BOARD LEADERSHIP STRUCTURE AND ROLE IN RISK OVERSIGHT

Full Board
Our Board is responsible for company-wide risk oversight, with our senior management bearing primary responsibility for managing these risks. The Board has separated the positions of Executive Chairman and CEO because it believes that the separation of the positions best enables the Board to ensure that our businesses, risks, opportunities and affairs are managed effectively and in the best interests of our stockholders. The Board’s oversight functions are primarily coordinated through our Board committees. Each of the Audit Committee, the Compensation Committee, and the GovNom Committee receives regular updates from management and works with management to assess potential risk exposures and understand the controls in place to mitigate potential impacts of such risks. In turn, our Board committees report to the full Board regularly regarding their respective areas of risk oversight responsibilities.
Gaming and Regulatory Risk Management |  |  |  |  |  | CSR Risk Management
We take pride in being a responsible member of the gaming industry. Our Corporate Compliance Committee oversees our Company’s gaming and regulatory compliance programs, which include gaming operations, government regulations applicable to gaming, and financial crime prevention such as anti-money laundering compliance and procedures. To ensure proper visibility and transparency, the Corporate Compliance Committee is chaired by a member of our Board who provides reports of each meeting to the GovNom Committee. |  |  |  |  |  | Our Board and management understand that operating on a foundation of corporate responsibility, community and stewardship are key to ensuring the Company’s long-term success. Our GovNom Committee is responsible for overseeing the Company’s strategies related to sustainability, inclusion and stewardship (collectively, our “CSR Initiatives”), with clear communication to the other Board committees and the full Board on these topics. The Committee actively engages with management regarding execution of our Corporate Social Responsibility (“CSR”) Initiatives and proper public disclosure on these topics.
Cybersecurity Risk Management
Led by a dedicated Information Security team, we operate with the highest degree of integrity in designing, delivering and maintaining a comprehensive program that safeguards our systems, services and data from cybersecurity-related threats. We regularly assess the efficacy of our program through externally-led technical simulations and assessments, including executive tabletop exercises. The results of these efforts are shared with the Board. Supporting these efforts, team members are required to take regular information security training, ensuring our entire team is aware of the latest risks in cybersecurity and is prepared to do their part to keep our systems and information secure. Our Chief Information Security Officer (“CISO”) and Senior Vice President of Legal Operations and Compliance provide day-to-day oversight of our data privacy and cybersecurity programs. These positions work in coordination with one another as well as with other members of management, including our CEO, Chief Financial Officer (“CFO”), General Counsel, and Chief Technology Officer and report directly to the CFO and to the General Counsel, respectively. Our CISO provides the full Board regular updates on cybersecurity and data protection matters, our information and data security initiatives and practices and any developments in the threat environments that we face.

IDENTIFYING AND EVALUATING DIRECTOR NOMINEES

Our GovNom Committee uses a variety of methods to identify and evaluate director nominees. Candidates may come into consideration via our Board members, professional search firms, stockholders or other persons. These candidates will be evaluated by our GovNom Committee and may be considered at any point during the year.

The GovNom Committee considers many factors in the identification and evaluation of potential director nominees. The overriding principle guiding our director nomination process is a desire to ensure that our Board serves our stockholders’ interests. We believe that having a range of skills, experiences and perspectives represented on the Board maximizes stakeholder value. The GovNom Committee may consider the following elements, among others, when evaluating director nominees:

| ✓ | Personal and professional integrity;

| ✓ | Leadership and strategic planning experience;

| ✓ | Business or management experience;

COMPENSATION DISCUSSION

AND ANALYSIS

Our named executive officers (“NEOs”) for the fiscal year ended December 31, 2024 are:

| • |  | Keith Smith, President and Chief Executive Officer;

| • |  | Josh Hirsberg, Chief Financial Officer and Treasurer;

| • |  | Stephen Thompson, Chief Administrative Officer;

| • |  | Theodore Bogich, Chief Operating Officer; and

| • |  | Uri Clinton, General Counsel and Corporate Secretary.

OUR COMPENSATION PHILOSOPHY

We remain focused on generating sustainable value through maintaining a diversified business model, strong operating efficiencies, and meaningful property-level investments to drive revenue and EBITDAR growth—all while achieving operating margins at competitive levels.

We continue to do so by demonstrating operational excellence, focusing on our core customer, and maintaining a balanced portfolio. We achieved these goals by delivering solid revenue and EBITDAR performance, and we maintained a disciplined yet forward-looking approach to capital allocation as we continued our quarterly share repurchases and dividend program, while keeping our focus on maintaining a strong balance sheet and an eye toward strategic opportunities. We value our commitment to creating value for our stockholders, and we continue to focus on a balanced approach as we look toward future growth.

