CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures We carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) as of December 31, 2025. This evaluation was performed under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer of GP Natural Resource Partners LLC, our managing general partner. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that these disclosure controls and procedures were effective as of December 31, 2025 at the reasonable assurance level in producing the timely recording, processing, summary and reporting of information and in accumulation and communication of information to management to allow for timely decisions with regard to required disclosures. Management ’ s Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer of GP Natural Resource Partners LLC, our managing general partner, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2025 based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission "2013 Framework" (COSO). Based on that evaluation, as of December 31, 2025, our management concluded that our internal control over financial reporting was effective at a reasonable assurance level based on those criteria. No changes were made to our internal control over financial reporting during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Ernst & Young, LLP, the independent registered public accounting firm who audited the Partnership’s consolidated financial statements included in this Annual Report on Form 10-K, has issued a report on the Partnership’s internal control over financial reporting, which is included herein. 82 Table of Contents Report of Independent Registered Public Accounting Firm To the Partners of Natural Resource Partners L.P. Opinion on Internal Control Over Financial Reporting We have audited Natural Resource Partners L.P.’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Natural Resource Partners L.P. (the Partnership) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Natural Resource Partners L.P. as of December 31, 2025 and 2024, the related consolidated statements of comprehensive income, partners’ capital and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and our report dated February 27, 2026 expressed an unqualified opinion thereon. Basis for Opinion The Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Houston, Texas February 27, 2026 83 Table of Contents ITEM 9B.

In performing all of these functions, the Audit Committee acts only in an oversight capacity.

EXECUTIVE COMPENSATION Compensation Discussion and Analysis Overview As a publicly traded partnership, we have a unique employment and compensation structure that is different from that of a typical public corporation. Our executive officers based in Houston, Texas are employed by Quintana Minerals Corporation (“Quintana”), and our executive officers based in Huntington, West Virginia are employed by Western Pocahontas Properties Limited Partnership (“Western Pocahontas”). Quintana and Western Pocahontas are controlled by our Chairman and Chief Executive Officer and are affiliates of NRP. While our executive officers are employed by affiliates of NRP, each of them has been appointed to serve as an executive officer of GP Natural Resource Partners LLC (“GP LLC”), the general partner of NRP (GP) LLC (“NRP GP”), the general partner of NRP. For a more detailed description of our structure, see " Items 1. and 2. Business and Properties — Partnership Structure and Management " in this Annual Report on Form 10 -K. Although our executives’ salaries and bonuses are paid directly by the private companies that employ them, we reimburse those companies based on the time allocated to NRP by each executive officer. Our reimbursement for the compensation of executive officers is governed by our partnership agreement. For purposes of this Compensation Discussion and Analysis, our “named executive officers” are: • Corbin J. Robertson, Jr.—Chairman and Chief Executive Officer • Craig W. Nunez—President and Chief Operating Officer • Christopher J. Zolas—Chief Financial Officer • Philip T. Warman—General Counsel and Secretary • Kevin J. Craig—Executive Vice President Executive Officer Compensation Strategy and Philosophy Under our partnership agreement, each quarter we are required to distribute all of our available cash, as such term is defined in our partnership agreement. The Board of Directors considers numerous factors each quarter in determining cash distributions including profitability, cash flow, debt service obligations, market conditions and outlook, estimated unitholder income tax liability and the level of cash reserves that the board determines are necessary for future operating and capital needs. Our primary objective over the last ten years has been to use all internally generated cash flow to reduce debt while paying distributions to common unitholders sufficient to cover income tax liability on their share of the partnership’s taxable income. Our compensation philosophy is designed to attract, motivate and retain highly talented executives, while keeping them focused on promoting our strategic objectives to manage the business under current market conditions and position the partnership as a key beneficiary of the transitional energy economy of the future. Our objective in determining the compensation of our executive officers is to incentivize them to create long-term value for our unitholders and other stakeholders. We believe our compensation programs encourage sustained long-term profitability by making a portion of each executive officer’s total direct compensation variable and dependent on our achievement of safety, financial and strategic performance goals as well as the total unitholder return of our common units. Thus, a significant portion of our executives’ total compensation is performance-based and not guaranteed, as further described under “—Components of Compensation.” Although we reimburse Quintana and Western Pocahontas, as applicable, for the applicable portion of our executive officers’ compensation, the CNG Committee is responsible for administering our executive officer compensation programs. To help retain and motivate executives, the CNG Committee aims to offer competitive compensation packages through a mix of cash and long-term, equity-based incentives. The CNG Committee does not have any formal policies for allocating total compensation among the various components. Instead, the CNG Committee uses its judgment, in consultation with the independent compensation consultant, to establish an appropriate balance of short-term and long-term compensation for such executive officers for their services to us. The balance may change from year to year based on the amount of time an executive spends in service to us, our corporate strategy, financial performance and non-financial objectives, among other considerations. Summary of Compensation Practices We strive to maintain judicious governance standards and compensation practices by regularly reviewing best practices. The CNG Committee incorporated many best practices when forming our 2025 compensation program, including the following: What We Do ✔ Align our executive compensation with long-term performance ✔ Align executives’ interests with those of unitholders ✔ Engage an independent compensation consultant, Meridian Compensation Consultants ("Meridian"), to assess our practices ✔ Maintain trading policies that restrict all employees and directors from pledging or short selling our securities, entering into any derivative transactions with respect to our securities, or otherwise hedging the risk and rewards of our securities ✔ Review the independence of any compensation consultant that is engaged to assist in our compensation analysis ✔ Provide limited perquisites What We Don ’ t Do ✘ Automatically increase salaries each year or make lock-step changes in compensation based on peer group compensation levels or metrics ✘ Pay guaranteed or multi-year cash bonuses ✘ Provide significant perquisites ✘ Provide tax gross-ups 89 Table of Contents The 2025 compensation for executive officers consisted of four primary components: • base salaries; • short-term cash incentive compensation; • long-term equity incentive compensation; and • perquisites and other benefits. Mr. Robertson does not receive a salary in his capacity as Chief Executive Officer. Mr. Robertson is compensated through short-term cash and long-term equity incentive awards, all of which is allocated to NRP. To the extent other executive officers spend time on non-NRP matters, NRP bears only the proportionate cost of their base salaries, short-term cash incentive compensation and perquisites and other benefits. In February of each year, the CNG Committee approves the short-term cash incentive awards for the year just ended and long-term incentive awards for the executive officers. The CNG Committee considers the performance of the partnership, the performance of the individuals and the outlook for the future in determining the amounts of the awards. Each February, the CNG Committee also makes awards of equity-based awards to be settled in common units under the Natural Resource Partners 2017 Plan to NRP’s officers in order to incentivize management and align the long-term interests of management and NRP unitholders. Role of the CNG Committee The CNG Committee oversees our executive compensation and employee benefit programs, and reviews and approves all compensation decisions relating to our executive officers and directors. The CNG Committee also approves its report for inclusion in this Annual Report and has reviewed and discussed this Compensation Discussion and Analysis with management. Specifically, the CNG Committee reviews and approves the compensation for our executive officers. It reviews and approves the annual and long-term incentive plans in which our executive officers participate, and it also reviews and approves compensation programs for the members of the Board of Directors, as described further below. Role of Independent Compensation Consultant and Market Data The CNG Committee engaged Meridian to review our compensation practices for executive officers and directors relative to our peers. Meridian provides no services to management or the CNG Committee that are unrelated to the duties and responsibilities of the CNG Committee, and the CNG Committee makes all decisions regarding the compensation of our executive officers and directors. Meridian reports directly to the CNG Committee, and all work conducted by Meridian for us is on behalf of the CNG Committee. The CNG Committee has determined that no conflicts of interest exist as a result of the engagement of Meridian. The CNG Committee, with input from Meridian, selected our peer group (the “Peer Group”) after reviewing annual revenue, market capitalization, total enterprise value and total assets of relevant public companies to determine which companies were representative of the marketplace for talent within which we compete. The CNG Committee will review the Peer Group annually to ensure continued appropriateness for comparative purposes. The CNG Committee determined that the companies below reflect an appropriate Peer Group for 2025: Alpha Metallurgical Resources, Inc. Kimbell Royalty Partners, LP SunCoke Energy, Inc. Amplify Energy Corp. NACCO Industries, Inc. Talos Energy Inc. Berry Corporation Powell Industries, Inc. Vitesse Energy, Inc. Black Stone Minerals, L.P. Ramaco Resources, Inc. W&T Offshore, Inc. Centrus Energy Corp. Ring Energy, Inc. Warrior Met Coal, Inc. Great Lakes Dredge & Dock Corporation Sitio Royalties Corp. Meridian provides the CNG Committee with Peer Group data for comparison purposes, such as to compare equity and pay mix practices. Market pay levels are one of multiple factors considered by the CNG Committee in setting applicable compensation amounts and determining the appropriate design of incentive compensation programs. Role of Our Executive Officers in the Compensation Process With respect to 2025 salaries and short-term cash incentive awards and long-term equity incentive awards, Mr. Nunez, our President and Chief Operating Officer, provided Mr. Robertson with recommendations relating to the executive officers other than himself. Mr. Robertson considered those recommendations and provided the CNG Committee with recommendations for all of the executive officers other than himself. Messrs. Robertson and Nunez considered the factors described elsewhere in this Compensation Discussion and Analysis in recommending, in their discretion, the appropriate amounts of compensation for each executive officer (other than for themselves). Messrs. Robertson and Nunez attended the CNG Committee meetings, other than executive sessions called by the CNG Committee, at which the CNG Committee deliberated and approved the salaries, short-term cash incentive awards and long-term equity incentive awards for 2025. Messrs. Robertson and Nunez were excused from the meetings when the CNG Committee discussed their compensation. 90 Table of Contents Components of Compensation Base Salaries With the exception of Mr. Robertson, who does not receive a salary for his services as Chief Executive Officer, our executive officers are paid an annual base salary by Quintana or Western Pocahontas for services rendered to us by the executive officers during the fiscal year. We then reimburse Quintana and Western Pocahontas based on the time allocated to our business by each executive officer. The base salaries of our executive officers are reviewed on an annual basis as well as at the time of a promotion or other material change in responsibilities. The CNG Committee reviews and approves the full salaries paid to each executive officer by Quintana and Western Pocahontas, based on both the actual time allocations to NRP in the prior year and the anticipated time allocations in the coming year. In determining salaries for NRP's executive officers for 2025, the CNG Committee considered several factors including the executive’s position and level of responsibility within our organization, comparative market data and other external market-based factors. The CNG Committee also considered the individual performance, our partnership’s overall performance during the fiscal year and the individual’s contribution to our overall performance of each member of the executive management team during 2024. Salaries for 2025 are shown in the Summary Compensation Table below. Short-Term Cash Incentive Compensation Short-term cash incentive awards are determined based on the Partnership meeting and exceeding certain annual financial, strategic objectives and safety goals. Short-term cash incentive awards are used to motivate and reward our executive officers. Each executive officer received a short-term cash incentive award approved in February 2026 by the CNG Committee. The amounts awarded with respect to 2025 under this program are disclosed in the Summary Compensation Table under the Bonus column. With respect to 2025, the CNG Committee, using recommendations from Meridian, determined that cash bonuses would be paid based on a percentage of base salary, with our Chief Executive Officer (who is not paid a base salary) receiving a bonus target of approximately 2.3 times the salary of our President and Chief Operating Officer. For 2025, the CNG Committee used free cash flow, strategic objectives and safety as performance measures in determining the amount of bonuses paid under the plan, representing 75%, 20% and 5% of the total award, respectively. Based on the level of achievement of the performance measures, the CNG Committee used its discretion to set the amount of bonus payments as a percentage of target. The following table shows the performance measures used in the 2025 short-term cash incentive compensation for our executive officers, together with the percentage of the total annual cash incentive grant that such component comprises. Each of the components for the executive officers is described in greater detail below: Performance Measure 2025 Portion of Total Target Award Free Cash Flow 75% Strategic Objectives 20% Safety 5% We believe that these performance measures align our short-term incentive compensation with both unitholder and