CAMP HILL, Pa., Aug. 03, 2021 (GLOBE NEWSWIRE) -- Harsco Corporation (NYSE: HSC) today reported second quarter 2021 results. On a U.S. GAAP ("GAAP") basis, second quarter of 2021 diluted earnings per share from continuing operations were $0.18 including certain strategic costs. Adjusted diluted earnings per share from continuing operations in the second quarter of 2021 were $0.28. These figures compare with a second quarter of 2020 GAAP diluted loss per share from continuing operations of $0.14 and adjusted diluted earnings per share from continuing operations of $0.13.

GAAP operating income from continuing operations for the second quarter of 2021 was $36 million. Adjusted EBITDA totaled $78 million in the quarter, compared to the Company's previously provided guidance range of $73 million to $79 million.

"Harsco continued to experience strong growth and operational momentum during the second quarter in each of our businesses," said Chairman and CEO Nick Grasberger. "The underlying business strength has broadened to include certain businesses that had lagged earlier in the economic recovery, and was supported by our ongoing operational improvements and key initiatives. We have also continued to make good progress on our integration with Clean Earth, which remains one of our near term priorities along with the ongoing efforts to strengthening our financial position. I am confident that Harsco is well-positioned to benefit as the global economy strengthens further, and we expect to create additional shareholder value in the future through our ongoing business transformation."

Consolidated Second Quarter Operating Results

Consolidated total revenues from continuing operations were $570 million, an increase of 27 percent compared with the prior-year quarter. Each business segment realized meaningful revenue growth versus the comparable 2020 quarter. Foreign currency translation positively impacted second quarter 2021 revenues by approximately $16 million compared with the prior-year period, translating to an organic growth rate of 24 percent.

GAAP operating income from continuing operations was $36 million for the second quarter of 2021, compared with $2 million in the same quarter of last year. Meanwhile, adjusted EBITDA totaled $78 million in the second quarter of 2021 versus $59 million in the second quarter of 2020. This adjusted EBITDA increase is attributable to improved performance in each of the Company's business segments as a result of strengthening economic conditions, internal improvement actions and growth initiatives.

Second Quarter Business Review

Environmental

($ in millions)	Q2 2021			Q2 2020			Q1 2021
Revenues	$	273		$	204		$	258
Operating income - GAAP	$	30		$	14		$	26
Adjusted EBITDA - excluding unusual items	$	58		$	40		$	54
Adjusted EBITDA margin - excluding unusual items	21.2		%	19.7		%	20.8		%

Environmental revenues totaled $273 million in the second quarter of 2021, an increase of 34 percent compared with the prior-year quarter. This increase is principally attributable to improved demand for environmental services and applied products as well as favorable foreign exchange movements. The segment's GAAP operating income and adjusted EBITDA totaled $30 million and $58 million, respectively, in the second quarter of 2021. These figures compare with GAAP operating income of $14 million and adjusted EBITDA of $40 million in the prior-year period. The year-on-year improvement in adjusted earnings is attributable to increased services and products demand, as noted above.

Clean Earth

($ in millions)	Q2 2021			Q2 2020			Q1 2021
Revenues	$	196		$	162		$	189
Operating income - GAAP	$	7		$	—		$	3
Adjusted EBITDA - excluding unusual items	$	18		$	11		$	15
Adjusted EBITDA margin - excluding unusual items	9.4		%	7.0		%	7.7		%

Note: The 2020 financial information provided above and discussed below for Clean Earth does not include a corporate cost allocation for ESOL.

Clean Earth revenues totaled $196 million in the second quarter of 2021, an increase of 21 percent compared with the prior-year quarter. The revenue increase is attributable to increased environmental services demand within both the hazardous waste and contaminated-dredge materials lines of business. Segment operating income was $7 million and adjusted EBITDA totaled $18 million in the second quarter of 2021. These figures compare with zero operating income and adjusted EBITDA of $11 million, respectively, in the prior-year period. The improvement in adjusted earnings is attributable to the above factors as well as integration improvement benefits. These factors were partially offset by personnel investments to support the Clean Earth platform and certain other expenditures, including IT and rebranding related expenses, which will not occur beyond 2021. Lastly, Clean Earth's adjusted EBITDA margin increased to 9.4 percent in the second quarter of 2021 versus 7.0 percent in the comparable-quarter of 2020.

