Proposal 1 — Election of Class III Directors

COMMAND=ADD_TABLEWIDTH,"100%" User-specified TAGGED TABLE

The nominees for election as Class III Directors at the 2021 annual meeting are described below. The Board has nominated each of the candidates for election. If elected, each of the nominees is expected to serve for a three-year term expiring at the annual meeting of stockholders of the Company in 2024 and until their respective successors have been elected and qualified. The Board of Directors recommends a vote FOR the Company's nominees for Class III Directors.

end of user-specified TAGGED TABLE

Our Board of Directors is divided into three classes, with each class serving a consecutive three-year term. The term of the current Class III Directors will expire on the date of the 2021 annual meeting, subject to the election and qualification of their respective successors. The Board of Directors expects that each of the nominees will be available for election as a director. However, if by reason of an unexpected occurrence, one or more of the nominees is not available for election, the persons named in the form of proxy have advised that they will vote for such substitute nominees as the Board of Directors may nominate.

In selecting director candidates, the Nominating and Corporate Governance Committee considers whether the candidates possess the required skill sets and fulfill the qualification requirements of directors approved by the Board of Directors, including integrity, objectivity, sound judgment, leadership, and diversity in all aspects of that term, including differences of perspective, professional experience, education, skills, and other individual qualities, such as gender, race, and ethnicity.

The following table provides the composition of each of our committees:

Board of Directors Independence Standards for Directors

Pursuant to our Corporate Governance Guidelines and Principles, a copy of which is available on our website at www.generac.com , the Board of Directors is required to affirmatively determine whether our directors are independent under the listing standards of the New York Stock Exchange (" NYSE "), the principal exchange on which our common stock is traded.

COMMAND=ADD_TABLEWIDTH,"100%" User-specified TAGGED TABLE

During its annual review of director independence, the Board of Directors considers all information it deems relevant, including without limitation any transactions and relationships between each director or any member of his or her immediate family and the Company and its subsidiaries and affiliates. The Board of Directors also considers the recommendations of the Nominating and Corporate Governance Committee, which conducts a separate independence assessment of all directors as part of its nomination process for the Board of Directors and its respective committees. The purpose of this review is to determine whether any such relationship or transaction is considered a "material relationship" that would be inconsistent with a determination that a director is independent. The Board of Directors has not adopted any "categorical standards" for assessing independence, preferring instead to consider all relevant facts and circumstances in making an independence determination including, without limitation, applicable independence standards promulgated by the NYSE.

ZARCONE | ​ | The audit committee, among other things, assists the Board of Directors in fulfilling its responsibility relating to the following: • the integrity of our financial statements, • our systems of internal controls and disclosure controls and procedures, • our compliance with applicable law and ethics programs, • the annual independent audit of our financial statements, and • the evaluation of financial and enterprise risks, including areas related to legal compliance and ethics, cybersecurity, and certain other functional areas. The Board has determined that each of Messrs. Lampereur, Ramon, Dixon, and Zarcone is an "audit committee financial expert" as defined in Item 407(d)(5) of Regulation S-K, and the Board is satisfied that all members of our Audit Committee have sufficient expertise and business and financial experience necessary to effectively perform their duties as members of the Audit Committee. In connection with its review of the Company's financial statements, the Audit Committee receives reports from the Company's Chief Financial Officer and the Company's independent registered public accounting firm regarding significant risks and exposures and assesses management's steps to minimize them. The Audit Committee also reviews material legal and regulatory matters and compliance with significant applicable legal, ethical, and regulatory requirements, and receives reports from the Company's General Counsel relating to these matters. |

In discharging its duties, the Audit Committee has the sole authority to select, retain, oversee, and terminate, if necessary, the independent registered public accounting firm, review and approve the scope of the annual audit, review and pre-approve the engagement of our independent registered public accounting firm to perform audit and non-audit services, meet independently with our independent registered public accounting firm and senior management, review the integrity of our financial reporting process, and review our financial statements and disclosures and certain SEC filings and financial press releases.

The Audit Committee formally met ten (10) times in 2020, and members of the Audit Committee also met informally among themselves, with management and with other members of the Board from time to time. Decisions regarding audit-related matters were approved by our Board after taking into account the recommendations of the Audit Committee and its members.

The Compensation Committee has decision-making authority with respect to all compensation decisions for our executive officers, including annual incentive plan awards and grants of equity awards. The Compensation Committee is responsible for finalizing and approving the performance objectives relevant to the compensation of our CEO and other executive officers.

The Compensation Committee's recommendations are developed with input from our CEO and, where appropriate, other senior executives. The Compensation Committee reviews management recommendations and input from compensation consultants, along with other sources of data when formulating its independent recommendations to the Board of Directors. A discussion and analysis of the Company's compensation decisions regarding the executive officers named in the Summary Compensation Table appears in this proxy statement under the heading "EXECUTIVE COMPENSATION—Compensation Discussion and Analysis."

To assist it in performing its duties, the Compensation Committee has the authority to engage outside consulting firms. The Compensation Committee has engaged Willis Towers Watson & Co. ("Willis Towers Watson") as its independent compensation consultant since September 2014. In its capacity as outside and independent compensation consultants, Willis Towers Watson reports directly to the Compensation Committee.

