Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are an environmental technology company and are principally engaged in the sale of consumable air and water treatment solutions primarily based on AC. Our proprietary AC products enable customers to reduce air, soil, and water contaminants, including mercury, PFAS and other pollutants, to help our customers maximize utilization effectiveness and to improve operating efficiencies to meet the challenges of existing and pending air quality, soil, and water regulations. We manufacture and sell AC and other chemicals used to capture and remove contaminants for coal-fired power generation, industrial and water treatment markets, which we collectively refer to as the advanced purification technologies or "APT" market.

Our primary products are comprised of AC, which is produced from a variety of carbonaceous raw materials. Our AC products include both PAC and GAC. Additionally, we own the Five Forks Mine, a lignite mine that currently supplies the primary raw material for the manufacturing of our products.

In February 2023, we acquired 100% of the equity of the subsidiaries of Arq Limited (hereafter the Arq Limited subsidiaries referred to as "Legacy Arq", and the acquisition itself referred to as the "Arq Acquisition") to secure access to a feedstock, a manufacturing facility and certain patented processes as a means to manufacture additional GAC products for sale into the APT and other markets. With the Arq Acquisition, we now control bituminous coal waste reserves and own a manufacturing facility, both located in Corbin, Kentucky (the "Corbin Facility"), and a process to recover and purify the bituminous coal fines for sale or further conversion to GAC products. Under this manufacturing process, we convert coal waste into a purified, microfine carbon powder known as Arq powderTM ("Arq Powder"). We expect to begin using Arq Powder as a feedstock to begin manufacturing GAC products by the end of 2024 to begin using Arq Powder as a feedstock to produce high-quality GAC products for sale in the APT and other markets.

We believe Arq Powder has additional potential for us to access new markets and applications. We expect to secure customer interest in Arq Powder as an additive into other markets, such as components for asphalt. These products utilizing Arq Powder are expected to have a lower carbon footprint compared to similar products utilizing conventional materials. These applications are currently in various stages of proof of concept testing or preliminary customer testing.

In February 2024, as part of a larger rebranding, the Company changed its name to Arq, Inc., and on February 1, 2024, our common stock commenced trading under the ticker symbol, "ARQ".

Drivers of Demand and Key Factors Affecting Profitability

Drivers of demand and current key factors affecting our profitability are sales of our AC products to the APT market. Our operating results are influenced by: (1) changes in our manufacturing production and sales volumes; (2) changes in price and product mix; (3) changes in coal-fired dispatch and electricity power generation sources and (4) changes in demand for contaminant removal within water treatment facilities.

Components of Revenue, Expenses and Equity Method Investees

The following briefly describes the components of revenue and expenses as presented in the Consolidated Statements of Operations. Descriptions of the revenue recognition policies are included in Note 1 to the Consolidated Financial Statements included in Item 8 of this Report.

Revenue and cost of revenue

Consumables

Our revenue is comprised of the sale of AC products and other chemical-based technology products in the APT market, as well as the sale of other AC products to our largest customer, who services other diverse markets.

Consumables cost of revenue

Consumables cost of revenue is comprised of all labor, fringe benefits, subcontract labor, additive and coal costs, materials, equipment, supplies, travel costs and any other costs and expenses directly related to the cost of production of consumables.

License royalties payable to Tinuum Group

In December 2022, the Company and Tinuum Group entered into an agreement (the "Tinuum Group Royalty Agreement") whereby we pay Tinuum Group a royalty (the "Tinuum Group Royalty") for certain of our sales of M-ProveTM products after the expiration of the tax credit program under IRC Section 45 ("Section 45 Tax Credit Program") (beginning January 1, 2022) to certain of the M-45 Facilities. The Tinuum Group Royalty is calculated based on "Net Profit" (as defined in the Tinuum Royalty Agreement) on our sales of M-ProveTM product to certain of the M-45 Facilities. The Tinuum Group Royalty Agreement is for an initial term of five years with automatic renewals of five years unless we and Tinuum Group agree to terminate it. The Tinuum Group Royalty is included in Consumables cost of revenue.

Other Operating Expenses

Payroll and benefits

Payroll and benefits costs include payroll costs, payroll related fringe benefits and stock based compensation expense of research and development, sales and administrative personnel, but exclude such costs related to direct labor that are included in Cost of revenue.

Legal and professional fees

Legal and professional costs include external legal, audit and consulting expenses.

