To the Stockholders of Laredo Petroleum Holdings, Inc.:

        You are invited to attend our 2013 Annual Meeting of Stockholders, which will be held at the Thomas Gilcrease Museum, 1400 North Gilcrease Museum Road, Tulsa, Oklahoma 74127, on Thursday, May 16, 2013, at 3:00 p.m. Central Time.

        Details of the business to be conducted at the meeting are described in the attached Notice of 2013 Annual Meeting of Stockholders and Proxy Statement.

        We are mailing to most of our stockholders a Notice of Internet Availability of Proxy Materials ("Notice") instead of a paper copy of our Annual Report, which includes our Form 10-K for the fiscal year ended December 31, 2012, Proxy Statement and proxy card. We believe this process allows us to provide stockholders with the information needed in connection with our Annual Meeting in a timely manner, while saving costs and conserving resources. The Notice contains instructions on how to access these documents over the Internet, as well as instructions on how to request a paper copy of the materials, if desired. All stockholders who do not receive a Notice should receive a paper copy of the proxy materials by mail.

        Your vote is important and we encourage you to vote whether or not you plan to attend the meeting. Please either vote by telephone, over the Internet or sign, date and return your proxy card, following the instructions on the Notice or proxy materials, so that your shares will be represented. If you are a stockholder of record and plan to attend the meeting, you may also vote in person.

        We look forward to seeing you at the meeting.

By granting the proxy, you authorize the persons named on the proxy to represent you and vote your shares at the Annual Meeting. Those persons will also be authorized to vote your shares to adjourn the Annual Meeting from time to time and to vote your shares at any adjournments or postponements of the Annual Meeting.

        In accordance with the rules and regulations adopted by the Securities and Exchange Commission ("SEC"), we are providing our stockholders access to our proxy materials on the Internet.

Stockholders will have the ability to access the proxy materials on the website referred to in the Notice, or request a printed set of the proxy materials to be sent to them by following instructions on the Notice.

        If you choose to receive future proxy materials by e-mail, you will receive an e-mail next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by e-mail or printed form will remain in effect until you terminate it.

Q.    Who is entitled to vote at the Annual Meeting?

Holders of record of our common stock at the close of business on March 20, 2013, which we refer to as the "Record Date," are entitled to vote at the Annual Meeting.

Q.    Why did I receive a Notice in the mail regarding the Internet availability of proxy materials this year instead of a full set of proxy materials?

A.

In accordance with SEC rules, we are providing access to our proxy materials over the Internet. As a result, we are sending to most of our stockholders a Notice instead of a paper copy of the proxy materials. The Notice contains instructions on how to access the proxy materials over the Internet and how to request a paper copy. In addition, stockholders may request to receive future proxy materials in printed form by mail or electronically by e-mail. A stockholder's election to receive proxy materials by mail or e-mail will remain in effect until the stockholder terminates it.

Q.    Why didn't I receive a Notice in the mail regarding the Internet availability of proxy materials?

A.

We are providing certain stockholders, including those who have previously requested to receive paper copies of the proxy materials, with paper copies of the proxy materials instead of a Notice. If you would like to help reduce the costs we incur in mailing proxy materials, you can consent to receive all future proxy statements, proxy cards and annual reports electronically via e-mail or the Internet. To sign up for electronic delivery, please follow the instructions provided with your proxy materials and on your proxy card or voting instruction card to vote using the Internet. When prompted, indicate that you agree to receive or access stockholder communications electronically in the future.

Q.    Can I vote my stock by filling out and returning the Notice?

A.

No. However, the Notice will provide instructions on how to vote over the Internet, by telephone, by requesting and returning a paper proxy card or by submitting a ballot in person at the Annual Meeting.

Q.    How can I access the proxy materials over the Internet?

A.

Your Notice or proxy card will contain instructions on how to view our proxy materials on the Internet. Our proxy materials are also available on our website at: www.laredopetro.com.

You may vote by any of the following four methods:

(1)

Internet.    Vote over the Internet at www.voteproxy.com, the web site for Internet voting. Simply follow the instructions on the Notice, or if you received a proxy card by mail, follow the instructions on the proxy card and you can confirm that your vote has been properly recorded. If you vote on the Internet, you can request electronic delivery of future proxy materials. Internet voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m. (Eastern Time) on May 15, 2013.



(2)

Telephone.    Vote by telephone by following the instructions on the Notice, or if you received a proxy card, by following the instructions on the proxy card. Easy-to-follow voice prompts allow you to vote your shares and confirm that your vote has been properly recorded. Telephone voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m. (Eastern Time) on May 15, 2013.



(3)

Mail.    If you received a proxy card by mail, vote by mail by completing, signing, dating and returning your proxy card in the pre-addressed, postage-paid envelope provided. If you vote by mail and your proxy card is returned unsigned, then your vote cannot be counted. If you vote by mail and the returned proxy card is signed without indicating how you want to vote, then your proxy will be voted as recommended by the board of directors. If mailed, your completed and signed proxy card must be received by May 15, 2013.



(4)

Meeting.    If you are a stockholder of record, you may attend and vote at the Annual Meeting.

Table of Contents

If you hold your Laredo shares in a brokerage account, your ability to vote over the Internet or by telephone depends on your broker's voting process. Please follow the directions on your proxy card or the voter instruction card from your broker carefully.

The board of directors recommends that you vote using one of the first three methods discussed above, as it is not practical for most stockholders to attend and vote at the Annual Meeting. Using one of the first three methods discussed above to vote will not limit your right to vote at the Annual Meeting if you later decide to attend in person.

Q.    How can I vote my shares in person at the Annual Meeting?

A.

Stockholders of Record.    If your shares are registered directly in your name with the American Stock Transfer and Trust Company, our "transfer agent," you are considered the stockholder of record with respect to those shares and the Notice or proxy materials being mailed to you. As the stockholder of record, you have the right to vote in person at the Annual Meeting. If you choose to do so, you can bring the proxy card or vote using the ballot provided at the Annual Meeting. Even if you plan to attend the Annual Meeting, we recommend that you vote your shares in advance as described below so that your vote will be counted if you decide later not to attend the Annual Meeting.

Beneficial Owners.    Most of our stockholders hold their shares in street name through a broker, bank or other nominee rather than directly in their own name. In that case, you are considered the beneficial owner of shares held in street name, and the proxy materials are being forwarded to you together with a voting instruction card. As the beneficial owner, you are also invited to attend the Annual Meeting. Because a beneficial owner is not the stockholder of record, you may not vote these shares in person at the Annual Meeting unless you obtain a "legal proxy" from the broker, bank or nominee that holds your shares, giving you the right to vote the shares at the meeting. You will need to contact your broker, bank or nominee to obtain a legal proxy, and you will need to bring it to the Annual Meeting in order to vote in person.

Q.    How does the board of directors recommend that I vote?

A.

Our board of directors recommends that you vote:

(1)

"FOR" the election of the Company's nominees to the board of directors.

(2)

"FOR" ratification of the appointment of Grant Thornton LLP as our independent registered public accounting firm for the year ending December 31, 2013.

(3)

"FOR" the advisory resolution approving the compensation of our named executive officers as disclosed in this Proxy Statement (which disclosure includes the Compensation Discussion and Analysis, the executive compensation tables and the related footnotes and narrative accompanying the tables).

Q.    What is the voting requirement to approve each of the items?

Q.    What happens if additional matters are presented at the Annual Meeting?

A.

Other than the three items of business described in this Proxy Statement, we are not aware of any other business to be acted upon at the Annual Meeting. If you grant a proxy, the persons named as proxies will have the discretion to vote your shares on any additional matters properly presented for a vote at the Annual Meeting.

Q.    What happens if I do not give specific voting instructions?

A.

If you are a stockholder of record, and you sign and return a proxy card without giving specific voting instructions, the proxyholders will vote your shares in the manner recommended by our board of directors on all matters presented in this Proxy Statement, and, with respect to any other matters that may properly come before the Annual Meeting, as the proxyholders may determine in their discretion.

You should use the voting instruction card provided by the institution that holds your shares to instruct your broker to vote your shares or else your shares will be considered broker non-votes. If you are the beneficial owner of shares held in the name of a broker, bank or other nominee and do not provide that broker, bank or other nominee with voting instructions, your shares may constitute "broker non-votes." Generally, broker non-votes occur when a broker is not permitted to vote on a matter without instructions from the beneficial owner and such instructions are not given. In tabulating the voting results for any particular proposal, shares that constitute broker non-votes are not considered entitled to vote on that proposal. Thus, broker non-votes will not affect the outcome of any matter being voted on at the meeting, assuming that a quorum is obtained.

If you hold your shares through a broker, bank or other nominee and you do not provide your broker with specific voting instructions, your broker may vote your shares only with respect to certain matters considered routine. Specifically, your broker may not vote on the election of directors or the compensation of our named executive officers if you do not furnish instructions for this item. Your broker may vote in its discretion on the ratification of the appointment of our independent public accounting firm.

Table of Contents

Q.    What is the quorum requirement for the Annual Meeting?

A.

A majority of the Company's outstanding shares as of the Record Date must be present, in person or by proxy, at the Annual Meeting in order to hold the Annual Meeting and conduct business. This is called a quorum. Your shares will be counted for purposes of determining if there is a quorum, whether representing votes for, against, withheld or abstained, if you:

•

are present and vote at the Annual Meeting; or

•

properly submit a proxy card or vote over the Internet or by telephone.

Broker non-votes are counted as present for the purpose of determining the existence of a quorum at the Annual Meeting. If a quorum is not present, the chairman of the Annual Meeting may adjourn the meeting to another place, if any, date, or time.

Q.    How can I change my vote after I return my proxy card?

A.

If you are a stockholder of record, there are three ways you can change your vote or revoke your proxy after you have sent in your proxy form.

•

First, you may send a written notice to Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119, stating that you would like to revoke your proxy.

•

Second, you may complete and submit another valid proxy by mail, telephone or over the Internet that is later dated and if mailed, is properly signed, or if submitted by telephone or over the Internet is received by 11:59 p.m. Eastern Time on May 15, 2013. Any earlier proxies will be revoked automatically.

•

Third, you may attend the Annual Meeting and vote in person. Any earlier proxy will be revoked. However, attending the Annual Meeting without voting in person will not revoke your proxy.

If you hold your shares through a broker, bank or other nominee and you have instructed the broker, bank or other nominee to vote your shares, you must follow directions from your broker, bank or other nominee to change your vote.

Q.    Who will tabulate the votes?

A.