We seek to align the compensation packages of our NEOs with our long-term strategy with a focus on appropriately balancing achievement of short- and long-term goals and promoting both innovation and discipline. This philosophy is reflected in our executive pay design in the following ways:

| ✓ | Total executive compensation is targeted at the 50th percentile of our peer group

| ✓ | Short-term incentive compensation is performance-based

| ✓ | Long-term compensation is 100% equity-denominated

| ✓ | Executives are subject to stock ownership guidelines

| ✓ | No employment agreements

Consistent with this philosophy, Mr. Smith’s 2024 target compensation was allocated as follows:

RISK CONSIDERATIONS IN OUR COMPENSATION PROGRAMS

Risk-taking is an essential part of growing a business, and prudent risk management is necessary to deliver long-term, sustainable stockholder value. In 2024, we reviewed compensation policies that can raise or lower our compensation risk profile, whether individually or collectively. This review includes our compensation strategy, short- and long-term incentive plan designs, executive severance agreements, benefits and perquisites, governance practices, and other policies and practices.

We believe the process we followed in 2024 is complete and sufficient for determining whether the Company’s practices are reasonably likely to encourage excessive risk taking. The Compensation Committee believes that our executive compensation program supports the objectives described above without encouraging inappropriate or excessive risk-taking.

We also believe our NEO compensation packages are competitive with other leading companies in the gaming and hospitality industries. Our compensation consultant, Exequity, assists us in conducting peer group analyses with a view toward establishing NEO total compensation that is competitive with our peers. The peer group considered for purposes of setting 2024 pay consisted of the following: Bally’s Corporation; Caesars Entertainment Corp.; Churchill Downs, Inc.; Golden Entertainment; MGM Resorts International; Penn National Gaming, Inc.; Red Rock Resorts, Inc.; Travel + Leisure Co.; Wynn Resorts, Ltd.; Hilton Grand Vacations, Inc.; Hyatt Hotels Corp.; Marriott Vacations Worldwide Corporation; Light & Wonder, Inc.; Six Flags Entertainment Corp.; and Vail Resorts, Inc.

SHORT-TERM INCENTIVES

Our commitment to operational efficiencies, balanced capital allocation, and growth mindset has allowed us to successfully maintain sustainable expansion and positive financial results.

The Compensation Committee continued its philosophy of executing on a measured approach to 2024 compensation, approving a design for the short-term incentive program based on a twelve-month performance period that considered a mix of (i) Adjusted Earnings Before Interest, Taxes, Depreciation, Amortization and Rent (“Adjusted EBITDAR”) after corporate expense1 and (ii) achievement of CSR initiatives. Total individual achievement also included a discretionary portion based on an individual’s overall contributions to the Company throughout the year.

Metric |  | Weight |  | Threshold |  | Target** |  | Maximum
Adjusted EBITDAR after Corporate Expense1* |  |  |  | 75 | % |  |  | $ | 1,087,200 | ** |  |  | $ | 1,359,000 |  |  |  | $ | 1,630,800** |

Discretionary |  |  |  | 15 | % |  |  |  | — |  |  |  |  | — |  |  |  |  | — |

1 | Adjusted EBITDAR is a non-GAAP financial measure. For supplemental financial data and corresponding reconciliation of Adjusted EBITDAR to the most comparable GAAP measure, please see Note 14 to our financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. Amount also excludes a $24,600,000 settlement expense related to termination of a commercial transaction.

* | In thousands

** | Threshold performance (80% of target) would have resulted in a payout of 50% of an executive’s target, and maximum performance (120% of target) would have resulted in a payout of 200% of an executive’s target.

*** | Level of achievement of the CSR metric was based on performance relative to goals for diversity spend rate (12.5%), waste diversion rate (58%), and maintaining specified published CSR ratings.

Maximum payout under the short-term incentive plan is capped at 200% of target. Actual 2024 Adjusted EBITDAR after corporate expense equaled $1,366,000, which resulted in performance at 100.5% of target, and the Company’s performance with respect to CSR initiatives was 105% of target. The blended payout received by each of our NEOs varied according to achievement of the discretionary component of each participant’s overall achievement. These amounts were paid entirely in 2025.

LONG-TERM INCENTIVES

We believe long-term compensation should serve both as an incentive for achieving longer term Company performance goals and as a retention tool for our executives. We also believe that stock price appreciation and ownership in the Company are valuable incentives that align executive and stakeholder interests.

Our NEOs receive long-term incentive compensation in the form of time-based RSUs, Performance Shares and Career Shares. Grants for the 2024 target period were as follows:

Executive |  | Target Time-Based RSUs ($)(1) |  | Target Performance Shares ($) |  | Career Shares ($)(2)
Keith Smith |  |  |  | 3,229,276 |  |  |  |  | 3,229,276 |  |  |  |  | 232,497 |
Josh Hirsberg |  |  |  | 1,117,829 |  |  |  |  | 1,117,829 |  |  |  |  | 127,512 |
Stephen Thompson |  |  |  | 869,408 |  |  |  |  | 869,408 |  |  |  |  | 109,516 |
Theodore Bogich |  |  |  | 869,408 |  |  |  |  | 869,408 |  |  |  |  | 109,516 |
Uri Clinton |  |  |  | 695,565 |  |  |  |  | 695,565 |  |  |  |  | 89,986 |

(1) | Time-based RSU grants generally vest over a three-year period.

