INTREPID’s reserve summary Reserve Summary (1) Intrepid’s reserves in aggregate contain ~77 million tons of potash and ~57 million tons of langbeinite Long reserve lives provide opportunity for long-term operations 28 Source: Intrepid’s Annual Report on Form 10-K for the year ended December 31, 2016, filed on February 28, 2017 (2) The reserves associated with the Wendover solar evaporation mine reflect the combination of a shallow and a deep aquifer. There were no proven reserves reported for either aquifer because the shallow aquifer represents an unconventional resource and there is uncertainty of the hydrogeology of the deep aquifer. Accordingly, Intrepid agreed with the SEC in 2008 to report the life of the mine as being equal to 30 years. (tons in thousands) Proven Probable Product/ Date Mine Extraction Min.

Non-GAAP Reconciliations To supplement the Company's condensed consolidated financial statements, which are prepared and presented in accordance with GAAP, the Company uses several non-GAAP financial measures to monitor and evaluate its performance. These non-GAAP financial measures include adjusted net loss, adjusted net 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, the Company's non-GAAP financial measures may not be comparable to similarly titled measures used by other companies. The Company believes these non-GAAP financial measures provide useful information to investors for analysis of its business. The Company uses these non-GAAP financial measures as one of its tools in comparing performance period over period on a consistent basis and when planning, forecasting, and analyzing future periods. The Company believes 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. Following is additional information about the Company's non-GAAP financial measures, including reconciliations of the Company's non-GAAP financial measures to the most directly comparable GAAP measures. 34

Adjusted net loss and adjusted net loss per diluted share are calculated as net loss or 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. The Company considers these non-GAAP financial measures to be useful because they allow for period-to-period comparisons of the Company's operating results excluding items that the Company believes are not indicative of its fundamental ongoing operations.

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

Average net realized sales price per ton is calculated as sales, less freight costs, divided by the number of tons sold in the period. The Company considers average net realized sales price per ton to be useful because it shows average per-ton pricing without the effect of certain transportation and delivery costs. When the Company arranges transportation and delivery for a customer, it includes in revenue and in freight costs the costs associated with transportation and delivery. However, many of the Company's customers arrange for and pay their own transportation and delivery costs, in which case these costs are not included in the Company's revenue and freight costs. The Company uses average net realized sales price per ton as a key performance indicator to analyze sales and pricing trends.