The Compensation Committee has sole authority to replace compensation consultants retained from time to time, and to hire additional Compensation Committee consultants at any time.

Criteria for Director Nominees

In selecting director candidates, the Nominating and Corporate Governance Committee considers whether the candidates possess the required skill sets and fulfill the qualification requirements of directors approved by the Board of Directors, including integrity, objectivity, sound judgment, leadership and diversity in all aspects of that term, including differences of perspective, professional experience, education, skills, and other individual qualities, such as gender, race, and ethnicity. Annually, the Nominating and Corporate Governance Committee assesses the composition of the Board of Directors, including the Committee's effectiveness in balancing the above considerations.

CORPORATE GOVERNANCE

Other than the foregoing, there are no minimum criteria for director nominees, although the Nominating and Corporate Governance Committee may consider such other factors as it may deem are in the best interests of the Company and its stockholders. The Nominating and Corporate Governance Committee does not assign specific weights to, and a potential or incumbent director will not necessarily satisfy all of, the foregoing criteria and in evaluating a candidate does not distinguish on the basis of whether the candidate was recommended by a stockholder. Nothwithstanding the foregoing, in furtherance of the Committee's commitment to increasing diversity within the Board of Directors, the Committee has determined that a focused effort to identify director candidates from underrepresented minority groups will be an important consideration and priority in selecting and nominating director candidates for election as future openings become available on the Board of Directors.

Process for Identifying and Evaluating Director Nominees

The Nominating and Corporate Governance Committee identifies nominees by first evaluating the current members of the Board of Directors willing to continue in service. Current members of the Board of Directors with skills and experience that are relevant to the Company's business and who are willing to continue in service are considered for renomination, balancing the value of continuity of service by existing members of the Board of Directors with that of obtaining a new perspective on the Board. If any member of the Board of Directors does not wish to continue in service or if the Nominating and Corporate Governance Committee decides not to renominate a member for reelection, the Nominating and Corporate Governance Committee identifies the desired skills and experience of a new nominee based on the criteria listed above. Current members of the Nominating and Corporate Governance Committee and Board of Directors are polled for suggestions as to individuals meeting the criteria of the Nominating and Corporate Governance Committee. Executive search firms may also be retained to identify qualified individuals. Shareholders who wish to recommend a candidate for consideration by the Nominating & Corporate Governance Committee may do so by sending the candidate's name and supporting information to Mr. Robert Dixon, Nominating & Corporate Governance Committee Chair, c/o Raj Kanuru, Executive Vice President, General Counsel, & Corporate Secretary, Generac Power Systems, Inc., S45 W29290 Highway 59, Waukesha, Wisconsin 53189.

Stockholder Nominations

Our Bylaws contain provisions which address the process by which a stockholder may nominate an individual to stand for election to the Board of Directors at the Company's annual meeting of stockholders. To make a nomination for election to the Board of Directors, a stockholder must submit his or her nomination by providing the person's name and appropriate background and biographical information by writing to the Nominating and Corporate Governance Committee at Generac Holdings Inc., Attn: Raj Kanuru, Executive Vice President, General Counsel, and Secretary, S45 W29290 Hwy 59, Waukesha, Wisconsin 53189. A stockholder's nomination must be received by the Company's Secretary (i) no later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the first anniversary of the previous year's annual meeting of stockholders, (ii) in the event the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered not earlier

A stockholder nomination must be accompanied by the information required by the Bylaws with respect to a stockholder director nominee.

We may require any proposed nominee to furnish other information as we may reasonably require to determine the eligibility of the proposed nominee to serve as a director of the Company. See "PROPOSALS BY STOCKHOLDERS" for the deadline for nominating persons for election as directors at our 2022 annual meeting of stockholders.

Board of Directors Role in Risk Oversight

Our Board and management continually monitor the material risks facing our Company, including financial risk, strategic risk, operational risk, and legal and compliance risk. Management regularly reports to the Board on its activities in monitoring and mitigating such risks. Overall responsibility for risk oversight rests with our Board. In addition, the Board may delegate risk oversight responsibility to a particular committee in situations in which the risk falls within the committee's area of focus or expertise. Our Board believes that for certain areas of risk, our Company is better served by having the initial risk evaluation and risk monitoring undertaken by a subset of the entire Board that is more focused on the issues pertaining to the particular risk. For instance, our Compensation Committee assists the Board in evaluating risks relating to our compensation policies and procedures. Also, our Audit Committee assists the Board in fulfilling the Board's oversight responsibility relating to the evaluation of financial and enterprise risks, including information security, environmental, health & safety, product regulatory, and social matters. As it deems necessary and on at least an annual basis, the respective committee to which oversight and monitoring of a particular risk has been assigned reports on risk exposures and mitigation strategies with respect to such risk to the entire Board.

COMMAND=STYLE_ADDED,"margin-left:11.0pt;text-indent:-11.0pt;" 2020 was another record year for Generac....

