NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. GENERAL

Basis of Presentation

The accompanying unaudited consolidated financial statements include the results of operations, financial position and cash flows of US Ecology, Inc. and its wholly-owned subsidiaries. All inter-company balances have been eliminated. Throughout these financial statements words such as “we,” “us,” “our,” “US Ecology” and “the Company” refer to US Ecology, Inc. and its subsidiaries.

In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to present fairly, in all material respects, the results of the Company for the periods presented. These consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted pursuant to the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017. The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the entire year ending December 31, 2018.

The Company’s consolidated balance sheet as of December 31, 2017 has been derived from the Company’s audited consolidated balance sheet as of that date.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our consolidated financial statements. As it relates to estimates and assumptions in amortization rates and environmental obligations, significant engineering, operations and accounting judgments are required. We review these estimates and assumptions no less than annually. In many circumstances, the ultimate outcome of these estimates and assumptions will not be known for decades into the future. Actual results could differ materially from these estimates and assumptions due to changes in applicable regulations, changes in future operational plans and inherent imprecision associated with estimating environmental impacts far into the future.

Recently Issued Accounting Pronouncements

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220). This ASU allows for an optional one-time reclassification from accumulated other comprehensive income (loss) to retained earnings for the stranded tax effects resulting from the new corporate tax rate under the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The new guidance requires additional disclosures, regardless of whether the optional reclassification is elected. This ASU is effective for fiscal years and interim periods beginning after December 15, 2018, with early adoption permitted, and may be applied retrospectively or as of the beginning of the period of adoption. The Company has elected not to make this optional reclassification.

On December 22, 2017, the Tax Act was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system,

Table of Contents

and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under Accounting Standards Codification (“ASC”) 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. Where the Company was able to make reasonable estimates of the effects of elements for which the analysis is not yet complete, the Company has recorded provisional amounts. We were able to reasonably estimate the transition tax and record an initial provisional tax obligation of $1.4 million at December 31, 2017. Adjusted for information available and guidance provided through September 30, 2018, we have now recorded a provisional transition tax obligation totaling $3.3 million. We will continue to consider new guidance related to our provisional amounts and will complete our accounting during the fourth quarter of 2018.

The Tax Act also includes provisions to tax Global Intangible Low-Taxed Income (“GILTI”) of foreign subsidiaries in excess of a deemed return on their tangible assets. Due to the complexities of the new provisions, the Company is continuing to evaluate how the provisions will be accounted for under U.S. GAAP. Pursuant to the Tax Act, corporations are allowed to make an accounting policy election to either (1) account for GILTI as a component of income tax expense in the period in which the corporation is subject to the rules (the “period cost method”), or (2) account for GILTI in the corporation's measurement of deferred taxes (the “deferred method”). The Company has not currently elected a method and will do so after completing its analysis of the GILTI provisions of the Tax Act depending on the analysis of the Company’s global income. Therefore, the Company has not recorded any potential deferred tax effects related to the GILTI in its financial statements and has no policy election regarding whether to record deferred taxes on GILTI or use the period cost method. The Company has, however, included an estimate of the current GILTI impact in its annual effective tax rate for 2018. The Company expects to complete the accounting during the measurement period.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815). This ASU amends the guidance in ASC 815 to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The guidance is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact ASU 2017-12 will have on its consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash (Topic 230). This ASU amends the guidance in ASC 230 to add or clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. ASU 2016-18 is based on the Emerging Issues Task Force’s consensuses reached on Issue 16-A. The guidance is effective for annual and interim periods beginning after December 15, 2017. The Company adopted ASU 2016-18 as of January 1, 2018 using the retrospective adoption method. The impact of retrospective application of ASU 2016-18 is not material, as restricted cash activity for the nine months ended September 30, 2017 was not deemed to be significant. Restricted cash is now included with Cash and cash equivalents when reconciling the beginning-of-period and end-of-period amounts presented in the Company’s consolidated statements of cash flows.

In August 2016, the FASB issued ASU No. 2016-15, Statements of Cash Flows (Topic 230). This ASU amends the guidance in ASC 230 on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of the ASU is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic. The guidance is effective for annual and interim periods beginning after December 15, 2017. The Company adopted ASU 2016-15 as of January 1, 2018 using the retrospective adoption method. The only provision applicable to the Company relates to the treatment of proceeds from the settlement of insurance claims in connection with damaged property and equipment. There was no related impact on the classification of insurance settlement proceeds in the Company’s consolidated statements of cash flows for the nine months ended September 30, 2018 and 2017.

Table of Contents

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The ASU significantly changes the accounting model used by lessees to account for leases, requiring that all material leases be presented on the balance sheet. Lessees will recognize substantially all leases on the balance sheet as a right-of-use asset and a corresponding lease liability. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. The guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11 which provides a practical expedient that allows companies to use an optional transition method. Under the optional transition method, a cumulative adjustment to retained earnings during the period of adoption is recorded and prior periods would not require restatement. The Company plans to elect and use this optional transitional method. We are currently assessing the impact the adoption of ASU 2016-02 may have on our consolidated financial position. We do not expect the adoption of the standards to have a material impact on our results of operations or cash flows and plan to adopt this guidance effective January 1, 2019.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides guidance for revenue recognition. The ASU’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company adopted Topic 606 as of January 1, 2018 using the modified retrospective transition method. See Note 2 for additional information.

NOTE 2. REVENUES

Adoption of ASC Topic 606, “Revenue from Contracts with Customers”

As of January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Revenue Recognition (Topic 605).

Adoption of the guidance did not materially affect the timing or amount of revenue recognized, and no cumulative effect adjustment was recognized as a result of initially applying Topic 606.

Revenue Recognition

Revenues are recognized when control of the promised services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services.

We recognize revenue from three primary sources: 1) waste treatment, recycling and disposal services, 2) field and industrial waste management services, and 3) waste transportation services.

Our waste treatment and disposal customers are legally obligated to properly treat and dispose of their waste in accordance with local, state, and federal laws and regulations. As our customers do not possess the resources to properly treat and dispose of their waste independently, they contract with the Company to perform the services. Waste treatment, recycling, and disposal revenue results primarily from fixed fees charged to customers for treatment and/or disposal or recycling of specified wastes. Waste treatment, recycling, and disposal revenue is generally charged on a per-ton or per-yard basis based on contracted prices and is recognized over time as the services are performed. Our treatment and disposal services are generally performed as the waste is received and considered complete upon final disposal.

Field and industrial waste management services revenue results primarily from specialty onsite services such as high-pressure cleaning, tank cleaning, decontamination, remediation, transportation, spill cleanup and emergency response at refineries, chemical plants, steel and automotive plants, and other government, commercial and industrial facilities. We also provide hazardous waste packaging and collection services and total waste management solutions at customer sites and through our 10-day transfer facilities. These services are provided based on purchase orders or agreements with the customer and include prices based upon daily, hourly or job rates for equipment, materials and personnel. Generally, the

Table of Contents

pricing in these types of contracts is fixed, but the quantity of services to be provided during the contract term is variable and revenues are recognized over the term of the agreements or as services are performed. As we have a right to consideration from our customers in an amount that corresponds directly with the value to the customer of the Company’s performance completed to date, we have applied the practical expedient to recognize revenue in the amount to which we have the right to invoice. Revenue is recognized on contracts with retainage when services have been performed and it is probable that a significant reversal in the amount of cumulative revenue recognized on the contracts will not occur.