employee interests by targeting specific performance goals set forth in the first quarter of each year. By identifying meaningful performance measures, and by assigning greater weight to certain measures, we are able to more closely align compensation to the achievement of those business objectives over which particular employees have the greatest impact. If the target level of performance is achieved with respect to a particular performance measure, the applicable payout percentage for that performance measure will equal 100%. Achievement at the threshold performance level results in a payout percentage for that performance measure that will equal 50%. If the maximum level of performance is achieved with respect to a particular performance measure the payout percentage for that measure will equal 200% of target performance, with the exception of safety which is capped at 100%. We interpolate payouts under the annual cash incentive awards for performance levels that fall between the threshold, target and maximum performance levels. There is no payout for performance that does not meet the threshold level criteria and there is no payout in excess of the maximum performance level. Free Cash Flow “Free Cash Flow” is calculated as cash flow from operating activities plus return on long-term contract receivable less cash flow used in investing activities, excluding proceeds from asset sales. Further, the CNG Committee determined that Free Cash Flow would be adjusted to exclude free cash flow received from Sisecam Wyoming. The CNG Committee utilized the budget approved by the Board during the annual review process and set the “target” level for this performance measure at 100% of budget. The threshold payout value was set at 80% of the Free Cash Flow budget and the maximum payout value was set at 120% of the budget. We consider this performance measure to be difficult to attain and appropriately reflective of our position in the inherently volatile commodities market. The following table shows the threshold, target and maximum levels for the 2025 short-term cash incentive compensation plan: Performance Measure Threshold Target Maximum Free Cash Flow $132,165,600 $165,207,000 $198,248,400 91 Table of Contents Strategic Objectives Strategic Objectives are approved by the Board of Directors each year and reflect the broad strategic objectives of the Partnership, which may change year to year. The measure of performance of these strategic objectives is evaluated annually by the CNG Committee and the threshold, target and maximum payouts are at the discretion of the CNG Committee. Safety Safety is an important emphasis for the Partnership and, the Board of Directors believes, each of the Partnership's stakeholders. Strong safety performance leads to improved employee performance and lower costs associated with regulatory citations, insurance and litigation matters, which in turn lead to improved operating performance. Because of these factors, the CNG Committee uses Reportable Injuries and Lost Time Incidents as a component of the annual incentive compensation plan. Due to the non-operating nature of our business, the “Reportable Injuries and Lost Time Incidents” are set at a target of zero, with threshold or maximum measure. Additionally, the CNG Committee considers the Partnership's completion rate for annual safety trainings with a 100% employee completion rate. 2025 Payout Under the Short-term Cash Incentive Compensation Plan In early 2026, the CNG Committee evaluated the levels of achievement of the various performance measures for 2025 and made the following determinations: Performance Measure Actual Performance Applicable Payout Percentage Relative Weighting Weighted Payout Percentage Free Cash Flow $161,064,000 94% 75% 70% Strategic Objectives Board Satisfaction 100% 20% 20% Safety 100% 100% 5% 5% Based on the actual performance as set forth above, the cumulative amounts listed below were earned under the 2025 short-term cash incentive compensation for the Partnership's 2025 performance.

Our CNG Committee believes that awards under the 2017 Plan promote the alignment of the interests of management with those of our unitholders and promote creation of value for our unitholders. In 2023, the CNG Committee determined it was appropriate to introduce additional performance measures in connection with long-term compensation to better align executive compensation with the Partnership's performance. We refer to these awards issued in 2025 as “2017 Plan Phantom Units.” The 2025 awards were made in the form of phantom units that will settle (following vesting) in NRP common units on a one-for-one basis and will accrue tandem distribution equivalent rights (“DERs”) to be paid in cash upon settlement. 2025 Annual Grants The award granted in February 2025 (“2025 Award”) provided a form of performance-based long-term incentive compensation. This award included a mix of time-based and performance-based phantom units awarded at target; 35% will time-vest ratably over a three-year period and 65% will cliff vest with the actual number of units issued vesting for each phantom unit to be determined by the performance score. The performance score shall be the relative total unit holder return (“TUR”) performance score plus the financial performance score, both weighted at 50%. The 2017 Plan Phantom Units are subject to forfeiture and will vest on an accelerated basis following death or disability of the award recipient, following a change in control of NRP, or termination without cause or for good reason. The grant date fair value of the 2017 Plan Phantom Units awarded in 2025 is disclosed in the Summary Compensation Table under the Stock Awards column. In determining the award amounts the CNG Committee used a percent target of base salary. The following table sets forth the long-term equity award targets and number of units granted to each named executive officer in 2025: 2025 Award Named Executive Officer Target as % of Base Salary Time-Based Performance-Based Corbin J. Robertson, Jr. (1) 1.84x 7,515 13,957 Craig W. Nunez 224% 4,085 7,586 Christopher J. Zolas 153% 1,977 3,672 Philip T. Warman 85% 1,098 2,040 Kevin J. Craig 90% 1,131 2,101 (1) As Mr. Robertson does not receive a salary, his annual cash incentive is calculated as a multiple of the President and Chief Operating Officer’s base salary. Relative Total Unitholder Return For the relative TUR measure, the performance-based units will be eligible to vest based on the Partnership's TUR relative to the Partnership's performance peer group over the three-year performance period. The TUR calculation will be based on a “point-to-point” approach using the 20 calendar-day volume-weighted average of the closing price per share of the Partnership or a member of the peer group, as applicable, at the beginning and end of the performance period. In the event that our TUR is negative, the payout will be capped at target, regardless of peer group performance. In the instance of a merger, acquisition or delisting of a peer company during the performance period, the company would be removed from the peer group. The peer group for the 2025 LTIP awards consists of the companies being utilized for our performance peer group at the time of the grant and are listed below: Alliance Resource Partners, L.P. Peabody Energy Corporation Alpha Metallurgical Resources, Inc. Ramaco Resources, Inc. Corsa Coal Corp. SunCoke Energy, Inc. Core Natural Resources, Inc. Warrior Met Coal, Inc. If the target level of performance is achieved, the payout percentage will equal 100%. Achievement at the threshold performance level will result in a payout at 50% of target performance and achievement at the maximum performance level will result in a payout at 200% of target performance. We interpolate payouts for performance levels that fall between the stated performance levels. There is no payout for performance that does not meet the threshold level and there is no payout in excess of the maximum performance level. The following table shows the performance levels for the 2025 long-term performance-based equity awards: Performance