NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — COMPANY BACKGROUND

We are the only producer of muriate of potash ("potassium chloride" or "potash") in the United States and are one of two producers of langbeinite ("sulfate of potash magnesia"), which we market and sell as Trio^®. We sell potash and Trio^® primarily into the agricultural market as a fertilizer. We also sell these products into the animal feed market as a nutritional supplement and sell potash into the industrial market as a component in drilling and fracturing fluids for oil and gas wells and other industrial inputs. We also sell water, primarily for industrial uses such as in the oil and gas industry. In addition, we sell by-products including salt, magnesium chloride, and brine, which are recorded as a credit to cost of goods sold. These by-product credits represented approximately 9% of total cost of goods sold for the six months ended June 30, 2018.

We produce potash from three solution mining facilities: our HB solar solution mine in Carlsbad, New Mexico, our solar solution mine in Moab, Utah, and our solar brine recovery mine in Wendover, Utah. We also operate the North compaction facility in Carlsbad, New Mexico, which compacts and granulates product from the HB mine. We produce Trio^® from our conventional underground East mine in Carlsbad, New Mexico.

"Intrepid," "our," "we," or "us," means Intrepid Potash, Inc. and its consolidated subsidiaries.

Note 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Financial Statement Presentation—Our unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation of interim financial information, have been included. These condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC on February 27, 2018.

Except for the accounting policies for revenue recognition that were updated as a result of adopting Accounting Standards Codification ("ASC") 606 "Revenue from Contracts with Customers" ("ASC Topic 606"), there have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2017.

Revenue Recognition—The majority of our revenue is derived from contract sales that are of a short-term nature. We account for revenue in accordance with ASC Topic 606, which we adopted on January 1, 2018, using the full retrospective method. Comparative information has been adjusted as if ASC Topic 606 was in effect during the comparative period. See Note 16 "Recently Adopted Accounting Pronouncements" for further discussion of the adoptions, including the retrospective adjustment made to our 2017 financial information.

Performance Obligations: A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606. The contract's transaction price is allocated to the performance obligations and recognized as revenue when the performance obligations are satisfied. Generally, our performance obligations are satisfied when we ship product from our facility to the customer. Shipping and handling charges are accounted for as a fulfillment cost and, as such, are not considered to be a separate performance obligation. Revenue from sales to customers at a single point in time accounted for all our revenue for the three and six months ended June 30, 2018, and 2017.

Contract Estimates: In certain circumstances, we may sell product to customers where the sales price is variable. For such sales, we estimate the sales price we expect to realize based on the facts and circumstances for each sale, including historical experience, and recognize revenue to the extent it is probable that a subsequent change in estimate will not result in a significant revenue reversal compared to the cumulative revenue recognized under the contract.

5

Contract Balances: The timing of revenue recognition, billings and cash collection may result in contract assets or contract liabilities. For certain contracts, the customer has agreed to pay us before we have satisfied our performance obligations. Customer payments received before we have satisfied our performance obligations are accounted for as a contract liability. As of June 30, 2018, we had $7.3 million in contract liabilities which are included in "Other current liabilities" on the condensed consolidated balance sheets. We had no contract liabilities at December 31, 2017. For the three and six months ended June 30, 2018, we recognized $0.5 million of revenue as the performance obligation was satisfied.

Disaggregation of Revenue: In the following table, revenue is disaggregated by our primary products.

	Three Months Ended June 30,
	2018		2017
Product (amounts in thousands)	Revenue		Revenue		Timing of revenue recognition

Reclassifications of Prior Period Presentation—Certain prior period amounts have been reclassified in order to conform to the current period presentation. These reclassifications had no effect on the reported results of operations.

Note 3 — EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period. For purposes of determining diluted earnings per share, basic weighted-average common shares outstanding are adjusted to include potentially dilutive securities, including restricted stock, stock options, and performance units. The treasury-stock method is used to measure the dilutive impact of potentially dilutive shares. Potentially dilutive shares are excluded from the diluted weighted-average shares outstanding computation in periods in which they have an anti-dilutive effect. The following table shows the calculation of basic and diluted earnings (loss) per share (in thousands, except per share amounts):

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018		2017
Net (loss) income	$	(958	)	$	(5,935	)	$	799	$	(19,613	)

Diluted	$	(0.01	)	$	(0.05	)	$	0.01	$	(0.19	)

The following table shows the shares that have an anti-dilutive effect and are excluded from the diluted weighted-average shares outstanding computations:

	Three Months Ended June 30,		Six Months Ended June 30,
	2018	2017	2018	2017
Anti-dilutive effect of restricted stock	3,221	2,640	—	2,794
Anti-dilutive effect of stock options outstanding	3,587	1,899	1,154	1,883
Anti-dilutive effect of performance units	—	63	—	63

Note 4— CASH, CASH EQUIVALENTS AND RESTRICTED CASH

Total cash, cash equivalents and restricted cash, as shown on the Condensed Consolidated Statements of Cash Flows are included in the following accounts at June 30, 2018 and 2017:

	June 30, 2018		June 30, 2017
Cash and cash equivalents	$	26,234	$	6,190
Restricted cash included in other long-term assets	481		481
Total cash, cash equivalents, and restricted cash shown in the statement of cash flows	$	26,715	$	6,671

Restricted cash included in other long-term assets on the balance sheet represents amounts whose use is restricted by contractual agreements with the Bureau of Land Management and the State of Utah as security to fund future reclamation obligations at our sites.

Note 5— INVENTORY AND LONG-TERM PARTS INVENTORY

The following summarizes our inventory, recorded at the lower of weighted-average cost or estimated net realizable value, as of June 30, 2018, and December 31, 2017 (in thousands):

	June 30, 2018		December 31, 2017

Parts inventories are shown net of any required allowances. At June 30, 2018, and December 31, 2017, allowances for parts inventory obsolescence were $3.4 million and $4.2 million, respectively.

As a result of routine assessments of the lower of weighted-average cost or estimated net realizable value of our finished goods product inventory, for the three months ended June 30, 2018, and 2017, we recorded $0.1 million and $0.3 million, respectively.

Note 7 — DEBT

Senior Notes—As of June 30, 2018, we had outstanding $60 million of senior notes (the "Notes") consisting of the following series:

• $24 million of Senior Notes, Series A, due April 16, 2020

• $18 million of Senior Notes, Series B, due April 14, 2023

• $18 million of Senior Notes, Series C, due April 16, 2025

We are required to prepay $10 million in principal of the Notes, plus accrued interest and a make-whole amount, on or before December 31, 2018.

The agreement governing the Notes contains certain financial covenants, including the following:

• For the quarters ended June 30, 2018, and ending September 30, 2018, we were and are required to maintain a minimum fixed charge coverage amount of negative $15 million and negative $10 million, respectively. Thereafter, we are required to maintain a minimum fixed charge coverage ratio that starts at 0.25 to 1.0 for the quarter ending December 31, 2018, and increases to 1.3 to 1.0 for each quarter ending on or after September 30, 2019. As of June 30, 2018, we were in compliance with these financial covenants as our fixed charge coverage amount was $21.9 million, and our fixed charge coverage ratio was 8.6 to 1.0.

• We are required to maintain a maximum leverage ratio that started at 11.5 to 1.0 for the quarter ended June 30, 2018, and decreases each quarter until it reaches 3.5 to 1.0 for each quarter ending on or after September 30, 2019. As of June 30, 2018, our leverage ratio was 1.5 to 1.0.

Fixed charge coverage amount, fixed charge coverage ratio, and leverage ratio are calculated in accordance with the agreement governing the Notes.

For the three and six months ended June 30, 2018, the interest rates on the Notes were 3.73% for the Series A Notes, 4.63% for the Series B Notes and 4.78% for the Series C Notes. These rates represent the lowest interest rates available under the Notes. The interest rates may adjust upward if we do not continue to meet certain financial covenants.

We have granted to the collateral agent for the noteholders a first lien on substantially all of our non-current assets and a second lien on substantially all of our current assets. We are required to offer to prepay the Notes with the proceeds of dispositions of certain specified property and with the proceeds of certain equity issuances, as set forth in the agreement. The obligations under the Notes are unconditionally guaranteed by several of our subsidiaries.

We were in compliance with the applicable covenants under the agreement governing the Notes as of June 30, 2018.

Our outstanding long-term debt, net, as of June 30, 2018, and December 31, 2017, is as follows (in thousands):

Credit Facility—We maintain an asset-based revolving credit facility with Bank of Montreal that matures on October 31, 2019. The credit facility allows us to borrow up to $35 million subject to monthly limits based on our inventory and receivables. We can use up to $10 million of borrowings under the agreement to make payments on the Notes.

Borrowings on the credit facility bear interest at 1.75% to 2.25% above LIBOR (London Interbank Offered Rate), based on average availability under the credit facility. We have granted to Bank of Montreal a first lien on substantially all of our current assets and a second lien on substantially all of our non-current assets.

We regularly borrow and repay amounts under the facility for near-term working capital needs and may do so in the future. For the three months ended June 30, 2018, we had no borrowings and repaid $1.5 million under the facility. For the six months ended June 30, 2018, we borrowed $13.5 million and repaid $17.4 million under the facility. As of June 30, 2018, we had no borrowings outstanding and $3.8 million in outstanding letters of credit under the facility. Considering the outstanding letters of credit, we have $25.7 million available under the facility as of June 30, 2018. We were in compliance with the applicable covenants under the facility as of June 30, 2018.

Interest expense is recorded net of any capitalized interest associated with investments in capital projects. We incurred gross interest expense of $0.9 million and $4.3 million for the three months ended June 30, 2018, and 2017, respectively. For the six months ended June 30, 2018 and 2017, we incurred gross interest expense of $1.8 million and $8.7 million, respectively.