First and foremost, we want to highlight the Company's response to the COVID-19 pandemic, as we're extremely proud of our team's efforts in responding to the crisis as we focused on maintaining our operations to the fullest extent possible. This was particularly important considering that our products and services are both essential and critical to help keep a variety of networks and infrastructure up and running, including hospitals, health-care clinics, 911 call centers, and wireless networks. Equally as important, we accomplished this while at the same time implementing a wide range of preventative measures to address the health, safety and well-being of our employees, customers, suppliers, and the communities across the world where we operate and do business.

Through the tireless execution of our nearly 7,000 employees globally during 2020, Generac achieved another year of record financial results across the board, as several metrics far exceeded the previous record levels seen for the full-year 2019. Revenue grew 13% for the full-year to a $2.5 billion, with gross margin expanding 230 basis points to 38.5% and Adjusted EBITDA coming in at $584 million, an expansion of 290 basis points in Adjusted EBITDA margin to 23.5%.

free cash flow during the year. No adjustments were made to our financial targets or design of our Annual Performance Bonus Plan as a result of the COVID-19 pandemic.

In addition to the strong financial performance, the Company had some key accomplishments during the year that are important to the execution of our strategy.

Our ability to execute on the step-function increase in demand for residential products that has emerged from the new "Home as a Sanctuary" mega-trend was an important accomplishment during 2020. In addition, the building out of our Clean Energy market opportunity with the significant ramp in shipments of PWRcell energy storage systems was a key highlight. We also expanded our product and services portfolio with the acquisitions of Energy Systems, our industrial distributor located in Northern California, and Mean Green, a leading manufacturer of an innovative line of battery-powered turf care products. We also made the strategic acquisition of Enbala Power Networks, which enables our entrance into the developing market for grid services. We launched important new products during the year with the introduction of the 24kW home standby generator, the market's most powerful air-cooled unit with built-in energy monitoring. We also introduced the industry's largest rich-burn industrial natural gas generator at 1 MW of output, allowing us to target new market opportunities. All of these key accomplishments, as well as our execution on a number of other strategic initiatives, enabled us to make important progress on our continuing evolution to an energy technology solutions company. Our 2020 record performance provides us with tremendous momentum as we head into 2021.

  • A full discussion of our use of non-U.S. generally accepted accounting principles measures to provide a baseline for evaluating and comparing our operating results, and a reconciliation of Adjusted EBITDA to net income can be found in Item 6 of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Our compensation program is designed to balance rewards for corporate, business and individual results.

The program's strong pay-for-performance alignment is an important part of our continuing commitment to enhancing long-term stockholder value.

We also believe that stockholders are best served when we are able to attract and retain high caliber executive talent. To that end, we offer competitive base salary, as well as annual and long-term incentive opportunities, which encourage specific performance and reward the

To achieve these objectives, we have structured a compensation program that provides our executives with the following:

Pay Element — ​ Form — ​ Purpose — ​
Base Salary Cash (Fixed) Reflects position responsibilities, competitive market rates, strategic importance of the position and individual experience.

Long-Term Incentives Equity (Variable) Rewards strong performance with incentives that focus our executive team on creating stockholder value over the long-term. Performance share weighting adjusted to support our pay for performance philosophy.

The total direct compensation of our executives is market-based, and a significant portion of that compensation, including annual bonus and long-term incentives, is also performance-based. The Compensation Committee believes this construct results in a fair level of pay for target performance, and an above-market opportunity if the executive team builds share value in a sustainable way. We target cash compensation (base salary and annual bonus) around the median of our market and compensation peer group, taking into account the relative responsibilities of our executives. In general, we target long-term incentives at or above the market median to encourage the sustainability of the business and drive long-term stockholder value creation. This aligns with our approach to long-term financial goal-setting in which the Company often sets performance goals above the median, and in some cases above the

Role of the Compensation Committee and Management

The Compensation Committee, composed solely of independent directors, is responsible for making executive compensation decisions for the named executive officers. The Compensation Committee works closely with its independent compensation consultant and management to examine pay and performance matters throughout the year.

Each year, the CEO and CFO establish a budget, which is approved by the Board of Directors. The budget establishes financial targets and other performance-related goals, which gives the Compensation Committee a basis for approving financial targets under the annual incentive plans for the year. The Compensation Committee also reviews the basis for establishing goals and objectives related to the compensation of the named executive officers. During this review, the Compensation Committee considers the balance between short-term cash compensation and long-term incentives and evaluates alignment of pay for performance in

light of established goals and objectives. The Compensation Committee also considers profitable growth of the business and our relative stockholder return. The Compensation Committee sets the CEO compensation based on that evaluation using market and peer group data to determine appropriate total direct compensation levels (consisting of base salary, annual bonus and long-term incentives). The Compensation Committee also reviews and approves compensation for all executive officers using market data and in conjunction with recommendations from the CEO and EVP, Human Resources. See "Assessing External Market Practice" below for more information. Finally, in making subjective evaluations of the overall performance of the CEO, the Compensation Committee considers performance from the perspective of our core values and our leadership principles, which include practicing integrity, driving innovation, demonstrating agility, operational excellence, developing our employees, and building a team environment.

The CEO and EVP, Human Resources also provide the Compensation Committee with additional analyses and recommendations related to compensation of the CFO and all other executive direct reports to the CEO. The annual analysis includes market compensation data and a review of factors such as industry knowledge, level of experience, and skill set as to the compensation of the named executive officers. Neither the CEO nor the EVP, Human Resources makes recommendations with respect to his or her own compensation.

