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, 2015. The results of operations for the three months ended March 31, 2016 are not necessarily indicative of the results to be expected for the entire year ending December 31, 2016. For comparative purposes, certain amounts in prior periods’ consolidated financial statements have been reclassified to conform to the current period presentation.

On November 1, 2015, we sold our Allstate Power Vac, Inc. (“Allstate”) subsidiary to a private investor group. See Note 2 for additional information.

The Company’s consolidated balance sheet as of December 31, 2015 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 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 March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718). This ASU was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. The update is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. We are assessing the impact the adoption of ASU 2016-09 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. We are currently assessing the impact the adoption of ASU 2014-09 may have on our consolidated financial position, results of operations and cash flows.

NOTE 2.DIVESTITURE

On November 1, 2015, we completed the divestiture of Allstate for cash proceeds at closing of $58.8 million. For the year ended December 31, 2015, we recognized a pre-tax loss on the divestiture of Allstate, including transaction-related costs, of $542,000, which was included in Other income (expense) in our consolidated statements of operations. Prior to the divesture, Allstate represented the majority of the industrial services business included in our Field & Industrial Services segment. The sale of Allstate did not meet the requirements to be reported as a discontinued operation as defined in ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. See Note 5 to the Consolidated Financial Statements in “Part II, Item 8. Financial Statements and Supplementary Data” of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 for additional information.

No post-closing adjustments were recorded during the three months ended March 31, 2016. On April 25, 2016, we received additional cash proceeds of $827,000 in settlement of final post-closing adjustments, resulting in a pre-tax gain to be recognized in the second quarter of 2016.

NOTE 3.ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

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

	Foreign Currency Translation			Unrealized Loss on Interest Rate Hedge			Total
Balance at December 31, 2015	$	(14,028	)	$	(3,038	)	$	(17,066	)
Other comprehensive income (loss) before reclassifications, net of tax	3,253			(2,430		)	823
Amounts reclassified out of AOCI, net of tax (1)	—			536			536
Other comprehensive income (loss)	3,253			(1,894		)	1,359
Balance at March 31, 2016	$	(10,775	)	$	(4,932	)	$	(15,707	)

(1)  Before-tax reclassifications of $826,000 ($536,000 after-tax) and $888,000 ($577,000 after-tax) for the three months ended March 31, 2016 and 2015, respectively, were included in Interest expense in the Company’s consolidated statements of operations. Amounts relate to our 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 debt are made. Amounts in AOCI expected to be recognized in interest expense over the next 12 months total approximately $3.3 million ($2.1 million after tax).

NOTE 4.CONCENTRATIONS AND CREDIT RISK

Major Customers

No customer accounted for more than 10% of total revenue for the three months ended March 31, 2016 or 2015. No customer accounted for more than 10% of total trade receivables as of March 31, 2016 or December 31, 2015.

Credit Risk Concentration

We maintain most of our cash and cash equivalents with nationally recognized financial institutions like Wells Fargo Bank, National Association (“Wells Fargo”) and Comerica, Inc. 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 5.RECEIVABLES

Receivables consisted of the following:

	March 31,			December 31,
$s in thousands	2016			2015
Trade	$	81,911		$	95,055
Unbilled revenue	14,407			11,983
Other	1,037			2,568
Total receivables	97,355			109,606
Allowance for doubtful accounts	(3,570		)	(3,226		)
Receivables, net	$	93,785		$	106,380

NOTE 6.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 March 31, 2016, the fair value of the Company’s variable-rate debt was estimated to be $289.0 million.

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.

(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 long-term liabilities in the Company’s consolidated balance sheet as of March 31, 2016 and December 31, 2015.

On June 17, 2014, in connection with the acquisition of EQ Holdings, Inc. and its wholly-owned subsidiaries (collectively “EQ”), the Company entered into a new $540.0 million senior secured credit agreement (the “Credit Agreement”) with a syndicate of banks comprised of a $415.0 million term loan (the “Term Loan”) with a maturity date of June 17, 2021 and a $125.0 million revolving line of credit (the “Revolving Credit Facility”) with a maturity date of June 17, 2019. Upon entering into the Credit Agreement, the Company terminated its existing credit agreement with Wells Fargo, dated October 29, 2010, as amended (the “Former Agreement”). Immediately prior to the termination of the Former Agreement, there were no outstanding borrowings under the Former Agreement. No early termination penalties were incurred as a result of the termination of the Former Agreement.

Term Loan

The Term Loan provided an initial commitment amount of $415.0 million, the proceeds of which were used to acquire 100% of the outstanding shares of EQ and pay related transaction fees and expenses. The Term Loan bears interest at a base rate (as defined in the Credit Agreement) plus 2.00% or LIBOR plus 3.00%, at the Company’s option. The Term Loan is subject to amortization in equal quarterly installments in an aggregate annual amount equal to 1.00% of the original principal amount of the Term Loan. At March 31, 2016, the effective interest rate on the Term Loan, including the impact of our interest rate swap, was 4.72%. Interest only payments are due either monthly or on the last day of any interest period, as applicable. As set forth in the Credit Agreement, the Company is required to enter into one or more interest rate hedge agreements in amounts sufficient to fix the interest rate on at least 50% of the principal amount of the $415.0 million Term Loan. In October 2014, the Company entered into an interest rate swap agreement with Wells Fargo, effectively fixing the interest rate on $225.0 million, or 78%, of the Term Loan principal outstanding as of March 31, 2016.

Revolving Credit Facility

The Revolving Credit Facility provides 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 Revolving Credit Facility, revolving 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 earnings before interest, taxes, depreciation and amortization (“EBITDA”). The Company is required to pay a commitment fee of 0.50% per annum on the unused portion of the Revolving Credit Facility, with such commitment fee to be reduced based upon the Company’s total leverage ratio as defined in the Credit Agreement. The maximum letter of credit capacity under the Revolving Credit Facility is $50.0 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. Interest only payments are due either monthly or on the last day of any interest period, as applicable. At March 31, 2016, there were no borrowings outstanding on the Revolving Credit Facility. As of March 31, 2016, the availability under the Revolving Credit Facility was $117.3 million with $7.7 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.