The board of directors has appointed our transfer agent, American Stock Transfer and Trust Company ("AST"), to tabulate and certify the vote, and AST will have a representative to act as the independent inspector of elections for the Annual Meeting. AST will be responsible for (i) determining the presence of a quorum at the Annual Meeting, (ii) receiving all votes and ballots, whether by proxy or in person, with regard to all issues voted upon at the Annual Meeting, (iii) counting and tabulating all such votes and ballots and (iv) determining and reporting the results with regard to all such issues voted upon at the Annual Meeting.

Q.    Where can I find the voting results of the Annual Meeting?

A.

We intend to announce preliminary voting results at the Annual Meeting and publish preliminary results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

Q.    How can I obtain a separate set of proxy materials?

A.

We have adopted a procedure approved by the SEC known as "householding." Under this procedure, multiple stockholders residing at the same address have the convenience of receiving a

5

---

Table of Contents

single copy of our Annual Report and Proxy Statement, unless they have notified us that they want to continue receiving multiple copies. Householding allows us to reduce the environmental impact of providing proxy materials as well as printing and mailing costs.

If you received a householded mailing this year and you would like to have additional copies of the Annual Report and/or Proxy Statement mailed to you, or you would like to revoke your consent to the householding of documents, please submit your request to Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119 or by calling (918) 513-4570.

Unfortunately, householding for bank and brokerage accounts is limited to accounts within the same bank or brokerage firm. For example, if you and your spouse each have two accounts containing our common stock at two different brokerage firms, your household will receive two copies of our Annual Meeting materials—one from each brokerage firm. To reduce the number of duplicate sets of materials your household receives, you may wish to enroll some or all of your accounts in our electronic delivery program.

Q.    Who pays for the cost of this proxy solicitation?

A.

We will pay the costs of the solicitation of proxies. We may reimburse brokerage firms and other persons for expenses incurred in forwarding the voting materials to their customers who are beneficial owners and obtaining their voting instructions. In addition to soliciting proxies by mail, our board members, officers and employees may solicit proxies on our behalf, without additional compensation, personally or by telephone. Stockholders voting over the Internet should understand that there may be costs associated with electronic access, such as the usage charges from telephone companies and Internet access providers, that must be borne by the stockholder.

Q.    Is there a list of stockholders entitled to vote at the Annual Meeting?

A.

The names of stockholders of record entitled to vote at the Annual Meeting will be available at the Annual Meeting and for ten days prior to the Annual Meeting at our principal executive offices between the hours of 9:00 a.m. and 5:00 p.m. Central Time for any purpose relevant to the Annual Meeting. To arrange to view this list during the times specified above, please contact the Secretary of the Company at Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119.

Q.    What is the deadline to propose actions for consideration at next year's annual meeting?

A.

Shareholders who, in accordance with Rule 14a-8 under the Securities Exchange Act of 1934, as amended, which we refer to as the "Exchange Act," wish to present proposals for inclusion in the proxy materials to be distributed in connection with the 2014 annual meeting of stockholders, must submit their proposals so that they are received at our principal executive offices no later than the close of business on December 3, 2013, or, in the event the Company's 2014 annual meeting is advanced or delayed more than 30 days from the date of the Annual Meeting, within a reasonable time before the Company begins to print and mail the proxy materials for the 2014 annual meeting. As the SEC rules make clear, simply submitting a proposal does not guarantee that it will be included in the Company's proxy materials.

In addition, stockholders who wish to introduce a proposal from the floor of the 2014 annual meeting of stockholders (outside the processes of Rule 14a-8), must submit that proposal in writing to the Company's Secretary at our principal executive offices no earlier than January 17, 2014 and no later than February 16, 2014, or, in the event the Company's 2014 annual meeting of stockholders is advanced or delayed more than 30 days from the date of the anniversary of the Annual Meeting, not later than the later of (i) the 90th day before the 2014 annual meeting or

6

---

Table of Contents

(ii) the 10th day following the day on which public announcement of the date of the 2014 annual meeting is first made by the Company.

To be in proper form, a stockholder's notice must include the information required by our bylaws with respect to each proposal submitted. The Company may refuse to consider any proposal that is not timely or otherwise does not meet the requirements of our bylaws or the SEC's rules with respect to the submission of proposals.

You may obtain a copy of our bylaws by accessing our website (www.laredopetro.com) or submitting a request to Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119.

Q.    How do I nominate a candidate for election as a director?

A.

Stockholders who wish to nominate a candidate for election as a director at our 2014 annual meeting must submit their nomination in writing to the Company's Secretary at our principal executive offices no earlier than January 17, 2014 and no later than February 16, 2014, or, in the event the Company's 2014 annual meeting of stockholders is advanced or delayed more than 30 days from the date of the Annual Meeting, not later than the later of (i) the 90th day before the 2014 annual meeting or (ii) the 10th day following the day on which public announcement of the date of the 2014 annual meeting is first made by the Company.

In the event that the number of directors to be elected to the board of directors is increased and there has been no public announcement naming all of the nominees for director or indicating the increase made by the Company at least 10 days before the last day a stockholder may deliver a notice of nomination in accordance with the preceding sentence, a stockholder's notice will be considered timely, but only with respect to nominees for any new positions created by such increase, if it is received by the Secretary at the principal executive offices of the Company not later than the close of business on the 10th day following the day on which such public announcement is first made by the Company.

To be in proper form, a stockholder's notice must include the information required by our bylaws with respect to the nomination and all other information regarding the proposed nominee and the nominating stockholder required by Section 14 of the Exchange Act and the rules and regulations promulgated thereunder. The Company may refuse to consider any nomination that is not timely or otherwise does not meet the requirements of our bylaws or the SEC's rules with respect to the submission of director nominations. A written statement from the proposed nominee consenting to be named as a candidate and, if nominated and elected, to serve as a director should accompany any stockholder nomination.

Q.    How can I communicate with the board of directors?

A.

Stockholders or other interested parties can contact any director, any committee of the board of directors, or the Company's non-management directors as a group, by writing to Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119. Comments or complaints relating to the Company's accounting, internal accounting controls or auditing matters will also be referred to members of the Audit Committee. All such communications will be forwarded to the appropriate member(s) of the board of directors.

THIS QUESTION AND ANSWER SECTION IS ONLY MEANT TO GIVE AN OVERVIEW OF THE PROXY STATEMENT. FOR MORE INFORMATION, PLEASE REFER TO THE MATERIAL CONTAINED IN THE SUBSEQUENT PAGES.

NOTE REGARDING OUR CORPORATE REORGANIZATION

        On December 19, 2011, pursuant to the terms of a corporate reorganization completed prior to the closing of the Company's initial public offering, the Company merged with Laredo Petroleum, LLC ("Laredo LLC"), with the Company being the surviving entity. All of Laredo LLC's outstanding preferred equity units were exchanged for shares of the Company's common stock in accordance with the limited liability company agreement of Laredo LLC ("LLC Agreement"). In addition, under the LLC Agreement and the restricted unit agreements, certain series of Laredo LLC's incentive equity units were exchanged into the Company's common stock. To the extent any of such incentive units were subject to vesting requirements, the common stock issued in exchange therefor is also subject to such requirements.

        We refer to (i) the merger of the Company and Laredo LLC, (ii) the exchange of all of the outstanding preferred equity units and certain series of incentive equity units of Laredo LLC for shares of the Company's common stock in accordance with the LLC Agreement and (iii) the consummation of the other related transactions collectively as our "corporate reorganization."

        As used in this Proxy Statement, the term "Laredo" refers to the Company and its subsidiaries for periods after the corporate reorganization and to Laredo LLC and its subsidiaries for periods prior to the corporate reorganization.

        THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE ELECTION OF EACH OF THE NOMINEES.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

        The following discussion and analysis contains statements regarding our and our named executive officers' future performance targets and goals. These targets and goals are disclosed in the limited context of our compensation programs and should not be understood to be statements of management's expectations or estimates of results or other guidance.

Introduction

        The following compensation discussion and analysis describes the material elements of compensation for our named executive officers as determined by the Company's Compensation Committee for 2012. In particular, this "Compensation Discussion and Analysis" (1) provides an overview of Laredo's historical and proposed compensation policies and programs; (2) explains our compensation objectives, policies and practices with respect to our executive officers; and (3) identifies the elements of compensation for each of the individuals identified in the "Named Executive Officers" table, who we refer to in this "Compensation Discussion and Analysis" as our "named executive officers."

Table of Contents

Named Executive Officers

        For the 2012 fiscal year, our named executive officers were:

        Messrs. Foutch, Buterbaugh and Womble are named executive officers by reason of their positions as the principal executive and financial officers of the Company during the year (or, in the case of Mr. Womble and Mr. Buterbaugh, a portion thereof), and each of Messrs. Schuyler, Curth and Minton are named executive officers by reason of them being our three most highly compensated officers other than Messrs. Foutch, Buterbaugh and Womble.

2012 Company Highlights

        In 2012, we accomplished several goals as we grew reserves, production and operating cash flow. We continued to delineate and de-risk our core assets in the Permian Basin. Among our highlights in 2012 were the following:

Summary of our Compensation Program

        Compensation of our executive officers has historically included the following key components:

        The progress of the Company in 2012, including but not limited to the continued growth of production and reserves, as well as the further delineation of our overall resource potential (particularly in the Permian Basin), resulted in management's recommendation and the Compensation Committee's determination to endorse the executive compensation framework and elements discussed in this "Compensation Discussion and Analysis" section as being in the best interests of the Company.

Process for Determining Executive Compensation

Administration of our compensation programs

        Our executive compensation program is overseen by the Compensation Committee. The purpose of the Compensation Committee is to supervise the administration of compensation programs for all our officers and employees and those of our subsidiaries, including Laredo Petroleum, Inc. Officer compensation is reviewed at least annually for possible adjustments by the Compensation Committee.

Compensation philosophy and objectives of our executive compensation program

        Since our inception, we have grown by focusing on the exploration and development of oil and natural gas in the Permian and Mid-Continent regions of the United States. Our compensation philosophy has been primarily focused on recruiting and motivating individuals to help us continue that growth. Our executive compensation program is designed to attract, retain and motivate highly qualified and committed personnel by compensating them with both long-term incentive compensation in the form of equity, options and performance units, and short-term cash compensation comprising salary and the possibility of annual bonuses.

Implementing our objectives

        Executive compensation decisions are made on an annual basis by the Compensation Committee with input from Messrs. Foutch, Schuyler, Buterbaugh and Kenneth E. Dornblaser, our Senior Vice President, General Counsel and Secretary. Although the Compensation Committee considers the input received from these executive officers, compensation decisions are ultimately recommended by the Compensation Committee and approved by the board of directors.

