Denver, CO, November 5, 2025 - Intrepid Potash, Inc. ("Intrepid", "the Company", "we", "us", or "our") (NYSE:IPI) today reported its results for the third quarter of 2025.

Full realization of first half 2025 price increases, steady demand for potash and Trio®, and solid unit economics led to another quarter of strong financial results, highlighted by:

•Total sales of $53.2 million;

•Net income of $3.7 million, or $0.28 per diluted share;

•Adjusted net income(1) of $1.5 million, or $0.11 per diluted share; and

•Adjusted EBITDA(1) of $12.0 million;

Kevin Crutchfield, Intrepid's Chief Executive Officer, commented: "We delivered another quarter of solid financial results and I want to thank our entire team for their commitment to safety and hard work. Our third quarter net income of $3.7 million and adjusted EBITDA of $12.0 million brings our respective year-to-date figures to $12.6 million and $45.0 million, which except for the record pricing in 2022, is the best performance since 2015.

Although our third quarter potash and Trio® sales volumes experienced normal seasonality, we saw pricing for both products move higher as we captured the entirety of first half price increases, which drove higher gross margins compared to the prior year. Trio® continues to be a clear standout for the Company, and we had another quarter of improved production, lower unit costs, and significant margin improvements.

•HB Solar Solution Mine in Carlsbad, New Mexico

◦AMAX Cavern: We are proceeding with our evaluation of the AMAX Cavern project and are pursuing the necessary permits to drill the injection well and install the pipeline to tie AMAX into the HB cavern system. We expect to have the permits in place by the end of the first quarter of 2026.

•Conventional Underground East Mine in Carlsbad, New Mexico

◦East Mine: We continue to see strong operating efficiencies and higher production at our East Mine, and we expect to place another relatively new continuous miner into service in the first quarter of 2026. As such, we expect higher Trio® production rates of approximately 70 to 75 thousand tons per quarter in 2026.

•In the third quarter of 2025, our capital expenditures totaled $7.7 million, bringing our year-to-date total to $20.2 million. We now expect our 2025 capital expenditures will be in the range of $30 to $34 million. Our 2025 spend includes approximately $5.0 million related to the HB AMAX Cavern, with the balance of our capital spend directed to sustaining projects across our potash and Trio® operations.

•As of October 31, 2025, our cash and cash equivalents totaled $74 million and we had no outstanding borrowings on our $150 million revolving credit facility that matures in August 2027.

In the third quarter of 2025, our potash segment sales increased $4.1 million compared to the same prior year period. This was primarily driven by a 15% increase in our potash sales volumes to 62 thousand tons and a 7% increase in our average net realized sales price per ton(1) to $381.

We sold more tons of potash compared to the same prior year period owing to a 15% increase in production over the last twelve months. Our average net realized sales price per ton increased compared to the prior year as Midwest warehouse prices increased throughout the first half of the year owing to resilient U.S. potash demand, which was supported by an increase in planted corn acres in 2025, as well as solid global potash market fundamentals.

In the third quarter of 2025, our potash production of 41 thousand tons was 10 thousand tons lower than the same prior year period, as we delayed production at our HB facility for approximately three weeks to maximize late season evaporation. Despite the above average rainfall at HB this summer, our focus on operational efficiencies and cost discipline led to an improvement in our potash segment cost of goods sold ("COGS") per ton, which totaled $340 in the third quarter of 2025. This compares to $348 per ton in the third quarter of 2024 and $337 per ton in the second quarter of 2025.

Our segment gross margin increased by $2.2 million compared to the same prior year period, which was primarily driven by the higher sales volumes and pricing.

Trio®

In the third quarter of 2025, Trio® segment sales decreased $1 million, or 4% compared to the same prior year period. Our Trio® sales decreased due to a 20% decrease in tons sold to 36 thousand tons, which was partially offset by a 29% increase in our average net realized sales price per ton(1) to $402.

The decrease in our Trio® sales volumes in the third quarter of 2025 was attributable to two factors: first, our Trio® demand was heavily weighted to the first half of 2025, where we sold a record 181 thousand tons; and second, normal seasonality as customers focused exclusively on third quarter application needs. Our Trio® average net realized sales price increased as first half price increases were fully realized and further supported by strengthening sulfate and potassium components of Trio® during the spring season. More specifically, sulfate products were in tight supply throughout the spring, but we do expect this to moderate as we end the year.

We continue to see strong efficiencies and lower operating expenses related to the continuous miners we commissioned, as well as from last year's restart of our fine langbeinite recovery system. Our Trio® production of 70 thousand tons represents an increase of eight thousand tons compared to the same prior year period, while our Trio® segment COGS per ton totaled $257, which compares to $272 per ton in the third quarter of 2024, and $235 per ton in the second quarter of 2025. Our third quarter 2025 COGS per ton increased compared to the second quarter of 2025 due to a higher mix of premium Trio® sales, which have higher associated costs, as well as lower sales volumes.

Our Trio® segment generated gross margin of $4.4 million in the third quarter of 2025, which compares to $0.6 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.

In the third quarter of 2025, our oilfield solutions segment sales decreased $7.6 million compared to the same prior year period, which was driven by a $7.4 million decrease in water sales. Our water sales reflect lower oilfield activity on and around the Intrepid South Ranch, as well as from lower sales on our Caprock well system, while our third quarter of 2024 also had the largest frac job in company history. Our surface use and easement revenues fluctuate based on the timing of recognizing revenue from the various performance obligations contained in the underlying agreements, which also contributed to the decrease in our third quarter 2025 revenue.

In the third quarter of 2025, our COGS decreased by $4.5 million compared to the same prior year period, which was primarily attributable to reduced purchases of third party water. We had a segment gross deficit of $60 thousand, which represents a decrease of $3.1 million, due to the factors discussed above.

1 Adjusted net income (loss), adjusted net income (loss) 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 (loss), adjusted net income (loss) 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 (loss) and adjusted net income (loss) per diluted share are calculated as net income (loss) or net income (loss) 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% and 26% for 2025 and 2024, respectively.

Adjusted earnings before interest, taxes, depreciation, and amortization (or adjusted EBITDA) is calculated as net income (loss) 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.
