The Notice of Annual Meeting and Proxy Statement on the following pages describe the matters to be presented at the meeting.

Our Annual Report for fiscal year 2021 accompanies this Proxy Statement.

Pursuant to U.S. Securities and Exchange Commission (the “SEC”) rules, we have elected to furnish proxy materials to our stockholders via the Internet instead of mailing printed copies of those materials to each stockholder. We believe this approach will reduce our costs and help the environment by reducing paper waste. If you received a “Stockholder Meeting Notice” by mail, which provides notice of Internet availability of proxy materials, you will not receive a printed copy of the proxy materials unless you request one. Instead, the Stockholder Meeting Notice will instruct you as to how you may access and review the proxy materials and cast your vote on the Internet. The Proxy Statement and the 2021 Annual Report are available online at www.edocumentview.com/HBP, however, a copy of the proxy materials will be delivered to any stockholder upon request at your address. If you wish to receive a hard copy of the proxy materials, you may call us at 314-216-2600 or send a written request to 555 Maryville University Dr., Suite 400, St. Louis, Missouri 63141, Attn: Corporate Secretary, or send an email to investorvote@computershare.com with “Proxy Materials Huttig Building Products, Inc.” in the subject line. Include your full name and address, plus the number located in the shaded bar on the reverse side of the Stockholder Meeting Notice, and state that you want to receive a paper copy of the proxy materials. You can also request an email copy. If you request an email copy, you will receive an email with a link to the current meeting materials.

Please note that you will be required to wear a mask to attend the meeting. Further, we ask that you practice social distancing during the meeting and follow any of our other required safety protocol. If you are experiencing any of the COVID-19 symptoms or you suspect or believe you have COVID-19 or were exposed to COVID-19 in the days leading up to the meeting, please do not attend the meeting.

It is important that your shares be represented at the meeting regardless of the size of your holdings. If you are unable to attend in person, we urge you to participate by voting your shares by proxy through one of the methods mentioned above.

Sincerely,

Jon P. Vrabely

PROXY STATEMENT

ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON TUESDAY, MAY 10, 2022

The Board of Directors of Huttig Building Products, Inc. (“Huttig” or the “Company”) is soliciting the proxy for use at the annual meeting of stockholders (the “Annual Meeting”) to be held at the Meadowbrooke/Forest Hills conference room of the St. Louis Marriott West, located at 660 Maryville Centre Drive, St. Louis, Missouri 63141 on Tuesday, May 10, 2022 at 8 a.m., local time, and at any adjournments or postponements thereof. Shares represented by the proxy, when properly voted prior to the Annual Meeting and not revoked, will be voted in accordance with the directions thereon.

If any other matter should be presented at the Annual Meeting upon which a vote may properly be taken, the shares represented by the proxy will be voted with respect thereto in accordance with the discretion of the person or persons holding such proxy.

The first date on which the Stockholder Meeting Notice is being sent and this Proxy Statement, the form of proxy, and the 2022 Annual Report is made available to the Company’s stockholders at www.edocumentview.com/HBP (and/or by mail, if requested) is on or about March 30, 2022.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS

FOR THE STOCKHOLDER MEETING TO BE HELD ON MAY 10, 2022

This Proxy Statement and the 2021 Annual Report to Stockholders are available at www.edocumentview.com/HBP.

How to Vote

Stockholders may vote by voting via the Internet or using the toll-free number listed on the Stockholder Meeting Notice. The “Stockholder Meeting Notice” is sent by mail and provides notice of Internet availability of proxy materials. The Internet and telephone voting procedures are designed to authenticate votes cast by use of a Personal Identification Number. Alternatively, stockholders may request a hard copy set of the Annual Report, Proxy Statement and proxy card and may vote by marking their proxy, dating and signing it and timely returning it to the Corporate Secretary. The procedures allow stockholders to appoint a proxy to vote their shares and to confirm that their instructions have been properly recorded. Specific instructions to be followed by any

1

stockholder of record interested in voting by telephone or the Internet are set forth on the Stockholder Meeting Notice. If your shares are held in the name of a bank or broker, follow the voting instructions on the form you receive from that firm. The availability of telephone or Internet voting will depend on that firm’s voting processes.

How to Revoke a Vote

Stockholders may revoke proxies at any time prior to the voting of the proxy by (a) providing written notice to the Company, (b) submitting a new later-dated proxy via the Internet, telephone or by mail, or (c) voting in person at the Annual Meeting.

Special Voting Rules for Participants in Huttig’s 401(k) Plan

If you participate in the Huttig Building Products, Inc. Savings and Profit Sharing Plan (the “401(k) Plan”), you will receive one proxy with respect to all of your shares of Huttig stock registered in the same name. If your accounts are not registered in the same name, you will receive a separate proxy with respect to each registered name for which you have an account. Shares of Huttig common stock (“Common Stock”) held in the 401(k) Plan will be voted by The Prudential Investment Company of America, as trustee of the 401(k) Plan, as directed by 401(k) Plan participants.

Participants in the 401(k) Plan should indicate their voting instructions for each action to be taken at the Annual Meeting on the Huttig proxy. All voting instructions from the 401(k) Plan participants will be kept confidential. If a participant fails to vote, the Huttig shares allocated to such participant will be voted in accordance with the Board’s recommendation.