The Role of the Independent Consultant

In 2020, Willis Towers Watson provided advice to the Compensation Committee regarding base pay, use of peer group data, benchmarking of unique job scopes, annual and long-term incentive design, and the CEO pay ratio along with a variety of other compensation-related topics. The Compensation Committee has assessed the independence of Willis Towers Watson pursuant to the SEC rules and concluded that no conflict of interest exists that would prevent Willis Towers Watson from independently advising the Compensation Committee.

Assessing External Market Practice

Attracting and incentivizing high caliber executive talent is a critical part of our compensation philosophy and leadership strategy. Therefore, integral to our approach for setting compensation levels is ensuring we have a competitive pay framework. In support of this objective, annually Willis Towers Watson provides the Compensation Committee with compensation data with respect to similarly sized manufacturing companies in the identified peer group and amongst similarly sized general industry companies from a published survey perspective. In 2020, the Compensation Committee considered both of these sources in determining competitive total direct compensation benchmarks for our CEO, CFO and for the EVP, Industrial NAM. Published industry specific market survey data was considered in determining market total direct compensation benchmarks for all other executive officers. The Compensation Committee has generally targeted the market median for total cash compensation of our named executive officers, with the opportunity to meet or exceed market median if the Company achieves outstanding financial performance in a particular year. The Committee has targeted long-term incentive grant values at or above market median, which may result in total direct compensation at or above the market median with outstanding financial performance.

Peer group membership is also reviewed annually. In 2020 the Compensation Committee engaged Willis Towers Watson to evaluate the peer group to ensure alignment with the company's strategy in light of recent growth, as well as acquisitions in the clean energy industry. Following the review, the Compensation Committee approved changes to remove five companies. The five included Brady Corporation, EnPro Industries, Inc. and Graco Inc. due to business model misalignment, Enerpac Tool Group Corp. due to revenue size and Briggs & Stratton Corporation due to bankruptcy and subsequent transition to private ownership. The Compensation Committee also approved the addition of four new companies, including EnerSys, First Solar, Inc. Resideo Technologies, Inc., and SolarEdge Technologies Inc., each of which focus on storage, alternative power or home energy management. All four are within Generac's revenue range and are aligned with Generac's Clean Energy efforts and strategic direction.

EXECUTIVE COMPENSATION

In March 2020, the Compensation Committee increased Mr. Jagdfeld's Target Bonus from 112.5% to 115% to further align his pay to market competitive levels. For 2020, Adjusted EBITDA (excluding the impact of acquisitions that occurred during the performance period and before deduction for noncontrolling interests) was retained as one of two financial metrics of the AIP. Primary Working Capital ("PWC") as % of net sales replaced Operating Free Cash Flow as the second metric. Individual performance goals ("IPG"), the third and non-financial metric, did not change. The weighting of the metrics remained the same as summarized below:

COMMAND=STYLE_ADDED,"margin-left:11.0pt;text-indent:-11.0pt;" 2020 Annual Performance Bonus Plan Results

The 2020 financial targets for Adjusted EBITDA and PWC were $476.8 million and 27.5%, respectively. IPG goals for named executive officers for 2020 were based on achieving these financial targets, growing the Company's portion of the residential market, increasing industrial market share, geographic expansion (organic and inorganic), and other goals related to growth of our Clean Energy business, product development, organizational development & succession planning.

Achievement of the above stated financial targets under the plan would result in a 100% payout for three components in the plan. For 2020 under the AIP, the Company's Adjusted EBITDA (excluding the impact of acquisitions that occurred during the performance period and before deduction for noncontrolling interests) was $585 million, which exceeded the target for the Adjusted EBITDA portion. The level of Adjusted EBITDA achieved also corresponds to the resulting payout opportunity for the IPG portion of the bonus plan. The IPG is adjusted for each named executive officer's performance against certain defined and measurable goals established at the commencement of the year and developed to achieve specific initiatives related to the Company's longterm strategy. The Company's PWC, also excluding the impact of acquisitions, was 27.1%, which slightly exceeded the target for the PWC portion. As a result, the Committee approved the overall 2020 achievement payout of 182% out of a maximum of 200%.

end of user-specified TAGGED TABLE

  • Adjusted EBITDA under the AIP excludes the impact of acquisitions that occurred during the performance period and is calculated before deduction for noncontrolling interests.

The Compensation Committee maintains its discretion to make adjustments to the annual performance bonuses, regardless of the outcome under incentive bonus formulas. For 2020 the Compensation Committee made no adjustments or modifications to the financial targets or payouts as a result of the COVID-19 pandemic.

Generac believes that equity awards and other forms of long-term incentive compensation are a critical component of a competitive, comprehensive executive compensation program.

Consequently, the Company has made annual equity awards to its named executive officers since 2012.

Our long-term incentive program ("LTIP") is designed to reward our executives for their contribution to the Company's long-term growth and performance, and to better align the interests of our named executive officers with those of our stockholders. In addition, our long-term awards are used to attract and retain critical employee talent by providing a competitive market-based opportunity.