(2) | Our Career Shares Program provides for the grant of RSUs (“Career Shares” or “Career RSUs”) under our Stock Incentive Plan. Each Career Share entitles a holder to one share of common stock upon vesting. To receive payout, grantees must be at least 55 years of age and must have been continually employed by us for a minimum of ten years. Retirement after ten years of service will entitle a grantee to 50% of his Career Shares. The amount increases to 75% after 15 years and 100% following 20 years of employment. Each NEO received an annual grant of Career Shares equal to 15% of his base salary in 2024. As of December 31, 2024, Messrs. Smith, Thompson, and Bogich were 100% vested in each of their respective Career Shares, Mr. Hirsberg was 75% vested, and Mr. Clinton was entirely unvested. The Career Shares may be converted to common stock only at separation of service from the Company and are subject to vesting as outlined in “Grants of Plan-Based Awards”.

2022—2024 performance period results: Performance Share achievement with respect to the 2022—2024 performance period was measured by Adjusted EBITDAR, weighted at 33%, consolidated Adjusted EBITDAR margin, weighted at 33%, and return on invested capital (“ROIC”), weighted at 33%. Achievement was based on three separate twelve-month performance periods, with possible achievement ranging from 0% to a maximum of 200%. Company performance for the three twelve-month performance periods resulted in a blended payout at 122%.

PERQUISITES AND OTHER BENEFITS

We provide our NEOs with perquisites that we believe are reasonable, competitive and consistent with our overall executive compensation program.

Our NEOs are eligible to participate in our benefit plans, including our 401(k) plan and medical, vision and dental insurance. In addition, our senior management members and our non-employee directors are eligible to participate in our deferred compensation plan on the same terms as other eligible management-level employees. We provide our NEOs with additional life insurance coverage compared to what is generally made available to our other employees, and our CEO uses our corporate aircraft for limited personal use. See “Summary Compensation Table”.

STOCK OWNERSHIP GUIDELINES

We believe having a meaningful ownership stake in the Company is an important tool to align interests across all stockholders. Our guidelines require stock ownership based on a multiple of the participant’s base salary, as follows:

|  | Multiple of Base Salary
Executive Chairman |  |  |  | 5x |
Chief Executive Officer |  |  |  | 5x |
Chief Financial Officer, Chief Operating Officer, Chief Administrative Officer, and General Counsel |  |  |  | 3x |

Our non-employee director stock ownership guidelines require that each independent Board member hold Company stock at least equal to five times the annual cash retainer received by the director.

Under our clawback policy, we will, under certain circumstances, recoup the value of cash, equity or equity-linked incentive compensation tied to performance metrics and paid to our NEOs. In the event of any required restatement of our financial statements, we will seek to recover from our Section 16 officers incentive-based compensation (as defined in the policy) to the extent such compensation exceeds what would have been paid had it been based on the financial statements as restated.

Our equity award agreements also provide that, in addition to being subject to the Company’s clawback policy, the awards may be subject to forfeiture or recoupment if the award recipient violates restrictive covenants or company policies or otherwise engages in activity that has caused, or could reasonably be expected to cause, significant economic or reputational harm to the Company.

We will administer our clawback policy consistently with the requirements of Securities Exchange Act “Exchange Act” Rule 10D-1 and any related rules or regulations adopted by the SEC or the NYSE or other applicable laws.

ANTI-HEDGING POLICY

Our NEOs are subject to Company policies that prohibit them from entering into hedging or monetization transactions involving the Company’s securities, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, exchange funds or otherwise.

COMPENSATION COMMITTEE REPORT

We have reviewed and discussed with management the Compensation Discussion and Analysis. Based on our review and discussions, we recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement.

Actual award amount is measured by Adjusted EBITDAR after corporate expense and achievement of CSR initiatives and includes a discretionary component as approved by the Board. “Threshold” represents achieving a performance level that is 80% of the target amount; “Target” represents achieving 100% of the target amount; and “Maximum” represents achieving 120% or more of the target amount.

(2) | Represents Career RSUs granted pursuant to our Career Shares Program under our Stock Incentive Plan.

To receive any payout under the Career Shares Program, grantees must be at least 55 years of age and must have been continually employed by us for a minimum of ten years. Retirement after ten years of service will entitle a grantee to 50% of his Career RSUs. The amount increases to 75% after 15 years and 100% following 20 years of employment. In the event of a grantee’s death or permanent disability, or following a change in control of the Company, the grantee will be deemed to have attained age 55, and the Career RSUs will immediately vest and convert into shares of our common stock based on the grantee’s years of continuous service through the date of the qualifying event.

(4) | Each Performance Share represents a contingent right to receive up to a maximum of two shares of our common stock, subject to satisfaction of certain performance metrics. The Performance Shares are subject to forfeiture and other terms and conditions contained in the award agreement and our Stock Incentive Plan.

(5) | Career RSUs are based on the base salary of the participant in effect on December 31 of the immediately preceding year and the closing stock price of our common stock on January 2 or, if January 2 is not a business day, then the next business day.

(6) | Represents the aggregate grant date fair value of the 2024 awards, determined in accordance with ASC 718. Amounts reported for Performance Shares assume that the performance metrics were achieved at the target performance level.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Under the terms of our 2000 MIP, Change in Control Plan (“CIC Plan”) and our equity incentive plans, including the individual award agreements under our equity incentive plans, our NEOs may be entitled to payments, enhanced vesting and other benefits upon their termination of employment or a change in control of the Company. The description of the plans is qualified by reference to the complete text of the plans, which have been filed with the SEC. We have not entered into any severance agreements with our currently serving NEOs.

