ELGIN, IL March 1, 2021 — Heritage-Crystal Clean, Inc. (Nasdaq: HCCI), a leading provider of parts cleaning, hazardous and non-hazardous waste services, used oil re-refining, antifreeze recycling and field services primarily focused on small and mid-sized customers, today announced results for the fourth quarter of fiscal 2020 and for the full fiscal year, which ended January 2, 2021.

Fourth Quarter Review

Total Company revenue for the fourth quarter of 2020 declined 4.9% to $132.0 million compared to $138.8 million for the same quarter of 2019. The Company's fourth quarter of fiscal 2020 was comprised of 79 working days compared to 77 working days in the fiscal fourth quarter of 2019. On a sales-per-working day basis, revenue decreased approximately 7.3% compared to the prior year quarter. Lower revenue was primarily the result of the negative impact of the COVID-19 pandemic and related shelter-in-place orders.

Operating margin increased to 19.8% from 18.6% in the fourth quarter of 2020 mainly due to lower field services related disposal costs, workers compensation, and fleet repair costs, partially offset by lower revenues and higher catalyst cost compared to the year-ago quarter. Our SG&A expense as a percentage of revenue increased slightly to 12.3% from 12.1% of revenue in the fourth quarter of 2020 mainly due to lower revenue and higher software licensing fees, partially offset by lower share-based compensation and travel expense.

Net income attributable to common shareholders was $5.3 million, or $0.23 per diluted share, for the fourth quarter of 2020. This compares to a net loss attributable to common shareholders of $2.2 million, or $0.09 per diluted share, in the year earlier quarter which included an $11.0 million pretax charge relating to class action litigation pertaining to fuel surcharges. See our reconciliations of Net income (loss) and Net income (loss) per share below.

Fiscal 2020 Review

In 2020, we generated $406.0 million of revenue compared to prior year revenue of $444.4 million, a decrease of $38.4 million, or 8.7%. The Company's 2020 fiscal year was comprised of 256 working days compared to 253 working days in fiscal 2019. On a sales-per-working day basis, revenue decreased approximately 9.7% in fiscal 2020 compared to the prior year. The decrease in revenue was primarily driven by the negative impacts of the COVID-19 pandemic and related shelter-in-place orders. Since experiencing a 24.3% revenue decline on a year-

over-year basis during the second quarter, amid the depths of the pandemic, our year-over-year revenue deficit shrank to 16.9% in the third quarter and only 4.9% in the fourth quarter.

Operating margin for 2020 was 15.8% compared to 18.1% operating margin in fiscal 2019. The decrease in margin was mainly attributable to lower revenues along with higher insurance expense and field services related disposal costs, partially offset by lower health and welfare costs and lower worker's compensation expense. SG&A expense for fiscal 2020 was 12.7% of revenue, compared to 12.2% of revenue in fiscal 2019.

Net income attributable to common shareholders for fiscal 2020 was $11.9 million, or $0.51 per diluted share, compared to net income of $8.4 million, or $0.36 per diluted share, for fiscal 2019. 2020 full-year net income was favorably impacted by a $6.5 million reversal of an $11.0 million class action lawsuit charge taken in the fourth quarter of fiscal 2019.

Segments

Our Environmental Services segment includes parts cleaning, containerized waste, vacuum services, antifreeze recycling, and field services. The Environmental Services segment reported revenue of $90.9 million, a decrease of $6.0 million, or 6.2%, during the quarter compared to the fourth quarter of fiscal 2019. The decrease in revenue was mainly due to the lingering impacts of COVID-19 related volume declines in our field services, parts cleaning, and containerized waste product and service lines, partially offset by favorable pricing in our parts cleaning business. On a sales-per-working day basis, Environmental Services segment revenue decreased approximately 8.5% compared to the prior year quarter.

Our profit before SG&A expense as a percentage of revenue was 24.6% compared to 25.1% in the year ago quarter. The decline in margin was mainly due to lower revenue and higher depreciation expense for trucks, partially offset by lower field services related disposal costs, worker's compensation expense, and health and welfare costs.

During fiscal 2020, Environmental Services segment revenue decreased $12.0 million, or 4.0%, compared to fiscal 2019, while our 2020 profit before SG&A expense as a percentage of revenue was 22.1% compared to 25.0% in fiscal 2019.

