Item 8.01. Other Events


As previously announced, on February 8, 2022, US Ecology, Inc., a Delaware
corporation ("US Ecology" or the "Company"), Republic Services, Inc., a Delaware
corporation ("Republic Services"), and Bronco Acquisition Corp., a Delaware
corporation and a wholly-owned subsidiary of Republic Services ("Merger Sub"),
entered into Agreement and Plan of Merger (as the same may be amended,
supplemented and modified from time to time, the "Merger Agreement"), which
provides that, subject to the conditions set forth in the Merger Agreement,
Merger Sub will merge with and into US Ecology, with US Ecology continuing as
the surviving company and a wholly-owned subsidiary of Republic Services (such
transactions, collectively, the "Merger").

One of the conditions to the Merger under the Merger Agreement is the approval
of US Ecology's stockholders. On March 11, 2022, in accordance with the rules
and regulations of the SEC, US Ecology filed a Preliminary Proxy Statement on
Schedule 14A (the "Preliminary Proxy Statement") with the U.S. Securities and
Exchange Commission (the "SEC") in order to solicit proxies in connection with
an upcoming special meeting of US Ecology's stockholders to approve the Merger
Agreement (the "Special Meeting"). US Ecology subsequently filed, and commenced
mailing with respect to, a Definitive Proxy Statement on Schedule 14A
(the "Definitive Proxy Statement" and, together with the Preliminary Proxy
Statement, the "Proxy Statement") with the SEC on March 29, 2022.

Commencing on March 15, 2022, purported individual stockholders of US Ecology
filed complaints in the United States District Courts for the Southern District
of New York, for the Eastern District of New York, and for the Eastern District
of Pennsylvania, in the matters captioned Ryan O'Dell v. US Ecology, Inc., et
al, No. 22-cv-2131 (S.D.N.Y., filed Mar. 15, 2022) ("O'Dell"), Ray Pizzaro v. US
Ecology, Inc., et al, No. 22-cv-02144 (S.D.N.Y., filed Mar. 15, 2022)
("Pizzaro"), Matthew Whitfield v. US Ecology, Inc., et al, No. 22-cv-01515
(E.D.N.Y., filed Mar. 18, 2022) ("Whitfield"), Lewis D. Baker v. US Ecology,
Inc., et al, No. 22-cv-01053 (E.D. Pa., filed Mar. 18, 2022) ("Baker"), and
Teresa McCurdy v. US Ecology, Inc. et al, No. 22-cv-01685 (E.D.N.Y., filed Mar.
25, 2022) ("McCurdy," and together, the "Transaction Litigation"). The
complaints in the Transaction Litigation name as defendants the Company and the
members of the Board.

The complaints in the Transaction Litigation generally allege that the
preliminary proxy statement filed by US Ecology with the SEC on March 11, 2022,
in connection with the Merger Agreement is materially incomplete and misleading
by allegedly failing to disclose purportedly material information relating to
the sale process leading to the proposed transaction, the Company's financial
projections, and the analyses performed by the Co-Financial Advisors. Each of
the Complaints asserts violations of Section 14(a) of the Exchange Act, Rule
14a-9 promulgated thereunder, and Section 20(a) of the Exchange Act. In
addition, the complaint in the Pizzaro action also asserts a claim for breach of
fiduciary duty by the members of the Board in connection with the approval of
the Merger Agreement and the disclosures in the preliminary proxy statement, and
a claim against US Ecology for aiding and abetting the alleged breaches of
fiduciary duty. The Transaction Litigation seeks, among other things, an
injunction of the proposed transaction, rescission of the Merger Agreement, a
declaratory judgment that the Company and the Board violated the Exchange Act
and Rule 14a-9 promulgated thereunder, damages, plaintiff's attorneys' fees and
expenses, and any other relief the court may deem just and proper.

While US Ecology cannot predict the outcome of each Transaction Litigation, US Ecology believes that the cases are without merit and US Ecology and its directors intend to defend vigorously against the Transaction Litigation.

It is possible that additional similar complaints could be filed in connection with the proposed transaction. If additional similar complaints are filed, absent new or significantly different allegations, US Ecology will not necessarily disclose such additional complaints or filings.


In addition to the Transaction Litigation, the Company has received letters from
four purported stockholders of the Company demanding additional disclosures
related to the sale process leading to the proposed transaction, the Company's
financial projections and the analyses performed by the Co-Financial Advisors.







SUPPLEMENTAL DISCLOSURES

Without admitting in any way that the disclosures below are material or otherwise required by law, the Company makes the following amended and supplemental disclosures.