In 2019 and prior, a combination of stock options, restricted stock and performance share awards were granted to the named executive officers, as follows:

In addition, the Compensation Committee approved certain incremental equity awards to be granted to Mr. Minick effective March 1, 2021. The equity awards included an award of restricted stock valued at $1 million that vests on March 1, 2024, and an award of performance shares valued at $1 million, at target achievement level, with a performance period ending December 31, 2023. These awards are intended to retain and align Mr. Minick's interests with certain objectives related to Generac's Energy Technology initiatives over the next three years.

The named executive officers held performance shares granted in 2018 that vested based on results during the three-year 2018-2020 performance period. This grant was intended to encourage target revenue growth measured in compound annual growth rate ("CAGR") and target Adjusted EBITDA margin percentages for 2018-2020. Specifically, if revenue growth (CAGR) and average Adjusted EBITDA margin percentages during the period were achieved within a defined target range on a performance matrix, the named executive officers would earn from 10% to 200% of their target performance share awards. The revenue growth (CAGR) and Adjusted EBITDA margin targets were set at a level, given business conditions at the time the awards were granted, that were designed to be challenging but achievable with strong management performance. After the conclusion of the three-year period, the performance share targets were measured against actual financial results for Generac Power Systems, Inc., excluding any businesses acquired during the three-year period. For the three-year period from 2018-2020, the Committee determined and approved a final vesting of 200%. The minimum, target, and maximum financial performance metrics and the actual results for the 2018-2020 performance awards are reflected below:

Effective April 2019, the Company adopted a formal "clawback" policy applicable to annual and longterm incentive awards made to the CEO, CFO and other executive officers. In December 2020, an amendment expanded the policy to include any other key member of executive management as identified by the board or CEO. Under this policy, the Company may seek to recoup incentive compensation paid to its executive officers to the extent that such compensation was granted, vested, or earned based on financial results that the Company is required to restate as a result of material noncompliance with any financial reporting requirement under federal securities laws.

In addition, under our insider trading policy, officers, employees, and members of the Board of Directors may not engage in short-selling Company common stock at any time. Such individuals are also prohibited from pledging Company securities, including holding Company securities in a margin account, and from engaging in hedging transactions. The prohibition on hedging transactions covers all officers, employees and members of the Board of Directors, and their designees, and prohibits the purchase of any financial instruments (including prepaid

COMMAND=STYLE_ADDED,"margin-left:11.0pt;text-indent:-11.0pt;" Stock Ownership Guidelines

The Compensation Committee believes that it is in the best interest of Generac and its stockholders to align the financial interests of the Company's officers and directors with those of Generac's stockholders by requiring officers and directors to establish and maintain a permanent minimum ownership position in Company stock (based on the market value of our common stock), and by limiting the ability to sell Company stock until guideline ownership levels have been achieved. In addition, the Compensation Committee believes that the investment community values stock ownership by such officers and that share ownership demonstrates a commitment to and belief in the long-term strategic direction of Generac. Accordingly, stock ownership guidelines have been established for the Company's officers and directors, including all the named executive officers.

The current stock ownership guidelines are as follows:

COMMAND=ADD_TABLEWIDTH,"100%" User-specified TAGGED TABLE

Position/Level Multiple of Salary Requirement
CEO 4.0X annual base pay
CFO, EVP & SVP 2.0X annual base pay
Group Vice Presidents/GM 1.0X annual base pay

end of user-specified TAGGED TABLE

Executives are expected to build ownership value over time as a result of their performance and participation in the Company's equity compensation programs. Under the guidelines, no time period is specified for compliance for officers. The following retention ratios apply to each executive based on years of service and percentage of the guideline that has been achieved. Under the stock ownership guidelines, (i) an executive that has met 50% of the multiple of salary guideline and has less than 5 years of service has a 50% retention ratio, (ii) an executive that has met 50% of the multiple of salary guideline and has five or more years of service has a 25% retention ratio and (iii) an executive that has met less than 50% of the multiple of salary guideline has a 75% retention ratio. The Compensation Committee assesses progress towards meeting the guidelines on an annual basis. As of March 31, 2020, all five named executive officers, including the CEO and CFO, have met their ownership guidelines.

Outside directors have five years to meet their minimum ownership requirement. As of March 31, 2021, all Directors have met their ownership guidelines as follows:

(1) The amounts reported for 2020 represent the aggregate grant date fair value for awards of restricted stock, stock options, and performance shares and are computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Subtopic 718-10. See Note 17 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 for a discussion of the relevant assumptions used in calculating these amounts. All amounts represent potential future income calculated for financial reporting purposes; actual amounts recognized by the named executive officers may be materially different depending on, among other things, the Company's stock price performance and the period of service of the executive. The Stock Award amounts are composed in equal measure of restricted stock and performance shares, with the performance share portion assuming target performance by the Company during the relevant performance period. Assuming achievement of maximum performance during the relevant performance period for the performance shares, the Stock Award amounts provided would increase by a multiplier of 1.5. (2) The non-equity incentive plan compensation column reflects cash incentive awards earned pursuant to our Annual Performance Bonus Plan as previously described. These awards are earned during the year reflected and paid in the following year.

