| **Message from Our Chairman and <br>Our Presiding Independent Director** | **Message from Our Chairman and <br>Our Presiding Independent Director** |
| <br>![IBP-Logo.gif](ibp-20260408_g3.gif) | Installed Building Products, Inc. ("IBP" or the "Company) achieved record annual net revenue, net income, and net income per diluted share in 2025, demonstrating operational excellence and exceptional execution under challenging new residential end market conditions. The Company successfully integrated prior acquisitions and expanded its national presence by acquiring an additional 11 businesses, including bolt-ons. IBP's Board of Directors ("Board") remains confident in the ongoing execution of the Company's established acquisition strategy, emphasizing maximization of returns on invested capital and careful consideration of both strategic business alignment and cultural compatibility with IBP. The Company views its employed labor force as a key competitive advantage and an essential component of the value delivered to customers. <br>Despite headwinds in our new residential end markets, the Company showed resilience and finished 2025 with record annual revenue of $3.0 billion, net income of $265 million, and net income per diluted share of $9.71. Given the variable demand backdrop across our end markets throughout the year, we remained focused on managing operating costs and improving profitability. As a key to our success, autonomy is extended to the managers across our over 250 branches nationwide. With leadership on all levels motivated to drive improvement, quarter-over-quarter and year-over-year, the Board continued to provide valuable oversight of business challenges and strategic growth opportunities such as acquisitions and new product offerings.<br>Our 2025 acquisitions boosted financial results, offsetting organic sales challenges and increasing our geographic, product, and market diversity. We have a long track record of consolidation and the insulation installation industry remains fragmented, offering further attractive acquisition opportunities in areas where we have a limited presence. Additionally, expanding products and end markets offers strategic growth paths. The Board and executive team continue to view acquisitions as a top priority for the Company and an attractive use of cash. <br>Our ability to make acquisitions with existing liquidity is substantial and the January 2026 completion of a private offering of $500 million senior unsecured notes further expanded our ability to manage industry cycles and pursue strategic growth. In 2025, our rigorous financial discipline resulted in a return on invested capital above 20%, which was consistent with the returns realized over the previous three years. We apply that same disciplined approach to all forms of capital allocation and in 2025, we returned a total of $261 million in cash to shareholders in the form of dividends and share buybacks.<br>We view the IBP business model and our competitive position as both fundamentally appealing and stable. Our employees, especially those who install our carefully selected products, are central to the value we deliver to residential and commercial customers. At IBP, we work diligently to attract and have successfully retained installers. Because our work is labor-intensive and often tailored to specific projects with unique building code requirements, we consider the human element in our operations to be crucial. We regularly monitor the latest advances in  |

**Business Overview** 

We have three operating segments consisting of installation, distribution and manufacturing. Our primary business is the installation of building products, mainly insulation, in residential and commercial buildings. We also install a diversified range of other building products including waterproofing, fire-stopping, fireproofing, garage doors, rain gutters, window blinds, shower doors, closet shelving, mirrors and other products, which provide cross-selling opportunities to supplement our insulation installation business. We offer our services from our network of over 250 branch locations serving the 48 continental United States and the District of Columbia.

Our distribution platform consists of three regional distributors. AMD Distribution Services has ten locations serving the Midwest and Mountain West and distributes spray foam insulation, metal building insulation, residential insulation, mechanical and fabricated Styrofoam insulation and accessories. Central Aluminum Supply and Central Aluminum Supply of North Jersey have six locations and distribute gutter supplies and accessories for construction projects across the Northeast and Mid-Atlantic. Insulation Supplies distributes various insulation products, including equipment and machines, in the Midwest.![IBP-Corporate-Map-Master_updated2026.jpg](ibp-20260408_g8.jpg)

We have two manufacturing operations. Advanced Fiber Technology operates in Bucyrus, Ohio and produces cellulose insulation and specialty industrial fibers. Advanced Fiber Technology's primary product, cellulose insulation, consists primarily of wastepaper and helps reduce greenhouse emissions by reducing the wastepaper decomposing in landfills which releases methane and carbon dioxide gases.

Ronda, North Carolina, manufactures cellulose-based insulation for homes, hydromulch for erosion control and composite materials used in industrial applications.

**Our Business Strategy** 

**Growth Strategy**

We are focused on diversifying our products and services, broadening our mix of end market exposure and expanding our geographic footprint. Our growth strategy includes acquisition of residential and commercial installers in new markets, acquisitions of businesses offering complementary products, introduction of new product offerings in existing markets, pursuit of new product categories in commercial markets, and expanding our multi-family sales in existing branches.

We have a demonstrated record of success for each of our growth strategies:

**• Product diversification** - Revenue from insulation installation services represented approximately 79% of our total revenues in 2015 compared to 58% in 2025.

**• End market diversification** - We have decreased our single family residential new construction end market exposure from 75% in 2015 to 55% in 2025.

**• Geographic expansion** - We have added over 150 branch locations since 2014.

**Capital Allocation Strategy**

Our capital allocation priorities include:

• Acquisitions, which contribute to our profitability and anchor our growth strategies of product, end market and geographic diversification, and

• Quarterly and annual variable dividends and opportunistic share repurchases, which provide direct returns to our stockholders.

In 2025, we acquired eleven businesses with revenues of approximately $64 million, which expanded our geographic presence in attractive housing markets. We returned $261 million to stockholders, including quarterly and variable dividends of $88 million and stock repurchases of $173 million.

**Acquisition Strategy**

In the 1990s, we began our acquisition strategy with the goal of creating a national platform and have since grown, by our estimate, to become one of the nation's largest installers of insulation in the residential new construction end market. Since 1999, we have successfully completed and integrated over 200 acquisitions, which have expanded our scale and market presence and diversified our product offerings and end market exposures. Our asset-light model generates substantial operating cash flow, which supports further acquisition growth. In 2025, we successfully acquired and integrated eleven businesses representing approximately $64 million in aggregate annual revenues.

1. In Q2 2022, we changed the criteria for how acquisitions are counted in the chart. Generally, acquisitions presented meet the following criteria: (1) we pay for goodwill; (2) business has a standalone location; (3) business name is projected to remain over the long term; and (4) purchase price greater than $0.5 million. The first acquisition that meets this criteria was completed in 1994. U.S. residential completions data based on U.S. Census Bureau in million units, left axis.

("Five Year Plan"), which is more fully described in *"Compensation Discussion & Analysis – Section 4- What We Paid in 2025 - 2025 Performance-Based Restricted Stock Awards – Five Year Plan*". The earned fair value was determined by multiplying the closing price of the Company's common stock on February 24, 2026 ($319.99) (the date of certification of the achievement of the performance metrics) by the number of shares awarded. The restricted stock vests in equal installments over two years, except for stock awarded under the Five Year Performance Share Award Plan ("Five Year Plan"), which vests on April 20, 2030, in each case, subject to continued employment.

 **Proposal 1 – Election of Directors**

Upon the recommendation of the Nominating and Corporate Governance Committee ("NCG Committee"), the Board has nominated and is submitting to a vote of our stockholders a proposal to elect Michael T. Miller, Marchelle E. Moore and Robert H. Schottenstein as Class I directors to serve for three-year terms. Each nominee's term runs until the 2029 Annual Meeting of Stockholders.

The NCG Committee and the Board evaluated the background, experience, qualifications, attributes and skills of each nominee, as well as the years of experience they have had working together on the Board and the knowledge of the Company's business, operations, strategy and risks they have developed as a result of such service. The NCG Committee and the Board also considered Board refreshment and each nominee's contributions to the Board and role in the operation of the Board as a whole. See "Director Qualifications," "Board Composition" and "Director Skills, Experience and Background" below.

Director nominees are expected to demonstrate leadership and to possess the highest professional and personal integrity, values and judgment. The NCG Committee and the Board have determined that each of our nominees possesses the skills, experience and perspectives, collectively with other directors, to comprise a well-rounded, highly effective Board of Directors, and have determined that the nominees add to the overall strength of the Board by bringing insights and practical wisdom based on their experience and expertise.

All of the director nominees currently serve on the Board. Each nominee has accepted the nomination and has agreed to serve if elected. If a nominee is unable to serve as a director, the Board may reduce the number of directors constituting the full Board or may choose a substitute nominee.

**Overview of the Board** 

Our directors are divided into three classes, as nearly equal in number as possible and designated Class I, Class II and Class III, with one class of directors elected annually for a three-year term and the other classes of directors continuing to serve for the remainder of their respective terms. Each director holds office until his or her successor is duly elected and qualified or until his or her earlier death, resignation, retirement, disqualification or removal.

|:---|:---|:---|
| **Class I** | **Class II** | **Class III** |
| &nbsp;&nbsp;&nbsp;&nbsp;• Michael T. Miller<br>&nbsp;&nbsp;&nbsp;&nbsp;• Marchelle E. Moore<br>&nbsp;&nbsp;&nbsp;&nbsp;• Robert H. Schottenstein | &nbsp;&nbsp;&nbsp;&nbsp;• Margot L. Carter<br>&nbsp;&nbsp;&nbsp;&nbsp;• David R. Meuse<br>&nbsp;&nbsp;&nbsp;&nbsp;• Michael H. Thomas | &nbsp;&nbsp;&nbsp;&nbsp;• Jeffrey W. Edwards<br>&nbsp;&nbsp;&nbsp;&nbsp;• Lawrence A. Hilsheimer<br>&nbsp;&nbsp;&nbsp;&nbsp;• Janet E. Jackson |

---

The number of directors constituting the Board is fixed from time to time by a majority vote of the directors then in office. Our Board of Directors has currently fixed the number of directors at nine. No decrease in the authorized number of directors will result in the removal of an incumbent director until that director's term expires. Vacancies may be filled by the Board. The NCG Committee and the Board periodically evaluate Board structure.

**Director Qualifications** 

Our NCG Committee is responsible for annually reviewing the qualifications for Board membership and identifying and assessing the appropriate skills of our directors and director candidates with a view toward ensuring that the Board is comprised of individuals whose backgrounds, skills, experience and expertise, when taken together, provide the Board with the ability to provide effective oversight of the Company and its operations, strategy and risk management.

In evaluating the suitability of director candidates, the NCG Committee considers evolving needs within the Board and evaluates the entirety of each director candidate's credentials. The NCG Committee considers numerous factors, including those set forth in the matrix below, in seeking to maintain a balance of experience and expertise. The NCG Committee reviews the matrix annually to determine if it is appropriate to add additional skill sets to the Board to meet evolving needs or if it is more appropriate to maintain those skills at the management level. The matrix assists the NCG Committee in determining whether a director candidate or a Board member possesses skills that may be valuable in light of current and anticipated strategic plans, operational requirements and risk challenges and in the long term interest of our stockholders. Each of our director nominees and continuing directors possess valuable skills and experience that are not reflected in the matrix.

The NCG Committee also considers whether a director candidate meets applicable criteria for independence and whether the individual will enhance the diversity of views and experiences available to the Board in its deliberations. If the nominee is a current director, the NCG Committee takes into account the director's individual contributions to the Board, the director's ability to work collaboratively and the effectiveness of the Board as a whole. No specific weight is assigned to any particular factor and, depending on the current and anticipated needs of the Board, some factors may weigh more or less heavily.

**Board Composition** 

In addition to the skills and expertise described above, the NCG Committee also seeks a broad spectrum of backgrounds among members of the Board. The Board is expected to represent a range of backgrounds and experience. The NCG Committee and the Board believe that these considerations are consistent with creating a Board that best serves the Company, our stockholders, our employees and our communities. The NCG Committee believes that our director nominees and continuing directors exhibit commitment to long-term value creation for our stockholders, outstanding personal and professional ethics, sound business judgment, strategic vision, leadership experience and an appreciation of different perspectives.

**Director Compensation** 

The Board of Directors annually reviews and determines the compensation of our non-employee directors, taking into account the recommendations of the Compensation and Human Capital Committee ("CHC Committee"). Our executive officers have no role in determining the amount or form of non-employee director compensation.

The Board and the CHC Committee consider current business and industry conditions and the director compensation paid within our peer group, which is the same peer group used in reviewing the compensation of our executives. The Board believes that non-employee director compensation should be competitive to ensure that we attract and retain qualified non-employee directors, and that compensation should include an equity component to align the long-term interests of our non-employee directors with those of our stockholders. The Board does not have a pre-established policy or target for allocation between cash and equity and determines the mix of compensation based on what it believes is most appropriate under the circumstances. In 2025, the CHC Committee engaged Meridian Compensation Partners, LLC, an independent executive compensation consulting firm ("Meridian"), to review our non-employee director compensation program and to conduct market comparisons similar to those performed for our executive officer compensation program. See *Compensation Discussion and Analysis –"Section 2 – How We Determine Pay – Our Process – 'Role of Compensation Consultants' and 'Competitive Positioning.'"* The CHC Committee intends to engage Meridian or a similar firm to review our director compensation program approximately every two years, unless the committee determines to have a more frequent review.

Annual equity awards are awarded on the date of the Annual Meeting of Stockholders, based on the closing market price of our common stock on that date. Directors appointed to the Board at other times during the year receive a pro rata equity award. Our 2023 Omnibus Incentive Plan provides that total cash and equity compensation to any individual non-employee director may not exceed $400,000 in any fiscal year.

Non-employee directors are entitled to reimbursement for their reasonable expenses to attend Board and committee meetings, but do not receive fees for meeting attendance. Directors who are employees of the Company receive no compensation for their service as directors. We maintain directors' and officers' liability insurance and have entered into indemnification agreements with each of our directors. We do not provide incentive awards or retirement plans for our non-employee directors.

1. The amounts in this column represent all earned retainers. Ms. Carter and Mr. Thomas agreed in advance to waive $10,000 and $4,300, respectively, in order to assist the Company in funding awards under our Foundation. The waived amounts were not included in this column.

2. Represents an annual grant of restricted stock having a fair value of $125,000 on the grant date (May 20, 2025), computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation-Stock Compensation ("FASB ASC Topic 718"), based on the closing price of our common stock ($161.18) on the grant date. The restricted stock awards vest on the earlier to occur of (i) the one year anniversary of the grant date, (ii) immediately prior to the annual meeting of the Company's stockholders occurring after the grant date, or (iii) the director's death, subject in the cases of (i) and (ii) to the director's continued service through the vesting date.

3. No director held stock options as of December 31, 2025.

**Director Stock Ownership Policy** 

Pursuant to our Stock Ownership Policy for Directors established by the Board and the CHC Committee to align each director's interests with the long-term interests of our stockholders, each non-employee director (and any employee director who is not otherwise subject to the Company's stock ownership policy for executive officers) is required to beneficially own our common stock having a fair market value equal to the greater of $425,000 or five times the annual non-employee director cash retainer (excluding committee and Presiding Independent Director retainers). If a director chooses to meet this requirement by holding vested or unvested shares of common stock granted in connection with our director compensation program, the shares are valued at the greater of the closing price on the grant date or on the date on which ownership is measured. If a director fails to meet the ownership requirement on a measurement date, the director is prohibited from selling any Company stock and 50% of any annual cash retainer (or, for an employee director, an equivalent amount from any annual cash bonus) will be paid in the form of stock in lieu of cash. Our directors who are executive officers are subject to our stock ownership policy for executive officers. See *Compensation Discussion and Analysis – "Section 5 – Other Compensation and Policies – Stock Ownership Policy."*

To meet the requirements of the Stock Ownership Policy for Directors, a director has five years from the date of his or her appointment or election, or if later, the date of an increase in the amount of stock required to be held. All of our non-employee directors meet the stock ownership requirement.

**Required Vote and Recommendation of the Board** 

The affirmative vote of a majority of the total votes cast at the Annual Meeting is required to approve the election of each nominee as a director, which means that the number of shares voted "FOR" a nominee must exceed the number of shares voted "AGAINST" the nominee. "ABSTAIN" votes and broker non-votes will not be counted as votes cast either "FOR" or "AGAINST."

Our Amended and Restated Bylaws provide that any incumbent director who fails to receive a majority of votes cast in an uncontested election is required to promptly tender his or her resignation to the Board, which will become effective only upon its acceptance by the Board. The NCG Committee will recommend to the Board whether to accept or reject the resignation, and the Board will act upon such resignation and publicly disclose its decision within 90 days from the date of the certification of the election results.

Unless otherwise instructed, the persons named as proxies will vote "FOR" each nominee.

