Q:  How do I vote my shares?

A: Shareholders of record may vote using one of the following four methods:
over the Internet, which you are encouraged to do so if you have access to the Internet;
by telephone;
by completing, signing and returning the included proxy card, for those who requested to receive printed proxy materials in the mail; or
by attending the Annual Meeting and voting in person.

The Notice provides instructions on how to access your proxy, which contains instructions on how to vote via the Internet or by telephone. For shareholders who request to receive a paper proxy card in the mail, instructions for voting via the Internet, by telephone or by mail are set forth on the proxy card.

If you hold shares in street name, the organization holding your account is considered the shareholder of record for purposes of voting at the Annual Meeting. The shareholder of record will provide you with instructions on how to vote your shares. Internet and telephone voting will be offered to shareholders owning shares through most brokerage firms and banks. Additionally, if you would like to vote in person at the Annual Meeting, contact the brokerage firm, bank or other nominee who holds your shares to obtain a proxy from them and bring it with you to the Annual Meeting. You will not be able to vote at the Annual Meeting unless you have a proxy from your brokerage firm, bank or other nominee.

Q:  What is the difference between holding shares as a shareholder of record and as a beneficial owner?

A:Most of our shareholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. There are some important distinctions between shares held of record and those owned beneficially.

Shareholder of Record

If your shares are registered in your name with our transfer agent, Computershare, you are the shareholder of record for those shares and are receiving proxy-related materialsMeeting Materials directly from us. As the shareholder of record, you have the right to grant your voting proxy directly to us or to vote in person at the meeting.

Beneficial Owner

If your shares are held in a stock brokerage account, by a bank or other nominee (commonly referred to as being held in “street name”), you are the beneficial owner of those shares. Your broker, bank or nominee is the shareholder of record and therefore has forwarded proxy-related materialsMeeting Materials to you as beneficial owner. As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares and are also invited to attend the meeting. However, since you are not the shareholder of record, you may not vote your shares in person at the meeting unless you obtain a signed proxy from your broker, bank or nominee giving you the right to vote the shares.

Q:  How do I vote if I am a shareholder of record (as described in the question and answer above)?

A: You can vote on the Internet or by telephone by following the instructions you received in the mail or by email. If you received a full printed set of our proxy materials in the mail, you can also vote by mail by signing and returning the proxy card provided with those materials. Finally, you can vote in person at the meeting.

Q:  How do I vote if I am a beneficial owner (as described in the question and answer above)?

A: You can vote on the Internet or by telephone by following the instructions you received in the mail or by email. If you received a full printed set of our proxy materials in the mail, you can also vote by mail. You can vote in person at the meeting only if you obtain a signed proxy from your broker, bank or nominee giving you this right.

Q:  Can I change my vote or revoke my proxy?

A:Yes. You can change your vote or revoke your proxy at any time before the final vote at the meeting. You can do this by casting a later proxy through any of the available methods described in the questions and answers above. If you are a shareholder of record, you can also revoke your proxy by delivering a written notice of your revocation to our Corporate Secretary at our principal executive office at 508 West Wall Street,404 Veterans Airpark Lane, Suite 550,300, Midland, Texas 79701.79705. If you are a beneficial owner, you can revoke your proxy by following the instructions sent to you by your broker, bank or other nominee.



Q:  What does it mean if I get more than one set of proxy-related materials?Meeting Materials?

A:It means you hold shares registered in more than one account. Follow the instructions in each set of proxy-related materialsMeeting Materials to ensure that all of your shares are voted.

Q:  What is the quorum requirement for the meeting?

A:For a “quorum” to exist at the meeting, shareholders holding a majority of the votes entitled to be cast by the shareholders entitled to vote must be present in person or represented by proxy at the meeting. There must be a quorum for any action to be taken at the meeting (other than adjournment or postponement of the meeting). If you submit a properly completed proxy, even if you abstain from voting, then your shares will be counted for purposes of determining the presence of a quorum.

If a broker indicates on a proxy that it lacks discretionary authority as to certain shares to vote on a particular matter, commonly referred to as “broker non-votes,” those shares will still be counted for purposes of determining the presence of a quorum at the meeting.  Please see the next question and answer for further information about "broker non-votes."

Q:  What are broker non-votes and how are broker non-votes and abstentions counted?

A: If you are a beneficial owner and hold your shares in street name and do not provide your broker or other nominee with voting instructions, the broker, bank, or other nominee will determine if it has the discretionary authority to vote on the particular matter. The New York Stock Exchange permits brokers to vote their customers' shares on routine matters when the brokers have not received voting instructions from the customers. The ratification of independent public accountants is an example of a routine matter on which brokers may vote. Brokers may not vote their customers' shares on non-routine matters unless they have received instructions from the customers. Non-voted shares on non-routine matters are referred to as broker non-votes. The ratification of the appointment of BDO USA,Moss Adams LLP as our independent public accountants for 20162021 (Proposal 4)3) is a matter considered "routine" under applicationapplicable rules. The election of one directortwo Directors (Proposal 1), and the advisory vote to approve the named executive officersofficers' compensation programs (Proposal 2), the approval of the amendment and restatement of the 1998 Stock Option Plan (Proposal 3) and the amendment to the Company’s Bylaws to implement a majority voting standard in uncontested election of Directors (Proposal 5)are matters considered "non-routine" under applicable rules. A broker or other nominee cannot vote without instructions on non-routine matters. AbstentionsFor purposes of the election of a Director and all of the proposals set forth in this proxy statement, abstentions and broker non-votes, if any, will not be counted as votes cast and will have no effect on Proposal 1, as the electionresult of the vote, although they will be considered present for the purpose of determining the presence of a Director is determined by counting the votes actually cast where abstentions and broker non-votes are not treated as votes cast. With respect to the advisory vote to approve the named executive officers compensation programs (Proposal 2), the approval of the 1998 Stock Option Plan amendment and restatement (Proposal 3) and the amendment to the Bylaws (Proposal 5) where the vote required is a majority of votes present and entitled to vote, abstentions will be equivalent to a vote cast against the proposals and broker non-votes will have no effect.quorum.

We also will consider any other business that properly comes before the votes cast at the Annual Meeting. This means that the nominee for election as Director who receives the greatest number of votes cast in favor of his or her election will be elected to the Board of Directors. The advisory vote on the compensation programs of our named executive officers, the amendment and restatement of the 1998 Stock Option Plan, ratification of the appointment of BDO USA, LLP as the Company’s independent registered public accounting firm, and the amendment to the Bylaws to implement a majority voting standard in the uncontested election of Directors are approved if the votes cast in favor of the matter exceed the votes cast against the matter. If you are a beneficial owner and do not provide the shareholder of record with voting instructions, your shares may constitute broker non-votes for certain matters (as described in the question and answer immediately above). In tabulating the voting result for a proposal, shares that constitute broker non-votes are not considered as being entitled to vote on that proposal.annual meeting.

Q:  How can I vote on each of the matters and how will the votes be counted?

A: In the election of directors,Directors, you may vote “FOR,” “AGAINST,” or “ABSTAIN” with respect to theeach nominee. If you elect to abstain from the election of directors, the abstention will not have any effect on the election of directors. In tabulating the voting results for the election of directors, only “FOR” and “AGAINST” votes are counted.

For the (i) advisory vote on compensation of our named executive officers, (ii) approval ofand the amendment and restatement of the 1998 Stock Option Plan, (iii)(ii) ratification of the appointment of BDO USA,Moss Adams LLP as our independent auditors and (iv) the amendment to the Bylaws to implement a majority voting standard in the uncontested election of Directors, you may vote “FOR,” “AGAINST,”


or “ABSTAIN” with respect to these fourtwo proposals. If you electUnder Colorado law (under which the Company is incorporated), abstentions are counted as shares present and entitled to abstain from votingvote at the Annual Meeting, and therefore counted as present for the purpose of determining whether a quorum is present, but they are not counted as shares cast and will therefore have no effect on anythe outcome of these proposals, the abstention will have the same effect as an “AGAINST” vote with respect to such proposal.vote.

If you sign and return your proxy card or voting instruction form without giving specific voting instructions, your shares will be voted as recommended by our Board. If you are a beneficial holder and do not return a voting instruction form, your broker may only vote on the ratification of the appointment of BDO USA, LLPMoss Adams (Proposal 4)3).

Q:  Who will count the votes?

A:Broadridge, an international investor relations company, is assisting us with the voting of proxies for our meeting. Prior to the meeting, Broadridge will provide us with a tabulation of the votes cast prior to the meeting. We believe that Broadridge will use procedures that are consistent with Colorado law concerning the voting of shares, the determination of the presence of a quorum and the determination of the outcome of each matter submitted for a vote. In addition, we will appoint a voting inspector at the meeting to count and tabulate any votes cast at the meeting.

Q:  Who may attend the meeting?

A:All shareholders as of the Record Date may attend. Please bring to the meeting:

proof of ownership such as: a copy of your proxy or voting instruction card; the two-page notice regarding the internet availability of proxy materials you received in the mail; or a copy of a brokerage or bank statement showing your share ownership as of the Record Date; and
proofof identification such as a valid driver’s license or passport.

Q:  How will voting on any other business be conducted?

A:We do not expect any matters to be presented for a vote at the meeting other than the fivefour matters described in this proxy statement. If you grant a proxy, either of the officers named as proxy holders, Stephen C. Taylor and G. Larry Lawrence,John W. Chisholm, or their nominees or substitutes, will have the discretion to vote your shares on any additional matters that are properly presented for a vote at the meeting and at any adjournment or postponement that may take place. If, for any unforeseen reason, our nominee is not available as a candidate for director,Director, the persons named as the proxy holder will vote your proxy for another candidate or other candidates nominated by our Board.

On request, we will reimburse brokers and other persons representing beneficial owners of shares for their reasonable expenses in forwarding these materials to beneficial owners.



Q:  How can I find out the results of the voting at the Annual Meeting?

The skills and backgrounds collectively represented on the Board should reflect the diverse nature of the business environment in which the Company operates. As new members of the Board are considered, diversity considerations should include - but not be limited to - business expertise, geography, age, gender and ethnicity.

ability to execute on both our short-term and long-term strategies necessary for the challenging marketplace in which we compete.  The independent directorsDirectors believe that Mr. Taylor's detailed and in-depth knowledge of the issues, opportunities and challenges facing us and our business make him the best qualified directorDirector to develop agendas that ensure that the Board’s time and attention are focused on the most critical matters.  Further, as the individual with primary responsibility for managing day-to-day operations, Mr. Taylor is best positioned to chair regular Board meetings and ensure that key business issues and risks are brought to the attention of our Board and/or Audit Committee.

These safeguards include:

All members of the Board are independent directorsDirectors except for Mr. Taylor.

As noted above, these committees meet frequently.
Review and determination of Mr. Taylor’s compensation and performance remains within the purview of the Compensation Committee.
The independent directorsDirectors continue to meet in executive sessions without management present to discuss the effectiveness of the company’s management, the quality of the Board meetings and any other issues and concerns.

Lead Director

The full Board is also responsible for reviewing our strategy, business plan, and capital expenditure budget.    
 

Our Board committees assist the Board in fulfilling its oversight responsibilities in certain areas of risk.  Our Audit Committee serves an important role in providing risk oversight, as further detailed in its charter. One of the Audit Committee’s primary duties and responsibilities is to monitor the integrity of our financial statements, financial reporting processes, systems of internal controls regarding finance,accounting, and disclosure controls and procedures. The Compensation Committee assists the Board with risk management relating to our compensation policies and programs, and the Governance and Nominating Committee assists with risk management relating to Board organization, membership and structure, succession planning for our directorsDirectors and executive officers, and corporate governance.

The Compensation Committee considers

During 2020, due to the annual stockholders advisory vote,COVID-19 pandemic, direct person-to-person meetings with shareholders were limited. However, through virtual road shows, conference calls, and video meetings, we were able to meet with nearly all of our largest institutional shareholders, including multiple touch points with many. In addition, we held virtual road shows, conference calls and video meetings with other current and prospective shareholders. These meetings not only allowed the Company to communicate about its current business operations with shareholders, the Company used these meetings to actively solicit shareholders’ views on key corporate governance issues including executive compensation as well as other stockholder input, when reviewingthe Company’s Environmental, Social and Governance (“ESG”) initiatives We have incorporated this feedback into both our compensation and ESG programs.

Overall, the Company engages our shareholders on a regular basis. In addition to periodic reports filed with the U.S. Securities and Exchange Commission, the Company holds quarterly conference calls to discuss interim financial and operational results with its stakeholders, participates in several industry conferences which are available to Company stakeholders in person (temporarily suspended due to the COVID-19 pandemic) or via various public online platforms and meets with shareholders in person throughout the year (also temporarily suspended due to the COVID-19 pandemic and public health considerations). The Company believes that its consistent and continuous shareholder engagement strategy has created an environment in which shareholders are comfortable in providing candid feedback and critique of the Company’s operations, governance and executive compensation programs, principlespolicies.

Additionally, independent Directors have taken a proactive approach in participating in shareholder engagement efforts resulting from feedback received from shareholders and policies.
As a result of critiques of our executive compensation plan and the resultingproxy advisory vote on our executive compensation structure, we directly engaged key institutional shareholders in a number of ways including supplemental proxy materials providing additional descriptive information on our overall executive compensation structure. In addition, since our last Annual Meeting,services. Independent Directors continue to regularly review the Company’s executive management has directly engaged manyshareholder outreach and communication programs and participate as appropriate.

In addition, our innovation in product design and service delivery systems is postedintended to support the sustainability goals and initiatives of our customers.

