Dear Shareholder,
Tennant Company’s 2022 Annual Meeting of Shareholders will be held on Tuesday, April 26, 2022, at 10:30 a.m. Central Time. This year’s Annual Meeting will be a completely virtual meeting of shareholders. You may attend the meeting and vote your shares electronically during the meeting via the Internet by visiting www.virtualshareholdermeeting.com/TNC2022.
The attached Notice of Annual Meeting and Proxy Statement describe the business to be conducted at the meeting. We have chosen to provide access to our proxy materials over the Internet under the Securities and Exchange Commission’s “notice and access” rules. We believe that providing our proxy materials over the Internet reduces the environmental impact of our meeting without limiting our shareholders’ access to important information about Tennant.
Whether or not you plan on joining the meeting, it is important that your shares be represented and voted at the meeting. We encourage you to read the Proxy Statement and vote your shares, as instructed in the Notice of Internet Availability of Proxy Materials, as soon as possible. You may also follow the instructions on the Notice of Internet Availability of Proxy Materials to vote by telephone or request a paper proxy card, which will include a reply envelope, to submit your vote by mail.
We appreciate your continued confidence in Tennant and look forward to you joining the virtual meeting.
Sincerely,
Kristin A. Stokes
Senior Vice President, General Counsel and Corporate Secretary

TENNANT COMPANY PROXY STATEMENT
WHY DID I RECEIVE A NOTICE OF INTERNET AVAILABILITY OF PROXY MATERIALS?
Tennant Company (“we,” “us,” “our,” or the “company”), on behalf of its Board of Directors, is providing this Proxy Statement in order to obtain your vote in connection with its 2022 Annual Meeting of Shareholders (“Annual Meeting”).
The completely virtual Annual Meeting will be held on Tuesday, April 26, 2022, at 10:30 a.m. Central Time at www.virtualshareholdermeeting.com/TNC2022.
The Notice of Internet Availability of Proxy Materials is being first mailed to shareholders on or about March 17, 2022.
HOW DO I ACCESS THE PROXY MATERIALS?
Under rules of the Securities and Exchange Commission, we are furnishing proxy materials to our shareholders via the Internet, rather than mailing printed copies.
If you received a Notice of Internet Availability of Proxy Materials by mail, you will not receive a printed copy of the proxy materials unless you request one as instructed in that notice. Instead, the Notice of Internet Availability of Proxy Materials will instruct you as to how you may access and review the proxy materials and vote via the Internet.
If you received a Notice of Internet Availability of Proxy Materials by mail and would like to receive a printed copy of our proxy materials, please follow the instructions included in the Notice of Internet Availability of Proxy Materials.
WHAT IS A PROXY?
The proxy serves as a ballot for elections to our Board, and it provides information about other items to be discussed and voted on at the Annual Meeting. It allows an authorized agent to act on your behalf in the event you do not attend the Annual Meeting.
WHO IS ENTITLED TO VOTE?
You may vote if you owned shares of our common stock as of the close of business on March 3, 2022. As of March 3, 2022, there were 18,573,473 shares of common stock outstanding, each entitled to one vote.
HOW DO I VOTE?
You may vote in one of four ways:
1. By Internet
You may access the website at www.proxyvote.com to cast your vote 24 hours a day, 7 days a week, until 11:59 p.m. Eastern Time on April 25, 2022. Please have your Notice of Internet Availability of Proxy Materials or, if you have requested one, your proxy card, in hand and the last four digits of your social security number available to verify your identity. Follow the instructions provided to obtain your records and create an electronic ballot.
2. By Phone

a week, until 11:59 p.m. (Eastern Time) on April 25, 2022. Have your proxy card in hand when calling. You will need to provide the last four digits of your social security number to verify your identity. Follow the voice prompts to cast your vote.
3. By Mail
Request a proxy card from us by following the instructions on your Notice of Internet Availability of Proxy Materials. Mark, sign and date your proxy card and return it in the postage-paid envelope that will be provided, or return it to Tennant Company, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.
4. Online during the Annual Meeting
All shareholders may vote online during the Annual Meeting through the link www.virtualshareholdermeeting.com/TNC2022. The 16-digit control number provided on your Notice of Internet Availability of Proxy Materials or proxy card is necessary to access this site. See below for instructions on voting if your shares are held through a third party.
What happens if my shares are held in an account at a brokerage firm, bank, broker-dealer or similar organization?
If your shares are held in an account at a brokerage firm, bank, broker-dealer or other similar organization, you are the beneficial owner of shares held in “street name,” and the Notice of Internet Availability of Proxy Materials was forwarded to you by that organization. The organization holding your account is considered the shareholder of record for purposes of voting online during the Annual Meeting.
As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account. You should follow the instructions received from that organization to vote your shares. Shares held beneficially in street name may be voted online during the Annual Meeting only if you obtain a legal proxy from the broker, trustee or nominee that holds your shares giving you the right to vote the shares.
WHAT HAPPENS IF MY SHARES ARE HELD IN THE TENNANT COMPANY RETIREMENT SAVINGS PLAN?
If your shares are held in the Tennant Company Retirement Savings Plan (“Savings Plan”), your vote will be communicated to the Trustee who will vote all shares held in the Savings Plan in proportion to votes cast by all participants who submit voting instructions. Your proxy includes any shares you hold in the Savings Plan. To be effective, your voting instructions must be received by the Trustee by April 21, 2022. Shares held in the Savings Plan may not be voted online during the Annual Meeting.
CAN THE TRUSTEE VOTE MY SHARES ON MY BEHALF WITHOUT RECEIVING VOTING INSTRUCTIONS FROM ME?
The Trustee will vote all shares held in the Savings Plan in proportion to votes cast by all participants who submit voting instructions timely. You should vote your shares by following the instructions described above and set forth on your proxy card.
WHY SHOULD I VOTE?
Your vote ensures that your ownership interests are represented even if you are unable to join the Annual Meeting online. A promptly voted proxy will save us additional solicitation expense.
MAY I REVOKE MY PROXY OR CHANGE MY VOTE?
Proxies may be revoked at any time before being voted online during the Annual Meeting. The proxy may be revoked or changed only by use of the following methods:
•
Sending a signed, written notice of revocation, dated later than the proxy, to the attention of our Corporate Secretary at the address listed on page 4 of this Proxy Statement;
​
•
Sending a signed proxy, dated later than the prior proxy, to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717;

​
•
Joining the online Annual Meeting and voting online during the meeting.
​
For shares held in an account at a brokerage firm, bank, broker-dealer or other similar organization, or in the Savings Plan, see restrictions described above.
HOW MANY VOTES ARE NEEDED TO HOLD THE ANNUAL MEETING?
The meeting can take place when holders of a majority of the outstanding shares of common stock, either online or by proxy, are present at the meeting. This is known as a quorum. Abstentions and broker non-votes will be counted as present when determining whether a quorum exists.
WHAT IS A BROKER NON-VOTE?
Broker non-votes are shares held of record by a broker that are not voted on a matter because the broker has not received voting instructions from the beneficial owner of the shares and either lacks or declines to exercise the authority to vote the shares in its discretion.
HOW MANY VOTES ARE NEEDED TO APPROVE EACH OF THE PROPOSALS AND HOW ARE VOTES COUNTED?
The table below summarizes the vote required to approve each proposal and how votes are counted:

​ | ​ | ​ | Vote Required | ​ | ​ | Voting Options | ​ | ​ | Board Recommendation(1) | ​ | ​ | Broker Discretionary Voting Allowed(2) | ​ | ​ | Impact of Abstention | ​
Item 1: Elect two Class III directors to three-year terms, such that the total number of directors is eight. | ​ | ​ | Majority of votes cast (the votes cast FOR the nominee exceed the votes cast AGAINST the nominee)(3) | ​ | ​ | FOR AGAINST ABSTAIN | ​ | ​ | FOR | ​ | ​ | No | ​ | ​ | None | ​
Item 2: Ratify the appointment of Deloitte & Touche LLP as the company’s independent registered public accounting firm for 2022 | ​ | ​ | Majority of shares present or represented by proxy at the meeting and entitled to vote(4) | ​ | ​ | FOR AGAINST ABSTAIN | ​ | ​ | FOR | ​ | ​ | Yes | ​ | ​ | AGAINST | ​
Item 3: Advisory approval of executive compensation | ​ | ​ | We will consider shareholders to have approved the advisory vote on our executive compensation if the votes cast FOR exceed the votes cast AGAINST | ​ | ​ | FOR AGAINST ABSTAIN | ​ | ​ | FOR | ​ | ​ | No | ​ | ​ | None | ​

​
(1)
If you submit a proxy without giving specific voting instructions, your shares will be voted in accordance with the Board’s recommendations set forth in the table.
​
(2)
If broker discretionary voting is not allowed, your broker will not be able to vote your shares on these matters. A broker non-vote will have no effect on the matter except in the case of Item 3 where a broker non-vote will have the same effect as a vote AGAINST if a majority of the voting power of the minimum number of shares entitled to vote that would constitute a quorum at the annual meeting is required in order to approve the item as described in footnote (4) below.
​

TABLE OF CONTENTS
(3)
To address a provision in Minnesota law that allows a director who has not been re-elected to remain in office until a successor is elected and qualified, we have a policy requiring any director who does not receive a greater number of votes FOR than AGAINST his or her election in an uncontested election to tender his or her resignation from the Board. Under this policy, the Board, upon recommendation of our Governance Committee, will determine whether to accept or reject the offer to resign and disclose its decision and rationale within 90 days after the date of the election. The text of this policy appears in our Corporate Governance Principles, which is available on our website.
​
(4)
If greater, the vote required is a majority of the voting power of the minimum number of shares entitled to vote that would constitute a quorum at the Annual Meeting.
​
WHO WILL PAY THE COST OF THIS PROXY SOLICITATION?
We will bear the cost of solicitation. Proxies may be solicited on our behalf by directors, officers, employees or others, in person or by telephone, electronic transmission and facsimile transmission. No additional compensation will be paid to such persons for such solicitation. We will reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for reasonable expenses incurred by them in sending proxy materials to beneficial owners of shares.
WHY IS THE ANNUAL MEETING VIRTUAL AND CAN I SUBMIT QUESTIONS?
Hosting a virtual Annual Meeting provides expanded access, improved communication and cost savings for our shareholders and us and enables shareholder participation from any location around the world. Shareholders may submit questions during the Annual Meeting at www.virtualshareholdermeeting.com/TNC2022, and management will respond to questions in the same way as it would if the company held an in-person meeting. If you have questions, you may type them in the dialog box provided at any point during the meeting until the floor is closed to questions.
WHAT ADDRESS SHOULD I USE FOR CORRESPONDENCE WITH THE COMPANY?
The address for our principal executive office is 10400 Clean Street, Eden Prairie, Minnesota, 55344.