        From time to time, Messrs. Foutch, Schuyler, Buterbaugh and Dornblaser obtain and review external market information (including that received from the Compensation Committee's independent compensation advisor, as more fully described below) to assess the Company's ability to provide

19

---

Table of Contents

competitive compensation packages to our executive officers and recommend an adjustment to the compensation levels, when necessary. In making executive compensation recommendations, Messrs. Foutch, Schuyler, Buterbaugh and Dornblaser consider both the Company's and the executive officers' performance during the year. Moreover, an executive officer's expanded role at the Company could also serve as a basis for adjustment. Specifically, Messrs. Foutch, Schuyler, Buterbaugh and Dornblaser provide recommendations to the Compensation Committee regarding the compensation levels for our existing officers (excluding themselves) and our compensation program as a whole.

        While the Compensation Committee gives considerable weight to Messrs. Foutch's, Schuyler's, Buterbaugh's and Dornblaser's input on compensation matters, the board of directors, after considering the recommendations of the Compensation Committee, has the final decision-making authority on all officer compensation matters. No other executive officers have a role in the evaluation, design or administration of our executive officer compensation program.

Compensation Best Practices

        The Company maintains compensation arrangements intended to optimize returns to shareholders and include best practice features, such as:

Shareholder Say-on-Pay Results

        In addition to these practices, at our 2012 Annual Meeting, our executive compensation program received the support of more than 99% of shares voted at the meeting. The Compensation Committee has considered these results and viewed this outcome as evidence of stockholder support of its executive compensation decisions and policies. Accordingly, the Compensation Committee substantially maintained our executive compensation policies for 2012. The Compensation Committee will continue to review stockholder votes on our executive compensation and determine whether to make any changes to the program as a result of these votes.

Compensation Consultant and Conflict of Interest Analysis

        In July 2011, the Compensation Committee engaged Cogent Compensation Partners, Inc. ("Cogent") to serve as its independent compensation advisor. In July 2012, Cogent was acquired by Frederic W. Cook & Co., Inc. ("FWC") at which time the Compensation Committee confirmed the retention of FWC as its independent compensation advisor. FWC did not provide any other services to the Company that were not authorized by the Compensation Committee. In accordance with the requirements of Item 407(e)(3)(iv) of Regulation S-K, in 2012 the Compensation Committee considered the relationships that Cogent and FWC have had with the Company, the members of the Compensation Committee and our executive officers, as well as the policies that Cogent and FWC have in place to maintain their independence and objectivity, and determined that no conflicts of interest

20

Table of Contents

arose from the work performed by Cogent and FWC. It is anticipated that the relationship will continue during 2013. The Compensation Committee's objective when engaging Cogent and FWC was to assess our level of competitiveness for executive-level talent and provide recommendations for attracting, motivating and retaining key employees, including identifying industry best practices.

        FWC's initial report was presented to Laredo LLC's board of managers as a whole in August 2011. The report, which has since been updated as of January 1, 2012, was utilized by the Compensation Committee when making its recommendations to the Company's board of directors for the compensation programs and adjustments to the current programs that were made in 2012 and later, as described below.

Competitive Benchmarking

        At the request of the Compensation Committee, FWC identified potential peer companies for use in benchmarking our compensation policies. FWC used the following parameters when constructing the peer group for its assessment: (1) resource-focused exploration and production companies that are publicly traded, (2) companies with a good performance track record, (3) companies with a strong management team with technical expertise, and (4) companies with revenue between $100 million and $1 billion.

        Using these parameters and collaborating with Messrs. Foutch, Schuyler and Womble and members of the Compensation Committee, Cogent developed and originally recommended a 17-company industry peer group which was approved by the Compensation Committee and by Laredo LLC's board of managers. The peer group included the following companies:

Elements of Compensation

        Compensation of our executive officers has historically included the following key components:

Table of Contents

        In addition, in early 2012 we rewarded certain employees, including our named executive officers, with a one-time special bonus related to their efforts associated with the preparation and completion of our initial public offering.

Pay Mix

        The following tables set forth (1) the approximate percentage of each named executive officer's total compensation that Laredo paid in the form of (i) base salary and cash bonus awards and (ii) equity awards during fiscal year 2012 as set forth in the "Summary compensation table" below and (2) the allocation of base salary, target annual cash bonus and target long-term incentive awards of our Chief Executive Officer and other named executive officers for 2013 (assuming each such person receives their target percentage for STIP and LTIP awards). We view the various components of compensation as related but distinct and emphasize "performance" by tying significant portions of total compensation to short- and long-term financial and strategic goals, currently in the form of base salaries, annual cash bonus awards and long-term plan-based incentive awards. Our compensation philosophy is designed to align the interests of our employees with those of our stockholders. For more information regarding the restricted unit awards, see the "Grants of plan-based awards table for the year ended December 31, 2012." We also attempt to set each officer's base salary in line with comparable positions with our peers and to award an annual cash bonus based on the achievement of overall Company strategic goals and each individual's relative contribution to those goals.

Chief Executive Officer—2013 Estimated Pay Mix

Other named executive officers combined—2013 Estimated Pay Mix

Base Salaries

        Purpose:    Base salaries are designed to provide a fixed level of cash compensation for services rendered during the year.

        Competitive Positioning:    For base salaries, we target approximately the market median, because we believe this market mid-point allows us to attract and retain qualified personnel. In 2012, the aggregate base salaries for our named executive officers was approximately 90% of the market median.

        Process for Setting Base Salaries:    Base salaries are reviewed at least annually, but are not adjusted if the Compensation Committee believes that our executives are compensated at proper levels in light of either our internal performance or external market factors.

23

---

Table of Contents

        In addition to providing a base salary that we believe is competitive with peers, we also consider internal pay equity among each of our named executive officer's salary levels relative to the salary levels of our other officers so that it accurately reflects the officer's relative skills, responsibilities, experience and contributions to the Company. Annual salary adjustments are based on a subjective analysis of many individual factors, including:

        In addition to the individual factors listed above, we also take into consideration our overall business performance and implementation of Company objectives, as well as industry trends. While these factors generally provide context for making salary decisions, base salary decisions do not depend directly on attainment of specific goals or performance levels and no specific weighting is given to one factor over another.

Base Salary for 2012 and 2013

        The following table identifies the base salaries of our named executive officers during 2012, as well as the base salaries adopted by the Compensation Committee for such persons in February 2013 for the remainder of 2013:

        The Company's board of directors approved increases in the base salaries of Laredo's named executive officers for 2013 as shown in the table above. The salary increases were effective as of February 10, 2013. The rationale for increasing base salaries was to adjust base salaries to approximately the median of our peer group, consistent with Laredo's compensation strategy. FWC reported that prior to the adjustment, base salaries of Laredo's named executive officers were approximately 90% of the market median. Mr. Buterbaugh was not given an additional salary increase in 2013 since he was promoted late in 2012.

Annual Cash Bonus Awards

        Purpose:    Annual cash bonus awards are a key part of each named executive officer's annual compensation package. The Compensation Committee believes that cash bonuses are an appropriate way to further the Company's goals of attracting, retaining and rewarding highly qualified and experienced officers. Cash bonuses are generally awarded annually following completion of the service year for which bonuses are payable and are based primarily on Laredo's performance for such service year, but consideration is also given to individual performance and specific contribution to Laredo's success and performance.

        Competitive Positioning:    For annual cash bonus awards, the Company targets approximately the market median. In 2012, the Company was positioned at 81% of the market median. We believe targeting the market median allows us to attract and retain qualified personnel.

        Plan mechanics:    For the 2012 fiscal year, annual cash bonuses were determined in two parts at the sole discretion of the Compensation Committee for ultimate approval by the board of directors. Consistent with the historical practices of Laredo, 50% of the cash bonus award for each named executive officer was determined by the 2012 Bonus Performance Metric Results described below, while the remaining 50% was subjectively determined by the Compensation Committee considering the Company's overall performance in other areas. Individual adjustments were made after considering input provided by Messrs. Foutch and Schuyler regarding both Company performance in other areas as well as individual performance factors such as leadership, commitment, attitude, motivational effect, level of responsibility and overall contribution to Laredo's success (but excluding with respect to Mr. Foutch's own performance, which was solely determined by the Compensation Committee). Although our cash bonus program includes the Company performance goals and objectives, our Compensation Committee has the ultimate discretion to recommend to the board of directors whether to award any, and the amount of, cash bonus awards, even if the Bonus Performance Metric Results do not satisfy the Bonus Performance Metric Targets.

        Performance Metrics and Results:    The 2012 Bonus Performance Metric Results consisted of the following performance metric categories and targets for the Company (the targets reflected in Laredo's 2012 internal budget), with the percentile as recommended by the Compensation Committee and approved by the board of directors:

        These particular metric categories were selected, in part, due to our historical use of similar metrics prior to our initial public offering for similar compensation purposes. We believe the metrics

25

Table of Contents

captured several critical performance criteria to provide a quantitative measure of overall Company performance.

        Effective for 2013, following consultation between FWC and our Compensation Committee and the consideration and recommendation by the Compensation Committee and approval by the board of directors, we have modified the performance metrics and weightings, primarily to more closely align the metrics with those metrics we believe to be prevalently used in modeling by the investment community, as well as by our peer group. The metric categories and relative weighting to be applied to our 2013 fiscal year performance are set forth below.

        In addition, based primarily on the recommendation of FWC following their analysis of our peer group metrics, the Compensation Committee determined that effective for fiscal year 2013, 60% of the cash bonus awards will be determined by the 2013 performance metrics described above, while the remaining 40% will be subjectively determined by the Compensation Committee, considering the Company's overall performance in other areas.

        Target Award Levels:    Target incentive levels for short-term incentive payouts for 2012 for each named executive officer are listed below. Award levels are calculated on a threshold level of 50% of target and a maximum of 200% of target. The annual incentive target percentage varies by named executive officer and is based on differing job classifications and responsibilities. Each position is compared to similar positions in the market as well as our peer companies.

Short-term incentive payouts for 2012 performance

        Following the Compensation Committee's review of the 2012 Performance Metrics Results as well as the subjective results of the Company as described above, the Compensation Committee approved Mr. Foutch's recommendations for cash bonuses for his direct reports and the Compensation Committee also approved an award for Mr. Foutch. For fiscal year 2012, the board of directors primarily looked to the Company's accomplishments which are stated above under "2012 Company Highlights" in determining subjective performance criteria. Based on a combination of both the performance metrics results and the subjective results noted above, the Compensation Committee determined the Company's overall performance resulted in a 90% payout. This percentage was arrived at following the Compensation Committee's determination that the Company achieved roughly an 80% target level on its overall 2012 Bonus Performance Metric Results and a 100% level on the subjective criteria identified in part under "2012 Company Highlights." The Compensation Committee agreed to a pro-rated payout to Mr. Buterbaugh based on his hire date of June 1, 2012, and a reduction in the annual bonus for Mr. Womble based on his transition to retirement. The short-term incentive bonuses approved by the Compensation Committee to the named executive officers averaged 87% of the target bonus amounts aligning with the overall performance rating percentage, with the individual awards identified in the following table. The amounts shown under the "Recommended Award" column were paid to the named executive officers after our financial statements had been completed and our Annual Report on Form 10-K filed in March 2013.

