Overview

Our Company

We are the largest producer of muriate of potash ("potassium chloride" or "potash") in the United States and are dedicated to the production and marketing of potash and langbeinite ("sulfate of potash magnesia"), another mineral containing potassium. Our revenues are generated exclusively from the sale of potash and langbeinite. We market our langbeinite under the name of Trio™. Potassium is one of the three primary nutrients essential to plant formation and growth. We are one of two producers of langbeinite, a low-chloride fertilizer that is well-suited for chloride-sensitive crops and has the added benefit of magnesium. We also produce salt, magnesium chloride, and metal recovery salts from our potash mining processes, the sales of which are accounted for as by-product credits to our cost of sales. We own five active potash production facilities-three in New Mexico (referenced collectively below as "Carlsbad" or individually as "West," "East," and "North") and two in Utah ("Moab" and "Wendover")-and we have the nameplate capacity to produce 1,200,000 short tons of potash and 250,000 short tons of langbeinite annually. We own two development assets in New Mexico-the HB mine, which is an idled potash mine that we are in the process of reopening as a solution mine that will utilize solar evaporation techniques in the production of potash, and the North Mine, which was operated as a traditional underground mine until the early 1980s. Since 2005, we have supplied, on average, approximately 1.6 percent of world potash consumption and 9.4 percent of U.S. consumption annually.

We routinely post important information about us on our website under the Investor Relations tab. Our website address is www.intrepidpotash.com.

Our asset base was built through the acquisition first of the Moab operations in 2000, and then the Wendover and Carlsbad operations in 2004. We assembled these assets after observing that the Moab mine sold potash into the same geographic regions as the Carlsbad, New Mexico and Wendover, Utah mines. We recognized that acquiring assets in those areas could allow for consolidated marketing efforts and effect operating synergies.

Intrepid was incorporated in the state of Delaware on November 19, 2007, for the purpose of continuing the business of Mining in corporate form after Intrepid's initial public offering ("IPO"). On April 25, 2008, Intrepid closed its IPO by selling 34,500,000 shares of common stock at $32.00 per share. Net proceeds of the offering were approximately $1.032 billion after underwriting discounts and commissions and transaction costs. Prior to April 25, 2008, Intrepid was a consolidated subsidiary of Mining, its predecessor. Since April 25, 2008, Mining's ongoing business has been conducted by Intrepid and includes all operations that previously had been conducted by Mining. On April 25, 2008, pursuant to the Exchange Agreement, Mining assigned all of its assets other than approximately $9.4 million of cash to Intrepid in exchange for 40,339,000 shares of Intrepid's common stock and approximately $757.4 million of the net proceeds of the IPO. In connection with the exercise of the underwriters' over-allotment option, Intrepid also distributed to Mining approximately $135.4 million on April 25, 2008. For more information concerning our IPO and Formation Transactions, please see the section entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations"-Overview-Our Company contained in our Annual Report filed on Form 10-K for the year ended December 31, 2008.

Presentation of Information

The activity presented for and after April 25, 2008, is for Intrepid, and the period presented prior to April 25, 2008, relates to Mining as the predecessor entity. The results of operations data for the three months ended September 30, 2009 and 2008, the nine months ended September 30, 2009, the period April 25, 2008, through September 30, 2008 (the successor period), and the balance sheet data as of September 30, 2009, presented herein, were derived from the unaudited consolidated financial

results of Intrepid. Balance sheet data as of December 31, 2008, was derived from Intrepid's audited consolidated financial statements. The results of operations data for the period from January 1, 2008, through April 24, 2008 (the predecessor period), presented herein, were derived from the historical financial statements of Mining. The financial statements for the predecessor period give effect to identified revenues, estimated expenses, discrete events, substantiation of assets and liabilities and other methods management considered to provide a reasonable reflection of the results for such period. The historical financial data of Mining may not be indicative of Intrepid's future performance nor will such data reflect what Intrepid's financial position and results of operations would have been had Mining operated as an independent, publicly-traded company during the historical periods presented.

Pro forma consolidated results of operations data are presented and discussed within this management's discussion and analysis to provide meaningful information for comparison purposes. Analytical information for the non-comparative period will be discussed and analyzed where meaningful information is deemed to exist and will be presented in the position of greatest prominence. We will additionally provide comparative analytical discussion about the nine month comparative period ended September 30, 2009, on a pro forma basis consistent with the form and content standards set forth in Article 11-02(b) of Regulation S-X under the Securities Exchange Act of 1934, as amended. The pro forma adjustments to the nine month period ended September 30, 2008, relate only to additional expense associated with stock compensation expense, adjustments to reduce interest expense resulting from the repayment of debt, income taxes provided at the statutory rate for the period related to Mining since it was a limited liability company plus the aggregate impact of pro forma adjustments, and for any adjustments associated with weighted average common shares used in the calculation of both basic and diluted earnings per share. Because the same assets were utilized in Mining and Intrepid before and after Intrepid's IPO and since there was no material activity in Intrepid from its formation in November 2007 until the closing of the IPO on April 25, 2008, there are no adjustments necessary to the production or sales results of the period related to Mining in order to create a comparative presentation for the nine months ended September 30, 2009. Because of this, discussion of the nine month comparative operating statistics is unaffected, and the actual historical results of the successor and predecessor period are presented.