Outstanding Shares and Required Votes

As of the close of business on March 14, 2022, the record date for determining stockholders entitled to vote at the Annual Meeting, the Company had issued and outstanding 27,328,538 shares of Common Stock. Each share of Common Stock is entitled to one vote on each matter to be voted on at the Annual Meeting. At the Annual Meeting, a quorum will be present if at least a majority of the total number of outstanding shares of our Common Stock are present, either in person or represented by proxy.

Directors will be elected by a plurality of the votes cast by holders of shares of Common Stock present in person or represented by proxy and entitled to vote at the Annual Meeting. Votes may be cast in favor of a director nominee or withheld, and the nominees receiving the highest number of favorable votes will be elected as directors of the Company. Because at this year’s Annual Meeting, there are as many nominees (three) as there are directors to be elected (three), a director nominee is assured of being elected if he or she receives any “For” votes, regardless of how many withheld votes are cast for that director.

The advisory approval of the compensation paid by the Company to its named executive officers and the ratification of the appointment of KPMG LLP each require the affirmative vote of a majority of the votes cast by the holders of shares of Common Stock present in person or represented by proxy and entitled to vote at the Annual Meeting.

Abstentions and broker non-votes are counted as present or represented for purposes of determining whether a quorum is present at the meeting. Stockholders may abstain from voting on any or all proposals expected to be brought before the meeting except for the election of directors. Abstentions do not count as votes cast for or against a matter and, therefore, will not affect the outcome of the voting with respect to such matters at the meeting.

A broker non-vote occurs with respect to a particular matter when a broker returns a proxy card but does not vote on the matter because the broker does not have the discretionary authority to do so in the absence of voting

2

instructions from the beneficial owner. Brokers have discretionary authority to vote on Item 3, the ratification of the appointment of KPMG LLP; however, brokers do not have discretionary authority to vote on the election of directors or on any of the other items to be considered at the Annual Meeting if the broker does not receive voting instructions from you. Broker non-votes do not count as votes cast for or against a matter or as shares “entitled to vote,” and therefore will not affect the outcome of the voting at the Annual Meeting.

Availability and Householding of Materials

Pursuant to the SEC rules, we have elected to again furnish proxy materials to our stockholders via the Internet instead of mailing printed copies of those materials to each stockholder. We believe this approach will reduce our costs and help the environment by reducing paper waste. If you received a “Stockholder Meeting Notice” by mail, which provides notice of Internet availability of proxy materials, you will not receive a printed copy of the proxy materials unless you request one. Instead, the Stockholder Meeting Notice will instruct you as to how you may access and review the proxy materials and cast your vote on the Internet. The Proxy Statement and the 2021 Annual Report are available online at www.edocumentview.com/HBP, however, a copy of the Proxy Statement and 2021 Annual Report will be delivered to any stockholder upon request at your address. If you wish to receive a hard copy of this Proxy Statement or the 2021 Annual Report, you may call us at 314-216-2600 or send a written request to 555 Maryville University Dr., Suite 400, St. Louis, Missouri 63141, Attn: Corporate Secretary, or send an email to investorvote@computershare.com with “Proxy Materials Huttig Building Products, Inc.” in the subject line. Include your full name and address, plus the number located in the shaded bar on the reverse side of the Stockholder Meeting Notice, and state that you want to receive a paper copy of the proxy materials. You can also request an email copy. If you request an email copy, you will receive an email with a link to the current meeting materials. Stockholders sharing an address who now receive multiple copies of this Proxy Statement or the 2021 Annual Report may request delivery of a single copy also by calling us at the number or writing to us at the address listed above or sending an email as provided above. By requesting email copies or by requesting a single copy for multiple stockholders sharing the same address, you can also help the environment.

ITEM 1 — ELECTION OF DIRECTORS

The Board of Directors of the Company (the “Board” or “Board of Directors”) is currently comprised of seven members and is divided into three classes, with each class holding office for staggered three-year terms. At the Annual Meeting, Jon P. Vrabely, Patrick L. Larmon, and James F. Hibberd, if elected, will hold office until the 2025 Annual Meeting of stockholders. If properly voted prior to the Annual Meeting, and not revoked, the enclosed proxy will be voted for the election of these directors unless a stockholder indicates that a vote should be withheld with respect to any or all of such nominees. The election of each nominee has been recommended by the Board of Directors. Each of the nominees has consented to being named in this Proxy Statement and has indicated his willingness to serve if elected. If any of the nominees shall, prior to the meeting, become unavailable for election as a director, the persons named in the accompanying form of proxy will vote for such replacement nominee, if any, as may be recommended by the Board of Directors.

5

director nominee or withheld, and the nominees receiving the highest number of favorable votes will be elected as directors of the Company. Because at this year’s Annual Meeting, there are as many nominees (three) as there are directors to be elected (three), a director nominee is assured of being elected if he or she receives any “For” votes, regardless of how many withheld votes are cast for that director.

BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD OF DIRECTORS

Board of Directors

The Board of Directors is currently comprised of seven directors. The Board of Directors held 6 meetings and 8 regular Committee meetings in 2021. For their respective terms on the Board, each director attended all fiscal year 2021 meetings of the Board and each Committee on which he or she served. The Company’s directors are encouraged to attend the Annual Meeting. All of the Company’s directors attended the 2021 Annual Meeting of Stockholders.