        In addition to base salary increases described previously, FWC also proposed increasing short-term incentive targets as a percentage of base pay for Mr. Foutch to 110% and Mr. Schuyler to 90% for the 2013 STIP. The decision was made after reviewing market median data for total cash compensation for executives in our peer group. The Compensation Committee and board of directors approved the recommendation.

Long-term Plan-Based Incentive Awards

        In connection with our initial public offering in late 2011, we adopted the Laredo Petroleum Holdings, Inc. 2011 Omnibus Equity Incentive Plan in 2011 (the "2011 Plan"). The purpose of the 2011 Plan is to provide a means for use to attract and retain key personnel and for our directors, officers, employees, consultants and advisors to acquire and maintain an equity interest in the Company, thereby strengthening their commitment to the welfare of the Company and aligning their interests with those of the Company's stockholders.

Table of Contents

        Purpose:      Our historical long-term plan-based incentive program was designed to provide our employees, including our named executive officers, with an incentive to focus on our long-term success and to act as a long-term retention tool by aligning the interests of our employees with those of our stockholders.

        Competitive Positioning:    For long-term plan-based incentive awards, the Company targets between the market median and market 75^th percentile of comparable long-term incentive compensation. In 2012, the named executive officers were positioned at 78% of the market median and 57% of the market 75^th percentile.

        Target Award Levels:    Target incentive levels for long-term incentive payouts for 2012 for each named executive officer are listed below and are calculated as a percentage of base salary. The long-term incentive target percentage varies by named executive officer and is based on differing job classifications and responsibilities. Each position is compared to similar positions in the market as well as our peer companies.

        Long-Term Incentive Vehicles:    For corporate officers the Company targets a long-term incentive vehicle mix of approximately 25% restricted stock, 25% stock options, and 50% performance units. This mix of incentive vehicles, as well as the applicable vesting periods described below, were adopted by the board of directors following the recommendation of FWC and a review of comparable awards granted by our peer group and the industry in general.

        Restricted Stock:    The restricted shares of our common stock are subject to forfeiture until vested. So long as the recipient of such shares is an employee of the Company, the shares granted to each recipient will vest, and the transfer restrictions thereon will lapse ratably over three years. Each recipient will forfeit his or her unvested shares if the recipient's employment is terminated by us for any reason or if the recipient resigns (in either case, other than for death or disability). We believe that this vesting schedule is comparable to those utilized by the peer group and will assist us in attracting new talent and retaining existing personnel. Restricted shares of common stock will be granted to new employees upon hire, based on their relative entry level into the Company.

        Stock Options:    Stock options provide the opportunity to purchase our stock at a price that is fixed on the grant date regardless of the future market price. If our stock price does not increase, then these stock options will have little to no economic value. Pursuant to the terms of the 2011 Plan, the

28

Table of Contents

exercise price for each stock option is the closing price of a share of stock on the New York Stock Exchange ("NYSE") on the grant date.

        The stock options vest ratably over four years. As with the restricted shares of our common stock, we believe that this vesting schedule is comparable to those utilized by our peer group and will allow us to both attract new talent and retain existing personnel. The unvested portion of a stock option will expire upon termination of employment of the optionee, and the vested portion of a stock option will remain exercisable for (i) one year following termination of employment by reason of the optionee's death or disability or (ii) 90 days for any other reason, other than for cause. Both the unvested and vested (but unexercised) portion of a stock option will expire upon the termination of the optionee's employment by us for cause. Unless sooner terminated, the stock option will expire if and to the extent it is not exercised within 10 years from the date of the grant. Generally, grants of stock options will be made in the first quarter of each year.

        Performance Units:    The performance units granted to each recipient are payable in cash based upon the achievement by the Company over a three-year performance period against performance goals established by the Compensation Committee.

        Each performance unit will have a grant date value of $100. The amount of cash payable at the end of the performance period will be determined by multiplying the number of performance units by the total shareholder return modifier ("TSR Modifier"). The TSR Modifier is determined as follows:

        Total shareholder return for the Company and each of the peer companies is determined by dividing (i) the end average stock price plus dividends minus the start average stock price by (ii) the start average stock price, with the average stock price being the average closing stock price for the 30 trading days immediately preceding the beginning of each of the performance period and the maturity date, as reported on the stock exchange on which such shares are listed. We believe utilizing an incentive award such as the performance units, based on total shareholder return, is an appropriate vehicle to align the interests of our officers who are entitled to receive such an award with the interests of our shareholders.

        Each recipient will forfeit his or her performance units if the recipient's employment with us is terminated by the Company for any reason or if the recipient resigns (in either case, other than for death or disability). If the employment is terminated due to death or disability, the recipient is entitled to receive a pro-rated performance unit. Generally, grants of performance units will be made in the first quarter of each year, when our results of operations for the previous year have generally been determined and when our Compensation Committee is normally meeting to discuss short-term incentive payouts based on the prior-year results.

        In addition to base salary increases and short-term incentive target increases described previously, FWC also proposed increasing long-term incentive targets as a percentage of base pay for Mr. Foutch to 500%, Mr. Schuyler to 300%, Mr. Buterbaugh to 300% and Mr. Minton to 220% for 2013. The decision was made after reviewing market median data for total compensation for executives in our peer group. The Compensation Committee and the board of directors approved the recommendation.

Other Benefits

•

Health and welfare benefits.



°

Our named executive officers are eligible to participate in all of our employee health and welfare benefit plans on the same basis as other employees (subject to applicable law) to meet their health and welfare needs. These plans include medical, vision and dental insurance, as well as medical and dependent care flexible spending accounts. These benefits are provided in order to ensure that we are able to competitively attract and retain officers and other employees. This is a fixed component of compensation, and these benefits are provided on a non-discriminatory basis to all employees.



•

Retirement benefits.



°

Our named executive officers also participate in our 401(k) defined contribution plan on the same basis as our other employees. The plan allows eligible employees to make tax-deferred contributions up to 100% of their annual compensation, not to exceed annual limits established by the federal government. We make matching contributions of up to 6% of an employee's compensation and may make additional discretionary contributions in the form of cash.

Perquisites.



°

We believe that the total mix of compensation and benefits provided to our executive officers is currently competitive and, therefore, perquisites do not play a significant role in our executive officers' total compensation. Nevertheless, Laredo provides limited perquisites and benefits to its officers, including reimbursement for cell phone charges and monthly dues at a downtown lunch/dinner club.

As described in detail in "Transactions with Related Persons—Other Related-Party Transactions," our board of directors adopted an aircraft use policy for Mr. Foutch, whereby his personally owned aircraft can be used for business travel, subject to certain conditions. Under this policy, we reimbursed or paid for certain operational expenses, such as the training and certification expenses of Mr. Foutch and the cost of aircraft safety and mechanical inspections. These paid-for expenses, however, represent only a partial refund of the total costs and expenses of operating the aircraft. Effective January 1, 2013, we entered into an aircraft lease with an entity owned by Mr. Foutch and our board of directors adopted a revised aircraft use policy. Under the new arrangement, we pay an hourly rate for the use of the aircraft owned by such entity and also pay for all operating costs associated with our use of the aircraft, as well as expenses related to the flight crew and other expenses. For further details, see the "Summary compensation table" below and "Transactions with Related Persons—Other Related-Party Transactions."

Employment, Severance or Change in Control Agreements

        We do not currently maintain any employment agreements. On November 9, 2011, the Company adopted the Laredo Petroleum Holdings, Inc. Change in Control Executive Severance Plan, which provides severance payments and benefits to our named executive officers and eligible persons with the title of vice president and above, as determined by our Compensation Committee. The policy provides an eligible participant with a lump sum cash severance payment and continued health benefits in the event that the participant experiences a qualifying termination event within the one-year period following the occurrence of a qualifying change in control event ("double trigger"). In the event that an eligible executive's employment is terminated without cause by the employer or for good reason by the executive within the one-year period following the occurrence of a change in control, the executive would become entitled to receive 100% (in the case of our Chief Executive Officer, 300%, and in the case of our other named executive officers, 200%) of the executive's base salary and 100% of the executive's target bonus. In addition, the executive would receive Company-paid COBRA continuation coverage for up to twelve months following the date of termination. The policy contains a modified cutback provision whereby payments payable to an executive may be reduced if doing so would put the executive in a more advantageous after-tax provision than if payments were not reduced and the executive became subject to excise taxes under Section 4999 of the Internal Revenue Code and loss of deduction under Section 280G of the Internal Revenue Code. These severance levels are comparable to those utilized by our peer group.

        We believe that our Change in Control Executive Severance Plan, including its requirement of a "double trigger", provides suitable incentive for our officers to remain with the Company in the event of a potential change in control through the consummation of any such transaction. We further believe such an incentive is to the benefit of our stockholders as well as any potential purchaser in connection with a change in control transaction, as it helps to assure the continued operation and seamless transition of the Company prior to and through the conclusion of any such transaction. The compensation "multipliers" among the different categories of our officers were established based upon information provided by FWC regarding both our peer group and the industry in general.

Other Matters

Risk assessment

        The Compensation Committee and management have reviewed our compensation policies as generally applicable to our employees and believe that our policies do not encourage excessive and unnecessary risk-taking, and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on us.

        Our compensation philosophy and culture support the use of base salary, cash bonuses and long-term incentive equity compensation that are generally uniform in design and operation throughout our organization and with all levels of employees. In addition, the following specific factors, in particular, reduce the likelihood of excessive risk-taking:

•

Our overall compensation levels are competitive with the market; and



•

Our compensation mix is balanced among (i) fixed components like base salary and benefits, (ii) capped cash bonuses and (iii) long-term incentive equity that reward our employees based on long-term overall financial performance, operational measures and individual performance.

        Furthermore, prior to our corporate reorganization we provided our officers the opportunity to invest in our equity, which all of our named executive officers who were with the Company at the time did, and now we provide our officers with the opportunity to be awarded long-term incentive equity that continues to align their interests with those of our stockholders.