Measure Threshold Target Maximum Relative Total Unitholder Return ​ 18th Percentile 45th Percentile ​ 91st Percentile 93 Table of Contents Financial Performance Score The financial performance score is calculated based on cumulative three-year free cash flow. “Free Cash Flow” is defined as cash from operating activities plus return on long-term contract receivable less cash flow used in investing activities, excluding proceeds from asset sales. Added back to the calculation of Free Cash Flow is additional cash paid for interest on debt used for early settlement of outstanding warrants and preferred units. Payouts will be determined based on the achievement of cumulative free cash flow relative to targets set by the CNG Committee. We consider this performance measure to be difficult to attain and appropriately reflective of our position in the inherently volatile commodities market. Payout of 2023 Performance-Based Awards The vesting of the performance-based awards is calculated annually based on pre-established, weighted goals. Our CNG Committee designs the targets for our future performance goals to be attainable but reasonably difficult to meet. The table below summarizes the target performance goals for 2023 performance-based awards as well as the threshold (50% of target) and the maximum (200% of target) goals compared to actual performance. Performance Measure Threshold (50% Payout) Target (100% Payout) Maximum (200% Payout) Actual Performance Relative Total Unitholder Return 18th Percentile 45th Percentile 91st Percentile 100th Percentile Free Cash Flow $688,000,000 $809,000,000 $930,000,000 $746,000,000 In February 2026, the CNG Committee evaluated and certified our achievement against the above-described performance measures and determined the payout factor was 137% based on actual performance. Our CNG Committee determined our executive officers earned the following payouts with respect to the 2023 performance-based awards at 137% of target. Named Executive Officer Units at Target Units Earned Corbin J. Robertson, Jr. 29,466 40,368 Craig W. Nunez 16,014 21,939 Christopher J. Zolas 7,751 10,619 Philip T. Warman 4,292 5,880 Kevin J. Craig 4,420 6,055 Perquisites and Other Personal Benefits Both Quintana and Western Pocahontas maintain employee benefit plans that provide our executive officers and other employees with the opportunity to enroll in health, dental and life insurance plans. Each of these benefit plans requires the employee to pay a portion of the health and dental premiums, with the company paying the remainder. These benefits are offered on the same basis to all employees of Quintana and Western Pocahontas, and the company costs are reimbursed by us to the extent the employee allocates time to our business. In 2025, Quintana and Western Pocahontas maintained tax-qualified 401(k) plans. During 2025, Quintana and Western Pocahontas matched 100% of the first 6.0% of the employee contributions under their respective 401(k) plans. As with the other contributions, any amounts contributed by Quintana and Western Pocahontas are reimbursed by us based on the time allocated by the employee to our business. None of NRP, Quintana or Western Pocahontas maintains a pension plan or a defined benefit retirement plan. Other Compensation Policies and Practices Unit Ownership Requirements NRP maintains Unit Ownership and Retention Guidelines (the “ownership guidelines”) that are administered by the CNG Committee and require NRP’s officers who are required to file ownership reports under Section 16 of the Securities Exchange Act of 1934 (the “Exchange Act”) and certain other officers as designated from time-to-time by the Board of Directors or the CNG Committee to retain all common units awarded under any NRP incentive plan (net of any units withheld or sold to cover tax liabilities) until certain ownership guidelines are met. The following table sets forth the ownership guidelines. There is no minimum time period required to achieve the unit ownership guidelines. Position Requirement Chief Executive Officer (1) N/A President and Chief Operating Officer 3 x Salary Chief Financial Officer 3 x Salary General Counsel 1.5 x Salary Executive Vice President 2 x Salary (1) Ownership guidelines due not currently apply to our Chief Executive Officer due to his substantial ownership in NRP. The ownership guidelines also require directors who are not officers to retain common units with a value equal to three times the amount of the annual cash retainer paid to directors. Directors are required to achieve the unit ownership guideline within five years. Until the unit ownership guideline is achieved, each director is encouraged to retain all common units awarded under any NRP incentive plan (net of any units sold to cover tax liabilities). Units that count towards the satisfaction of the officer and director guidelines include common units held directly by the executive officer or director, common units owned indirectly by the executive officer or director (e.g., by a spouse or other immediate family member residing in the same household or a trust for the benefit of the executive officer or director or his or her family), units granted under NRP’s long-term incentive plans (including phantom units representing the right to receive units) and units purchased in the open market (whether purchased before or after the effective date of the ownership guidelines). As of December 31, 2025, all executive officers and directors were in compliance with ownership guidelines. 94 Table of Contents Incentive Compensation Recoupment Policy NRP maintains the Natural Resource Partners L.P. Incentive-Based Compensation Recoupment Policy, which is administered by the CNG Committee. The policy authorizes the Board of Directors or any committee thereof to recoup incentive compensation in the event of a restatement of financial statements due to material non-compliance with securities laws, fraud or misconduct. See policy at Exhibit 97.1 in this Annual Report on Form 10-K. Securities Trading Policy Our insider trading policy restricts employees and directors, as well as their designees, from purchasing or selling puts or calls to sell or buy our common units, engaging in short sales with respect to our common units, buying our securities on margin or pledging our securities to secure debt or engaging in any transactions that would be deemed to be a hedging transaction involving our securities. See policy as Exhibit 19.1 in this Annual Report on Form 10-K. Policies and Practices Related to Stock Options We do not currently grant, nor have we historically granted, stock options or similar awards as part of our equity compensation programs. If stock options or similar awards were to be granted in the future, NRP would not grant such options or similar awards in anticipation of the release of material nonpublic information that is likely to result in changes to the price of our common units. During fiscal year 2025, we did not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. Risk Assessment of Compensation Plans We believe that our compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs and the compensation arrangements are designed to encourage our employees, including our executive officers, to focus on both short-term and long-term strategic goals, thereby creating an ownership culture and helping to align the interests of our employees and our unitholders. Accordingly, our compensation program is balanced between short-term and long-term incentives, as well as cash and equity-based forms of settlement. Overall, we believe that the balance within our compensation program results in an appropriate compensation structure and that the program does not pose risks that could have a material adverse effect on our business or financial performance. Report of the Compensation, Nominating and Governance Committee The CNG Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management. Based on the reviews and discussions referred to in the foregoing sentence, the CNG Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K for the year ended December 31, 2025.