Director Independence

On an annual basis, and at other appropriate times when a change in circumstances could potentially impact the independence or effectiveness of one or more of the directors, the Board of Directors evaluates the independence of the directors and determines if each director qualifies as an “independent director” as defined under the listing requirements of NASDAQ on which the Company’s Common Stock is listed. After carefully considering all relevant facts and circumstances, the Board of Directors has affirmatively determined that six of the Company’s seven directors, Ms. Hoagland and Messrs. Glass, Hibberd, Larmon, Matheney and Tanner, are independent in accordance with the standards established by NASDAQ. The Board has made a determination as to each independent director that no relationship exists which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Mr. Vrabely does not meet the NASDAQ independence standards for a director because he is an executive officer of the Company.

The Board of Directors has also affirmatively determined that:

Corporate Governance

The Company has adopted Corporate Governance Guidelines, as well as a Code of Business Conduct and Ethics applicable to all directors, officers and employees. The Corporate Governance Guidelines and the Code of Business Conduct and Ethics are available on the Company’s website at www.huttig.com. Information on, or accessible through, the Company’s website is not a part of, and is not incorporated into, this Proxy Statement. The Company intends to post on its website any amendments to, or waivers from, its Code of Business Conduct and Ethics within four business days of such amendment or waiver.

The Nominating and Governance Committee is responsible for reviewing the Corporate Governance Guidelines from time to time and reporting and making recommendations to the Board concerning corporate governance matters. Each year, the Nominating and Governance Committee reviews the Company’s corporate governance practices to ensure that (a) they comply with applicable laws, (b) they continue to reflect what the Nominating and Governance Committee believes are best practices, and (c) they promote the best interests of the Company and its stockholders. Although the Company does not currently have a policy which prohibits the hedging of Company securities by its directors and employees, there are no hedging arrangements currently in place by our directors or executive officers.

6

Board Leadership Structure

The Board has chosen to separate the positions of Chairperson of the Board and Chief Executive Officer at this time. Mr. Delbert H. Tanner, a non-employee independent director, serves as Chairperson, and Mr. Jon P. Vrabely serves as the President and Chief Executive Officer. Separating the Chair position and the Chief Executive Officer position allows the Chief Executive Officer to focus on setting the strategic direction of the Company and on our day-to-day business, and allows the Chairperson to lead the Board in its fundamental role of providing advice to and independent oversight of management. While the Company’s Amended and Restated By-laws (“bylaws”) and Corporate Governance Guidelines do not require that our Chairperson and Chief Executive Officer positions be separate, the Board believes that having separate positions and having an independent outside director serve as Chairperson is the appropriate leadership structure for the Company at this time. The Board retains the discretion to assess whether the positions should be combined or separated at any given time based upon its evaluation of, among other things, the composition of the Board and the circumstances facing the Company.

Board Role in Risk Oversight

The Board believes that an important part of its responsibilities is to review the Company’s assessment of the major risks the Company faces and its policies for monitoring and controlling these risks. The Audit Committee has specific responsibility for oversight of risks associated with financial accounting and audits, as well as internal control over financial reporting. Management regularly reports to the Audit Committee on the Company’s risk assessment and management policies, the Company’s major financial and operational risk exposure, including, cybersecurity risk, and the steps taken by management to monitor and mitigate such exposure. The Management Organization and Compensation Committee oversees the risks relating to the Company’s compensation policies and practices, as well as management development and leadership succession. It believes it has allocated executive compensation among base salary and short- and long-term compensation target opportunities in such a way as to not encourage excessive risk-taking. The Board, as a whole, examines specific business risks as part of its regular strategic reviews. In addition, management periodically reviews with the Board matters of particular importance or concern, including any significant areas of risk that warrant Board attention. In particular, the Board has taken an active role in oversight related to the COVID-19 pandemic. The Board receives regular briefings about the pandemic and the potential risks it poses to the Company, its operations and its financial condition. The Board has used this information to guide and oversee the implementation of the Company’s response to COVID-19.

Board Committees

The Board of Directors has four standing Committees: (1) Executive, (2) Audit, (3) Management Organization and Compensation, and (4) Nominating and Governance. The Board may from time to time designate one or more ad hoc committees with respect to certain matters. The Executive Committee meets when a quorum of the full Board of Directors cannot be readily obtained. In 2021, the Executive Committee did not hold any meetings.

Except for the Executive Committee, which operates under the authority set forth in our bylaws, each of the standing Committees operates under a written charter adopted by the Board of Directors. All of the Committee charters are available on the Company’s website at www.huttig.com. Information on, or accessible through, the Company’s website is not a part of, and is not incorporated into, this Proxy Statement.

The current memberships of the four standing committees of the Board of Directors follow:

Audit Committee

The Audit Committee assists the Board in fulfilling the Board’s oversight responsibility with respect to the integrity of the Company’s financial statements, the qualification and independence of the Company’s independent auditors, the performance of the Company’s internal audit function and its internal auditors, the Company’s compliance with legal and regulatory requirements and the Company’s risk assessment and risk management policies. The Audit Committee assesses financial, credit and liquidity, legal and regulatory risk, cybersecurity threats and operational risks and reviews management’s processes and procedures to manage and mitigate such risks. The Audit Committee regularly informs the Board through committee reports about such risks.