    The design and construction of our new corporate headquarters in Midland is an example of our commitment to environmental stewardship. Our state-of-the art headquarters include the use of “daylight harvesting” technologies; “smart lighting” that use artificial intelligence to determine office occupancy times and adjust light accordingly; and advanced mechanical systems including variable refrigerant flow systems and energy recovery systems; and high-performance glass and advanced solar shades that reduce glare and heat gain. These are significant capital investments for a company our size that will have a long-term impact on our website at environmental footprint.

    In addition, we strive to continuously improve the environmental footprint of our Code by requestingcore compression equipment and services with new technology and innovations that focus on best-in-class emissions and impact on the environment. Recent innovations include:

• We have and continue to pursue the most energy efficient and emissions-controlled engine systems available for our compression equipment. All of our engines have the latest catalytic technology and air-fuel ratio (AFR) controllers to provide the cleanest fuel burn available, well exceeding EPA standards. These advanced systems continuously monitor multiple engine and compressor parameters to ensure optimum engine emissions efficiencies and adjust to varying fuel quality available from wellhead production.
• To ensure consistent efficient engine performance, we have invested in state-of-the-art emissions detection equipment to ensure our engines exceed all state and federal air emissions regulations. Additionally, we perform preventative maintenance on all engine systems twice per quarter and comprehensive emissions tests to ensure optimum performance. The company is acutely focused on reducing our environment impact on noise, emissions and carbon footprint.
Our compressor units are equipped with advanced safety and containment features that provide for safe containment and disposal of used oils, antifreeze and other fluids. Skid containment rails and fluid dumps are manifolded together to mitigate the risk of fluid spills and environmental leaks as a copyresult of operating error or system failures. Active monitoring systems provide further assurance of safe and optimal operations.
In our mechanical compression packages, we have meaningfully reduced our oil consumption and associated disposal issues with a unique engine and compressor lubricating system.
In our flaring business, we have designed and exclusively sell “Quad O” flare systems which meet the most stringent federal standards, allowing our customers to exceed all emission standards when natural gas flaring is necessary.

In our Michigan service location, we have installed two oil burner systems which allows us to efficiently recycle waste oil into energy and heat capacity for our service facility.
We also work with our customers and suppliers toward policies and processes that reduce the environmental impact of our work. We continuously engage with our top customers to share best practices, new technologies and operating innovations that can be implemented to improve our collective environmental footprint.
We completed construction of our new corporate headquarters in writing at 508 West Wall Street, Suite 550, Midland, Texas 79701 or by calling us at (432) 262-2700.where we incorporated the latest energy-efficient technologies designed for commercial buildings.

Our Governance Initiatives

    The recent creation of the Environmental, Social and Governance and Personnel Development Committee of the Board of Directors is an important step and indication of the Company’s commitment to continuous improvement in corporate governance and responsibility.

This committee was chartered to be proactive in assisting the Board and Company leadership in its oversight of ESG-related policies and issues affecting Natural Gas Services Group, its stockholders, employees, customers and the communities in which the Company operates. We believe that the integration of our environmental and social initiatives with our governance responsibilities is the best way to optimize our commitment to being an industry leader in corporate responsibility.

In addition to the Board ESG Committee, our audit committee is engaged in independently reviewing the Company’s financial governance practices for accuracy and transparency as well as ensuring they provide the Company stakeholders with a consistent method by which to evaluate performance. In connection with this responsibility, in 2020 the Audit Committee received proposals from independent accounting firms and engaged a new independent auditor to perform our annual audit and quarterly reviews. The committee is satisfied this change stands in support of best governance practices.

While qualifying as a smaller reporting company with fewer disclosure requirements, the Board of Directors and leadership of the Company nonetheless have continued to provide an array of disclosures and reports as it remains committed to accurately maintaining our accounting records under generally accepted accounting principles and timely filing our periodic reports.

Our Code also contains procedures for our employees to report, anonymously or otherwise, violationsa high level of transparency, a practice it believes is in the best interests of the Code.Company’s shareholders and other stakeholders.

EXECUTIVE COMPENSATION



Compensation DiscussionEXECUTIVE COMPENSATION

In June 2018, the Securities and Analysis

Compensation DiscussionExchange Commission (“SEC”) approved amendments to the definition of a “smaller reporting company” (SRC) which became effective in September 2018. These amendments greatly expanded the number of companies that qualify as SRCs and Analysis

Thisthereby are eligible to use scaled down disclosures in their SEC filings and reports. For 2020, Natural Gas Services Group, Inc. meets the definition of an SRC. One of the significant SRC benefits is a reduction in the amount of executive compensation disclosure, including deletion of the requirement to provide the compensation, discussion and analysis section our annual proxy statement. Nevertheless, we are cognizant that our compensation disclosure provides important information to our shareholders and have elected to continue with our customary executive compensation disclosures. We believe the following disclosure provides transparency regarding our compensation policies and practices so that our shareholders can make informed decisions and knowledgeably participate in the governance process. As in the past, we intend to continue to engage our shareholders regarding our compensation policies.

This section provides information regarding our executive compensation program in 20152020 for the following executive officers of the Company (collectively, the "named executive officers").:

Stephen C. Taylor, our Chairman, President, and Chief Executive Officer;
G. Larry
James R. Lawrence, our former Vice President and Chief Financial Officer; and

James R. Hazlett, our Vice President-Technical Services.Services; and

G. Larry Lawrence, our interim Chief Financial Officer (as well as our former Vice President and Chief Financial     
Officer).

Introduction and Overview

The Compensation Committee or, the “Committee,” of the Board of Directors is responsible for determining the types and amounts of compensation we pay to our executives. The Compensation Committee operates under a written charter that you can view on our website at www.ngsgi.com.www.ngsgi.com. The Board of Directors has determined that each member of the Compensation Committee meets the independence and financial literacy requirements of the New York Stock Exchange NYSE. The Board determines, in its business judgment, whether a particular Director satisfies the requirements for membership on the Compensation Committee set forth in the Compensation Committee’s charter. None of the members of the Compensation Committee are current or former employees of Natural Gas Services Group.Group or any of its subsidiaries.


The Compensation Committee is responsible for formulating and administering our overall compensation principles and plans. This includes establishing the compensation paid to our CEO, meeting and consulting with our CEO to establish the compensation paid to our other executive officers, counseling our CEO as to different compensation approaches, administering our stock equity plans, monitoring adherence to our compensation philosophy and conducting an annual, and sometimes more frequent, reviewinterim, reviews of our compensation programs and philosophy regarding executive compensation.

The Compensation Committee periodically meets in executive session without members of management or management Directors present and reports to the Board of Directors on its actions and recommendations. The Compensation Committee, from time-to-time, also engages compensation consultants and other experts to provide data and guidance on appropriate compensation practices, industry standards, peer selection and other items relevant to the responsibilities and deliberations of the Compensation Committee.

Compensation Philosophy and Objectives

Our compensation philosophy is to provide an executive compensation program that:

rewards performance and skills necessary to advance our objectives and further the interests of our shareholders;
is fair and reasonable and appropriately applied to each executive officer;
is competitive with compensation programs offered by our competitors;competitors and industry peers; and
serves as an adequate retention tool in a competitive market.market with a finite number of experienced and qualified executives.

18





The overall objectives of our compensation philosophy are to:

provide a competitive level of current annual income that attracts and retains qualified executives at a reasonable cost to us;
retain and motivate executives to accomplish our company goals;goals and uphold and model our company ethics, values and other standards for the Natural Gas Services Group community, including those that stand in support of our ESG principles and initiatives;
provide long-term incentive compensation opportunities at levels appropriate for the respective responsibilities and performance of each executive;
align compensation and benefits with our business strategies, and goals;goals and other values and standards;
encourage the application of a decision making process that takes into account both short-term and long-term risks and the sometimesoftentimes volatile nature of our industry; and
align the financial interests of our executives with those of our shareholders through the potential grant of equity based rewards.equity-based awards and consider the impact of equity-based awards on shareholders and, where appropriate, consider alternatives to equity-based awards to avoid unnecessary shareholder dilution.



Our Compensation Committee supports these objectives by emphasizing compensation arrangements that we believe are reasonable, and will attract and retain qualified executives, and will reward them for their efforts to further our long-term growth and success. At the same time, we remain cognizant of and aim to balance our executive compensation arrangements with the interests and concerns of our shareholders.

    Note Concerning Unique 2020 Considerations: The global COVID-19 pandemic had unexpected impacts on the economy, our industry and our business. While we were able to provide a full array of products and services to our customers, the impact of the pandemic significantly altered the way in which we conducted business and severely disrupted commercial relationships with both customers and vendors. The Compensation Committee recognized the fact such changes had a material impact on the workload on and effort required of our executive leadership team to manage our operations. As such, the Compensation Committee took these extraordinary circumstances, the impact of such on our business and financial performance and the adjustments required of our executives as a result into account when assessing performance and appropriate compensation for 2020.

We have chosen to implement a relatively streamlined compensation framework for our executives.  We feel that our compensation philosophies and practices are appropriate given our relatively small size asfor a public company. By continuingcompany of our size. This streamlined framework allows the Company and Compensation Committee to maintain a relatively streamlined compensation framework for our executives, we believe that we are able to establish a higherhigh degree of transparency, understanding andas well as relative certainty for our executives as well asand our shareholders and prospective investors, while minimizing the investing public, while at the same time avoidingimpact of complex benefit packagesprograms that are both costly and agreementspotential confusing. Our compensation programs are focused on a simple goal: a fair, reasonable and straightforward compensation program that can be, in some ways, difficult to understand and require significant time and cost to properly administer. In the end, we believerewards our compensation arrangements provide the desired results: fair and reasonable payleadership team for achievements beneficial to Natural Gas Services Group, Inc.the Company and its shareholders.

Advisory Vote on Compensation; Shareholder EngagementCompensation

At our 2015 Annual Meeting, less than 50%Although the Advisory Vote on Executive Compensation is not binding on the Company, the Board of Directors assigns significant weight to the outcome of the votes cast onvote and responds accordingly. In the annual advisory “Say-on-Pay” proposal were cast in supportpast five years, the Board and executive management considered the results of the compensation of our named executive officers. This was significantly lower than the support levels of previous years. The results were disappointing since we believe the vote was the result of the influence ofand recommendations of certain proxy advisory firms, both of which advise institutional investors on voting on annual proxy matters. We believe that their reports contained factual errors and assumptions that resulted in questionable conclusions and recommendations. Our specific objections to their reports were detailed in supplementary proxy materials that were distributed last year. It is important to note that while the proxy advisory firms felt that our general compensation structure was lacking in some areas there was no lack of alignment in their ‘pay for performance’ metric and, in fact, they complimented the compensation committee for their continued rigor in setting financial targets.

Although this was a non-binding advisory vote, the Company’s Board of Directors takes the results of this vote seriously, and during 2015 the Company’s Board of Directors and executive management deliberated extensively over the results of last year's "Say-on-Pay" vote andas it engaged in meaningful review of its corporate governance and executive compensation matters with advisors as well asand other stakeholders. The vast majority of input on our compensation programs and executive pay from these shareholders has been positive.
While the
The Compensation Committee and full Board believesof Directors believe that our executive compensation program and corporate governance policies are strongoptimal for the Company, continue to align company leadership with the best interests of shareholders, and have served us well, itfacilitated and supported executive compensation that has delivered industry-leading results. At the same time, the Compensation Committee also recognizes the changingever-evolving compensation and governance landscape.


















Below is a summary of what we heard and the actions we took in response:response to many of these issues during the last five years:

Compensation and Governance Concerns  Responses to the Concerns
Insufficient Risk Mitigators (i.e., lack of clawback policy and stock ownership guidelines)  
We have adopted both a Clawback Policy covering our executive officers and Stock Ownership Guidelines covering our executive officers and members of our Board of Directors. We do note that our company has never had a financial restatement and that each officer and director presently maintains their stock holdings in excess of the minimum guidelines.



  
One Year VestingLong-term incentives for CEO not directly performance driven and one year vesting of Restricted Stock Grants to Executive Officers
The Compensation Committee approved a new frameworkA portion of the long-term incentives for our long-term equity compensation. With respectCEO is now objectively calculated based on total shareholder return compared to our recent restricted stockpeer group, and all long-term incentive awards to our executive officers for fiscal 2015 (granted in early 2016), such awards vest over two years and future awards will vest in one-third increments over three years. Our Compensation Committee continually reviews reports and data relating to the manner in which share awards are determined and vest in keeping with the evolving trends for this type of compensation.
Equity Award for CEO based on one-year TSR
Starting in 2017, the TSR (total shareholder return) performance-driven portion of our CEO’s equity award was based on our three-year TSR results compared to the companies in our peer group.


  
Excessive Cash Severance  
We do not feel that the cash severance benefits for our Chief Executive Officer are excessive. Any change of control severance requires a ‘double-trigger’ to be payable and the triggers are limited to the standard "good reason" "Good Reason" events (see page 43)47). We believe the severance benefits are within the norms of companies in our industry that exhibit a similar performance profile that we do, i.e., industry leading total shareholder returns in each ofover the past one,last three and five year periods. Please see the chartstabular disclosure on page 2326 and the 20152020 performance achievements below. The cash severance due to our CEO in connection with "good reason" events (typically be an involuntary occurrence) equates to approximately three years of total compensation based upon a year of good performance, which the Company has consistently demonstrated.


