Enviri (NVRI) 8-K Harsco Announces Launch of Private Offering of $500 Million of

Exhibit 99.3

UNAUDITED PRO FORMA FINANCIAL STATEMENTS

On May 8, 2019, we, solely in our capacity as guarantor to the Acquisition, and CH LLC, entered into a stock purchase agreement with Clean Earth, the Sellers and the Sellers’ Representative. Upon the terms and subject to the conditions set forth in the Acquisition Agreement, CH LLC will acquire all of the issued and outstanding common stock of Clean Earth for a purchase price of $625 million, subject to adjustments, including the working capital and indebtedness balances of Clean Earth at the time of the closing.

We intend to use the net proceeds from the private debt financing together with borrowings under our Revolving Credit Facility to pay for the Acquisition consideration and related fees, costs and expenses. The consummation of the private financing transaction is conditioned on the contemporaneous closing of the Acquisition.

On May 8, 2019, we also entered into an Asset Purchase Agreement with Acquiror, and, solely to guarantee the performance of the Acquiror’s obligations under the Asset Purchase Agreement, Chart Industries, Inc., a Delaware corporation. Upon the terms and subject to the conditions of the Asset Purchase Agreement, we have agreed to sell, and the Acquiror has agreed to acquire,Air-X-Changers for aggregate cash consideration of $592 million, which is subject to adjustment based on the working capital balance ofAir-X-Changers at the time of the consummation of the Asset Sale, plus the assumption by the Acquiror of the liabilities ofAir-X-Changers specified in the Asset Purchase Agreement.

We intend to use a portion of the proceeds from the Asset Sale to repay up to $320 million of our Term Loan Facility and $150 million of our Revolving Credit Facility. The Acquisition and the private debt financing are not conditioned on the closing of the Asset Sale.

The following unaudited pro forma condensed consolidated financial statements of Harsco, including the explanatory notes (collectively the “pro forma financial statements”), present how the financial statements may have appeared had the private debt financing and our borrowings under our Revolving Credit Facility, as well as the use of proceeds therefrom, including the consummation of each of the Acquisition and the Asset Sale and related transactions and the payment of associated transaction fees and expenses occurred at earlier dates. The unaudited pro forma condensed consolidated statements of operations for each period presented give effect to the Transactions as if they had occurred on January 1, 2018, the first day of the year ended December 31, 2018. The unaudited pro forma condensed consolidated balance sheet as of March 31, 2019 combines the historical consolidated balance sheets giving effect to the Transactions as if they had occurred on March 31, 2019. The summary unaudited pro forma consolidated financial information for the twelve months ended March 31, 2019 has been calculated by adding the unaudited pro forma condensed consolidated financial statements for the three months ended March 31, 2019 to the unaudited pro forma condensed consolidated financial statements for the year ended December 31, 2018, and then subtracting the unaudited pro forma condensed consolidated financial statements for the three months ended March 31, 2018.

The historical consolidated financial information has been adjusted in the pro forma financial statements to give effect to pro forma events that are (i) directly attributable to the Transactions, (ii) factually supportable, and (iii) with respect to the statements of operations, expected to have a continuing impact on Harsco’s consolidated operating results. The unaudited pro forma adjustments are based upon available information and certain assumptions that our management believes are reasonable. The pro forma financial statements should be read in conjunction with the explanatory

1

notes to the pro forma financial statements. In addition, the pro forma financial statements were based on, and should be read in conjunction with, the following historical consolidated financial statements and accompanying notes:

• audited historical consolidated financial statements of Harsco as of, and for the year ended, December 31, 2018, and the related notes;

• audited historical consolidated financial statements of Clean Earth as of, and for the year ended, December 31, 2018, and the related notes;

• unaudited historical condensed consolidated financial statements of Harsco as of, and for the three months ended March 31, 2019 and 2018, and the related notes; and

• unaudited historical condensed consolidated financial statements of Clean Earth as of, and for the three months ended March 31, 2019 and 2018, and the related notes.

The pro forma financial statements and explanatory notes are presented for informational purposes only and do not purport to represent what the results of operations or financial condition would have been had the Transactions occurred on the dates indicated nor do they purport to project the results of operations or financial condition for any future period or as of any future date. We may be required to prepare pro forma financial statements in accordance with Article 11 ofRegulation S-X following the consummation of the private debt financing, the Acquisition and/or Asset Sale. No assurance can be made that differences may not exist.

