INFORMATION ABOUT THIS PROXY STATEMENT

Why you received this proxy statement.    You are viewing or have received these proxy materials because Neff Corporation's Board of Directors is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you pursuant to the rules of the Securities and Exchange Commission ("SEC") and that is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials.    As permitted by SEC rules, Neff Corporation is making this proxy statement and its 2016 Annual Report available to its stockholders electronically via the Internet. On or about April 3, 2017, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the "Internet Notice") containing instructions on how to access this proxy statement and our 2016 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2016 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Internet Notice.

Printed Copies of Our Proxy Materials.    If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card included in the materials.

Householding.    The SEC's rules permit us to deliver a single Internet Notice or set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as "householding" and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one Internet Notice or one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the Internet Notice or proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered. If you prefer to receive separate copies of the Internet Notice or proxy materials, contact Broadridge Financial Solutions, Inc. at (800) 542-1061 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

Questions and Answers about the 2017 Annual Meeting of Stockholders

WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?

The Record Date for the Annual Meeting is March 20, 2017. You are entitled to vote at the Annual Meeting only if you were a holder of record of Class A Common Stock or Class B Common Stock at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. Each outstanding share of Class A Common Stock and Class B Common Stock is entitled to one vote for all matters to come before the Annual Meeting. At the close of business on the Record Date, there were 8,859,662 shares of Class A Common Stock and 14,951,625 shares of Class B Common Stock issued and outstanding and entitled to vote at the Annual Meeting. The holders of Class A Common Stock and Class B Common Stock will vote together as a single class on each matter to come before the Annual Meeting.

WHAT IS THE DIFFERENCE BETWEEN BEING A "RECORD HOLDER" AND HOLDING SHARES IN "STREET NAME"?

A record holder holds shares in his or her name. Shares held in "street name" means shares that are held in the name of a bank or broker on a person's behalf.

AM I ENTITLED TO VOTE IF MY SHARES ARE HELD IN "STREET NAME"?

Yes. If your shares are held by a bank or a brokerage firm, you are considered the "beneficial owner" of those shares held in "street name." If your shares are held in street name, these proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm on how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. If your shares are held in street name, you may not vote your shares in person at the Annual Meeting unless you obtain a legal proxy from your bank or brokerage firm.

HOW MANY SHARES MUST BE PRESENT TO HOLD THE ANNUAL MEETING?

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, in person or by proxy, of the holders of a majority in voting power of the Common Stock outstanding and entitled to vote on the Record Date will constitute a quorum.

WHO CAN ATTEND THE 2017 ANNUAL MEETING OF STOCKHOLDERS?

You may attend the Annual Meeting only if you are a Neff Corporation stockholder who is entitled to vote at the Annual Meeting, or if you hold a valid proxy for the Annual Meeting. If you would like to attend the Annual Meeting, you must call Brian Coolidge at 305-513-3350 extension 2243 no later than 5:00 p.m. Eastern time on May 9, 2017 to have your name placed on the attendance list. In order to be admitted into the Annual Meeting, your name must appear on the attendance list and you must present government-issued photo identification (such as a valid driver's license). If your bank or broker holds your shares in street name, you will also be required to present proof of beneficial ownership of our Common Stock on the Record Date, such as the Internet Notice you received from your bank or broker, or a bank or brokerage statement or a letter from your bank or broker showing that you owned shares of our Common Stock at the close of business on the Record Date.

WHAT IF A QUORUM IS NOT PRESENT AT THE ANNUAL MEETING?

If a quorum is not present at the scheduled time of the Annual Meeting, a majority in voting power of the stockholders entitled to vote at the Annual Meeting, present in person or represented by proxy, may adjourn the Annual Meeting.

QUESTIONS AND ANSWERS ABOUT THE 2017 ANNUAL MEETING OF STOCKHOLDERS

WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE INTERNET NOTICE OR MORE THAN ONE SET OF PROXY MATERIALS?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

HOW DO I VOTE?

We recommend that stockholders vote by proxy even if they plan to attend the Annual Meeting and vote in person. If you are a stockholder of record, there are three ways to vote by proxy:

•

by Internet—You can vote over the Internet at www.proxyvote.com by following the instructions on the Internet Notice or proxy card;

•

by Telephone—You can vote by telephone by calling 1-800-690-6903 and following the instructions on the proxy card; or

•

by Mail—You can vote by mail by signing, dating and mailing the proxy card, which you may have received by mail.

Telephone and Internet voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m., Eastern time, on May 15, 2017.

If your shares are held in street name through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Telephone and Internet voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares in person at the Annual Meeting, you should contact your bank or broker to obtain a legal proxy and bring it to the Annual Meeting in order to vote.

CAN I CHANGE MY VOTE AFTER I SUBMIT MY PROXY?

Yes.

If you are a registered stockholder, you may revoke your proxy and change your vote:

•

by submitting a duly executed proxy bearing a later date;

•

by granting a subsequent proxy through the Internet or telephone;

•

by giving written notice of revocation to the Secretary of Neff Corporation prior to or at the Annual Meeting; or

•

by voting in person at the Annual Meeting.

Your most recent proxy card or internet or telephone proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Secretary before your proxy is voted or you vote in person at the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote in person at the Annual Meeting by obtaining a legal proxy from your bank or broker and submitting the legal proxy along with your ballot.

WHO WILL COUNT THE VOTES?

A representative of Broadridge Financial Solutions, Inc., our inspector of election, will tabulate and certify the votes.

WHAT IF I DO NOT SPECIFY HOW MY SHARES ARE TO BE VOTED?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board of Directors. The Board of Directors' recommendations are indicated on page 3 of this proxy statement, as well as with the description of each proposal in this proxy statement.

QUESTIONS AND ANSWERS ABOUT THE 2017 ANNUAL MEETING OF STOCKHOLDERS

WILL ANY OTHER BUSINESS BE CONDUCTED AT THE ANNUAL MEETING?

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, the proxy holders named on the Company's proxy card will vote your shares in accordance with their best judgment.

HOW MANY VOTES ARE REQUIRED FOR THE APPROVAL OF THE PROPOSALS TO BE VOTED UPON AND HOW WILL ABSTENTIONS AND BROKER NON-VOTES BE TREATED?

Proposal	Votes required	Effect of Votes Withheld / Abstentions and Broker Non-Votes
Proposal 1: Election of Directors	The plurality of the votes cast. This means that the nominees receiving the highest number of affirmative "FOR" votes by holders of Common Stock will be elected as Class III Directors.	Votes withheld and broker non-votes will have no effect.
Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm	The affirmative vote of the holders of a majority in voting power of the shares of Common Stock which are present in person or by proxy and entitled to vote on the proposal.	Abstentions will have the same effect as votes against the proposal. We do not expect any broker non-votes on this proposal.

WHAT IS AN ABSTENTION AND HOW WILL VOTES WITHHELD AND ABSTENTIONS BE TREATED?

A "vote withheld," in the case of the proposal regarding the election of directors, or an "abstention," in the case of the proposal regarding the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm, represents a stockholder's affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors. Abstentions have the same effect as votes against on the ratification of the appointment of Deloitte & Touche LLP.

WHAT ARE BROKER NON-VOTES AND DO THEY COUNT FOR DETERMINING A QUORUM?

Generally, broker non-votes occur when shares held by a broker in "street name" for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors. Broker non-votes count for purposes of determining whether a quorum is present.

WHERE CAN I FIND THE VOTING RESULTS OF THE 2017 ANNUAL MEETING OF STOCKHOLDERS?

We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC after the Annual Meeting.

PROPOSALS TO BE VOTED ON
PROPOSAL 1—Election of Directors

At the Annual Meeting, two (2) Class III Directors are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2020 and until such directors' successors are elected and qualified or until such directors' earlier death, resignation or removal.

We currently have six (6) directors on our Board. The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the nominees receiving the highest number of affirmative "FOR" votes will be elected as Class III Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

Our Board of Directors is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting of stockholders following election or such director's death, resignation or removal, whichever is earliest to occur. The current class structure is as follows: Class I, whose term will expire at the 2018 Annual Meeting of Stockholders; Class II, whose term will expire at the 2019 Annual Meeting of Stockholders, and Class III, whose term currently expires at the 2017 Annual Meeting of Stockholders and whose subsequent term will expire at the 2020 Annual Meeting of Stockholders. The current Class I Directors are Graham Hood and Michael Sileck; the current Class II Directors are Joseph Deignan and Robert Singer; and the current Class III Directors are James Continenza and Gerard E. Holthaus.

