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, 2016. The results of operations for the three and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the entire year ending December 31, 2017.

The Company’s consolidated balance sheet as of December 31, 2016 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 January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350) . This ASU removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, under the ASU, “an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.” The guidance is effective prospectively for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. The Company early adopted ASU 2017-04 on January 1, 2017 and the standard is not expected to have a material impact 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 Accounting Standards Codification (“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 EITF’s consensuses reached on Issue 16-A. The guidance is effective for annual and interim periods beginning after December 15, 2017. The guidance must be applied

Table of Contents

retrospectively to all periods presented. Early adoption is permitted. We are currently assessing the impact the adoption of ASU 2016-18 may have on our consolidated 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 guidance must be applied retrospectively to all periods presented. Early adoption is permitted. We are currently assessing the impact the adoption of ASU 2016-15 may have on our consolidated cash flows.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) . This ASU requires excess tax benefits and tax deficiencies, which arise due to differences between the measure of compensation expense and the amount deductible for tax purposes, to be recorded directly through earnings as a component of income tax expense. Previously, these differences were generally recorded in additional paid-in capital and thus had no impact on net income. The change in treatment of excess tax benefits and tax deficiencies also impacts the computation of diluted earnings per share, and the cash flows associated with those items are classified as operating activities on the consolidated statements of cash flows. Additionally, ASU 2016-09 permits entities to make an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards. Forfeitures can be estimated, as allowed under previous standards, or recognized when they occur. The amendments in this ASU became effective in the first quarter of 2017. The Company adopted this ASU on January 1, 2017 and the standard did not have a material impact on its consolidated financial statements. Adoption of the ASU did not result in any cumulative effect adjustments to retained earnings or other components of stockholders’ equity as of the date of adoption, as well as there were no retrospective adjustments to our consolidated cash flows.

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. The guidance must be applied using the modified retrospective approach. Early adoption is permitted. We are currently assessing the impact the adoption of ASU 2016-02 may have on our consolidated financial position, results of operations and cash flows.

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 guidance permits the use of either the retrospective or cumulative effect transition method. The ASU also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. In August 2015, the FASB issued ASU 2015-14: Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date established in ASU 2014-09. The amendments in ASU 2014-09 are now effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted but not before annual periods beginning after December 15, 2016. The Company currently anticipates adopting this ASU using the modified retrospective method.

To assess the impact of ASU 2014-09, we have read the amended guidance, attended trainings and have consulted with external accounting professionals on a regular basis to assist with the understanding and interpretation of the ASU to our revenue recognition. The Company has completed our preliminary review of customer contracts in each of its operating segments for all significant service lines. Based upon the preliminary review of customer contracts, the Company believes that the majority of our standard contracts are not impacted by ASU 2014-09 revenue recognition criteria. We are in the process of performing additional analysis over non-standard contracts that may be impacted by the adoption of ASU 2014-09, to understand whether our revenue recognition is impacted. We are also performing additional analysis on revenue recognized from our managed services line of business, as the contractual provisions within this revenue stream can vary in comparison to our more standard contracts. Under ASU 2014-09, the principal vs. agent considerations differ from the current guidance and are more focused on the control aspect of the relationship. We are currently assessing the level of

Table of Contents

impact this guidance may have on our various revenue streams, to determine the appropriate classification under ASU 2014-09. Further, we are in the process of identifying and implementing appropriate changes to our business processes, systems and controls to support recognition and disclosure under the new standard.

While the Company continues to assess all potential impacts of adopting ASU 2014-09, based upon information available to date, the Company does not expect the adoption of ASU 2014-09 to have a significant impact on either the timing or recognition of revenues, however, the full extent of the impact is subject to the completion of our assessment.

NOTE 2. ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

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


	Foreign		Unrealized Loss
	Currency		on Interest Rate
	Translation		Hedge		Total
Balance at December 31, 2016	$	(12,649)	$	(2,076)	$	(14,725)

Balance at June 30, 2017	$	(10,658)	$	(1,737)	$	(12,395)

(1)

Before-tax reclassifications of $603,000 ($392,000 after-tax) and $1.3 million ( $873,000 after-tax) for the three and six months ended June 30, 2017, respectively, and before-tax reclassifications of $808,000 ($525,000 after-tax) and $1.6 million ($1.1 million after-tax) for the three and six months ended June 30, 2016, 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 $2.4 million ($1.6 million after-tax).