        In summary, because the Compensation Committee focuses on the Company's performance, with only some consideration given to the specific individual performance of the employee when making compensation decisions, we believe our historical compensation programs did not, and our current compensation programs do not, encourage excessive and unnecessary risk taking by executive officers (or other employees). These programs were and are designed to encourage employees to remain focused on both our short- and long-term operational and financial goals. We set performance goals that we believe are reasonable in light of our past performance and market conditions. The Compensation Committee will continue to monitor all levels of compensation to attempt to ensure that no element of compensation encourages excessive and unnecessary risk-taking.

Equity ownership guidelines

        The Compensation Committee recommended and the board of directors approved stock ownership guidelines for directors and the executive management team in order to further align the interest of our directors and officers with those of our stockholders. Effective as of the consummation of our initial public offering, individuals have three years to reach the following stock ownership guidelines (as a multiple of base salary): (i) Chief Executive Officer: 5x, (ii) President and Chief Operating Officer: 3x, (iii) Executive and Senior Vice President: 2x, (iv) Vice President: 1x and (v) directors: $400,000 worth of Company stock. Stock actually owned, as well as stock awarded under restricted stock awards, is included for purposes of satisfying these guidelines. No stock potentially exercisable under stock options is included. As of March 20, 2012, each of the named executive officers, as well as Ambassador Rooney, Mr. Parker, Ms. Pierce and Mr. Wolf, have achieved the stock ownership guidelines.

Tax and accounting implications

        Internal Revenue Code Section 162(m) denies a federal income tax deduction for certain compensation in excess of $1 million per year paid to the chief executive officer and the three other most highly-paid executive officers (other than the chief executive officer and chief financial officer) of a publicly-traded corporation. Certain types of compensation, including compensation based on performance criteria that are approved in advance by stockholders, are excluded from the deduction

33

limit. In addition, "grandfather" provisions may apply to certain compensation arrangements, including the 2011 Plan, that were entered into by a corporation before it was publicly held. In view of these grandfather provisions, we believe that Section 162(m) of the Internal Revenue Code will not limit our tax deductions for executive compensation for the first three fiscal years following the consummation of our initial public offering. Going forward, our policy is to qualify compensation paid to our executive officers for deductibility for federal income tax purposes to the extent feasible. However, to retain highly skilled executives and remain competitive with other employers, the Compensation Committee will have the right to authorize compensation that would not otherwise be deductible under Section 162(m).

Policies against hedging and pledging stock

        Under the terms of our Insider Trading Policy that is applicable to our named executive officers, such persons are prohibited from engaging in hedging transactions that are designed to hedge or offset a decrease in market value of such person's common stock in the Company. We prohibit such conduct because to allow such activity the officer could then no longer be exposed to the full risks of ownership and may no longer have the same objectives as the Company's other stockholders.

        In addition, our named executive officers may not hold their Company securities in a margin account and may not, without prior approval, pledge Company securities as collateral for any other loan. The only exception to the prohibition on pledging securities may exist in the case of a non-margin loan where the officer was clearly able to demonstrate the financial ability to repay the loan without resort to the pledged securities, and only if such pledge was pre-approved by our General Counsel.

Table of Contents

        Eligibility.    Our employees, consultants and directors and those of our affiliated companies, as well as those whom we reasonably expect to become our employees, consultants and directors or those of our affiliated companies are eligible for awards, provided that incentive stock options may be granted only to employees. A written agreement between us and each participant will evidence the terms of each award granted under the 2011 Plan.

        Shares subject to the 2011 Plan.    The shares that may be issued pursuant to awards will be our common stock, $0.01 par value per share, and the maximum aggregate amount of common stock which may be issued upon exercise of all awards under the 2011 Plan, including incentive stock options, may not exceed 10 million shares, subject to adjustment to reflect certain corporate transactions or changes in our capital structure. In addition, the maximum number of shares with respect to which stock options and/or stock appreciation rights may be granted to any participant in any one year period is limited to 10 million shares, the maximum number of shares with respect to which incentive stock options may be granted under the 2011 Plan may not exceed 10 million shares, no more than 10 million shares may be earned in respect of performance units denominated in shares granted to any single participant for a single calendar year during a performance period, or in the event that the performance unit is paid in cash, other securities, other awards or other property, no more than the fair market value of 10 million shares of common stock on the last day of the performance period to which the award related, and the maximum amount that can be paid to any single participant in one calendar year pursuant to a cash bonus award is $5 million, in each case, subject to adjustment for certain corporate events.

        If any award under the 2011 Plan expires or otherwise terminates, in whole or in part, without having been exercised in full, the common stock withheld from issuance under that award will become available for future issuance under the 2011 Plan. If shares issued under the 2011 Plan are reacquired by us pursuant to the terms of any forfeiture provision, those shares will become available for future awards under the 2011 Plan. Awards that can only be settled in cash will not be treated as shares of common stock granted for purposes of the 2011 Plan.

        Administration.    Our board of directors, or a committee of members of our board of directors appointed by our board of directors, may administer the 2011 Plan, and that administrator is referred to in this summary as the "administrator." Among other responsibilities, the administrator selects participants from among the eligible individuals, determines the number of shares of common stock that will be subject to each award and determines the terms and conditions of each award, including exercise price, methods of payment and vesting schedules. Our board of directors may amend or terminate the 2011 Plan at any time. Amendments will not be effective without stockholder approval if stockholder approval is required by applicable law or stock exchange requirements.

        Adjustments in capitalization.    Subject to the terms of an award agreement, if there is a specified type of change in our common stock, such as extraordinary cash dividends, stock splits, reverse stock splits, recapitalizations, reorganizations, mergers, consolidations, combinations, exchanges or other relevant changes in capitalization, appropriate equitable adjustments or substitutions will be made to the various limits under, and the share terms of, the 2011 Plan and the awards granted thereunder, including the maximum number of shares reserved under the 2011 Plan, the maximum number of shares with respect to which any participant may be granted awards and the number, price or kind of shares of common stock or other consideration subject to awards to the extent necessary to preserve the economic intent of the award. In addition, subject to the terms of an award agreement, in the event of certain mergers, the sale of all or substantially all of our assets, our reorganization or liquidation, or our agreement to enter into any such transaction, the administrator may cancel outstanding awards and cause participants to receive, in cash, stock or a combination thereof, the value of the awards.

        Change in control.    In the event of a change in control, all options and stock appreciation rights subject to an award will become fully vested and immediately exercisable and any restricted period

imposed upon restricted awards will expire immediately (including a waiver of applicable performance goals). Accelerated exercisability and lapse of restricted periods will, to the extent practicable, occur at a time which allows participants to participate in the change in control. In the event of a change of control, all incomplete performance periods will end, the administrator will determine the extent to which performance goals have been met, and such awards will be paid based upon the degree to which performance goals were achieved.

        Nontransferability.    In general, each award granted under the 2011 Plan may be exercisable only by a participant during the participant's lifetime or, if permissible under applicable law, by the participant's legal guardian or representative. Except in very limited circumstances, no award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a participant other than by will or by the laws of descent and distribution, and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance will be void and unenforceable against us. However, the designation of a beneficiary will not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance.

        Section 409A.    The provisions of the 2011 Plan and the awards granted under the 2011 Plan are intended to comply with or be exempt from the provisions of Section 409A of the Internal Revenue Code and the regulations thereunder so as to avoid the imposition of an additional tax under Section 409A of the Internal Revenue Code.

Potential Payments upon Termination or Change in Control

Severance

        As described above, we do not maintain individual employment agreements. The Company has adopted the Laredo Petroleum Holdings, Inc. Change in Control Executive Severance Plan, which provides severance payments and benefits to our named executive officers and eligible persons with the title of vice president and above, as determined by our Compensation Committee. The policy provides an eligible participant with a lump sum cash severance payment and continued health benefits in the event that the participant experiences a qualifying termination within the one-year period following the occurrence of a qualifying change in control event. In the event that an eligible executive's employment is terminated without cause by the employer or for good reason by the employee within the one-year period following the occurrence of a change in control, the executive would become entitled to receive 100% (in the case of our Chief Executive Officer, 300%, and in the case of our other named executive officers, 200%) of the executive's base salary and 100% of the executive's target bonus. In addition, the executive would receive company paid COBRA continuation coverage for up to twelve months following the date of termination. The policy contains a modified cutback provision whereby payments payable to an executive may be reduced if doing so would put the executive in a more advantageous after-tax provision than if payments were not reduced and the executive became subject to excise taxes.

Table of Contents

In order to be eligible for severance benefits under the policy, our named executive officers have executed a confidentiality, non-disparagement and non-solicitation agreement.

Restricted Stock

        Each of the named executive officers who was with the Company prior to our corporate reorganization was awarded restricted units by Laredo LLC and the unvested restricted units were exchanged into shares of restricted stock in connection with the corporate reorganization and initial public offering in 2011. The terms of the restricted stock awards following the exchange are described below.

        The restricted stock may be affected by a named executive officer's termination of employment or the occurrence of certain corporate events. In the event of the termination of a named executive officer's employment by the Company, with or without cause, or the named executive officer's resignation for any reason, the named executive officer will forfeit all restricted stock to us.

        If the named executive officer's employment with the Company is terminated upon the death of the named executive officer or because the named executive officer is determined to be disabled by the board of directors, then all of his restricted stock will automatically vest. A named executive officer will be considered to have incurred a "disability" in the event of the officer's inability to perform, even with reasonable accommodation, on a full-time basis the employment duties and responsibilities due to accident, physical or mental illness, or other circumstance; provided, however, that such inability continues for a period exceeding 180 days during any 12-month period.

        In the event of a change of control, all restricted stock will become fully vested as of the date of the change of control, provided that the named executive officer remains employed by the Company through the date of such change of control. For purposes of these restricted stock awards, a "change of control" generally means: (i) any person acquires beneficial ownership of our securities representing 40% or more of the combined voting power of our outstanding securities (provided, however, that if the surviving entity becomes a subsidiary of another entity, then the outstanding securities shall be deemed to refer to the outstanding securities of the parent entity), (ii) a majority of the members of the board of directors who were directors as of the date of the corporate reorganization no longer serve as directors; or (iii) the consummation of a merger or consolidation of our company with any other entity, other than a merger or consolidation which would result in our voting securities outstanding immediately prior thereto continuing to represent more than 40% of the combined voting power of our voting securities outstanding immediately after such merger or consolidation.

