Report of Independent Registered Public Accounting Firm

To the Plan Administrator and Plan Participants of the Harsco Retirement Savings and Investment Plan:

Opinion on the Financial Statements

We have audited the accompanying statement of net assets available for benefits of the Harsco Retirement Savings and Investment Plan (the Plan) as of December 31, 2019, and the related statement of changes in net assets available for benefits for the year then ended, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2019 and the changes in net assets available for benefits for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental Schedule of Assets (Held at End of Year) as of December 31, 2019 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Harsco Corporation Retirement Savings and Investment Plan (the “Plan”) as of December 31, 2018 and the related notes (collectively, the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2018 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risk of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by the Plan’s management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

HARSCO RETIREMENT SAVINGS AND INVESTMENT PLAN

NOTES TO FINANCIAL STATEMENTS

December 31, 2019 and 2018


1.	Plan Description

The following description of the Harsco Retirement Savings and Investment Plan (the “Plan”) provides only an abbreviated summary of the general provisions of the Plan. Participants should refer to the Summary Plan Description and the Plan document for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution plan providing retirement benefits to eligible employees. The Plan is designed to comply with the requirements of the Employee Retirement Income Security Act of 1974 ("ERISA") and with the requirements for qualification under Sections 401(a) and 401(k) of the Internal Revenue Code ("IRC").

All U.S. salaried employees and non-union hourly employees (including officers), who are employed by Harsco Corporation (“the Company”) or any eligible subsidiary of either the Company or a subsidiary which adopts this Plan with the approval of the Company and who are not participants in the Harsco Corporation Savings Plan, are deemed "Eligible Employees.”

Throughout the year, employees may be transferred to various positions within the Company, which may result in a transfer between various retirement plans sponsored by the Company. Transfers between various Company retirement plans may also occur as Plan amendments are adopted to permit additional or restrict existing groups of Company employees participating in the Plan. These are shown as “Net transfer in due to employee classification change” on the Statement of Changes in Net Assets Available for Benefits.

Contributions

New eligible employees are automatically enrolled in the Plan at a pre-tax savings rate of 3% via payroll deductions with contributions being directed to a designated target date fund based on the participant's current age and a retirement age of 65. Employees have the option to opt out of this Plan or to contribute an amount different than the automatic contribution amount, and/or to invest in funds other than the Plan's default fund that are available within the Plan investment options.

Participants may contribute up to 75% of their annual compensation received as an employee, as defined in the Plan and subject to Internal Revenue Code limitations. Participant contributions may be made on a pretax basis, or participants may elect to make contributions on an after-tax basis, subject to limitations outlined in the Plan. Participants who are at least age 50 may make an additional "catch-up" contribution subject to IRC limitations. Participants may also contribute funds from another qualified retirement plan ("rollover" contributions), subject to certain requirements. The Company makes matching contributions equal to 100% of the first 3% of such participant's contributions and 50% of the next 2% of each Participant's contributions.

The Company may make a discretionary contribution to the Plan in an amount determined by the Company's Board of Directors. Employer discretionary contributions are allocated to the accounts of eligible participants in the proportion that each eligible participant's compensation bears to the aggregate compensation of all eligible participants who are entitled to an allocation of the Company discretionary contribution for that Plan year. The Company made no discretionary contributions for the Plan year ended December 31, 2019.

Participant Accounts

Each participant's account is credited with the participant's contributions and employer matching contributions, as well as allocations of any discretionary contributions and Plan earnings. Participant accounts are charged with an allocation of administrative expenses that are paid by the Plan. Allocations are

based on participant earnings, account balances, or specific transactions, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

Vesting

Participants are immediately vested in their contributions plus actual earnings thereon and matched pre-tax contributions and matched after-tax contributions to the Plan. Participants are 100% vested in the Company's discretionary contributions after three years of credited service. Participants are also 100% vested upon death, disability or the attainment of normal retirement age. For amounts transferred to this Plan from the Harsco Corporation Savings Plan, a participant is vested in the Company's discretionary contributions after three years of credited service.

Notes Receivable from Participants

Participants may borrow from their fund accounts a minimum of $500 to a maximum of 50% of their vested account balance, not to exceed $50,000. A loan is collateralized by the balance in the participant's account and bears interest at a rate commensurate with local prevailing rates as determined periodically by the Plan administrator. The participant may choose the loan repayment period, not to exceed five years. However, the term may be for any period not to exceed 15 years if the purpose of the loan is to acquire the participant's principal residence. No more than one loan may be outstanding at anytime. Interest rates on outstanding loans, based on the prime rate plus one percent, ranged from 4.25% to 6.50% at December 31, 2019, with maturity dates ranging from 2020 to 2032. Principal and interest is paid ratably through payroll deductions. Delinquent participant loans are reclassified as distributions based on the terms of the plan document. Notes receivable from participants are carried at unpaid principal plus accrued, but unpaid interest.