The following table sets forth the estimated payments, enhanced vesting entitlements and other benefits that would be made to each of our NEOs upon voluntary termination, involuntary termination—not for cause, involuntary termination—for cause, a qualifying termination in connection with a change in control, and death or permanent disability. The payments would be made pursuant to the plans identified in the preceding paragraph. The information set forth in the table assumes:

| • |  | The termination event occurred on December 31, 2024 (the last business day of our last completed fiscal year);

| • |  | The price per share of our common stock on the date of termination is $72.54 per share (the closing market price of our common stock on December 31, 2024, the last trading day in 2024);

| • |  | For purposes of the short-term/annual awards under the 2000 MIP, the NEO has earned and is paid his target bonus, as applicable, under the 2000 MIP;

| • |  | All payments are made in a lump sum on the date of termination;

| • |  | The vesting of all unvested stock options, time-based RSUs, Performance Shares and Career RSUs held by the executives (treating as unvested those Performance Shares that settled based on the Compensation Committee’s subsequent determination of 2024 performance) is immediately accelerated in full upon a change of control pursuant to discretionary authority of the plan administrator granted pursuant to the applicable plan (if not otherwise accelerated pursuant to the terms of the applicable award agreements, terms of the CIC Plan or pursuant to “long service” benefits);

| • |  | The portion of in-the-money stock options and other equity awards that are subject to accelerated vesting in connection with the termination are immediately exercised and the shares received upon exercise (or upon settlement in the case of time-based RSUs, Performance Shares and Career RSUs) are immediately resold at the assumed price per share of our common stock on the date of termination; and

| • |  | Any vested Career RSUs held by the executives are immediately resold at the assumed price per share of our common stock on the date of termination.

CEO PAY RATIO

The 2024 annual total compensation of Mr. Smith, our President and CEO, was $11,495,978, as reported in the Summary Compensation Table. Based on the methodology described below, we determined that the median employee in terms of total 2024 compensation of all Company employees (other than Mr. Smith) received an estimated $37,755 in annual total compensation for 2024. Therefore, the estimated ratio of 2024 total compensation of Mr. Smith to the median employee was 304 to 1. The pay ratio provided is a reasonable estimate calculated in a manner consistent with SEC rules.

We took the following steps to identify our median employee and determine median employee compensation:

| • |  | We identified our employee population as of December 31, 2024, which consisted of approximately 16,191 full-time and part-time employees.

| • |  | With respect to employees other than Mr. Smith, we used a “base salary” for 2024, which consisted of base cash salary for salaried employees and cash compensation paid at the applicable hourly rate, plus any applicable cash tip income reported, for non-salaried employees. We then identified the median employee whose compensation we believe best reflects the Company’s median employee 2024 compensation.

| • |  | We then determined the median employee’s 2024 total compensation using the approach when calculating our NEOs’ compensation, as reported in the Summary Compensation Table. The median employee’s 2024 total compensation included all cash compensation and Company matching contributions to the employee’s 401(k) account.

The median salary increased from $35,904 in 2023 to $37,755 in 2024. We experienced an increase in the number of employees from 16,032 as of December 31, 2023 to 16,191 as of December 31, 2024, or an increase of 159 year over year.

Financial Performance Measures
We structure our pay principles to balance achievement of short- and long-term goals with a focus on Company performance, as described in “
Compensation Discussion and Analysis
”. We view the following financial performance measures as the most important financial performance measures in determining compensation actually paid to our CEO and other NEOs for the most recently completed fiscal year:

| • |  | Adjusted EBITDAR;

| • |  | Consolidated Adjusted EBITDAR margin; and

| • |  | Return on invested capital (“ROIC”).

Information Presented in the Pay versus Performance Table
Our pay principles are intended to promote Boyd Gaming’s philosophy of being innovative yet disciplined. We seek to align executive interests with all stakeholders by setting performance measures that provide a clear path to achieving long-term value. Because the Company generally places emphasis on long-term performance, compensation actually paid as disclosed in the table above may not specifically align with achievement of performance measures for a particular year.
Compensation Actually Paid and Cumulative Total Shareholder Return (“TSR”)
As described in “
Compensation Discussion and Analysis
”, equity awards comprise approximately 60% of our CEO’s compensation awarded during the fiscal year. These awards consist of performance-based RSUs, time-based RSUs, and Career RSUs. Generally, time-based RSUs and performance-based RSUs do not vest during the year awarded. Subject to certain exceptions as noted above, the degree to which career shares may be distributed at retirement depends on the satisfaction of certain age and service criteria. The following graph demonstrates the relationship between compensation actually paid and cumulative TSR considering the Company’s emphasis on long-term equity awards.

Compensation Actually Paid and Adjusted EBITDAR
We believe Adjusted EBITDAR is the most important indicator of our financial performance, which is indicated by the relative significance it bears in achievement of short- and long-term incentives. See “

PROPOSAL 2—RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Deloitte and Touche, LLP (“Deloitte”) has served as our independent registered public accounting firm since 1981 and has been appointed by the Audit Committee to continue as our independent registered public accounting firm for the year ending December 31, 2025.