**Board Structure and Responsibilities** 

Our business strategy, operations and risk management are overseen by our Board of Directors. Management is responsible for the day-to-day management of the Company's operations and risk exposure, with the Board providing oversight and independent business judgment on issues most important to the Company. The Board's responsibilities include oversight of:

• Business strategy and strategic planning;

• Mergers and acquisitions strategy;

• Strategic opportunities and risks;

• Strategic, operational and financial performance;

• Capital management;

• Compliance with legal and regulatory requirements;

• Integrity of financial statements and internal controls;

• Practices for identifying, managing and mitigating key enterprise risks, including cybersecurity risk;

• Management's performance and succession planning for key executives;

• Executive and non-employee director compensation;

• Human capital management, including employee development, retention, safety and welfare; and

• Corporate governance and sustainability matters, including our Environmental, Social and Governance ("ESG") programs and initiatives discussed below in *"Corporate Responsibility".* 

The Board and management regularly confer on emerging industry and macroeconomic trends, the Company's long-term strategic plans, key strategic initiatives and significant risks relating to our business. Elements of our strategy are discussed at every regular Board meeting, as well as Board committee meetings. The Board also annually discusses and approves our budget and capital allocation plans, which are linked to our strategic plans and priorities.

**Board Leadership Structure** 

Mr. Edwards serves as our President, Chief Executive Officer ("CEO") and Chairman. The Board has concluded that the Company and its stockholders are best served by not having a formal policy regarding whether the same individual should serve as both Chairman and Chief Executive Officer. This approach allows the Board flexibility to exercise its business judgment in determining the optimal leadership structure depending on the Company's particular needs and in light of prevailing circumstances. We have historically combined the positions of Chairman and Chief Executive Officer.

The NCG Committee annually assesses the Company's corporate governance practices, which includes a review of our Board leadership structure and whether combining or separating the roles of Chairman and CEO is in the best interests of our stockholders. The NCG Committee currently is of the view that it is in our stockholders' best interests for Mr. Edwards to serve in a combined role. The Board believes that having Mr. Edwards serve as CEO and Chairman fosters an important unity of leadership between the Board and management that is subject to effective oversight by the Presiding Independent Director and other independent Board members. The Board believes that it benefits from the unique knowledge, insight and perspective that Mr. Edwards has gained during his more than 30 years in the industry, and that Mr. Edwards' in-depth knowledge of the Company and his extensive industry expertise makes him particularly qualified to lead Board discussions. The Board has also considered that Mr. Edwards has demonstrated exceptional leadership and vision necessary to lead the Board and the Company in challenging industry and economic environments, has demonstrated a commitment to advancing a culture of corporate responsibility and employee well-being, and, the Board believes, is viewed by our customers, stockholders, suppliers and business partners as a leader in our industry.

| <u>[**Table of Contents**](#i4430d499364a412791c1ca0d068409f9_10)</u> | **Corporate Governance** |

---

Based on the demonstrated success of our structure, both in terms of the functioning of the Board and the growth and performance of the Company, as well as the continued benefit of retaining Mr. Edwards' strategic perspective in the position of Chairman, the Board believes that having a combined position is the appropriate leadership structure for the Company at this time, and allows the Board to conduct its business in the most effective manner.

To support our leadership structure, the Board has established a Presiding Independent Director position to ensure independent oversight of management and flow of information and interactions among the Board, management and other Company personnel. Our Presiding Independent Director is elected annually by the independent directors. Ms. Carter, a director since 2014, currently serves as our Presiding Independent Director. Ms. Carter works with management to determine information to be provided to the Board, provides input on agenda items for Board and committee meetings, chairs regular executive sessions of the independent directors and serves as a liaison between management and the Board, as well as among independent directors. She regularly attends the meetings of all Board committees. The Board further exercises independent oversight through executive sessions of the independent directors after every regular Board meeting without the presence of management.

The Board believes that having a combined Chief Executive Officer and Chairman position, together with a Presiding Independent Director and a Board comprised of 78% independent directors supported by strong corporate governance practices, provides the best leadership structure for our Company at the present time. The Board recognizes that no leadership model is appropriate for all companies at all times and will continue to evaluate our leadership structure to choose the appropriate structure that it believes is in the best interest of our stockholders.

**Corporate Governance Guidelines** 

Our Corporate Governance Guidelines govern the structure of our Board and the conduct of our directors. The Corporate Governance Guidelines cover topics such as the role and responsibility of the Board, Board composition and structure (including size, independence, qualifications, conflicts of interest and leadership structure), conduct of board meetings, board committees, expectation of directors, ethical conduct, board evaluations and limitations on outside directorships.

We regularly review and update our Corporate Governance Guidelines in response to changing regulatory requirements and best practices. The experience of our directors on other public company boards also provides valuable insight into emerging corporate governance practices.

**Succession Planning** 

The retention and development of highly qualified leadership talent is critical to our continued success. The Board and the NCG Committee oversee CEO and senior management succession planning and leadership development at least annually. During its annual review, the Board and our Chief Executive Officer and Chief Financial Officer discuss recommendations of potential successors for our CEO and other senior management positions and the development of potential leadership talent within the Company. The Board reviews management succession planning for both long-term ordinary course scenarios as well as short-term contingency planning scenarios in the event of an emergency or other unanticipated event. Planning includes development of talent within the organization as well as planning to hire from outside the organization if circumstances warrant.

**Cybersecurity Oversight** 

The Board considers cybersecurity risk to be a critical part of its risk oversight function and has delegated to the Audit Committee direct oversight of cybersecurity and information technology risks, including oversight of our cybersecurity risk management and business continuity programs. The Audit Committee reports to the Board at each regular meeting on matters within its oversight. We maintain a comprehensive cybersecurity program designed to (i) protect against threats to the security, confidentiality, integrity and availability of our information and information technology systems, (ii) protect against unauthorized access or use of our systems that could result in substantial harm to us, our employees or our customers, and (iii) identify, detect, contain, respond and recover from cybersecurity incidents.

Our Vice President of Internal Audit and our Chief Information Officer report to the Audit Committee at each quarterly meeting. Quarterly presentations include the rapidly evolving cybersecurity threat landscape, management's efforts to monitor, detect and prevent cybersecurity threats, reports of cybersecurity incidents including those with little or no impact, our cybersecurity incident response protocols, and the effectiveness of our cybersecurity program. If a cybersecurity incident is deemed to have the potential for material impact on the Company, our Incident Response, Reporting and Management Policy has procedures for escalation to the Audit Committee outside of regularly scheduled meetings and to the full Board, if and as appropriate.

Our cybersecurity risk management program includes:

• Risk assessments designed to identify material cybersecurity risks to our information technology systems

• A security team responsible for managing our cybersecurity processes, procedures, controls and incident response

• The use of external service providers where appropriate to assess, test or assist with our security controls

• Security tools for protection against and monitoring for suspicious activity

• Cybersecurity awareness training for employees

• An incident response plan for responding to cybersecurity incidents

• Third-party risk management procedures for service providers, suppliers and vendors

For more detailed information on our cybersecurity program, please refer to our Annual Report on Form 10-K for the year ended December 31, 2025.

Mr. Hilsheimer, chair of our Audit Committee, has earned a CERT Certificate in Cybersecurity Oversight from the National Association of Corporate Directors, which aids the Audit Committee's understanding of the cybersecurity threat landscape and assists the Audit Committee in overseeing an effective cybersecurity risk management program.

As described in more detail in *"Board Committee Oversight"* below, each Board committee receives quarterly reports on the areas within its oversight function and reports on each of these areas to the Board at each quarterly Board meeting. The Board also directly receives periodic sustainability, cybersecurity, and corporate giving reports from Company team leaders at its regular meetings. See also *"Corporate Responsibility"* below.

Each committee is chaired by an independent director, who determines the agenda, frequency and length of meetings and who has unlimited access to management and Company employees. Each committee operates under a written charter approved by the Board that sets forth its responsibilities, and each committee periodically assesses the adequacy of its charter in light of developing best practices and recommends changes to the Board as necessary.

The Board has delegated certain risk management oversight to its committees in their areas of responsibility. The Board is kept informed of each committee's risk oversight activities through reports to the Board presented at every regular Board meeting. The oversight functions of the Board committees described below do not represent a complete list of all enterprise risks and Company practices that are considered and addressed from time to time by the Board committees.

**Director Independence** 

Based upon information provided by each director concerning his or her employment and other affiliations, our NCG Committee and Board of Directors have determined that Mses. Carter, Jackson and Moore and Messrs. Hilsheimer, Meuse, Schottenstein and Thomas have no material relationship with the Company or its subsidiaries, either directly or indirectly, that would interfere with the exercise of their independent judgment, and that each qualifies as an "independent director" as defined by SEC and NYSE rules.

When determining whether a director qualifies as independent, the Board broadly considers all relevant facts and circumstances to determine whether the director has any material relationship with the Company, either directly or indirectly, that would interfere with the exercise of independent judgment. In the course of determining the independence of Mr. Meuse, the Board considered that Mr. Meuse's son is an employee of Blackrock, Inc., which holds more than 10% of our common stock. Based on the fact that Mr. Meuse's son is not an executive officer, director or control person of Blackrock, Inc., the Board does not believe that this relationship impairs the independence of Mr. Meuse. In the course of determining the independence of Mr. Schottenstein, the Board considered that Mr. Schottenstein is the Chief Executive Officer of M/I Homes, Inc., a national single-family homebuilding company with which we conduct transactions in the ordinary course of our business. Based on the aggregate annual value of these transactions (less than 1% of the annual revenues of each of the Company and M/I Homes, Inc. in 2025) and the nature of the transactions (which is the sale and installation of building products in new residential homes in the ordinary course of business of both companies), the Board does not believe that this relationship impairs the independence of Mr. Schottenstein or that Mr. Schottenstein has any material interest in any transaction between the Company and M/I Homes, Inc. Upon careful consideration, the Board of Directors has determined that seven of our nine directors are independent, and that each Board committee is comprised entirely of independent directors. There are no family relationships among our executive officers and our directors.

In making its independence recommendations, the NCG Committee evaluates the commercial, charitable and employment relationships that exist between the Company and the directors and entities with which they or members of their immediate families are affiliated (including charitable institutions to which we have given donations if the director is affiliated with such institutions). The NCG Committee also considers other relevant facts and circumstances regarding the nature of these transactions and relationships to determine whether other factors, regardless of the independence standards, might compromise a director's independence.

**Annual Board and Committee Self-Assessments** 

Pursuant to NYSE requirements, our Corporate Governance Guidelines and the charters of each of our Board committees, the Board and each of its committees conduct an annual self-assessment. The self-assessment is intended to determine whether the Board and the committees are functioning effectively and to provide them with an opportunity to improve. The self-assessment enables directors to provide confidential feedback on topics including the effectiveness of Board oversight of management, business strategy and enterprise risk; Board and committee composition, structure, skills and function; Board and management culture; Board resources and processes; and the effectiveness of individual directors. A summary of the results is presented to the NCG Committee, which is responsible for oversight of the process. The NCG Committee reports the results of the self-assessments to the Board, which considers ways in which Board and committee effectiveness may be improved. This process helps identify opportunities to consider implementing new practices and procedures as appropriate. While the formal self-evaluation is conducted on an annual basis, the directors share perspectives, feedback and suggestions throughout the year.

**Meetings of the Board and Director Attendance** 

The Board of Directors held eight meetings during 2025. Each director attended, in person or by conferencing video or telephone, at least 75% of the total number of meetings of both the Board and the committees on which he or she served during the year. Board members frequently attend meetings of committees on which they are not members to gain a better perspective of issues outside the purview of their committees. Board agendas are set in

advance by management with the assistance of the Presiding Independent Director and the committee chairs to ensure that appropriate subjects are covered. Any member of the Board may request that an item be included on the agenda and often make such requests. Directors are provided with materials in advance of meetings and are expected to review these materials before each meeting to ensure that time in Board and committee meetings is focused on active discussions versus lengthy presentations. Although we do not have a formal policy requiring Board members to attend annual meetings of our stockholders, our directors are expected to make every effort to attend. All of our directors attended the Annual Meeting of Stockholders in 2025.

**Executive Sessions of the Board** 

The Board holds regularly scheduled executive sessions in which the independent directors meet without the presence of management. These meetings allow the independent directors to discuss the business and affairs of the Company, the Company's operating and financial performance and stockholder return, as well as matters concerning the performance of senior management, without any member of management present. Ms. Carter, as the Presiding Independent Director, chairs the meetings and acts as liaison among the independent directors and the other Board members and management. As part of the executive sessions, the independent directors may meet with our Chief Executive Officer, our management team members and representatives of our independent registered public accounting firm as they deem necessary or appropriate. The independent directors held four meetings in executive session during 2025, and the Audit Committee held four meetings in executive session in 2025.

**Code of Business Conduct and Ethics** 

The Board has adopted an Ethics Code to promote honest and ethical conduct by our directors, officers and employees. Each director, officer and employee must observe the highest ethical standards of business conduct in dealings with our customers, suppliers, partners, service providers, competitors and employees. Directors, officers and employees may not give or receive any gift unless it meets certain requirements, including that the gift is not cash or a cash equivalent, comports with customary local business practices and is not excessive in value.

The Ethics Code governs conflicts of interest, including financial involvement with, or ownership of, an entity that has business relationships with the Company. A director may serve as a board member of a customer or supplier of the Company only if such service would not affect his or her status as an independent director. The Ethics Code prohibits loans by the Company to, or guarantees by the Company of obligations of, any director or officer or their family members. Directors and executive officers must seek prior review and approval of potential conflicts of interest from the Audit Committee.

All directors, officers and employees are prohibited under the Ethics Code from using Company assets, information or position for personal gain. Unauthorized use or distribution of the Company's proprietary information such as trade secrets, patents, trademarks and copyrights, as well as business and marketing plans, business processes, designs, databases, proprietary software, customer information, records and any non-public financial data or reports is prohibited.

Suspected violations of the Ethics Code involving directors or executive officers must be reported to the Audit Committee, or the General Counsel for other employees. Upon investigation and a determination that there has been a violation of the Ethics Code, the Board or General Counsel will take such preventative or disciplinary action deemed appropriate, including reassignment, demotion, dismissal and, in the event of criminal conduct or other serious violations of law, notice to appropriate governmental authorities. We do not tolerate acts of retaliation against anyone who makes a good faith report of known or suspected acts of misconduct or other violations of the Ethics Code.

| **Short Sales** | &nbsp;&nbsp;Directly or indirectly selling any equity security of the Company if the person does not own the security, including a "sale against the box" (a sale with delayed delivery). |
| **Hedging** | &nbsp;&nbsp;Engaging in, directly or through family members or other persons or entities, any hedging or monetization transactions involving Company securities, including through the use of financial instruments such as puts, calls, publicly-traded options, swaps, forwards, warrants and any other derivative or similar instruments. The Board has made an exception for our CEO in connection with financing arrangements made by a family-owned investment vehicle. For additional details, see Footnote 3 in the "Stock Ownership Table" beginning on page [89](#i4430d499364a412791c1ca0d068409f9_334). |

The policy also prohibits our directors, officers and certain other designated employees from engaging in the following transactions in Company stock:

---

| | |
|:---|:---|
| **Pledges and**<br>**Margin Accounts** | &nbsp;&nbsp;Pledging Company securities as collateral for a loan or holding Company securities as collateral in a margin account. Any person who engages in a hedging transaction involving Company securities, pledges Company securities as collateral for a loan or holds Company securities as collateral in a margin account is not eligible for election or re-election as a director. The Board has made an exception for our CEO in connection with financing arrangements made by a family-owned investment vehicle and for a Director in connection with a pledge of Company stock to secure a loan. For additional details, see Footnotes 3 and 9 in the "Stock Ownership Table" beginning on page [89](#i4430d499364a412791c1ca0d068409f9_334). |

---

Our Insider Trading Policy has procedures that require transactions in our stock by executive officers, directors and other designated employees, and each of their family members and members of their households, only be made during open trading windows after satisfying mandatory pre-clearance requirements.

In addition to the foregoing policy provisions applicable to our executive officers, directors and other designated employees, our Insider Trading Policy governs the processes by which the Company repurchases its securities. We believe that our insider trading policies and repurchase procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations and NYSE listing standards. The foregoing summary of our Insider Trading Policy is not complete and is qualified by reference to the full text of our Insider Trading policy, a copy of which is included as Exhibit 19 to our Annual Report on Form 10-K for the 2025 fiscal year.