  
Lack of Lead Independent Director  
We have had an appointed lead director for years, but have amended our Corporate Governance Guidelines to include the public identification and acknowledgment of a lead independent director. Charles G. Curtis, our longest tenured independent director, has been formallyDirector. John W. Chisholm was appointed as our lead director.
Targeting 75th percentile for CEO's total compensationLead Director in June 2020.
Our CEO's total compensation (base pay and short and long term incentives) has been between the 50th and 75th percentile when compared to peer group companies with the final approved compensation being a combination of the CEO's and the Company's performance. Typically, although it can vary, base salary of our CEO has been in the 50th percentile range while long term incentives are employed to increase the compensation package to competitive levels. This allows the Compensation Committee to annually adjust the CEO's long term incentives in keeping with shareholder returns and Company performance. We think this is an appropriate alignment of pay relative to performance of the company and the competitive market. Supporting this practice is the fact that the Company has performed in the top 15% to 25% of peer group companies for Total Shareholder Return in the last one, three and five year periods (please see pages 22 and 23 for relevant data). Our Compensation Committee believes this performance has justified total compensation being awarded in the 75th percentile range in recent years. However, in the future, if the relative performance of the Company lags our peer group of companies, then the CEO’s total compensation will be evaluated under those circumstances.
Awarding long-term equity awards on a purely discretionary basis with minimum awards guaranteedIn the future, long-term equity awards will be based on a combination of the relative TSR (Total Shareholder Return) of the Company when compared to our peer group of companies and a discretionary component that shall be evaluated by the Compensation Committee.

The Compensation Committee, with the assistance of the compensation consultant,Compensation Consultant, reviewed the companies comprising the Custom Peer Group in order to maintain its appropriateness for the competitive pay analysis. These companies were generally selected since they are all companiesas peers in the energy and energyoilfield services industry of similar size based on market capitalization and have various rental, leasing or manufacturing components in their business with all having an acceptable range of relatively similar annual revenues and market capitalization.other competitive variables. The Compensation Committee believes market capitalization should be the Customprimary metric used when selecting industry peers for executive compensation purposes. The Compensation Committee believes the Peer Group reflects our current competitors for employee talent and that it provides an appropriate comparison of peer setcompanies for the purposes of evaluating our pay practices and the Chief Executive Officer’s pay levels.

The Compensation Committee used the competitive pay information and surveys as a “market check” to ensure, in its subjective judgment, that the Chief Executive Officer’s base salary, target total cash compensation, long-term incentive awards and total direct compensation remain competitive. The Compensation Committee does not target any individual pay component to fall within a specific range or percentile of the competitive pay information. While the competitive pay information is important to the Compensation Committee’s approval process, it is just one of several factors considered by the Compensation Committee in approving executive compensation and the Compensation Committee has discretion in determining the nature and extent of its use.

Individual and Company Performance - Base Salary and Equity Awards

The Compensation Committee also evaluates compensation, particularly base salary levels and equity awards (restricted stock awards), through an analysis of each executive officer’s individual performance and the overall performance of Natural Gas Services Group,the Company, our goal being to strengthen the link between what we pay our executives and the performance of Natural Gas Services Group.the Company.  Factors the Compensation Committee considers in our analysis include:

theThe individual performance, leadership, business knowledge and level of responsibility of our officers;
theThe particular skill-set and longevity of service of the officer;
theThe effectiveness of the officer in implementing our overall strategy; and
theThe general financial performance and health of the Company.

The upholding and implementation of key Environmental, Social and Governance principles established by the Board of Directors and its committees.
Our CEO is additionally evaluated on his specific ability and effectiveness with respect to shareholder and customer engagement.


Specific Company Financial Metrics - Cash Bonuses

With respect to compensation we pay in the form of cash bonuses, the Committee sets performance levels for three specific companyCompany financial metrics.  The Committee relies on whether these levels are achieved and the individual performance of our executive officers to determine whether cash bonuses are awarded and the amounts of such bonuses.  The three financial metrics the Committee considers are:

totalTotal revenues;
adjustedAdjusted EBITDA; and
adjusted netNet income before taxes.

Adjusted EBITDA is calculated from our audited financial statements by adding to net income or loss, (1) amortization and depreciation expense, (2) interest expense, (3) provision for (or benefit from) income tax expensetaxes, (4) impairment of goodwill, (5) an increase in inventory allowance, and (4)(6) loss on retirement of rental equipment.

We believe that our core executive compensation mix of base salary, cash bonuses, and equity awards while fairly limited,and other long-term incentives presently provides enough diversity for us to link executive compensation to our short-term and long-term objectives.  For instance, base salary and cash bonuses generally relate to short-term achievements and objectives while equity awards are more closely linked to the long-term objectives of earnings per share and increased market value of our common stock or maintenance of market value in periods of depressed industry performance, such as during the past two years.


Base Salary

We provide our executive officers and other employees with base salary to compensate them for services rendered during the fiscal year.  Each year the Compensation Committee receives base salary recommendations from our Chief Executive Officer for all of our executive officers (other than our Chief Executive Officer whose base salary is evaluated by the Compensation Committee on an annual basis).

In January 2015,April 2020, the Compensation Committee reviewed the 20142019 performance of our Chief Executive Officer, Stephen C. Taylor, along with the competitive pay information provided in Longnecker’sthe Compensation Consultant’s report, in setting Mr. Taylor's base salary for 2015. Before the increase in salary for 2014, Mr. Taylor’s base salary fell to slightly less than the 50th percentile bracket in the Company’s peer group. In connection with2020. Based on that review and considering economic, industry and public health challenges at that time, the Compensation Committee increasedmaintained the base salary of Mr. Taylor from $505,175 in 2014 to $543,063 in 2015, which moved Mr. Taylor’s base salary to approximately the 63rd percentile bracket. The increase was made in recognition of Mr. Taylor’s leadership and contributions to the Company's strong 2014 financial and operational results, which included: (i) increasing total gross margin, exclusive of depreciation and amortization, by 11.4% to $53.8 million for 2014 from $48.3 million for 2013; (ii) achieving in 2014 record high revenue of $97 million, a 9.0% increase in revenue from 2013; (iii) a 7% increase in EBITDA; generating $34.6 million from operations, while investing $53.1 million in capital for equipment; (iv) controlling SG&A expense to 10.6% of revenues; increasing rental revenue by 14.4%; internally funding over $175 million in growth capital since 2010 while maintaining a very low debt level when compared to competitors; (v) maintaining high margins and maintaining high ratios of operating income, net income and EBITDA when compared to gross revenues relative to competitors; (vi) aggressive expansion into new geographic areas; (vii) positioning our business to emphasize servicing oil and gas production


at $612,000.
rather than drilling projects in order to offset drilling slowdowns as witnessed in the latter half of 2014; and (viii) maintaining safety performance.

While the Compensation Committee reviewed the competitive pay information in connection with setting Mr. Taylor's base salary adjustments, together with his contributions toward our goals, the Compensation Committee did not target his base salary to fall within a specific range or percentile of the competitive pay information.26




With respect to our other two named executive officers other than our CEO, the base salary in 2020 of James Hazlett, our Vice President ofPresident- Technical Services, base salary for 2015 was $200,000 compared to $190,000 for 2014.remained unchanged from 2019 at $225,100. The base salary of G. LarryJames R. Lawrence, our Vice President and Chief Financial Officer at the time who joined the Company in October 2019, was increased from $200,000 to $210,000. Mr. Lawrence resigned in December 2020.

Annual salary reviews for 2015, was $187,000 compared to $170,000 for mostMr. Taylor and Mr. Hazlett were conducted in March 2021 and, in light of 2014. We continue, as we have in the past, to rely on the following factors in evaluating and determining the amount of compensation we pay these executives:

our general knowledge of executive compensation levels in the natural gas compressioncontinuing economic, industry and similarly sized energy service companies;
each executive’s individual performance andpublic health challenges, the overall performance of Natural Gas Services Group; and
specific company financial metrics andCompensation Committee elected again to not increase the application of specific weights to such metrics.

The applicabilitybase salaries of these factors varies depending on the type of compensation being evaluated and determined.  For instance, we do not rely on weighted company financial metrics to evaluate and determine base salary levels (which are competitively set to the market), but the achievement of pre-set financial metrics are the primary means through which we evaluate and determine the amount of the cash bonuses we award to our executives. Below is a more detailed discussion of how these factors apply to the different types of compensation we utilize.officers for 2021.

Short-Term Incentives - Annual Incentive Bonus Plan

In 2006, the Committee adopted an Annual Incentive Bonus Plan or, the “IBP,” that provides guidelines for the calculation of annual non-equity incentive based compensation in the form of cash bonuses to our executives, subject to Committee oversight and modification.  The bonuses awarded under the IBP are short-term awards in recognition of the overall performance and efforts made by certain of our executives during a particular year. Each year, the Committee approves the group of executives eligible to participate in the IBP and establishes target award opportunities for such executives. For 2015,2020, the Committee maintained Mr. Taylor’s target award opportunity to up toat 100% of his base salary. Target award opportunity was 50% of average base salary for Messrs. Lawrence andMr. Hazlett.

In 2015,For 2020, 90% of an executive officer’s IBP award was based on achievement of company financial objectives relating to:

totalTotal revenues;
adjustedAdjusted EBITDA; and
adjusted netNet income before taxes.

Each of these three components accounts for 30% of the total company financial objective portion of the IBP. The remaining 10% of an executive officer’s IBP award is based upon individual performance as evaluated by our CEO (except with respect to our CEO whose individual performance is evaluated by the Committee).

Each year, the Committee sets athree performance levellevels for each component of the company financial objective portion of the IBP.  The payment of awards under the IBP is based upon whether these performance levels are achieved for the year.  Payout on each of the three financial objectives is as follows:

75% of the bonus amount attributable to a financial component will be paid if we achieve at the "threshold" amount;

100% of the bonus amount attributable to a financial component will be paid if we achieve the "target" amount; and

125% of the bonus amount attributable to a financial component will be paid if we achieve the "stretch" amount.

Based upon this review, the Compensation Committee determined it was appropriate to adjust the long-term incentive award in 2018 to provide a balance between a quantitative, performance-based award and a qualitative, discretionary award based on performance measures evaluated annually by the Compensation Committee and Board of Directors, a practice consistent with the Company’s peers and, more generally, other oilfield services companies.

The performance-based award was based off the Company’s relative prior three-year total shareholder return (“TSR”) compared to the company-defined peer group. The Compensation Committee established the following award parameters based on the company’s relative TSR performance.

The award is determined by the Company’s ranking on the peer-based table below:

The qualitative, discretionary award was set to a maximum of 200% of the base pay of the named executive officer and will vest in equal parts over a three-year period. Performance measures taken into account include those provided in the 2020 Financial and Operational Highlights section of this Proxy as well as other personal achievements of the respective executive officers. Other factors considered include demonstrated company leadership, financial stewardship, market effectiveness, and strategic vision, insight and execution.

The Compensation Committee considers restricted stock and restricted stock units to be a type of long-term incentive compensation that motivates our executive officers to work toward our long-term growth and allows them to participate in the growth and profitability of Natural Gas Services Group.the Company. We believe that restricted stock aligns the interests of our executive officers with our shareholders in that our executive officers will benefit from the restricted stock only to the extent that the value of our common stock increases. With the exception of Mr. Taylor, our Chief Executive Officer, the number of shares of restricted stock granted to an executive officer is based on a subjectivediscretionary determination of an officer’s individual performance and his current contributions and potential for future contributions to the overall performance of the Company.

In early 2021, the Compensation Committee reviewed the Company’s 2020 TSR performance against its peers and determined that the Company’s prior three-year performance was sixth out of the Company identified 14-member peer group (including Natural Gas Services Group. InGroup). Such performance, as noted in the accompanying table, entitled Mr. Taylor to a TSR performance-based award of 118% of his current base salary of $612,000.

With respect to Mr. Taylor’s employment agreement we havepersonal performance, the Committee considered his continued leadership in guiding the Company through past and current market downturns related to collapses in oil and natural gas prices by maintaining a strong balance sheet through reductions in operating and capital expenses. Mr. Taylor’s leadership positioned the Company with a balance sheet that enabled it to significantly increase capital spending, without incremental debt, to meet the opportunity to establish a meaningful presence in the high horsepower compression market. Mr. Taylor developed significant contractual commitments from customers for the Company’s high horsepower equipment, allowing it to grow its market share in a key new market.

After a review of all relevant Company and personal performance factors, the Committee agreed to awardprovide Mr. Taylor a restricted stockan additional discretionary award or equivalent equity awards in January of each year with an aggregate minimum value equal to at least 175%200% (of a 200% maximum opportunity) of his Base Salary, subjectcurrent base salary of $612,000.

On a preliminary basis, Mr. Taylor's performance-based and discretionary long-term incentive awards totaled $1,946,160. Due to the current vesting termsdifficult economic and other standard terms which shall be established byindustry conditions and the resulting impact on the Company's share price, the Compensation Committee taking into account the performancestructured Mr. Taylor's long-term incentive award as follows:

A long-term incentive award of $973,080 (50% of the Company, Mr. Taylortotal earned award) that vests in equal, annual tranches over three years, with the amounts being payable in cash or common stock at the time of vesting at the discretion of the Compensation Committee; and industry norms. Our compensation consultant concurred with our approach relating to
A long-term incentives and recommended that we continueincentive award of 109,212 shares of restricted stock, which represents the practice.balance of the total earned award. This was calculated by dividing $973,080 by a deemed share price of $8.91, which was the market closing price on March 18, 2021.

In 2009,addition, upon Mr. Taylor's recommendation, the Committee approved a discretionary grant of 20,000 shares of restricted stock to Mr. Hazlett.

All restricted stock grants were awarded under the Company's 2019 Equity Incentive Plan using the closing price of $8.91 per share as of March 18, 2021, with the totals noted in the table below:

Stephen C. Taylor, CEO and President$973,079  109,212  
James R. Hazlett, Vice President - Technical Services$178,200  20,000  

All of the restricted stock awards reported above are subject to a three-year vesting period, although such vesting is subject to acceleration and will immediately vest upon certain events, such as (i) death or disability of the recipient employee or (ii) certain circumstances in connection with a change of control in the Company. Further information concerning these awards is set forth in column (e) of the "Summary Compensation Table" on page 34 and column (i) of the "Grants of Plan-Based Awards for 2020" on page 36.