Stock Options

        Stock options may be affected by a named executive officer's termination of employment or the occurrence of certain corporate events. The unvested portion of a stock option shall expire upon termination of employment, and the vested portion of a stock option shall remain exercisable for (i) one year following termination of employment by reason of the holder's death or disability, but not later than the expiration of the option period, or (ii) ninety (90) days following termination of employment for any reason other than the holder's death or disability, and other than the holder's termination of employment for cause. Both the unvested and the vested but unexercised portion of a stock option shall expire upon the termination of the option holder's employment or service by the Company for cause.

        In the event of a change of control (which for these purposes is the same as described above), provided that the named executive officer remains employed by the Company through the date of such change of control, all stock options will become fully vested and exercisable with respect to all shares of common stock covered thereby as of the date of the change of control.

Performance Unit Awards

        Performance unit awards may be affected by a named executive officer's termination of employment or the occurrence of certain corporate events. If the executive's employment with the Company is terminated by the Company for any reason, with or without cause, or the executive resigns (in either case, other than by reason of death or disability) prior to the maturity date of the performance unit award, then no amount shall be paid in respect of the award. If, prior to the maturity date, the executive's employment with the Company terminates either by reason of death or or because the executive is determined by the board of directors or the Compensation Committee to be subject to a disability, then the executive shall be eligible to receive a pro-rated performance unit award, taking into account the time that the executive was employed during the performance period prior to the date of such termination.

        In the event of a change of control (which for these purposes is the same as described above), provided that the named executive officer remains employed by the Company through the date of such change of control, the "performance periods" in effect on the date the change of control occurs shall end on such date, and either the board of directors or the Compensation Committee shall determine the extent to which the performance goals with respect to each such performance period have been met, based upon such audited or unaudited financial information or other information then available as it deems relevant. The board of directors or Compensation Committee shall then cause each holder of performance unit awards to receive partial or full payment of such awards for each performance period, based on the board of directors' or Compensation Committee's determination of the degree of attainment of the performance goals or that the applicable "target" levels of performance have been attained or on such other basis determined by the board of directors or Compensation Committee.

Potential Payments upon Termination or Change in Control Table for Fiscal Year 2012

        The information set forth in the table below is based on the assumption that the applicable triggering event under the Laredo Petroleum Holdings, Inc. Change in Control Executive Severance Plan or the applicable restricted stock, stock option or performance unit award agreement to which each named officer was a party occurred on December 31, 2012, the last business day of fiscal year 2012. Accordingly, the information reported in the table indicates the amount of cash severance and benefits that would be payable, and the value of restricted stock, stock options and performance units that would vest or become exercisable, by reason of a termination under the circumstances described above, or upon a change in control, and is our best estimation of our obligations to each named executive officer and will only be determinable with any certainty upon the occurrence of the applicable event. For purposes of determining the value of the accelerated vesting of restricted stock awards, the fair market value per share of our common stock was $18.16 on December 31, 2012. For purposes of determining the value of the accelerated vesting of stock options, we utilized the Black-Scholes option pricing model at grant date. For purposes of determining the value of the accelerated vesting of the performance units, we utilized the December 31, 2012 fair value computed in accordance with FASB ASC Topic 718.

Securities Authorized for Issuance under 2011 Plan

        At December 31, 2012, a total of 10 million shares of common stock were authorized for issuance under the 2011 Plan. In the table below, we describe certain information about these shares and the 2011 Plan which provides for their authorization and issuance. You can find a description of the 2011 Plan under "—Laredo Petroleum Holdings, Inc. 2011 Omnibus Equity Incentive Plan."

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        No member of the Compensation Committee has been at any time an employee of Laredo. None of the Company's executive officers serve on the board of directors or compensation committee of a company that has an executive officer that serves on the Company's board of directors or Compensation Committee. No member of the Company's board of directors is an executive officer of a company in which one of the Company's executive officers serves as a member of the board of directors or compensation committee of that company.

AUDIT COMMITTEE REPORT

        The Company has determined that: (i) Messrs. Segner, Parker, Wolf and Scoggins are independent, as defined in Section 10A of the Exchange Act and under the standards set forth by the NYSE; (ii) Mr. Levy was permitted to serve as a member of the Audit Committee for a period of up to one year following the completion of our initial public offering; and (iii) all current Audit Committee members are financially literate. In addition, Messrs. Segner and Wolf each qualify as an audit committee financial expert under the applicable rules promulgated pursuant to the Exchange Act.

        Until the election of Dr. Scoggins to the Audit Committee in place of Mr. Levy in November 2012, the Company relied on the phase-in rules of the SEC and NYSE with respect to the independence of the Audit Committee. These rules permit an audit committee that has one member that is independent upon the effectiveness of the registration, a majority of members that are independent within 90 days thereafter and all members that are independent within one year thereafter. The Company does not believe its reliance on these phase-in rules materially adversely affected the Audit Committee's ability to act independently or to satisfy the other requirements of Rule 10A-3(d).

Table of Contents

        During the last fiscal year, and earlier this year in preparation for the filing with the SEC of the Company's Annual Report on Form 10-K for the year ended December 31, 2012, the Audit Committee:

•

reviewed and discussed the Company's audited consolidated financial statements as of and for the year ended December 31, 2012 with management and with the independent registered public accountants;



•

considered the adequacy of the Company's internal controls and the quality of its financial reporting, and discussed these matters with management and with the independent registered public accountants;



•

reviewed and discussed with the independent registered public accountants (i) their judgments as to the quality of the Company's accounting policies, (ii) the written disclosures and letter from the independent registered public accountants required by Public Company Accounting Oversight Board Independence Rules, and the independent registered public accountants' independence, and (iii) the matters required to be discussed by the Public Company Accounting Oversight Board's AU Section 380, Communication with Audit Committees, by the Auditing Standards Board of the American Institute of Certified Public Accountants;



•

discussed with management and with the independent registered public accountants the process by which the Company's Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer make the certifications required by the SEC in connection with the filing with the SEC of the Company's periodic reports, including reports on Forms 10-K and 10-Q;



•

pre-approved all auditing services and non-audit services to be performed for the Company by the independent registered public accountants as required by the applicable rules promulgated pursuant to the Exchange Act, considered whether the rendering of non-audit services was compatible with maintaining Grant Thornton LLP's independence, and concluded that Grant Thornton LLP's independence was not compromised by the provision of such services (details regarding the fees paid to Grant Thornton LLP in fiscal year 2012 for audit services, tax services and all other services, are set forth in "Audit and Other Fees" below); and



•

based on the reviews and discussions referred to above, recommended to the board of directors that the audited consolidated financial statements referred to above be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012.

        As recommended by the NYSE's corporate governance rules, the Audit Committee also considered whether, to assure continuing auditor independence, it would be advisable to regularly rotate the audit firm itself. The Audit Committee has concluded that the current benefits to the Company from continued retention of Grant Thornton LLP warrant retaining the firm at this time. The Audit Committee will, however, continue to review this issue on an annual basis.

        Notwithstanding the foregoing actions and the responsibilities set forth in the Audit Committee Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company's consolidated financial statements are complete and accurate and in accordance with generally accepted accounting principles. Management is responsible for the Company's financial reporting process, including its system of internal controls, and for the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States. The independent registered public accountants are responsible for expressing an opinion on those financial statements. Audit Committee members are not employees of the Company or accountants or auditors by profession. Therefore, the Audit Committee has relied, without independent verification, on management's representation that the consolidated financial statements have been prepared with integrity and objectivity and in conformity with accounting principles generally accepted in the United States and on the representations of the independent registered public accountants included in their report on the Company's consolidated financial statements.

Table of Contents

        The Audit Committee meets regularly with management and the independent auditors, including private discussions with the independent registered public accountants, and receives the communications described above. The Audit Committee has also established procedures for (i) the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters, and (ii) the confidential, anonymous submission by the Company's employees of concerns regarding questionable accounting or auditing matters. However, this oversight does not provide us with an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or policies, or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, our considerations and discussions with management and the independent registered public accountants do not assure that the Company's consolidated financial statements are presented in accordance with generally accepted accounting principles or that the audit of the Company's consolidated financial statements has been carried out in accordance with generally accepted auditing standards.

        The information contained in this Audit Committee Report and references in this Proxy Statement to the independence of the Audit Committee members shall not be deemed to be "soliciting material" or to be "filed" with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent that the Company specifically incorporates such information by reference in such filing.

CORPORATE GOVERNANCE

Corporate Governance Guidelines

        The board of directors believes that its fundamental responsibility is to promote the best interests of the Company and its stockholders by overseeing the management of the Company's business and affairs. Directors must exercise their business judgment and act in what they reasonably believe to be the best interests of the Company and its stockholders. The board of directors is elected by the stockholders to oversee management and to assure that the long-term interests of the stockholders are being served. Directors must fulfill their responsibilities consistent with their fiduciary duties to the stockholders and in compliance with applicable laws and regulations.

        The board of directors believes that sound governance practices and policies provide an important framework to assist it in fulfilling its duty to the Company's stockholders. The Company's Corporate Governance Guidelines cover the following principal subjects:

•

Board of Directors Composition and Selection; Director Qualifications

Board of directors size

Table of Contents

        The NYSE has adopted rules that require listed companies to adopt governance guidelines covering certain matters. The Company believes that the Corporate Governance Guidelines comply with the NYSE rules.

Code of Conduct and Business Ethics

        The board of directors has adopted a Code of Conduct and Business Ethics applicable to our employees, directors and officers and a Code of Ethics for Senior Financial Officers, in accordance with applicable U.S. federal securities laws and the corporate governance rules of the NYSE. Any waiver of these codes may be made only by our board of directors and will be promptly disclosed as required by applicable U.S. federal securities laws and the corporate governance rules of the NYSE. A copy of the Code of Conduct and Business Ethics and Code of Ethics for Senior Financial Officers is available on our website at www.laredopetro.com.

Board of Directors Leadership

        Mr. Foutch is Laredo's founder and has served as Laredo's Chairman and Chief Executive Officer since its inception. He also served as Laredo's President from October 2006 to July 2008.

        The board of directors believes the combined role of Chairman and Chief Executive Officer promotes unified leadership and direction for the Company, which allows for a single, clear focus for management to execute the Company's strategy and business plans. As Chief Executive Officer, the Chairman is best suited to ensure that critical business issues are brought before the board of directors, which enhances the board of director's ability to develop and implement business strategies.

        To ensure a strong and independent board of directors, all directors of the Company, other than Mr. Foutch and Mr. Schuyler, are independent within the meaning of the NYSE listing standards currently in effect. Our Corporate Governance Guidelines provide that non-management directors shall meet in regular executive session without management present, and that the Chairman of the Audit Committee, Mr. Segner, shall act as the Chairman of such meetings.