The Acquisition is considered a business combination and therefore will be accounted for under the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 805—Business Combinations.

We intend to commence the necessary valuation and other studies required to complete the acquisition accounting promptly upon completion of the Acquisition and will finalize the acquisition accounting as soon as practicable within the required measurement period, but in no event later than one year following completion of the Acquisition.

The pro forma financial statements do not reflect the costs of any integration activities or benefits that may result from the realization of future costs savings from operating efficiencies or revenue synergies that may result from the Transactions. Additionally, the pro forma financial statements do not reflect the impact of the Credit Agreement Amendment as the amendment is not directly attributable to the Transactions.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Description of the Transactions

On May 8, 2019, Harsco Corporation (the “Company”, “we”, “our” or “Harsco”), and Calrissian Holdings, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Calrissian”), entered into a Stock Purchase Agreement (the “Acquisition Agreement”) with CEHI Acquisition Corporation, a Delaware corporation (“Clean Earth”), the holders of stock and options in Clean Earth and Compass Group Diversified Holdings LLC (“Compass”), a Delaware limited liability company. Upon the terms and subject to the conditions set forth in the Acquisition Agreement, Calrissian will acquire all issued and outstanding common stock of Clean Earth (the “Acquisition”) for a purchase price of $625.0 million, subject to adjustments, including the working capital and indebtedness balances of Clean Earth at the time of the closing.

We intend to use the net proceeds from the private debt financing, as described herein, together with borrowings under our Revolving Credit Facility, to pay for the Acquisition consideration and related fees, costs and expenses.

Additionally, on May 8, 2019, Harsco entered into the Asset Purchase Agreement with E&C FinFan, Inc., a Delaware corporation (the “Acquiror”), and, solely to guarantee the performance of the Acquiror’s obligations under the Asset Purchase Agreement, Chart Industries, Inc., a Delaware corporation. Upon the terms and subject to the conditions of the Asset Purchase Agreement, Harsco has agreed to sell the Company’sAir-X-Changers business in our Harsco Industrial segment for aggregate cash consideration of $592 million, which is subject to adjustment based on the working capital balance of theAir-X-Changers business at the time of the closing, plus the assumption by the Acquiror of the liabilities of theAir-X-Changers business specified in the Asset Purchase Agreement (the “Asset Sale”).

We intend to use a portion of the proceeds from the Asset Sale to repay up to $320 million of our Term Loan Facility and $150 million of our Revolving Credit Facility.

The Acquisition and Asset Sale are not conditioned on each other and the Acquisition and the private debt financing may be consummated and the Asset Sale may not be consummated or may be closed on different terms.

Note 2—Basis of Presentation

The unaudited pro forma condensed consolidated financial statements of Harsco, including the explanatory notes (collectively the “pro forma financial statements”), present the unaudited pro forma condensed consolidated financial position and results of operations of Harsco based upon the historical financial statements of Harsco and Clean Earth. The pro forma financial statements give effect to the Acquisition, the Asset Sale, and the related financing activities (collectively, the “Transactions”). The pro forma financial statements present how the financial statements may have appeared after giving effect to the Transactions and are intended to reflect the impact of such on Harsco’s consolidated financial statements.

The Acquisition is a business combination and therefore will be accounted for under the acquisition method of accounting under Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 805—Business Combinations. Under the acquisition method of accounting, the total estimated purchase price of an acquisition is allocated to the net tangible and intangible assets based on their estimated fair values. Such valuations are based on available

8

information and certain assumptions that management of Harsco and Clean Earth believe are reasonable. The preliminary allocation of the estimated purchase price to the tangible and intangible assets acquired and liabilities assumed is based on various preliminary estimates. Accordingly, the pro forma adjustments are preliminary and have been made solely for the purpose of providing these pro forma financial statements. Differences between these preliminary estimates and the final acquisition accounting, which will be based on the actual net tangible and identifiable intangible assets that exist as of the closing of the Acquisition, may occur and these differences could be material. The differences, if any, could have a material impact on the pro forma financial statements and Harsco’s future results of operations and financial position.