The Audit Committee has the sole authority to select, evaluate and, where appropriate, replace the independent auditors. The Audit Committee meets periodically with representatives from the Company’s internal auditors and independent auditors separate from management. The Audit Committee is also responsible for reviewing compliance with the Company’s Code of Business Conduct and Ethics and for administering and enforcing the Company’s accounting and auditing compliance procedures adopted in accordance with Section 301 of the Sarbanes-Oxley Act of 2002. In discharging its oversight responsibility as to the audit process, the Audit Committee obtained from the independent auditors a formal written statement confirming the absence of any relationships between the auditors and the Company that might bear on the auditors’ independence, consistent with applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence. The Audit Committee discussed with the independent auditors any activities that may impact their objectivity and independence, including fees for non-audit services, and satisfied itself as to the auditors’ independence. The Audit Committee also received a report on the quality control procedures of the independent auditors, as well as the most recent peer review conducted under guidelines of the American Institute of Certified Public Accountants. The Audit Committee also discussed with management, the internal auditors and the independent auditors the quality and adequacy of the Company’s internal controls and the internal audit function’s organization, responsibilities, budget and staffing, and results of the internal audit examinations. The Audit Committee reviewed with the independent auditors and the internal auditors their audit plan and audit scope and the independent auditors’ examination of the financial statements.

The Board of Directors has determined that Messrs. Matheney and Larmon meet the requirements of an “audit committee financial expert” as defined in regulations of the SEC. During 2021, the Audit Committee held 4 meetings.

The report of the Audit Committee is included under “Report of the Audit Committee” in this Proxy Statement.

Management Organization and Compensation Committee

The Management Organization and Compensation Committee (the “Compensation Committee”) oversees the Company’s compensation plans and practices, including its executive compensation plans and director

8

compensation plans, reviews and evaluates the performance of the Chief Executive Officer, reviews with the Chief Executive Officer his evaluation of the performance of other members of senior management, administers the Company’s restricted stock and other stock-based compensation plans and programs, reviews management development and succession planning policies and produces the annual report on executive compensation for inclusion in the Company’s annual proxy statement. During 2021, the Compensation Committee held 3 meetings.

Nominating and Governance Committee

The Nominating and Governance Committee’s duties include assisting the Board by identifying individuals qualified to become members of the Board, recommending to the Board the director nominees for election at the next annual meeting of stockholders of the Company, advising the Board with respect to Board composition and procedures, advising the Board with respect to corporate governance principles and overseeing the evaluation of the Board. During 2021, the Nominating and Governance Committee held one meeting.

Director Qualifications and Nominating Procedures

The Company’s Corporate Governance Guidelines provide that the Board should generally have between seven and eleven directors, a substantial majority of whom must qualify as independent directors as defined under the listing standards of NASDAQ. The Corporate Governance Guidelines provide that a director who serves as the Company’s Chief Executive Officer should not serve on more than two other public company boards, other directors should not serve on more than four other public company boards and members of the Audit Committee should not serve on more than two other public company audit committees.

The Board seeks to identify and recruit the best available director candidates to sustain and enhance the composition of the Board with the appropriate balance of knowledge, experience, skills, expertise and diversity. Characteristics required for service on the Company’s Board include integrity, an understanding of the workings of large business organizations such as the Company, senior level executive experience, the ability to make independent, analytical judgments, the ability to be an effective communicator, and the ability and willingness to devote the time and effort to be an effective and contributing member of the Board. The Board also reviews diversity of experience, expertise and perspectives when considering potential candidates. The Board will consider potential director candidates proposed by other members of the Board and management and those potential director candidates properly proposed by our stockholders. From time to time, the Nominating and Governance Committee may retain search firms or other advisors to assist it in recruiting the best available director candidates for the Company.

Although the Company does not have a formal written diversity policy for the Board, the Board determines the most appropriate mix of characteristics, skills and experiences for the Board as a whole to possess at any given time, with the objective of having a Board with adequately diverse backgrounds and experiences in light of the circumstances existing at that time. The Board evaluates each individual in the context of that individual’s potential contribution to the Board as a whole with the objective of recommending a collective group that can best promote the success of the Company’s business, represent stockholder interests through the exercise of sound judgment and allow the Board as a whole to benefit from the group’s varying backgrounds and experiences. The Board applies the same criteria to all candidates that it considers, including any candidates properly submitted by our stockholders.

As noted, the Board values diversity. The NASDAQ diversity matrix is set forth below as required under the listing requirements of NASDAQ.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee has reviewed and discussed with management the financial statements for fiscal year ended December 31, 2021 audited by KPMG LLP, the Company’s independent registered public accounting firm. The Audit Committee has discussed with KPMG LLP various matters related to the financial statements, including those matters required to be discussed by Public Company Accounting Oversight Board Auditing Standard No. 1301, Communications with Audit Committees, and the SEC. The Audit Committee has also received the written disclosures and the letter from KPMG LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and has discussed with KPMG LLP its independence. Management is responsible for the preparation, presentation and integrity of the Company’s financial statements, the Company’s internal controls and financial reporting process and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The Company’s independent auditors are responsible for performing an independent audit of the Company’s financial statements, expressing an opinion as to their conformity with generally accepted accounting principles. Based upon such review and discussions, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 for filing with the SEC.

Other than Mr. Matheney, who is a practicing certified public accountant, the members of the Audit Committee are not professionally engaged in the practice of auditing or accounting. The members of the Audit Committee are not, and do not represent themselves to be, performing the functions of auditors or accountants. Members of the Audit Committee may rely without independent verification on the information provided to them and on representations made by management and the independent auditors. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions referred to above do not assure that the audit of the Company’s financial statements has been carried out in accordance with generally accepted auditing standards, that the financial statements are presented in accordance with generally accepted accounting principles, or that the Company’s auditors are in fact “independent.”