NOTE 3. CONCENTRATIONS AND CREDIT RISK

Major Customers

No customer accounted for more than 10% of total revenue for the three or six months ended June 30, 2017 or the three or six months ended June 30, 2016. No customer accounted for more than 10% of total trade receivables as of June 30, 2017 or December 31, 2016.

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 4. RECEIVABLES

Receivables consisted of the following:


	June 30,		December 31,

NOTE 5. 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 June 30, 2017, the fair value of the Company’s variable-rate debt was estimated to be $277.0 million.

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

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 interest rate swap continued to be effective following the termination of the Company’s senior secured credit agreement, dated June 17, 2014. 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 long-term liabilities in the Company’s consolidated balance sheet as of June 30, 2017 and December 31, 2016.

New Credit Agreement

On April 18, 2017, the Company entered into a new senior secured credit agreement (the “New Credit Agreement”) with Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent for the lenders, swingline lender and

Table of Contents

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 New 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. In connection with the Company’s entry into the New Credit Agreement, the Company terminated its existing credit agreement with Wells Fargo, dated June 17, 2014 (the “Former Credit Agreement”). Immediately prior to the termination of the Former Credit Agreement, there were $278.3 million of term loans and no revolving loans outstanding under the Former Credit Agreement. No early termination penalties were incurred as a result of the termination of the Former Credit Agreement. The Company wrote off certain unamortized deferred financing costs and original issue discount associated with the Former Credit Agreement that were to be amortized to interest expense in future periods through a one-time non-cash charge of $5.5 million to interest expense in the second quarter of 2017.

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 New 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 New 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 June 30, 2017, the effective interest rate on the Revolving Credit Facility, after giving effect to the impact of our interest rate swap, was 3.37%. 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 $200.0 million, or 72%, of the Revolving Credit Facility borrowings as of June 30, 2017. The interest rate swap agreement continued in place following the termination of the Company’s Former Credit Agreement. The critical terms of the interest rate swap and the forecasted transaction (periodic interest payments on the Company’s variable-rate debt) did not change as a result of the refinancing therefore the interest rate swap continues to qualify as a highly-effective 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 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 New Credit Agreement). The maximum letter of credit capacity under the Revolving Credit Facility is $75.0 million and the New Credit Agreement provides for a letter of credit fee equal to the applicable margin for LIBOR loans under the Revolving Credit Facility. At June 30, 2017, 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 New 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.

Table of Contents

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 June 30, 2017, there were no amounts outstanding subject to the Sweep Arrangement.

As of June 30, 2017, the availability under the Revolving Credit Facility was $216.7 million with $6.3 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 New 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 New Credit Agreement provides for mandatory prepayment at any time if the revolving credit outstandings exceed the revolving credit commitment (as such terms are defined in the New Credit Agreement), in an amount equal to such excess. Subject to certain exceptions, the New Credit 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 New 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 New 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 New Credit Agreement), among other things, amounts outstanding under the New Credit Agreement may be accelerated and the commitments may be terminated.

The New 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 New 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 June 30, 2017, we were in compliance with all of the financial covenants in the New Credit Agreement.

Former Credit Agreement

On June 17, 2014, the Company entered into a $540.0 million senior secured credit agreement (the “Former Credit Agreement”) with a syndicate of banks comprised of a $415.0 million term loan (the “Former Term Loan”) with a maturity date of June 17, 2021 and a $125.0 million revolving line of credit (the “Former Revolving Credit Facility”) with a maturity date of June 17, 2019.

The Former Term Loan provided an initial commitment amount of $415.0 million and bore interest at a base rate (as defined in the Former Credit Agreement) plus 2.00% or LIBOR plus 3.00%, at the Company’s option.

The Former Revolving Credit Facility provided up to $125.0 million of revolving credit loans or letters of credit with the use of proceeds restricted solely for working capital and other general corporate purposes. Under the Former Revolving Credit Facility, revolving loans were available based on a base rate (as defined in the Former Credit Agreement) or LIBOR, at the Company’s option, plus an applicable margin which was determined according to a pricing grid under which the

Table of Contents

interest rate decreased or increased based on our ratio of funded debt to consolidated earnings before interest, taxes, depreciation and amortization (as defined in the Former Credit Agreement). The maximum letter of credit capacity under the Former Revolving Credit Facility was $50.0 million and the Former Credit Agreement provided for a letter of credit fee equal to the applicable margin for LIBOR loans under the Former Revolving Credit Facility. At December 31, 2016, there were $2.2 million of working capital borrowings outstanding on the Former Revolving Credit Facility. These borrowings were due “on demand” and presented as short-term borrowings in the consolidated balance sheets.