President and CEO Brian Recatto commented, "We are pleased that since the middle of the second quarter we have continually improved our year-over-year performance on both a revenue and operating margin basis despite the continued challenges posed by the impact of the COVID-19 pandemic on our business and our customers."

Our Oil Business segment includes used oil collection activities, sales of recycled fuel oil, and re-refining activities. During the fourth quarter of fiscal 2020, Oil Business revenues decreased 2.0% to $41.1 million compared to the fourth quarter of fiscal 2019. The decrease in revenue was mainly due to lower selling prices of our base oil, partially offset by higher base oil gallons sold during the fourth quarter of 2020 compared to the prior year quarter. On a sales-per-working day basis, our Oil Business segment revenue decreased approximately 4.4% compared to the prior year quarter.

Oil Business segment operating margin improved 5.6 percentage points to 9.1% in the fourth quarter of 2020 compared to 3.5% during the same period of 2019. The increase in margin was mainly due to lower fleet repairs, lower worker's compensation expense, and lower shutdown maintenance, partially offset by higher catalyst costs compared to the year-ago quarter.

Full year 2020 revenue was down $26.5 million compared to fiscal 2019, while operating margin broke even compared to operating margin of 3.3% in fiscal 2019.

Recatto commented, "We are extremely proud of the record high operating margin percentage result achieved during the fourth quarter in our Oil Business Segment. Because of this strong finish to the year, we were able to produce near breakeven operating margin for the full fiscal year 2020 despite the fact that we were forced to idle our re-refinery for most of the month of May due to the negative impacts on the economy from the COVID-19 pandemic."

COVID-19 Update

During the fourth quarter and into the beginning of the first quarter of 2021, we continued executing the Company's pandemic response plan to combat the COVID-19 outbreak-induced downturn in our business and remain focused on ensuring the health and safety of all our employees and their families.

(a)	EBITDA represents net (loss) income before provision for income taxes, interest income, interest expense, depreciation and amortization. We have presented EBITDA because we consider it an important supplemental measure of our performance and believe it is frequently used by analysts, investors, our lenders and other interested parties in the evaluation of companies in our industry. Management uses EBITDA as a measurement tool for evaluating our actual operating performance compared to budget and prior periods. Other companies in our industry may calculate EBITDA differently than we do. EBITDA is not a measure of performance under U.S. GAAP and should not be considered as a substitute for net income (loss) prepared in accordance with U.S. GAAP. EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations are:
	EBITDA does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments;
	EBITDA does not reflect interest expense or the cash requirements necessary to service interest or principal payments on our debt;
	EBITDA does not reflect tax expense or the cash requirements necessary to pay for tax obligations; and
	Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA does not reflect any cash requirements for such replacements.
	We compensate for these limitations by relying primarily on our U.S. GAAP results and using EBITDA only as a supplement.
(b)	Impairment charges mainly associated with the intention to sell the Company's facilities in Wilmington Delaware and Fort Pierce Florida.
(c)	Class action settlement and associated legal fees incurred in fiscal year 2019, and amounts reversed in 2020.
(d)	Non-Cash compensation expenses which are recorded in SG&A.
(e)	Cost and asset write-offs mainly associated with the closure of the Company’s facility located in Wilmington, Delaware.
(f)	Cost associated with severance and other employee separations.
(g)	Revenue deferred during the first quarter of 2019 from the adoption of ASC 842 lease accounting standard, and one-time charges related to implementation of the standard.
(h)	We have presented Adjusted EBITDA because we consider it an important supplemental measure of our performance and believe it may be used by analysts, investors, our lenders, and other interested parties in the evaluation of our performance. Other companies in our industry may calculate Adjusted EBITDA differently than we do. Adjusted EBITDA is not a measure of performance under U.S. GAAP and should not be considered as a substitute for net income (loss) prepared in accordance with U.S. GAAP. Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under U.S. GAAP.

Use of Non-GAAP Financial Measures
Adjusted net earnings (loss) and adjusted net earnings (loss) per share are non-GAAP financial measures. Non-GAAP financial measures should be considered in addition to, but not as substitute for, financial measures prepared in accordance with GAAP. Management believes that adjusted net earnings (loss) and adjusted net earnings (loss) per share provide investors and management useful information about the earnings impact from certain non-routine items for the fourth quarter and full year of 2020 compared to the fourth quarter and full year of 2019.