This report is not to be deemed “soliciting material” or deemed to be “filed” with the SEC or subject to Regulation 14A of the Securities Exchange Act of 1934, as amended, or to the liabilities of Section 18 of the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically requests that this report be treated as “soliciting material” or specifically incorporates it by reference into a document filed with the SEC.

EXECUTIVE COMPENSATION

We are currently considered a “smaller reporting company” for purposes of the SEC’s executive compensation and other disclosure rules. In accordance with such rules, we are required to provide a Summary Compensation Table, an Outstanding Equity Awards at Fiscal Year-End Table and certain limited narrative disclosures. Further, our reporting obligations generally extend only to the individuals who served as our Chief Executive Officer and our two other most highly compensated executive officers during fiscal year 2021.

Summary Compensation Table

Shown below is information concerning the total compensation paid to and compensatory awards received by the named executive officers of the Company during each of the relevant years.

18

Additional Narrative Disclosures

Executive compensation is generally comprised of the following components: base salary; annual incentive compensation; long-term incentive awards; defined contribution plan benefits; and perquisites and other personal benefits.

Each of these components represents a portion of each executive officer’s total compensation package, although participation in the defined contribution plan is at the option of the executive officer. Our policy for allocating between short-term and long-term compensation seeks to ensure adequate base compensation to attract and retain qualified personnel, while providing incentives to maximize long-term value for the Company and its stockholders. We do not maintain a pre-established policy or formula for the allocation between cash and non-cash or short-term and long-term compensation.

In setting executive compensation for 2021, the Compensation Committee considered the results of the Company’s “say-on-pay” proposal at the 2021 annual meeting of stockholders, which was approved by approximately 94.9% of the votes cast by the Company’s stockholders.

Base Salaries

The annual base salary for our named executive officers as of December 31, 2021 was as follows:

2021 Annual Incentive Compensation

In 2021, each named executive officer was eligible to receive an annual cash bonus under the EIC Plan. The annual cash bonuses granted under the EIC Plan are designed to link executives’ pay to performance and align their interests with our stockholders by rewarding the executive based on Company performance achievement. For 2021, the Board primarily used the percentage of improvement in the EVA performance measure to determine Company performance, among other factors. EVA is a measurement of the amount by which the Company’s after-tax profits, after certain adjustments, exceed the cost of capital employed by the Company. The Company determines the percentage of absolute EVA generated for 2021 and the percentage of improvement in EVA from 2020 to 2021 to determine the annual cash bonus pool. In evaluating EVA, the Compensation Committee used a weighted average cost of capital of 3.87%.

The Compensation Committee determined that the bonus pool would be 6% of the 2021 EVA of $62,045,000, or $3,723,000 plus 10% of the $50,008,000 improvement in EVA from 2020 to 2021 or $5,008,000. This resulted in a total incentive cash bonus pool for 2021 of $8,731,000. The Compensation Committee reviewed the executives’ performance and the achievements of the Company for 2021.

Mr. Vrabely’s employment agreement provides that his targeted annual bonus incentive is not less than 100% of his current base salary. For the other named executive officers, the payout percentages are established using the respective individual’s annual STI target as a percent of the total STI target for all participants. Per

19

Mr. Furio’s employment agreement, he is entitled to a target short-term cash incentive award target of 87.5% of his base salary. Mr. Keipp’s target is 75% of his base salary. The Compensation Committee considered Mr. Vrabely’s recommendations, the scope of each executive officer’s duties, prior year awards, performance in areas of leadership, and completion of key projects. The Compensation Committee considered the Company’s record financial results for 2021. Mr. Keipp continued to successfully implement cost containment measures to improve the Company’s operating leverage as compared to prior years. Mr. Furio managed supply chain disruption and the impact to vendor and customer relationships during the pandemic. Mr. Vrabely continued to manage and react quickly to market changes throughout 2021 and led the Company’s strategic review process and execution against the Company’s three to five year business plan.

The following table lists the annual cash bonus awards allocated to the named executive officers under the EIC Plan for 2021. These amounts were paid in March 2022.

Long Term Incentive Awards

The Company considers its long-term incentive awards program a key employee retention tool and a way to better align the interests of our named executive officers with those of our stockholders. In making decisions regarding the size of long-term incentive awards for executive officers, the Compensation Committee considers factors such as each individual’s performance and responsibilities and Company performance.

Mr. Vrabely’s employment agreement provides that on an annual basis, he is eligible to receive a long-term incentive award with an aggregate target opportunity of at least 100% of his base salary, which award may be cash-based or stock-based and subject to time-vesting or performance-vesting as the Board shall determine in its sole discretion. In 2021, Mr. Vrabely received a time-vesting restricted stock award of 48,840 shares (as shown in the table below) and a cash long-term performance based incentive award (the “Cash LTI”) based on the performance of the Company. Mr. Furio’s employment agreement provides for a target long-term incentive award equal to 75% of his base salary. For 2021, Mr. Furio received a restricted stock award of 75,000 shares. For Mr. Keipp, the Company considers factors such as the individual’s performance and responsibilities. For 2021, Mr. Keipp received a restricted stock award of 40,000 shares. Each of the 2021 restricted stock awards vest ratably over three years assuming the named executive officer’s continued employment or vest immediately in the event of death, permanent disability, or a change in control of the Company, and, for Messrs. Furio and Vrabely, per the terms of their respective employment agreements, the 2021 restricted stock awards also vest immediately upon termination of employment by the Company without cause (or by the named executive officer for good reason).