The pro forma financial statements include certain reclassifications to align the historical presentation of Clean Earth with the presentation utilized by Harsco. SeeNote 3—Reclassificationsherein for additional information on the reclassifications.

The unaudited pro forma condensed consolidated statements of operations (“pro forma statements of operations”) do not reflectthe non-recurring expenses expected to be incurred in connection with the Transactions, including fees to be paid to attorneys, accountants and other professional advisors,the write-off of deferred financing costs, and other transaction-related costs that will not be capitalized. However, the impact of such expenses are reflected in the unaudited pro forma condensed consolidated balance sheet (“pro forma balance sheet”) as a decrease to retained earnings and a corresponding decrease to cash and cash equivalents.

Further, the pro forma financial statements do not reflect the costs of any integration activities or benefits that may result from the realization of future costs savings from operating efficiencies or revenue synergies that may result from the Transactions. As no assurance can be made that the costs will be incurred, or the cost or growth synergies will be achieved, no adjustment has been made. Additionally, the pro forma financial statements do not reflect the impact of the amendment to Harsco’s Senior Secured Credit Facility as the amendment is not directly attributable to the Transactions.

Note 3—Reclassifications

Certain adjustments and reclassifications have been made to the historical presentation of Clean Earth’s financial statements to conform to the presentation used by Harsco within the pro forma financial statements.

Balance Sheet Reclassifications: The following table summarizes the reclassifications made to Clean Earth’s historical balance sheet to conform to Harsco’s financial statement presentation.

Note 4—Estimated Purchase Price and Preliminary Purchase Price Allocation

The pro forma financial statements include a preliminary allocation of the estimated purchase price of Clean Earth to the estimated fair values of assets acquired and liabilities assumed at the acquisition date, assuming the Acquisition occurred on March 31, 2019. The final allocation of the purchase price could differ materially from the preliminary allocation primarily because fluctuations in valuation variables at the time of completion of the Acquisition compared to the amounts assumed for the pro forma adjustments.

13

Estimated purchase price

The following is a summary of the estimated purchase price giving effect to the Acquisition as if it had been consummated on March 31, 2019:

Note 5—Acquisition Related Pro Forma Adjustments

The pro forma financial statements reflect the following adjustments related to the Acquisition:

(a) Cash and cash equivalents

Adjustment to cash and cash equivalents for the following:

(in thousands)	As of March 31, 2019
Cash paid for the Acquisition (1)	$	(606,907	)
Cash paid for transaction costs related to the Acquisition (2)		(9,100	)
Adjustment to cash	$	(616,007	)

(1) Represents the estimated purchase price of the Acquisition as if it had been consummated on March 31, 2019 to account for certain purchase price adjustments.

(2) Represents professional fees paid or expected to be paid in connection with the Acquisition. Any amounts not recorded in the historical financial statements of Harsco through March 31, 2019 were adjusted through the pro forma balance sheet and recorded against retained earnings solely for the purposes of this presentation. As there is no continuing impact of these transaction costs on Harsco’s results, the fees are not included in the pro forma statements of operations.

(b) Property, plant and equipment, net and depreciation expense

Adjustment to the carrying value of Clean Earth’s property, plant and equipment from its recorded net book value to its preliminary estimated fair value. The estimated fair value is expected to be depreciated over the estimated useful lives, on a straight-line basis. The following table is a summary of information related to property, plant and equipment, including information used to calculate the pro forma change in depreciation expense:

		Fair Value as of March 31, 2019		Depreciation Expense
(dollars in thousands)	Estimated Useful Life			Year ended December 31, 2018			Three months ended March 31, 2019			Three months ended March 31, 2018			Twelve months ended March  31, 2019
Land	N/A	$	10,739	$	—		$	—		$	—		$	—
Buildings and improvements	4.5-20 years (1)		19,686		1,104			276			276			1,104
Machinery and equipment	1-9 year(s)		38,863		5,320			1,330			1,330			5,320
Uncompleted construction	N/A		1,757		—			—			—			—
Total fair value of acquired PP&E		$	71,045	$	6,424		$	1,606		$	1,606		$	6,424
Less: Clean Earth’s historical PP&E			61,420		9,832			2,585			2,203			10,214
Pro forma adjustment to PP&E		$	9,625	$	(3,408	)	$	(979	)	$	(597	)	$	(3,790	)

(1) Leasehold improvements are amortized over 4.5 years.