MEETING ATTENDANCE
During 2021, the Board met on seven occasions. All directors attended at least 98% of the meetings of the Board and any Board committees of which they were members in 2021. As set forth in the Corporate Governance Principles, all members of the Board are encouraged to attend the annual meetings of shareholders. All of the then-serving directors attended the 2021 Annual Meeting of Shareholders.
DIRECTOR INDEPENDENCE
Our Board uses criteria established by the New York Stock Exchange (“NYSE”) and the Securities and Exchange Commission to determine director independence. The Governance Committee reviews relevant information no less than annually to determine whether the Board members meet the applicable criteria. The Board has determined that Mmes. Arvani, Eicher and Green and Messrs. Austen, Morse, Mulligan, Sonnenberg, and Windley are independent based on the standards referred to above.
The only relationships that exist between directors and the company or management are ordinary course of business commercial transactions involving the purchase of our products and product maintenance services by companies that employ certain directors or our purchase of products and services from companies that employ certain directors. These transactions were considered by the Board in determining director independence.
BOARD LEADERSHIP STRUCTURE
Our Board has four standing committees: Audit, Compensation, Governance and Executive. Each of the Board committees is comprised solely of independent directors with each committee having its own chair.
Prior to March 1, 2021, we did not have a Chair of the Board and instead the Board appointed an independent Lead Director who, together with the CEO, served as Board leaders. Effective March 1, 2021, the Board appointed Mr. Sonnenberg as Chairman of the Board of Directors. As Chairman of the Board,
14

TABLE OF CONTENTS​
Mr. Sonnenberg will continue to perform the duties he performed as Lead Director, including working with the CEO to set and approve the agenda of Board meetings, ensure that there is an appropriate flow of information to and from the Board, and ensure that management properly and adequately addresses matters of interest to the Board. In addition, as Chairman, Mr. Sonnenberg will conduct Board meetings and continue to facilitate meetings of the Executive Committee, which consists of all non-employee directors.
The Board believes the current structure with an engaged, independent Chairman fosters good communication between management and the Board, provides strong independent leadership to oversee and challenge management and provides the optimal level of Board involvement in strategic decision-making and risk oversight.
Under our Corporate Governance Principles, if at any time we do not have an independent Chair of the Board, the Board will again appoint an independent Lead Director.
BOARD OVERSIGHT OF STRATEGY AND RISK
General
Our Board takes an active role in risk oversight of the company both as a full Board and through its committees. The agendas for the Board and committee meetings are specifically designed to include an assessment of opportunities and risks inherent in our operations, strategies and compensation plans.
Our Board typically meets in executive session at the beginning and at the end of each regularly scheduled meeting. The executive sessions are used to assist the Board in carrying out its duties, including risk oversight. We believe that the process followed by the independent directors and led by our independent Chair of the Board provides an appropriate level of risk oversight by the Board.
Annual Risk Assessment Process
We conduct an annual enterprise-wide risk assessment. A formal report is delivered to the Audit Committee and to the Board each December. Risk assessment updates are provided at quarterly Audit Committee or Board meetings and more frequently if requested by a committee, our Board or recommended by management.
The objectives for the risk assessment process include (i) facilitating the NYSE governance requirement that the Audit Committee discuss policies around risk assessment and risk management, (ii) developing and addressing a defined list of key risks to be shared with the Audit Committee, Board and management, (iii) reviewing management’s risk mitigation efforts, (iv) determining whether there are risks that require additional or higher priority mitigation efforts, (v) facilitating discussion of the risk factors to be included in Item 1A of our Annual Report on Form 10-K, and (vi) guiding the development of the next year’s audit plans.
The risk assessment process is co-lead by our outsourced internal auditor and members of an internal risk committee consisting of senior level staff from the legal, compliance, and finance departments and from the global business functions. Together they (i) review our enterprise risk assessment process and methodology, (ii) conduct a detailed enterprise risk assessment, including a survey of key department and functional leaders from all geographies, (iii) communicate the results of the risk assessment with a prioritization of key risks, (iv) evaluate management’s past mitigation efforts, (v) assess management’s preparedness to address the identified risks; (vi) assign a member of management to each risk identified to develop risk mitigation activities, and (vii) develop a cadence for implementation of proactive assessments and audits. The process links the risk areas with our strategies, objectives and entity-level controls where senior management and global employees participate in risk identification and ranking and assessment of management preparedness to address identified risks. The risk profiles and current and future mitigating actions are discussed and refined during subsequent discussions with senior management. The identified risks are prioritized based on the potential exposure to the business and measured as a function of severity of impact and likelihood of occurrence, after taking into account management’s preparedness.

Non-Ordinary Course Expenditure Policy
To monitor transactions that could potentially expose the company to risk, the Board has a formal delegation-of-authority policy for non-ordinary course expenditures that specifies areas for which Board review and approval are required.
Compensation Risk Review
As part of our broader enterprise risk management efforts, management and the Compensation Committee annually review the risk associated with our executive and non-executive compensation plans and policies globally (for purposes of this discussion, “plans”) to ensure any risks that are reasonably likely to have a material adverse effect on the company are identified and controlled for or mitigated appropriately. We conduct a multi-step internal assessment with a final review conducted by the chief administration officer, chief financial officer and general counsel. Pearl Meyer & Partners, LLC, the company’s independent compensation consultant (“Pearl Meyer”), is consulted throughout the risk assessment process.
In December 2021, management presented to the Compensation Committee an analysis of our compensation plans and a review of the key areas of potential risks. To assess whether the plans encourage unnecessary or excessive risk taking, management considered the plan design, strategy and philosophy for cash and equity incentive plans, how the incentives are likely to impact employee behavior, the appropriateness of the plan metrics and what checks and balances exist to mitigate risks for inappropriate or fraudulent behavior. Management’s assessment was that the risks arising from our compensation plans do not encourage excessive risk-taking that would likely have a material adverse effect on the company’s financial condition. The Compensation Committee discussed this conclusion with management and reviewed the level of enterprise risk associated with our executive and non-executive employee compensation plans.
Regarding the executive plans, the Compensation Committee concluded that the plans mitigate unnecessary risk, considering both designs and by the controls placed upon the designs, due to numerous factors:

​ | • Balanced pay mix between fixed versus variable and cash versus equity ​ | ​ | ​ | • Minimum performance requirements and maximum payout opportunities for incentive plans ​ | ​
​ | • Incentive plan performance metrics are distinct and balance multiple measures of performance ​ | ​ | ​ | • Our Compensation Committee can directly retain outside experts in fulfilling their charter obligations ​ | ​
​ | • Performance targets are calibrated to align with our strategy and long-term value creation ​ | ​ | ​ | • We maintain strong internal governance controls over the calculation of performance results ​ | ​
​ | • Our Compensation Committee approves goals and payouts and has ultimate authority to adjust payments as necessary ​ | ​ | ​ | • We maintain strong governance policies including ownership guidelines, a claw-back policy, and prohibitions on stock hedging or pledging ​ | ​

BOARD COMMITTEES
As mentioned above, we have four standing committees of the Board: Audit, Compensation, Governance and Executive. Membership on these committees is limited to independent directors. Each committee operates under a written charter and evaluates its charter annually.
Audit Committee
Our Audit Committee is comprised of Donal L. Mulligan (Chair), William F. Austen, Maria C. Green, Timothy R. Morse, and Steven A. Sonnenberg. Our Board uses the listing standards of the NYSE to determine whether the Audit Committee members possess the requisite financial literacy to serve on the committee. The Board has determined that all Audit Committee members are financially literate and independent.
At least one member of the Audit Committee must have accounting or related financial management expertise as required by NYSE rules. The Audit Committee endeavors to have at all times a member who
16

TABLE OF CONTENTS
qualifies as an “audit committee financial expert” as defined by the Securities and Exchange Commission. The Board has determined that Messrs. Morse and Mulligan, each with extensive experience in financial management, satisfy the requirements of an “audit committee financial expert,” and that their expertise has been acquired through training and relevant experience.
The Audit Committee is required to meet no less than four times throughout the year and in 2021 met on six occasions.
The primary functions of the Audit Committee are to oversee:
•
the integrity of our financial statements;
​
•
compliance with legal and regulatory requirements;
​
•
the independent registered public accounting firm’s qualifications, independence and performance;
​
•
the performance of the internal audit function;
​
•
the performance of the system of internal controls over financial reporting;
​
•
the ethics compliance program;
​
•
risk assessment and risk management policies; and
​
•
significant financial matters.
​
Compensation Committee
Our Compensation Committee is comprised of David Windley (Chair), Azita Arvani, William F. Austen, and Carol S. Eicher, all of whom meet the criteria for independence under the NYSE listing standards and Rule 16b-3 of the Securities Exchange Act of 1934.
The Compensation Committee is required to meet no less than four times throughout the year. In 2021, the Compensation Committee held five meetings.
A primary function of the Compensation Committee is to assist the company in maximizing shareholder value by ensuring that executive officers are compensated in accordance with our philosophy, objectives and policies. The Compensation Committee’s duties include, among other things, approving executive compensation policies and strategies; evaluating executive officers’ compensation levels and payouts against performance goals; approving and administering compensation plans; overseeing certain compensation disclosures in the proxy statement; and overseeing risks associated with our compensation policies and practices. In addition, in conjunction with its outside compensation consultant, the Compensation Committee recommends compensation levels for non-employee directors for approval by the Board.
Use of Outside Compensation Consultant
Our Compensation Committee engages Pearl Meyer to advise it on executive officer and non-employee director compensation. Pearl Meyer’s services include (i) making recommendations regarding the form and amounts of executive officer and non-employee director compensation, (ii) providing market and performance data as a backdrop to the committee’s decisions regarding executive officer and non-employee director compensation, and (iii) advising the committee as to best practices and recent legal, governance and regulatory considerations regarding executive officer and non-employee director compensation.
Pearl Meyer reports directly to the Compensation Committee and works collaboratively, as directed by the Chair of the committee, with management. In 2021, the committee concluded that Pearl Meyer was independent with respect to the services it provided because (i) it reported directly to the committee, (ii) the committee could solicit advice and consultation from it without management’s direct involvement, and (iii) all of the services provided by it in 2021 were at the request of the committee. In addition, the Compensation Committee assessed the independence of Pearl Meyer pursuant to rules established by the Securities and Exchange Commission and the NYSE, and concluded that no conflict of interest exists that would prevent Pearl Meyer from independently advising the committee.
17

TABLE OF CONTENTS
The Compensation Committee has established a process to limit potential conflicts of interest should management desire to seek advice from Pearl Meyer for non-executive compensation matters. Specifically, the committee determined that if management desires to use Pearl Meyer to provide any advice on non-executive compensation matters, it must contact the committee Chair and inform him or her of such request. The committee delegated to the Chair the authority to make a decision as to whether the service is appropriate. The Chair is required to inform the committee of any such request or approval granted no later than at the next scheduled committee meeting. No less than annually Pearl Meyer must provide a summary to the committee describing any non-executive compensation services provided to the company or management. No such services were provided in 2021.
Additional information about Pearl Meyer’s role is set forth below under “Compensation Discussion and Analysis — Compensation Determination Process.”
Governance Committee
Our Governance Committee is comprised of Carol S. Eicher (Chair), Azita Arvani, Maria C. Green, Donal L. Mulligan, Steven A. Sonnenberg, and David Windley.
The Governance Committee is required to meet at least two times throughout the year. In 2021, the Governance Committee met on four occasions, including one meeting dedicated to oversight of the company’s programs, policies and practices relating to corporate responsibility and sustainability, including environmental, social and corporate governance (ESG) matters. The primary purpose of the Governance Committee is to:
•
assist the Board in identifying individuals qualified to become Board members;
​
•
determine the composition of the Board and its committees;
​
•
develop and maintain criteria and procedures for the identification and recruitment of candidates for election to serve as directors;
​
•
lead the Board in its annual performance review and coordinate its self-evaluation process;
​
•
oversee the company’s ESG matters;
​
•
regularly review and, when applicable, recommend to the Board changes to the Corporate Governance Principles, Business Ethics Guide, Articles of Incorporation and By-Laws of the company and certain Board committee charters; and
​
•
assist the Board in understanding and complying with new corporate governance laws, regulations and policies affecting us or our business.
​
Executive Committee
Our Executive Committee is comprised of the independent Board members. Mr. Sonnenberg, as Chair of the Executive Committee and Chairman of the Board, presides at the Executive Committee meetings.
The Executive Committee is to meet no less than four times throughout the year and in 2021 met on seven occasions at either the beginning or the end of each Board meeting.
The primary purpose of the Executive Committee is to review such matters and take such actions as are appropriate to be reviewed or taken by the independent directors, including, among other things, overseeing the annual CEO evaluation process, reviewing and approving our management succession plan, and overseeing our long-term strategic direction. Any meeting of the Executive Committee held at the beginning of a regularly scheduled Board meeting generally is used to discuss the Board’s priorities and focus on the agenda topics for that meeting. Any meeting of the Executive Committee held following a regularly scheduled Board meeting is generally used to, among other things, assess the quality of the meetings and to collect feedback for the Chairman of the Board to present to the CEO and management. Such feedback includes any requests for specific information relating to our long-term strategic direction, the annual CEO performance review, the compensation of our CEO, our management succession plan, the risks and opportunities inherent in our strategic decision making, future agenda items, and other materials.

