the Annual Plan. The size of the Bonus Pool is determined based on company-wide “Adjusted Net Income”, in excess of a pre-determined threshold return on “Average Stockholders Equity” multiplied by a fixed percentage. Both the threshold return and the fixed percentage are set by the Compensation Committee. Adjusted Net Income is defined as consolidated net income, before taxes and extraordinary items, including adjustments for occasional start-up expenses associated with significant capital expenditures or businesses, non-cash asset impairments, and charges associated with refinancing activities. Average Stockholders Equity, which was derived by taking the sum of “Total Steel Dynamics, Inc. Equity,” as determined by the Company’s balance sheet for the month ended December 31, 2020, and for each month during 2021, and then dividing that amount by 13 was $5.2 billion.

For 2021, the applicable pre-determined threshold return for shareholders was maintained at 10%, as was the fixed percentage of Adjusted Net Income available to the Bonus Pool at 5.5%. The Compensation Committee believes it is essential for the Company’s shareholders to benefit from a minimum return-on-equity (currently set at 10%) before any performance-based compensation begins to accrue through the Annual Plan.

The exclusion from the Bonus Pool of an amount of Average Stockholders Equity component is intended to preserve within the Company a deemed return on equity before any incentive compensation is paid, predicated on Company profits and, consequently, operates as a threshold level of performance that must be exceeded before the Bonus Pool (if any) is determined.

Divisional ROA Bonus Component

In the case of the Divisional Executive Officers and other operational level pool participants, their annual incentive compensation award opportunities are based both on a company-wide performance measure (as determined by the “Bonus Pool” component of the Annual Plan) and on a profitability-based performance measure based upon the profitability of the divisional or business unit under their management, against a calculated return on assets percentage amount referred to as the “Minimum ROA Target.”

Steel Dynamics, Inc. | 2022 Proxy Statement 51

TABLE OF CONTENTS

For 2021, the Compensation Committee retained the Minimum ROA Target, which varied by business unit (between 0% and 6%), below which no divisional or business unit profitability-based annual incentive compensation award will be paid. The Compensation Committee also retained a “Maximum ROA Target,” which also varied by business unit (between 20% and 30%), at which level a Divisional Executive Officer would be entitled to receive his or her maximum divisional or business unit annual incentive compensation award. The primary considerations included in determining the Minimum ROA Targets and Maximum ROA Targets were as follows: the amount of capital assets required to operate and maintain the particular division or business unit; the expected financial margin that a specific division or business unit has the opportunity to achieve (in both moderate and exceptional market environments); and the materiality of the contribution that a specific division or business unit may have on the consolidated financial results of the Company.

For 2021, the division or business unit’s performance was measured by calculating that unit’s “Divisional Return on Assets,” using the formula set forth in the Annual Plan, by dividing the sum of (i) the appropriate division’s pre-tax income for the year, (ii) the amount of certain corporate expenses allocated to that division, and (iii) the amount of incentive compensation award compensation expenses associated with the Annual Plan, by the “Average Divisional ROA Assets” or “Average Divisional Group ROA Assets.”

2021 Annual Incentive Award Earned

The company’s extraordinary results and record earnings resulted in the NEOs meeting the Compensation Committee’s pre-determined 2021 financial metrics for both the Bonus Pool and divisional portions of their annual incentive awards. The NEOs achieved their maximum 2021 annual incentive award opportunities.

The following table summarizes the key components of the 2021 annual incentive awards earned by our NEOs:

	Corporate Bonus Pool - Actual % of Base Salary	Divisional Results - Actual % of Base Salary	% of Actual Base Salary Paid in Cash	% of Actual Base Salary Paid in Restricted Stock
Mr. Millett	350%	N/A	250%	100%
Ms. Wagler	350%	N/A	250%	100%
Mr. Rinn	175%	175%	250%	100%
Mr. Pushis	120%	180%	200%	100%

TABLE OF CONTENTS

Long-Term Equity Incentive Compensation

The entirety of long-term incentive compensation is comprised of equity, which directly aligns the interests of our NEOs with those of our shareholders. The Compensation Committee considers a mix of equity types when granting long-term incentives with a significant weight on long-term incentive plan awards.

