How CEO Pay is Tied to Cimarex's Performance (page 46)

Our compensation programs are designed to align performance incentives with the long-term interests of our shareholders. The programs also provide competitive total direct compensation opportunities that retain, and attract when needed, executive talent and link compensation earned to achievement of short- and long-term financial and operational objectives. Our Compensation and Governance Committee considers performance in two primary ways:

•

Cimarex's operating performance; and



•

Return to shareholders over time, on both an absolute basis and a relative basis compared to other companies in the S&P Oil & Gas Exploration & Production index and our Compensation Peer Group (see page 36).

2017 Financial and Operating Highlights

•

Exploration and development expenditures increased 74% to $1,281.1 million compared to $734.8 million in 2016, while year-over-year average daily production increased 19% to 1,142.1 MMcfe per day.



•

While total production expense increased by approximately $30.2 million, or 13%, from $232.0 million in 2016 to $262.2 million in 2017, our Operations group excelled at optimizing our production. As a result, our production expense per Mcfe declined almost 5% from $0.66 per Mcfe in 2016 to $0.63 per Mcfe in 2017, and declined 42% in 2017 compared to 2014.



•

We incurred no additional debt and had cash on hand of $400.5 million at year-end 2017.



•

Year-over-year production revenues increased 53% to $1.9 billion as revenues were positively affected by increased realized commodity prices as well as increased production, which resulted in net income of $494.3 million in 2017 after losses in each of 2016 and 2015.



•

Cash flow provided by operating activities of $1.1 billion was 75% higher than that of the prior year.



•

During 2017, our overall estimated proved reserves increased 16% after additions, positive and negative revisions, and production. We added 940.7 Bcfe of proved reserves through extensions and discoveries in the Mid-Continent and Permian Basin, where we added 282.9 Bcfe and 657.8 Bcfe, respectively. In addition, we had net negative revisions of previous estimates of 59.7 Bcfe. Revisions were comprised of an increase of 45.8 Bcfe for net positive performance revisions, a decrease of 43.9 Bcfe related to higher operating expenses, an increase of 187.2 Bcfe for positive revisions due to higher commodity prices, and a decrease of 248.8 Bcfe for the removal of proved undeveloped reserves, the development of which likely will be delayed beyond five years from our initial disclosure.



•

As a result of our strong financial and operation performance in 2017, we continued to outperform our peers in a difficult macro-economic energy environment. Our relative three-year stock price performance as compared to our peer group performed at the 78th percentile.

QUESTIONS AND ANSWERS

PROXY MATERIALS AND VOTING INFORMATION

We are providing these materials in connection with the solicitation by the Board of Directors of Cimarex Energy Co., a Delaware corporation, of proxies to be voted at our 2018 Annual Meeting of Shareholders and at any adjournment or postponement of the Meeting. The Meeting will take place on May 10, 2018, beginning at 9:00 a.m. Central Daylight Time, at the Hyatt Regency Tulsa, 100 East 2^nd Street, Tulsa, Oklahoma 74103.

If your shares are registered directly in your name with Cimarex's registrar and transfer agent, Continental Stock Transfer & Trust Company, you are considered a shareholder of record with respect to these shares. If your shares are held in a brokerage account or bank, broker or other nominee, you are considered the beneficial owner of these shares.

If you are a shareholder of record, you should receive only one proxy card for all the shares you hold of record in certificate form and in book-entry form. If you receive more than one proxy card, please vote all proxy cards received.

If you are a Cimarex employee, you will receive a proxy or voting instruction card for all the shares you hold in the Cimarex 401(k) Plan. Your proxy card will serve as a voting instruction card for the Plan trustee. If you do not specify your voting instructions on the proxy card, the Plan trustee will vote your shares in the same proportion as it votes shares for which it did receive timely instructions. To allow sufficient time for voting by the trustee, your voting instructions must be received no later than 11:59 p.m. Eastern Daylight Time on May 7, 2018.

By Written Proxy.    All shareholders of record can vote by written proxy card. If you are a shareholder of record and receive a notice regarding the availability of proxy materials, you may request a written proxy card by following the instructions included in the notice. If you are a beneficial owner, you may request a written proxy card or a voting instruction form from your bank, broker or other nominee.

By Telephone or Internet.    All shareholders of record can vote by calling the toll-free telephone number on the proxy card. Please have your proxy card when you call. Voice prompts will direct you on how to vote your shares and will confirm your voting instructions have been recorded properly.

Shareholders also may vote on the internet by accessing the website noted on the proxy card. Please have your proxy card when you go to the website. As with telephone voting, you can confirm your voting instructions have been recorded properly.

Beneficial owners may vote by telephone or internet if their bank, broker or other nominee makes those methods available, in which case the bank, broker or other nominee will include the instructions with the proxy materials.

Table of Contents

As a beneficial owner, in order to ensure your shares are voted in the way you would like, you must provide voting instructions to your bank, broker or other nominee by the deadline provided in the materials you receive from your bank, broker or other nominee. If you do not provide voting instructions to your bank, broker or other nominee, whether your shares can be voted by such person depends on the type of item being considered to vote.

Non-Discretionary Items.    The election of Directors and the advisory vote to approve executive compensation are non-discretionary items and may not be voted on by brokers, banks or other nominees who have not received specific voting instructions from beneficial owners.

Discretionary Items.    The ratification of the appointment of KPMG LLP as Independent Auditors is a discretionary item. Generally, banks, brokers and other nominees that do not receive voting instructions from beneficial owners may vote on the proposal in their discretion.

Table of Contents

Item 1. Election of Three Class I Directors.    If you abstain from voting in the election of Directors, you will be treated as not having cast a vote and the abstention will not be counted in determining the outcome of the election. Broker non-votes are not considered a vote cast under our Bylaws and will have no effect on the outcome of the election of Directors.

Item 2. Advisory Vote to Approve Executive Compensation.    If you abstain from voting on the advisory vote to approve executive compensation, you are considered present and entitled to vote, and your shares are considered in the calculation of whether Item 2 received the affirmative vote of a majority of shares present and entitled to vote. The effect of an abstention is a vote against Item 2. Broker non-votes are not considered in the calculation of a majority of shares present and entitled to vote.

Item 3. Ratification of Appointment of KPMG as Independent Auditors.    If you abstain from voting on the ratification of KPMG LLP as Cimarex's Independent Auditors, you are considered present and entitled to vote, and your shares are considered in the calculation of whether Item 3 received the affirmative vote of a majority of shares present and entitled to vote. The effect of an abstention is a vote against Item 3. Because Item 3 is a routine matter on which a broker has discretionary authority, no or few broker non-votes likely will result from this Item.

You may revoke your proxy prior to the completion of voting by:

•

Giving written notice to Cimarex's Corporate Secretary;

•

Delivering a valid, later-dated proxy, or a later-dated vote by telephone or on the internet in a timely manner; or

•

Voting by ballot at the Annual Meeting.

We are distributing our proxy materials to certain shareholders via the internet under the "notice and access" approach permitted by the SEC. On or about March 30, 2018, we will mail to certain of our shareholders a notice of internet availability of proxy materials with instructions explaining how to access our proxy statement and annual report and how to vote online. If you receive a notice of internet availability by mail, you will not receive a printed copy of the proxy materials in the mail unless you request them by following the instructions for requesting such materials included in the notice of internet availability.

Even if you do not participate in "notice and access," the Notice of Annual Meeting and proxy statement are available on the internet at http://www.allianceproxy.com/cimarex/2018.

Alliance Advisors LLC, our proxy solicitor, will tabulate the votes and, Francis B. Barron, Cimarex's Corporate Secretary, will act as inspector of election.

We will announce the preliminary voting results at the Annual Meeting of Shareholders. Cimarex will report the final results in a Current Report on Form 8-K filed with the SEC after the Meeting.

We bear all expenses incurred in connection with the solicitation of proxies. We hired Alliance Advisors LLC to assist with the solicitation of proxies for an estimated fee of $10,000 plus expenses. We will reimburse brokers, fiduciaries and custodians for their costs in forwarding proxy materials to beneficial owners of Common Stock.

Our Directors, officers and employees also may solicit proxies by mail, telephone and personal contact. They will not receive any additional compensation for these activities.

As permitted by the Securities Exchange Act of 1934, as amended (the "1934 Act"), only one copy of this proxy statement is being delivered to shareholders residing at the same address, unless the shareholders have notified Cimarex of their desire to receive multiple copies of the proxy statement. This is known as "householding."

Upon oral or written request, we promptly will deliver a separate copy of the proxy statement to any shareholder residing at an address to which only one copy was mailed. Direct requests for additional copies for the current year or future years to our Corporate Secretary, Cimarex Energy Co., 1700 Lincoln Street, Suite 3700, Denver, Colorado 80203-4537, telephone (303) 295-3995 and facsimile (720) 403-9383.

Shareholders of record residing at the same address and currently receiving multiple copies of the proxy statement may contact our registrar and transfer agent, Continental Stock Transfer & Trust Company, by phone at (888) 509-5580 or by mail at 1 State Street, 30th Floor, New York, NY 10004-1561, to request a single copy be mailed in the future.

Beneficial owners should contact their broker or bank.

If you are a beneficial owner and want to vote your shares at the Meeting, you will need to ask your bank, broker or other nominee to furnish you with a legal proxy, bring the legal proxy with you to the Meeting and hand it in with a signed ballot that will be provided to you at the Meeting. You will not be able to vote your shares at the Meeting without a legal proxy. If you do not have a legal proxy, you can still attend the Meeting. We encourage you to vote your shares in advance, even if you intend to attend the Meeting. Please note that if you request a legal proxy, any previously executed proxy will be revoked, and your vote will not be counted unless you appear at the Meeting and vote in person or legally appoint another proxy to vote on your behalf.

