• Paid fourth quarter 2022 common unit distribution of $0.75 and special common unit distribution of $2.43

"NRP's strong performance continued in the first quarter of 2023 driven by robust prices for metallurgical coal and soda ash," said Craig Nunez, NRP's president and chief operating officer. "In addition to generating $73 million of free cash flow, we redeemed $47.5 million of preferred units at par with cash and permanently retired $16.7 million of Opco Senior Notes. We will continue to aggressively pay off debt and preferred equity with internally generated cash while maintaining distributions to our common unitholders.”

NRP announced today that the board of directors of its general partner declared a first quarter 2023 cash distribution of $0.75 per common unit to be paid on May 23, 2023, to unitholders of record on May 16, 2023. In addition, the board declared a $6.1 million cash distribution on NRP's outstanding preferred units. Future distributions on NRP's common and preferred 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.

NRP's liquidity was $56.5 million at March 31, 2023, consisting of $17.7 million of cash and $38.8 million of borrowing capacity available under its revolving credit facility.

Segment Performance

Mineral Rights

Mineral Rights net income for the first quarter of 2023 increased $5.9 million as compared to the prior year period primarily due to increased metallurgical coal sales volumes and revenue from carbon neutral initiatives. Operating cash flow and free cash flow for the first quarter of 2023 increased $25.7 million and $26.3 million, respectively, as compared to the prior year period primarily due to the timing of minimum and royalty payments and prior year recoupments. Approximately 75% of coal royalty revenues and approximately 55% of coal royalty sales volumes were derived from metallurgical coal in the first quarter of 2023.

Metallurgical and thermal coal prices remain strong relative to historical norms, although pricing has declined from the record highs seen in 2022. Continued support for pricing is expected as operators are limited in their ability to increase production due to ongoing labor shortages, transportation and logistics challenges, difficulty of new mine permitting, and limited access to capital.

NRP continues to explore and identify carbon neutral revenue opportunities across its large portfolio of land, mineral, and timber assets, including the sequestration of carbon dioxide underground and in standing forests, and the generation of electricity using geothermal, solar, and wind energy. In the first quarter of 2023, NRP executed a new solar lease.

Soda Ash

Soda Ash net income in the first quarter of 2023 increased $4.3 million as compared to the prior year period primarily due to increased sales prices. Operating cash flow and free cash flow in the first quarter of 2023 decreased $2.6 million as compared to the prior year period due to a higher quarterly distribution from Sisecam Wyoming in the first quarter of 2022.

International prices remained strong in the first quarter of 2023 reflecting a continued supply constrained market for soda ash. Domestic soda ash prices were also strong during the first quarter of 2023 versus the prior year quarter due to negotiated 2023 domestic prices converging to international soda ash prices.

Corporate and Financing

Corporate and Financing costs in the first quarter of 2023 decreased $5.2 million as compared to the prior year period primarily due to lower interest expense resulting from less debt outstanding. Operating cash flow and free cash flow in the first quarter of 2023 decreased $2.5 million as compared to the prior year period primarily due to increased cash paid for incentive compensation in the first quarter of 2023 because of the improved business performance in 2022 and higher cash paid for interest on credit facility borrowings in 2023.

In the first quarter of 2023, NRP received a notice from holders of the partnership's Class A Preferred Units exercising their right to either convert or redeem an aggregate of 47,499 Class A Preferred Units. NRP chose to redeem the preferred units for $47.5 million in cash rather than issuing common units. Of the originally issued 250,000 Class A Preferred Units, 202,501 Class A Preferred Units remain outstanding.

In February 2023, NRP declared and paid a fourth quarter 2022 cash distribution of $0.75 per common unit and a $7.5 million cash distribution on the preferred units. In March 2023, NRP declared and paid a special distribution of $2.43 per common unit to help cover unitholder tax liabilities associated with owning NRP's common units during 2022. Today, NRP declared a first quarter 2023 cash distribution of $0.75 per common unit and a $6.1 million cash distribution on its outstanding preferred units.

NRP's consolidated leverage ratio was 0.5x at March 31, 2023.

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 othersto 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 othersto assess our ability to make cash distributions and repay debt.

"Cash flow cushion" is a non-GAAP financial measure that we define as free cash flow less one-time beneficial items, mandatory Opco debt repayments, preferred unit distributions, redemption of preferred units, redemption of PIK units, common unit distributions, and warrant cash settlements. Cash flow cushion 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. Cash flow cushion is a supplemental liquidity measure used by our management to assess the Partnership's ability to make or raise cash distributions to our common and preferred unitholders and our general partner and repay debt or redeem preferred units.

"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.