As indicated in our Amended and Restated Certificate of Incorporation, our Board of Directors consists of such number of directors as determined from time to time by resolution adopted by a majority of the total number of authorized directors. Any additional directorships resulting from an increase in the number of directors may be filled only by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of Common Stock represented by the proxy for the election of James Continenza and Gerard E. Holthaus as Class III Directors. Messrs. Continenza and Holthaus are currently serving as our Class III Directors. In the event that either of Messrs. Continenza and Holthaus should become unable to serve or for good cause will not serve as a director, it is intended that votes will be cast for a substitute nominee designated by the Board of Directors or the Board may elect to reduce its size. The Board of Directors has no reason to believe that Messrs. Continenza and Holthaus will be unable to serve if elected. Messrs. Continenza and Holthaus have consented to being named in this proxy statement and to serve if elected.

VOTE REQUIRED

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the nominees receiving the highest number of affirmative "FOR" votes will be elected as Class III Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors unanimously recommends a vote FOR the election of the Class III Director nominees below.

The principal occupations and business experience, for at least the past five years, of each Class III Nominee for election at the 2017 Annual Meeting are as follows:

James Continenza has served as the Chairman of the board of managers of Neff Holdings since October 2010 and has served as our Chairman of the Board since being appointed to our Board of Directors in November 2014. Mr. Continenza has been the Chief Executive Officer of Vivial Holdings I, Inc. (f/k/a TBC Holdings I, Inc.), the parent company of Vivial, LLC (f/k/a The Berry Company, LLC), a holding company created to acquire and manage various advertising, marketing and technology companies focused primarily on providing a wide range of digital and legacy leads-generating products to local and national advertisers, from September 2012 to the present. Prior to joining Vivial Holdings I, Inc., Mr. Continenza was President of STi Prepaid, LLC, a provider of various domestic and international long distances services in the United States, from June 2010 to February 2011.

We believe that Mr. Continenza's industry expertise, leadership and board expertise makes him well-qualified to serve as a member of our Board of Directors.

GERARD E. HOLTHAUS Age 67

Gerard E. Holthaus was appointed to our Board of Directors in November 2014. Mr. Holthaus has been the non-executive Chairman of the Board of Algeco Scotsman, a provider of modular space solutions and rental services company, since April 2010, prior to which Mr. Holthaus was the executive Chairman of the Board and Chief Executive Officer of Algeco Scotsman from November 2007 to April 2010.

Mr. Holthaus currently serves as either chair or director on the boards of FTI Consulting, Inc., the Baltimore Life Companies and Baker Tanks. Mr. Holthaus also currently serves as a trustee of Loyola University Maryland. We believe Mr. Holthaus' financial, executive and board experience makes him well-qualified to serve as a member of our Board of Directors.

CONTINUING MEMBERS OF THE BOARD OF DIRECTORS:
CLASS I DIRECTORS (TERMS TO EXPIRE AT THE 2018 ANNUAL MEETING)

The current members of the Board of Directors who are Class I Directors are as follows:

The principal occupation and business experience, for at least the past five years, of each Class I Director are as follows:

GRAHAM HOOD Age 61

Graham Hood was appointed to our Board of Directors in August 2014. Mr. Hood has served as our and Neff Holdings Corp.'s, a predecessor entity, Chief Executive Officer since June 2007.

In May 2010, Neff Holdings Corp. filed for protection under Chapter 11 of the United States Bankruptcy Code. At the time of such filing, Mr. Hood was an executive officer of Neff Holdings Corp.

PROPOSAL 2—Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee has appointed Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2017. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of Deloitte & Touche LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

Deloitte & Touche LLP also served as our independent registered public accounting firm for the fiscal year ended December 31, 2016. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of Deloitte & Touche LLP is expected to attend the Annual Meeting, make a statement if so desired and be available to respond to appropriate questions from stockholders.

In the event that the appointment of Deloitte & Touche LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent auditors for the fiscal year ending December 31, 2018. Even if the appointment of Deloitte & Touche LLP is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the best interests of Neff Corporation.

VOTE REQUIRED

This proposal requires the approval of the affirmative vote of the holders of a majority in voting power of the shares of Common Stock of the Company which are present in person or by proxy and entitled to vote thereon. Abstentions will have the same effect as a vote against this proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of Deloitte & Touche LLP, we do not expect any broker non-votes in connection with this proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors unanimously recommends a vote FOR the Ratification of the Appointment of Deloitte & Touche LLP as our Independent Registered Public Accounting Firm.

Report of the Audit Committee of the Board of Directors

The Audit Committee has reviewed Neff Corporation's audited financial statements for the fiscal year ended December 31, 2016 and has discussed these financial statements with management and Neff Corporation's independent registered public accounting firm. The Audit Committee has also received from, and discussed with, Neff Corporation's independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by statement on Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board ("PCAOB").

Neff Corporation's independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and Neff Corporation, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from Neff Corporation.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in Neff Corporation's Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Corporate Governance

GENERAL

Our Board of Directors has adopted Corporate Governance Guidelines, a Code of Ethics for Chief Executive and Senior Financial Officers, a Code of Ethics and Conduct for all officers, directors and employees and charters for our Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of Neff Corporation. You can access our current committee charters, our Corporate Governance Guidelines, our Code of Ethics for Chief Executive and Senior Financial Officers and our Code of Ethics and Conduct in the "Corporate Governance" section of the "Investors" page of our website located at www.neffrental.com, or request a copy by writing to our Secretary at our offices at 3750 N.W. 87^th Avenue, Suite 400, Miami, Florida 33178.

BOARD COMPOSITION

Our Board of Directors currently consists of six (6) directors: James Continenza, Joseph Deignan, Gerard E. Holthaus, Graham Hood, Michael Sileck and Robert Singer. As indicated in our Amended and Restated Certificate of Incorporation, our Board of Directors consists of such number of directors as determined from time to time by resolution adopted by a majority of the total number of authorized directors. Any additional directorships resulting from an increase in the number of directors may be filled only by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors.

Our Board of Directors is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting following election or such director's death, resignation or removal, whichever is earliest to occur. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors.

CONTROLLED COMPANY EXEMPTIONS

As a result of the significant ownership of our Class B Common Stock by Wayzata, more than 50% of the combined voting power of our Common Stock is held by Wayzata. As a result, we are a "controlled company" under the rules of the New York Stock Exchange ("NYSE"). As a controlled company, we are not required to comply with certain corporate governance requirements, including the following requirements: that a majority of our Board of Directors consists of "independent directors," as defined under the NYSE rules; that we have a nominating and corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities; that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities; and that we conduct an annual performance evaluation of our Nominating and Corporate Governance Committee and Compensation Committee.

DIRECTOR INDEPENDENCE

Our Board of Directors has affirmatively determined that each of James Continenza, Joseph Deignan, Gerard E. Holthaus, Michael Sileck and Robert Singer is an "independent director," as defined under NYSE rules. In evaluating and determining the independence of the directors, the Board considered that Neff Corporation may have certain relationships with its directors. Specifically, the Board considered that Mr. Deignan is affiliated with Wayzata, which owns all of our outstanding Class B Common Stock as of March 20, 2017, which consists of

15

CORPORATE GOVERNANCE

approximately 63% of the voting power of our Common Stock. The Board of Directors determined that Mr. Deignan is not independent for purposes of Rule 10A-3 under the Securities Exchange Act of 1934 (the "Exchange Act") and as a result is not independent for our audit committee because of his affiliation with Wayzata. As of October 16, 2015, Mr. Deignan no longer serves as a member of our audit committee. The Board determined that Mr. Deignan's affiliation with Wayzata does not, however, impair his independence from us and our management under the rules of the NYSE. The Board also considered that Wayzata, Mr. Singer and Mr. Continenza are parties to the Tax Receivable Agreement, and noted that no payments to Mr. Singer, Mr. Continenza or Wayzata were made under the agreement in 2016.