Transportation and logistics revenue results from delivering customer waste to a disposal facility for treatment and/or disposal or recycling. Transportation services are generally not provided on a stand-alone basis and instead are bundled with other Company services. However, in some instances we provide transportation and logistics services for shipment of waste from cleanup sites to disposal facilities operated by other companies. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the prices charged to customer or using expected cost plus margin. Transportation revenue is recognized over time as the waste is transported.

Taxes and fees collected from customers concurrent with revenue-producing transactions to be remitted to governmental authorities are excluded from revenue.

Our operations are managed in two reportable segments, Environmental Services and Field & Industrial Services, reflecting our internal reporting structure and nature of services offered. The operations not managed through our two reportable segments are recorded as Corporate. See Note 16 for additional information.

We categorize our treatment and disposal revenue as either “Base Business” or “Event Business” based on the underlying nature of the revenue source. We define Event Business as non-recurring projects that are expected to equal or exceed 1,000 tons, with Base Business defined as all other business not meeting the definition of Event Business. For the three months ended September 30, 2018 and 2017, 22% and 26%, respectively, of our treatment and disposal revenue was derived from Event Business projects. Base Business revenue accounted for 78% and 74% of our treatment and disposal revenue for the three months ended September 30, 2018 and 2017, respectively. For the nine months ended September 30, 2018 and 2017, 20% and 22%, respectively, of our treatment and disposal revenue was derived from Event Business projects. Base Business revenue accounted for 80% and 78% of our treatment and disposal revenue for the nine months ended September 30, 2018 and 2017, respectively.

Deferred Revenue

We record deferred revenue when cash payments are received, or advance billings are charged, prior to performance of services. Deferred revenue includes waste that has been received but not yet treated or disposed, and is recognized when services are performed. During the three and nine months ended September 30, 2018, we recognized $496,000 and $8.3 million of revenue, respectively, that was included in the deferred revenue balance at the beginning of the year.

Receivables

Our receivables include invoiced and unbilled amounts where the Company has an unconditional right to payment.

Principal versus Agent Considerations

The Company commonly contracts with third-parties to perform certain waste-related services that we have promised in our customer contracts. We consider ourselves the principal in these arrangements as we direct the timing, nature and pricing of the services ultimately provided by the third-party to the customer.

Costs to obtain a contract

The Company pays sales commissions to employees, which qualify as costs to obtain a contract. Sales commissions are expensed as incurred as the commissions are earned by the employee and paid by the Company over time as the related revenue is recognized.

Practical Expedients and Optional Exemptions

Our payment terms may vary based on type of service or customer; however, we do not adjust the promised amount of consideration in our contracts for the time value of money as payment terms extended to our customers do not exceed one year and are not considered a significant financing component in our contracts.

We do not disclose the value of unsatisfied performance obligations as contracts with an original expected length of more than one year and contracts for which we do not recognize revenue at the amount to which we have the right to invoice for services performed is insignificant and the aggregate amount of fixed consideration allocated to unsatisfied performance obligations is not material.

NOTE 3. BUSINESS COMBINATION

On August 31, 2018, the Company acquired ES&H of Dallas, LLC (“ES&H Dallas”), which provides emergency and spill response, light industrial services and transportation and logistics for waste disposal and recycling from locations in Dallas and Midland, Texas. The total purchase price was $21.3 million and was funded with cash on hand. The ES&H Dallas facilities are reported as part of our Field and Industrial Services segment. The Company believes that revenues, net income, earnings per share and total assets of ES&H Dallas are not significant and thus, pro forma financial information has not been provided.

We allocated the purchase price to the assets acquired based on preliminary estimates of the fair value at the date of acquisition, resulting in $8.5 million allocated to property and equipment and other current assets, $8.9 million allocated to goodwill (which is deductible for tax purposes) and $3.9 million allocated to intangible assets (consisting primarily of customer relationships) to be amortized over a weighted average life of approximately 14 years. The purchase price allocation is preliminary, as estimates and assumptions are subject to change as more information becomes available.

NOTE 4. ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

Changes in accumulated other comprehensive income (loss) (“AOCI”) consisted of the following:


	Foreign		Unrealized Gain

(1)

Before-tax reclassifications of $40,000 ($31,000 after-tax) and $432,000 ($341,000 after-tax) for the three and nine months ended September 30, 2018, respectively, and before-tax reclassifications of $474,000 ($308,000 after-tax) and $1.8 million ($1.2 a million after-tax) for the three and nine months ended September 30, 2017, were included in Interest expense in the Company’s consolidated statements of operations. Amounts relate to the Company’s interest rate swap which is designated as a cash flow hedge. Changes in fair value of the swap recognized in AOCI are reclassified to interest expense when hedged interest payments on the underlying long-term debt are made. Amounts in AOCI expected to be recognized in interest expense over the next 12 months total approximately $159,000 ($126,000 after-tax).

NOTE 5. CONCENTRATIONS AND CREDIT RISK

Major Customers

No customer accounted for more than 10% of total revenue for the three or nine months ended September 30, 2018 or the three or nine months ended September 30, 2017. No customer accounted for more than 10% of total trade receivables as of September 30, 2018 or December 31, 2017.

Credit Risk Concentration

We maintain most of our cash and cash equivalents with nationally recognized financial institutions. Substantially all balances are uninsured and are not used as collateral for other obligations. Concentrations of credit risk on accounts receivable are believed to be limited due to the number, diversification and character of the obligors and our credit evaluation process.

NOTE 7. FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities recorded at fair value are categorized using defined hierarchical levels directly related to the amount of subjectivity associated with the inputs to fair value measurements, as follows:

Level 1 - Quoted prices in active markets for identical assets or liabilities;

Level 2 - Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable;

Level 3 - Unobservable inputs in which little or no market activity exists, requiring an entity to develop its own assumptions that market participants would use to value the asset or liability.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, restricted cash and investments, accounts payable, accrued liabilities, debt and interest rate swap agreements. The estimated fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their carrying value due to the short-term nature of these instruments.

The Company estimates the fair value of its variable-rate debt using Level 2 inputs, such as interest rates, related terms and maturities of similar obligations. At September 30, 2018, the carrying value of the Company’s variable-rate debt approximates fair value due to the short-term nature of the interest rates.

The Company’s assets and liabilities measured at fair value on a recurring basis consisted of the following:

(1)

We invest a portion of our Restricted cash and investments in fixed-income securities, including U.S. Treasury and U.S. agency securities. We measure the fair value of U.S. Treasury securities using quoted prices for identical assets in active markets. We measure the fair value of U.S. agency securities using observable market activity for similar assets. The fair value of our fixed-income securities approximates our cost basis in the investments.

(2)

We invest a portion of our Restricted cash and investments in money market funds. We measure the fair value of these money market fund investments using quoted prices for identical assets in active markets. Money market funds are considered restricted cash for purposes of reconciling the beginning-of-period and end-of-period amounts presented in the Company’s consolidated statements of cash flows.