The Compensation Committee continuously evaluates the Company’s executive compensation plan to ensure that the each of the components of that plan is designed, when considered both individually and holistically, with the goal of attracting and retaining executive leadership capable of delivering industry leading results for shareholders. This review, with the assistance of Board-retained executive compensation experts, includes reviewing peer-group compensation programs, broader industry compensation trends, innovations in executive compensation design as well as seeking input from our shareholders and other stakeholders.

The Compensation Committee notes that there has been significant evolution in executive compensation plan design in the past several years including changes in standard performance measures and measurement periods. The Compensation Committee will continue to consider changes to industry executive compensation practices as it contemplates future changes to the Company’s executive compensation program.

In addition, in 2019, we adopted the 2009 Restricted Stock/Unit2019 Equity Incentive Plan (the “Plan”("the Plan") and itwhich went into effect upon its approval by our shareholders at our 20092019 annual meeting. We typicallyThe Compensation Committee does not have any specific program or plan with regard to the timing or dating of restricted stock or units grants. However, the Committee's practice will likely be to grant awards underafter Natural Gas Services Group's annual earnings releases. We have not and do not plan to purposefully time the Plan to our executive officers and Directors duringrelease of material non-public information for the first quarterpurpose of each year after reviewing the Company's operational and financial results from the previous year.

During the first and second quarters of 2016, the Company granted the following restricted stock awards in connection with our 2015 financial and operational results and personal accomplishments of our named executive officers:

Pursuant to Mr. Taylor's employment agreement, we are required to grant a restricted stock award or equivalent equity awards in January of each year with an aggregate minimum value equal to at least 175% of his Base Salary. See “Compensation Agreements with Management” beginning on page 41 of this Proxy Statement for information concerning Mr. Taylor’s employment agreement.

The Committee also reviewed Mr. Taylor's total compensation level along with Company's performance and Mr. Taylor's personal performance in connection with determiningaffecting the value of the 2015 restricted stock award. As a result of the Committee's review, the Committee awarded Mr. Taylor (i) 44,284 shares of restricted common stock pursuant to the terms of his employment agreement and (ii) an additional 31,631 shares of restricted common stock in recognition of our 2015 financial and operational results and performance, for a total award of 75,915 shares of restricted common stock. The restricted shares are subject to a two year vesting period (half of the shares vest on the first anniversary date and the remaining half on the second anniversary date), although such vesting is subject to acceleration and will immediately vest in the case of (i) death, disability or retirement of the recipient employee, or (ii) a change of control in the Company, as set forth in the Plan.executive compensation.

On April 6, 2016, the Compensation Committee awarded 20,000 shares of restricted common stock to each of G. Larry Lawrence, our Chief Financial Officer and James R. Hazlett, our Vice President-Technical Services. The restricted shares are subject to a two year vesting period (half of the shares vest on the first anniversary date and the remaining half on the second anniversary date). All of the restricted shares are subject to acceleration and will immediately vest in the case of (i) death, disability or retirement of the recipient employee, or (ii) a change of control in the Company, as set forth in the Plan.

The additional restricted shares which were issued to Mr. Taylor in excess of the 175% of his Base Salary obligation under the terms of his employment agreement, and the restricted stock awards to our other two named executive officers were made in recognition of their personal performance and of the Company's 2015 financial and operational performance as set forth under "Fiscal Year 2015 Performance" on page 20 of this Proxy Statement.

Further information concerning these awards is set forth in column (i) of the "Summary Compensation Table" on page 32 and column (i) of the "Grants of Plan-Based Awards for Fiscal 2015" on page 34.


Other Compensation

We maintain a 401(k) retirement plan in which all of our executives and employees are eligible to participate.  We match executive and employee contributions to our 401(k) plan, on an equal percentage basis, with cash contributions.  The Company matching portion is equal to one-half of the employee’s annual contribution up to a maximum of 3% of the employee’s salary. Our matching amounts for our executive officers are included in column (i) of the “Summary Compensation Table” on page 32.


Total Direct Compensation

In determiningAmong its peer group companies, the extent to which our chief executive officer compensation program meets the Committee’s compensation philosophy and objectives, the Committee considers the competitiveness of total compensation (the aggregate of base salary, annual cash bonus incentive payment, and the grant value of long-term incentive plan award). Using the Custom Peer Group data from Longnecker’s study and discussing with Longnecker the pay practices of our peers, the total compensation for Mr. Taylor, our Chief Executive Officer, was at approximately the 75th percentile bracket which the Committee believed to be warranted considering our relatively strong (i) 2015 financial and operational results during a difficult time for companies in the oil and gas industry and (ii) total shareholder return when comparedfrom NGS was in the 69th percentile in 2020, 62nd percentile over the past three years and the 67th percentile over the past five years.

Due to the significant economic and industry dislocations resulting primarily from the public health challenges presented by the COVID-19 pandemic and significantly lower energy commodity prices, a number of our former peer group

companies have either filed for bankruptcy protection or ceased operations, requiring changes to our peer group.group and related CEO compensation comparisons. Due to such changes data comparing the Company’s Chief Executive Officer’s pay to the peer group may be less reliable as a relative measure than in previous years.


Employment Agreements

We employed Stephen C. Taylor, our President and Chief Executive Officer, joined the Company in January 2005. On October 23, 2013, we entered into a new written employment agreement with Mr. Taylor. We do not have written employment agreements with any of our other executive officers. On April 24, 2015, we entered into an amendment with Mr. Taylor to his Employment Agreement pursuant to which the "modified single trigger" change of control provision was changed to a "double trigger" change of control. Under the "modified single trigger provision", Mr. Taylor could voluntarily terminate the Employment Agreement for any reason immediately upon a change in control and collect severance benefits. Under the new "double trigger" change of control provision, a change of control must occur followed by the Company or its successor terminating Mr. Taylor's employment other than for cause, death, or disability, or by Mr. Taylor terminating his employment for Good Reason. See “Compensation Agreements with


Management” beginning on page 4147 of this Proxy Statement for detailed information concerning Mr. Taylor’s employment agreement, as amended.

Allocation of Amounts and Types of Compensation

Other than the restricted stock awards we grant to our executives from time to time and the determinations made by the Committee as to specific target award opportunities under our IBP, the allocation of different amounts and types of compensation has not been a consideration for us, except with respect to our Chief Executive Officer whose employment agreement currently requires an annual restricted stock award or similar equity award with a value of at least 175% of his base salary.  However, the Committee is in the process of revising its long-term equity compensation program to a hybrid performance and discretionary methodology. See "Chief Executive Officer Equity Compensation" on page 39.  The Committee has not adopted a specific policy or target for the allocation between amounts or types of compensation. We believe thatThe Committee considers data from the use of stockpeer group companies in reviewing compensation allocations and practices and strives to create a balance between short- and long-term compensation through (i) reasonable base salary amounts, (ii) the IBP cash bonus program for achieving short-term financial and operational metrics, along with personal performance achievements and (iii) long-term incentive through equity awards in our compensation package will align the interests of our management and employees with our stockholders.  Notwithstanding moderately increasing the use of stock-based compensation, we intend to maintain and continue our practice of having a simplified, but effective and competitive, compensation package.


Change of Control and Severance Arrangements

Our 1998 Stock Option Plan, as amended, and our 2009 Restricted Stock/Unit Plan contains change of control provisions.  In addition, Mr. Taylor’s employment agreement contains change of control and severance provisions.  Information regarding these provisions is provided under the caption “Potential Payments Upon Termination or ChangeCompany's equity incentive plan. The Committee believes its allocation methodology does not over-emphasize short-term performance at the expense of Control” on page 38.achieving long-term goals.


Perquisites

We provide limited perquisites to our executives. The primary perquisites include allowingallow our executives a choice of receiving an automobile allowance or personal use of a company-provided automobile and matching contributions made by Natural Gas Services Group under our 401(k) plan.automobile.  Although we provide Mr. Taylor with one clubMidland Petroleum Club membership, since his use of the club is limited solely for business entertainment, we have not considered it to be a perquisite and have not valued it as such for inclusion in column (i) of the "Summary Compensation Table" on page 32.34.

Our executives also participate in the same medical, dental and life insurance plans as other employees.  However, we pay a greater percentage of the premiums for health insurance for our executives than we do for our other employees.
    

Limit on Deductibility of Certain Compensation

Provisions of the Internal Revenue Code that restrict the deductibility of certain compensation over $1 million dollars per year have not been a factor in our considerations or recommendations. Section 162(m) of the Code currently imposes a $1 million limitation on the deductibility of certain compensation paid to specified executives. Excluded from the limitation is compensation that is “performance based.” For compensation to be performance based, it must meet certain criteria, including being based on predetermined objective standards approved by shareholders. The Committee has not taken the requirements of Section 162(m) into account in designing executive compensation.

Say-on-Pay

At our 20152020 Annual Meeting of shareholdersShareholders held in June 2015,August 2020, we submitted a proposal to our stockholdersshareholders regarding our executive compensation practices. The proposal was an advisory vote on the 20142019 compensation awarded to our named executive officers (commonly known as a “Say-on-Pay”“say-on-pay” vote). Excluding broker non-votes, ourOur shareholders disapproved our 20142019 compensation with less than half (48.6%)approximately 49.6% of the shares that votedvotes cast on the proposal voting in favor of our 20142019 executive compensation practices.

As noted at the beginning

Our management, Compensation Committee and Board of this section, the results were disappointing since we believe the vote was the result of the influence from recommendations fromDirectors (along with our Compensation Consultants) have carefully reviewed our executive compensation plan as well as input provided by stakeholders, including our shareholders and proxy advisory firms, of which advise institutional investors on voting on annual proxy matters. We believe that their reports contained factual errors and assumptions that resultedservices. While we have been limited in questionable conclusions and recommendations, and in June 2015 we sent a letterface-to-face dialogue with key stakeholders due to the proxy advisory firms which detailed our issuesCOVID-19 pandemic, we have had comprehensive dialogue with their reports. We


also sent our shareholders a copy of these letters and filedother stakeholders regarding our correspondence with the Securitiesexecutive compensation program. In recent years, we initiated several new compensation and Exchange Commission on June 15, 2015. You can access this filing free of charge on the Investor Relations section ofgovernance measures that address concerns raised by our website (stakeholders, including:
www.ngsgi.com). A paper copy is also available, without charge upon written request, at Natural Gas Services Group, Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701. 


Notwithstanding, we took numerous remedial measures, including:

adopting a clawback policy thethat covers all executive officers;
adopting executive and directorDirector stock ownership guidelines;
extending the vesting terms on restricted stock awards made to our executive officers;officers to three years;
calculating a portion of our CEO’s long-term equity award to meeting set objective total shareholder returns compared to our Custom Peer Group;
adopting a majority votes cast requirement with respect to the election of Directors; and
amending our Corporate Governance Guidelines to include a leadan independent director.Lead Director. Charles G. Curtis was appointed Lead Director in April 2016 and served in that capacity until his retirement from the Board in June 2020. John W. Chisholm was appointed Lead Director in June 2020.
NGS is committed to aligning our longest tenured independent director, has been appointed as our lead director; and
amending our Bylaws to require a majority vote standard in connectionexecutive compensation practices with the uncontested electionbest interests of our stakeholders. The Company, in previous years, has attempted to engage proxy advisory services in discussions to better understand and respond to their concerns and critiques of our compensation structure. While we have been confounded by the reticence of proxy advisory firms to engage in dialogue, we have worked diligently with our shareholders (please see "Shareholder Engagement" on page 15) to ensure our executive compensation structure meets our shareholders’ expectations and is designed to elicit optimal performance from our executives.

As a result of the COVID-19 pandemic and its impact on our business, the Board of Directors subjectand the Compensation Committee determined that the actions of our executive management team resulted in the Company protecting the health and safety of our employees while maintaining continuous commercial operations that resulted in improved cash balances, reduced but profitable field operations and flexible business model that provided for relative employee stability and safety without sacrificing the ability to shareholder approval.meet customer needs. While 2020 compensation may not directly reflect the performance of our equity, the preservation our enterprise without compromising employee safety or customer responsiveness are, in the Board’s opinion, attributes that deserve appropriate recognition and compensation.

Corporate Governance Policies

To ensure our compensation programs are aligned with the long-term interest of our shareholders, we have adopted several governance policies that we expect our executive officers to comply with, including meaningful stock ownership guidelines, a pledging and hedging policy and a recapture or “clawback” policy that provides for the recoupment of any performance-based payouts made based on financial results that are not in compliance with any financial reporting requirement that requires restatement of the Company’s financial statements. In addition, to provide our shareholders with a meaningful role in the election of Directors and to enhance our corporate governance standards, we have adopted a "majority vote" requirement in the election of Directors, subject to the approval of our Shareholders at the annual meeting (see Proposal 5). Below are summaries of these new policies.

Compensation Clawback Policy

The Company has adopted a compensation recoupment, or “clawback” policy intended to be consistent with the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). This policy provides that, in the event we are required to restate our financial statements as a result of “material noncompliance” with financial reporting requirements under the securities laws, we will recover from our current and former executive officers any incentive-based compensation (including equity awards) that is (i) based on material erroneous data, (ii) received during the three-year period preceding the date on which the Company becomes required to prepare an accounting restatement, and (iii) in excess of what would have been paid if calculated under the restatement. In addition, the Dodd-Frank Act requires the SEC to issue regulations requiring issuers to seek recovery from executive officers in certain circumstances involving financial restatements. The SEC has issued proposed regulations implementing this portion of the Dodd-Frank Act. Once the SEC finalizes its regulations regarding the required form of a clawback policy under the Dodd-Frank Act, we expectintend to amend our clawback policy accordingly.if necessary to comply with the SEC rules and NYSE implementation of those rules.