A proposal to be acted upon at the 2019 Annual Meeting of Shareholders will be acted upon only:

•

If the proposal is to be included in the proxy statement, pursuant to Rule 14a-8 under the 1934 Act, the proposal is received by our Corporate Secretary on or before November 30, 2018, and the proposal meets the requirements of the applicable rules of the SEC and the requirements of our bylaws.



•

If the proposal is not to be included in the proxy statement, pursuant to our bylaws, the proposal is submitted in writing to our Corporate Secretary no earlier than January 10, 2019 and no later than February 11, 2019, and such proposal is, under Delaware General Corporation Law, an appropriate subject for shareholder action.



•

If the proposal concerns the nomination of Directors, see the procedures in "Election of Directors (Item 1)—Director Nominations" in the following section.

ELECTION OF DIRECTORS (ITEM 1)

Election Process

Our current Board consists of ten Directors, which is the maximum number of Directors permitted by our Certificate of Incorporation. The Board is divided into three classes: Class I, Class II and Class III Directors. At each Annual Meeting, a Class of Directors is elected for a term expiring at the Annual Meeting in the third year following the year of election. Each Director holds office until his or her successor is elected and qualifies.

The terms of the three Class I Directors, Joseph R. Albi, Lisa A. Stewart and Michael J. Sullivan, will expire at the 2018 Annual Meeting. The Nominating Committee, at its February 2018 meeting, nominated Messrs. Albi and Sullivan and Ms. Stewart for election as Class I Directors, to serve until the Annual Meeting of Shareholders to be held in 2021.

If prior to the Annual Meeting a nominee becomes unavailable to serve as a Director, any shares represented by a proxy directing a vote will be voted for the remaining nominees and for any substitute nominee(s) designated by our Board or its Nominating Committee. As of the mailing of these proxy materials, the Board knows of no reason why any Director nominee would not be available to serve as a Director.

A nominee is elected if the votes cast for his or her election exceed the votes cast against his or her election. Pursuant to our majority voting policy, each nominated Director has tendered an irrevocable resignation that is effective upon his or her failure to receive the required vote and the Board's acceptance of such resignation. If a nominee fails to receive more favorable votes than votes cast against him or her, the Nominating Committee will act on an expedited basis following the Annual Meeting to determine whether to recommend that the Board accept the Director's resignation. The Nominating Committee and the Board may consider any factors they deem relevant in deciding whether to accept the Director's resignation. The Director whose resignation is under consideration must abstain from participating in any

13

Table of Contents

decision regarding his or her resignation. The Board will publicly disclose its decision regarding acceptance of his or her resignation within 90 days after the results of the election are certified. If the resignation is not accepted, the Director will continue to serve as a Director until his or her successor is elected and qualified. If the Board accepts the resignation, then the Board will either fill the vacancy in accordance with the Bylaws or decrease the size of the Board in compliance with the Certificate of Incorporation.

Director Nominations

The Nominating Committee is responsible for identifying and evaluating potential nominees for Director and for recommending to the Board a slate of nominees for election at each Annual Meeting. Potential nominees may be suggested by Directors, members of management, shareholders or a third-party firm.

While the Nominating Committee will consider nominees recommended by shareholders, it did not receive any shareholder nominations for the 2018 Annual Meeting prior to the deadline for such nominations. Shareholders who wish to nominate persons for election as Directors at the 2019 Annual Meeting must submit a timely written notice complying with Cimarex's Bylaws to the Corporate Secretary at Cimarex Energy Co., 1700 Lincoln Street, Suite 3700, Denver, Colorado 80203-4537 or by facsimile (720) 403-9383. In addition, up to 20 shareholders collectively beneficially owning more than 3% of the Company's outstanding shares for at least three consecutive years may nominate up to two candidates for inclusion in the Company's proxy materials by following the procedures set forth in the proxy access provisions in Article III, Section 2A of our Bylaws (the "Proxy Access Policy"). To be timely, the shareholder's written notice for nominees to be considered by the Nominating Committee or proxy access candidate to be included in the proxy statement for the 2019 Annual Meeting must be received between January 10, 2019 and February 11, 2019. In addition, shareholder nominations must comply with the other requirements of Article III, Section 2 or Section 2A, as applicable, of our Bylaws.

Director Qualifications

In its assessment of each potential candidate, the Nominating Committee considers the nominee's judgment, integrity, experience, independence, understanding of Cimarex's business or related industries and such other factors that the Nominating Committee determines are pertinent in light of the needs of the Board. The Nominating Committee also considers the ability of a nominee to devote the time and effort necessary to fulfill his or her responsibilities to Cimarex. Our Nominating Committee Charter specifically includes diversity of gender and ethnic background in the list of desirable attributes sought in our Board composition.

Although all the current Directors have extensive oil and gas experience, either as company executives or attorneys, their experience is with companies with widely different operating strategies. This diversity and depth of experience benefits our Board in executing its duty of oversight and guidance.

2018 Nominees for Class I Directors

Upon the recommendation of the Nominating Committee, the Board has nominated Joseph R. Albi, Lisa A. Stewart and Michael J. Sullivan for election as Class I Directors to serve until the Annual Meeting of Shareholders to be held in 2021. The Board has determined that each of Ms. Stewart and Mr. Sullivan is independent under the New York Stock Exchange ("NYSE") corporate governance rules. Each of the Director nominees currently serves on the Board. We have no reason to believe that any of the nominees will be unable or unwilling to serve if elected.

The Board believes that the combination of the various qualifications, skills and experiences of the 2018 Director nominees will contribute to an effective and well-functioning Board. The Board also believes that, individually and as a whole, the Director nominees possess the necessary qualifications to provide effective oversight of the business and quality advice and counsel to Cimarex.

Included in each Director nominee's biography is an assessment of the specific qualifications, attributes, skills and experience of such nominee based on the qualifications described above.

DIRECTOR COMPENSATION

Our Compensation and Governance Committee administers our Director compensation program. Total Director compensation is designed to be near the 50^th percentile of that paid by comparable public oil and gas companies with similar market capitalization and revenue. We use the same group of companies in reviewing Director compensation as we use in reviewing executive base salary and total direct compensation. See "CD&A—Section 1—Competitive Positioning" for a list of, and the methodology followed in selecting, these companies. The Compensation and Governance Committee uses its independent compensation consultant, Longnecker & Associates ("Longnecker"), to review and make recommendations concerning Director compensation. The Compensation and Governance Committee, after reviewing the consultant's recommendations with the CEO and Vice President of Human Resources, recommends Director compensation for Board consideration and approval at the Board meeting held following each year's Annual Meeting of Shareholders. Payment of the annual component of Director compensation occurs on June 1 of each year. Preceding June 1, 2017, meeting fees were paid as earned. Effective June 1, 2017, meeting fees were paid quarterly.

Through May 11, 2017, compensation for non-employee Directors consisted of the following:

•

Annual cash retainer of $75,000;

•

Annual equity retainer of $180,000, comprised of restricted stock that vests in one-third increments on May 1 of each of the three years following the date of grant;

•

Committee Chairman fee of $20,000;

•

Lead Director (who also acts as Nominating Committee Chairman) fee of $40,000;

•

Board meeting attendance fee of $1,800 per meeting; and

•

Committee meeting attendance fee of $1,500 per meeting.

At the May 11, 2017 meeting, the Committee's independent consultant advised that the equity component of Director compensation was below the 50^th percentile compared to the Company's Compensation Peer Group and the total compensation for directors was at the 40^th percentile of the Company's Compensation Peer Group. (See below "CD&A—Section 1—2017 Compensation Peer Group", for a list of these companies). The cash components and value of the equity component of Director compensation had not changed since May 2014. The Board, on the recommendation of the Compensation and Governance Committee and the Compensation and Governance Committee's independent compensation consultant, and based on a study of peers and market trends, made the following change to the compensation program for non-employee Directors:

•

Increased the annual equity retainer to $200,000, comprised of restricted stock that vests on the earlier of (i) the termination of the service as a Director other than because of removal or (ii) May 1, 2018.

The other components of non-employee Director compensation did not change. Following this change, the total Director compensation was between the 50^th and 75^th percentiles of the Company's Compensation Peer Group.

Table of Contents

The following table discloses as of December 31, 2017 the aggregate number of outstanding unvested stock awards and the market value of those awards. Market value is based on the closing trading price of $122.01 on December 29, 2017, which was the last trading day of 2017. The Directors have the right to vote and receive dividends on unvested stock awards. There were no outstanding vested but unexercised option awards as of that date.

Our Corporate Governance Guidelines require that each independent Director own Cimarex stock in an amount equal to three times his or her annual cash retainer. A newly elected Director has three years from the date of his or her initial election to comply with the Corporate Governance Guidelines. Restricted stock, restricted stock units and deferred compensation units are counted in calculating ownership; shares subject to options are not counted. Each of the independent Directors complies with these guidelines.

In connection with his retirement from the Board effective immediately following the annual meeting on May 11, 2017, the Board appointed Mr. Teague as Director Emeritus for up to a two-year term. As compensation for serving as Director Emeritus, all outstanding restricted stock awards held by Mr. Teague at the time of the expiration of his term as Director continue to vest according to their terms during the period he serves as Director Emeritus. Mr. Teague will not receive any additional stock awards as Director Emeritus. Mr. Teague will be entitled to a cash retainer of $85,000 per year. The Company entered into an indemnification agreement with Mr. Teague with substantially the same terms as his indemnification agreement as a Director.

