DEAR FELLOW STOCKHOLDERS,

We would like to express our gratitude to the entire Reliance family for our strong performance and forward progress in 2023 and for placing safety at the forefront of our operations. Continuing to execute our unique and sustainable business model with a focus on growth and delivering increasing value to our customers resulted in the second highest sales, profitability, and cash flow generation in our Company’s history. Importantly, these results were achieved in a challenging environment with ongoing inflationary headwinds and declining metal prices.

We thank our loyal and valued customers for relying on us for quick and accurate deliveries of high-quality products, and we are grateful for the longstanding relationships with our suppliers who continue to support us through all market cycles.

We also appreciate our stockholders and their confidence in our future as our stock price reached new heights, increasing 38% in 2023, and representing a 17.6% compound annual growth rate since our IPO in 1994.

More Than Metal

On February 15, 2024, we unveiled a corporate rebranding to Reliance, Inc. to portray the Company’s evolution and reinforce our position as a leading diversified metal solutions provider. Retaining “Steel & Aluminum” in our corporate name limited the perception of Reliance because we have evolved into a company that is so much more than metal. Over the years we have become stronger, more collaborative, and focused as we further differentiate and diversify Reliance. We are a best-in-class family of companies working collaboratively to deliver exceptional service to our customers, return value to our stockholders, provide a safe environment where our employees are proud to work, and positively contribute to our communities.

Our company-wide community involvement efforts have united under the Reliance Cares banner. In 2023, we significantly increased our impact in our communities through expanded programs driven by our employees throughout our Family of Companies.

We are pleased that our new identity captures the essence of who we have always been and always will be. We are more than metal. We are industrial strength.

Employee Health & Safety

The health, safety, and wellbeing of our employees and communities throughout all aspects of our business. Employee safety remains fundamental to our day-to-day operational focus. Our 2023 Total Recordable Incident Rate (TRIR) of 1.96 was significantly lower than the 2020 Metals Service Center Institute (“MSCI”) average of 3.5 and we remain committed to living a culture of safety and reducing the number of injuries to zero. “Be SMART. Be Safe.” was the theme of our 2023 company-wide SMART Safety program to promote proactive commitment, engagement, and accountability throughout the organization.

Strong Operational and Financial Performance

We finished 2023 with $14.8 billion in sales and $22.64 of diluted earnings per share, both representing the second highest results in Reliance history. We emphasized “Smart, Profitable Growth” in 2023, increasing our volumes above

investor.reliance.com

2024 Proxy Statement /i

TABLE OF CONTENTS

industry trends while maintaining a strong full year gross profit margin of 30.7%, near the high end of our estimated sustainable range. Our resilient business model – including strong pricing discipline and significant capital reinvestment in the business to increase our capacity and value-added processing capabilities – was instrumental to these results.

In 2023, Reliance performed value-added processing on 50.6% of sales orders, up from 50.2% in 2022. We maintained a small average order size of $3,210 with approximately 40% of orders delivered to customers within 24 hours. We serve more than 125,000 customers in a broad range of industries including non-residential construction (including infrastructure), aerospace, automotive, broader manufacturing, semiconductor, and more.

Disciplined Capital Allocation Strategy

Our strong profitability and effective management of working capital enabled us to generate $1.67 billion in annual cash flow from operations, the second highest we have ever reported. Our strong cash flow facilitated our execution of a disciplined and balanced capital allocation strategy through investments in both growth and stockholder returns. In 2023, our operating cash flow funded a record $469 million of capital expenditures, $238 million of cash dividends, and $480 million of share repurchases, resulting in a 3.2% reduction in total shares outstanding.

Growth

In addition to increasing our volumes through market share gains, we deployed capital into various growth projects that further enhanced our value-added capabilities, maintained, upgraded, and improved our operating facilities, and funded expansion into new markets. Greenfield locations contributed meaningfully to our volume growth in 2023. As a result of these growth activities, our 2023 tons shipped increased 3.7% compared to the industry increase of 1.5% as reported by MSCI. We continue to identify many opportunities to support our customers and suppliers as they grow. Our capital expenditure budget for 2024 is $425 million with approximately two-thirds targeting growth initiatives.

In addition to our organic growth efforts, we completed one acquisition in 2023 and announced two acquisitions in the first quarter of 2024:

•

Southern Steel Supply, LLC (“Southern Steel”) – an established service center located in Memphis, Tennessee, distributing primarily carbon steel products – was acquired in May 2023. Southern Steel further expanded our reach in the Southeastern part of the U.S. Southern Steel’s 2022 sales were approximately $63 million.

•

Cooksey Iron & Metal Company (“Cooksey”) – a well-known regional metals service center based in Tifton, Georgia, with a focus on carbon long products and plate – was acquired in February 2024. Cooksey’s strong reputation for premium customer service and rapid delivery to its customers along with its presence in the fast-growing Southeastern market both strengthens and expands our position in the region. Cooksey’s 2023 sales were approximately $90 million.

•

American Alloy Steel, Inc. (“American Alloy”) – a reputable, Houston, Texas-based national distributor of specialty carbon and alloy steel plate and round bar, as well as a plate fabricator – was acquired in April 2024. American Alloy has strong, decades-long relationships with both customers and suppliers and a solid reputation for customer service and product expertise. American Alloy’s 2023 sales were approximately $310 million.

TABLE OF CONTENTS

Stockholder Returns

Driven by our ongoing commitment to delivering increased value to our stockholders, we returned $718 million through dividends and share repurchases in 2023. We have paid regular quarterly cash dividends for 64 consecutive years without reduction or suspension and have increased our dividend 31 times since our 1994 IPO, including our most recent increase of 10% to $1.10 per share ($4.40 per share on an annualized basis) in the first quarter of 2024. Our recently announced $1.5 billion share repurchase authorization, coupled with our strong balance sheet and cash generation, allow us to remain opportunistic. We repurchased approximately 1.9 million shares of RS common stock at an average cost of $255.30 per share, for a total of $480 million, in 2023.

We are very proud of our strong financial position, which has enabled us to reinvest back into our business to support growth while concurrently returning approximately 45% of our net income and 58% of our free cash flow to our stockholders over the past three years.

85 Years of Excellence

2024 is a milestone year for Reliance in which we celebrate our 85th anniversary and our 30th anniversary as a publicly traded company. We are proud of our history and remain anchored to our core business model and values as we move forward into the future. Our unwavering commitment to employee safety and wellbeing, profitable growth, working collaboratively, and improving the communities in which we live and work encompass why Reliance is so much more than metal.

Longer-term, we remain excited about the many growth prospects anticipated under the Infrastructure Bill, the CHIPS Act, and the Inflation Reduction Act, as well as the onshoring and near-shoring activities in the markets we serve.

Thank you to all of our employees, customers, suppliers, and stockholders for your continued confidence in and ongoing support of Reliance.

Sincerely,


	Karla R. Lewis President and Chief Executive Officer (Center)			Stephen P. Koch Executive Vice President and Chief Operating Officer (Right)			Arthur Ajemyan Senior Vice President and Chief Financial Officer (Left)

Modernization of the Reliance brand symbolizes how the Company has become much more than just a distributor of steel and aluminum.

TABLE OF CONTENTS

~~PROXY SUMMARY~~

CORPORATE CITIZENSHIP AND SUSTAINABILITY

We recognize that we have a corporate social responsibility not only to our investors, but also to our ~~people,~~employees, their families and the communities in which we live and conduct our business. Accountability to our stockholders, employees, and communities, and a commitment to ethical business practices, motivates and anchors us. Our responsibility to stockholders requires a diligent commitment to excellence and a focus on sustainable profitability. This commitment to excellence also requires that we set the highest standards for business practices, ensure a safe and productive workplace for our employees, are stewards of the natural environments in which we operate, and share our success by giving back to our communities.

We are committed to promoting the health, safety, and wellbeing of our employees and their families, as well as supporting the communities in which we live and conduct our business. We strive to foster a culture of excellence by generating industry-leading results while operating responsibly, safely and ethically, minimizing environmental impacts of our business, and leveraging the diversity of talent and perspectives within our family of companies.

Our commitment to corporate citizenship and sustainability is highlighted in our six core values—People, Diversity, Integrity, Leadership, Service and Partnership. We have always focused on delivering strong financial results and returns to our stockholders, and we remain committed to doing so in a sustainable manner that respects the communities in which we operate.

In 2021, we completed a materiality assessment to determine the environmental, social and governance ("ESG") issues that are most critical to our business and our stakeholders. As a result of the materiality assessment, we determined that Reliance’s most significant ESG issues are: (i) the health and safety of our employees; (ii) human capital management; (iii) emissions from company-operated trucks that deliver our products; and (iv) our overall energy usage. We expect to update this materiality assessment on a periodic basis to ensure it reflects changes in our business.

~~We look forward to communicating our progress over time as we continue to maintain focus on ESG matters.~~ Please refer to the ESG section of our website at https://~~www.rsac.com/~~www.reliance.com/environmental-social-and-governance/ for further information on our environmental, social and governance matters and initiatives.

~~TABLE OF CONTENTS~~

~~PROXY SUMMARY~~

~~Set forth below are some highlights of our corporate responsibility and sustainability initiatives.~~

									~~PEOPLE AND DIVERSITY~~
									The health and safety of our employees, customers, suppliers and communities is our most important core value. Our safety programs are designed around recognized standards with appropriate variations addressing the multiple jurisdictions and regulations, specific hazards and unique working environments of our operations.
									~~Our SMART Safety program focuses on embedding our culture of safety across all of our operations.~~
		~~Worker Safety~~							We strive to have zero fatalities and no life-threatening or life-altering injuries and illnesses from working at our facilities. Our executive team supports a safety management system that includes policies, standard practices and goals at our facilities, including: • ~~conducting regular safety assessments;~~ • ~~monitoring best practices and compliance with regulatory requirements;~~ • ~~training our employees to improve safety practices;~~ • ~~integrating video-based technology and safety programs into substantially all Company-operated trucks; and~~ • ~~maintaining emergency preparedness and response plans.~~
									We proactively identify areas of improvement and reinforce positive employee behaviors in order to enhance safety practices and reduce or eliminate incidents. In our facilities, behavioral safety culture is a primary focus, with an increased emphasis on "near-miss" reporting and resolution. We define a near-miss event as a situation where no personal injury was sustained and no property was damaged, but given a slight shift in time or position, injury and/or damage could have occurred. We believe that this focus has increased awareness to potential incidents at our facilities.
									2022 was Reliance’s safest year ever! We utilize a mixture of indicators to assess the health and safety performance of our domestic operations. Lagging indicators include the OSHA Total Recordable Incident Rate ("TRIR") and average Department of Transportation Recordable Accident Rate per million miles ("DOT Rate"). ~~The following table sets forth the TRIR and DOT Rate for each of the last three years ended December 31.~~

Safety Indicator 2022 2021 2020
TRIR 1.61 2.12 1.86
DOT Rate 0.55 0.54 0.60

Our focus on safety is evident in our TRIR, which is lower than the 2020 Metals Service Center Institute average of 3.5. A lower TRIR means that fewer people are injured and fewer lives are impacted. We have not identified a universally accepted and annually updated benchmarking standard for DOT Rate but believe our rate represents safest driving practices.

									~~PEOPLE AND DIVERSITY~~
		~~Employees~~							To help attract and retain the best employees, we offer competitive compensation and benefits. In addition to base salaries, our compensation programs can include annual bonuses, stock-based compensation awards, a 401(k) plan with employer matching opportunities, healthcare and insurance benefits, health savings and flexible spending accounts.
									We strive to make a positive impact on the lives of our employees by providing a workplace culture focused on safety and wellbeing, economic stability, and opportunities for continued skills development and knowledge building. All U.S. full-time (work 30 hours or more per week) non-union employees, from our corporate officers to our non-exempt workforce, are eligible for benefits under our health and wellness program. Over 99% of our employees (72% of whom are hourly) are eligible for our health and wellness program. We believe that our employee-focused initiatives and benefits provide long-term positive impacts towards minimizing turnover, enhancing employee safety, health and welfare, engagement, productivity, and loyalty. Through our culture, benefits, and opportunities, we endeavor to make Reliance a place to build a long-term career, rather than just have a job.
									~~We believe that we provide industry-leading healthcare benefits to our employees. We funded approximately 86% of the costs associated with our U.S. employees’ health insurance coverage in 2022.~~
									As part of our comprehensive benefits offering, we provide employees and their covered spouses/domestic partners with on-site health screenings, individualized health and wellness assessments and personalized wellness coaching. This one-on-one coaching program integrates phone and mail-based communications and is designed to support employees’ physical and mental health by providing individualized tools and coaching resources to help improve or maintain their health status and encourage engagement in healthy behaviors.

~~PROXY SUMMARY~~

									~~PEOPLE AND DIVERSITY~~
		~~Diversity, Equity and Inclusion~~							We believe that superior Company performance requires contributions from a diverse workforce that includes a variety of employee experiences, backgrounds, and characteristics. We are committed to providing fair and unbiased opportunities and hiring, developing and supporting a diverse and inclusive workforce.
									We offer an unbiased opportunity for our employees to perform, contribute, and achieve their career aspirations. We embrace and encourage one another’s unique perspectives and experiences because we believe these characteristics foster a company-wide culture of innovation and creative problem solving contributing to individual and company performance.
									We value teamwork as an ongoing practice that calls for inclusiveness, representation, and participation and that engages various groups and points-of-view. We strive to recruit high performers with a desire to achieve at industry-leading levels and hire people from all backgrounds, experiences, and skillsets. We are committed to providing a work-life balance and continually promote the understanding of and appreciation for performance and diversity in our workplace and community.
									Women comprise 33% of the directors nominated to our Board of Directors in 2023 and serve in key executive leadership roles at the Company, including: President and Chief Executive Officer; Senior Vice President, Chief Information Officer; Vice President, Corporate Initiatives; Vice President, Health & Human Resources; and Vice President, Tax. In addition, our non-executive Chairman of the Board identifies as American Indian and is a member of the Citizen Potawatomi Nation.
									We expect and require fair, equitable, and respectful treatment of and by all our employees. Our commitment to diversity and inclusion is also reinforced by our Code of Conduct, which forbids employment discrimination or harassment based on race, color, sex (including pregnancy, childbirth, and related medical conditions), national origin, religion, age, disability, genetic information, veteran status, sexual orientation, marital status, or any other characteristic protected by applicable law.

									~~INTEGRITY AND LEADERSHIP~~
		~~Code of Conduct and Related Policies Promoting Ethical Behavior~~							~~Our Company-wide ethics and compliance program is designed to ensure that integrity guides every decision we make each and every day.~~
									~~Our entire workforce is required to comply with our ethics policies and procedures as well as all applicable laws and regulations.~~
									~~Our Code of Conduct and our Anti-Bribery and Anti-Corruption Policy apply to all Company directors, officers, and employees and set forth expectations regarding how we conduct business worldwide.~~
									~~Training on the Code of Conduct and Anti-Bribery and Anti-Corruption Policy is assigned to all new employees upon hire and existing employees also complete regular training.~~
									We maintain a confidential hotline and website to allow persons to report, without fear of retaliation, any inappropriate acts or omissions relating to our policies and practices. The hotline and website are provided by an independent third-party and are available worldwide and are translated into the local languages at each of our operations.
									All hotline and website reports/inquiries are administrated by the Vice President, Enterprise Risk. To date, the significant majority of these reports and inquiries have related to employee human resources with a lesser number pertaining to safety and financial reports. The Audit Committee is informed of all hotline and website reports as well as any other matters, whether arising through the hotline, website, management, or otherwise, involving accounting, internal control, or auditing matters.
									The Reliance Policy on U.S. Political Activity and Spending Practices requires that all political contributions, payments or other support to U.S. political parties, committees or candidates from corporate funds must be made in accordance with applicable campaign finance laws. Company funds or resources cannot be used for, or contributed to, political campaigns or practices under any circumstances unless pre-approved by the Company’s General Counsel. However, it is acceptable for Company employees to make lawful personal political contributions as the Company supports its employees’ involvement in the political process and their communities.
		~~Tax Transparency~~							We believe in having a positive impact in the communities in which we operate and we support corporate tax laws that incentivize innovation, investment, and job creation. We are committed to complying with tax laws in a responsible manner and paying and reporting our taxes on time. As part of our commitment, we do not operate in "tax havens". We believe that a "tax haven" can be defined as a country imposing no or only nominal taxes; having a lack of effective exchange of information; and having a lack of transparency in the operation of the legislative, legal or administrative provisions.
		~~Tax Transparency~~							For fiscal year 2022, our worldwide income tax payments were $692.4 million, and our effective tax rate was 24.1%. Reliance also incurred $140.7 million in real estate, payroll, franchise, personal property and miscellaneous taxes in 2022.

��	~~Environment and Sustainability~~	~~We are committed to mitigating the impact that our products and operations may have on the environment.~~
		We are not a metals producer or mill—we operate metals service centers. As a distributor and "first-stage" processor of metal products, our operations, by their nature, have a limited environmental impact as we do not emit significant amounts of carbon dioxide or other greenhouse gases.
		Our operations process and distribute steel and aluminum, which are inherently sustainable products, as they are some of the most commonly-recycled materials in the United States and can be 100% recycled without loss of quality.
		~~In 2022, we reintroduced over 197 thousand tons of recycled scrap material into the manufacturing life cycle.~~
		As a processor and distributor of metals, and not a producer, we acknowledge and embrace our role in protecting the environment and are currently assessing our impacts. Our strong desire is to identify and prioritize areas of improvement.
		~~In the last four years, the Company has invested approximately $9.7 million in LED and energy-efficient lighting and the installation of solar power equipment at its facilities.~~
		~~In 2023, the Company has budgeted over $15.4 million for capital expenditures related to the installation of solar power equipment, LED lighting and energy-efficient equipment.~~

									~~(1)~~ Scope 1 emissions (in metric tons of carbon dioxide equivalent) represent direct greenhouse gas (GHG) emissions resulting from fuel consumed to operate our trucking fleet and facility operations. As a distributor, approximately 70%-75% of our Scope 1 emissions arise from fuel consumption for product delivery. Scope 1 (GHG) emissions are derived from our fleet of approximately 1,720 trucks, 315 locations and 36.5 million square feet of facility space.
									~~(2)~~ Scope 2 emissions (in metric tons of carbon dioxide equivalent) represent indirect GHG emissions from purchased electricity. Emissions at each facility vary based on amount of energy purchased and emissions efficiency of grid energy source.