The following table reflects the number of shares of restricted stock granted to our named executive officers in 2021:

Long Term Incentive Compensation

For the 2021 Cash LTI award granted to Mr. Vrabely, the Compensation Committee set two equally weighted goals with a payout ranging from 0% to 200% of target for each goal to be earned over a three-year

20

performance period (2021-2023). The first goal is based on Huttig-Grip fastener sales as compared to 2020 baseline results, and the second goal is based on pre-finished exterior door sales as compared to 2020 baseline results.

For each goal, the Compensation Committee set annual “milestone” goals for 2021, 2022 and 2023 that could result in a partial payment of the 2021 Cash LTI award at the end of each year. The 2021 Cash LTI award had a 2021 milestone goal of 16.7% growth in fastener warehouse sales and 16.8% growth in pre-finished exterior door sales; the Company achieved both milestones for 2021. As a result, Mr. Vrabely earned cash compensation of $143,334.

For the 2021 LTI, the following summarizes the milestone goals for 2021, 2022 and 2023:

The 2020 Cash LTI award that was previously granted to Mr. Vrabely had a 2021 milestone goal of $30,000,000 in Adjusted EBITDA and 10.2% for the EBITDA return on average working capital for 2021. The Company achieved both milestone goals for 2021 under the 2020 Cash LTI award, and Mr. Vrabely received cash compensation of $166,666.

The 2019 Cash LTI award that was previously granted to Mr. Vrabely had a 2021 milestone goal of $35,000,000 in Adjusted EBITDA and 18% for the EBITDA return on average working capital for 2021, with a maximum goal of $44,000,000 in Adjusted EBITDA and 20% for EBITDA return on working capital for 2021. Mr. Vrabely exceeded the maximum goal. The Company achieved both milestones for 2021 under the 2019 Cash LTI award, and Mr. Vrabely received cash compensation of $575,000.

Retirement Plans

The Company provides retirement benefits to the named executive officers under the terms of its tax-qualified 401(k) defined contribution plan. The Company provides matching contributions to employees who participate in the 401(k) plan. For every pre-tax dollar contributed to the 401(k) plan, the Company made matching contributions of $0.50 for every dollar contributed to the plan, up to a total of 6% of the employee’s total eligible deferral amount. However, the Company suspended the matching contribution program in March 2020 due to cost containment measures in connection with the COVID-19 pandemic. The match was reinstated on April 26, 2021. The named executive officers participate in the 401(k) plan on substantially the same terms as our other participating employees.

In 2016, as required by Mr. Vrabely’s employment agreement, the Company established the DC Plan in which only Mr. Vrabely participates. Under the DC Plan, and consistent with the terms of Mr. Vrabely’s employment agreement, the Company makes an annual contribution, with the amount to be determined by the Board in its discretion based on Company and individual performance. No elective deferrals by Mr. Vrabely are permitted. The Company contributions under the DC Plan do not become vested until January 1, 2023, subject to Mr. Vrabely’s continued employment with the Company through such date, or receive accelerated vesting in the event of his death, permanent disability, termination of employment by the Company without cause or termination of employment by Mr. Vrabely for good reason, or in the event that the DC Plan is terminated by the Company following a change of control. The Compensation Committee believes that these vesting provisions will further encourage Mr. Vrabely’s retention through the vesting date.

For 2021, the Company contributed $150,000 to Mr. Vrabely’s account under the DC Plan. The Compensation Committee considered the Company and individual performance and the recommendation from the Compensation Committee’s compensation consultant when making the 2021 contribution.

21

During the deferral period, balances in Mr. Vrabely’s account under the DC Plan will be adjusted with deemed investment returns based on Mr. Vrabely’s investment choices, all of which are based on market rates of return. Vested balances are payable from the DC Plan in a lump sum following Mr. Vrabely’s termination of employment or his earlier disability or death. Amounts contributed to the DC Plan will be included as compensation in the Summary Compensation Table in the year of vesting.

Perquisites and Other Personal Benefits

The Company provides the named executive officers with perquisites and other personal benefits that the Company believes are reasonable and consistent with its overall compensation program to better enable the Company to attract and retain superior employees for key positions. The Compensation Committee periodically reviews the levels of perquisites and other personal benefits provided to the named executive officers. Mr. Vrabely receives additional supplemental life and long-term disability insurance with benefits of three times his base salary upon death and providing supplemental income in the event of his disability. Mr. Furio is provided with a car allowance, and Mr. Vrabely has the use of a Company car.

Costs of the perquisites and personal benefits described above for the named executive officers that meet the threshold established by applicable SEC rules are included in the preceding Summary Compensation Table under the “All Other Compensation” column.

Employment and Change in Control Agreements

Employment Agreements with Messrs. Vrabely and Furio. The Company maintains an employment agreement with each of Messrs. Vrabely and Furio, which provides for certain payments in connection with a qualifying termination of employment.