The following disclosures supplement the disclosures contained in the Proxy
Statement and should be read in conjunction with the disclosures contained in
the Proxy Statement, which should be read in its entirety. To the extent that
the information set forth herein differs from or updates information contained
in the Proxy Statement, the information set forth herein shall supersede or
supplement the information in the Proxy Statement. All page references are to
pages in the Definitive Proxy Statement, and terms used in this Current Report
on Form 8-K, unless otherwise defined, have the meanings set forth in the
Definitive Proxy Statement. For clarity, new text within restated disclosure
from the Definitive Proxy Statement is presented in underlined text.

The section of the Definitive Proxy Statement entitled: "Background of Merger" is amended and supplemented as follows:

On page 30, the third full paragraph is amended and restated in its entirety as follows (new language underlined):



Meanwhile, the Company began to receive inbound indications of interest from
potential transaction counterparties: On December 11, 2020, Party A, a private
equity firm, delivered an unsolicited letter expressing an interest in acquiring
100% of the Company's common stock at a value of $46.60 per share, and on
December 14, 2020, Party B, a strategic buyer, delivered an unsolicited letter
expressing an interest in acquiring 100% of the Company's common stock at a
value range of $44.00-$46.00 per share.

On page 30, the fourth full paragraph is amended and restated in its entirety as follows (new language underlined):



In light of the inbound inquiries the Company had received regarding a potential
strategic transaction, the Company engaged both Houlihan Lokey and Barclays, to
provide financial advisory services in connection with any such strategic
transaction, including, in each case and if requested by the Company, the
delivery by Barclays or Houlihan Lokey (as applicable) of an opinion to the
Board with respect to the fairness, from a financial point of view, to the
Company's stockholders of the consideration to be offered in a particular
strategic transaction to such stockholders. Barclays and Houlihan Lokey were
retained as Co-Financial Advisors to the Company in connection with a potential
strategic transaction involving the Company based on various factors, including
each Co-Financial Advisor's industry expertise, qualifications and reputation
with respect to financial advisory services and the Board's determination that
retaining two experienced financial advisors would be in the best interests of
US Ecology's stockholders.

On page 31, the fourth full paragraph is amended and restated in its entirety as follows (new language underlined):



On August 31, 2021, Party D's Executive Chairman and the Company's Chief
Executive Officer held a discussion at an industry event during which Party D, a
strategic buyer, disclosed receiving an unsolicited inbound communication from
Party C presenting Party C's investment thesis on the Company and inquiring if
Party D would have any interest in pursuing an acquisition of the Company. In

Party D would not have an interest in pursuing a transaction with the Company.
The Company's Chief Executive Officer later reported this communication to

the
Board.

On September 7, 2021, the Chief Executive Officer of Party B contacted the
Company's Chief Executive Officer to discuss current industry trends and
business challenges. During this discussion, Party B expressed continued
interest in pursuing a transaction with the Company, but noted that Party B
would likely need to pay a significant portion of the transaction consideration
using its stock instead of cash, given Party B's recent announcement of another
transaction. The Company's Chief Executive Officer later reported this
communication to the Board.

On page 32, the first full paragraph is amended and restated in its entirety as follows (new language underlined):



On October 22, 2021, the Chief Development Officer of Republic Services
contacted one of the Company's independent directors, Richard Burke, to inquire
who Republic Services should contact to initiate a discussion regarding
exploring a strategic transaction. The Chief Development Officer of Republic
Services was a prior industry contact of Mr. Burke. Following this unsolicited
outreach, Mr. Burke directed that the proper channel of communication be through
the Company's Chief Executive Officer, and on October 23, 2021, the respective
Chief Executive Officers of the Company and Republic Services discussed, among
other things, an overview of the Company's businesses, as well as the possible
synergies that could result from an acquisition of the Company by Republic
Services. The Company's Chief Executive Officer then communicated the content of
the discussion to the Board by email on October 23, 2021.

On page 32, the sixth full paragraph is amended and restated in its entirety as follows (new language underlined):


On November 16, 2021, the Company had an introductory meeting with Party E, a
private equity firm, another party which had expressed an interest
(unsolicited)in a potential transaction with the Company, to provide an overview
of the Company's business.