If our stockholders do not ratify the selection of Deloitte as our independent registered public accounting firm, the Audit Committee will review its selection of auditors, and a change in its selection may or may not occur. Even if the appointment is ratified, the Audit Committee reserves the right to select a different independent registered public accounting firm at any time during the fiscal year without resubmitting the matter to stockholders for ratification.

A Deloitte representative is expected to be present at the Annual Meeting and will have an opportunity to make a statement and respond to appropriate questions.

The Audit Committee considered whether Deloitte’s provision of any professional services other than its audits of our annual financial statements and the effectiveness of our internal controls over financial reporting, reviews of quarterly financial statements and other audit-related services, is compatible with maintaining its independence.

Audit and Non-Audit Fees

The following table sets forth the aggregate fees billed by Deloitte for the audits and other services provided to the Company for fiscal years 2024 and 2023.

|  | 2024 |  |  | 2023 |
Audit Fees(1) |  | $ | 4,030,000 |  |  | $ | 4,061,000 |
Audit-Related Fees(2) |  |  | 1,012,000 |  |  |  | 1,009,000 |
Tax Fees(3) |  |  | 208,000 |  |  |  | 248,000 |
All Other Fees |  |  | — |  |  |  | — |
Total |  | $ | 5,250,000 |  |  | $ | 5,318,000 |

(1) | Audit fees represent fees for professional services provided in connection with the audit of our consolidated financial statements, the review of our quarterly financial statements and the audit of the effectiveness of our internal controls over financial reporting, including professional services relating to our corporate transactions and acquisitions.

(2) | Audit-related fees consist primarily of services provided in connection with our regulatory audits, consulting on technical accounting matters and certain other audit-related consultation services.

(3) | Tax fees consist primarily of tax consultation and planning fees and tax compliance services, including services provided in connection with certain federal and state tax matters, cost segregation services, transaction support and Internal Revenue Service examination support services.

Audit Committee Pre-Approval of Audit and Non-Audit Services: The Audit Committee has adopted a policy for the pre-approval of all audit and permissible non-audit services provided by our independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. Under the policy, pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is subject to a specific budget. In addition, the Audit Committee may also pre-approve particular services on a case-by-case basis. The Audit Committee has delegated its pre-approval authority to the Audit Committee chair. The chair is required to report any decisions to the Audit Committee at the next scheduled Committee meeting. All services provided by Deloitte in fiscal year 2024 were approved by the Audit Committee.

Our Board of directors recommends you vote FOR ratification of the appointment of Deloitte as the Company’s independent registered public accounting firm for the fiscal year 2025.

PROPOSAL 3—ADVISORY VOTE ON EXECUTIVE COMPENSATION

The Company is providing stockholders with the opportunity to vote to approve, on a nonbinding, advisory basis, the compensation of our NEOs as disclosed in this proxy statement in accordance with the compensation disclosure rules of the SEC, as required by Section 14A of the Exchange Act and related SEC rules (a “say-on-pay” proposal). The vote on this resolution is not intended to address any specific element of compensation but rather relates to the overall compensation of our NEOs as described in this proxy statement in accordance with the SEC’s compensation disclosure rules. Our Board determined that the Company will hold an advisory stockholder vote on the compensation of our NEOs every year. Following the stockholders’ vote on Proposal 3 at the Annual Meeting, the next say-on-pay proposal will be held at the Company’s 2026 Annual Meeting, and an advisory vote on the frequency of say-on-pay proposals will be held no later than the Company’s 2029 Annual Meeting.

As described in “Compensation Discussion and Analysis,” the compensation programs for our NEOs are designed to promote the Company’s long-term strategy. Accordingly, the compensation of our NEOs is based in large part on our success and achievements as assessed by our Board.

The Compensation Committee believes the Company’s executive compensation programs have been effective at recognizing the achievement of sound financial performance and accomplishment of strategic, long-term transformative corporate events.

Our Board and Compensation Committee value the opinions of our stockholders who supported our compensation programs for our NEOs at the 2024 Annual Meeting with approximately 95.96% of votes cast. We are committed to ongoing engagement with our stockholders on executive compensation and corporate governance issues in addition to conducting periodic advisory votes on executive compensation.

Accordingly, we ask our stockholders to vote on the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the Named Executive Officers, as disclosed in the Company’s Proxy Statement for the 2025 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure.”

As an advisory vote, this resolution is not binding on the Company, our Board or our Compensation Committee. However, we believe that it is important for our stockholders to have an opportunity to express their views regarding our executive compensation philosophy, our compensation policies and programs, and our decisions regarding executive compensation. The Compensation Committee will consider the outcome of this advisory vote when making future compensation decisions regarding our NEOs.

The Board of directors recommends you vote FOR the approval, on an advisory basis, of the compensation of our named executive officers, as disclosed in this proxy statement.

PROPOSAL 4—REPORT ON SMOKEFREE POLICY

Trinity Health, Americans for Nonsmokers’ Rights Foundation, and School Sisters of Notre Dame Collective Investment Fund (collectively, the “proponents”) have notified the Company that they intend to present the following proposal for consideration at the Annual Meeting. The proponents have presented the proposal and supporting statements set forth below, and we are presenting the proposals and the supporting statements as they were submitted to us.