									~~SERVICE AND PARTNERSHIPS~~
		~~Community Service~~							~~Reliance is committed to investing in and enriching the communities in which we live and work.~~
									Giving back to those in need and enriching people’s lives is a deep-rooted philosophy embedded in our Reliance Cares Social Responsibility program through which we support non-profit organizations that align with our three giving pillars: (i) education; (ii) community enrichment; and (iii) employee emergency assistance. Our partnerships with non-profit organizations provide employees with volunteering opportunities to engage and give back to their local communities.
									Our dedication to each and every member of our family of companies is the foundation for Employee Emergency Relief Fund dedicated to supporting employees impacted by natural disasters and the COVID-19 pandemic.
									Through employee funded contributions, matched dollar-for-dollar by Reliance, we have been able to provide approximately 1,000 grants to employees (including over 170 grants to support employees and their families responding to COVID-19-related personal impacts) since the inception of Reliance Cares in 2017.

VOTING INFORMATION

We are furnishing this proxy statement to the holders of our common stock in connection with the solicitation of proxies on behalf of our Board of Directors for use at the Annual Meeting.

The Board of Directors selected Arthur Ajemyan, our Senior Vice President, Chief Financial Officer, and William A. Smith II, our Senior Vice President, General Counsel and Corporate Secretary, or their designees, to be named as proxyholders to vote the shares of common stock represented by the proxies at the Annual Meeting. Reliance will pay the cost to solicit the proxies. The Board of Directors will solicit proxies by mail, by telephone, and electronically via the internet. In addition, certain of our officers and agents may solicit proxies by telephone, email and personal interview (the cost of which will be nominal). We expect that banks, brokerage houses and other custodians, nominees and fiduciaries will forward soliciting material to beneficial owners and obtain authorizations to execute proxies. We will reimburse the reasonable out-of-pocket expenses they incur to forward our proxy materials.

We have retained D.F. King & Co., Inc. ("(“D.F. ~~King"~~King”) to assist in the distribution and solicitation of proxies. Based on our agreement with D.F. King, we anticipate paying fees of approximately ~~$10,500,~~$11,000, plus-out-of-pocket expenses, for these services. Your bank, broker or financial institution is not able to vote on your behalf for the election of directors, or on any compensation or incentive award plan matter unless you provide specific instructions by completing and returning a proxy or voting instruction form or by following instructions provided to you by your bank, broker or financial institution to vote your shares which often include instructions on how to vote your shares via telephone or the internet. Voting your shares is important to ensure that you have a say in the governance of our Company.

We intend only the ~~five~~four matters described in this proxy statement to be presented at the Annual Meeting. However, we may also transact any other business that properly comes before the meeting or any adjournments thereof.

Unless you instruct us otherwise on the proxy, each proxy will be voted FOR the election of all of the nominees named herein as ~~directors,~~ directors: FOR the approval of the compensation of the Company’s named executive ~~officers,~~ officers; FOR the ratification of KPMG LLP as our independent registered public accounting firm for ~~2023,~~ 2024; and ~~1 YEAR~~FOR as the ~~frequency with which stockholders will provide an advisory vote on~~amendment to the ~~compensation of our named executed officers,~~Reliance, Inc. Second Amended and ~~AGAINST~~Restated 2015 Incentive Award Plan. ~~the stockholder proposal relating to adoption of a policy regarding separation of the roles of Chairman and Chief Executive Officer.~~

We intend to make this proxy statement and accompanying material available to each stockholder on the internet beginning on or about April ~~5, 2023.~~3, 2024. An annual report, including a letter to our stockholders from our President and Chief Executive Officer; Executive Vice President and Chief Operating Officer and our Senior Vice President, Chief Financial Officer, and an Annual Report on Form 10-K, and an annual report to stockholders will also be available electronically. Some stockholders will receive these materials by mail and other stockholders may request copies of these materials at no cost. The annual report and stockholder letter are not incorporated in, and are not a part of, this proxy statement and do not constitute proxy-soliciting material.

If you are a stockholder of record and execute a proxy or submit a proxy via the internet or telephone, the proxy may be revoked at any time before it is voted:

•

by filing with our Corporate Secretary either an instrument revoking the proxy or a proxy bearing a later date, duly executed in either case; or

•

by voting electronically at the virtual meeting.

Any written instrument or later dated proxy should be sent or delivered to the Corporate Secretary at the address shown on the first page of this proxy statement and must be received prior to the Annual Meeting.

~~TABLE OF CONTENTS~~

~~VOTING INFORMATION~~

In addition, prior to the deadline for internet or telephone voting, you may change your vote using the internet or telephone method, in which case only your latest internet or telephone proxy submitted before the deadline will be counted.

If you hold your shares through a broker, bank, financial institution, or other nominee, then you are a beneficial holder, and you may change your vote by complying with the procedures contained in the voting instructions provided to you by your broker, bank, financial institution or other nominee.

Even if you currently plan to participate in the Annual Meeting, the Company recommends that you also submit your proxy as described above so your vote will be counted if you later decide not to participate at the Annual Meeting. If you submit your vote by proxy and later decide to vote electronically at the Annual Meeting, the vote you submit at the Annual Meeting will override your proxy vote.

The presence at the virtual meeting or by proxy of the holders of a majority of the shares entitled to vote at the meeting shall constitute a quorum for the transaction of business. Broker non-votes and abstentions are counted for purposes of

determining whether a quorum is present. A broker non-vote occurs when a nominee holding shares for a beneficial owner (i.e., in ~~"street name"~~“street name”) does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner. We believe that nominees only have discretionary voting power with respect to the ballot item addressing the ratification of our independent registered public accounting firm.

INFORMATION CONCERNING OUR COMMON STOCK

Our only voting securities are shares of common stock, par value $0.001 per share. As of the record date of March 28, ~~2023,~~2024, we had a total of ~~58,839,910~~57,425,841 shares of common stock issued and outstanding, all of which may be voted at the Annual Meeting. Only holders of shares of record on our books at the close of business on the record date will be entitled to vote at the Annual Meeting.

Each nominee for election as a director at the Annual Meeting will only be elected if the votes cast "“FOR"” such nominee exceed the number of votes cast "“AGAINST"” such nominee, with abstentions and broker non-votes not counted as either votes "“FOR"” or "“AGAINST"” that nominee’s election. As required by the Company’s Bylaws, in the event that an incumbent director fails to receive a majority of votes cast in an uncontested election, such incumbent director is required to submit his or her resignation to the Board of Directors within ten calendar days of the date of the certification of the election results. Pursuant to the procedures set forth in our Bylaws, the Nominating and Governance Committee will make a recommendation to the Board of Directors within ten calendar days as to whether to accept or reject the resignation, or whether other action should be taken. The Board of Directors will then act on the resignation, taking into account the Nominating and Governance Committee’s recommendation, and the Company will publicly disclose such decision by the Board of Directors with respect to the director nominee. Each of the Nominating and Governance Committee, in making its recommendation, and the Board of Directors, in making its decision, may consider any factors and other information that they consider appropriate and relevant. A director who tenders his or her resignation is not permitted to participate in the recommendation of the Nominating and Governance Committee or the decision of the Board of Directors with respect to his or her resignation.

The affirmative vote of a majority of votes present at the ~~Virtual Meeting~~virtual meeting or by proxy and entitled to vote on the matter is required to: (i) approve, on a non-binding advisory basis, the compensation of the NEOs; (ii) ratify the engagement of KPMG LLP as our independent registered public accounting firm for ~~2023;~~2024; and (iii) approve the ~~stockholder proposal relating~~amendment to ~~adoption of a policy regarding separation of~~ the ~~roles of Chairman~~Reliance, Inc. Second Amended and ~~Chief Executive Officer. Accordingly, abstentions~~Restated 2015 Incentive Award Plan. Abstentions will count as votes "~~AGAINST~~"against such proposals. For the advisory (non-binding) vote concerning the frequency of future votes on executive compensation (Proposal No. 4), if a majority is not received by any of the frequency choices, the frequency choice that receives a plurality of the votes cast will be considered the stockholders’ preferred frequency for holding future (non-binding) votes on executive compensation. Accordingly, abstentions will have no effect on such proposal.

Broker non-votes will have no effect on Proposal Numbers 1, 2 ~~4 and 5.~~or 4. Because the ratification of the appointment of KPMG LLP (Proposal No. 3) is considered a ~~"routine"~~“routine” proposal, a broker holding shares as the nominee for a beneficial owner may vote for the proposal without voting instructions and, accordingly, we do not expect there to be any broker non-votes on Proposal No. 3.

The absence of a mark does not necessarily indicate that the director does not possess that qualification or skill.

A majority of the votes cast is required for the election of each director at the ~~2023~~2024 Annual Meeting. Neither Reliance nor your bank, broker or financial institution is able to vote on your behalf for the election of directors unless you provide specific instructions by completing and returning a proxy or voting instruction form or you follow instructions provided to you by your bank, broker or financial institution, which often include instructions on how to vote your shares via telephone or the internet.

Our Board ~~of Directors~~ currently has ~~ten~~nine members. ~~John G. Figueroa~~James D.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE ~~"FOR"~~“FOR” THE APPROVEL OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

We are asking our stockholders to approve, on an advisory, non-binding basis, the compensation of our NEOs as disclosed in this proxy statement. It is Reliance’s current policy to provide our stockholders with an opportunity to approve the compensation of our NEOs each year at the Annual Meeting. Accordingly, we anticipate that the next such vote will occur at the 2025 Annual Meeting of Stockholders.

We believe that the information we have provided below in the “Compensation Discussion and Analysis” section of this proxy statement demonstrates that our executive compensation program was designed appropriately and is working to ensure management’s interests are aligned with our stockholders’ interests to support long-term value creation.

Accordingly, we are asking our stockholders to approve, ~~this policy, on~~in an advisory, non-binding ~~basis, in Proposal No. 4. Subject to the results of Proposal No. 4 and the decision of the Board, we anticipate that the next~~ vote, ~~to approve the compensation of our NEOs will occur at the 2024 Annual Meeting of Stockholders.~~

In voting on this proposal, the Board of Directors encourages you to consider the detailed discussion of compensation matters in the Compensation Discussion and Analysis section, or CD&A, beginning on page 38.

~~The Board of Directors recommends that stockholders vote~~ ~~FOR~~ the following resolution:

"“RESOLVED, that the stockholders of Reliance, ~~Steel & Aluminum Co.~~Inc. approve, on an advisory basis, the compensation paid to Reliance, ~~Steel & Aluminum Co.~~Inc.’s named executive officers, as disclosed in the ~~2023~~2024 Proxy Statement pursuant to the Securities and Exchange Commission’s compensation disclosure rules, including the CD&A, the Summary Compensation Table and other compensation tables and the accompanying footnotes and narratives and any related material."”

Because your vote is advisory, it will not be binding upon the Board. However, the Board values our stockholders’ opinions, and the Compensation Committee will take into account the outcome of the vote when considering future executive compensation decisions. The affirmative vote of a majority of votes present at the virtual meeting or by proxy and entitled to vote is required to approve this proposal.

Neither Reliance nor your bank, broker or financial institution is able to vote on your behalf to support the Company’s executive compensation unless you provide specific instructions by completing and returning a proxy or voting instruction form or you follow instructions provided to you by your bank, broker or financial institution, which often include instructions on how to vote your shares via telephone or the internet.

Audit fees relate to services rendered in connection with the audit of our annual financial statements and internal control over financial reporting, quarterly review of financial statements, audit services provided in connection with statutory and regulatory filings, including consents and comfort letters, and discussions surrounding the proper application of financial accounting and/or reporting standards.

Audit-related fees are those fees for services provided by the independent registered public accounting firm that are reasonably related to the performance of the audit or review of our financial statements and not included as audit fees. Tax fees are fees and expenses for professional services rendered by KPMG LLP in connection with U.S. and foreign tax compliance and planning, and consultation and advice on tax examinations.

The Audit Committee approved all of these services in advance. The Audit Committee has adopted a pre-approval policy that requires that the Audit Committee approve in advance the services to be provided, the terms of the engagement letter, and all associated fees set forth in such letter for the independent registered public accounting firm. In addition, the Audit Committee will review proposed audit, audit-related, tax and other services that management desires the independent registered public accounting firm to perform to ensure that such services and the proposed fees related to the services will not impair the independent registered public accounting firm’s independence and that such services and fees are consistent with the rules established by the SEC. Each quarter, the Chief Financial Officer of the Company reports to the Audit Committee which services, if any, were performed and the amount of any fees that were incurred. The Audit Committee has delegated to the Chief Financial Officer the authority to add to, amend or modify the list of services to be provided or the amount of fees to be paid; provided that the Chief Financial Officer will report any action taken to the Audit Committee at its next scheduled meeting and provided further that the fees involved are reasonably expected to be less than ~~$100,000.~~$50,000.

~~PROPOSAL NO. 3 — RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM~~

The Audit Committee selected KPMG LLP as the Company’s independent registered public accounting firm for ~~2023.~~2024. KPMG LLP has served as the Company’s independent registered public accounting firm since 2008. The Board of Directors ratified this selection.

The Board of Directors believes there are significant benefits to having an independent registered public accounting firm with extensive history with the Company. These benefits include:

•

the high quality of their audit work and accounting advice, as a result of their institutional knowledge of our businesses, global operations, key risks, accounting policies, financial systems and internal control framework;

•

audit efficiency and effectiveness, resulting in a lower fee structure due to history and familiarity with our businesses; and

•

time and expense avoided by management and staff in onboarding a new independent registered public accounting firm.

At the Annual Meeting, stockholders will be asked to ratify and approve this selection. If the stockholders do not ratify the selection, the Audit Committee will reconsider whether or not to retain KPMG LLP, but may still retain the firm. Even if the selection is ratified, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

A representative of KPMG LLP is expected to be present at the Annual Meeting, will have an opportunity to make a statement if he or she desires to do so, and will be available to respond to appropriate questions. The affirmative vote of a majority of shares present at the virtual meeting or by proxy and entitled to vote is required to ratify the selection of KPMG LLP as our independent registered public accounting firm for ~~2023.~~2024. Because the ratification of the appointment of KPMG LLP is considered a ~~"routine"~~“routine” proposal, a bank, broker or financial institution holding shares as the nominee for a beneficial owner may vote for the proposal without voting instructions and, accordingly, we do not expect there to be any broker non-votes on this proposal.

PROPOSAL NO. 4 ~~— ADVISORY VOTE ON~~– AMENDMENT NO. 2 TO THE ~~FREQUENCY OF STOCKHOLDER APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS~~

SECOND AMENDED AND RESTATED 2015 INCENTIVE AWARD PLAN

THE BOARD OF DIRECTORS RECOMMENDS THAT ~~STOCKHOLDERS~~YOU VOTE FOR THE ~~OPTION OF "1 YEAR" AS~~AMENDMENT TO THE ~~FREQUENCY WITH WHICH STOCKHOLDERS WILL BE PROVIDED AN ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.~~

SECOND AMENDED AND RESTATED 2015 INCENTIVE AWARD PLAN

~~SEC rules require us~~We are asking our stockholders to ~~ask~~approve an amendment to the Reliance, Inc. Second Amended and Restated 2015 Incentive Award Plan (as proposed to be amended, the “Amended Plan”) to extend its term for an additional five-year period. On February 13, 2024, upon the recommendation of the Compensation Committee, the Board unanimously approved the Amended Plan, subject to approval by our stockholders at ~~least every six~~the Annual Meeting.

The Reliance, Inc. Amended and Restated 2015 Incentive Award Plan (the “Existing Plan”) was originally approved by our stockholders on May 20, 2015 and was further amended and restated following approval by our stockholders on May 20, 2020. The Existing Plan is the Company’s only compensation plan under which equity-based awards may be made to employees.

If approved by stockholders, the amendment will extend the duration of the Existing Plan by five years ~~how often they would like for us~~from February 24, 2025 to ~~hold advisory votes on~~February 24, 2030. In addition, the compensation of our NEOs, commonly referred to as "Say-on-Pay" (see Proposal No. 2). Accordingly, we are requesting your advisory vote this year to determine whether future Say-on-Pay votes should be held annually, every two years or every three years. The Company currently holds Say-on-Pay votes every year.Amended Plan contains other non-substantive and conforming changes.

The ~~Company’s stockholders expressed a strong preference for an annual frequency~~Amended Plan will not result in any increase in the ~~vote held at~~number of shares authorized for issuance thereunder.

We believe equity compensation is a critical tool for employee motivation and retention. We are proposing to extend the ~~2017 Annual Meeting~~duration of ~~Stockholders. Of~~ the ~~shares voted at that meeting (excluding abstentions~~Existing Plan to enable us to continue effectively offering equity compensation to our employees. If the Amended Plan is not approved, the Existing Plan will expire by its terms on February 24, 2025.

PURPOSE AND BACKGROUND

The primary goal of the Amended Plan is to extend the duration of the Existing Plan from February 24, 2025 to February 24, 2030.

