Shareholder Engagement

We maintain an ongoing, proactive outreach effort with our shareholders. Throughout the year, members of our Investor Relations team and senior management, including our Chief Executive Officer ("CEO"), Chief Financial Officer ("CFO"), and other named executive officers ("NEO" or "NEOs"), engage with our shareholders to seek their input, to remain well-informed regarding their perspectives, and to help increase their understanding of our business. In particular, we leverage the discussions to cover topics of interest to our shareholders, including our performance, strategy, risk management, corporate governance, ESG initiatives, and executive compensation. The feedback received from our shareholder outreach efforts is communicated to and considered by the Board, and our engagement activities have produced valuable feedback that helps inform our decisions and our strategy, when appropriate.

Compensation Highlights

Our shareholders continue to show strong support for our pay-for-performance philosophy (receiving 99% of votes cast in favor of our compensation program during the 2023 Annual Meeting). We believe weighting a significant portion of our named executive officers’ compensation with performance-based compensation and value creation in the form of stock appreciation aligns with our shareholders' expectations. With these expectations in mind, the HR Committee designed a compensation package for the CEO that was 84% at risk and for the other NEOs 67% at risk.

The HR Committee modified the prior year's compensation program to reflect the priorities of the business and its shareholders. For the 2023 annual incentive program (the "AIP"), we introduced new metrics to further focus management on cost and expense control by including a measure of the percentage of non-production costs to our revenue for the Corporate Plan and a metric of Adjusted EBITDA margin for the Group President Plans. We continued to align management's interest with those of our shareholders by linking the payout of the performance-based portion of our long-term compensation program to our financial performance and our Total Shareholder Return ("TSR") performance relative to the S&P SmallCap 600 Index.

Proposal One Election of Nominated Directors
10 Current Members	The Board of Directors currently consists of ten members. Mr. Ronald J. Gafford is retiring when his term expires in 2024 and will not stand for re-election at the Annual Meeting. On the recommendation of the G&S Committee, the Board has nominated the nine incumbent candidates to be re-elected at the Annual Meeting. If elected, each of the directors will serve for a one-year term expiring at the 2025 Annual Meeting of Shareholders, or when their successors are duly elected and qualified or earlier upon death, resignation, retirement, disqualification, or removal.
9 Candidates for re-election	All of the nominees are incumbent directors, and, pursuant to Arcosa's Amended and Restated Bylaws, an incumbent director nominee who is not elected is required to tender his or her resignation for consideration by the G&S Committee and the Board (with the affected director recusing himself or herself from the deliberations). The Board will be free to accept or reject the resignation and will make its decision known publicly within 90 days of certification of the vote results. If a director’s resignation is accepted by the Board, then the Board may fill the resulting vacancy. Each nominee has agreed to be named in this Proxy Statement and to serve if elected. We have no reason to believe that any of the nominees would be unable to serve if elected, but, if any nominee is unavailable for election, the proxy holders may vote for another nominee proposed by the Board, in which case your shares will be voted for such other nominee. The Board of Directors believes that each of the director nominees possesses the qualifications described in the "Director Nomination Process" section. The "Director Nominees" section contains biographical information about each of the director nominees, including a description of the experience, qualifications, attributes, and skills that led the Board to conclude that the individual should be nominated for election as a director of Arcosa.
1-year Term expiring in 2025
	"FOR" The Board of Directors recommends that you vote FOR each of the Nominees for Director.

Table of Contents Proposal One

Director Nomination Process

The G&S Committee is responsible for recommending qualified candidates to the Board for nomination. In accordance with our Corporate Governance Principles, the G&S Committee should consider the following qualifications in making its recommendation of candidates to serve as a director of Arcosa: (i) the candidate's depth of experience at the policy-making level in business, government, or education; (ii) the candidate's ability to make a meaningful contribution to the Board’s oversight of the business and affairs of Arcosa and a willingness to exercise independent judgment; and (iii) whether the candidate has an impeccable reputation for honest and ethical conduct in both professional and personal activities. In addition, the G&S Committee examines a candidate’s availability and willingness to devote time to Board duties, the candidate’s ability to make analytical and probing inquiries, and financial independence to ensure he or she will not be financially dependent on director compensation.

The G&S Committee identifies potential nominees by asking, from time to time, current directors and executive officers for their recommendations of persons meeting the criteria described above who might be available to serve on the Board. The G&S Committee may also engage qualified firms that specialize in identifying director candidates. As described below, the G&S Committee will also consider candidates recommended by shareholders.

Once a person has been identified as a potential candidate, the G&S Committee makes an initial determination regarding the need for additional Board members to fill vacancies or expand the size of the Board. If the G&S Committee determines that additional consideration is warranted, the G&S Committee will review such information and conduct interviews as it deems necessary to fully evaluate each director candidate. In addition to the qualifications of a candidate, the G&S Committee will consider such relevant factors as it deems appropriate, including the current composition of the Board, the evaluations of other prospective nominees, and the need for any required expertise on the Board or one of its committees. The G&S Committee considers potential candidates in light of the skills, experience, and attributes possessed by current directors and as identified by the Board. The G&S Committee also contemplates multiple dynamics that promote and advance diversity among its members. Although the G&S Committee does not have a formal diversity policy, the G&S Committee considers a number of factors regarding diversity of personal and professional backgrounds (both domestic and international), national origins, specialized skills and acumen, and breadth of experience in industry, manufacturing, financial transactions, and business combinations.

The G&S Committee will consider director candidates recommended by shareholders. In considering candidates submitted by shareholders, the G&S Committee will take into consideration the needs of the Board and the qualifications of the candidate. To have a candidate considered by the G&S Committee, a shareholder must submit the recommendation in writing and must include the following information:

•the name of the shareholder, evidence of the person’s ownership of Arcosa stock, including the number of shares owned and the length of time of ownership, and a description of all arrangements or understandings regarding the submittal between the shareholder and the recommended candidate; and

•the name, age, business address, and residence address of the candidate, the candidate’s resumé or a listing of his or her qualifications to be a director of Arcosa, and the person’s consent to be a director if selected by the G&S Committee, nominated by the Board, and elected by the shareholders.

The shareholder recommendation and information described above must be sent to the Corporate Secretary at 500 N. Akard St., Suite 400, Dallas, Texas 75201, and must be received by the Corporate Secretary not less than 120 days prior to the anniversary date of the date that Arcosa’s Proxy Statement was released in connection with the previous year’s Annual Meeting of Shareholders in order to be included in Arcosa's Proxy Statement and form of proxy relating to the next Annual Meeting of Shareholders pursuant to Securities and Exchange Commission ("SEC") Rule 14a-8. The G&S Committee’s evaluation process will not vary based on whether or not a candidate is recommended by a shareholder.

  19

Corporate Governance

Our business affairs are managed under the direction of the Board in accordance with the General Corporation Law of the State of Delaware, our Restated Certificate of Incorporation, and our Amended and Restated Bylaws. The role of the Board is to oversee our management for the benefit of the shareholders. This responsibility includes monitoring senior management’s conduct of our business operations and affairs; reviewing and approving our financial objectives, strategies, and plans; risk management oversight; evaluating the performance of the CEO and other executive officers; and overseeing our policies and procedures regarding corporate governance, legal compliance, ethical conduct, and maintenance of financial and accounting controls.

The Board has adopted Corporate Governance Principles, which are reviewed annually by the G&S Committee. We have a Code of Conduct, which is applicable to all of our employees, including the CEO, the CFO, and principal accounting officer and controller, as well as members of the Board. We intend to post any amendments to or waivers from our Code of Conduct on our website at ir.arcosa.com to the extent applicable to an executive officer, principal accounting officer and controller, or a director of Arcosa. The Corporate Governance Principles and the Code of Conduct are available on our website at ir.arcosa.com under the heading "Corporate Governance — Additional Governance Documents."

Independence of Directors

The Board makes all determinations with respect to director independence in accordance with the New York Stock Exchange ("NYSE") listing standards and the rules and regulations promulgated by the SEC. In addition, the Board established certain guidelines to assist it in making any such determinations regarding director independence (the "Independence Guidelines"), which are available on our website at ir.arcosa.com under the heading "Corporate Governance — Additional Governance Documents — Arcosa Categorical Standards of Director Independence." The Independence Guidelines set forth commercial and charitable relationships which may not rise to the level of material relationships that would impair a director’s independence as set forth in the NYSE listing standards and SEC rules and regulations. The determination of whether such relationships as described in the Independence Guidelines actually impair a director’s independence is made by the Board on a case-by-case basis.

The Board undertook its annual review of director independence and considered transactions and relationships between each director, or any member of his or her immediate family, and Arcosa and its subsidiaries and affiliates. In making its determination, the Board applied the NYSE listing standards and SEC rules and regulations, together with the Independence Guidelines.

As a result of its review, the Board affirmatively determined that the following directors are independent of Arcosa and its management under the standards set forth in the NYSE listing standards and the SEC rules and regulations: Joseph Alvarado, Rhys J. Best, Jeffrey A. Craig, Steven J. Demetriou, John W. Lindsay, Kimberly S. Lubel, Julie A. Piggott, and Melanie M. Trent. The Board determined that Antonio Carrillo is not independent because of his employment by Arcosa.

Board Leadership Structure

As our independent, non-executive Chairman of the Board, Mr. Best (i) presides over all meetings of the Board, non-management executive sessions, and shareholder meetings; (ii) reviews and approves meeting agendas, meeting schedules, and other information, as appropriate; (iii) acts as a liaison between the outside directors and management; (iv) consults on shareholder engagement and governance matters; (v) has the right to call special board or shareholder meetings; and (vi) performs such other duties as the Board requires from time to time. Having a separate non-executive Chairman allows our CEO to focus on operating and managing Arcosa and leverages our Chairman’s experience in guidance and oversight. While the Board believes that this structure is currently in the best interests of Arcosa and its shareholders, the Board does not have

20

Table of Contents Corporate Governance

a policy with respect to separating the Chairman of the Board and the CEO roles and could adjust the structure in the future as it deems appropriate.

Our Audit Committee, G&S Committee, and HR Committee are each comprised entirely of independent directors, providing a structure for strong independent oversight of our management.

Board Succession

The G&S Committee and the full Board routinely discuss board succession. Board composition is one of the most critical areas of focus for the Board. Having the right mix of directors who bring diverse perspectives, business and professional experiences, and skills provides a foundation for robust dialogue, informed advice, and collaboration. The Board considers current Board skills, composition, tenure, and anticipated retirements to identify gaps that may need to be filled through Board succession planning and the Board refreshment process. The Board strives to ensure an environment that encourages diverse critical thinking and values innovative, strategic discussions to achieve a higher level of success for Arcosa.

On February 29, 2024, Ronald J. Gafford announced that he would not be standing for re-election at the 2024 Annual Meeting and would retire from the Board after 25 years of dedicated service to both Arcosa and our Former Parent. With Mr. Gafford's retirement, the Board intends to resize the Board to consist of nine members.

Board Meetings and Committees

The Board holds regular and special meetings and spends such time on our affairs as their duties require. The Board held five meetings and a total of 14 committee meetings in 2023. The Board also meets regularly in non-management executive sessions. In 2023, all directors of Arcosa attended at least 75% of the meetings of the Board and the committees on which they served. Each director also attended the 2023 Annual Meeting of Shareholders, which is required pursuant to Arcosa's Corporate Governance Principles.

The standing committees of the Board are the Audit Committee, G&S Committee, and HR Committee. Each of the committees is governed by a charter, current copies of which are available on our website at ir.arcosa.com under the heading "Corporate Governance — Board Committees & Charters." Mr. Carrillo, the CEO and President of Arcosa, and Mr. Best, our non-executive Chairman of the Board, do not serve on any Board committees. Director membership of the committees and the number of committee meetings held in 2023 are identified below.