NOTE 9. 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.

Changes to closure and post-closure obligations consisted of the following:

NOTE 10. INCOME TAXES

Our effective tax rate for the three months ended June 30, 2017 was 35.0%, down from 39.6% for the three months ended June 30, 2016. Our effective tax rate for the six months ended June 30, 2017 was 36.2%, down from 39.1% for the six months ended June 30, 2016. The decrease for the three and six months ended June 30, 2017 compared with the three and six months ended June 30, 2016 primarily reflects a higher proportion of earnings from our Canadian operations, which are taxed at a lower corporate tax rate. The effective tax rate for the three and six months ended June 30, 2017 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.

We file a consolidated U.S. federal income tax return with the Internal Revenue Service (“IRS”) as well as income tax returns in various states and Canada. US Ecology, Inc. is subject to examination by the IRS for tax years 2013 through 2016. EQ is also subject to examination by the IRS for tax years 2013 and 2014. We may be subject to examinations by the Canada Revenue Agency as well as various state and local taxing jurisdictions for tax years 2012 through 2016. We are currently not aware of any examinations by taxing authorities.

As discussed in Note 1 to the consolidated financial statements, the Company adopted ASU 2016-09 in the first quarter of 2017. The Company recorded all income tax effects of stock-based compensation awards in its provision for income taxes in the consolidated statement of operations on a prospective basis. Adoption of ASU 2016-09 resulted in net excess tax

Table of Contents

benefits in our provision for income taxes of $9,000 and $77,000 for the three and six months ended June 30, 2017. No other provisions of ASU 2016-09 had a material impact on the Company’s consolidated financial statements or disclosures.

NOTE 12. 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 six months ended June 30, 2017. The repurchase program will remain in effect until June 2, 2018, unless 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

Table of Contents

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 June 30, 2017, 1,149,001 shares of common stock remain available for grant under the Omnibus Plan.

PSUs, RSUs and Restricted Stock

On January 2, 2017, the Company granted 11,500 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, 2017, 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 $62.45 per unit. Compensation expense is recorded over the awards' vesting period.

Assumptions used in the Monte Carlo simulation to calculate the fair value of the PSUs granted in 2017 are as follows:


	2017
Stock price on grant date	$	49.15
Expected term (years)		3.0
Expected volatility		31	%
Risk-free interest rate		1.5	%

NOTE 13. 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 14. 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.

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

The primary financial measure used by management to assess segment performance is Adjusted EBITDA. 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 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 Board of Directors and Stockholders of

US Ecology, Inc.

Boise, Idaho

We have reviewed the accompanying consolidated balance sheet of US Ecology, Inc. and subsidiaries (the "Company") as of June 30, 2017, and the related consolidated statements of operations and comprehensive income for the three-month and six month periods ended June 30, 2017 and 2016, and cash flows for the six-month periods ended June 30, 2017 and 2016. This interim financial information is the responsibility of the Company's management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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 Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial information taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to such consolidated 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), the consolidated balance sheet of US Ecology, Inc. and subsidiaries as of December 31, 2016, 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 27, 2017, 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, 2016 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

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. The

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. 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.

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 June 30, 2017, approximately 23% of our T&D revenue was derived from Event Business projects, up from 20% for the three months ended June 30, 2016. For the three months ended June 30, 2017, Event Business revenue increased 24% compared to the three months ended June 30, 2016. For the six months ended June 30, 2017, approximately 19% of our T&D revenue was derived from Event Business projects, consistent with 19% for the six months ended June 30, 2016. For the six months ended June 30, 2017, Event Business revenue increased 7% compared to the six months ended June 30, 2016. 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 cause significant

Table of Contents

quarter-to-quarter and year-to-year differences in revenue, gross profit, gross margin, operating income and net income. Also, while we pursue many large projects months or years in advance of work performance, both large and small 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.

