Natural Resource Partners L.P. Schedules Third Quarter 2022 Earnings Conference Call

Natural Resource Partners L.P. (NYSE:NRP) today reported third quarter 2022 results as follows:

Highlights:

• G   enerated record free cash flow of $83 million in the third quarter of 2022, and $199 million in the first nine months of 2022
• Closed new five-year, $130 million revolving credit facility
• Announced full repayment of outstanding 9.125% Senior Notes due 2025
• Executed second subsurface carbon dioxide ("CO ₂ ") sequestration lease
• Pro-forma leverage ratio of 0.6x following the repayment of 9.125% Senior Notes, down from 4.6x as of June 30, 2021

"NRP's record year continues with third quarter free cash flow generation of $83 million, bringing our year-to-date free cash flow to $199 million, primarily due to the strong results of our Mineral Rights segment," stated Craig Nunez, NRP's president and chief operating officer. "It is fitting that the 20th anniversary of the Partnership's initial public offering coincides with the best operating performance in our history. Not only has this year been exceptional from a free cash flow perspective, but we continue to execute on our strategy to de-risk the capital structure and grow our carbon neutral portfolio. During the third quarter, we closed a new five-year revolving credit facility that increased our borrowing capacity from $100 million to $130 million. We also announced the redemption of our outstanding 9.125% Senior Notes due 2025 and fully repaid the Senior Notes in October. After giving effect to the redemption, NRP has permanently retired $249 million of debt this year. In the third quarter we also executed our second subsurface CO ₂ sequestration lease for an estimated carbon storage capacity of at least 500 million metric tons of CO ₂ . NRP currently has approximately 140,000 acres of pore space under lease for carbon sequestration with estimated potential CO ₂ storage capacity of at least 800 million metric tons. We continue to believe that de-risking the Partnership and leveraging our asset footprint in this regard, while continuing to provide unitholder distributions, is the right strategy to maximize unitholder value."

NRP announced today that the Board of Directors of its general partner declared a cash distribution of $0.75 per common unit to be paid on November 22, 2022 to unitholders of record on November 15, 2022. In addition, the board declared a $7.5 million cash distribution on its 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 $190.9 million at September 30, 2022, consisting of $60.9 million of cash and $130.0 million of borrowing capacity available under its recently amended revolving credit facility.

Segment Performance

Mineral Rights

Mineral Rights net income for the third quarter of 2022 increased $35.6 million as compared to the prior year period. Free cash flow for the third quarter increased $42.0 million as compared to the prior year period. These increases were primarily due to stronger metallurgical coal demand and pricing in 2022. Approximately 65% of coal royalty revenues and approximately 40% of coal royalty sales volumes were derived from metallurgical coal in the third quarter of 2022.

Metallurgical and thermal coal prices remain supported by ongoing tightness in the supply-demand balance for coal. Many operators are limited in their ability to increase production due to ongoing labor shortages, global supply chain interruptions, and access to capital. Thermal coal prices are further supported by the European Union's ban on Russian coal due to the war in Ukraine, as well as increased natural gas prices and demand for electricity. While metallurgical markets are seeing weakened demand for steel, and thermal markets continue to face ongoing environmental and political pressures, supply constraints should provide continued support for metallurgical and thermal coal prices for the foreseeable future.

NRP continues to identify alternative revenue opportunities across its large portfolio of land and mineral assets. NRP owns the rights to sequester CO ₂ on approximately 3.5 million acres of pore space in the southern United States. As announced previously, in the first quarter of 2022 NRP executed its first subsurface CO ₂ sequestration lease on 75,000 acres of underground pore space NRP owns in southwest Alabama with the potential to store over 300 million metric tons of CO ₂ . In October of 2022, NRP announced its second subsurface CO ₂ transaction with the execution of a lease for approximately 65,000 acres of pore space controlled by NRP near southeast Texas with estimated storage capacity of at least 500 million metric tons of CO ₂ . In total, NRP has approximately 140,000 acres of pore space under lease for carbon sequestration with estimated CO ₂ storage capacity of 800 million metric tons. While the timing and likelihood of additional cash flows being realized from these activities is uncertain, NRP believes its large ownership footprint throughout the United States will provide additional opportunities to create value in this regard and position NRP as a key beneficiary of the transitional energy economy with minimal capital investment.

Soda Ash

Soda Ash net income in the third quarter of 2022 increased $7.9 million as compared to the prior year period primarily as a result of increased international sales prices. Free cash flow in the third quarter of 2022 increased $10.3 million as compared to the prior year period due to Sisecam Wyoming reinstating its regular quarterly cash distributions beginning in the fourth quarter of 2021.

Supply interruptions in China and input cost inflation which significantly increased the global marginal cost of soda ash production led to historically high soda ash prices in the third quarter of 2022. Though soda ash demand weakened in many parts of the world during the third quarter due to slowing global economic growth and lower construction activity in China, Sisecam Wyoming remained sold-out as it took advantage of its low-cost position to profitably export soda ash. Consequently, Sisecam Wyoming delivered strong financial results in the third quarter of 2022.

Corporate and Financing

Corporate and Financing costs in the third quarter of 2022 decreased $1.6 million as compared to the prior year period primarily due to lower interest expense resulting from less debt outstanding, partially offset by the loss on early extinguishment of debt. Free cash flow in the third quarter of 2022 was relatively flat as compared to the prior year period.

During the third quarter of 2022, NRP repaid $60.5 million of debt and refinanced, upsized, and extended its credit facility to $130 million due 2027. In October of 2022, NRP fully retired its outstanding $121.4 million of 9.125% Senior Notes due 2025 at its redemption price of 102.281%, utilizing cash on hand and $70 million of borrowings under its new credit facility. After giving effect to this redemption, NRP's remaining total debt outstanding is $189.4 million.

Additionally, in August of 2022, NRP paid a second quarter 2022 cash distribution of $0.75 per common unit of NRP and a $7.5 million cash distribution on the preferred units.

"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.

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 of continuing operations 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.