DIRECTOR CANDIDATES

The Nominating and Corporate Governance Committee is responsible for identifying and reviewing the qualifications of potential director candidates and recommending to the Board those candidates to be nominated for election to the Board.

To facilitate the search process for director candidates, the Nominating and Corporate Governance Committee may solicit our current directors and executives for the names of potentially qualified candidates or may ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders.

Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates' independence from us and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee of candidates for election as director.

In accordance with our Corporate Governance Guidelines, in evaluating the suitability of individual candidates, the Nominating and Corporate Governance Committee will consider (i) individual qualifications, including the ability to make independent judgments, general understanding of the Company's business, other board service, professional background, education and diversity and (ii) whether the candidate possesses the highest personal and professional ethics, integrity and values.

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, Neff Corporation, 3750 N.W. 87^th Avenue, Suite 400, Miami, Florida 33178. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

COMMUNICATIONS FROM INTERESTED PARTIES

The Board of Directors provides a process for interested parties, including stockholders, to send communications to the Board. Anyone who would like to communicate with, or otherwise make his or her concerns known directly to the Chairman of the Board, chairperson of any of the Audit, Nominating and Corporate Governance, and Compensation Committees, or to the non-management or independent directors as a group, may do so by addressing such communications or concerns to the Secretary of the Company, 3750 N.W. 87^th Avenue, Suite 400, Miami, Florida 33178, who will forward all communications that, in his or her judgment, are appropriate for consideration to the appropriate party. Examples of communications that would not be appropriate for consideration by the directors include commercial solicitations and matters not relevant to the shareholders, to the

16

CORPORATE GOVERNANCE

functioning of the board, or to the affairs of the Company. Such communications may be done confidentially or anonymously.

BOARD LEADERSHIP STRUCTURE AND ROLE IN RISK OVERSIGHT

Our Board of Directors is currently chaired by Mr. Continenza, while Mr. Hood serves as our Chief Executive Officer. Based on the Company's present circumstances, our Board of Directors believes that the Company and its stockholders are best served by having Mr. Continenza serve as its Chairman of the Board and Mr. Hood serve as its Chief Executive Officer. Our current leadership structure permits Mr. Hood to focus his attention on managing our Company and permits Mr. Continenza to manage the Board. Accordingly, we believe our current leadership structure is the optimal structure for us at this time.

Our Board of Directors is responsible for overseeing our risk management process. Our Board of Directors focuses on our general risk management strategy, the most significant risks facing us, and oversees the implementation of risk mitigation strategies by management. Our Board of Directors is also apprised of particular risk management matters in connection with its general oversight and approval of corporate matters and significant transactions. Our Board of Directors does not believe that its role in the oversight of our risks affects the Board's leadership structure.

RISK CONSIDERATIONS IN OUR COMPENSATION PROGRAM

We believe our compensation policies present no risks that are reasonably likely to have a material adverse effect on our Company.

CODE OF ETHICS

We have adopted a Code of Ethics and Conduct that applies to all of our directors, officers and employees and a Code of Ethics for Chief Executive and Senior Financial Officers. Copies of each of the codes are available on our website at www.neffrental.com in the "Corporate Governance" section of the "Investors" page. We expect that any amendments to either of the codes, or any waivers of either of their requirements, that are required to be disclosed by SEC or NYSE rules will be disclosed on our website.

ATTENDANCE BY MEMBERS OF THE BOARD OF DIRECTORS AT MEETINGS

There were five meetings of the Board of Directors during the fiscal year ended December 31, 2016. During the fiscal year ended December 31, 2016, each director attended at least 75% of the aggregate of (i) all meetings of the Board of Directors and (ii) all meetings of the committees on which the director served during the period in which he served as a director.

Currently, we do not maintain a formal policy regarding director attendance at the Annual Meeting; however, it is expected that absent compelling circumstances, directors will attend. All of our directors attended the 2016 annual meeting of stockholders.

EXECUTIVE SESSIONS

The non-management members of the Board meet in regularly scheduled executive sessions. James Continenza presides over the regularly scheduled executive sessions.

17

Our Board has established three standing committees—Audit, Compensation and Nominating and Corporate Governance—each of which operates under a written charter that has been approved by our Board.

Other than as described above, Lyons was not asked to perform any other services for the Compensation Committee or the Company during 2016. The Compensation Committee assessed the independence of Lyons taking into account the factors outlined in the New York Stock Exchange's listing rules. Based on its assessment, the Compensation Committee agreed that Lyons is independent and that Lyons' work has not raised any conflict of interest.

As an emerging growth company, we provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012, including the executive compensation disclosures required of a "smaller reporting company." In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which votes must be conducted.

Employment Letter with Westley Parks

Employment Term and Position

            Mr. Parks is party to an employment letter pursuant to which he previously served as the Vice President—Atlantic Region. In 2015, Mr. Parks was promoted to Chief Operating Officer.

Base Salary, Annual Bonus, Benefits

            Pursuant to the terms of his employment letter, Mr. Parks is entitled to an annual base salary of $242,000. Mr. Parks' base salary was subsequently increased to $314,000 per year and to $329,000 effective as of August 29, 2016. In 2014, Mr. Parks was also eligible to receive an annual bonus in accordance with the Regional Vice

23

EXECUTIVE AND DIRECTOR COMPENSATION

President Bonus Plan. In 2016, Mr. Parks was eligible for an annual cash incentive performance-based bonus, as determined in accordance with certain performance measures. The target annual bonus for which Mr. Parks was eligible for 2016 was 85% of annual base salary. For a further description of the cash incentive bonuses that have been awarded Mr. Parks, please see below under "—Annual Cash Incentive Compensation. Further, Mr. Parks is eligible for health benefits and a car allowance.

Severance

            Mr. Parks' employment letter provides for severance upon a termination by us without cause or by Mr. Parks for good reason pursuant to our Severance Policy (as described below). In accordance with our Severance Policy, upon a termination of Mr. Parks' employment by us without cause or by reason of his resignation for "good reason" (as defined in the Severance Policy), Mr. Parks is entitled to severance consisting of (a) continued base salary for 24 months, payable in 24 monthly installments, and (b) continued health benefits for the same 24-month period. We have the option to reduce Mr. Parks' severance package by the same amount by which we reduce the duration of Mr. Parks' non-compete period (as described below), should we choose to do so, but by no more than 50% in either case. The Neff Holdings Executive Severance Policy (the "Severance Policy") defines "good reason" generally as (i) a material reduction in the executive's annual base salary, (ii) a material modification of the executive's duties where such modification constitutes a demotion, or (iii) the required relocation (on a permanent basis) of the executive's office location by more than 50 miles from his or her current office location.

Restrictive Covenants

            Pursuant to his employment letter, Mr. Parks is subject to non-competition and non-solicitation restrictions for a 24 month period after termination of employment, subject to reduction or clawback in accordance with the terms of the Severance Policy. As described above, in accordance with our Severance Policy, we are permitted to reduce the duration of Mr. Parks' non-compete period by up to 50%, which will result in a corresponding reduction in Mr. Parks' severance payment by the same percentage.

Annual Cash Incentive Compensation

            For 2016, we sponsored the Neff Corporation Senior Executive Incentive Bonus Plan whereby Messrs. Hood, Irion and Parks were eligible pursuant to the performance goals set by the Compensation Committee (the "CEO, CFO and COO Bonus Plan") for a target bonus equal to 100%, 92% and 85% of base salary, respectively, based on the achievement of a target amount of corporate rental EBITDA, which we calculate as Adjusted EBITDA excluding any gain from sales of rental equipment, and based on the achievement of a target amount of corporate rental EBITDA minus net capital expenditure targets, with a maximum bonus payout equal to 150%, 135% and 125% of base salary, respectively for each of Messrs. Hood, Irion and Parks. Pursuant to the CEO, CFO and COO Bonus Plan, Mr. Irion's bonus was also subject to certain key performance objectives, or "KPOs," related to timeliness and accuracy of financial reporting, assisting rental rate improvement and achieving year over year drop down goal of 60%. For each KPO not achieved, Mr. Irion's bonus could have been reduced by 10%; however, all of the KPOs for 2016 were achieved. Pursuant to the CEO, CFO and COO Bonus Plan, Mr. Parks bonus was also subject to certain KPOs related to the successful rollout of revenue optimization strategy, the improvement of time utilization and gaining efficiencies with the Company's fleet management and increased operational efficiencies through the standardizing of regional best practices. For each KPO not achieved, Mr. Parks bonus could have been reduced by 10%; however, all of the KPOs for 2016 were achieved. Mr. Hood's bonus was not subject to any KPOs for 2016.

