No transcript in the pack.

1. What the business actually does

NRP is a master limited partnership owning roughly 13 million acres of mineral rights, leased to operators for royalties rather than mined itself. Two segments: Mineral Rights, meaning coal royalties (about 65% metallurgical in 2025) plus wheelage, oil and gas, aggregates and lease minimums; and Soda Ash, a 49% non-controlling stake in Sisecam Wyoming that NRP does not operate and monetizes only when distributions are paid (10-K 2025, Item 7). Screen capex is zero, and Mineral Rights turned $100.2M of H1 2026 revenue into $88.5M of Adjusted EBITDA (10-Q Q2 2026, Item 2).

2. Why it is mispriced — the edge case

Honestly, I cannot identify a dislocation, and that caps this at WATCH. The unit is 8.3% below its 52-week high with positive 12-1 momentum of 3.4% (screen row), and an insider sold 2,200 units at $110.89 on 2026-08-28 (Form 4). Nobody is forced out. What exists is a permanent structural discount rather than a temporary one: a K-1 partnership with 13.25 million units and $4.2M of daily volume is excluded from equity indices and creates UBTI for tax-exempt accounts. That is durable and already in the price. The one new and dated fact is management's statement that NRP is "on track to pay off all debt and significantly raise distributions before year-end" (8-K 2026-08-05, Nunez), language absent from the May release (8-K 2026-05-06).

The screen also flatters the name, reading CY2025 EBIT of $144.4M. True trailing operating income is about $111.7M (LTM net income $106.7M plus $5.0M interest, 8-K 2026-08-05), so real trailing EV/EBIT is 13.5x, not 10.3x.

3. Unit economics and growth

Revenue fell from $268.0M in 2024 to $207.3M in 2025 and Adjusted EBITDA from $235.5M to $164.1M, with LTM through June 2026 down again to $154.4M (10-K 2025, Item 7; 8-K 2026-08-05). The headline pricing decline overstates the damage. Combined coal royalty per ton was $4.25 in Q2 2026 against $5.17, down 18%, but Central Appalachia fell only 5% ($6.06 from $6.41) and Southern Appalachia rose 35% ($11.52 from $8.53); the average is dragged by Northern Appalachia volumes going from 132 to 1,492 thousand tons at a $1.18 royalty (10-Q Q2 2026, Item 2). That is mix, not collapse, and Q2 Mineral Rights revenue rose 11%.

Two real negatives. Lessee concentration is severe: Alpha was about 26% of 2025 revenues, Foresight 21% and Alabama Kanu's Oak Grove 11%, so three lessees are 58% (10-K 2025, Item 1A). And depletion jumped to $11.1M in Q2 2026 from $3.8M on "revised engineering and increased depletion rate at a thermal property," which management says does not change "the segment's long-term earning power" (8-K 2026-08-05). It is non-cash, but it is the accountant's estimate of how fast a finite asset is being consumed, and it tripled against a $351.5M carrying value.

4. Balance sheet and capital allocation

Debt is $27.4M of principal against $30.1M of cash and $217.0M of liquidity, leverage 0.2x; the partnership agreement restricts distributions above $0.45 per unit only above 3.25x, so nothing binds (10-Q Q2 2026, Item 2; 10-K 2025, Item 1A). Units grew 0.9% to 13,250k on award vesting, no buyback in evidence. The distribution has been $0.75 per quarter since 2024, plus a $1.21 special in March 2025 and $0.12 in March 2026 for unitholder tax liabilities (10-K 2025, Item 7). Governance is standard-bad MLP: unitholders cannot elect the board, GP removal needs 66 2/3%, holders above 20% lose their votes, and the GP can force out minorities at market once it holds 80% (10-K 2025, Item 1A). NRP has no employees; officers are paid by Quintana Minerals and Western Pocahontas, both Robertson affiliates, and reimbursed on time allocation. Robertson held 33.8% at 2017-12-01 (DEF 14C) and remains a flagged 10% owner with 763,658 units directly (Form 4, 2026-02-12).

5. Management: what they said versus what they did

The 2025 10-K said NRP did "not expect any material changes to pricing in 2026" (10-K 2025, Item 7), and Q2 revenue beat that by rising 11%, so they were conservative. Against that, in February 2026 they put $39.2M into Sisecam Wyoming while telling holders not to expect distributions from it "for several years" (8-K 2026-05-06). That cash call on an asset the partnership does not control turned $162.8M of LTM free cash flow into $123.6M actually retained (8-K 2026-08-05).

6. Valuation

LP free cash flow, taking 98% of the $162.8M LTM figure before the soda ash call across 13.25M units, is $12.04 per unit, a 10.6% yield.

Base, $115: coal royalties hold near the $129M H1 annualized rate, costs flat, no soda ash distributions or further calls, no interest after repayment. Free cash flow about $155M or $11.55 per unit, paying out 85% at an 8.5% yield. Bear, $75: per-ton royalties fall another 15% on flat volumes and one more $40M Sisecam call arrives, free cash flow to $125M or $9.25 per unit, demanded return 12% on a depleting coal stream. Bull, $180: metallurgical realizations recover toward 2024, coal royalties back to $159.0M and Adjusted EBITDA toward $235.5M, soda ash resumes distributions (2024 receipts $38.8M), free cash flow near $200M or $14.80 per unit at an 8% yield. Weighted 30/45/25 gives about $119, roughly 5% above the price. Reverse DCF: at $113.40 for $12.04 per unit, the price implies flat cash flow running about 18 years and then stopping if you discount at 8%, about 30 years at 10%, or forever at 10.6%.

7. Catalysts and timeline

Q3 results in early November 2026 should show debt at or near zero. The Q4 2026 distribution declared in February 2027, alongside the annual tax special, is the actual test of the "significantly raise" promise. Any resumption of Sisecam distributions is a multi-year option, not a 2027 event.

8. Kill criteria (pre-registered)

1. The Q4 2026 distribution declared in February 2027 is not raised above $0.75 per unit, or debt is not zero at year end.
2. A further Sisecam capital contribution above $25M, or a writedown of the $277.5M carrying value by more than 20%.
3. Combined coal royalty revenue per ton below $4.00 for two consecutive quarters.
4. LTM free cash flow before soda ash investment below $130M.

9. Verdict and one-paragraph summary

WATCH, conviction 3. NRP is a zero-capex royalty book that converted 88% of H1 revenue into Adjusted EBITDA, carries 0.2x leverage, and will be debt-free by year-end, with management stating on August 5 that it will then "significantly raise distributions." None of that is hidden: the unit sits 8% off its 52-week high on positive momentum, no forced seller exists, and my probability-weighted value of about $119 is only 5% above the $113.40 price. The screen's 10.3x EV/EBIT is stale CY2025 arithmetic and the real trailing figure is 13.5x, because depletion at one thermal property tripled and soda ash swung to a $16.8M LTM loss. The 10.8% free cash flow yield is also pre-capital-call: $39.2M went into a 49% stake that will pay nothing for years, cutting the realized yield to 8.1%. It is a watch rather than a pass because February 2027 is a dated test of whether the raised distribution actually appears.