**Stockholder Engagement** 

Developing and fostering long term relationships with our stockholders is a key priority. We actively engage with our stockholders regarding our business strategy, operations, industry trends and conditions, growth opportunities, financial performance, climate and environment issues, workplace culture and other issues. Throughout the year, members of our Investor Relations team and management seek input and feedback through telephone and video calls and in-person meetings with our stockholders to stay informed on their perspectives and to increase their understanding of our business and industry. In 2025, we engaged with over 600 investment professionals representing approximately 220 investment firms, with more than one engagement throughout the year with many of those individuals. Feedback received from our stockholder engagement activities informs our decision-making on our business strategy, capital allocation, corporate responsibility, executive compensation, and ESG initiatives. Recent stockholder engagement topics have included U.S. consumer confidence, housing affordability, residential end market demand; core business operations, including material availability, material cost and installed service pricing trends; economic policy changes including U.S. fiscal, monetary, trade and immigration policies; and supporting our employees and our communities through our Foundation and charitable giving. In February 2025, we adopted the Five Year Performance Share Award Plan to better align our executive compensation program with our peers and based on management's discussions with investors. See *Compensation Discussion and Analysis – "Section 3 – Elements of our Compensation Program – Five Year Performance Share Award Plan*."

During 2025, senior executives participated in 10 conferences and three non-deal roadshows. We engaged with approximately 47% of institutional stockholders who held at least 1% of our shares, including 44% of our top 10 institutional stockholders based on percentage of ownership of our common stock.

**Communication with Directors** 

Stockholders and other interested parties wishing to communicate with the Board of Directors or to any particular director, including the Presiding Independent Director, may do so by writing to the following address: c/o Corporate Secretary, Installed Building Products, Inc., 495 South High Street, Suite 50, Columbus, Ohio 43215. The Board has directed the Corporate Secretary's office to forward to the appropriate director(s) all correspondence, except for items unrelated to the functions of the Board, business solicitations and advertisements.

**Stockholder Nominations of Director Candidates** 

In identifying potential candidates for Board membership, the NCG Committee may rely on recommendations from directors, stockholders, management and others. The NCG Committee reviews all candidates in the same manner, regardless of the source of the recommendation. Stockholders who wish to recommend or nominate a director candidate must comply with certain procedures. If you desire to nominate a director candidate for the 2027 Annual Meeting of Stockholders, you must comply with the procedures for nomination set forth in *"Stockholder Proposals for the 2027 Annual Meeting."* Stockholders may recommend a director candidate for consideration at any time by giving written notice to our Corporate Secretary at Installed Building Products, Inc., 495 South High Street, Suite 50, Columbus, Ohio 43215. The recommendation must include the candidate's name, age, business address, residence address and principal occupation or employment, as well as a description of the candidate's qualifications, attributes and other skills. The NCG Committee may require additional information before considering the candidate. These procedural requirements are intended to ensure that the NCG Committee has sufficient time and a basis upon which to assess potential director candidates and are not intended to discourage or interfere with stockholder nominations.

**Corporate Responsibility**

We recognize the importance of environmental and social issues and their impact on our stockholders, our customers, our employees and our communities. Good corporate citizenship is important to us and we are committed to investing in the communities where we live and work. We integrate corporate responsibility every day through making buildings energy efficient, providing for the health, safety and welfare of our employees, advocating volunteerism and committing to philanthropy.

In 2022, we named Jason R. Niswonger, one of our executive officers, as our Chief Administrative and Sustainability Officer. Mr. Niswonger is responsible for leading and coordinating our ESG initiatives. We released our annual Sustainability Report in October 2025, which can be found on our website at https://installedbuildingproducts.com/sustainability/.

The NCG Committee is responsible for the oversight of our ESG programs, except to the extent reserved to the full Board or another Board committee, and directly oversees our sustainability programs. The CHC Committee oversees our human capital management policies and practices, including inclusion and belonging, talent development initiatives, employee recruitment and retention and employee compensation practices, and oversees our Foundation and corporate giving activities. The Board and its committees receive periodic reports on sustainability, employee programs and initiatives and Foundation initiatives from Company team leaders at regular meetings.

We strive to make a positive impact on our environment, our people and our communities. Our efforts are focused on three pillars:

---

| | | |
|:---|:---|:---|
| **Going Beyond the Buildings** | **Committing to Our People** | **Elevating our Neighborhoods** |
| &nbsp;&nbsp;Recognizing the importance of environmental preservation and the direct connection between our business and the health of our planet and the well-being of our communities. | &nbsp;&nbsp;Striving to uplift and empower our employees to help them thrive both professionally and personally. | &nbsp;&nbsp;Giving back and contributing to the strength and vitality of the communities where our employees live and work. |

---

**Going Beyond the Buildings** 

We play a direct role in creating a sustainable future through our day-to-day business operations by installing products that promote energy efficiency. According to the Office of Energy Efficiency & Renewable Energy, over $400 billion is spent each year to power homes and commercial buildings that consume 75% of all electricity used in the U.S. and 40% of the nations' total energy. Insulation and air sealing play a critical role in reducing energy consumption. Insulated homes and commercial buildings reduce both energy consumption and greenhouse gas emissions. In addition to the wide range of insulation materials we offer, we also install a variety of advanced caulk and sealant products that control air infiltration to enhance energy efficiency, improve comfort and meet increasingly stringent energy codes.

In addition to the contribution that our insulation and air barrier installations make to energy conservation throughout the United States, we are searching for ways to reduce our own carbon footprint. We have transitioned a substantial portion of our electricity needs to a carbon free source and maintain a national waste management program to increase recycling at our branches. More information about insulation and energy efficiency and our environmental targets may be found in our Sustainability Report.

The Home Energy Raters System ("HERS") is the industry standard for measuring a home's energy efficiency. We employ several accredited HERS raters and have affiliations with others. HERS raters review insulation levels, window efficiency, HVAC system efficiency and water heating systems. They also do performance testing such as blower door tests to examine air and duct leakage.

| **Fiberglass Insulation Installation Services.** The most common type of insulation we install is fiberglass, which is comprised of 50-80% recycled material. Our insulation and air barrier installation services provide the critical link between manufacturer inventory and builders and homeowners who desire to promote energy efficiency or meet increasingly stringent building codes. Our installation professionals receive extensive training, including thermal performance, moisture prevention, air infiltration and ventilation, so that we can employ the latest techniques and technologies to improve energy efficiencies. | ![Image_55.jpg](ibp-20260408_g37.jpg) |
| **Loosefill Insulation Installation Services.** Another type of fiberglass insulation we install is loosefill, or blown-in, insulation. We have a production facility in Shelbyville, Indiana that retrieves manufacturers' waste fiberglass material that would otherwise be sent to a landfill and produces loosefill insulation suitable for blowing into attics. In 2025, we reclaimed 2.8 million pounds of scrap material that would otherwise have been placed in a landfill and insulated over 4.2 million square feet of space (to an R value of R30) using this recycled material. | ![Image_56.jpg](ibp-20260408_g38.jpg) |
| **Cellulose Insulation Manufacturing.** Another product we install is cellulose insulation, which is installed in the walls, ceilings and attics of new homes. In 2025, Advanced Fiber Technology, our manufacturing plant located in Bucyrus, Ohio and Carolina Precision Fibers, our manufacturing plant located in Ronda, North Carolina (which we acquired in September, 2025), produced 93,894 tons of cellulose products consisting of a minimum of 85% post-consumer recycled waste paper and cardboard. The two plants processed approximately 88,744 tons of recycled wastepaper to make our finished cellulose products which might have otherwise decomposed in a landfill, releasing methane and carbon dioxide gases. The manufacturing process does not directly emit atmospheric gases or use water. In 2021, the Bucyrus plant transitioned its electricity supply, which comprised approximately 38% of our total electricity consumption in 2024, to a carbon-free source. In 2024, the Bucyrus plant began recycling polypropylene supply packaging and scrap bag film, which we estimate will reduce the amount of waste we send to the landfill by at least 70,000 pounds annually. | ![Image_57.jpg](ibp-20260408_g39.jpg) |

**Committing to Our People**

The CHC Committee oversees our human capital management practices and receives regular updates on our employee welfare initiatives and employee engagement. The experience of the CHC Committee members in support of social initiatives and in human capital management strengthens the Board's oversight and assures that our business strategy and long-term value creation are achieved within a responsible business model. Our culture of family unifies our workforce of approximately 10,160 employees in over 250 locations across the United States.

We strive to create an inclusive work culture for people of all backgrounds. We have developed a number of initiatives to help attract, develop and retain our workforce, which reduces turnover and training costs, increases productivity, builds a culture of belonging, enhances employee engagement, promotes a safer work environment, encourages customer loyalty and promotes community engagement. We believe that our retention efforts have reduced turnover levels across our installer base below the industry average, based on statistics reported by the U.S. Bureau of Labor Statistics. For example, in 2025, we experienced an average monthly turnover in our installer base of 3.2%, compared to 4.0% in the U.S. construction industry, according to the Bureau of Labor Statistics.

Our vision is to build an empathetic organization and to foster a culture that values inclusion and employee engagement and to create an environment where all employees feel as though they belong. Our employee initiatives are overseen by the CHC Committee, and include:

• Leadership training and development programs;

• Building an expanded hiring pipeline;

• Conducting employee focus groups to understand employee perceptions;

• Broadcasting our Positive Production Program videos to educate and encourage inclusion and employee well-being; and

• Offering both English and Spanish as a Second Language classes to remove communication hurdles among our workforce.

**Benefits**

Offering competitive pay and benefits helps us attract and retain talented employees. We offer a full range of benefits to qualifying employees, including medical, dental and vision insurance, prescription drug coverage, flexible spending accounts, 401(k) retirement programs with matching contributions, paid vacations and holidays, short- and long-term disability insurance, life insurance and group accident and critical illness insurance.

**Safety**

Employee safety is a core business objective. Our installers engage in physically strenuous, and, at times, hazardous work. We have detailed safety policies and each year significant staffing, funding and resources are allocated to safety and risk management. We have strong workplace safety measures that we call Lead with Safety, a continuing education program focused on creating a safer working environment for our employees and other jobsite personnel through year-round education and training. We have regional safety managers who are OSHA 500 certified outreach trainers who conduct intensive courses on OSHA safety training.

We track all incidents that occur on our job sites that could result in injury, including minor incidents that may not require first aid or medical treatment. We use this information to mitigate the potential for severe accidents and to refine our safety training programs. We believe our safety programs are having a positive impact. Our OSHA-defined incident rate per 100 employees was 5.5 for 2025, which was an increase of 0.4 from 2024, and below our five year average of 5.7. Severe incidents decreased from 11 in 2024 to 10 in 2025. We have had no fatalities in the past three years.

Our safety programs include more than 35 training videos and a comprehensive list of policies and procedures for common construction industry hazards, including confined space, fall protection, hazardous chemicals communication, respiratory protection, hand and portable power tools, and drywall storage safety. Drivers take part in our fleet safety program. Each installer receives initial safety training upon hire and may receive tailored training depending upon duties. Safety training continues with weekly toolbox talks, quarterly safety initiatives, annual refresher training and safety excellence awards, keeping safety at the forefront for every employee.

**Financial Wellness Program**

We offer a multifaceted financial wellness education program to our employees to increase education and encourage responsible personal financial decision-making. The program educates participants on key personal financial topics, including budgeting, credit scores, debt reduction, saving and giving back to the community. One of the key components of this program is encouraging employees to establish personal savings accounts, which the Company matches dollar for dollar up to $1,000. Since inception of the program, we have matched over $6 million in employee personal savings. We believe this valuable program not only helps address employee retention, but helps educate our employees to prepare for their financial security.

**Longevity Awards**

Our longevity award program rewards employees who do not otherwise receive awards under another Company stock program for their long-time dedicated service to the Company. Eligible employees are awarded grants of restricted stock units for each ten years of continuous service to the Company, including service for companies that we acquire. Provided the Company meets a revenue target established in advance by the CHC Committee, employees are awarded restricted stock units based on a percentage of wages that convert one year later into shares of our common stock (for 2025 awards, the target was approximately $2,878.4 million trailing 12-month revenue from July 1, 2024 to June 30, 2025). Through December 31, 2025, we have awarded approximately 177,000 restricted stock units under the program to approximately 2,225 employees with tenures ranging from 10 to 48 years. We believe the program rewards employees for valued service, assists in retention of our highly valued long-term employees and results in a highly motivated and engaged workforce.

**Positive Production Program**

The Positive Production Program is a well-being program developed for our employees to foster positive mental attitudes and to provide personal development learning opportunities. The goals of the program are:

• To provide opportunities to build strong relationships among employees and connect with one another

• To build strong teams and work environments with engaged employees

• To provide opportunities for employees to learn and grow

• To improve employee well-being by building awareness and sharing best practices

The elements of the Positive Production Program include in-house produced videos on topics such as growth mindset, emotional intelligence and gratitude. The program focuses on essential workplace skills such as building trust, accountability, habit formation and goal setting, with the objective of enhancing collaboration, productivity and personal development.

**Proposal 2 – Ratification of the Appointment of Our Independent Registered Public Accounting Firm**

**Overview** 

Our Audit Committee is responsible for the appointment, compensation, retention and oversight of our independent registered public accounting firm. The Audit Committee has appointed, and the Board has ratified the appointment of, Deloitte & Touche LLP ("Deloitte") to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Deloitte has served as our independent registered public accounting firm since 2013.

The Audit Committee annually reviews Deloitte's performance and independence in deciding whether to retain Deloitte or to engage a different independent registered public accounting firm. In evaluating Deloitte's performance, the Audit Committee considers a number of factors, among other things:

• the quality of the historical and recent performance of the firm;

• audit quality and efficiency, including the performance of the audit partner and audit team and their audit approach;

• the quality and candor of the firm's communications with the Audit Committee;

• the independence, objectivity and integrity of the firm;

• known significant legal or regulatory proceedings against the firm;

• the firm's internal quality control procedures;

• the appropriateness of the firm's fees; and

• the benefits of having a long-tenured auditor and potential impact of selecting a new auditing firm.

Based upon its assessment of Deloitte's performance, the Audit Committee believes that the retention of Deloitte as our independent registered public accounting firm is in the best interests of the Company and our stockholders. The Audit Committee believes that Deloitte's tenure as our independent registered public accounting firm confers distinct benefits, including enhanced audit quality and efficiency due to Deloitte's significant institutional knowledge of the Company and its operations, accounting practices and internal controls framework.

We are asking our stockholders to ratify the selection of Deloitte as our independent registered public accounting firm for 2026. Although stockholder ratification is not required, we value our stockholders' views on our independent registered public accounting firm. If our stockholders fail to ratify the appointment of Deloitte, the Audit Committee will reconsider whether or not to retain Deloitte and may retain that firm or another firm without resubmitting the matter to our stockholders. Even if the selection of Deloitte is ratified, the Audit Committee may, in its discretion, select a different firm 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 Deloitte is expected to be present at the Annual Meeting, will be given an opportunity to make a statement and will be available to respond to appropriate questions.

**Fees Paid to Deloitte** 

Deloitte audited our consolidated financial statements and effectiveness of internal controls over financial reporting during the years ended December 31, 2025 and 2024. During these periods, Deloitte provided both audit and non-audit services. The following table sets forth the aggregate fees we paid to Deloitte in 2025 and 2024, respectively.

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| Audit Fees | $2598762 | $2569235 |
| Audit-Related Fees | 60000 | 33442 |
| Tax Fees |  |  |
| All Other Fees | 2047 | 2037 |
| **Total** | **$2660809** | **$2604714** |

---

Audit Fees include fees for professional services rendered in connection with the audit of our annual consolidated financial statements and internal control over financial reporting, review of our quarterly consolidated financial statements and services that are normally provided in connection with statutory and regulatory filings or engagements.

Audit-Related Fees were fees for permissible advisory services in connection with enterprise risk management services.

Tax Fees were fees for professional services rendered in connection with tax consultation services.

All Other Fees were fees for permissible work performed by Deloitte that does not fit within the above categories. The fees under this category are related to technical subscriptions.