(3)

In order to manage interest rate exposure, we entered into an interest rate swap agreement in October 2014 that effectively converts a portion of our variable-rate debt to a fixed interest rate. The swap is designated as a cash flow hedge, with gains and losses deferred in other comprehensive income to be recognized as an adjustment to interest expense in the same period that the hedged interest payments affect earnings. The interest rate swap has an effective date of December 31, 2014 with an initial notional amount of $250.0 million. The fair value of the interest rate swap agreement represents the difference in the present value of cash flows calculated at the contracted interest rates and at current market interest rates at the end of the period. We calculate the fair value of the interest rate swap agreement quarterly based on the quoted market price for the same or similar financial instruments. The fair value of the interest rate swap agreement is included in Other assets and Other long-term liabilities in the Company’s consolidated balance sheet as of September 30, 2018 and December 31, 2017, respectively.

$s in thousands	Gross		Impairment		Gross		Impairment		Total

Balance at September 30, 2018	$	150,193	$	(6,870)	$	53,056	$	—	$	196,379

We assess goodwill for impairment during the fourth quarter as of October 1 of each year, and also if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

In connection with our annual budgeting process commencing in the third quarter and review of the projected future cash flows of our reporting units used in our annual assessment of goodwill, it was determined that the projected future cash flows of our Mobile Recycling reporting unit (described below), which is part of our Environmental Services segment, indicated that the fair value of the reporting unit may be below its carrying amount. Accordingly, we performed an interim assessment of the reporting unit’s goodwill as of September 30, 2018. Based on the results of that assessment, goodwill was deemed impaired and we recognized an impairment charge of $1.4 million in the third quarter of 2018, representing the reporting unit’s entire goodwill balance.

Our Mobile Recycling reporting unit operates a fleet of mobile solvent recycling stills that provide on-site recycling services throughout the Eastern United States. The trailer mounted stills are self-contained units that perform solvent distillation at the point of generation. Waste solvents are processed in 500 to 7,500 gallon batches, and clean solvent is returned for reuse. The factors contributing to the $1.4 million goodwill impairment charge principally related to declining business and cash flows, which negatively impacted the reporting unit’s prospective financial information in its discounted cash flow model and the reporting unit's estimated fair value as compared to previous estimates.

In connection with the interim goodwill impairment assessment of the Mobile Recycling reporting unit, we also assessed the reporting unit’s indefinite-lived permit intangible asset and other finite-lived tangible and intangible assets for impairment as of September 30, 2018. Based on the results of that assessment, the carrying amounts of the indefinite-lived permit intangible asset and other finite-lived intangible assets exceeded their estimated fair values and, as a result, we recognized a $2.3 million impairment charge in the third quarter of 2018. The factors and timing contributing to the indefinite-lived intangible asset and the other finite-lived intangible assets impairment charges were the same as the factors and timing described above with regards to the Mobile Recycling reporting unit goodwill impairment charge.

During the nine months ended September 30, 2018, the Company acquired ES&H Dallas and recorded $8.9 million of goodwill and $3.9 million of amortizing intangible assets (consisting primarily of customer relationships) as a result of the acquisition. See Note 3 for additional information.

Amortization expense was $2.3 million for each of the three months ended September 30, 2018 and 2017. Amortization expense for the nine months ended September 30, 2018 and 2017 was $6.9 million and $7.6 million, respectively. Foreign intangible asset carrying amounts are affected by foreign currency translation.

Credit Agreement

On April 18, 2017, the Company entered into a senior secured credit agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent for the lenders, swingline lender and issuing lender, and Bank of America, N.A., as an issuing lender, that provides for a $500.0 million, five-year revolving credit facility (the “Revolving Credit Facility”), including a $75.0 million sublimit for the issuance of standby letters of credit and a $25.0 million sublimit for the issuance of swingline loans used to fund short-term working capital requirements. The

Table of Contents

Credit Agreement also contains an accordion feature whereby the Company may request up to $200.0 million of additional funds through an increase to the Revolving Credit Facility, through incremental term loans, or some combination thereof.

The Revolving Credit Facility provides up to $500.0 million of revolving credit loans or letters of credit with the use of proceeds restricted solely for working capital and other general corporate purposes (including acquisitions and capital expenditures). Under the Revolving Credit Facility, revolving credit loans are available based on a base rate (as defined in the Credit Agreement) or LIBOR, at the Company’s option, plus an applicable margin which is determined according to a pricing grid under which the interest rate decreases or increases based on our ratio of funded debt to consolidated earnings before interest, taxes, depreciation and amortization (as defined in the Credit Agreement), as set forth in the table below:

Total Net Leverage Ratio	LIBOR Rate Loans Interest Margin	Base Rate Loans Interest Margin
Equal to or greater than 3.25 to 1.00	2.00%	1.00%
Equal to or greater than 2.50 to 1.00, but less than 3.25 to 1.00	1.75%	0.75%
Equal to or greater than 1.75 to 1.00, but less than 2.50 to 1.00	1.50%	0.50%
Equal to or greater than 1.00 to 1.00, but less than 1.75 to 1.00	1.25%	0.25%
Less than 1.00 to 1.00	1.00%	0.00%

At September 30, 2018, the effective interest rate on the Revolving Credit Facility, after giving effect to the impact of our interest rate swap, was 3.49%. Interest only payments are due either quarterly or on the last day of any interest period, as applicable.

In October 2014, the Company entered into an interest rate swap agreement, effectively fixing the interest rate on $175.0 million, or 63%, of the Revolving Credit Facility borrowings as of September 30, 2018.

The Company is required to pay a commitment fee ranging from 0.175% to 0.35% on the average daily unused portion of the Revolving Credit Facility, with such commitment fee to be reduced based upon the Company’s total net leverage ratio (as defined in the Credit Agreement). The maximum letter of credit capacity under the Revolving Credit Facility is $75.0 million and the Credit Agreement provides for a letter of credit fee equal to the applicable margin for LIBOR loans under the Revolving Credit Facility. At September 30, 2018, there were $277.0 million of revolving credit loans outstanding on the Revolving Credit Facility. These revolving credit loans are due upon the earliest to occur of (a) April 18, 2022 (or, with respect to any lender, such later date as requested by us and accepted by such lender), (b) the date of termination of the entire revolving credit commitment (as defined in the Credit Agreement) by us, and (c) the date of termination of the revolving credit commitment and are presented as long-term debt in the consolidated balance sheets.

The Company has entered into a sweep arrangement whereby day-to-day cash requirements in excess of available cash balances are advanced to the Company on an as-needed basis with repayments of these advances automatically made from subsequent deposits to our cash operating accounts (the “Sweep Arrangement”). Total advances outstanding under the Sweep Arrangement are subject to the $25.0 million swingline loan sublimit under the Revolving Credit Facility. The Company’s revolving credit loans outstanding under the Revolving Credit Agreement are not subject to repayment through the Sweep Arrangement. As of September 30, 2018, there were no amounts outstanding subject to the Sweep Arrangement.

As of September 30, 2018, the availability under the Revolving Credit Facility was $217.3 million with $5.7 million of the Revolving Credit Facility issued in the form of standby letters of credit utilized as collateral for closure and post-closure financial assurance and other assurance obligations.