Except as set forth below, the Company may prepay the Term Loan or permanently reduce the Revolving Credit Facility commitment under the Credit Agreement at any time without premium or penalty (other than customary “breakage” costs with respect to the early termination of LIBOR loans). Subject to certain exceptions, the Credit Agreement provides for mandatory prepayment upon certain asset dispositions, casualty events and issuances of indebtedness. The Credit Agreement is also subject to mandatory annual prepayments commencing in December 2015 if our total leverage (defined as the ratio of our consolidated funded debt as of the last day of the applicable fiscal year to our adjusted EBITDA for such period) exceeds certain ratios as follows: 50% of our adjusted excess cash flow (as defined in the Credit Agreement and which takes into account certain adjustments) if our total leverage ratio is greater than 2.50 to 1.00, with step-downs to 0% if our total leverage ratio is equal to or less than 2.50 to 1.00.

12

Pursuant to (i) an unconditional guarantee agreement (the “Guarantee”) and (ii) a collateral agreement, each entered into by the Company and its domestic subsidiaries on June 17, 2014, the Company’s obligations under the Credit Agreement are 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 the Credit Agreement is secured by substantially all of the Company’s and its domestic subsidiaries’ assets except the Company’s and its domestic subsidiaries’ real property.

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. We may only declare quarterly or annual dividends if on the date of declaration, no event of default has occurred and no other event or condition has occurred that would constitute default due to the payment of the dividend.

The Credit Agreement also contains a financial maintenance covenant, which is a maximum Consolidated Senior Secured Leverage Ratio, as defined in the Credit Agreement, and is only applicable to the Revolving Credit Facility. Our Consolidated Senior Secured Leverage Ratio as of the last day of any fiscal quarter, commencing with June 30, 2014, may not exceed the ratios indicated below:

Fiscal Quarters Ending	Maximum Ratio
December 31, 2015 through September 30, 2016	3.75 to 1.00
December 31, 2016 through September 30, 2017	3.50 to 1.00
December 31, 2017 through September 30, 2018	3.25 to 1.00
December 31, 2018 and thereafter	3.00 to 1.00

At March 31, 2016, we were in compliance with all of the financial covenants in the Credit Agreement.

NOTE 10.             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 11.INCOME TAXES

Our effective tax rate for the three months ended March 31, 2016 was 38.4%, up from 33.1% for the three months ended March 31, 2015. The increase for the three months ended March 31, 2016 primarily reflects a lower proportion of earnings from our Canadian operations, which are taxed at a lower corporate tax rate, for the three months ended March 31, 2016 compared with the three months ended March 31, 2015. The increase is also partially attributable to a higher U.S. effective tax rate for the three months ended March 31, 2016 which is primarily driven by a higher overall effective state tax rate resulting from changes in our apportionment between the various states in which we operate.

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. During the three months ended March 31, 2016, the US Ecology, Inc. IRS examination for the 2012 tax year concluded with no material changes. US Ecology, Inc. is subject to examination by the IRS for tax years 2013 through 2015. EQ is currently under IRS examination for the 2012 tax year and also remains subject to examination by the IRS for tax years 2013 through 2015. The Company is indemnified by the previous owners of EQ for any pre-acquisition tax liabilities. We may be subject to examinations by the Canada Revenue Agency as well as various state and local taxing jurisdictions for tax years 2011 through 2015. We are currently not aware of any other examinations by taxing authorities.

NOTE 13.EQUITY

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”), and 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 March 31, 2016, 1,249,752 shares of common stock remain available for grant under the Omnibus Plan.

PSUs, RSUs and Restricted Stock

On January 4, 2016, the Company granted 16,000 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, 2016, 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 $41.22 per unit. Compensation expense is recorded over the awards’ vesting period.

14

Assumptions used in the Monte Carlo simulation to calculate the fair value of the PSUs granted in 2016 and 2015 are as follows:

	2016			2015
Stock price on grant date	$	35.05		$	46.89
Expected term (years)	3.0			2.6
Expected volatility	29		%	29		%
Risk-free interest rate	1.3		%	0.9		%

NOTE 14.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 our 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.

15

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 15.   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.

Effective January 1, 2016, we changed our internal reporting structure by moving the financial results of our Sulligent, Alabama and Tampa, Florida locations from our Environmental Services segment to our Field & Industrial Services segment. The purpose of this change is to align our internal reporting structure with how we manage our business based on the primary service offering of each location. Throughout this Quarterly Report on Form 10-Q, our segment results for all periods presented have been recast to reflect this change.

Summarized financial information of our reportable segments is as follows:

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, which are not considered part of usual business operations. 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 March 31, 2016, and the related consolidated statements of operations, comprehensive income, and cash flows for the three-month periods ended March 31, 2016 and 2015. 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, 2015, 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 29, 2016, 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, 2015 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.

On November 1, 2015, we sold our Allstate Power Vac, Inc. (“Allstate”) subsidiary to a private investor group. See Note 2 to the Consolidated Financial Statements in “Part I, Item 1. Financial Statements (Unaudited)” in this Quarterly Report on Form 10-Q for additional information.

Our operations are managed in two reportable segments reflecting our internal management 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.

Effective January 1, 2016, we changed our internal reporting structure by moving the financial results of our Sulligent, Alabama and Tampa, Florida locations from our Environmental Services segment to our Field & Industrial Services segment. The purpose of this change is to align our internal reporting structure with how we manage our business based on the primary service offering of each location. Throughout this Quarterly Report on Form 10-Q, our segment results for all periods presented have been recast to reflect this change.

21

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 composition of Environmental Services segment T&D revenues by waste generator industry for the three months ended March 31, 2016 and 2015 were as follows:

	% of Treatment and Disposal Revenue (1) for the Three Months Ended March 31,
Generator Industry	2016	2015
Metal Manufacturing	16%	16%
Broker / Treatment, Storage & Disposal Facilities (“TSDF”)	15%	15%
Chemical Manufacturing	14%	25%
Refining	12%	10%
General Manufacturing	11%	9%

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 March 31, 2016, approximately 17% of our T&D revenue was derived from Event Business projects, down from 28% for the three months ended March 31, 2015. For the three months ended March 31, 2016, Event Business revenue decreased 44% compared to the three months ended March 31, 2015. 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 redevelopment 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 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 clean-up 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 March 31, 2016, Base Business revenue increased 7% compared to the three months ended March 31, 2015. Base Business revenue was approximately 83% of total T&D revenue for the three months ended March 31, 2016, up from 72% for the three months ended March 31, 2015. 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.