Corresponding adjustments were made to depreciation expense in the pro forma statements of operations as a result of the fair value adjustments to property, plant and equipment as well as changes in useful lives.

15

Pro forma adjustments related to depreciation expense had the following impacts on cost of services sold and selling, general and administrative expenses:

(in thousands)	Year ended December 31, 2018			Three months ended March 31, 2019			Three months ended March  31, 2018			Twelve months ended March  31, 2019
Cost of services sold	$	(2,955	)	$	(808	)	$	(497	)	$	(3,266	)
Selling, general and administrative expenses		(453	)		(171	)		(100	)		(524	)
Total pro forma adjustment	$	(3,408	)	$	(979	)	$	(597	)	$	(3,790	)

The preliminary valuations above, including assignment of useful lives, are based on benchmarking analysis performed with respect to publicly available acquisitions of similar businesses. Final determination of fair value of property, plant and equipment, as well as estimated useful lives, remains subject to change. The finalization may have a material impact on the valuation of property, plant and equipment and the purchase price allocation, which is expected to be finalized subsequent to the Acquisition.

The estimate of fair value and estimated useful lives is preliminary and subject to change once Harsco has sufficient information as to the specific types, nature, age, condition and location of Clean Earth’s property, plant and equipment.

With other assumptions held constant, a 10% change to the fair value of the property, plant and equipment would result in an increase or decrease to depreciation expense of $0.6 million annually and $0.2 million for a three-month period.

(c) Goodwill

Adjustment to goodwill represents the excess of the purchase price over the preliminary fair value of the underlying net tangible and identifiable intangible assets net of liabilities, as shown inNote 4— Estimated Purchase Price and Preliminary Purchase Price Allocation. The adjustment is the difference between the estimated goodwill acquired of $327.0 million and the amount recorded in Clean Earth’s historical financial statements of $140.5 million. The goodwill created in the Acquisition is not deductible for tax purposes.

The adjustment to goodwill is preliminary and subject to change based upon final determination of the fair value of underlying net tangible and identifiable intangible assets acquired net of liabilities assumed and finalization of the purchase price.

16

(d) Intangible assets, net and amortization expense

Adjustment to the carrying value of Clean Earth’s intangible assets from recorded net book value to preliminary estimated fair value. The estimated fair value is expected to be amortized over the estimated useful lives, on a straight-line basis. The following table is a summary of information related to intangible assets, including information used to calculate the pro forma change in amortization expense:

			Fair Value as of March 31, 2019		Amortization Expense
(dollars in thousands)	Estimated Useful Life				Year ended December 31, 2018			Three months ended March 31, 2019			Three months ended March 31, 2018			Twelve months ended March 31, 2019
Tradenames and trademarks		12.5 years	$	20,000	$	1,600		$	400		$	400		$	1,600
Customer relationships		13.5 years		95,000		7,037			1,759			1,759			7,037
Permits and rights		46.5 years		140,000		3,011			753			753			3,011
Total fair value of acquired intangible assets			$	255,000	$	11,648		$	2,912		$	2,912		$	11,648
Less: Clean Earth’s historical intangible assets				131,342		13,850			3,450			3,257			14,043
Pro forma adjustment to intangible assets, net			$	123,658	$	(2,202	)	$	(538	)	$	(345	)	$	(2,395	)

Corresponding adjustments were made to amortization expense in the pro forma statements of operations as a result of the fair value adjustments to intangible assets as well as changes in useful lives.

The preliminary valuations above, including assignment of useful lives, are based on benchmarking analysis performed with respect to publicly available acquisitions of similar businesses. Final determination of fair value of intangible assets, as well as estimated useful lives, remains subject to change. The finalization may have a material impact on the valuation of intangible assets and the purchase price allocation, which is expected to be finalized subsequent to the Acquisition.

With other assumptions held constant, a 10% change to the fair value of the acquired finite live intangible assets would result in an increase or decrease to amortization expense of $1.2 million annually and $0.3 million for a three-month period.