32




Pledging and Hedging Policy

The Company considers it improper and inappropriate for any director,Director, executive officer or associate to engage in short-term or speculative transactions involving our Common Stock. We therefore prohibit directors,Directors, executive officers and other associates from engaging in pledging, short sales or other short position transactions in our Common Stock. We also strongly discourage directors,our independent Directors, executive officers and other associatesemployees from engaging in certain forms of hedging or similar monetization transactions. Any deviation from the policy must be approved in advance by our CEO and Board. To our knowledge, all such individuals are in compliance with this policy.













Director and Executive Officer Stock Ownership Guidelines

The Company has stock ownership requirements for its directorsDirectors and executive officers. The purpose of the ownership requirements is to further our goal of increasing shareholder value and to further alignaligning the interests of our directorsDirectors and key executives with the interests of our shareholders. Satisfaction of the policy requires that individuals attain and retain holdings of our common stock with a market value equal to the following multiple of the individual’s compensation, defined as either a director’sDirector’s cash retainer fee or an officer’s base salary. Shares included in the minimum share ownership calculation include: shares owned outright or beneficially owned; vested restricted stock; vested restricted stock units in our Deferred Compensation Plan; and shares issued from the exercise of vested options.

The table below indicates the stock ownership guidelines for our executive officers and Board members:

Stock Ownership Guidelines

Executive Officer/Director (as a multiple of base salary/annual cash retainer)
CEO3 times Base Salary
All other executive officers2 times Base Salary
Non-employee Directors1 times Base Annual Cash Retainer


Each person’s stock ownership requirement will be adjusted annually each January 1 to reflect any changes in his or her retainer or base salary. Generally, individuals have a five-year period to attain their stock ownership requirements. At any time at which the individual’s stock ownership requirement has not been met, including during the initial five-year period to attain compliance, the individual will be required to retain at least 50% of “Net Shares” received upon vesting of restricted stock, restricted stock units and performance units. “Net Shares” are defined to include shares of common stock that are owned by the individual after shares are sold, swapped or traded to pay applicable withholding taxes. Subsequent to achieving the initial stock ownership requirement, all directorsDirectors and executives are required to continuously maintain stock ownership at their specified levels.

If an individual does not meet the applicable ownership requirements, then he or she is subject to certain restrictions upon the vesting of equity awards, and may only dispose of shares for particular reasons set forth in the policy. The policy provides a hardship exemption, for which an individual must submit a request to the corporate governance committee.Environmental, Social and Governance and Personnel Development Committee. Presently, all of our directorsDirectors and our executive officers have attained or exceeded their ownership requirements.

Majority Vote Standard in Uncontested Director Elections
In April 2016, the Board amended our Bylaws to implement a majority vote standard in uncontested elections of Directors. Prior to this amendment, Directors were elected by plurality vote, meaning that nominees for the election of Directors who received the greatest number of votes cast in favor of his or her election would be elected to the Board even if such number of favorable votes was less than a majority of votes cast in the election. Under our revised Bylaws, in uncontested elections each Director must be elected by an affirmative majority of the votes cast. Under our new Bylaw provisions in connection with uncontested elections, abstentions and broker non-votes will not be counted and will have no effect in determining whether the required majority vote has been obtained. With respect to contested elections (those where the number of nominees exceeds the number of directors to be elected), a plurality vote standard will continue to apply. This amendment to our Bylaws requires Shareholder approval at the annual meeting (see Proposal 5).

The Compensation Committee will continue to consider the outcome of Say-on-Pay votes when making future compensation decisions for our named executive officers.


Compensation Committee Report

The Committee has reviewed and discussed the Compensation Discussion and Analysis with management. Based on its review and discussions, the Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in our proxy statement for the 2016 Annual Meeting of Shareholders.

Annual Incentive Bonus Plan

Our Annual Incentive Bonus Plan, or,that each executive officer receives his full personal performance portion (10%) of the “IBP,” provides for annual non-equity incentive based compensation in the form of cash bonuses to our executive officers.  Our Compensation Committee administersbonus and determines from year to year the executives that are eligible to participate in the IBP.  The Committee establishes target award opportunities for the executives eligible to participate in the plan.  These target award opportunities are expressed as a percentage of an executive’s base salary.  An executive’s target award opportunity is the maximum cash bonus an executive is eligible to receive in any one year under the IBP.

The Committee establishes annual performance levels for Natural Gas Services Group’s total revenues, adjusted EBITDA and adjusted net income before taxes and assigns a weight of 30% to each of these components.  The executive’s individual performance is assigned a weight of 10%.  Detailed information regarding the IBP30% metrics are achieved under threshold (75% payout), target (100% payout), and the calculation of awards is providedmaximum / stretch (125% payout) levels. As discussed in further detail on page 27 under the caption “Short-Term Incentives - Annual Incentive Bonus Plan” on page 25.Plan,” the actual payouts in April 2021 that were earned in 2020 were as follows: Mr. Taylor - $612,000 and Mr. Hazlett - $112,550.

The Board may amend the 2019 Plan. However, except in the case of adjustments upon changes in common stock, no amendment will be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary to satisfy any applicable laws.

Eligibility.  The Board selects participants from among the key employees, consultants and Directors of the Company and its affiliates. Only employees are eligible to receive incentive stock options.

Available Awards. Awards that may be granted under the 2019 Plan include restricted stock, restricted stock units (RSUs), performance awards, stock options (including both incentive stock options (ISOs) and nonqualified stock options), stock appreciation rights (SARs), and other stock-based awards. The terms of each award will be set forth in a written agreement.

Restricted Stock. A restricted stock award is an award of actual shares of common stock which are subject to certain restrictions for a period of time determined by the Committee. Restricted stock may be held by the Company in escrow or delivered to the participant pending the release of the restrictions. The participant generally has the rights and privileges of a shareholder as to such restricted stock during the restricted period, including the restrictions applicableright to shares underlying awards ofvote the restricted stock and the dates theseright to receive dividends

Restricted Stock Units. An RSU is an award of hypothetical common stock units having a value equal to the fair market value of an identical number of shares of common stock, which are subject to certain restrictions lapsefor a period of time determined by the Committee. No shares of common stock are issued at the time an RSU is granted, and the Company is not required to set aside any funds for the payment of any RSU award. Prior to settlement of an RSU award vests,and the receipt of shares, the participant does not have any rights as well asa shareholder with respect to such shares. The Committee may grant RSUs with a deferral feature (deferred stock units or DSUs), whereby settlement of the RSU is deferred beyond the vesting and settlement terms applicabledate until a future payment date or event set out in the participant’s award agreement. The Committee has the discretion to RSUs. Whencredit RSUs or DSUs with dividend equivalents.

Performance Share Awards. A performance share award is an award vests, we deliverof shares of common stock that are only earned if certain conditions are met. The Committee has the discretion to determine the participant a certificate forfollowing: the number of shares withoutof common stock or stock-denominated units subject to a performance share award; the applicable performance period; the conditions that must be satisfied for a participant to earn an award; and the other terms, conditions and restrictions of the award. The number of performance shares earned by a participant depends on the extent to which the performance goals established by the Committee are attained within the applicable performance period. No payout is made with respect to any legendperformance share award except upon written certification by the Committee that the minimum threshold performance goal(s) have been achieved.

Stock Options. A stock option is the right to purchase shares of common stock at a future date at a specified price per share called the exercise price. An option may be either an ISO or restrictions (except as necessarya nonqualified stock option. ISOs and nonqualified stock options are taxed differently. Except in the case of options granted pursuant to complyan assumption or substitution for another option, the exercise price of a stock option may not be less than the fair market value (or in the case of an ISO granted to a ten percent shareholder, 110% of the fair market value) of a share of common stock on the grant date. As of the record date, the closing price of our common stock was $9.05. Full payment of the exercise price must be made at the time of such exercise either in cash or bank check or in another manner approved by the Committee.

Stock Appreciation Rights. A SAR is the right to receive payment of an amount equal to the excess of the fair market value of a share of common stock on the date of exercise of the SAR over the exercise price. The exercise price of a SAR may not be less than the fair market value of a share of common stock on the grant date. SARs may be granted alone ("freestanding rights”) or in tandem with applicable state and federal securities laws)options ("related rights”).

In additionOther Equity-Based Awards. The Committee may grant other equity-based awards, either alone or in tandem with other awards, in amounts and subject to conditions as determined by the Committee as set out in an award agreement.

Vesting. The 2019 Plan allows for awards subject to either time-based vesting or performance-based vesting, or both. All awards granted under the 2019 Plan must have a minimum vesting period of at least one year. The Committee has the authority to determine the vesting schedule of each award (subject to the minimum one-year requirement), and to accelerate the vesting and ability to exercise any award. The Company’s practice over the last several years has been to grant restricted stock/unit awards to its executive officers and independent Directors, and stock options to selected non-executive employees. Restricted stock/unit awards to our (i) executive officers have been subject to time-based vesting requirements,in equal one-third installments over a three-year period from the Committee is also authorizedgrant date and (ii) independent Directors have been subject to establish quantitative and qualitative performance goalstime-based vesting in order forequal quarterly installments beginning in the year following the year in which they are granted. Starting in 2020, the awards to vest.  For instance, quantitative performance standards, including, but not limited

independent Directors are subject to financial measurements such as (a) increaseone-year cliff vesting. Stock options granted to our non-executive employees typically vest in share price, (b) earnings per share, (c) total shareholder return, (d) operating margin, (e) gross margin, (f) return on equity, (g) return on assets, (h) net operating income, (i) pre-tax profit, (j) cash flow, (k) revenue, (l) expenses, and (m) EBITDA, or other performance goalequal, one-third tranches over a three-year period.

The Company may cancel any award or require the participant to reimburse any previously paid compensation provided under the 2019 Plan or an award agreement in accordance with the particular restricted stock or RSU agreement which must be met in order for shares to vest.Company’s clawback policy.

Termination of Service.  Unless otherwise set forth in an individual award agreement or in an employment agreement approved by the PlanCommittee, any unvested restricted shares, performance shares, RSUs, PSUs and formsother equity-based awards will immediately be forfeited upon termination of continuous service under the 2019 Plan. Under the Company's restricted stock and RSU award agreements, provide that inif the event a participant’sgrantee's continuous service with us terminates as a result of the grantee's death, disabilityDisability (as defined in the 2019 Plan), termination without Cause (as defined in the 2019 Plan and below) or retirement (an “Acceleration Event”)termination for Good Reason (as defined), 100% of the grantee's unvested shares or RSUs at the time of termination due to an Acceleration Event will immediately become vested, but only to the extent that such unvested shares or RSUs would have vested within the 12 months following the Acceleration Event.  However, the Committee may revise this default provision onvest.

Unless otherwise set forth in an individual basis, as it deems advisable.  For example, the Committee could elect to accelerate vesting for all unvested shares and/award agreement or RSUs upon the occurrence ofin an Acceleration


Event, or conversely provide that all unvested shares and/or RSUs are forfeited upon the occurrence of an Acceleration Event.  In the case of a termination of service other than by an Acceleration Event, any unvested shares of RSUs will immediately become null and void, except that with respect to Restricted Stock awards, the Board of Directors may vest any or all unvested shares in its discretion in the case of any termination of service.

In addition, subject to revision by the Committee, the default provisions of the Plan and form of award agreements provide that a Change of Control triggers accelerated vesting of all shares or units.  Under the 2009 Plan, a Change in Control Event is generally defined as:
a complete liquidation or dissolution;
acquisition of 50% or more of our stock by any individual or entity including by tender offer or a reverse merger;
a merger or consolidation in which we are not the surviving entity; or
during any period not longer than 12 consecutive months, members of the Board who at the beginning of such period cease to constitute at least a majority of the Board, unless the election, or the nomination for election of each new Board member, wasemployment agreement approved by a vote of at least 3/4 of the Board members then still in office who were Board members at the beginning of such period.

Restricted Stock.  Under an award of restricted stock, we issue shares of our common stock in the participant’s name; however, the participant’s rights in the stock are restricted until the shares vest.  If the vesting requirements are not met prior to the end of the vesting period, the shares are forfeited.    In connection with an award of restricted stock, since actual shares are issued and outstanding, the participant is legally entitled to vote the shares and receive any dividends declared and paid on our common stock prior to the satisfaction of the vesting requirements.  However, as discussed above, participants who hold unvested restricted stock may not sell, assign or transfer such shares until they have vested.
Restricted Stock Units.  Like a restricted stock award, a restricted stock unit is a grant valued in terms of our common stock. Unlike a restricted stock award, none of our common stock is issued at the time the RSU award is granted.  Instead, the award is a mere promise to deliver shares of our common stock upon satisfaction of the vesting requirements.  Upon satisfaction of the vesting requirements of the award, we then issue and deliver the number of shares subject to the award.  If the vesting requirements are not satisfied prior to the end of the vesting period, the units expire and no shares are issued.  Since shares of our common stock are not issued in connection with RSUs until such time as the vesting conditions have been satisfied, participants in the Plan who receive awards of RSUs will not have any voting rights and will not be entitled to dividends until such time as the units vest and shares of our common stock are issued.

Amendment, Suspension or Termination of the Plan.  We may at any time amend, suspend or terminate the Plan. The Plan will be for a term of ten (10) years unless sooner terminated. Awards may be granted under the Plan upon it becoming effective, but awards granted prior to obtaining shareholder approval will be rescinded if the shareholders do not approve the Plan.  We may amend the Plan subject to compliance with applicable provisions of federal securities laws, state corporate and securities laws, the Internal Revenue Code, and the rules of the NYSE (or such other stock exchange as our common stock may be traded upon at the time).