General and administrative

General and administrative costs include director fees and expenses, bad debt expense, research and development expense and other general costs of conducting business. Research and development costs provided by third parties, net of reimbursements from cost-sharing arrangements, are charged to expense in the period incurred and are reported in the General and administrative line item in the Consolidated Statements of Operations.

Depreciation, amortization, depletion and accretion

Depreciation and amortization expense consists of depreciation expense related to property, plant and equipment and the amortization of long-lived intangible assets. Depletion and accretion expense consists of depletion expense related to the depletion of mine development costs and the accretion of mine reclamation liabilities.

Other Income (Expense), net

Earnings from equity method investments

Earnings from equity method investments represent our share of earnings (losses) related to equity method investments, and in 2023, primarily from Tinuum Group. Through December 31, 2021, we had substantial earnings from Tinuum Group and Tinuum Services, LLC ("Tinuum Services"). With the expiration of the tax credit program under IRC Section 45 afforded to producers of refined coal as of December 31, 2021, both Tinuum Group and Tinuum Services commenced winding down their operations related to the Section 45 tax credit program, although we have recognized earnings in both 2022 and 2023 related to residual cash distributions received.

Other income (expense)

The remaining components of other income (expense) include interest income, interest expense and other miscellaneous items.

Results of Operations

Presentation of Financial Results

For comparison purposes, the following tables set forth our results of operations for the years presented in the Consolidated Financial Statements included in Item 8 of this Report. The year-to-year comparison of financial results is not necessarily indicative of financial results that may be achieved in future years. Our Annual Report on Form 10-K for the year ended December 31, 2023 includes a discussion and analysis of our financial condition and results of operations for the year ended December 31, 2023 compared to the year ended December 31, 2022, disclosed in Item 7 of Part II, "Management’s Discussion and Analysis of Financial Condition and Results of Operations."

Year ended December 31, 2023 Compared to Year ended December 31, 2022

Total Revenue and Cost of Revenue

A summary of the components of revenue and cost of revenue for the years ended December 31, 2023 and 2022 is as follows:

Years Ended December 31,Change
(Amounts in thousands except percentages)20232022($)(%)
Revenue:
Consumables$99,183$102,987$(3,804)(4)%
Total revenue$99,183$102,987$(3,804)(4)%
Consumables cost of revenue, exclusive of depreciation and amortization$67,323$80,465$(13,142)(16)%

Consumables revenue and consumables cost of revenue

For the years ended December 31, 2023 and 2022, consumables revenue decreased year over year primarily driven by lower volumes sold, which comprised $20.0 million of the total change. Product volumes decreased among power generation customers, primarily due to lower natural gas prices compared to 2022, which contributed to decreased utilization of coal-fired generation and decreased demand for our products. Partially offsetting the decrease was an increase due to improved pricing for our products of approximately $10.6 million, $4.7 million of revenue recognized from the settlement of certain contracts with customers containing minimum quantity purchases ("MQ Contacts") and the impact of favorable product mix of approximately $0.7 million.

Consumables gross margin, exclusive of depreciation and amortization, increased for the year ended December 31, 2023 compared to 2022. Driving the increase in gross margin were the impact of the MQ contracts and decreased cost of our feedstock and additives, primarily as a result of decreased production volumes during 2023. Our consumables gross margin was negatively impacted by a decrease in volumes sold.

Consumables revenue continues to be affected by electricity demand, driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation sources such as natural gas and renewables.

Other Operating Expenses

A summary of the components of our operating expenses, exclusive of cost of revenue items (presented above), for the years ended December 31, 2023 and 2022 is as follows:

Other(36)34(70)(206)%
$45,195$34,590$10,60531%

* Calculation not meaningful

Payroll and benefits

Payroll and benefits expenses increased year over year primarily due to the addition of Legacy Arq employees, which increased expenses by $4.9 million for the year, of which $1.1 million related to severance expense of former executives of Legacy Arq. In addition, for the year ended December 31, 2023, we incurred severance related costs of $1.7 million associated with the termination of three executive employees. These increases were partially offset by a decrease in incentive compensation related

28

to non-Legacy Arq employees for the year ended December 31, 2023 of $1.3 million compared to the corresponding period in 2022. An additional decrease in payroll and benefits was due to retention bonuses with our executive officers and certain other key employees of $1.2 million, which were paid in full in January 2023.