22

To maximize utilization of our railcar fleet, we periodically deploy available railcars to transport waste from clean-up sites to disposal facilities operated by other companies. Such transportation services may also be bundled with for-profit logistics and field services support work.

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 clean-up 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.

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, which are not considered part of usual business operations. The reconciliation of Adjusted EBITDA to Net Income is as follows:

	Three Months Ended March 31,						2016 vs. 2015
$s in thousands	2016			2015			$ Change			% Change
Adjusted EBITDA	$	26,116		$	27,230		$	(1,114	)	-4%

Net Income	$	7,517		$	5,865		$	1,652		28%

Adjusted EBITDA is a complement to results provided in accordance with accounting principles generally accepted in the United States (“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.

Revenue

Total revenue decreased 17% to $113.3 million for the first quarter of 2016 compared with $136.7 million for the first quarter of 2015.

Environmental Services

Environmental Services segment revenue decreased 7% to $81.5 million for the first quarter of 2016 compared to $87.4 million for the first quarter of 2015. T&D revenue decreased 7% in the first quarter of 2016, primarily as a result of a 44% decrease in project-based Event Business. Transportation service revenue decreased 5% compared to the first quarter of 2015, reflecting fewer Event Business projects utilizing the Company’s transportation and logistics services. Tons of waste disposed of or processed decreased 15% for the first quarter of 2016 compared to the first quarter of 2015.

24

T&D revenue from recurring Base Business waste generators increased 7% for the first quarter of 2016 compared to the first quarter of 2015 and comprised 83% of total T&D revenue. During the first quarter of 2016, increases in Base Business T&D revenue from the refining, “Other” and general manufacturing industry groups were partially offset by decreases in T&D revenue from Base Business in the chemical manufacturing and government industry groups.

T&D revenue from Event Business waste generators decreased 44% for the first quarter of 2016 compared to the first quarter of 2015 and was 17% of T&D revenue for the first quarter of 2016. The decrease in Event Business T&D revenue compared to the prior year primarily reflects lower T&D revenue from the chemical manufacturing, refining and metal manufacturing industry groups, partially offset by higher T&D revenue from the “Other” and utilities industry groups. The decrease in revenue from the chemical manufacturing industry group is primarily attributable to the completion of a large East Coast remedial cleanup project in the third quarter of 2015. The decrease in revenue from the refining industry group is primarily attributable to lower volumes of refinery Event Business. The decrease in revenue from the metals manufacturing industry group primarily reflects lower industry activity due to lower commodity prices.

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 quarter of 2016 as compared to the first quarter of 2015:

	Treatment and Disposal Revenue Growth Three Months Ended March 31, 2016 vs. Three Months Ended March 31, 2015
Other	51%
Utilities	36%
Transportation	14%
Mining, Exploration & Production	13%
General Manufacturing	11%
Refining	5%
Broker / TSDF	-3%
Metal Manufacturing	-6%
Waste Management & Remediation	-6%
Government	-15%
Chemical Manufacturing	-50%

Field & Industrial Services

Field & Industrial Services segment revenue decreased 35% to $31.8 million for the first quarter of 2016 compared with $49.3 million for the first quarter of 2015. The Allstate business, divested on November 1, 2015, contributed segment revenue of $13.9 million in the first quarter of 2015. The remaining decrease in segment revenue is primarily attributable to a decrease in transportation-related revenues as a result of the completion of a large East Coast remedial cleanup project in the third quarter of 2015.

Gross Profit

Total gross profit decreased 12% to $35.2 million for the first quarter of 2016, down from $39.8 million for the first quarter of 2015. Total gross margin was 31% for the first quarter of 2016 compared with 29% for the first quarter of 2015.

Environmental Services

Environmental Services segment gross profit decreased 8% to $30.5 million for the first quarter of 2016, down from $33.2 million for the first quarter of 2015. This decrease primarily reflects lower T&D volumes for the first quarter of 2016 compared to the first quarter of 2015. Total segment gross margin for the first quarter of 2016 was 37% compared with 38% for the first quarter of 2015. T&D gross margin was 41% for the first quarter of 2016 compared with 42% for the first quarter of 2015.

Field & Industrial Services

Field & Industrial Services segment gross profit decreased 29% to $4.8 million for the first quarter of 2016, down from $6.7 million for the first quarter of 2015. Total segment gross margin was 15% for the first quarter of 2016 compared with 14% for the first quarter of 2015. The Allstate business, divested on November 1, 2015, contributed segment gross profit of $2.6 million in the first quarter of 2015.

25

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

Total SG&A decreased to $19.4 million, or 17% of total revenue, for the first quarter of 2016 compared with $24.9 million, or 18% of total revenue, for the first quarter of 2015.

Environmental Services

Environmental Services segment SG&A increased 5% to $5.6 million, or 7% of segment revenue, for the first quarter of 2016 compared with $5.3 million, or 6% of segment revenue, for the first quarter of 2015, primarily reflecting higher bad debt expenses, partially offset by lower incentive compensation in the first quarter of 2016 compared with the first quarter of 2015.

Field & Industrial Services

Field & Industrial Services segment SG&A decreased 60% to $2.5 million, or 8% of segment revenue, for the first quarter of 2016 compared with $6.1 million, or 12% of segment revenue, for the first quarter of 2015. The Allstate business, divested on November 1, 2015, contributed segment SG&A of $3.0 million in the first quarter of 2015. The remaining decrease in segment SG&A primarily reflects lower labor and incentive compensation in the first quarter of 2016 compared with the first quarter of 2015.

Corporate

Corporate SG&A was $11.4 million, or 10% of total revenue, for the first quarter of 2016 compared with $13.5 million, or 10% of total revenue, for the first quarter of 2015, primarily reflecting lower business development expenses and lower incentive compensation in the first quarter of 2016 compared with the first quarter of 2015.

