| Financial Overview Adjusted EBITDA* (in millions) Balance Sheet as of Sept. 30, 2013 Adjusted Net Income* (in millions) Earnings Per Share (Diluted) Cash and Investments $ 81 million Current Assets $ 188 million Total Assets $1,181 million Debt Outstanding $ 150 million Total Liabilities $ 242 million Stockholders’ Equity $ 939 million Availability Under Unsecured Credit Facility $ 250 million 20 * These are financial measurements not calculated based on U.S. Generally Accepted Accounting Principles (Non-GAAP). Non-GAAP reconciliations available in the appendix to this presentation.

| Non-GAAP Reconciliation Calculation of Adjusted EBITDA (in thousands) 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 add back of reductions in the estimated accounts receivable related to the employment-related high wage tax credits in New Mexico, interest expense (including derivatives), income tax expense, depreciation, depletion, and amortization, and asset retirement obligation accretion. Management believes that the presentation of adjusted EBITDA assists investors and analysts in comparing Intrepid's performance across reporting periods on a consistent basis by excluding items that management does not believe are indicative of the Company's core operating performance. Intrepid uses adjusted EBITDA as one of the tools to evaluate the effectiveness of its business strategies. In addition, adjusted EBITDA is widely used by professional research analysts and others in the valuation, comparison, and investment recommendations of companies in the potash mining industry, and many investors use the published research of industry research analysts in making investment decisions. Adjusted EBITDA should not be considered in isolation or as a substitute for performance or liquidity measures calculated in accordance with U.S. GAAP. Because adjusted EBITDA excludes some but not all items that affect net income and net cash provided by operating activities and may vary among companies, the adjusted EBITDA amounts presented may not be comparable to similarly titled measures of other companies. The following is a reconciliation of adjusted EBITDA to net income, which is the most directly comparable U.S. GAAP measure: 21 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Net Income $20,626 $19,013 $33,267 $14,537 $14,919 $11,317 $2,026 Add: Allowance for New Mexico employment credits 2,811 Add: Interest Expense, including realized and 253 215 221 216 213 219 248 unrealized derivative gains and/losses Add: Income tax expense 12,613 12,312 10,685 13,874 8,698 7,171 (350) Add: Depreciation, depletion, amortization and accretion 11,256 11,376 12,095 12,872 14,141 14,338 15,561 Total adjustments 24,122 23,903 23,001 26,962 23,052 21,728 18,270 Adjusted Earnings Before Income Taxes, Interest Depreciation, Depletion and Amortization $44,748 $42,916 $56,268 $41,499 $37,971 $33,045 $20,296 2012 2013 - - - - - -

| Non-GAAP Reconciliation Adjusted net income and adjusted net income per diluted share are non-GAAP financial measures that are calculated as net income or earnings per diluted share adjusted for certain items that impact comparability of results from period to period including, among other items, pension settlement expense, reductions in the estimated accounts receivable related to the employment-related high wage tax credits in New Mexico, lower of cost or market inventory adjustments, non-cash unrealized gains or losses associated with derivative adjustments, the recognition of the outcome of contingent gain items, and the effect of changes to Intrepid's state income tax rates on the value of its net deferred tax asset. Management believes that the presentation of adjusted net income and adjusted net income per diluted share provides useful additional information to investors for analysis of Intrepid's fundamental business on a recurring basis. In addition, management believes that the concept of adjusted net income and adjusted net income per diluted share are widely used by professional research analysts and others in the valuation, comparison, and investment recommendations of companies in the potash mining industry, and many investors use the published research of industry research analysts in making investment decisions. Adjusted net income and adjusted net income per diluted share should not be considered in isolation or as a substitute for net income or earnings per diluted share, income from operations, cash provided by operating activities or other income, profitability, cash flow, or liquidity measures prepared under U.S. GAAP. Because adjusted net income and adjusted net income per diluted share exclude some but not all items that affect net income and may vary among companies, the adjusted net income and adjusted net income per diluted share amounts presented may not be comparable to similarly titled measures of other companies. The following are reconciliations of adjusted net income to net income and adjusted net income per diluted share to earnings per diluted share, respectively, which are the most directly comparable U.S. GAAP measures: * Estimated effective tax rate of 36.2% for 2013 and 32.8% for 2012. 22 Calculation of Adjusted Net Income (in thousands) Q1 Q2 Q3 Q4 Q1 Q2 Q3 Net Income $20,626 $19,013 $33,267 $14,537 $14,919 $11,317 $2,026 Adjustments Insurance settlements from property and business losses - - - - - - - Allowance associated with New Mexico refundable employment-related credit - - - - - - 2,811 Unrealized derivative gain (224) (273) (272) (280) - - - Loss on settlement of pension obligation termination - - - - - 1,871 - Compensating tax refund - - - - - (1,705) - Other 330 (3) 181 60 8 4 2,080 Calculated tax effect* (40) 107 30 78 (3) (64) (1,771) Change in blended state tax rate to value deferred tax asset - - (4,290) 5,271 - 1,260 - Total adjustments 66 (169) (4,351) 5,129 5 1,366 3,120 Adjusted Net Income $20,692 $18,844 $28,916 $19,666 $14,924 $12,683 $5,146 2012 2013
