Natural Resource Partners L.P. Reports Second Quarter 2025 Results and Declares Second Quarter 2025 Distribution of $0.75 per Common Unit

Natural Resource Partners L.P. (NYSE:NRP) today reported second quarter 2025 results as follows:

Highlights:

• Generated $46.3 million of free cash flow in the second quarter of 2025
• Paid first quarter 2025 common unit distribution of $0.75 per unit
• Declares second quarter 2025 common unit distribution of $0.75 per unit

"NRP generated $46 million of free cash flow in the second quarter of 2025 and $203 million of free cash flow over the last twelve months," said Craig Nunez, NRP's president and chief operating officer. "Although we experienced another quarter of weak prices for metallurgical coal, thermal coal, and soda ash, the partnership continues to generate significant free cash flow and make progress towards our goal to pay off all remaining debt, of which only $102 million remains."

NRP announced today that the board of directors of its general partner declared a second quarter 2025 cash distribution of $0.75 per common unit to be paid on August 26, 2025, to unitholders of record on August 19, 2025. Future distributions on NRP's common units will be determined on a quarterly basis by the board of directors. 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 is necessary for future operating and capital needs.

Segment Performance

Mineral Rights

Mineral Rights net income for the second quarter of 2025 decreased $13.0 million as compared to the prior year period. Mineral Rights operating cash flow and free cash flow decreased $10.7 million and $10.6 million, respectively, as compared to the prior year period. These decreases were primarily due to lower metallurgical coal sales prices and volumes as compared to the prior year period. Approximately 70% of coal royalty revenues and approximately 55% of coal royalty sales volumes were derived from metallurgical coal in the second quarter of 2025.

Metallurgical and thermal coal prices remained weak throughout the quarter and NRP expects muted pricing for both commodities for the remainder of 2025. Stagnant global steel demand and regulatory uncertainty continue to impact metallurgical coal markets and more than substantial thermal coal inventory levels at domestic power plants continue to stifle domestic thermal markets.

No meaningful developments have occurred over the past quarter regarding NRP's carbon neutral revenue activities across its mineral and surface assets. While the timing and likelihood of additional cash flows from carbon neutral activities such as the sequestration of carbon dioxide underground and in standing forests, lithium production, and electric generation via renewable energy sources is uncertain, NRP believes its vast ownership footprint throughout the United States provides additional opportunities to create value in this regard with minimal capital investment by NRP.

Soda Ash

Soda Ash net income in the second quarter of 2025 decreased $1.1 million as compared to the prior year period primarily due to lower sales prices in 2025. Operating cash flow and free cash flow in the second quarter of 2025 each decreased $2.7 million as compared to the prior year period due to a lower cash distribution received from Sisecam Wyoming in the second quarter of 2025.

The soda ash market remains significantly oversupplied due to the substantial increase in global capacity in recent years, as well as weakening demand for flat glass due to sluggish global construction activity and decreased demand for new automobiles and solar panels. NRP believes international soda ash prices are at or below the cost of production for many operators and expects this weak pricing environment to continue for the foreseeable future until high-cost supply is forced out of the market or global soda ash demand growth catches up with supply. NRP expects distributions from Sisecam Wyoming to remain below historical norms for the foreseeable future.

Corporate and Financing

Corporate and Financing net income, operating cash flow, and free cash flow each increased $2.3 million in the second quarter of 2025 as compared to the prior year period. These increases were primarily due to lower interest expense and cash paid for interest in the second quarter of 2025 as compared to the prior year period as a result of increased borrowings on the credit facility in 2024 used for warrant settlements and preferred unit redemptions.

In May 2025, NRP paid a first quarter 2025 cash distribution of $0.75 per common unit. Today, NRP declared a second quarter 2025 cash distribution of $0.75 per common unit.

NRP's available liquidity was $157.5 million at June 30, 2025, consisting of $30.3 million of cash and cash equivalents and $127.1 million of borrowing capacity available under its revolving credit facility.

NRP's consolidated leverage ratio was 0.5 x at June 30, 2025.

Non-GAAP Financial Measures

"Adjusted EBITDA" is a non-GAAP financial measure that we define as net income (loss) less equity earnings from unconsolidated investment; plus total distributions from unconsolidated investment, interest expense, net, debt modification expense, loss on extinguishment of debt, depreciation, depletion and amortization and asset impairments. Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income or loss, net income or loss attributable to partners, operating income or loss, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP as measures of operating performance, liquidity or ability to service debt obligations. There are significant limitations to using Adjusted EBITDA as a measure of performance, including the inability to analyze the effect of certain recurring items that materially affect our net income, the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted EBITDA reported by different companies. In addition, Adjusted EBITDA presented below is not calculated or presented on the same basis as Consolidated EBITDA as defined in our partnership agreement or Consolidated EBITDDA as defined in Opco's debt agreements. Adjusted EBITDA is a supplemental performance measure used by our management and by external users of our financial statements, such as investors, commercial banks, research analysts and others to assess the financial performance of our assets without regard to financing methods, capital structure or historical cost basis.

"Distributable cash flow" or "DCF" is a non-GAAP financial measure that we define as net cash provided by (used in) operating activities plus distributions from unconsolidated investment in excess of cumulative earnings, proceeds from asset sales and disposals, including sales of discontinued operations, and return of long-term contract receivable; less maintenance capital expenditures. DCF is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing or financing activities. DCF may not be calculated the same for us as for other companies. In addition, distributable cash flow is not calculated or presented on the same basis as distributable cash flow as defined in our partnership agreement, which is used as a metric to determine whether we are able to increase quarterly distributions to our common unitholders. Distributable cash flow is a supplemental liquidity measure used by our management and by external users of our financial statements, such as investors, commercial banks, research analysts and others to assess our ability to make cash distributions and repay debt.

"Free cash flow" or "FCF" is a non-GAAP financial measure that we define as net cash provided by (used in) operating activities plus distributions from unconsolidated investment in excess of cumulative earnings and return of long-term contract receivable; less maintenance and expansion capital expenditures and cash flow used in acquisition costs classified as investing or financing activities. FCF is calculated before mandatory debt repayments. Free cash flow is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing or financing activities. Free cash flow may not be calculated the same for us as for other companies. Free cash flow is a supplemental liquidity measure used by our management and by external users of our financial statements, such as investors, commercial banks, research analysts and others to assess our ability to make cash distributions and repay debt.

"Leverage ratio" represents the outstanding principal of NRP's debt at the end of the period divided by the last twelve months' Adjusted EBITDA as defined above. NRP believes that leverage ratio is a useful measure to management and investors to evaluate and monitor the indebtedness of NRP relative to its ability to generate income to service such debt and in understanding trends in NRP's overall financial condition. Leverage ratio may not be calculated the same for NRP as for other companies and is not a substitute for, and should not be used in conjunction with, GAAP financial ratios.