Components of Adjusted EBITDA

Income tax expense

Our effective income tax rate for the first quarter of 2016 was 38.4% compared with 33.1% for the first quarter of 2015. The increase primarily reflects a lower proportion of earnings from our Canadian operations, which are taxed at a lower corporate tax rate, in the first quarter of 2016 compared with the first quarter of 2015. The increase is also partially attributable to a higher U.S. effective tax rate in the first quarter of 2016 driven by a higher overall effective state tax rate resulting from changes in our apportionment between the various states in which we operate.

Interest expense

Interest expense was $4.6 million for the first quarter of 2016 compared with $5.7 million for the first quarter of 2015. The decrease is primarily due to lower debt levels in the first quarter of 2016 compared with the first quarter of 2015. First quarter 2016 interest expense includes $200,000 of incremental non-cash amortization of deferred financing fees associated with debt principal prepayments made during the first quarter of 2016.

Foreign currency gain (loss)

We recognized a $759,000 non-cash foreign currency gain for the first quarter of 2016 compared with a $1.1 million non-cash foreign currency loss for the first quarter of 2015. Foreign currency gains and losses reflect changes in business activity conducted in a currency other than the United States dollar (“USD”), our functional currency. Our Stablex facility is owned by our Canadian subsidiary, whose functional currency is the Canadian dollar (“CAD”). Also, as part of our treasury management strategy, we established intercompany loans between our parent company, US Ecology and Stablex. These intercompany loans are payable by Stablex 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 March 31, 2016, we had $16.1 million of intercompany loans subject to currency revaluation.

Depreciation and amortization of plant and equipment

Depreciation and amortization expense was $5.9 million for the first quarter of 2016 compared with $7.5 million for the first quarter of 2015. The Allstate business, divested on November 1, 2015, contributed depreciation and amortization expense of $899,000 in the first quarter of 2015.

26

Amortization of intangibles

Intangible assets amortization expense was $2.6 million for the first quarter of 2016 compared with $3.3 million for the first quarter of 2015. The Allstate business, divested on November 1, 2015, contributed intangible assets amortization expense of $569,000 in the first quarter of 2015.

Stock-based compensation

Stock-based compensation expense increased 72% to $795,000 for the first quarter of 2016 compared with $463,000 for the first quarter of 2015 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 $1.0 million for the first quarter of 2016 compared with $1.0 million for the first quarter of 2015.

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, 2015.

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 senior secured credit agreement (the “Credit Agreement”). At March 31, 2016, we had $14.3 million in cash and cash equivalents immediately available and $117.3 million of borrowing capacity available under our revolving line of credit (the “Revolving Credit Facility”). 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 Credit Agreement provide additional sources of liquidity should they be required.

Operating Activities

For the three months ended March 31, 2016, net cash provided by operating activities was $30.3 million. This primarily reflects net income of $7.5 million, non-cash depreciation, amortization and accretion of $9.5 million, a decrease in accounts receivable of $12.2 million, an increase in income taxes payable of $3.2 million, a decrease in income taxes receivable of $943,000 and share-based compensation expense of $795,000, partially offset by a decrease in accrued salaries and benefits of $2.1 million and a decrease in deferred revenue of $1.5 million. 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 changes in income taxes payable and receivable are primarily attributable to the timing of income tax payments. The decrease in accrued salaries and benefits is primarily attributable to cash payments during the first quarter of 2016 for accrued 2015 incentive compensation. The decrease in deferred revenue is primarily attributable to the timing of the treatment and disposal of waste received but not yet processed.

Days sales outstanding were 76 days as of March 31, 2016, compared to 68 days as of December 31, 2015 and 82 days as of March 31, 2015. The increase in days sales outstanding compared to December 31, 2015 is primarily attributable to a higher proportion of accounts receivable as a percentage of historically lower first quarter revenues.

For the three months ended March 31, 2015, net cash provided by operating activities was $22.6 million. This primarily reflects net income of $5.9 million, non-cash depreciation, amortization and accretion of $11.8 million, a decrease in accounts receivable of $14.1 million, a decrease in income taxes receivable of $2.2 million, a decrease in other assets of $1.6 million and unrealized foreign currency losses of $1.8 million, partially offset by a decrease in accounts payable and accrued liabilities of $6.3 million, a decrease in deferred revenue of $4.4 million, a decrease in accrued salaries and benefits of $3.3 million and a decrease in deferred income taxes of $1.2 million. Impacts on net income are due to the factors discussed above under “Results of Operations.” Non-cash foreign currency losses reflect a weaker CAD relative to the USD in the first quarter of 2015. The decrease in receivables and deferred revenue is primarily attributable to the timing of the treatment and disposal of waste associated with a significant East Coast remedial clean-up project. The changes in income taxes payable and receivable are primarily attributable to the timing of income tax payments. The decrease in accrued salaries and benefits is primarily attributable to cash payments during 2015 for accrued fiscal year 2014 incentive compensation.

27

Investing Activities

For the three months ended March 31, 2016, net cash used in investing activities was $7.2 million, primarily related to capital expenditures. Significant capital projects included construction of additional disposal capacity at our Blainville, Quebec, Canada and Robstown, Texas locations and equipment purchases and infrastructure upgrades at our corporate and operating facilities.

For the three months ended March 31, 2015, net cash used in investing activities was $9.1 million, primarily related to capital expenditures of $9.2 million primarily for equipment purchases and infrastructure upgrades at our corporate and operating facilities.

Financing Activities

For the three months ended March 31, 2016, net cash used in financing activities was $14.9 million, consisting primarily of $10.8 million of payments on the Company’s term loan and $3.9 million of dividend payments to our stockholders.

For the three months ended March 31, 2015, net cash used in financing activities was $26.0 million, consisting primarily of $22.0 million of payments on the Company’s term loan and $3.9 million of dividend payments to our stockholders.

Credit Facility

On June 17, 2014, in connection with the acquisition of EQ, the Company entered into a new $540.0 million Credit Agreement with a syndicate of banks comprised of a $415.0 million Term Loan with a maturity date of June 17, 2021 and a $125.0 million Revolving Credit Facility with a maturity date of June 17, 2019. Upon entering into the Credit Agreement, the Company terminated its existing credit agreement with Wells Fargo, dated October, 29, 2010, as amended (the “Former Agreement”). Immediately prior to the termination of the Former Agreement, there were no outstanding borrowings under the Former Agreement. No early termination penalties were incurred as a result of the termination of the Former Agreement.