Payment of Benefits

On termination of service, a participant or beneficiary may elect one of three options: to receive a lump-sum amount equal to the value of the participant's vested interest in his or her account; a portion paid in a lump-sum, and the remainder paid later; or annual installments over not more than 15 years.

A participant may also request a withdrawal upon attainment of age 59 1/2 or upon demonstration by the participant to the plan administrator that the participant is suffering from "hardship". Hardship is defined in applicable regulations promulgated or to be promulgated pursuant to Section 401 (k) of the Internal Revenue Code or standards established by the Secretary of the Treasury or his delegate. A participant may also request a withdrawal from after-tax and rollover funds at any time.


2.	Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan are prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP").

Administration

The Plan participants pay investment management, recordkeeping and audit fees related to maintaining the Plan as a whole. Loan setup fees and withdrawal fees are paid by the participant. Purchases and sales of the Company's Common Stock are assessed a commission per share, which is paid by the participant. This fee is $0.02 per share. Investment related expenses are included in Net appreciation of the fair value of investments on the Statement of Changes in Net Assets Available for Benefits.

Investment Valuation and Income Recognition

Investments are reported at fair value, which is 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 (an exit price). The Plan's Investment Committee determines the Plan's investment options utilizing information provided by the investment advisers and custodians. See Note 4, Fair Value Measurements.

Purchases and sales of investments are recorded on a trade-date basis. Dividend income is recorded on the ex-dividend date. Net appreciation of the fair value of investments includes the Plan's gains and losses on investments bought and sold as well as unrealized gains and losses on investments held at year end.

Payment of Benefits

Benefit payments to participants are recorded when paid.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates.

Forfeitures

Forfeitures, which are a result of participant withdrawals prior to their full vesting in the Plan, are used to reduce the amount of future employer contributions, pay plan expenses or restore accounts, as directed by the Plan Administrator. In 2019, $4 thousand of forfeitures were used to offset employer contributions. Unallocated forfeitures at December 31, 2019 and 2018, were $0 thousand and $4 thousand, respectively.

Subsequent Events

The Company and Plan has performed an evaluation of events subsequent to December 31, 2019 and through the date of financial statement issuance which would require adjustment to or additional disclosure in the financial statements. No events were identified.

The 2019 novel coronavirus (or "COVID-19") has adversely affected, and may continue to adversely affect, the values of the investments held by the Plan. The extent of the adverse impact of the COVID-19 outbreak on the Plan's investments cannot be predicted at this time.

The Coronavirus Aid Relief, and Economic Security Act (CARES Act) was passed by the U.S. Senate on March 26, 2020. Section 2202 of the CARES Act permits eligible Plan participants to request penalty-free distributions of up to $100,000 for qualifying coronavirus-related reasons. These reasons include adverse financial consequences due to being quarantined, furloughed, laid off, having work hours reduced or being unable to work due to a lack of childcare due to COVID-19. Plan Management is in the process of reviewing the CARES Act and any resulting changes to the Plan.

Recent Accounting Pronouncements

On January 1, 2019, the Plan adopted ASU 2017-06, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): Employee Benefit Plan Master Trust Reporting. This update requires disclosure of the dollar amount of the Plan’s interest in each type of investment held by a Master Trust, as well as the Master Trust’s other assets and liabilities on a gross basis and the dollar amount of the Plan’s interest in each balance. The adoption of these changes required additional disclosures by the Plan. See Note 3, Master Trust, for additional information.


3.	Master Trust

A portion of the Plan's investments are in the Harsco Savings Plan Stock Fund ("Master Trust"), which was established for the investment of assets of the Plan and another retirement plan sponsored by the Company. Each participating retirement plan has an undivided interest in the Master Trust. The assets of the Master Trust are held by Wells Fargo Bank, N.A. The value of the Plan's interest in the Master Trust is based on the beginning of year value of the Plan's interest in the trust plus actual contributions and allocated investment

income less actual distributions and allocated administrative expenses. At both December 31, 2019 and 2018, the Plan's interest in the net assets of the Master Trust was 62.68% and 67.29%, respectively. Investment income and administrative expenses relating to the Master Trust are allocated to the individual plans based upon the amount of the time the plan's assets were invested in the Master Trust.