Amounts included in interest expense for the three and six months ended June 30, 2018, and 2017, are as follows (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017

Note 8 — FINANCIAL INFORMATION FOR SUBSIDIARY GUARANTORS OF POSSIBLE FUTURE

PUBLIC DEBT

Intrepid Potash, Inc., as the parent company, has no independent assets or operations, and operations are conducted solely through its subsidiaries. Cash generated from operations is held at the parent-company level as cash on hand and totaled $26.2 million and $1.1 million at June 30, 2018, and December 31, 2017, respectively. If one or more of our wholly-owned operating subsidiaries guarantee public debt securities in the future, those guarantees will be full and unconditional and will constitute the joint and several obligations of the subsidiary guarantors. Our other subsidiaries are minor. There are no restrictions on our ability to obtain cash dividends or other distributions of funds from the subsidiary guarantors, except those imposed by applicable law.

Note 9 — ASSET RETIREMENT OBLIGATION

We recognize an estimated liability for future costs associated with the abandonment and reclamation of our mining properties. A liability for the fair value of an asset retirement obligation and a corresponding increase to the carrying value of the related long-lived asset are recorded as the mining operations occur or the assets are acquired.

Our asset retirement obligation is based on the estimated cost to abandon and reclaim the mining operations, the economic life of the properties, and federal and state regulatory requirements. The liability is discounted using credit adjusted risk-free rate estimates at the time the liability is incurred or when there are upward revisions to estimated costs. The credit adjusted risk-free rates used to discount our abandonment liabilities range from 6.9% to 9.7%. Revisions to the liability occur due to construction of new or expanded facilities, changes in estimated abandonment costs or economic lives, or if federal or state regulators enact new requirements regarding the abandonment or reclamation of mines.

10

Following is a table of the changes to our asset retirement obligation for the following periods (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Asset retirement obligation, at beginning of period	$	21,893	$	20,365	$	21,476	$	19,976
Accretion of discount	417		389		834		778
Total asset retirement obligation, at end of period	$	22,310	$	20,754	$	22,310	$	20,754

The undiscounted amount of asset retirement obligation was $59.5 million as of June 30, 2018.

Note 10 — COMMON STOCK

In May 2017, we established an at-the-market offering program, which gives us the capacity to issue up to $40 million of our common stock. We sold no shares under the at-the-market offering program during the first six months of 2018. We have remaining capacity to issue and sell up to $37.8 million of additional shares of common stock under the program.

Note 11 — COMPENSATION PLANS

Equity Incentive Compensation Plan—Our Board of Directors and stockholders adopted a long-term incentive compensation plan called the Intrepid Potash, Inc. Amended and Restated Equity Incentive Plan (the "Plan"). We have issued common stock, restricted stock, performance units, and non-qualified stock option awards under the Plan. At June 30, 2018, there were approximately 2.3 million shares available for issuance under the Plan.

For the three months ended June 30, 2018, we granted to members of our Board of Directors 0.1 million shares of restricted stock, which vest one year from the date of the grant.

For the six months ended June 30, 2018, we granted 0.5 million shares of restricted stock and 1.6 million non-qualified stock options to members of our Board of Directors, executive officers, and other key employees. These awards vest one to three years from the date of the grant, and in some cases, contain performance-vesting conditions or market conditions.

As of June 30, 2018, the following awards were outstanding under the Plan:

	Outstanding as of June 30, 2018
Restricted Stock	2,903,388
Non-qualified Stock Options	3,574,198

Total share-based compensation expense was $1.3 million and $0.7 million for the three months ended June 30, 2018, and 2017, respectively. For the six months ended June 30, 2018, and 2017, total share-based compensation expense was $2.3 million and $1.7 million, respectively. As of June 30, 2018, we had $8.1 million of total remaining unrecognized compensation expense related to awards, that will be expensed through 2021.

Note 12 — INCOME TAXES

Our anticipated annual tax rate is impacted primarily by the amount of taxable income associated with each jurisdiction in which our income is subject to income tax, permanent differences between the financial statement carrying amounts and tax bases of assets and liabilities.

During both the three and six months ended June 30, 2018, and June 30, 2017, we incurred an immaterial amount of income tax expense. Our effective tax rate was 0% for both the three and six months ended June 30, 2018, and 2017, which differed from the statutory rate primarily due to the valuation allowance established to offset our deferred tax assets.

11

As of June 30, 2018, we do not believe it is more likely than not that we will fully realize the benefit of our deferred tax assets. As such, we maintained a full valuation allowance against our net deferred tax assets as of June 30, 2018, and December 31, 2017.

Note 13 — COMMITMENTS AND CONTINGENCIES

Reclamation Deposits and Surety Bonds—As of June 30, 2018, and December 31, 2017, we had $18.8 million of security placed principally with the State of Utah and the Bureau of Land Management for eventual reclamation of our various facilities. Of this total requirement, as of June 30, 2018, and December 31, 2017, $0.5 million consisted of long-term restricted cash deposits reflected in "Other assets, net" on the condensed consolidated balance sheets and $18.3 million was secured by surety bonds issued by an insurer. The surety bonds are held in place by an annual fee paid to the issuer.

We may be required to post additional security to fund future reclamation obligations as reclamation plans are updated or as governmental entities change requirements.

Legal—In February 2015, Mosaic Potash Carlsbad Inc. (“Mosaic”) filed a complaint and application for preliminary injunction and permanent injunction against Steve Gamble and us in the Fifth Judicial District Court for the County of Eddy in the State of New Mexico. In August 2015, the court denied Mosaic’s application for preliminary injunction. In July 2016, Mosaic filed a second complaint against Mr. Gamble and us in US District Court for the District of New Mexico. In January 2018, the two lawsuits were consolidated into one lawsuit pending in the US District Court for the District of New Mexico.  Mr. Gamble is a former employee of Intrepid and Mosaic. Mosaic alleges against us violations of the New Mexico Uniform Trade Secrets Act, tortious interference with contract relating to Mr. Gamble’s separation of employment from Mosaic, violations of the Computer Fraud and Abuse Act, conversion, and civil conspiracy relating to the alleged misappropriation of Mosaic’s confidential information and related actions.  Mosaic seeks monetary relief of an unspecified amount, including damages for actual loss and unjust enrichment, exemplary damages, attorneys’ fees, and injunctive relief and has alleged that it has spent hundreds of millions of dollars to research and develop its alleged trade secrets.  The lawsuit is progressing through discovery.  We are vigorously defending against the lawsuit. Because this matter is at an early stage, we are unable to reasonably estimate the potential amount of loss, if any.

We are also subject to other claims and legal actions in the ordinary course of business. Legal costs are expensed as incurred. While there are uncertainties in predicting the outcome of any claim or legal action, we believe that the ultimate resolution of these other claims or actions is not reasonably likely to have a material adverse effect on our financial condition, results of operations, or cash flows.

Other—In May 2018, one of our water customers claimed that its water-metering equipment was not working properly in March 2018 and April 2018, thereby resulting in the customer overreporting its water use by approximately $1.7 million. We are working with the customer to determine the correct amount of water used. Although we have not completed this process, we believe it is probable that the customer overreported its water use and have estimated the overreported amount to range between $0.6 million to $1.7 million. As such, we recorded $0.6 million of operating expense in the second quarter of 2018, for a contingent liability relating to this matter.

Future Operating Lease Commitments—We have operating leases for land, mining and other operating equipment, offices, and railcars, with original terms ranging up to 30 years.

Rental and lease expenses for the three months ended June 30, 2018, and 2017, were $1.0 million and $1.5 million, respectively. Rental and lease expenses for the six months ended June 30, 2018, and 2017, were $2 million and $3 million, respectively.

12

Note 14 — FAIR VALUE

We measure our financial assets and liabilities in accordance with Accounting Standards Codification™ ("ASC") Topic 820, Fair Value Measurements and Disclosures.

As of June 30, 2018, and December 31, 2017, our cash consisted of bank deposits. Other financial assets and liabilities including accounts receivable, refundable income taxes, accounts payable, accrued liabilities, and advances on credit facility are carried at cost which approximates fair value because of the short-term nature of these instruments.

As of June 30, 2018, and December 31, 2017, the estimated fair value of our outstanding Notes was $55.9 million and $58.8 million, respectively. The fair value of our Notes is estimated using a discounted cash flow analysis based on current borrowing rates for debt with similar remaining maturities and ratings (a Level 2 input) and is designed to approximate the amount at which the instruments could be exchanged in an arm's-length transaction between knowledgeable willing parties.

Note 15 — BUSINESS SEGMENTS

We have two business segments: potash and Trio^®. Our reportable segments are determined by management based on a number of factors including the types of potassium-based fertilizer produced, production processes, markets served and the financial information available to our chief operating decision maker. We evaluate performance based on the gross margins of the respective business segments and do not allocate corporate selling and administrative expenses, among others, to the respective segments. Total assets are not presented for each reportable segment as they are not reviewed by, nor otherwise regularly provided to, the chief operating decision maker. All sales are to external customers. Water sales and corporate expenses are included in "Other."

Information for each segment is provided in the following tables (in thousands):

Note 16 — RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, as amended by ASU No. 2016-12, "Revenue from Contracts with Customers (Topic 606)," which requires revenue to be recognized based on the amount

14

an entity is expected to be entitled to for promised goods or services provided to customers. The standard also requires expanded disclosures regarding contracts with customers. This standard became effective for us beginning January 1, 2018.

Our revenue predominantly continues to be recognized when products are shipped from our manufacturing facilities. Under the new revenue standard, certain sales where revenue was previously deferred, such as sales in which the final price was not fixed and determinable, we now recognize revenue when the product is shipped using the sales price we expect to realize. In conjunction with our adoption of Topic 606 on January 1, 2018, primarily related to variable pricing contracts, we recorded a net increase to opening retained deficit of $0.5 million.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230)" which is intended to clarify and align how certain cash receipts and cash payments are presented and classified in the statement of cash flows where there is currently diversity in practice. ASU No. 2016-15 specifically addresses eight classification issues within the statement of cash flows including debt prepayments or debt extinguishment costs; proceeds from the settlement of insurance claims; and separately identifiable cash flows and application of the predominance principle. This standard became effective for us beginning January 1, 2018. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.