BOARD AND COMMITTEE INFORMATION

Our Board

During 2017, the Board of Directors met seven times. The Board has three Committees: the Audit Committee, the Compensation and Governance Committee, and the Nominating Committee. During 2017, each Director attended greater than 75% of the meetings of the Board and the Board Committees on which he or she served. All Board members are expected to attend the Annual Meeting. All Directors attended our 2017 Annual Meeting.

Board Leadership Structure

Cimarex has a combined Chairman of the Board and CEO. Cimarex also has a Lead Director who is chosen annually from our independent Directors. Following is a summary of the functions of the Chairman of the Board/CEO and the Lead Director, as provided in our Lead Director Charter:

23

---

Table of Contents

The Board believes that the roles of a combined Chairman/CEO and an independent Lead Director having the duties described above serve the interests of our shareholders because this structure provides an appropriate balance between strategy development and independent oversight of management.

Thomas Jorden was elected Chief Executive Officer on September 30, 2011 and Chairman of the Board on August 14, 2012. He has served as an executive officer of Cimarex since its formation in 2002. He has considerable knowledge and experience gained through his executive positions with Cimarex and prior industry experience. This knowledge and experience allow him to focus the activities of the Board on matters most relevant to the success of Cimarex.

Our Board structure is designed to avoid any undue influence by the Chairman of the Board/CEO on the Board. The Compensation and Governance Committee is comprised entirely of independent Directors. When the Board acts on the Compensation and Governance Committee's recommendation for compensation of the Chairman/CEO, it acts without him being present.

The substantial experience and background of our independent Directors ensure their active and knowledgeable involvement in Board matters. This involvement, and the presence and involvement of our Lead Director, provide the Board with a strong and independent point of view.

Board Committees

Director Independence and Related Person Transactions

Our Corporate Governance Guidelines require that a majority of our Board of Directors be independent as defined by applicable laws, rules, regulations and listing standards. We comply with the criteria for independence established by the NYSE listing requirements and other governing laws and regulations.

Each year the Compensation and Governance Committee reviews the independence of our Directors and any related person transactions. On the basis of this review, the Committee delivers a report to the Board of Directors, and the Board makes independence determinations based on the Committee's report.

As a result of this review, the Board has determined that Hans Helmerich, David A. Hentschel, Harold R. Logan, Jr., Floyd R. Price, Monroe W. Robertson, Lisa A. Stewart, Michael J. Sullivan and Frances M. Vallejo, representing eight of our ten current Directors, are independent of Cimarex and its management. Thomas Jorden and Joseph Albi are not independent because of their employment as CEO and COO of Cimarex, respectively.

In making these determinations, the Board considered that, in the ordinary course of business, relationships and transactions may occur between Cimarex and entities with which some of our Directors are or have been affiliated. As a result of the Committee's review, certain relationships and transactions are not considered to be material transactions that would impair a Director's independence, including the following:

•

The Director is an employee of another company that does business with Cimarex, and our annual sales to or purchases from the other company amount to less than 2% of the annual revenues of the other company and that such sales to or purchases from the other company are part of our ordinary course of business and conducted in the same manner as we obtain services from other companies that provide similar services; or



•

The Director is a director (but not an employee) of another company that does business with Cimarex.

Hans Helmerich is the non-executive Chairman of the Board, and until March 5, 2014 was the CEO, of Helmerich & Payne, Inc. ("H&P"), a company with which Cimarex engages in ordinary course of business transactions. As non-executive Chairman, Mr. Helmerich currently is not an employee of H&P. During H&P's fiscal year ended September 30, 2017, Cimarex paid H&P $39.6 million for drilling services in arms' length transactions and as part of our ordinary course of business and in the same manner as we obtain services from other companies that provide similar services. The aggregate amount of the payment represented 2.20% of H&P's revenue during that period. The Compensation and Governance Committee reviewed these transactions and concluded: (i) the transactions are proper and not material when compared to both Cimarex's total drilling costs and H&P's total revenues; (ii) the transactions occur in the ordinary course of business and at arms' length; (iii) the Board does not review or approve drilling service contracts or arrangements; and (iv) Mr. Helmerich's relationship with H&P does not interfere with his independent judgment as a Director of Cimarex.

Ms. Stewart is Chairman, President, Chief Executive Officer and Chief Investment Officer of Sheridan Production Partners, a privately—owned oil and gas operating company she founded in 2007. During 2017 Cimarex paid certain affiliated companies of Sheridan oil and gas revenues of $208 thousand and received $89 thousand from certain affiliates of Sheridan for joint interest billings. The payments to the affiliates of Sheridan represented 0.03% of Sheridan's consolidated revenues for 2017. In addition, Cimarex paid the Sheridan affiliates joint interest billings of $1 thousand, and received $378 of oil and gas revenues. The Compensation and Governance Committee reviewed these transactions and concluded: (i) the transactions are proper and not material when compared to both Cimarex's total costs and Sheridan's revenues; (ii) the transactions occur in the ordinary course of business and at arms' length; (iii) the Board does not review or approve oil and gas revenue payments or joint interest billings; and (iv) Ms. Stewart's relationship with Sheridan does not interfere with her independent judgment as a Director of Cimarex.

Risk Oversight

The Board has overall responsibility for risk oversight. In carrying out its responsibility, the Board has requested that the Audit Committee discuss with management and report to the Board with respect to:

•

Processes Cimarex follows to mitigate corporate risks;

•

Guidelines and processes pertaining to financial risk assessment;

•

Steps management takes to measure, monitor and control financial risk exposures; and

•

Management's conclusion as to the effectiveness of the guidelines and processes utilized to mitigate such corporate and financial risks and exposures.

In addition, at each of the Board's four regularly scheduled meetings held during the year, management provides the Board with an overview of Cimarex's operations, financial results, risks and risk mitigation efforts, and other aspects of its business. Significant strategic considerations, such as material acquisitions or mergers are brought to the Board for deliberation and, as appropriate, decisions.

The Audit Committee, at its December 7, 2017 meeting, reviewed, discussed and, at the Board meeting that day, reported to the Board about corporate, operational and financial risks and Cimarex's processes for mitigation of these risks.

Compensation Risk Oversight

In February 2018, the Compensation and Governance Committee performed a thorough review of the possible connection between compensation and excessive risk taking. The Compensation and Governance Committee's review covered Cimarex's compensation policies and practices covering executive and non-executive employees to determine whether the policies and practices encourage excessive risk taking by employees. The Committee's analysis included a review and discussion of the following:

•

The metrics for determining incentive awards;

•

Participants in the Company's compensation programs;

•

How the compensation pools and individual awards are determined;

•

The maximum individual award potential (maximum individual incentive to take risk);

•

The maximum possible cost if awards were paid at maximum levels (maximum cost exposure);

•

The decision-making and approval process; and

•

The systemic limitations on the ability to take excessive risks in order to influence compensation.

The Compensation and Governance Committee determined that the risks from Cimarex's compensation policies and practices for Cimarex employees are not reasonably likely to have a material adverse effect on Cimarex.

Executive Sessions

The independent Directors meet in executive session at each regularly scheduled Board meeting. The Lead Director presides over executive sessions. During 2017, four executive sessions were held and all of the independent Directors attended each session with the exception of Mr. Logan, who missed one meeting. These sessions allow independent Directors to review the CEO's performance and compensation, to discuss issues of importance to Cimarex, including the business and affairs of Cimarex, as well as matters concerning management, without any member of management present.

Shareholder Engagement

Cimarex's relationships with its shareholders are an important part of our corporate governance profile, and we recognize the value of taking their views into account. Engagement with shareholders helps us understand the larger context and impact of our operations, learn about expectations for our performance, assess emerging issues that may affect our business or other aspects of our operations, and shape corporate and governance policies.

Table of Contents

Consistent with our commitment to seek and respond to shareholder input on corporate governance topics, we have considered and discussed with investors a wide variety of matters, including:

Our executive compensation program and disclosures, as a result of which we previously made changes in these areas;

•

The "proxy access" shareholder proposal acted upon in 2015;

•

A shareholder proposal concerning fugitive methane reporting that was made in December 2015 and subsequently withdrawn, as a result of which we added disclosure concerning methane emissions to our website; and

Executive Summary of Compensation Discussion & Analysis ("CD&A")

2017 BUSINESS AND FINANCIAL PERFORMANCE OVERVIEW

The great volatility in the oil and gas exploration and production industry in 2016 transitioned to more stability in commodity prices in 2017. The Compensation and Governance Committee continued to focus on strategic and tactical goals that preserve Cimarex's strong balance sheet, core properties and organization while improving health, safety and environment metrics. These goals and our performance are summarized below under "Section 2—Annual Cash Incentive Awards". As the year progressed, oil and natural gas liquids ("NGL") prices stabilized at higher levels than 2016. It is through this macroeconomic lens that the Committee considered the following 2017 business and financial performance overview when making compensation decisions:

•

Exploration and development expenditures increased 74% to $1,281.1 million compared to $734.8 million in 2016, while year-over-year average daily production increased 19% to 1,142.1 MMcfe per day.

•

While total production expense increased by approximately $30.2 million, or 13%, from $232.0 million in 2016 to $262.2 million in 2017, our Operations group excelled at optimizing our production. As a result, our production expense per Mcfe declined almost 5% from $0.66 per Mcfe in 2016 to $0.63 per Mcfe in 2017, and declined 42% in 2017 compared to 2014.

•

We incurred no additional debt and had cash on hand of $400.5 million at year-end 2017.

•

Year-over-year production revenues increased 53% to $1.9 billion as revenues were positively affected by increased realized commodity prices as well as increased production, which resulted in net income of $494.3 million in 2017 after losses in each of 2016 and 2015.