TABLE OF CONTENTS​​
BOARD AND COMMITTEE SELF-EVALUATION PROCESS
The Board and its committees generally conduct an annual performance evaluation as follows: annually in October, Board members complete a detailed questionnaire which asks for quantitative ratings and subjective comments in key areas covering Board and committee matters. Responses are collected by the General Counsel and a compilation of all the responses is provided to the Governance Committee. In addition, management prepares a response memorandum to the Chair of the Governance Committee. Upon review by the Governance Committee, the compilation of responses and management’s response memorandum are provided to the Board and each committee for review and discussion. Each committee thereafter provides an evaluation summary to the Board. Feedback is then provided to management through the Chairman of the Board.
BOARD AND COMMITTEE MEMBER NOMINATIONS AND APPOINTMENTS
Committee Appointments
Our Board appoints members of its committees at least annually upon recommendation of the Governance Committee after taking into account the desires, experiences and expertise of individual directors, the recommendations of our CEO and the benefits of rotating committee membership.
Director Nomination Process
Our Governance Committee is responsible for recommending nominees for election to the Board. As required by the Corporate Governance Principles, the Governance Committee is responsible for reviewing with the Board, on an annual basis, the requisite skills and characteristics of individual members. The committee must also balance the composition of the Board, as a whole, with the needs of the company.
Our Governance Committee reviews all director nominees and recommends to the Board those persons whose attributes it believes are most beneficial to the company. The committee’s assessment of each director nominee takes into consideration the needs of the Board, the ability to effectively represent the shareholders and stakeholders generally, as well as the following attributes:

​ | • Experience ​ | ​ | ​ | • Diversity ​ | ​
​ | • Expertise ​ | ​ | ​ | • Skills (including interpersonal) ​ | ​
​ | • Integrity ​ | ​ | ​ | • Dedication ​ | ​
​ | • Competence ​ | ​ | ​ | ​ | ​

The Board does not have a written policy regarding consideration of diversity in identifying director nominees. However, as indicated above, diversity is one of the factors that the Board takes into consideration when assessing director nominees. In that regard, the Board defines “diversity” broadly to include race, gender, national origin, functional experience, geographic representation and personal skills and attributes.
The Board looks for candidates who have public company experience, have a history of demonstrating strong and ethical leadership, are sufficiently senior and adept at understanding and evaluating strategic, financial, operational and global risks, and have the expertise to create a well-rounded Board. The Governance Committee also considers the Corporate Governance Principles, which include the following factors when considering director nominees:

​ | • The size of the Board ​ | ​ | ​ | • Other board service ​ | ​
​ | • Directors with job changes ​ | ​ | ​ | • Retirement ​ | ​
​ | • Director terms ​ | ​ | ​ | • Independence ​ | ​

Shareholder Nominations
The Governance Committee will consider director candidates recommended by shareholders. Shareholder recommendations must be accompanied by a sufficiently detailed description of the candidate’s background and qualifications. The committee will evaluate the candidate using the aforementioned
19

TABLE OF CONTENTS​​​
criteria. To recommend a qualified candidate, shareholders should write to the Chair of the Governance Committee at the address listed below.
If a shareholder wishes to nominate a director, under our Restated Articles of Incorporation, a shareholder of record must submit to the Corporate Secretary a written request that a person’s name be placed in nomination. This request must be received not less than 75 days prior to the date fixed for our annual meeting, along with the written consent of the proposed nominee to serve as a director.
COMMUNICATION WITH THE BOARD OF DIRECTORS
All interested parties, including shareholders, may communicate with the independent members of the Board by writing to our Chairman of the Board at:
ATTN: General Counsel
Tennant Company
10400 Clean Street
Eden Prairie, MN 55344
All communications will be delivered to the General Counsel who will forward communications to our Chairman of the Board to address the matter.

DIRECTOR COMPENSATION
Our non-employee director compensation program is designed to be competitive and to align the interests of our non-employee directors with the long-term interests of our shareholders. Our director compensation program is reviewed annually by the Compensation Committee using external data derived from our outside compensation consultant’s review of peer company proxy data used in the executive compensation determination process. Our directors are compensated for their services at the start of each Board Year. We define “Board Year” for director compensation purposes as the time between annual shareholder meetings.
Director Compensation for 2021-2022 Board Year
Each year, the Compensation Committee requests that its independent compensation consultant review the competitiveness of the current pay program to determine whether changes should be considered for the upcoming Board Year. Pearl Meyer analyzes the market competitiveness of our non-employee director pay program, including all role-based retainers and fees, and reviews each element of the pay program against our comparator group and, as a secondary reference point, against size-appropriate all-industry survey data. Based on the review of compensation competitiveness and review of market benchmarking data, and in conjunction with the change in our board leadership structure, the Compensation Committee voted to increase the Board Year Compensation for Annual Lead Director/Chair of the Board Retainer from $60,000 to $75,000, which increase became effective on April 28, 2021.
20

TABLE OF CONTENTS
There were no other changes made for 2021-2022 Board Year compensation. The 2021-2022 Board Year compensation is as follows:

Component of Pay | ​ | ​ | Board Year Compensation | ​
Annual Board Retainer | ​ | ​ | $65,000 | ​
Annual Committee Member Retainer | ​ | ​ | Audit: $15,000 | ​
​ | ​ | ​ | Compensation: $6,000 | ​
​ | ​ | ​ | Governance: $5,000 | ​
Annual Additional Committee Chair Retainer | ​ | ​ | Audit: $10,000 | ​
​ | ​ | ​ | Compensation: $10,000 | ​
​ | ​ | ​ | Governance: $5,000 | ​
Chair of the Board Retainer | ​ | ​ | $75,000 | ​
Annual Equity Grant | ​ | ​ | $110,000 aggregate grant date fair value of restricted stock units | ​

Retainer fees are paid in cash and non-employee directors may elect to defer the retainer fees under the Tennant Company Executive Non-Qualified Deferred Compensation Plan. For additional information on this plan, see the Non-Qualified Deferred Compensation discussion under “Compensation Discussion and Analysis — Other Plans and Agreements — Supplemental Retirement Savings Plan (Non-Qualified Deferred Compensation).” All compensation paid to directors who join the Board between annual shareholder meetings is pro-rated for partial year of service.
Non-employee directors received annual grants of restricted stock units under the 2020 Stock Incentive Plan having an aggregate fair value of $110,000, subject to rounding adjustments described below. The number of restricted stock units granted is determined by dividing $110,000 by the closing price of our common stock on the last trading day prior to the date of grant, rounded to the nearest share. The restricted stock units vest one year from the date of grant and convert into an equal number of shares of our common stock. A director may defer receipt of the shares until his or her service as a director ends or until a pre-established date set forth in the irrevocable deferral election form applicable to the award. Dividend equivalents on outstanding restricted stock units are accrued at the same rate that dividends are paid to our shareholders, are subject to the same vesting conditions as the underlying units and are paid in cash at the same time as the underlying units are settled.
The table below summarizes compensation paid to each person who served as a non-employee director during fiscal 2021.

Stock Ownership Goal for Non-Employee Directors
The Board has adopted a stock ownership goal for non-employee directors of five times their annual cash retainer, to be attained within five years from the date of election to the Board. Progress toward the ownership goal is measured each year at the time of the February Compensation Committee meeting. Ownership levels are calculated by adding (i) the value of the shares held directly by the director, (ii) the estimated after-tax value of restricted and unrestricted shares, and (iii) the potential gains from vested options, as of the close of market on December 31 of the year immediately preceding the year of calculation. Directors who have served on the Board for five years or more have achieved their goals. Newer Board members are on pace for achieving their ownership targets within the five-year period.
ITEM 1 — ELECTION OF DIRECTORS
Our Restated Articles of Incorporation provide that the Board will be divided into three classes of directors of as nearly equal size as possible, and the term of each class of directors is three years. Currently, we have nine directors with three directors serving in Class I, three directors serving in Class II, and three directors serving in Class III. However, as previously disclosed, Mr. Austen (Class III) will retire from the Board at the Annual Meeting such that the total number of directors will be eight. At the Annual Meeting, two Class III directors are to be elected for three-year terms. If elected, each Class III director will serve until their terms expire at the time of the Annual Meeting in 2025 and, in case, until their successors are elected and have qualified. Each nominee has expressed his willingness to serve. In the event that any of the nominees is not a candidate at the Annual Meeting, it is the intention of the named proxies to vote in favor of the remaining named nominees and to vote for a substitute nominee selected by the Governance Committee.
The Board, upon recommendation of the Governance Committee, has designated David W. Huml and David Windley as nominees for election as Class III directors at the Annual Meeting to serve three-year terms expiring in 2025. All nominees currently serve on our Board and were previously elected by shareholders.
The Board of Directors, upon recommendation of the Governance Committee, unanimously recommends a vote FOR each of the director nominees.

(1)
Audit Fees include professional services rendered in connection with the audit of our annual consolidated financial statements, audits of our internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, quarterly reviews of financial statements included in our Quarterly Reports of Form 10-Q, and statutory audits of certain of our international subsidiaries, as well as other filings with the Securities and Exchange Commission.
​
(2)
Audit-Related Fees include assurance and related services that are reasonably related to the performance of the audit or review of our financial statements or that are traditionally performed by the independent auditor (but not included in the “Audit Fees” category above), such as employee benefit plan audits, and agreed-upon procedures required to comply with financial, accounting, or regulatory reporting.
​

Tax Fees include professional services rendered in connection with tax audits, which in 2021 consisted primarily of international tax compliance, and tax consulting and planning services. The Audit Committee has adopted a Pre-Approval Policy for Non-Audit Services, which appears on our website as an exhibit to the Audit Committee charter. All audit-related, tax and other non-audit services were performed in compliance with the Pre-Approval Policy. The Audit Committee has determined that the provision of the above non-audit services did not compromise Deloitte’s independence.

A udit C ommittee R eport
The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of Deloitte. The Audit Committee and the Board believe the retention of Deloitte for 2022 is in the best interests of the company and its shareholders.
The Audit Committee’s meetings are designed to facilitate and encourage private communication between the committee and Deloitte. In addition, the committee complied with its charter responsibilities and reviewed and discussed the audited consolidated financial statements with management. The Audit Committee discussed with Deloitte the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the Securities and Exchange Commission. Deloitte also provided to the committee the written disclosures required by applicable requirements of the Public Company Accounting Oversight Board regarding independence, and the committee discussed with Deloitte the firm’s independence.
Based upon the committee’s discussion with management and Deloitte and the committee’s review of audited consolidated financial statements and the report of Deloitte to the committee, the committee recommended that the Board include our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission.