Although we do not support certain of the statements contained in the proposal and the supporting statements, we have limited our response to the most important points and have not attempted to address all the statements with which we disagree. The address and stock ownership of all proponents will be furnished by our Corporate Secretary to any person, orally or in writing as requested, promptly upon receipt of any oral or written request.

Resolved: Shareholders request the Board of Directors commission and disclose a report on the potential cost savings through the adoption of a smokefree policy for Boyd Gaming properties. The report should be prepared at reasonable cost, omitting confidential and proprietary information.

Whereas:

The U.S. Surgeon General released a landmark report in 2006 stating that there is no safe level of exposure to secondhand smoke. Tobacco use and secondhand smoke exposure kill nearly 500,000 Americans annually.1 For the gaming industry workers on casino floors, largely people of color and women, such exposure can deepen existing disparities in health outcomes.

While our Company may make efforts to address indoor air quality, the American Society of Heating, Refrigerating and Air-Conditioning Engineers states: “There is no currently available or reasonably anticipated ventilation or air cleaning system that can adequately control or significantly reduce the health risks of environmental tobacco smoke to an acceptable level.”2

As independent researchers C3 Gaming found in analyzing revenue performance in several competitive casino markets, smokefree casinos, for the first time, generated more revenue: “Data from multiple jurisdictions clearly indicates that banning smoking no longer causes a dramatic drop in gaming revenue. In fact, non-smoking properties appear to be performing better than their counterparts that continue to allow smoking.”3

There are potential business risks to allowing indoor smoking in Boyd Gaming properties: higher employee health insurance premiums (when compared with casinos that don’t permit indoor smoking); greater maintenance costs; loss of a significant number of potential visitors who won’t visit a casino due [sic] exposure to secondhand smoke. A recent Gallup survey found the rate of adult cigarette smoking to be 11%, the lowest in 80 years.4

Shareholders have no guidance as to the costs our Company is bearing for continuing to allow indoor smoking. The Company has not disclosed the social and environmental costs and risks imposed on its stakeholders.

Parx Casino’s Chief Marketing Officer told the Play Pennsylvania website in February 2023 that since the casino went smokefree, Parx has seen a positive effect on the health and morale of employees, with no increase in health insurance premiums: “Frankly, we are starting to see health costs go down….What’s been interesting to me, is a lot of our smoking guests have actually said things like, ‘I never realized how smoky and annoying it was. I really don’t mind walking 50 feet out to the smoking patio.”5

Speaking at a recent industry conference, a senior official of Foxwoods, the nation’s largest resort casino which has been smoke-free since reopening after the pandemic, said that Foxwoods’ surveys found strong support for ending indoor smoking.6

New customer preferences require an examination of the status quo in which smoking is allowed in gaming properties. We believe our Company could enhance its safety initiatives by conducting the report our proposal requests.

Board Recommendation

The Board of Directors recommends you vote AGAINST this proposal.

The proposal asks for a report on implementing a smoke-free policy at our properties, but we believe this represents a first step in imposing a unilateral smoke-free policy at Boyd Gaming, regardless of our competitors’ actions. We recommend that you vote against the proposal confident that we are focused on these issues, just as we are with all matters related to maintaining excellent customer service and team member relationships. Nevertheless, we do not believe that the proposal addresses this issue with an appropriate level of nuance and consideration.

Effectively Balancing Interests

Customer experience is at the forefront of our decision-making, as that is how we attract and maintain our loyal customer base and in turn enhance stockholder value. Our team members play an integral part in that by delivering excellent customer service. We value our relationships with our team members and our customers, and we keep a steady pulse on feedback received from all stakeholders across our properties and beyond.

The smoking policies at each of our properties are individually tailored and take into account a wide range of business factors, including the tastes and preferences of customers in those locations, local practices and regulations, competitor policies, the effectiveness of airflow technology solutions, and potential impacts of alternative approaches. Balancing these considerations is a complex issue, and the policies that our management implements at each property directly impact our customer base and, by extension, our customer loyalty and financial performance. Recently, our customer experience was negatively impacted by smoking bans in our Midwest and South markets, and we experienced negative customer churn as a result, which carried negative implications for our results and therefore investor returns.

Our management has determined that adopting a unilateral property-wide smokefree policy would have significant competitive implications, as customers who prefer to incorporate smoking into their gaming experience could consider patronizing a competitor. As noted above, we previously suffered negative results in markets subject to smoking bans. Given the overwhelming number of competitors that permit smoking, unilateral implementation of the shareholder proposal would place Boyd Gaming at a significant competitive disadvantage, adversely impact gaming revenues and consequently reducing stockholder value. We focus on the customer experience at each of our properties and believe the inflexible policy in this proposal would significantly hinder our ability to customize that approach to best serve our customers.

We continue to balance all stakeholder interests, but we also continue to believe such business decisions are best left to our management team.