Legal and professional fees

Legal and professional fees remained flat year over year.

General and administrative

General and administrative expenses increased for the year ended December 31, 2023 compared to the corresponding period in 2022 as a result of $2.5 million of expenses incurred on behalf of Legacy Arq, which included $1.2 million from rent and occupancy expense from additional leased space. Additional increases period over period of approximately $2.0 million were due to increases in insurance, research and development, travel, recruiting and other outside labor, and director compensation as three new directors were added to the board in connection with the Arq Acquisition.

Depreciation, amortization, depletion and accretion

Depreciation and amortization expense increased for the year ended December 31, 2023 compared to the corresponding period in 2022 primarily due to depreciation and amortization of approximately $2.8 million from the addition of long-lived assets and intangible assets acquired in the Arq Acquisition. Also contributing to the increase was an increase in Depreciation and amortization expense due to higher production volumes compared to sales volumes which resulted in $1.0 million additional absorption of depreciation in inventory.

Gain on sale of Marshall Mine, LLC

As discussed above, for the year ended December 31, 2023, we recognized a gain of $2.7 million on the sale of Marshall Mine, LLC.

Other Income (Expense), net

A summary of the components of our other income (expense), net for the years ended December 31, 2023 and 2022 is as follows:

Years Ended December 31,Change

Earnings from equity method investments$1,623$3,541$(1,918)(54)%

29

Earnings from equity method investments for the year ended December 31, 2023 and 2022 represented cash distributions received from Tinuum Group and Tinuum Services. The decrease was primarily due to Tinuum Group and Tinuum Services continuing to wind down their operations in 2023.

Interest expense

Interest expense increased for the year ended December 31, 2023 compared to the corresponding period in 2022 primarily due to interest expense of $2.0 million related to the $10 million CFG Loan and interest expense of $0.5 million incurred for the same period related to the $10 million CTB Loan assumed by us in the Arq Acquisition.

Other

The increase in Other is primarily driven by interest income of $1.8 million generated from the use of cash sweep accounts in 2023.

Income tax expense

For the year ended December 31, 2023, our reported income tax expense was $0.2 million and was based on an effective rate of (1)%. The difference between our reported income tax expense and the expected federal benefit, as a result of pretax loss recognized for the year ended December 31, 2023, was primarily due to permanent differences related to acquisition-related costs, an increase in the valuation allowance on our deferred tax assets and stock-based compensation.

For the year ended December 31, 2022, our reported income tax expense was $0.2 million and was based on an effective rate of (2)%. The difference between our reported income tax expense and the expected federal benefit, as a result of pretax loss recognized for the year ended December 31, 2023, was primarily due to permanent differences related to acquisition-related costs and an increase in the valuation allowance on our deferred tax assets.

Accounting for income taxes requires that companies assess whether a valuation allowance should be recorded against their deferred tax asset based on an assessment of the amount of the deferred tax asset that is "more likely than not" to be realized. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized.

We assess a valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance for deferred tax assets is appropriate requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize the deferred tax asset, including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of temporary differences and carryforwards, taxable income in carryback years and tax planning strategies. In estimating taxes, we assess the relative merits and risks of the appropriate tax treatment of transactions taking into account statutory, judicial, and regulatory guidance.

As of December 31, 2023, we concluded it is more likely than not we will not generate sufficient taxable income within the allowable carryforward periods to realize any of our net deferred tax assets, and fully reserved for such assets as of December 31, 2023. In reaching this conclusion, we primarily considered forecasts of future taxable losses. As of December 31, 2023 and 2022, we had a valuation allowance of $98.8 million and $88.3 million, respectively, on our deferred tax assets.

The ability to recognize the remaining deferred tax assets that continue to be subject to a valuation allowance is evaluated on a quarterly basis to determine if there are any significant events that would affect the ability to utilize those deferred tax assets. Our estimate of future taxable income or losses is based on internal projections that consider historical performance, assumptions on future performance and external data. If events are identified that affect our ability to utilize our deferred tax assets, or if additional deferred tax assets are generated, we update our analysis to determine if an increase to a valuation allowance is required. Such an increase could have a material adverse effect on our financial condition and results of operations. Conversely, better than expected results and continued positive results and trends could result in a decrease to a valuation allowance, and any such decreases could have a material positive effect on our financial condition and results of operations.