**Pre-Approval of Services** 

The Audit Committee has established a policy requiring pre-approval of all audit and non-audit services provided by our independent registered public accounting firm. On an ongoing basis, management submits to the Audit Committee specific projects and services to be performed by Deloitte for which it seeks advance approval. The Audit Committee reviews these requests and determines whether to approve the requested engagement. Periodically management reports to the Audit Committee the actual spending for such projects and services compared to the approved amounts. All services provided by Deloitte in 2025 were pre-approved by the Audit Committee in accordance with this policy.

| **Report of the Audit Committee** |
| Management is responsible for the preparation and presentation of the Company's financial statements and for developing and maintaining internal controls over financial reporting and procedures that are reasonably designed to assure compliance with accounting standards and applicable law. The Company's independent registered public accounting firm, Deloitte & Touche LLP ("Deloitte"), is responsible for performing an independent audit of the Company's consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB").<br>The Audit Committee's responsibility is to provide independent and objective oversight of the Company's financial reporting and internal controls processes and the audit work of Deloitte. In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed with management and Deloitte the Company's audited consolidated financial statements for the fiscal year ended December 31, 2025, the fair and complete presentation of the Company's results and the assessment of the Company's internal controls over financial reporting. The Audit Committee discussed significant accounting policies applied in the Company's financial statements, and, when applicable, alternative accounting treatments. Management represented to the Audit Committee that the financial statements were prepared in accordance with accounting principles generally accepted in the United States. The Audit Committee has also discussed with Deloitte the matters required by the applicable requirements of the PCAOB and the Securities and Exchange Commission.<br>In addition, the Audit Committee reviewed and discussed with Deloitte its independence from the Company and management. As part of that review, the Audit Committee received the written disclosures from Deloitte required by the PCAOB, and the Audit Committee considered and discussed Deloitte's independence, including whether the firm's provision of non-audit services to the Company is compatible with its independence. The Audit Committee concluded that Deloitte is independent from the Company and its management.<br>The Audit Committee discussed with the Company's Internal Audit department and Deloitte the overall scope of and plans for their respective audits. The Audit Committee meets with the Vice President of Internal Audit and representatives of Deloitte, in regular and executive sessions, to discuss the results of their examinations, the evaluations of the Company's internal controls and the overall quality of the Company's financial reporting and compliance programs.<br>Based on these reviews and discussions, the Audit Committee has recommended to the Board that the audited consolidated financial statements for 2025 be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The Audit Committee has selected, and the Board of Directors has ratified the selection of, Deloitte as the Company's independent registered public accounting firm for 2026.<br>**Audit Committee**<br>• Lawrence A.

**Proposal 3 – Non-Binding Advisory Vote on Executive Compensation**

As required by Section 14A of the Securities Exchange Act of 1934 (the "Exchange Act") and as a matter of good corporate governance, we are seeking stockholder approval of our executive compensation program. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers ("NEOs") and the executive compensation program and practices described in this Proxy Statement.

Stockholders are being asked to vote on the following advisory resolution:

*"RESOLVED, that the Company's stockholders approve, on an advisory basis, the compensation of the Company's named executive officers for 2025, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis and accompanying compensation tables and related narrative disclosures in the Company's Proxy Statement."* 

We have a pay for performance philosophy that forms the foundation of our decisions regarding payment of executive compensation. We believe that this philosophy and the compensation structure established by the CHC Committee are central to our ability to attract, retain and motivate individuals who can achieve superior financial results in the best interests of the Company and our stockholders. We link pay to performance by weighting a significant portion of the target compensation of our NEOs in variable, or "at risk," compensation elements. We also align our NEOs' financial interests with those of our stockholders by awarding a substantial portion of total compensation in the form of equity that is coupled with stock ownership requirements.

We urge you to read "Executive Compensation – Compensation Discussion and Analysis" below, which describes in detail how our executive compensation program operates and is designed to achieve our compensation objectives, as well as the accompanying compensation tables and narratives that provide detailed information on the compensation of our NEOs.

This advisory vote, commonly referred to as a "say-on-pay" advisory vote, is non-binding. However, the outcome of the vote will provide valuable information to the CHC Committee regarding stockholder sentiment about our compensation program, which the CHC Committee will consider when making future decisions regarding the compensation of our NEOs. Our executive compensation program was strongly supported by our stockholders in 2025, with approximately 97% of the votes cast at the 2025 Annual Meeting of Stockholders voting in favor. We have held a similar stockholder vote every year since 2017 and expect to hold a similar vote at the 2027 Annual Meeting of Stockholders.

**Section 1 – Executive Summary** 

**Growth Strategy**

We are focused on diversifying our products and services, broadening our mix of end market exposure and expanding our geographic footprint. Our growth strategy includes acquisition of residential and commercial installers in new markets, acquisitions of businesses offering complementary products, introduction of new product offerings in existing markets, pursuit of new product categories in commercial markets, and expanding our multi-family sales in existing branches.

We have a demonstrated record of success for each of our growth strategies:

**• Product diversification** - Revenue from insulation installation services represented approximately 79% of our total revenues in 2015 compared to 58% in 2025.

**• End market diversification** - We have decreased our single family residential new construction end market exposure from 75% in 2015 to 55% in 2025.

**• Geographic expansion** - We have added approximately 150 branch locations since 2014.

**Capital Allocation Strategy**

Our capital allocation priorities include:

• Acquisitions, which contribute to our profitability and anchor our growth strategies of product, end market and geographic diversification, and

• Quarterly and annual variable dividends and opportunistic share repurchases, which provide direct returns to our stockholders.

• In 2025, we acquired eleven businesses with revenues of approximately $64 million, which expanded our geographic presence in attractive housing markets. We returned $261 million to stockholders, including quarterly and variable dividends of $88 million and stock repurchases of $173 million.

**Acquisition Strategy**

In the 1990s, we began our acquisition strategy with the goal of creating a national platform and have since grown, by our estimate, to become one of the nation's largest installers of insulation in the residential new construction end market. Since 1999, we have successfully completed and integrated over 200 acquisitions, which have expanded our scale and market presence and diversified our product offerings and end market exposures. Our asset-light model generates substantial operating cash flow, which supports further acquisition growth. In 2025, we successfully acquired and integrated eleven businesses representing approximately $64 million in aggregate annual revenues.

1. In Q2 2022, we changed the criteria for how acquisitions are counted in the chart. Generally, acquisitions presented meet the following criteria: (1) we pay for goodwill; (2) business has a standalone location; (3) business name is projected to remain over the long term; and (4) purchase price greater than $0.5 million. The first acquisition that meets this criteria was completed in 1994. U.S. residential completions data based on U.S. Census Bureau in million units, left axis.

1.\*See *"Additional Information – Use of Non-GAAP Financial Measures"* for a reconciliation of Adjusted EBITDA to the most directly comparable U.S. generally accepted accounting principles ("GAAP") measure. Figures above reflect year over year increases.

**Pay for Performance**

Our executive compensation philosophy is to provide a competitive compensation package weighted toward Company performance and aligned with our stockholders' long-term interests. The CHC Committee believes that our executive compensation program drives performance and increases stockholder value. The CHC Committee believes that total compensation for the Company's named executive officers should align with the Company's financial and strategic objectives and sustained growth, as well as individual performance, level of responsibility and experience. Consistent with that philosophy, in 2025 approximately 86.5% of our Chief Executive Officer's and an average of 75.4% of our other named executive officers' total target compensation reflected our continued emphasis on at-risk compensation linked with the Company's operational and financial performance. Any incentive compensation earned by our NEOs depends upon the Company's achieved Adjusted EBITDA and adjusted general and administrative expense as a percentage of revenue during the performance period as compared against the targets set in advance by the CHC Committee. For annual share awards other than shares awarded under the Five Year Plan, performance-based restricted stock is awarded as a number of shares rather than a fixed dollar amount, so the value of the restricted stock award fluctuates with our stock price during the performance period and the additional two year vesting period, strongly aligning the interests of our NEOs with the interests of our stockholders.

**2025 Say-on-Pay Voting Results**

Our executive compensation program received strong support from our stockholders in 2025, with more than 97% the votes cast at the 2025 Annual Meeting of Stockholders voting in favor. The CHC Committee believes that this level of support is indicative of our stockholders' strong support of our compensation practices and pay for performance alignment and influenced its decision to retain the core elements of our executive compensation program.

2. The value listed in this column includes both annual performance-based restricted stock awards and performance-based shares awarded under Component 2 of the Five Year Plan. The earned fair value was determined by multiplying the closing price of the Company's common stock on February 24, 2026 ($319.99) (the date of certification of the achievement of the performance metric) by the number of shares awarded. The restricted stock vests in equal installments over two years, except for stock awarded under the Five Year Plan, which vests on April 20, 2030, in each case, subject to continued employment.

**2025 Target Compensation Mix** 

Our executive compensation program for 2025 consisted of three components: base salary, performance-based cash awards and performance-based restricted stock awards. Performance-based restricted stock awards include both our annual compensation program and the annual component of our Five Year Plan. The CHC Committee believes that a significant portion of each NEO's target compensation should be at risk and based on Company performance. The graphics below reflect the mix of target executive compensation for 2025 and highlights the at-risk portion of total target compensation:

**Section 2 – How We Determine Pay**

**Our Philosophy**

Our executive compensation philosophy is to provide a competitive compensation package weighted toward Company performance and aligned with our stockholders' long-term interests. Our executive compensation program is both reflective of the strategic value of the individual's position and designed to ensure long-term retention and motivation. Our objective is to offer compensation opportunities competitive with our peer companies with respect to overall compensation (cash and equity), allowing for differences in the Company's size, scale and scope and the individual's job responsibilities.

**Our Goals**

• To attract, motivate and retain exceptional executives who are critical to successful execution of the Company's growth strategy, long-term Company performance and the creation of stockholder value.

• To align the interests of our executives with those of our stockholders by tying a significant amount of executive compensation to the achievement of performance metrics related to our business strategy and financial performance and to the price of our stock.

• To motivate our executives to perform at the highest level, to achieve our financial, operational and strategic goals and to reinforce our commitment to high-quality service, which is primarily responsible for the strength of our long-standing relationships with our customers and suppliers.

**Our Guiding Principles**

**• Pay for Performance.** We reward our executives' achievements by linking a significant portion of their compensation to the Company's financial and operational performance. Our incentive compensation program has pre-established objective performance metrics that reflect strategic and operational objectives. Incentive compensation varies based on the extent to which an objective is met.

**• Competitive Pay.** Our compensation program is designed to attract, retain, motivate and reward top talent through pay elements that are flexible and competitive with our peers.

**• Internal Pay Equity.** We believe that internal pay equity ensures fairness and encourages a collaborative environment among our executive team. The CHC Committee reviews each NEO's pay components and levels relative to other NEOs, considering experience, leadership role, seniority and level of responsibility.

**• Aligned with Stockholders.** A significant portion of our executives' compensation is in the form of at-risk performance-based equity awards that, if earned, vest over an additional two years after the end of the performance period, or, under the Five Year Plan, after five years. Under our annual stock award plan, we award restricted stock based on a number of shares, rather than a dollar value, so the value of an executive's equity-based award fluctuates with the price of our common stock during the performance period and the vesting period, which aligns the long-term interests of our executives with those of our stockholders. In furtherance of this principle, our NEOs are required to maintain levels of ownership of our common stock based upon a multiple of their salaries.

The CHC Committee considers the overall mix of cash and equity compensation, annual and long-term incentives and fixed and variable pay in determining our executive compensation program. The CHC Committee does not follow any pre-established policies, guidelines or formulas for allocating compensation mix, instead retaining flexibility by determining annually what it believes is the appropriate mix of compensation elements.

**Our Process**

**Role of the CHC Committee.** Our CHC Committee, comprised solely of independent directors, is responsible for the establishment, implementation, administration and oversight of our executive compensation program. During its regular first quarter meeting, the CHC Committee, in consultation with our Chief Executive Officer and Chief Financial Officer, determines incentive compensation earned by our NEOs based on the prior year's performance and finalizes base salary, performance metrics and target incentive compensation levels for the current year. Later in the year, the committee reviews materials relating to peer group composition and other information that forms the basis for future decisions. The CHC Committee sets compensation consistent with our compensation philosophy and competitive with our peers, considering a balance of information including the experience, leadership, level of responsibility and performance of the executive team. While the CHC Committee consults with management and its independent compensation consultant in determining our compensation program, final authority rests solely with the committee. For more information regarding the CHC Committee, see *Corporate Governance – "Board Committee Oversight – Compensation and Human Capital Committee."* 

**Role of Executives.** In the course of determining executive compensation, the CHC Committee solicits input from management. The committee believes this input is valuable because of the Chief Executive Officer's and Chief Financial Officer's comprehensive knowledge of our business and financial and strategic goals. Our Chief Executive Officer and Chief Financial Officer (i) provide data, analysis and recommendations to the CHC Committee regarding the Company's compensation programs, (ii) annually evaluate the performance of our NEOs (other than themselves) based on each individual's performance, length of service, experience, level of responsibility and achievement of Company strategic goals, and (iii) propose to the committee the performance metrics for target incentive awards. The CHC Committee from time to time delegates certain administrative duties to management and the human resources department.

**Role of Compensation Consultants.** The CHC Committee engages Meridian Compensation Partners, LLC, ("Meridian"), as an independent consultant to assist the committee with its duties. Meridian reports directly to the committee. In 2025, the CHC Committee engaged Meridian to perform a review of our executive compensation program and non-employee director compensation and to conduct market comparisons with our peer group. The committee considered Meridian's advice in structuring our compensation program. The CHC Committee intends to engage Meridian or a similar firm to review our executive compensation and non-employee director compensation programs approximately every two years, unless the committee determines to have a more frequent review. In connection with the engagement of Meridian, the committee considered and assessed all relevant factors, including those set forth in applicable SEC and NYSE rules, that could give rise to a potential conflict of interest. Based upon this review, the CHC Committee determined that engaging Meridian did not raise any conflict of interest.

**Competitive Positioning**

Meridian, in consultation with our management and CHC Committee, compiles reports of compensation data for executive officers and non-employee directors in our peer group. The data for executives includes base salary, target cash incentive compensation, long-term incentive awards, target total compensation and variable pay mix. Meridian compiles this data from the proxy disclosures of the peer group and from published surveys. Using the information provided by Meridian, the CHC Committee gauges the reasonableness and competitiveness of our executive compensation program. While the CHC Committee does not establish executive pay based solely on peer group data, it believes that our pay levels and practices should be within a range of competitiveness.

The CHC Committee reviews Meridian's report summarizing the target total cash compensation (base salary plus target annual incentive) and target total compensation (base salary plus target annual incentive plus long-term incentive) for each of our NEOs against benchmarks at the 25th, median and 75th percentiles of the market for positions comparable to those held by each of our NEOs. For retention, motivation and competitive considerations, the CHC Committee targets each NEO's total cash compensation and total direct compensation levels at approximately the median of the peer group.

To determine our peer group, Meridian recommended that the CHC Committee consider a number of factors for each potential peer company, including industry classification and business-specific characteristics (scope and products and services), size (revenue and market capitalization) and frequency of inclusion in the peer groups of other peers of the Company. The committee believes our selected peer group includes an appropriate representation of industry competitors and companies with which we compete for executive talent.

For 2025, the CHC Committee selected the following 13 companies as our peer group. Peers are periodically added or eliminated due to acquisition or size changes to maintain a balance of appropriate size, market cap, revenue, similar industry and presence as a competitor for executive talent.

**Advisory Stockholder Vote**

Our executive compensation program received substantial stockholder support at the 2025 Annual Meeting of Stockholders, with more than 97% of the votes cast by our stockholders voting in favor. The CHC Committee believes that this level of support is indicative of our stockholders' strong support of our executive compensation philosophy and goals. Say-on-pay votes provide valuable information regarding stockholder sentiment about our compensation program, which the CHC Committee considers when making future decisions. In accordance with the preference expressed by our stockholders in our most recent say-on-frequency vote in 2023 and as a matter of good corporate governance, our Board has committed to having an annual say-on-pay vote.