For the three months ended June 30, 2017, Base Business revenue increased 3% compared to the three months ended June 30, 2016. Base Business revenue was approximately 77% of total T&D revenue for the three months ended June 30, 2017, down from 80% for the three months ended June 30, 2016. For the six months ended June 30, 2017, Base Business revenue increased 3% compared to the six months ended June 30, 2016. Base Business revenue was approximately 81% of total T&D revenue for the six months ended June 30, 2017, consistent with 81% for the six months ended June 30, 2016. Our business is highly competitive and no assurance can be given that we will maintain these revenue levels or increase our market share.

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 bundling service strategy further drive the 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 also 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.

Revenue

Total revenue increased 3% to $126.1 million for the second quarter of 2017 compared with $122.4 million for the second quarter of 2016.

Environmental Services

Environmental Services segment revenue increased 8% to $89.6 million for the second quarter of 2017 compared to $82.8 million for the second quarter of 2016. T&D revenue increased 6% compared to the second quarter of 2016, primarily as a result of a 24% increase in project-based Event Business revenue and a 3% increase in Base Business revenue. Transportation service revenue increased 15% compared to the second quarter of 2016, reflecting more Event Business projects utilizing the Company’s transportation and logistics services. Total tons of waste disposed of or processed across all of our facilities increased 5% for the second quarter of 2017 compared to the second quarter of 2016. Tons of waste disposed of or processed at our landfills increased 19% for the second quarter of 2017 compared to the second quarter of 2016.

T&D revenue from recurring Base Business waste generators increased 3% for the second quarter of 2017 compared to the second quarter of 2016 and comprised 77% of total T&D revenue for the second quarter of 2017. During the second quarter of 2017, increases in Base Business T&D revenue from the refining, metal manufacturing, and “Other” industry groups were partially offset by a decrease in Base Business T&D revenue from the broker/TSDF industry group.

T&D revenue from Event Business waste generators increased 24% for the second quarter of 2017 compared to the second quarter of 2016 and comprised 23% of total T&D revenue for the second quarter of 2017. During the second quarter of 2017, increases in Event Business T&D revenue from the “Other”, chemical manufacturing and government industry groups were partially offset by decreases in Event Business T&D revenue from the refining and general manufacturing industry groups.

Field & Industrial Services

Field & Industrial Services segment revenue decreased 8% to $36.5 million for the second quarter of 2017 compared with $39.6 million for the second quarter of 2016. The decrease in Field & Industrial Services segment revenue is primarily attributable to the expiration of a contract that was not renewed or replaced and softer overall market conditions for industrial and remediation services.

Gross Profit

Total gross profit decreased 3% to $35.9 million for the second quarter of 2017, down from $36.9 million for the second quarter of 2016. Total gross margin was 28% for the second quarter of 2017 compared with 30% for the second quarter of 2016.

Environmental Services

Environmental Services segment gross profit increased less than 1% to $30.7 million for the second quarter of 2017, up from $30.6 million for the second quarter of 2016. Total segment gross margin for the second quarter of 2017 was 34% compared with 37% for the second quarter of 2016. T&D gross margin was 38% for the second quarter of 2017 compared with 42% for the second quarter of 2016. The decrease in T&D gross margin primarily reflects the impact of the temporary closure of one of our treatment facilities during the second quarter of 2017 due to severe wind damage.

Field & Industrial Services

Field & Industrial Services segment gross profit decreased 17% to $5.2 million for the second quarter of 2017, down from $6.3 million for the second quarter of 2016. Total segment gross margin was 14% for the second quarter of 2017 compared with 16% for the second quarter of 2016. The decrease in segment gross margin is primarily attributable to lower revenue and a less favorable service mix in the second quarter of 2017 compared to the second quarter of 2016.

Selling, General and Administrative Expenses (“SG&A”)

Total SG&A was $20.0 million, or 16% of total revenue, for the second quarter of 2017 compared with $19.8 million, or 16% of total revenue, for the second quarter of 2016.

Table of Contents

Environmental Services

Environmental Services segment SG&A decreased 5% to $5.3 million, or 6% of segment revenue, for the second quarter of 2017 compared with $5.5 million, or 7% of segment revenue, for the second quarter of 2016, primarily reflecting the recognition of insurance proceeds related to the repair of one of our treatment facilities, which suffered severe wind damage, partially offset by higher employee labor costs, higher professional services expenses and higher rental expenses in the second quarter of 2017 compared to the second quarter of 2016. We expect to recognize additional insurance proceeds in the second half of 2017 upon settlement of our business interruption insurance claim for lost profits during the period our treatment facility was temporarily closed.