(2) Amounts represent the grant date fair value of the 2017 Plan Phantom Units determined in accordance with Accounting Standards Codification Topic 718 determined without regard to forfeitures. The grant date fair value of the performance-based awards is based on the probable outcome of the performance conditions as of the date of grant, which was target. If the maximum amount, rather than the probable amount, were reported in the table with respect to the performance-based awards, the values associated with the performance-based awards would be as follows: Mr. Robertson, $2,896,078; Mr. Nunez, $1,574,095; Mr. Zolas, $761,940; Mr. Warman, $423,300; and Mr. Craig, $435,958. For information regarding the assumptions used in calculating these amounts, see " Item 8. Financial Statements and Supplementary Data—Note 16. Unit-Based Compensation " elsewhere in this Annual Report on Form 10-K for more information. (3) Includes portions of 401(k) matching allocated to Natural Resource Partners by Quintana and Western Pocahontas. (4) Mr. Craig allocated approximately 97% of his time to NRP during the year ended December 31, 2025 and amounts included under the “Salary,” “Bonus” and “All Other Compensation” columns reflect this allocation. Amounts included under “Stock Awards” are paid 100% by NRP. Grants of Plan-Based Awards in 2025 The following table shows the 2017 Plan Phantom Units granted to named executive officers during 2025. Based on the grant, the awards in the table below will either vest ratably in 2026, 2027 and 2028 or cliff vest in 2028. Upon settlement, an equivalent number of common units will be issued to each named executive officer, subject to withholding. The 2017 Plan Phantom Units also accrue DERs from the grant date, which will be paid out in cash upon settlement following and subject to vesting. 2017 Plan Phantom Units Estimated Future Payouts Under Equity Incentive Plan Awards (1) All other Unit Awards (2) Named Executive Officer Grant Date Threshold (#) Target (#) Maximum (#) Units (#) Grant Date Fair Value ($) Corbin J.

(3) Mr. Smith elected to defer settlement of his common units awarded under the 2017 Plan in 2018, 2019, 2020, 2021 and 2022 until 90 days following his retirement or earlier departure from the Board of Directors.

(4) Mr. Murphy joined the CNG Committee effective May 2025 and received prorated committee fees for the remainder of the year. Compensation Committee Interlocks and Insider Participation During the year ended December 31, 2025, Messrs. Vecellio, Murphy, Navarre and Smith served on the CNG Committee. None of Messrs. Vecellio, Murphy, Navarre and Smith has ever been an officer or employee of NRP or GP LLC. None of our executive officers serve as a member of the board of directors or compensation committee of any entity that has any executive officer serving as a member of our Board or CNG Committee. Pay Ratio Disclosure The Securities and Exchange Commission has adopted a rule requiring annual disclosure of the ratio of the median employee’s total annual compensation to the total annual compensation of the principle executive officer. The personnel providing services to us, including our executive officers, are employed by Quintana or Western Pocahontas. As of December 31, 2025, 51 such persons were providing services to us. We identified a new median service provider for 2025 by examining the 2025 total taxable compensation, as reflected in our payroll records as reported to the Internal Revenue Service on Form W-2, for all individuals who provided services to us as of December 31, 2025. We did not make any assumptions, adjustments or estimates with respect to total cash compensation or equity compensation and we did not annualize the compensation for any service providers that were not employed for all of 2025. After identifying the median service provider based on total compensation, we calculated annual 2025 compensation for the median service provider using the same methodology used to calculate the Chief Executive Officer’s total compensation as reflected in the Summary Compensation Table above. The median service provider’s annual 2025 compensation was as follows: Name Year Salary ($) Bonus ($) Non-Equity Incentive Plan Compensation ($) Stock Awards ($) All Other Compensation ($) Total ($) Median Service Provider 2025 118,247 35,000 12,821 — 9,964 176,032 Our 2025 ratio of Chief Executive Officer total compensation of $3,505,945 to our median service provider's total compensation of $176,032 is reasonably estimated to be 20:1. 98 Table of Contents ITEM 12.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE Relationships with Entities Associated with Corbin J. Robertson, Jr. Western Pocahontas Properties Limited Partnership, New Gauley Coal Corporation, and Great Northern Properties Limited Partnership are three privately held companies that are primarily engaged in owning and managing mineral properties. We refer to these companies collectively as the "WPP Group". Corbin J. Robertson, Jr. controls the general partner of Western Pocahontas Properties, 85% of the general partner of Great Northern Properties Limited Partnership and is the Chairman and Chief Executive Officer of New Gauley Coal Corporation. Omnibus Agreement As part of the omnibus agreement entered into concurrently with the closing of our initial public offering (the "Omnibus Agreement"), the WPP Group and any entity controlled by Corbin J. Robertson, Jr., which we refer to in this section as the “GP affiliates,” each agreed that neither they nor their affiliates will, directly or indirectly, engage or invest in entities that engage in the following activities (each, a "restricted business") in the specific circumstances described below: • the entering into or holding of leases with a party other than an affiliate of the GP affiliate for any GP affiliate-owned fee coal within the United States; and • the entering into or holding of subleases with a party other than an affiliate of the GP affiliate for coal within the United States controlled by a paid-up lease owned by any GP affiliate or its affiliate. "Affiliate" means, with respect to any GP affiliate or, any other entity in which such GP affiliate owns, through one or more intermediaries, 50% or more of the then outstanding voting securities or other ownership interests of such entity. Except as described below, the WPP Group and its controlled affiliates will not be prohibited from engaging in activities in which they compete directly with us. A GP affiliate may, directly or indirectly, engage in a restricted business if: • the GP affiliate was engaged in the restricted business at the closing of the offering; provided that if the fair market value of the asset or group of related assets of the restricted business subsequently exceeds $10 million, the GP affiliate must offer the restricted business to us under the offer procedures described below. • the asset or group of related assets of the restricted business have a fair market value of $10 million or less; provided that if the fair market value of the assets of the restricted business subsequently exceeds $10 million, the GP affiliate must offer the restricted business to us under the offer procedures described below. • the asset or group of related assets of the restricted business have a fair market value of more than $10 million and the general partner (with the approval of the conflicts committee) has elected not to cause us to purchase these assets under the procedures described below. • its ownership in the restricted business consists solely of a non-controlling equity interest. For purposes of this paragraph, "fair market value" means the fair market value as determined in good faith by the relevant GP affiliate. The total fair market value in the good faith opinion of the WPP Group of all restricted businesses engaged in by the WPP Group, other than those engaged in by the WPP Group at closing of our initial public offering (and except as described below under "—Pocahontas Royalties LLC"), may not exceed $75 million. For purposes of this restriction, the fair market value of any entity engaging in a restricted business purchased by the WPP Group will be determined based on the fair market value of the entity as a whole, without regard for any lesser ownership interest to be acquired. If the WPP Group desires to acquire a restricted business or an entity that engages in a restricted business with a fair market value in excess of $10 million and the restricted business constitutes greater than 50% of the value of the business to be acquired, then the WPP Group must first offer us the opportunity to purchase the restricted business. If the WPP Group desires to acquire a restricted