Our Products and Markets

Our two primary products are potash, and sulfate of potash magnesia or langbeinite which is marketed as Trio™ and may be referred to as such throughout this document. The majority of our revenues and gross margin are derived from the production and sales of potash. The percentage of our sales of Trio™ in recent quarters has increased relative to our total sales, as sales of Trio™ have been less impacted than potash sales in the current economic environment. The percentages of our net sales, which is defined below in the section titled Specific Factors Affecting our Results-Sales, and gross margins from potash were approximately as follows for the indicated periods.

Our potash is marketed for sale into three primary markets which are the agricultural market as a fertilizer, the industrial market as a component in drilling and fracturing fluids for oil and gas drilling, and the animal feed market as a nutrient. Our primary regional markets include agricultural areas and feed manufacturers west of the Mississippi River, as well as oil and gas exploration areas in the Rocky Mountains and the Permian Basin. We do, however, have domestic sales that go into the southeastern and eastern United States. Our potash production has a geographic concentration in the western United States and is therefore affected by weather and other conditions in this region. Demand for granular potash began to decline in the fall of 2008 due primarily to the interaction of potash prices being held at then historically high levels combined with the economic backdrop of falling prices for agricultural commodities. Variability in other input costs for the farm producer, as well as uncertainty resulting from the current U.S. and global financial market conditions, were also contributing factors. The relative decrease in demand has continued through the third quarter of 2009, as many farmers elected to apply granular potash at lower rates than historical application rates and hesitation continued by fertilizer dealers to hold inventory. The demand for our standard potash has also declined from historical levels, as there was a decrease in oil and gas drilling and completion of such wells due to lower oil and gas commodity prices, in conjunction with the fact that some drillers experimented with alternatives to standard potash or attempted to forego the use of potash altogether in drilling and completing their wells.

This downturn continues to negatively affect our sales volumes. Similar to the previous three quarters, our third quarter 2009 sales of potash were approximately half of our historical quarterly sales volumes. While we saw some strengthening in our September 2009 sales relative to previous months, we are continuing to see that the delay of the harvest throughout the United States, due to precipitation levels and the farmers' reduced ability to get into the fields, is also delaying fall applications of potash.

We believe that agricultural demand for fertilizers in the long-term will track population growth, meat consumption, and biofuel production, but demand may remain contracted during the current period of price and economic uncertainty. Our long-term view is based on data generated by Fertecon Limited, a fertilizer industry consultant, showing that over the past twenty-five years the domestic apparent consumption for potash has averaged approximately 9.3 million short tons with annual volatility of less than 10 percent through historical periods of low agricultural commodity prices, depressed oil and gas drilling, negative farmer margins, and a variety of other negative factors. While the 2008 / 2009 agricultural year consumption of potash was reduced by an estimated 40 percent, it remains to be seen what the 2009 / 2010 agricultural year application rates will be for potash. There is a continuing risk that potash application rates will be below historical levels. Over the longer term, we believe that domestic apparent consumption will eventually return to historical averages as the replacement of potassium in the soils is critical to continued high-yield agricultural production. We recognize, however, that farmers may continue to defer potash purchases as a reaction to the price of potash until their soil fertility suffers declines in potassium that are not acceptable to the farmers.

After the large North American producers lowered their list prices at the beginning of the third quarter of 2009, according to publicly-available data, we also reduced our list prices for potash in order to remain competitive. These price reductions, combined with the early fall fertilizer season, began to have a positive impact on the sales of our products by the end of the third quarter; however, due to continued overall pricing and demand uncertainty in the marketplace, further reductions in our sales prices may be necessary to remain competitive, as well as to bring sales volumes back to historical levels. Some current factors that may impact pricing and demand include when and at what price will China begin buying potash again on a larger scale, whether an unusually late harvest in the United States will negatively impact the fall fertilizer season, and whether future crop prices rise or fall. The settlement of contracts by large international potash producers in the third quarter of 2009 with India and Brazil resulted in adjustments in potash pricing in the world markets. According to Fertecon data,

after some purchases in the third quarter, Brazil has pulled back and may not purchase significant volumes for the remainder of the year. The international potash market is, however, still looking to a purchase contract from China for future price developments. We expect the eventual settlement of contracts with China to be another key price point in the broader international potash market which may clarify where potash prices settle in the near future.

It is unknown how soon sales of potash in the United States will increase or return to historical levels. It is possible that these lower prices for potash will not stimulate demand in the near future, as farm producers may continue to choose to limit their potash applications for a period of time and our customers may choose to keep their inventories low until potash prices further stabilize.

Industrial demand for our standard product will likely continue to correlate with oil and gas pricing and drilling and well completion activity, which has shown some signs of a mild recovery during the third quarter of 2009. Through industry publications, we monitor the oil and gas drilling rig count in the United States as an indicator of activity. In the event that demand for our standard potash product does not recover with industrial demand, we have the ability to convert some of the potash produced for the industrial market into product available for sale into the agricultural market by compacting our standard industrial potash into granular potash.