Field & Industrial Services segment SG&A remained consistent at $2.6 million, or 7% of segment revenue, for the second quarter of 2017 compared with $2.6 million, or 7% of segment revenue, for the second quarter of 2016.

Corporate

Corporate SG&A was $12.1 million, or 10% of total revenue, for the second quarter of 2017 compared with $11.7 million, or 10% of total revenue, for the second quarter of 2016, primarily reflecting higher employee labor costs, partially offset by lower business development costs in the second quarter of 2017 compared with the second quarter of 2016.

Components of Adjusted EBITDA

Income tax expense

Our effective income tax rate for the second quarter of 2017 was 35.0% compared with 39.6% for the second quarter of 2016. The decrease primarily reflects a higher proportion of earnings from our Canadian operations, which are taxed at a lower corporate tax rate, in the second quarter of 2017 compared with the second quarter of 2016. The effective tax rate for the three months ended June 30, 2017 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 Accounting Standards Update 2016-09.

Interest expense

Interest expense was $8.5 million for the second quarter of 2017 compared with $4.3 million for the second quarter of 2016. The Company wrote off certain unamortized deferred financing costs and original issue discount associated with the Former Credit Agreement that were to be amortized to interest expense in future periods through a one-time non-cash charge of $5.5 million to interest expense in the second quarter of 2017. This increase is partially offset by lower debt levels in the second quarter of 2017 compared to the second quarter of 2016, and a lower effective interest rate under the New Credit Agreement compared to the Former Credit Agreement.

Foreign currency gain (loss)

We recognized a $158,000 non-cash foreign currency gain for the second quarter of 2017 compared with a $343,000 non-cash foreign currency loss for the second quarter of 2016. 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 June 30, 2017, we had $18.8 million of intercompany loans subject to currency revaluation.

Table of Contents

Other income

Other income for the second quarter of 2016 includes approximately $2.2 million related to the gain on sale of the Augusta, Georgia facility in April 2016 and final closing adjustments on the divestiture of our Allstate Power Vac, Inc. (“Allstate”) subsidiary to a private investor group recorded in the second quarter of 2016.

Depreciation and amortization of plant and equipment

Depreciation and amortization expense was $7.0 million for the second quarter of 2017 compared with $6.2 million for the second quarter of 2016.

Amortization of intangibles

Intangible assets amortization expense was $2.6 million for the second quarter of 2017 compared with $2.6 million for the second quarter of 2016.

Stock-based compensation

Stock-based compensation expense increased 33% to $1.0 million for the second quarter of 2017 compared with $783,000 for the second quarter of 2016 as a result of an increase in equity-based awards granted to employees.

Accretion and non-cash adjustment of closure and post-closure liabilities

Accretion and non-cash adjustment of closure and post-closure liabilities was $1.1 million for the second quarter of 2017 compared with $1.0 million for the second quarter of 2016.

Revenue

Total revenue increased less than 1% to $236.3 million for the first six months of 2017 compared with $235.7 million for the first six months of 2016.

Environmental Services

Environmental Services segment revenue increased 4% to $170.9 million for the first six months of 2017 compared to $164.3 million for the first six months of 2016. T&D revenue increased 5% compared to the first six months of 2016,

Table of Contents

primarily as a result of a 7% increase in project-based Event Business revenue and a 3% increase in Base Business revenue. Transportation service revenue for the first six months of 2017 was consistent with the first six months of 2016. Total tons of waste disposed of, or processed, across all of our facilities increased 4% for the first six months of 2017 compared to the first six months of 2016. Tons of waste disposed of or processed at our landfills increased 9% for the first six months of 2017 compared to the first six months of 2016.

T&D revenue from recurring Base Business waste generators increased 3% for the first six months of 2017 compared to the first six months of 2016 and comprised 81% of total T&D revenue for the first six months of 2017. During the first six months of 2017, increases in Base Business T&D revenue from the refining, “Other” and metal manufacturing industry groups were partially offset by decreases in Base Business T&D revenue from the broker/TSDF and transportation industry groups.