business or an entity that engages in a restricted business with a value in excess of $10 million and the restricted business constitutes 50% or less of the value of the business to be acquired, then the GP affiliate may purchase the restricted business first and then offer us the opportunity to purchase the restricted business within six months of acquisition. For purposes of this paragraph, "restricted business" excludes a general partner interest or managing member interest, which is addressed in a separate restriction summarized below. For purposes of this paragraph only, "fair market value" means the fair market value as determined in good faith by the relevant GP affiliate. If we want to purchase the restricted business and the GP affiliate and the general partner, with the approval of the conflicts committee, agree on the fair market value and other terms of the offer within 60 days after the general partner receives the offer from the GP affiliate, we will purchase the restricted business as soon as commercially practicable. If the GP affiliate and the general partner, with the approval of the conflicts committee, are unable to agree in good faith on the fair market value and other terms of the offer within 60 days after the general partner receives the offer, then the GP affiliate may sell the restricted business to a third party within two years for no less than the purchase price and on terms no less favorable to the GP affiliate than last offered by us. During this two-year period, the GP affiliate may operate the restricted business in competition with us, subject to the restriction on total fair market value of restricted businesses owned in the case of the WPP Group. 100 Table of Contents If, at the end of the two-year period, the restricted business has not been sold to a third party and the restricted business retains a value, in the good faith opinion of the relevant GP affiliate, in excess of $10 million, then the GP affiliate must reoffer the restricted business to the general partner. If the GP affiliate and the general partner, with the approval of the conflicts committee, agree on the fair market value and other terms of the offer within 60 days after the general partner receives the second offer from the GP affiliate, we will purchase the restricted business as soon as commercially practicable. If the GP Affiliate and the general partner, with the concurrence of the conflicts committee, again fail to agree after negotiation in good faith on the fair market value of the restricted business, then the GP affiliate will be under no further obligation to us with respect to the restricted business, subject to the restriction on total fair market value of restricted businesses owned. In addition, if during the two-year period described above, a change occurs in the restricted business that, in the good faith opinion of the GP affiliate, affects the fair market value of the restricted business by more than 10 percent and the fair market value of the restricted business remains, in the good faith opinion of the relevant GP affiliate, in excess of $10 million, the GP affiliate will be obligated to reoffer the restricted business to the general partner at the new fair market value, and the offer procedures described above will recommence. If the restricted business to be acquired is in the form of a general partner interest in a publicly held partnership or a managing member interest in a publicly held limited liability company, the WPP Group may not acquire such restricted business even if we decline to purchase the restricted business. If the restricted business to be acquired is in the form of a general partner interest in a non-publicly held partnership or a managing member of a non-publicly held limited liability company, the WPP Group may acquire such restricted business subject to the restriction on total fair market value of restricted businesses owned and the offer procedures described above. The Omnibus Agreement may be amended at any time by the general partner, with the concurrence of the conflicts committee. The respective obligations of the WPP Group under the Omnibus Agreement terminate when the WPP Group and its affiliates cease to participate in the control of the general partner. For more information, see the Omnibus Agreement attached as Exhibit 10.3 to this Annual Report on Form 10-K. Pocahontas Royalties LLC On February 28, 2020, Pocahontas Royalties LLC (“Pocahontas Royalties”) completed the acquisition of a private company that owns approximately one million acres of mineral rights and leases coal to coal mine operators in Central Appalachia. Pocahontas Royalties is controlled by Corbin J. Robertson, Jr. and members of his family. Reed Morian, one of the former directors of GP Natural Resource Partners LLC, also serves on the Board of Managers of Pocahontas Royalties. In connection with the closing of the acquisition, we and Pocahontas Royalties entered into a limited waiver of the Omnibus Agreement pursuant to which we waived the provision of the Omnibus Agreement that restricts Mr. Robertson, Jr. and his affiliates (other than NRP) from owning, operating or investing in fee coal in the United States with an aggregate fair market value in excess of $75 million. Mr. Robertson had previously offered NRP the opportunity to participate in the acquisition and we determined, after due consideration, not to participate. In addition, on February 28, 2020, we and Pocahontas Royalties entered into a right of first offer agreement pursuant to which Pocahontas Royalties granted us the exclusive right of first offer to purchase any assets (or entities holding such assets) proposed to be sold at any time by Pocahontas Royalties or any of its subsidiaries with a fair market value exceeding $2 million (individually or in the aggregate), excluding surface acreage, assets or rights (other than surface rights that are appurtenant to or necessary for the development of mineral rights). Provided that Pocahontas Royalties has provided us the opportunity to make a first offer within the time periods specified in the agreement, Pocahontas Royalties will be under no obligation to accept any offer timely made by us and may determine, in its sole discretion, to consummate a transaction with a third party free and clear of any obligations to us. Office Building in Huntington, West Virginia We lease an office building in Huntington, West Virginia from Western Pocahontas Properties Limited Partnership. The initial 10-year term of the lease expired at the end of 2018. On January 1, 2019, we entered into a new lease on the building for a five-year base term, with five additional five-year renewal options. Effective January 1, 2024 we entered into the first five-year renewal term. We paid approximatel y $0.8 million to Western Pocahontas under the lease during the year ended December 31, 2025. 101 Table of Contents Conflicts of Interest Conflicts of interest exist and may arise in the future as a result of the relationships between our general partner and its affiliates (including the WPP Group and Pocahontas Royalties) on the one hand, and our partnership and our limited partners, on the other hand. The directors and officers of GP Natural Resource Partners LLC have duties to manage GP Natural Resource Partners LLC and our general partner in a manner beneficial to its owners. At the same time, our general partner has a duty to manage our Partnership in a manner beneficial to us and our unitholders. The Delaware Revised Uniform Limited Partnership Act, which we refer to as the "Delaware Act", provides that Delaware limited partnerships may, in their partnership agreements, expand, restrict or eliminate the fiduciary duties otherwise owed by a general partner to limited partners and the partnership. Pursuant to these provisions, our partnership agreement contains various provisions modifying the fiduciary duties that would otherwise be owed by our general partner with contractual standards governing the duties of the general partner and the methods of resolving conflicts of interest. Our partnership agreement also specifically defines the remedies available to limited partners for actions taken that, without these defined liability standards, might constitute breaches of fiduciary duty under applicable Delaware law. Whenever a conflict arises between our general partner or its affiliates, on the one hand, and our partnership or any other partner, on the other, our general partner will resolve that conflict. Our general partner may, but is not required to, seek the approval of the conflicts committee of the Board of Directors of such resolution. The partnership agreement contains provisions that allow our