The Company may at any time and from time to time prepay revolving credit loans and swingline loans, in whole or in part, without premium or penalty, subject to the obligation to indemnify each of the lenders against any actual loss or expense (including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain a LIBOR rate loan (as defined in the Credit Agreement) or from fees payable to terminate the deposits from which such funds were obtained) with respect to the early termination of any LIBOR rate loan. The Credit Agreement provides for mandatory prepayment at any time if the revolving credit outstanding exceeds the revolving credit commitment (as such terms are defined in the Credit Agreement), in an amount equal to such excess. Subject to certain exceptions, the Credit

Table of Contents

Agreement provides for mandatory prepayment upon certain asset dispositions, casualty events and issuances of indebtedness.

Pursuant to (i) an unconditional guarantee agreement and (ii) a collateral agreement, each entered into by the Company and its domestic subsidiaries on April 18, 2017, the Company’s obligations under the Credit Agreement are (or will be) jointly and severally and fully and unconditionally guaranteed on a senior basis by all of the Company’s existing and certain future domestic subsidiaries and are secured by substantially all of the assets of the Company and the Company’s existing and certain future domestic subsidiaries (subject to certain exclusions), including 100% of the equity interests of the Company’s domestic subsidiaries and 65% of the voting equity interests of the Company’s directly owned foreign subsidiaries (and 100% of the non-voting equity interests of the Company’s directly owned foreign subsidiaries).

The Credit Agreement contains customary restrictive covenants, subject to certain permitted amounts and exceptions, including covenants limiting the ability of the Company to incur additional indebtedness, pay dividends and make other restricted payments, repurchase shares of our outstanding stock and create certain liens. Upon the occurrence of an event of default (as defined in the Credit Agreement), among other things, amounts outstanding under the Credit Agreement may be accelerated and the commitments may be terminated.

The Credit Agreement also contains financial maintenance covenants, a maximum consolidated total net leverage ratio and a consolidated interest coverage ratio (as such terms are defined in the Credit Agreement). Our consolidated total net leverage ratio as of the last day of any fiscal quarter, commencing with the fiscal quarter ending June 30, 2017, may not exceed 3.50 to 1.00, subject to certain exceptions. Our consolidated interest coverage ratio as of the last day of any fiscal quarter, commencing with the fiscal quarter ending June 30, 2017, may not be less than 3.00 to 1.00.

At September 30, 2018, we were in compliance with all of the financial covenants in the Credit Agreement.

NOTE 11. CLOSURE AND POST-CLOSURE OBLIGATIONS

Our accrued closure and post-closure liability represents the expected future costs, including corrective actions, associated with closure and post-closure of our operating and non-operating disposal facilities. We record the fair value of our closure and post-closure obligations as a liability in the period in which the regulatory obligation to retire a specific asset is triggered. For our individual landfill cells, the required closure and post-closure obligations under the terms of our permits and our intended operation of the landfill cell are triggered and recorded when the cell is placed into service and waste is initially disposed in the landfill cell. The fair value is based on the total estimated costs to close the landfill cell and perform post-closure activities once the landfill cell has reached capacity and is no longer accepting waste. We perform periodic reviews of both non-operating and operating facilities and revise accruals for estimated closure and post-closure, remediation or other costs as necessary. Recorded liabilities are based on our best estimates of current costs and are updated periodically to include the effects of existing technology, presently enacted laws and regulations, inflation and other economic factors.

NOTE 12. INCOME TAXES

Our effective tax rate for the three months ended September 30, 2018 was 20.2%, down from 35.8% for the three months ended September 30, 2017. Our effective tax rate for the nine months ended September 30, 2018 was 23.7%, down from 36.0% for the nine months ended September 30, 2017. The decrease for the three and nine months ended September 30, 2018 compared with the three and nine months ended September 30, 2017 was primarily the result of the impact of the Tax Act, enacted on December 22, 2017 by the U.S. government which reduced the federal corporate tax rate to 21% from the existing maximum rate of 35%. In addition, the Company implemented various federal and state tax planning strategies which favorably impacted the effective tax rate, partially offset by the impact of the tax associated with the deemed repatriation of foreign earnings. The decrease in the effective tax rate for the three and nine months ended September 30, 2018 also reflects the impact of discrete events including the recognition of excess tax benefits related to employee stock compensation as a result of the adoption of ASU 2016-09, Compensation - Stock Compensation (Topic 718), on January 1, 2017.

On December 22, 2017, Staff Accounting Bulletin No. 118 was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. We were able to reasonably estimate the transition tax and record an initial provisional tax obligation of $1.4 million at December 31, 2017. As adjusted for new information available and guidance provided through September 30, 2018, we have now recorded a provisional transition tax obligation totaling $3.3 million. We will continue to consider new guidance related to our provisional amounts and will complete our accounting during the fourth quarter of 2018.

Gross unrecognized tax benefits were $590,000 as of September 30, 2018 that, if recognized, would favorably affect our effective tax rate. Gross unrecognized tax benefits are included in Other long-term liabilities in the consolidated balance sheet as of September 30, 2018. There were no unrecognized tax benefits as of December 31, 2017. We do not anticipate our total unrecognized tax benefits to increase or decrease materially within the next twelve months. We recognize interest assessed by taxing authorities or interest associated with uncertain tax positions as a component of interest expense. We recognize any penalties assessed by taxing authorities or penalties associated with uncertain tax positions as a component of selling, general and administrative expenses.

We file a consolidated U.S. federal income tax return with the Internal Revenue Service (“IRS”) as well as tax returns in various states, Canada, and Mexico. The Company is subject to examination by the IRS for tax years 2014 through 2017. EQ Holdings, Inc. is subject to examination by the IRS for pre-acquisition tax year 2014. We may be subject to examinations by various state and local taxing jurisdictions for tax years 2013 through 2017. The Company is not aware of any significant foreign jurisdiction audits underway. The tax years 2013 through 2017 remain subject to examination by foreign jurisdictions.

NOTE 14. EQUITY

Stock Repurchase Program

On June 1, 2016, the Company’s Board of Directors authorized the repurchase of $25.0 million of the Company’s outstanding common stock. Repurchases may be made from time to time in the open market or through privately negotiated transactions. The timing of any repurchases will be based upon prevailing market conditions and other factors. The Company did not repurchase any shares of common stock under the repurchase program during the three or nine months ended September 30, 2018. On May 29, 2018 the repurchase program was extended and will remain in effect until June 6, 2020, unless further extended by our Board of Directors.

Omnibus Incentive Plan

On May 27, 2015, our stockholders approved the Omnibus Incentive Plan (“Omnibus Plan”), which was approved by our Board of Directors on April 7, 2015. The Omnibus Plan was developed to provide additional incentives through equity ownership in US Ecology and, as a result, encourage employees and directors to contribute to our success. The Omnibus Plan provides, among other things, the ability for the Company to grant restricted stock, performance stock, options, stock appreciation rights, restricted stock units (“RSUs”), performance stock units (“PSUs”) and other stock-based awards or cash awards to officers, employees, consultants and non-employee directors. Subsequent to the approval of the Omnibus Plan in May 2015, we stopped granting equity awards under our 2008 Stock Option Incentive Plan and our 2006 Restricted Stock Plan (collectively, the “Previous Plans”). The Previous Plans will remain in effect solely for the settlement of awards granted under the Previous Plans. No shares that are reserved but unissued under the Previous Plans or that are outstanding under the Previous Plans and reacquired by the Company for any reason will be available for issuance under the Omnibus Plan. The Omnibus Plan expires on April 7, 2025 and authorizes 1,500,000 shares of common stock for grant over the life of the Omnibus Plan. As of September 30, 2018, 1,017,403 shares of common stock remain available for grant under the Omnibus Plan.