Previous Independent Registered Public Accounting Firm
In 2019, the Audit Committee conducted a competitive process to determine our independent registered public accounting firm for our fiscal year ending December 31, 2020. The company invited several independent registered public accounting firms to participate in this process.
As a result of the review of proposals from the independent registered public accounting firms that participated, on August 27, 2019, the Audit Committee approved the appointment of Deloitte & Touche LLP (“Deloitte”) as our independent registered public accounting firm for our fiscal year ending December 31, 2020, subject to the completion of Deloitte’s standard client acceptance procedures and execution of an engagement letter. KPMG continued as our independent registered public accounting firm for the year ended December 31, 2019, and was dismissed on February 27, 2020, but continued to provide statutory audit services related to the 2019 fiscal year, until complete.
KPMG’s report on the consolidated financial statements of the company as of and for the year ended December 31, 2019 did not contain an adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principles, except as follows:
KPMG’s report on our consolidated financial statements as of and for the year ended December 31, 2019 contained a separate paragraph stating that “As discussed in Note 2 to the consolidated financial statements, the company has changed its method of accounting for leases as of January 1, 2019 due to the adoption of Accounting Standards Update 2016-02, Leases (Topic 842), and related amendments.”
During the year ended December 31, 2019, and the subsequent interim period through February 27, 2020, there were (i) no disagreements as that term is defined in Item 304(a)(1)(iv) of Regulation S-K, between us and KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures which, if not resolved to the satisfaction of KPMG, would have caused KPMG to make reference thereto in their reports; and (ii) no reportable events as described in Item 304(a)(1)(v) of Regulation S-K.
New Independent Registered Public Accounting Firm
During the year ended December 31, 2019, and the subsequent interim period through February 27, 2020, neither the company nor anyone acting on our behalf has consulted with Deloitte regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, and no written report or oral advice was provided to us that Deloitte concluded was an important factor considered by us in reaching a decision as to any accounting, auditing, or financial reporting issue, (ii) any matters that were the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions, or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.
ITEM 2 — RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
At the Annual Meeting, shareholders will vote on the proposal to ratify the appointment of Deloitte as our independent registered public accounting firm for the year ending December 31, 2022. Deloitte is an independent registered public accounting firm. The Audit Committee is responsible for the appointment, compensation and oversight of Deloitte and believes that the retention of Deloitte is in the best interests of

EXECUTIVE COMPENSATION INFORMATION
Compensation Discussion and Analysis
This compensation discussion and analysis (“CD&A”) explains our executive compensation program and describes the process followed by the Compensation Committee (referred to as the “Committee” throughout the CD&A) for making pay and benefit decisions, as well as its rationale for specific decisions made in 2021.
Leadership Transitions Among Named Executives
During 2021, we implemented CEO and CFO succession changes. Mr. Killingstad was our CEO until February 28, 2021, and Mr. Huml became CEO on March 1, 2021.

Executive Summary
Overview of 2021 Performance
2021 was a challenging economic and operating environment for Tennant and companies globally. Our financial performance was impacted by the unexpected and prolonged global supply disruptions, inflation and labor constraints, and continued COVID-related concerns and restrictions. Despite those challenges, Tennant saw a return to pre-pandemic demand across a majority of its markets and we took prompt and effective actions to combat the continuing challenges. Those actions resulted in Tennant beating our internal targets for revenue and EBITDA growth in 2021, and meeting our EBITDA% target and our external guidance for these metrics.
26

TABLE OF CONTENTS
We experienced year-over-year organic revenue growth of 9.1%. Adjusted EBITDA for 2021 was $140.2 million, compared to $119.4 million in 2020 and EBITDA margin remained flat at 12.9%. This performance resulted in above-target payments under the 2021 CIP and 2019-2021 LTIP.
Snapshot of 2021 Compensation Decisions
Based on our performance and consistent with the design of our program, the Committee made the following executive compensation decisions for fiscal 2021:
•
Base salary: Base salaries increased, as discussed below in “Key Compensation Decisions for 2021,” to reflect transitions of Named Executives to new roles and increased responsibilities in continuing roles.
​
•
2021 Executive Officer Cash Incentive Plan (“CIP”): Achievement of financial and strategic objectives resulted in an overall payout of 122.09% of target.
​
•
2021 Long-Term Incentive Plan Awards: Named Executives received 25% of their grant in restricted stock, 25% in stock options and 50% in performance-based restricted stock units (“PRSUs”).
​
•
2019-2021 PRSU Awards: Achievement of financial objectives resulted in an overall payout of 112.24% of target.
​
•
2020-2022 PRSU Awards: In February of 2021, modified ROIC and Cumulative EPS performance goals based on the expected impact to our business from the pandemic to ensure continued management accountability for our performance results.
​
The Committee believes that the design and structure of the company’s incentive program, and the decisions it makes, provides a direct link between company performance and pay outcomes for the executives, as described in greater detail below.
Compensation Governance
We believe the following practices and policies promote sound compensation governance and are in the best interests of our shareholders and Named Executives:

​ | WHAT WE DO | ​ | ​ | WHAT WE DON’T DO | ​
​ | ✓ Heavily emphasize performance-based compensation, using a combination of short- and long-term incentives, to ensure a strong connection between our operating performance and actual compensation ​ ✓ Maintain multi-year vesting requirements for equity compensation awards ​ ✓ Provide 100% of long-term incentives in the form of equity ​ ✓ Enforce rigorous stock ownership guidelines ​ ✓ Maintain a compensation recoupment (claw-back) policy ​ ✓ Maintain a fully independent Compensation Committee ​ ✓ Retain an independent compensation consultant ​ ✓ Annually review risks associated with compensation ​ ✓ Provide shareholders an annual opportunity to cast a say-on-pay vote ​ | ​ | ​ | × Provide gross-up payments to cover excise taxes for executive or severance benefits ​ × Provide excessive or special perquisites ​ × Backdate or reprice stock options ​ × Provide grants of reload stock options ​ × Allow hedging or pledging of Tennant securities by executive officers ​ | ​

TABLE OF CONTENTS
2021 Say-On-Pay
Each year, we carefully consider the results of our shareholder say-on-pay vote from the preceding year. In 2021, approximately 98% of the votes cast supported our executive compensation decisions. Overall, we believe our shareholders are highly supportive of our executive compensation program and its direction. As a result, in 2021, we did not make significant modifications to the structure of our program. We will continue to keep an open dialogue with our shareholders to help ensure that we have a regular pulse on investor perspectives.
What Guides Our Program
Compensation Objectives
Our overall objective is to align executive compensation with our short- and long-term operating goals and the interests of our shareholders.
We seek to offer a comprehensive compensation package that is competitive with those of similarly sized U.S. durable goods manufacturing companies. Our compensation programs take into account that an executive’s actual compensation level may be greater or less than targeted based on our annual and long-term financial performance against preestablished goals, the individual’s performance and the individual’s scope of responsibilities.
Specifically, our compensation programs adhere to the following design philosophy and principles:
•
create a relationship between pay and performance by providing a strong link between our short- and long-term business goals and executive compensation;
​
•
attract and retain high-caliber key executive officers who can create long-term financial success for the company and enhance shareholder return;
​
•
motivate executive officers to achieve our goals by placing a significant portion of pay at risk;
​
•
align the interests of executive officers with those of our shareholders by providing a significant portion of compensation in stock-based awards; and
​
•
discourage risk-taking behavior that would likely have a material adverse effect on the company.
​
Linking Pay and Performance
A key component of our executive compensation philosophy is the link between compensation and overall business results and shareholder value creation. We strive to clearly communicate this to our shareholders and believe that looking at realizable pay relative to our peers (see “Comparator Group” below) can illustrate this point effectively.
The Committee works closely with its outside consultant, Pearl Meyer, to evaluate our compensation programs and ensure adherence to our compensation philosophy. During 2021, Pearl Meyer assessed the relationship between total realizable pay (as defined below) and our Total Shareholder Return (“TSR”) for the three-year period ended December 31, 2020. This approach uses the most recent period coinciding with our fiscal year-end for which corresponding peer group compensation data is also available. The analysis looks at the degree of alignment between total compensation delivered to Named Executives during the review period and our performance relative to our peer group. “Total realizable pay” is defined as the sum of the following components:
•
Actual base salaries paid over the three-year period;
​
•
Actual short-term incentive awards paid for the three-year period;
​
•
The Black-Scholes value as of December 31, 2020, of any stock options granted over the three-year period;
​
•
The value as of December 31, 2020, of restricted shares granted over the three-year period; and
​
•
The value as of December 31, 2020, of PRSUs earned for cycles ending in the three-year period.
​
28

TABLE OF CONTENTS
For peer companies, realizable pay also includes cash-based long-term incentive plan payouts for cycles that ended within the three-year period.
As illustrated in the chart below, realizable pay for our CEO for 2021 and other continuing Named Executives was generally aligned with our relative TSR performance against peers. Realizable pay for the three-year period for our CEO and other Named Executives approximated the 40th percentile. Our TSR over the same period of time was near the 31 st percentile.
Direct Compensation Elements
We seek to achieve our objectives using the following compensation elements:

Element | ​ | ​ | Type | ​ | ​ | Terms | ​
Cash | ​ | ​ | Base Salary | ​ | ​ | Fixed pay element that reflects the value of the executive role. Generally eligible to be increased annually, depending on market conditions, performance and internal equity. | ​
​ | ​ | ​ | Short-Term Cash Incentive Plan (“CIP”) | ​ | ​ | Focuses on achievement of annual goals that are directly linked to execution of the company’s annual operating plan and calibrated to deliver performance-aligned pay. | ​
Long-Term Incentive Plan or “LTIP” ​(100% Equity) | ​ | ​ | ​ | ​ | ​ | The LTIP program focuses on: (1) direct linkage to stock price performance; (2) key financial drivers of shareholder value; and (3) supporting leadership retention objectives and facilitating and encouraging executive retention and stock ownership through the grant of stock options, performance-based restricted stock units, and restricted stock with opportunities calibrated to deliver pay aligned with performance. | ​
​ | ​ | ​ | Performance-Based Restricted Stock Units or PRSUs | ​ | ​ | The performance period for PRSUs is three years. Payment is variable based on the relative achievement of pre-set financial goals. PRSUs are paid in shares of our common stock on settlement. | ​
​ | ​ | ​ | Stock Options | ​ | ​ | Stock options generally vest in equal installments over three years from the grant date and have a ten-year term. | ​

29

TABLE OF CONTENTS

Element | ​ | ​ | Type | ​ | ​ | Terms | ​
​ | ​ | ​ | Restricted Stock | ​ | ​ | Restricted stock generally vests three years from the grant date. Dividends are accumulated on restricted stock during the vesting period and paid in cash upon vesting. | ​
Other Equity | ​ | ​ | Restricted Stock Units (used for one-time grants outside of LTIP program) | ​ | ​ | We may occasionally make one-time RSU grants outside the normal equity grant schedule for specific reasons. The vesting terms of those awards are typically aligned with the specific needs of the Company. RSUs are paid in shares of our common stock on settlement. | ​

Total Direct Compensation: Pay Mix
Our compensation strategy is to target compensation levels within a competitive range of the comparator group at approximately the 50th percentile for base salary and between the 50th and 75th percentile for short-term and long-term incentives, positioning Total Direct Compensation between the 50th and 75th percentile. The Committee believes that this strategy provides sufficient short-term compensation to attract and retain competitive talent, but also places a large portion of pay at risk in the form of performance-based equity to drive long-term performance.
Based on the Committee’s pay decisions, the charts below show the target Total Direct Compensation that the continuing Named Executives received in fiscal 2021. These charts illustrate that a majority of Mr. Huml’s Total Direct Compensation (approximately 79%) is variable and at risk, and an average of 66% of Total Direct Compensation for our continuing Named Executives is variable and at risk, based on our performance.
Role of the Committee in the Compensation Process
The Committee ensures that executive compensation and benefit programs are consistent with our compensation philosophy and other corporate goals and makes decisions regarding Total Direct Compensation (i.e., base salary and short-term and long-term variable pay), other benefits and perquisites for Named Executives, and, subject to final approval from the Executive Committee, the compensation of our CEO.
Compensation Determination Process
The Committee typically meets four times a year to consider various aspects of compensation for the Named Executives and non-employee directors. Among other things, it decides how to allocate each Named Executive’s Total Direct Compensation and determines the target level of Total Direct Compensation for each. The Committee sets Total Direct Compensation and the allocation between each element so that it is consistent with our compensation objectives.
30