general partner to take into account the interests of other parties in addition to our interests when resolving conflicts of interest. Our general partner will not be in breach of its obligations under the partnership agreement or its duties to us or our unitholders if the resolution of the conflict is considered to be fair and reasonable to us. Any resolution is considered to be fair and reasonable to us if that resolution is: • approved by the conflicts committee, although our general partner is not obligated to seek such approval and our general partner may adopt a resolution or course of action that has not received approval; • on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or • fair to us, taking into account the totality of the relationships between the parties involved, including other transactions that may be particularly favorable or advantageous to us. In resolving a conflict, our general partner, including its conflicts committee, may, unless the resolution is specifically provided for in the partnership agreement, consider: • the relative interests of any party to such conflict and the benefits and burdens relating to such interest; • any customary or accepted industry practices or historical dealings with a particular person or entity; • generally accepted accounting practices or principles; and • such additional factors it determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances. Conflicts of interest could arise in the situations described below, among others. Actions taken by our general partner may affect the amount of cash available for distribution to unitholders. The amount of cash that is available for distribution to unitholders is affected by decisions of our general partner regarding such matters as: • amount and timing of asset purchases and sales; • cash expenditures; • borrowings; • the issuance of additional common units; and • the creation, reduction or increase of mineral rights in any quarter. In addition, borrowings by us and our affiliates do not constitute a breach of any duty owed by our general partner to the unitholders, including borrowings that have the purpose or effect of enabling our general partner to receive distributions. For example, in the event we have not generated sufficient cash from our operations to pay the quarterly distribution on our common units, our partnership agreement permits us to borrow funds which may enable us to make this distribution on all outstanding common units. The partnership agreement provides that we and our subsidiaries may borrow funds from our general partner and its affiliates. Our general partner and its affiliates may not borrow funds from us or our subsidiaries. We do not have any officers or employees. We rely on officers and employees of GP Natural Resource Partners LLC and its affiliates. We do not have any officers or employees and rely on officers and employees of GP Natural Resource Partners LLC and its affiliates. Affiliates of GP Natural Resource Partners LLC conduct businesses and activities of their own in which we have no economic interest. If these separate activities are significantly greater than our activities, there could be material competition for the time and effort of the officers and employees who provide services to our general partner. The officers of GP Natural Resource Partners LLC are not required to work full time on our affairs. Certain of these officers devote significant time to the affairs of the WPP Group or its affiliates and are compensated by these affiliates for the services rendered to them. 102 Table of Contents We reimburse our general partner and its affiliates for expenses. We reimburse our general partner and its affiliates for costs incurred in managing and operating us, including costs incurred in rendering corporate staff and support services to us. The partnership agreement provides that our general partner determines the expenses that are allocable to us in any reasonable manner determined by our general partner in its sole discretion. Our general partner intends to limit its liability regarding our obligations. Our general partner intends to limit its liability under contractual arrangements so that the other party has recourse only to our assets, and not against our general partner or its assets. The partnership agreement provides that any action taken by our general partner to limit its liability or our liability is not a breach of our general partner’s fiduciary duties, even if we could have obtained more favorable terms without the limitation on liability. Common unitholders have no right to enforce obligations of our general partner and its affiliates under agreements with us. Any agreements between us on the one hand, and our general partner and its affiliates, on the other, do not grant to the unitholders, separate and apart from us, the right to enforce the obligations of our general partner and its affiliates in our favor. Contracts between us, on the one hand, and our general partner and its affiliates, on the other, are not the result of arm ’ s-length negotiations. The partnership agreement allows our general partner to pay itself or its affiliates for any services rendered to us, provided these services are rendered on terms that are fair and reasonable. Our general partner may also enter into additional contractual arrangements with any of its affiliates on our behalf. Neither the partnership agreement nor any of the other agreements, contracts and arrangements between us, on the one hand, and our general partner and its affiliates, on the other, are the result of arm’s-length negotiations. All of these transactions entered into after our initial public offerings are on terms that are fair and reasonable to us. Our general partner and its affiliates have no obligation to permit us to use any facilities or assets of our general partner and its affiliates, except as may be provided in contracts entered into specifically dealing with that use. There is no obligation of our general partner or its affiliates to enter into any contracts of this kind. We may not choose to retain separate counsel for ourselves or for the holders of common units. The attorneys, independent auditors and others who have performed services for us in the past were retained by our general partner, its affiliates and us and have continued to be retained by our general partner, its affiliates and us. Attorneys, independent auditors and others who perform services for us are selected by our general partner or the conflicts committee and may also perform services for our general partner and its affiliates. We may retain separate counsel for ourselves or the holders of common units in the event of a conflict of interest arising between our general partner and its affiliates, on the one hand, and us or the holders of common units, on the other, depending on the nature of the conflict. We do not intend to do so in most cases. Delaware case law has not definitively established the limits on the ability of a partnership agreement to restrict such fiduciary duties. Our general partner ’ s affiliates may compete with us. The partnership agreement provides that our general partner is restricted from engaging in any business activities other than those incidental to its ownership of interests in us. Except as provided in our partnership agreement and the Omnibus Agreement, affiliates of our general partner will not be prohibited from engaging in activities in which they compete directly with us. The Conflicts Committee Charter is available upon request. Director Independence For a discussion of the independence of the members of the Board of Directors of our managing general partner under applicable standards, see " Item 10. Directors and Executive Officers of the Managing General Partner and Corporate Governance—Corporate Governance—Independence of Directors ," which is incorporated by reference into this Item 13. Review, Approval or Ratification of Transactions with Related Persons If a conflict or potential conflict of interest arises between our general partner and its affiliates (including the WPP Group and Pocahontas Royalties) on the one hand, and our partnership and our limited partners, on the other hand, the resolution of any such conflict or potential conflict is addressed as described under "—Conflicts of Interest." Pursuant to our Code of Business Conduct and Ethics, conflicts of interest are prohibited as a matter of policy, except under guidelines approved by the Board of Directors and as provided in the Omnibus Agreement and our partnership agreement. For the year ended December 31, 2025 there were no transactions where such guidelines were not followed. 103 Table of Contents ITEM 14.