**Risk Management**

The CHC Committee regularly undertakes a risk assessment of our compensation programs with the aid of a risk analysis performed by Meridian, to determine whether our programs are appropriately designed to mitigate incentive for short-term risk-taking by executives that could be detrimental to the long-term best interests of the Company and its stockholders. The CHC Committee believes that any risks arising from our compensation programs are not reasonably likely to have a material adverse effect on the Company. The CHC Committee believes that the following features of our executive compensation program appropriately mitigate potential risks:

**• Performance Metrics.** The CHC Committee sets pre-established performance metrics designed to reward success without encouraging excessive risk taking by executives.

**• Equity Vesting.** Our executives are awarded performance-based restricted stock that, if earned, vests over two years of continued service, or if under the Five Year Plan, after five years, rewarding stability and sustained performance.

**• Equity Retention.** Our stock ownership policy requires our executives to own prescribed levels of Company common stock, linking their interests with those of our stockholders.

**• No Hedging or Pledging.** Our executives are prohibited from engaging in hedging or other monetization transactions involving Company securities, pledging Company securities as collateral and holding Company securities as collateral in a margin account (the Board has made an exception for our CEO in connection with financing arrangements made by a family owned investment vehicle and for a Director in connection with securing a loan, see Footnotes 3 and 9 in the "Stock Ownership Table" beginning on page [89](#i4430d499364a412791c1ca0d068409f9_334)).

**• Clawback Policies.** The CHC Committee will recoup excess incentive compensation paid to an executive in the event of a restatement of our financial statements, and may recoup such compensation if an executive has engaged in grossly negligent or intentional misconduct that is a significant contributing factor to an accounting restatement, a significant increase in the value of such executive's incentive compensation or substantial financial or reputational harm to the Company.

**• Other Factors.** Other mitigating factors include benchmarking practices, oversight by a committee of independent directors and a mix of fixed and variable incentive compensation.

**Section 3 – Elements of our Compensation Program**

**Compensation Components**

Our executive compensation program is designed to be simple, competitive and link pay to performance. We design our executive compensation program to reward financial and operational performance and to promote effective strategic leadership. Our approach to executive compensation for the 2025 fiscal year was substantially the same as the approach approved by our stockholders at the 2025 Annual Meeting of Stockholders, with the addition of the Five Year Plan.

Our executive compensation program includes the following three key elements:

---

Our executive compensation program includes both fixed components (base salary and benefits) and variable components (short- and long-term incentive awards) that are directly tied to our financial and operational performance. The CHC Committee annually considers the mix of compensation and may make adjustments after giving consideration to evolving circumstances, the individuals involved and their responsibilities and performance. The CHC Committee believes this mix of components is appropriate because it incentivizes our NEOs to focus on both short- and long-term success, aligns their interests with those of our stockholders and is consistent with peer group practices. The CHC Committee strives to achieve an appropriate balance among the elements of our compensation program but does not apply any set formula in allocating the components. We do not provide perquisites or other special benefits to our executive officers that are not generally available to our salaried employees, other than auto leases or allowances (including insurance) and cell phones. We provide no pension plans or other retirement benefits to our executive officers other than our 401(k) plan, which is available to all of our eligible employees, and our non-qualified deferred compensation plan, which allows our executive officers and other highly compensated employees to defer a portion of their eligible compensation above 401(k) plan limits.

---

**Base Salary**

We provide base salaries to our NEOs to compensate them for performing day-to-day responsibilities and to provide competitive fixed pay to balance at-risk compensation. Base salary is intended to provide a fundamental level of compensation so that our executives do not feel pressured to take unnecessary or excessive risks or to focus on the price of our common stock. The CHC Committee reviews base salaries annually, in the first quarter of each year, and takes into consideration comparative peer group data, the scope of the executive's responsibilities, skills, tenure, experience, individual contribution, retention objectives, internal pay equity and overall mix and amount of compensation elements. Salary adjustments, if any, typically become effective on April 1 of each year. Our Chief Executive Officer's employment agreement provides for a minimum annual base salary of $600,000 but does not provide for guaranteed salary increases. See *"Employment Agreement with Jeffrey W. Edwards"* below for more information.

**Performance-Based Cash Incentives**

We provide our NEOs with annual performance-based cash incentive opportunities, which are designed to reward achievement of short-term performance goals. Incentive award opportunities are tied to the achievement of an objective pre-determined performance metric that is directly related to our financial performance for the year. In February of each year, the CHC Committee, after considering the recommendations of management, sets an annual financial performance target for the year based primarily on the Board-approved budget for the year and establishes for each NEO a target cash bonus expressed as a fixed dollar amount. The cash bonus earned may be above or below target, based on the degree to which the performance metric is met. If the performance metric is achieved at a minimum of 50%, at least some portion of the cash award is earned. Awards are capped at 200% of target. The executive generally must remain employed through the end of the performance period to be eligible for any cash bonus.

In setting performance goals each year, the CHC Committee uses a one-year performance metric so that performance targets reflect current industry conditions, upon which the Company is heavily dependent. This approach takes into account that the Company operates in the residential and commercial construction industry, which is cyclical, seasonal and highly sensitive to macroeconomic and housing market factors over which our executives have no control, including interest rates; inflation; employment levels; housing demand; affordability; material prices; availability and pricing of mortgage financing; financial, political system and credit market stability; consumer confidence and other general economic conditions.

The CHC Committee currently uses Adjusted EBITDA as our performance metric because the committee believes that it serves as the best measure of the success of our growth strategies, provides an effective incentive to maximize operating profitability and aligns management awards with the financial interests of our stockholders. The CHC Committee believes Adjusted EBITDA is the most useful measure of profitability and operating performance as it measures changes in pricing decisions, cost controls and other factors that impact operating performance and removes the effect of our capital structure, asset base, items outside our control and volatility related to the timing and extent of activities such as asset impairments and non-core income and expenses. The annual performance target set by the CHC Committee is based on the budget approved by the Board and the annual and long-term business plan established at the beginning of each fiscal year and is intended to be challenging but fair. The budget and business plan are based upon certain assumptions and estimates of the housing and commercial markets, Company growth objectives and macroeconomic conditions. The performance target established by the CHC Committee in the first quarter is periodically adjusted throughout the year to account for the impact of completed acquisitions. The CHC Committee expects to continue to re-assess the performance metric selection and goal setting processes annually. See *"Additional Information – Use of Non-GAAP Financial Measures"* for a reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure.

**Performance-Based Equity Incentives**

A substantial component of our executive compensation program consists of rewards for long-term growth and enhancement of stockholder value through the use of performance-based incentive equity awards. The award represents an opportunity, with the ultimate realized value of the award determined by our stock performance over the long term. The CHC Committee believes that long-term incentive compensation is an effective way to retain a strong executive team and provide them with incentives to focus on the Company's long-term success.

Except for awards under the Five Year Plan described below, which have different performance metrics and vesting periods, the CHC Committee grants target incentive awards of restricted stock to our NEOs that are performance-based over a one year performance period and which, if earned, vest over two years of continued service after the performance goal is met. The CHC Committee has determined to use a one-year performance metric of Adjusted EBITDA for the reasons outlined in *"Performance-Based Cash Incentives"* above. In order to achieve a balance between the advisability of setting an annual performance metric and our desire to align the interests of our NEOs with the long-term interests of our stockholders, the CHC Committee added the time-vesting component to the performance-based awards. Performance-based restricted stock target awards are based on a fixed number of shares, rather than a dollar amount, so that the value of the executive's award fluctuates with the price of our common stock during the performance period, the vesting period and thereafter. Performance-based restricted stock awards actually earned may be above or below the target award, based on the degree to which the performance metric is met. If the performance metric is achieved at a minimum of 50%, at least a portion of the restricted stock is earned and vests in equal installments over the next two years, generally subject to the NEO's continued employment on the applicable vesting date. Awards are capped at 200% of target.

The CHC Committee believes that the additional two-year vesting period serves as a valuable retention incentive for our NEOs, whose skills and experience are sought after within the industry. The committee also believes that granting long-term restricted stock awards aligns the executive officers' interests directly with those of our stockholders, as the executive officers will realize greater or lesser value based on our stock price during the performance and vesting period, which will parallel that of our stockholders over the same period. The CHC Committee further believes the restricted stock awards focus our NEOs on our long-term performance and discourages excessive risk-taking in the short-term.

**Five Year Performance Share Award Plan**

In February 2025, the CHC Committee adopted the Five Year Performance Share Award Plan (the "Five Year Plan") based on a recommendation from Meridian to better align our executive compensation program with our peers and based on management's discussions with investors. The Five Year Plan enhances our long term incentive compensation program by adding additional long term performance metrics and extending the vesting of earned awards to five years. Messrs. Edwards, Wheeler, Miller and Niswonger are eligible to participate in the Five Year Plan.

Component 1 of the Five Year Plan is a one time grant of restricted stock with a target award of $500,000. The target restricted stock award is divided into two elements of $250,000, each with its own specified five year target performance metric. Either or both of these elements may be earned if the target performance metric for that element is achieved no later than the fiscal year ending December 31, 2029. The performance metrics for the two elements are Revenue and Adjusted EBITDA. The CHC Committee will determine if either or both of the performance metrics are met by reference to the Company's annual earnings releases and/or financial statements. The performance metric must be met at least 90% for the restricted stock to be earned with respect to each element, without proration. Additional shares will not be awarded if the targets are exceeded.

Component 2 of the Five Year Plan is an annual award of restricted stock each year for five years that will be earned if the annual performance metric is met. The performance metric for Component 2 is a target adjusted general and administrative expense as a percentage of revenue, to be set by the CHC Committee each year for five years. See *"Additional Information – Use of Non-GAAP Financial Measures"* for a reconciliation of adjusted general and administrative expense as a percentage of revenue to the most directly comparable GAAP measure.

The annual award target is $150,000 per year, and will be earned if the annual target performance metric does not exceed 105%, without proration. Additional shares will not be awarded if the performance metric is exceeded.

The number of earned shares under Components 1 and 2 will be based on the closing price of our common stock on the date of certification of the achievement of the specified performance metric. Issuance of the restricted stock is generally subject to the NEO's continued employment on the vesting date. Any shares of earned restricted stock awarded under the Five Year Plan will vest on April 20, 2030 or, if earlier, upon the NEO's death.

Awards are subject to clawback under the terms of our recoupment policies.

For 2025, the CHC Committee determined not to adjust the base salaries of our NEOs to weight their compensation more heavily toward incentive equity compensation, with the objective of further aligning the compensation of our executives with stockholder value.

In consultation with our Chief Executive Officer and Chief Financial Officer, in February 2025, the CHC Committee considered corporate goals and objectives for our named executive officers for the 2025 fiscal year. Based on management's strategic and operational goals and considering management's short- and long-term budgets and projections, the CHC Committee established an Adjusted EBITDA target of $555.8 million as the 2025 performance metric for our NEOs' performance-based incentive awards, to be adjusted throughout the year for the impact of acquisitions. The committee determined that the performance goal was reasonable, but would be challenging given macroeconomic headwinds and projections for our industry.

The CHC Committee set target performance-based incentive cash awards for each NEO as set forth in the table below. Consistent with base salary, the CHC Committee determined not to adjust performance-based incentive cash awards of our NEOs to weight their compensation more heavily toward incentive equity compensation. The target awards were increased for 2025 to bring compensation levels into alignment with the Company's peers, to compensate our officers based on their increasing responsibilities due to Company growth and expanding service categories and to encourage our executive team to continue to focus its efforts on further increasing Company growth and creating stockholder value. Thresholds remained unchanged. The amount of each NEO's earned incentive cash award was equal to the NEO's target award multiplied by the percentage of the Adjusted EBITDA target achieved. No incentive award would be earned if the Company's actual Adjusted EBITDA during 2025 was less than 50% of the target, as adjusted for acquisitions, and awards were capped at 200% of target. Unless otherwise determined by the CHC Committee, payment of any incentive cash award is generally subject to the NEO remaining employed through the payment date. Incentive cash awards are subject to clawback under the terms of our recoupment policies.

In February 2026, the CHC Committee met to review the results of the Company's performance against the target Adjusted EBITDA performance metric. The Company's final Adjusted EBITDA target, as adjusted for the impact of acquisitions during the year, was $555.8 million. Actual Adjusted EBITDA was $518.5 million, or approximately 93% of target.

The following table reflects each NEO's 2025 target cash incentive award, earned cash incentive award and earned cash incentive award as a percentage of total compensation.

The performance-based incentive cash awards earned by our NEOs for 2025 are included in the "Non-Equity Incentive Plan Compensation" column of the *Summary Compensation Table* below.

**2025 Performance-Based Incentive Equity Awards**

In February 2025, the CHC Committee met to consider and finalize the performance metric for our 2025 annual performance-based incentive equity awards. The committee determined, for the reasons outlined in *"Section 3 – Elements of Our Compensation Program – Performance-Based Cash Incentives"* above, to use a one-year performance metric of Adjusted EBITDA. The target chosen by the CHC Committee for the incentive equity award program was the same as that chosen for the incentive cash award program. In order to achieve a balance between setting an annual performance metric and its desire to align the interests of our NEOs with the long-term interests of our stockholders, the CHC Committee adds a time-vesting component to the performance-based equity awards. The performance-based restricted stock awards actually earned by an executive may be above or below the target award, based on the degree to which the performance metric is met. Similar to performance-based cash awards, no equity award would be earned if the Company's actual Adjusted EBITDA during 2025 was less than 50% of the target, as adjusted for acquisitions, and awards were capped at 200% of target. Target awards are based on a number of shares rather than a dollar amount, so that the potential value of the award fluctuates with the price of our common stock during both the performance period, the vesting period and thereafter, aligning executive compensation with stockholder value. Incentive equity awards are subject to clawback under the terms of our recoupment policies.

In February 2026, the CHC Committee met to review the results of the Company's financial performance against the target performance metric. Consistent with the incentive cash award program, the Company's final Adjusted EBITDA target, as adjusted for the impact of acquisitions during the year, was $555.8 million. Actual Adjusted EBITDA was $518.5 million, or approximately 93% of target. Due to the increase in the price of our common stock between the grant date ($170.99) and the date upon which the award was earned ($319.99), the value of the NEOs equity awards correspondingly increased in alignment with stockholder value.

1. The grant date fair value was determined by multiplying the closing price of the Company's common stock on February 25, 2025 ($170.99) by the number of target shares.

2. The earned fair value was determined by multiplying the closing price of the Company's common stock on February 24, 2026 ($319.99) (the date of certification of the achievement of the performance metric) by the number of shares awarded. The restricted stock vests in equal installments over two years (subject to continued employment). The actual value on the vesting dates will be based on the closing prices of the Company's common stock on those dates.

**2025 Performance-Based Restricted Stock Awards – Five Year Plan**

In February 2025, in connection with the adoption of the Five Year Plan, the CHC Committee finalized the performance metric for Component 2 restricted stock awards under the Five Year Plan. Component 2 of the Five Year Plan is an annual award of restricted stock each year for five years that is earned if the annual performance metric is met. The performance metric for Component 2 is a target adjusted general and administrative expense as a percentage of revenue. The annual award target is $150,000 per year, and is earned if the annual target performance metric does not exceed 105%, without proration. Additional shares are not awarded if the performance metric is exceeded. The number of earned shares under Component 2 is based on the closing price of our common stock on the date of certification of the achievement of the performance metric.

On February 24, 2026, the CHC Committee met to review the results of the Company's performance against the target performance metric. The performance metric for Component 2 of the Five Year Plan was set at adjusted general and administrative expense as a percentage of revenue of no more than 13.7%. Actual adjusted general and administrative expense as a percentage of revenue was 13.5%, or approximately 102.4%, and the CHC Committee certified achievement of the performance metric. The shares awarded will not vest until April 20, 2030, so that the potential value of the award will fluctuate with the price of our common stock during the vesting period.

The following table reflects each NEO's 2025 target Component 2 incentive restricted stock award and earned incentive restricted stock award.

The earned fair value was determined by multiplying the closing price of the Company's common stock on February 24, 2026 ($319.99) (the date of certification of the achievement of the performance metric) by the number of shares awarded. Issuance of the restricted stock is generally subject to the NEO's continued employment on the vesting date. Any shares of earned restricted stock awarded under the Five Year Plan will vest on April 20, 2030 or, if earlier, upon the NEO's death. Awards are subject to clawback under the terms of our recoupment policies. The actual value on the vesting date will be based on the closing price of the Company's common stock on that date.

**Compensation Changes after December 31, 2025**

**Base Salary.** For 2026, the CHC Committee determined not to adjust the base salaries of our NEOs to weight their compensation more heavily toward incentive equity compensation, with the objective of further aligning the compensation of our executives with stockholder value.