•

Cash flow provided by operating activities of $1.1 billion was 75% higher than 2016.

•

During 2017, our overall estimated proved reserves increased 16% after additions, positive and negative revisions, and production. We added 940.7 Bcfe of proved reserves through extensions and discoveries, in the Mid-Continent and Permian Basin, where we added 282.9 Bcfe and 657.8 Bcfe, respectively. In addition, we had net negative revisions of previous estimates of 59.7 Bcfe. Revisions were comprised of an increase of 45.8 Bcfe for net positive performance revisions, a decrease of 43.9 Bcfe related to higher operating expenses, an increase of 187.2 Bcfe for positive revisions due to higher commodity prices, and a decrease of 248.8 Bcfe for the removal of proved undeveloped reserves, the development of which likely will be delayed beyond five years from our initial disclosure.

•

As a result of our strong financial and operation performance in 2017, we continued to outperform our peers in a difficult macro-economic energy environment. Our relative three-year stock price performance as compared to our peer group performed at the 78^th percentile.

2017 EXECUTIVE COMPENSATION

Table of Contents

ELEMENTS AND MIX OF EXECUTIVE COMPENSATION

Principal Elements of Executive Compensation

We principally use three elements of executive compensation to carry out the design of our executive compensation program, collectively referred to as "Total Direct Compensation":

Mix of Executive Compensation

Cimarex's executive compensation program directly links a substantial portion of executive compensation to Cimarex's performance through annual and long-term incentives. The diagrams below show the mix of the pay elements for the CEO and other NEOs for fiscal 2017. These diagrams are based on the Summary Compensation Table and highlight the substantial portion of the at-risk compensation that only is realized if certain performance criteria are met. Of the CEO's total disclosed 2017 compensation, 90% is at risk and is linked to Cimarex's future performance. This consists of 18% annual cash incentive compensation based on 2017 performance and 72% long-term equity incentive compensation that is both service- and performance-based. The 2017 average compensation mix for the other NEOs was 88% at risk compensation consisting of 19% annual cash incentive compensation based on 2017 performance and 69% long-term equity incentive compensation that is both service- and performance-based.

COMPENSATION DISCUSSION AND ANALYSIS

This CD&A describes Cimarex's executive compensation program for 2017. We use this program to retain, motivate and attract (when appropriate) the executives who lead our business. This CD&A explains how the Compensation and Governance Committee (the "Committee") of the Board of Directors made 2017 compensation decisions for our executives, including the following NEOs:

•

Thomas E. Jorden, Chairman of the Board, CEO and President (Principal Executive Officer)

•

G. Mark Burford, Vice President and CFO (Principal Financial Officer)

•

Joseph R. Albi, Executive Vice President—Operations, COO

•

Stephen P. Bell, Executive Vice President—Business Development

•

John A. Lambuth, Senior Vice President—Exploration

This CD&A is divided into three sections:

Section 1 discusses our compensation framework, principal elements of executive compensation, and competitive positioning.

Section 2 discusses 2017 and early 2018 actions related to 2017 executive compensation.

Section 3 discusses the role of the Committee's independent compensation consultant and management in compensation decisions, post-employment compensation, retirement benefits, perquisites and other compensation related issues.

SECTION 1

Our Compensation Framework

Objectives

Our principal business objective is to profitably grow our proved oil and gas reserves and production for the long-term benefit of shareholders while seeking to minimize our impact on the communities in which we operate for the long-term. The primary strategy we use to achieve this objective is to reinvest our cash flow from operations at a competitive rate of return. Our executive compensation program is designed to retain, motivate and attract, when appropriate, the experienced professionals necessary to carry out this strategy.

Throughout the Company, we focus on attracting high quality personnel who have strong technical competence, are not afraid to contribute new ideas, and work well in a team environment. The Company recently undertook a study of compensation across all areas and disciplines within Cimarex. The data confirmed no compensation bias at Cimarex, and every employee is paid equitably for their position regardless of gender, ethnicity or age. This study will be reviewed periodically to ensure these results remain consistent.

The Committee also engaged our independent compensation consultant, Longnecker & Associates ("Longnecker"), to analyze the actual delivery of compensation versus the performance of the Company as compared to the Compensation Peer Group (see below, "—2017 Compensation Peer Group," for a list of these companies). Longnecker concluded that Cimarex had the highest correlation of realized pay to performance out of all the Compensation Peer Group companies.

Design

We design our executive compensation program to:

•

Align performance incentives with the long-term interests of our shareholders.  

We align the long-term interests of our executives with the long-term interests of our shareholders by paying a substantial portion of each executive's total direct compensation in the form of performance-based equity awards. The vesting of up to half of the NEOs' equity awards is dependent upon relative stock price performance, meaning the more our shareholders benefit through shareholder returns compared to a defined stock performance peer group, the more our executives benefit through increased vesting of performance-based equity awards. Also, our Executive Stock Ownership Guidelines encourage executives to have a meaningful ownership stake in Cimarex, further aligning the interests of our shareholders and our executives.

•

Provide competitive total direct compensation opportunities that retain, motivate and attract, when needed, executive talent.

We compensate our executives at levels that are competitive with equivalent positions at companies with which we may compete for talent as represented by our Compensation Peer Group (See "2017 Compensation Peer Group" below). In general, when we review base salaries, annual incentive awards, long-term equity awards and total direct compensation, we reference the 50th and 75th percentiles of the Compensation Peer Group. Actual compensation earned by an executive may be outside this range based on the Company's performance, the individual's achievements, and industry competition for talented executives. Half of our restricted stock awards vest based on continued employment and the passage of time, which promotes retention of executives.

•

Link compensation earned to achievement of short-term and long-term financial and operational objectives.

We provide the opportunity for an annual incentive cash award that is designed to reward executive efforts for achieving Company financial and operational objectives. The portion of our long-term equity incentive awards that vest based on performance measures tied to relative stock price performance are designed to encourage above average stock price performance, which aligns executives' interests with shareholders' interests.

Principal Elements of Executive Compensation

We principally use three elements of executive compensation to carry out the design of our executive compensation program, collectively referred to as "Total Direct Compensation":

Table of Contents

Competitive Positioning

In support of our compensation objectives and in order to determine an appropriate total value and mix of pay for executives, we reference the 50th and 75th percentiles of the Compensation Peer Group. The 50th and 75th percentiles are reference points only; we do not automatically compensate each executive at these levels. Several variables, including individual and division performance, time employed in the position, annual Company performance and one- and three-year relative stock price performance influence the actual executive compensation decisions. We look at our individual NEO and total NEO Total Direct Compensation compared to individual NEO and total NEO Total Direct Compensation of companies in our Compensation Peer Group. Because not all of our NEO positions are directly comparable to NEO positions of companies in our Compensation Peer Group, we believe that reviewing the aggregate Total Direct Compensation of all NEOs provides an appropriate reference for comparative purposes and allows us to compare our total cost of management for all NEOs to our peers' total cost of management.

2017 Compensation Peer Group

The Compensation Peer Group is comprised of companies in the oil and gas industry with market capitalizations and revenues similar to ours and with whom we compete for executive and other employee talent. The Committee annually reviews companies in the Compensation Peer Group and modifies the group as appropriate.

In May 2017, the Committee approved the 2017 Compensation Peer Group. The companies included in the Compensation Peer Group were, at the time of selection, comparable to Cimarex in size and scope of operations, market capitalization and revenue. These are companies with whom we believe we compete for employees. The April 28, 2017 market capitalization of these companies ranged from $3.7 billion to $20.9 billion and the trailing 12 months' revenue, as of the previous quarterly report on Form 10-Q filed by these companies, ranged from $527 million to $5.4 billion. For the comparable date and period, Cimarex's market capitalization was $11.1 billion and its revenue was $1.3 billion. The Committee's independent compensation consultant recommended removing one company that was in the 2016 Compensation Peer Group due to its smaller size compared to other members of the peer group. This company was QEP Resources, Inc., which had a market capitalization of $2.7 billion and trailing 12 month revenues of $1.4 billion. The consultant also recommended adding two new companies, Diamondback Energy, Inc. ("Diamondback") and Apache Corporation ("Apache"). The consultant recommended Diamondback because its financial metrics closely aligned with those of Cimarex, and its operations are concentrated in the Permian Basin, where Cimarex has substantial operations. The consultant recommended Apache because of its market capitalization and increasing operational focus in the Permian Basin. Diamondback had a market capitalization of $9.8 billion and trailing 12 month revenues of $527 million. Apache had a market capitalization of $18.5 billion and trailing 12 month revenues of $5.4 billion. The Committee approved these recommendations, resulting in the inclusion of the following companies in the 2017 Compensation Peer Group:

2017 Stock Performance Peer Group

Under our long-term equity incentive award program, we grant performance-based awards of restricted stock to our NEOs. For grants made in December 2017, the performance measure used to determine the number of shares to be delivered upon vesting is Cimarex's relative stock price performance at the end of the three-year period preceding the December 1, 2020 vesting date when compared to companies in the S&P 500 Oil and Gas Exploration & Production index (the "Stock Performance Peer Group"). The Stock Performance Peer Group members are companies with which we compete for investors and investment capital. The Committee believes that using an index of companies selected by an independent group such as Standard and Poor's provides less ability for management to attempt to manipulate

relative performance. The following are the companies that comprised the Stock Performance Peer Group on December 7, 2017:

See "Key 2017 Compensation Actions" below for more detail.