Term Loan

The Term Loan provided an initial commitment amount of $415.0 million, the proceeds of which were used to acquire 100% of the outstanding shares of EQ and pay related transaction fees and expenses. The Term Loan bears interest at a base rate (as defined in the Credit Agreement) plus 2.00% or LIBOR plus 3.00%, at the Company’s option. The Term Loan is subject to amortization in equal quarterly installments in an aggregate annual amount equal to 1.00% of the original principal amount of the Term Loan. At March 31, 2016, the effective interest rate on the Term Loan, including the impact of our interest rate swap, was 4.72%. Interest only payments are due either monthly or on the last day of any interest period, as applicable. As set forth in the Credit Agreement, the Company is required to enter into one or more interest rate hedge agreements in amounts sufficient to fix the interest rate on at least 50% of the principal amount of the $415.0 million Term Loan. In October 2014, the Company entered into an interest rate swap agreement with Wells Fargo, effectively fixing the interest rate on $225.0 million, or 78%, of the Term Loan principal outstanding as of March 31, 2016.

Revolving Credit Facility

The Revolving Credit Facility provides 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 Revolving Credit Facility, revolving 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 EBITDA. The Company is required to pay a commitment fee of 0.50% per annum on the unused portion of the Revolving Credit Facility, with such commitment fee to be reduced based upon the Company’s total leverage ratio as defined in the Credit Agreement. The maximum letter of credit capacity under the Revolving Credit Facility is $50.0 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. Interest only payments are due either monthly or on the last day of any interest period, as applicable. At March 31, 2016, there were no borrowings outstanding on the Revolving Credit Facility. The availability under the Revolving Credit Facility was $117.3 million with $7.7 million of the Revolving

28

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.

For more information about our debt, see Note 9, 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 three months ended March 31, 2016. 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, 2015.

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 March 31, 2016, $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 Credit Agreement. Under the Credit Agreement, Term Loan borrowings incur interest at a base rate (as defined in the Credit Agreement) or LIBOR, at the Company’s option, plus an applicable margin. Revolving loans under the Revolving Credit Facility 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 EBITDA. On October 29, 2014, the Company entered into an interest rate swap agreement with Wells Fargo 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 to Wells Fargo interest at the fixed effective rate of 5.17% and receives from Wells Fargo interest at the variable one-month LIBOR rate on an initial notional amount of $250.0 million.

As of March 31, 2016, there were $290.2 million of borrowings outstanding under the Term Loan and no borrowings outstanding under the Revolving Credit Facility. 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 $290.2 million under our Credit Agreement at March 31, 2016 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 $492,000 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 Stablex subsidiary conducts business in both Canada and the United States. In addition, contracts for services Stablex provides to U.S. customers are generally denominated in USD. During the three months ended March 31, 2016, Stablex transacted approximately 58% of its revenue in USD and at any time has 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.

We established intercompany loans between Stablex and US Ecology, Inc. as part of a tax and treasury management strategy allowing for repayment of third-party bank debt used to complete the acquisition. These intercompany loans are payable using CAD and are subject to mark-to-market adjustments with movements in the CAD. At March 31, 2016, we had $16.1 million of intercompany loans outstanding between Stablex and US Ecology. During the three months ended March 31, 2016, the CAD strengthened as compared to the USD resulting in a $1.0 million 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 March 31, 2016, a $0.01 CAD increase or decrease in currency rate compared to the USD at March 31, 2016 would have generated a gain or loss of approximately $161,000 for the three months ended March 31, 2016.

We had a total pre-tax foreign currency gain of $759,000 for the three months ended March 31, 2016. 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 March 31, 2016. 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 clean-up 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 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 Securities and Exchange Commission (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 this report 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.

EXHIBIT 10

US Ecology, Inc.

Performance Stock Unit Agreement

This Performance Stock Unit Agreement (this “Agreement”) is made and entered into as of January 4, 2016 (the “Grant Date”) by and between US Ecology, Inc., a Delaware corporation (the “Company”), and [           ] (the “Grantee”).

WHEREAS, the Company has adopted the US Ecology, Inc. Omnibus Incentive Plan (the “Plan”) pursuant to which Performance Stock Units may be granted; and

WHEREAS, the Committee has determined that it is in the best interests of the Company and its stockholders to grant the award of Performance Stock Units provided for herein.

NOW, THEREFORE, the parties hereto, intending to be legally bound, agree as follows:

1.     Grant of Performance Stock Units. Pursuant to Section 6.6 of the Plan, the Company hereby grants to the Grantee an Award for a target number of [TARGET NUMBER] Performance Stock Units (the “Target Award”). Each Performance Stock Unit (“PSU”) represents the right to receive, on the settlement date, one Share, subject to the achievement of the applicable Performance Goals and all other terms and conditions set forth in this Agreement and the Plan. The number of PSUs that the Grantee actually earns for the Performance Period (up to a maximum of [MAXIMUM NUMBER]) will be determined by the level of achievement of the Performance Goals in accordance with Section 3. Capitalized terms that are used but not defined herein have the meanings ascribed to them in the Plan.

2.     Performance Period. For purposes of this Agreement, the Performance Period shall be the period commencing on January 1, 2016 and ending on December 31, 2018.

3.     Performance Goals.

3.1     Subject to the Grantee’s continued employment with the Company through the last day of the Performance Period (except as provided below), (i) 50% of the Target Award (the “Peer Group Tranche”) may be earned based on the Company’s total shareholder return (“TSR”) for the Performance Period relative to that of the members of the peer group of companies set forth on Exhibit I (the “Peer Group”) and (ii) 50% of the Target Award (the “S&P Tranche”) may be earned based on the Company’s TSR for the Performance Period relative to that of the companies in the S&P 600 small cap index as of the first day of the Performance Period.  The number of PSUs actually earned from the Peer Group Tranche and the S&P Tranche will be determined at the end of the Performance Period based on the Company’s TSR for the Performance Period relative to the applicable index as follows:

TSR Percentile Relative to Index	Percentage of Target Award Earned
Below 35th	0%
35th	50%
50th	100%
90th or above	200%

1

For achievement by the Company of a TSR at a percentile between the percentiles set forth above, the number of PSUs actually earned will be determined using linear interpolation.  TSR will be calculated assuming that dividends paid during the Performance Period by a member of the applicable index are immediately reinvested in shares of the company paying such dividend.  TSR as of any date will be calculated based on the average closing price of the common stock of each member of the applicable index for the 20 consecutive trading days immediately preceding such date.  Any company whose stock ceases to be publicly traded or whose TSR cannot otherwise be determined, in each case, for any reason shall be removed from the applicable index and any calculations made hereunder shall be revised to reflect the removal of such entity from such index.  All determinations as to whether the applicable Performance Goals have been achieved and at what levels, the number of PSUs earned by the Grantee, and all other matters related to this Section 3 shall be made by the Committee in its sole discretion.