The feed component of our sales mix has increased on a relative basis, as we generally have not seen a downturn in that market. The recent decrease in the percentage of our sales attributable to the feed market was due to the mild improvement in overall sales levels in the third quarter of 2009. Overall, our feed sales have remained generally consistent from prior periods. The percentages of our potash sales volumes for all of our markets were approximately as follows for the indicated periods:

We are one of only two companies in the world that have economic reserves of langbeinite and produce sulfate of potash magnesia (Trio™). We began producing and marketing Trio™ in late 2005, and we are working to expand our production of this product to meet increasing demand, particularly for the granular-sized product. Trio™ is marketed into two primary markets, the agricultural market as a fertilizer and the animal feed market as a nutrient. We market Trio™ throughout the world through an exclusive marketing agreement with PCS Sales for sales outside North America. Increasing the market awareness of the benefits of Trio™ is a focus of our marketing efforts. Sales of Trio™ on an international basis tend to be larger bulk shipments and vary as to when such shipments take place; therefore, we see greater variability in our sales volumes from period to period when compared to our

domestic sales. The percentages of our Trio™ sales volumes shipped to destinations in the United States and exported were as follows for the indicated periods:

Global Factors Affecting our Results

Long-term global fertilizer demand has been driven primarily by population growth, changes in dietary habits, planted acreage, agricultural commodity yields and prices, grain inventories, application rates, global economic conditions, weather patterns and farm sector income. We expect these key variables to continue to have a significant impact on fertilizer demand for the foreseeable future. Sustained income growth and agricultural policies in the developing world also affect demand for fertilizer. Fertilizer demand is also affected by other geopolitical factors such as temporary disruptions in fertilizer trade related to government intervention and changes in the buying patterns of key consuming countries. In the near term, we note that the U.S. and world economic crisis has led to volatility in agricultural commodity prices, which may have an impact on the decisions farmers make related to their fertilization program. Our sales levels are well below those of a year ago, and prices have now fallen to levels that were last seen during the second and third quarters of 2008. Also, the wholesale prices of nitrogen and phosphate fertilizers, the two other primary crop nutrients, have declined relative to pricing in 2008 due primarily to a reduction in the cost of natural gas feedstocks required to produce those products and also due to supply dynamics in those industries. The combination of economic volatility and buyer hesitation has resulted in reduced demand for potash. Consequently, this has resulted in, and may continue to result in, our reduction of production levels of our products and the building of inventory in our warehouses.

Economically recoverable potash deposits are relatively rare and are well established. Virtually all potash is extracted from approximately twenty commercial deposits located in twelve countries. According to Fertecon Limited, the International Fertilizer Industry Association ("IFA"), and actual data published by potash mining companies, for all of 2008, six countries (Canada, Russia, Belarus, Germany, Israel and China) accounted for approximately 88 percent of the world's aggregate potash production. Companies in Canada and the former Soviet Union lead the global potash market due to the size and grade of their reserves, among other factors. As reported publicly, many of the larger potash producers have curtailed production in 2009 in an effort to more closely match global demand. Since much of the demand for potash from these producers comes from Brazil, India and China, the decrease in purchases by these countries has led to reported production declines by some of the world's largest potash producers. We believe that, when significant international demand does return, the Canadian, Russian, Belarusian, and German potash producers that curtailed production may recommence producing at higher rates at some of their idled plants.

Energy prices and consumption affect the potash industry in several ways. Energy policies in the United States have supported the development of biofuels, which currently rely upon agricultural products as feedstocks. As demand and prices for these feedstocks increase (or decrease), the use of fertilizer becomes more (or less) economically attractive. The economics of this industry are also impacted by input prices, and the relatively lower corn price through the summer of 2009 created demand for these inputs in the biofuel industry. In addition, energy prices affect the global levels of oil and gas drilling, and such drilling often consumes potash as a fluid additive as a means to reduce the risk of swelling clays in the formation. We believe that the positive benefit of potassium chloride in drilling and fracturing fluids has been well established in the oil and gas industry. According to drilling rig count data compiled by Baker Hughes, the number of rigs drilling for oil and gas in North America has increased slightly from its low point during the second quarter of 2009, resulting in a potential increase in demand for drilling fluids.

Changes in fuel prices directly impact the cost of transporting potash from producing to consuming regions. Changes in natural gas prices also impact the cost of processing potash. The average cost per MMBTU of natural gas for the nine months ended September 30, 2009, was lower than the average rate for the nine months ended September 30, 2008, contributing to a decrease in our energy costs. We estimate that every $1 per MMBTU change in the cost of natural gas changes our cost of potash by approximately $3 per short ton, in part dependent on our volume of production.

Specific Factors Affecting our Results

Our gross sales are derived from the sales of potash and Trio™ and are determined by the quantities of product we sell and the selling prices we realize. We quote prices to customers both on a delivered basis and on the basis of pick-up at our plants and warehouses. Freight costs are incurred only on a portion of our sales. Many of our customers arrange and pay for their own . . .