If stockholders do not approve the Amended Plan, we will not be able to issue equity-based awards following February 24, 2025 and ~~broker non-votes), approximately 82% voted in favor of an annual vote. The Board continues~~will be solely reliant on cash awards to ~~believe that an annual vote is~~our employees. An inability to grant equity-based awards would have significant negative consequences to the ~~most effective means of ensuring that our executive compensation policies~~Company and ~~procedures are strongly aligned with the interests of~~ our stockholders including the following:

Inhibit Pay for Performance and ~~are effective in implementing~~Alignment with Stockholders. A key element of our compensation philosophy is to pay a meaningful portion of variable compensation in the form of stock-based awards, which we believe aligns employee and in achieving our strategic goals. The Board’s belief is further based on the premise that this recommendation can be modified in future years if it becomes apparent that a vote once every year is not meaningful or a different voting frequency is recommended by best corporate governance practices.stockholder interests and drives long-term value creation.

~~Stockholders should~~Result in Increased Cash Compensation. In order to attract and retain qualified personnel, we would likely be ~~aware that they are~~compelled to alter our compensation programs to increase the cash-based components, which would not ~~voting "FOR" or "AGAINST"~~provide the ~~Board’s recommendation to vote~~same benefits as equity awards and would limit cash available for a frequency of 1 YEAR for future advisory votes on the compensation of our NEOs. Rather, stockholders will be casting votes to recommend that an advisory vote on the compensation of our NEOs be held every year, every other ~~year or every three years, or they may abstain entirely from voting on the matter.~~purposes.

Restrict our Ability to Retain Key Employees. We currently use equity compensation as a primary method for retaining key qualified personnel, including our executive officers. If we are no longer able to offer stock-based compensation, we might be subject to attrition risk from key employees.

In accordance with SEC rules, we have set forth below a stockholder proposal, along with the supporting statement of the stockholder proponent. The stockholder proposal and the supporting statement are included exactly as submitted to us by the stockholder proponent. The proposal may contain assertions about the Company or other matters that the Company believes are incorrect, but the Company has not attempted to refute all of those assertions. The Company disclaims responsibility for the accuracy and content of the stockholder proponent’s proposal and supporting statement. The stockholder proposal is required to be voted on at the Annual Meeting only if properly presented. The name and address of the stockholder proponent is set forth below. As explained below, the Board of Directors unanimously recommends a vote "AGAINST" the stockholder proposal.

We have been advised that Mr. John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, who has represented to us that he has held for at least three years prior to the date of submission of his proposal 50 shares of our common stock, intends to submit the following proposal at the 2023 Annual Meeting:

		~~Proposal 5—Independent Board Chairman~~

		Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary in order that 2 separate people hold the office of the Chairman and the office of the CEO.
		~~Whenever possible, the Chairman of the Board shall be an Independent Director.~~
		The Board has the discretion to select a Temporary Chairman of the Board who is not an Independent Director to serve while the Board is seeking an Independent Chairman of the Board on an accelerated basis.
		~~It is a best practice to adopt this policy soon. However this policy could be phased in where there is a contract renewal for our current CEO or for the next CEO transition.~~

Our stockholders subsequently approved the reservation of an additional 1,500,000 shares of our common stock in 2020.

No awards have been granted or promised with respect to the Amended Plan. Grants of awards under the Amended Plan remain subject to the discretion of the Compensation Committee in its capacity as plan administrator. Therefore, it is not possible to determine the benefits that will be received in the future by participants in the Amended Plan. Certain tables below under the general heading “Executive Compensation,” including Summary Compensation, Grants of Plan Based Awards, Option Exercises and Stock Vesting, and Outstanding Equity Awards at Fiscal Year-End set forth information with respect to prior awards granted to our individual named executive officers under the Existing Plan.

A Lead Director is no substitute for an independent Board Chairman. According to the Reliance Steel governing documents the RS Lead Director lacks in having exclusive powers. For instance some of the limited duties only require Lead Director approvals, which could be done in the hour before a meeting, and some of these powers are shared with others:

•

~~Approves meeting schedules and agendas for the full Board and the nonmanagement [sic] and independent directors.~~

~~(But could be passive as far as the development of the schedules and agendas.)~~

•

~~Has authority to call meetings of the non-management and independent directors.~~

~~(Other directors can call meetings of some of the independent directors.)~~

•

~~Approves information sent to the Board.~~

~~(But is passive as far as the development of the information.)~~

•

~~Facilities communication between independent directors and management and between independent directors and the full Board.~~

~~(A task shared with others.)~~

~~Plus management fails to give shareholders enough information on this topic to make a more informed decision. There is no comparison for the~~ ~~exclusive powers~~ ~~of the Office of the Chairman and the~~ ~~exclusive powers~~ ~~of the Lead Directors.~~

The ascending complexities of a company with $11 Billion in market capitalization, like Reliance Steel, increasingly demand that 2 persons fill the 2 most important jobs at RS on an enduring basis-Chairman and CEO.

~~Independent Board Chairman—Proposal 5~~

		2024 Proxy Statement ~~in Opposition to Proposal No. 5~~/15
		~~The Board considered Mr. Chevedden’s proposal and, for the reasons described below, believes that the proposal is not in the best interests of the Company and its stockholders.~~
		Reliance has had an independent, non-executive Chairman of the Board since July 2016 and strongly supports the principle of having an independent director in a Board leadership position at all times. In addition, our Principles of Corporate Governance provide that if Reliance does not have an independent Chairman, the Board will elect an independent Lead Director having prescribed duties significantly similar to those of an independent Chairman. Given the Company’s commitment to independent Board leadership, including having an independent, non-executive Chairman for the last seven years, the Board does not believe that adoption of the proposal is necessary or appropriate for the Company or its governance structure.

SUMMARY OF ~~A POLICY~~

~~REGARDING SEPARATION~~MATERIAL TERMS OF THE ~~ROLES OF CHAIRMAN AND CHIEF EXECUTIVE OFFICER~~AMENDED PLAN

The Amended Plan is intended to promote the interests of the Company and its stockholders by providing eligible employees with incentives and rewards to encourage them to continue in the service of the Company or its affiliates. The Amended Plan is designed to serve this goal by providing such individuals with a proprietary interest in pursuing the long-term growth, profitability and financial success of the Company. Our Board believes our capacity to grant equity-based compensation has been a significant factor in our ability to achieve our growth objectives and enhance stockholder value.

The following summary of the material terms of the Amended Plan is qualified in its entirety by reference to the complete text of the Amended Plan, which is attached hereto as Annex A.

Administration

The Amended Plan is administered by the Compensation Committee. To the extent necessary to comply with Rule 16b-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and with respect to certain historical awards that are intended to qualify as “performance based compensation” under Section 162(m) prior to the amendments resulting from the Tax Cuts and Jobs Act of 2017 (“Tax Cuts and Jobs Act”), the Compensation Committee will take all action with respect to such awards and will consist solely of two or more non-employee directors of the Company, each of whom is an “outside director” within the meaning of Section 162(m) and a “non-employee director” within the meaning of the rules under Section 16 of the Exchange Act. In addition, to the extent required by applicable law, each member of the Compensation Committee shall be an “independent director” under the rules of the NYSE (or other principal securities market on which shares of our common stock are traded). The Compensation Committee may delegate to a committee of one or more members of our Board or one or more of our officers the authority to grant or amend awards to participants other than (i) our senior executives who are subject to Section 16 of the Exchange Act, (ii) “covered employees” with respect to awards intended to qualify as “performance based compensation” under Section 162(m) prior to the amendments resulting from the Tax Cuts and Jobs Act, and (iii) officers of the Company to whom the authority to grant or amend awards has been delegated, subject to restrictions imposed by the Compensation Committee from time to time, the Company’s governing documents and applicable law. The Board, Compensation Committee or any delegate thereof, as applicable, are referred to herein as the “plan administrator”.

In addition, adopting the enduring policy requested by the proposal would unduly restrict the Board’s flexibility to determine the optimal leadership structure at any given time. The Board, assisted by the Nominating and Governance Committee, regularly evaluates the size, structure and composition of the Board to ensure that the Board is fulfilling the needs and requirements of the Board both currently and in the future. The Board also undertakes an annual self-assessment to further review the structure and effectiveness of the Board and its leadership, as well as committee assignments and committee member rotations. The Board believes that it is critical to have the flexibility of selecting the structure of leadership best suited to meet the needs of the Company and its stockholders. This enables the Board to tailor its structure to the strengths of the Company’s officers and directors in order to best address the Company’s evolving and complex business. Eliminating this flexibility would be unnecessarily rigid and might also deprive the directors of the ability to select the most qualified and appropriate individual to lead the Board as Chair.16/ 2024 Proxy Statement

investor.reliance.com

TABLE OF CONTENTS

PROPOSAL NO. 4 – AMENDMENT NO. 2 TO THE SECOND AMENDED AND RESTATED 2015 INCENTIVE AWARD PLAN

Unless otherwise limited by the Board, the Compensation Committee will have the authority to administer the Amended Plan with respect to grants of equity awards, including the power to determine eligibility, the types and sizes of awards and the price and timing of awards, as well as the authority to delegate such administrative responsibilities. If the Amended Plan is approved by stockholders, the Compensation Committee will not have the power to accelerate or waive any vesting restriction, other than in the cases of death and disability or a change in control.

Eligibility

Persons eligible to participate in the Amended Plan are, as of March 28, 2024, approximately 15,300 employees of the Company and its subsidiaries, as determined by the Compensation Committee. In 2023, approximately 590 employees received equity awards under the Existing Plan.

Size of Share Pool; Limitation on Awards and Shares Available

The total number of shares reserved for issuance under the Existing Plan is 11,500,000 shares of our common stock as of March 28, 2024. The Amended Plan will not result in any increase in the number of shares authorized for issuance thereunder.

If any shares subject to an award under the Amended Plan are forfeited, expire or are settled for cash, or are converted into shares of another entity in connection with a recapitalization, merger or similar transaction, any shares subject to such award may, to the extent of such forfeiture, expiration, cash settlement or conversion, be used again for new grants under the Amended Plan. However, the following shares may not be used again for grant under the Amended Plan: (1) shares tendered or withheld to satisfy grant or exercise price or tax withholding obligations associated with an option or SAR; (2) shares subject to a SAR that are not issued in connection with the stock settlement of the SAR on its exercise; and (3) shares purchased on the open market with the cash proceeds from the exercise of options.

Awards granted under the Amended Plan in connection with the assumption, replacement, conversion or adjustment of outstanding equity awards in the context of a corporate acquisition or merger will not reduce the shares authorized for grant under the Amended Plan.

The maximum number of shares of our common stock that may be subject to one or more awards granted to any one participant pursuant to the Amended Plan during any calendar year is 500,000 shares and the maximum amount that may be paid under a cash award pursuant to the Amended Plan to any one participant during any calendar year period is $15 million.

Minimum Vesting Provisions

If the Amended Plan is approved by our stockholders, except with respect to a maximum of five percent (5%) of the remaining shares granted with respect to any award under the Amended Plan in the aggregate, any award that vests on the basis of a participant’s continued service may not be granted with vesting conditions under which vesting is any more rapid than vesting on the one (1) year anniversary of the grant date, and any award with performance-based vesting must be granted with a performance period of at least twelve (12) months. (Certain substitute awards that the Company may assume in corporate transactions would not be subject to this provision.) The Compensation Committee may, however, provide for the earlier vesting, exercisability, and/or settlement under any award in the event of a grantee’s death or disability or in connection with a change in control. The minimum vesting provisions would not apply to the payment of dividend equivalent rights settled in cash or dividend equivalent rights settled in shares that are distributed once an underlying award to which the dividend equivalent right relates becomes vested.

Awards

The Amended Plan provides for the grant of stock options, including incentive stock options (“ISOs”) and nonqualified stock options (“NSOs”), SARs, restricted stock, restricted stock units (“RSUs”), dividend equivalents or other stock-based or cash-based awards. Certain awards under the Amended Plan may constitute or provide for a deferral of compensation, subject to Section 409A of the Code, which may impose additional requirements on the terms and conditions of such awards. All awards under the Amended Plan will be set forth in award agreements, which will detail all terms and conditions of the awards, including any applicable vesting and payment terms and post-termination exercise limitations. Awards will generally be settled in shares of our common stock.

investor.reliance.com

Should the best interests of stockholders warrant the appointment of a Chair who is not independent, the Board believes that it must be allowed to take that action in alignment with the exercise of its fiduciary duty. In that case, pursuant to the Company’s Principles of Corporate Governance, the Board’s independent directors would simultaneously appoint an independent Lead Director who would, among other prescribed responsibilities, preside over regular executive sessions of the non-management directors, approve the agenda of each Board meeting, have the authority to call meetings of the non-management directors, approve information sent to the Board, preside at Board meetings at which the Chair is not present, act as the liaison between management and non-management directors and be authorized to engage with major stockholders on the Company’s behalf.

PROPOSAL NO. 4 – AMENDMENT NO. 2 TO THE SECOND AMENDED AND RESTATED 2015 INCENTIVE AWARD PLAN

Stock options. Stock options provide for the purchase of shares of our common stock in the future at an exercise price set on the grant date. ISOs, by contrast to NSOs, may provide tax deferral beyond exercise and favorable capital gains tax treatment to their holders if certain holding period and other requirements of the Code are satisfied. The exercise price of a stock option may not be less than 100% of the fair market value of the underlying share on the date of grant (or 110% in the case of ISOs granted to certain significant stockholders), except with respect to certain substitute options granted in connection with a corporate transaction. The term of a stock option may not be longer than ten years (or five years in the case of ISOs granted to certain significant stockholders). Vesting conditions determined by the plan administrator may apply to stock options and may include continued service, performance and/or other conditions.

Restricted stock units. RSUs are contractual promises to deliver shares of our common stock (or the fair market value of such shares in cash) in the future, which may also remain forfeitable unless and until specified vesting conditions are met. RSUs generally may not be sold or transferred until vesting conditions are removed or expire. The shares underlying RSUs will not be issued until the RSUs have vested, and recipients of RSUs generally will have no voting or dividend rights prior to the time the RSUs are settled in shares, unless the RSU includes a dividend equivalent right (in which case the holder may be entitled to dividend equivalent payments under certain circumstances). Delivery of the shares underlying RSUs may be deferred under the terms of the award or at the election of the participant, if the plan administrator permits such a deferral. On the settlement date or dates, we will issue to the participant one unrestricted, fully transferable share of our common stock (or the fair market value of one such share in cash) for each vested and nonforfeited RSU.

Restricted stock. Restricted stock is an award of nontransferable shares of our common stock that remain forfeitable unless and until specified vesting conditions are met. Vesting conditions applicable to restricted stock may be based on continuing service, the attainment of performance goals and/or such other conditions as the plan administrator may determine. In general, restricted stock may not be sold or otherwise transferred until restrictions are removed or expire. Holders of restricted stock will have voting rights. In addition, if the Amended Plan is approved by our stockholders, dividends which are paid prior to vesting shall only be paid out to the participant to the extent that the performance-based or service based vesting conditions are subsequently satisfied and the share of restricted stock vests.

Stock appreciation rights. SARs entitle their holder, upon exercise, to receive an amount equal to the appreciation of the shares subject to the award between the grant date and the exercise date. The exercise price of a SAR may not be less than 100% of the fair market value of the underlying share on the date of grant (except with respect to certain substitute SARs granted in connection with a corporate transaction) and the term of a SAR may not be longer than ten years. Vesting conditions determined by the plan administrator may apply to SARs and may include continued service, performance and/or other conditions. SARs under the Amended Plan will be settled in cash or shares of common stock, or in a combination of both, as determined by the plan administrator.

Other stock-based or cash-based awards. Other stock based or cash based awards are awards other than those enumerated in this summary that entitle the holder thereof to receive shares or cash immediately or in the future, subject to terms and conditions determined by the plan administrator. Other stock-based or cash-based awards may be linked to any one or more of the performance criteria listed below or other specific performance criteria determined by the plan administrator. Other stock-based or cash-based awards under the Amended Plan will be settled in cash or shares of common stock, or in a combination of both, as determined by the plan administrator, and may be provided as part of a bonus, deferred bonus, deferred compensation or other arrangement and/or as payment in lieu of compensation to which the holder is otherwise entitled.

Dividend equivalents. Dividend equivalents represent the right to receive the equivalent value of dividends paid on shares of our common stock and may be granted alone or in tandem with awards other than stock options or SARs. Dividend equivalents are credited but not paid as of dividend payment dates during the period between the grant date and the date such award terminates or expires, as determined by the plan administrator. Dividend equivalents with respect to shares subject to an award, whether subject to service-based and/or performance-based vesting criteria, will only be paid to the participant at the same time or times and to the same extent that the vesting conditions, if any, are subsequently satisfied and the shares subject to the award vest. Dividend equivalents will not be granted with respect to stock options or SARs.

Performance awards

Any award may be granted as a performance award, meaning that the award will be subject to vesting and/or payment based on the attainment of specified performance goals. For purposes of grants to be made under the Amended Plan, performance criteria used in setting performance goals may include, but are not limited to: (1) net earnings or losses (either before or after one or more of the following: (a) interest, (b) taxes, (c) depreciation, (d) amortization and (e) non-cash

equity-based compensation expense); (2) gross or net sales or revenue or sales or revenue growth; (3) net income (either before or after taxes); (4) adjusted net income; (5) operating earnings or profit (either before or after taxes); (6) cash flow (including, but not limited to, operating cash flow and free cash flow); (7) return on assets; (8) return on capital (or invested capital) and cost of capital; (9) return on stockholders’ equity; (10) total stockholder return; (11) return on sales; (12) gross or net profit or operating margin; (13) operating income (including, but not limited to, growth rate of operating income or compounded annual growth rate of operating income); (14) costs, reductions in costs and cost control measures; (15) expenses including, but not limited to, expenses as a percentage of sales, reductions in expenses and other expense measures; (16) working capital, including without limitation, days sales outstanding and/or inventory turn; (17) earnings or loss per share; (18) adjusted earnings or loss per share; (19) price per share or dividends per share (or appreciation in and/or maintenance of such price or dividends); (20) regulatory achievements or compliance; (21) implementation or completion of critical projects, including, without limitation, acquisitions, divestitures and/or other strategic transactions; (22) market share; and (23) economic value, any of which may be measured either in absolute terms for the Company as a whole or any operating unit of the Company or as compared to any incremental increase or decrease or as compared to results of a peer group or to market performance indicators or indices. The Amended Plan also permits the plan administrator to provide for objectively determinable adjustments to the applicable performance criteria in setting performance goals.