TABLE OF CONTENTS
While we do not target any specific mix of compensation, we generally aim to have a compensation program that is in line with benchmarked companies and survey data. In addition, we aim to appropriately balance (i) fixed versus variable compensation, (ii) short- versus long-term compensation, (iii) company versus individual performance, and (iv) shareholder, financial, operational and strategic goals. The balance and mix of incentive compensation are reviewed and determined each year based on short- and long-term objectives of the business.
Annually in December, the Committee conducts a comprehensive review of pay levels for our Named Executives. The Committee sets the Named Executives’ Total Direct Compensation opportunity at its annual February meeting. As part of the review, the Committee receives proxy peer data and other external reference data in the form of published executive compensation surveys from Pearl Meyer.
In setting compensation for 2021, the Committee reviewed data and information from a group of comparatively similar companies and executive compensation surveys to identify competitive market compensation practices and our overall competitive position. The Committee works with Pearl Meyer to review the set of comparator firms (the “comparator group”) and to identify and use appropriate executive compensation survey sources against which we assess the competitiveness of executive pay levels.
In addition, the Committee considers internal data, including each executive officer’s performance, experience, management capabilities and contributions to our operations, and the tactical and strategic value of specific skill sets of certain key executives. When assessing the compensation of our CEO, the Committee and the Executive Committee evaluate our financial performance against that of peer companies and our CEO’s performance against the company’s financial performance goals and strategic initiatives.
In connection with the processes outlined above, for 2021, Ms. McKnight, our Senior Vice President and Chief Administrative Officer, provided input on Mr. Zay’s job scope, executive compensation, and pay changes. The Committee reviewed Mr. Huml’s, Ms. West’s, and Mr. Glusick’s compensation in separate processes, and Ms. McKnight’s compensation was reviewed separately with Mr. Huml and Mr. Killingstad. Pearl Meyer conducted the analysis, reviewed the information in advance with the Chair of the Committee and reviewed management’s compensation recommendations with the Committee. Ms. McKnight was available for questions at the Committee meeting when the compensation of the executive officers, except for our CEO, was discussed, but played no role in determining her own compensation. Pearl Meyer independently met alone with the Committee, without the presence of members of management and in connection with the CEO succession in 2021, to discuss the compensation of our CEO.
Comparator Group
The comparator group is used for benchmarking pay practices, pay levels, and pay program design for Named Executives and for non-employee director compensation. The selection methodology for reviewing and determining the comparator group has generally included: industry, size, market capitalization, revenue, geographic product mix and customer segmentation, and aggregate similarity to our company.
The Committee reviews the comparator group every year to ensure each company remains appropriate for compensation comparison purposes and reflects our size and scope of business. In addition, the Committee reviews and validates the selection criteria every year to ensure it aligns with our business strategies.
In April 2020, the Committee, working with Pearl Meyer, conducted its regular review of the comparator group for 2021 and determined that no changes to the peer group from the prior year would be made. The 19 companies that made up our 2021 comparator group at the time the Committee established 2021 Named Executive and non-employee director compensation are listed below. As of April of 2020, when the peer group was approved by the Committee, these companies had revenues between $398 million and $3,303 million over the prior 12 months and a market cap between $71 million and $7,668 million.

Key Compensation Decisions for 2021
Base Salary
Base salaries and incentive targets for Named Executives are reviewed annually to ensure that they remain competitive and reflect the scope and responsibility of their positions. In making base salary and incentive target decisions, the Committee considers benchmarking data provided by Pearl Meyer, our CEO’s recommendations, current base salary, scope and complexity of the position, experience, individual performance and internal pay equity.
The base salaries reported below reflect the actual base salary rate for the Named Executive and, for Mr. Huml, the base salary reflects his increased base salary rate effective March 1, 2021, which increase was in connection with his appointment as President and Chief Executive Officer. Mr. Zay’s 2021 base salary reflects a 10% increase in connection with his transition from SVP, Technology and Innovation to Chief Commercial Officer. Ms. McKnight’s 2021 base salary reflects a 5% increase to recognize the increased scope and complexity of her responsibilities. As discussed in the section below titled Compensatory Arrangements for CEO Succession, Mr. Killingstad received a reduction in pay that corresponded to his transition from Chief Executive Officer to Strategic Adviser on March 1, 2021.
Based on their respective hiring dates, Ms. West and Mr. Glusick were not eligible for a salary adjustment in 2021.

​ | ​ | ​ | Annualized Base Salary | ​
​ | ​ | ​ | 2020 | ​ | ​ | 2021 | ​ | ​ | % Increase | ​
David W. Huml | ​ | ​ | ​ | $ | 500,000 | ​ | ​ | ​ | ​ | $ | 800,000 | ​ | ​ | ​ | ​ | ​ | 60% | ​ | ​

Carol E. McKnight | ​ | ​ | ​ | $ | 367,377 | ​ | ​ | ​ | ​ | $ | 385,746 | ​ | ​ | ​ | ​ | ​ | 5% | ​ | ​
Daniel E. Glusick | ​ | ​ | ​ | ​ | — | ​ | ​ | ​ | ​ | $ | 360,000 | ​ | ​ | ​ | ​ | ​ | ​— | ​ | ​
H. Chris Killingstad | ​ | ​ | ​ | $ | 840,000 | ​ | ​ | ​ | ​ | $ | 400,000 | ​ | ​ | ​ | ​ | ​ | (52)% | ​ | ​

Due to Mr. Cebulla’s voluntary termination of employment as Interim CFO shortly into the 2021 Fiscal Year and the temporary nature of Mr. Paulson’s service as Interim CFO, neither individual was considered or eligible for a base salary adjustment in 2022.
Incentive Awards
The Committee approved target award amounts for the Named Executives for 2021 for annual cash incentive awards under the company’s Executive Officer Cash Incentive Plan (“CIP”) and for long-term equity awards (“LTI” or “LTIP”). The table below shows the incentive targets, expressed as a percentage of base salary, for each Named Executive for 2020 and 2021. The adjustments for 2021 incentive targets were generally intended to align with competitive market data and, in the case of Mr. Huml and Mr. Killingstad, include pro-rated CIP incentive targets based on their different base salaries reflecting their transitions to CEO and Strategic Adviser, respectively.

​ | Adjusted Earnings before interest, tax, depreciation and amortization in dollars (“Adjusted EBITDA$”) | ​ | ​ | Reported net sales minus operating expenses, which includes the cost of sales, research and development expenses and selling and administrative expenses but excludes depreciation and amortization expense, and excludes certain extraordinary and non-operational items, if any, as reported by the company | ​ | ​ | 2021 CIP | ​
​ | Adjusted Earnings before interest, tax, depreciation and amortization as a percentage of net sales (“Adjusted EBITDA%”) | ​ | ​ | Adjusted EBITDA$   divided by net sales | ​ | ​ | 2021 CIP | ​
​ | Total Revenue | ​ | ​ | Reported annual net sales including the impact of foreign currency and divestitures and acquisitions | ​ | ​ | 2021 CIP | ​
​ | Incentive Return on Invested Capital (“Incentive ROIC”) | ​ | ​ | 3-year average of incentive operating profit (net sales minus operating expenses, which includes the cost of sales, research and development expenses and selling and administrative expenses) divided by (total assets — cash — short-term investments) — (total liabilities – debt) | ​ | ​ | 2019–2021 LTIP 2020–2022 LTIP 2021–2023 LTIP | ​
​ | Incentive Cumulative Earnings Per Share | ​ | ​ | 3-year sum of adjusted net earnings divided by weighted average shares outstanding | ​ | ​ | 2019–2021 LTIP 2020–2022 LTIP 2021–2023 LTIP | ​

TABLE OF CONTENTS
The Committee approved the use of Adjusted EBITDA$ and Adjusted EBITDA% as financial metrics for the fiscal 2021 CIP, in addition to Total Revenue, because it believes that these metrics are the most relevant to assess the annual operating and long-term performance of the business with respect to creation of shareholder value.
As used in the above metrics, EBITDA$ and net earnings used in the calculation of Incentive Cumulative Earnings Per Share are adjusted and calculated as reported by the company in the earnings releases for the applicable period. With respect to all plan metrics set forth in the above chart, the Committee has authority to interpret our incentive plans, adjust business results and take other actions in its sole discretion to assure that the plans meet our compensation objectives and appropriately hold executives and other incentive plan participants accountable for our financial results.
Achievement of 2021 CIP
To drive achievement of our growth and financial performance goals, our 2021 CIP metrics were Adjusted EBITDA$, Adjusted EBITDA%, and Total Revenue. In 2021, based on the company’s financial performance against these metrics, the payout level was 122.09% of target.

Performance Measure | ​ | ​ | Weighting | ​ | ​ | Threshold | ​ | ​ | Target | ​ | ​ | Maximum | ​ | ​ | 2021 Actual | ​
Adjusted EBITDA$ (in thousands) | ​ | ​ | ​ | ​ | 50% | ​ | ​ | ​ | ​ | $ | 117,000 | ​ | ​ | ​ | $137,800 | ​ | ​ | $148,000 | ​ | ​ | $140,125 | ​
Adjusted EBITDA% | ​ | ​ | ​ | ​ | 25% | ​ | ​ | ​ | 11.9% | ​ | ​ | 12.9% | ​ | ​ | 13.4% | ​ | ​ | 12.85% | ​
Total Revenue ($ in thousands) | ​ | ​ | ​ | ​ | 25% | ​ | ​ | ​ | $981,000 | ​ | ​ | $1,067,000 | ​ | ​ | $1,107,100 | ​ | ​ | $1,090,772 | ​
Payout Level (% of Target Payout) | ​ | ​ | ​ | ​ | — | ​ | ​ | ​ | 50% | ​ | ​ | 100% | ​ | ​ | 200% | ​ | ​ | 122.09% | ​

For the 2021 CIP, all of the Named Executives targets were weighted 100% on company financial results representing the Committee’s belief that all Named Executives should be driving and be accountable for the overall performance of the company at an enterprise level.
2021 Long-Term Incentive Plan Structure
As shown in the table below, our equity award mix was unchanged from 2020 such that 50% of each Named Executive’s LTI opportunity is delivered in PRSUs with the remaining 50% split evenly between stock options and restricted stock.

​ | ​ | ​ | Equity Award Mix | ​
​ | ​ | ​ | 2020 | ​ | ​ | 2021 | ​
Performance-Based Restricted Stock Units | ​ | ​ | ​ | ​ | 50% | ​ | ​ | ​ | ​ | ​ | 50% | ​ | ​
Stock Options | ​ | ​ | ​ | ​ | 25% | ​ | ​ | ​ | ​ | ​ | 25% | ​ | ​
Restricted Stock | ​ | ​ | ​ | ​ | 25% | ​ | ​ | ​ | ​ | ​ | 25% | ​ | ​

The 2021-2023 PRSU grants are earned on the basis of our performance on Incentive ROIC (weighting of 60%) and Incentive Cumulative Earnings Per Share (weighting of 40%) over a three-year period of 2021 to 2023.
The Incentive ROIC metric is important as it measures the return generated from capital invested and holds us accountable for both profitability and effective use of our balance sheet. We use Incentive Cumulative Earnings Per Share as a metric because of its bottom-line focus on profitability, its multiple levers to drive performance over multi-year periods and because it is a key measure to our investors.
Performance at the threshold level earns a payout equal to 50% of target, while performance at the maximum level earns a payout equal to 200% of target. The performance targets are confidential and competitive information when set, particularly to the extent they relate to projected company financial results, which the company does not publicly disclose. The Committee believes that targeted levels of performance for the LTIP grants are challenging and will not be achieved all the time. The Committee sets the LTIP financial performance target at a level that would make it reasonably difficult to achieve, when considering the business environment at the time the target was established. Under our LTIP methodology,

TABLE OF CONTENTS
financial performance is assessed in relation to the company’s annual operating plan, budgeted invested capital, cumulative earnings per share, and long-range plan.
Under the terms of Tennant Company’s 2020 Stock Incentive Plan, stock options are granted with the exercise set equal to the fair market value the day before the grant is approved by the Committee. Stock options have a 10-year term and vest in one-third (1/3) increments over a 3-year term beginning on the first anniversary of the grant date.
Restricted stock grants to each Named Executive vest 100% on the 3 rd anniversary of the grant date. Dividends are accumulated on restricted stock during the vesting period and paid in cash upon vesting.
Additional information regarding the equity awards we granted in 2021 are included in the Grants of Plan-Based Awards in Fiscal 2021 and the accompanying footnotes.
Achievement of 2019-2021 Performance-Based Restricted Stock Units
In February 2019, the Committee approved the 2019-2021 LTIP for the Named Executives in the following mix:
•
40% PRSUs that vest at the end of the 2019-2021 period based on the performance metrics described below;
​
•
40% non-qualified stock options vesting ratably over three years; and
​
•
20% restricted stock that cliff vests at the end of three years.
​
The 2019-2021 PRSUs were earned on the basis of our performance on Incentive ROIC (weighting of 60%) and Incentive Cumulative Earnings Per Share (weighting of 40%).
Despite the impact that COVID had on our results in 2020 and 2021, the company’s strong performance against these measures resulted in a payout of 112.24% of target.

