Denver, CO, May 6, 2026 - Intrepid Potash, Inc. ("Intrepid", "the Company", "we", "us", or "our") (NYSE:IPI) today reported its results for the first quarter of 2026.

Supportive prices, resilient demand for potash and Trio®, and continued improvement in Trio® margins led to another quarter of strong financial results, highlighted by:

•Sales from continuing operations of $98.7 million;

•Net income from continuing operations of $6.9 million, or $0.52 per diluted share;

•Adjusted net income from continuing operations(1) of $8.2 million, or $0.62 per diluted share; and

•Adjusted EBITDA(1) of $19.0 million.

Kevin Crutchfield, Intrepid's Chief Executive Officer, commented: "We started 2026 with a great quarter and I want to thank our entire team for their commitment to safety and hard work. Our first quarter net income from continuing operations of $6.9 million and adjusted EBITDA of $19.0 million validates our focus on consistent execution across our core fertilizer business.

Combined potash and Trio® sales volumes were 211 thousand tons, our second highest quarterly sales total since idling the West mine in 2016. Trio® continues to be our strongest segment, as we posted the highest quarterly margin for the segment since 2022. Prices remained supportive in the spring and our investments in operational efficiency showed their worth as per-ton costs improved 5% compared to Q4.

•On April 1, 2026, we sold the majority of the assets of the Intrepid South Ranch to HydroSource Logistics LLC. As total consideration, Intrepid received a payment of $70 million, which includes an $8 million dollar deposit we received in December 2025. The sale of the South Ranch included approximately 21,793 acres of fee land; 27,858 acres associated with federal grazing leases; water rights located on the ranch; and various other assets, interests, and related agreements. The assets comprised the majority of the operations in our oilfield solutions segment, therefore oilfield solutions is no longer considered a reportable segment, and results from South Ranch operations prior to the sale are reported as discontinued operations.

•In early 2026, we commissioned a new continuous miner at our East Mine which has already improved operational efficiencies and increased Trio® production. Moreover, we also increased our operating hours per shift and continue to make operational improvements in our mill, both of which will also help drive higher production. We have realized the benefit of these improvements in Q1 through increased production of

granular and premium products. For FY 2026, we expect to produce 285 to 300 thousand tons of Trio®.

•Our partners continue to advance FEL-3 engineering and associated permitting. We look forward to providing further detail as it becomes available later in the year.

•In the first quarter of 2026, our capital expenditures totaled $5.1 million. We expect our 2026 capital expenditures will be in the range of $40 to $50 million.

•As of March 31, 2026, our cash and cash equivalents totaled $99.3 million and we had no outstanding borrowings on our $150 million revolving credit facility that has been extended to mature in March 2031.

In the first quarter of 2026, our potash segment sales increased $2.5 million compared to the same prior year period. This was primarily driven by a 13% increase in our average net realized sales price per ton(1) to $353, as 2026 winter fill prices were $40 per ton higher than the 2025 winter fill program.

In the first quarter of 2026, our potash production of 104 thousand tons was 11 thousand tons higher than the same prior year period, as we benefited from efficiency improvements across all our mines. Increased production from our higher-cost sites led to an increase in our average potash segment cost of goods sold ("COGS") per ton, which totaled $334 in the first quarter of 2026. This compares to $313 per ton in the first quarter of 2025 and $332 per ton in the fourth quarter of 2025.

Our segment gross margin increased by $0.6 million compared to the same prior year period, which was primarily a result of higher sales pricing partially offset by higher costs on a similar volume.

In the first quarter of 2026, we recorded $0.8 million in lower of cost or net realizable value inventory adjustments for certain potash products as our weighted average carry cost per ton exceeded our expected net realizable value per potash ton for certain products. In first quarter of 2025, we recorded $1.3 million in lower of cost or net realizable value inventory adjustments

Trio®

In the first quarter of 2026, Trio® segment sales increased $2.7 million, or 5% compared to the same prior year period. This was largely driven by a 12% increase in our average net realized sales price per ton(1) to $387 due to continued supportive prices of the individual nutrient components of Trio®, particularly sulfate and potassium, partially offset by a 4% decline in tons sold.