The Role of the Compensation Consultant

For 2023, the HR Committee retained Pay Governance LLC (the "Compensation Consultant") to provide a variety of executive compensation consultant services as an independent compensation consultant. The services provided by the Compensation Consultant in 2023 included: (i) reviewing and assisting in the design of our executive compensation programs, (ii) providing insight into executive compensation practices used by other companies, (iii) benchmarking our executive compensation pay levels with relevant peer survey data, (iv) providing proxy disclosure information for comparator companies, and (v) providing input to the HR Committee on the risk assessment, structure, and overall competitiveness of our executive compensation programs.

The Compensation Consultant’s ownership structure, limited service lines, and policies and procedures are designed to ensure that such Compensation Consultant’s work for the HR Committee does not raise any conflicts of interest. The amount of fees paid in 2023 to the Compensation Consultant by Arcosa represented less than one percent (1%) of such Compensation

24

Table of Contents Corporate Governance

Consultant’s total annual revenues for 2023. The internal policies of the Compensation Consultant prohibit its members, partners, consultants, and employees from engaging in conduct that could give rise to conflicts of interest and from acquiring securities in their client organizations. The employees of the Compensation Consultant providing consulting services to the HR Committee have no other business or personal relationship with any member of the HR Committee or any executive officer of Arcosa. After a review of these factors and the considerations outlined in applicable SEC and NYSE rules, the HR Committee has concluded that the work of the Compensation Consultant has not raised any conflicts of interest and that the Compensation Consultant is independent from Arcosa and from management.

The Role of Management

The CEO, the CFO, and the Chief Human Resources Officer work with the HR Committee and the Compensation Consultant to develop the framework and to design the plans for all compensation components. The CEO and CFO recommend the financial performance measurements for the annual incentive awards and the long-term performance-based equity awards, subject to HR Committee approval. The CFO certifies the achievement of these financial performance measures. The HR Committee recommends the CEO's compensation to the independent directors for their approval. The CEO makes recommendations to the HR Committee on compensation for each of the other named executive officers, as well as other senior leaders.

The Role of the HR Committee

Throughout the year, the CEO provides the HR Committee with his ongoing assessment of the performance of the other named executive officers. These assessments provide background information for any adjustment to base salary, annual incentives, or long-term incentives. Both annual incentives and long-term incentives are established with threshold, target, and maximum payout levels.

The HR Committee realizes that benchmarking and comparing peer group proxy disclosure data require certain levels of interpretation due to the complexities associated with executive compensation plans. The HR Committee uses the benchmarking information and the peer group proxy disclosure data provided by the Compensation Consultant as general guidelines and makes adjustments to compensation levels based on what the HR Committee believes is in the best interests of our shareholders. The HR Committee uses its judgment and bases its consideration of each executive’s compensation on performance in respect to the value of the executive’s contributions to Arcosa, the executive’s tenure, and peer survey data that establishes the ranges against which compensation is benchmarked.

Compensation Committee Interlocks and Insider Participation

Messrs. Alvarado, Gafford, and Lindsay, and Ms. Lubel served on the HR Committee during the last completed fiscal year. None of the members of the HR Committee has ever served as an executive officer or employee of Arcosa or any of its subsidiaries. There are no compensation committee interlocks.

Board’s Role in Risk Oversight

While management is responsible for the day-to-day management and mitigation of risk, our Board has ultimate responsibility for risk oversight. Management reviews and discusses risks with the Board as part of the business and operating review conducted at each of the regular meetings of the Board. While the Board has primary responsibility for overseeing Arcosa’s risk management, each committee of the Board also considers risk within its area of responsibility and regularly reports back to the Board on its risk oversight activities.

The Audit Committee (i) assesses major financial risk exposures and steps taken by management to address the same, (ii) is responsible for the review and assessment of information technology and cybersecurity risk exposures and the steps taken to monitor and control those exposures, and (iii) reviews risks identified during the internal and external auditors’ risk assessment procedures. The HR Committee reviews risks arising from our executive compensation programs and management succession planning. As a result of the HR Committee's review, management and the HR Committee have concluded that the Company's compensation policies and practices are not reasonably likely to have a material adverse effect on the Company. The G&S Committee oversees risks related to our governance structure, certain ESG-related matters, and director compensation programs.

  25

Corporate Governance Table of Contents

Risk Assessment of Compensation Policies and Practices

The Compensation Consultant performed a risk assessment with respect to our 2023 incentive compensation plans applicable to our executive officers. Based on this review, the Compensation Consultant concluded that our executive incentive programs do not encourage excessive risk-taking behaviors. We also conducted a detailed risk assessment of our 2023 compensation policies and practices (the "Compensation Policies") for our employees, including our executive officers, and assessed the likelihood and potential impact of the risk presented by the Compensation Policies. Participants in the risk assessment included our management, human resources group, internal audit group, and the HR Committee. Based on this review, management has concluded that sufficient controls exist to mitigate the risks related to the Compensation Policies.

Communications with Directors

The Board has established a process to receive communications by mail from shareholders and other interested parties. Shareholders and other interested parties may contact any member of the Board or the non-management directors as a group, any Board committee, or any chair of any such committee. All such correspondence should be sent to the Corporate Secretary of Arcosa at 500 N. Akard St., Suite 400, Dallas, Texas 75201.

All communications received as set forth in the preceding paragraph will be opened by the office of the Corporate Secretary for the sole purpose of determining whether the contents represent a message to directors. Any contents that are not in the nature of advertising, promotions of a product or service, or offensive material will be forwarded promptly to the addressee. In the case of communications to the Board or any group or committee of directors, the Corporate Secretary will make sufficient copies of the contents to send to each director, group, or committee to which the envelope is addressed.

Employee, Officer, and Director Pledging and Hedging Policy

Arcosa has adopted a policy prohibiting pledging and hedging. The policy prohibits officers, directors, and employees of Arcosa and their respective related persons from (i) selling Arcosa securities short, (ii) pledging or hypothecating any Arcosa securities (e.g. using Arcosa securities for margin loans or to collateralize other indebtedness), or (iii) engaging in derivative transactions, including, without limitation, hedging, puts and calls, or other transactions involving Arcosa securities.

26

Transactions with Related Persons

Review, Approval, and Ratification of Transactions with Related Persons

The G&S Committee has adopted a Policy and Procedures for the Review, Approval, and Ratification of Related Person Transactions. In accordance with the written policy, the G&S Committee, or the chair of such committee, as applicable, is responsible for the review, approval, and ratification of all transactions with related persons that are required to be disclosed under the rules of the SEC. Under the policy, a related person includes any of Arcosa’s directors, executive officers, certain shareholders, and any of their respective immediate family members. The policy applies to any "Related Person Transaction," which is a transaction in which Arcosa participates, a related person has a direct or indirect material interest, and the amount exceeds $120,000. Under the policy, the Chief Legal Officer (the "CLO") will review potential transactions and, in consultation with the CEO and CFO, will assess whether the proposed transaction would be a Related Person Transaction. If the CLO determines the proposed transaction would be a Related Person Transaction, the proposed transaction is submitted to the G&S Committee, or the chair of such committee, as applicable, for review and consideration. In reviewing Related Person Transactions, the G&S Committee, or the chair of such committee, as applicable, shall consider all relevant facts and circumstances available, including, but not limited to the following:

•the benefits to Arcosa of the Related Person Transaction;

•the impact of a director’s independence if the related person is a director, an immediate family member of a director, or an entity in which a director is a partner, shareholder, or executive officer;

•the availability of other sources for comparable products and services;

•the terms of the transaction; and

•the terms available to unrelated third parties or employees generally.

After reviewing such information, the G&S Committee, or its chair, as applicable, may approve the Related Person Transaction if the G&S Committee or the G&S Committee chair concludes in good faith that the Related Person Transaction is in, or is not inconsistent with, the best interests of Arcosa and its shareholders.

Under the policy, the HR Committee must approve hiring of immediate family members of executive officers or directors and any subsequent material changes in employment or compensation. In 2023, Arcosa did not enter into any Related Person Transaction of the type required to be disclosed under Item 404 of Regulation S-K under the Exchange Act.

Proposal Two Advisory Vote to Approve Named Executive Officer Compensation
Arcosa's executive compensation program:	Arcosa seeks approval, on an advisory basis, from its shareholders of the compensation of its named executive officers as described in this Proxy Statement.
Encourages high levels of performance and accountability + Aligns interests of executives and shareholders + Links compensation to business objectives and strategies
	As described in the "Compensation Discussion and Analysis," Arcosa’s executive compensation program (i) encourages high levels of performance and accountability, (ii) aligns the interests of executives with those of shareholders, and (iii) links compensation to business objectives and strategies. This proposal provides shareholders the opportunity to approve, or not approve, Arcosa’s executive compensation program through the following resolution: "RESOLVED, that the compensation paid to Arcosa’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and the related narrative discussion, is hereby approved." Because this is an advisory vote, it will not be binding upon the Board. However, the HR Committee will take into account the outcome of the vote when considering future executive compensation arrangements. After the 2024 Annual Meeting, the next advisory vote to approve the compensation of the named executive officers will occur at the 2025 Annual Meeting of Shareholders unless the Board modifies its policy on the frequency of holding such advisory votes.
	"FOR" The Board of Directors recommends that you vote FOR approval of this resolution.

Executive Compensation
Compensation Discussion and Analysis

This Compensation Discussion and Analysis ("CD&A") describes our executive compensation philosophy and pay programs in 2023.

2023 COMPENSATION PROGRAM PHILOSOPHY

Our executive compensation program reflects our pay-for-performance philosophy. The HR Committee utilizes a combination of fixed and variable pay elements in order to achieve the following objectives:

	Support Arcosa’s overall business strategy and results to drive long-term shareholder value creation without incentivizing excessive risk taking.		Attract, retain, and motivate key executives by providing market-competitive total compensation opportunities.
	Emphasize a strong link between pay and performance with predefined short- and long-term performance goals that place the majority of total compensation at risk.		Align executive and investor interests by establishing market-relevant metrics that address shareholder expectations.

2023 NAMED EXECUTIVE OFFICERS

For 2023, our NEOs and their titles were:

Name	Principal Position
Antonio Carrillo	President and CEO
Gail M. Peck	CFO
Kerry S. Cole	Group President
Jesse E. Collins, Jr.	Group President
Reid S. Essl	Group President
Bryan P. Stevenson	CLO

2023 Program Highlights

ANNUAL INCENTIVE PROGRAM

Payouts to the NEOs and other key executives under our 2023 AIP reinforced our strong pay-for-performance philosophy. In designing the AIP for 2023, the HR Committee approved performance metrics that were in furtherance of our strategic goals and in line with our initial 2023 earnings guidance. The HR Committee linked a significant portion of each of the NEO’s AIP awards to the performance of the business at the enterprise level or the group level of businesses, as applicable.

In 2023, the HR Committee approved four AIP plans for the NEOs -- the Corporate Plan and three Group President Plans, with each Group President Plan comprised of the businesses reporting to the particular Group President.

CORPORATE PLAN (Antonio Carrillo, Gail Peck, and Bryan Stevenson) Enterprise	GROUP PRESIDENT PLAN A (Reid Essl) Natural Aggregates Recycled Aggregates Specialty Materials
GROUP PRESIDENT PLAN B (Kerry Cole) Utility and Related Structures Marine Products	GROUP PRESIDENT PLAN C (Jesse Collins) Steel Components Wind Towers Shoring Products

The HR Committee approved the design of the 2023 AIP plans to include a measure of the percentage of non-production costs to our revenue ("Adjusted Corporate SE&A") and Adjusted EBITDA margin ("Group Adjusted EBITDA Margin") as new metrics for the Corporate and Group President Plans, respectively. The new design focused management's attention on cost and expense control for each of the Corporate Plan and the Group President Plans to complement the already established profitability goals reflected in the Adjusted EBITDA metrics.