The Compensation Committee considers the award opportunities for executives in comparable positions in our compensation peer group when determining long-term equity incentive compensation awards. The unique performance criteria for each award type are explained in further detail below. The grant date fair values of each award are as follows:

	LTIP	SARs	RSUs	Total
Mr. Millett	$ 2,432,500	$ 1,000,012	$ 1,170,867	$ 4,603,379
Ms. Wagler	887,500	200,008	468,459	1,555,967
Mr. Rinn	737,500	200,008	237,764	1,175,272
Mr. Pushis	737,500	200,008	234,881	1,172,389
Mr. Schneider	737,500	200,008	234,881	1,172,389

Long-Term Incentive Plan

Consistent with our pay-for-performance compensation philosophy, the LTIP provides long-term incentive compensation opportunities to our NEOs based on our relative financial performance compared against our steel sector competitors. During 2021, each of our NEOs was eligible to participate in the LTIP. The Compensation Committee considers the award opportunities for executives in comparable positions in our compensation peer group when determining annual LTIP awards to grant.

2021 Award Measures and Calculations

For purposes of the 2021 LTIP awards (the “2021 Awards”), the Compensation Committee established four performance measures, to be weighted equally (25% each) to be used throughout the performance period. The Compensation Committee has selected these performance measures for determining the amount of the awards earned because they believe that they are also objective indicators of our ability to execute on our long-term strategic initiatives in a dynamic and volatile global economy and industry. Additionally, the Compensation Committee selected the steel sector competitors which consisted of Cleveland-Cliffs Inc., Commercial Metals Company, Nucor Corporation, TimkenSteel Corporation and United States Steel Corporation. These companies were selected because the Compensation Committee determined that they best represent the principal companies within our industry with which we compete for business.

Steel Dynamics, Inc. | 2022 Proxy Statement 53

TABLE OF CONTENTS

The performance measures selected for the 2021 Awards were as follows:

	Performance Measures			Calculation
	Revenue Growth			Total revenue in current performance period minus total revenue in previous performance period divided by total revenue in previous performance period
	Operating Margin			Total operating income for the performance period divided by total revenue for the performance period
	Cash Flow from Operations as a Percentage of Revenue			Total cash flow from operations for the performance period divided by total revenue for the performance period
	After-Tax Return on Invested Capital			Total net income for the performance period divided by total quarterly average equity and debt for the performance period

The amount of a NEO’s target and maximum awards are determined by the Compensation Committee based on a multiple of his or her annual base salary as of the first day of the performance period (for example, January 1). This value is then converted into a target and maximum number of shares of the Company’s common stock, using the closing market price at the close of business on the first day of the performance period. Generally, awards will be granted during February of each year.

In the case of the 2021 Awards, for each performance measure, the award payout with respect to that measure has a range from zero to 100% of the maximum number of shares awarded, subject to further review during the time allotted for determination for each subsequent award, based on the Company’s ranking for that measure as compared to the steel sector comparator group:

	If the ranking is			Then the payout is
	1st or 2nd			100%
	3rd			60%
	4th			40%
	5th or 6th			0%

The performance measures and comparator group were established by the Compensation Committee within the first 90 days of the three-year performance period. Any shares of the Company’s common stock earned pursuant to the 2021 Awards will vest at the time the amount of the award payout is determined (approximately mid-March of the year following the completion of the three-year performance period).

TABLE OF CONTENTS

The number of shares of the Company’s common stock earned with respect to the 2019 Awards that were eligible to be earned for the three-year performance period from 2019 to 2021 was determined in March 2022. As a result of the Company’s performance in each of the four areas of performance measures (equally weighted) relative to the performance of the steel sector competitors (Commercial Metals Company, Nucor Corporation, TimkenSteel Corporation and United States Steel Corporation), the award payout was calculated to be 90% of the maximum potential number of shares granted. This resulted in 139,656 shares of the Company’s common stock being earned by Mr. Millett, 50,247 shares earned by Ms. Wagler, 42,120 shares earned by Mr. Rinn, 38,794 shares earned by Mr. Pushis and 38,794 shares earned by Mr. Schneider.