PSUs, RSUs and Restricted Stock

On January 2, 2018, the Company granted 14,100 PSUs to certain employees. Each PSU represents the right to receive, on the settlement date, one share of the Company’s common stock. The total number of PSUs each participant is eligible to earn ranges from 0% to 200% of the target number of PSUs granted. The actual number of PSUs that will vest and be settled in shares is determined at the end of a three-year performance period beginning January 1, 2018, based on total stockholder return relative to a set of peer companies. The fair value of the PSUs estimated on the grant date using a Monte Carlo simulation was $63.56 per unit. Compensation expense is recorded over the awards’ vesting period.

NOTE 15. COMMITMENTS AND CONTINGENCIES

Litigation and Regulatory Proceedings

In the ordinary course of business, we are involved in judicial and administrative proceedings involving federal, state, provincial or local governmental authorities, including regulatory agencies that oversee and enforce compliance with permits. Fines or penalties may be assessed by regulators for non-compliance. Actions may also be brought by individuals or groups in connection with permitting of planned facilities, modification or alleged violations of existing permits, or alleged damages suffered from exposure to hazardous substances purportedly released from our operated sites, as well as other litigation. We maintain insurance intended to cover property and damage claims asserted as a result of our operations. Periodically, management reviews and may establish reserves for legal and administrative matters, or other fees expected to be incurred in relation to these matters.

We are not currently a party to any material pending legal proceedings and are not aware of any other claims that could, individually or in the aggregate, have a materially adverse effect on our financial position, results of operations or cash flows.

NOTE 16. OPERATING SEGMENTS

Financial Information by Segment

Our operations are managed in two reportable segments reflecting our internal reporting structure and nature of services offered as follows:

Environmental Services - This segment provides a broad range of hazardous material management services including transportation, recycling, treatment and disposal of hazardous and non-hazardous waste at Company-owned landfill, wastewater and other treatment facilities.

Field & Industrial Services - This segment provides packaging and collection of hazardous waste and total waste management solutions at customer sites and through our 10-day transfer facilities. Services include on-site management, waste characterization, transportation and disposal of non-hazardous and hazardous waste. This segment also provides specialty services such as high-pressure cleaning, tank cleaning, decontamination, remediation, transportation, spill cleanup and emergency response and other services to commercial and industrial facilities and to government entities.

The operations not managed through our two reportable segments are recorded as "Corporate." Corporate selling, general and administrative expenses include typical corporate items such as legal, accounting and other items of a general corporate nature. Income taxes are assigned to Corporate, but all other items are included in the segment where they originated. Inter-company transactions have been eliminated from the segment information and are not significant between segments.

Summarized financial information of our reportable segments is as follows:

Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“Adjusted EBITDA”)

Management uses Adjusted EBITDA as a financial measure to assess segment performance. Adjusted EBITDA is defined as net income before interest expense, interest income, income tax expense, depreciation, amortization, stock-based compensation, accretion of closure and post-closure liabilities, foreign currency gain/loss, non-cash impairment charges and other income/expense. Adjusted EBITDA is a complement to results provided in accordance with GAAP and we believe that such information provides additional useful information to analysts, stockholders and other users to understand the Company’s operating performance. Since Adjusted EBITDA is not a measurement determined in accordance with GAAP and is thus susceptible to varying calculations, Adjusted EBITDA as presented may not be comparable to other similarly titled measures of other companies. Items excluded from Adjusted EBITDA are significant components in understanding and assessing our financial performance. Adjusted EBITDA should not be considered in isolation or as an alternative to, or substitute for, net income, cash flows generated by operations, investing or financing activities, or other financial statement data presented in the consolidated financial statements as indicators of financial performance or liquidity. Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation or a substitute for analyzing our results as reported under GAAP. Some of the limitations are:

Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

Adjusted EBITDA does not reflect our interest expense, or the requirements necessary to service interest or principal payments on our debt;

Adjusted EBITDA does not reflect our income tax expenses or the cash requirements to pay our taxes;

Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments; and

Although depreciation and amortization charges are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of US Ecology, Inc.

Results of Review of Interim Financial Information

We have reviewed the accompanying consolidated balance sheet of US Ecology, Inc. and subsidiaries (the "Company") as of September 30, 2018, the related consolidated statements of operations, comprehensive income, and cash flows for the three-month and nine-month periods ended September 30, 2018 and 2017, and the related notes (collectively referred to as the "interim financial information"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2017, and the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated February 26, 2018, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2017, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information contained in this section should be read in conjunction with our unaudited consolidated financial statements and related notes thereto appearing elsewhere in this quarterly report on Form 10-Q. In this report words such as “we,” “us,” “our,” “US Ecology” and “the Company” refer to US Ecology, Inc. and its subsidiaries.

OVERVIEW

US Ecology, Inc. is a leading North American provider of environmental services to commercial and government entities. The Company addresses the complex waste management needs of its customers, offering treatment, disposal and recycling of hazardous, non-hazardous and radioactive waste, as well as a wide range of complementary field and industrial services. US Ecology’s comprehensive knowledge of the waste business, its collection of waste management facilities and focus on safety, environmental compliance, and customer service enables us to effectively meet the needs of our customers and to build long-lasting relationships.

We have fixed facilities and service centers operating in the United States, Canada and Mexico. Our fixed facilities include five Resource Conservation and Recovery Act of 1976, subtitle C, hazardous waste landfills and one low-level radioactive waste landfill located near Beatty, Nevada; Richland, Washington; Robstown, Texas; Grand View, Idaho; Detroit, Michigan and Blainville, Québec, Canada. These facilities generate revenue from fees charged to treat and dispose of waste and from fees charged to perform various field and industrial services for our customers.

Our operations are managed in two reportable segments reflecting our internal management reporting structure and nature of services offered as follows:

In order to provide insight into the underlying drivers of our waste volumes and related treatment and disposal (“T&D”) revenues, we evaluate period-to-period changes in our T&D revenue for our Environmental Services segment based on the industry of the waste generator, based on North American Industry Classification System (“NAICS”) codes.

Table of Contents

The composition of Environmental Services segment T&D revenues by waste generator industry for the three and nine months ended September 30, 2018 and 2017 were as follows:


	% of Treatment and Disposal Revenue (1) for the
	Three Months Ended September 30,

Mining, Exploration and Production	2%	3%
Other (2)	15%	12%

(1)

Excludes all transportation service revenue

(2)

Includes retail and wholesale trade, rate regulated, construction and other industries

We also categorize our Environmental Services T&D revenue as either “Base Business” or “Event Business” based on the underlying nature of the revenue source.

Base Business consists of waste streams from ongoing industrial activities and tends to be recurring in nature. We define Event Business as non-recurring projects that are expected to equal or exceed 1,000 tons, with Base Business defined as all other business not meeting the definition of Event Business. The duration of Event Business projects can last from a several-week cleanup of a contaminated site to a multiple year cleanup project.