    In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740)" which became effective for us beginning January 1, 2018. This standard requires us to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" which became effective for us beginning January 1, 2018. This standard requires us to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows and will no longer require transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. As a result of including restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts presented on the condensed consolidated statement of cash flows, net cash flows for the six months ended June 30, 2017, decreased by $3.5 million.

Pronouncements Issued But Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires, among other things, lessees to recognize lease assets and liabilities on their balance sheets for those leases classified as operating leases under previous generally accepted accounting principles. These assets and liabilities must be recorded generally at the present value of the contracted lease payments, and the cost of the lease must be allocated over the lease term on a straight-line basis. This guidance is effective for us for annual and interim periods in fiscal years beginning after December 15, 2018, with a modified retrospective transition method mandated.

We are continuing to work on ensuring we have identified all potential leases. We estimate additional assets and liabilities recorded after adoption of ASU No. 2016-02, "Leases (Topic 842)" will be less than $10 million.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - (Topic 326): Measurement of Credit Losses on Financial Instruments," which changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. This guidance is effective for us for annual and interim periods in fiscal years beginning after December 15, 2018. Because we have historically experienced minimal bad debt expense related to our trade receivables, we do not believe the adoption of this new standard will have a material impact on our condensed consolidated financial statements.

• challenges to our water rights;

• our ability to comply with the terms of our senior notes and revolving credit facility, including the underlying covenants, to avoid a default under those agreements;

• our ability to expand Trio^® sales internationally and manage risks associated with international sales, including pricing pressure and freight costs;

• our ability to successfully identify and consummate profitable growth opportunities;

• the costs of, and our ability to successfully execute, any strategic projects;

• declines or changes in agricultural production or fertilizer application rates;

• declines in the use of potassium-related products or water by oil and gas companies in their drilling operations;

• further write-downs of the carrying value of assets, including inventories;

• circumstances that disrupt or limit production, including operational difficulties or variances, geological or geotechnical variances, equipment failures, environmental hazards, and other unexpected events or problems;

• changes in reserve estimates;

• currency fluctuations;

• adverse changes in economic conditions or credit markets;

• the impact of governmental regulations, including environmental and mining regulations, the enforcement of those regulations, and governmental policy changes;

• the other risks, uncertainties, and assumptions described in Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2017, as updated by this report.

In addition, new risks emerge from time to time. It is not possible for our management to predict all risks that may cause actual results to differ materially from those contained in any forward-looking statements we may make.

16

In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in these forward-looking statements. As a result, you should not place undue reliance on these forward-looking statements. We undertake no duty to update or revise publicly any forward-looking statements to conform those statements to actual results or to reflect new information or future events.

Throughout this report, we refer to average net realized sales price per ton, which is a non-GAAP measure that we calculate as sales less freight costs then divided by sales tons. More information about this measure, including a reconciliation of this measure to the most directly comparable GAAP measure, is below under the heading "Non-GAAP Financial Measure."

Company Overview

We are the only producer of potash in the United States and are one of two producers of langbeinite, which we market and sell as Trio^®. We sell potash and Trio^® primarily into the agricultural market as a fertilizer. We also sell these products into the animal feed market as a nutritional supplement and sell potash into the industrial market as a component in drilling and fracturing fluids for oil and gas wells and other industrial inputs. We also sell water, primarily for industrial uses such as in the oil and gas industry. In addition, we sell by-products including salt, magnesium chloride, and brine, which are recorded as a credit to cost of goods sold. These by-product credits represented approximately 9% of total cost of goods sold for the six months ended June 30, 2018.

We produce potash from three solution mining facilities: our HB solar solution mine in Carlsbad, New Mexico, our solar solution mine in Moab, Utah, and our solar brine recovery mine in Wendover, Utah. We also operate the North compaction facility in Carlsbad, New Mexico, which compacts and granulates product from the HB mine. We produce Trio^® from our conventional underground East mine in Carlsbad, New Mexico.

We have additional opportunities to develop mineralized deposits of potash in New Mexico, as well as to continue the optimization of our processing plants. These opportunities include additional solution mining activities, additional recoveries of langbeinite, development of by-product and water markets, and acceleration of production from our reserves.

We routinely post important information about us and our business, including information about upcoming investor presentations, on our website under the Investor Relations tab. We encourage investors and other interested parties to enroll on our website to receive automatic email alerts or Really Simple Syndication (RSS) feeds regarding new postings. Our website is intrepidpotash.com.

Significant Business Trends and Activities

Our financial results have been, or are expected to be, impacted by several significant trends and activities, which are described below. We expect that these trends will continue to impact our results of operations, cash flows, and financial position.

• Trio^® pricing and demand. Sales volume increased 8% in the first half of 2018, compared to the same period in 2017, driven by a 27% increase in domestic sales volume. We saw some customers return to applying Trio^® on non-specialty crops due to favorable pricing against the component nutrients. Our international sales volume declined by 32% during the first half of 2018 compared to the first half of 2017 as we focused on a price-over-volume strategy. Domestic sales comprised 80% of the total Trio^® sales volume for the first half of 2018, compared to 68% in the first half of 2017. At current price levels, we expect domestic Trio^® sales to continue to represent a majority of Trio^® sales volume.

During the first half of 2018, Trio^® average net realized sales price per ton decreased 4% as compared to the first half of 2017. Domestically, we have seen higher market prices. However, unfavorable and increased freight rates have continued to negatively impact our average net realized sales price per ton. We expect the domestic Trio^® average net realized sales price per ton to increase slightly during the fourth quarter of 2018, due to additional domestic price increases that were announced during the quarter.

We experience seasonality in domestic Trio^® demand, with more purchases coming in the first and second quarters. In turn, we generally have increased inventory levels in the third and fourth quarters in anticipation of expected demand for the following year. We continue to operate our facilities at production levels that approximate expected demand and allow us to manage inventory levels.

• Potash pricing and demand. For the six months ended June 30, 2018, our potash average net realized sales price per ton increased 5% compared to the same period in 2017 due to strong demand in the agricultural market. Our average net realized sales price per ton for potash in the second quarter of 2018 was $254 per ton, which is the highest we have realized since the fourth quarter of 2015. With price increases announced in June, we expect potash pricing to remain strong for the remainder of 2018.

During the first half of 2018, we sold a higher percentage of total potash tons into the agricultural market as compared to the first half of 2017. Sales into the industrial market decreased, and sales into the animal feed market remained steady. We expect that the majority of our potash sales will continue to be made into the agricultural market.

Although production curtailments from us and other producers over the past several years reduced potash supply in North America, global effective capacity continues to exceed demand. Potash prices are a significant driver of profitability for our business. Pricing of our potash is influenced principally by the price established by our competitors. The interaction of global potash supply and demand, ocean, land, and barge freight rates, and currency fluctuations also influence pricing.

18

The specific timing of when farmers apply potash remains highly weather dependent and varies across the numerous growing regions within the U.S. The timing of potash sales is significantly influenced by the marketing programs of potash producers, as well as storage volumes closer to the farm gate. We also experience seasonality in potash demand, similar to domestic Trio^®. The combination of these items results in variability in potash sales and shipments, thereby increasing volatility of sales volumes from quarter to quarter and season to season.

• Water and by-product sales. We continue to diversify our sources of income by expanding sales of water and by-products, particularly to service the oil and gas markets near our operating plants. In the first half of 2018, water sales increased to $8.7 million compared to $1.4 million during the first half of 2017. In addition, we sold $1.3 million of water that was accounted for as by-product credits to our cost of goods sold during the first half of 2018.

We have put in place a diverse set of arrangements aimed at generating a long-term recurring revenue stream from water sales. This includes a pre-arranged water commitment of $15 million per year for five years that began in 2018. We are modifying our water guidance calculation and language to focus on cash and expect to receive $25 million to $35 million in cash related to water in 2018. This amount includes $15 million in cash that we expect to receive under the water commitment described above, but that is accounted for as deferred revenue until the underlying water is delivered. In the first half of 2018, we received $13.4 million of cash for water and at June 30, 2018, we had $5.4 million in accounts receivable related to water. We continue to incur minimal expenditures associated with this revenue stream.

Water rights in New Mexico are subject to a stated purpose and place of use, and our water rights were originally issued for uses relating to our mining operations. To sell water under these rights for oil and gas development, we like all other parties must apply for a permit from the New Mexico Office of the State Engineer ("OSE") to change the purpose and/or place of use of the underlying water rights. The OSE reviews and makes a determination as to the validity of the right and if it determines the requested change will not negatively impact other valid interests, the OSE can issue a preliminary authorization for the change. The preliminary authorization allows for water sales to begin immediately, subject to repayment if the underlying water rights were ultimately found to be invalid. Third parties may protest the preliminary authorization at minimal cost and frequently do so. Once protested, the OSE is required to hold a hearing to determine if the preliminary authorization was appropriate. Virtually all of our water sales are being made under preliminary authorizations issued by the OSE. Third parties have protested these preliminary authorizations, and we expect the OSE to hold a hearing on the protests in late 2018 or early 2019. In the meantime, we are working with OSE and the protesting parties to resolve the protested issues, including the validity of the protested water rights, through mediation. We continue to operate under the preliminary authorizations until the hearing process is complete. We may face political and regulatory issues relating to the potential use of the maximum amount of our rights. However, we believe that our legal position with respect to the validity of our water rights is solid and that we will be able to meet our water commitments.

We also produce salt, magnesium chloride and brines as by-products of our potash and Trio^® operations. Our salt is used in a variety of markets. Magnesium chloride is typically used as a road-treatment agent. Our brines are used primarily by the oil and gas industry to support well development and completion activities.