T&D revenue from Event Business waste generators increased 7% for the first six months of 2017 compared to the first six months of 2016 and comprised 19% of total T&D revenue for the first six months of 2017. During the first six months of 2017, increases in Event Business T&D revenue from the “Other” and chemical manufacturing industry groups were partially offset by decreases in Event Business T&D revenue from the utilities and mining, exploration & production industry groups.

The following table summarizes combined Base Business and Event Business T&D revenue growth, within the Environmental Services segment, by generator industry for the first six months of 2017 as compared to the first six months of 2016:

Field & Industrial Services

Field & Industrial Services segment revenue decreased 8% to $65.4 million for the first six months of 2017 compared with $71.4 million for the first six months of 2016. The decrease in Field & Industrial Services segment revenue is primarily attributable to the expiration of a contract that was not renewed or replaced and softer overall market conditions for industrial and remediation services.

Gross Profit

Total gross profit decreased 6% to $67.8 million for the first six months of 2017, down from $72.1 million for the first six months of 2016. Total gross margin was 29% for the first six months of 2017 compared with 31% for the first six months of 2016.

Environmental Services

Environmental Services segment gross profit decreased 3% to $59.4 million for the first six months of 2017, down from $61.1 million for the first six months of 2016. Total segment gross margin for the first six months of 2017 was 35% compared with 37% for the first six months of 2016. T&D gross margin was 38% for the first six months of 2017 compared

Table of Contents

with 41% for the first six months of 2016. The decrease in T&D gross margin primarily reflects the impact of the temporarily closure of one of our treatment facilities due to severe wind damage as well as a less favorable service mix in the first six months of 2017 compared to the first six months of 2016.

Field & Industrial Services

Field & Industrial Services segment gross profit decreased 24% to $8.4 million for the first six months of 2017, down from $11.1 million for the first six months of 2016. Total segment gross margin was 13% for the first six months of 2017 compared with 16% for the first six months of 2016. The decrease in segment gross margin is primarily attributable to lower revenue and a less favorable service mix in the first six months of 2017 compared to the first six months of 2016.

Selling, General and Administrative Expenses (“SG&A”)

Total SG&A was $39.7 million, or 17% of total revenue, for the first six months of 2017 compared with $39.2 million, or 17% of total revenue, for the first six months of 2016.

Environmental Services

Environmental Services segment SG&A decreased 1% to $11.0 million, or 6% of segment revenue, for the first six months of 2017 compared with $11.1 million, or 7% of segment revenue, for the first six months of 2016, primarily reflecting the recognition of insurance proceeds related to the repair of one of our large treatment facilities, which suffered severe wind damage, partially offset by higher employee labor costs, higher professional services expenses, higher rental expenses and higher insurance costs in the first six months of 2017 compared to the first six months of 2016.

Field & Industrial Services

Field & Industrial Services segment SG&A increased 4% to $5.3 million, or 8% of segment revenue, for the first six months of 2017 compared with $5.1 million, or 7% of segment revenue, for the first six months of 2016. The increase in segment SG&A primarily reflects higher worker’s compensation costs and higher equipment and supplies expenses in the first six months of 2017 compared with the first six months of 2016.

Corporate

Corporate SG&A was $23.5 million, or 10% of total revenue, for the first six months of 2017 compared with $23.1 million, or 10% of total revenue, for the first six months of 2016, primarily reflecting higher employee labor costs, partially offset by lower business development costs in the first six months of 2017 compared with the first six months of 2016.

Components of Adjusted EBITDA

Income tax expense

Our effective income tax rate for the first six months of 2017 was 36.2% compared with 39.1% for the first six months of 2016. The decrease primarily reflects a higher proportion of earnings from our Canadian operations, which are taxed at a lower corporate tax rate, in the first six months of 2017 compared with the first six months of 2016. The effective tax rate for the six months ended June 30, 2017 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 Accounting Standards Update 2016-09.

Interest expense

Interest expense was $12.6 million for the first six months of 2017 compared with $8.9 million for the first six months of 2016. The Company wrote off certain unamortized deferred financing costs and original issue discount associated with the Former Credit Agreement that were to be amortized to interest expense in future periods through a one-time non-cash charge of $5.5 million to interest expense in the second quarter of 2017. This increase is partially offset by lower debt

Table of Contents

levels in the first six months of 2017 compared to the first six months of 2016, and a lower effective interest rate under the New Credit Agreement compared to the Former Credit Agreement.