Simultaneously with the execution of Mr. Jagdfeld's employment agreement, we entered into a confidentiality, non-competition and intellectual property agreement ("Restrictive Covenant Agreement") with Mr. Jagdfeld. Pursuant to the Restrictive Covenant Agreement, Mr. Jagdfeld has agreed to maintain Confidential Information (as defined in the Restrictive Covenant Agreement) in confidence and secrecy and has agreed not to compete with us or solicit any of our employees during his employment and for a period of 24 months following his termination.

Although they have not entered into employment agreements, Messrs. Ragen, Minick, Forsythe, and Wilde have also signed employee nondisclosure and non-compete agreements. Our salary and bonus arrangements with Messrs. Ragen, Minick, Forsythe, and Wilde are described under "Compensation Discussion and Analysis—2020 Executive Compensation Program Decisions."

As previously disclosed, in November 2018, the Board approved and the Company adopted an Executive Change in Control Policy ("CIC Policy") applicable to all executive officers, excluding the CEO. Effective with this adoption, all previous Change in Control Severance Agreements between the Company and Messrs. Ragen, Minick, Forsythe, and Wilde were terminated. Additional detail regarding the CIC Policy is included below, and all capitalized terms used therein are as defined in the CIC Policy unless otherwise noted.

Under the CIC Policy, an eligible executive is entitled to severance benefits upon termination of employment by us without Cause or by the executive for Good Reason during the period commencing 120 days prior to the occurrence of a Change in Control and ending on the second anniversary of the date of the Change in Control.

Under the CIC Policy, a Change in Control is defined as any of the following: (a) acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person") of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of more than 50% of either (i) the then-outstanding shares of common stock of the Company (the "Outstanding Company Common Stock") or (ii) the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the "Outstanding Company Voting Securities"); provided, however, that for purposes of this subsection (a), the following acquisitions shall not constitute a Change in Control: (1) any acquisition directly from the Company, (2) any acquisition by the Company, (3) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company, or (4) any acquisition by any corporation pursuant to a transaction which complies with clauses (1) and (2) of subsection (c) of this definition; (b) the cessation for any reason of individuals who, as of November 5, 2018, constitute the Board (the "Incumbent Board") to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Company's stockholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board; (c) the consummation of

a reorganization, merger or consolidation or sale or other disposition of all or substantially all of the assets of the Company (a "Business Combination"), in each case, unless, following such Business Combination, (1) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of, respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Business Combination (including, without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company's assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be, and (2) at least a majority of the members of the board of directors of the corporation resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination; or (d) the approval by the stockholders of the Company of a complete liquidation or dissolution of the Company.

Cause is defined as: (a) An Executive's willful and continued failure to perform substantially his or her duties owed to the Employer (other than such failure resulting from a Disability) after a written demand for substantial performance is delivered to the Executive specifically identifying the nature of such unacceptable performance and is not cured by the Executive within a reasonable period, not to exceed 30 days; (b) An Executive is convicted of (or pleads guilty or no contest to) a felony or any crime involving moral turpitude; (c) An Executive has engaged in conduct that constitutes gross negligence or willful misconduct in the performance of his or her employment duties and/or deemed a material violation of a Company policy; (d) An Executive commits fraud, embezzlement, misappropriation of funds, breach of fiduciary duty, or a material act of dishonesty against the Company; (e) An Executive's drug addiction, habitual intoxication, or violation of the Company's Code of Ethics and Business Conduct and/or Supplemental Code of Ethics and Business Conduct adversely affects Executive's job performance and duties, or the reputation or best interests of the Company; or (f) An Executive's breach of any representation, warranty or covenant under this Policy, an award agreement, an employment agreement or other agreement or arrangement with an Employer. However, an act or omission by an Executive shall not be "willful" if conducted in good faith and with the Executive's reasonable belief that such conduct is in the best interests of the Employer.

Good Reason means, without the express written consent of an Executive, the occurrence of any of the following events during a Protection Period: (a) An Executive's Base Salary or target annual bonus opportunity under the Company's Annual Performance Bonus Plan or other similar annual bonus plan of the Company or any other Employer is reduced in excess of 5%, excluding across the board reductions affecting all executive officers of the Company; (b) An Executive's duties or responsibilities are negatively and materially changed in a manner inconsistent with the Executive's position (including status, offices, titles, and reporting responsibilities) or authority; or (c) The Company requires an Executive's principal office to be relocated more than 50 miles from its location as of the date immediate preceding a Change in Control. However, Good Reason shall not exist unless the Executive provides the Board not less than 30 nor more than 90 days' written notice, with specificity, of the grounds constituting Good Reason and an opportunity within such notice period for the Company to cure such grounds, and the Company fails to cure such grounds within the prescribed time period.

In the case of the outstanding restricted stock and performance share awards, the equity value represents the value of the shares (determined by multiplying the closing price of $227.41 per share on December 31, 2020 by the number of unvested shares of restricted stock and performance shares that would vest upon termination of employment, with the number of performance shares calculated at target achievement, and in accordance with the applicable award agreements). In the case of option awards, the equity value was determined by multiplying (i) the spread between the exercise price and the closing price of $227.41 per share on December 31, 2020 and (ii) the number of unvested option shares that would vest following termination

All severance benefits are subject to the Executive's execution and the effectiveness of a release of claims, as well as continued compliance with the nondisclosure and noncompete agreement between each Executive and the Company.