• Growth strategy. We continue to implement or consider initiatives designed to maximize the value of our existing assets, such as through increased potash and Trio^® production, and increased sales of water, magnesium chloride, salt, and brine. We are also exploring ways to potentially monetize the known but small lithium resource in our Wendover ponds. In addition, we may enter into new or complementary businesses that expand our product offerings beyond our existing assets, through the acquisition of companies or assets or otherwise. These efforts are at a very early exploratory stage and may not come to fruition.

Consolidated Results for the Three- and Six-Months Periods Ended June 30, 2018, and 2017

Total sales in the three months ended June 30, 2018, increased 13% compared to the three months ended June 30, 2017, due to increased water and Trio^® sales. Water sales have continued to ramp up since we entered the water business in 2017. Increased Trio^® sales were driven by an increase in demand from domestic customers.

Our total cost of goods sold increased 8% for the three months ended June 30, 2018, as compared to the three months ended June 30, 2017, primarily due to the increase in Trio^® tons sold. We generated a higher gross margin for the second quarter of 2018, compared to the second quarter of 2017, driven by the increase of $2.9 million in water sales and the increase in sales of by-products.

For the six months ended June 30, 2018, total sales increased $10.5 million or 11% compared to the same period in 2017, due to an increase in water sales of $7.3 million and an increase in Trio^® sales of $2.9 million. As mentioned, several water agreements were entered into throughout 2017, and purchase activity under those agreements began to ramp up during the latter half of 2017, and has continued into 2018. Increased Trio^® sales resulted from the increase in demand from domestic customers as we saw customers return to applying Trio^® on non-specialty crops again due its favorable pricing against the component nutrients.

Our total cost of goods sold for the six months ended June 30, 2018, decreased slightly from the same period in 2017, mainly due to the increase in by-product sales, which are accounted for as a credit to cost of goods sold.

Selling and Administrative Expense

Selling and administrative expenses increased $1.5 million, or 33%, to $6.2 million for the three months ended June 30, 2018, as compared to the prior-year period. Selling and administrative expenses increased $1.1 million, or 12% for the first half of 2018, compared to the first half of 2017. The increase in both periods was due to our reestablishing our employee

20

cash bonus program for 2018 and granting annual equity awards to employees in March 2018, instead of June 2017, for the previous year.

Care and Maintenance Expenses

Mining operations at our West facility in Carlsbad, New Mexico, were temporarily idled in mid-2016. For the three months ended June 30, 2018, and 2017, we incurred care and maintenance expenses related to our West facility of $0.1 million, and $0.4 million, respectively. Expenses were higher in 2017 as we incurred initial costs to transition the plant to its current state of care and maintenance.

For the first half of 2018, we incurred care and maintenance expenses of $0.2 million compared to $1.1 million for the same period in 2017. As mentioned, expenses were higher in 2017 as we incurred initial costs to transition our West facility to its current state of care and maintenance. We expect care and maintenance expenses going forward to approximate the 2018 level.

Other Operating Expenses

Other operating expense increased $0.1 million from $0.6 million for the three months ended June 30, 2017 to $0.7 million for the three months ended June 30, 2018. In May 2018, one of our water customers claimed that its water-metering equipment was not working properly in March and April 2018, thereby resulting in the customer overreporting its water use by approximately $1.7 million due to the meter issue. We are working with the customer to determine the correct amount of water used. Although we have not completed this process, we believe it is probable that the customer overreported it water use and have estimated the overreported amount to range between $0.6 million to $1.7 million. As such, we recorded $0.6 million of operating expense in the second quarter of 2018, for a contingent liability relating to this matter. In 2017, we recorded $0.6 million of operating expense in the second quarter of 2017 for a one-time accrual to resolve land impact issues on or adjacent to our property in New Mexico. This issue was resolved and paid in early 2018.

For the six months ended June 30, 2018, other operating expenses decreased to $0.9 million from $2.3 million for the six months ended June 30, 2017. In 2017, we incurred a loss of $1.6 million on the sale of an asset and recorded $0.6 million of operating expense for a one-time accrual to resolve land impact issues on or adjacent to our property in New Mexico. In 2018, we recorded $0.6 million of operating expense for the water-reporting issue discussed above.

Interest Expense

For the three months ended June 30, 2018, interest expense decreased by $3.3 million compared to the same period in 2017, as our average debt balance decreased from $89 million during the second quarter 2017, to $60 million during the second quarter of 2018. In addition, the interest rate incurred during the second quarter of 2018 was 400 basis points less than the interest rate incurred in the second quarter of 2017, due to our improved financial condition. Additionally, we incurred make-whole payments of $1.8 million related to $23 million of principal repayments made in the second quarter of 2017, and we wrote off deferred financing costs of $0.2 million associated with those principal repayments.

Interest expense for the first half of 2018, decreased to $1.8 million from $8.7 million during the same period in 2017, as our average debt balance outstanding decreased to $60 million in the first half of 2018, from $109 million during the first half of 2017. Our interest incurred during the first half of 2018 was 400 basis points lower than the same period in 2017, due to our improved financial condition. Finally, during the first half of 2017, we incurred make-whole payments of $2.6 million and wrote off $0.8 million of deferred financing fees related to principal prepayments of $69 million made during the first half of 2017.

Interest expense is recorded net of any capitalized interest associated with investments in capital projects. Amounts included in interest expense for the three and six months ended June 30, 2018, and 2017, are as follows (in thousands):

Three Months Ended June 30, 2018, and 2017

Our potash sales revenue increased slightly in the second quarter of 2018, compared to the same period in 2017, due to an 8% increase in our average net realized sales price per ton. This increase was partially offset by a 5% decrease in potash sales volume. This decrease was due to normal variation in the timing of sales to agricultural and feed customers and a decrease in sales volume to industrial customers in the second quarter of 2018, compared to the same period in 2017.

Our potash cost of goods sold decreased 9% in the second quarter of 2018, compared to the same period in 2017, due mainly to a 5% decrease in sales volume and an increase in by-product sales, which are accounted for as a credit to cost of goods sold.

Potash freight expense decreased 8% in the second quarter of 2018, compared to the second quarter of 2017, due mainly to a 5% decrease in the volume of potash sold. While freight rates have increased as carriers are operating at full capacity, our freight expense is also impacted by the proportion of customers arranging for and paying their own freight costs, and the geographic distribution of our potash sales.

Six Months Ended June 30, 2018, and 2017

Our potash sales volume in the first half of 2018, was 4% less than the same period in 2017, due to a decrease in sales in the industrial markets. Our decreased sales volume was partially offset by a 5% increase in our average net realized sales price per ton. The increase in sales price was driven by overall increases in the prevailing market price for potash.

Our potash cost of goods sold decreased 12% due to a 4% decrease in sales volume, and an increase in by-product sales, which are accounted for as a credit to cost of goods sold.

Our freight costs increased 3% for the six months ended June 20, 2018, compared to the same period in 2017. Freight rates have increased in 2018, as freight carriers have been operating near full capacity. Our freight costs are impacted by the proportion of customers paying for their own freight, the geographic distribution of our products and the freight rates of our carriers.

Warehouse and handling costs decreased 11% in the first half of 2018 compared to 2017, due to reduced rental costs in 2018 compared to 2017.

Three Months Ended June 30, 2018, and 2017

Trio^® sales increased 17% for the three months ended June 30, 2018, as compared to the same period in 2017, due to a 17% increase in sales volume. During the second quarter of 2018, we saw increased demand from domestic Trio^® as some customers return to applying Trio^® on non-specialty crops due to favorable pricing against the component nutrients. Average net realized sales price per ton for the second quarter of 2018, decreased 4% compared to the second quarter of 2017, due to a 28% increase in freight expense. Freight expense increased due to higher sales volume and increased freight rates, which have continued to increase as carriers have been operating at full capacity.

Cost of goods sold for Trio^® increased 30% in the second quarter of 2018, compared to the second quarter of 2017, due mainly to increased sales volumes and reduced Trio^® production. Our Trio^® production volume decreased by 21% in the second quarter of 2018, compared to the second quarter of 2017, as a result of our decision to reduce production in an effort to match expected demand and to manage inventory levels. As a majority of our production costs are fixed, decreases in tons produced increases our per ton production costs.

23

Six Months Ended June 30, 2018, and 2017

Trio^® sales increased by 8% for the first half of 2018, as compared to the same period in 2017, due to an 8% increase in sales volume. As mentioned, we saw increased demand from domestic Trio^® as some customers return to applying Trio^® on non-specialty crops due to favorable pricing against the component nutrients. Average net realized sales price per ton decreased by 4% in the first half of 2018, compared to the same period in 2017, due to a 17% increase in freight costs. Freight expense increased due to increased sales volume and increased freight rates. Domestically, during the fourth quarter of 2018, we expect to benefit from price increases announced in early June of 2018.

Our freight costs increased by 17% in the first half of 2018, compared to the same period in 2017, due to an 8% increase in sales volume, coupled with an increase in freight rates. As mentioned, freight rates have been increasing as carriers are operating near full capacity.

Cost of goods sold for Trio^® increased during the first half of 2018, compared to the same period in 2017, due to an 8% increase in tons sold and a decrease in tons produced. Because most of our production costs are fixed, a decrease in tons produced has an inverse effect on production costs per ton. Our production volume decreased in the first half of 2018, compared to the first half of 2017, as a result of our decision to reduce Trio^® production in mid-2017, in an effort to match expected demand.

Additional Information Relating to Trio^® 

The percentage of Trio^® tons sold into the export market decreased during the three and six months ended June 30, 2018, compared to the same periods in 2017, as we have been more selective in pursuing sales with the highest average net realized sales price per ton.