            The actual dollar amounts of performance-based bonuses awarded to each named executive officer for 2016 performance are set forth above in the "2016 Summary Compensation Table" in the column titled "Non-Equity Incentive Plan Compensation." Such actual performance-based bonuses represent 91.3% achievement of the corporate rental EBITDA targets for 2016.

EXECUTIVE AND DIRECTOR COMPENSATION

Equity-Based Compensation Awards

            Prior to our IPO, we adopted the 2014 Incentive Award Plan in order to facilitate the grant of cash and equity incentives to directors, employees (including our named executive officers) and consultants of our company and certain of its affiliates and to enable our company and certain of its affiliates to obtain and retain the services of these individuals, which is essential to our long-term success. The 2014 Incentive Award Plan provides for the grant of stock options, including incentive stock options, nonqualified stock options, restricted stock, dividend equivalents, stock payments, restricted stock units, or "RSUs," deferred stock, deferred stock units, performance awards, and stock appreciation rights. In connection with the adoption of the 2014 Incentive Award Plan, we determined to make no further grants under the Neff Holdings Management Equity Plan, as adopted October 1, 2010 (the "2010 Option Plan").

            In 2016, we granted equity awards with respect to 221,015 shares of our Class A common stock under the 2014 Incentive Award Plan, consisting of 131,432 options and 89,583 RSUs, to certain of our directors and employees, including the named executive officers (the "2016 grants"). The 2016 grants for Messrs. Hood, Irion and Parks had a grant date fair value equal to 100%, 70% and 60% of their base salaries, respectively. Each named executive officer's 2016 grant was composed of 50% of stock options and 50% of RSUs. The stock options will vest, subject to continued employment, in equal annual installments on the first four anniversaries of the date of grant, which was December 9, 2016. The RSUs will cliff-vest on December 9, 2019, subject to continued employment (except as otherwise described above with respect to Messrs. Hood and Irion), and (a) in the case of 50% of each such executive's RSUs, only if the Company's return on invested capital for the three-year period from the date of grant exceeds its weighted average cost of capital for such period and (b) in the case of the other 50% of each such executive's RSUs, only if our total stockholder return, as measured for such period, is equal to or greater than the median total stockholder return of companies in the S&P Trading Companies and Distributors GICS Sub-Industry for such period.

            For additional information about all outstanding options and restricted stock units held by our named executive officers, please see the "Outstanding Equity Awards at Fiscal Year End" table below.

Other Elements of Compensation

Retirement Plans

            We currently maintain the Neff Rental 401(k) Plan (the "401(k) Plan"), a 401(k) retirement savings and profit-sharing plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our named executive officers are eligible to participate in the 401(k) Plan on the same terms as other full-time employees. The Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) Plan. Currently, we provide a discretionary match of contributions made by participants in the 401(k) Plan, whereby our matching contributions begin to vest upon the participant's completion of his or her second year of service and continue vesting ratably on each of the next four anniversaries thereafter through the participant's sixth year of service. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) Plan, and making matching contributions, adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

            We do not maintain any qualified pension plans or non-qualified deferred compensation plans.

Employee Benefits and Perquisites

            All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including:

•

medical, dental and vision benefits;

25

EXECUTIVE AND DIRECTOR COMPENSATION

•

medical and dependent care flexible spending accounts;

•

short-term and long-term disability insurance; and

•

life insurance.

            We also provide members of our management team, including our named executive officers, with a car allowance.

            We believe the benefits and perquisites described above are necessary and appropriate to provide a competitive compensation package to our named executive officers.

Other Compensation Programs

Neff Holdings Amended and Restated Sale Transaction Bonus Plan

            We entered into a transaction bonus plan whereby certain service providers (including our named executive officers and certain of our non-employee directors) are eligible to receive cash payments upon a sale transaction (defined as (i) a change in control of Neff Holdings, or (ii) (a) an underwritten public offering by Neff Holdings or Neff Corporation pursuant to an effective registration statement covering securities of either such entity or any of their respective equityholders to the public (a "Public Offering") or (b) a sale or transfer by Wayzata of equity securities of Neff Holdings or Neff Corporation (a "Wayzata Sale") that, in the case of (a) or (b), together with all previous Public Offerings (including the IPO) or Wayzata Sales, involves aggregate cash proceeds from the sale of such equity securities of at least $175,000,000. Payments under the sale transaction bonus plan are subject to the continued employment or services of the employee or director at the time of consummation of the applicable event and execution of a release of claims against the company. With respect to our option holders, including the named executive officers and non-employee directors, the cash payments are intended to compensate them for loss in value of their stock options resulting from a distribution of cash we previously made to our sponsor in 2013. All option holders will receive such payments on a pro rata basis based on the number of stock options they hold. If a sale transaction or qualified public offering occurs as stated above, the plan will pay out to participants a total of approximately $9.9 million, subject to a minimum enterprise value goal of $900.0 million for certain employees other than the named executive officers. Our named executive officers, Messrs. Hood, Irion and Parks, are eligible to receive payments pursuant this plan equal to $2,606,522, $1,554,349 and $717,391, respectively. Certain of our non-employee directors, Messrs. Continenza and Singer, are eligible to receive payments pursuant to this plan equal to $150,333 and $105,233, respectively. The sale transaction bonuses will be payable in a lump sum within 30 days following the closing date of a qualifying sale transaction. Because our IPO did not raise at least $175,000,000, no payments under this plan were triggered in connection with our IPO.

Neff Holdings 2014 Incentive Bonus Plan

            Pursuant to the 2014 Incentive Bonus Plan, certain service providers (including our named executive officers and certain of our non-employee directors) were granted a contingent right to receive cash distribution awards in connection with our sponsor's receipt of a specified level of proceeds in connection with the sale, disposition or transfer of its common units in Neff Holdings. These cash payments were intended to compensate the participants for the loss in value of their stock options resulting from the distribution of cash we made to our sponsor in 2013. All option holders were eligible to receive such payments on a pro rata basis based on the number of stock options they held. Under this plan, once our sponsor receives cash proceeds of at least $81,000,000, we will fund an incentive pool of $2,100,000 and at such time as our sponsor receives cash proceeds of at least $108,000,000, we will fund an additional incentive pool of $2,100,000. Our named executive officers, Messrs. Hood, Irion and Parks, were eligible to receive 28.01%, 16.70% and 7.71% of the incentive pool, respectively, in a single, lump sum payment pursuant to the terms of their individual written award agreements, subject to continued employment

26

EXECUTIVE AND DIRECTOR COMPENSATION

through the relevant date at which the incentive pool is established and subject to the execution of a non-revocable release of claims. Our non-employee directors, Messrs. Continenza and Singer, were eligible to receive 1.62% and 1.13% of the incentive pool, respectively, in a single, lump sum payment pursuant to the terms of their individual written award agreements, subject to continued services through the relevant date at which the incentive pool is established and subject to the execution of a non-revocable release of claims. Proceeds from our IPO counted toward the threshold under this cash incentive plan, but only to the extent that Wayzata received proceeds in connection with its sale, disposition or transfer of its common units in Neff Holdings. However, although IPO proceeds counted towards the necessary thresholds under this plan, the initial threshold was not reached in connection with our IPO and thus no payments were made to our named executive officers under the 2014 Incentive Bonus Plan in connection with our IPO.

No Tax Gross-Ups

            We do not make gross-up payments to cover our named executive officers' personal income taxes that may pertain to any of the compensation or perquisites paid or provided by our company.

Executive Stock Ownership Policy

            We adopted an executive stock ownership policy in connection with our IPO which will encourage our executives, within five years of our IPO, to hold shares of our common stock with a value equal to a specified multiple of base salary (five times annual base salary, in the case of the Chief Executive Officer, three times annual base salary, in the case of the Chief Financial Officer and our executive and senior vice presidents, and one times annual base salary, in the case of our other vice presidents).