Performance Measure | ​ | ​ | Weighting | ​ | ​ | Threshold | ​ | ​ | Target | ​ | ​ | Maximum | ​ | ​ | Actual | ​
2019-2021 Incentive ROIC (12-Month Average/3-Year Simple Average) | ​ | ​ | ​ | ​ | 60% | ​ | ​ | ​ | 10.7% | ​ | ​ | 14.3% | ​ | ​ | 15.7% | ​ | ​ | 13.56% | ​
2019-2021 Cumulative Earnings Per Share | ​ | ​ | ​ | ​ | 40% | ​ | ​ | ​ | $6.41 | ​ | ​ | $8.55 | ​ | ​ | $9.40 | ​ | ​ | $8.95 | ​

2020 Long-Term Incentive Plan Structure and Incentive Plan Goal Adjustments
In February 2020, the Committee approved our 2020 LTIP structure for our Named Executives in the following mix which was the same as our 2019 LTIP structure:
•
50% PRSUs that vest at the end of the 2020-2022 period based on the performance metrics described below;
​
•
25% non-qualified stock options vesting ratably over three years; and
​
•
25% restricted stock that cliff vests at the end of three years.
​
As approved by the Committee, the 2020-2022 PRSU grants are earned based on Incentive ROIC (weighting of 60%) and Incentive Cumulative Earnings Per Share (weighting of 40%).
In early 2021, after considering the pandemic’s impact on the 2020 – 2022 PRSU grant, which represented 50% of the total award value for the fiscal 2020 LTI, the Committee adjusted the performance goals for the 2020 – 2022 PRSUs to ensure a continued focus on the achievement of our long-range plan objectives. This adjustment also ensures the grants can continue to meet our compensation objectives of (1) creating a direct link to stock price performance; (2) aligning incentives with key financial drivers of shareholder value; and (3) supporting leadership retention and executive stock ownership. In reaching this decision, the Committee specifically considered several factors:
35

TABLE OF CONTENTS
•
Concerns that the original 2020-2022 PRSU grant reduced management accountability for driving performance results for the remaining two years in the three-year performance cycle as this interim period within our long-range plan was particularly impacted by the pandemic;
​
•
The Committee’s belief that an unprecedented, exogenous event in the first three months of a three-year performance cycle should not result in a complete forfeiture of that award and that our employees should have the opportunity to re-earn that award against a recalibrated set of performance requirements; and
​
•
Our leadership transition and other executive vacancies created management uncertainty. Compensation certainty ensures that PRSU award recipients remain focused on business execution through the pandemic without compensation-related distractions. All employees across the company who participate in our long-term incentive program receive PRSUs and this change applied to all PRSU grants identically.
​
The Committee believed that taking these actions early in the performance period would provide more real-time alignment of objectives and incentives for the remaining two years of the three-year performance cycle, as opposed to waiting until the end of the performance period to assess any appropriate adjustments after the fact.
Under U.S. GAAP, adjustment to the 2020-2022 PRSU goals is considered an accounting modification, and the SEC disclosure requirements mandate that the incremental modification date fair value for this grant be disclosed in certain of the compensation tables as a new grant. As the Committee took this action in 2021, the incremental modification date fair value is included in the Stock Awards column of the Summary Compensation Table for 2021 and as a separate grant in the Grants of Plan-Based Awards in Fiscal 2021 table.
Compensatory Arrangements for CEO Succession
As described above, effective March 1, 2021, Mr. Huml became our CEO, succeeding Mr. Killingstad who previously announced his plans to retire. In February 2021, following review of market data and other information provided by the Committee’s independent compensation consultant, the Committee recommended, and the independent members of the Board approved, compensatory arrangements for Mr. Huml and Mr. Killingstad in connection with their new roles.
Effective March 1, 2021, Mr. Huml’s annual base salary increased to $800,000, his CIP target increased to 100% of base salary, and his LTIP target for his fiscal 2021 awards was 275% of base salary. In addition, the Committee approved an amendment to Mr. Huml’s executive employment agreement to increase his cash severance from 12 to 24 months of base salary and his COBRA continuation coverage from 12 to 18 months in the event his employment terminates under circumstances that would entitle him to severance under circumstances unrelated to a change in control.
The CIP targets for Mr. Huml for fiscal 2021 were based on different target incentive levels and pro-rated based on a different base salary in effect before and after March 1, 2021.
As previously announced, Mr. Killingstad remained with the company in a non-executive capacity as Strategic Adviser to the CEO and Board through December 31, 2021. Effective March 1, 2021, Mr. Killingstad’s annual base salary decreased to $400,000 and his CIP target decreased to 60% of base salary. He received LTIP for fiscal 2021 with a value of $850,000, with approximately one-third of the value granted in stock options and two-thirds of the value granted in restricted stock units, each vesting in full on the second anniversary of the date of grant contingent upon Mr. Killingstad’s continued service through the transition period and compliance with the non-competition and other post-termination covenants in his employment agreement through such period. Once vested, the stock options will remain exercisable until the seventh anniversary of the grant date.
Other Plans and Agreements
Named Executives may also receive payments through various other agreements and the plans described below or in the event of special circumstances. These agreements and plans are typically required in the competitive environment to attract and retain talent.

TABLE OF CONTENTS
Retention, Sign-on, and Other Recognition Awards
In fiscal 2020, in connection with position changes among our Named Executives, Mr. Zay received a cash incentive award valued at $650,000 that was paid out on December 7, 2021, based on his continued employment through that date. This award is disclosed in the Summary Compensation Table. The award was granted to Mr. Zay during fiscal 2020 as an incentive for him to remain with the company through the company’s CEO transition given his important role leading the company’s global regional sales and service business units. This amount was determined based on compensation that Mr. Zay may be entitled to in certain termination of employment situations.
From time to time, the Committee may determine that it is appropriate to provide for certain sign-on awards in order to attract an executive to leave his or her current employment and join the Company. In 2021, the Committee approved certain sign-on compensation for Ms. West in connection with her commencement of employment and relocation. The Committee granted her a cash sign-on bonus in the amount of $100,000 that is subject to repayment, on a pro-rated basis, if Ms. West resigns within one year after she commenced employment, and restricted stock units with a grant date fair value of $1,100,000 that vests as to 50% of the units on each of the first and second anniversaries of the date of grant. In addition, the Committee approved the reimbursement of Ms. West’s relocation expenses in connection with her relocation to Minnesota on or before the end of the summer of 2022, subject to the company’s relocation program, which reimbursement is subject to repayment if Ms. West resigns within two years following such relocation.
Mr. Paulson was compensated for his service as Interim CFO in fiscal 2021 at a rate of $50,000 per month, with a $175,000 cash bonus paid following satisfactory completion of his interim duties.
Retirement Savings Plan
Our Named Executives are generally eligible to participate in the broad-based welfare benefit programs that we sponsor, including the Tennant Company Retirement Savings Plan (“Savings Plan”). The Savings Plan is available to all eligible employees, as defined by the plan, and allows for pre-tax elective deferrals, Roth contributions and a matching contribution by us of up to 3% of eligible compensation up to $290,000. In addition, the Savings Plan allows profit-sharing contributions by us based on the relevant metric set. This additional profit-sharing contribution is paid into each eligible employee’s account under the Savings Plan unless the amount exceeds 3.5% of eligible compensation, in which case 3% is paid into the eligible employee’s account and the balance of the actual calculated profit-sharing amount is paid in cash to the employee. The Adjusted EBITDA$ achieved in 2021 resulted in a profit-sharing contribution of 3.18% of eligible compensation up to $290,000, under the Savings Plan for 2021.
Supplemental Retirement Savings Plan (Non-Qualified Deferred Compensation)
Our Named Executives are eligible for supplemental non-qualified benefits under our Non-Qualified Deferred Compensation Plan. The intention of this plan is to provide participating individuals with benefits that would otherwise be available to them under our Savings Plan but for the application of limitations on benefits imposed by the Internal Revenue Code. The amounts deferred in this plan are listed in the “Excess” column in the All Other Compensation Table which is included as a footnote to the Summary Compensation Table. In addition, this plan allows employee participants to defer the receipt of base salary and CIP payments and non-employee directors to defer receipt of annual retainers as follows:
•
executive officers, including Named Executives, may elect to defer 0 – 25% of their base salary and 0 – 100% of their CIP payout; and
​
•
non-employee directors may elect to defer 0%, 50% or 100% of their annual retainer.
​
The interest rate earned on deferrals in 2021 was 1.9278%.
Certain management and Named Executives may defer income on a pre-tax basis in excess of the deferral amounts allowed under our Savings Plan. Participating employees may receive discretionary company contributions under this plan in the form of excess profit sharing not available to them under the Savings Plan. In addition, participants are eligible to receive matching contributions not available to them
37

TABLE OF CONTENTS
under the Savings Plan. Under the terms of this plan, matching contributions and annual profit-sharing contributions are based on formulas applicable to them in the Savings Plan but not available because of qualified plan limitations. Participants’ accounts are fully vested, at all times, except that a participant forfeits all company discretionary matching contributions and profit-sharing contributions in the event of termination for cause. Pursuant to this plan, “cause” means (i) the participant’s gross negligence, fraud, disloyalty, dishonesty or willful violation of any law or significant policy, to the extent committed in connection with the position or (ii) the participant’s failure to substantially perform (for reasons other than disability) the duties reasonably assigned or appropriate to his or her position. In each case, the participant’s behavior must have resulted in a material adverse effect on our company or an affiliate. The timing of payment of benefits attributable to amounts contributed or deferred after January 1, 2003, including company contributions and gains and losses credited thereon, varies based on the type of contribution or deferral.
Executive Employment Agreements, Management Agreements and Executive Officer Severance Plan
We have entered into Executive Employment Agreements and Management Agreements with Mr. Huml, Mr. Zay, and Ms. McKnight. The Committee has determined that we should enter into these agreements to obtain the benefits of their services and attention to our affairs. In exchange for the benefits we provide under these agreements, the Named Executives are required to agree to certain confidentiality, non-competition and cooperation covenants, which the Committee believes are valuable when an executive’s employment terminates. In addition, the Committee believes that we should provide an inducement for executive officers to remain in our service in the event of any proposed or anticipated change in control in order to facilitate an orderly transition, without placing the executive in a position where he or she is concerned about being terminated without compensation in connection with such a transaction. We also require executive officers to sign a release of their claims against us as a condition to receiving payments from us, and this release and the other covenants are more likely to be enforceable as a result of the benefits we provide under these arrangements. A description of these agreements is included under “Agreements and Arrangements with Named Executives.”
Any executive officer hired or appointed to their role since October of 2018, including Ms. West and Mr. Glusick, participate in the Executive Officer Severance Plan. The key terms governing a separation of an executive officer under the plan are substantially the same as those covering the other Named Executives with a few key differences. A description of the plan is included under “Agreements and Arrangements with Named Executives.” As Interim CFO, Mr. Paulson and Mr. Cebulla were not entitled to severance benefits under an individual agreement or the Executive Officer Severance Plan.
Generally, the arrangements only provide for benefits in the event the executive is terminated without cause, provided that certain benefits are also provided if the executive voluntarily terminates his or her employment for good reason under the agreements. The Committee believes that a termination by an executive for good reason may be conceptually the same as termination by us without cause. This is particularly true in the case of a change in control where a potential acquirer would otherwise have an incentive to constructively terminate the executive’s employment to avoid paying severance benefits. These arrangements are described below under “Agreements and Arrangements with Named Executives.” No cash severance becomes due merely upon a change in control, but rather only if the executive officer’s employment is terminated without cause or if the executive officer terminates for good reason following the change in control, which is often referred to as a “double trigger.”
The form and level of benefits provided under these agreements have been approved by the Committee based on historical practices and general information about the level of benefits provided by other companies with whom we compete for executive talent.
Our equity awards for all employees generally provide for acceleration of vesting, or lapse of restrictions, upon a change in control. The Committee believes that acceleration upon a change in control is appropriate to minimize the risk that executive officers might favor a particular transaction based on the likely impact on the executive officer’s equity awards, to increase the likelihood that the employees will remain with us after becoming aware of a pending or threatened change in control, and due to the increased likelihood that employees may be terminated by a successor through no fault of their own.