	United States	Export
For the three months ended June 30, 2018	84%	16%
For the six months ended June 30, 2018	80%	20%
For the three months ended June 30, 2017	71%	29%
For the six months ended June 30, 2017	68%	32%

Specific Factors Affecting Our Results

Sales

Our gross sales are derived from the sales of potash, Trio^® and water and are determined by the quantities of product we sell and the sales prices we realize. For potash and Trio^®, 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 on a portion of our sales as some of our customers arrange and pay for their own freight directly. When we arrange and pay for freight, our quotes and billings are based on expected freight costs to the points of delivery. Although our gross sales include the freight that we bill, we do not believe that gross sales provide a representative measure of our performance in the market due to variations caused by ongoing changes in the proportion of customers paying for their own freight, the geographic distribution of our products, and freight rates. Freight rates have been steadily increasing, thereby negatively influencing our average net realized sales price. Additionally, international freight costs per ton are significantly higher than domestic freight costs per ton. We manage our sales and marketing operations centrally, and we work to achieve the highest average net realized sales price we can by evaluating the product needs of our customers and associated logistics and then determining which of our production facilities can best satisfy these needs. Water sales are based on negotiated contractual per barrel rates multiplied by the number of barrels delivered to the customer.

The volume of product we sell is determined by demand for our products, our inventory storage capabilities and by our production capabilities. We generally intend to operate our facilities at production levels that approximate expected demand. By having adequate warehouse capacity, we can maintain production levels during periods of fluctuating product demand and have product inventory positioned closer to the fields in order to meet peak periods of fertilizer demand.

24

Cost of Goods Sold

Our cost of goods sold reflects costs to produce our potash and Trio^® products, less credits generated from the sale of our by-products, and costs incurred to provide water to customers. Many of our potash and Trio^® production costs are largely fixed, and, consequently, our cost of goods sold per ton on a facility-by-facility basis tends to move inversely with the number of tons we produce, within the context of normal production levels. Our solar solution production is impacted by weather variability. Our principal production costs include labor and employee benefits, maintenance materials, contract labor, materials for operating or maintenance projects, natural gas, electricity, operating supplies, chemicals, depreciation and depletion, royalties, and leasing costs. A smaller component of our cost base includes variable costs associated with contract labor, consumable operating supplies, reagents, and royalties. Our periodic production costs and costs of goods sold will not necessarily match one another from period to period based on the fluctuation of inventory, sales, production levels at our facilities, and sales of by-products.

Our production costs are also impacted when our production levels change, due to factors such as changes in the grade of ore mined, levels of Trio^® mine development, plant operating performance, downtime, and periodic maintenance turnarounds. We expect that our labor and contract labor costs in Carlsbad, New Mexico, will continue to be influenced most directly by the demand for labor in the local region where we compete for labor with the oil and gas, mining, and nuclear waste storage industries.

We pay royalties to federal, state, and private lessors under our mineral leases. These payments typically equal a percentage of sales, after subtracting freight costs, of minerals extracted and sold under the applicable lease. In some cases, federal royalties for potash are paid on a sliding scale that varies with the grade of ore extracted. For the three and six months ended June 30, 2018, our average royalty rate was 4.3%. For both the three and six months ended June 30, 2017, our average royalty rate was 4.5%.

Income Taxes

We are subject to federal and state income taxes on our taxable income. Our effective tax rate for both the three and six months ended June 30, 2018, and 2017 approximated zero. Our effective tax rates were impacted primarily due to the valuation allowance established to offset our deferred tax assets.

Our federal and state income tax returns are subject to examination by federal and state tax authorities.

For the three and six months ended June 30, 2018, and 2017, we incurred immaterial amounts of income tax expense.

We evaluate our deferred tax assets and liabilities each reporting period using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax liability or asset is expected to be settled or realized. The estimated statutory income tax rates that are applied to our current and deferred income tax calculations are impacted most significantly by the states in which we conduct business. Changing business conditions for normal business transactions and operations, as well as changes to state tax rate and apportionment laws, potentially alter our apportionment of income among the states for income tax purposes. These changes in apportionment laws result in changes in the calculation of our current and deferred income taxes, including the valuation of our deferred tax assets and liabilities. The effects of any such changes are recorded in the period of the adjustment. These adjustments can increase or decrease the net deferred tax asset on the balance sheet. However, any resulting impact to the deferred tax benefit or deferred tax expense would be offset by a corresponding adjustment to the valuation allowance and would have no income statement effect.

Capital Investments

During the first six months of 2018, cash paid for property, plant and equipment was $8.9 million. We expect total capital investment for 2018 to be approximately $14 million to $18 million. We expect the majority of our capital investment in 2018 to be sustaining capital. We anticipate our remaining 2018 operating plans and capital programs will be funded out of operating cash flows and existing cash. We may also use our revolving credit facility, to the extent available, to fund capital investments.

Liquidity and Capital Resources

As of June 30, 2018, we had cash of $26.2 million, compared with cash of $1.1 million at December 31, 2017.

Our operations have primarily been funded from cash generated by operations. We continue to monitor our future sources and uses of cash, and anticipate that we will adjust our capital allocation strategies when, and if, determined by our Board of Directors. We expect to continue to look for opportunities to improve our capital structure by reducing current debt and its related interest expense. We may, at any time we deem conditions favorable, also attempt to improve our liquidity position by accessing debt or equity markets, including through our at-the-market offering program, in accordance with our

25

existing debt agreements. We cannot provide any assurance that we will pursue any of these transactions or that we will be successful in completing them on acceptable terms or at all. With the availability under our credit facility and expected future cash generated from operations, we believe that we have sufficient liquidity for the next twelve months.

The following summarizes our cash flow activity for the six months ended June 30, 2018, and 2017 (in thousands):

	Six Months Ended June 30,
	2018			2017
Cash flows provided by operating activities	$	38,176		$	7,984
Cash flows (used in) provided by investing activities	$	(8,786	)	$	1,995
Cash flows used in financing activities	$	(4,224	)	$	(11,778	)

Operating Activities

Total cash provided by operating activities through June 30, 2018, was $38.2 million, an increase of $30.2 million compared with the first six months of 2017. The increase was driven by higher potash average net realized sales price per ton, increased water and by-product sales and decreased inventory during the first six months of 2018.

Investing Activities

Total cash used in investing activities increased by $10.8 million in the first six months of 2018, compared with the same period in 2017. Cash capital expenditures increased by $5.3 million during the first six months of 2018, due mainly to construction of capital projects designed to increase water and by-product sales. During the first six months of 2017, we sold an asset and received approximately $5.5 million in cash proceeds.

Financing Activities

Total cash used in financing activities decreased by $7.6 million in the first six months of 2018, compared with the same period in 2017. In the first half of 2017, we issued 50.1 million shares of common stock in an underwritten public offering for net proceeds of $57.5 million. Proceeds from the underwritten public offering were used in part of repay $69 million of indebtedness during the first six months of 2017. In 2018, financing activities consisted of net repayments of short-term borrowings on our credit facility.

Senior Notes

As of June 30, 2018, we had outstanding $60 million of senior notes (the "Notes") consisting of the following series:

• $24 million of Senior Notes, Series A, due April 16, 2020

• $18 million of Senior Notes, Series B, due April 14, 2023

• $18 million of Senior Notes, Series C, due April 16, 2025

We are required to prepay $10 million in principal of the Notes, plus accrued interest and a make-whole amount, on or before December 31, 2018.

The agreement governing the Notes contains certain financial covenants, including the following:

• For the quarters ended June 30, 2018, and ending September 30, 2018, we were and are required to maintain a minimum fixed charge coverage amount of negative $15 million and negative $10 million, respectively. Thereafter, we are required to maintain a minimum fixed charge coverage ratio that starts at 0.25 to 1.0 for the quarter ending December 31, 2018, and increases to 1.3 to 1.0 for each quarter ending on or after September 30, 2019. As of June 30, 2018, our fixed charge coverage amount was $21.9 million, and our fixed charge coverage ratio was 8.6 to 1.0.

• We are required to maintain a maximum leverage ratio that started at 11.5 to 1.0 for the quarter ended June 30, 2018, and decreases each quarter until it reaches 3.5 to 1.0 for each quarter ending on or after September 30, 2019. As of June 30, 2018, our leverage ratio was 1.5 to 1.0.

Fixed charge coverage amount, fixed charge coverage ratio, and leverage ratio are calculated in accordance with the agreement governing the Notes.

For the six months ended June 30, 2018, the interest rates on the Notes were 3.73% for the Series A Notes, 4.63% for the Series B Notes and 4.78% for the Series C Notes. These rates represent the lowest interest rates available under the Notes. The interest rates may adjust upward if we do not continue to meet certain financial covenants.

26

We have granted to the collateral agent for the noteholders a first lien on substantially all of our non-current assets and second lien on substantially all of our current assets. We are required to offer to prepay the Notes with the proceeds of dispositions of certain specified property and with the proceeds of certain equity issuances, as set forth in the agreement. The obligations under the Notes are unconditionally guaranteed by several of our subsidiaries.

We were in compliance with the applicable covenants under the agreement governing the Notes as of June 30, 2018.

Our outstanding long-term debt, net, as of June 30, 2018, and December 31, 2017, is as follows (in thousands):

	June 30, 2018			December 31, 2017
Senior Notes	$	60,000		$	60,000
Less current portion of long-term debt	(10,000		)	(10,000		)
Less deferred financing costs	(496		)	(563		)
Long-term debt, net	$	49,504		$	49,437

Credit Facility—We maintain an asset-based revolving credit facility with Bank of Montreal that matures on October 31, 2019. The credit facility allows us to borrow up to $35 million subject to monthly limits based on our inventory and receivables. We can use up to $10 million of borrowings under the agreement to make payments on the Notes.

Borrowings on the credit facility bear interest at 1.75% to 2.25% above LIBOR (London Interbank Offered Rate), based on average availability under the credit facility. We have granted to Bank of Montreal a first lien on substantially all of our current assets and a second lien on substantially all of our non-current assets.