Corporate Plan (CEO, CFO, CLO)		Group President Plans (3 Group Presidents)
Performance Metric	Weighting	Performance Metric	Weighting
Enterprise Adjusted EBITDA	60%	Group Adjusted EBITDA	60%
Adjusted Corporate SE&A	20%	Group Adjusted EBITDA Margin	20%
Execution of Strategic Initiatives	20%	Execution of Strategic Initiatives	20%

Table of Contents Executive Compensation

LONG-TERM INCENTIVE PROGRAM

In 2023, the performance-based restricted stock units ("PBRSUs") for our NEOs remain weighted as follows:

n Average Pre-Tax Return on Capital n rTSR n Cumulative Adjusted Earnings per Share

We continued to align management's interest with those of our shareholders by linking the payout of the performance-based portion of our long-term compensation ("LTI") program to our financial performance and our TSR performance relative to the S&P SmallCap 600 Index ("rTSR").

2023 Performance Highlights

In 2023, we continued to execute on the four strategic pillars of our long-term vision.

Grow in attractive markets where we can achieve sustainable competitive advantages	Reduce the complexity and cyclicality of the overall business	Improve long-term returns of invested capital	Integrate Environmental, Social, and Governance initiatives (ESG) into our long-term strategy

We again set a new record for financial performance exceeding the overall target set by the Board and the HR Committee. Our $367.6 million in Enterprise Adjusted EBITDA increased 32% compared to 2022, normalizing for the divestiture of the Storage Tanks business in 2022, and was fueled by double-digit increases in each of our three segments.

We executed against strategic initiatives important to driving shareholder interest and value. Highlights, which the HR Committee considered in connection with the evaluation of the execution of the strategic initiatives component in the payout of the 2023 AIP, include:

ESG (including Safety) Tracking ahead of 10% GHG emissions reduction goal by 2026. Advanced the ARC 100 Safety Culture Program throughout our plants. We recorded our second lowest total reportable incidents rate since Arcosa's inception. We engaged with our communities in various charitable ventures.	Growth 32% Adjusted EBITDA growth at the Enterprise level and double-digit Adjusted EBITDA growth at the segment level. Successfully completed six bolt-on acquisitions in our growth businesses for approximately $120 million. Opened new or expanded plants in Oklahoma, New Mexico, and Florida, expanding production capabilities and geographic footprints.	Working Capital Improved our working capital days across the Enterprise with noted improvement in our cyclical businesses.

Shareholder Engagement and Say-on-Pay Results

The Board and the HR Committee value the benefits of maintaining a dialogue with our shareholders and understanding their views. During 2023, we engaged in a robust shareholder outreach program with 75% of our top 25 holders of our stock, including shareholder engagement with our Board, where we and the Board solicited the feedback of our shareholders on topics including our performance, strategy, risk management, corporate governance, ESG-related initiatives, and executive compensation. Members of our Investor Relations team along with certain of our senior executives, including at times our CEO, CFO, and Group Presidents, met with shareholders in both in-person and virtual engagements throughout the year. We partnered with an investor relations firm to perform a perception study providing further insight into the drivers important to our shareholders. The continued receipt of positive feedback from our shareholder engagement program signals valuable support from our shareholders to our approach to executive compensation.

99% SHAREHOLDER VOTE in favor of Say-on-Pay at 2023 Annual Meeting

The HR Committee considered the result of our say-on-pay vote as an additional sign of our shareholders' support of our executive compensation philosophy and plans. Our NEOs' 2023 compensation will be the subject of the advisory, non-binding say-on-pay vote at the 2024 Annual Meeting. The HR Committee will consider the outcome of future say-on-pay votes and shareholder engagement as it evaluates the design of the executive compensation programs and the related specific compensation decisions.

Our Compensation Policies and Practices

We have adopted the following compensation practices, which are intended to promote strong governance and alignment with shareholder interests:

What We Do:
	Pay for Performance. We believe in a "pay for performance" philosophy in which a majority of our NEOs’ compensation, as well as a significant portion for other employees throughout the organization, is linked to achievement of specific annual and long-term strategic and financial goals and the realization of increased shareholder value. Approximately 84% of our CEO’s compensation and, on average, 67% of all other NEOs' compensation is "at risk" compensation, comprised of incentive and equity-based compensation.
	Maintain Stock Ownership Guidelines. To further align the interests of our executives and directors with those of our shareholders and to assure that our executives and directors own meaningful levels of Common Stock throughout their tenures with Arcosa, the HR Committee has adopted stock ownership guidelines for our non-employee directors, NEOs, and other senior officers as designated by the HR Committee. The directors, NEOs, and certain other senior officers have five years from the date of adoption of the policy, or from the date such director, NEO, or senior officer becomes subject to the policy, to meet their required stock ownership levels. Each of our directors, NEOs, and participating senior officers has either met or is on track to achieve these ownership guidelines within the five-year compliance period. The required level of stock ownership is determined by the number of shares of Common Stock equal in value to the following multiples:
	Title	Ownership Level
	Chief Executive Officer	5 times base salary
	Chief Financial Officer	3 times base salary
	Other Senior Officers	2 times base salary
	Board of Directors	5 times annual board cash retainer

Executive Compensation Table of Contents

	Require Double Trigger for Receipt of Severance Payments. Our NEOs participate in the 2022 Arcosa, Inc. Change in Control Severance Plan (the "2022 CIC Plan"), which contains a "double trigger" provision that requires both a change in control of Arcosa and a qualifying termination of the participating executive in order for such executive to receive severance payments and accelerated vesting of equity awards, except for those certain awards granted prior to December 6, 2018 by our Former Parent. We believe that the 2022 CIC Plan provides a mechanism for retaining our NEOs' services and eliminating the distractions inherent in change in control events. See "Other Compensation Plans" and "Potential Payments Upon Termination or Change in Control."
	Maintain a Clawback Policy. The Board has adopted a clawback policy compliant with New York Stock Exchange listing requirements that requires the HR Committee to recover excess compensation received by our Section 16 Officers pursuant to short-term or long-term incentive compensation plans if, subsequent to any compensation being received, there has been an accounting restatement with respect to Arcosa's financial statements.
	Retain an Independent Compensation Consultant. The HR Committee directly retains an independent compensation consultant each year to provide guidance on executive compensation-related matters, to perform an annual total compensation study including compensation benchmarking information from peer group companies, and to advise on matters relating to executive and director compensation.
	Prohibit Hedging and Pledging Our Shares. Our insider trading policy prohibits executive officers, employees, and directors from pledging our securities or engaging in hedging or short-term trading of our securities, including, without limitation, short sales or transactions in puts, calls, or other derivative transactions. See "Corporate Governance—Employee, Officer, and Director Pledging and Hedging Policy."

What We Don't Do:
X	Dividends on Unvested Restricted Stock Units. During the vesting period, recipients do not receive dividend payments on time-based or performance-based restricted stock units issued by Arcosa. Unvested PBRSUs also do not accrue dividend equivalents. Unvested awards of TBRSUs accrue dividend equivalents, which will be paid in cash only if and when such awards vest.
X	Excise Tax Gross-Ups for Participants in the 2022 CIC Plan. The 2022 CIC Plan provides that no excise or other tax gross-ups will be paid under the plan, and that severance benefits will be available only upon voluntary termination of employment for "good reason" by a participating officer or for termination without "cause" by Arcosa within six months prior to and in connection with a "change in control" or within two years following a "change in control." See "Other Compensation Plans" and "Potential Payments Upon Termination or Change in Control."
X	Employment Contracts. None of the NEOs or senior officers have employment contracts.

Compensation Approach and Benchmarking

COMPENSATION APPROACH

The HR Committee, in consultation with management and its Compensation Consultant, oversees our executive compensation philosophy and reviews and approves compensation for our NEOs and other key executives, with the exception of the CEO. The independent directors of the Board approve the CEO’s compensation following a review and recommendation by the HR Committee.

The HR Committee retains the Compensation Consultant, who provides guidance on executive compensation-related matters and who performs an annual total compensation study. The Compensation Consultant provides compensation benchmarking information (the "Peer Survey Data") for our NEOs and other key executives from peer group companies (the "Peer Group"). After evaluating the Peer Survey Data, our CEO discusses with the HR Committee his evaluation of each NEO and other key executives, excluding himself. The Compensation Consultant’s analyses, along with the CEO’s compensation

34

Table of Contents Executive Compensation

recommendations for each NEO and other key executives, are presented to the HR Committee for consideration and approval in determining NEO and other key executive compensation. The HR Committee, following a review and in consultation with the Compensation Consultant, recommends the CEO’s compensation to the independent directors of the Board for their approval.

The HR Committee generally targets the total target compensation of the NEOs and other key executives within a competitive range around the median of the Peer Survey Data. The HR Committee considers the targeted range and develops a total target compensation amount for each NEO and other key executives using the objectives described above and the Peer Survey Data as general guidelines. The HR Committee considers additional internal and external factors when making individual compensation decisions, including overall experience and scope of role, individual performance, internal reporting structure, internal equity, and our overall pay objectives. This approach supports our philosophy of driving performance and accountability.

BENCHMARKING AND PEER SURVEY DATA FOR 2023 COMPENSATION

We engaged the Compensation Consultant to assist in designing our executive compensation program, including review of our compensation benchmarking Peer Group. In September 2022, the HR Committee, with the advice of the Compensation Consultant, reviewed and approved our Peer Group for use in benchmarking 2023 compensation. The Compensation Consultant used regression analysis to provide size-adjusted market data for a company of our revenue size to the HR Committee. The Peer Group was developed based on the following attributes:

Industry	Companies that operate in a similar industry
6
Growth Profile	Similar revenue size (target 0.5 to 4.0 times the size of Arcosa)
6
Executive Positions	Similar positions in breadth, complexity, and scope of responsibility
6
Talent	Competition for executive talent

  35

Executive Compensation Table of Contents

Based on these attributes, the HR Committee approved the following companies as our Peer Group for use in benchmarking 2023 compensation:

Arcosa Peer Companies
	AZZ Inc.	ESAB Corporation	Martin Marietta Materials, Inc.
	Barnes Group, Inc.	Flowserve Corporation	Nordson Corporation
	Carpenter Technology Corporation	Gibraltar Industries, Inc.	Summit Materials, Inc.
	Chart Industries, Inc.	Graco Inc.	The Greenbriar Companies, Inc.
	Commercial Metals Company	Granite Construction Incorporated	Valmont Industries, Inc.
	Dycom Industries, Inc.	ITT Inc.	Vulcan Materials Company
	Eagle Materials, Inc.	Kirby Corporation	Watts Water Technologies, Inc.
	EnPro Industries, Inc.

The Peer Survey Data includes data from each company named in the Peer Group for base salary, target annual and long-term incentive compensation, and total target compensation obtained from the Radford Global Compensation Survey, as well as public filings.

In December 2022, the HR Committee reviewed benchmarking analyses for each NEO and other key executives based on the Peer Survey Data in developing 2023 total compensation consisting of base salaries, annual incentive compensation, and long-term incentive compensation. As a point of reference, when available for the NEOs, the Compensation Consultant also provided the HR Committee with the most recently available proxy disclosure data for the 2023 Peer Group.