Certain Transactions

The plan administrator has broad discretion to take action under the Amended Plan, as well as make adjustments to the terms and conditions of existing and future awards, to prevent the dilution or enlargement of intended benefits and facilitate necessary or desirable changes in the event of certain transactions and events affecting our common stock, such as stock dividends, stock splits, mergers, acquisitions, consolidations and other corporate transactions. In addition, in the event of certain non-reciprocal transactions with our stockholders known as “equity restructurings,” the plan administrator will make equitable adjustments to the Amended Plan and outstanding awards. In the event of a change in control of the Company (as defined in the Amended Plan), to the extent that the surviving entity declines to assume or substitute outstanding awards or it is otherwise determined that awards will not be assumed or substituted, the plan administrator may cause the awards to terminate in exchange for cash, rights or other property, or become fully vested and exercisable in connection with the transaction. If an award vests and, as applicable, is exercised in lieu of assumption or substitution in connection with a change in control, the award will terminate upon the change in control. In addition, in the event that an award is assumed or substituted in connection with a change in control and the holder is terminated without cause within 12 months following the change in control, such award will become fully vested.

Foreign Participants, Clawback Provisions, Transferability, and Participant Payments

The plan administrator may modify award terms, establish subplans and/or adjust other terms and conditions of awards, subject to the share limits described above, in order to facilitate grants of awards subject to the laws and/or stock exchange rules of countries outside of the United States. All awards will be subject to the provisions of any clawback policy implemented by the Company to the extent set forth in such clawback policy and/or in the applicable award agreement. With limited exceptions for estate planning, domestic relations orders, certain beneficiary designations and the laws of descent and distribution, awards under the Amended Plan are generally non-transferable prior to vesting, and are exercisable only by the participant, unless otherwise provided by the plan administrator. With regard to tax withholding, exercise price and purchase price obligations arising in connection with awards under the Amended Plan, the plan administrator may, in its discretion, accept cash or check, shares of our common stock that meet specified conditions, a “market sell order” or such other consideration as it deems suitable.

Plan Amendment and Termination

Our Board of Directors may amend or terminate the Amended Plan at any time; provided, however, that, except in connection with certain changes in our capital structure, stockholder approval will be required for any amendment that increases the number of shares available under the Amended Plan or the individual award limits discussed above, reduces the price per share of any outstanding stock option or SAR, or cancels any stock option or SAR in exchange for cash or another award when the option or SAR price per share exceeds the fair market value of the underlying shares. In addition, no amendment, suspension or termination of the Amended Plan may, without the consent of the affected participant, impair any rights or obligations under any previously granted award, unless the award itself otherwise expressly so provides. No awards may be granted pursuant to the Amended Plan after February 24, 2030.

Reliance has an empowered independent Board that provides robust and effective oversight. As previously noted, Mark V. Kaminski has served as independent, non-executive Chairman since July 2016. Seven of the nine nominees to the Board, and 100% of each of the Board’s Audit Committee, Nominating and Governance Committee; and Compensation Committee satisfy the independence standards of the New York Stock Exchange (the "NYSE") and other regulatory independence requirements. Moreover, the Board holds executive sessions of its independent directors throughout the year, at each of which the independent Chairman presides.

2024 Proxy Statement /19

TABLE OF CONTENTS

PROPOSAL NO. 4 – AMENDMENT NO. 2 TO THE SECOND AMENDED AND RESTATED 2015 INCENTIVE AWARD PLAN

Material U.S. Federal Income Tax Consequence

The following is a brief description of the principal United States federal income tax consequences related to awards under the Amended Plan. This summary deals with the general federal income tax principles that apply and is provided only for general information. Some kinds of taxes, such as state, local and foreign income taxes and federal employment taxes, are not discussed. This summary is not intended as tax advice to participants, who should consult their own tax advisors.

Non-Qualified Stock Options. For federal income tax purposes, if participants are granted NSOs under the Amended Plan, participants generally will not have taxable income on the grant of the option, nor will the Company be entitled to any deduction. Generally, on exercise of NSOs, participants will recognize ordinary income, and the Company will be entitled to a deduction, subject to the limitations imposed by Section 162(m) of the Code, in an amount equal to the difference between the option exercise price and the fair market value of the common stock on the date of exercise. The basis that participants have in shares of common stock, for purposes of determining their gain or loss on subsequent disposition of such shares of common stock generally, will be the fair market value of the shares of common stock on the date the participants exercise their options. Any subsequent gain or loss will be generally taxable as capital gains or losses.

Incentive Stock Options. There is no taxable income to participants when participants are granted an ISO or when that option is exercised. However, the amount by which the fair market value of the shares of common stock at the time of exercise exceeds the option price will be an “item of adjustment” for participants for purposes of the alternative minimum tax. Gain realized by participants on the sale of an ISO is taxable at capital gains rates, and no tax deduction is available to the Company, unless participants dispose of the shares of common stock within (i) two years after the date of grant of the option or (ii) within one year of the date the shares of common stock were transferred to the participant. If the shares of common stock are sold or otherwise disposed of before the end of the one-year and two-year periods specified above, the difference between the option exercise price and the fair market value of the shares of common stock on the date of the option’s exercise (or the date of sale, if less) will be taxed at ordinary income rates, and the Company will be entitled to a deduction, subject to the limitations imposed by Section 162(m) of the Code, to the extent that participants must recognize ordinary income. If such a sale or disposition takes place in the year in which participants exercise their options, the income such participants recognize upon sale or disposition of the shares of common stock will not be considered income for alternative minimum tax purposes.

ISOs exercised more than three months after a participant terminates employment, other than by reason of death or disability, will be taxed as a NSO, and the participant will have been deemed to have received income on the exercise taxable at ordinary income rates. The Company will be entitled to a tax deduction, subject to the limitations imposed by Section 162(m) of the Code, equal to the ordinary income, if any, realized by the participant.

Other Awards. The current federal income tax consequences of other awards authorized under the Amended Plan generally follow certain basic patterns: SARs are taxed and deductible in substantially the same manner as NSOs; nontransferable restricted stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value over the price paid, if any, only at the time the restrictions lapse (unless the recipient elects, with our approval, to accelerate recognition as of the date of grant); RSUs, stock-based performance awards and other types of awards are generally subject to income tax at the time of payment, vesting or settlement based on the fair market value of the award on that date. Compensation otherwise effectively deferred will generally be subject to income taxation when paid. In each of the foregoing cases, the Company will generally have a corresponding deduction at the time the participant recognizes income, subject to the limitations imposed by Section 162(m).

Section 162(m) of the Code

Section 162(m) of the Code denies a deduction to any publicly held corporation for compensation paid to certain “covered employees” in a taxable year to the extent that compensation to such covered employee exceeds $1 million. As a result of the Tax Cuts and Jobs Act, which became effective January 1, 2018, Section 162(m) of the Code no longer provides an exception for public companies to exceed the $1 million limit on the deduction for executive compensation paid to certain executive officers when the compensation is qualified as “performance-based compensation”. The changes under Section 162(m) of the Code are generally effective for taxable years beginning in 2018, but there is a grandfather rule for compensation paid pursuant to a written, binding contract that was in effect on November 2, 2017, which was not modified in any material respect on or after that date. It is possible that compensation attributable to awards under the Amended

Plan, when combined with all other types of compensation received by a covered employee from us, may cause the $1 million deduction limitation to be exceeded in any particular year.

Section 409A of the Code

Certain types of awards under the Amended Plan may constitute, or provide for, a deferral of compensation subject to Section 409A of the Code. Unless certain requirements set forth in Section 409A of the Code are complied with, holders of such awards may be taxed earlier than would otherwise be the case (e.g., at the time of vesting instead of the time of payment) and may be subject to an additional 20% penalty tax (and, potentially, certain interest penalties and additional state taxes). To the extent applicable, the Amended Plan and awards granted under the Amended Plan are intended to be structured and interpreted in a manner intended to either comply with or be exempt from Section 409A of the Code and the Treasury regulations and other interpretive guidance that may be issued under Section 409A of the Code. To the extent determined necessary or appropriate by the plan administrator, the Amended Plan and applicable award agreements may be amended to further comply with Section 409A of the Code or to exempt the applicable awards from Section 409A of the Code.

	investor.reliance.com			The proponent states that the proposal could be phased in upon a contract renewal for our current CEO or for the next CEO transition. As described in this proxy statement, however, none of the Company’s executive officers, including the CEO, has an employment agreement and Karla R. Lewis became Reliance’s President and Chief Executive Officer on January 1, 2023.
		The stockholder proposal is unnecessary given the Company’s seven-year history with an independent board chair and the proven framework the Board has in place to ensure independent leadership for the Board at all times. Adoption of the proposed static policy could restrict the Board’s decision-making ability and limit the options available to the Board in structuring effective leadership; accordingly, the Board recommends a vote "AGAINST" this Proposal No. 5.	2024 Proxy Statement /21

Our tons sold, average selling price per ton sold and Tons Sold Growth (as defined below) exclude tons toll processed.

Gross profit, calculated as net sales less cost of sales, and gross profit margin, calculated as gross profit divided by net sales, are non-GAAP financial measures as they exclude depreciation and amortization expense associated with the corresponding sales. About half of Reliance’s orders are basic distribution with no processing services performed. For the remainder of its sales orders, Reliance performs ~~"first-stage"~~“first-stage” processing, which is generally not labor intensive as it is simply cutting the metal to size. Because of this, the amount of related labor and overhead, including depreciation and amortization, is not significant and is excluded from cost of sales. Therefore, Reliance’s cost of sales is substantially composed of the cost of the material it sells. Reliance uses gross profit margin as shown above as a measure of operating performance. Gross profit margin is an important operating and financial measure, as fluctuations in our gross profit margin can have a significant impact on Reliance’s earnings. Gross profit margin, as presented, is not necessarily comparable with similarly titled measures for other companies.

In 2023, our earnings per diluted share of $22.64 and operating cash flow of $1.67 billion were the second highest in our history, surpassed only by the records set in 2022 due to a very favorable metals pricing environment.

Tons sold increased 3.7% in 2023 compared to 2022 due to healthy demand in our key end markets, including non-residential construction (our largest end market), automotive and aerospace, as well as contributions from our organic growth activities. The increase in our tons sold in 2023 significantly outperformed the 1.5% increase in shipments for the industry as reported by the Metals Service Center Institute (“MSCI”), while maintaining our gross profit margin at 30.7%, which was towards the high end of our estimated 29% to 31% sustainable range.

Our net sales of $14.81 billion declined 13.0% in 2023 compared to record levels of $17.03 billion in 2022 due to a decline in our average selling price per ton sold of 16.4% that was partially offset by an increase in our tons sold.

We believe record metals pricing in 2022 was largely driven by supply chain disruptions caused by the onset of the conflict between Russia and Ukraine, labor supply and microchip shortages, and impacts of the COVID-19 pandemic, including the omicron variant surge and lockdowns in China.

We continued to execute our balanced capital allocation strategy in 2023 using cash flow from operations to return $717.6 million to our stockholders through $238.1 million of record dividends and $479.5 million of share repurchases. In addition, we continued to fund organic growth by investing $468.8 million in capital expenditures. We also invested in our growth in 2023 by acquiring Southern Steel Supply, LLC which aligns with our business model and disciplined strategy of investing in profitable, high-quality businesses that expand our geographic diversity and value-added processing capabilities.

During 2023, we repurchased approximately 1.9 million shares of our common stock at an average cost of $255.30 per share, or $479.5 million in total.

We paid a total of $238.1 million in dividends to our stockholders in 2023. In February 2024, we increased our regular quarterly dividend 10% to $1.10 per share from $1.00 per share.

~~COMPENSATION DISCUSSION AND ANALYSIS~~

~~Changes to 2022 Annual Cash Incentive Plan~~

~~In July 2021, the~~Executive Compensation Committee, in consultation with Pay Governance, LLC ("Pay Governance"), the Compensation Committee’s independent executive compensation advisor, and with input from management, determined that it would be in the best interests of the Company’s stockholders to update the metrics used to measure the Company’s financial performance under the annual cash incentive plan beginning with the 2022 annual cash incentive awards.

From 2016 to 2021, the Company employed Pretax Income Margin as the sole financial metric used to measure performance under the annual cash incentive plan. The Compensation Committee continues to believe that Pretax Income Margin is an important and useful metric that aligns the NEOs’ annual cash incentive opportunities with the Company’s financial performance. Starting in 2022, however, the Company added the percentage growth in tons of metal sold ("Tons Sold Growth") as an additional metric under the annual cash incentive plan. Tons Sold Growth was selected as a performance metric by the Compensation Committee because it is a key performance indicator used by the Board and management to measure and evaluate one of the important underlying performance elements of the Company’s business. The Compensation Committee believes Tons Sold Growth complements and achieves an appropriate balance with the Pretax Income Margin metric, and when combined, both metrics motivate profitable growth. Tons Sold Growth is calculated consistent with our financial reporting and excludes toll processed tonnage.

As in past years, the target annual cash incentive opportunity in 2022 for each NEO remained 150% of their base salary subject to achievement of prescribed targets. Achievement of the targets was divided between achievement of the Tons Sold Growth target (10% portion of annual cash incentive, or 15% of base salary) and the Pretax Income Margin targets (90% portion of annual cash incentive, or 135% of base salary).

For 2022, the Compensation Committee set the portion of the target annual cash incentive award to be earned based upon Tons Sold Growth at 15.0% of base salary, which amount would be earned if Tons Sold Growth was 2.00%. The maximum award of 30.0% of base salary would be earned if Tons Sold Growth equaled or exceeded 4.00%. No payment under the Tons Sold Growth metric would be made if the Company’s tons sold declined year-over-year. Mathematical interpolation is applied to determine the actual incentive award for any Tons Sold Growth that is less than 4.0% (threshold to target or target to maximum.)

The remaining portion of the total annual cash incentive opportunity at target level, or 135% of base salary for each NEO, would be earned based on Pretax Income Margin. The Compensation Committee made the Pretax Income Margin targets more demanding in 2022 by raising the prescribed Pretax Income Margin goals. The target award of 135% of base salary would be earned if Pretax Income Margin was 6.00% (up from 5.75% and down from 150% of base salary in 2021), which would have placed the Company near the 41st percentile of historical Pretax Income Margin performance in its executive compensation peer group in 2022. No payment would be made if Pretax Income Margin was less than 3.50% (up from 3.00% in 2021), which would have placed the Company at approximately the 25th percentile of Pretax Income Margin performance in its executive compensation peer group. The maximum award of 270.0% of base salary would be earned if Pretax Income Margin equaled or exceeded 9.00% (up from 8.50% in 2021), which would have placed the Company at the 61st percentile of Pretax Income Margin performance in its executive compensation peer group.

interests of our stockholders. Our stockholders have been highly supportive of our program’s pay-for-performance structure as demonstrated by our say-on-pay voting results exceeding ~~96%~~90% in each of the last five years from ~~2018~~2019 through ~~2022.~~2023.

As described in more detail below, we structure our executive officers’ target total direct compensation to be competitive with the median compensation paid by companies with whom we may compete for executive talent, including those in our executive compensation peer group. We ~~link a~~tie the substantial majority of our executives’ compensation to Company performance objectives to drive ~~our~~ financial and operating performance and ~~maximize~~reward executives for delivering stockholder value. We believe that this pay-for-performance philosophy has been instrumental to our success.

We manage our business with the long-term objective of creating and maximizing value for our stockholders. Our pay-for-performance philosophy is aligned with and supports this objective.

Consistent with our past practice, the Compensation Committee evaluates performance by reviewing:

•

our operating and financial results, including performance against our executive compensation peer group, our industry peers, and general economic factors that impact our business and industry;

•

economic return to stockholders over time, both on an absolute basis and relative to other companies, including the S&P 500, our executive compensation peer group and our industry peers; and

•

achievement of the Company’s goals and objectives (including management development and succession, safety performance, working capital management, growth in profitability and volume, and capital allocation).

The Compensation Committee has linked a substantial majority of our executives’ total direct compensation directly to the achievement of specific, pre-established Company performance targets. In ~~2022,~~2023, approximately 74% of our CEO’s and ~~70%~~71% of our other NEOs’ target total direct compensation was tied to performance targets.

~~RELATIONSHIP BETWEEN PAY AND PERFORMANCE~~Relationship Between Pay and Performance

AThe majority of our ~~executive~~executives’ compensation is tied to performance through annual cash incentive awards and long-term equity incentive awards. Management once again delivered industry-leading operating results in ~~2022,~~2023, with sales, diluted earnings per share and the Company achieved multiple records, including record annual net sales of $17.03 billion, record gross profit of $5.25 billion, record pretax income and margin of $2.43 billion and 14.3%, record annual EPS of $29.92 and record annual cash flow from operations ~~of $2.12 billion. Our record profitability~~being the second highest results in 2022 was primarily driven by record metals prices, which have been at historically elevated levels in recent years. Additionally, our safety performance was our best ever and lower than the MSCI. Accordingly, we believe compensation of our NEOs in 2022 was aligned with the Company’s ~~2022 operational and financial performance.~~history.

Annual Cash Incentive Award Plan

Consistent with the delivery of industry-leading ~~and record~~ results in ~~2022,~~2023, each NEO received payments at the maximum level under our annual cash incentive plan related to both the Pretax Income Margin and ~~above the threshold but less than the target under the~~ Tons Sold Growth ~~metric,~~metrics, resulting in a total payout equal to ~~283.5%~~300.0% of base salary for each NEO. ~~Each NEO also received the maximum number~~

of performance-based equity awards for the three-year performance RSU measuring period between January 1, 2020 and December 31, 2022, resulting in total performance shares earned at 200.0% of the target.