Represents the aggregate fair market value on the date of grant for restricted stock units granted in the 2016 fiscal year. See Note 12-Equity-Based Compensation of the Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 for the assumptions used in valuing such restricted stock units.

              The following table sets forth the aggregate numbers of options and restricted stock units held by each of our non-employee directors as of December 31, 2016.

Name	Grant Date	Aggregate Number of Options Outstanding at Fiscal Year End (#) (a)	Aggregate Number of RSU Awards Outstanding at Fiscal Year End (#) (b)
James Continenza	11/11/2010	20,433

(a)

Reflects options to purchase common units of Neff Holdings held by our non-employee directors pursuant to the Neff Holdings 2010 Option Plan, subject to service-based vesting restrictions, which were converted from options to purchase Class B units of Neff Holdings in connection with our IPO. All such options have an exercise price of $6.66 per unit. The options vested in equal installments on each of the first four anniversaries of the grant date, subject to continued service as a member of the board of directors through the applicable vesting date. All such options were exercisable as of December 31, 2015.

(b)

Reflects the number of restricted stock units with respect to our common stock granted to our non-employee directors on December 9, 2016 pursuant to the Neff Corporation 2014 Incentive Award Plan, which will vest on the earliest of: (i) the first anniversary of the grant date, (ii) the date immediate preceding the date of the next annual meeting of the Company's stockholders following the grant date and (iii) a change of control.

              We reimbursed each non-employee director for expenses incurred during 2016 in connection with his services as a director.

Narrative Disclosure to Director Compensation Table

            In connection with our IPO, we adopted a compensation policy that is applicable to all of our non-employee directors other than Mr. Deignan. Pursuant to this policy, each eligible non-employee director other than the chairperson of the Board receives an annual cash retainer of $45,000 and the chairperson receives an annual cash retainer of $80,000, payable quarterly. Each audit committee member other than the committee chairperson receives an additional annual cash retainer of $7,500 and the audit committee chairperson receives an additional annual cash retainer of $15,000. Each compensation committee member other than the committee chairperson receives an additional annual cash retainer of $5,000 and the committee chairperson receives an additional annual cash retainer of $10,000. Each nominating and corporate governance committee member other than the committee chairperson receives an additional annual cash retainer of $2,500 and the committee chairperson receives an additional annual cash retainer of $5,000. Each annual retainer is payable quarterly in arrears. There are no fees paid for Board or committee meeting attendance.

              Pursuant to our director compensation policy adopted in connection with our IPO, each year we will grant each eligible non-employee director an award of restricted stock units in our Company with a grant-date fair value of $85,000 for each non-employee director other than the chairperson of the Board of Directors and $100,000 for the chairperson. The terms of each such award will be set forth in a written award agreement between each director and us, which will generally provide for vesting after one year of continued service as a director. Directors elected or appointed mid-quarter will receive a pro-rated portion of the annual retainer and the annual award, in each case adjusted to reflect his or her period of service.

              Further, in connection with our IPO, we adopted a director stock ownership policy encouraging each director to hold shares of our common stock with a value equal to three times his or her annual cash retainer fee (exclusive of any committee retainers).

Security Ownership of Certain Beneficial Owners and Management

The Company has two classes of stock outstanding: Class A Common Stock and Class B Common Stock. Each share of Class A Common Stock entitles the registered holder thereof to one vote and each share of Class B Common Stock entitles the registered holder thereof to one vote. On March 20, 2017, the Company had outstanding 8,859,662 shares of Class A Common Stock and 14,951,625 shares of Class B Common Stock. The following table sets forth information, as of March 20, 2017, unless otherwise indicated, regarding the beneficial ownership of our Class A Common Stock and our Class B Common Stock by (i) stockholders who beneficially owned more than 5% of the outstanding shares of our Class A Common Stock and our Class B Common Stock and (ii) each of our directors (which includes all nominees), each of our Named Executive Officers and all directors and executive officers as a group. The number of shares beneficially owned by each stockholder is determined under rules issued by the SEC and includes voting or investment power with respect to securities. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of Class A Common Stock subject to options, warrants or other rights held by such person that are currently exercisable or will become exercisable within 60 days of March 20, 2017 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Unless otherwise indicated, the address of all listed stockholders is c/o Neff Corporation, 3750 N.W. 87th Avenue, Suite 400, Miami, FL 33178. Each of the stockholders listed has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

Certain Relationships and Related Person Transactions

POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

Our Board of Directors recognizes the fact that transactions with related persons present a heightened risk of conflicts of interests and/or improper valuation (or the perception thereof). Our Board of Directors has adopted a written policy on transactions with related persons that is in conformity with the requirements for companies listed on the NYSE. Under the policy:

•

any related person transaction, and any material amendment or modification to a related person transaction, must be reviewed and approved or ratified by a committee of the Board of Directors composed solely of independent directors who are disinterested or by the disinterested members of the Board of Directors; and

•

any employment relationship or transaction involving an executive officer and any related compensation must be approved by the Compensation Committee of the Board of Directors or recommended by the Compensation Committee to the Board of Directors for its approval.

In connection with the review and approval or ratification of a related person transaction:

•

management must disclose to the committee or disinterested directors, as applicable, the name of the related person and the basis on which the person is a related person, the material terms of the related person transaction, including the approximate dollar value of the amount involved in the transaction, and all the material facts as to the related person's direct or indirect interest in, or relationship to, the related person transaction;

•

management must advise the committee or disinterested directors, as applicable, as to whether the related person transaction complies with the terms of our agreements governing our material outstanding indebtedness that limit or restrict our ability to enter into a related person transaction;

•

management must advise the committee or disinterested directors, as applicable, as to whether the related person transaction will be required to be disclosed in our applicable filings under the Securities Act of 1933, as amended (the "Securities Act") or the Exchange Act, and related rules, and, to the extent required to be disclosed, management must ensure that the related person transaction is disclosed in accordance with such Acts and related rules; and

•

management must advise the committee or disinterested directors, as applicable, as to whether the related person transaction constitutes a "personal loan" for purposes of Section 402 of the Sarbanes-Oxley Act of 2002.

In addition, the related person transaction policy provides that the committee or disinterested directors, as applicable, in connection with any approval or ratification of a related person transaction involving a non-employee director or director nominee, should consider whether such transaction would compromise the director or director nominee's status as an "independent," "outside," or "non-employee" director, as applicable, under the rules and regulations of the SEC, the NYSE and the Internal Revenue Code of 1986, as amended.

The following are certain transactions, arrangements and relationships with our directors, executive officers and stockholders owning 5% or more of our outstanding Common Stock.

THE ORGANIZATIONAL TRANSACTIONS

Wayzata owns 14,951,625 common units of Neff Holdings, representing approximately 63% of Neff Holdings total outstanding membership units. Each common unit held by Wayzata or acquired by individuals upon exercise of existing options granted by Neff Holdings will be redeemable, at the election of such member, for, at Neff

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Corporation's option, newly-issued shares of Class A Common Stock on a one-for-one basis or a cash payment equal to a volume-weighted average market price of one share of Class A Common Stock for each common unit redeemed (subject to customary adjustments, including for stock splits, stock dividends and reclassifications) in accordance with the terms of the Neff Holdings LLC Agreement (as described below); provided that, at Neff Corporation's election, Neff Corporation may effect a direct exchange of such Class A Common Stock or such cash for such common units.

Wayzata, through (i) its ownership of Neff Corporation's Class B Common Stock, has approximately 63% of the combined voting power of all of Neff Corporation's Common Stock and (ii) its ownership of Neff Holdings' common units, holds approximately 63% of the economic interest in the business of Neff Holdings and its subsidiaries. Certain individuals who held pre-existing options granted by Neff Holdings have the right to acquire 757,935 common units of Neff Holdings which, if such existing options were exercised in full, would represent approximately 3.2% of the economic interest in the business of Neff Holdings and its subsidiaries on a fully diluted basis.