3.2     Any PSUs earned for the Performance Period shall be settled in accordance with the Plan within 30 days after the expiration or earlier termination of the Performance Period.

4.     Termination of Service.  Unless otherwise provided in an effective employment, consulting, severance or similar agreement with the Company or a Subsidiary, or as otherwise may be determined by the Committee, (i) upon a the Grantee’s termination of employment with the Company (A) at any time, due to the Grantee’s death or Disability or (B) within 24 months following a Change in Control, by the Company or a Subsidiary without Cause or by the Grantee for Good Reason, the unvested portion of the PSUs shall vest in full (with the applicable Performance Goals being deemed to have been achieved at target or, if greater, actual levels), the Performance Period shall terminate and the PSUs shall be settled in accordance with Section 3.2 and (ii) upon the Grantee’s termination of employment with the Company for any other reason, the unvested portion of the PSUs shall be forfeited with no compensation due the Grantee.

5.     Transferability.  Except as permitted by the Committee in accordance with Section 13 of the Plan, no PSU or other right or interest of the Grantee hereunder shall be pledged, encumbered, or hypothecated to, or in favor of, or subject to any lien, obligation, or liability of the Grantee to, any party, other than the Company or any Subsidiary, or assigned or transferred by the Grantee otherwise than by will or the laws of descent and distribution, and all rights hereunder shall be exercisable during the lifetime of the Grantee only by the Grantee or his or her guardian or legal representative.

6.     Stockholder Rights.  Nothing contained in this Agreement shall be construed to give the Grantee any rights as a stockholder with respect to any Shares underlying the PSUs (including, without limitation, any voting, dividend or derivative or other similar rights) unless and until such Shares are issued to the Grantee upon the settlement of the PSUs.

7.     No Right to Continued Service. Neither the Plan nor this Agreement shall be construed as giving the Grantee any right to be retained in the employ or service of the Company or any Subsidiary.

8.     Taxes.  The Grantee must make appropriate arrangements for the payment of any taxes relating to the PSUs granted hereunder. The Company is authorized to withhold from any payment relating to the PSUs, including from a distribution of Shares or any payroll or other payment to the Grantee, amounts of withholding and other taxes due in connection with the PSUs, and to take such other action as the Committee may deem advisable to enable the Company and the Grantee to satisfy obligations for the payment of withholding taxes and other tax obligations relating to the PSUs. This authority shall include the ability to withhold or receive Shares or other property and to make cash payments in respect thereof in satisfaction of the Grantee’s tax obligations and to require the Grantee to enter into elections in respect of taxes. Withholding of taxes in the form of Shares shall not occur at a rate that exceeds the minimum required statutory federal and state withholding rates. If the Grantee is subject to the reporting requirements of Section 16 of the Exchange Act, the Grantee shall have the right to pay all or a portion of any withholding or other taxes due in connection with the PSUs by directing the Company to withhold Shares that would otherwise be received in connection with the PSUs up to the minimum required withholding amount.

2

9.     Compliance with Securities Law.

9.1     No Shares may be issued hereunder if the Company shall at any time determine that to do so would (i) violate the listing requirements of an applicable securities exchange, or adversely affect the registration or qualification of the Company’s Shares under any state or federal law or regulation, or (ii) require the consent or approval of any regulatory body or the satisfaction of withholding tax or other withholding liabilities. In any of the events referred to in clause (i) or clause (ii) above, the issuance of such Shares shall be suspended and shall not be effective unless and until such withholding, listing, registration, qualifications or approval shall have been effected or obtained free of any conditions not acceptable to the Company in its sole discretion, notwithstanding any termination of the Award or any portion of the Award during the period when issuance has been suspended.

9.2     The Committee may require, as a condition to the issuance of Shares hereunder, representations, warranties and agreements to the effect that such Shares are being purchased or acquired by the Grantee for investment only and without any present intention to sell or otherwise distribute such Shares and that the Grantee will not dispose of such Shares in transactions which, in the opinion of counsel to the Company, would violate the registration provisions of the Securities Act and the rules and regulations thereunder.

10.  Governing Law. To the extent that Federal laws do not otherwise control, the validity and construction of this shall be construed and enforced in accordance with the laws of the State of Delaware, but without giving effect to the choice of law principles thereof.

11.  Recoupment.  This Award shall be subject to mandatory repayment by the Grantee to the Company pursuant to the terms of any applicable Company “clawback” or recoupment policy.

12.  PSUs Subject to Plan. This Agreement is subject to the Plan as approved by the Company’s stockholders. The terms and provisions of the Plan as it may be amended from time to time are hereby incorporated herein by reference. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan, the applicable terms and provisions of the Plan will govern and prevail.

13.  Successors and Assigns. The Company may assign any of its rights under this Agreement. This Agreement will be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this Agreement will be binding upon the Grantee and the Grantee’s beneficiaries, executors, administrators and the person(s) to whom the PSUs may be transferred by will or the laws of descent or distribution.

14.  Amendment. The Committee may waive any conditions or rights under, or amend, alter, suspend, discontinue, or terminate, this Agreement; provided, however, that without the consent of the Grantee, no such amendment, alteration, suspension, discontinuation, or termination of this Agreement may materially and adversely affect the rights of the Grantee under this Agreement, except insofar as any such action is necessary to ensure the Agreement’s compliance with applicable law or regulation or the listing requirements of an applicable securities exchange, including, without limitation, Code Section 409A.