TABLE OF CONTENTS
Compensation Policies
Recoupment Policy
We have a recoupment (or claw-back) policy. The policy is applicable to all employees designated as access persons under our insider trading policy (persons with access to detailed financial and other insider information, a group that includes all executive officers). The policy requires recoupment of certain cash and equity incentive award payouts in the event we are required to restate our financial results. The amount subject to recoupment is the amount that would not have been earned or paid based on the restated results. In all cases, any recoupment is based on net proceeds from the awards subject to recoupment and includes the proceeds from the sale of any shares subject to equity awards that are subject to recoupment, as well as any dividends paid on the shares received from an award.
The policy that was amended by our Committee in 2018 now also subjects all cash incentive and equity awards to forfeiture and/or recoupment in the event a covered person engages in certain gross misconduct.
In administering the policy, the Committee has discretion to reduce the amount of any forfeiture or recoupment and may also pursue other remedies against a covered person for conduct covered by the policy.
Executive Officer Stock Ownership Guidelines
To align executive officers’ interests with shareholders’ interests, the Committee expects executive officers to acquire significant equity ownership. The guidelines require that within five years of service in an executive role, each executive must have achieved an equity ownership level equal to a specified multiple of his or her base salary.
The minimum equity ownership levels are five times annual base salary for our CEO and two times annual base salary for the other Named Executives. Ownership levels are calculated based on actual shares owned plus the estimated after-tax value of restricted and unrestricted shares, deferred stock units and shares held under benefit plans, and potential gains from vested options. The calculation uses a stock value as of the close of market on December 31 of the year immediately preceding the year of calculation.
Executive officers who have held executive positions with us for five years or more have achieved their goals. Newer executive officers are on pace for achieving their ownership targets within the five-year period.
Prohibition on Hedging and Pledging
Our insider trading policy prohibits all directors, officers and other employees designated as access persons (as defined under “Recoupment Policy” above), including their family members and designees, from engaging in speculative trading or hedging of positions in our securities, including purchasing any financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) that are designed to hedge or offset any decrease in the market value of any of our equity securities. It also prohibits pledges of any company securities (e.g., pledge to a bank or financial institution as collateral for a loan, or pledge to a broker in connection with a market transaction, such as a margin loan). These prohibitions do not restrict general portfolio diversification transactions or investments in broad-based index funds.
Granting of Equity Awards
We have an equity award approval policy to ensure that all equity awards are approved pursuant to proper authority, follow a consistent process, and are reflected in appropriate documentation. Under the policy, equity awards that have an exercise price or number of shares that are based on the fair market value of our common stock on the date of grant are only granted at times when trading is permitted under our insider trading policy. This policy ensures that the exercise price or number of shares is determined by reference to a stock price that reflects current public information. The policy includes procedures for granting equity awards to executive officers and non-employee directors, as well as all other employees. Under our plans, the exercise price of stock options is based on the fair market value on the date of grant and defines fair market value as the closing price of our common stock on the preceding trading day.

TABLE OF CONTENTS​
Deductibility of Executive Compensation
Due to the enactment of the Tax Cuts and Jobs Act of 2017 in December 2017, compensation paid in fiscal 2019 and later years to any Named Executive in excess of $1 million will not be deductible under Section 162(m) of the Code unless it qualifies for transitional relief applicable to certain binding, written performance-based compensation arrangements that were in place as of November 2, 2017. No assurance can be given that the compensation associated with these awards will qualify for the transitional relief. While the Committee is mindful of the benefit to us of the deductibility, it believes that we should maintain flexibility in compensating our executive officers in a manner that best promotes our corporate objectives.
Compensation Committee Report
The Committee has discussed and reviewed the Compensation Discussion and Analysis with management. Based upon this review and discussion, the Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

Amounts represent the aggregate grant date fair value of the annual restricted stock awards and PRSUs (at target) that were granted in each fiscal year. Grant date fair values are calculated in accordance with FASB ASC Topic 718. See Footnote 18 “Share-Based Compensation” to our consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2021, for the assumptions used in this calculation. The grant date fair value of each restricted stock and RSU award and the targeted grant date value of each PRSU award were computed in accordance with FASB ASC Topic 718 based on the closing stock price on the grant date.
​
Amounts for 2021 also include the incremental grant date fair value related to the adjustment to Incentive ROIC and Incentive Cumulative Earnings Per Share goals for the 2020-2022 PRSU awards based on the modified target, which adjustments were approved in February 2021. The incremental grant date fair value related to the modification was computed in accordance with FASB ASC Topic 718 based on the closing stock price on the date that the goal adjustments were approved. Neither Mr. Paulson nor Mr. Cebulla received any stock awards during 2021 for their Interim CFO service.

Non-Qualified Deferred Compensation in 2021
Two elements of Total Direct Compensation may be deferred: base salary and CIP payouts. Named Executives may elect to defer 0 – 25% of their base salary and 0 – 100% of their CIP payout. The interest rate for 2021 Non-Qualified Deferred Compensation was 1.9278%. This rate is based on the ten-year treasury bond rate as of December 7, 2020, of 0.9278% plus 1%. For additional explanation of our non-qualified deferred compensation plan, see “Compensation Discussion and Analysis — Other Plans and Agreements — Supplemental Retirement Savings Plan (Non-Qualified Deferred Compensation).” Neither Mr. Paulson nor Mr. Cebulla participated in the non-qualified deferred compensation plan in 2021.

Agreements and Arrangements with Named Executives
In October 2018, the Compensation Committee adopted the Executive Officer Severance Plan (the “Severance Plan”) to provide executive officers who subsequently join the company severance benefits following certain termination scenarios. New executive officers participate in the Severance Plan in lieu of entering into separate agreements with the company, a practice which has become less common. The benefits under the Severance Plan are substantially the same as the benefits provided under the existing Executive Agreements (as defined below) with the other Named Executives.
We are a party to agreements with each of the Named Executives other than Ms. West, Mr. Glusick, Mr. Paulson, and Mr. Cebulla that together establish the terms of the employment relationship between the company and the executive, the terms under which that relationship may be ended, and the rights and obligations of the parties after the employment relationship ends. Collectively, these agreements are referred to as the “Executive Agreements” and consist of an Executive Employment Agreement and a Management Agreement. As Interim CFO, Mr. Paulson and Mr. Cebulla were not entitled to severance benefits under an individual agreement or the Executive Officer Severance Plan.
The Executive Agreements address various termination of employment scenarios, including an executive’s involuntary termination without cause, an executive’s voluntary termination for good reason, and an executive’s death or disability. No severance payments are made to executive officers who are terminated for cause. An executive agrees under the Executive Agreements not to compete with the company during employment or for a period of 12 months after employment ends, not to disclose confidential information during or after employment for as long as the information retains its confidential nature, and not to solicit employees or customers for a period of 12 months after employment ends. Severance payments as described below under the Executive Agreements are conditioned on an executive remaining in compliance with these requirements, including an obligation to inform us of any potentially competitive activities during the 12-month post-employment period, and signing a release of claims in favor of the company. The Executive Agreements also provide that severance payments under those agreements will be reduced by the amount of any other severance compensation an executive is eligible to receive from us under any other agreement or plan of ours providing compensation in the event of involuntary termination.
Executive Employment Agreements
The Executive Agreements with the Named Executives describe the rights and obligations of the company and the executive in connection with the executive’s separation from employment in situations other than following or in connection with a change in control. Under the Executive Agreements:
•
Upon any termination of employment, an executive will receive any earned but unpaid base salary and CIP payments for the preceding year.
​
•
Upon a termination due to death or disability, an executive (or beneficiary) will also receive base salary through the last day of the calendar month in which the termination occurs.
​

TABLE OF CONTENTS
•
Upon termination by the company without cause or by the executive for good reason, the executive is entitled to receive (i) an amount equal to one year’s base salary, (ii) an amount equal to a pro-rata portion of the award that would have been payable to the executive under the CIP for the year of termination had the executive been employed for the full year, based on the actual performance of objectives, with such amount before proration not to exceed an award based on target performance, and (iii) benefits continuation for up to 12 months after termination.
​
The timing of the payment of the foregoing amounts is as follows: the executive is paid his or her base salary in accordance with regular payroll practices for a period of 12 consecutive months following the date of termination, provided that if the payment of base salary exceeds the amount that would cause it to be considered a deferral of compensation under Section 409A of the Internal Revenue Code, the excess will be paid in a lump sum within 2 1∕2 months of the termination date; the executive’s CIP payment is made at the normal payment date, but in no event later than 2 1∕2 months after the end of the CIP plan year; and the medical, dental and group life insurance contributions will be paid for a period of up to 12 months after the termination date, unless the executive is no longer eligible for COBRA continuation coverage or fails to timely pay the employee portion of such premiums.
As described above, effective March 1, 2021, Mr. Huml’s Executive Agreement was amended to increase the cash payment he would receive to two year’s base salary and increase his benefits continuation to up to 18 months after termination.
For purposes of the Executive Agreements, “cause” means (i) executive’s material breach of the agreement that is not remedied within 30 days after receiving written notice from us, (ii) an executive’s dishonest act(s) intended to result in gain or personal enrichment at our expense, (iii) an executive’s persistent, willful and deliberate failure to perform his or her duties that constitutes gross neglect and is not remedied within 90 days of receipt of written notice from us, (iv) an executive’s indictment or conviction for a felony if the underlying acts are substantially detrimental to the company or its reputation, or (v) executive’s material violation of any company policy.
For purposes of the Executive Agreements, “good reason” means the occurrence of the following without executive’s consent: (i) material breach of the agreement by the company, or (ii) a material diminution in the executive’s authority, duties or responsibilities other than for cause or on account of disability, provided that in either case the executive gives the notice within 90 days of the first occurrence of the condition and we fail to remedy it within 30 days after receipt of written notice.
Management Agreements
Recognizing the need to retain executive officers if there is a possible change in control, and in order to facilitate an orderly transition in the event of an actual change in control, the Management Agreements with the Named Executives provide for severance compensation if an executive is terminated under certain circumstances after or in connection with a change in control. Under the Management Agreements:
•
If within three years of a change in control an executive is involuntarily terminated without cause or terminates his or her employment for good reason, then change-in-control severance compensation consists of (i) an amount equal to three times the executive’s annual compensation, (ii) a pro-rata payment of the executive’s CIP award for the year of termination, assuming all performance targets had been met, and (iii) an amount equal to 18 times our portion of the monthly premium cost (as of the termination date) for group medical, dental and basic life insurance coverage, to the extent the executive was covered by such plans on the termination date; the foregoing payments will be made in a lump sum within 2 1∕2 months after the termination date.
​
•
If an executive is involuntarily terminated or terminates his or her employment for good reason prior to an event that would otherwise constitute a change in control, such termination is in connection with or in anticipation of a change in control, and a change in control ultimately occurs, then change-in-control severance compensation will be payable consistent with the first bullet point above, except that the severance pay will be paid within 2 1∕2 months after the change in control.
​
•
If an executive’s employment is terminated due to death or disability, the executive (or beneficiary) will receive base salary paid through the end of the month in which termination occurs.