See additional discussion in Note 13 of the Consolidated Financial Statements included in Item 8 of this Report.

Tax Assets

Through December 31, 2021, we earned substantial tax credits under the Section 45 tax credit program, which expired on December 31, 2021. As of December 31, 2023, we had approximately $86.1 million in Section 45 tax credit carryforwards.

30

In the hypothetical event of an "ownership change," as defined by IRC Sections 382, utilization of general business credits ("Tax Credits") generated prior to the change would be subject to an annual limitation imposed by IRC Section 383 for Tax Credits. In connection with the Arq Acquisition and PIPE Investment, we issued additional shares of our common stock. We performed an IRC Section 382 analysis as of the Acquisition Date and determined that we had not experienced an ownership change as of that date.

Prior to the Acquisition Date, Legacy Arq completed numerous equity offerings that resulted in ownership changes. We have not completed a formal IRC Section 382 analysis of Legacy Arq equity changes from its inception through the Acquisition Date, however, we believe that one or more "ownership changes" occurred during this time period as defined under Sections 382 and 383 and that a portion or all the Legacy Arq Tax Assets may subject to an annual limitation.

31

Non-GAAP Financial Measures

To supplement our financial information presented in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"), we provide certain supplemental financial measures, including EBITDA and Adjusted EBITDA, which are measurements that are not calculated in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). EBITDA is defined as earnings before interest, taxes, depreciation and amortization, and Adjusted EBITDA is defined as EBITDA reduced by the non-cash impact of equity earnings from equity method investments and gain on sale of the Marshall Mine, increased by cash distributions from equity method investments, loss on early settlement of a long-term receivable and loss on change in estimate, asset retirement obligations. EBITDA and Adjusted EBITDA should be considered in addition to, and not as a substitute for, net income in accordance with GAAP as a measure of performance. See below for a reconciliation from Net income, the nearest GAAP financial measure, to EBITDA and Adjusted EBITDA.

We believe that the EBITDA and Adjusted EBITDA measures are less susceptible to variances that affect the Company's operating performance. We include these non-GAAP measures because management uses them in the evaluation of our operating performance, and believe they help to facilitate comparison of operating results between periods. We believe the non-GAAP measures provide useful information to both management and users of the financial statements by excluding certain expenses, gains, and losses which can vary widely across different industries or among companies within the same industry and may not be indicative of core operating results and business outlook.

32

EBITDA and Adjusted EBITDA

The following table reconciles net loss, our most directly comparable as-reported financial measure calculated in accordance with GAAP to EBITDA, (EBITDA Loss), (Adjusted EBITDA Loss) and Adjusted EBITDA.

Additionally, for the year ended December 31, 2023, Net loss included $4.9 million of Legacy Arq payroll and benefit costs and $1.7 million of severance expense related to three executive employees.

Liquidity and Capital Resources

Current Resources and Factors Affecting Our Liquidity

As of December 31, 2023, our principal future sources of liquidity included:

•cash on hand, excluding restricted cash of $8.8 million primarily pledged as collateral under a surety bond agreement; and

•our operations

For the year ended December 31, 2023, our principal uses of liquidity included:

•our business operating expenses;

•capital and spare parts expenditures;

•payments on our lease obligations;

•payments for reclamation associated with the Five Forks Mine; and

•payment required under the sale of Marshall Mine, LLC.

On February 1, 2023, in connection with the Arq Acquisition, we closed the PIPE Investment for an aggregate purchase price of $15.4 million. Further, on February 1, 2023 we entered into the CFG Loan Agreement for $10.0 million, of which we received $8.5 million net proceeds.

Distributions from equity method investees$1,623$5,933

Cash distributions from Tinuum Group and Tinuum Services for 2023 decreased by $4.3 million compared to 2022 primarily due to Tinuum Group and Tinuum Services ceasing material operations as of December 31, 2021.