Continuously Working to Enhance Customer Experience

We have a robust governance structure with an active board of directors, experienced executive oversight and subject matter experts who analyze our ongoing management of properties and ultimately make decisions in a manner that is appropriate for the Company, our customers and you—our shareholders. We continually work on ways to maintain and enhance customer and team member experience. The various impacts of our smoking policies are only one of a myriad of considerations we constantly assess. You have entrusted us with making decisions that are in your best interests as the owners of our Company, which we are committed to doing. We believe our performance demonstrates that.

Accordingly, the Board of directors recommends you vote AGAINST this shareholder proposal.

Who will vote my shares if I specify how my shares are to be voted?

Marianne Boyd Johnson and William R. Boyd are both directors of the Company and were named by our Board as proxy holders. They will vote all proxies, or record an abstention or withholding, in accordance with the directions on the proxy card. For a discussion regarding how the proxy holders will vote proxies if no direction is given, please see “What if I do not specify how my shares are to be voted?”

What if I do not specify how my shares are to be voted?

If you indicate that you wish to vote as recommended by our Board or if you execute and return your proxy card but you do not provide instruction with respect to any or all proposals to be acted upon at the Annual Meeting, your shares will be voted in accordance with the recommendations of our Board. Your proxy will be voted “FOR” the election of each of the director nominees named in this proxy statement; “FOR” Proposal 2; “FOR” Proposal 3; “AGAINST” Proposal 4; and as the proxy holders deem advisable on other matters that may properly come before the Annual Meeting.

If you are a beneficial owner of our common stock and you do not provide instructions to your bank, broker or other holder of record on how to vote your shares, your bank, broker or other holder of record may vote your shares in its discretion only on Proposal 2. Your bank, broker or other holder of record may not vote your shares with respect to Proposals 1, 3 or 4 without instructions. For a discussion regarding the difference between stockholders of record and beneficial owners, please see “What is the difference between holding shares as a stockholder of record and as a beneficial owner?”

Currently, no matter is expected to be considered at the Annual Meeting other than the proposals set forth in the accompanying Notice of Annual Meeting of Stockholders (“Notice of Annual Meeting”). However, if any other matters are properly brought before the Annual Meeting for action, it is intended that the shares of our common stock represented by proxies will be voted by the persons named as proxy holders on the proxy card in accordance with their discretion on such matters.

Why did I receive an Internet Availability Notice instead of a full set of the proxy materials?

We are pleased to take advantage of the SEC rules that allow companies to furnish their proxy materials via the Internet. Accordingly, we sent to our stockholders the Internet Availability Notice regarding Internet availability of the proxy materials for this year’s Annual Meeting. Other stockholders who have previously requested a paper copy of the proxy materials by mail will receive a paper copy of the proxy materials rather than the Internet Availability Notice. Instructions on how to access the proxy materials over the Internet or to request a paper copy can be found in the Internet Availability Notice. In addition, stockholders may request to receive proxy materials in printed form by mail or electronically by e-mail on an ongoing basis by submitting a request to us at www.boydgaming.com/proxymaterials; by mail at Boyd Gaming Corporation, 6465 South Rainbow Boulevard, Las Vegas, Nevada 89118, Attn: David Strow, Vice President of Corporate Communications; via toll-free telephone: 800-695-2455, Attn: David Strow; or via e-mail: davidstrow@boydgaming.com. A stockholder’s election to receive proxy materials by mail or e-mail will remain in effect until the stockholder terminates it.

What is “householding” and how does it work?

Under SEC rules, we may deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of these documents was delivered. If you prefer to receive separate copies of the proxy statement or annual report, contact Broadridge Financial Solutions, Inc. by calling 1-866-540-7095 or in writing at 51 Mercedes Way, Edgewood, New York 11717, Attention: Householding Department.

In addition, if you currently are a stockholder who shares an address with another stockholder and would like to receive only one copy of future notices and proxy materials for your household, you may notify your broker if your shares are held in a brokerage account or you may notify us if you hold registered shares. Registered stockholders may notify us by contacting Broadridge Financial Solutions, Inc. at the above telephone number or address.

##### Table of Contents

Can I vote my shares by filling out and returning the Internet Availability Notice?

No. The Internet Availability Notice does, however, provide instructions on how to vote your shares.

How do I attend the Annual Meeting?

This year’s Annual Meeting will be held entirely online via audio webcast. You may attend, vote and ask questions at the Annual Meeting by following the instructions provided in the proxy materials to log in to http://www.virtualshareholdermeeting.com/BYD2025. You will be asked to provide the 16-digit control number from your proxy card, Internet Availability Notice or voting instruction form.

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

If your shares are registered directly in your name with our transfer agent, EQ Shareowner Services, you are considered, with respect to those shares, the “stockholder of record.” In such case, an Internet Availability Notice or, if you had previously requested the delivery of paper copies, the Notice of Annual Meeting, this proxy statement and our 2024 Annual Report to Stockholders have been sent directly to you.

If your shares are held in a stock brokerage account or by a bank or other holder of record, you are considered the “beneficial owner” of shares held in street name. In such case, an Internet Availability Notice or paper copies of the Notice of Annual Meeting, this proxy statement and our 2024 Annual Report to Stockholders should have been forwarded (or otherwise made available) to you by your broker, bank or other holder of record who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker, bank or other holder of record on how to vote your shares by following their instructions for voting.