Without Cause Payments and Benefits

In the case of a termination of employment by the Company without “Cause” (as defined in the applicable employment agreement), including a decision of the Company to not renew the term of the employment agreement other than for Cause, Mr. Vrabely would receive (i) all benefits described below under “Death or Disability” except for the pro-rated annual bonus, which is an amount equal to a pro-rated annual bonus based on the Company’s actual performance through the termination date, subject to any applicable performance formula for the year of termination, (ii) a cash severance payment equal to two times the sum of his base salary plus the average bonus (as defined in the applicable employment agreement) (payable in periodic installments over 24 months), and (iii) two years of COBRA premiums based on the terms of Company’s group health plan and the executive’s coverage under such plan.

In the case of a termination of employment by the Company without “Cause” (as defined in the applicable employment agreement), including a decision of the Company to not renew the term of the employment agreement other than for Cause, under his employment agreement, Mr. Furio would receive (i) an amount equal to one times the executive’s then current base salary, (ii) an amount equal to 12 months of COBRA premiums based on the terms of the Company’s group health plan and the executive’s coverage under such plan, and (iii) a pro rata annual bonus for the year of termination, based on actual performance results for the year.

Death or Disability Payments and Benefits

Under Mr. Vrabely’s employment agreement, upon his termination of employment due to death or disability, he will receive a pro-rated annual bonus calculated by multiplying the average bonus paid or payable to him for the three fiscal years prior to the year of termination by a fraction, the numerator of which is the number of days in the then-current fiscal year through the termination date, and the denominator of which is 365. Additionally, all performance-based long term incentive (“LTI”) awards will become vested on termination, and

22

Mr. Vrabely will be paid for the full projected three-year performance of the outstanding LTI awards based on the actual performance through the date of termination instead of calculating the outstanding LTI awards on a pro rata basis during the year of termination; and Mr. Vrabely’s unvested account balance under the DC Plan shall vest.

Mr. Furio is not entitled to receive any additional payments or benefits upon his termination of employment due to death or disability unless within the applicable change in control protected period.

Change in Control Termination Payments and Benefits

Under Mr. Vrabely’s employment agreement, in case of termination of employment due to death or disability within the applicable change in control protected period, Mr. Vrabely will receive the same benefits as described above under his employment agreement for termination due to death or disability, while Mr. Furio will be entitled to a pro-rated bonus based on his average bonus for the prior two years.

Under the employment agreements, in case of termination of employment by the Company without “Cause” or by the executive for “Good Reason” (as defined in the applicable employment agreement) within the applicable change in control protected period, each of Messrs. Vrabely and Furio will receive:

For all performance-based Cash LTI awards that will become vested on termination, Mr. Vrabely will be paid for the full projected three-year performance of the outstanding LTI awards based on the actual performance through the date of termination instead of calculating the outstanding LTI awards on a pro rata basis during the year of termination.

Change in Control Agreement with Mr. Keipp. The Company has entered into a change in control agreement with Mr. Keipp. The change in control agreement does not become effective until the occurrence of a change in control and generally only provides benefits upon an involuntary termination or constructive termination that occurs within three years following such change in control.

Under Mr. Keipp’s change in control agreement, in case of termination of employment by the Company without “Cause” or by the executive for “Good Reason” within the three-year change in control protected period, Mr. Keipp will receive:

Mr. Keipp’s change in control agreement also provides, in the case of a termination of employment due to death or disability within the three-year change in control protected period, Mr. Keipp will receive a pro-rated bonus based on his average bonus for the prior three years.

23

All payments described above are generally conditioned on the applicable named executive officer signing a release of all claims in favor of the Company. There are no excise tax gross-ups provided under the employment agreements. Instead, if the Company’s tax counsel determines that any economic benefit or payment or distribution by the Company to the employee pursuant to the agreement is subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), the Company may reduce the aggregate payments due to the employee under the agreement and any other agreement, plan or program of the Company to an amount that is one dollar less than the maximum amount allowable without becoming subject to the excise tax. Payments under the arrangements described above are generally made (i) in equal monthly installments (24 in the case of Mr. Vrabely and 12 in the case of Mr. Furio) for a termination of employment without Cause prior to the applicable change in control protected period, or (ii) in a lump sum payment for a termination of employment without Cause or for Good Reason within the applicable change in control protected period or, if applicable, due to death or disability; provided that, for Mr. Vrabely, amounts payable for a termination of employment without Cause or for Good Reason within the applicable change in control protected period may be paid in monthly installments over 36 months to the extent necessary to comply with Section 409A of the Code.

In addition, the employment agreements and change in control agreement generally prohibit each named executive officer from engaging in certain conduct during the term of employment and for one year following termination from employment with the Company, namely: (1) engaging in any business that is competitive with the Company, (2) soliciting for employment any current employee of the Company or any individual who had been employed by the Company in the one year prior thereto, (3) soliciting the business of the Company or doing business with any actual or prospective customer or supplier of the Company, and (4) taking any action which is intended, or would reasonably be expected, to harm the Company or its reputation or which would reasonably be expected to lead to unwanted or unfavorable publicity to the Company. The employment agreements and change of control agreement also generally prohibit the officer from disclosing any confidential information of the Company at any time.

Other Arrangements. Pursuant to the terms of the restricted stock awards held by our named executive officers, all unvested shares of restricted stock granted pursuant to such awards will vest in full upon (i) a termination of employment due to death or permanent disability, (ii) retirement at or after age 65, or (iii) a change in control of the Company; provided, Mr. Vrabely’s restricted stock awards also vest in full upon termination of employment without cause.