SARs

During 2021, the Compensation Committee granted SAR awards to our NEOs further aligning their long-term incentive opportunity with the long-term interests of our shareholders. The Compensation Committee considers award opportunities for the executives in comparable positions in our compensation peer group when determining the size of the annual SARs awards to grant.

The SARs have a ten-year term and a three-year graduated vesting schedule, such that one-third of shares of the Company’s common stock subject to the awards will vest (become exercisable) 12 months following the date of grant, and, thereafter, 1/24 th of the remaining shares subject to the awards will vest monthly in equal installments, contingent upon each NEO’s continued employment with the Company on the applicable vesting date. The exercise price of the SARs was equal to 100% of the fair market value of the shares of the Company’s common stock using the closing market price of the Company’s common stock on the last business day prior to the grant date. When exercised, the Company will pay the recipient an amount at settlement only in cash, subject to mandatory tax withholdings, equal to the product of the appreciation value of the SAR multiplied by the number of exercised SARs.

Further information about these awards are set forth in the 2021 Summary Compensation Table and the 2021 Grants of Plan-Based Awards Table following this CD&A.

RSUs

The Company, since its initial public offering, has provided regular equity-based awards, currently in the form of an RSU award for shares of the Company’s common stock, at prescribed award levels, to all full-time, non-union, U.S. colleagues, including our NEOs. These RSU awards are granted on November 21 st of each year, using the closing market price of the Company’s common stock on the last business day prior to that date. Eligible colleagues are granted an annual RSU award for shares of the Company’s common stock, which are subject to a two-year time-based vesting requirement, which commences on the date of grant. In November 2021, pursuant to this company-wide program, the Compensation Committee granted RSUs to Mr. Millett with a grant date fair value of $87,029 and to our other NEOs with grant date fair values ranging from $50,541 to $69,610.

In February 2021, the Compensation Committee also granted RSUs to our NEOs with a longer vesting schedule, vesting 1/3 after two years, 1/3 after three years and 1/3 after four years to Mr. Millett with a grant date fair value of $1,083,838 and to our other NEOs with grant date fair values ranging from $168,154 to $401,131. Beginning in 2019, the Compensation Committee began granting awards to senior leadership with longer vesting schedules to provide a more meaningful and effective retention incentive, and further develop a competitive and balanced compensation package.

Further information about these awards are set forth in the 2021 Summary Compensation Table and the 2021 Grants of Plan-Based Awards Table following this CD&A.

Other Programs, Policies and Guidelines

Welfare, Health and Other Benefits; Perquisites and Other Personal Benefits

The welfare and health benefits received by our NEOs are provided on the same general terms as to all our full-time colleagues. In 2021, the Company paid the premiums associated with term life insurance for Mr. Millett with a benefit amount equal to $900,000. In 2021, no NEO received $10,000 or more in perquisites. Perquisites or other personal benefits are not a significant component of our executive compensation program.

TABLE OF CONTENTS

Profit-Sharing and Retirement Savings Plan

We have established a Profit Sharing and Retirement Savings Plan for eligible colleagues, including our NEOs, which is a “qualified plan” for federal income tax purposes. For 2021, under the plan, we allocated to eligible plan participants $360 million which was based on 8% of our consolidated pre-tax income, excluding noncontrolling interests and other items (the “profit-sharing pool”). The profit-sharing pool is used to fund the plan, which includes a separate cash profit sharing allocation that may be paid in March of the following year. For 2021, the amounts allocated to each of our NEOs, based on the profit-sharing pool and the cash profit sharing allocation was $130,051.

Additionally, we match 401(k) contributions with a minimum match of 10% and a maximum match of 50% based on a company-wide return on assets calculation. For 2021, the amounts for our NEOs based upon the Company’s average matching percentage during the year of 31% of his or her individual contributions, ranged from $5,068 to $6,229, including a matching contribution of $5,068 to our Chief Executive Officer, Mr. Millett.