TAX RECEIVABLE AGREEMENT

As described above, we used substantially all of the net proceeds from the IPO to purchase common units of Neff Holdings directly from Neff Holdings. We may obtain an increase in our share of the tax basis of the assets of Neff Holdings in the future, when a Prior LLC Owner's (as defined below) right to have common units in Neff Holdings held by such Prior LLC Owner is redeemed by Neff Holdings or, at the election of Neff Corporation, exchanged (which we intend to treat as our direct purchase of common units from a Prior LLC Owner for U.S. federal income and other applicable tax purposes, regardless of whether such common units are surrendered by a Prior LLC Owner to Neff Holdings for redemption or sold to us upon the exercise of our election to acquire such common units directly) (such basis increase, the "Basis Adjustments"). Moreover, in connection with the organizational transactions described above and as a result of the application of the principles of Section 704(c) of the Code and the U.S. Treasury regulations issued thereunder, which require that items of income, gain, loss and deduction attributable to property owned by Neff Holdings on the date that we purchased common units directly from Neff Holdings with a portion of the proceeds from the IPO must be allocated among the members of Neff Holdings to take into account the difference between the fair market value and the adjusted tax basis of such assets on such date, Neff Holdings will be required to make certain special allocations of its items of loss and deduction to us over time that are in excess of our pro rata share of such items of loss or deduction. Any Basis Adjustment as well as the special allocations described above will have the effect of reducing the amounts that we would otherwise pay in the future to various tax authorities. The Basis Adjustments may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

In connection with the transactions described above, we entered into a Tax Receivable Agreement with Wayzata and the individuals who held pre-IPO options granted by Neff Holdings (collectively, our "Prior LLC Owners") on November 26, 2014 that provides for the payment by us to such persons of 85% of the amount of tax benefits, if any, that we actually realize, or in some circumstances are deemed to realize, as a result of the transactions described above, including increases in the tax basis of the assets of Neff Holdings attributable to payments made under the Tax Receivable Agreement and deductions attributable to imputed interest and other payments of interest pursuant to the Tax Receivable Agreement. Neff Holdings intends to have in effect an election under Section 754 of the Code effective for the taxable year in which we purchase common units from the Prior LLC Owners with the proceeds of the IPO and each taxable year in which a redemption or exchange of Neff Holdings common units for shares of our Class A Common Stock or cash occurs. These tax benefit payments are not conditioned upon one or more of the Prior LLC Owners maintaining a continued ownership interest in either Neff Holdings or us. Our Prior LLC Owners' rights under the Tax Receivable Agreement are assignable to transferees of its common units in Neff Holdings (other than Neff Corporation as transferee pursuant to redemption of common units in Neff Holdings). We expect to benefit from the remaining 15% of the tax benefits, if any, that we may actually realize.

34

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

The actual Basis Adjustments, as well as any amounts paid to our Prior LLC Owners under the Tax Receivable Agreement will vary depending on a number of factors, including:

•

the timing of any subsequent redemptions or exchanges—for instance, the increase in any tax deductions will vary depending on the fair value, which may fluctuate over time, of the depreciable or amortizable assets of Neff Holdings at the time of each redemption or exchange;

•

the price of shares of our Class A Common Stock at the time of the initial purchases or subsequent redemptions or exchanges—the Basis Adjustments, as well as any related increase in any tax deductions, is directly related to the price of shares of our Class A Common Stock at the time of the initial purchases or subsequent redemptions or exchanges;

•

the extent to which such redemptions or exchanges are taxable—if a redemption or exchange is not taxable for any reason, increased tax deductions will not be available; and

•

the amount and timing of our income—the Tax Receivable Agreement generally will require Neff Corporation to pay 85% of the tax benefits as and when those benefits are treated as realized under the terms of the Tax Receivable Agreement. If Neff Corporation does not have taxable income, it generally will not be required (absent a change of control or other circumstances requiring an early termination payment) to make payments under the Tax Receivable Agreement for that taxable year because no tax benefits will have been actually realized. However, any tax benefits that do not result in realized tax benefits in a given taxable year will likely generate tax attributes that may be utilized to generate tax benefits in previous or future taxable years. The utilization of any such tax attributes will result in payments under the Tax Receivable Agreement.

For purposes of the Tax Receivable Agreement, cash savings in income and franchise tax will be computed by comparing our actual income and franchise tax liability to the amount of such taxes that we would have been required to pay had there been no Basis Adjustments, had there been no tax benefit to us as a result of the special allocations described above and had the Tax Receivable Agreement not been entered into. The Tax Receivable Agreement will generally apply to each of our taxable years, beginning with 2014, the first taxable year ending after the consummation of the IPO. There is no maximum term for the Tax Receivable Agreement; however, the Tax Receivable Agreement may be terminated by us pursuant to an early termination procedure that requires us to pay the Prior LLC Owners an agreed upon amount equal to the estimated present value of the remaining payments to be made under the agreement (calculated with certain assumptions).

The payment obligations under the Tax Receivable Agreement are obligations of Neff Corporation and not of Neff Holdings. Although the actual timing and amount of any payments that may be made under the Tax Receivable Agreement will vary, we expect that the payments that we may be required to make to our Prior LLC Owners could be substantial. Any payments made by us to our Prior LLC Owners under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to us or to Neff Holdings and, to the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, the unpaid amounts will be deferred and will accrue interest until paid by us. We anticipate funding payments under the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash and available borrowings under the revolving credit facility.

The Tax Receivable Agreement provides that if certain mergers, asset sales, other forms of business combination, or other changes of control were to occur, or that if, at any time, we elect an early termination of the Tax Receivable Agreement, then the Tax Receivable Agreement will terminate and our obligations, or our successor's obligations, under the Tax Receivable Agreement would accelerate and become due and payable, based on certain assumptions, including an assumption that we would have sufficient taxable income to fully utilize all potential future tax benefits that are subject to the Tax Receivable Agreement. We may elect to completely terminate the Tax Receivable Agreement early only with the written approval of a majority of Neff Corporation's "independent directors" (within the meaning of Rule 10A-3 under the Exchange Act and the NYSE listing requirements). The

35

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

single Wayzata board member will not be an "independent director" for this purpose and will not have the ability to cause Neff Corporation to elect an early termination of the Tax Receivable Agreement.

Decisions made by us in the course of running our business, such as with respect to mergers, asset sales, other forms of business combinations or other changes in control, may influence the timing and amount of payments that are received by a redeeming Prior LLC Owner under the Tax Receivable Agreement. For example, the earlier disposition of assets following an exchange or acquisition transaction will generally accelerate payments under the Tax Receivable Agreement and increase the present value of such payments.

As a result of a change in control or our election to terminate the Tax Receivable Agreement early, (i) we could be required to make cash payments to our Prior LLC Owners that are greater than the specified percentage of the actual benefits we ultimately realize in respect of the tax benefits that are subject to the Tax Receivable Agreement, and (ii) we would be required to make an immediate cash payment equal to the present value of the anticipated future tax benefits that are the subject of the Tax Receivable Agreement, which payment may be made significantly in advance of the actual realization, if any, of such future tax benefits. In these situations, our obligations under the Tax Receivable Agreement could have a material adverse effect on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combination, or other changes of control. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that we determine. We will not be reimbursed for any cash payments previously made to our Prior LLC Owners pursuant to the Tax Receivable Agreement if any tax benefits initially claimed by us are subsequently challenged by a taxing authority and ultimately disallowed. Instead, any excess cash payments made by us to a Prior LLC Owner will be netted against any future cash payments that we might otherwise be required to make under the terms of the Tax Receivable Agreement. However, we might not determine that we have effectively made an excess cash payment to our Prior LLC Owners for a number of years following the initial time of such payment. As a result, it is possible that we could make cash payments under the Tax Receivable Agreement that are substantially greater than our actual cash tax savings. Although we are not currently aware of any potential challenge, if we subsequently determine that any Basis Adjustments or other tax benefits may be subjected to a reasonable challenge by a taxing authority, we may withhold payments to our Prior LLC Owners under the Tax Receivable Agreement related to such Basis Adjustments or other tax benefits in an interest-bearing escrow account until such a challenge is no longer possible.