Response to 2017 Say-on-Pay Vote and Shareholder Engagement

At the 2017 Annual Meeting of Shareholders, 97% of the votes cast were in favor of the advisory vote to approve executive compensation. Also, 84% of shares voted in favor of holding the say-on-pay vote on an annual basis, which the Board approved during the August 31, 2017 Board meeting. In addition to the advisory vote, as part of our regular shareholder engagement, we consider and discuss with shareholders a number of matters throughout the year,

including executive compensation and environmental, social and governance ("ESG") issues. The Committee carefully considers any feedback and routinely reviews executive compensation practices and ESG issues.

The Committee considered the results of the advisory vote and the discussions with shareholders to convey our shareholders' support of the Committee's compensation decisions in 2016 and early 2017 and shareholders' overall satisfaction with Cimarex's executive compensation programs. Consistent with this support, the Committee retained the core design of our executive compensation programs for the remainder of 2017.

Key 2017 Compensation Actions

The following discusses the Committee's key 2017 compensation decisions, which are reflected in the 2017 Summary Compensation Table below. These decisions were made with the advice and concurrence of the Committee's independent consultant, Longnecker & Associates. (See "CD&A—Section 3" for additional discussion regarding the role of the consultant.)

CEO Compensation

•

Mr. Jorden's annual salary for 2017 remained $960,000 for the reasons described below.



•

Mr. Jorden's 2017 annual cash incentive award was $2,000,000, or 208% of his year-end base salary. His target annual cash incentive award is 125% of his year-end base salary and his maximum award is 250%.



•

Mr. Jorden's annual long-term incentive equity award value at the date of grant (December 7, 2017) was $8,000,000.

These decisions were reviewed in detail by the Committee and its independent consultant. The Committee considered several factors, including input from its independent consultant, compensation data from peer companies and Cimarex's performance. In 2017, approximately 90% of Mr. Jorden's compensation as disclosed in the Summary Compensation Table was at risk.

Other NEO Compensation

The Committee also made compensation decisions for the other NEOs comprised of base salary adjustments made in May 2017, annual cash incentive awards for 2017 made in February 2018, and long-term equity awards made in December 2017. These adjustments were based upon the recommendations of the CEO, evaluation by the Committee, the advice and recommendations of the Committee's independent consultant, salary data from peer and broader market surveys, internal pay relationships based on relative duties and responsibilities, the executive's impact on Cimarex's results, and for retention purposes. Based upon these considerations, the Committee made the following 2017 NEO compensation decisions:

Base Salary Determination

We provide competitive base salaries to retain and attract, when appropriate, talented executives and to provide a fixed base of cash compensation. We compare each Cimarex NEO's base salary with the base salary paid for a similar executive position by companies in our Compensation Peer Group. See "Competitive Positioning" above in this CD&A for a list of the companies in the Compensation Peer Group. The Committee then may adjust base salaries based on a number of factors, including job responsibilities, management experience, individual contributions, number of years in position and current salary.

In May 2017, the Committee's independent compensation consultant reviewed the NEOs' base salaries compared to Compensation Peer Group data and broader market data and initially recommended a 3% increase in executive salaries for each NEO. The compensation consultant noted that each NEO's salary was between the 50^th and 75^th percentiles of the Compensation Peer Group. Mr. Jorden, our CEO, provided the Committee with recommendations for NEOs other than himself. While Mr. Jorden, our CEO, typically does not make recommendations concerning his own salary, in May 2017 he recommended that he and Mr. Burford, the CFO, not receive salary increases for 2017. This recommendation was due to corrections made to Cimarex's financial statements resulting from errors in the quarterly ceiling test calculations used to test for possible impairments of Cimarex's oil and gas properties. For a complete description of these corrections, see the "Explanatory Note" to Cimarex's amended Annual Report on Form 10-K/A for the year ended December 31, 2016 filed with the SEC on May 10, 2017. With respect to the other NEOs, Mr. Jorden's recommendations were based on maintaining alignment of the NEOs between the 50^th and 75^th percentile of the Compensation Peer Group and Company relative TSR performance being in the 63^rd percentile of the Compensation Peer Group companies for the previous one-year period and the 79^th percentile among those companies for the previous three-year period. The Committee considered the recommendations of both the Committee's consultant and Mr. Jorden for NEOs other than Mr. Jorden. With respect to Mr. Jorden's salary, in discussions in executive session with the compensation consultant and without Mr. Jorden present, the Committee considered Mr. Jorden's leadership of Cimarex through a reduced commodity price environment, including Cimarex's relative TSR performance in the 63^rd percentile compared to the Compensation Peer Group for the past one year and in the 79^th percentile for the past three years, and his salary being between the 50^th and 75^th percentiles of the Compensation Peer Group's CEO salaries. However, due to the financial statement corrections described above, the Committee determined not to adjust the salaries of Mr. Jorden and Mr. Burford. The Committee also reviewed the total salaries and recommended salaries of all the NEOs compared to the total salaries of the NEOs of the Compensation Peer Group. Before the recommended salary increases, aggregate NEO salaries were at the 61^st percentile of the Compensation Peer Group. The recommended increases put the NEOs at the 66^th percentile. The compensation consultant indicated its concurrence with the Committee's recommendations based on these reasons and the compensation consultant's experience with, and knowledge of, compensation decisions of other oil and gas exploration and production companies. The Committee recommended, and the Board approved, the following base salaries effective June 1, 2017:

Annual Cash Incentive Awards

In February 2018, the Committee met to deliberate and determine NEO (including the CEO) annual cash incentive awards for 2017 performance. The individual target for the CEO is 125% of his base salary and for each other NEO is 100% of his base salary. There is no minimum award, and an individual's maximum award is 250% of base salary for the CEO and 200% of each other NEO's base salary.

In February 2017, the Compensation and Governance Committee adopted 2017 strategic and tactical goals and objectives to be measured in 2018. At the time the Committee approved these goals, commodity prices had recently increased but were still very volatile, with oil near $50 per barrel, and the Committee continued its focus from 2016 on goals that preserve Cimarex's strong balance sheet, core properties and organization during a difficult period for the oil and gas industry. The table below explains the level of achievement of the 2017 strategic and tactical goals and objectives.

Table of Contents

The Committee's independent compensation consultant recommended a pool for cash incentive awards for all NEOs of $5.8 million or 192% of the NEOs' year-end 2017 salaries, based on the consultant's review of the Company's achievement of the 2017 strategic and tactical goals, the consultant's analysis of the projected annual incentive awards of the Compensation Peer Group to be generally at target levels or slightly above target level for 2017 performance, the consultant's evaluation of the Company's performance of its 2017 strategic and tactical goals compared to the Compensation Peer Group's percentile rankings, and the consultant's review of actions by other oil and gas exploration and production companies related to annual incentive awards due to commodity price and stock price trends. Based principally on the achievement of the 2017 strategic and tactical goals and objectives and the improvement in and stabilizing of commodity prices and expected improvement in the Company's cash flow, the CEO recommended cash incentive awards for the other NEOs of between 164% and 177% of their year-end 2017 salaries, which were slightly lower than the recommendations of the Committee's independent compensation consultant. The Committee's independent consultant concurred that the CEO's recommendations were reasonable. The Committee, after considering the achievement of the 2017 strategic and tactical goals and objectives, the improvement in and stabilizing of oil and gas prices and the impact on cash flow, and in consultation with its independent consultant, accepted the CEO's recommendations, and the Board approved the Committee's recommendations.

The Committee, with its independent consultant, and without management present, deliberated concerning the CEO's annual cash incentive award. Based on its analysis of the Company's 2017 performance described above and the CEO's leadership of the Company and management of senior executives and other employees to achieve this performance, the Committee recommended and the Board approved a cash incentive award to the CEO of 208% of his base salary, which was approximately 6% below the recommendation of the Committee's independent compensation consultant. The Committee's independent consultant concurred with this recommendation, and the total cash incentive awards to all NEOs of $5.51 million was $0.3 million below the recommendation of the compensation consultant of a reasonable pool of $5.8 million. Following are the CEO and other NEO 2017 annual cash incentive awards:

Long-Term Equity Incentive Award Program

Our long-term equity incentive award program balances the short-term annual cash incentive program by focusing executive efforts on the activities that lead to long-term shareholder value. Typically, the Committee grants equity awards of restricted stock to NEOs each year.

For grants made in December 2017, the number of shares that NEOs may earn is determined by the relative stock price performance of Cimarex when compared to the Stock Performance Peer Group. See "CD&A—Competitive Positioning" for a list of the companies in the 2017 Stock Performance Peer Group. The awards vest on December 1, 2020, based on the Company's relative stock price performance compared to the Stock Performance Peer Group for the three years ending December 1, 2020, and are subject to a continuous service requirement. A minimum of 50% of the shares granted and a maximum of 100% of the shares granted may be earned at the end of the three-year performance period. Half of our restricted stock awards vest based on continuous employment and the passage of time, which promotes retention of executives, and the other half of the awards vest based on performance measures tied to relative stock price performance, which promotes the long-term interests of our shareholders and aligns executives' interests with shareholders' interests. While the 2014 Equity Incentive Plan does not set a minimum vesting period, the Committee has set a three-year vesting period for restricted stock awards to NEOs since the Committee began making restricted stock awards in 2006.

Dividends equivalent to those paid on Cimarex common stock are paid on the shares awarded that are subject to time-based vesting, and dividends applicable to the remainder of the shares awarded are accrued and only paid on the

43

Table of Contents

shares earned following calculation of Cimarex's relative stock price performance compared to companies in the Stock Performance Peer Group at the end of the performance period. All of the shares subject to the award have the same voting rights as outstanding shares of Cimarex common stock.