Change in Capitalization.  Subject to any required action by our shareholders, the number of shares of common stock covered by outstanding awards, the number of shares of common stock that have been authorized for issuance under the 2009 Plan, the exercise or purchase price of each outstanding award, the maximum number of shares of common stock that may be granted subject to awards to any participant in a calendar year, and the like, shall be proportionally adjusted by the Committee, in the event of: (i) any increasean option holder's continuous service terminates, an option holder may exercise his or decreaseher option (to the extent the option holder was entitled to exercise such option at the date of termination) within the earlier of three months following the date of termination or the expiration of the option term. Unless otherwise set forth in an individual award agreement, in the numberevent an option holder's continuous service terminates upon his or her death or Disability (as defined), an option holder or his or her estate may exercise his or her option (to the extent the option holder was entitled to exercise such option at the date of issued sharestermination), within the earlier of common stock resulting from12 months following the date of termination or the expiration of the option term.

In regards to the definition of Cause under the 2019 Plan, if a stock split, stock dividend, combinationparticipant is under an employment or reclassificationservice agreement with the Company and such agreement provides for a definition of Cause, that definition should be used. If no such agreement exists, or similar event affecting our common stock; (ii)if such agreement does not define Cause, then Cause is defined as (i) the conviction of, or plea of guilty or no contest to, a felony or a crime involving moral turpitude or the commission of any other increaseact involving willful malfeasance or decrease in the number of issued shares of common stock effected without receipt of consideration by us; or (iii) any other transaction with respect to common stock including a corporate merger, consolidation, acquisition of property or stock, separation (including a spin-off or other distribution of stock or property), reorganization, liquidation (whether partial or complete), distribution of cash or other assets to shareholders other than a normal cash dividend, or any similar transaction; provided, however, that conversion of any of our convertible securities shall not be deemed to have been “effected without receipt of consideration.” Except as the Committee determines, no issuance by us of shares of any class, or securities convertible into shares of any class, shall affect, and no adjustment by reason hereof shall be madematerial fiduciary breach with respect to the numberCompany or an Affiliate; (ii) conduct that results in or is reasonably likely to result in harm to the reputation or business of sharesthe Company or any of its Affiliates; (iii) gross negligence or willful misconduct with respect to the Company or an Affiliate; or (iv) material violation of state or federal securities laws.

In regards to the definition of Good Reason under the 2019 Plan, if a participant is under an employment or service agreement with the Company and such agreement provides for a definition of Good Reason, that definition should be used. If no such agreement exists, or if such agreement does not define Good Reason, Good Reason is defined as the occurrence of one or more of the following without the participant’s express written consent, which circumstances are not remedied by the Company within thirty (30) days of its receipt of a written notice from the participant describing the applicable circumstances (which notice must be provided by the participant within ninety (90) days of the participant's knowledge of the applicable circumstances): (i) any material, adverse change in the participant's duties, responsibilities, authority, title, status or reporting structure; (ii) a material reduction in the participant’s base salary or bonus opportunity; or (iii) a geographical relocation of the participant's principal office location by more than fifty (50) miles.

Change in Control. A Change in Control is defined as (a) the acquisition by one person or more than one person acting as a group, of Company stock representing more than 50% of the total fair market value or total voting power of the Company’s stock; (b) a merger, consolidation or other reorganization in which the Company is not the surviving entity unless the Company’s shareholders immediately prior to the merger, consolidation or other reorganization maintain at least 50% of the voting power; (c) a majority of the incumbent members of the Board are replaced by Directors whose appointment or election is not endorsed by at least two-thirds of the Board; or (d) the acquisition by one person or more than one person acting as a group, of all or substantially all of the Company’s assets.

Unless otherwise provided in an award agreement, in the event of a participant’s termination of service without Cause or for Good Reason during the 18-month period following a Change in Control, the vesting of all awards will fully accelerate and all outstanding options and SARs will become immediately exercisable as of the date of the participant’s termination of service.

In the case of performance awards, in the event of a participant’s termination of service without Cause or for Good Reason, in either case, within 18 months following a Change in Control, all performance goals or other vesting criteria will be deemed achieved at 100% of target levels and all other terms and conditions will be deemed met as of the date of the participant’s termination of service.

39





In the event of a Change in Control, the Committee may in its discretion and upon at least 10 days’ advance notice to the affected persons, cancel any outstanding awards and pay to the holders the value of the awards based upon the price per share of common stock subjectreceived or to be received by other shareholders of the Company in the event. In the case of any option or SAR with an award.exercise price that equals or exceeds the price paid for a share of common stock in connection with the change in control, the Committee may cancel the option or SAR without the payment of any consideration.




As of April 12, 2016, we had issued 611,292 shares of restricted stock under the 2009 Plan, of which 454,634 have vested and become unrestricted.

Nonqualified Deferred Compensation

We adopted a Deferred Compensation Plan in December 2015, which permits eligible employees, including our NEOs, and our Directors to annually elect to defer a portion of their salary, commissions, cash bonus, Director fees and/or stock awards they would otherwise have received when earned.  Under this plan, participants can defer up to 90% of their salary, commissions, cash bonus, Director fees and stock awards. Cash amounts deferred under the Deferred Compensation Plan are deemed invested in the investment funds selected by the participant with similar options as available under the Company’s 401(k) Plan. We have option to contribute but do not currently contribute to the Deferred Compensation Plan on behalf of its participants or match the deferrals made by participants.

At the time of deferral, a participant must indicate whether he or she wishes to receive the amount deferred while in-service or upon separation of service. In either case, the payment will be in either a lump sum or in substantially equal annual installments. In-service installments cannot exceed five years, while installments elected to start upon separation of service cannot exceed ten years. If separation is due to a disability or a change in control, deferrals will be paid similar to deferrals paid upon separation of service, while deferrals related to death will be paid in a lump sum to the participant’s beneficiary. If a participant experiences an unforeseeable emergency during the deferral period, the participant may petition to receive a partial or full payout from the Deferred Compensation Plan. All distributions are made in cash, except for deferred stock awards which are settled in Company stock.

Potential Payments Upon Termination or Change of Control

Our 1998 Stock Option Plan and 2009 Restricted Stock/Unit2019 Equity Incentive Plan contains “change of control” provisions. These provisions are designed to provide some assurance that we will be able to rely upon each executive’s services and advice as to the best interests of Natural Gas Services Group and our shareholders without concern that the executive might be distracted by the personal uncertainties and risks created by any proposed or threatened change of control and to promote continuity of our executive team.

Under our stock option plan, the Committee may adjust the stock options held by our executives upon the occurrence of a change of control. With this authority, the Committee may in its discretion elect to accelerate the vesting of any stock options that were not fully vested and allow for the exercise of such options as to all shares of stock subject thereto.

Likewise, under our 2009 Restricted Stock/Unit2019 Equity Incentive Plan, in the event of a participant's termination without Cause or for Good Reason during the 18-month period following a change of control (as defined in control will accelerate the vesting ofplan), all awards under the plan unless the Committee has provided otherwise in a particular award under the plan.will immediately vest.  In addition, upon death disability or retirement,disability, any vesting or other restrictions on the restricted stock awards will accelerate or lapse such that all shares underlying a restricted stock award will become unencumbered.

As noted in the tables above and summarized below, our named executive officers have stock options and restricted stock awards which are subject to certain vesting requirements.

At December 31, 2015,2020, our named executive officers had the following number of unvested restricted stock awards which were subject to forfeiture as of that date:

Stephen C. Taylor -- 83,590210,149 shares
G. Larry Lawrence -- 20,000 shares
James R. Hazlett -- 20,00029,999 shares
James R. Lawrence -- 3,333 shares

42




Each of these restricted stock awards could have become vested and issued without restrictions on18 months after December 31, 20152020, assuming a change of control were to have occurred on that date.  In addition, the restricted stock awards would have been issued without restrictions on December 31, 2015,2020, assuming the named executive officer had died became disabled or retired.become disabled.  The closing price of our common stock on December 31, 2015,2020, was $22.30$9.48 per share.  Accordingly, on December 31, 2015, had there been a change in control event or had the named executive officer died, became disabled or retired, the vesting terms of the restricted stock awards would have lapsed and the shares would have become unrestricted.  As a result, there was a potential for Messrs. Taylor, Hazlett and J. Lawrence to realize immediate value upon the lapse of restrictions on restricted stock awards on December 31, 2020 as follows:  Mr. Taylor --$1,864,057;- $1,992,213; Mr. Lawrence --$446,000;Hazlett - $284,391; and Mr. Hazlett --$446,000.J. Lawrence - $31,597.


As described under “CompensationCompensation Agreements with Management”Management on page 41,47, we entered into a written employment agreement with Stephen C. Taylor, President, Chief Executive Officer and Chairman of the Board in October 2013.  Under the employment agreement, Mr. Taylor is eligible for certain benefits in connection with a change in control.  These provisions were included in Mr. Taylor’s initial employment agreement with us and were continued in his current agreement as part of our negotiations with Mr. Taylor as to the terms of his employment and as an inducement for him to continue his employ with our company.  The change of control and severance provisions were designed to promote stability and continuity with respect to Mr. Taylor’s employment as our President and Chief Executive Officer and President.Officer.

The following table summarizes the benefits in effect as of December 31, 2015 that Mr. Taylor would receive assuming that a qualifying termination (i.e., a termination described in footnote 2 below) in connection with a change in control, death or disability or a termination by the Company without cause, or a voluntary termination by Mr. Taylor with and without good reason, occurred on December 31, 2015. Those payments that are available generally to salaried employees that do not discriminate in scope, terms or operation in favor of executive officers are also not included in this table.

As a result of discussions with our stakeholders and CEO, the Compensation Committee intends to target quantitative-based incentive equity compensation at 175% of the CEO’s base salary.

Median annual total compensation of all employees (excluding Mr. Taylor)$70,002 
Annual total compensation of Mr. Taylor$3,188,949

Compensation of Directors

We use a combination of cash and equity-based incentive compensation to attract and retain qualified candidates to serve on our Board of Directors.  In setting compensation for our Directors, we consider the substantial amount of time that Directors expend in fulfilling their duties to us and our shareholders, as well as the skill-sets required to fulfill these duties.

The following table discloses the cash, equity awards and other compensation earned, paid or awarded, as the case may be, to each of our non-employee Directors during the fiscal years ended December 31, 2015, 20142020, 2019 and 2013.2018:

Equity Based Compensation Paid to Independent Directors

In 2013, each independent Director received a static grant of 2,500 shares of restricted shares of Company common stock for each year. Beginning in 2014, our Board of Directors revised the Company'sOur compensation policy for independent directors so that in lieu of issuing a static 2,500 restricted shares of Company common stock as in past years, the independent directors now receiveDirectors is to grant an annual award of restricted shares based upon a review of equity award values paid by other public companies in the Company's peer group and the Company's market and financial performance in comparison to such peer group companies. For 2015,2020, based upon the Company's performance compared to its peer group, the Compensation Committee recommended and the Board approved an equity award value of approximately $103,000$100,000 in restricted stock.stock/units. In connection therewith, each of our four independent directorsDirectors was granted for 20152020 the amount of 5,4924,432 restricted shares/units, pursuant to the 2019 Equity Incentive Plan, which was calculated by dividing $50,000 by a deemed share price of $11.28 (two times the market closing price of $5.64 on April 28, 2020) that effectively reduced each independent Director's restricted stock award by 50% and their total awards by 25%. The restricted shares/units vest one year from the date of grant.

On April 1, 2021, William F. Hughes retired and resigned from his position as a member of the Board of Directors of the Company. In recognition of Mr. Hughes’ longstanding service, the Compensation Committee voted to accelerate the vesting of the following unvested shares, free of any further restrictions:

3,989 restricted stock units

443 restricted stock awards

On March 18, 2021, the Compensation Committee recommended and the Board approved the continuation of its annual equity award policy of $100,000 in value of restricted stock, for 2020. However, because of the depressed nature of the energy industry and dilutive nature of the Company’s stock at current market prices, the Board determined to modify this year’s award into a 50/50 split of stock and cash. In connection therewith, three independent Directors were granted the following:

An award of $50,000 in cash (50% of the total) that vests one year from the date of grant; and
An award of 5,612 shares of restricted stock, pursuant to the Plan, based upon the closingwhich was calculated by dividing $50,000 by a deemed share price of $18.75 per share as$8.91. These awards of March 19, 2015,restricted stock vest one year from the date of the grant. The restricted shares are subject to vesting whereby no shares will vest during the first year,grant and then upon the first anniversary date of the award, one-fourth of the shares will vest every three months so that all restricted shares will have vested on the second anniversary date of the grant of the award. Notwithstanding the vesting schedule, all of the restricted shares are subject to acceleration and will immediately vest in certain events.

On April 1, 2021, the case of (i) death, disability, or retirementBoard appointed Nigel J. Jenvey as a Director of the recipient employee, or (ii)Company. Consistent with the compensation of the other non-employee Directors, the Compensation Committee awarded Mr. Jenvey the following:

An award of 5,291 shares of restricted stock, which was calculated by dividing $50,000 by a changedeemed share price of control$9.45.

Compensation Agreements with Management

On October 23, 2013, we and Stephen C. Taylor entered into a new employment agreement with us (the “Employment Agreement”), pursuant to which Mr. Taylor continues his employment as our President and Chief Executive Officer. The new Employment Agreement became effective on the same date and Mr. Taylor’s previous employment agreement with us, which was set to expire on October 25, 2013, was terminated in connection therewith.