Cash Flows

Cash and restricted cash decreased from $76.4 million as of December 31, 2022, to $54.2 million as of December 31, 2023, a decrease of $22.3 million. The following table summarizes our cash flows for the years ended December 31, 2023 and 2022, respectively:

Financing activities22,909(1,679)24,588
Net change in Cash and Restricted Cash$(22,279)$(12,348)$(9,931)

Cash flows from operating activities

Cash flows used in operating activities for the year ended December 31, 2023 was $16.7 million compared to cash flows used in operating activities of $6.1 million for the year ended December 31, 2022. The increase in cash used in operating activities was primarily due to the following: (1) an increase in net loss of $3.3 million year over year; (2) a $2.7 million gain on the sale of the Marshall Mine, LLC; (3) a decrease in Distributions from equity method investees, return on investment of $2.3 million year over year; and (4) a net decrease in working capital of $8.9 million primarily as a result of significant payments made in 2023 on accounts payable and accrued expenses assumed in the Arq Acquisition. Offsetting the net increase in cash flows used in operating activities year over year were (1) an increase in Depreciation, amortization, depletion and accretion of $4.1 million; and (2) a decrease in Earnings from equity method investments of $1.9 million.

Cash flows from investing activities

Cash flows used in investing activities for the year ended December 31, 2023 was $28.5 million compared to cash flows used in investing activities of $4.6 million for the year ended December 31, 2022. The increase was primarily due to an increase in acquisition of property, equipment and intangibles, net, of $18.6 million primarily related to acquisition costs related to the Arq Acquisition, a payment of $2.2 million related to the disposal of Marshall Mine, LLC, increased mine development costs of $2.1 million, and a decrease in distributions from equity earnings in excess of cumulative earnings of $2.0 million. Offsetting the net increase in cash flows used in investing activities year over year was $2.2 million cash acquired as part of the Arq Acquisition.

Cash flows from financing activities

Cash flows provided by (used in) financing activities for the year ended December 31, 2023 increased by $24.6 million compared to the year ended December 31, 2022 primarily due to proceeds from common stock issued of $16.2 million,

34

including $1.0 million of proceeds from common stock issued to related parties, and net proceeds from the issuance of the CFG Loan Agreement of $8.5 million.

Material Cash Requirements

Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations depends upon several factors. These include executing on our contracts and initiatives and increasing our share of the market for APT consumables, including expanding our overall AC business into additional adjacent markets and increasing our gross margin from improving our customer and product mix.

Based on current operating levels, we expect that our cash on hand as of December 31, 2023 will provide sufficient liquidity to fund operations for the next 12 months.

Capital expenditures

We have targeted the end of 2024 for the completion of our Red River Plant expansion that is necessary to commence production of our new GAC products. To meet this target, we will incur substantial capital spend in excess of our originally forecasted amount for additional equipment, labor, and project costs. The Company anticipates financing the timely completion of the project funded with cash on hand, cash generation, ongoing cost reduction initiatives, potential customer prepayments for GAC contracts, and a planned refinancing and potential expansion of our term loan. If we are not able to secure additional financing, the project timeline for our Red River Plant expansion may be delayed beyond the end of 2024.

During 2024, we expect to spend between $45 and $50 million on the Red River Plant expansion, depending on the pace of the project, as well as between $5 and $10 million to complete our commissioning of the Corbin Facility. Capital expenditures planned for 2024 are dependent on many factors, including the ability to raise additional funding and approval of certain environmental permits, both of which may impact the timing and amount of capital expenditures.

Surety Bonds

As of December 31, 2023, we had outstanding surety bonds with regulatory commissions totaling $11.2 million primarily related to the Five Forks Mine and the Corbin Facility. As of December 31, 2023, and as required by our surety bond provider, we held restricted cash of $8.5 million pledged as collateral related to performance requirements required under a reclamation contract for the Five Forks Mine and the Corbin Facility. We expect that the obligations secured by these surety bonds will be performed in the ordinary course of business and in accordance with the applicable contractual terms. To the extent that the obligations are performed, the related surety bonds may be released and collateral requirements may be reduced. However, in the event any surety bond is called, our indemnity obligations could require us to reimburse the surety bond provider.

Long Term Requirements

For a discussion of our long-term cash requirements, see Item 8. Note 6 of this Report.

Contractual Obligations

Contractual obligations as of December 31, 2023 are as follows:

Payment Due by Period
(in thousands)TotalLess than 1 year1-3 years4-5 yearsAfter 5 years
CFG Loan$12,199$$$12,199$

$47,837$6,523$9,274$17,099$14,941

The table above excludes our asset retirement obligation ("ARO") related to reclamation of the Five Forks Mine, as the timing and amount of payments to satisfy the ARO are uncertain and are based on numerous factors including, but not limited to, the expected closure date of the Five Forks Mine. As of December 31, 2023, our Consolidated Balance Sheet reflects a liability for AROs of $6.2 million. Additionally, the table above excludes construction costs related to the Red River Plant expansion and Corbin Facility commissioning referred to under "Capital Expenditures" caption above, as the timing and amount of payments

35

to satisfy these obligations are conditional and based on numerous factors including, but not limited to, the pace of construction activities and the timing of mechanical completion of the Red River Plant expansion and commissioning activities at the Corbin Facility.