For the three months ended September 30, 2018, Base Business revenue increased 9% compared to the three months ended September 30, 2017. For the three months ended September 30, 2018, approximately 78% of our total T&D revenue was derived from our Base Business, up from 74% for the three months ended September 30, 2017. For the nine months ended September 30, 2018, Base Business revenue increased 8% compared to the nine months ended September 30, 2017. For the nine months ended September 30, 2018, approximately 80% of our total T&D revenue was derived from our Base Business, up from 78% for the nine months ended September 30, 2017. Our business is highly competitive and no assurance can be given that we will maintain these revenue levels or increase our market share.

Table of Contents

A significant portion of our disposal revenue is attributable to discrete Event Business projects which vary widely in size, duration and unit pricing. For the three months ended September 30, 2018, approximately 22% of our total T&D revenue was derived from Event Business projects, down from 26% for the three months ended September 30, 2017. For the three months ended September 30, 2018, Event Business revenue decreased 8% compared to the three months ended September 30, 2017. For the nine months ended September 30, 2018, approximately 20% of our total T&D revenue was derived from Event Business projects, down from 22% for the nine months ended September 30, 2017. For the nine months ended September 30, 2018, Event Business revenue decreased 4% compared to the nine months ended September 30, 2017. The one-time nature of Event Business, diverse spectrum of waste types received and widely varying unit pricing necessarily creates variability in revenue and earnings. This variability may be influenced by general and industry-specific economic conditions, funding availability, changes in laws and regulations, government enforcement actions or court orders, public controversy, litigation, weather, commercial real estate, closed military bases and other project timing, government appropriation and funding cycles and other factors. The types and amounts of waste received from Base Business also vary from quarter to quarter.

This variability can also cause significant quarter-to-quarter and year-to-year differences in revenue, gross profit, gross margin, operating income and net income. While we pursue many projects months or years in advance of work performance, cleanup project opportunities routinely arise with little or no prior notice. These market dynamics are inherent to the waste disposal business and are factored into our projections and externally communicated business outlook statements. Our projections combine historical experience with identified sales pipeline opportunities, new or expanded service line projections and prevailing market conditions.

Depending on project-specific customer needs and competitive economics, transportation services may be offered at or near our cost to help secure new business. For waste transported by rail from the eastern United States and other locations distant from our Grand View, Idaho and Robstown, Texas facilities, transportation-related revenue can account for as much as 75% of total project revenue. While bundling transportation and disposal services reduces overall gross profit as a percentage of total revenue (“gross margin”), this value-added service has allowed us to win multiple projects that management believes we could not have otherwise competed for successfully. Our Company-owned fleet of gondola railcars, which is periodically supplemented with railcars obtained under operating leases, has reduced our transportation expenses by largely eliminating reliance on more costly short-term rentals. These Company-owned railcars also help us to win business during times of demand-driven railcar scarcity.

The increased waste volumes resulting from projects won through this bundled service strategy further drive operating leverage benefits inherent to the disposal business, increasing profitability. While waste treatment and other variable costs are project-specific, the incremental earnings contribution from large and small projects generally increases as overall disposal volumes increase. Based on past experience, management believes that maximizing operating income, net income and earnings per share is a higher priority than maintaining or increasing gross margin. We intend to continue aggressively bidding bundled transportation and disposal services based on this proven strategy.

We serve oil refineries, chemical production plants, steel mills, waste brokers/aggregators serving small manufacturers and other industrial customers that are generally affected by the prevailing economic conditions and credit environment. Adverse conditions may cause our customers as well as those they serve to curtail operations, resulting in lower waste production and/or delayed spending on off-site waste shipments, maintenance, waste cleanup projects and other work. Factors that can impact general economic conditions and the level of spending by customers include, but are not limited to, consumer and industrial spending, increases in fuel and energy costs, conditions in the real estate and mortgage markets, labor and healthcare costs, access to credit, consumer confidence and other global economic factors affecting spending behavior. Market forces may also induce customers to reduce or cease operations, declare bankruptcy, liquidate or relocate to other countries, any of which could adversely affect our business. To the extent business is either government funded or driven by government regulations or enforcement actions, we believe it is less susceptible to general economic conditions. Spending by government agencies may be reduced due to declining tax revenues resulting from a weak economy or changes in policy. Disbursement of funds appropriated by Congress may also be delayed for various reasons.

Components of Adjusted EBITDA

Income tax expense

Our effective income tax rate for the third quarter of 2018 was 20.2%, compared with 35.8% for the third quarter of 2017. The decrease was primarily the result of the impact of the Tax Act, enacted on December 22, 2017 by the U.S. government which reduced the federal corporate tax rate to 21% from the existing maximum rate of 35%. In addition, the Company implemented various federal and state tax planning strategies which favorably impacted the effective tax rate, partially offset by the impact of the tax associated with the deemed repatriation of foreign earnings.

Interest expense

Interest expense was $3.1 million for the third quarter of 2018 compared with $2.8 million for the third quarter of 2017. The increase was primarily the result of higher interest rates on the variable portion of our credit facility in the third quarter of 2018 compared to the third quarter of 2017.

Foreign currency gain (loss)

We recognized a $303,000 non-cash foreign currency loss for the third quarter of 2018 compared with a $275,000 non-cash foreign currency gain for the third quarter of 2017. Foreign currency gains and losses reflect changes in business activity conducted in a currency other than the United States dollar (“USD”), our functional currency. Additionally, we established intercompany loans between our Canadian subsidiaries, whose functional currency is the Canadian dollar (“CAD”), and our parent company, US Ecology, as part of a tax and treasury management strategy allowing for repayment of third-party bank debt. These intercompany loans are payable by our Canadian subsidiaries to US Ecology in CAD requiring us to revalue the outstanding loan balance through our statements of operations based on USD/CAD currency movements from period to period. At September 30, 2018, we had $21.5 million of intercompany loans subject to currency revaluation.

Components of Adjusted EBITDA

Income tax expense

Our effective income tax rate for the first nine months of 2018 was 23.7%, down from 36.0% for the nine months ended September 31, 2017. The decrease was primarily the result of the impact of the Tax Act, enacted on December 22, 2017 by the U.S. government which reduced the federal corporate tax rate to 21% from the existing maximum rate of 35%. In addition, the Company implemented various federal and state tax planning strategies which favorably impacted the effective tax rate, partially offset by the impact of the tax associated with the deemed repatriation of foreign earnings.

Interest expense

Interest expense was $8.8 million for the first nine months of 2018 compared with $15.4 million for the first nine months of 2017. The decrease in interest expense in the first nine months of 2018 was primarily the result of a one-time non-cash charge of $5.5 million to interest expense in 2017 related to the refinancing of our former credit agreement. The remaining decrease is attributable a lower effective interest rate under our new credit agreement.

Foreign currency gain (loss)

We recognized a $456,000 non-cash foreign currency loss for the first nine months of 2018 compared with a $521,000 non-cash foreign currency gain for the first nine months of 2017.

CRITICAL ACCOUNTING POLICIES

Financial statement preparation requires management to make estimates and judgments that affect reported assets, liabilities, revenue and expenses and disclosure of contingent assets and liabilities. The accompanying unaudited consolidated financial statements are prepared using the same critical accounting policies disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017, other than the adoption of the Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, described in Note 2 of the Notes to Consolidated Financial Statements in “Part I, Item 1. Financial Statements (Unaudited)” of this Quarterly Report on Form 10-Q.