Post-Employment Compensation

Unrelated to Change in Control

Even though we do not have written employment agreements with our NEOs, we have operated under an informal policy that presumes an initial two calendar year term of employment, at the applicable base salary rate. Pursuant to this policy, absent an actual termination of employment or the delivery of a notice of non-renewal by the Company on or before October 1 of a given year (at which time he or she would still have 15 months remaining of his or her employment term), that individual’s employment term, at his or her then-current annual base salary, would be deemed to have been extended for one additional calendar year.

Under this policy, employment is “at will” and we may terminate the employment of a NEO or give notice of non-renewal without regard to cause. If termination of employment or a notice of non-renewal occurs or is delivered prior to October 1, that individual’s term of employment will extend only to the end of the calendar year following the then current year. If neither termination of employment occurs nor delivery of a notice of non-renewal occurs by October 1, that individual’s term of employment will extend to the end of the second calendar year following that October 1. Depending upon when, during the calendar year, a termination of employment or notice of non-renewal occurs, if at all, our NEOs may

have a guaranteed remaining employment term, at his or her current annual base salary, of not less than 15 months nor more than 27 months.

Related to Change in Control

The Company has adopted a “double trigger” Change in Control Protection Plan (the “CIC Plan”), applicable only to our designated NEOs, which provides for specified payments and benefits to our NEOs in the event of a change in control of the Company, accompanied by an involuntary termination of employment, without “cause” by the Company, or for “good reason” by the executive officer, within the period of six months prior to or 24 months following the change in control of the Company. For purposes of the CIC Plan, the terms “change in control,” “cause,” and “good reason” are defined in the plan.

The payments and benefits provided under the CIC Plan are intended to ensure that in the event of a proposed change in control of the Company, our senior executive officers remain focused upon the pending transaction. The Board believes that providing our senior executive officers with transitional compensation protection if their employment ends as a result of a change in control encourages them to act in the best interests of the Company and our shareholders by eliminating personal concerns and uncertainties he or she might otherwise have concerning his or her future employment. The Board further believes that these payments and benefits offer a fair reward for hard work and value creation, assist in retaining our senior executive officers during a time of transition, and provide incentives for them to remain with the Company during periods of uncertainty.

For a summary of the material terms and conditions of the CIC Plan, as well as an estimate of the potential payments and benefits payable to our NEOs under the CIC Plan, see “Potential Payments Upon Termination or Change in Control” below.

Compensation Recovery Policy

We have adopted a Compensation Recovery Policy that provides that in the event that the Company is required to restate its financial results, whether based upon fraud or other financial misconduct attributed to an executive officer and in the further event that any bonus or incentive-based compensation is found to have been based, in whole or in part, upon causative misconduct the Company, after taking into account all applicable factors, is required to take such action as it deems appropriate to recoup from and require reimbursement of any bonus or incentive compensation awarded, paid or otherwise payable to the executive officer, to the extent that the amount was affected by the misconduct or restatement. The recoupment must be initiated within three years following the restatement, and the amount subject to recoupment is limited to the difference between the amount of the bonus or incentive-based compensation actually awarded, paid or payable

to the executive officer and the amount that would have been awarded, paid or payable to the executive officer had the financial results been appropriately reported.

This policy (a) applies to any executive officer, including any NEO, covered by and eligible to receive bonus or incentive-based compensation under any Company plan or program that awards such compensation based, in whole or in part, on company-wide, divisional or plant-level earnings results, and (b) will be deemed incorporated into and made a part of the terms and conditions of employment applicable to each covered executive officer.

Equity Ownership Policy for our Executive Officers

We maintain an equity ownership policy for our executive officers. Under this policy, they are required to own and hold shares of the Company’s common stock with a fair market value as follows:

	Named Executive Officer			Requirement
	Chief Executive Officer			No less than five times base salary
	Chief Financial Officer			No less than three times base salary
	Executive Vice President			No less than two and one half times base salary
	Senior Vice Presidents			No less than two and one half times base salary

The Compensation Committee reviews compliance with the policy annually and requires that the specific ownership levels be met within five years of becoming an executive officer. As of December 31, 2021, each of our NEOs had met his or her specific ownership level requirement. Our Chief Executive Officer, Mr. Millett, is a top 15 shareholder of the Company and owns 1.5% of our outstanding common stock.