Critical Accounting Policies and Estimates

Our significant accounting policies are discussed in Note 1 to the Consolidated Financial Statements included in Item 8 of this Report. In presenting our financial statements in conformity with GAAP, we are required to make estimates and assumptions that affect the amounts reported therein. Several of the estimates and assumptions we are required to make relate to matters that are inherently uncertain as they pertain to future events. Our estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions.

We believe that the accounting estimates discussed below are critical to understanding our historical and future performance, as these estimates relate to the more significant areas involving management’s judgments and estimates.

Business Combinations, including asset acquisitions

We apply the acquisition method to acquisitions of both businesses and assets and allocate the purchase price to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The purchase price allocation process requires us to make significant estimates and assumptions with respect to assets acquired and liabilities assumed. We believe the assumptions and estimates we make are reasonable, they are based in part on historical experience, market conditions and information obtained from management of the acquired company or group of assets and are inherently uncertain.

Examples of critical estimates in valuing certain of long-lived assets, including intangible assets, we have acquired or may acquire in the future include but are not limited to:

•future expected cash flows from revenue;

•the acquired company’s developed technology as well as assumptions about the period of time the acquired developed technology will continue to be used in the combined company's product portfolio;

•the expected use and useful lives of the acquired assets; and

•valuation methods and discount rates used in estimating the values of the assets acquired and liabilities assumed.

Carrying value of long-lived assets and intangibles

We review and evaluate our long-lived assets and intangibles for impairment at least annually, or more frequently when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. An impairment loss is measured and recorded for long-lived assets and intangibles based on the excess of their carrying amounts over their estimated fair values. Fair value is typically determined through the use of an income approach utilizing estimates of discounted pretax future cash flows or a market approach utilizing recent transaction activity for comparable assets.

Asset Retirement Obligations

Accounting for AROs requires us to make estimates of future costs unique to a specific mining operation that we will incur to complete the reclamation and remediation work required to comply with existing laws and regulations. Any such changes in future costs, the timing of reclamation activities, scope or the exclusion of certain costs not considered reclamation and remediation costs could materially impact the amounts charged to earnings for reclamation and remediation. Additionally, future changes to environmental laws and regulations could increase the scope of reclamation and remediation work required.

Reclamation costs related to AROs are allocated to expense over the life of the related mine assets and are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. Remediation costs are accrued based on management’s best estimate of the costs expected to be incurred. Such cost estimates may include ongoing care, maintenance and monitoring costs. Reclamation obligations are based on the timing of estimated spending for an existing environmental disturbance. We review, on at least an annual basis, the future expected costs and the timing of such costs for AROs.

Income Taxes

We account for income taxes under the asset and liability method, which requires judgment in determining income tax expense and the related balance sheet amounts. This includes estimating and analyzing historical and projected future operating results, the reversal of taxable temporary differences, tax planning strategies, and the ultimate outcome of uncertain income tax positions. Actual income taxes paid may vary from estimates depending on changes in income tax laws, actual results of operations, state apportionment and, if applicable, final audits of tax returns by taxing authorities. Tax assessments may arise several years after tax returns have been filed. Changes in the estimates and assumptions used for calculating income tax expense and potential differences in actual results from estimates could have a material impact on our results of operations and financial condition.

We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations.

We establish a valuation allowance against our deferred tax assets when, based upon the weight of all available evidence, we believe it is more likely than not that some portion or all of the deferred tax assets will not be realized. In making this determination, we consider the relative impact of all of the available positive and negative evidence regarding future sources of taxable income and tax planning strategies. However, there could be a material impact to our effective tax rate if there is a significant change in our estimates of future taxable income. If and when our estimates change, or there is a change in the value of deferred tax assets or liabilities warranting the need to reassess the realizability of deferred tax assets, we adjust a valuation allowance through the provision for income taxes in the period in which this determination is made. Refer to Note 13 of our Consolidated Financial Statements included in Item 8 of this Report for additional information regarding our deferred tax assets and liabilities.
