Ingredients for Growth November 2014

This presentation contains forward-looking statements — that is, statements about future, not past, events. These forward-looking statements often relate to our future performance and management’s expectations for the future, including statements about our financial outlook. Our forward-looking statements are based on estimates and assumptions that we believe are reasonable. Actual results could be materially different from our forward-looking statements. The factors that could cause actual results to differ are discussed in our periodic filings with the Securities and Exchange Commission. Statements regarding our financial outlook speak only as of the date of our third quarter 2014 earnings release, October 29, 2014, and all other forward-looking statements speak only as of the initial release date of this presentation, November 10, 2014. We have no duty to update publicly or revise any forward-looking statements to conform the statements to actual results or to reflect new information or future events. Safe Harbor 2

Intrepid Overview Building on Our History of Value Creation 3 Optimizing new and upgraded assets Created opportunity to increase per ton margin and cash flow Creating a stronger Intrepid Completed multi-year modernization program Expanding low cost solar solution mining Close-to-market strategy

Intrepid’s Unique Position Participating in industry with strong fundamentals Geographically advantaged assets Value enhancing logistics strategy Serving diverse customers and markets Leveraging solar solution mining expertise Benefitting from a prudent capital structure Highest average net realized sales price among North American competitors 4

Intrepid generates strong cash margins through its net realized price advantage YTD Sep. 30 33% Note: Average net realized sales price per ton is a non-GAAP financial measure calculated as gross sales less freight costs, divided by the number of tons sold in the period. Average net realized sales price advantage is a non-GAAP financial measure calculated by us as the difference between our average net realized sales price and the combined estimated average net realized sales prices of Potash Corporation of Saskatchewan Inc. (POT), The Mosaic Company (MOS), and Agrium Inc. (AGU) based on publicly available information and Intrepid estimates. See the non-GAAP reconciliations set forth later in this presentation for additional information.

Leveraging Solar Solution Mining Expertise Intrepid is a Leader in Solar Solution Mining Inject brine into idled or created mine works Allow brine to circulate to dissolve the remaining potash Extract potash enriched brine and pump into solar evaporation pond • Low per ton cash operating cost • Creative use of idled mine works and use of mother nature’s “free” energy • Intrepid’s assets are located in geographies conducive to solar evaporation Allow solar evaporation to occur; potash recrystallizes as water evaporates Harvest the potash from the evaporation ponds Mill the product and have it ready for our customer 8

Leveraging Solar Solution Mining Expertise HB Drives Cash Margin Opportunity • Expected cash margin per ton from HB approximately double • Combined cash operating costs improve 9% • Potential to grow cash margin faster than production growth 9 Note: Calculation assumes cash operating cost per ton for Current Potash State of $195, which was the full year 2013 result. HB cash operating cost per ton is assumed to be $90, the midpoint of the predicted range of $80-$100 per ton based on full production rates of 150,000 to 200,000 tons annually. Per ton cash operating cost is a non-GAAP financial measure that is calculated as total of cost of goods sold divided by the number of tons of potash sold and then adjusted to exclude per-ton royalties and per-ton depreciation, depletion, and amortization. Total cost of goods sold is reported net of by-product credits and does not include warehouse and handling costs. See the non-GAAP reconciliations set forth later in this presentation for additional information. Pro Forma Potash Combined assumes 825,000 tons of production from non-HB assets and the mid-point of the 150,000 to 200,000 tons of annual forecast production from HB. Cash margin per ton is a non-GAAP financial measure that is calculated as average net realized sales price less cash operating costs, royalties, warehousing and handling. $'s per ton Current Potash State Expected HB Solar Contribution Pro Forma Potash Combined Q3 2014 Average net realized sales price 336 $ 336 $ 336 $ Cash operating costs 195 90 177 Royalties, warehousing and handling 29 29 29 Cash margin per ton 112 $ 217 $ 130 $ Cash margin per ton 33% 65% 39%

See the non-GAAP reconciliations set forth later in this presentation for additional information

Non-GAAP Reconciliations To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use several non-GAAP financial measures to monitor and evaluate our performance. These non-GAAP financial measures include adjusted net income (loss), adjusted net income (loss) per diluted share, adjusted EBITDA, net sales, average net realized sales price, cash operating costs, average potash and Trio® gross margin, and free cash flow. 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, our non-GAAP financial measures may not be comparable to similarly titled measures used by other companies.  We believe these non-GAAP financial measures provide useful information to investors for analysis of our business. We also refer to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. We believe these non-GAAP financial measures are widely 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. On the following slides is additional information about our non-GAAP financial measures, including, if applicable, reconciliations of our non-GAAP financial measures to the most directly comparable GAAP measures:

Non-GAAP Reconciliation Adjusted earnings before interest, taxes, depreciation, and amortization (or adjusted EBITDA) is a non-GAAP financial measure that is calculated as net income adjusted for the reversal of the allowance associated with the employment-related high wage tax credits in New Mexico, restructuring expenses, interest expense, income tax expense (benefit), depreciation, depletion, and amortization, and asset retirement obligation accretion. We consider adjusted EBITDA to be useful because it reflects our operating performance before the effects of certain non-cash items and other items that we believe are not indicative of our core operations. We use adjusted EBITDA to assess operating performance and as one of the measures under our performance-based compensation programs for employees. Calculation of Adjusted EBITDA  In thousands 21

Non-GAAP Reconciliation Net sales, average net realized sales price, and average net realized sales price advantage are non-GAAP financial measures.  Net sales are calculated as sales less freight costs.  Average net realized sales price is calculated as net sales, divided by the number of tons sold in the period.   Average net realized sales price advantage is calculated by us as the difference between our average net realized sales price and the combined estimated average net realized sales prices of Potash Corporation of Saskatchewan Inc. (POT), The Mosaic Company (MOS), and Agrium Inc. (AGU) based on publicly available information.  We consider these measures to be useful because they remove the effect of transportation and delivery costs on sales and pricing.  When we arrange transportation and delivery for a customer, we include in revenue and in freight costs the costs associated with transportation and delivery.  However, many of our customers arrange for and pay their own transportation and delivery costs, in which case these costs are not included in our revenue and freight costs.  We use these measures as key performance indicators to analyze sales and price trends.  We also use net sales as one of the measures under our performance-based compensation programs for employees.

Non-GAAP Reconciliation Cash operating costs is a non-GAAP financial measure that is calculated as total of cost of goods sold divided by the number of tons sold in the period and then adjusted to exclude per-ton depreciation, depletion, and royalties. Total cost of goods sold is reported net of by-product credits and does not include warehouse and handling costs. We consider cash operating costs to be useful because it represents our core, per-ton costs to produce potash. We use cash operating costs as an indicator of performance and operating efficiencies and as one of the measures under our performance-based compensation programs for employees. 23 Potash Cash Operating Costs Per Ton 2013 Cost of goods sold 179,207 $ Divided by sales volume (in thousands of tons) 692 Cost of goods sold per ton 260 $ Less per-ton adjustments - Depreciation and depletion 52 Royalties 13 Cash operating costs per ton 195 $ In thousands, except per ton amounts
