Reporting Period: Fiscal year ended December 31, 2025
Business Overview: NRP is a publicly traded Delaware limited partnership that owns, manages, and leases a diversified portfolio of mineral properties in the United States. The company operates through two primary segments: Mineral Rights (approximately 13 million acres of mineral interests, primarily coal) and Soda Ash (a 49% non-controlling equity interest in Sisecam Wyoming LLC, a trona ore mining and soda ash production business).

Material Changes vs. Prior Period
- Revenue Decline: Total revenues decreased by 23% ($60.7 million) compared to 2024.
- Mineral Rights: Revenues fell 18% ($45.7 million) primarily due to lower metallurgical coal sales prices and volumes, and the absence of one-time carbon neutral revenues received in 2024.
- Soda Ash: Revenues plummeted 83% ($15.1 million) due to significantly lower soda ash sales prices and reduced cash distributions from Sisecam Wyoming.
- Profitability: Net income decreased by 26% ($47.3 million) driven by the revenue declines, partially offset by lower operating and interest expenses.
- Debt Reduction: Total debt decreased significantly from $142.1 million in 2024 to $33.1 million in 2025, resulting in a leverage ratio of 0.2x.
- Coal Production: Total coal sales volumes increased 5% to 29.2 million tons, but the combined average coal royalty revenue per ton dropped 20% to $4.58.
Guidance, Outlook, and Risks
Management Commentary and Outlook:
- Coal Market: Metallurgical and thermal coal prices remained weak in 2025 due to sluggish steel demand and low natural gas prices. Management does not expect material pricing changes in 2026.
- Soda Ash Market: The market remains significantly oversupplied, with prices below the cost of production for many producers. Distributions from Sisecam Wyoming were suspended in Q3 and Q4 2025 and are not expected to resume for several years until high-cost capacity retires.
- Capital Investment: In February 2026, NRP and its partner agreed to invest an additional $39.2 million (NRP's 49% share) into Sisecam Wyoming to reduce its bank credit facility and improve competitiveness.
- Distributions: NRP paid a quarterly distribution of $0.75 per unit for Q4 2025 and announced a special distribution of $0.12 per unit in March 2026 to assist with unitholder tax liabilities.
Key Risks and Contingencies:
- Commodity Price Volatility: Revenues are highly sensitive to coal and soda ash prices, which are subject to global economic conditions and trade regulations.
- Customer Concentration: Three lessees (Alpha Metallurgical Resources, Foresight, and Alabama Kanu) accounted for approximately 58% of total revenues in 2025.
- Regulatory Environment: Climate change legislation, emissions regulations (e.g., EPA rules on GHG and air pollutants), and environmental laws could restrict coal production and increase costs for lessees.
- Sisecam Wyoming Control: NRP has limited approval rights regarding Sisecam Wyoming's operations, distributions, and capital expenditures, exposing the partnership to operating risks it does not control.
Investor Verification Checklist
- Soda Ash Distribution Resumption: Verify the timeline and conditions under which Sisecam Wyoming expects to resume cash distributions, given the current oversupply and price environment.
- Coal Price Trends: Monitor metallurgical and thermal coal price forecasts for 2026 to assess the sustainability of royalty revenues.
- Lessee Financial Health: Review the financial stability of major lessees (Alpha, Foresight, Alabama Kanu) given the high concentration of revenue.
- Debt Covenants: Confirm continued compliance with debt covenants, specifically the leverage ratio (currently 0.2x vs. 3.0x limit) and interest coverage ratio.
- Regulatory Impact: Assess the potential impact of recent EPA rule changes regarding GHG emissions and the "Endangerment Finding" rescission on long-term coal demand.