Hedging and Pledging of Company Securities

Directors and NEOs may neither engage in any short-term trading in or short-selling of shares of the Company’s common stock, nor may they purchase, sell or otherwise trade in any publicly traded or other options with respect to the Company’s common stock. In addition, they are prohibited from engaging in any hedging transactions or similar monetizing activities involving shares of the Company’s common stock. Our policy also prohibits the acquisition or maintenance of the Company’s shares in a brokerage margin account. Subject to a limited exception set forth in the Policy, including a requirement for pre-approval by the Audit Committee and subject to strict guidelines discouraging any pledging, establishing a limit on the number of shares pledged, requiring demonstration of the pledgor’s ability to retire the loan without the need to liquidate the pledged shares, and, in any event, inhibiting any foreclosure sale during blackout periods, our policy prohibits the use of shares of the Company’s common stock as collateral to secure a loan.

Deductibility of Executive Compensation

The Company’s federal income tax deduction for compensation paid to our chief executive officer, chief financial officer and any other executive officer whose total compensation is required to be reported to shareholders under the Securities Exchange Act of 1934 by reason of such individual being among the three highest compensated executive officers for the tax year, and any executive officer who was subject to the deduction limit in any tax year beginning after December 31, 2016 (the “covered employees”) are limited to $1.0 million per taxable year for each such covered employee, as a result of the Tax Cuts and Jobs Act of 2017 (the “Act”). Although loss of deductibility for such excess compensation results in an increased cost to the Company, the Compensation Committee believes, and believes that our shareholders support the philosophy, that performance-based compensation best aligns our executive officers with long-term shareholder interests, and that such performance-based compensation should be paid, even if non-deductible.

This has guided the Company’s compensation system from inception and is predicated on the notion that individuals will deliver maximum effort and achieve exemplary results when motivated by a compensation system that establishes goals and rewards outstanding performance when such goals are achieved, as measured by objective criteria.

Accounting for Stock-Based Compensation

We follow the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718 (“ASC 718”) for our stock-based compensation awards. ASC 718 requires companies to calculate the grant date fair value of their stock-based awards using a variety of assumptions. This calculation is performed for accounting purposes and reported in the compensation tables below, even though recipients may never realize any value from their awards. ASC 718 also requires companies to recognize the compensation cost of their stock-based awards in their income statements over the period that an employee is required to render service in exchange for his or her award.

Report of the Compensation Committee

The Compensation Committee has reviewed and discussed with management the foregoing Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K and, based on such review and discussion, has recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement and, as incorporated by reference, in our Annual Report on Form 10-K.

2021 Pension Benefits

We did not maintain any defined benefit pension or other actuarial plan for our NEOs during 2021.

2021 Nonqualified Deferred Compensation

We did not maintain any nonqualified defined contribution or other deferred compensation plans or arrangements for our NEOs during 2021.

Potential Payments Upon Termination or Change in Control

Termination of Employment Unrelated to Change in Control

We operate under an informal policy that presumes an original two calendar year term of employment for our NEOs, at each individual’s annual base salary. Pursuant to this policy, absent the delivery of a notice of non-renewal by October 1 of any subsequent year (at which time he or she would have still have 15 months remaining of his or her original two-year employment term), an individual’s term of employment, at his or her then-current annual base salary, would be deemed

sequentially extended for an additional one calendar year term. A timely notice of non-renewal may be delivered with or without cause.