**Incentive Cash Compensation.** The CHC Committee continued our performance-based incentive cash program for 2026 on substantially the same terms as the program approved by our stockholders in 2025. For all incentive-based compensation, the threshold is 50% of target and the maximum is 200% of target. Similar to base salary, for 2026 CHC Committee determined not to adjust the incentive cash compensation targets of our NEOs to weight their compensation more heavily toward incentive equity compensation in an effort to further align the compensation of our executives with stockholder value.

**Incentive Equity Compensation.** For the reasons noted above, for 2026 the CHC Committee increased the target value of annual restricted stock awards for each NEO. In addition, certain executives are eligible to receive restricted stock awards under the Five Year Plan described in *"Five Year Performance Share Award Plan"* above.

For the annual incentive restricted stock awards, the CHC Committee determined that each NEO is eligible to receive the target number of shares of restricted stock set forth in the table below, based on the achievement of Adjusted EBITDA performance goals. The performance metric and terms of the equity awards are the same as those used for incentive cash awards. If restricted stock is earned, it will vest in two equal installments on April 20, 2028 and April 20, 2029, generally subject to the NEO's continued employment on each vesting date. The restricted stock vests in full in the event of an NEO's death. The CHC Committee has discretion to adjust any award, even if fully earned.

**Section 5 – Other Compensation and Policies**

**Perquisites**

The Company offers no perquisites to our NEOs that are not generally available to salaried employees other than auto leases or allowances (including insurance) and cell phones, which are set forth in the "All Other Compensation" column of the *Summary Compensation Table* below. These perquisites do not play a significant role in our executive compensation program. From time to time, our NEOs may travel by Company-paid chartered aircraft services to facilitate travel that is directly related to the performance of their duties.

**Post-Termination Compensation**

Our severance arrangements with our named executive officers are limited. If an NEO's employment is terminated due to retirement or disability, the CHC Committee may, in the exercise of its discretion, determine to accelerate vesting of restricted stock awards and to waive any limitations placed on performance-based incentive cash awards. If an NEO's employment is terminated due to the executive's death, all earned but unvested restricted stock awards automatically vest in full.

The Company has entered into an employment agreement with Mr. Edwards, the terms of which are more fully described below in *"Employment Agreement with Jeffrey W. Edwards."* Under the terms of his employment agreement, Mr. Edwards is entitled to certain severance benefits in the event his employment is terminated by the Company without "Cause" or by Mr. Edwards for "Good Reason," as defined in the employment agreement. These benefits include salary continuation, a lump sum cash payment and payment of earned but unpaid or unissued performance-based incentive awards. Details of the arrangement with Mr. Edwards are described in

more detail in *"Potential Payments Upon Termination"* and *"Payments to Named Executives Upon a Change in Control"* below.

In August 2025, we entered into Change in Control Agreements with each of our executives, which provide for certain severance payments in the event that an executive's employment is terminated within 24 months of a change in control. See *"Executive Compensation- Payments to Named Executive Officers upon a Change in Control."*

**Retirement Benefits**

The Company does not provide pension, retirement or similar benefits to its NEOs other than our 401(k) program, which is available to all of our qualifying employees, and our non-qualified deferred compensation plan, which allows our executive officers and other highly compensated employees to defer a portion of their eligible compensation above 401(k) plan limits.

**Equity Grant Practices**

The CHC Committee's practice is to grant equity awards to our NEOs during the first quarter of each year, typically in late February when the CHC Committee has the financial information necessary to establish appropriate performance award criteria for the current year and to certify the achievement of the performance criteria for the prior fiscal year. Equity awards to other employees are granted by the CHC Committee in April of each year, except in special circumstances where awards may be made at other times during the year. We do not engage in the practice of timing grants with the release of non-public information nor do we time the disclosure of material non-public information for the purpose of affecting the value of executive compensation. In 2025, the Company did not grant stock options to any NEO during any period beginning four business days before and ending one business day after the filing of any Company periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any Company current report on Form 8-K that disclosed any material nonpublic information. We did not grant stock options or other stock-based compensation other than restricted stock described herein.

**Taxes**

We do not provide tax gross-ups for perquisites provided to our NEOs or for excise tax applied pursuant to Section 280G of the Internal Revenue Code. None of our NEOs received a tax gross-up for any benefits in 2025.

**Stock Ownership Policy**

The CHC Committee has established a Stock Ownership Policy for Executive Officers for the purpose of requiring executives to hold our common stock with a value equal to a multiple of base salary to strengthen their alignment with the interests of our stockholders and to promote achievement of long-term business objectives.

The following shares qualify for purposes of the ownership requirement: shares owned by the executive or held jointly with a spouse; shares held in a trust established for the benefit of the executive or his or her family; and shares of unvested restricted stock, excluding performance-based shares for which the performance metric has not been met. If an executive chooses to meet the ownership requirement using unvested shares of common stock issued under the Company's incentive plan, the stock is valued for purposes of meeting the requirement at

the greater of the closing price on the grant date or the closing price on the date on which ownership is measured (the last trading day of the year of measurement), unless the CHC Committee determines that the closing price on the measurement date is not representative. Once an executive has satisfied the ownership requirement, a decrease in share price absent a sale of shares by the executive will not result in noncompliance with the policy. An executive has five years from the date of being named as an executive officer, or if later, the date of an increase in the number of shares required to be held (e.g., due to an increase in salary), to meet this requirement. If an executive officer does not meet the ownership requirement at the measurement date, the executive is prohibited from selling any of our common stock, and fifty percent (50%) of his or her annual incentive bonus will be paid in the form of common stock in lieu of cash. All of our executive officers held shares in excess of the requirements as of December 31, 2025. In 2025, none of our executives had Rule 10b5-1 trading arrangements in place.

**Clawback Policies**

The Board of Directors has adopted incentive compensation recoupment policies, or "clawback" policies, the purpose of which is to deter our executives from taking actions that could potentially harm the Company and our stockholders. Our mandatory clawback policy applies to all incentive cash and equity compensation paid to any current or former executive officer. Under the policy, if we are required to restate our financial statements due to material noncompliance with financial reporting requirements under applicable securities laws, the Company will recover from each executive officer the amount of any incentive-based compensation paid during the three-year period preceding the restatement in excess of what would have been paid if calculated under the restated financial statements, without regard to taxes paid by the executive officer or the Company. The Company will not indemnify any executive officer against the loss of any incorrectly awarded or otherwise recouped incentive compensation. The Policy overrides any contrary provisions of any employment agreements, compensation plans or arrangements, or award agreements. The CHC Committee may decline to recoup incentive compensation if the committee determines that recovery is impracticable under limited exceptions. A copy of the policy is posted on our website at https://investors.installedbuildingproducts.com/corporate-governance.

In addition to our mandatory clawback policy, the Board has adopted a discretionary clawback policy. The discretionary policy provides that if the CHC Committee determines that an executive officer has engaged in grossly negligent or intentional misconduct that was a significant contributing factor to an accounting restatement, any significant increase in the value of such executive's incentive compensation or any substantial financial or reputational harm to the Company, the committee may (i) recover any incentive-based compensation awards paid prior to the date of determination, (ii) cancel any incentive compensation not paid or otherwise settled prior to the date of the determination, and (iii) withhold or eliminate any incentive compensation that could be paid or awarded after the date of determination. The CHC Committee may also dismiss the executive officer, authorize legal action against the executive for breach of fiduciary duty or other violation of law, and take such other action as the committee may deem appropriate.

1. Amounts in this column for 2025 represent the aggregate grant date fair value of performance-based restricted stock awards granted February 24, 2025 based on 2025 performance metrics, performance-based shares awarded under the Component 2 of the Five Year Plan and the fixed monetary one time award under Component 1 of the Five Year Plan, computed in accordance with FASB ASC Topic 718. The grant date fair value of the performance-based restricted stock awards was determined by multiplying the number of shares of common stock that would be earned based on the probable outcome of the performance conditions (i.e., target) by the closing price of $170.99 on the grant date. The amounts shown in this column do not reflect compensation actually received by the NEOs. The actual value, if any, that an NEO may realize from an award is contingent upon the satisfaction of the vesting conditions and the value of the underlying shares if and when the award vests. Thus, the value eventually realized by the NEOs is unlikely to equal amounts shown in these columns. The grant date fair value for each NEO, assuming the achievement of maximum performance levels, is as follows: Mr. Edwards, $9,250,188; Mr. Miller, $3,370,184; Mr. Wheeler, $2,850,032; Mr. Hire, $650,104; and Mr. Niswonger, $1,800,154.

1. The amounts shown reflect the threshold, target and maximum amounts that each NEO was eligible to receive for 2025 based on achievement of the Adjusted EBITDA performance target established by the CHC Committee. Actual payouts are reported in the Summary Compensation Table under the "Non-Equity Incentive Plan Compensation" column. The material terms of the 2025 non-equity incentive awards are described above under *"2025 Performance-Based Incentive Cash Award."* A reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure may be found under the heading *"Additional Information – Use of Non-GAAP Financial Measures."* 

2. The amounts shown reflect the threshold, target and maximum amounts that each NEO was eligible to receive for 2025 performance-based award on achievement of the Adjusted EBITDA performance target by the CHC Committee. The amounts shown for Component 1 of the Five Year Plan are the target based on achievement of the Revenue and Adjusted EBITDA performance metrics established by the CHC Committee, which will be paid out in stock in such number of shares that translate into the disclosed dollar amount at the time of payout. The amounts shown for Component 2 of the Five Year Plan are the target based on achievement of the adjusted general and administrative expense performance metric established by the CHC Committee, which will be paid out in stock in such number of shares that translate into the disclosed dollar amount at the time of payout. Actual payouts are reported in *"Section 4 – What We Paid in 2025 – 2025 Performance-Based Incentive Equity Awards*." The material terms of the 2025 equity incentive awards are described above under *"2025 Performance-Based Incentive Equity Awards"* and *"2025 Performance-Based Restricted Stock Awards - Five Year Plan."* Reconciliations of Adjusted EBITDA and Adjusted General and Administrative Expense as a Percentage of Revenue to their most directly comparable GAAP measures may be found under the heading *"Additional Information – Use of Non-GAAP Financial Measures."* 

3. Amounts in this column for 2025 represent the aggregate grant date fair value of performance-based restricted stock awards, computed in accordance with FASB ASC Topic 718. The grant date fair value for the performance-based awards was determined by multiplying the closing price of the Company's common stock on February 25, 2025 ($170.99) by the number of shares that would be earned based on the probable outcome of the performance conditions (i.e., target). The grant date fair value for each component of the Five Year Plan was based on the target payout value as established by the CHC Committee on February 25, 2025.

1. The value realized on vesting was determined by multiplying the closing price of our common stock on the vesting date of April 17, 2025 ($158.24) by the number of shares vested.

**Pension Benefits**

We do not provide any qualified or non-qualified defined pension benefit plans for our NEOs. The CHC Committee may elect to adopt such plans in the future if it determines that doing so best serves the interests of the Company and our stockholders.

**Non-Qualified Deferred Compensation**

In 2020, we adopted a non-qualified deferred compensation plan to allow our executive officers and other highly compensated employees to defer a portion of their eligible compensation above the limits in our 401(k) plan. The Company adopted a "rabbi trust" to fund benefits under the plan, which is an irrevocable trust, but is subject to the claims of the Company's creditors. Under the terms of the plan, eligible individuals, including our named executive officers, may annually elect to defer a portion of eligible compensation, primarily base salary, commission and

cash bonuses. Deferral elections are irrevocable once made and remain in effect for the calendar year of the election. The Company may elect to provide a discretionary matching contribution or a discretionary non-elective contribution in any year, but to date has not done so. Participants are immediately vested in contributions and earnings from contributions. Company matches and non-elective contributions and associated earnings vest after three years of service (except in the event of a change in control or when the participant reaches age 65, in which case both Company matches and non-elective contributions vest immediately). Participants may elect among a number of distribution options, including (i) either lump sum or payments over two to ten years upon separation from service; and (ii) lump sum or payments over two to ten years of all or a portion of the amount deferred in a given year, after at least three years following the year of deferral.

The table below sets forth information concerning the amount of each NEO's compensation that was deferred under our non-qualified deferred compensation plan in 2025.

**Employment Agreements, Severance and Change in Control Benefits**

**Employment Agreement with Jeffrey W. Edwards**

In November 2013, we entered into an employment agreement with Mr. Edwards pursuant to which he agreed to serve as our Chief Executive Officer and President for an initial employment term through November 1, 2016. The agreement provides Mr. Edwards with a minimum annual base salary of $600,000, subject to adjustment by the CHC Committee, and an opportunity to participate in our annual incentive programs, as well as our employee benefit plans and programs in effect from time to time.

The agreement has been amended and restated (i) to extend Mr. Edwards' employment term to April 15, 2026 with automatic five-year renewals unless either party provides at least 90 days' prior notice of non-renewal, (ii) to provide that Mr. Edwards must give 180 days' prior written notice of a voluntary termination of employment without "Good Reason" (as defined in the employment agreement), (iii) to provide for a reduction in severance payments that would exceed tax laws governing parachute payments and (iv) to modify certain of Mr. Edwards' severance payments. We also amended and restated Mr. Edwards' employment agreement in August 2025 to remove all restrictive covenants and certain change in control payment provisions from the agreement, which are now included in our Change in Control Agreement with Mr. Edwards, and to make certain minor revisions, some of which were to make Mr. Edwards' employment agreement consistent with the terms of the Change in Control Agreement. For a description of the Change in Control Agreement, see *"Payments to Named Executive Officers Upon a Change in Control."*

Mr. Edwards is required to devote the amount of his business time necessary to conduct Company business and affairs and to use his best efforts to perform his duties as our Chief Executive Officer and President. However, to the extent such activities do not create a conflict of interest or substantially interfere with the performance of Mr. Edwards' duties and responsibilities to the Company, he may (i) manage his personal and family financial and legal affairs, (ii) participate in charitable, civic, educational, professional, community and industry affairs (including serving on boards or committees of such entities, including the Columbus Partnership, Downtown Columbus Inc. and Nationwide Children's Hospital, among others) and (iii) continue to engage in non-competitive activities for a real estate development business in which he participated prior to entering into his employment agreement.

Mr. Edwards is entitled to receive certain severance benefits in the event of termination of his employment by us without "Cause" or if Mr. Edwards terminates his employment for "Good Reason," in each case as defined in the employment agreement. See *"Potential Payments Upon Termination"* and *'Payments to Named Executive Officers Upon a Change in Control"* below for a summary of these severance benefits. In the event of Mr. Edwards' termination for any reason, we are required to pay him for his accrued and unpaid vacation as of the date of termination.

**Potential Payments Upon Termination**

None of our named executive officers other than Mr. Edwards are entitled to benefits (other than vested benefits and awards) upon a resignation or termination, except that if an NEO's employment is terminated due to retirement or disability, the CHC Committee may, in the exercise of its discretion, accelerate vesting of restricted stock awards and waive any limitations placed on performance-based cash awards. If an NEO's employment is terminated due to the executive's death, all earned but unvested restricted stock awards automatically vest in full.

If a named executive officer engages in "detrimental activity" (as defined in the 2023 Omnibus Incentive Plan), prior to or one year following vesting of any restricted stock, the CHC Committee may direct that all unvested restricted stock be forfeited and that the executive pay to the Company the fair market value of vested restricted stock (valued as of the vesting date).

**Payments to Mr. Edwards upon Termination without Cause or Resignation for Good Reason**

If we terminate Mr. Edwards without Cause or Mr. Edwards terminates his employment for Good Reason, then subject to his compliance with certain restrictive covenants and upon his signing a release of claims, we are required to pay Mr. Edwards (i) base salary continuation payments for 18 months; (ii) any earned but unpaid or unissued annual incentive cash bonus or restricted stock award with respect to the performance year prior to the year of termination; and (iii) a lump sum cash payment equal to 1.5 times the dollar value of the total target incentive cash award ("Target Cash Award") established by the CHC Committee for the year of termination. Mr. Edwards' employment agreement was amended in August 2025 so that for termination of employment following a change in control his rights to severance payments are governed by the Change in Control Agreement described below.