Can I change my vote after I submit my proxy or voting instructions?

Yes. You may revoke your proxy at any time before it is voted at the Annual Meeting by:

| • |  | properly submitting a subsequent proxy in one of the manners authorized and described in this proxy statement (such as via the Internet, by telephone or by mail pursuant to the voting procedures described above under “How do I vote?”); or

| • |  | giving written notice of revocation to our Corporate Secretary prior to or at the Annual Meeting; or

| • |  | attending and voting at the virtual Annual Meeting.

Your attendance at the virtual Annual Meeting will not have the effect of revoking your properly submitted proxy unless you follow one of the procedures referenced above. Any written notice revoking a proxy should be sent to the Company at 6465 South Rainbow Boulevard, Las Vegas, Nevada 89118, Attention: Corporate Secretary and must be received before voting is closed at the Annual Meeting.

If you are a beneficial owner of our common stock, please follow the instructions provided by the record holder (e.g., your bank or broker) regarding how to change or revoke your voting instructions.

What are “broker non-votes”?

“Broker non-votes” are shares as to which a broker or nominee does not vote or has indicated that it does not have discretionary authority to vote. Under NYSE rules, certain matters submitted to a vote of stockholders are considered by NYSE to be “routine” items upon which brokerage firms may vote in their discretion on behalf of their customers if such customers have not furnished voting instructions within a specified period of time prior to the Annual Meeting. For those matters which NYSE determines to be “non-routine,” brokerage firms that have not received instructions from their customers do not have discretion to vote. Consistent with applicable NYSE rules, with respect to the proposals set forth in this proxy statement, only Proposal 2 is considered a “routine” matter. Proposals 1, 3 and 4 are each considered a “non-routine” matter, and therefore broker non-votes may exist in connection with Proposals 1, 3 and 4. Neither our Amended and Restated Articles of Incorporation, our Amended and Restated Bylaws, nor Nevada corporate statutes specifically address the treatment of broker non-votes and abstentions.

##### Table of Contents

What is a quorum, and how is it determined?

A quorum must be present for business to be properly conducted and the vote of stockholders to be valid at the Annual Meeting. The presence at the virtual meeting, whether personally or by proxy, of the holders of a majority of shares of our common stock issued and outstanding as of the record date is necessary to constitute a quorum. Shares represented at the meeting, whether personally or by proxy but not voted will nevertheless be counted for purposes of determining the presence of a quorum. Accordingly, abstentions and broker non-votes will be treated as shares that are present and entitled to vote for purposes of determining the presence of a quorum. If we do not have a quorum, we will be forced to reconvene the Annual Meeting at a later date.

How many votes are required to approve the proposals?

Assuming a quorum is present, the required votes to approve each proposal are as follows:

| • |  | Proposal 1—a plurality of the votes cast is required for the election of directors. This means that the eight director nominees receiving the greatest number of “FOR” votes will be elected to the board of directors. You may vote “FOR” or “WITHHELD” with respect to the election of directors. Only votes “FOR” are counted in determining whether a plurality has been cast in favor of a director. Withheld votes and broker non-votes are not counted for purposes of the election of directors.

If the election of directors under Proposal 1 is uncontested, our Corporate Governance Guidelines provide that a director must tender his or her resignation to the Board if the number of votes withheld for his or her election exceeds the number of affirmative votes cast in favor of his or her election. The Board must then consider whether to accept such director’s resignation but is not required to accept the resignation as set forth in the Corporate Governance Guidelines.

| • |  | Proposal 2—the number of affirmative votes cast in favor of Proposal 2 must exceed the number of votes cast against it for approval of the ratification of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025. Abstentions are not counted for purposes of Proposal 2, and no broker non-votes are expected on this proposal.

| • |  | Proposal 3—the number of affirmative votes cast in favor of Proposal 3 must exceed the number of votes cast against it for the approval, on an advisory basis, of the executive compensation of our NEOs. Broker non-votes and abstentions are not counted for purposes of Proposal 3.

| • |  | Proposal 4—the number of affirmative votes cast in favor of Proposal 4 must exceed the number of votes cast against it for the approval, on an advisory basis, of the commissioning of a report on the effects of a company-wide non-smoking policy. Broker non-votes and abstentions are not counted for purposes of Proposal 4.

Who will count the votes?

Votes cast by proxy or in person will be tabulated by the Inspector of Elections for the Annual Meeting, Broadridge Financial Solutions, Inc. The Inspector of Elections will also determine whether a quorum is present.

Where can I find voting results of the meeting?

We will disclose final voting results on a Current Report on Form 8-K filed with the SEC within four business days after the Annual Meeting.

Who pays for the cost of this proxy solicitation?

This proxy solicitation will be conducted by mail, and we will bear all associated costs. These costs will include the expense of preparing and mailing the Internet Availability Notice and the proxy solicitation materials referenced therein for the Annual Meeting and reimbursements paid to brokerage firms and others for their expenses incurred in forwarding such materials to beneficial owners of our common stock. We may conduct further solicitation personally, telephonically, via the Internet or e-mail, or by facsimile or mail through our officers, directors and employees, none of whom will receive additional compensation for assisting with the solicitation.