Rail

($ in millions)	Q2 2021			Q2 2020			Q1 2021
Revenues	$	101		$	82		$	82
Operating income (loss) - GAAP	$	9		$	9		$	5
Adjusted EBITDA - excluding unusual items	$	10		$	10		$	6
Adjusted EBITDA margin - excluding unusual items	10.1		%	12.2		%	7.3		%

Rail revenues increased 24 percent compared with the prior-year quarter to $101 million. This increase principally reflects higher global equipment revenues, including those under various long-term supply contracts. The segment's operating income and adjusted EBITDA totaled $9 million and $10 million, respectively, in the second quarter of 2021, and these figures are similar to results realized in the prior-year quarter. EBITDA performance year-on-year reflects higher equipment contributions, offset by a less favorable sales mix across other business-lines and higher SG&A costs.

Cash Flow

Net cash provided by operating activities totaled $37 million in the second quarter of 2021, compared with net cash provided by operating activities of $33 million in the prior-year period. Free cash flow was $6 million in the second quarter of 2021, compared with $18 million in the prior-year period. The change in free cash flow compared with the prior-year quarter is principally related to higher capital expenditures, some of which were deferred from 2020, as well as the timing of working capital items.

2021 Outlook

The Company's 2021 guidance is unchanged relative to the outlook provided with the Company's first quarter 2021 results. Comments by business segments are as follows:

Environmental. For the year, the primary drivers for an increase in adjusted EBITDA compared with 2020 are expected to be favorable demand for underlying services and products as well as higher commodity prices.

Clean Earth. For the year, adjusted EBITDA is projected to increase due to the full-year impact of ESOL ownership, underlying organic growth for hazardous material services and integration benefits, partially offset by an additional allocation of Corporate costs and investments which include various non-recurring expenditures.

Rail. For the year, the primary drivers for an increase in adjusted EBITDA versus 2020 remain higher anticipated demand for equipment and technology products, as well as higher contract services contributions.

Lastly, adjusted Corporate spending is still expected to range from $36 million to $37 million for the year.

The Company's management believes Adjusted diluted earnings per share from continuing operations, which is a non-GAAP financial measure, is useful to investors because it provides an overall understanding of the Company's historical and future prospects. Exclusion of unusual items permits evaluation and comparison of results for the Company's core business operations, and it is on this basis that management internally assesses the Company's performance. Exclusion of acquisition-related intangible asset amortization expense, the amount of which can vary by the timing, size and nature of the Company's acquisitions, facilitates more consistent internal comparisons of operating results over time between the Company's newly acquired and long-held businesses, and comparisons with both acquisitive and non-acquisitive peer companies. It is important to note that such intangible assets contribute to revenue generation and that intangible asset amortization related to past acquisitions will recur in future periods until such intangible assets have been fully amortized. This measure should be considered in addition to, rather than as a substitute for, other information provided in accordance with GAAP.

Consolidated Adjusted EBITDA is a non-GAAP financial measure and consists of income from continuing operations adjusted to add back income tax expense; equity income of unconsolidated entities, net; net interest expense; defined benefit pension income (expense); unused debt commitment fees, amendment fees and loss on extinguishment of debt; and depreciation and amortization (excluding amortization of deferred financing costs); and excludes unusual items. Segment Adjusted EBITDA consists of operating income from continuing operations adjusted to exclude unusual items and add back depreciation and amortization (excluding amortization of deferred financing costs). The sum of the Segments' Adjusted EBITDA and Corporate Adjusted EBITDA equals Consolidated Adjusted EBITDA. The Company‘s management believes Adjusted EBITDA is meaningful to investors because management reviews Adjusted EBITDA in assessing and evaluating performance. However, this measure should be considered in addition to, rather than as a substitute for, net income from continuing operations, operating income from continuing operations and other information provided in accordance with GAAP. The Company's method of calculating Adjusted EBITDA may differ from methods used by other companies and, as a result, Adjusted EBITDA may not be comparable to other similarly titled measures disclosed by other companies.

(c)		Expenditures directly related to the Company's acquisition and divestiture transactions and costs at Corporate associated with amending the Company's existing Senior Secured Credit Facilities.

The Company's management believes that Free cash flow, which is a non-GAAP financial measure, is meaningful to investors because management reviews cash flows generated from operations less capital expenditures net of asset sales proceeds and transaction-related expenditures and income taxes for planning and performance evaluation purposes. It is important to note that Free cash flow does not represent the total residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements and settlements of foreign currency forward exchange contracts, are not deducted from this measure. This measure should be considered in addition to, rather than as a substitute for, other information provided in accordance with GAAP.