Our annual cash incentive plan provides NEOs an opportunity to receive annual cash incentive awards based on the Company’s annual performance. The incentive opportunity is expressed as a percentage of base salary.

For ~~2022,~~2023, 90% of the award opportunity available under the annual cash incentive plan was based on the Company’s Pretax Income Margin and 10% of the award opportunity was based on Tons Sold Growth. In ~~2022,~~2023, the target allocation of the cash incentive award between the two separate performance metrics was as follows:

COMPENSATION DISCUSSION AND ANALYSIS

As in ~~past~~prior years, the NEOs’ total target annual cash incentive opportunity in ~~2022 for each NEO~~2023 was 150% of ~~their~~ individual base salary if the targets were achieved. Of this amount, 135% of base salary would be received based upon achievement of the target Pretax Income Margin goal, and 15% of base salary would be received based upon achievement of the target Tons Sold Growth goal.

~~The Compensation Committee made the Pretax Income Margin targets more demanding~~As in 2022, ~~by raising~~ the ~~prescribed Pretax Income Margin goals. The~~ Pretax Income Margin portion of the ~~2022~~2023 annual cash incentive plan opportunity was established on a sliding scale, ranging from zero for results below the 3.50% Pretax Income Margin threshold, 20% of base salary for results at the 3.50% Pretax Income Margin threshold, a target of 135% of base salary at 6.00% Pretax Income Margin up to a maximum of 270% of base salary for Pretax Income Margin of 9.00% or higher. If the Company achieved a Pretax Income Margin within the range of 3.50% and 9.00%, then mathematical interpolation would be applied to determine the actual incentive award in the applicable range (threshold to target or target to maximum).as follows:

	2023 Pretax Income Margin		2023 Performance Award (% of Base Salary)		2022 Pretax Income Margin		2022 Performance Award (% of Base Salary)

~~2022~~2023 Pretax Income Margin (calculated in accordance with our annual cash incentive plan) was ~~14.3%~~11.7%, which resulted in each NEO receiving the maximum award under the portion of the ~~2022~~2023 annual cash incentive plan related to Pretax Income Margin equal to 270% of base salary.

For ~~2022,~~2023, the Compensation Committee, ~~set threshold, target~~in consultation with Pay Governance, LLC (“Pay Governance”), the Compensation Committee’s independent executive compensation advisor, and ~~maximum~~with input from management, determined that it would be in the best interests of the Company and its stockholders to determine achievement of the Tons Sold Growth ~~levels~~metric based on performance as measured against the total tons of metal sold by the U.S. metals service center industry as published by the MSCI (the “MSCI Benchmark”), as follows:

Maximum	2.0% in excess of MSCI Benchmark		30.0%

The Tons Sold Growth portion of the ~~2022~~2023 annual cash incentive plan opportunity was established on a sliding ~~scale, ranging from zero for no growth in~~scale. For 2023, the Compensation Committee set the portion of the target annual cash incentive award to be earned based upon tons sold ~~15%~~at 15.0% of base salary, ~~for results at~~which amount would be earned if tons sold exceeded the ~~2.00% Tons Sold Growth target, and up to a~~MSCI Benchmark by 1.0%. The maximum award of ~~30%~~30.0% of base salary ~~for Tons Sold Growth of 4.00% or higher.~~would be earned if tons sold exceeded the MSCI Benchmark by 2.0%. No payment under the tons sold metric would be made if the Company’s tons sold underperformed the MSCI Benchmark. Mathematical interpolation iswould be applied to determine the actual incentive award for ~~any Tons Sold Growth that is less than 4.0% (threshold~~tons sold in excess of the MSCI Benchmark up to ~~target or target to maximum)~~the maximum of 2.0%.

The MSCI Benchmark was used to measure the Tons Sold Growth metric for the first time in 2023. In 2022, the Tons Sold Growth metric was measured as the year-over-year percentage increase in the Company’s tons sold (no payout for a decline, payout of 15.0% for growth of 2.00% and a maximum payout of 30.0% for growth that equaled or exceeded 4.00%), with mathematical interpolation applied to determine the actual incentive award in the applicable range.

The Compensation Committee, in consultation with Pay Governance and with input from management, selected Pretax Income Margin and Tons Sold Growth as the performance metrics for the annual cash incentive opportunity for ~~2022.~~2023. The Compensation Committee selected Pretax Income Margin because it aligns with how management and the Board measure the Company’s performance and is typically one of the most important metrics used in the Company’s corporate and operational decision-making. Tons Sold Growth was selected as a second performance metric by the Compensation Committee because it ~~is a key performance indicator used by the Board and management to measure and evaluate one of the important underlying performance elements of~~promotes growth, compares the Company’s ~~business and because it motivates profitable growth~~performance against an industry indicator, and complements and achieves an appropriate balance with the Pretax Income Margin metric.

Long-Term Equity Incentive Compensation Plan

The NEOs’ performance-based equity awards are tied to achieving an ROA target over a three-year measurement period. The Compensation Committee has determined that a three-year ROA measurement period, which is directly influenced by management’s decisions, is an effective metric to measure management’s long-term performance. ROA also complements and achieves an appropriate balance with the one-year Pretax Income Margin and Tons Sold Growth metrics under the annual cash incentive award program by holding management responsible for the efficient use of ~~the~~ assets ~~used~~ to produce growth and operating profits over a multi-year period. The issued and outstanding ~~2021,~~ 2022, 2023 and ~~2023~~2024 performance-based equity awards will vest if the Company achieves an ROA result at or above a minimum threshold over the applicable three-year performance ~~periods.~~periods, subject to a prescribed maximum.

The allocation of performance-based and service-based equity awards is intended to balance performance and retention objectives. In striking the appropriate balance, the Compensation Committee sought to design a program that incentivizes strong performance while also strengthening the retention aspects of the long-term equity awards since the Company does not maintain employment agreements with its officers. Accordingly, ~~from 2017 through 2021, 80% of our CEO and President’s target equity awards and 60% of our other NEOs’ target equity awards were performance-based. In~~in 2022 and 2023, 80% of all NEO target equity awards issued were performance-based and the remaining awards were service-based, reinforcing the performance orientation of the Company’s compensation program. As discussed under “Changes to 2024 Incentive Plans” below, the Compensation Committee increased the applicable ROA targets and changed the allocation of performance-based and service-based equity awards for certain of the NEOs for the 2024 performance-based equity awards.

Results for the performance-based equity awards granted in ~~2020~~2021 were determined in the first quarter of ~~2023~~2024 based on the Company’s ROA in the three-year measurement period from January 1, ~~2020~~2021 through December 31, ~~2022.~~2023. The Company’s ROA in the three-year measurement period was ~~18.8%~~21.4%, which is in excess of the maximum payout and resulted in the maximum number of awards vesting, or 200% of the target. ~~The three-year measurement period ended December 31, 2022, was the second time since 2008 in which the maximum payout of the performance-based equity awards was achieved.~~

OVERVIEW OF OUR EXECUTIVE COMPENSATION PROGRAM

Compensation Program Objectives

Our compensation program is designed and managed to align executive compensation with Company performance, to motivate our executives to deliver financial and operating results that create and maximize value for our stockholders, and to attract and retain key executive talent. While the Compensation Committee has structured individual components of pay to vary from market medians, it aims for our NEOs’ total compensation to approximate the market median when performance targets are achieved. We believe it is important that our executive compensation program:

•

Aligns the interests of our executives with those of our stockholders. We align the financial interests of our executive officers with the interests of our stockholders by tying athe majority of our executives’ incentive compensation directly to Company performance. In addition, we have implemented significant stock ownership requirements for our executive officers to strengthen the alignment of their interests and our stockholders’ interests.

•

Promotes and maintains a performance- and achievement-oriented culture. In ~~2022,~~2023, approximately 74% of our CEO’s and ~~70%~~71% of our other NEOs’ target total direct compensation was tied to performance metrics. We establish performance targets that are demanding, support our strategic and financial objectives, and promote long-term stockholder value, without encouraging unnecessary or excessive ~~risk taking.~~risk-taking.

•

Is competitive. Our program is designed to attract, retain and motivate talented and skilled executives. As such, we structure total direct compensation at target to be competitive with the median compensation paid by companies with whom we may compete for executive talent, including those in our executive compensation peer group. While individual components of

pay may vary from market medians, we aim to approximate total pay at market median when performance targets are achieved.

The Company enjoys a team-oriented corporate culture and rewards the entire team of corporate officers for their collaborative effort that is reflected in the Company’s industry-leading performance. Attracting and retaining a team of outstanding corporate officers with complementary skills and expertise has proven successful for the Company’s growth, both organically and through acquisitions, and for maintaining the Company’s profitable financial performance, each of which enhances stockholder value. In order to promote our team culture, the Compensation Committee considers internal pay equity when setting compensation levels for our executives. This team approach is best illustrated by our annual cash incentive award program in which all NEOs have the same target annual cash incentive award opportunity (150% of their respective base salaries) based on the same performance objectives. Moreover, equity awards for NEOs are also comparable, with the exception of the President and CEO, the CFO and the COO.

~~ALLOCATION OF COMPENSATION COMPONENTS~~Allocation of Compensation Components

~~We compensate our~~Our executive officers ~~by using~~are compensated with a balanced combination of the elements described above that vary by:

•

type of compensation (fixed, variable, service-based and performance-based);

•

with respect to performance-based compensation, length of the performance period (annual and long-term);

•

form of compensation (cash and equity); and

•

with respect to equity compensation, performance-based and service-based.

We believe this balanced allocation supports our compensation objectives, including alignment of our executives’ and our stockholders’ interests, the retention of our key executives, mitigation of excessive risk taking and appropriate emphasis of pay-for-performance. The Compensation Committee has designed the overall compensation program to ensure that athe majority of our executives’ compensation is ~~at risk and weighted towards Company performance,~~subject to the Company’s annual and long-term ~~incentives and~~performance as well as stock price appreciation. Although a significant majority of our NEOs’ compensation is tied to Company performance, the Compensation Committee has no pre-determined mix or allocation among the various elements. The following chart illustrates the targeted allocation of the principal compensation components for our NEOs in ~~2022.~~2023. The percentages reflect ~~2022~~the NEOs’ 2023 salaries and target annual cash incentive compensation, ~~and~~as well as the ~~aggregate~~ grant date fair values of both service-based RSUs and the target number of performance-based RSUs granted in ~~2022.~~2023.

Mix of Principal Compensation Components

TOTAL PAY MIX AT TARGET RESULTS

HOW WE MAKE DECISIONS REGARDING EXECUTIVE COMPENSATION

Compensation Committee and Independent Directors

The Compensation Committee, which is composed entirely of independent directors, oversees our executive compensation program. ~~Compensation for the NEOs~~NEO compensation is subject to final approval by the independent directors of the Board upon recommendation of the Compensation Committee.

Each year, the independent directors of the Board review and evaluate the CEO’s performance. The Compensation Committee and the independent directors of the Board incorporate the CEO’s performance review —– along with other data including the Company’s financial results, achievement of the Company’s goals and objectives in the past year and the proposed objectives for the coming year —– into their analysis of the CEO’s total compensation and their consideration of the appropriate mix and structure of the elements of the CEO’s total compensation.

At the request of the independent directors, our CEO annually provides a review and evaluation of each of the executive officers, including the NEOs (other than the CEO), identifying accomplishments in the past year, achievement of objectives and results, executive development and proposed objectives for the coming year. The Compensation Committee incorporates the CEO’s reviews of the other NEOs, along with other data including the Company’s financial results and other achievements, into its analysis of the other NEOs’ total compensation and its consideration of the appropriate mix and structure of the elements of the other NEOs’ total compensation.

The Compensation Committee also reviews data provided by its independent compensation consultant, ~~in determining the total compensation,~~Pay Governance, as well as the appropriate mix and structure of the various elements of total compensation, in determining the total compensation of the CEO and the other NEOs. Although base salaries, annual cash incentive awards and long-term incentive awards are considered at different times throughout the year, the Compensation Committee analyzes the proposed total direct compensation package (or the total of base salary, annual cash incentive and long-term incentives) before making any recommendations regarding individual elements of compensation. The Compensation Committee formulates preliminary recommendations on the amount and type of compensation to be paid to the CEO and the other NEOs. The Compensation Committee then discusses with the CEO its preliminary recommendations with respect to the NEOs (other than the CEO). The Compensation Committee presents its final recommendations to the independent directors in executive session and the independent directors make the final determination of and approve the compensation paid to the CEO and the other NEOs.

To ensure that the NEOs and our other executive officers are compensated in a manner consistent with our strategy, competitive market practices, sound corporate governance principles and stockholder interests, the Compensation Committee regularly evaluates our executive compensation program. When doing so, the Compensation Committee

considers the needs of the business, peer practices, external trends and the results of our annual say-on-pay vote. The Compensation Committee also seeks advice from its independent compensation consultant, as well as input from executive management.

Independent Compensation Consultant

The Compensation Committee annually engages an independent compensation consultant to assist it in connection with the review and evaluation of the total compensation package provided to the NEOs and the individual elements thereof. In ~~2022,~~2023, the Compensation Committee engaged Pay Governance as its independent compensation consultant. Pay Governance reports directly to the Compensation Committee and neither it nor any of its affiliates provided any services to the Company, other than the services to the Compensation Committee with respect to executive compensation and the Nominating

and Governance Committee with respect to reviews of our director compensation, which the Board believes does not interfere with the independence of the consultant. The Compensation Committee conducted an assessment of Pay Governance’s independence, taking into account the factors specified in the NYSE listing standards as well as information provided by Pay Governance, and based on that assessment, determined that Pay Governance is independent.

Compensation Committee Review of Executive Compensation Peer Group and Other Data

When making decisions regarding the compensation of our NEOs, the Compensation Committee considers information from a variety of sources. The Compensation Committee analyzes both the individual elements and the total compensation package for each of the NEOs, as well as the relationship of those packages among the NEOs.

Together with its independent compensation consultant, the Compensation Committee reviews our financial statements and compares our financial results with those of both our executive compensation peer group and our industry peer group, as well as other factors specifically impacting the metals industry, and compares compensation information for our NEOs with that available for comparable executives. In determining each executive’s total compensation package, the Compensation Committee considers both qualitative and quantitative criteria, as well as the CEO’s recommendations and performance evaluations and historical compensation records of the Company. Although a significant majority of compensation is tied to Company performance, the Compensation Committee has no pre-determined mix or allocation among the various elements.

The Compensation Committee annually reviews and, as appropriate, revises the executive compensation peer group in an effort to assure the group continues to reflect any changes in the Company’s business, strategy and size as measured by revenue, stock market capitalization and other factors. The Compensation Committee also considers additional factors such as the Company’s stock performance as compared with standard indices, such as the S&P 500, as well as our industry peer group. The Compensation Committee reviews the issued and outstanding but unvested equity awards and common stock actually held by each NEO and recognizes that the NEOs are directly impacted by the Company’s stock price and, accordingly, their interest in the Company’s performance and the impact it has on the market value of the Company’s stock is closely aligned with that of the Company’s stockholders.

The combination of these analyses helps the Compensation Committee assess how our NEOs are compensated compared to their peers —– both in terms of individual components and total compensation, the reasonableness of the Company’s incentive plan goals, the alignment of pay and performance, the potential need for recalibration of the Company’s pay and incentive goals, and the actual elements of NEO compensation.

Executive Compensation Peer Group

There are no public companies in the metals service center industry that are closely comparable to the Company in terms of size, stock market capitalization, complexity and financial performance. Accordingly, in considering executive compensation for ~~2022,~~2023, as in prior years, the Compensation Committee and the independent compensation consultant used the executive compensation peer group set forth below.

The Compensation Committee, with ~~assistance~~input from executive management and the independent compensation consultant, annually reviews specific criteria and recommendations regarding companies to add or remove from the peer group to ensure that the companies in the peer group remain relevant and provide meaningful compensation comparisons. The Compensation Committee strives to maintain consistency in the peer group from year-to-year and only makes changes when appropriate in consultation with ~~the independent compensation consultant~~Pay Governance and executive management.

The executive compensation peer group has been constructed, in part, such that the Company’s revenues, stock market capitalization, enterprise value and invested capital generally approximate the median of the executive compensation peer group companies. However, the industrial and manufacturing companies in this peer group are not impacted at all, or are affected to a lesser degree than Reliance, by fluctuations in metal pricing.

For fiscal year 2023, the peer group was updated to remove ATI Inc., MRC Global Inc. & Terex Corporation and to add Alcoa Corporation, Cleveland-Cliffs Inc. and Westinghouse Air Brake Technologies Corporation. ATI Inc., MRC Global Inc. & Terex Corporation were removed because their lower revenues compared to the Company fell below our peer group methodology parameters. Alcoa Corporation, Cleveland-Cliffs Inc. and Westinghouse Air Brake Technologies Corporation were added to our peer group based on their fit as industrial companies with revenues broadly comparable to the Company.

Analysis of ~~2022~~2023 Company and Executive Compensation Peer Group Compensation

In ~~2022,~~2023, the Compensation Committee reviewed the Company’s financial statements and stock performance in comparison to the peer group’s most currently available financial and stock market data. Consistent with the Company’s pay-for-performance philosophy, ~~of pay-for-performance,~~ the Compensation Committee also considered the total direct compensation (base salary, annual cash incentive award and equity awards) and retirement plan benefits of the NEOs as compared to comparable officers in the executive compensation peer group.