(e) Deferred income tax assets

Adjustment to reclassify Harsco’s historical March 31, 2019 deferred tax asset to net against the pro forma deferred tax liability balance, as a result of acquired deferred tax liabilities from Clean Earth as well as an increase in deferred tax liabilities in certain jurisdictions resulting from purchase accounting (refer toNote 5(i)).

(f) Long-term debt, including current maturities, and interest expense

Adjustments to long-term debt resulted in total decreases of $2.2 million and $213.4 million for current andnon-current portions, respectively. These adjustments related to the extinguishment of Clean Earth’s historical debt obligations which are expected to be completed prior to the closing of the

17

Acquisition. A corresponding adjustment was made to the pro forma statements of operations to eliminate historical interest expense related to the Clean Earth debt that will be extinguished prior to the consummation of the Acquisition.

(g) Accounts payable

Adjustment to remove $0.6 million of transaction costs related to the Acquisition that were historically recorded by Harsco at March 31, 2019 but are being presented in the pro forma balance sheet as being paid in cash on March 31, 2019 (refer toNote 5(a)). A corresponding adjustment was made to the pro forma statement of operations to eliminateone-timenon-recurring transaction costs directly attributable to the Acquisition.

(h) Other current liabilities and transaction costs

Adjustment to increase other current liabilities by $0.8 million includes recording the current portion of a liability related to the securing of air rights payable over a period of 6 years which was entered into by Clean Earth subsequent to March 31, 2019 but prior to execution of the Acquisition Agreement totaling $3.0 million, partially offset by the removal of accrued interest totaling $2.2 million related to the long-term debt discussed inNote 5(f).

(i) Other liabilities

Adjustment to increase other liabilities by $21.3 million includes recording thenon-current portion of a liability related to the securing of air rights payable over a period of 6 years which was entered into by Clean Earth subsequent to March 31, 2019 but prior to execution of the Acquisition Agreement totaling $12.2 million. This adjustment also includes an increase in deferred income tax liabilities resulting from recognizing the deferred tax liability arising from the valuation of Clean Earth’s intangibles on the date the Acquisition Agreement was entered into of $35.9 million, partially offset by the reclassification of Harsco’s historical March 31, 2019 deferred tax assets of $26.9 million to net against the pro forma deferred tax liability balance (refer toNote 5 (e)).

Additionally, other liabilities were impacted by the recognition of an $11.9 million deferred tax asset related to net operating losses for certain transaction costs, which would appear within this caption due to jurisdiction netting of deferred tax positions. This was offset by the adjustment to record the estimated contingent payable to Compass of $11.9 million for those tax benefits, in accordance with the Acquisition Agreement (refer toNote 4).

(j) Stockholders’ equity

Adjustments to eliminate the historical stockholders’ equity of Clean Earth. Adjustment also includes $8.5 million of transaction costs that are presented on the pro forma balance sheet which were not historically recorded by Harsco through March 31, 2019. These costs are being presented in the pro forma balance sheet as being paid in cash on March 31, 2019 (refer toNote 5(a)). No corresponding adjustment was made to the pro forma statement of operations as these areone-timenon-recurring transaction costs which are directly attributable to the Acquisition.

(k) Tax expense

Adjustment to record the income tax impacts of the pro forma adjustments using a blended statutory tax rate of 24.5%. This rate does not reflect Harsco’s effective tax rate, which will include other items and may be significantly different than the rates assumed for purposes of preparing these statements.

18

Note 6—Asset Sale Related Pro Forma Adjustments

The pro forma financial statements reflect the following adjustments related to the Asset Sale:

(a) Historical results

Adjustment to remove the historical results of theAir-X-Changers business from the historical statements of operations of Harsco as if the Asset Sale had occurred on January 1, 2018 and to remove the historical assets and liabilities of theAir-X-Changers business from the historical balance sheet of Harsco as if the Asset Sale had occurred on March 31, 2019.

(b) Cash proceeds

Adjustment to cash and cash equivalents represents the net cash received from the sale of theAir-X-Changers business. Amount was calculated as gross sales proceeds of $592.0 million less the expected income tax obligation and transaction costs of $114.0 million and $8.0 million, respectively. An adjustment was made to eliminate the estimated transaction costs related to the Asset Sale expected to be incurred through the consummation of the Transactions. These costs are recorded against retained earnings solely for the purpose of this presentation.