We regularly borrow and repay amounts under the facility for near-term working capital needs and may do so in the future. For the six months ended June 30, 2018, we borrowed $13.5 million and repaid $17.4 million under the facility. As of June 30, 2018, we had no borrowings outstanding and $3.8 million in outstanding letters of credit under the facility. Considering the outstanding letters of credit, we had $25.7 million available under the facility as of June 30, 2018. We were in compliance with the applicable covenants under the facility as of June 30, 2018.

At-the-Market Offering Program

In May 2017, we established an at-the-market offering program, which gives us the capacity to issue up to $40 million of our common stock. We did not issue any shares under our at-the-market program during the first half of 2018. At June 30, 2018, we have remaining capacity to issue and sell up to $37.8 million of additional shares of common stock under the program.

Off-Balance Sheet Arrangements

As of June 30, 2018, we had no material off-balance sheet arrangements aside from the operating leases and bonding obligations described in the accompanying notes to the condensed consolidated financial statements.

Critical Accounting Policies and Estimates

Our Annual Report on Form 10-K for the year ended December 31, 2017,describes the critical accounting policies that affect our more significant judgments and estimates used in the preparation of our consolidated financial statements. Except for the accounting policies for revenue recognition that were updated as a result of adopting ASC Topic 606 on January 1, 2018, as discussed in Note 2 to the condensed consolidated financial statements, there have been no significant changes to our critical accounting policies since December 31, 2017.

Non-GAAP Financial Measure

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use average net realized sales price per ton, a non-GAAP financial measure to monitor, and evaluate our performance. This non-GAAP financial measure 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 this non-GAAP financial measure varies among companies, our non-GAAP financial measure may not be comparable to similarly titled measures used by other companies.

27

We believe average net realized sales price per ton provides useful information to investors for analysis of our business. We use this non-GAAP financial measure as one of our tools in comparing period-over-period performance on a consistent basis and when planning, forecasting, and analyzing future periods. We believe this non-GAAP financial measure is 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.     

Average Net Realized Sales Price per Ton

Average net realized sales price per ton is calculated as sales, less freight costs, divided by the number of tons sold in the period. We consider 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 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 average net realized sales price per ton as a key performance indicator to analyze sales and price trends.

Below is a reconciliation of average net realized sales price per ton to the most directly comparable GAAP measure for the three and six months ended June 30, 2018, and 2017:

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Part II, Item 7A., "Quantitative and Qualitative Disclosure About Market Risk," of our Annual Report on Form 10-K for the year ended December 31, 2017, describes our exposure to market risk. There have been no significant changes to our market risk exposure since December 31, 2017.

ITEM 4.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

28

We maintain "disclosure controls and procedures," as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act. Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms. Our disclosure controls and procedures are also designed to ensure that this information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including our principal executive offer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures as of June 30, 2018. Based on this evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of June 30, 2018, at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and principal financial officer, do not expect that our disclosure controls or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Intrepid have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In February 2015, Mosaic Potash Carlsbad Inc. (“Mosaic”) filed a complaint and application for preliminary injunction and permanent injunction against Steve Gamble and us in the Fifth Judicial District Court for the County of Eddy in the State of New Mexico. In August 2015, the court denied Mosaic’s application for preliminary injunction. In July 2016, Mosaic filed a second complaint against Mr. Gamble and us in US District Court for the District of New Mexico. In January 2018, the two lawsuits were consolidated into one lawsuit pending in the US District Court for the District of New Mexico.  Mr. Gamble is a former employee of Intrepid and Mosaic. Mosaic alleges against us violations of the New Mexico Uniform Trade Secrets Act, tortious interference with contract relating to Mr. Gamble’s separation of employment from Mosaic, violations of the Computer Fraud and Abuse Act, conversion, and civil conspiracy relating to the alleged misappropriation of Mosaic’s confidential information and related actions.  Mosaic seeks monetary relief of an unspecified amount, including damages for actual loss and unjust enrichment, exemplary damages, attorneys’ fees, and injunctive relief and has alleged that it has spent hundreds of millions of dollars to research and develop its alleged trade secrets.  The lawsuit is progressing through discovery.  We are vigorously defending against the lawsuit.

We are also subject to other claims and legal actions in the ordinary course of business. While there are uncertainties in predicting the outcome of any claim or legal action, we believe that the ultimate resolution of these other claims or actions is not reasonably likely to have a material adverse effect on our financial condition, results of operations, or cash flows.

ITEM 1A. RISK FACTORS

Our future performance is subject to a variety of risks and uncertainties that could materially and adversely affect our business, financial condition, results of operations, and the trading price of our common stock. These risks and uncertainties are described in Part I, Item 1A. "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2017. There have been no material changes to these risks and uncertainties described in our Annual Report on Form 10-K for the year ended December 31, 2017.

ITEM 4.MINE SAFETY DISCLOSURES

We are committed to providing a safe and healthy work environment. The objectives of our safety programs are to eliminate workplace accidents and incidents, preserve employee health, and comply with safety- and health-based regulations. We seek to achieve these objectives by training employees in safe work practices; establishing, following, and improving safety standards; involving employees in safety processes; openly communicating with employees about safety matters; and recording, reporting, and investigating accidents, incidents, and losses to avoid recurrence. As part of our ongoing safety programs, we collaborate with regulators to identify and implement new accident prevention techniques and practices.

Our East, West and North facilities in New Mexico are subject to regulation by the Mine Safety and Health Administration ("MSHA") under the Federal Mine Safety and Health Act of 1977 and the New Mexico Bureau of Mine Safety. MSHA inspects these facilities on a regular basis and issues citations and orders when it believes a violation has occurred under federal law. Exhibit 95.1 to this Quarterly Report on Form 10-Q provides the information concerning mine safety violations and other regulatory matters required by SEC rules. Our Utah and HB facilities are subject to regulation by the Occupational Health and Safety Administration and, therefore, are not required to be included in the information provided in Exhibit 95.1.

EX-95.1

Exhibit 95.1

The table below provides information for the quarter ended June 30, 2018, about certain mine safety and health citations issued to Intrepid or its subsidiaries by the Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”) and about certain other regulatory matters.

Mine Name and MSHA Identification Number	Section 104 S&S Citations	Section 104(b) Orders	Section 104(d) Citations and Orders	Section 110(b)(2) Violations	Section 107(a) Orders	Total Dollar Value of MSHA Assessments Proposed	Total Number of Mining-Related Fatalities	Received Notice of Pattern of Violations Under Section 104(e)	Received Notice of Potential to Have Pattern under Section 104(e)	Legal Actions Pending as of the End of the Period	Legal Actions Initiated During the Period	Legal Actions Resolved During the Period
Intrepid Potash East (29-00170)	—	—	—	—	—	$6,102	—	—	—	—	—	2
Intrepid Potash West (29-00175)	—	—	—	—	—	$590	—	—	—	2	1	—
Intrepid Potash North (29-02028)	1	—	—	—	—	$826	—	—	—	—	—	—

Below are additional details about the information provided in the table above:

• General - In general, the number of citations and orders will vary depending on the size of the mine, the individual inspector assigned to the mine, and the specific mine characteristics. Citations and orders can be contested and appealed and, in that process, are often reduced in severity and amount and are sometimes vacated.

• MSHA Identification Numbers - MSHA assigns an identification number to each mine and may or may not assign separate identification numbers to related facilities. We provide the information in the table by MSHA identification number.

• Section 104 Significant and Substantial (“S&S”) Citations - These citations are issued for alleged violations of a mining safety standard or regulation where there exists a reasonable likelihood that the hazard contributed to or will result in an injury or illness of a reasonably serious nature.

• Section 104(b) Orders - These orders are issued for alleged failure to totally abate the subject matter of a Section 104(a) citation within the period specified in the citation.

• Section 104(d) Citations and Orders - These citations and orders are issued for an alleged unwarrantable failure (i.e., aggravated conduct constituting more than ordinary negligence) to comply with a mining safety standard or regulation.

• Section 110(b)(2) Violations - These violations are issued, and penalties are assessed, for flagrant violations (i.e., a reckless or repeated failure to make reasonable efforts to eliminate a known violation that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury).

• Section 107(a) Orders - These orders are issued for an imminent danger to immediately remove miners.

• Total Dollar Value of MSHA Assessments Proposed - Proposed assessments issued during the period do not necessarily relate to the citations or orders issued by MSHA during that period or to the pending legal actions reported in the table.

• Notice of Pattern of Violations Under Section 104(e); Notice of Potential to Have Pattern under Section 104(e) - These notices are issued for a pattern of violation of mandatory health or safety standards or for the potential to have such a pattern.

• Legal Actions Pending, Initiated, and Resolved - The Federal Mine Safety and Health Review Commission (the “Commission”) is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. Each legal action is assigned a docket number by the Commission and may have as its subject matter one or more citations, orders, penalties, or complaints.

The table below summarizes the types of legal actions that were pending as of June 30, 2018:

Mine Name and MSHA Identification Number	Contests of Citations and Orders	Contests of Proposed Penalties	Complaints for Compensation	Complaints of Discharge, Discrimination or Interference	Applications for Temporary Relief	Appeals of Judges’ Decisions or Orders	Total
Intrepid Potash East (29-00170)	—	—	—	—	—	—	—
Intrepid Potash West (29-00175)	2	—	—	—	—	—	2
Intrepid Potash North (29-02028)	—	—	—	—	—	—	—

COMPANY BACKGROUND

COMPANY BACKGROUND

We are the only producer of muriate of potash ("potassium chloride" or "potash") in the United States and are one of two producers of langbeinite ("sulfate of potash magnesia"), which we market and sell as Trio^®. We sell potash and Trio^® primarily into the agricultural market as a fertilizer. We also sell these products into the animal feed market as a nutritional supplement and sell potash into the industrial market as a component in drilling and fracturing fluids for oil and gas wells and other industrial inputs. We also sell water, primarily for industrial uses such as in the oil and gas industry. In addition, we sell by-products including salt, magnesium chloride, and brine, which are recorded as a credit to cost of goods sold. These by-product credits represented approximately 9% of total cost of goods sold for the six months ended June 30, 2018.