"Cause" generally means: (i) conviction of or a plea of guilty to a felony; (ii) willful commission of an act of fraud, dishonesty or other willful misconduct in the course of Mr. Edwards' duties having a significant adverse effect on the Company; (iii) willful failure to perform prescribed duties after the Company has delivered a written demand for performance; or (iv) any material breach by Mr. Edwards of the employment agreement that remains uncured for 30 days.

"Good Reason" generally means any of the following events with respect to Mr. Edwards occurring without his consent: (i) a diminution in base salary; (ii) a diminution in duties, authorities or responsibilities; (iii) a requirement that Mr. Edwards report to and be subject to the authority of an officer r employee of the Company other than the Board; (iv) a relocation of a primary work location by more than 20 miles; or (v) any material breach by the Company of the employment agreement.

**Payments to Named Executive Officers upon a Change in Control**

We have entered into Change in Control Agreements with our executives, which provide for certain payments and benefits in the event of a change in control (as defined in the agreement) and termination of the executive's employment within 24 months of such change in control. The terms of the agreement are limited to involuntary termination of the executive by the Company or surviving entity without "cause" or resignation by the executive for "good reason."

"Cause" includes conviction of a felony; willful acts of fraud or dishonesty or other willful misconduct in the course of duty that has a significant adverse effect on the Company; willful failure to perform duties or material breach of any employment agreement or the Change in Control Agreement.

"Good Reason" includes diminution of base salary, target annual performance-based cash bonus or other incentive compensation opportunity; diminution in authority, duties, or responsibilities; a requirement that the executive report to any person other than the Board of Directors or chief executive officer; relocation of executive's principal place of employment by 20 miles or more, or a material breach of the Change in Control Agreement.

Separation benefits include:

&nbsp;&nbsp;&nbsp;&nbsp;• cash payments totaling 300% of each NEO's base salary and target performance-based cash bonus;

&nbsp;&nbsp;&nbsp;&nbsp;• continued participation in our health plan for 18 months at the same rate that applies to senior executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;• vesting of any unearned performance-based incentive equity awards at the target level;

&nbsp;&nbsp;&nbsp;&nbsp;• vesting of any earned but unvested performance-based incentive equity awards; and

&nbsp;&nbsp;&nbsp;&nbsp;• termination of all restrictive covenants applicable to the NEO.

Any separation benefits are "double trigger," meaning that they require the occurrence of both a change in control and a qualifying event (termination of the executive's employment under the conditions set forth above) before they become effective.

NEOs are not entitled to tax "gross-up" or similar payments on any amounts received under the Change in Control Agreements to account for excise taxes on "parachute payments" that are defined in Sections 280G and 4999 of the Code. Compensatory payments and benefits to be received under the agreement may be reduced in the event that the aggregate payments to any NEO would result in an excess payment, which is 300% or more of average annual compensation. The reduction would be applied to limit payments to one dollar below this amount. This reduction preserves the tax deduction for the Company or the surviving entity under Section 280G of the Code and avoids the imposition of a 20% excise on the NEO under Section 4999 of the Code. This reduction does not apply, however, in the event that the aggregate payments due under the agreement, net of the 20% excise tax under Section 4999 of the Code, would be greater than the aggregate payments received after applying the reduction.

The terms of the Change in Control Agreements include certain restrictive covenants. While employed and for two years after termination of his employment, each NEO is subject to non-competition and customer and employee non-solicitation covenants. In addition, each executive is subject to confidentiality restrictions that remain in effect during employment and thereafter.

**Payments to NEOs upon Death, Retirement or Disability, Change in Control or Termination** 

The following table summarizes the value of any cash awards or unvested restricted stock that would vest in the event of an NEO's death, retirement or disability; an NEO's termination without cause or for good reason; or a change of control, assuming such event occurred on December 31, 2025. The value was determined by multiplying the closing price of our common stock on December 31, 2025 ($259.39) by the number of shares that would have vested on such date.

1. If an NEO's employment is terminated due to death, retirement or disability, the CHC Committee may also, in the exercise of its discretion, determine to waive any limitations placed on performance-based incentive cash awards. The CHC Committee also retains discretion to fully vest stock awards on a Change in Control.

2. Values are based on the Change of Control Agreements described above. In some situations, the payouts potentially would be lower than the amounts reported in this column due to the cap in the Change in Control Agreements on payments that exceed certain limits under Section 280G of the Code.

3. Value is based on Mr. Edwards' employment agreement described above.

**Chief Executive Officer Pay Ratio**

In accordance with SEC rules, we are providing the ratio of the annual total compensation of our Chief Executive Officer to the annual total compensation of our median employee.

For 2025:

• the annual total compensation of our median employee was $62,164;

• the annual total compensation of our CEO was $6,596,834; and

• the ratio of the annual total compensation of our CEO to the annual total compensation of our median employee was approximately 106 to 1.

The methodology and material assumptions, adjustments, and estimates that we used for these calculations were as follows.

We determined that, as of our testing date of December 31, 2025, our employee population consisted of 10,448 employees, including our CEO. After taking into consideration the adjustments permitted by SEC rules (by excluding 244 contractual employees and 96 employees, 80 of whom were hired after the final pay period in December 2025, and 16 of whom were union employees who remain active in our system but performed no work in 2025), our measurable employee population was 10,011 individuals. All of our employees are located in the United States.

With respect to the annual total compensation used to determine our "median employee," we used a consistently applied measure, which we applied separately for salaried and hourly employees. For salaried employees, we

used base salary rate. For hourly employees, we estimated annual wages based on hourly wage rate and normal weekly schedule. For piece rate employees, we used earned production wages. For salespersons, wages included commissions. We annualized the compensation of employees who were employed on our December 31, 2025 testing date, but who worked less than a full year.

Once we identified our median employee, we combined all of the elements of the employee's compensation for 2025 in accordance with SEC rules, resulting in annual total compensation of 62,164. For the annual total compensation of our CEO, we used the amount reported in the "Total" column of the *Summary Compensation Table.* 

The SEC rules for identifying the median employee and calculating the pay ratio allow companies to choose from a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their varied employee populations and compensation practices. The pay ratio reported by other companies may not be comparable to our reported pay ratio, as other companies have differing employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their pay ratios.

Our pay philosophy is to pay our workforce competitively. We offer competitive pay based on industry specific compensation practices across our local markets, taking into account job responsibilities and individual performance. We believe both our CEO and our employee compensation programs are structured to attract and retain valuable talent necessary to drive profitable operations and enhance stockholder value.

**Pay Versus Performance**

The following information has been prepared in accordance with the SEC's pay versus performance rules under the Exchange Act. The tables and related disclosures contain information about the relationship between our executive compensation actually paid (as defined by SEC rules) and certain Company financial performance measures. The CHC Committee did not consider this information when making its executive compensation decisions in 2025 or in setting target compensation for 2026. For further information about how we align executive compensation with Company performance, see *"Compensation Discussion and Analysis."* The amounts in the tables below are calculated in accordance with SEC rules and may not represent amounts actually earned or realized by our Principal Executive Officer ("PEO") or Non-PEO Named Executive Officers.

5. For each of the five fiscal years presented in the table, total shareholder return was calculated in accordance with Item 402(v) of Regulation S-K under the Exchange Act. For purposes of this pay versus performance disclosure, the peer group used was the S&P 600 Building Products Sub Industry GICS Level 4 Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2025. The comparison assumes $100 was invested for the period starting December 31, 2020, through the end of the listed year in the Company and in the S&P 600 Building Products Sub Industry GICS Level 4 Index, respectively.

6. Net income is rounded to the nearest hundred thousand.

7. The CHC Committee has selected Adjusted EBITDA as the most important financial performance measure used to link our executive compensation to Company performance. See *"Additional Information – Use of Non-GAAP Financial Measures"* for a reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure. Adjusted EBITDA is rounded to the nearest hundred thousand.

**Stock Ownership Information**

**Stock Ownership Table**

The following table shows the beneficial ownership of our common stock as of March 23, 2026 held by:

• each person whom we know to beneficially own more than 5% of our outstanding common stock;

• each director;

• each named executive officer; and

• all directors and executive officers as a group.

Unless otherwise indicated, the address of each director and executive officer is c/o Installed Building Products, Inc., 495 South High Street, Suite 50, Columbus, Ohio 43215.

The number of shares of common stock "beneficially owned" is determined under certain SEC rules and is not necessarily indicative of ownership for any other purpose. Under these rules, beneficial ownership includes shares as to which the stockholder has sole or shared voting power or investment power and shares as to which the stockholder has the right to acquire beneficial ownership within 60 days after March 23, 2026, including shares that could be purchased by the exercise of options or warrants. Unless otherwise indicated, to our knowledge all persons named in the table have sole voting and investment power with respect to their shares of our common stock. Each stockholder's percentage ownership is based on 26,938,333 shares of common stock outstanding as of March 23, 2026, except to the extent indicated in the footnotes.

In each of September and November 2023 and May 2024, IBS, an investment vehicle owned by Mr. Edwards and his siblings, entered into prepaid variable forward sale contracts with an unaffiliated third party buyer. In each of the September and November transactions, IBS pledged 450,000 shares, or 900,000 shares in the aggregate, and in the May transaction, IBS pledged 250,000 shares (collectively, the "Pledged Shares") of our common stock to secure its obligations under the contracts, but retained ownership, dividend and voting rights in the Pledged Shares. The contracts obligate IBS to deliver to the buyer, on the applicable settlement date for each component described below, up to one hundred percent of the number of Pledged Shares for such component or, at IBS' option, an equivalent amount of cash.

In August 2025, IBS and the buyer entered into an amendment to the September 2023 forward sale contract

(the "First Amendment September Agreement") and the May 2024 forward sale contract (the "First Amendment May Agreement" and collectively, the "2025 Amendment Agreements"). The First Amendment September Agreement amended certain terms of one of the forward sale contracts entered into in September 2023, covering 225,000 shares of our common stock, including (i) extending the range of settlement dates for the components from August 14, 2025 through August 22, 2025 to the new settlement dates from May 24, 2027 through June 4, 2027, (ii) amending the floor price and cap prices, and (iii) increasing the number of components from 7 to 9, with appropriate adjustments for the number of shares to be delivered on the respective settlement date for each component. The First Amendment May Agreement amends certain terms of one of the forward sale contracts entered into in May 2024, covering 125,000 shares of our common stock, including (i) extending the range of settlement dates for the components from August 14, 2025 through August 22, 2025 to the new settlement dates from November 16, 2026 through November 23, 2026, (ii) amending the floor and cap prices, and (iii) reducing the number of components from 7 to 6, with appropriate adjustments for the number of shares to be delivered on the respective settlement date for each component.

The number of shares of our common stock to be delivered to the buyer on the settlement date (or on which to base the amount of cash to be delivered to the buyer on such settlement date) under the 2025 Amendment Agreements is to be determined as follows: (a) if the volume-weighted average price of our common stock on the designated valuation date for the applicable component (each, a "Settlement Price") is less than or equal to $257.6320 (the "2025 Amended Floor Price"), IBS will deliver to the buyer all of the Pledged Shares for the applicable component; (b) if such Settlement Price is greater than the 2025 Amended Floor Price but less than or equal to $319.4637 (the "2025 Amended Cap Price"), IBS will deliver to the buyer the number of shares equal to 100% of the Pledged Shares for the applicable component multiplied by a fraction, the numerator of which is the 2025 Amended Floor Price and the denominator of which is such Settlement Price and (c) if such Settlement Price is greater than the 2025 Amended Cap Price, IBS will deliver to the buyer the number of shares equal to 100% of the Pledged Shares for the applicable component multiplied by a fraction, the numerator of which is the 2025 Amended Floor Price plus the excess of such Settlement Price over the 2025 Amended Cap Price, and the denominator of which is such Settlement Price. Each component is exercisable on the same date as it expires, and the expiration dates for the components occur from May 24, 2027 through June 4, 2027 under the First Amendment September Agreement and November 16, 2026 through November 23, 2026 under the First Amendment May Agreement.

In March 2026, IBS and the buyer entered into a second amendment to the September 2023 forward sale contract (the "Second Amendment September Agreement") and the May 2024 forward sale contract (the "Second Amendment May Agreement" and collectively the "2026 Amendment Agreements"). The reference price for the 2026 Amendment Agreements was $314.06. The September Amendment Agreement amends certain terms of one of the forward sale contracts entered into in September 2023, covering 225,000 shares of our common stock, including (i) extending the range of settlement dates for the components from March 9, 2026 through March 13, 2026 to the new settlement dates from May 24, 2027 through June 4, 2027, (ii) amending the floor price and cap prices; and (iii) increasing the number of components from 5 to 9, with appropriate adjustment for the number of shares to be delivered on the respective settlement date for each component. The Second Amendment May Agreement amends certain terms of one of the forward sale contracts entered into in May 2024, covering 125,000 shares of our common stock, including (i) extending the range of settlement dates for the components from March 9, 2026 through March 13, 2026 to the new settlement dates from May 24, 2027 through June 4, 2027, (ii) amending the floor and cap prices, and (iii) increasing the number of components from 5 to 9, with appropriate adjustments for the number of shares to be delivered on the respective settlement date for each component.

The number of shares of our common stock to be delivered to the buyer on the settlement date (or on which to base the amount of cash to be delivered to the buyer on such settlement date) under the 2026 Amendment Agreements is to be determined as follows: (a) if the volume-weighted average price of our common stock on the designated valuation date for the applicable component (each, a "Settlement Price") is less than or equal to $314.06 (the "2026 Amended Floor Price"), IBS will deliver to the buyer all of the Pledged Shares for the

applicable component; (b) if such Settlement Price is greater than the 2026 Amended Floor Price but less than or equal to $376.872 (the "2026 Amended Cap Price"), IBS will deliver to the buyer the number of shares equal to 100% of the Pledged Shares for the applicable component multiplied by a fraction, the numerator of which is the 2026 Amended Floor Price and the denominator of which is such Settlement Price and (c) if such Settlement Price is greater than the 2026 Amended Cap Price, IBS will deliver to the buyer the number of shares equal to 100% of the Pledged Shares for the applicable component multiplied by a fraction, the numerator of which is the 2026 Amended Floor Price plus the excess of such Settlement Price over the 2025 Amended Cap Price, and the denominator of which is such Settlement Price. Each component is exercisable on the same date as it expires, and the expiration dates for the components occur from May 24, 2027 through June 4, 2027 under the 2026 Amendment Agreements.

For the November 2023 transaction, the number of shares of our common stock to be delivered to the buyer on the settlement date (or on which to base the amount of cash to be delivered to the buyer on the settlement date) is determined as follows: (a) if the volume-weighted average price of our common stock on the designated valuation date for the applicable component (each, a "November Settlement Price") is less than or equal to $131.9962 (the "November Floor Price"), IBS will deliver to the buyer all of the Pledged Shares for the applicable component; (b) if such November Settlement Price is greater than the November Floor Price but less than or equal to $166.7321 (the "November Cap Price"), IBS will deliver to the buyer the number of shares equal to 100% of the Pledged Shares for the applicable component multiplied by a fraction, the numerator of which is the November Floor Price and the denominator of which is such November Settlement Price and (c) if such November Settlement Price is greater than the November Cap Price, IBS will deliver to the buyer the number of shares equal to 100% of Pledged Shares for the applicable component multiplied by a fraction, the numerator of which is the November Floor Price plus the excess of such November Settlement Price over the November Cap Price, and the denominator of which is such November Settlement Price. In connection with the entry into the forward contracts, IBS was entitled to receive aggregate net cash payments (amounts receivable by it upon entry into the forward contract) of $48,769,133. Each component is exercisable on the same date as it expires, and the expiration dates for the components occur from November 16, 2026 to November 23, 2026 under one contract and from May 24, 2027 to June 4, 2027 under the other.

Based on our review of the reports submitted to the SEC on EDGAR or otherwise furnished to us, we believe that in 2025 our directors, executive officers and persons who beneficially own more than ten percent of our common stock who were subject to Section 16(a) timely met all applicable filing requirements except as follows: one Form 4 filed late on April 22, 2025 by Mr. Edwards reporting one gift transaction that occurred on February 24, 2025 and one gift transaction that occurred on November 13, 2024.

