Natural Resource Partners (NYSE:NRP) reported fourth-quarter and full-year 2025 results marked by continued strong free cash flow generation despite what management described as exceptionally weak pricing across its key commodities: metallurgical coal, thermal coal, and soda ash.
Commodity backdrop remains challenging
President and Chief Operating Officer Craig Nunez said all three commodities “continue to struggle with sales prices that are near or below” operators’ marginal costs of production. He characterized metallurgical and thermal coal prices as “cyclically low,” while soda ash prices were described as “generational lows.” Management said it does not see near-term catalysts likely to improve the outlook.
On soda ash, Nunez said 2025 was “a very challenging time” for the global industry and that the partnership believes 2026 “will be worse.” He said international prices are currently below the cost of production for most producers and that supply rationalization is “not a question of if, but when,” while also cautioning that rebalancing could take years before prices return to historical levels.
Fourth-quarter and full-year results
Chief Financial Officer Chris Zolas reported that NRP generated $31 million of net income, $45 million of operating cash flow, and $46 million of free cash flow in the fourth quarter of 2025. For the full year 2025, the partnership generated $136 million of net income, $166 million of operating cash flow, and $169 million of free cash flow.
Zolas said the Mineral Rights segment delivered $40 million of net income, $49 million of operating cash flow, and $50 million of free cash flow in the fourth quarter, and $166 million of net income, $182 million of operating cash flow, and $185 million of free cash flow for the full year.
Compared with the prior-year period, Zolas said the Mineral Rights segment’s fourth-quarter net income, operating cash flow, and free cash flow each decreased by $13 million. For the full year, segment net income declined $41 million and operating and free cash flow each decreased $60 million, which he attributed primarily to weaker metallurgical coal markets that led to lower prices and volumes.
Zolas also provided the partnership’s coal royalty mix, noting that metallurgical coal represented about 70% of coal royalty revenues and 45% of coal royalty sales volumes in the fourth quarter. For the full year 2025, he said metallurgical coal accounted for about 65% of coal royalty revenues and 45% of coal royalty sales volumes.
For the Soda Ash segment, Zolas said net income declined $3 million in the fourth quarter and $15 million for the full year compared to the prior-year periods. Operating and free cash flow fell $11 million in the fourth quarter and $31 million for the full year, driven primarily by lower international prices, which he said were influenced by new natural soda ash supply from China, as well as weak glass demand from construction and automotive markets.
Sisecam Wyoming: distributions paused and capital investment planned
Management highlighted ongoing pressure at Sisecam Wyoming, the partnership’s soda ash joint venture. Nunez said NRP has not received distributions from the venture for the last two quarters and does not expect distributions to resume “for the foreseeable future,” as the managing partner retains cash for safety, operational integrity, and capital structure support.
Earlier in the month, Nunez said NRP agreed to invest capital in the venture to reduce outstanding amounts under its bank credit facility and improve competitiveness in the current market. NRP’s share of that investment is $39 million.
During the question-and-answer session, management said the joint venture is not debt-free following the contribution and will have more than $50 million of debt remaining afterward. Nunez said additional contributions are “not our plan right now,” though he added that if market conditions worsen, there could be situations where NRP would elect to contribute more capital. He also clarified the contribution was NRP’s “election,” not a requirement.
Zolas reiterated that the partnership has not received a distribution from Sisecam Wyoming since the second quarter of 2025 and said distributions are not expected to resume until soda ash demand rebounds or a significant supply response occurs, “most likely from higher cost synthetic production.”
Deleveraging progress and distribution update
Despite the difficult commodity environment, Nunez emphasized progress toward the partnership’s long-standing goal of retiring all debt. He said NRP retired $109 million of debt during 2025 and ended the year with $33 million of debt and “no other financial obligations outstanding.” Zolas said the Corporate and Financing segment improved versus prior periods due to lower interest costs from significantly reduced debt balances.
Nunez said the partnership had targeted retiring all debt and “significantly” increasing unitholder distributions in August 2026, but cautioned previously that prolonged bear markets could delay that timing. He said the $39 million Sisecam investment is one such event and will push the expected distribution increase into a subsequent quarter.
On the call, Nunez told an investor that the partnership does not anticipate being in a position to substantially increase distributions in the May quarter. Based on the partnership’s free cash flow run-rate and the timing of the Sisecam contribution, he said the timing “is probably in November,” while reiterating that a longer bear market could still push that timing back.
Zolas said NRP paid a $0.75 per common unit distribution for the third quarter of 2025 in November and paid another $0.75 per common unit distribution related to the fourth quarter of 2025 in February. He also said the partnership announced a special distribution of $0.12 per common unit to help cover unitholder tax liabilities associated with owning NRP common units in 2025.
Capital allocation and other initiatives
In response to a question about not bidding in a mineral rights auction related to Warrior mines, Nunez said auctions are typically not places where NRP finds attractive opportunities for mineral-type assets, and he emphasized the partnership’s ongoing focus on deleveraging and then returning capital to unitholders.
Elsewhere, Nunez said interest in leasing for underground carbon sequestration remains “lackluster” due to political, regulatory, and market uncertainties. He added that NRP continues to work on geothermal, solar, and lithium opportunities, with “small-scale progress” but nothing material to report.