Components of Compensation

In 2023, the three primary components of an executive's total target direct compensation were base salary, annual incentive compensation, and long-term incentive compensation, each as described below:

	COMPONENT		PURPOSE		DESIGN
FIXED					Reviewed at least annually to consider changes in responsibility, experience, individual performance, and market competitiveness.
	Base Salary	CASH		Attract, retain, and motivate key executives by providing market-competitive fixed compensation
AT-RISK					Market competitive targets and goals established for executives: •Specific financial metrics for Corporate and Group President Plans •Accountability for Execution of Strategic Initiatives No payouts when performance falls below financial thresholds and there has been a failure to execute strategic initiatives.
	Annual Incentive Compensation	CASH		Short-term at risk pay designed to motivate achievement of annual performance goals across the entire organization and within business units in support of our strategic priorities
					Our executives receive their LTI compensation in two parts: 1.60% of LTI in PBRSUs: Awards linked to achievement of Pre-Tax Return on Capital, Adjusted Cumulative Earnings per Share, and Total Shareholder Return relative to the performance of the S&P SmallCap 600 Index. Payouts in Arcosa Common Stock are made at end of a three-year performance period and can range from 0%-200% of target. No payouts if performance is below threshold. 2.40% of LTI in time-based restricted stock units ("TBRSU"): Awards vest three years ratable, 1/3 each, March 2024, 2025, and 2026.
	Long-Term Incentive Compensation	EQUITY		Long-term at risk pay designed to balance short-term at risk pay, enhance alignment between executives and shareholders, support our strategic priorities and long-term shareholder value creation

2023 Annual Target Total Compensation Mix

Consistent with our pay-for-performance philosophy, a significant portion of an executive’s total compensation opportunity (including that of each of the NEOs) is weighted toward performance-based pay and components we believe align with the interests of our shareholders. Our AIP and the PBRSUs component of the LTI award are considered performance-based pay because the payout of these awards is dependent on the achievement of specified performance goals. The remaining portion of the LTI award, the TBRSUs, while retentive in nature, also align with our performance as the final value realized is based on our share price.

For our CEO and our other NEOs, on average, the charts below show the percentage of 2023 target total direct compensation allocated to each compensation element as well as the amount of target compensation that is at risk. We consider compensation to be at risk if it is subject to achievement of performance goals and/or the value received is dependent on our stock price.

2023 Annual Compensation Determination

Individual base salaries and incentive targets for the NEOs and other key executives are established based on the breadth, complexity, and scope of their responsibilities, individual prior performance, experience, internal equity considerations, and market pay data.

In December 2022, the HR Committee, working with management and the Compensation Consultant, reviewed market compensation data, including the Peer Survey Data, to determine 2023 compensation for each of the NEOs and other key executives. The HR Committee reviewed and adjusted the NEOs’ 2023 base salaries and AIP and LTI award levels after consideration of the median of the Peer Group for their respective positions, performance, previous salary changes, experience, and other factors. The components of total target compensation for 2023 set forth below reflect our pay-for-performance philosophy.

BASE SALARY

The HR Committee establishes base salaries to attract, motivate, and retain key executives by providing a consistent level of pay that appropriately compensates each executive for the breadth, complexity, and scope of responsibility inherent in his or her position.

The following chart reflects the adjustments made to each NEO’s base salary for 2023:

Named Executive Officer	2022 Annual Base Salary Rate ($)	% Change		2023 Annual Base Salary Rate ($)

ANNUAL INCENTIVE COMPENSATION

The HR Committee selects performance metrics, performance goals, and other elements of annual incentive compensation with the objective of placing management’s focus on appropriate operational and financial objectives consistent with our annual operating plan. The HR Committee believes that there should be clear accountability for the performance of one’s business group. As a result, under our AIP, the group president NEOs are compensated primarily upon the results of their respective group of businesses, whereas the corporate NEOs are compensated primarily upon the results of the enterprise.

Under our AIP, the HR Committee may choose to, among other things, (i) modify or discontinue annual incentive compensation at any time; and (ii) increase or decrease an NEO’s annual incentive compensation on a discretionary basis; and will recoup excess compensation erroneously awarded consistent with our clawback policy if Arcosa restates its financial statements. The HR Committee may remove any unusual or infrequently occurring or non-recurring items of income or expense from the calculation of financial goal attainment and incentive compensation.

The HR Committee approved the following financial metrics and performance targets for the AIP for each of the NEOs to incentivize performance:

Corporate Plan (CEO, CFO, CLO)		Group President Plans (3 Group Presidents)
Performance Metric	Weighting	Performance Metric	Weighting
Enterprise Adjusted EBITDA	60%	Group Adjusted EBITDA	60%
Adjusted Corporate SE&A	20%	Group Adjusted EBITDA Margin	20%
Execution of Strategic Initiatives	20%	Execution of Strategic Initiatives	20%

2023 payouts are calculated from the actual performance of Arcosa, at the enterprise level and at the group level, with respect to measurement of the Adjusted EBITDA, Adjusted Corporate SE&A, and Group Adjusted EBITDA Margin. To evaluate management's performance against the established goals making up the Execution of Strategic Initiatives metric, the HR Committee considered the following non-exhaustive list of parameters:

ESG (including Safety)	Evaluation parameters to consider: •Progress on ARC-100 Safety Program driving positive and engaged culture of safety at all levels of the organization •Tracking ahead of our short-term Scope 1 and 2 GHG emissions intensity reduction goals •Social engagement, including community and corporate culture-focused efforts •Shareholder outreach and engagement
Growth	Evaluation parameters to consider: •Progress on redeploying proceeds from the Storage Tanks' divestiture •Success with bolt-on acquisitions •Advancement on large organic capital projects
Maintain Progress on Working Capital	Evaluation parameters to consider: •Minimizing working capital as a use of cash in 2023 •Continued focus on driving down days sales remain outstanding

(1) Calculation of the target level excludes the Adjusted EBITDA impact of the Wind Towers business.

(2) Execution of Strategic Initiatives is evaluated at the discretion of the HR Committee.

For the Adjusted EBITDA, Adjusted Corporate SE&A, and Group Adjusted EBITDA Margin components, performance at the target level resulted in 100% payout of the target award at the respective metric weighted percentage, performance below the minimum threshold level resulted in no payout, and performance above the maximum level was capped at a maximum total payout of 200% of the target award at the respective metric weighted percentage. The amount of incentive compensation earned with respect to these components was linearly interpolated for performance falling between the specified performance levels. With respect to the Execution of Strategic Initiatives component (with parameters discussed above), performance was evaluated holistically at the enterprise level at the discretion of the HR Committee. Performance at the target level resulted in 100% payout of the target award at the metric weighted percentage, and performance above the maximum level was capped at a maximum total payout of 200% of the target award at the metric weighted percentage. When combining each of the components of the AIP, actual payouts for 2023 could range from 0%-200% of the target.

In February 2024, the HR Committee evaluated the Company's performance and certified 2023 actual results in accordance with the predefined performance metrics and targets and the holistic evaluation of parameters for the Execution of Strategic Initiatives component under the AIP. Please see the "2023 Performance Highlights" section above for highlights of management's performance against these parameters considered in the payout of the 2023 AIP.

Based on our actual performance and the review of the Execution of Strategic Initiatives, the HR Committee approved the following 2023 award payouts for the NEOs:

2023 LONG-TERM INCENTIVE COMPENSATION

LTI compensation opportunities are a key part of the total target compensation for our NEOs. The LTI program objectives are to:

	Support a strong performance-based culture.		Align executives’ interests with those of shareholders.
	Attract and retain key leaders and other participants through the use of equity programs.		Maintain a well-defined line of sight between performance and award.

The NEOs' 2023 LTI awards consist of 60% PBRSUs for the performance period January 1, 2023 through December 31, 2025 and 40% TBRSUs. The 2023 LTI award opportunity details are as follows:

Performance-Based Restricted Stock Units. 60% of each NEO’s target 2023 LTI award opportunity is made in the form of PBRSUs, which will not vest unless the performance metric is met. The awarding of PBRSUs is designed to (i) increase the visibility of the long-term incentive performance goals for the program’s participants, (ii) align their efforts toward achieving these goals, and (iii) reinforce pay-for-performance philosophy through settlement of awards following the end of the relevant performance period. These units are non-voting and do not receive dividends or dividend equivalents during the performance period. The HR Committee approves performance targets and payout ranges at the beginning of the 3-year performance period. Our actual performance during the performance period determines the number of PBRSUs that will be ultimately earned following the end of the performance period. After the HR Committee certifies the actual results of the performance period, the earned PBRSUs are settled in shares of Common Stock upon the established vesting date.

The HR Committee approved the following company-wide performance metrics and weighting for the PBRSUs to incentivize long-term growth of shareholder value:

	Weighting of Total Performance-Based Equity Award
Average Pre-Tax Return on Capital	40%
Cumulative Adjusted Earnings per Share	40%
Relative Total Shareholder Return	20%

The awards will settle in March 2026 following determination of results of the 2023-2025 performance period. Each NEO may receive from 0% to 200% of the target PBRSUs based on actual performance against the target levels set by the HR Committee. The NEOs will earn 0% of the target value if the threshold performance level is not achieved. For performance falling between the specified levels, the amount of PBRSUs earned will be interpolated accordingly between the specified performance levels.

Time-Based Restricted Stock Units. 40% of the target 2023 LTI award opportunity was made in the form of TBRSUs to promote long-term executive retention and alignment with shareholders. The TBRSUs vest 33⅓% on each of March 15, 2024, 2025, and 2026 if the NEO remains continuously employed by Arcosa through such date. All TBRSUs are non-voting and provide for dividend equivalent units payable in cash, which will vest on the same schedule as the corresponding TBRSUs.

On May 9, 2023, the HR Committee, following consultation with the Compensation Consultant, approved one-time retention grants (the "Retention Grants") to Ms. Peck and Mr. Essl. The Retention Grants, each comprised of 21,985 TBRSUs with grant date values of $1,500,000, will vest over a four-year period beginning with 25% of the TBRSUs on May 15, 2025, 25% on May 15, 2026, and the remaining 50% on May 15, 2027. The HR Committee determined that retaining Ms. Peck and Mr.

  43

Executive Compensation Table of Contents

Essl, who are valuable members of the senior executive team and serve a critical role in executing the Company's business strategy, was in the Company's best interest. The HR Committee, working with the Compensation Consultant, designed the payout of the Retention Grants to motivate Ms. Peck and Mr. Essl to continue their considerable efforts in their roles in recognition of the competitive nature of the marketplace for the roles held by Ms. Peck and Mr. Essl.

The 2023 target LTI award opportunity for each NEO was set as a specified target dollar value as set forth below. The number of TBRSUs and PBRSUs awarded to the NEOs in March 2023 was calculated by dividing the target value for each NEO by our closing stock price on the grant date of March 2, 2023, which was $61.52 per share. The Retention Grants were not included in the Target Value of LTI Awards reflected below.

Named Executive Officer	Target Value of Time-Based Restricted Stock Units ($)	Target Value of Performance-Based Restricted Stock Units ($)	Total Target Value of LTI Award ($)
Antonio Carrillo	1,608,020	2,412,030	4,020,050
Gail M. Peck	336,000	504,000	840,000
Kerry S. Cole	251,000	376,500	627,500
Jesse E. Collins, Jr.	221,000	331,500	552,500
Reid S. Essl	288,400	432,600	721,000
Bryan P. Stevenson	204,600	306,900	511,500

2021-2023 PERFORMANCE-BASED RESTRICTED STOCK UNITS

In May 2021, each of the NEOs received an annual LTI award opportunity, which included a grant of 2021-2023 PBRSUs. The payout of these units is based on Arcosa’s Average Pre-Tax Return on Capital and Cumulative Adjusted Earnings Per Share ("Adjusted EPS") for the 2021-2023 performance period.