For restricted stock awards made in December 2017, the total number of shares earned is determined by calculating the percentage difference between the average per share closing price for shares of Cimarex and each company in the Stock Performance Peer Group for the 30 trading days preceding December 1, 2017 and the 30 trading days preceding December 1, 2020. The Committee ranks Cimarex and calculates its relative performance percentile. Companies that are not in the Stock Performance Peer Group at both the beginning and the end of the performance period are not included in the calculation. Companies that declare bankruptcy or are delisted and cease to be traded on a national securities exchange are ranked last at the end of the performance period. The following table illustrates shares that would be earned at various relative stock price performance percentiles (assuming 17 companies in the Peer Group).

On December 7, 2017, the Committee granted long-term equity awards to the NEOs with a total grant date fair value of $20,850,000 based on competitive market data for companies in Cimarex's Compensation Peer Group. Comparative data was obtained by the Committee's independent consultant from public filings disclosing 2017 NEO compensation of companies in the Compensation Peer Group and the consultant's knowledge of other companies for which the consultant provides services. See "CD&A—Competitive Positioning" for a list of the companies in the Compensation Peer Group.

The Committee's compensation consultant recommended awards with a value between the 75^th percentile and 90^th percentile when compared to companies in the Compensation Peer Group. The factors considered by the consultant in making its recommendations included the following:

•

Cimarex was the third-highest performing company in the Compensation Peer Group when comparing current stock price to the respective historical all-time high price. This is indicative of Cimarex's historical performance through industry cycles including the prolonged oil price decline beginning in late 2014.

•

Cimarex was the third-highest performer in the Compensation Peer Group based on three-year relative TSR performance.

•

Due to Cimarex's better relative stock price performance during the industry downturn compared to peers, the Company faces a potential disadvantage in the NEOs' ability to earn payouts based on relative stock price performance going forward.

•

The tenure of executives in their respective roles has increased and they achieved good overall performance.

The Committee approved awards within the recommended total pool range based on Cimarex's TSR compared to its Compensation Peer Group for the periods indicated, the total direct compensation of our NEOs compared to that of our peer companies, Cimarex's 2017 financial and operational performance, and the compensation consultant's recommendations. The Committee's consultant concurred with the Committee's final determination. The actual value of the awards upon vesting in December 2020 will be based on Cimarex's relative three-year stock price performance compared to the other companies in the Stock Performance Peer Group as described above and Cimarex's stock price at that time.

The Committee granted a total of 233,065 restricted shares to the NEOs (including the CEO). The number of shares granted to each NEO was based on their relative individual roles and responsibilities. Of the total number of shares granted to the NEOs (including the CEO), the Committee awarded 38% of the shares to Mr. Jorden, 16% of the total shares to Mr. Albi, 16% to Mr. Lambuth, 15% to Mr. Bell and 14% to Mr. Burford. The following table reflects the awards made by the Committee:

2017 Vesting of NEO Equity Awards

On December 10, 2017, the performance period applicable to the December 10, 2014 NEO equity awards ended. Cimarex's relative stock price performance was in the 94^th percentile of the Stock Performance Peer Group at the end of the performance period, resulting in the vesting of 100% of the shares subject to the December 10, 2014 award.

The following table reflects the shares originally granted to each NEO in 2014 and the number of shares that vested at the end of the three-year performance period:

During 2017, restricted share awards granted to Mr. Lambuth and Mr. Burford in 2012, prior to their becoming NEOs, vested. The restricted shares that vested in 2017 are included below in "Compensation Tables—2017 Option Exercises and Restricted Stock Vested."

Mr. Burford did not receive a performance share award in 2014 because he was not CFO at that time.

The vesting of these awards and the value at vesting is also reported in "2017 Option Exercises and Restricted Stock Vested" table in this proxy statement. For a comparison of the grant date fair value of the performance shares granted in December 2014 to the value realized upon vesting in December 2017, see footnote 1 to that table.

Elimination of Tax Gross Up Payments

In March 2013, the Board amended Cimarex's Change in Control Severance Plan to eliminate any participant's right (including the right of any NEO) to a tax gross-up payment.

Cimarex's Change in Control Severance Plan is the only plan that provided for a tax gross-up payment to a participant following a change in control if any payments received by the participant as a result of the change in control become subject to the excise tax imposed by Section 4999 of the Internal Revenue Code. See "Potential Payments Upon Change in Control or Termination" for a more detailed description of this Plan.

achievement. The specific numerical levels will be discussed in the Compensation Discussion and Analysis concerning 2018 compensation decisions contained in the proxy statement for the 2019 Annual Meeting of Shareholders.

The strategic and tactical measures and objectives have been clearly communicated to the NEOs. At year end, the CEO will deliver a report of results to the Committee with respect to each goal and provide the CEO's recommendation and the basis for the CEO's recommendations for individual awards. The Committee and its independent compensation consultant will review the CEO's recommendations and accept or modify those recommendations. The non-management members of the Board will consider the recommendations of the Committee. Each NEO, other than the CEO, has a threshold award of 0% of year-end base salary (no minimum award), a target award equal to 100% of year-end base salary, and a maximum award of 200% of year-end base salary. The CEO has a threshold award of 0% of year-end base salary, a target award equal to 125% of year-end base salary, and a maximum award of 250% of year-end base salary.

SECTION 3

Role of Compensation Consultant and Management in Compensation Decisions

Compensation Consultant

The Committee has engaged the firm of Longnecker & Associates ("Longnecker") as its independent compensation consultant to fulfill the following responsibilities:

•

Advise the Committee on management proposals, as requested;

•

Undertake special projects at the request of the Committee;

•

Participate in Committee meetings;

•

Make recommendations concerning the Compensation Peer Group;

•

Review the selected Peer Group and survey data for competitive comparisons;

•

Provide market data and recommendations on NEO compensation; and

•

Provide market data and recommendations on non-employee Director compensation.

The Committee has considered the independence factors adopted by the NYSE and has determined that its consultant, Longnecker, is independent within the meaning of the NYSE listing standards.

As part of its ongoing services to the Committee, one or more representatives of Longnecker attended six of the Committee meetings held in 2017. Longnecker provided the following services in 2017:

•

Reviewed and provided input on the CD&A in the 2017 proxy statement;

•

Attended the February 23, 2017 Compensation and Governance Committee meeting and consulted with the Committee on annual cash incentive awards;

•

Attended the May 11, 2017 Compensation and Governance Committee meeting and consulted with the Committee on executive base salary levels;

•

Made recommendations concerning the Compensation Peer Group;

•

Conducted a market analysis of Board compensation and consulted with the Committee concerning Board compensation; and

•

Provided an executive compensation analysis and a recommended range for long-term equity grants and participated in the December 7, 2017 Compensation and Governance Committee meeting and consulted with the Committee on performance share awards.

Management

Our CEO and President is the principal management resource for compensation recommendations to the Committee with respect to the other NEOs. The CEO (i) provides an annual assessment of Cimarex's overall financial and operational performance and (ii) subjectively evaluates individual NEO performance and recommends individual base salary adjustments, annual cash incentive awards, and long-term equity awards. His subjective evaluations generally include factors such as scope of responsibility, contribution to Company performance, technical competence, managerial

Table of Contents

skills and advancement potential. The Committee considers the CEO's recommendations in making decisions regarding executive compensation. The Committee exercises its discretion to accept, reject or modify these compensation recommendations.

Our Vice President—Human Resources, Government Relations, and External Affairs acts as an informational resource to Longnecker and the Committee and compiles survey and other compensation data for their review. The Committee, in consultation with Longnecker, reviews this information when making executive compensation and program design decisions.

Other Compensation Arrangements

Post-Employment and Employment Arrangements

All employees, including the NEOs, are covered by the Cimarex Change in Control Severance Plan. The Plan provides for a "double trigger" so that payments are made only if (a) there is a change in control (as defined in the Plan) and (b) an employee is terminated for any reason other than "cause" (as defined in the Plan) within two years following a change in control. In the event that both of the above contingencies are satisfied, the employee is entitled to (i) cash severance payments of two times annual salary and average cash incentive award, (ii) a pro-rata portion of annual cash incentive bonus for the current year, and (iii) continued medical, dental, disability and life insurance benefits for two years. See "Potential Payments Upon Change in Control or Termination" for a more detailed description of these benefits. In addition, the 2014 Equity Incentive Plan and the terms of employee equity award agreements provide for acceleration of vesting of outstanding equity awards upon the occurrence of a change in control.

Cimarex assumed the change in control provisions from the now-expired employment agreements between each of Messrs. Albi, Bell, and Jorden and a predecessor company. The assumed portion of each agreement provides that if the executive is terminated without cause within two years following a change in control event (as defined in the agreement), the executive is entitled to a lump-sum payment equal to two times the executive's base salary at the time of the change in control. Benefits payable under these agreements are forfeited if the executive receives benefits under any other change in control plan, including Cimarex's Change in Control Severance Plan. As a practical matter, the change in control benefits assumed under the employment agreements only benefit these executives if the Change in Control Severance Plan described above has been terminated. The Change in Control Severance Plan provides for greater benefits payable upon the occurrence of a change in control event than those payable under the assumed agreements.

Retirement Benefits

Employees, including the NEOs, are eligible to participate in the Cimarex 401(k) defined contribution retirement plan ("401(k) Plan"). Cimarex matches dollar-for-dollar employee contributions to the 401(k) Plan up to 7% of the employee's cash compensation, subject to limits imposed by the Internal Revenue Code. The Board is authorized to make profit-sharing contributions under the 401(k) Plan. In February 2018, the Board determined that a profit-sharing contribution of 4% would be made due to the Company's $494.3 million of net income in 2017.