On page 33, the first full paragraph is amended and restated in its entirety as follows (new language underlined):



On November 29, 2021, following the initial discussions with Party E, the Board
met and discussed Party E's indication of interest. The Board authorized
management to negotiate a nondisclosure agreement with Party E, but only on a
non-exclusive basis because the Company was at that time in active discussions
with other parties. At this meeting of the Board, the Board also established a
transaction committee to oversee the Company's exploration of potential
strategic alternatives, including, but not limited to, a potential transaction
with Republic Services, Party E or any other interested party. The members of
the committee were each "independent" under applicable Nasdaq listing standards,
had no financial or other material relationships with any potential counterparty
and were each selected by the Board based on their deep experience with merger
and acquisition transactions. The transaction committee ("Transaction
Committee") was comprised of Daniel Fox, Richard Burke, Katina Dorton, and Glenn
A. Einsenburg, with Richard Burke as chairman, and the goal of the Transaction
Committee was to allow the Board to expeditiously and efficiently explore a
potential merger or sale of, or other strategic transaction involving, the
Company, to keep the Board fully informed and ultimately make a recommendation
regarding any such transaction to the full Board. The Transaction Committee was
not established due to any conflict of interest with any potential counterparty.
At this meeting representatives of Dechert also made a preliminary report to the
Board on their views of the potential antitrust risks that would arise in
attempting to complete a transaction with various proposed counterparties,
including Republic Services, Party A, Party B and Party E.

On page 33, the sixth full paragraph is amended and restated in its entirety as follows (new language underlined):

a negotiated transaction. In response, on December 8, 2021, at the direction of
the Transaction Committee and in consultation with the Company's Co-Financial
Advisors,the Company's Chief Executive Officer contacted Republic Services'
Chief Development Officer and expressed the view that, based on prior
discussions with the Board, Republic Services would need to increase the
valuation range stated in Republic Services' November 3, 2021 offer to a price
of $50.00 per share or more in order for the Company to seriously entertain
Republic Services' offer.

On page 34, the last sentence of the first full paragraph is amended and restated in its entirety as follows (new language underlined):



The Transaction Committee also reviewed the Company's financial projections,
which are the same Projections described and set forth on pages 58 to 61 of this

On page 35, the first full paragraph is amended and restated in its entirety as follows (new language underlined):



On January 11, 2022, the Company and Republic Services executed a nondisclosure
agreement, which, among other things, included a nine-month standstill
obligation in favor of the Company which would fall away upon the announcement
by the Company of the Company's entry into a definitive agreement with respect
to a strategic transaction with a party other than Republic Services. Other than
Party E and Republic Services, the Company did not enter into any other

On page 48, the second paragraph under the disclosure entitled "Discounted Cash
Flow Analysis" is amended and restated in its entirety as follows (new language
is underlined):

Barclays first calculated the estimated enterprise value of the Company using
the discounted cash flow method, Barclays added (i) the Company's projected
after-tax unlevered free cash flows for fiscal years 2022 through 2026, based on
management projections, to (ii) the "terminal value" of the Company and any tax
savings from the use of net operating losses, and discounted such amount to its
present value using a range of selected discount rates. The utilization of net
operating losses used by Barclays in this analysis is defined and set forth in
the section of this Proxy Statement titled "Projected Financial Information" on
pages 58 to 61. The after-tax unlevered free cash flows were calculated by
taking the Adjusted EBITDA of the Company and (i) subtracting cash expenses,
cash taxes and capital expenditures and (ii) adjusting for changes in working
capital, in each case based on the management projections. The after-tax
unlevered free cash flows used by Barclays in this analysis are defined and set
forth in the section of this Proxy Statement titled "Projected Financial
Information" on pages 58 to 61. The residual value of the Company at the end of
the forecast period, or "terminal value," was estimated by selecting a range of
perpetuity growth rates of 2.0% to 3.0%, which were derived by Barclays
utilizing its professional judgment and experience. The range of after-tax
discount rates of 8.5% to 9.5% was selected based on an analysis of the weighted
average cost of capital of the Company, which was derived by application of the
Capital Asset Pricing Model and took into account certain metrics including the
unlevered beta of the Company and the capital structures of the selected
comparable companies.

On page 49, the third full paragraph under the section entitled: "Present Value of Future Share Price Analysis" is amended and restated in its entirety as follows (new language is underlined):



Barclays then calculated a range of implied prices per share of Company common
stock by (i) subtracting the projected amount of the Company's net debt as of
each respective fiscal year end based on management projections, (ii) adding to
such amount estimated future investments of approximately $12 million by the
Company in a privately-held company, (iii) dividing such amount by the estimated
fully diluted number of shares of Company common stock derived from management
projections and (iv) adding to such future equity values per share of Company
common stock the anticipated amount of annual dividends per share of Company
common stock, as applicable, based on the management projections. The annual
dividends and fully diluted number of shares for each fiscal year used in
Barclays' analysis are defined and set forth in the section of this Proxy
Statement titled "Projected Financial Information" on pages 58 to 61.