Accounting and Tax Considerations

The Compensation Committee generally considers the financial accounting implications of stock awards and other compensation to the Company’s executive officers in evaluating and establishing the Company’s compensation policies and practices. In addition, Section 162(m) of the Code, limits the deductibility of annual compensation paid to certain executive officers to $1 million per employee. The Compensation Committee believes that in establishing incentive compensation programs for our named executive officers, the potential deductibility of the compensation payable should be only one of several factors taken into consideration and not the sole governing factor. For that reason, the Compensation Committee may deem it appropriate to continue to provide one or more named executive officers with the opportunity to earn compensation that may be in excess of the amount deductible by reason of Section 162(m) or other provisions of the Code.

24

Outstanding Equity Awards at 2021 Fiscal Year-End

The following table sets forth certain information with respect to unvested shares of restricted stock held at December 31, 2021 by each of the named executive officers (there are no other outstanding equity awards held by our named executive officers):

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The Company’s Audit Committee charter requires that the Audit Committee, which is comprised entirely of independent directors, review all related party transactions and potential conflict of interest situations involving members of the Board of Directors or senior management. Current SEC rules define a related party transaction to include any transaction, arrangement or relationship in which the Company is a participant and the related party has a direct or indirect interest. Since January 1, 2021, the beginning of the Company’s last fiscal year, the Company has not had any related party transactions involving an amount in excess of the lesser of $120,000 and one percent of the average of the Company’s total assets at year-end for the last two completed fiscal years.

25

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee is comprised of Messrs. Glass, Hibberd, and Tanner and Ms. Hoagland. No member of the Compensation Committee is or has ever been an officer or employee of the Company, and no executive officer of the Company has served as a director or member of a compensation committee of another company of which any member of the Board of Directors is an executive officer.

PRINCIPAL ACCOUNTING FIRM SERVICES AND FEES

The following table sets forth the aggregate fees billed for the years ended December 31, 2021 and 2020 by KPMG LLP, the Company’s principal accounting firm during those years.

The Audit Committee has adopted a policy under which the independent auditors are prohibited from performing certain services in accordance with Section 202 of the Sarbanes-Oxley Act of 2002. The Audit Committee pre-approves all services to be provided by the independent auditors. The Audit Committee pre-approves the annual audit engagement terms and fees at the beginning of the year and pre-approves, if necessary, any changes in terms or fees resulting from changes in audit scope, Company structure or other matters. For services other than the annual audit engagement, if pre-approval by the full Audit Committee at a regularly scheduled meeting is not practical due to time limitations or otherwise, the Chairperson of the Audit Committee may pre-approve such services and shall report any such pre-approval decision to the Audit Committee at the next regularly scheduled meeting.

ITEM 2 — ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

We are asking our stockholders to provide advisory approval of the compensation of our named executive officers, as described in this Proxy Statement. While this vote is advisory, and not binding on the Company, it will provide information to us regarding stockholder sentiment about our core principles and objectives, which we will be able to consider when determining executive compensation in the future. Last year, approximately 94.9% of the votes cast in our advisory vote approved the compensation of our named executive officers.

Stockholders should review the compensation information set forth in this Proxy Statement, compensation tables, and related narratives appearing in this Proxy Statement for more information regarding the compensation of our named executive officers. As described in those sections, the primary objective of our executive compensation program is to attract and retain qualified employees. Our compensation program is designed to reward the named executive officers for individual performance, Company performance and increases in stockholder value. Accordingly, executive compensation is based on our pay-for-performance philosophy, which emphasizes executive performance measures that correlate closely with the achievement of both shorter-term performance objectives and longer-term stockholder value. The Compensation Committee regularly reviews our executive compensation program to assure that it continues to meet these overall objectives.

26

We believe that the information we have provided in this Proxy Statement demonstrates that our executive compensation program was designed appropriately and is working to ensure management’s interests are aligned with our stockholders’ interests to support long-term value creation.

The Board of Directors unanimously recommends a vote “FOR” the following resolution:

RESOLVED, that the compensation of the named executive officers as disclosed in the Proxy Statement is approved.

VOTE REQUIRED

Assuming a quorum is present at the Annual Meeting, this proposal will be approved if it receives the affirmative vote of a majority of votes cast by holders of shares of Common Stock present in person or represented by proxy and entitled to vote at the Annual Meeting.

ITEM 3 — RATIFICATION OF APPOINTMENT OF KPMG LLP AS INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2022

The Audit Committee has appointed KPMG LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2022. KPMG LLP served as the Company’s independent registered public accounting firm for the year ended December 31, 2021. A representative of KPMG LLP will be present, in person or via telephone, at the Annual Meeting, will have an opportunity to make a statement, if desired, and will be available to respond to appropriate questions from stockholders.

Although this appointment is not required to be submitted to a vote of stockholders, the Board of Directors believes it is appropriate to request that the stockholders ratify the appointment of KPMG LLP as the Company’s independent registered accounting firm for the year ending December 31, 2022. If the stockholders do not so ratify, the Audit Committee will investigate the reasons for the stockholders’ decision, and depending on the results of such investigation, may reconsider the appointment of the independent registered public accounting firm.

The Board of Directors unanimously recommends a vote “FOR” ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2022.

VOTE REQUIRED

Assuming a quorum is present at the Annual Meeting, this proposal will be approved if it receives the affirmative vote of a majority of votes cast by holders of shares of Common Stock present in person or represented by proxy and entitled to vote at the Annual Meeting.