        Because Warburg Pincus owns a majority of the Company's outstanding common stock, the Company is a "controlled company" as that term is set forth in the NYSE Listed Company Manual. Under the NYSE rules, a "controlled company" may elect not to comply with certain NYSE corporate governance requirements, including: (i) the requirement that a majority of the Company's board of directors consist of independent directors, (ii) the requirement that the Company's Nominating and Corporate Governance Committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities, and (iii) the requirement that the Company's Compensation Committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities. While these requirements will not apply to the Company as long as it remains a "controlled company," the Company's board of directors nonetheless consists of a majority of independent directors and its Nominating and Corporate Governance Committee and Compensation Committee consist entirely of independent directors within the meaning of the NYSE listing standards currently in effect. The Nominating and Corporate Governance Committee and the Compensation Committee each have a written charter addressing such committee's purpose and responsibilities in accordance with NYSE listing standards.

        The board of directors currently consists of a single class of directors each serving one-year terms. After Warburg Pincus no longer beneficially owns more than 50% of the Company's issued and outstanding common stock, the Company's board of directors will be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three-year terms, and such directors being removable only for "cause."

Communications with the Board of Directors

        Stockholders or other interested parties can contact any director, any committee of the board of directors, or the Company's non-management directors as a group, by writing to them at Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119. Comments or complaints relating to the Company's accounting, internal accounting controls or auditing matters will also be referred to members of the Audit Committee. All such communications will be forwarded to the appropriate member(s) of the board of directors.

Director Independence

        The board of directors annually reviews and determines the independence of each director. In making its determination, the board of directors carefully considers all facts and circumstances it deems relevant to the determination. Members of the board of directors have an affirmative obligation to promptly inform the Company's General Counsel of changes in their circumstances or any transactions or relationships that may impact their designation by the board of directors as "independent."

        The board of directors has assessed the independence of each non-employee director under the Company's guidelines and the independence standards of the NYSE. The board of directors affirmatively determined that all eight of the non-employee directors (Messrs. Kagan, Levy, Parker, Rooney, Segner and Wolf, Dr. Scoggins and Ms. Pierce) are independent under the Company's guidelines and independence standards of the NYSE.

        In connection with its assessment of the independence of each non-employee director, the board of directors also determined that Messrs. Segner, Parker, and Wolf and Dr. Scoggins meet the additional independence standards of the NYSE and SEC applicable to members of the Audit Committee. Those standards require that the director not be an affiliate of the Company and that the director not receive from the Company, directly or indirectly, any consulting, advisory or other compensatory fees except for fees for services as a director. During his tenure on the Audit Committee prior to November 28, 2012, the board of directors also determined that Mr. Levy did not meet the additional independence standards of the SEC applicable to members of the Audit Committee because he is an affiliate of the Company due to his association with Warburg Pincus. However, under applicable SEC phase-in requirements, Mr. Levy was permitted to serve as a member of the Audit Committee for a period of up to one year following the completion of the Company's initial public offering.

Executive Sessions of the Board of Directors

        Our independent directors meet regularly in executive session without management to review the performance of management and our Company and any related matters. The Chairman of our Audit Committee, Mr. Segner, serves as the Chairman and lead independent director of such meetings. Generally, executive sessions are held in conjunction with regularly scheduled meetings of our board of directors. We expect our board of directors to have at least four executive sessions each year.

Financial Literacy of Audit Committee and Designation of Financial Experts

        The board of directors evaluated each of the members of the Audit Committee for financial literacy and the attributes of a financial expert on November 28, 2012. The board of directors determined that each of the Audit Committee members is financially literate and that Messrs. Segner and Wolf are Audit Committee financial experts as defined by the SEC.

Oversight of Risk Management

        The board of directors oversees an enterprise-wide approach to risk management, designed to support the achievement of the Company's objectives and to maintain stockholder value. The Audit

53

---

Table of Contents

Committee is primarily responsible for overseeing the Company's exposure to financial risk and reviewing the steps the Company's management has taken to monitor and control such exposure. The Audit Committee meets at least four times per year, in addition to periodic meetings with management and internal and independent auditors to accomplish its purpose. Additionally, each of the committees of the board of directors considers the risks within its area of responsibilities. We believe that the leadership structure of our board of directors supports its effective oversight of the Company's risk management.

Attendance at Annual Meetings

        The board of directors encourages all directors to attend the annual meetings of stockholders, if practicable. We anticipate that all of our directors will attend the Annual Meeting.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

        The following table sets forth certain information regarding the beneficial ownership of common stock as of March 20, 2013 by (i) beneficial owners of five percent or more of the Company's common stock, (ii) each director of the Company, (iii) each named executive officer of the Company and (iv) all of the Company's directors and executive officers as a group. Unless otherwise noted, the mailing address of each person or entity named below is c/o Laredo Petroleum Holdings, Inc., 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        The executive officers and directors of the Company and persons who own more than 10% of the Company's common stock are required to file reports with the SEC, disclosing the amount and nature of their beneficial ownership in common stock, as well as changes in that ownership. Based solely on our review of reports and written representations that the Company has received, the Company believes that all required reports were timely filed during 2012, with the following exceptions: Dr. Scoggins and Messrs. Parker, Kagan, Levy and Rooney, and Ms. Pierce each chose to receive 528 shares of restricted stock in lieu of cash in payment of their director fees at the November 28, 2012 quarterly meeting of the board. The Form 4 covering the shares of restricted stock issued to each of these directors was inadvertently filed late on December 13, 2012.

TRANSACTIONS WITH RELATED PERSONS

Procedures for Review, Approval and Ratification of Related Person Transactions

        A "Related-Party Transaction" is a transaction, arrangement or relationship in which the Company or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest. A "Related Person" means:

•

any person who is, or at any time during the applicable period was, one of the Company's executive officers or one of its directors;



•

any person who is known by the Company to be the beneficial owner of more than 5.0% of the Company's common stock;



•

any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of a director, executive officer or a beneficial owner of more than 5.0% of the Company's common stock; and



•

any entity in which any of the foregoing persons (i) has direct or indirect control, (ii) is a partner or principal or in a similar position, (iii) has a 10.0% or greater beneficial ownership interest or (iv) is employed if (a) the person is directly involved in the negotiation of the Related-Party Transaction or will share or have primary responsibility for such transaction or (b) the person's compensation from the entity is directly tied to such transaction.

        The board of directors has determined that the Audit Committee is best suited to review and approve Related-Party Transactions, although the board of directors may instead determine that a particular Related-Party Transaction should be reviewed and approved by a majority of disinterested directors. No member of the Audit Committee shall participate in the review or approval of any Related-Party Transaction with respect to which such member is a Related Person. In reviewing and approving any Related-Party Transaction, the Audit Committee shall:

•

Satisfy itself that it has been fully informed as to the material facts of the Related Person's relationship and interest and as to the material facts of the proposed Related-Party Transaction;



•

Take into account the extent of the Related Person's interest in the Related-Party Transaction; and



•

Determine that the Related-Party Transaction is fair to the Company and that the Related-Party Transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances.

        At each Audit Committee meeting, management shall recommend any Related-Party Transactions, if applicable, to be entered into by the Company. After review, the Audit Committee shall approve or

57

---

Table of Contents

disapprove such transactions and at each subsequently scheduled meeting, management shall update the Audit Committee as to any material change to those proposed transactions. The Audit Committee shall establish such guidelines as it determines are necessary or appropriate for management to follow in its dealings with Related Persons in Related-Party Transactions.

        If management becomes aware of a proposed Related-Party Transaction or an existing Related-Party Transaction that has not been pre-approved by the Audit Committee, management shall promptly notify the Chairman of the Audit Committee and such transactions shall be submitted to the Audit Committee for their review, consideration and determination of whether to approve or ratify, as applicable, such transaction if the Audit Committee determines it is fair to the Company. If management, in consultation with the Company's Chief Executive Officer or Chief Financial Officer, determines that it is not practicable to wait until the next Audit Committee meeting, the Chairman of the Audit Committee has the delegated authority during the period between Audit Committee meetings, to review, consider and determine whether any such transaction is fair to the Company and whether the transaction should be approved, or ratified, as the case may be. The Chairman of the Audit Committee shall report to the Audit Committee any transactions reviewed by him pursuant to this delegated authority at the next Audit Committee meeting.

        Additional information relating to the Company's policies regarding Related-Party Transactions is set forth in the "Policy Statement Regarding Related-Party Transactions" that is posted on the Company's website at www.laredopetro.com.

        Since December 31, 2011, Laredo has participated in the transactions set forth below, which may be considered Related-Party Transactions as defined above:

Gas Gathering and Processing Arrangement with Targa

        The Company has a gas gathering and processing arrangement with affiliates of Targa Resources, Inc. ("Targa"). Warburg Pincus Private Equity IX, L.P., a majority stockholder in the Company, and other Warburg Pincus affiliates hold investment interests in Targa. Mr. Kagan, one of our directors, is on the board of directors of affiliates of Targa and Targa Resource Partners, L.P. Laredo's net oil and gas sales to Targa were approximately $71.9 million for the year ended December 31, 2012.

Registration Rights

        On December 20, 2011, in connection with the closing of its initial public offering, the Company entered into a registration rights agreement (the "Registration Rights Agreement") with affiliates of Warburg Pincus and the other former unitholders of Laredo LLC (together with Warburg Pincus, the "Holders"). The Registration Rights Agreement requires the Company to file, within 30 days of receipt of a demand notice issued by Warburg Pincus, a registration statement with the SEC permitting the public offering of registrable securities. In addition, the Registration Rights Agreement grants the Holders the right to join the Company, or "piggyback", in certain circumstances, if the Company is selling its common stock in an offering at any time after its initial public offering. The Registration Rights Agreement also includes customary provisions dealing with indemnification, contribution and allocation of expenses.

Other Related-Party Transactions

        Prior to January 1, 2013, we had an aircraft use policy in place, adopted by our board of directors, pursuant to which an aircraft owned by Lariat Ranch, LLC ("Lariat"), an entity controlled by our Chairman and Chief Executive Officer Randy A. Foutch, could be used for Company business travel, subject to certain conditions. The expenses covered by us under the policy consisted of the salary of the co-pilot and his out-of-pocket expenses on business trips, the training and certification expenses of

58

Table of Contents

Mr. Foutch (who is a fully qualified pilot) and the co-pilot, and the cost of aircraft safety and mechanical inspections. In addition, we reimbursed Mr. Foutch for the use of this aircraft for Company business in an amount equal to the cost of a first class commercial airline ticket to such destination or the cost of a charter flight if commercial flights are not available to such destination. Through December 31, 2012, Laredo incurred approximately $231,178 in expenses in 2012 for business trips pursuant to this policy. These payments represented only a partial refund of the total costs and expenses of flying the aircraft, including the additional fixed costs required to be incurred under the policy, and as a result Mr. Foutch incurred a loss each year on Laredo's business use of the aircraft. All amounts reimbursed to Mr. Foutch were approved by our Chief Financial Officer in accordance with the board of directors' approved policy.