The section of the Definitive Proxy Statement entitled: "Opinions of Financial Advisors - Opinion and Financial Analysis of Houlihan Lokey" is amended and supplemented as follows:

On page 55, the second sentence of the paragraph entitled: "Enterprise" is amended and restated in its entirety as follows (new language is underlined):




Enterprise. Houlihan Lokey performed a discounted cash flow analysis of the
Company on an enterprise basis by calculating the estimated net present value of
the projected unlevered, after-tax free cash flows of the Company and the
estimated net present value of the terminal value of the Company, based on the
Projections, in each case, including the Company's ROI Initiatives that are
forecasted to be started in fiscal year 2022 and excluding net cash flows from
the Company's ROI Initiatives that are forecasted to be started in fiscal year
2023 or fiscal year 2024; for further information, please refer to "Unlevered
Free Cash Flow (Enterprise)" in the section of this Proxy Statement entitled
"Projected Financial Information" beginning on page 58. Houlihan Lokey
calculated terminal values for the Company by applying a range of perpetuity
growth rates of 2.5% to 3.0%, selected based on Houlihan Lokey's professional
judgment and experience, to the Company's fiscal year 2026 estimated unlevered,
after-tax free cash flows. The net present values of the Company's projected
future cash flows and terminal values were then calculated using discount rates
ranging from 8.5% to 9.5%, based on an estimate of the Company's weighted
average cost of capital, to determine an implied enterprise value reference
range.

On page 55, the second sentence of the subsection entitled: "ROI Initiatives" is amended and restated in its entirety as follows (new language is underlined):



ROI Initiatives. Houlihan Lokey performed a discounted cash flow analysis of the
Company's ROI Initiatives by calculating the estimated net present value of the
projected unlevered, after-tax free cash flows of the Company's ROI Initiatives
that are forecasted to be started in fiscal year 2023 or fiscal year 2024 and
the estimated net present value of the terminal value of such ROI Initiatives,
based on the Projections (the "ROI Initiatives Implied Value"); for further
information, please refer to "Unlevered Free Cash Flow (ROI)" in the section of
this Proxy Statement entitled "Projected Financial Information" beginning on
page 58. Houlihan Lokey calculated terminal values for such ROI Initiatives by
applying a range of perpetuity growth rates of 2.5% to 3.0%, selected based on
Houlihan Lokey's professional judgment and experience, to such ROI Initiatives'
fiscal year 2026 normalized unlevered, after-tax free cash flows. The net
present values of such ROI Initiatives' projected future cash flows and terminal
values were then calculated using discount rates ranging from 11.0% to 12.0%,
based on an estimate of the cost of equity of (i) the Company and (ii) the
selected companies listed below, to determine an implied value.

On page 55, the second full paragraph of the subsection entitled: "ROI Initiatives" is amended and restated in its entirety as follows (new language is underlined):


Houlihan Lokey then added the implied enterprise value reference range from the
discounted cash flow analysis of the Company on an enterprise basis and the ROI
Initiatives Implied Value, to determine a total implied enterprise value
reference range for the Company. Houlihan Lokey then subtracted total debt and
added cash and cash equivalents, the book value of the Company's long-term
investments, as provided by Company management and each as of December 31, 2021,
and the present value of the expected tax savings from the Company's net
operating losses, as provided by Company management (calculated assuming a
federal tax rate of 21.0% and using a discount rate range of 11.0% to 12.0%,
based on an estimate of the Company's cost of equity), to derive an implied
equity value reference range for the Company. The Company's cash and cash
equivalents as of December 31, 2021, and the utilization of net operating losses
of the Company are set forth in the section of this Proxy Statement titled
"Projected Financial Information" on pages 58 to 61. The figures in the implied
equity value reference range were then divided by the number of fully diluted
shares of US Ecology common stock outstanding to calculate a reference range of
implied equity values per share. The discounted cash flow analysis indicated an
implied per share equity value reference range of $43.64-$60.63, as compared to
the proposed merger consideration of $48.00 per share in cash.

On pages 55 - 56, the disclosure that begins with "The selected companies
included the following:" and ends with "Selected Companies Analysis" is amended

Taking into account the results of the selected companies analysis and based on
its professional judgment and experience, Houlihan Lokey applied the selected
multiple ranges set forth in the table below to corresponding financial data for
the Company based on the Projections, to calculate an implied enterprise value
reference range. Houlihan Lokey then subtracted total debt and added cash and
cash equivalents, the book value of the Company's long-term investments, as
provided by Company management, with balance sheet information as of December
31, 2021, and the ROI Initiatives Implied Value, to derive an implied equity
value reference range. The figures in the implied equity value reference range
were then divided by the number of fully diluted shares of US Ecology common
stock outstanding to calculate a reference range of implied values per share.
The selected companies analysis indicated the implied per share equity value
reference ranges set forth in the table below, as compared to the proposed
merger consideration of $48.00 per share in cash.