Our Trio® production of 69 thousand tons was 10% higher than the first quarter last year despite weather-related production interruptions early in the quarter, showing the benefit of the new continuous miner commissioned earlier this year and ongoing plant optimization projects. Our Trio® segment COGS per ton totaled $229, which compares to $235 per ton in the first quarter of 2025, and $242 per ton in the fourth quarter of 2025.

Our Trio® segment generated gross margin of $14.8 million in the first quarter of 2026, which compares to $10.4 million in the same prior year period, with the increase primarily attributable to the higher average net realized sales price per ton, as well as an improvement in our Trio® segment COGS per ton, which helped offset a slight decline in sales volume.

1 Adjusted net income from continuing operations, adjusted net income from continuing operations per diluted share, adjusted earnings before interest, taxes, depreciation, and

amortization (or adjusted EBITDA) and average net realized sales price per ton are non-GAAP financial measures. See the non-GAAP reconciliations set forth later in this press release for additional information.

Unless expressly stated otherwise or the context otherwise requires, references to tons in this press release refer to short tons. One short ton equals 2,000 pounds. One metric tonne, which many international competitors use, equals 1,000 kilograms or 2,204.62 pounds.

To supplement Intrepid's consolidated financial statements, which are prepared and presented in accordance with GAAP, Intrepid uses several non-GAAP financial measures to monitor and evaluate its performance. These non-GAAP financial measures include adjusted net income, adjusted net income per diluted share, adjusted EBITDA, and average net realized sales price per ton. These non-GAAP financial measures should not be considered in isolation, or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. In addition, because the presentation of these non-GAAP financial measures varies among companies, these non-GAAP financial measures may not be comparable to similarly titled measures used by other companies.

Intrepid believes these non-GAAP financial measures provide useful information to investors for analysis of its business. Intrepid uses these non-GAAP financial measures as one of its tools in comparing period-over-period performance on a consistent basis and when planning, forecasting, and analyzing future periods. Intrepid believes these non-GAAP financial measures are used by professional research analysts and others in the valuation, comparison, and investment recommendations of companies in the potash mining industry. Many investors use the published research reports of these professional research analysts and others in making investment decisions.

Adjusted net income and adjusted net income per diluted share are calculated as net income or net income per diluted share adjusted for certain items that impact the comparability of results from period to period, as set forth in the reconciliation below. Intrepid considers these non-GAAP financial measures to be useful because they allow for period-to-period comparisons of its operating results excluding items that Intrepid believes are not indicative of its fundamental ongoing operations.

(1) Assumes an annual effective tax rate of 0% for 2026 and 2025.

Adjusted earnings before interest, taxes, depreciation, and amortization (or adjusted EBITDA) is calculated as net income from continuing operations adjusted for certain items that impact the comparability of results from period to period, as set forth in the reconciliation below. Intrepid considers adjusted EBITDA to be useful, and believe it to be useful for investors, because the measure reflects Intrepid's operating performance before the effects of certain non-cash items and other items that Intrepid believes are not indicative of its core operations. Intrepid uses adjusted EBITDA to assess operating performance.

Average Potash and Trio® Net Realized Sales Price per Ton

Average net realized sales price per ton for potash is calculated as potash segment sales less potash segment byproduct sales and potash freight costs and then dividing that difference by the number of tons of potash sold in the period. Likewise, average net realized sales price per ton for Trio® is calculated as Trio® segment sales less Trio® segment byproduct sales and Trio® freight costs and then dividing that difference by Trio® tons sold. Intrepid considers average net realized sales price per ton to be useful, and believe it to be useful for investors, because it shows Intrepid's potash and Trio® average per ton pricing without the effect of certain transportation and delivery costs. When Intrepid arranges transportation and delivery for a customer, it includes in revenue and in freight costs the costs associated with transportation and delivery. However, some of Intrepid's customers arrange for and pay their own transportation and delivery costs, in which case these costs are not included in Intrepid's revenue and freight costs. Intrepid uses average net realized sales price per ton as a key performance indicator to analyze potash and Trio® sales and price trends.

(1) Depreciation, depletion, and amortization incurred for potash and Trio® excludes depreciation, depletion, and amortization amounts absorbed in or relieved from inventory.