Compared to the executive compensation peer group (based on each peer group member’s most recently released annual financial statements):

•

the Company ranked at the ~~59th~~38th percentile for revenues in ~~2022;~~2023;

•

the Company’s Pretax Income Margin ranked at the ~~69th~~54th percentile in ~~2022;~~2023; and

•

the Company’s return on total assets ranked at the ~~85th~~71st percentile in ~~2022~~2023 and ~~81st~~80th percentile for the five-year period ended December 31, ~~2022.~~2023.

Based on information provided by the independent compensation consultant, the Compensation Committee determined that in ~~2022~~2023 the target total direct compensation ofof: (i) our ~~former~~ CEO approximated the ~~50th~~35th percentile of the chief executive officers in our executive compensation peer ~~group,~~group; (ii) our CFO approximated the 25th percentile of the chief financial officers in our executive compensation peer group; and (iii) the ~~aggregate~~ target total direct compensation of our other NEOs fell between the 50th and ~~75th percentile~~67th percentiles of the comparable executive officers in our executive compensation peer group.

Internal Pay Equity

The Compensation Committee broadly considers internal pay equity when setting compensation levels for our executives in order to foster a team culture among the executive officers. Our executive compensation program uses the same compensation components for all of our NEOs, with a few exceptions. From 2017 through 2021, 80% of our CEO and President’s target long-term equity incentive awards were performance-based RSUs and the remaining 20% were service-based RSUs, while the other NEOs received 60% of their long-term equity incentive awards in performance-based RSUs and the remaining 40% in service-based RSUs.

COMPENSATION DISCUSSION AND ANALYSIS

PRINCIPAL COMPONENTS OF OUR EXECUTIVE COMPENSATION PROGRAM

Base Salary

The base salary payable to each of our NEOs is the minimum compensation that such executive receives in any year. Base salaries reflect the individual skills, experience and roles and responsibilities of the NEO within the Company.

The Compensation Committee reviews NEO salaries annually and makes adjustments to reflect merit, promotion or change in role and changes in market salaries for similar positions.

In July ~~2022,~~2023, after a review of the base salaries of comparable officers at companies in our executive compensation peer group and in consultation with the independent compensation consultant, the Compensation Committee recommended, and the independent directors of the Board approved, base salary increases for the ~~NEOs:~~NEOs as follows: 4.2% for Mrs. Lewis; ~~4.5%~~4.3% for Mr. ~~Ajemyan~~Durham and ~~4.2%~~2.4% for Mr. Smith. In ~~connection with his appointment to the position of Executive Vice President and Chief Operating Officer in July 2022,~~addition, Mr. Koch’s base salary was increased ~~10.0%.~~by 9.1% and Mr. ~~Hoffman did not receive an increase in his~~Ajemyan’s base salary increased 17.4% in ~~2022.

~~The~~ Consistent with our historical pay practices, even after these adjustments, base salaries as a percentage of our NEOs ~~are designed to approximate~~target compensation were below the ~~market median of salaries paid~~25th percentile compared to comparable officers ~~at companies~~ in our executive compensation peer group.

We do not have employment agreements with any of our executive officers. No executive officer has a minimum base salary or guaranteed salary increase.

Annual Cash Incentive Awards

In ~~2022,~~2023, the Compensation Committee employed Pretax Income Margin and Tons Sold Growth as the metrics for measuring the Company’s financial performance under the annual cash incentive plan. The Compensation Committee selected Pretax Income Margin because it aligns with how management and the Board measure the Company’s performance and is typically one of the most important metrics used in the Company’s corporate and operational decision-making. ~~The Compensation Committee included Tons Sold Growth as an additional metric under the annual cash incentive plan in 2022.~~ Tons Sold Growth was selected as a performance metric by the Compensation Committee because it is a key performance indicator used by the Board and management to measure and evaluate one of the important underlying performance elements of the Company’s business. Tons Sold Growth is calculated consistent with our financial reporting and excludes the Company’s toll processing tonnage. The Compensation Committee believes that Tons Sold Growth is a key performance indicator used by the Board and management to measure and evaluate one of the important underlying performance elements of the Company’s business against the Company’s industry peers and because it motivates growth and complements and achieves an appropriate balance with the Pretax Income Margin ~~metric, and when combined, both metrics motivate profitable growth.~~metric.

In 2023, target annual cash incentive opportunities compared to similar executives of companies in our executive compensation peer group approximate: (i) the 25th percentile for our President and CEO (reflecting her promotion into the CEO role); and (ii) the 60th percentile for our other NEOs in aggregate.

In concert with the Company’s compensation philosophy of overweighting performance-based pay, our NEOs have annual cash incentive opportunities that may result in higher cash payments than those for comparable officers within our executive compensation peer group, but such awards are only payable if the Company meets demanding objectives.

This structure currently results in total target cash ~~compensation near~~compensation: (i) that approximates the ~~median~~25th percentile for our ~~former~~ CEO (reflecting her 2023 promotion into the CEO role) and between the 25th percentile and 50th percentile for our CFO compared to ~~the chief executives of companies~~their counterparts in our executive compensation peer ~~group~~group; (ii) above the 75th percentile for Mr. Smith compared to Senior Vice Presidents and ~~generally~~General Counsels in our executive compensation peer group; and (iii) between the 50th and ~~75th~~60th percentiles for our other NEOs compared to similar executives of companies in our executive compensation peer group.

In ~~2022,~~2023, 90% of any award earned under the annual cash incentive plan was based on Pretax Income Margin and 10% of any award earned was based on Tons Sold Growth.

The Pretax Income Margin portion of the 2023 annual cash incentive plan opportunity was established by the Compensation Committee on a sliding scale, ranging from zero for results below the 3.50% Pretax Income Margin threshold, of base salary for results at the 3.50% Pretax Income Margin threshold, a target of 135% of base salary for

If the Company achieved a ~~2022~~ Pretax Income Margin within the range of 3.50% and 9.00%, then mathematical interpolation would be applied to determine the actual incentive award in the applicable range (threshold to target or target to maximum). 2022 Pretax Income Margin was 14.3%, which resulted in each NEO receiving the maximum Pretax Income Margin award under the 2022 annual cash incentive plan equal to 270% of base salary. For purposes of the annual cash incentive plan, Pretax Income Margin is calculated based on the Company’s annual income before income taxes as a percentage of net sales as adjusted for certain non-recurring items.

In addition to Pretax Income Margin, ~~in 2022~~ the Compensation Committee ~~determined that~~set a portion of the 2023 target annual cash incentive award to be earned based upon Tons Sold Growth at 15.0% of ~~15%~~base salary, which amount would be earned if Tons Sold Growth exceeded the MSCI Benchmark by 1.0%.

Target annual cash incentive opportunities approximate: (i) the 75th percentile for our CEO and President; (ii) the 50th percentile for our former CEO; and (iii) between the median and 75th percentile for our other NEOs, in each case, compared to similar executives of companies in our executive compensation peer group.

When analyzing the actual and potential payouts under the Company’s annual cash incentive plan, especially its maximum incentive awards and resulting cash compensation levels, the Committee found the plan supported its pay-for-performance principles in ~~2022.~~2023.

Long-Term Equity Incentive Compensation

The Compensation Committee recommends grants of annual discretionary equity awards for the NEOs, but the independent directors of the full Board approve all such grants. The Compensation Committee considers executive compensation peer group data from the independent compensation consultant as well as the recommendations of our CEO with respect to any grants of equity awards to the NEOs (other than the CEO) and other executive officers, as well as to corporate officers and other key employees.

In making its recommendations to the independent directors, the Compensation Committee considers the position of the NEO, his or her importance to the Company’s results and operations, his or her individual performance and contributions, the equity awards previously granted to that individual, the terms and market value of the equity grant, the total value of the equity grant and the relative number of such recommended grants among the various individuals then under consideration for grants, as well as the potential dilution and the related expense as a percentage of pretax income. The Committee also considers market data for executives in comparable positions within our executive compensation peer group.

From 2017 through 2021, 80% of our CEO and President’s target equity awards and 60% of our other NEOs’ target equity awards were performance-based, while 20% of our CEO and President’s target equity awards and 40% of our other NEOs’ target equity awards were service-based. In 2022 and 2023, 80% of all NEO target equity awards ~~issued were~~have been performance-based and 20% ~~were~~have been service-based. Accordingly, 80% of the NEOs’ RSU awards granted in 2022 and 2023 will vest if, after a three-year period from January 1, 2022 through December 31, 2024, and January 1, 2023 through December 31, 2025 the Company achieves an ROA result at or above a minimum threshold. The remaining 20% of the NEOs’ awards granted in 2022 and 2023 will vest on December 1, 2024 and 2025, respectively, subject to the individuals’ continued service through such date. The allocation of

performance-based and service-based awards is intended to balance performance and retention objectives. In striking an appropriate mix between service- and performance-based equity awards, the Compensation Committee sought to design a policy that incentivizes strong performance balanced with the retention value of our long-term equity awards since the Company does not maintain employment agreements with its executive officers. The RSUs will be forfeited if the ROA results are not achieved at or above the threshold (for performance-based awards), or the individual voluntarily leaves the Company or is terminated for cause. The award agreements for the RSUs provide for prorated vesting if an individual’s employment terminates (i) due to a qualifying retirement, death or disability or (ii) without cause following a change in control.

ROA for the performance period is calculated as the average of the three years of annual ROA (operating income for the year (as adjusted for certain non-recurring items) divided by the average total assets for the year) in the performance period. Mathematical interpolation is applied to determine the actual incentive award if the calculated ROA result is inwithin the applicable range (threshold to target or target to maximum).

The 2009 amendment and restatement shifted the risk of the performance of the individual’s retirement plan investments from the Company to the participants, eliminated the offsets to the SERP benefit and reduced the benefit amount to 38% of the average of the participant’s highest five years total cash compensation during the final ten years of employment ~~(from~~(down from 50% ~~less~~and including offsets for the value of ~~the~~ Company contributions to the Reliance Steel & Aluminum Co. Master 401(k) Plan (the ~~"401(k) Plan"~~“401(k) Plan”) and the Reliance Steel & Aluminum Co. Employee Stock Ownership Plan ~~("ESOP"~~(“ESOP”) as well as social security benefits). The 2009 amendment and restatement also brought the SERP into compliance with Rule 409A under the Internal Revenue Code, among other things. Because of her long tenure with the Company, Mrs. Lewis is the only remaining active ~~remaining~~ participant in the SERP.

~~COMPENSATION DISCUSSION AND ANALYSIS~~

Deferred Compensation Plan. ~~We also~~ The Company adopted the Deferred Compensation Plan to provide supplemental retirement benefits to certain key employees as well as to combine and replace certain deferred compensation plans and supplemental executive retirement plans that existed at certain companies when we acquired them. The Deferred Compensation Plan does not provide for any minimum or guaranteed rate of return.

The Deferred Compensation Plan was amended and restated effective January 1, 2013 to allow all corporate officers and subsidiary officers to participate. Messrs. Ajemyan, ~~Hoffman,~~Durham, Koch and Smith received discretionary Company contributions under the Deferred Compensation Plan in ~~2022.~~2023.

The Compensation Committee considers the SERP benefits and any benefits under the Deferred Compensation Plan in its analysis of each of the NEOs’ total compensation. In comparing the ~~values of the SERP and~~discretionary Company contribution benefit under the Deferred Compensation Plan ~~against~~to the retirement benefits offered to similar executives at companies in ~~the Company’s~~our executive compensation peer group, ~~in July 2022,~~ the Compensation Committee found that ~~on balance~~ the target values ~~of these benefits approximated competitive norms~~ for Messrs. Ajemyan, Koch, Durham and Smith would be between the ~~NEOs as a whole.~~25th and 50th percentiles.

In addition, as a former employee of Earle M. Jorgensen Company, a wholly-owned subsidiary of Reliance, Mr. ~~Hoffman~~Durham is entitled to receive the cash equivalent of ~~3,962~~approximately 725 shares of Reliance common stock with a market value of ~~$802,067~~$202,868 as of December 31, ~~2022~~2023 under the Earle M. Jorgensen Company Supplemental Bonus Plan (the ~~"EMJ~~“EMJ Bonus ~~Plan"~~Plan”).

Other Benefits

Limited Perquisites. Perquisites provided by the Company are limited in both type and monetary value. The Company reimburses certain of our NEOs for certain memberships used primarily for business purposes. Mrs. Lewis and Messrs. Ajemyan and Smith each received $700 of taxable parking allowance in 2022. Messrs. Ajemyan and Smith each received $900 as reimbursement for home office internet service in 2022.

Other Benefits. Other than the SERP and the Deferred Compensation Plan (and, for Mr. ~~Hoffman,~~Durham, the EMJ Bonus Plan), described above, the NEOs participate in the Company’s health, welfare, retirement and other plans, such as the 401(k) Plan and the ESOP, on the same basis as these benefits are generally available to all eligible employees. The ESOP plan is closed to new enrollment and the Company is not currently making annual contributions to the plan.

ADDITIONAL INFORMATION

No Employment Agreements; Potential Payments Upon Termination or Change in Control

We do not have individual employment agreements that provide change in control or severance benefits to any of our executive officers, including the NEOs. We have been successful in attracting and retaining an experienced and effective management team without the use of such agreements. Most of our executives have been with Reliance for many years and have built their careers at Reliance and/or its subsidiaries. On average, our NEOs have more than 1615 years’ tenure with Reliance and over 27 years of industry experience. Generally, if an employee ceases to be employed at the Company before his or her RSUs vest, these units will expire on the date the employee is terminated. However, the executive (or their beneficiary) is eligible to receive a prorated payout of his or her RSUs based on the number of days employed during the vesting period if the termination of employment is without cause following a change in control or results from death, disability, or qualifying retirement.

COMPENSATION DISCUSSION AND ANALYSIS

(1)

Includes the prorated value of the number of unvested RSUs granted in ~~2021~~2022 and ~~2022~~2023 based on Company ROA calculated over a shortened ~~performance~~measurement period ended on December 31, 2022 (based on performance through such date). The value of long-term equity incentive compensation included in this amount is based on a price per share of $202.44, the closing price of the Company’s common stock on December 31, 2022.2023.

(2)

Excludes certain benefits generally available to salaried employees, such as certain disability benefits, accrued vacation and distributions under our 401(k) and ESOP plans.

(3)

Represents the amount of benefit in excess of the present value of accumulated benefits payable on retirement by the SERP or the amount of unvested company contributions under the Deferred Compensation Plan (see page ~~58)~~45).

The annual cash incentive and 2021 performance-based RSU awards do not provide incremental value upon termination or a change in control without termination occurring on December 31, ~~2022,~~2023, as the NEO would be fully vested in the ~~2022~~2023 annual cash incentive and the performance-based restricted stock awards granted in ~~2020,~~2021, having been employed throughout the entire performance period.

The SERP provides that if a participant is terminated without cause following a change in control or aafter the participant has attained age 55 and completed 10 years of service, then any unvested rights of a participant to receive certain retirement benefits under the SERP shall become fully vested.

The Deferred Compensation Plan provides that a participant becomes vested in any Company contributions upon the earlier of: (i) the date such participant attains age 55 and has at least five years

of service in an eligible role; and (ii) the date such participant attains age 62. The Deferred Compensation Plan provides that the participants receive their vested account balance upon termination orand receive their total account balance upon a change in control.

The ~~RSUs~~RSU award agreements provide ~~that upon~~for the following prorated vesting if an individual’s employment terminates (i) due to a qualifying retirement, death or disability or (ii) without cause following a change in control ~~if a recipient’s employment is terminated or substantially diminished~~ (a.k.a., double trigger):

•

the service-based RSUs will become vested by prorating the number of such RSUs as if the vesting period ended on the date of the termination, and

•

the performance-based RSUs will become vested only upon the achievement of the relevant performance metric measured during a shortened performance period ending on the most recent quarter-end before the date of the termination, with the number of shares prorated based on such shortened performance period.

Stock Ownership Requirements

Our stock ownership policy requires our officers to own shares of our common stock (including unvested service-based RSUs) equal in value to a multiple of their respective ~~annual~~ base salaries within five years from the date of each officer’s appointment. Includes shares held indirectly under the ESOP and the 401(k) Plan.

The stock ownership guidelines are intended to discourage excessive ~~risk taking~~risk-taking and to reinforce the alignment of interests between our officers and stockholders.

Clawback and Recoupment Policy

To further reduce the possibility of excessive ~~risk taking,~~risk-taking, and to foster a culture that emphasizes integrity and accountability, the Compensation Committee has adopted a ~~clawback~~compensation recovery policy pursuant to which the Company must recover erroneously awarded performance-based compensation (generally consisting of the annual cash incentive and ~~recoupment policy~~performance-based RSUs) from senior officers in the event the Company is required to prepare an accounting restatement due to material noncompliance of the Company with any financial reporting requirement under the securities laws (including any required accounting restatement to correct an error in previously issued financial

Hedging and Pledging Policies

Our Insider Trading and Securities Compliance Policy contains provisions restricting the hedging and pledging of Company securities by our directors, officers and certain employees.

Hedging Policy. Directors, officers and designated insider employees subject to our Insider Trading and Securities Compliance Policy are prohibited from purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or otherwise engaging in transactions that hedge or offset any change in the value of the Company’s securities held directly or indirectly by such individual, including units granted as a component of compensation or otherwise. None of the Company’s directors or executive officers had any such hedging arrangements in place as of December 31, ~~2022.~~2023.

Pledging Policy. Directors, officers and designated insider employees subject to our Insider Trading and Securities Compliance Policy are prohibited from holding securities of the Company in a margin account or pledging such securities as collateral for loans, except for securities pledged as of the effective date of the policy or which have already been pledged at the time an individual becomes a director, officer or designated insider employee. None of the Company’s directors or executive officers had any such pledging arrangements in place as of December 31, ~~2022.~~2023.