In addition, eligible participants, including the NEOs, may participate in the Supplemental Savings Plan, which is a non-qualified deferred compensation plan that permits participants to make contributions (and to receive matching contributions) in excess of the Internal Revenue Code limitations for 401(k) plans. See "Compensation Tables—2017 Nonqualified Deferred Compensation" for information about contributions to the Supplemental Savings Plan. The Committee administers this plan and designates who may participate. Benefits are paid upon the later to occur of termination of employment or the time elected by the participant. In the event of a change in control, each participant receives a lump sum cash payment of the amount allocated to his or her account.

Perquisites

We offer a limited number of perquisites (personal benefits) to our NEOs that are not offered to other employees, including financial and estate planning and annual medical examinations. Our corporate aircraft is generally not available

Table of Contents

for personal use by any employee. With the authorization of our CEO, however, the corporate aircraft may be used by an employee or a member of his/her family for medical purposes. The incremental cost for non-business use of our corporate aircraft, if any, is disclosed in the "Summary Compensation Table." We use the Standard Industry Fare Level tables published by the Internal Revenue Service to determine the amount of compensation income that is imputed to the employee for tax purposes for personal use of corporate aircraft. Our corporate aircraft was used for one trip by an employee and his spouse for his spouse's medical care in 2017 with the authorization of our CEO. There was no other personal use of corporate aircraft during the year.

Other Compensation Policies

Total Pay Considerations

The Committee considers Total Direct Compensation at the time it makes a decision on any element of executive compensation. The Committee also reviews the relationship of the CEO's total compensation to the total compensation of each of the other NEOs.

Stock Ownership and Holding Requirements

Our Corporate Governance Guidelines require that each independent Director own Cimarex stock in an amount equal to three times his or her annual cash retainer. In addition, pursuant to a revision made in December 2016, the CEO is expected to own Cimarex shares in an amount equal to six times his annual base salary, and each executive officer who reports to the CEO is expected to own stock in an amount equal to three times his or her annual base salary. A newly elected Director or a newly appointed executive officer has three years from the date of his or her initial election or appointment to comply with the Guidelines. Until the stock ownership guidelines are met, an executive officer or Director may not sell any Cimarex stock acquired through equity grants except to pay income taxes upon the vesting of awards or to pay the exercise price and related income taxes upon the exercise of stock options. Restricted stock, restricted stock units, deferred compensation units and performance awards are counted in calculating ownership. Shares subject to options are not counted. As of March 30, 2018, all officers and independent Directors were in compliance with the stock ownership guidelines other than Frances M. Vallejo, who joined the Board on May 11, 2017. Ms. Vallejo has until May 11, 2020 to comply with the guidelines.

Clawback Policy

We have adopted a clawback policy providing that, in the event of an accounting restatement due to material noncompliance with financial reporting requirements under the U.S. federal securities laws, the Committee has the right to use reasonable efforts to recover from any of our current or former executive officers incentive-based compensation related to the restatement and received during the three-year period preceding any such accounting restatement. This policy applies to incentive-based compensation granted on or after June 1, 2012. This clawback policy will be interpreted in the best judgment of the Committee in a manner consistent with any applicable rules or regulations adopted by the SEC or the NYSE as contemplated by the Dodd-Frank Act.

Non-Hedging and Non-Pledging Policies

Our insider trading policy prohibits Directors, officers and designated employees from engaging in hedging or monetization transactions, and other employees are strongly discouraged from engaging in such transactions. Any other employee wishing to enter into such an arrangement must first submit the proposed transaction for approval by the compliance officer designated in the policy. The policy also prohibits Directors, officers and employees from holding Cimarex stock in a margin account or pledging Cimarex stock as collateral for a loan.

Tax Law Considerations

The Committee considers the impact of applicable tax laws with respect to executive compensation. Section 162(m) of the Internal Revenue Code of 1986, as amended, ("Section 162(m)") limits the amount of compensation that Cimarex may deduct on its federal income tax return for compensation paid to certain executive officers to no more than

50

---

Table of Contents

$1 million per year. Through 2017, there were exceptions to the $1 million limitation for performance-based compensation meeting certain requirements. The performance-based portion of our restricted stock awards made prior to November 2, 2017 are the only element of executive compensation designed to qualify for the performance-based exception to the $1 million deduction limit, provided additional requirements are met. These exceptions were eliminated by the Tax Cuts and Jobs Act enacted in December 2017. The Committee attempted to preserve the deductibility of compensation paid to executive officers by utilizing performance-based stock awards until this tax law change, but did not limit executive compensation to amounts deductible under Section 162(m) and does not plan to limit executive compensation to deductible amounts going forward.

COMPENSATION AND GOVERNANCE COMMITTEE REPORT

The Compensation and Governance Committee has reviewed and discussed with management the preceding Compensation Discussion and Analysis section of Cimarex's 2018 proxy statement. Based on our review and discussions, we have recommended to the Board of Directors that the Compensation Discussion and Analysis be included in Cimarex's 2018 proxy statement.

2017 GRANTS OF PLAN-BASED AWARDS

2017 Non-Equity Incentive Plan

The following table describes the target and maximum amounts of annual cash incentive awards for the CEO and other NEOs and the actual award paid in March 2018 for 2017 services. The non-equity incentive plan provides for no minimum (threshold) award. The amounts listed in the Target column represent 125% of the year-end base salary for CEO and 100% of the year-end base salary for other NEOs. The amounts listed in the Maximum column represent 250% of year-end base salary for CEO and 200% of the year-end base salary for other NEOs. See the description of our annual cash incentive award plan in "CD&A—Section 2."

2017 Equity Incentive Plan Awards

The following table provides information regarding the awards of restricted stock made to the NEOs in 2017. No option awards were made in 2017. See "CD&A—Section 2—Long Term Equity Incentive Award Program," for more information about these awards.

2017 NONQUALIFIED DEFERRED COMPENSATION

The following table provides information on the Supplemental Savings Plan (the "SSP") contributions and earnings for our NEOs in each of the last three fiscal years. Under the terms of the SSP, a participant may make an elective contribution to the SSP of an amount that exceeds the maximum amount permitted to be contributed to his account in the Cimarex 401(k) Plan (an "excess contribution") provided that the excess contribution does not exceed the dollar limitation on elective deferrals under the Internal Revenue Code section 402(g) in effect on January 1 of the calendar year of deferral (2017 limitation was $18,000). Cimarex will match 100% of the excess contributions up to 7% of a participant's eligible compensation. A participant also may elect to have up to 50% of his or her compensation and up

to 100% of his or her bonus withheld from his or her compensation and allocated to his or her SSP account. Cimarex does not match these contributions.

CEO PAY RATIO

Beginning with this proxy statement, prepared for the 2018 Annual Meeting of Shareholders, the SEC requires the disclosure of the ratio of the pay of the CEO and the identified median employee. The 2017 annual total compensation of our CEO, as shown in the "Summary Compensation Table" above, was $11,054,129. The annual total compensation of Cimarex's identified median employee was $119,127 in 2017. This results in a ratio of 93 to 1.

As noted above, Cimarex's executive compensation program links a significant portion of executive compensation to the Company's performance through variable pay programs, including annual and long term incentives. Consequently, 90% of the compensation of the Chief Executive Officer is considered "At Risk" pay and is only realized if Cimarex meets certain performance measures. By way of comparison, none of the median employee's compensation was at risk.

The median employee was identified from the total employee population as of December 31, 2017. Not including the CEO, this represents 891 full-time and 18 part-time or seasonal employees. We calculated the median total compensation by a simple array of lowest to highest of the wages reflected as Medicare Taxable Earnings as reported on Internal Revenue Service Form W-2 (Box 5) for 2017. We made no assumptions, adjustments, or estimates with regard to total compensation, and we did not annualize the compensation for any employees that were not employed by us the entire year.

POTENTIAL PAYMENTS UPON CHANGE IN CONTROL OR TERMINATION

We do not consider post-termination benefits as a material element of executive compensation because NEO post-termination benefits are the same benefits available to all full-time employees. Post-termination benefits are not included in the Compensation and Governance Committee's analysis of total compensation.

We are obligated to make certain payments to employees, including our NEOs, or to accelerate the vesting of their equity awards pursuant to the following plans and agreements:

•

Change in Control Severance Plan that covers all full-time employees, including the NEOs;



•

2002 Stock Incentive Plan, 2011 Equity Incentive Plan and 2014 Equity Incentive Plan that govern all equity awards made to Directors and employees, including the NEOs;



•

Change in control provisions for the benefit of Messrs. Albi, Bell, and Jorden, as assumed by Cimarex; and



•

Supplemental Savings Plan.

Our change in control arrangements keep our senior executives focused on pursuing all corporate transaction activity that is in the best interests of shareholders regardless of whether those transactions may result in their own job losses. Uncertainty created by a corporate transaction can create retention risk for a company. In addition, change in control protection is often needed to retain and attract, when appropriate, the best talent because many of the companies with whom we compete for talent provide change in control protection.

We do not have a formal program to pay severance benefits nor do our equity award agreements provide for acceleration of equity awards upon the retirement of the NEOs.

Change in Control

We are obligated under certain agreements to pay benefits upon a "change in control" event. Cimarex's definition of "change in control" as used in its 2002 Stock Incentive Plan, its 2011 Equity Incentive Plan and its 2014 Equity Incentive Plan, its Change in Control Severance Plan and the change in control provisions that survived certain expired

58

---

Table of Contents

employment agreements with each NEO are the same. In summary, a change in control event means any of the following:

•

Acquisition of 30% or more of the shares of our outstanding common stock or the combined voting power of voting securities of Cimarex by an individual or group;



•

Members of our Board of Directors, or Directors nominated by those Directors, cease to constitute a majority of the Directors during any period of twelve months;



•

A reorganization, share exchange or merger unless (i) the shareholders prior to the reorganization or merger continue to own more than 40% of the outstanding common stock and combined voting power of the resulting corporation following the reorganization or merger; and (ii) at least a majority of the members of the Board of the corporation resulting from the merger or reorganization were members of the Board at the time of executing the agreement to reorganize or merge; or



•

The complete liquidation or dissolution of Cimarex or the sale of all or substantially all of its assets.