RECENTLY ISSUED ACCOUNTING STANDARDS

For information about recently issued accounting standards, see Note 1 of the Notes to Consolidated Financial Statements in “Part I, Item 1. Financial Statements (Unaudited)” of this Quarterly Report on Form 10-Q.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity are cash and cash equivalents, cash generated from operations and borrowings under our senior secured Credit Agreement entered into on April 18, 2017. At September 30, 2018, we had $26.1 million in cash and cash equivalents immediately available and $217.3 million of borrowing capacity available under our Credit Agreement. We assess our liquidity in terms of our ability to generate cash to fund our operating, investing and financing activities. Our primary ongoing cash requirements are funding operations, capital expenditures, paying interest on our long-term debt, and paying declared dividends pursuant to our dividend policy. We believe future operating cash flows will be sufficient to meet our future operating, investing and dividend cash needs for the foreseeable future. Furthermore, existing cash balances and availability of additional borrowings under our Credit Agreement provide additional sources of liquidity should they be required.

Operating Activities

For the nine months ended September 30, 2018, net cash provided by operating activities was $55.5 million. This primarily reflects net income of $35.9 million, non-cash depreciation, amortization and accretion of $31.2 million, an increase in accounts payable and accrued liabilities of $12.8 million, deferred income taxes of $4.7 million, non-cash impairment charges of $3.7 million, and share-based compensation of $3.3 million, partially offset by an increase in accounts receivable of $27.6 million and an increase in income taxes receivable of $7.9 million. Impacts on net income are due to the factors discussed above under “Results of Operations.” The increase in accounts payable and accrued liabilities is primarily attributable to the timing of payments to vendors for products and services. Changes in deferred income taxes and income taxes receivable are primarily attributable to the implementation of various federal and state tax planning strategies, as well as the timing of income tax payments. The increase in receivables is primarily attributable to the timing of customer payments.

Days sales outstanding were 81 days as of September 30, 2018, compared to 77 days as of December 31, 2017 and 79 days as of September 30, 2017.

For the nine months ended September 30, 2017, net cash provided by operating activities was $49.4 million. This primarily reflects net income of $18.6 million, non-cash depreciation, amortization and accretion of $31.8 million, an increase in accounts payable and accrued liabilities of $6.2 million, amortization and write-off of debt issuance costs of $5.8 million, an increase in deferred revenue of $4.2 million, share-based compensation expense of $3.0 million, an increase in accrued salaries and benefits of $2.7 million and a decrease in income taxes receivable of $1.6 million, partially offset by an increase in accounts receivable of $20.1 million and an increase in other assets of $2.6 million. Impacts on net income are due to the factors discussed above under “Results of Operations.” The increase in accounts payable and accrued liabilities is primarily attributable to the timing of payments to vendors for products and services. The increase in deferred revenue is primarily attributable to the timing of the treatment and disposal of waste received but not yet processed. The increase in receivables is primarily attributable to the timing of customer payments. The decrease in income taxes receivable is primarily attributable to the timing of income tax payments.

Investing Activities

For the nine months ended September 30, 2018, net cash used in investing activities was $46.8 million, primarily related to capital expenditures of $25.8 million and the acquisition of ES&H of Dallas, LLC for $21.3 million. Significant capital projects included continuing construction of additional disposal capacity and railway expansion at our Blainville, Quebec, Canada location and equipment purchases and infrastructure upgrades at our corporate and operating facilities.

For the nine months ended September 30, 2017, net cash used in investing activities was $25.4 million, primarily related to capital expenditures. Significant capital projects included construction of additional disposal capacity at our Beatty, Nevada and Blainville, Quebec, Canada locations and equipment purchases and infrastructure upgrades at our corporate and operating facilities.

Financing Activities

For the nine months ended September 30, 2018, net cash used in financing activities was $10.1 million, consisting primarily of dividend payments to our stockholders of $11.8 million, partially offset by $2.4 million in proceeds received from the exercise of stock options.

For the nine months ended September 30, 2017, net cash used in financing activities was $22.3 million, consisting primarily of $283.0 million of repayment of the Company’s long-term debt under our former credit agreement, $281.0 million of initial proceeds from the borrowing of long-term debt under the new credit agreement, $4.0 million of subsequent repayments of long-term debt under the new credit agreement, $11.8 million of dividend payments to our stockholders, $3.0 million of deferred financing costs associated with the new credit agreement and net payment activity on the Company’s short-term borrowings of $2.2 million.

Credit Agreement

The Credit Agreement (the “new credit agreement” or the “Credit Agreement”) provides for a $500.0 million, five-year revolving credit facility (the “Revolving Credit Facility”), including a $75.0 million sublimit for the issuance of standby letters of credit and a $25.0 million sublimit for the issuance of swingline loans used to fund short-term working capital requirements. The Credit Agreement also contains an accordion feature whereby the Company may request up to $200.0 million of additional funds through an increase to the Revolving Credit Facility, through incremental term loans, or some combination thereof. Proceeds from the Revolving Credit Facility are restricted solely for working capital and other general corporate purposes (including acquisitions and capital expenditures). Under the Revolving Credit Facility, revolving credit loans are available based on a base rate (as defined in the Credit Agreement) or LIBOR, at the Company’s option, plus an applicable margin which is determined according to a pricing grid under which the interest rate decreases or increases based on our ratio of funded debt to consolidated earnings before interest, taxes, depreciation and amortization (as defined in the Credit Agreement).

At September 30, 2018, the effective interest rate on the Revolving Credit Facility, including the impact of our interest rate swap, was 3.49%. Interest only payments are due either quarterly or on the last day of any interest period, as applicable. In October 2014, the Company entered into an interest rate swap agreement, effectively fixing the interest rate on $175.0 million, or 63%, of the Revolving Credit Facility borrowings as of September 30, 2018.

The Company is required to pay a commitment fee ranging from 0.175% to 0.35% on the average daily unused portion of the Revolving Credit Facility, with such commitment fee to be reduced based upon the Company’s total net leverage ratio (as defined in the Credit Agreement). The maximum letter of credit capacity under the Revolving Credit Facility is $75.0 million and the Credit Agreement provides for a letter of credit fee equal to the applicable margin for LIBOR loans under the Revolving Credit Facility. At September 30, 2018, there were $277.0 million of borrowings outstanding on the Revolving Credit Facility. These borrowings are due on the revolving credit maturity date (as defined in the Credit Agreement) and presented as long-term debt in the consolidated balance sheets.

subsequent deposits to our cash operating accounts (the “Sweep Arrangement”). Total advances outstanding under the Sweep Arrangement are subject to the $25.0 million swingline loan sublimit under the Revolving Credit Facility. The Company’s revolving credit loans outstanding under the Revolving Credit Agreement are not subject to repayment through the Sweep Arrangement. As of September 30, 2018, there were no amounts outstanding subject to the Sweep Arrangement.

As of September 30, 2018, the availability under the Revolving Credit Facility was $217.3 million with $5.7 million of the Revolving Credit Facility issued in the form of standby letter of credit utilized as collateral for closure and post-closure financial assurance and other assurance obligations.

For more information about our debt, see Note 10 of the Notes to Consolidated Financial Statements in “Part I, Item 1. Financial Statements (Unaudited)” of this Quarterly Report on Form 10-Q.