Peter Edwards Jr., Anne Edwards and Michael Edwards are siblings of Jeff Edwards.* 

**Affiliate Purchases and Sales**

Our operating subsidiaries install building products in the ordinary course of their businesses for certain of our directors and executive officers or their affiliated entities. We also purchase goods or services from companies affiliated with our directors and executive officers. These transactions are on terms comparable to those that could be obtained in an arm's-length transaction with an unrelated third party. In addition to the sales described below, our employees provide certain administrative services to affiliates of the Edwards Investors, including information technology, human resources and communications management services, which are invoiced on an hourly basis. In 2025, our affiliate purchase and sale transactions were:

• Edwards Investors affiliates: sales $203,288, purchases $686,750

• Robert H. Schottenstein affiliates (including M/I Homes, Inc. and affiliated entities): sales $24,788,094

**Real Property Leases**

Our headquarters building in Columbus, Ohio is subject to a master lease agreement between an unrelated third party owner and The Edwards Companies, LLC, an entity affiliated with the Edwards Investors, to which we made rent payments. The lease will expire in 2026 in connection with the move to new corporate headquarters. In 2025, we paid $722,627 in base rent payments to The Edwards Companies, LLC.

In 2024, we entered into a lease agreement with an affiliate of the Edwards Investors in connection with the relocation of our corporate headquarters, which we currently expect to occur in the second quarter of 2026. No rent payments were made under the lease in 2025.

We lease two branch locations in Columbus, Ohio from an affiliate of Peter H. Edwards, an immediate family member of the Edwards Investors. We paid base rent payments for these facilities in 2025 of $285,385 and $154,209, respectively.

In each case under the applicable lease, we are also obligated to pay our proportionate share of certain common area maintenance charges, taxes, insurance premiums and other costs of operation, depending on the terms of the lease.

**Aircraft Lease and Ownership Agreement**

In 2019, we entered into an aircraft lease agreement with an affiliate of the Edwards Investors, pursuant to which we lease the use of an aircraft for business travel on a non-priority basis. The lease agreement automatically renews every 29 days unless terminated on ten days' notice by either party and is updated for current rental rate charges each year. In 2025, we paid lease payments, including operating expenses, of $347,788.

In 2024, we purchased a 35% interest in an aircraft to be used for business travel, together with an affiliate of the Edwards Investors, who purchased a 15% interest, and an unrelated third party, who owns the remaining interest. In connection with that transaction, we entered into an aircraft co-ownership agreement to govern the respective rights and obligations of the owners. The agreement continues until the aircraft is sold or the agreement is

**Share Repurchases**

On each of November 24, 2025, August 19, 2025 and March 7, 2025, as part of our stock buyback program, we entered into a share repurchase agreement with PJAM IBP Holdings, Inc. ("PJAM") for the purchase of 150,000, 200,000 and 100,000 shares, respectively, or a total of 450,000 shares, of our common stock in a privately-negotiated transaction (the "Share Repurchases"). The aggregate purchase price for the Share Repurchase in November 2025 was approximately $37.6 million, or $250.96 per share, which was the last reported price of our common stock on November 21, 2025, less a discount of 3.0%. The aggregate purchase price for the Share Repurchase in August 2025 was approximately $51.5 million, or $257.38 per share, which was the last reported price of our common stock on August 18, 2025, less a discount of 3.0%. The aggregate purchase price for the Share Repurchase in March 2025 was approximately $16.9 million, or $168.75 per share, which was the last reported price of our common stock on March 6, 2025, less a discount of 3.0%. Jeff Edwards, our Chief Executive Officer, has beneficial ownership of the shares held by PJAM, an Edwards Investors entity.

**Policies and Procedures for Related Party Transactions**

Our Board of Directors has adopted a Related Party Transaction Policy ("Policy") for the review and approval or ratification of certain related party transactions. The Policy is administered by the Audit Committee with the assistance of our General Counsel, Chief Financial Officer and Chief Accounting Officer.

The Policy applies to any transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the Company or one of our subsidiaries is a participant; the amount involved exceeds $120,000; and a Related Party (as defined below) had, has or will have a direct or indirect material interest. Any transaction meeting these criteria is a "Related Party Transaction."

Under the Policy, a "Related Party" is any person who: (i) is, or, at any time since the beginning of our last fiscal year, was, a director, executive officer or director nominee, or an immediate family member of any such person; or (ii) is known by us to be the beneficial owner of more than 5% of our common stock, or an immediate family member of such person.

Prior to entering into a potential Related Party Transaction, the Related Party (or the person whose immediate family member is the Related Party) or any member of management aware of the transaction must provide notice of the facts and circumstances of the proposed transaction to our General Counsel, Chief Financial Officer or Chief Accounting Officer, who will assess whether the proposed transaction is subject to the Policy. If it is determined that the proposed transaction is a Related Party Transaction, it is submitted to the Audit Committee for consideration at its next meeting. If it is not practicable or desirable to wait until the next Audit Committee meeting, the transaction may be submitted to the Chair of the Audit Committee for consideration (with any action taken by the Chair reported to the Audit Committee at its next regular meeting).

When considering a proposed Related Party Transaction, the Audit Committee reviews all of the relevant available facts and circumstances, including:

• the benefits of the transaction to the Company;

• any impact on a director's independence;

• the availability of other sellers or purchasers of comparable products or services;

• the terms of the transaction;

• whether the transaction is on terms comparable to those obtainable in an arm's-length transaction with an unrelated party; and

• the extent of the Related Party's interest in the transaction.

---

The Audit Committee will approve a Related Party Transaction if it determines that the transaction is in, or is not inconsistent with, the best interests of the Company and our stockholders. No member of the Audit Committee may participate in the consideration or approval of a transaction as to which he or she or any member of his or her immediate family is the Related Party, but may participate in the discussion of the transaction at the Audit Committee meeting if requested by the Chair of the Audit Committee.

The Related Party Transaction Policy prohibits the Company from directly or indirectly extending credit to, arranging for the extension of credit for, or renewing an extension of credit, in each case in the form of a personal loan, to any director or executive officer of the Company, except in the case of a trade receivable relating to work performed by the Company for the director or executive officer or an affiliate thereof in the ordinary course of the Company's business on terms comparable to those that could be obtained in an arm's length transaction with an unrelated party.

If a director or a member of management becomes aware of a Related Party Transaction that has not been approved by the Audit Committee, he or she must promptly notify our General Counsel, Chief Financial Officer or Chief Accounting Officer. If the transaction is pending or ongoing, it is submitted to the Audit Committee for review, and the Audit Committee will consider the relevant facts and circumstances and evaluate all options, including ratification, amendment or termination of the transaction. If the transaction is completed, the Audit Committee will determine if rescission of the transaction and/or disciplinary action is appropriate.

All of the transactions described in this section were approved by the Audit Committee in accordance with the Policy.

If you and members of your household have multiple accounts holding shares of our common stock, you may have received a householding notification from your broker, bank or other nominee. Please contact that organization if you have questions or wish to opt in our opt out of householding.

**Solicitation of Proxies**

Our Board of Directors is soliciting your vote for the proposals being submitted at the Annual Meeting. Solicitation is being made by mail or electronically but could also be made by our directors, officers and select other employees telephonically, electronically or by other means of communication. The Company will bear the cost of soliciting proxies. Directors, officers and employees who assist in the solicitation will not be compensated for those services, but may be reimbursed for out-of-pocket expenses. We are requesting brokers, banks and other nominees to forward our proxy materials to beneficial owners and we will reimburse them for their reasonable out-of-pocket expenses.

This Proxy Statement contains certain forward-looking statements, including with respect to the housing and commercial construction market, industry conditions, our operations, our ESG related initiatives and performance, our business model, expansion of our footprint and end markets, our product diversification and our pursuit of value enhancing acquisitions. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. These statements are based on management's current expectations, beliefs, estimates and projections. These statements include matters that are not historical facts, are not guarantees and are subject to certain uncertainties and other factors, many of which are beyond our control.

Statements and Risk Factors Summary" for a description of the risks and uncertainties related to any forward-looking statements included herein. Our actual performance, including the development of any program or initiative, may differ materially in the future. Forward-looking and other statements in this Proxy Statement regarding our ESG and sustainability plans and goals are not an indication that these statements are material to investors or required to be disclosed in our filings with the SEC. Historical, current, and forward-looking ESG and sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future.

**Use of Non-GAAP Financial Measures**

This Proxy Statement uses financial measures not calculated in accordance with GAAP including "Adjusted EBITDA" and "Adjusted General and Administrative Expense as a Percentage of Revenue." The reasons for the use of these measures and reconciliations to the most directly comparable GAAP measure are set forth below.

These performance measures evaluate performance by adjusting EBITDA and General and Administrative Expense for certain income or expense items that are not considered part of our core operations. We believe that these measures assist both management and the CHC Committee in analyzing and benchmarking the performance and value of our business and the performance of our executive team. We use Adjusted EBITDA-based measures in determining the achievement of awards under our executive incentive compensation programs. We use Adjusted General and Administrative Expense as a Percentage of Revenue in determining the achievement of Component 2 of our Five Year Plan.

We believe the Adjusted EBITDA measure is useful to investors and to us as a measure of comparative operating performance from period to period, because it measures our changes in pricing decisions, cost controls and other factors that impact operating performance, and removes the effect of our capital structure (primarily interest expense), asset base (primarily depreciation and amortization), items outside our control (primarily income taxes) and volatility related to the timing and extent of other activities such as asset impairments and non-core income and expenses.

We believe that Adjusted General and Administrative Expense as a Percentage of Revenue is useful to investors and to us as a performance measure because it measures how efficiently our management team manages our overhead costs relative to our ability to generate revenue. A lower or declining percentage after adjusting for non-core expenses generally indicates improved operating leverage, which can drive higher margins and profitability over time.

Accordingly, we believe that these measures are useful for comparing general operating performance from period to period. Other companies may define Adjusted EBITDA or Adjusted General and Administrative Expense as a Percentage of Revenue differently and, as a result, our measures may not be directly comparable to measures of other companies.

**Meeting and Voting Information**

Certain of the topics below refer to "stockholders of record" or "beneficial owners." If your shares were registered directly in your name with our transfer agent on the record date, then you are a "stockholder of record" with respect to those shares. If your shares were held in an account at a brokerage firm, bank or other nominee on the record date, then you are a "beneficial owner" of those shares.

**Attending the Annual Meeting**

Our Annual Meeting is conducted virtually by a live audio webcast in lieu of an in-person meeting. This format promotes stockholder participation by enabling stockholders to conveniently attend from any location. The virtual format results in cost savings to the Company and stockholders and is designed to enhance stockholder access and participation. You will be afforded the same rights and opportunities to participate in the virtual meeting as you would at an in-person meeting. You may attend and participate in the Annual Meeting in the following ways:

**Stockholders of Record.** You can listen to the Annual Meeting, submit questions and vote by going to https://meetnow.global/MQFXVJC, clicking on "Join Meeting Now" and entering under the stockholder tab the 15-digit control number found in your proxy materials.

**Beneficial Owners.** You may participate in the Annual Meeting in one of two ways:

• If you wish to submit questions or vote during the Annual Meeting (rather than instructing your brokerage firm, bank or other nominee how to vote your shares), you must register in advance by providing our transfer agent, Computershare Trust Company, N.A. ("Computershare") with your name, email address and a copy of a legal proxy from your brokerage firm, bank or other nominee reflecting your beneficial ownership. Registration requests must be in writing and mailed to Computershare Investor Services, Installed Building Products, Inc. – Legal Proxy, P.O. Box 43001, Providence, Rhode Island 02940-3001. Alternatively, you may forward a copy of the email from your broker granting you a legal proxy or forward an image of your legal proxy to legalproxy@computershare.com. Requests must be labeled "Legal Proxy" and be received no later than 5:00 p.m., Eastern Time, on May 14, 2026. You will receive an email from Computershare acknowledging your registration and providing you with a 15-digit control number. You can then listen to the Annual Meeting, submit questions and vote by going to https://meetnow.global/MQFXVJC, clicking on "Join Meeting Now" and entering under the stockholder tab your 15-digit control number.

• If you wish to listen to the Annual Meeting, but do not wish to submit questions or vote during the Annual Meeting, you may go to https://meetnow.global/MQFXVJC, click on "Join Meeting Now" and then click on "Guest."

The virtual meeting platform is fully supported across browsers (MS Edge, Firefox, Chrome and Safari) and devices (desktops, laptops, tablets and cell phones) running the most up-to-date version of applicable software and plugins. Internet Explorer is not a supported browser. Participants should ensure that they have a strong Wi-Fi connection. We encourage you to access the meeting prior to the start time.

**Who is Entitled to Vote; Quorum**

A list of our stockholders entitled to vote at the Annual Meeting will be available for examination by any stockholder during ordinary business hours at our principal executive offices at 495 South High Street, Suite 50, Columbus, Ohio 43215 for a period of ten days prior to the Annual Meeting. During the Annual Meeting, the list will be available at https://meetnow.global/MQFXVJC.

In order to carry out the business of the Annual Meeting, a quorum must be present. A quorum is present if holders of at least a majority of the outstanding shares entitled to vote are present or represented by proxy at the Annual Meeting. Abstentions and broker non-votes are counted as present for purposes of determining a quorum. On the record date, we had 26,938,333 shares entitled to vote, meaning that at least 13,469,168 shares must be present or represented by proxy to have a quorum. If a quorum is not present, the Annual Meeting may be adjourned from time to time until a quorum is present.

**How to Vote**

**Stockholders of Record.** You may vote in any of the following ways. Votes must be received no later than the closing of the polls at the Annual Meeting.

---

| | |
|:---|:---|
| **Online** | You may vote online at www.envisionreports.com/IBP, 24 hours a day, seven days a week. |

---

Voting online, by phone or at the Annual Meeting authorizes the persons named as proxies to vote as you direct in the same manner as if you had completed, signed, dated and returned a proxy card. If you vote online or by phone, or plan to vote during the Annual Meeting, do not return your proxy card(s). If you do not vote by any of the methods listed above, your shares will not be voted. If you submit a proxy but fail to provide voting instructions, your proxy will be voted in the manner recommended by the Board of Directors.

If you received more than one proxy card or Notice, your shares are registered in more than one name or are registered in multiple accounts. To make certain all of your shares are voted, please complete, sign, date and return each proxy card, or if you vote online, by telephone or at the Annual Meeting, vote once for each Notice you received.

**Beneficial Owners.** If you are a beneficial owner, the organization holding your account is the stockholder of record for purposes of participating in and voting at the Annual Meeting; however, you have the right to direct that organization how to vote the shares in your account by following the instructions provided by the organization. Alternatively, you may vote your shares directly at the Annual Meeting by obtaining a legal proxy from your brokerage firm, bank or other nominee and registering in advance to participate in the Annual Meeting. See *"Attending the Annual Meeting"* above. When you receive your registration confirmation, you may vote in any of the ways in which a stockholder of record may vote described above (except by mail).

The availability of online and telephone voting will depend on the voting procedures established by your broker, bank or other nominee. If you do not provide voting instructions to the organization holding your account, the organization may vote your shares on certain routine, or "discretionary," matters. The ratification of the appointment of our independent registered public accounting firm is a discretionary matter. On this proposal, the organization holding your account may either vote your shares in the absence of your instructions or may choose

not to vote your shares. The remaining proposals are not considered discretionary and cannot be voted without your instructions, which is called a "broker non-vote." In the case of a broker non-vote, your shares will not have any effect on the outcome of the proposal. If you registered in advance to participate in the Annual Meeting but do not vote your shares online, by phone or during the Annual Meeting, your shares will not be voted.

**Revoking your Proxy or Changing your Vote**

**Stockholders of Record.** You may revoke your proxy or change your vote at any time before the closing of the polls at the Annual Meeting by:

• signing and returning a new proxy card with a later date;

• submitting a later-dated vote online or by phone — only your latest vote will be counted;

• participating in the Annual Meeting and voting during the meeting; or

• delivering a written revocation to our Corporate Secretary at Installed Building Products, Inc., 495 South High Street, Suite 50, Columbus, Ohio 43215, which must be received no later than May 18, 2026.

Participating in the Annual Meeting without voting during the meeting will not cause a previously submitted vote to be revoked unless you specifically request that your prior vote be revoked.

**Beneficial Owners.** You should contact the broker, bank or other nominee holding your shares to obtain instructions for revoking or changing your vote. If you register in advance to participate in the Annual Meeting, you may change your vote by submitting a later-dated vote online, by phone or by voting during the meeting.