        On January 1, 2013, we entered into a Non-Exclusive Aircraft Lease Agreement (the "Aircraft Lease") with Lariat for a term of one year, automatically renewable for subsequent one-year terms subject to the parties' termination rights. Under the Aircraft Lease, we lease the airplane owned by Lariat from Lariat at a rate of $1,900 per flight hour, subject to quarterly redetermination by the parties, and are also responsible for all operating costs associated with our use of the aircraft, including flight crew costs and airport charges. In connection with the Aircraft Lease, our board of directors adopted a revised aircraft use policy, which replaces the previous aircraft use policy. The expenses covered by us under the revised aircraft policy are the salaries of two pilots (excluding Mr. Foutch) and expenses related to flight training and certification of Mr. Foutch and the two other pilots and other related expenses.

        Mr. Foutch and Company employees travel extensively for company business, often on short notice and to areas that have limited access to direct commercial flights, so our board of directors has determined that the use of Lariat's dedicated aircraft is an efficient, safer and cost-effective option that is beneficial to us. Although Mr. Foutch is a fully qualified pilot with a single pilot rating and has flown his aircraft solo for business while working for other companies in the past, we believe it is in our best interest to require the presence of a fully-licensed and qualified co-pilot with him, or two pilots, and certain specified safety and mechanical inspections to assure the airworthiness of the aircraft.

ITEM TWO

RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

        The Audit Committee of the board of directors has selected Grant Thornton LLP as the independent registered public accounting firm of the Company for 2013. Grant Thornton LLP has audited Laredo's consolidated financial statements since its inception in 2006.

        The board of directors is submitting the selection of Grant Thornton LLP for ratification at the Annual Meeting. The submission of this matter for approval by stockholders is not legally required, but the board of directors and the Audit Committee believe the submission provides an opportunity for stockholders through their vote to communicate with the board of directors and the Audit Committee about an important aspect of corporate governance. If the stockholders do not ratify the selection of Grant Thornton LLP, the Audit Committee will reconsider the selection of that firm as the Company's auditors.

        The Audit Committee has the sole authority and responsibility to retain, evaluate and replace the Company's auditors. The stockholders' ratification of the appointment of Grant Thornton LLP does not limit the authority of the Audit Committee to change auditors at any time.

Audit and Other Fees

        The table below sets forth the aggregate fees billed to Laredo by Grant Thornton LLP, the Company's independent registered public accounting firm, for the last two fiscal years:

        The Audit Committee Charter and its pre-approval policy require that the Audit Committee review and pre-approve the plan and scope of Grant Thornton LLP's audit, tax and other services. Laredo's Audit Committee pre-approved 100% of the services described above under the captions "Audit Fees," "Tax Fees," and "Other Fees" for the years ended December 31, 2012 and 2011.

        The Company expects that representatives of Grant Thornton LLP will be present at the Annual Meeting to respond to appropriate questions and to make a statement if they desire to do so.

        THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE SELECTION OF GRANT THORNTON LLP AS THE AUDITORS OF THE COMPANY FOR 2013.

ADVISORY VOTE ON COMPENSATION OF NAMED EXECUTIVE OFFICERS

        As required by Section 14A of the Exchange Act, which was added under the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are seeking stockholder approval on an advisory, non-binding basis of the compensation of our named executive officers as disclosed in the section of this Proxy Statement titled "Executive Compensation." In this proposal, stockholders are being asked to vote on the following advisory resolution:

        "RESOLVED, that the stockholders approve, on an advisory basis, the compensation of our named executive officers, as disclosed pursuant to Item 402(m) through (q) of Regulation S-K, including the compensation tables and the other narrative executive compensation disclosure in the Proxy Statement for our 2013 Annual Meeting of Stockholders."

        Stockholders are urged to read the "Executive Compensation" section of this Proxy Statement, which discusses in detail how our compensation policies and procedures implement our compensation philosophy, and to refer to the related executive compensation tables. The compensation of our named executive officers is based on a philosophy that ties a substantial portion of an executive's compensation to our attainment of financial and other performance measures that, our board of directors believes, promote the creation of long-term stockholder value and position our company for long-term success. As described more fully in the "Compensation Discussion and Analysis," the mix of fixed- and performance-based compensation, as well as the terms of restricted stock awards, stock options and performance units are designed to enable our company to attract and maintain top talent while, at the same time, creating a close relationship between our Company's performance and overall stockholder return and the named executive officers' compensation. Our Compensation Committee and board of directors believe that the philosophy of the program, and hence the compensation awarded to named executive officers under the current program, fulfills this objective.

        Although the vote is advisory and non-binding, our board of directors and Compensation Committee value the opinions that our stockholders express in their votes and will consider the voting results in connection with their ongoing evaluation of our compensation program.

        The affirmative "FOR" vote of a majority of the votes cast at the Annual Meeting is required to approve, on an advisory basis, the compensation of our named executive officers. Unless otherwise instructed on the proxy, properly executed proxies will be voted in favor of approving the advisory, non-binding basis of the compensation of our named executive officers.

        THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE ADVISORY RESOLUTION APPROVING THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

STOCKHOLDER PROPOSALS; IDENTIFICATION OF DIRECTOR CANDIDATES

        Stockholders who, in accordance with Rule 14a-8 under the Exchange Act, wish to present proposals for inclusion in the proxy materials to be distributed in connection with the 2014 annual meeting of stockholders must submit their proposals so that they are received at our principal executive offices no later than the close of business December 3, 2013, or, in the event the Company's 2014 annual meeting is advanced or delayed more than 30 days from the date of the Annual Meeting, within a reasonable time before the Company begins to print and mail the proxy materials for the 2014 annual meeting. As the SEC rules make clear, simply submitting a proposal does not guarantee that it will be included in the Company's proxy materials.

        In addition, stockholders who wish to introduce a proposal from the floor of the 2014 annual meeting of stockholders (outside the processes of Rule 14a-8), must submit that proposal in writing to the Company's Secretary at our principal executive offices no earlier than January 17, 2014 and no later than February 16, 2014, or, in the event the Company's 2014 annual meeting of stockholders is advanced or delayed more than 30 days from the date of the Annual Meeting, not later than the later of (i) the 90th day before the 2014 annual meeting or (ii) the 10th day following the day on which public announcement of the date of the annual meeting is first made by the Company.

        To be in proper form, a stockholder's notice must include the information required by our bylaws with respect to each proposal submitted. The Company may refuse to consider any proposal that is not timely or otherwise does not meet the requirements of our bylaws or the SEC's rules with respect to the submission of proposals. You may obtain a copy of our bylaws by submitting a request to Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119.

        Directors may be nominated by the board of directors or by stockholders in accordance with the bylaws of the Company. The Nominating and Corporate Governance Committee will review all nominees for the board of directors, including proposed nominees of stockholders, in accordance with its charter. In evaluating the suitability of candidates, the board of directors and the Nominating and Corporate Governance Committee take into account many factors, including the nominee's judgment, experience, independence, character, business acumen and such other factors as the Nominating and Corporate Governance Committee concludes are pertinent in light of the current needs of the board of directors. The board of directors believes that its membership should reflect a diversity of experience, gender, race, ethnicity and age. The Nominating and Corporate Governance Committee will select qualified nominees and review its recommendations with the board of directors, which will decide whether to invite the nominees to join the board of directors. When evaluating the suitability of an incumbent director for nomination or re-election, the board of directors and the Nominating and Corporate Governance Committee also consider the director's past performance, including attendance at meetings and participation in and contributions to the activities of the board of directors.

        The board of directors and the Nominating and Corporate Governance Committee believe they have achieved the sought after balance described above through the representation on the board of directors of members having experience in the oil and gas industry, accounting and investment analysis, among other areas. The board of directors and the Nominating and Corporate Governance Committee do not discriminate based upon race, religion, sex, national origin, age, disability, citizenship or any other legally protected status.

        In identifying potential director candidates, the board of directors and the Nominating and Corporate Governance Committee rely on any source available for the identification and recommendation of candidates, including current directors and officers. In addition, the board of directors and the Nominating and Corporate Governance Committee from time to time may engage a third-party search firm to identify or evaluate, or assist in identifying or evaluating potential candidates, for which the third party search firm will be paid a fee.

        The board of directors and Nominating and Corporate Governance Committee will also consider any nominee recommended by stockholders for election at the annual meeting of stockholders to be held in 2014 if that nomination is submitted in writing, between January 17, 2014 and February 16, 2014, or in the event the Company's 2014 annual meeting of stockholders is advanced or delayed more than 30 days from the date of the Annual Meeting, not later than the later of (i) the 90th day before the 2014 annual meeting or (ii) the 10th day following the day on which public announcement of the date of the annual meeting is first made by the Company. In the event that the number of directors to be elected to the board of directors is increased and there has been no public announcement naming all of the nominees for director or indicating the increase made by the Company at least 10 days before the last day a stockholder may deliver a notice of nomination in accordance with the preceding sentence, a stockholder's notice will be considered timely, but only with respect to nominees for any new positions created by such increase, if it is received by the Secretary at the principal executive offices of the Company not later than the close of business on the 10th day following the day on which such public announcement is first made by the Company.

        As set forth in the Company's bylaws, with respect to each such nominee, the following information must be provided to the Company with the written nomination:

a)

the nominee's name, address and age;



b)

the nominee's written consent to serve as a director if elected;



c)

the name and address of the nominating shareholder;



d)

the number of shares of each class and series of stock of the Company held by the nominating shareholder; and

all other information required to be disclosed pursuant to Regulation 14A of the Exchange Act.

        Each submission must also include a statement of the qualifications of the nominee, a notarized consent signed by the nominee evidencing a willingness to serve as a director, if elected, and a written representation and agreement that such person (i) is not and will not become a party to any voting agreement or compensation agreement that has not been disclosed to the Company or that could limit or interfere with the nominee's ability to comply with their fiduciary duties under applicable law and (ii) will comply with all of the Company's applicable corporate governance, conflict of interest, confidentiality and stock ownership and trading policies and guidelines.

        Written requests for inclusion of any stockholder proposal should be addressed to Laredo Petroleum Holdings, Inc., c/o Corporate Secretary, 15 W. Sixth Street, Suite 1800, Tulsa, Oklahoma 74119. The Company suggests that any such proposal be sent by certified mail, return receipt requested.