2020 DIRECTOR COMPENSATION

Pay Ratio Disclosure

In accordance with Item 402(u) of Regulation S-K, passed as part of the Dodd-Frank Wall Street Reform Act and Consumer Protection Act of 2010, we determined the ratio of the annual total compensation of Mr. Jagdfeld relative to the annual total compensation of our median employee.

Also in accordance with the rules, in 2020 we identified a new median employee using a multistep process that is permitted under the SEC rules. We first examined the annual cash compensation paid to each employee during 2020, which we gathered from payroll data. The total number of employees was 6,546, which included all full-time, part-time, and seasonal employees. We then examined the 2020 annualized base salaries for all individuals who were employed by us as of November 30, 2020. For purposes of reporting annual total compensation and the ratio of annual total compensation of the CEO to the median employee, both the CEO and median employee's annual total compensation were calculated consistent with the disclosure requirement of executive compensation under the Summary Compensation Table ("SCT"). Consistent with the prior two years and to present a holistic view of total compensation, we elected to include the value of health and welfare benefits in the annual total compensation of both our CEO and our median employee. The results are as follows:

Proposal 2 — Ratification of Selection of Independent Registered Public Accounting Firm

The Board of Directors recommends that the stockholders ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2021.

Although the Company is not required to seek stockholder approval of this appointment, the Board of Directors believes that doing so is consistent with good corporate governance practices. If the appointment is not ratified, the Audit Committee will explore the reasons for stockholder rejection and will reconsider the appointment.

Proposal 3 — Advisory Vote on Executive Compensation

As required by Regulation 14A of the Exchange Act, we are offering our stockholders an opportunity to cast an advisory vote on the compensation of our named executive officers, as disclosed in this proxy statement. Although the vote is non-binding, we value continuing and constructive feedback from our stockholders on compensation and other important matters. The Board and the Compensation Committee will consider the voting results when making future compensation decisions.

At the 2020 Annual Meeting of Stockholders, we provided our stockholders with the opportunity to cast an advisory vote on the compensation of our named executive officers as disclosed in the proxy statement for the 2020 Annual Meeting, and our stockholders overwhelmingly approved the proposal, with nearly 97% of the votes cast in favor. At the 2017 Annual Meeting, we asked our stockholders to indicate if we should hold an advisory vote on the compensation of our named executive officers every one, two or three years, with our Board recommending an annual advisory vote. Because our Board views it as a good corporate governance practice, and because at our 2017 Annual Meeting more than 90% of the votes cast were in favor of an annual advisory vote, we again are asking our stockholders to approve the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC's rules.

As described in the "Compensation Discussion and Analysis" section of this proxy statement, we believe that our executive compensation program enables us to attract, retain, and motivate a high-performance executive management team that improves our fundamental financial performance and provides value to the long-term interests of Generac and its stockholders.

We ask for your advisory vote on the following resolution:

The Audit Committee represents and assists the Board in fulfilling its oversight responsibility relating to (i) the integrity of the Company's financial statements and financial reporting process and the Company's systems of internal accounting and financial controls; (ii) the performance of the internal audit services function; (iii) the annual independent audits of the Company's financial statements and management's report regarding the effectiveness of the Company's system of internal control over financial reporting, the engagement of the independent auditors and the evaluation of the independent auditors' qualifications, independence and performance; (iv) the compliance by the Company with legal and regulatory requirements, including the Company's disclosure controls and procedures; (v) the evaluation of enterprise risk issues; and (vi) the fulfillment of the other responsibilities set out in the committee's charter. The Audit Committee has the responsibility for the engagement and retention of the Company's independent registered public accounting firm and the approval of all audit and other engagement fees.

In discharging its responsibilities, the Audit Committee is not itself responsible for the planning or conducting of audits or for any determination that the Company's financial statements are complete and accurate or in accordance with generally accepted accounting principles. The Company's management is primarily responsible for its financial statements and the quality and integrity of the reporting process. The independent registered public accounting firm Deloitte & Touche LLP ("Deloitte & Touche") is responsible for auditing those financial statements with accounting principles generally accepted in the United States of America.

In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed the audited consolidated financial statements for the year ended December 31, 2020, management's report of the effectiveness of the Company's system of internal control over financial reporting, and Deloitte & Touche's report of the effectiveness of the Company's system of internal control over financial reporting with the Company's management and representatives of the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC. In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence and has discussed with the independent registered public accounting firm its independence.

In reliance on its review of the audited consolidated financial statements, the review of the report of management on the effectiveness of the Company's internal control over financial reporting and Deloitte & Touche's report thereon, the discussions referred to above and the receipt of the written disclosures referred to above, the Audit Committee has recommended to the Board of Directors that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, for filing with the SEC.

Householding. The SEC's rules permit us to deliver a single Notice of Internet Availability or set of annual meeting materials to one address shared by two or more of our stockholders. This delivery method is referred to as "householding" and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one Notice of Internet Availability to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate Notice of Internet Availability to any stockholder at the shared address to which a single copy of the Notice of Internet Availability was delivered. If you are a record holder and if you prefer to receive separate copies of the proxy materials, or if you currently receive multiple copies and prefer to receive a single copy, please contact Raj Kanuru, Executive Vice President, General Counsel, and Secretary, Generac Holdings Inc., S45 W29290 Hwy. 59, Waukesha, Wisconsin 53189, or by telephone at (262) 544-4811.