Termination of Employment Related to a Change in Control

The CIC Plan provides for specified payments and benefits to our NEOs in the event of a “Change in Control Termination” by the Company, involving a Change in Control, accompanied by an involuntary termination of employment, without “cause” by the Company, or for “good reason” by our NEO, within the period of six months prior to or 24 months following the Change in Control. For purposes of the CIC Plan, the key defined terms are as follows:

Steel Dynamics, Inc. | 2022 Proxy Statement 65

TABLE OF CONTENTS

■

“Change in Control” means (a) the acquisition of stock ownership of more than 50% of the total voting power, (b) a merger or consolidation in which the Company is not the surviving entity, subject to certain limited conditions, (c) a reverse merger (where the Company is the surviving entity, subject to certain limited conditions), or (d) the sale, transfer or disposition (other than to one or more subsidiaries of the Company) of all or substantially all of the assets of the Company.

■

“Cause” means (a) gross negligence or willful misconduct; (b) a willful and material violation of a state or federal law, which, if publicly known, would injure the Company’s business or reputation; (c) a refusal or willful failure to comply with any specific lawful direction, order, policy, or procedure; (d) conviction (or the entry of a nolo contendere plea) of a felony, or of a misdemeanor that would have a material adverse effect on the Company’s goodwill or commercial relationships, or (e) the substantial and continuing willful refusal, post-transaction, to perform duties ordinarily performed by an employee in the same position, pre-transaction.

■

“Good Reason” means a resignation, associated with a Change in Control, within 30 days following any of the following events: a significant reduction, post-transaction, in the executive officer’s pre-transaction duties, authority, responsibilities, or reporting relationships (other than the mere occurrence, as such, of the Change in Control event itself), or the continued assignment, after due notice of objection, to that executive officer of such reduced duties, authority, responsibilities, or reporting relationships.

The payments and benefits that our NEOs would be eligible to receive are as follows:

■

Acceleration in full, so as to become immediately and completely vested, or acceleration of any applicable deferred settlement dates (subject in all cases to applicable holding periods), of any and all outstanding and unvested stock options, LTIPs, SARs, RSU awards or any other equity-based securities or similar incentives.

■

In the case of our Chief Executive Officer, currently the only “Tier One” executive officer designated by

the Compensation Committee, a lump sum cash payment equal to two times his highest base salary in effect as of the termination date, plus two times the greater of his target annual bonus or average actual bonus for the prior two years under the Annual Plan. In the case of our other NEOs, currently designated “Tier Two” executive officers, a lump sum cash payment equal to one and one-half times his or her highest base salary in effect as of the termination date, plus one and one-half times the greater of his or her target annual bonus or average actual bonus for the prior two years under the Annual Plan.

In the case of both Tier One and Tier Two executive officers, the amount payable is less any amounts to which that individual may otherwise be entitled under any statutory or Company long-term or short-term disability plan, or by reason of any other plans, policies, or practices of the Company that, if and to the extent triggered and implemented, would result in benefit payments, on the occasion of a termination of employment without cause, unrelated to a Change in Control event.

■

If our NEO elects benefits continuation under the Consolidated Omnibus Budget Reconciliation Act of 1985 following termination of employment, payment of the full cost of such benefits (either directly to the executive officer or to the appropriate carrier or administrator at the Company’s election) for the lesser of (a) 24 months or (b) until such time as he or she becomes eligible for reasonably comparable health care benefits from a subsequent employer.

1 The amounts reported in this column assume a remaining employment term of 24 months, at our NEO’s then-current annual base salary. Depending upon the date of notice of non-renewal or termination, however, the actual remaining employment term could be as short as 15 or as long as 27 months.

2 Our NEOs participate in the group term life insurance program with cash benefits expected to be equal to two times his or her base salary in effect as of the termination date. A portion of the aggregate death benefits is currently self-funded by the Company. Potential death payments assume the Compensation Committee approves of acceleration of outstanding equity awards. Acceleration is not automatic.

TABLE OF CONTENTS

CEO Pay Ratio

As required by Item 402(u) of Regulation S-K, and in accordance with applicable SEC interpretive guidance, we are providing the following information about the ratio of the annual total compensation of our Chief Executive Officer to the annual total compensation of our median employee, as of December 31, 2021. This ratio is a reasonable estimate, calculated in a manner consistent with SEC rules.