We produce potash from three solution mining facilities: our HB solar solution mine in Carlsbad, New Mexico, our solar solution mine in Moab, Utah, and our solar brine recovery mine in Wendover, Utah. We also operate the North compaction facility in Carlsbad, New Mexico, which compacts and granulates product from the HB mine. We produce Trio^® from our conventional underground East mine in Carlsbad, New Mexico.

"Intrepid," "our," "we," or "us," means Intrepid Potash, Inc. and its consolidated subsidiaries.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Financial Statement Presentation—Our unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation of interim financial information, have been included. These condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC on February 27, 2018.

Except for the accounting policies for revenue recognition that were updated as a result of adopting Accounting Standards Codification ("ASC") 606 "Revenue from Contracts with Customers" ("ASC Topic 606"), there have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2017.

Revenue Recognition—The majority of our revenue is derived from contract sales that are of a short-term nature. We account for revenue in accordance with ASC Topic 606, which we adopted on January 1, 2018, using the full retrospective method. Comparative information has been adjusted as if ASC Topic 606 was in effect during the comparative period. See Note 16 "Recently Adopted Accounting Pronouncements" for further discussion of the adoptions, including the retrospective adjustment made to our 2017 financial information.

Performance Obligations: A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606. The contract's transaction price is allocated to the performance obligations and recognized as revenue when the performance obligations are satisfied. Generally, our performance obligations are satisfied when we ship product from our facility to the customer. Shipping and handling charges are accounted for as a fulfillment cost and, as such, are not considered to be a separate performance obligation. Revenue from sales to customers at a single point in time accounted for all our revenue for the three and six months ended June 30, 2018, and 2017.

Contract Estimates: In certain circumstances, we may sell product to customers where the sales price is variable. For such sales, we estimate the sales price we expect to realize based on the facts and circumstances for each sale, including historical experience, and recognize revenue to the extent it is probable that a subsequent change in estimate will not result in a significant revenue reversal compared to the cumulative revenue recognized under the contract.

Contract Balances: The timing of revenue recognition, billings and cash collection may result in contract assets or contract liabilities. For certain contracts, the customer has agreed to pay us before we have satisfied our performance obligations. Customer payments received before we have satisfied our performance obligations are accounted for as a contract liability. As of June 30, 2018, we had $7.3 million in contract liabilities which are included in "Other current liabilities" on the condensed consolidated balance sheets. We had no contract liabilities at December 31, 2017. For the three and six months ended June 30, 2018, we recognized $0.5 million of revenue as the performance obligation was satisfied.

Disaggregation of Revenue: In the following table, revenue is disaggregated by our primary products.

	Three Months Ended June 30,
	2018		2017
Product (amounts in thousands)	Revenue		Revenue		Timing of revenue recognition

Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period. For purposes of determining diluted earnings per share, basic weighted-average common shares outstanding are adjusted to include potentially dilutive securities, including restricted stock, stock options, and performance units. The treasury-stock method is used to measure the dilutive impact of potentially dilutive shares. Potentially dilutive shares are excluded from the diluted weighted-average shares outstanding computation in periods in which they have an anti-dilutive effect. The following table shows the calculation of basic and diluted earnings (loss) per share (in thousands, except per share amounts):

	Three Months Ended June 30,						Six Months Ended June 30,

DEBT

Senior Notes—As of June 30, 2018, we had outstanding $60 million of senior notes (the "Notes") consisting of the following series:

• $24 million of Senior Notes, Series A, due April 16, 2020

• $18 million of Senior Notes, Series B, due April 14, 2023

• $18 million of Senior Notes, Series C, due April 16, 2025

We are required to prepay $10 million in principal of the Notes, plus accrued interest and a make-whole amount, on or before December 31, 2018.

The agreement governing the Notes contains certain financial covenants, including the following:

• For the quarters ended June 30, 2018, and ending September 30, 2018, we were and are required to maintain a minimum fixed charge coverage amount of negative $15 million and negative $10 million, respectively. Thereafter, we are required to maintain a minimum fixed charge coverage ratio that starts at 0.25 to 1.0 for the quarter ending December 31, 2018, and increases to 1.3 to 1.0 for each quarter ending on or after September 30, 2019. As of June 30, 2018, we were in compliance with these financial covenants as our fixed charge coverage amount was $21.9 million, and our fixed charge coverage ratio was 8.6 to 1.0.

• We are required to maintain a maximum leverage ratio that started at 11.5 to 1.0 for the quarter ended June 30, 2018, and decreases each quarter until it reaches 3.5 to 1.0 for each quarter ending on or after September 30, 2019. As of June 30, 2018, our leverage ratio was 1.5 to 1.0.

Fixed charge coverage amount, fixed charge coverage ratio, and leverage ratio are calculated in accordance with the agreement governing the Notes.

For the three and six months ended June 30, 2018, the interest rates on the Notes were 3.73% for the Series A Notes, 4.63% for the Series B Notes and 4.78% for the Series C Notes. These rates represent the lowest interest rates available under the Notes. The interest rates may adjust upward if we do not continue to meet certain financial covenants.

We have granted to the collateral agent for the noteholders a first lien on substantially all of our non-current assets and a second lien on substantially all of our current assets. We are required to offer to prepay the Notes with the proceeds of dispositions of certain specified property and with the proceeds of certain equity issuances, as set forth in the agreement. The obligations under the Notes are unconditionally guaranteed by several of our subsidiaries.

We were in compliance with the applicable covenants under the agreement governing the Notes as of June 30, 2018.

Our outstanding long-term debt, net, as of June 30, 2018, and December 31, 2017, is as follows (in thousands):

	June 30, 2018			December 31, 2017
Senior Notes	$	60,000		$	60,000
Less current portion of long-term debt	(10,000		)	(10,000		)
Less deferred financing costs	(496		)	(563		)
Long-term debt, net	$	49,504		$	49,437

Credit Facility—We maintain an asset-based revolving credit facility with Bank of Montreal that matures on October 31, 2019. The credit facility allows us to borrow up to $35 million subject to monthly limits based on our inventory and receivables. We can use up to $10 million of borrowings under the agreement to make payments on the Notes.

Borrowings on the credit facility bear interest at 1.75% to 2.25% above LIBOR (London Interbank Offered Rate), based on average availability under the credit facility. We have granted to Bank of Montreal a first lien on substantially all of our current assets and a second lien on substantially all of our non-current assets.

We regularly borrow and repay amounts under the facility for near-term working capital needs and may do so in the future. For the three months ended June 30, 2018, we had no borrowings and repaid $1.5 million under the facility. For the six months ended June 30, 2018, we borrowed $13.5 million and repaid $17.4 million under the facility. As of June 30, 2018, we had no borrowings outstanding and $3.8 million in outstanding letters of credit under the facility. Considering the outstanding letters of credit, we have $25.7 million available under the facility as of June 30, 2018. We were in compliance with the applicable covenants under the facility as of June 30, 2018.

Asset Retirement Obligation Disclosure [Abstract]

ASSET RETIREMENT OBLIGATION

ASSET RETIREMENT OBLIGATION

We recognize an estimated liability for future costs associated with the abandonment and reclamation of our mining properties. A liability for the fair value of an asset retirement obligation and a corresponding increase to the carrying value of the related long-lived asset are recorded as the mining operations occur or the assets are acquired.

Our asset retirement obligation is based on the estimated cost to abandon and reclaim the mining operations, the economic life of the properties, and federal and state regulatory requirements. The liability is discounted using credit adjusted risk-free rate estimates at the time the liability is incurred or when there are upward revisions to estimated costs. The credit adjusted risk-free rates used to discount our abandonment liabilities range from 6.9% to 9.7%. Revisions to the liability occur due to construction of new or expanded facilities, changes in estimated abandonment costs or economic lives, or if federal or state regulators enact new requirements regarding the abandonment or reclamation of mines.

Following is a table of the changes to our asset retirement obligation for the following periods (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Asset retirement obligation, at beginning of period	$	21,893	$	20,365	$	21,476	$	19,976

Total asset retirement obligation, at end of period	$	22,310	$	20,754	$	22,310	$	20,754

The undiscounted amount of asset retirement obligation was $59.5 million as of June 30, 2018.

COMPENSATION PLANS

COMPENSATION PLANS

Equity Incentive Compensation Plan—Our Board of Directors and stockholders adopted a long-term incentive compensation plan called the Intrepid Potash, Inc. Amended and Restated Equity Incentive Plan (the "Plan"). We have issued common stock, restricted stock, performance units, and non-qualified stock option awards under the Plan. At June 30, 2018, there were approximately 2.3 million shares available for issuance under the Plan.

For the three months ended June 30, 2018, we granted to members of our Board of Directors 0.1 million shares of restricted stock, which vest one year from the date of the grant.

For the six months ended June 30, 2018, we granted 0.5 million shares of restricted stock and 1.6 million non-qualified stock options to members of our Board of Directors, executive officers, and other key employees. These awards vest one to three years from the date of the grant, and in some cases, contain performance-vesting conditions or market conditions.

As of June 30, 2018, the following awards were outstanding under the Plan:

	Outstanding as of June 30, 2018
Restricted Stock	2,903,388
Non-qualified Stock Options	3,574,198

Total share-based compensation expense was $1.3 million and $0.7 million for the three months ended June 30, 2018, and 2017, respectively. For the six months ended June 30, 2018, and 2017, total share-based compensation expense was $2.3 million and $1.7 million, respectively. As of June 30, 2018, we had $8.1 million of total remaining unrecognized compensation expense related to awards, that will be expensed through 2021.