On April 24, 2015, we entered into an amendment with Mr. Taylor to his Employment Agreement pursuant to which the "modified single trigger" change of control provision was changed to a "double trigger" change of control.

Under the new "double trigger" change of control provision, a change of control must occur followed by the Company or its successor terminating Mr. Taylor's employment other than for cause, death, or disability, or by Mr. Taylor terminating his employment for Good Reason.

Limitation on Directors’ and Officers’ Liability

Our Articles of Incorporation provide our Directors and Officers with certain limitations on liability to us or any of our shareholders for damages for breach of fiduciary duty as a Director or officer involving certain acts or omissions of any such Director or Officer.

This limitation on liability may have the effect of reducing the likelihood of derivative litigation against Directors and Officers, and may discourage or deter shareholders or management from bringing a lawsuit against Directors and Officers for breach of their duty of care even though such an action, if successful, might otherwise have benefited our shareholders and us.

Our Articles of Incorporation and bylaws provide certain indemnification privileges to our Directors, employees, agents and officers against liabilities incurred in legal proceedings.  Also, our Directors, employees, agents or officers who are successful, on the merits or otherwise, in defense of any proceeding to which he or she was a party, are entitled to receive indemnification against expenses, including attorneys’ fees, incurred in connection with the proceeding.

We are not aware of any pending litigation or proceeding involving any of our Directors, Officers,officers, employees or agents as to which indemnification is being or may be sought, and we are not aware of any other pending or threatened litigation that may result in claims for indemnification by any of our Directors, officers, employees or agents.

Even though we maintain Directors’ and Officers’ liability insurance, the indemnification provisions contained in our Articles of Incorporation and bylaws remain in place.






Procedures for Reviewing Certain Transactions

On March 7, 2007, we adopted a written policy for the review, approval or ratification of related party transactions. All of our officers, Directors and employees are subject to the policy. Under this policy, the Audit Committee will review all related party transactions for potential conflict of interest situations. Generally, our policy defines a “related party transaction” as a transaction in which we are a participant and in which a related party has an interest. A “related party” is:

any of our Directors, Officers or employees or a nominee to become a Director;

an owner of more than 5% of our outstanding common stock;

certain family members of any of the above persons; and

any entity in which any of the above persons is employed or is a partner or principal or in which such person
has a 5% or greater ownership interest.


Approval Procedures

Before entering into a related party transaction, the related party or our department responsible for the potential transaction must notify the CEO or the Audit Committee of the facts and circumstances of the proposed transaction.  If the amount involved is equal to or less than $100,000, the proposed transaction will be submitted to the CEO.  If the amount involved exceeds $100,000, the proposed transaction will be submitted to the Audit Committee.  Matters to be submitted will include:

the related party’s relationship to us and interest in the transaction;

the material terms of the proposed transaction;

the benefits to us of the proposed transaction;

the availability of other sources of comparable properties or services; and

whether the proposed transaction is on terms comparable to terms available to an unrelated third party or to employees generally.

The CEO or the Audit Committee, as applicable, will then consider all of the relevant facts and circumstances available, including the matters described above and, if applicable, the impact on a director’sDirector’s independence.  Neither the CEO

48




nor any member of the Audit Committee is permitted to participate in any review, consideration or approval of any related party transaction if such person or any of his or her immediate family members is the related party. After review, the CEO or the Audit Committee, as applicable, may approve, modify or disapprove the proposed transaction. Only those related party transactions that are in, or are not inconsistent with, our best interests and that of our shareholders will be approved.


Ratification Procedures

If one of our officers or Directors becomes aware of a related party transaction that has not been previously approved or ratified by the CEO or the Audit Committee, then, if the transaction is pending or ongoing, the transaction must be submitted, based on the amount involved, to either the CEO or the Audit Committee and the CEO or the Audit Committee willto consider the matters described above. Based on the conclusions reached, the CEO or the Audit Committee, as applicable, will evaluate all options, including ratification, amendment or termination of the related party transaction. If the transaction is completed, the CEO or the Audit Committee will (i) evaluate the transaction, taking into account the same factors as described above, to determine if rescission of the transaction or any disciplinary action is appropriate,appropriate; and (ii) will request that we evaluate our controls and procedures to determine the reason the transaction was not submitted to the CEO or the Audit Committee for prior approval, and whether any changes to the procedures are recommended.

We did not have any related party transactions in 20152020 with our Officersofficers or Directors.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), gives the shareholders the  right to endorse or not endorse the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the SEC's rules.  The proposal, commonly known as a “Say-on-Pay” proposal, gives our shareholders the opportunity to express their views on the Company's executive compensation.  

At the Company's annual meeting of shareholders held in June 2011, our shareholders recommended that the advisory vote on the Say-on-Pay of our named executives in our proxy materials be submitted annually, notwithstanding that our Board of Directors recommended that the advisory vote be submitted every third year. In light of the recommendation of the shareholders, we decided to include the Say-on-Pay advisory vote in our proxy materials on an annual basis until the next shareholder vote on the frequency of Say-on-Pay or our Board of Directors otherwise determines that a different frequency of Say-on-Pay vote is in the best interests of the shareholders.
We are asking our shareholders to indicate whether or not they support the compensation program as described in this proxy statement.  This proposal is not intended to address any specific item of compensation, but rather the overall compensation of the named executive officers and the compensation policies, methodologies and practices described in this proxy statement.  Accordingly, we ask our stockholders to vote “FOR” the following resolution at our annual meeting:
“RESOLVED, that the shareholders approve the compensation of the Company's named executive officers, as disclosed in the compensation section, the compensation tables, and the related disclosure contained in the proxy statement set forth under the caption “Executive Compensation” of this proxy statement.”
The Company believes its compensation philosophy and programs are strongly linked to performance and results and appropriately aligned with the interests of shareholders.  Our compensation philosophy is to provide an executive compensation program that:
rewards performance and skills necessary to advance our objectives and further the interests of our officersshareholders;  
is fair and directors inadvertently failedreasonable and appropriately applied to timely file Form 4's relating toeach executive officer;     
is competitive with compensation programs offered by our competitors; and     
is appropriately focused on achieving annual financial and operational goals through the disposalCompany's cash bonus plan and on maximizing stockholder value over the long term, through grants of restricted shares and stock options.

The Board of Directors recommends that you vote FOR approval, on an advisory basis, of the number of  shares listed in connection with


their election to withhold shares in payment of income tax obligations arising from the vesting of the awards: David Bradshaw - 206 shares; John Chisholm - 206 shares; James R. Hazlett - two transactions of 1,088 and 4,066 shares; G. Larry Lawrence - two transactions of 1,088 and 4,067 shares; and Stephen C. Taylor - 20,547 shares.  Appropriate Form 4's were filed in June 2015 when the error was discovered.

In addition, in December of 2015 Charles G. Curtis inadvertently failed to timely file a Form 4 in connection with the exercise of a stock option for 2,500 sharescompensation programs of our common stock.  Mr. Curtis filed a Form 4 reportingnamed executive officers as disclosed in the missed transactionCompensation Discussion and Analysis, the compensation tables, and the related disclosure contained in January 2016.the proxy statement set forth under the caption “Executive Compensation” of this proxy statement.

PROPOSAL 3 - APPROVAL OF THE AMENDMENT AND RESTATEMENT OF THE 1998 STOCK OPTION PLAN



Proposal

To consider and vote upon a proposal to amend and restate the Natural Gas Services Group, Inc. Stock Option Plan to (1) increase the number of shares authorized for issuance thereunder from 750,000 to 1,000,000 shares of common stock and (2) extend the term of the Plan for an additional ten years, until February 28, 2026.


History of the Plan and Description of the Proposed Amendment

On December 18, 1998, the Board of Directors adopted the 1998 Stock Option Plan of Natural Gas Services Group, Inc. (the “1998 Plan” or simply the “Plan”), and directed that the 1998 Plan be submitted to the shareholders for approval. The 1998 Plan became effective when it received such approval on December 18, 1998. On May 9, 2006, the Compensation Committee of the Board of Directors voted to amend the 1998 Plan and the amendments were approved by our shareholders at our 2006 Annual Meeting of Shareholders (the “2006 Plan”). The 2006 Plan amendments, among other things, extended the terms of 1998 Plan until March 1, 2016 and increased the number of shares of common stock issuable under the 2006 Plan from 150,000 to 550,000. On April 15, 2009, the Compensation Committee of the Board of Directors voted to further amend the Plan to add an additional 200,000 shares of common stock to the Plan, thereby authorizing the issuance of up to 750,000 shares of common stock under the Plan and the amendment was approved at our 2009 Annual Meeting of Shareholders.

On April 5, 2016, subject to shareholder approval, the Board of Directors voted to amend and restate the Plan to extend the Plan until February 28, 2026 (the “2016 Plan” or simply the “Plan”) and increase the number of shares of common stock issuable under the Plan from 750,000 to 1,000,000.

The 2016 Plan amendment will become effective if a majority of the votes cast are in favor of the proposal. If the amendment is not approved, no further options may be granted under the 2006 Plan, although all options granted prior to March 1, 2016, which continue to be outstanding, will remain in force until such time as the options are either exercised or expire pursuant to the terms set forth in such options.

The purposes of the Plan, which are unchanged by the proposed amendment, are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to employees and consultants and to promote the success of our business.

Summary Description of the Plan

The following summary of the Plan, as amended and restated, is qualified in its entirety by reference to the text of the Plan, as amended and restated, which is attached as Appendix A. The Plan has been and will continue to be administered by the Compensation Committee of the Board of Directors. The Compensation Committee has full and final authority, in its discretion, to grant incentive stock options or non-statutory stock options, to select the persons who would be granted stock options and determine the number of shares subject to each option, the duration and exercise period of each option and the terms and conditions of each option granted.

The Major Provisions of the Plan as amended and restated are as follows:

Eligibility. The Compensation Committee is authorized to grant stock options to any person selected by the Compensation Committee, including employees, officers who are also directors of Natural Gas Services Group, directors who are not employees of Natural Gas Services Group and consultants. Incentive stock options may be granted only to employees of Natural Gas Services Group.

Option Price. The option exercise price for shares of common stock issued upon exercise of an option is such price as is determined by the Compensation Committee. However, for incentive stock options granted to employees the option price will be not less than 100% of the fair market value of the Company’s common stock on the date the option is granted, except that if an incentive stock option is granted to an employee who owns more than 10% of our outstanding common stock, the option price will be not less than 110% of the fair market value of the common stock on the date of grant. Fair market value for purposes of the Plan is the closing price of the common stock as reported on the New York Stock Exchange on the relevant date.



Duration of Options. Each stock option will terminate on the date fixed by the Compensation Committee, which shall be not more than ten years after the date of grant. However, in the case of an incentive stock option granted to an employee who, at the time the option is granted, owns stock representing more than 10% of the our outstanding stock, the term of the option will be five years from the date of grant or such shorter time as may be provided in the stock option agreement.

Exercise Period. In the case of incentive stock options, if an optionee’s employment is terminated for any reason, except death or disability, the optionee has three months in which to exercise an option (but only to the extent exercisable on the date of termination) unless the option by its terms expires earlier. If the employment of the optionee terminates by reason of total and permanent disability, the option may be exercised during the period of twelve months following termination of employment. If an optionee dies while an employee or within three months from the date of termination, the right to exercise shall terminate twelve months from the date of death. The options terminate immediately prior to the dissolution or liquidation of Natural Gas Services Group, unless the Compensation Committee gives each optionee the right to exercise his option as to all or any part of the option, including shares as to which the option would not otherwise be exercisable. If we sell all or substantially all of our assets or we merge with or into another entity in a transaction in which it is not the survivor, options will be assumed or an equivalent option will be substituted by the successor corporation, unless the Compensation Committee determines that the optionee has the right to exercise the option as to all of the shares, including shares as to which the option would not otherwise be exercisable. The Compensation Committee has the right to alter the terms of any option at grant or while outstanding pursuant to the terms of the Plan.

Payment. Payment for stock purchased on the exercise of a stock option must be made in full at the time the stock option is exercised. The Compensation Committee may, in its discretion, permit payment for the exercise price to be made in cash, check, other shares of common stock having a fair market value on the date of exercise equal to the aggregate exercise price of the shares as to which the option is exercised, or any combination of such methods of payment, or such other consideration and method of payment for the issuance of shares as permitted under the Colorado Business Corporation Act.

Shares That May Be Issued under the Plan. Prior to the increase in authorized shares set forth in this proposal, a maximum of 750,000 shares of our common stock, as may be adjusted as described below, may be issued upon exercise of stock options granted under the Plan. This number includes the number of shares of Natural Gas’ common stock originally authorized in 1998 (150,000 shares) plus the additional shares added in the 2006 and 2009 amendments (600,000 shares). In connection with extending and restating the Plan, a total of 250,000 additional shares will be authorized pursuant to this proposed amendment. The 250,000 additional shares available represent approximately 1.9% of our common stock issued and outstanding on April 18, 2016. At the date of this proxy statement, 241,812 shares of common stock have already been issued under the Plan and 414,769 shares are subject to currently outstanding stock options, leaving 93,419 shares of common stock available from the 750,000 shares authorized prior to this proposal. The number of shares available under the Plan is subject to adjustment in the event of any stock split, stock dividend, recapitalization, spin-off or other similar action. If any stock option terminates or is canceled for any reason without having been exercised in full, the shares of stock not issued will then become available for additional grants of options.