TABLE OF CONTENTS
In connection with his retirement as CEO, pursuant to the terms of his transition letter agreement, Mr. Killingstad was not entitled to any benefits under the Management Agreement after March 1, 2021.
For purposes of the Management Agreements, “cause” is defined more narrowly than under the Executive Agreements and means (i) an executive’s persistent, willful and deliberate failure to perform his or her duties that constitutes gross neglect and is not remedied within 90 days of receipt of written notice from us, or (ii) an executive’s indictment or conviction for a felony if the underlying acts are substantially detrimental to the company or its reputation.
For purposes of the Management Agreements, “good reason” is defined more broadly than under the Executive Agreements and includes the following in addition to the factors cited in the Executive Agreements: (i) the executive’s duties, responsibilities, or authority are materially diminished as compared to his or her duties, responsibilities, or authority before the change in control, for reasons other than cause or disability, including, but not limited to, a material reduction in the executive’s budget authority or number of direct reports or executive’s removal from any position or office held, (ii) a material reduction in the executive’s base salary or target incentive opportunity, (iii) a material reduction in the authority, duties, or responsibilities of the person to whom the executive reports, (iv) any successor fails to assume the Management Agreement, (v) the executive is required to relocate to any place other than a location within 25 miles of the location at which the executive performed duties immediately prior to the change in control, or (vi) the executive is required to travel on company business to a substantially greater degree than required immediately prior to the change in control. For good reason to exist, the executive must give the company notice within 90 days of the first occurrence of the good reason condition, we must fail to remedy it within 30 days after receipt of written notice, and the executive must resign within six months following the date the executive provided written notice.
For purposes of the Management Agreements, “annual compensation” means (i) the executive’s highest annual base salary rate, as established by the company, in effect during the term of the Management Agreement, plus (ii) the higher of (a) the executive’s target short-term incentive plan award for the plan year that includes the termination date or (b) the average short-term incentive plan award payable to the executive by the company for the three full plan year period ending immediately prior to the plan year that includes the termination date (or the entire period that the executive participated in the short-term incentive plan, if less than three full plan years). For this purpose, annual compensation is calculated prior to any deductions for any elective deferrals the executive may have made to a deferred compensation plan of the company.
For purposes of the Management Agreements, “change in control” means (i) 50% or more of directors are individuals who were not appointed by the Board to fill vacancies on the Board or were not supported by the Board for election by shareholders or were elected or appointed by the Board in connection with an actual or threatened proxy contest, (ii) 35% or more of common stock or of the voting power of securities generally is acquired or beneficially owned by an individual, entity or group (subject to certain exceptions for certain affiliates and employee benefit plans), (iii) we consummate a merger with or into another entity, unless the voting securities of the surviving entity are more than 50% controlled by shareholders prior to the merger and in substantially the same proportions, and no individual, entity or group beneficially owns more than 35% of the surviving entity, (iv) we consummate an exchange of voting securities for cash, securities or other property, unless shareholders receive in the exchange voting securities of a parent corporation that are more than 50% owned by shareholders prior to the exchange in substantially the same proportions, and no individual, entity or group beneficially owns more than 35% of the parent corporation, (v) we consummate a sale or other disposition of all or substantially all of our assets, (vi) shareholders approve a definitive plan to liquidate or dissolve the company, (vii) the company enters into an agreement relating to a change in control as described in clauses (i) through (v) above and such change in control occurs within two years of such agreement, or (viii) a tender or exchange offer or proxy contest is commenced that results, within two years, in a change in control described in clauses (i) or (ii) above.
Change-in-control severance compensation under the Management Agreements, as well as any other compensation under other plans or agreements that are contingent upon a change in control, may be reduced to the extent necessary to avoid excise taxation to the executive and non-deductibility to the company under federal income tax laws applicable to “parachute payments.”

TABLE OF CONTENTS​
Executive Officer Severance Plan
The Severance Plan provides eligible executive officers severance benefits following certain termination scenarios before or after a change in control of the company. Ms. West and Mr. Glusick are participants in the Severance Plan but are not parties to the Executive Agreements described above.
The benefits for an executive officer under the Severance Plan for a separation from employment in situations other than following or in connection with a change in control are substantially the same as those benefits provided to the Named Executives under the Executive Agreements described above except that there is no benefit provided for good reason employment separations. The benefits for an executive officer under the Severance Plan for a separation from employment under certain circumstances after or in connection with a change in control include a lump-sum cash payment equal to two times the executive officer’s annual compensation, which is less than the three times annual compensation amount provided under the Executive Agreements, as well as other severance benefits that are substantially the same as those benefits provided under the Executive Agreements described above.
With respect to addressing any potential parachute payments subject to Section 280G of the Internal Revenue Code, the Severance Plan includes a “net best” provision providing that the amount of any severance payments and benefits that the executive otherwise would be entitled to receive would be reduced to the extent necessary to avoid the excise tax under the Internal Revenue Code, but only if such reduction would result in the executive retaining a greater amount of such payments and benefits on an after-tax basis than had no reduction been made.
Equity Plan and Award Agreement Acceleration Provisions
Our equity-based incentive plans and the award agreements under those plans also call for compensation to be provided under certain circumstances in connection with an executive officer’s termination of employment or a change in control. Our equity incentive plans allow for acceleration of stock options upon an executive’s death, disability or retirement and upon a change in control. Upon death or disability, options generally become exercisable in full, and may be exercised at any time, or from time to time, within five years of the executive’s date of death or date of termination due to disability. Upon retirement, options generally become exercisable in full and may be exercised within three months of the date of the executive’s retirement, or if the executive has given the company at least six months’ prior written notice of such retirement, within five years of the executive’s date of retirement. For purposes of our equity compensation plans, “retirement” is generally defined as (i) termination on or after age 55, provided that the executive has been employed by the company or its affiliates for at least ten years, or (ii) termination of employment on or after age 62. Upon a change in control, options generally become exercisable in full, subject to our right to cash out the options by paying the spread.
The plans generally allow for a pro-rata portion of any restricted stock units to be paid out upon an executive’s death, disability or retirement. For time-based restricted stock units the executive, or his or her successor, shall be entitled to the number of units under outstanding awards, pro-rated for the portion of the term of the awards during which the executive was employed. With respect to performance-based restricted stock units, the payment is based on the extent to which achievement of performance targets were satisfied at the end of the performance period and pro-rated for length of employment within the performance period. Upon a change in control, restricted stock units will immediately vest and be paid in full, with PRSUs vesting at the target level.
A pro-rata share of restricted stock is generally payable upon the executive’s death, disability or retirement. The executive, or his or her successor, shall be entitled to the number of shares of restricted stock under outstanding awards, pro-rated for the portion of the term of the awards during which the executive was employed. All restrictions are lifted with respect to such pro-rated shares. Upon a change in control, restricted stock will immediately vest in full.
Potential Payments upon Termination or Change in Control
Assuming that a termination event or change in control occurred on December 31, 2021, the total compensation that would have been payable pursuant to the Executive Agreements or the Severance Plan,

TABLE OF CONTENTS​​
Pay Ratio
As required under and calculated in accordance with Item 402(u) of Regulation S-K, we have determined a reasonable estimate of the ratio of the annual total compensation of Mr. Huml, our President and Chief Executive Officer as of the end of the fiscal year, to the median of the annual total compensation of all employees excluding Mr. Huml for 2021 is 87:1. This ratio was calculated as described below using the median of annual total compensation of all employees, other than Mr. Huml, of $51,033 and the annualized total compensation of Mr. Huml had he been CEO for the entire year is $4,436,367. Mr. Huml’s annualized compensation is based on the following:
•
Salary: his CEO-level salary rate of $800,000 as if such rate had been in effect throughout the entire fiscal year;
​
•
Short-term Cash Incentive (CIP): an annual award of $976,720, which reflects the award that would have been paid had Mr. Huml served in the CEO role for the full year at his CEO salary and CEO STIP target;
​
•
Long-term Incentive (LTIP): the full value of his long-term incentive awards granted in fiscal 2021; and
​
•
All Other Compensation: as reported in the Summary Compensation Table.
​
The annual total compensation for our median employee was calculated in accordance with the rules applicable to the Summary Compensation Table. The SEC rules for identifying the median-compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios. Although allowed under the SEC requirements, we have not excluded any other employees from the calculation.
Our median employee for 2021 was identified from among our active employee population as of October 1, 2021. For our consistently applied compensation measure (“CACM”), we used annualized base salary plus overtime plus shift differentials, which reflects a change from prior years when we used only annualized base salary, to simplify our data calculation efforts. We did not apply any cost-of-living adjustment or differential to the CACM. Compensation paid in currencies other than U.S. dollars was converted to U.S. dollars based on average exchange rates for the 12-month period ended September 30, 2021. We then rank ordered the employee population using our CACM to identify the median employee. We then calculated the identified median employee’s annual total compensation for 2021 of $51,033 in accordance with the SEC rules.

ITEM 3 — ADVISORY APPROVAL OF EXECUTIVE COMPENSATION
As required by Section 14A of the Exchange Act, we seek non-binding advisory approval on executive compensation.
Our compensation philosophy is to maintain programs that will attract, retain, motivate and reward high-caliber key executive officers who can create long-term financial success for the company and enhance shareholder return. The Compensation Committee bases its executive compensation decisions on the following core objectives:
•
align executive compensation with our short- and long-term goals and the interests of our shareholders;
​
•
correlate compensation with performance; and
​
•
provide a comprehensive compensation package that is competitive with those of similarly sized U.S. durable goods manufacturing companies.
​
We believe that our long-standing executive compensation programs have been effective at motivating the achievement of strong results even during challenging economic times, creating a relationship between pay and performance and aligning the interests of executive officers with those of our shareholders while discouraging risk-taking behavior that would be likely to have a material adverse effect on the company.
Shareholders are encouraged to read the “Compensation Discussion and Analysis” and associated compensation tables for a more detailed discussion of how our compensation programs reflect our overarching compensation philosophy and objectives.
We are presenting shareholders with the opportunity to submit an advisory approval on the executive compensation program for Named Executives by voting on the following resolution:

​ | “RESOLVED, that the shareholders of Tennant Company approve, on an advisory basis, the compensation paid to the company’s Named Executives as disclosed in the “Compensation Discussion and Analysis” section, and compensation tables and narrative discussion contained in the “Executive Compensation Information” section in this Proxy Statement.” | ​

This advisory approval will not be binding on the Compensation Committee or the Board. However, they will carefully consider the outcome of the vote. If there are a significant number of negative votes, we may seek to understand the concerns that influenced the vote and consider them in making future decisions about executive compensation arrangements.
The Board of Directors, upon recommendation of the Compensation Committee, unanimously recommends a vote FOR the advisory resolution approving the compensation of the company’s Named Executives.

The Board adopted a written related-person transaction approval policy, which sets forth our policies and procedures for the review, approval or ratification of certain related-person transactions. This policy applies to any transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships in which we are a participant and in which a related person has a direct or indirect interest, but exempts the following:
•
payment of compensation by us to a related person for the related person’s service to us in the capacity or capacities that give rise to the person’s status as a “related person” ​(provided such compensation was approved by the Board or a committee thereof, if such approval was required);
​
•
transactions available to all employees or all shareholders on the same terms; and
​
•
transactions which, when aggregated with the amount of all other transactions between the related person and the company, involve less than $120,000 in a fiscal year.
​
Our Board must approve any related-person transaction subject to this policy before commencement of the related-person transaction or, if the transaction is not identified prior to its commencement, the transaction must be submitted to the Board for ratification. The Board will analyze the following factors, in addition to any other factors the Board deems appropriate, in determining whether to approve a related-person transaction:
•
whether the terms are fair to the company;
​
•
whether the transaction is material to the company;
​
•
the role the related person has played in arranging the related-person transaction;
​
•
the structure of the related-person transaction; and
​

The Board may, in its sole discretion, approve or deny any related-person transaction. Approval of a related-person transaction may be conditioned upon the company and the related person taking such precautionary actions as the Board deems appropriate.