Foreign currency gain (loss)

We recognized a $246,000 non-cash foreign currency gain for the first six months of 2017 compared with a $416,000 non-cash foreign currency gain for the first six months of 2016. Foreign currency gains and losses reflect changes in business activity conducted in a currency other than the USD, our functional currency. Additionally, we established intercompany loans between our Canadian subsidiaries, whose functional currency is the 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 June 30, 2017, we had $18.8 million of intercompany loans subject to currency revaluation.

Other income

Other income for the first six months of 2016 includes approximately $2.2 million related to the gain on sale of the Augusta, Georgia facility in April 2016 and final closing adjustments on the Allstate divestiture recorded in the second quarter of 2016.

Depreciation and amortization of plant and equipment

Depreciation and amortization expense was $13.6 million for the first six months of 2017 compared with $12.1 million for the first six months of 2016.

Amortization of intangibles

Intangible assets amortization expense was $5.3 million for the first six months of 2017 compared with $5.3 million for the first six months of 2016.

Stock-based compensation

Stock-based compensation expense increased 24% to $2.0 million for the first six months of 2017 compared with $1.6 million for the first six months of 2016 as a result of an increase in equity-based awards granted to employees.

Accretion and non-cash adjustment of closure and post-closure liabilities

Accretion and non-cash adjustment of closure and post-closure liabilities was $2.2 million for the first six months of 2017 compared with $2.0 million for the first six months of 2016.

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, 2016.

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” of this Form 10-Q.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity are cash and cash equivalents, cash generated from operations and borrowings under the new senior secured credit agreement (the “New Credit Agreement”). At June 30, 2017, we had $4.9 million in cash and cash equivalents immediately available and $216.7 million of borrowing capacity available under our New 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 and required principal payments 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 New Credit Agreement provide additional sources of liquidity should they be required.

Operating Activities

For the six months ended June 30, 2017, net cash provided by operating activities was $30.8 million. This primarily reflects net income of $10.2 million, non-cash depreciation, amortization and accretion of $21.1 million, an increase in accounts payable and accrued liabilities of $5.8 million, amortization and write-off of debt issuance costs of $5.6 million, an increase in deferred revenue of $4.8 million and a decrease in income taxes receivable of $2.0 million, partially offset by an increase in accounts receivable of $14.5 million and an increase in other assets of $4.0 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 accounts receivable 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.

Days sales outstanding were 77 days as of June 30, 2017, compared to 73 days as of December 31, 2016 and 74 days as of June 30, 2016.

For the six months ended June 30, 2016, net cash provided by operating activities was $38.7 million. This primarily reflects net income of $16.5 million, non-cash depreciation, amortization and accretion of $19.4 million, a decrease in accounts receivable of $6.6 million, share-based compensation expense of $1.6 million, a decrease in other assets of $1.3 million, and non-cash amortization of debt issuance costs of $1.1 million, partially offset by the gain recognized on the divestiture of the Augusta, Georgia facility in April 2016 and final closing adjustments on the Allstate divestiture of $2.2 million, an increase in income taxes receivable of $1.4 million, a decrease in deferred income taxes of $1.3 million, a decrease in deferred revenue of $1.2 million, a decrease in accounts payable and accrued liabilities of $872,000 and a decrease in closure and post-closure obligations of $848,000. Impacts on net income are due to the factors discussed above under “Results of Operations.” The decrease in receivables is primarily attributable to the timing customer payments. The increase in income taxes receivable is primarily attributable to the timing of estimated income tax payments. The decrease in deferred revenue is primarily attributable to the timing of the treatment and disposal of waste received but not yet processed. The decrease in closure and post-closure obligations is primarily attributable to payments made for closure and post-closure activities primarily at our closed landfills.

Investing Activities

For the six months ended June 30, 2017, net cash used in investing activities was $17.5 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.

For the six months ended June 30, 2016, net cash used in investing activities was $16.7 million, primarily related to capital expenditures of $14.5 million and the purchase of Environmental Services Inc., (“ESI”), for $4.9 million, net of cash acquired, partially offset by proceeds from the divestiture of our Augusta, Georgia facility for $2.7 million, net of cash divested. Significant capital projects included construction of additional disposal capacity at our Blainville, Quebec,

Table of Contents

Canada and Robstown, Texas facilities and equipment purchases and infrastructure upgrades at our corporate and operating facilities.