* See Annex A for a reconciliation of Non-GAAP measures to the most comparable GAAP measures.

In March 2024, the HR Committee approved the 2021-2023 performance period based on the Company's performance with such approval reflecting an update to the Adjusted EPS target levels to provide parity after the divestiture of the Storage Tanks business in 2022 and an exclusion of the impact of any AMP tax credits related to wind tower manufacturing in the calculation of the average return on capital and the adjusted EPS totals in the performance period. The 2021-2023 PBRSUs will settle upon vesting in May 2024, resulting in a payout of 168% of target as illustrated below.

The HR Committee believes these plans assist in recruiting and retaining senior executives and facilitate employment transition. Our retirement and savings compensation plans, as amended, consist of the following:

•Arcosa, Inc. 401(k) Plan (the "401(k) Plan") - a voluntary, tax qualified, defined contribution plan that covers most of Arcosa’s employees, including the NEOs and includes a dollar-for-dollar Company-matching contribution of up to six percent of the participant’s eligible pay for each payroll period, consistent with market terms.

•Arcosa, Inc. Deferred Compensation Plan (the "Deferred Compensation Plan") - a plan for highly compensated employees, including the NEOs, allowing them to defer a portion of their base pay and annual incentive in accordance with the Deferred Compensation Plan.

CHANGE IN CONTROL SEVERANCE PLAN

Arcosa’s Board continues to believe it is appropriate to reinforce and encourage the attention and dedication of members of Arcosa’s senior management to the interests of shareholders without distraction in potential circumstances arising from the possibility of a change in control of Arcosa.

On March 3, 2022, our Board approved the 2022 CIC Plan. Each of the NEOs entered into a participation agreement under the 2022 CIC Plan upon which such officer became subject to the 2022 CIC Plan and any prior individual change in control agreements were terminated. The 2022 CIC Plan has a three-year term that automatically renews with one-year extensions unless notice of termination is otherwise provided.

The 2022 CIC Plan contains a "double trigger" provision that requires both a change in control of Arcosa and a qualifying termination of the NEO’s employment before compensation will be paid under the 2022 CIC Plan or for acceleration of equity awards that are granted after December 6, 2018. Pursuant to the 2022 CIC Plan, if an NEO’s employment is terminated by Arcosa without "Cause" or by the participant for "Good Reason," in each case, within six months prior to and in connection with a "Change in Control" or within two years following a "Change in Control" (each, as defined in the 2022 CIC Plan), then:

•the NEO will receive a lump-sum cash severance payment equal to (i)(x) the sum of the NEO’s annual base salary and target annual incentive bonus, or, if higher and the Change in Control or date of termination occurs more than six months into a fiscal year, the annual incentive bonus payable on actual performance multiplied by (y) three for the Chief Executive Officer, two for the Chief Financial Officer, the Chief Legal Officer, and group presidents, and one and a half for all other participants; plus (ii) a prorated annual incentive bonus for the year in which the termination occurs based on target performance;

•all then-outstanding and unvested equity awards that were granted on or after December 6, 2018 will become 100% vested;

•all benefits under any then-outstanding deferred compensation arrangements will become 100% vested; and

  45

Executive Compensation Table of Contents

•for 24 months following the NEO’s termination, (i) the NEO will continue to receive medical, dental, vision, health, and life insurance benefits no less favorable than were provided prior to termination, provided that such coverage will cease if the NEO obtains comparable coverage under a subsequent employer’s benefit plan; and (ii) the NEO will receive executive level outplacement services, up to a maximum of $15,000.

The NEOs are required to execute a release in favor of Arcosa in exchange for receiving 2022 CIC Plan benefits. Each NEO is subject to non-competition, non-solicitation, and non-recruitment covenants for 12 months following termination of employment, as well as confidentiality obligations and non-disparagement covenants that survive indefinitely.

The 2022 CIC Plan does not include excise tax gross ups. In the event payments under the 2022 CIC Plan would trigger the "golden parachute" excise tax under Sections 280G and 4999 of the Code, such payments will be reduced if such reduction would result in a greater after-tax benefit to the NEO.

Arcosa considers the compensation payable under the 2022 CIC Plan upon specified events of termination following a Change in Control to be appropriate in light of the unique mix of the industries in which it is engaged, the limited number of companies in many of those industries, and the uncertain length of time necessary to find new employment. The level of payments and benefits provided under the 2022 CIC Plan are considered appropriate. These benefits are recognized as part of the total compensation package and are reviewed periodically but may not be specifically considered by the HR Committee when making changes in base salary, annual incentive compensation, or long-term incentive compensation.

The Change in Control severance benefits are discussed in the Compensation of Executives section under "Potential Payments Upon Termination or Change in Control." Arcosa does not have severance agreements with NEOs other than in connection with the 2022 CIC Plan.

HEALTH AND WELFARE BENEFITS

The Arcosa-supported medical plan, life insurance, long-term disability plan, employee-paid dental, vision, critical illness insurance, and supplemental life insurance are substantially similar for the NEOs as for all full-time employees. Arcosa does not provide health benefits to retirees.

Tax and Accounting Implications of Executive Compensation

Section 162(m) of the Code limits the federal income tax deduction for public corporations to $1.0 million per year for compensation paid in any fiscal year to the NEOs. The HR Committee will establish executive compensation arrangements that it believes are in the best interests of Arcosa and our shareholders, even if those arrangements are not fully deductible under Section 162(m).

Arcosa recognizes the compensation expense for all equity awards made to employees and directors, including stock options, stock appreciation rights and other awards, in our financial statements based on the principles of ASC Topic 718.

DEFINITION OF NON-GAAP AND OTHER PERFORMANCE MEASURES USED IN THE CD&A

The following sets forth the definitions of the non-GAAP and other performance measures that were approved by the HR Committee in establishing performance levels under our incentive plans. In determining final awards, the HR Committee retains the discretion to make adjustments for incentive plan purposes to eliminate the impact (positive or negative) of items that the HR Committee deems are appropriate:

•Adjusted Corporate SE&A: non-production costs recorded in selling, general, and administrative expense on the Company’s externally reported financial statements including, but not limited to, corporate department payroll costs; external legal, accounting, audit, IT; public company reporting and compliance costs and before material restructuring/reorganization expenses, acquisition, or divestiture-related gains/losses or expenses (including transaction expenses and purchase price accounting adjustments), expenses to comply with COVID-related or other compliance policies or regulations, the impact of changes in accounting rules all measured as a percentage of Enterprise Revenue in each case as approved by the HR Committee and any other adjustments the HR Committee deems appropriate.

•Cumulative Adjusted Earnings Per Share: the sum of the Adjusted Earnings Per Share for each year in the three-year performance period.

•Enterprise Adjusted EBITDA: enterprise operating income (loss) from continuing operations before interest, income taxes, depreciation, depletion, and amortization, extraordinary adjustments to asset values (gains or losses), asset impairment charges, material restructuring/reorganization expenses, gains or losses on extraordinary dispositions, gains or losses from currency translation adjustments, acquisition or divestiture-related gains/losses or expenses (including transaction expenses and purchase price accounting adjustments), expenses to comply with COVID-related policies or regulations, the impact of changes in accounting rules, any changes to federal, state, or local tax laws that impact the Company's tax liability, in each case as approved by the HR Committee, and any other adjustments the HR Committee deems appropriate.

•Execution of Strategic Initiatives: measured holistically by progress in ESG initiatives including safety, growth in the businesses, and execution of working capital management.

•Group Adjusted EBITDA Margin: Group Adjusted EBITDA divided by Group Revenues.

•Pre-Tax Return on Capital: Enterprise Adjusted EBITDA (as defined above) Divided by ((Current Assets – Current Liabilities + Current Portion of Long-Term Debt) + Net Plant, Property and Equipment). Balance Sheet items will be calculated using an average of 5 points (Beginning of Q1, End of Q1, End of Q2, End of Q3, and End of Q4).

•Total Shareholder Return: the annualized percent change in value from the beginning of the performance period to the end and including the reinvestment of dividends. A calendar-month average stock price measured at the beginning and the end of the performance period will be used.

(1) The grant date of all stock awards is the date of the HR Committee meeting or Board meeting at which such award was approved.

(2) Represents the potential amounts payable under the 2023 AIP for attainment of specified performance goals. Actual amounts earned were paid in March 2024 and are disclosed in the 2023 Summary Compensation Table. Threshold, target, and maximum amounts each assume that the performance level was met for all applicable financial metrics. Performance below the minimum threshold results in no payout, and performance above the maximum level is capped at a maximum total payout of 200% of the target award. For performance falling between the specified levels, the amount earned will be interpolated accordingly. The performance metrics and targets used to determine the amounts of the awards paid are described above under "Compensation Discussion and Analysis."

(3) Represents the potential number of PBRSUs of Arcosa that could be earned based on financial performance for 2023 through 2025. Actual amounts of PBRSUs will vest and settle in shares of Common Stock on March 15, 2026, based on attainment of performance goals. Awards will pay out between 0% to 200% of the target PBRSU based on actual performance against the performance levels set by the HR Committee. For performance falling between the

specified levels, the amount of PBRSUs earned will be interpolated accordingly. The performance metrics and targets used to determine the amounts of the awards paid are described above under "Compensation Discussion and Analysis."

(4) Represents TBRSUs of Arcosa, of which 33 1/3% will vest on each of March 15, 2024, 2025, and 2026 (except with respect to the one-time retention award with a grant date of May 9, 2023 for Mr. Essl and Ms. Peck, which will vest over four years with 25% on May 15, 2025, 25% on May 15, 2026, and the remaining 50% on May 15, 2027, if the NEO remains an employee on such date). TBRSUs accrue dividend equivalent units payable in cash, which vest on the same vesting schedule as the underlying award.

(5) The grant date fair value of the stock awards is calculated in accordance with ASC Topic 718.

DISCUSSION REGARDING SUMMARY COMPENSATION TABLE AND GRANTS OF PLAN-BASED AWARDS

In 2023, the NEOs were granted 40% of their respective target LTI compensation opportunity as TBRSUs. These awards were granted to reflect the HR Committee’s desire to incentivize the long-term commitment of key executives to build shareholder value. These TBRSUs vest over three years with 33 1/3% on each of March 15, 2024, 2025, and 2026, if the NEO remains an employee on such date. All TBRSUs are non-voting and provide for dividend equivalent units payable in cash, which will vest on the same schedule as the corresponding TBRSUs.

The remaining 60% of the NEO's target LTI compensation opportunity was granted in the form of PBRSUs for the 2023-2025 performance period based on three-year average Pre-Tax Return on Capital, Cumulative Adjusted Earnings Per Share, and Total Shareholder Return relative to the S&P SmallCap 600 Index. Each PBRSU earned will convert into either one share of Common Stock or the cash value of one share of Common Stock and vest on March 15, 2026. During the vesting period, recipients do not earn dividends on, and are not entitled to vote with respect to, the PBRSUs.

See "2023 Annual Compensation Determination—2023 Long-Term Incentive Compensation" under "Compensation Discussion and Analysis" above for a description of the terms of 2023 LTI compensation.

In the "Grants of Plan-Based Awards" table, the estimates for future payouts under the 2023 AIP awards represent potential payments of annual incentive compensation for 2023 based on achievement of specified performance metrics. See "2023 Annual Compensation Determination—Annual Incentive Compensation" under "Compensation Discussion and Analysis" above for a description of the 2023 AIP awards.

We have a 401(k) plan that permits employees to elect to set aside a portion of their compensation (subject to the maximum limit on the amount of compensation permitted by the Code to be deferred for this purpose) in a trust to pay future retirement benefits. For 2023, we matched up to six percent of the employee’s eligible compensation set aside for this purpose with the cumulative amount of our match capped at $19,800. See "Compensation Discussion and Analysis—Other Compensation Plans—Post-Employment Benefits."