INCOME TAXES

INCOME TAXES

Our anticipated annual tax rate is impacted primarily by the amount of taxable income associated with each jurisdiction in which our income is subject to income tax, permanent differences between the financial statement carrying amounts and tax bases of assets and liabilities.

During both the three and six months ended June 30, 2018, and June 30, 2017, we incurred an immaterial amount of income tax expense. Our effective tax rate was 0% for both the three and six months ended June 30, 2018, and 2017, which differed from the statutory rate primarily due to the valuation allowance established to offset our deferred tax assets.

As of June 30, 2018, we do not believe it is more likely than not that we will fully realize the benefit of our deferred tax assets. As such, we maintained a full valuation allowance against our net deferred tax assets as of June 30, 2018, and December 31, 2017.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

Reclamation Deposits and Surety Bonds—As of June 30, 2018, and December 31, 2017, we had $18.8 million of security placed principally with the State of Utah and the Bureau of Land Management for eventual reclamation of our various facilities. Of this total requirement, as of June 30, 2018, and December 31, 2017, $0.5 million consisted of long-term restricted cash deposits reflected in "Other assets, net" on the condensed consolidated balance sheets and $18.3 million was secured by surety bonds issued by an insurer. The surety bonds are held in place by an annual fee paid to the issuer.

We may be required to post additional security to fund future reclamation obligations as reclamation plans are updated or as governmental entities change requirements.

Legal—In February 2015, Mosaic Potash Carlsbad Inc. (“Mosaic”) filed a complaint and application for preliminary injunction and permanent injunction against Steve Gamble and us in the Fifth Judicial District Court for the County of Eddy in the State of New Mexico. In August 2015, the court denied Mosaic’s application for preliminary injunction. In July 2016, Mosaic filed a second complaint against Mr. Gamble and us in US District Court for the District of New Mexico. In January 2018, the two lawsuits were consolidated into one lawsuit pending in the US District Court for the District of New Mexico.  Mr. Gamble is a former employee of Intrepid and Mosaic. Mosaic alleges against us violations of the New Mexico Uniform Trade Secrets Act, tortious interference with contract relating to Mr. Gamble’s separation of employment from Mosaic, violations of the Computer Fraud and Abuse Act, conversion, and civil conspiracy relating to the alleged misappropriation of Mosaic’s confidential information and related actions.  Mosaic seeks monetary relief of an unspecified amount, including damages for actual loss and unjust enrichment, exemplary damages, attorneys’ fees, and injunctive relief and has alleged that it has spent hundreds of millions of dollars to research and develop its alleged trade secrets.  The lawsuit is progressing through discovery.  We are vigorously defending against the lawsuit. Because this matter is at an early stage, we are unable to reasonably estimate the potential amount of loss, if any.

We are also subject to other claims and legal actions in the ordinary course of business. Legal costs are expensed as incurred. While there are uncertainties in predicting the outcome of any claim or legal action, we believe that the ultimate resolution of these other claims or actions is not reasonably likely to have a material adverse effect on our financial condition, results of operations, or cash flows.

Other—In May 2018, one of our water customers claimed that its water-metering equipment was not working properly in March 2018 and April 2018, thereby resulting in the customer overreporting its water use by approximately $1.7 million. We are working with the customer to determine the correct amount of water used. Although we have not completed this process, we believe it is probable that the customer overreported its water use and have estimated the overreported amount to range between $0.6 million to $1.7 million. As such, we recorded $0.6 million of operating expense in the second quarter of 2018, for a contingent liability relating to this matter.

Future Operating Lease Commitments—We have operating leases for land, mining and other operating equipment, offices, and railcars, with original terms ranging up to 30 years.

Rental and lease expenses for the three months ended June 30, 2018, and 2017, were $1.0 million and $1.5 million, respectively. Rental and lease expenses for the six months ended June 30, 2018, and 2017, were $2 million and $3 million, respectively.

FAIR VALUE MEASUREMENTS

FAIR VALUE

We measure our financial assets and liabilities in accordance with Accounting Standards Codification™ ("ASC") Topic 820, Fair Value Measurements and Disclosures.

As of June 30, 2018, and December 31, 2017, our cash consisted of bank deposits. Other financial assets and liabilities including accounts receivable, refundable income taxes, accounts payable, accrued liabilities, and advances on credit facility are carried at cost which approximates fair value because of the short-term nature of these instruments.

As of June 30, 2018, and December 31, 2017, the estimated fair value of our outstanding Notes was $55.9 million and $58.8 million, respectively. The fair value of our Notes is estimated using a discounted cash flow analysis based on current borrowing rates for debt with similar remaining maturities and ratings (a Level 2 input) and is designed to approximate the amount at which the instruments could be exchanged in an arm's-length transaction between knowledgeable willing parties.

RECENT ACCOUNTING PRONOUNCEMENTS

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

RECENT ACCOUNTING PRONOUNCEMENTS

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, as amended by ASU No. 2016-12, "Revenue from Contracts with Customers (Topic 606)," which requires revenue to be recognized based on the amount an entity is expected to be entitled to for promised goods or services provided to customers. The standard also requires expanded disclosures regarding contracts with customers. This standard became effective for us beginning January 1, 2018.

Our revenue predominantly continues to be recognized when products are shipped from our manufacturing facilities. Under the new revenue standard, certain sales where revenue was previously deferred, such as sales in which the final price was not fixed and determinable, we now recognize revenue when the product is shipped using the sales price we expect to realize. In conjunction with our adoption of Topic 606 on January 1, 2018, primarily related to variable pricing contracts, we recorded a net increase to opening retained deficit of $0.5 million.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230)" which is intended to clarify and align how certain cash receipts and cash payments are presented and classified in the statement of cash flows where there is currently diversity in practice. ASU No. 2016-15 specifically addresses eight classification issues within the statement of cash flows including debt prepayments or debt extinguishment costs; proceeds from the settlement of insurance claims; and separately identifiable cash flows and application of the predominance principle. This standard became effective for us beginning January 1, 2018. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.

    In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740)" which became effective for us beginning January 1, 2018. This standard requires us to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" which became effective for us beginning January 1, 2018. This standard requires us to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows and will no longer require transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. As a result of including restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts presented on the condensed consolidated statement of cash flows, net cash flows for the six months ended June 30, 2017, decreased by $3.5 million.

Pronouncements Issued But Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires, among other things, lessees to recognize lease assets and liabilities on their balance sheets for those leases classified as operating leases under previous generally accepted accounting principles. These assets and liabilities must be recorded generally at the present value of the contracted lease payments, and the cost of the lease must be allocated over the lease term on a straight-line basis. This guidance is effective for us for annual and interim periods in fiscal years beginning after December 15, 2018, with a modified retrospective transition method mandated.

We are continuing to work on ensuring we have identified all potential leases. We estimate additional assets and liabilities recorded after adoption of ASU No. 2016-02, "Leases (Topic 842)" will be less than $10 million.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - (Topic 326): Measurement of Credit Losses on Financial Instruments," which changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. This guidance is effective for us for annual and interim periods in fiscal years beginning after December 15, 2018. Because we have historically experienced minimal bad debt expense related to our trade receivables, we do not believe the adoption of this new standard will have a material impact on our condensed consolidated financial statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

6 Months Ended

Jun. 30, 2018

Accounting Policies [Abstract]

Financial Statement Presentation

Our unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation of interim financial information, have been included. These condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC on February 27, 2018.

Except for the accounting policies for revenue recognition that were updated as a result of adopting Accounting Standards Codification ("ASC") 606 "Revenue from Contracts with Customers" ("ASC Topic 606"), there have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2017.

Revenue Recognition

The majority of our revenue is derived from contract sales that are of a short-term nature. We account for revenue in accordance with ASC Topic 606, which we adopted on January 1, 2018, using the full retrospective method. Comparative information has been adjusted as if ASC Topic 606 was in effect during the comparative period. See Note 16 "Recently Adopted Accounting Pronouncements" for further discussion of the adoptions, including the retrospective adjustment made to our 2017 financial information.

Performance Obligation

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606. The contract's transaction price is allocated to the performance obligations and recognized as revenue when the performance obligations are satisfied. Generally, our performance obligations are satisfied when we ship product from our facility to the customer. Shipping and handling charges are accounted for as a fulfillment cost and, as such, are not considered to be a separate performance obligation. Revenue from sales to customers at a single point in time accounted for all our revenue for the three and six months ended June 30, 2018, and 2017.

Contract Estimates

In certain circumstances, we may sell product to customers where the sales price is variable. For such sales, we estimate the sales price we expect to realize based on the facts and circumstances for each sale, including historical experience, and recognize revenue to the extent it is probable that a subsequent change in estimate will not result in a significant revenue reversal compared to the cumulative revenue recognized under the contract.

Contract Balances

The timing of revenue recognition, billings and cash collection may result in contract assets or contract liabilities. For certain contracts, the customer has agreed to pay us before we have satisfied our performance obligations. Customer payments received before we have satisfied our performance obligations are accounted for as a contract liability. As of June 30, 2018, we had $7.3 million in contract liabilities which are included in "Other current liabilities" on the condensed consolidated balance sheets. We had no contract liabilities at December 31, 2017. For the three and six months ended June 30, 2018, we recognized $0.5 million of revenue as the performance obligation was satisfied.

Earnings Per Share [Abstract]

Schedule of Calculation of Basic and Diluted Loss or Earnings Per Share

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period. For purposes of determining diluted earnings per share, basic weighted-average common shares outstanding are adjusted to include potentially dilutive securities, including restricted stock, stock options, and performance units. The treasury-stock method is used to measure the dilutive impact of potentially dilutive shares. Potentially dilutive shares are excluded from the diluted weighted-average shares outstanding computation in periods in which they have an anti-dilutive effect. The following table shows the calculation of basic and diluted earnings (loss) per share (in thousands, except per share amounts):