CONTRACTUAL OBLIGATIONS AND GUARANTEES

There were no material changes in the amounts of our contractual obligations and guarantees during the nine months ended September 30, 2018. For further information on our contractual obligations and guarantees, refer to our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We do not maintain equities, commodities, derivatives, or any other similar instruments for trading purposes. We have minimal interest rate risk on investments or other assets due to our preservation of capital approach to investments. At September 30, 2018, $4.9 million of restricted cash was invested in fixed-income U.S. Treasury and U.S. government agency securities and money market accounts.

We are exposed to changes in interest rates as a result of our borrowings under the Credit Agreement. Under the Credit Agreement, Revolving Credit Facility borrowings incur interest at a base rate (as defined in the Credit Agreement) or LIBOR, at the Company’s option, plus an applicable margin which is determined according to a pricing grid under which the interest rate decreases or increases based on our ratio of funded debt to consolidated earnings before interest, taxes, depreciation and amortization (as defined in the Credit Agreement). On October 29, 2014, the Company entered into an interest rate swap agreement with the intention of hedging the Company’s interest rate exposure on a portion of the Company’s outstanding LIBOR-based variable rate debt. Under the terms of the swap, the Company pays interest at the fixed effective rate of 3.67% and receives interest at the variable one-month LIBOR rate on an initial notional amount of $250.0 million.

As of September 30, 2018, there were $277.0 million of revolving loans outstanding under the Credit Agreement. If interest rates were to rise and outstanding balances remain unchanged, we would be subject to higher interest payments on our outstanding debt. Subsequent to the effective date of the interest rate swap on December 31, 2014, we are subject to higher interest payments on only the unhedged borrowings under the Credit Agreement.

Based on the outstanding indebtedness of $277.0 million under the Credit Agreement at September 30, 2018 and the impact of our interest rate hedge, if market rates used to calculate interest expense were to average 1% higher in the next twelve months, our interest expense would increase by approximately $1.1 million for the corresponding period.

Foreign Currency Risk

We are subject to currency exposures and volatility because of currency fluctuations. The majority of our transactions are in USD; however, our Canadian subsidiaries conduct business in both Canada and the United States. In addition, contracts for services that our Canadian subsidiaries provide to U.S. customers are generally denominated in USD. During the nine months ended September 30, 2018, our Canadian subsidiaries transacted approximately 71% of their revenue in USD and at any time have cash on deposit in USD and outstanding USD trade receivables and payables related to these transactions.

Table of Contents

These USD cash, receivable and payable accounts are subject to non-cash foreign currency translation gains or losses. Exchange rate movements also affect the translation of Canadian generated profits and losses into USD.

We established intercompany loans between our Canadian subsidiaries and our parent company, US Ecology, as part of a tax and treasury management strategy allowing for repayment of third-party bank debt. These intercompany loans are payable using CAD and are subject to mark-to-market adjustments with movements in the CAD. At September 30, 2018, we had $21.5 million of intercompany loans outstanding between our Canadian subsidiaries and US Ecology. During the nine months ended September 30, 2018, the CAD weakened as compared to the USD resulting in a $716,000 non-cash foreign currency translation loss being recognized in the Company’s consolidated statements of operations related to the intercompany loans. Based on intercompany balances as of September 30, 2018, a $0.01 CAD increase or decrease in currency rate compared to the USD at September 30, 2018 would have generated a gain or loss of approximately $215,000 for the nine months ended September 30, 2018.

We had a total pre-tax foreign currency loss of $456,000 for the nine months ended September 30, 2018. We currently have no foreign exchange contracts, option contracts or other foreign currency hedging arrangements. Management evaluates the Company’s risk position on an ongoing basis to determine whether foreign exchange hedging strategies should be employed.

ITEM 4. CONTROLS AND PROCEDURES

Management of the Company, including the Chief Executive Officer and the Chief Financial Officer of the Company, have evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of September 30, 2018. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures, including the accumulation and communication of disclosures to the Company’s Chief Executive Officer and Chief Financial Officer as appropriate to allow timely decisions regarding required disclosure, are effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the rules and forms of the Securities and Exchange Commission (“SEC”).

There were no changes in our internal control over financial reporting that occurred during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

SEC guidance permits management to omit an assessment of an acquired business’ internal control over financial reporting from management’s assessment of internal control over financial reporting for a period not to exceed one year from the date of acquisition. Accordingly, we have not assessed ES&H Dallas’ internal control over financial reporting as of September 30, 2018.

Cautionary Statement for Purposes of “Safe Harbor Provisions” of the Private Securities Litigation Reform Act of 1995

This quarterly report on Form 10-Q contains forward-looking statements within the meaning of the federal securities laws. Statements that are not historical facts, including statements about the Company’s beliefs and expectations, are forward-looking statements. Forward-looking statements include statements preceded by, followed by or that include the words “may,” “could,” “would,” “should,” “believe,” “expect,” “anticipate,” “plan,” “estimate,” “target,” “project,” “intend” and similar expressions.

Forward-looking statements are only predictions and are not guarantees of performance. These statements are based on management’s beliefs and assumptions, which in turn are based on currently available information. Important assumptions include, among others, those regarding demand for Company services, expansion of service offerings geographically or through new or expanded service lines, the timing and cost of planned capital expenditures, competitive conditions and general economic conditions. These assumptions could prove inaccurate. Forward-looking statements also involve known and unknown risks and uncertainties, which could cause actual results to differ materially from those contained in any forward-looking statement. Many of these factors are beyond our ability to control or predict. Such factors include the replacement of non-recurring event cleanup projects, a loss of a major customer, our ability to permit and contract for timely construction of new or expanded disposal cells, our ability to renew our operating permits or lease agreements with regulatory bodies, loss of key personnel, compliance with and changes to applicable laws, rules, or regulations, access to insurance, surety bonds and other financial assurances, a deterioration in our labor relations or labor disputes, our ability to perform under required contracts, failure to realize anticipated benefits and operational performance from acquired operations, adverse economic or market conditions, government funding or competitive pressures, incidents or adverse weather conditions that could limit or suspend specific operations, access to cost effective transportation services, fluctuations in foreign currency markets, lawsuits, our willingness or ability to repurchase stock or pay dividends, implementation of new technologies, limitations on our available cash flow as a result of our indebtedness and our ability to effectively execute our acquisition strategy and integrate future acquisitions.

Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we are under no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. You should not place undue reliance on our forward-looking statements. Although we believe that the expectations reflected in forward-looking statements are reasonable, we cannot guarantee future results or performance. Before you invest in our common stock, you should be aware that the occurrence of the events described in the “Risk Factors” section in our Form 10-K for the fiscal year ended December 31, 2017 and in other reports we file with the SEC could harm our business, prospects, operating results, and financial condition.

Investors should also be aware that while we do, from time to time, communicate with securities analysts, it is against our policy to disclose to them any material non-public information or other confidential commercial information. Accordingly, stockholders should not assume that we agree with any statement or report issued by any analyst irrespective of the content of the statement or report. Furthermore, we have a policy against issuing or confirming financial forecasts or projections issued by others. Thus, to the extent that reports issued by securities analysts contain any projections, forecasts or opinions, such reports are not the responsibility of US Ecology, Inc.