15.  Section 409A. This Agreement is intended to comply with, or be exempt from, Code Section 409A and all regulations, guidance, compliance programs and other interpretative authority thereunder, and all provisions of this Agreement shall be applied and interpreted in a manner consistent therewith. Notwithstanding anything contained herein to the contrary, in the event the Award is subject to Code Section 409A, the Committee may, in its sole discretion and without the Grantee’s prior consent, amend this Agreement or take any other actions as deemed appropriate by the Committee to (i) exempt this Agreement from the application of Code Section 409A, (ii) preserve the intended tax treatment of the Award or (iii) comply with the requirements of Code Section 409A. In the event that the Grantee is a “specified employee” within the meaning of Code Section 409A, and a payment or benefit provided for under this Agreement would be subject to additional tax under Code Section 409A if such payment or benefit is paid within six (6) months after the Grantee’s separation from service (within the meaning of Code Section 409A), then such payment or benefit shall not be paid (or commence) during the six (6) month period immediately following the Grantee’s separation from service except as provided in the immediately following sentence. In such an event, any payments or benefits that would otherwise have been made or provided during such six (6) month period and which would have incurred such additional tax under Code Section 409A shall instead be paid to the Grantee in a lump-sum cash payment, without interest, on the earlier of (i) the first business day of the seventh month

3

following the Grantee’s separation from service or (ii) the tenth business day following the Grantee’s death. Notwithstanding the foregoing, none of the Company, its Affiliates or their respective directors, officers, employees or advisors will be held liable for any taxes, interest or other amounts owed by the Grantee as a result of the application of Code Section 409A.

16.  Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original but all of which together will constitute one and the same instrument. Counterpart signature pages to this Agreement transmitted by facsimile transmission, by electronic mail in portable document format (.pdf), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing an original signature.

17.  Acceptance. The Grantee hereby acknowledges receipt of a copy of the Plan and this Agreement. The Grantee has read and understands the terms and provisions hereof and thereof, and accepts the PSUs subject to all of the terms and conditions of the Plan and this Agreement. The Grantee acknowledges that there may be adverse tax consequences upon the vesting or settlement of the PSUs or disposition of the underlying shares and that the Grantee has been advised to consult a tax advisor prior to such vesting, settlement or disposition.

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, 2015. The results of operations for the three months ended March 31, 2016 are not necessarily indicative of the results to be expected for the entire year ending December 31, 2016. For comparative purposes, certain amounts in prior periods’ consolidated financial statements have been reclassified to conform to the current period presentation.

On November 1, 2015, we sold our Allstate Power Vac, Inc. (“Allstate”) subsidiary to a private investor group. See Note 2 for additional information.

The Company’s consolidated balance sheet as of December 31, 2015 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 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 March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718). This ASU was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. The update is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. We are assessing the impact the adoption of ASU 2016-09 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. We are currently assessing the impact the adoption of ASU 2014-09 may have on our consolidated financial position, results of operations and cash flows.

DIVESTITURE

NOTE 2.DIVESTITURE

On November 1, 2015, we completed the divestiture of Allstate for cash proceeds at closing of $58.8 million. For the year ended December 31, 2015, we recognized a pre-tax loss on the divestiture of Allstate, including transaction-related costs, of $542,000, which was included in Other income (expense) in our consolidated statements of operations. Prior to the divesture, Allstate represented the majority of the industrial services business included in our Field & Industrial Services segment. The sale of Allstate did not meet the requirements to be reported as a discontinued operation as defined in ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. See Note 5 to the Consolidated Financial Statements in “Part II, Item 8. Financial Statements and Supplementary Data” of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 for additional information.

No post-closing adjustments were recorded during the three months ended March 31, 2016. On April 25, 2016, we received additional cash proceeds of $827,000 in settlement of final post-closing adjustments, resulting in a pre-tax gain to be recognized in the second quarter of 2016.

Amounts relate to our 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 debt are made. Amounts in AOCI expected to be recognized in interest expense over the next 12 months total approximately $3.3 million ($2.1 million after tax).

Major Customers

No customer accounted for more than 10% of total revenue for the three months ended March 31, 2016 or 2015. No customer accounted for more than 10% of total trade receivables as of March 31, 2016 or December 31, 2015.

Credit Risk Concentration

We maintain most of our cash and cash equivalents with nationally recognized financial institutions like Wells Fargo Bank, National Association (“Wells Fargo”) and Comerica, Inc. 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.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

NOTE 6.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 March 31, 2016, the fair value of the Company’s variable-rate debt was estimated to be $289.0 million.

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.

(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 long-term liabilities in the Company’s consolidated balance sheet as of March 31, 2016 and December 31, 2015.

On June 17, 2014, in connection with the acquisition of EQ Holdings, Inc. and its wholly-owned subsidiaries (collectively “EQ”), the Company entered into a new $540.0 million senior secured credit agreement (the “Credit Agreement”) with a syndicate of banks comprised of a $415.0 million term loan (the “Term Loan”) with a maturity date of June 17, 2021 and a $125.0 million revolving line of credit (the “Revolving Credit Facility”) with a maturity date of June 17, 2019. Upon entering into the Credit Agreement, the Company terminated its existing credit agreement with Wells Fargo, dated October 29, 2010, as amended (the “Former Agreement”). Immediately prior to the termination of the Former Agreement, there were no outstanding borrowings under the Former Agreement. No early termination penalties were incurred as a result of the termination of the Former Agreement.

Term Loan

The Term Loan provided an initial commitment amount of $415.0 million, the proceeds of which were used to acquire 100% of the outstanding shares of EQ and pay related transaction fees and expenses. The Term Loan bears interest at a base rate (as defined in the Credit Agreement) plus 2.00% or LIBOR plus 3.00%, at the Company’s option. The Term Loan is subject to amortization in equal quarterly installments in an aggregate annual amount equal to 1.00% of the original principal amount of the Term Loan. At March 31, 2016, the effective interest rate on the Term Loan, including the impact of our interest rate swap, was 4.72%. Interest only payments are due either monthly or on the last day of any interest period, as applicable. As set forth in the Credit Agreement, the Company is required to enter into one or more interest rate hedge agreements in amounts sufficient to fix the interest rate on at least 50% of the principal amount of the $415.0 million Term Loan. In October 2014, the Company entered into an interest rate swap agreement with Wells Fargo, effectively fixing the interest rate on $225.0 million, or 78%, of the Term Loan principal outstanding as of March 31, 2016.