OUTSTANDING EQUITY AWARDS AT YEAR-END

The following table summarizes as of December 31, 2023, for each NEO, the number of shares of unvested stock awards held in both Arcosa and Former Parent. The market value of the stock awards was based on the closing price of the Common Stock as of December 29, 2023 (the last trading day of the year), which was $82.64 for Arcosa (stock ticker "ACA") and $26.59 for our Former Parent (stock ticker "TRN").

Actual amounts of PBRSUs will vest and settle in shares of Common Stock on March 15, 2026 based on Arcosa's Average Pre-Tax Return on Capital, Cumulative Adjusted Earnings Per Share, and Total Shareholder Return relative to the S&P SmallCap 600 Index for the performance period. Awards will pay out between 0% to 200% of the target PBRSU based on actual performance against the performance levels set by the HR Committee. For performance falling between the specified levels, the amount of PBRSUs earned will be interpolated accordingly. See "Compensation Discussion and Analysis—2023 Annual Compensation Determination—2023 Long-Term Incentive Compensation."

(2) Represents earnings or losses in the Deferred Compensation Plan for Messrs. Cole and Essl, and Ms. Peck. For Mr. Carrillo, this column represents earnings in respect of deferred director fees previously earned as a director of our Former Parent.

(3) Includes salary and incentive compensation deferrals to, and Company matching amounts under, the Deferred Compensation Plan in the aggregate that are reported in the Summary Compensation Table for Mr. Essl, $62,450 in 2022 and $54,676 in 2021.

DEFERRED COMPENSATION DISCUSSION

For 2023, we had a deferred compensation plan for highly compensated employees who are limited as to the amount of deferrals allowed under our 401(k) Plan. Participants may elect to defer salary prior to the beginning of the fiscal year and annual incentive pay prior to the beginning of the year to which the incentive payments related. Participants chose from several mutual fund-like deemed investments. See "Compensation Discussion and Analysis—Other Compensation Plans."

Amounts are paid out immediately upon death. Upon termination of employment, amounts in the Deferred Compensation Plan are paid out beginning six months after termination of employment in lump sum or annual installments from one to twenty years according to election of the participant.

Potential Payments Upon Termination or Change in Control

DEATH, DISABILITY, OR RETIREMENT

Arcosa’s long-term disability plan provides all salaried employees, including the NEOs, with a disability benefit after six months of disability of 60% of base salary up to a maximum of $15,000 a month while disabled and until normal retirement at age 65, provided that the disability occurred prior to age 60. If the disability occurred at age 60 or older, the maximum benefit period will be based on the age at disability. Deferred compensation benefits that are payable upon termination are described under "Deferred Compensation Discussion."

Equity awards held by the NEOs have no acceleration of vesting upon voluntary or involuntary termination, but vesting is accelerated on death or disability, and in some cases retirement. The Company AIP provides that in the event of death or disability, if the HR Committee so determines, the participant will be eligible to receive the pro rata portion of the participant’s AIP that would have been payable in such year. The Company AIP also provides that in the event of termination of employment for any other reason following the end of the performance period and prior to the date of actual payment, the HR Committee may pay the participant an amount not to exceed the amount earned.

The following table provides the dollar value of (i) accelerated vesting of equity awards, and (ii) the payment of annual incentive compensation, in each case assuming each of the NEOs had been terminated by death, disability, or retirement on December 31, 2023. As of December 31, 2023, there were no outstanding stock options held by any of the NEOs.

CHANGE IN CONTROL

Each of the NEOs is currently a participant in the 2022 CIC Plan. For additional discussion of the 2022 CIC Plan, see "Compensation Discussion & Analysis - Other Compensation Plans - Change in Control Severance Plan." Pursuant to the terms of the 2022 CIC Plan, if the NEO’s employment was terminated by Arcosa without "Cause" (as defined below) or by the participant for "Good Reason" (as defined below), in each case, within six months prior to and in connection with or within two years following a "Change in Control" (as defined below), then equity awards granted on or after December 16, 2018 vest and benefits under the Deferred Compensation Plan and 401(k) Plan vest. In addition, the NEO would have received a lump-sum cash severance payment equal to (i)(x) the sum of the NEO’s annual base salary and target annual incentive bonus, or, if higher and the Change in Control or date of termination occurs more than six months into a fiscal year, the annual incentive bonus payable on actual performance multiplied by (y) three for the CEO, two for the CFO, the CLO, and group presidents, and one and a half for all other participants; plus (ii) a prorated annual incentive bonus for the year in which the termination occurs based on target performance and the NEO would have received continued insurance benefits for 24 months following termination and outplacement services up to a maximum of $15,000.

"Cause" is generally defined as a participant’s (i) continued failure to satisfactorily perform his or her duties with Arcosa, failure to comply with Arcosa’s Code of Conduct and other written policies, willful failure to follow directions of the Board or his or her supervisor or manager, or any other willful act that likely will result in a materially negative effect to Arcosa, which, if curable, is not cured within thirty (30) days after notice thereof; (ii) fraud, theft, misappropriation embezzlement, dishonesty, or breach of fiduciary duty by the Participant; (iii) misappropriation of any corporate opportunity or otherwise obtaining personal profit from any transaction which is adverse to the interests of Arcosa or to the benefits of which Arcosa is entitled; (iv) the conviction of a crime that has caused or may be reasonably expected to cause material injury to Arcosa or any of its affiliates, or the conviction of a felony; or (v) willful misconduct which is injurious to Arcosa (monetarily or otherwise), which if curable, is not cured by the participant within thirty (30) days after of a written notice from Arcosa.

  55

Executive Compensation Table of Contents

"Change in Control" is generally defined as (i) any other person or entity acquires beneficial ownership of 30% or more of Arcosa’s outstanding Common Stock, or the combined voting power over Arcosa’s outstanding voting securities unless the transaction resulting in the person becoming the beneficial owner of 30% or more of the combined voting power is approved in advance by Arcosa’s Board; (ii) incumbent directors cease for any reason to constitute at least a majority of the Board; (iii) a merger or consolidation of Arcosa or any of its subsidiaries with any other corporation, or an agreement for the sale or disposition by Arcosa of all or substantially all of Arcosa’s assets, subject to certain exceptions; or (iv) the stockholders approve a complete liquidation or dissolution of Arcosa.

"Good Reason" is generally defined as (i) a material diminution in the participant’s job title, responsibilities or duties; (ii) after the occurrence of a Change in Control, a material adverse change in the nature or scope of the authorities, powers, functions, responsibilities, or duties attached to the position(s) with Arcosa that the participant held immediately before the Change in Control; (iii) a reduction by Arcosa in the participant’s base salary, unless the reduction is a proportionate reduction of the compensation of the participant and all other senior officers of Arcosa as a part of a company-wide effort to enhance Arcosa’s financial condition; (iv) any action by Arcosa which would materially reduce the participant’s benefits, in the aggregate, under Arcosa’s benefit plans and incentive plans; (v) a change of more than fifty (50) miles from the location where the participant performs the majority of the participant’s job duties immediately prior to the Change in Control; or (vi) any material breach by Arcosa of any provision of the 2022 CIC Plan. The participant is required to provide Arcosa with an opportunity to remedy the Good Reason event prior to the participant submitting a notice of termination for Good Reason.

The following table provides the payments and benefits reflecting a Change in Control occurring on December 31, 2023, with each NEO's employment being terminated by Arcosa without Cause or for Good Reason on such date:

Name	Equity Awards ($)(1)	AIP ($)(2)	Cash Compensation ($)(3)	Continuation of Benefits ($)(4)	Total ($)

(1) Accelerated vesting of equity awards. The market value of the outstanding ACA and TRN equity awards was based on the closing price of the Common Stock as of December 29, 2023 (the last trading day of the year), which was $82.64 for Arcosa and $26.59 for our Former Parent.

(2) Payment of 2023 award under the AIP at target performance.

(3) Cash lump sum equal to the sum of base salary and AIP at greater of performance or target both then in effect, multiplied by (i) three for the CEO, (ii) two for the CFO, the CLO, and group presidents, and (iii) one and a half for all other participants.

(4) Estimated cost of continuation for 24 months of medical, life, and other insurance benefits, and the maximum amount of outplacement services benefits.

(5) In addition to the amounts reflected in the table, Mr. Carrillo would also receive a cash payout for his cash balance under the Director Deferred Plan (as defined below), which represents fees earned and deferred while he served as a non-employee director of Former Parent. As of December 31, 2023, his accumulated cash balance in the Director Deferred Plan was $455,263.

CEO Pay Ratio

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of SEC Regulation S-K, Arcosa is providing the following information about the relationship of the median of the annual total compensation of its employees and the annual total compensation of Mr. Carrillo, the CEO.

	2023 Compensation
CEO, Antonio Carrillo	$6,474,120
Median Employee	$66,843
Compensation Ratio	97:1

SEC rules and regulations require a company to identify the median employee only once every three years, absent significant changes to the company's employee population, employee compensation arrangements or median employee's status during that period that would reasonably be expected to result in a significant change in the pay ratio. For 2023, we concluded that there have been no significant changes in our employee population or employee compensation arrangements that we reasonably believe would significantly impact our pay ratio disclosure, thus the selection of the median employee remained unchanged from 2022.

Arcosa calculated the median employee's total annual compensation in the same manner as we calculated the CEO's total annual compensation in the Summary Compensation Table.

The ratio disclosed above is a reasonable estimate calculated in a manner consistent with Item 402(u) of SEC Regulation S-K.

  57

Pay Versus Performance

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of SEC Regulation S-K, Arcosa is providing the information below, including a table disclosing specified executive compensation and financial performance measures for the three most recently completed fiscal years.

(1) Mr. Carrillo is the PEO, the principal executive officer, reflected in the columns above.

(2) The non-PEO named executive officers ("Non-PEO NEOs") reflected in the columns above represent Messrs. Beasley, Cole, Collins, Essl, and Stevenson for 2020; Messrs. Beasley, Cole, Collins, Essl, and Stevenson, and Ms. Peck for 2021; and Messrs. Cole, Collins, Essl, and Stevenson, and Ms. Peck for 2022 and 2023.

(3) To better align with recent SEC guidance, for 2023 we changed the peer group used for purposes of the pay-versus-performance disclosure from the S&P Small Cap 600 Index (the "Old Peer Group") to the S&P Small Cap 600 Construction & Engineering Industry Index (the "Peer Group"). For the Old Peer Group, the total shareholder return for fiscal years 2020, 2021, 2022 and 2023 would be $111, $141, $118, and $137 respectively.

(4) 2022 Adjusted Net Income is $106.8M, which is adjusted for the gain on the sale of the Storage Tanks business, net of taxes, and impact of acquisition and divestiture related expenses, net of taxes.

Most Important Measures to Determine 2023 Compensation Actually Paid

We selected the following measures as the most important financial performance measures used by us to link compensation actually paid to Arcosa's performance. We identified Adjusted EBITDA as the "company selected measure," which represents the single most important financial measure. For additional discussion on these measures and how they factor into our named executive officers' compensation in 2023, please see the discussion in our "Compensation Discussion and Analysis" in the "Annual Incentive Compensation" and "2023 Long-Term Incentive Compensation" sections.