If we receive a formal notice or assessment from a taxing authority with respect to any cash savings covered by the Tax Receivable Agreement, we will place any subsequent tax benefit payments that would otherwise be made to the Prior LLC Owners into an interest-bearing escrow account until there is a final determination. We will have full responsibility for, and sole discretion over, all Neff Corporation tax matters, including the filing and amendment of all tax returns and claims for refund and defense of all tax contests, subject to certain participation and approval rights held by the Prior LLC Owners.

Under the Tax Receivable Agreement, we are required to provide our Prior LLC Owners with a schedule showing the calculation of payments that are due under the Tax Receivable Agreement with respect to each taxable year with respect to which a payment obligation arises within 30 days after filing our U.S. federal income tax return for such taxable year. This calculation will be based upon the advice of our tax advisors. Payments under the Tax Receivable Agreement will generally be made to our Prior LLC Owners within three business days after this schedule becomes final pursuant to the procedures set forth in the Tax Receivable Agreement, although interest on such payments will begin to accrue at a rate of LIBOR plus 100 basis points from the due date (without extensions) of such tax return.

Any late payments that may be made under the Tax Receivable Agreement will continue to accrue interest at LIBOR plus 500 basis points until such payments are made, generally including any late payments that we may subsequently make because we did not have enough available cash to satisfy our payment obligations at the time at which they originally arose.

36

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

For the year ended December 31, 2016, we did not make any payments under the Tax Receivable Agreement.

The foregoing are merely estimates, and the actual payments and timing of such payments could differ materially depending on a number of factors. As discussed above, actual amounts of payments under the Tax Receivable Agreement and the timing of such payments will vary and will be determined based on a number of factors, including the timing of future redemptions or exchanges of common units in Neff Holdings, the price of Class A Common Stock at the time of each redemption or exchange, the extent to which such redemptions or exchanges are taxable, the amount and timing of the taxable income we generate in the future and the tax rate then applicable and the timing and amount of any subsequent asset dispositions. Thus, it is likely that future transactions or events could increase or decrease the actual tax benefits realized and the corresponding payments under the Tax Receivable Agreement as compared to the estimates set forth above.

NEFF HOLDINGS LLC AGREEMENT

In connection with the completion of our IPO, Neff Corporation and the Prior LLC Owners entered into Neff Holdings' second amended and restated limited liability company agreement, which we refer to as the "Neff Holdings LLC Agreement."

Appointment as Manager.    Under the Neff Holdings LLC Agreement, Neff Corporation is a member and the sole manager of Neff Holdings. As the sole manager, Neff Corporation controls all of the day-to-day business affairs and decision-making of Neff Holdings without the approval of any other member. As such, Neff Corporation, through its officers and directors, is responsible for all operational and administrative decisions of Neff Holdings and the day-to-day management of Neff Holdings' business. Pursuant to the terms of the Neff Holdings LLC Agreement, Neff Corporation cannot, under any circumstances, be removed as the sole manager of Neff Holdings except by its election.

Compensation.    Neff Corporation will not be entitled to compensation for its services as manager. Neff Corporation will be entitled to reimbursement by Neff Holdings for fees and expenses incurred on behalf of Neff Holdings, including all expenses associated with the IPO and maintaining its corporate existence.

Distributions.    The Neff Holdings LLC Agreement will require "tax distributions" to be made by Neff Holdings to its members, as that term is defined in the agreement. Tax distributions will be made as and when members are required to make estimated payments or file tax returns, which we expect will be approximately on a quarterly basis, to each member of Neff Holdings, including Neff Corporation, based on such member's allocable share of the taxable income of Neff Holdings and an assumed tax rate that will be determined by Neff Corporation. For this purpose, the taxable income of Neff Holdings, and Neff Corporation's allocable share of such taxable income, shall be determined without regard to any tax basis adjustments that result from Neff Corporation's deemed or actual purchase of an equity interest in Neff Holdings from the Prior LLC Owners or the use of the proceeds from the IPO to repay certain indebtedness of Neff Holdings. The assumed tax rate that we expect to use for purposes of determining tax distributions from Neff Holdings to its members will approximate our reasonable estimate of the highest combined federal, state, and local tax rate that may potentially apply to any one of Neff Holdings' members, regardless of the actual final tax liability of any such member. Tax distributions will also be made only to the extent all distributions from Neff Holdings for the relevant period were otherwise insufficient to enable each member to cover its tax liabilities as calculated in the manner described above. The Neff Holdings LLC Agreement will also allow for distributions to be made by Neff Holdings to its members on a pro rata basis out of "distributable cash," as that term is defined in the agreement. We expect Neff Holdings may make distributions out of distributable cash periodically to the extent permitted by Neff Corporation's credit facilities and necessary to enable Neff Corporation to cover its operating expenses and other obligations, including tax liability and obligations under the Tax Receivable Agreement, as well as to make dividend payments, if any, to the holders of its Class A Common Stock.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Transfer Restrictions.    The Neff Holdings LLC Agreement generally does not permit transfers of common units by members, subject to limited exceptions. Any transferee of common units must assume, by operation of law or written agreement, all of the obligations of a transferring member with respect to the transferred units, even if the transferee is not admitted as a member of Neff Holdings.

Recapitalization.    The Neff Holdings LLC Agreement recapitalized the Class A units previously held by the existing members of Neff Holdings, as well as the Class B units underlying certain options outstanding under the 2010 Option Plan, into a new single class of common units of Neff Holdings. The Neff Holdings LLC Agreement also reflected a split of common units such that one common unit could be acquired with the net proceeds received in the initial offering from the sale of one share of our Class A Common Stock, after the deduction of underwriting discounts and commissions. As a result of such conversion into common units and split:

•

the 9,200,000 Class A units held by Wayzata in Neff Holdings prior to the effectiveness of the Neff Holdings LLC Agreement were converted into an aggregate of 14,951,625 common units in Neff Holdings, and

•

the outstanding options over 778,374 Class B units in Neff Holdings prior to the effectiveness of the Neff Holdings LLC Agreement were converted into options over an aggregate of 1,264,985 common units in Neff Holdings, and the exercise price of those options was adjusted from $10.82 per unit to $6.66 per unit,

in each case reflecting a split of approximately 1.625-for-one of each Class A unit and each Class B unit, subject to rounding.

Common Unit Redemption Right.    The Neff Holdings LLC Agreement provides a redemption right to the Prior LLC Owners and the holders of options over common units in Neff Holdings which entitles them to have their common units redeemed by Neff Holdings, at the election of each such person, for, at our option, newly-issued shares of our Class A Common Stock on a one-for-one basis or a cash payment equal to a volume weighted average market price of one share of Class A Common Stock for each common unit redeemed (subject to customary adjustments, including for stock splits, stock dividends and reclassifications). If we decide to make a cash payment, the member has the option to rescind its redemption request within a specified time period. Upon the exercise of the redemption right, the redeeming member will surrender common units to Neff Holdings for cancellation. The Neff Holdings LLC Agreement requires that we contribute cash or shares of our Class A Common Stock to Neff Holdings in exchange for an amount of newly issued common units in Neff Holdings to us equal to the number of common units redeemed by the member. Neff Holdings will then distribute the cash or shares of our Class A Common Stock to the redeeming member to complete the redemption. At our election, we may effect a direct exchange of cash or our Class A Common Stock for such common units in lieu of such a redemption. Neither Neff Corporation nor Neff Holdings can compel any member to tender their common units for redemption by Neff Holdings or to directly exchange such common units with Neff Corporation. However, once a member tenders its common units for redemption, Neff Corporation, in its sole discretion, will determine at such time whether to contribute cash or shares to Neff Holdings to complete the redemption or to effect a direct exchange with such redeeming member. Whether by redemption or exchange, we are obligated to ensure that at all times the number of common units in Neff Holdings that we own equals the number of our outstanding shares of Class A Common Stock. To the extent Neff Corporation, in its discretion, elects to contribute shares of Class A Common Stock to Neff Holdings to complete a redemption, Neff Holdings will issue to Neff Corporation in respect of such contribution an equal number of common units of Neff Holdings, which transaction will maintain the one-to-one ratio. To the extent Neff Corporation, in its discretion, elects to effect a direct exchange with the redeeming member to complete a redemption, Neff Corporation will issue to such redeeming member a number of shares of Class A Common Stock equal to the number of common units of Neff Holdings delivered by such redeeming member to Neff Corporation in such exchange, which transaction will maintain the one-to-one ratio.