INFORMATION CONCERNING SOLICITATION AND VOTING

Voting instructions (including instructions for both telephonic and internet proxies) are provided on the Notice of Internet Availability and on any proxy card you receive. The internet and telephone proxy procedures are designed to authenticate stockholder identities, to allow stockholders to give voting instructions and to confirm that stockholders' instructions have been recorded properly. A control number, located on the Notice of Internet Availability or proxy card, will identify stockholders and allow them to submit their proxies and confirm that their voting instructions have been properly recorded. Costs associated with electronic access, such as usage charges from internet access providers and telephone companies, must be borne by the stockholder. If you submit your proxy by internet or telephone, it will not be necessary to return a proxy card for your vote to be counted.

If a stockholder does not submit a proxy by the internet or by telephone or return a signed proxy card, and does not attend the meeting and vote in person, his or her shares will not be voted. Shares of our common stock represented by properly executed proxies received by us or proxies submitted by telephone or via the internet, which are not revoked, will be voted at the meeting in accordance with the instructions contained therein.

If instructions are not given and you do not indicate how your shares should be voted on a proposal, the shares represented by a properly completed proxy will be voted as the Board recommends. In addition, we reserve the right to exercise discretionary authority to vote proxies, in the manner determined by the Board in its sole discretion, on any matters brought before the 2021 annual meeting for which we did not receive adequate notice under the proxy rules promulgated by the SEC.

Any proxy signed and returned by a stockholder or submitted by telephone or via the internet may be revoked at any time before it is exercised by giving written notice of revocation to the Company's Secretary at our address set forth herein, by executing and delivering a later-dated proxy (either in writing, by telephone or via the internet) or by voting in person at the meeting. Attendance at the meeting will not, in and of itself, constitute revocation of a proxy.

If your shares are held in the name of a bank, broker, fiduciary or custodian, follow the voting instructions on the form you receive from your record holder. The availability of internet and telephone proxies for these stockholders will depend on their voting procedures.

COMMAND=STYLE_ADDED,"margin-left:18.0pt;text-indent:-18.0pt;" Quorum

The presence at the annual meeting, in person or by proxy, of the holders of at least a majority of the number of shares of common stock issued and outstanding and entitled to vote as of the record date, is required to constitute a quorum to transact business at the annual meeting. Abstentions and broker non-votes will be counted toward the establishment of a quorum.

INFORMATION CONCERNING SOLICITATION AND VOTING

COMMAND=STYLE_ADDED,"margin-left:18.0pt;text-indent:-18.0pt;" Required Votes

Election of Nominees named herein as Class III Directors. Under our Amended and Restated Bylaws (the " Bylaws "), the affirmative vote of a plurality of shares of common stock voting on this matter at the annual meeting is required to elect each nominee named herein as a director. Consequently, only shares that are voted in favor of a particular nominee will be counted toward such nominee's achievement of a plurality. Notwithstanding the foregoing, if a nominee for Director receives more "withheld" or "against" votes for his or her election than votes "for" his or her election in an uncontested election at a meeting of stockholders, the Director shall, in accordance with and subject to our Corporate Governance Guidelines and Principles, promptly tender his or her resignation to the Board.

Ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm. Proposal 2, relating to the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2021, will be approved if it receives the affirmative vote of a majority of the shares of common stock represented at the annual meeting and entitled to vote.

Approval of Non-Binding "Say-on-Pay" Resolution Regarding Executive Compensation. Proposal 3, relating to the non-binding resolution to approve our executive compensation, will be approved if it receives the affirmative vote of a majority of the shares of common stock represented at the annual meeting and entitled to vote.

Other Matters. If any other matters are properly presented at the annual meeting for action, including a question of adjourning or postponing the meeting from time to time, the persons named in the proxies and acting thereunder will have discretion to vote on such matters in accordance with their best judgment.

Impact of Abstentions. A shareholder who abstains on Proposal 2 or 3 will have the effect of voting against such proposal.

COMMAND=STYLE_ADDED,"margin-left:18.0pt;text-indent:-18.0pt;" Shares Held by Brokers

If you are the beneficial owner of shares held for you by a broker, your broker must vote those shares in accordance with your instructions. If you do not give voting instructions to your broker, your broker may vote your shares for you on any discretionary items of business to be voted upon at the annual meeting. If you do not provide voting instructions on a nondiscretionary item, including the election of the nominees named herein as directors, the shares will be treated as "broker nonvotes." We believe that the ratification of the appointment of Deloitte & Touche LLP (Proposal 2) is a routine matter on which brokers will generally be permitted to vote any unvoted shares in their discretion. We believe that election of the four nominees named herein as Class III directors (Proposal 1) and the advisory, nonbinding "say-on-pay" resolution (Proposal 3) are nonroutine matters on which brokers will not be permitted to vote any unvoted shares. "Broker nonvotes" will be included in determining the presence of a quorum at the annual meeting, but will have no effect on the outcome of any proposal.