Our principal executive officer is Mr. Mark Millett, Chairman, President and Chief Executive Officer. Mr. Millett had annual total compensation of $10,999,918 in 2021, as reported in the 2021 Summary Compensation Table. Our median employee’s annual total compensation in 2021 was $126,721. Therefore, we estimate that Mr. Millett’s annual total compensation for 2021 was 87 times that of our median employee.

To identify our median compensated individual, we analyzed the compensation of all part time and full time employees of the Company and its consolidated subsidiaries, which amounted to 10,729 individuals, as of December 31, 2021. The compensation of permanent employees who did not work for the entire year has been annualized. The Company’s consistently applied compensation measure was total annual gross compensation paid to all employees for the Company’s last completed fiscal year 2021. We then utilized the same rules which we apply to the calculation of total compensation of the Company’s NEOs, as reflected in the Summary Compensation Table to determine the annual total compensation of our median employee.

Proposal No. 3

Advisory Vote
to Approve the
Compensation of
the Named
Executive Officers

We are asking our shareholders to approve the compensation paid to our NEOs for 2021, as disclosed in this Proxy Statement. This vote, which is sometimes referred to as a “say-on-pay vote,” is required by the federal securities laws. The vote is advisory only, and, accordingly is not binding on the Company, the Board or the Compensation Committee. Although the vote is non-binding, the Compensation Committee and the Board will nonetheless carefully consider the outcome of the vote when making future compensation decisions.

At the 2021 Annual Meeting, the Company’s “say-on-pay” proposal with respect to our 2021 executive compensation program was approved with 93% of the votes cast in favor of the compensation of our NEOs. Accordingly, we carried our long-standing compensation philosophy and pay practices materially unchanged into 2021.

As described in the preceding CD&A, the Company continues to primarily rely upon two performance-based incentive compensation programs, the Annual Plan and long-term equity incentive compensation awards. Together, they provide over 84% of our Chief Executive Officer’s and over 79% of our average named executive officer’s target total direct compensation opportunities and effectively implement our “pay-for-performance” philosophy. These principal pay components provide a straightforward and balanced approach to identifying, assessing and rewarding executive performance.

We encourage you to read the CD&A which describes the details of our executive compensation program and the decisions made by the Compensation Committee in 2021. Our executive compensation program is designed to reward performance in a simple and effective way, encouraging our executive team to operate as a high-performing team, focusing on long-term value creation.

The entire Steel Dynamics team achieved record performance during 2021. We achieved numerous milestones and performed at the top of our industry both operationally and financially. Most importantly, we did it safely, operating better than key industry benchmarks. We achieved record steel shipments of 11.2 million tons and record steel fabrication shipments of 789,000 tons with 2021 consolidated revenues at $18.4 billion. We achieved record earnings at each of our three primary operating platforms which resulted in record consolidated operating income of $4.3 billion and record consolidated net income of $3.2 billion.

Steel Dynamics, Inc. | 2022 Proxy Statement 69

TABLE OF CONTENTS

The Board believes that our executive compensation program and compensation-related risk mitigation policies and practices effectively align our NEOs’ interests with those of our shareholders in the pursuit of long-term value creation through exemplary performance.

Accordingly, the Board is requesting your approval, on an advisory basis, of the following resolution:

“RESOLVED, that the shareholders of Steel Dynamics, Inc. approve, on an advisory basis, the compensation for 2021 paid to the Named Executive Officers, as disclosed in the Proxy Statement for the 2022 Annual Meeting of Shareholders, pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the 2021 Summary Compensation Table and the other related tables, and the accompanying narrative set forth in this Proxy Statement.”

The Board of Directors recommends a vote FOR the approval of the compensation of the Named Executive Officers.

Other Matters

We do not intend to bring any other matters before the Annual Meeting, nor are we aware of any other matters that are to be properly presented to the Annual Meeting by others. If another matter does properly come before the Annual Meeting or any adjournments thereof, then,

depending upon the nature of the issue and if within the scope of their authority, it is the intention of the persons named in the Proxy to vote such Proxy in accordance with their best judgment on such matter.