Relationship Between CAP and Financial Measures

The following charts provide a graphical depiction of the relationship between the CAP and the selected financial measures in addition to the relationship between Arcosa and the Peer Group's TSR. The 2020 CAP for both the PEO and the Non-PEO NEOs in each of the charts reflect a significant increase in stock price year over year and an increase in the estimated performance of outstanding PBRSUs in 2020. The 2020 CAP to PEO also includes the increase in value of the one-time equity grant made to Mr. Carrillo when he became CEO in 2018. The 2021 CAP to Non-PEO NEOs reflects the forfeiture of Mr. Beasley’s 2021 stock award, causing a decrease in the average CAP for the Non-PEO NEOs for 2021. The 2023 CAP for both the PEO and the Non-PEO NEOs in each of the charts reflects an increase in stock price of greater than 50% and an increase in the estimated performance of outstanding PBRSUs in 2023. The 2023 average CAP to Non-PEO NEOs also includes the increase in value of the one-time retention equity grant made to Mr. Essl and Ms. Peck.

Director Compensation

In December 2022, the G&S Committee conducted its annual review, pursuant to the G&S Committee Charter, of non-employee director compensation. Following a review of comparative market analysis provided by the Compensation Consultant, the G&S Committee determined no changes were necessary for non-employee director compensation for 2023 except for an increase in the Non-Executive Chair Retainer Fee.

The components of 2023 compensation for our non-employee directors, as approved by the Board, are as follows:

Additional Annual Director Compensation
	$120,000	Non-Executive Chair Retainer Fee(2)
	$20,000	Audit Committee Chair Retainer Fee
	$20,000	Human Resources Committee Chair Retainer Fee
	$15,000	Governance & Sustainability Committee Chair Retainer Fee
	$2,000	Board and Committee Additional Meeting Fee per meeting attended(3)
	$2,000	Ad hoc or special assignment work performed for or at the request of the CEO, per diem

(1) Number of shares is based on the closing stock price on the date of award. The annual equity award is granted following the Annual Meeting for continuing directors in the form of restricted stock with one-year cliff vesting or deferred restricted stock units that vest in one year but remain deferred until a qualifying termination of service from the Board, with the decision being made at the election of the individual director. Following the director's qualifying termination of services, vested deferred restricted stock units convert into shares of Common Stock equal to the number of units.

(2) The Non-Executive Chair Retainer Fee may be paid, at the Chair's election, in the form of cash or deferred restricted stock units. The Non-Executive Chair Retainer Fee was increased in 2023 to $120,000 from $100,000.

(3) The Additional Meeting Fee is payable to members of the Board or members of Board committees for their attendance of each meeting attended, beginning with the second non-regularly scheduled meeting of the Board or its committees.

Non-employee directors may elect, pursuant to the Arcosa, Inc. Deferred Plan for Director Fees (the "Director Deferred Plan"), to defer the receipt of all or a specified portion of the cash retainers and fees to be paid to him or her. Deferred amounts are credited to an account on the books of Arcosa and treated as if invested either at an interest rate equivalent (5% in 2023) or, at the director’s prior election, in units ("phantom stock units") of the Common Stock at the closing price on the NYSE on the last day of the quarter following the date that a payment is credited to the director’s account. The phantom stock units are settled only in cash. Phantom stock units are credited with amounts equivalent to dividends paid on the Common Stock. Upon a qualifying termination, the value of the Director Deferred Plan account will be paid in cash to the director in a lump sum or in annual installments not exceeding ten years according to the director’s prior election.

Fees deferred pursuant to the Director Deferred Plan are credited to the director’s Director Deferred Plan account monthly. Fees that are not deferred pursuant to the Director Deferred Plan are paid in cash quarterly, in arrears.

Messrs. Carrillo and Gafford participated in our Former Parent's deferred plan for director fees. In connection with the Separation, amounts accumulated under this plan were transferred to Arcosa's Director Deferred Plan and continue to be deferred until a qualifying termination under the Director Deferred Plan.

62

Table of Contents Director Compensation

To further align our non-employee directors’ and shareholders’ interests, we require that the directors hold shares of our Common Stock in an amount equal to five times the annual Board cash retainer within five years of becoming a director. All of our directors have met or are on track to meet the ownership requirements.

Non-employee directors may also participate in Arcosa's matching gifts program on similar terms as our employees. Under the program, Arcosa matches contributions up to $5,000 per year, per director, to charitable organizations.

The following table summarizes the compensation paid by Arcosa to non-employee directors for the fiscal year ended December 31, 2023. Mr. Carrillo does not receive additional compensation for his services as a director of Arcosa.

Proposal Three Ratification of the Appointment of Ernst & Young LLP
Ernst & Young LLP	The Audit Committee has appointed Ernst & Young as the independent registered public accounting firm of Arcosa for the year ending December 31, 2024. Although the Amended and Restated Bylaws do not require that we seek shareholder ratification of the appointment of Ernst & Young as our independent registered public accounting firm, we are doing so as a matter of good corporate governance. If the shareholders do not ratify the appointment, the Audit Committee will reconsider whether or not to retain Ernst & Young. Even if the appointment is ratified, the Audit Committee in its discretion may change the appointment at any time during the year if it determines that a change would be in the best interests of Arcosa and its shareholders.
	Arcosa has been advised by Ernst & Young that the firm has no relationship with Arcosa or its subsidiaries other than that arising from the firm’s engagement as auditors, tax advisors, and consultants. Arcosa has also been advised that representatives of Ernst & Young will be present at the Annual Meeting where they will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.
	"FOR" The Board of Directors recommends that you vote FOR ratification of the appointment of Ernst & Young as the Company’s independent registered public accounting firm for the year ending December 31, 2024.

Report of the Audit Committee

We are a standing committee comprised of independent directors as "independence" is currently defined by SEC regulations and the applicable listing standards of the NYSE. The Board of Directors has determined that each of the members of the Audit Committee are "audit committee financial experts" as defined by applicable SEC rules. We operate under a written charter adopted by the Board of Directors. A copy of the charter is available on our website at ir.arcosa.com under the heading "Corporate Governance — Board Committees & Charters— Arcosa Audit Committee Charter."

We annually select Arcosa’s independent auditors. That recommendation is subject to ratification by Arcosa’s shareholders.

Management is responsible for Arcosa’s financial statements, internal controls, and the financial reporting process. The independent auditors are responsible for performing an independent audit of Arcosa’s consolidated and combined financial statements in accordance with auditing standards generally accepted in the United States of America and issuing a report thereon. As provided in our charter, our responsibilities include the monitoring and oversight of these processes.

Consistent with our charter responsibilities, we met and held discussions with management and the independent auditors. In this context, management and the independent auditors represented to us that Arcosa’s consolidated and combined financial statements for the fiscal year ended December 31, 2023 were prepared in accordance with U.S. Generally Accepted Accounting Principles. We reviewed and discussed the consolidated and combined financial statements with management and the independent auditors and discussed with the independent auditors matters required to be discussed by Auditing Standard No. 1301, "Communications with Audit Committees," issued by the Public Company Accounting Oversight Board ("PCAOB").

Arcosa’s independent auditors have also provided to us the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent auditors’ communications with the Audit Committee, and we discussed with the independent auditors that firm’s independence. We also considered whether the provision of non-audit services is compatible with maintaining the independent auditors’ independence and concluded that such services have not impaired the auditors’ independence.

Based upon our reviews and discussions with management, Arcosa's internal auditors, and the independent auditors, and our review of the representation of management and the report of the independent auditors to the Audit Committee, we recommended to the Board of Directors that the audited consolidated and combined financial statements be included in Arcosa’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC.

Additional Information

Shareholder Proposals for the 2025 Proxy Statement

Shareholder proposals to be presented at the 2025 Annual Meeting of Shareholders, for inclusion in Arcosa’s Proxy Statement and form of proxy relating to the meeting pursuant to SEC Rule 14a-8, must be received by Arcosa at its offices in Dallas, Texas, addressed to the Corporate Secretary of Arcosa, no later than November 27, 2024. Upon timely receipt of any such proposal, Arcosa will determine whether or not to include such proposal in the Proxy Statement and form of proxy in accordance with applicable regulations and provisions governing the solicitation of proxies. In addition, shareholders who intend to solicit proxies in support of director nominees other than Arcosa’s nominees must comply with the requirements of SEC Rule 14a-19.

Director Nominations or Other Business for Presentation at the 2025 Annual Meeting

Our Amended and Restated Bylaws establish advance notice procedures with regard to director nominations and shareholder proposals that are not submitted for inclusion in Arcosa's Proxy Statement, but that a shareholder instead wishes to present directly at an annual meeting. These procedures provide, generally, that shareholders desiring to place in nomination persons for directors and/or bring a proper subject of business before an annual meeting must do so by a written notice timely received (on or before February 8, 2025, but no earlier than January 9, 2025, for the 2025 Annual Meeting of Shareholders) to the Corporate Secretary of Arcosa. Shareholders should review the specific procedures set forth in the Amended and Restated Bylaws and SEC Rule 14a-19 regarding the exact information required. Copies of the Amended and Restated Bylaws are available from the Corporate Secretary at Arcosa, 500 N. Akard St., Suite 400, Dallas, TX 75201.

Questions and Answers About the Meeting

Voting and Questions During the Annual Meeting of Shareholders

Shareholders may vote their shares electronically online during the Annual Meeting of Shareholders.

If you choose to vote your shares online during the meeting, please follow the instructions posted at www.virtualshareholdermeeting.com/ACA2024. You will need the 16-digit control number included on your Proxy Card or voting instruction form. Voting electronically online during the Annual Meeting will replace any previous votes. Shareholders may submit pertinent questions prior to or during the meeting, and questions will be answered during the meeting, subject to time constraints. For more information on how to submit pertinent questions, please follow the instructions posted at www.virtualshareholdermeeting.com/ACA2024.

Whether or not you plan to attend the virtual meeting, we encourage you to vote by proxy as soon as possible. Your shares will be voted in accordance with your instructions.

Who is entitled to vote and how many votes do I have?

The outstanding voting securities of Arcosa consist of shares of Common Stock, $0.01 par value per share. The record date for the determination of the shareholders entitled to notice of and to vote at the Annual Meeting, or any postponement or adjournment thereof, has been established by the Board of Directors as the close of business on March 14, 2024. At that date, 48,561,836 shares of Common Stock were outstanding and entitled to be voted. A holder of Common Stock will be entitled to one vote per share on each matter properly brought before the Annual Meeting.

Why did I receive a Notice of Internet Availability of Proxy Materials?

In order to both save money and protect the environment, we have elected to provide access to our proxy materials and Annual Report to Shareholders for the fiscal year ended December 31, 2023 ("2023 Annual Report") on the Internet, instead of mailing the full set of printed proxy materials, in accordance with the rules of the SEC for the electronic distribution of proxy materials. Proxy materials or a Notice of Internet Availability of Proxy Materials (the "Notice") are being first released or mailed to shareholders on or about March 26, 2024. If you received a Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you request it. Instead, the Notice instructs you on how to obtain and review all of the important information contained in the Proxy Statement and Annual Report. The Notice also instructs you on how to submit your proxy over the Internet. If you received a Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials included in the Notice.

What is the difference between holding shares as a shareholder of record and as a beneficial owner of shares?

Shareholder of Record or Registered Shareholder. If your shares of Common Stock are registered directly in your name with our transfer agent, you are considered a "shareholder of record" or a "registered shareholder" of those shares.

Beneficial Owner of Shares. If your shares are held in an account at a bank, brokerage firm, or other similar organization, then you are a beneficial owner of shares held in "street name." In that case, you will have received these proxy materials from the bank, brokerage firm, or other similar organization holding your account and, as a beneficial owner, you have the right to direct your bank, brokerage firm, or similar organization as to how to vote the shares held in your account.

How do I vote if I am a shareholder of record?