Revolving Credit Facility

The Revolving Credit Facility provides 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 Revolving Credit Facility, revolving 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 earnings before interest, taxes, depreciation and amortization (“EBITDA”). The Company is required to pay a commitment fee of 0.50% per annum on the unused portion of the Revolving Credit Facility, with such commitment fee to be reduced based upon the Company’s total leverage ratio as defined in the Credit Agreement. The maximum letter of credit capacity under the Revolving Credit Facility is $50.0 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. Interest only payments are due either monthly or on the last day of any interest period, as applicable. At March 31, 2016, there were no borrowings outstanding on the Revolving Credit Facility. As of March 31, 2016, the availability under the Revolving Credit Facility was $117.3 million with $7.7 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.

Except as set forth below, the Company may prepay the Term Loan or permanently reduce the Revolving Credit Facility commitment under the Credit Agreement at any time without premium or penalty (other than customary “breakage” costs with respect to the early termination of LIBOR loans). Subject to certain exceptions, the Credit Agreement provides for mandatory prepayment upon certain asset dispositions, casualty events and issuances of indebtedness. The Credit Agreement is also subject to mandatory annual prepayments commencing in December 2015 if our total leverage (defined as the ratio of our consolidated funded debt as of the last day of the applicable fiscal year to our adjusted EBITDA for such period) exceeds certain ratios as follows: 50% of our adjusted excess cash flow (as defined in the Credit Agreement and which takes into account certain adjustments) if our total leverage ratio is greater than 2.50 to 1.00, with step-downs to 0% if our total leverage ratio is equal to or less than 2.50 to 1.00.

Pursuant to (i) an unconditional guarantee agreement (the “Guarantee”) and (ii) a collateral agreement, each entered into by the Company and its domestic subsidiaries on June 17, 2014, the Company’s obligations under the Credit Agreement are 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 the Credit Agreement is secured by substantially all of the Company’s and its domestic subsidiaries’ assets except the Company’s and its domestic subsidiaries’ real property.

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. We may only declare quarterly or annual dividends if on the date of declaration, no event of default has occurred and no other event or condition has occurred that would constitute default due to the payment of the dividend.

The Credit Agreement also contains a financial maintenance covenant, which is a maximum Consolidated Senior Secured Leverage Ratio, as defined in the Credit Agreement, and is only applicable to the Revolving Credit Facility. Our Consolidated Senior Secured Leverage Ratio as of the last day of any fiscal quarter, commencing with June 30, 2014, may not exceed the ratios indicated below:

Fiscal Quarters Ending	Maximum Ratio
December 31, 2015 through September 30, 2016	3.75 to 1.00
December 31, 2016 through September 30, 2017	3.50 to 1.00
December 31, 2017 through September 30, 2018	3.25 to 1.00
December 31, 2018 and thereafter	3.00 to 1.00

At March 31, 2016, we were in compliance with all of the financial covenants in the Credit Agreement.

CLOSURE AND POST-CLOSURE OBLIGATIONS

CLOSURE AND POST-CLOSURE OBLIGATIONS

NOTE 10.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.

INCOME TAXES

NOTE 11.INCOME TAXES

Our effective tax rate for the three months ended March 31, 2016 was 38.4%, up from 33.1% for the three months ended March 31, 2015. The increase for the three months ended March 31, 2016 primarily reflects a lower proportion of earnings from our Canadian operations, which are taxed at a lower corporate tax rate, for the three months ended March 31, 2016 compared with the three months ended March 31, 2015. The increase is also partially attributable to a higher U.S. effective tax rate for the three months ended March 31, 2016 which is primarily driven by a higher overall effective state tax rate resulting from changes in our apportionment between the various states in which we operate.

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. During the three months ended March 31, 2016, the US Ecology, Inc. IRS examination for the 2012 tax year concluded with no material changes. US Ecology, Inc. is subject to examination by the IRS for tax years 2013 through 2015. EQ is currently under IRS examination for the 2012 tax year and also remains subject to examination by the IRS for tax years 2013 through 2015. The Company is indemnified by the previous owners of EQ for any pre-acquisition tax liabilities. We may be subject to examinations by the Canada Revenue Agency as well as various state and local taxing jurisdictions for tax years 2011 through 2015. We are currently not aware of any other examinations by taxing authorities.

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”), and 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 March 31, 2016, 1,249,752 shares of common stock remain available for grant under the Omnibus Plan.

PSUs, RSUs and Restricted Stock

On January 4, 2016, the Company granted 16,000 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, 2016, 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 $41.22 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 2016 and 2015 are as follows:

	2016			2015
Stock price on grant date	$	35.05		$	46.89
Expected term (years)	3.0			2.6
Expected volatility	29		%	29		%
Risk-free interest rate	1.3		%	0.9		%

OPERATING SEGMENTS

OPERATING SEGMENTS

NOTE 15.   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.

Effective January 1, 2016, we changed our internal reporting structure by moving the financial results of our Sulligent, Alabama and Tampa, Florida locations from our Environmental Services segment to our Field & Industrial Services segment. The purpose of this change is to align our internal reporting structure with how we manage our business based on the primary service offering of each location. Throughout this Quarterly Report on Form 10-Q, our segment results for all periods presented have been recast to reflect this change.

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, which are not considered part of usual business operations. 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.

A reconciliation of Adjusted EBITDA to Net Income is as follows:

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, 2015. The results of operations for the three months ended March 31, 2016 are not necessarily indicative of the results to be expected for the entire year ending December 31, 2016. For comparative purposes, certain amounts in prior periods’ consolidated financial statements have been reclassified to conform to the current period presentation.

On November 1, 2015, we sold our Allstate Power Vac, Inc. (“Allstate”) subsidiary to a private investor group. See Note 2 for additional information.

The Company’s consolidated balance sheet as of December 31, 2015 has been derived from the Company’s audited consolidated balance sheet as of that date.

Use of Estimates

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 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

Recently Issued Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718). This ASU was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. The update is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. We are assessing the impact the adoption of ASU 2016-09 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. We are currently assessing the impact the adoption of ASU 2014-09 may have on our consolidated financial position, results of operations and cash flows.

(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.

(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 long-term liabilities in the Company’s consolidated balance sheet as of March 31, 2016 and December 31, 2015.