Tax and Accounting Considerations

Under Section 162(m) of the Internal Revenue Code, a publicly held company generally is limited to a $1 million annual tax deduction for compensation paid to each of its ~~"covered employees,"~~“covered employees”, which ~~are~~include the NEOs ~~(as~~as well as certain other officers who were covered ~~employees).~~employees. Prior to the enactment of the Tax Cuts and Jobs Act of 2017 (the ~~"TCJA"~~“TCJA”), certain ~~"qualified~~“qualified performance-based ~~compensation"~~compensation” was excluded from the $1 million deduction limit. The TCJA eliminated most of the exceptions from the $1 million deduction limit, except for certain grandfathered arrangements in place as of November 2, 2017, when the plan is not modified or where amounts payable under the plan are not subject to discretion. As a result, most of the compensation payable to our NEOs (and other covered employees) in excess of $1 million per person in a year will not be fully deductible.

While the Compensation Committee believes that the tax deductibility of compensation is a factor to be considered, the Compensation Committee believes that it is in the best interests of the Company and our stockholders for the Committee to exercise discretion to grant awards even if the award is not deductible for tax purposes. Despite the limits placed on the deductibility of all the stock-based compensation earnings of our corporate officers, the tax benefit realized from our stock-based compensation plans in ~~2022 increased to $8.0 million from $6.8 million in 2021.~~

~~The~~In February 2024, the Compensation Committee, in consultation with Pay Governance, and with input from management, determined that it would be in the best interests of the Company’s stockholders to ~~include a market benchmark in calculating~~update the metrics used for measuring the Company’s financial performance under the 2024 annual cash incentive ~~award under the tons sold metric.~~plan as well as performance-based RSU awards granted in 2024.

As in 2022, the Compensation Committee set the portion of the target annual cash incentive award to be earned based upon tons sold at 15.0% of base salary and the maximum award at 30.0% of base salary.

In 2023, the Company’s performance under the ton sold metric will be measured against the total tons of metal sold by the U.S. metals service center industry as published by the MSCI (the "MSCI Benchmark"). For 2023, the Compensation Committee set the portion of the target annual cash incentive award to be earned based upon tons sold at 15.0% of base salary, which amount would be earned if tons sold exceeded the MSCI Benchmark by 1.0%. The maximum award of 30.0% of base salary would be earned if tons sold exceeded the MSCI Benchmark by 2.0%. No payment under the tons sold metric would made if the Company’s tons sold underperformed the MSCI Benchmark. Mathematical interpolation is applied to determine the actual incentive award for tons sold that is in excess of MSCI Benchmark by less than 2.0% (threshold to target or target to maximum).

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation Committee made the 2024 annual cash incentive plan more demanding by increasing the pretax income margin targets. As in 2023, the total annual cash incentive opportunity in 2024 for each NEO under the pretax income margin metric is 135% of their base salary if the targets are achieved. The 2023 pretax income margin metrics and the increased 2024 metrics are set forth in the table below:

	2023 Pretax Income Margin Metrics		2023 Performance Award (% of Base Salary		2024 Pretax Income Margin Metrics		2024 Performance Award (% of Base Salary
Threshold		3.50%		20.0%		5.00%		20.0%

Maximum		9.00%		270.0%		10.00%		270.0%

The Compensation Committee also made the performance-based RSU awards granted in 2024 more demanding by increasing the three year ROA performance metrics. As in prior years, the performance-based awards granted in 2024 will vest if the Company achieves an ROA result over the three-year performance period ending December 31, 2026 at or above a minimum threshold. The 2023 three year ROA performance metrics and the increased 2024 three-year ROA performance metrics are set forth in the following table:

	2023 ROA Metrics		2023 Number of RSUs Vested		2024 ROA Metrics		2024 Number of RSUs Vested
Threshold		6.00%		25.0%		7.00%		25.0%

Maximum		13.00%		200.0%		13.00%		200.0%

As in prior years, 80% of the target performance-based RSU awards granted to the CEO, CFO and COO in 2024 are performance-based and 20% are service-based. To achieve a more appropriate balance of performance and retention objectives, 70% of the target performance-based RSU awards granted to the other corporate officers, including the other two NEOs, in 2024 are performance-based and 30% are service-based.

PAY RATIO DISCLOSURE

Presented below is the ratio of annual total compensation of our CEO to the annual total compensation of our median employee (excluding our CEO). The ratio presented below is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Securities Act of 1933, as amended. The pay ratio rules provide companies with flexibility to select the methodology and assumptions used to identify the median employee, calculate the median employee’s compensation and estimate the pay ratio. As a result, our methodology may differ from those used by other companies, which likely will make it very difficult to compare pay ratios with other companies, including those within our industry.

We identified the median employee from the Company’s employee population as of December 31, ~~2022.~~2023. After excluding employees under the ~~"de~~“de minimis ~~exemption" (as~~exemption” (as described below), the Company’s employee population consisted of ~~13,871~~14,337 employees located in the U.S., Canada, Mexico ~~South Korea~~ and the United Kingdom. For purposes of identifying the median employee, the Company was permitted to exclude up to 5% of its total employees who are non-U.S. employees. The Company relied on this exemption to exclude the employee populations of the following jurisdictions, which collectively accounted for less than 5% of the Company’s total employee population of ~~14,548~~15,037 as of

In identifying our median employee, we calculated the annual total compensation of each employee for the 12-month period that ended on December 31, ~~2022.~~2023. Annual total compensation for these purposes included base salary, overtime wages, bonus, commissions, incentives and comparable cash elements of compensation in non-U.S. jurisdictions and was calculated using internal payroll records. Specifically excluded from the annual compensation measure in identifying the median employee were retirement benefits and stock-based compensation. The compensation for full-time employees who were not employed by us for the entire 12-month period was annualized to reflect compensation for the entire 12-month period.

The ~~2022~~2023 annual total compensation for our CEO as determined under Item 402(u) of Regulation S-K was ~~$14,944,260.~~$14,319,273. As reflected in the Summary Compensation Table, ~~$7,200,364~~$7,200,503 of our CEO’s total ~~2022~~2023 compensation was equity-based of which 80% is tied to performance targets. The ~~2022~~2023 annual total compensation for our median employee was ~~$69,488.~~$72,742. The ratio of our CEO’s annual total compensation to our median employee’s total cash compensation for fiscal year ~~2022~~2023 is approximately ~~215~~197 to 1.

TABLE OF CONTENTS

EXECUTIVE COMPENSATION TABLES

The SEC’s rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

(a)

Fair value of equity awards is calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, ~~Compensation—~~Compensation — Stock Compensation. The fair value of unvested service-based RSUs, as well as the fair value of all RSUs upon vesting, is based upon the closing sales price for a share of Reliance common stock on the NYSE for the applicable date of measurement. The fair value of unvested performance-based RSUs is based upon the probable outcome of the applicable performance conditions at the time of measurement.

(b)

Service cost is calculated as the actuarial present value of benefits attributed to services rendered by the executive during the applicable fiscal year under the SERP, using the same methodology used in the Company’s GAAP financial statements included in its Annual Reports on Form 10-K.

(4)

Reflects the cumulative total stockholder return of the Company and an industry peer group consisting of publicly-traded metals service center companies (the ~~"industry~~“industry peer ~~group"~~group”), which is the same industry peer group included in the stock performance graph furnished with our Annual Reports on Form 10-K, for the year ended December 31, 2020, the two-years ended December 31, 2021, ~~and~~ the three years ended December 31, 2022 and the four years ended December 31, 2023, assuming a $100 investment at the closing price on December 31, 2019 and the reinvestment of all dividends. The cumulative total stockholder return reflects market prices at the end of each year and the reinvestment of dividends. Since there is no nationally-recognized industry index consisting of metals service center companies to be used as a peer group index, Reliance constructed the industry peer group. The industry peer group consists of Olympic Steel Inc., which has securities listed for trading on NASDAQ; Ryerson Holding Corporation and Worthington ~~Industries,~~Enterprises, Inc., each of which has securities listed for trading on the NYSE; and Russel Metals Inc., which has securities listed for trading on the Toronto Stock Exchange. The returns of each member of the industry peer group are weighted according to that member’s stock market capitalization.

In December 2023, Worthington Industries, Inc., which was included in the industry peer group at December 31, 2022, split into Worthington Enterprises, Inc. and Worthington Steel, Inc. The newly traded Worthington Steel, Inc. common stock received by the holders of Worthington Enterprises, Inc. common stock at the distribution date is not included in the cumulative total return of the industry peer group.

RELATIONSHIP BETWEEN COMPENSATION ACTUALLY PAID AND PERFORMANCE

The graphs presented below present the relationship during ~~2020-2022~~2020-2023 of CAP for our CEO and the average CAP of our non-CEO NEOs to: (1) our cumulative TSR and the cumulative TSR of the constituent companies in our industry peer group; (2) ~~our~~ net income; and (3) the Company’s annual ROA.

A significant portion of our executive compensation program is comprised of performance-based equity awards (see page ~~45)~~44), which were expected to be settled between ~~163.0%~~100.0% and 200.0% of target for the outstanding performance-based RSUs during each of the years ~~2022, 2021 and 2020.~~of 2020-2023. We believe our sequential record financial performance in each of the years 2022 and 2021 and significant increases in our TSR during those years when compared to 2020 drove increases in compensation actually paid to our ~~NEOs, which~~NEOs. For 2023, our TSR was ~~aligned with~~greater than in each of the ~~value provided~~years 2022 and 2021, however compensation actually paid to our ~~stockholders from~~non-NEOs declined as a result of the ~~increase~~promotion of our President (non-CEO in ~~our stock price resulting from our performance.~~2020-2022) to CEO in 2023.

CAP, as required under SEC rules, reflects changes in fair value to unvested and vested equity awards that generally fluctuates from year to year due to the number of RSUs vested during the year, year-end stock prices and changes in the estimated number of common shares that are expected to settle performance-based RSU units based on the probable achievement of performance goals. Unvested awards remain subject to significant risk from forfeiture conditions and future declines in value based on changes in our stock price. The presented CAP amounts are presented under calculations required

Reliance’s profitability measures during the periods presented were significantly impacted by changes in metals pricing. Year-over-year changes in average selling price per ton sold: decreased 9.6% in 2020; increased 54.3% in 2021; increased 18.5% in 2022; and decreased 16.4% in 2023.

The ~~higher~~lower CEO and non-CEO CAP in ~~each of the years 2022 and 2021~~2023 as compared to ~~2020~~2022 was ~~driven by our sequential years~~consistent with Mrs. Lewis’ promotion into the CEO role during 2023 and a portion of ~~record operational performance coming out~~her CAP comprised of ~~the COVID-19 pandemic that increased actual and expected payouts for vested or unvested performance RSUs to maximum levels under our~~ long-term equity incentive ~~compensation plan~~awards granted while in the President (non-CEO) role in 2022 and the resulting 35.5% and 24.8% sequential annual increases in our common stock price compared to a relatively unchanged stock price in 2020 ($119.76 at December 31, 2019 and $119.75 at December 31, 2020).2021.

DIRECTOR COMPENSATION

The Company’s philosophy is to provide competitive compensation necessary to attract and retain high-quality non-employee directors. We compensate each non-employee director with an annual retainer as well as an annual grant of stock awards. We do not pay additional fees for attendance at Board meetings, committee meetings, and meetings of the non-management or independent directors. We pay additional amounts to the chairs of the standing committees of the Board and the non-executive ~~Chairman~~Chair of the Board. Directors who are employees of the Company (currently, ~~Mr. Hoffman and~~ Mrs. Lewis) receive no additional compensation for service as a director. All directors are reimbursed for expenses incurred in connection with Board meetings, committee meetings, and meetings of the non-management or independent directors.

In ~~2022,~~2023, each non-employee director was paid an annual cash retainer of ~~$130,000~~$140,000 and received an award of ~~767~~615 shares of stock awards (approximately ~~$140,000~~$150,000 grant date fair value) which are not subject to vesting criteria. In addition, the Company paid the Audit Committee Chair an annual retainer of $25,000; the Compensation Committee Chair an annual retainer of $20,000; and the Nominating and Governance Committee Chair an annual retainer of $20,000. The Company’s non-executive ~~Chairman~~Chair of the Board also received an annual retainer of $150,000. All cash payments to directors in ~~2022~~2023 were paid in equal quarterly installments.

The Nominating and Governance Committee reviews the competitiveness of director compensation every other year, including the appropriateness of the form, mix and amount of director compensation, and makes recommendations to the Board concerning such compensation with a view toward attracting and retaining qualified directors. The Nominating and Governance Committee also seeks advice from the Company’s independent compensation consultant.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

PRINCIPLES OF CORPORATE GOVERNANCE

The Board of Directors has adopted Principles of Corporate Governance outlining the responsibilities of the Board. These Principles of Corporate Governance are posted on the Company’s website at https://~~investor.rsac.com/~~investor.reliance.com/corporate-governance-documents and are available in print to any stockholder who requests a copy from our Corporate Secretary at the address shown on the first page of this proxy statement. The Board’s primary role is to represent the interests of the Company’s stockholders in strategic and material decisions of the Company. Among the most important responsibilities are the determination of corporate policies, the identification and nomination of qualified independent directors, the selection and evaluation of the Chief Executive Officer, the ongoing review of the senior management team, planning for management succession and the determination of executive compensation. The Board also provides advice and guidance to management on a broad range of strategic decisions, including the review and approval of each significant acquisition and the annual capital expenditure budget, and annually reviews and approves management’s succession plan. In addition, the Board reviews management’s safety program and record.

SIZE AND COMPOSITION OF BOARD

The Board of Directors presently consists of ~~ten~~nine directors, ~~eight~~seven of whom are independent. All directors are elected to serve a one-year term. Since Mr. ~~Figueroa~~Hoffman is retiring from the Board and will not stand for re-election at the Annual Meeting of Stockholders in May ~~2023,~~2024, the Board expects to reduce the size of the Board to ~~nine members,~~eight directors, of whom seven will be independent. The Board has adopted a policy that directors should not stand for re-election after reaching age 75.

ATTENDANCE AT MEETINGS

Board members are expected to attend each Board meeting and each meeting of any committee on which such Board member serves, and are encouraged to attend the Company’s Annual ~~Meeting (including participating in the meeting virtually, in the case of this year’s meeting).~~Meeting. In addition, annually, the Board will tour one or more of the Company’s facilities and meet with local management of those facilities, as well as hold a strategic planning session. During ~~2022,~~2023, the Board of Directors met ten times, including meetings held by conference telephone call. All current directors attended at least 90% of the Board and committee meetings in ~~2022.~~2023. All nine directors then serving on the Board attended the virtual Annual Meeting held in May ~~2022.~~2023.

COMMUNICATING WITH THE BOARD

PROXY ACCESS

The Company’s proxy access bylaw provision permits a stockholder, or a group of up to 20 stockholders, owning at least three percent (3%) of the Company’s outstanding common stock continuously for at least three years, to nominate and include in the Company’s proxy statement director nominees for up to the greater of two directors or 25% of the number of directors then serving on the Board, subject to the terms and conditions specified in the Company’s Bylaws. We did not receive any director nominations under our proxy access bylaw for the Annual Meeting.

CODE OF CONDUCT

Reliance has ~~adopted~~ a Code of Conduct, which includes a code of ethics, that applies to all directors, executive officers and senior management, including the President and Chief Executive Officer. Code of Conduct training is assigned to all new

employees upon hire and to existing employees regularly. The Code of Conduct training includes a certification to confirm that employees are familiar with and agree to abide by the Code of Conduct and that they have reported, pursuant to the provisions of the Code of Conduct, any suspected or potential violations of law or Company policy.

Employees are required to report any conduct that they believe to be an actual or apparent violation of the Company’s policies on business conduct. Retaliation against any employee who seeks advice, raises a concern, reports misconduct, or provides information in an investigation is strictly prohibited. Our Audit Committee has procedures to receive, retain and treat complaints received regarding accounting, internal accounting controls, or auditing matters and to address confidential and anonymous submissions by employees with concerns regarding questionable accounting or auditing matters.

In addition, the following documents are available on our website at https://~~investor.rsac.com/~~investor.reliance.com/corporate-governance-documents and in print to any stockholder who requests them:

•

Code of Conduct;

•

Anti-Bribery and Anti-Corruption Policy;

•

U.S. Political Activity and Spending Practices Policy; and

•

Human Rights Policy.

To facilitate the reporting of questionable accounting, internal accounting controls, or auditing matters, the Company has established an anonymous reporting hotline and website through which employees can submit complaints on a confidential and anonymous basis. The hotline and website are provided by an independent third-party and are available worldwide. These reports are confidential and anonymous. Procedures are in place to investigate all reports received by the hotline relating to questionable accounting, internal accounting controls, or auditing matters and to take corrective action, if necessary. The Audit Committee is notified of these reports at every quarterly committee meeting, or sooner, if necessary.

In the event Reliance amends or waives any of the provisions of the Code of Conduct applicable to our principal executive officer, principal financial officer, principal accounting officer or controller that relates to any element of the definition of ~~"code~~“code of ~~ethics"~~ethics” enumerated in Item 406(b) of Regulation S-K under the Securities Act of 1933, as amended, Reliance intends to disclose these actions on its website.

changes in the compensation policy and to make all other determinations for administering the plans and policies; provided that such determinations relating to corporate officers are subject to the approval of the independent directors of the Board. The Compensation Committee annually reviews its Charter.

Each member of the Compensation Committee is an independent director as defined in the listing standards for the NYSE, including the additional independence criteria applicable to compensation committee members. Ms. Colonias has served as Chair of the Compensation Committee since 2022. In ~~2022,~~2023, the Compensation Committee met five times, and conferred by phone and email as needed.

Nominating and Governance Committee.

In ~~2022,~~2023, the Nominating and Governance Committee met ~~four~~three times and conferred by phone and email as needed.