Financing Activities

For the six months ended June 30, 2017, net cash used in financing activities was $15.7 million, consisting primarily of $283.0 million of repayment of the Company’s long-term debt under the Former Credit Agreement, $281.0 million of initial proceeds from the issuance of long-term debt under the New Credit Agreement, $4.0 million of subsequent payments of long-term debt under the New Credit Agreement, $7.8 million of dividend payments to our stockholders and net payment activity on the Company’s short-term borrowings of $2.2 million.

For the six months ended June 30, 2016, net cash used in financing activities was $15.4 million, consisting primarily of $11.5 million of payments on the Company’s long-term debt under the Former Credit Agreement and $7.8 million of dividend payments to our stockholders, partially offset by $4.0 million of net short-term borrowings under the Former Credit Agreement to fund working capital requirements.

New Credit Agreement

The New 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 New 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 New 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 New Credit Agreement).

At June 30, 2017, the effective interest rate on the Revolving Credit Facility, including the impact of our interest rate swap, was 3.37%. 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 $200.0 million, or 72%, of the Revolving Credit Facility borrowings as of June 30, 2017. The interest rate swap agreement continued to be effective following the termination of the Company’s Former Credit Agreement.

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 New Credit Agreement). The maximum letter of credit capacity under the Revolving Credit Facility is $75.0 million and the New Credit Agreement provides for a letter of credit fee equal to the applicable margin for LIBOR loans under the Revolving Credit Facility. At June 30, 2017, 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 New Credit Agreement) and 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 June 30, 2017, there were no amounts outstanding subject to the Sweep Arrangement.

As of June 30, 2017, the availability under the Revolving Credit Facility was $216.7 million with $6.3 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.

CONTRACTUAL OBLIGATIONS AND GUARANTEES

Except as set forth in the paragraph below, there were no material changes in the amounts of our contractual obligations and guarantees during the six months ended June 30, 2017. 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, 2016.

On April 18, 2017, the Company entered into the New Credit Agreement. In connection with the Company’s entry into the New Credit Agreement, the Company terminated the Former Credit Agreement. For more information about our refinancing, see Note 8 of the Notes to Consolidated Financial Statements in “Part I, Item 1. Financial Statements (Unaudited)” of this Quarterly Report on Form 10-Q.

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 June 30, 2017, $5.8 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 New Credit Agreement. Under the New Credit Agreement, Revolving Credit Facility borrowings incur interest at a base rate (as defined in the New 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 New 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. The interest rate swap agreement continued to be effective following the termination of the Company’s Former Credit Agreement. Under the terms of the swap, the Company pays interest at the fixed effective rate of 5.17% and receives interest at the variable one-month LIBOR rate on an initial notional amount of $250.0 million.

As of June 30, 2017, there were $277.0 million of revolving loans outstanding under the New 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 New Credit Agreement.

Based on the outstanding indebtedness of $277.0 million under the New Credit Agreement at June 30, 2017 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 $845,000 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 six months ended June 30, 2017, our Canadian subsidiaries transacted approximately 56% 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. 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.

Table of Contents

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 June 30, 2017, we had $18.8 million of intercompany loans outstanding between our Canadian subsidiaries and US Ecology. During the six months ended June 30, 2017, the CAD strengthened as compared to the USD resulting in a $536,000 non-cash foreign currency translation gain being recognized in the Company’s consolidated statements of operations related to the intercompany loans. Based on intercompany balances as of June 30, 2017, a $0.01 CAD increase or decrease in currency rate compared to the USD at June 30, 2017 would have generated a gain or loss of approximately $188,000 for the six months ended June 30, 2017.

We had a total pre-tax foreign currency gain of $246,000 for the six months ended June 30, 2017. 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 June 30, 2017. 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.

PART II - OTHER INFORMATION

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. These statements include, among others, statements regarding our financial and operating results, strategic objectives and means to achieve those objectives, the amount and timing of capital expenditures, repurchases of its stock under approved stock repurchase plans, the amount and timing of interest expense, the likelihood of our success in expanding our business, financing plans, budgets, working capital needs and sources of liquidity.

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, 2016 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.