(2) Tax fees include fees principally incurred for assistance with tax planning, compliance, tax return preparation and filing of Schedules K-1. Audit and Non-Audit Services Pre-Approval Policy I. Statement of Principles Under the Sarbanes-Oxley Act of 2002 (the "Act"), the Audit Committee of the Board of Directors is responsible for the appointment, compensation and oversight of the work of the independent auditor. As part of this responsibility, the Audit Committee is required to pre-approve the audit and non-audit services performed by the independent auditor in order to assure that they do not impair the auditor’s independence from the Partnership. To implement these provisions of the Act, the SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee’s administration of the engagement of the independent auditor. Accordingly, the Audit Committee has adopted, and the Board of Directors has ratified, this Audit and Non-Audit Services Pre-Approval Policy (the "Policy"), which sets forth the procedures and the conditions pursuant to which services proposed to be performed by the independent auditor may be pre-approved. The SEC’s rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. Proposed services may either be pre-approved without consideration of specific case-by-case services by the Audit Committee ("general pre-approval") or require the specific pre-approval of the Audit Committee ("specific pre-approval"). The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the independent auditor. As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee if it is to be provided by the independent auditor. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee. For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service for reasons such as its familiarity with our business, employees, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Partnership’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor will necessarily be determinative. The Audit Committee is also mindful of the relationship between fees for audit and non-audit services in deciding whether to pre-approve any such services and may determine, for each fiscal year, the appropriate ratio between the total amount of fees for audit, audit-related and tax services. The appendices to the Policy describe the audit, audit-related and tax services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers a different period and states otherwise. For the audit, pre-approval is for the fiscal year as the time between approval and the actual issuance of the audit may be more than 12 months. The Audit Committee will annually review and pre-approve the services that may be provided by the independent auditor without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add or subtract to the list of general pre-approved services from time to time, based on subsequent determinations. The purpose of this Policy is to set forth the procedures by which the Audit Committee intends to fulfill its responsibilities. It does not delegate the Audit Committee’s responsibilities to pre-approve services performed by the independent auditor to management. Ernst & Young LLP, our independent auditor reviews this Policy annually and it does not adversely affect its independence. II. Delegation As provided in the Act and the SEC’s rules, the Audit Committee has delegated either type of pre-approval authority to Stephen P. Smith, the Chairman of the Audit Committee. Mr. Smith must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting. 104 Table of Contents III. Audit Services The annual Audit services engagement terms and fees will be subject to the specific pre-approval of the Audit Committee. Audit services include the annual financial statement audit (including required quarterly reviews), subsidiary audits and other procedures required to be performed by the independent auditor to be able to form an opinion on the Partnership’s consolidated financial statements. These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit or quarterly review. Audit services also include the attestation engagement for the independent auditor’s report on internal controls for financial reporting. The Audit Committee monitors the audit services engagement as necessary, but not less than on a quarterly basis, and approves, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, partnership structure or other items. In addition to the annual audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other audit services, which are those services that only the independent auditor reasonably can provide. Other audit services may include statutory audits or financial audits for our subsidiaries or our affiliates and services associated with SEC registration statements, periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings. IV. Audit-related Services Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Partnership’s financial statements or that are traditionally performed by the independent auditor. Because the Audit Committee believes that the provision of audit-related services does not impair the independence of the auditor and is consistent with the SEC’s rules on auditor independence, the Audit Committee may grant general pre-approval to audit-related services. Audit-related services include, among others, due diligence services pertaining to potential business acquisitions/dispositions; accounting consultations related to accounting, financial reporting or disclosure matters not classified as "Audit Services"; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; financial audits of employee benefit plans; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements. V. Tax Services The Audit Committee believes that the independent auditor can provide tax services to the Partnership such as tax compliance, tax planning and tax advice without impairing the auditor’s independence, and the SEC has stated that the independent auditor may provide such services. Hence, the Audit Committee believes it may grant general pre-approval to those tax services that have historically been provided by the auditor, that the Audit Committee has reviewed and believes would not impair the independence of the auditor and that are consistent with the SEC’s rules on auditor independence. The Audit Committee will not permit the retention of the independent auditor in connection with a transaction initially recommended by the independent auditor, the sole business purpose of which may be tax avoidance and the tax treatment of which may not be supported in the Internal Revenue Code and related regulations. The Audit Committee will consult with the Chief Financial Officer or outside counsel to determine that the tax planning and reporting positions are consistent with this Policy. VI. Pre-Approval Fee Levels or Budgeted Amounts Pre-approval fee levels or budgeted amounts for all services to be provided by the independent auditor will be established annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee. The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services. For each fiscal year, the Audit Committee may determine the appropriate ratio between the total amount of fees for audit, audit-related and tax services. VII. Procedures All requests or applications for services to be provided by the independent auditor that do not require specific approval by the Audit Committee will be submitted to the Chief Financial Officer and must include a detailed description of the services to be rendered. The Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services rendered by the independent auditor. Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the independent auditor and the Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC’s rules on auditor independence. 105 Table of Contents PART IV ITEM 15.