The following table presents the net assets in the Master Trust.



	December 31, 2019				December 31, 2018
(In thousands)	Plan		Master Trust		Plan		Master Trust
Harsco stock	$	13,413	$	21,399	$	15,750	$	23,406
Money market mutual fund	242		386		294		436
Total	$	13,655	$	21,785	$	16,044	$	23,842

The changes in net assets of the Master Trust for the year ended December 31, 2019 consists of the following:



(In thousands)	Plan			Master Trust
Net appreciation in fair value of investments	$	2,199		$	3,412
Interest and dividend income	5			8
Net investment income	2,204			3,420
Net transfers	(4,593		)	(5,477		)
Net decrease in assets	(2,389		)	(2,057		)
Net assets:
Beginning of year	16,044			23,842
End of year	$	13,655		$	21,785

At December 31, 2019 and 2018, all assets of the Master Trust (Harsco stock and Mutual funds) are classified within Level 1 of the fair value hierarchy discussed in Note 4, due to the fact that the inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.


4.	Fair Value Measurements

The fair value framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:


Level 1	Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2 Inputs to the valuation methodology include:

•Quoted prices for similar assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in inactive markets;

•Inputs other than quoted prices that are observable for the asset or liability; and


•	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.


Level 3	Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset's or liability's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Plan primarily applies the market approach for fair value measurements and endeavors to utilize the best available information. Accordingly, the Plan utilizes valuation techniques that maximize the use of observable inputs, such as quoted prices in active markets, and minimize the use of unobservable inputs. The Plan is able to classify fair value balances based on the observability of those inputs. Common stock is valued at the closing price reported on the active market on which the individual security is traded. Investments in mutual funds are primarily valued at net asset value in an exchange and active market, which represents the net asset values of shares held by the Plan at year-end.

The Plan recognizes the methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While the Plan believes its valuation methods are appropriate and consistent with other market participants expectations for the Plan's investments, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement. There have been no significant changes in the valuation methodologies or transfers between levels during the years ended December 31, 2019 and 2018.

At December 31, 2019 and 2018, the Plan's investment that are not included in the Master Trust are Mutual funds and are classified within Level 1 of the fair value hierarchy, due to the fact that the inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.


5.	Related-Party and Party in Interest Transactions

The majority of the Plan's investments are shares of mutual funds managed by Wells Fargo Bank, N.A., trustee, custodian and recordkeeper. These transactions qualify as party in interest transactions. Fees paid by the Plan for the investment management services amounted to $150 thousand for the year ended December 31, 2019.

Transactions in the Company's Common Stock also qualify as party in interest transactions. For the year ended December 31, 2019, the Plan purchased, on behalf of participants, $522 thousand and sold $4,820 thousand of the Company's common stock.

Additionally, notes receivable from participants qualify as party in interest transactions. For the year ended December 31, 2019, the Plan received $114 thousand in interest income on notes receivable from participants.


6.	Plan Termination

Although the Company has not expressed any intent to discontinue the Plan, it reserves the right to terminate the Plan at any time or discontinue contributions and loans thereunder, subject to the provisions of ERISA. In the event of Plan termination, the accounts of each affected employee would be fully vested. Complete distributions or withdrawals would be distributed to Plan participants and beneficiaries in proportion to their respective account balances.

A partial plan termination was deemed to have occurred with respect to participants terminated in connection with the sale of the Company's Harsco Industrial Air-X-Changers business to Chart Industries, Inc, the sale of its Harsco Industrial Patterson-Kelly business to SPX Corporation and other location closures. In accordance with IRC provisions, all participants involved in the termination were fully vested in their accounts.


7.	Tax Status

The IRS has determined and informed the Company by a letter dated July 23, 2018, that the Plan and related trust are designed in accordance with applicable sections of the IRC. Although the Plan has been amended since receiving the opinion letter, the plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC and therefore believes that the Plan is qualified, and the related trust is tax-exempt. U.S. GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions by the Plan, and has concluded that as of December 31, 2019, there are no uncertain positions taken or expected to be taken that would require recognition of a liability or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.


8.	Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits.


9.	Plan Transfers

In July 2019, the Company sold its Air-X-Changers business to Chart Industries,Inc. The account balances related to this business, including participant loans totaling $17,401 thousand were transferred to Chart Industries, Inc. 401(k) Investment and Savings Plan as part of this divestiture.

In May 2018, the Company acquired Altek Europe Holdings Limited and its affiliated entities and in 2019, the account balances related to the Altek 401(k) Profit sharing Plan were transferred into the Plan.