Federal Income Tax Consequences Federal Income Tax Consequences

Incentive Stock Options. Some of the options granted under the Plan may constitute “incentive stock options” (“ISOs”) within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). Under current federal income tax rules, there will be no federal income tax consequences to us or an optionee upon the grant of an ISO, nor will an optionee’s exercise of an ISO result in income recognition to the optionee or a deduction or other federal income tax consequences to Natural Gas Services Group. Although an optionee will not realize ordinary income upon his exercise of an ISO, the excess of the fair market value of the common stock acquired at the time of exercise over the option price may constitute an adjustment in computing alternative minimum taxable income under Section 56 of the Code and, thus, may result in the imposition of the “alternative minimum tax” pursuant to Section 55 of the Code on the optionee. The tax consequences of a disposition of stock acquired upon exercise of an ISO depends upon how long the optionee has held the shares. If an optionee does not dispose of common stock acquired through an ISO within two years after the ISO was granted, nor within one year of the ISO’s date of exercise, any gain realized upon a subsequent disposition of common stock will constitute long-term capital gain (or loss) to the optionee equal to the difference between the sale price of the shares and the exercise price. We are not entitled to any deduction under these circumstances. If the optionee fails to satisfy either of the foregoing holding periods, he must recognize ordinary income in the year of the disposition, which is referred to as a “disqualifying disposition”. Upon the occurrence of a disqualifying disposition of an ISO, the amount of such ordinary income generally is the lesser of (i) the excess of the fair market value of the common stock on the date of exercise over the option price or (ii) the actual gain realized upon such disposition. Any gain in excess of the amount taxed as ordinary income will be treated as a long-term or short-term capital gain, depending on how long the stock was held (currently a period of more than one year). We will receive a deduction in the amount equal to the amount constituting ordinary income to an optionee in the year of the disqualifying disposition (in addition to the employer’s side of payroll/withholding taxes paid).



Non-statutory Options. Certain stock options which do not constitute ISOs (“non-statutory options”) may also be granted under the Plan. Under current federal income tax rules, there will generally be no federal income tax consequences to us or the optionee upon the grant of a non-statutory option so long as the exercise price of the option is equal to or exceeds the fair market value of the underlying stock as of the date of grant. However, the optionee will realize ordinary income upon the exercise of a non-statutory option in an amount equal to the excess of the fair market value of the common stock acquired upon the exercise of such option over the option price. We are required to pay the applicable payroll taxes on such income of the optionee, and we are required to withhold and pay over to the relevant tax authorities the applicable income tax withholding and employee portion of payroll taxes on this income (which the optionee is required to pay over to us). We will receive a corresponding deduction in the amount of the income recognized by the optionee (subject to possible limitations imposed by Section 162(m) of the Code) , as well as a deduction for the employer’s portion of payroll taxes paid. Any gain or loss realized upon the optionee’s subsequent disposition of such common stock will constitute short-term or long-term capital gain or loss depending on the optionee’s holding period following the date of exercise (currently a period of more than one year). We do not receive a tax deduction for any such capital gain.

The federal income tax consequences described in this section are based on laws and regulations in effect on the date of this proxy statement, and there is no assurance that the laws and regulations will not change in the future and affect the tax consequences of the matters discussed in this section.

Termination of and Amendments to the Plan
The Board of Directors may terminate or amend the Plan from time to time in any manner permitted by applicable laws and regulations, except that no additional shares of our common stock may be allocated to the Plan and no change in the class of employees eligible to receive incentive stock options or any other material amendment to the Plan may be made without the approval of the shareholders.


Market Price of the Company's Common Stock

The closing market price of our common stock as reported on the New York Stock Exchange for April 18, 2016 was $22.17 per share.

Estimate of Benefits

Generally, awards under the Plan are subject to the discretion of the Committee, and no determination has been made as to the types or amounts of awards that will be granted in the future to specific individuals pursuant to the Plan. Therefore, it is not possible to determine the future benefits that will be received by all potential participants. However, for illustrative purposes, 50,000 options were granted to 17 employees under the Plan during the fiscal year ended December 31, 2015.

     Although executive officers and members of our Board of Directors are eligible to receive awards under the Plan, since 2006, awards under the Plan have been made exclusively to non-executive employees of the Company.

Dilution, Burn Rate and Overhang

We actively manage our long-term dilution by limiting the number of shares subject to equity awards that we grant annually, expressed as a percentage of weighted average common shares outstanding and referred to as burn rate. Burn rate is another measure of dilution that shows how rapidly a company is depleting its shares reserved for equity compensation plans and measures the potential dilutive effect of annual equity grants. Our burn rate for 2015 was 1.5%.

An additional metric that we use to measure the cumulative impact of our equity programs is overhang (number of shares subject to equity awards outstanding under our equity plans but not exercised or settled, plus number of shares available to be granted, divided by weighted average common shares outstanding plus available equity awards under our equity plans). Our overhang as of December 31, 2015 was 7.7%. If the proposal to extend the Plan and increase the shares reserved for issuance under the plan by 250,000 shares is approved, our overhang as of that date would increase to 9.4% and then would be expected to decline over time.

The following are the factors that were material to the evaluation of the Compensation Committee and Board, with input from management, in determining acceptable and targeted levels of dilution: competitive data from relevant peer companies, the current and future accounting expense associated with the Company's equity award practices, and the influence of shareholder advisory firms. The Company's equity programs are revisited at least annually and assessed against these (and other) measures. We believe that the Company's burn rate and overhang (with or without the extension and additional shares requested under the Plan) are reasonable and reflect a prudent use of equity for compensation purposes.

Summary

We strongly believe the approval of the amended and restated Plan which extends the plan for an additional 10-year term and increases the number of authorized shares for issuance from 750,000 to 1,000,000 is essential to our continued success. Awards such as those provided under the Plan provide an important incentive for participants and will help us to attract, retain and motivate qualified individuals to serve on behalf of our company.

Vote Required

Approval of this proposal requires the affirmative vote of the holders of a majority of the shares casting votes in person or by proxy on this proposal at the Annual Meeting. The number of such affirmative votes must be at least a majority of the required quorum for the meeting.






Recommendation of the Board of Directors

The Board believes the proposed amendments to and restatement of the Plan are in the best interests of Natural Gas Services Group and its shareholders, as the availability of an adequate number of shares reserved for grant under the Plan and the other amended terms described above will assist in the recruitment and retention of the best available personnel.

The Board of Directions of Natural Gas Services Group recommends a vote "FOR" the proposal to amend and restate the Stock Option Plan, a copy which is included in this Proxy Statement as Appendix A. Proxies received by the Board of Directors will be so voted unless shareholders specify in their proxies a contrary choice.

The Board of Directors recommends that the shareholders vote “FOR” the ratification of the appointment of BDO USA, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2016.



PROPOSAL 5 - CONSIDERATION OF AN AMENDMENT TO THE COMPANY’S BYLAWS TO IMPLEMENT A MAJORITY VOTING STANDARD IN UNCONTESTED ELECTIONS OF DIRECTORS

Background

The Company has received a proxy statement proposal from a shareholder under Securities and Exchange Commission Rule 14a-8 requesting that a proposal be included in this Proxy Statement which would require the Board of Directors to initiate the appropriate process to provide that director nominees be elected by the affirmative vote the majority votes cast at an annual meeting in connection with uncontested elections. For reasons set forth below, and consistent with recent corporate governance initiatives described in this proxy statement, the Board of Directors agreed with the request and has initiated the process.

Amendment
56
The Board of Directors has adopted and recommends that shareholders approve an amendment (the “Amendment”) to the Company’s Bylaws to implement a majority voting standard for the election of directors in uncontested elections. A copy of the proposed amendment to the Bylaws is attached as

Appendix B to this Proxy Statement. 

Implementation and Purpose of the Amendment
Section 7-107-209 of the Colorado Business Corporation Act (the “Act”) and the Company's Bylaws provide that directors are elected by a plurality of the votes cast by the shares entitled to vote in the election at a meeting in which a quorum is present. Under plurality voting, director nominees receiving the greatest number of votes “for” election (although not necessarily a majority) are elected as directors.

Section 7-107-208 of the Act provides that a Colorado corporation may impose a greater voting requirement for the election of directors, if authorized by its articles of incorporation or, if authorized by the articles of incorporation, through bylaws adopted by the shareholders. The Company's Articles of Incorporation provide that the Bylaws may provide for a greater voting requirement as long as such Bylaws are adopted by the Company's shareholders.

Considering the foregoing, the Board of Directors has amended Section 10 of Article II of the Bylaws to provide for a majority voting standard in uncontested director elections. Under the new majority voting standard, a nominee for director in an uncontested election shall be elected to the Board if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election. For this purpose, abstentions and broker non-votes will not count as votes cast. Directors will continue to be elected by plurality vote at any meeting of shareholders where the number of director nominees exceeds the number of directors to be elected, commonly referred to as a contested election. In the event a director fails to receive a majority of the votes cast in an uncontested election, the Board of Directors may, within its powers, decrease the number of directors, fill the vacancy, or take other appropriate action.

The transition from plurality voting to majority voting in the election of Directors is a current trend in corporate governance, with a significant majority of the companies in the S&P 500 having adopted the majority vote standard. By requiring that a Director nominee receive a majority of the votes cast (excluding abstentions and broker non-votes) in favor of his or her election to the Board of Directors, shareholders are provided with a more meaningful role in the election of Directors. Under the Company's current plurality voting standard in connection with uncontested elections, a nominee for the Board can be elected with as little as a single affirmative vote, because withheld votes have no effect.

If this proposal is approved by our shareholders, the Board of Directors will revise its director resignation policy to provide that any incumbent director who does not receive a majority of the votes cast is required to tender his or her resignation.
The Board continues to believe that the plurality vote standard should continue to apply in contested director elections. If a majority vote standard is used in a contested election, fewer candidates could be elected to the Board than the number of authorized board seats if too many directors receive more “against” than “for” votes. Therefore, the Amendment retains plurality voting in contested director elections.






Vote Required

Approval of this proposal requires the affirmative vote of the holders of a majority of the shares casting votes in person or by proxy on this proposal at the Annual Meeting. The number of such affirmative votes must be at least a majority of the required quorum for the meeting.

Effective Date
If approved by the Company’s shareholders, the Amendment will become immediately effective. The new majority voting standard would then be applicable to an uncontested election of directors at the Company’s 2017 annual meeting of shareholders.
Our Board of Directors recommends a vote "FOR" approval of the amendment to the Bylaws to implement a majority voting standard in uncontested elections of Directors.








SHAREHOLDER PROPOSALS

Under SEC Rule 14a-8, if a shareholder wants us to include a proposal in our proxy statement and form of proxy for presentation at our 201720222 Annual Meeting of Shareholders, the proposal must be received by us at our principal executive offices at 508 West Wall Street,404 Veterans Airpark Lane, Suite 550,300, Midland, Texas 7970179705 by December 19, 2016,January 1, 2022 unless the date of our 20172022 Annual Meeting of Shareholders is more than 30 days from the anniversary date of our 20162021 Annual Meeting of Shareholders, in which case the deadline is a reasonable time before we print and mail our proxy materials for the 20172021 Annual Meeting of Shareholders. The proposal should be sent to the attention of the Corporate Secretary of Natural Gas Services Group.

Rule 14a-4 of the SEC's proxy rules allows a company to use discretionary voting authority to vote on matters coming before an annual meeting of shareholders for the prior year's annual meeting of shareholders or the date specified by an overriding advance notice provision in the company's bylaws. Our bylaws do not contain such an advance notice provision. Accordingly, for our 2017 annual meeting, shareholders' written notices must be received by us before March 9, 2017 for any proposal a shareholder wishes to bring before the meeting but for which such shareholder does not seek to have a written proposal considered for inclusion in the proxy statement and form of proxy. Your notice should be addressed to President, Natural Gas Services Group, Inc., 508 West Wall Street, Suite 550, Midland, Texas 79701.
In order to curtail controversy as to the date on which a proposal was received by us, it is suggested that proponents submit their proposals by certified mail-return receipt requested. Such proposals must also meet the other requirements established by the SEC for stockholder proposals.

In addition, pursuant to our Bylaws, a stockholder who intends to nominate a candidate for election to the Board or to propose other business for consideration at the 2022 Annual Meeting of Stockholders must deliver to the Company notice and certain information concerning themselves and their shareholder proposals.

proposal or director nomination not less than 90 days nor more than 120 days prior to the anniversary date of the immediately preceding annual meeting (the “annual meeting anniversary date”); provided, however, that, if the annual meeting is scheduled to be held on a date more than 30 days before or more than 60 days after the annual meeting anniversary date, notice must be delivered to us not later than the close of business on the later of the 120th day prior to the scheduled date of such annual meeting and not later than the latest of (i) the 90th day prior to such annual meeting, or (ii) the 10th day after public disclosure of the date of such annual meeting.

Accordingly, any notice given by or on behalf of a stockholder pursuant to these provisions of our Bylaws (and not pursuant to Rule 14a-8 of the Exchange Act) must be received no earlier than February 17, 2022, and no later than March 18, 2020 Such notice should be addressed to: Natural Gas Services Group, Inc., Corporate Secretary, at 404 Veterans Airpark Lane, Suite 300, Midland, Texas 79705.

With respect to special meetings of the shareholders, the business that may be brought at the meeting will be limited to that stated in the Company's notice of meeting. In the event we call a special meeting of shareholders for the purpose of electing one or more directors to the Board, any such shareholder entitled to vote in such election of directors may nominate a person or persons (as the case may be) for election to such position(s) as specified our notice of meeting, if such shareholder delivers a notice that complies with the requirements of our Bylaws to the secretary of the Company at its principal executive offices not earlier than the close of business on the 120th day prior to such special meeting and not later than the close of business on the later of: (x) the 90th day prior to such special meeting; or (y) the tenth (10th) day following the first date of public disclosure of the date of the special meeting and of the nominees proposed by the Board.

These requirements are separate from and in addition to the SEC’s requirements described in the first paragraph of this section relating to including a proposal in our proxy statements.