Maintenance of One-to-One Ratio between Shares of Class A Common Stock and Common Units.    The Neff Holdings LLC Agreement requires Neff Holdings to take all actions with respect to its common units, including

38

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

reclassifications, distributions, divisions or recapitalizations, to maintain at all times a one-to-one ratio between the number of common units owned by us and the number of shares of our Class A Common Stock outstanding. This ratio requirement disregards (i) shares of our Class A Common Stock under unvested options issued by us, (ii) treasury stock and (iii) preferred stock or other debt or equity securities (including warrants, options or rights) issued by us that are convertible into or exercisable or exchangeable for shares of Class A Common Stock, except to the extent we have contributed the net proceeds from such other securities, including any exercise or purchase price payable upon conversion, exercise or exchange thereof, to the equity capital of Neff Holdings. In addition, this Class A Common Stock ratio requirement disregards all common units at any time held by any other person, including our existing members and the holders of options over common units. If we issue, transfer or deliver from treasury stock or repurchase shares of Class A Common Stock in a transaction not contemplated by the Neff Holdings LLC Agreement, we as manager have the authority to take all actions such that, after giving effect to all such issuances, transfers, deliveries or repurchases, the number of outstanding common units we own equals, on a one-for-one basis, the number of outstanding shares of Class A Common Stock. If we issue, transfer or deliver from treasury stock or repurchase or redeem any of our preferred stock in a transaction not contemplated by the Neff Holdings LLC Agreement, we as manager have the authority to take all actions such that, after giving effect to all such issuances, transfers, deliveries repurchases or redemptions, we hold (in the case of any issuance, transfer or delivery) or cease to hold (in the case of any repurchase or redemption) equity interests in Neff Holdings which (in our good faith determination) are in the aggregate substantially equivalent to our preferred stock so issued, transferred, delivered, repurchased or redeemed. Neff Holdings is prohibited from undertaking any subdivision (by any split of units, distribution of units, reclassification, recapitalization or similar event) or combination (by reverse split of units, reclassification, recapitalization or similar event) of the common units that is not accompanied by an identical subdivision or combination of our Class A Common Stock to maintain at all times a one-to-one ratio between the number of common units owned by us and the number of outstanding shares of our Class A Common Stock, subject to exceptions.

Issuance of Common Units Upon Exercise of Options or Issuance of Other Equity Compensation.    Upon the exercise of options issued by us (as opposed to options issued by Neff Holdings), or the issuance of other types of equity compensation by us (such as the issuance of restricted or non-restricted stock, payment of bonuses in stock or settlement of stock appreciation rights in stock), we will have the right to acquire from Neff Holdings a number of common units equal to the number of our shares of Class A Common Stock being issued in connection with the exercise of such options or issuance of other types of equity compensation. When we issue shares of Class A Common Stock in settlement of stock options granted to persons that are not officers or employees of Neff Holdings or its subsidiaries, we will make, or be deemed to make, a capital contribution in Neff Holdings equal to the aggregate value of such shares of Class A Common Stock and Neff Holdings will issue to us a number of common units equal to the number of shares we issued. When we issue shares of Class A Common Stock in settlement of stock options granted to persons that are officers or employees of Neff Holdings or its subsidiaries, then we will be deemed to have sold directly to the person exercising such award a portion of the value of each share of Class A Common Stock equal to the exercise price per share, and we will be deemed to have sold directly to Neff Holdings (or the applicable subsidiary of Neff Holdings) the difference between the exercise price and market price per share for each such share of Class A Common Stock. In cases where we grant other types of equity compensation to employees of Neff Holdings or its subsidiaries, on each applicable vesting date we will be deemed to have sold to Neff Holdings (or such subsidiary) the number of vested shares at a price equal to the market price per share, Neff Holdings (or such subsidiary) will deliver the shares to the applicable person, and we will be deemed to have made a capital contribution in Neff Holdings equal to the purchase price for such shares in exchange for an equal number of common units of Neff Holdings.

Dissolution.    The Neff Holdings LLC Agreement will provide that the unanimous consent of all members holding voting units will be required to voluntarily dissolve Neff Holdings. In addition to a voluntary dissolution, Neff Holdings will be dissolved upon a change of control transaction under certain circumstances, as well as upon the

39

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

entry of a decree of judicial dissolution or other circumstances in accordance with Delaware law. Upon a dissolution event, the proceeds of a liquidation will be distributed in the following order: (i) first, to pay the expenses of winding up Neff Holdings; (ii) second, to pay debts and liabilities owed to creditors of Neff Holdings, other than members; (iii) third, to pay debts and liabilities owed to members; and (iv) fourth, to the members pro-rata in accordance with their respective percentage ownership interests in Neff Holdings (as determined based on the number of common units held by a member relative to the aggregate number of all outstanding common units).

Confidentiality.    Each member will agree to maintain the confidentiality of Neff Holdings' confidential information. This obligation excludes information independently obtained or developed by the members, information that is in the public domain or otherwise disclosed to a member, in either such case not in violation of a confidentiality obligation or disclosures required by law or judicial process or approved by our chief executive officer.

Indemnification.    The Neff Holdings LLC Agreement provides for indemnification of the manager, members and officers of Neff Holdings and their respective subsidiaries or affiliates.

REGISTRATION RIGHTS AGREEMENT

We entered into a Registration Rights Agreement with our Prior LLC Owners on November 26, 2014. The Registration Rights Agreement provides our Prior LLC Owners certain registration rights whereby, at any time following the IPO and the expiration of any related lock-up period, they can require us to register under the Securities Act shares of Class A Common Stock issuable to them, at our election, upon redemption or exchange of their common units in Neff Holdings (including common units issuable upon exercise of options issued by Neff Holdings). The related lock-up period has expired. The Registration Rights Agreement also provides for piggyback registration rights for all stockholders that are parties to the agreement.

OTHER COMPENSATION PROGRAMS

Neff Holdings has entered into certain compensation plans to provide payments to certain of its service providers (including its named executive officers and certain of our non-employee directors) as described above under "Executive and Director Compensation."

INDEMNIFICATION AGREEMENTS AND ASSUMPTION AGREEMENT

Our Amended and Restated Bylaws provide that we will indemnify our directors and officers to the fullest extent permitted by the Delaware General Corporation Law, subject to certain exceptions contained in our Amended and Restated Bylaws. In addition, our Amended and Restated Certificate of Incorporation provides that our directors will not be liable for monetary damages for breach of fiduciary duty.

We have entered into indemnification agreements with each of our executive officers and directors. The indemnification agreements provide the executive officers and directors with contractual rights to indemnification, and expense advancement and reimbursement, to the fullest extent permitted under the Delaware General Corporation Law, subject to certain exceptions contained in those agreements.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and stockholders who beneficially own more than 10% of any class of our equity securities registered pursuant to Section 12 of the Exchange Act (collectively, the "Reporting Persons") to file initial statements of beneficial ownership of securities and statements of changes in beneficial ownership of securities with respect to our equity securities with the SEC. All Reporting Persons are required by SEC regulation to furnish us with copies of all reports that such Reporting Persons file with the SEC pursuant to Section 16(a). Based solely on our review of the copies of such forms received by us and upon written representations of the Reporting Persons received by us, we believe that there has been compliance with all Section 16(a) filing requirements applicable to such Reporting Persons with respect to the fiscal year ended December 31, 2016 except for (i) Mr. Continenza who filed one late report regarding two transactions; (ii) Mr. Holthaus who filed one late report regarding two transactions; (iii) Mr. Sileck who filed one late report regarding two transactions; and (iv) Mr. Singer who filed one late report regarding two transactions required by Section 16(a).

Compensation Committee Interlocks and Insider Participation

None of the members of our Compensation Committee were employees of the Company during the fiscal year ended December 31, 2016. None of the members of our Compensation Committee formerly served as an officer of the Company. None of our executive officers served as a director or a member of a compensation committee (or other committee serving an equivalent function) of any other entity, one of whose executive officers served as a director or member of our Compensation Committee during the fiscal year ended December 31, 2016.