The following is a summary of those agreements that provide for payment to the NEOs in the event of a change in control event coupled with termination of employment without cause:

Change in Control – Termination Without Cause

Our Change in Control Plan provides for the payment of severance benefits to all active employees in the event of termination following a change in control. In the event of a change in control, if an employee is terminated for any reason other than "cause" (as defined in the Plan) within two years following a change in control, that employee would be entitled to:

•

Cash severance payments of up to two years' salary and cash incentive award;



•

A pro rata portion of the annual cash incentive bonus award otherwise payable for the year of termination; and



•

Continued medical, dental, disability and life insurance benefits for two years.

We assumed from a predecessor company the change in control provisions from the now-expired employment agreements of each of Messrs. Albi, Bell, and Jorden with such company. Each agreement provides that if the executive is terminated without cause within two years following a change in control event (as defined in the agreement), the executive is entitled to a lump-sum payment equal to two times the executive's base salary at the time of the change in control. Benefits payable under these agreements are forfeited if the executive receives benefits under any other change in control plan, including the Cimarex Change in Control Severance Plan. As a practical matter, the change in control benefits assumed under the employment agreements only benefit these executives if the Change in Control Severance Plan described above has been terminated. The Change in Control Severance Plan provides for greater benefits payable upon the occurrence of a change in control event than those payable under the assumed agreements.

Change in Control – No Termination

Our 2002 Stock Incentive Plan, our 2011 Equity Incentive Plan, and our 2014 Equity Incentive Plan provide for acceleration of vesting of equity awards in the event of a change in control.

Termination of Employment

Death or Disability

The award agreements for grants of equity under the 2002 Stock Incentive Plan, and the provisions of the 2011 Equity Incentive Plan and 2014 Equity Incentive Plan, provide for acceleration of vesting of awards in the event of death or disability. Benefits under the Supplemental Savings Plan also are paid upon death or disability.

Termination Without Cause

Benefits under the Supplemental Savings Plan are payable to each NEO upon termination of employment.

Estimated Benefits upon Various Termination Scenarios

Payments upon a change in control or termination of employment include various elements of compensation. The elements of compensation that may be included in a change in control or severance payment are:

The following table provides the estimated compensation and present value of benefits potentially payable to each NEO in the event of a change in control or termination under various circumstances. The amounts shown assume that the termination or change in control occurred on December 31, 2017. The actual amounts to be paid only can be determined at the time of the executive's actual separation from Cimarex or the occurrence of a change in control.

Actual payments may be more or less than the amounts described below. In addition, the Company may enter into new arrangements or modify these arrangements, from time to time.

DIRECTOR AND OFFICER INDEMNIFICATION AGREEMENTS

We have entered into an indemnification agreement with our Directors and certain officers. These agreements require us, among other things, to indemnify such persons against certain liabilities that may arise by reason of their status or service as Directors or officers, to advance their expenses incurred as a result of a proceeding for which they may be indemnified, and to cover them under any Directors' and officers' liability insurance policy that we choose, in our discretion, to maintain. These indemnification agreements are intended to provide indemnification rights to the fullest extent permitted under applicable Delaware law and will be in addition to any other rights that the indemnitee may have under our Restated Certificate of Incorporation, Bylaws, and applicable law.

ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION (ITEM 2)

At the 2017 Annual Meeting of Shareholders, 97% of the votes cast were in favor of the advisory vote to approve executive compensation. In addition to the advisory vote, as part of our regular shareholder engagement, we consider and discuss with shareholders a number of matters throughout the year, including executive compensation and governance. The Compensation and Governance Committee carefully considers any feedback and routinely reviews executive compensation practices and governance.

The Compensation and Governance Committee considered the results of the advisory vote and the discussions with shareholders to convey our shareholders' support of the Committee's compensation decisions in 2016 and early 2017 and shareholders' overall satisfaction with Cimarex's executive compensation programs. Consistent with this support, the Compensation and Governance Committee retained the core design of our executive compensation programs for the remainder of 2017, as it believes the programs continue to retain, attract, when appropriate, and appropriately incent senior management.

At the 2018 Annual Meeting of Shareholders, we again will hold an annual advisory vote to approve executive compensation. The Compensation and Governance Committee will continue to consider the results from this year's and future advisory votes on executive compensation, as well as feedback from shareholders through the course of such year.

Because your vote is advisory, it will not be binding upon the Board. However, the Board values shareholders' opinions, and the Compensation and Governance Committee will take into account the outcome of the vote when considering future executive compensation decisions. The Board recommends that shareholders vote FOR the following resolution:

RESOLVED, that the shareholders approve, on an advisory basis, the compensation of Cimarex's Named Executive Officers, as disclosed in this proxy statement, including the Compensation Discussion and Analysis, the executive compensation tables and the related narrative.

The Board of Directors unanimously recommends a vote FOR the advisory vote to approve executive compensation.

REPORT OF AUDIT COMMITTEE

The Audit Committee on behalf of the Board of Directors monitors (i) the integrity of the Company's financial statements; (ii) the independent auditors' qualifications and independence; (iii) the performance of the Company's internal audit function and independent auditors; (iv) the appropriateness of the Company's accounting policies; (v) the adequacy of the Company's internal controls; (vi) the Company's compliance with legal and regulatory requirements related to audit matters; (vii) the process related to ongoing litigation matters; (viii) the annual process of estimating and reporting quantities of oil and gas reserves; and (ix) risk oversight. In so doing, it is the responsibility of the Committee to maintain free and open communication between the Directors, the independent auditor and the management of the Company. All members of the Audit Committee meet the independence, experience and financial literacy requirements of the New York Stock Exchange, the Sarbanes Oxley Act and any rules or regulations promulgated by the Securities and Exchange Commission. The Board of Directors has adopted a written charter for the Audit Committee, a copy of which is available on our website at www.cimarex.com.

Management is responsible for the Company's financial statements, the financial reporting process, and the process of estimating and reporting quantities of oil and gas reserves, including the related systems of internal controls and disclosure controls and procedures. The Company's independent registered public accounting firm is responsible for performing an independent audit of the Company's financial statements in accordance with generally accepted auditing standards, as well as an audit of the Company's internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB) and issuing reports thereon. The Audit Committee's responsibility is to monitor and oversee these processes and the Audit Committee uses the Company's internal audit department and (if applicable) independent petroleum engineers to assist with these responsibilities.

The Audit Committee reviewed Cimarex's audited financial statements and supplemental oil and gas reserve information as of and for the year ended December 31, 2017 and met with management, DeGolyer and MacNaughton (an independent petroleum engineering consulting firm) and KPMG, Cimarex's independent registered public accounting firm, to discuss the related information, and the effectiveness of Cimarex's internal control over financial reporting. In addition, the Audit Committee has received from KPMG the communication required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, and discussed with KPMG their independence from Cimarex and its management. The Audit Committee also discussed with KPMG any matters required by PCAOB Auditing Standard No. 1301, Communications with Audit Committees.

Based on these reviews and discussions, the Audit Committee recommended to the Board of Directors that Cimarex's audited financial statements be included in Cimarex's Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

The Audit Committee Report does not constitute soliciting material and shall not be deemed to be filed or incorporated by reference into any other Cimarex filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that Cimarex specifically incorporates the Audit Committee Report by reference.

RATIFICATION OF INDEPENDENT AUDITORS (ITEM 3)

The Audit Committee of the Board has appointed KPMG LLP to audit our financial statements for 2018. Since October 1, 2002, KPMG LLP has served as our independent auditors.

We are asking that shareholders ratify the appointment of KPMG LLP as our independent auditors. If shareholders fail to ratify the appointment, the Audit Committee may reconsider this appointment. A KPMG LLP representative will be at the Annual Meeting to answer appropriate questions and to make a statement if he or she desires.

The Board of Directors recommends a vote FOR the ratification of KPMG LLP as Cimarex's Independent Auditors for 2018.

Audit and Non-Audit Fees

The following table shows the fees for professional services rendered by KPMG LLP for the audit of Cimarex's annual financial statements for the years ended December 31, 2017 and December 31, 2016, and fees billed for other services rendered by KPMG LLP during those periods:

Approval of Audit, Audit-Related and Tax Services

The Audit Committee annually reviews and pre-approves certain categories of audit, audit-related and tax services to be performed by our independent auditors, subject to a specified range of fees. The Audit Committee also may pre-approve specific services. Certain non-audit services as specified by the SEC may not be performed by our independent auditors. The Audit Committee may delegate pre-approval authority to one or more of its members. In the event of any such delegation, any pre-approved decisions will be reported to the Audit Committee at its next scheduled meeting. The services described in the above table were pre-approved by the Audit Committee in 2016 and 2017.

OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our Directors and executive officers, and persons who own more than 10% of our common stock, to file reports of ownership of, and transactions in, our common stock with the SEC. Based on a review of such reports, and on written representations from our reporting persons, we believe that

all reports were timely filed in 2017. Subsequent to December 31, 2017, Harold R. Logan, Jr. reported on a Form 5 a late Form 4 transaction that originally occurred on February 22, 2012 due to a recently discovered administrative oversight.

Complaint and Reporting Procedures

We have established complaint and reporting procedures that are posted on our website at www.cimarex.com.