In Advance by Telephone or Internet. All shareholders of record can vote by telephone using the toll-free telephone number on the Notice or Proxy Card, via the Internet at www.proxyvote.com, or via smart phone using the QR code on your Notice or

70

Table of Contents Questions and Answers

Proxy Card, and using the procedures and instructions described on the Notice or Proxy Card. You will need the 16-digit control number provided in your proxy materials.

In Advance by Written Proxy. If you are a shareholder of record and receive a Notice card, you may request a written Proxy Card by following the instructions included in the Notice.

Virtually During the Meeting. All shareholders of record may vote by attending the meeting virtually at www.virtualshareholdermeeting.com/ACA2024.

Whether or not you plan to attend the meeting, we encourage you to vote by proxy as soon as possible. Your shares will be voted in accordance with your instructions.

How do I vote if I am a beneficial owner of shares?

As the beneficial owner, you have the right to direct your broker on how to vote the shares in your account. Your broker should give you instructions for voting your shares by Internet, telephone, mail, or smart phone. As a beneficial owner, you are invited to virtually attend the Annual Meeting, but you may not vote your shares at the Annual Meeting unless you request and obtain a valid legal proxy from your broker giving you the legal right to vote the shares virtually during the Annual Meeting.

Who will vote my shares during the Annual Meeting and how will they vote my shares if I provide voting instructions and/or grant my proxy?

The persons named as proxies in the Proxy Card or electronic voting form will vote your shares according to your instructions. If you sign and return your Proxy Card but do not make any of the selections, the named proxies will vote your shares: (i) FOR election of the director nominees as set forth in this Proxy Statement; (ii) FOR approval, on an advisory basis, of the compensation of Arcosa’s named executive officers as disclosed in these materials; and (iii) FOR ratification of Ernst & Young as the independent registered public accounting firm of Arcosa for the year ending December 31, 2024.

What is a Broker Non-Vote?

A "broker non-vote" occurs when a broker submits a proxy for the meeting with respect to a discretionary, or routine, matter but does not have the authority to vote on non-discretionary matters because the beneficial owner did not provide voting instructions on those matters.

Under NYSE rules, the proposal to ratify the appointment of Ernst & Young as the independent registered public accounting firm for the year ending December 31, 2024 (Proposal 3) is considered a "discretionary" or "routine" item. This means that brokerage firms may vote in their discretion on behalf of clients (beneficial owners) who have not furnished voting instructions. In contrast, all of the other proposals set forth in this Proxy Statement are "non-discretionary" or "non-routine" items—brokerage firms that have not received voting instructions from their clients on these matters may not vote on these proposals.

Can I change or revoke my vote?

If you are a registered shareholder, any subsequent vote you cast will replace your earlier vote. This applies whether you cast your vote by executing a Proxy Card bearing a later date, vote by telephone, Internet, or smart phone, or by virtually attending the Annual Meeting and submitting your vote virtually during the Annual Meeting. The proxy may be revoked at any time before it is exercised by filing with Arcosa a written revocation addressed to the Corporate Secretary.

If you hold your shares in street name, you must contact your broker, bank, or other nominee for specific instructions on how to change or revoke your vote.

What constitutes a "quorum" for the meeting?

The presence, in person or by proxy, of the holders of record of a majority of the outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting, but if a quorum should not be present, the meeting may be adjourned from time to time until a quorum is obtained.

  71

Questions and Answers Table of Contents

What is the voting requirement to approve each of the proposals, and how are votes counted?

Proposal	Description	Votes Required for Approval	Effect of Abstention
1	Election of Nominated Directors	Affirmative vote of a majority of the votes cast for the election of directors during the virtual Annual Meeting	An abstention will not count as a vote cast and therefore will not affect the outcome of the vote. An incumbent director nominee who is not elected is required to tender his or her resignation, which will be accepted or rejected by the Board as more fully described in "Proposal 1 - Election of Nominated Directors."
2	Advisory vote to approve named executive officer compensation	Affirmative vote of a majority of the shares present in person or represented by proxy and entitled to vote on the subject matter	An abstention will effectively count as a vote cast against this proposal.
3	Ratification of Ernst & Young as independent registered public accounting firm for the year ending December 31, 2024	Affirmative vote of a majority of the shares present in person or represented by proxy and entitled to vote on the subject matter	An abstention will effectively count as a vote cast against this proposal.

Cumulative voting is not permitted in the election of directors. Shares of a shareholder who abstains from voting on any or all proposals will be included for the purpose of determining the presence of a quorum. Broker non-votes on any matter as to which the broker has indicated on the proxy that it does not have discretionary authority to vote will be treated as votes not cast or as shares not entitled to vote with respect to that matter and will not affect the outcome of the vote. However, such shares will be considered present and entitled to vote for quorum purposes so long as they are entitled to vote on at least one other matter.

Who pays for the solicitation of proxies?

The cost of soliciting proxies will be borne by Arcosa. In addition to the use of postal services or the Internet, proxies may be solicited by directors, officers, and employees of Arcosa (none of whom will receive any additional compensation for any assistance they may provide in the solicitation of proxies) in person or by telephone. Arcosa has hired Georgeson, Inc. to assist in the solicitation of proxies at an estimated cost of $13,500 plus expenses.

What does it mean if I receive more than one Notice, Proxy Card, or voting instructions?

This means that you have multiple accounts in which you own our Common Stock. Please vote all Notices, Proxy Cards, or voting instructions from us to ensure that all of your shares of Common Stock are voted.

What is "householding"?

In order to reduce expenses, we are taking advantage of certain SEC rules, commonly known as "householding," that permit us to deliver, in certain cases, only one Notice, Annual Report, or Proxy Statement, as applicable, to multiple shareholders sharing the same address, unless we have received contrary instructions from one or more of the shareholders. If you received a householded mailing this year and would like to have additional copies of the Notice, Annual Report, Proxy Statement, or other proxy materials sent to you, please submit your request directed to our Corporate Secretary, Arcosa, Inc., 500 N. Akard St., Suite 400, Dallas, TX 75201, or by telephone at 972-942-6500. If you hold your stock in street name, you may revoke your consent to householding at any time by notifying your broker.

If you are currently a shareholder sharing an address with another of our shareholders and wish to have your future proxy statements and annual reports householded, or your materials are currently householded and you would prefer to receive separate materials in the future, please contact our Corporate Secretary at the above address or telephone number.

72

Other Business

Management of Arcosa is not aware of other business to be presented for action at the Annual Meeting; however, if other matters are properly presented for action at the meeting, it is the intention of the persons named as proxies in the Proxy Card or electronic voting form to vote in accordance with their judgment on such matters.

By Order of the Board of Directors,

Annex A

Reconciliation of Non-GAAP Financial Measures

This Proxy Statement contains financial measures that have not been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). This non-GAAP financial information is provided as supplemental information for investors and is not in accordance with, or an alternative to, GAAP. Additionally, these non-GAAP measures may be different than similar measures used by other companies.

Reconciliations of each of the non-GAAP financial measures to the closest GAAP measure are set forth in the tables below.

Enterprise Adjusted EBITDA

($ in millions)

"Enterprise Adjusted EBITDA" is defined solely for purposes of this Proxy as enterprise operating income (loss) from continuing operations before interest, income taxes, depreciation, depletion, and amortization, extraordinary adjustments to asset values (gains or losses), asset impairment charges, material restructuring/reorganization expenses, gains or losses on extraordinary dispositions, gains or losses from currency translation adjustments, acquisition or divestiture-related gains/losses or expenses (including transaction expenses and purchase price accounting adjustments), expenses to comply with COVID-related policies or regulations, the impact of changes in accounting rules, any changes to federal, state, or local tax laws that impact the Company's tax liability, in each case as approved by the HR Committee, and any other adjustments the HR Committee deems appropriate. GAAP does not define Enterprise Adjusted EBITDA and it should not be considered as an alternative to earnings measures defined by GAAP, including net income. We use Enterprise Adjusted EBITDA in this Proxy to assess the operating performance of our consolidated business, as a metric for incentive-based compensation, and as a basis for strategic planning and forecasting as we believe that it closely correlates to long-term shareholder value. As a widely used metric by analysts, investors, and competitors in our industry, we believe Enterprise Adjusted EBITDA also assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion, amortization, and other items which can vary significantly depending on many factors.

ADJUSTED SEGMENT EBITDA

($ in millions)

"Segment EBITDA" is defined as segment operating profit plus depreciation, depletion, and amortization. "Adjusted Segment EBITDA" is defined solely for purposes of this Proxy as Segment EBITDA adjusted for certain items that are not reflective of the normal earnings of our business. GAAP does not define Segment EBITDA or Adjusted Segment EBITDA and they should not be considered as alternatives to earnings measures defined by GAAP, including segment operating profit. We use Adjusted Segment EBITDA in this Proxy to assess the operating performance of our businesses, as a metric for incentive-based compensation, and as a basis for strategic planning and forecasting as we believe that it closely correlates to long-term shareholder value. As a widely used metric by analysts, investors, and competitors in our industry we believe Adjusted Segment EBITDA also assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion, amortization, and other items, which can vary significantly depending on many factors.

GROUP ADJUSTED EBITDA

"Group Adjusted EBITDA" is defined solely for purposes of this Proxy as group operating profit (loss) from continuing operations before interest, income taxes, depreciation, depletion, and amortization, extraordinary adjustments to asset values (gains or losses), asset impairment charges, material restructuring/reorganization expenses, gains or losses on extraordinary dispositions, gains or losses from currency translation adjustments, acquisition or divestiture-related gains/losses or expenses (including transaction expenses and purchase price accounting adjustments), expenses to comply with COVID-related policies or regulations, the impact of changes in accounting rules, any changes to federal, state or local tax laws that impact the Company's tax liability, in each case as approved by the HR Committee, and any other adjustments the HR Committee deems appropriate. GAAP does not define Group Adjusted EBITDA and it should not be considered as alternatives to earnings measures defined by GAAP, including operating profit. We use Group Adjusted EBITDA as a metric for incentive-based compensation.

PRE-TAX RETURN ON CAPITAL

($ in millions)

"Pre-Tax Return on Capital" is defined solely for purposes of this Proxy as Enterprise Adjusted EBITDA (as defined above) divided by ((Current Assets - Current Liabilities + Current Portion of Long-Term Debt) + Net Plant, Property and Equipment). Balance Sheet items will be calculated using an average of 5 points (beginning of Q1, End of Q1, End of Q2, End of Q3, End of Q4). GAAP does not define Pre-Tax Return on Capital and it should not be considered as alternatives to earnings measures defined by GAAP, including operating profit and net income. We use Pre-Tax Return on Capital in this Proxy to assess the operating returns of our business, as a metric for incentive-based compensation, and as a basis for strategic planning and forecasting as we believe that it closely correlates to long-term shareholder value.

ADJUSTED EPS

"Adjusted Earnings Per Share" or "Adjusted EPS" is defined solely for purposes of this Proxy as reported diluted earnings (loss) per share from continuing operations before extraordinary adjustments to asset values (gains or losses), asset impairment charges, material restructuring/reorganization expenses, gains or losses on extraordinary dispositions, gains or losses from currency translation adjustments, acquisition or divestiture-related gains/losses or expenses (including transaction and separation expenses, and purchase price accounting adjustments), expenses to comply with COVID-related policies or regulations, any changes to federal, state, or local tax laws that impact the Company's tax liability, the impact of changes in accounting rules, in each case as approved by the HR Committee, and any other adjustments the HR Committee deems appropriate. GAAP does not define "Adjusted Diluted EPS" and it should not be considered as an alternative to earnings measures defined by GAAP, including diluted EPS. We use this metric in this Proxy to assess the operating performance of our consolidated business. We adjust diluted EPS for certain items that are not reflective of the normal operations of our business to provide investors with what we believe is a more consistent comparison of earnings performance from period to period.