NOMINATION OF DIRECTORS

Nominations for the Board of Directors are made by the Nominating and Governance Committee and considered by the Board of Directors acting as a whole. The Nominating and Governance Committee has not adopted a specific policy regarding the consideration of director candidates recommended by stockholders, but seeks candidates by any method the Committee determines to be appropriate, including consideration of director candidates proposed by stockholders. Stockholders may propose director candidates for consideration by the Nominating and Governance Committee by sending a letter addressed to the Chair of the Nominating and Governance Committee in care of the Corporate Secretary of Reliance at the Company’s corporate headquarters address appearing at the top of the first page of this proxy statement. Candidates recommended by stockholders are evaluated ~~in the same manner~~ by the Nominating and Governance Committee in the same manner as candidates recommended by other parties. To comply with the universal proxy rules, stockholders

who intend to solicit proxies in support of director nominees other than the Company’s director nominees must also provide the Company with the notice and other information required by the universal proxy rules as set forth in our Bylaws.

THE ROLE OF THE BOARD OF DIRECTORS IN RISK ASSESSMENT

The Board of Directors as a whole has the responsibility to oversee risk assessment and regularly receives reports from members of senior management and Chairs of the ~~Committees~~committees as to any material risk to the Company, including operational, financial, legal, or regulatory risks, succession issues or risks that could adversely impact the Company’s reputation. The Audit Committee has taken the lead role in connection with the oversight of risks associated with or disclosable in the Company’s financial statements and certain regulatory risks. The Audit Committee meets with the Company’s independent registered public accounting firm in executive session (i.e., without management) on a quarterly basis

82~~2023 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

~~BOARD OF DIRECTORS AND CORPORATE GOVERNANCE~~

and receives quarterly updates directly from the Company’s Vice President, Enterprise Risk and Director, Internal Audit. The Audit Committee conducts an annual discussion regarding potential risks to the Company from a financial reporting and regulatory standpoint, with input from the Company’s financial management, the Vice President, Enterprise Risk, the internal audit team, in-house counsel and the Company’s independent registered public accounting firm.

In addition, the Audit Committee regularly reviews the Company’s assessment of cybersecurity threats and risk, data security programs and information technology risks and potential ~~breach~~cybersecurity incidents with management, including the Company’s Chief Information Officer and Senior Director, Information Security.

To the extent that a risk arises within the purview of our Nominating and Governance Committee or the Compensation Committee, management reports to the applicable ~~Committee.~~committee. The Chair of the appropriate ~~Committee~~committee then reports to the Board as a whole ~~as to~~ any material risks and the evaluation or mitigation of those risks after any appropriate investigation and discussions with management and any outside counsel or consultant who may be invited to discuss the issue.

In the Board’s executive sessions, the non-executive ~~Chairman~~Chair of the Board regularly holds a general discussion of potential and actual risks. The ~~Chairman~~Chair of the Board conducts the meetings, administers the activities of the Board, and facilitates communication between management and the Board. In addition, the ~~Chairman~~Chair of the Board makes the final determination of the Board’s ~~agenda.~~meeting agendas. The Company’s President and Chief Executive Officer, Chief Operating Officer, Chief Financial Officer, and General Counsel all regularly attend the meetings of the Board of Directors and its Committees and are available to discuss any material risk with the Board or any Committee. In addition, these officers regularly report to the Board of Directors on any material or significant risks of which they become aware. To the extent that the Board desires it, or the risk warrants it, other Company personnel may be asked to prepare and present a report to the Board and outside counsel or an appropriate consultant may be invited to discuss the issue at a Board meeting. The Company believes that these procedures enable the Board to promptly and adequately assess risks that may have a material impact on the Company and to oversee any mitigation to the extent the Board deems ~~it to be~~ appropriate.

RISKS RELATED TO COMPENSATION PLANS

Our Compensation Committee has concluded that the Company’s various compensation plans do not encourage excessive or inappropriate risk taking or create any risk that is reasonably likely to have a material adverse effect on the Company. Each year our Compensation Committee reviews the Company’s existing compensation plans and policies for the NEOs and corporate officers to ensure that they continue to support the Company’s objectives and enhance stockholder value, including to the extent there have been any changes to the Company’s risk profile.

Throughout our Company, compensation of our management and key employees is structured with the same elements as for our NEOs:

•

base salary,

•

performance-based cash incentive awards,

•

equity compensation, and

•

a 401(k) plan.

Sales personnel are generally ~~are also~~ paid a base salary plus commissions on the gross profit from sales from their particular geographic territory or ~~location as well as a base salary.~~location. Our cash incentive plans for local management teams provide variable compensation and are performance-based programs tied to various financial and operational measures, including, most commonly, pretax income, return on manageable assets, gross profit, inventory turn, credit performance and other similar

From time to time, discretionary bonuses may be awarded to individual employees based upon that individual’s performance and contribution to the results of the business unit, subsidiary or the Company as a whole.

The NEOs are entitled to performance-based incentive cash awards only if the Company’s performance meets certain thresholds. Performance-based RSU awards granted to NEOs and other key employees are subject to forfeiture if performance criteria are not met at the end of the three-year performance measurement period. The Compensation Committee annually considers how our compensation policies and practices may affect our risk profile and whether such policies and practices may encourage undue risk-taking by our employees. More specifically, the Compensation Committee considers the general design philosophy of our policies and practices for our employees whose conduct would be most affected by incentives established pursuant to these compensation policies. The Compensation Committee believes that having multiple performance awards over multiple periods will reduce the likelihood of excessive ~~risk taking.~~risk-taking. See ~~"Compensation~~“Compensation Discussion and ~~Analysis"~~Analysis” above for a discussion of our executive compensation program, including our performance-based awards. Moreover, ~~the Compensation Committee,~~ to further reduce the possibility of excessive ~~risk taking, adopted~~risk-taking, the Compensation Committee has a ~~clawback and recoupment~~compensation recovery policy ~~that requires all or a portion~~pursuant to which the Company must recover erroneously awarded performance-based compensation (generally consisting of the ~~NEOs’~~annual cash incentive ~~cash awards or RSU awards~~and performance-based RSUs) from senior officers in the event the Company is required to ~~be returned~~prepare an accounting restatement due to material noncompliance of the Company with any financial reporting requirement under the securities laws (including any required accounting restatement to correct an error in previously issued financial statements that is material to the ~~Company~~previously issued financial statements, or that would result in a material misstatement if the ~~financial statements are restated or there is a material adverse change~~error were corrected in the ~~factors underlying~~current period or left uncorrected in the ~~performance criteria.~~current period). To encourage retention of key employees, service-based RSU awards will vest only if the individual continues to be employed by the Company or an affiliate until the end of the three-year measuring period.

The nature of our business limits potential risk of the actions of individual employees and individual transactions. Our primary business is to serve customers by providing quick delivery, metals processing and inventory management services, principally for small orders. Our metals service centers wrote and delivered over 4.6 million orders during ~~2022~~2023 or an average of ~~18,460~~18,280 per day, with an average price of approximately ~~$3,670~~$3,210 per order. Most of our ~~metals service center~~ customers are located within ~~a 200-mile radius~~200 miles of the Reliance metals service center serving them. We believe that our focus on small orders with quick turnaround differentiates us from many of the other large metals service center companies and allows us to provide better service to our customers, and that it also mitigates excessive ~~risk taking.~~risk-taking. It is uncommon for our operating units to enter into a material contract or agreement, and, on those occasions when a material contract is being considered, senior management is involved. Further, given the internal processes and controls that we have in place, it would be difficult for any individual or group of individuals to manipulate the results of their operating unit in a manner that would have a material effect on the Company’s consolidated results.

EXECUTIVE SESSIONS AND THE INDEPENDENT, NON-EXECUTIVE ~~CHAIRMAN~~CHAIR

Non-management directors meet regularly in executive sessions without management. ~~"Non-management"~~“Non-management” directors are all those who are not Company officers or employees and include directors, if any, who are not ~~"independent"~~“independent” by virtue of the existence of a material relationship with the Company, former employee status or family relationship or for any other reason. Executive sessions of the non-management directors are led by the non-executive ~~Chairman. An executive session is~~Chair of the Board. Executive sessions of the non-management directors are held ~~immediately prior to each~~ regularly ~~scheduled quarterly Board meeting~~ and ~~other~~ sessions may be called by the non-executive ~~Chairman~~Chair of the Board in his ~~own~~ discretion or at the request of the Board.

Mr. Kaminski was elected Lead Director by the independent directors in January 2015. In July 2016, Mr. Kaminski was elected the independent, non-executive ~~Chairman~~Chair of the Board by the independent directors. Consistent with our Principles of Corporate Governance, the Board currently does not have a lead independent director because the ~~Chairman~~Chair of the Board is an independent director. The Board believes that

~~TABLE OF CONTENTS~~

~~BOARD OF DIRECTORS AND CORPORATE GOVERNANCE~~

having an independent director serve as the non-executive ~~Chairman~~Chair of the Board is the appropriate leadership structure for our Company at this time because it allows our Chief Executive Officer to focus on executing our Company’s strategic plan and managing our operations and performance, while allowing the ~~Chairman~~Chair of the Board to focus on the effectiveness of the Board and provide independent oversight of our senior management team.

•

Director Karen W. Colonias served as ~~the President and Chief Executive Officer~~a director of SSD until ~~December 2022.~~April 26, 2023. Subsidiaries of the Company conducted approximately ~~$1,459,000~~$1,498,000 in transactions with SSD in ~~2022.~~2023.

Subsidiaries of the Company conducted approximately ~~$12,350,000~~$10,416,000 in transactions with Emerson in ~~2022.~~2023.

characteristics or attributes are sought in all Board members, including integrity, strong professional reputation, a record of achievement, constructive and collegial personal attributes, and the ability and willingness to devote sufficient time and energy to serve on our Board. The Nominating and Governance Committee and the Board of Directors believe that each of the Company’s current Board members meets these criteria and understands what factors result in the Company outperforming its industry peers. The Company desires to have directors who will commit a substantial amount of time to serving on the Board to ensure a greater understanding of the Company’s business and culture and to provide continuity and stability to the Board. Reliance recognizes the value of diversity. Although the Board does not have a formal diversity policy, it believes that diversity is an important factor in determining the composition of the Board and considers it in making nominee recommendations.

The Board is committed to prioritizing experience relevant to the Company’s strategy and business, ensuring that potential ~~board~~Board candidates with a diversity of race, age, ethnicity and gender are included in each pool of candidates from which Board of Directors nominees are chosen, and including potential candidates from varied backgrounds, including going beyond the traditional former CEO corporate background as a required criteria for new candidates. The Company will continue to evaluate board composition and opportunities to strengthen the Board of Directors.

ANNUAL BOARD AND COMMITTEE SELF-EVALUATIONS

conduct and culture of the Board and committees. The self-evaluations and summaries are shared and discussed with the full Board and each committee which allows the Board and each committee to share their perspectives and consider any necessary adjustments in response to the collective feedback from the self-evaluations. The Board also regularly assesses the individual directors’ qualifications, attributes, skills and experience to ensure appropriate representation on the Board.

DIRECTOR STOCK OWNERSHIP REQUIREMENTS

Directors are required to own shares of the Company’s common stock having a market value at least equal to $520,000; provided, that directors shall have a period of five years to acquire and begin maintaining that amount of the Company’s common stock. All of the directors are in compliance with their stock ownership requirements or are in the process of becoming compliant within five years of the date of appointment.

STOCKHOLDER ENGAGEMENT

To maintain our strong corporate governance practices and ensure that we regularly receive stockholder feedback, we must engage with investors. Throughout the year, we seek opportunities to connect with our investors to gain and share valuable insights into current and emerging global governance trends and the Company’s corporate governance policies and practices.

Management conducts extensive engagements with key stockholders. Officers participating in these engagements include our President and Chief Executive Officer, our Chief Operating Officer, and our Chief Financial Officer. In ~~2022,~~2023, we had direct discussions with stockholders holding ~~in excess of 23%~~approximately 28% of our outstanding shares of common stock in the aggregate. We pursue multiple avenues for engagement in addition to direct discussions with stockholders, including video and teleconference meetings, participating at various conferences, road shows and facility tours. These engagements include discussions about governance, compensation, sustainability and safety, as well as financial and operational matters, to ensure that management and the Board understand and address the issues that are important to our stockholders. The Board oversees the discharge by management of stockholder communication and engagement and receives regular reports on stockholder comments and feedback. The Board encourages dialogue on issues of interest to stockholders.

AUDIT COMMITTEE REPORT

The Audit Committee assists the Board of Directors in fulfilling the Board’s oversight responsibilities over our financial reporting process and systems of internal controls, monitoring the independence, qualifications and performance of our independent registered public accounting firm and the performance of our internal auditors, and maintaining open communication between the Board and the independent registered public accounting firm, the internal auditors, and financial management and has taken a lead role in financial risk assessment. During ~~2022,~~2023, the Audit Committee, which is composed entirely of independent, non-employee directors, met nine times.

The Audit Committee operates under a written Charter adopted by the Board that outlines its responsibilities and the practices it follows. The Audit Committee reviews and assesses the adequacy of the Charter at least annually and, when appropriate, recommends changes to the Board.

In fulfilling its responsibilities under the Charter, the Audit Committee reviewed and discussed our audited financial statements for ~~2022~~2023 with management and the independent registered public accounting firm, including the critical audit matter arising from the current period audit of the Company’s financial statements set forth therein. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the Securities and Exchange Commission. The Audit Committee also reviewed the written disclosures and the letter from the independent registered public accounting firm required by professional standards regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and discussed with the independent registered public accounting firm its independence from management and Reliance. The Audit Committee has also considered the compatibility of non-audit services rendered by our independent registered public accounting firm with its independence. The Audit Committee approved all fees paid to the independent registered public accounting firm for audit and non-audit services.

In reliance on the reviews and discussions outlined above, the Audit Committee recommended to the Board of Directors (and the Board subsequently approved the recommendation) that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, ~~2022~~2023 for filing with the Securities and Exchange Commission. The Audit Committee also evaluated and selected KPMG LLP as the Company’s independent registered public accounting firm for ~~2023.~~2024. This selection was ratified by the Board of Directors.

RELATED PERSON TRANSACTIONS AND INDEMNIFICATION

~~We currently employ~~In 2023, we employed two ~~individuals—~~individuals – Grant Hoffman and Ryan ~~Mollins—~~Mollins – who are immediate family members of current or former executive officers during ~~2022~~2023 and/or directors and whose individual aggregate compensation and benefits paid by the Company in ~~2022~~2023 exceeded $120,000. Each of these employees is compensated in a manner consistent with our employment and compensation policies applicable to all employees.

President and Director Karla R. Lewis is a director of Goodyear. Subsidiaries of the Company conducted approximately $1,180,000 in transactions with Goodyear in 2022. Reliance believes that these were all ordinary commercial transactions made at arm’s-length.

The Board of Directors has reviewed and approved these transactions under the standards described below.

Except as set forth above, since January 1, ~~2022,~~2023, there have been no related person transactions with any director or executive officer of the Company or any other related person, as defined in Rule 404 under Regulation S-K promulgated under the Securities Act of 1933, as amended, and none is proposed. Our policies and procedures with respect to the review of any proposed transactions are evidenced in the Company’s Code of Conduct, which requires that all material facts be disclosed to the full Board of Directors (or in the case of non-director employees, to corporate officers) and then all disinterested persons will review and consider what, if any, actions need to be taken. The Company’s Principles of Corporate Governance require directors to report any matter that conflicts with the interests of the Company or gives the appearance of a conflict immediately to the Chairman of the Board and the Chair of the Nominating and Governance Committee for the matter to be evaluated with respect to the continued appropriateness of such director’s Board membership, and any personal interest a director has in a matter before the Board must be disclosed to the Board and such director must excuse himself or herself from participation in the discussion and shall not vote on the matter. Furthermore, pursuant to its Charter, the Audit Committee conducts an annual review of any related person transactions for potential conflicts of interest.

We indemnify our directors and our officers to the fullest extent permitted by law so that they will be free from undue concern about personal liability in connection with their service to Reliance. Our Bylaws require indemnification, and we have also entered into agreements with those individuals contractually obligating us to provide this indemnification to them.

ANNEX A

RELIANCE, INC.

AMENDMENT NO. 2 TO
SECOND AMENDED AND RESTATED
2015 INCENTIVE AWARD PLAN

This Amendment No. 2 (“Amendment”) to the Reliance, Inc. Second Amended and Restated 2015 Incentive Award (“Plan”) is adopted by the Board of Directors of Reliance, Inc., a Delaware corporation (the “Company”), to be effective as of May 15, 2024, subject to receiving the approval of the shareholders at the Company’s Annual Meeting of Shareholders scheduled for May 15, 2024.

1. Purpose. The purpose of this Amendment is to amend the Plan. All terms in this Amendment shall have the same meanings as set forth in the Plan unless otherwise specifically defined.

2. Authority to Amend. Under Sections 13.1 and 13.2 of the Plan, the Board has express authority to amend the Plan from time to time, subject to stockholder approval if the amendment would: (i) increase the limit on the maximum number of Shares which may be issued under the Plan or the Award Limit, (ii) reduce the price per share of any outstanding Option or Stock Appreciation Right granted under the Plan or take any action prohibited by the Plan provisions prohibiting repricing, or (iii) cancel any Option or Stock Appreciation Right in exchange for cash or another Award in violation of specific terms of the Plan. The rules of the New York Stock Exchange require shareholder approval of equity compensation plans such as the Plan and material revisions thereto, including a material extension of the term of the plan. This Amendment is intended to extend the term of the Plan and, accordingly, the Board of Directors shall obtain stockholder approval for this Amendment.

3. Amendment to Term of Plan. Section 13.1(c) of the Plan is hereby amended in its entirety as follows:

“(c) No awards may be granted or awarded during any period of suspension or after termination of the Plan, and notwithstanding anything herein to the contrary, in no event may any Award be granted after February 24, 2030 (such date, the “Expiration Date”).
