Strong Fourth Quarter Performance Wraps up Record Year; Customer Demand at Unprecedented Levels; Increasing EBITDA Margin Target for the Safety and Security Systems Group

"Our record-setting fourth quarter performance represented a strong finish to a year in which we delivered the highest net sales and adjusted EPS in our history," commented Jennifer L. Sherman, President and Chief Executive Officer. "Within our Environmental Solutions Group, increased sales volumes, contributions from recent acquisitions, and strong price realization contributed to a 33% year-over-year net sales increase and a 300 basis point improvement in EBITDA margin. Our Safety and Security Systems Group also delivered impressive results, with double-digit top line growth and an EBITDA margin of approximately 20%, despite a week-long plant shutdown at our University Park facility in December due to a power outage. With its consistently strong performance over the last several quarters, we are increasing the EBITDA margin target for our Safety and Security Systems Group to a new range of 17% to 21%, from the previous range of 15% to 18%. Demand for our products remains high, with our order intake this quarter representing the second highest quarterly orders in our history, contributing to a record backlog of $879 million at the end of 2022."

In the Environmental Solutions Group, net sales for the fourth quarter were $325 million, up $80 million, or 33%, compared to the prior-year quarter, while in the Safety and Security Systems Group, net sales for the fourth quarter were $66 million, up $10 million, or 18%, compared to the prior-year quarter.

Consolidated operating income for the fourth quarter was $46.6 million, up $16.5 million, or 55%, compared to the prior-year quarter. Consolidated operating margin for the fourth quarter was 11.9%, compared to 10.0% last year.

Consolidated adjusted earnings before interest, tax, depreciation and amortization ("adjusted EBITDA") for the fourth quarter was $61.1 million, up $21.1 million, or 53%, compared to last year, and consolidated adjusted EBITDA margin in the current-year quarter was 15.6%, compared to 13.3% last year.

Adjusted EBITDA in the Environmental Solutions Group for the fourth quarter was $57.6 million, up $21.4 million, or 59%, compared to last year, and its adjusted EBITDA margin in the current-year quarter was 17.7%, up from 14.7% last year. Within the Safety and Security Systems Group, adjusted EBITDA for the fourth quarter was $13.2 million, up $2.2 million, or 20%, compared to the prior-year quarter, and its adjusted EBITDA margin in the current-year quarter was 19.9%, up from 19.7% last year.

Orders for the fourth quarter were $444 million, the second highest quarterly orders in the Company's history. With the strong momentum in customer demand, consolidated backlog at December 31, 2022 was at an all-time high level of $879 million, an improvement of $250 million, or 40%, from last year.

New Credit Facility and Healthy Cash Flow Supports M&A, Organic Growth Investment and Cash Returns to Shareholders

Net cash of $39 million was generated from operations in the fourth quarter, bringing the total year-to-date operating cash generation to $72 million.

During the fourth quarter, the Company completed the acquisition of TowHaul Corporation and also closed the acquisition of Blasters, Inc. in January 2023. Last week, the Company also announced the signing of a definitive agreement to acquire substantially all the assets and operations of Trackless Vehicles Limited, a leading Canadian manufacturer of multi-purpose, off-road municipal tractors and attachments.

At December 31, 2022, total debt was $363 million, total cash and cash equivalents were $48 million and the Company had $428 million of availability for borrowings under its new, five-year credit facility that was executed during the fourth quarter.

"With our financial position strengthened by the increased borrowing capacity under our new credit facility and our healthy cash generation, we have significant financial flexibility to invest in organic growth initiatives and fund cash returns to stockholders. We also intend to pursue additional strategic acquisitions, like Trackless, which represents the fifth acquisition announced in the last 16 months, all of which have been internally-sourced." said Sherman.

During the fourth quarter, the Company funded dividends of $5.4 million, and recently declared a similar $0.09 per share dividend that will be payable in the first quarter of 2023.

Outlook

"Conditions in our end markets remain strong, and with the ongoing execution against our strategic initiatives and opportunities to drive improved efficiencies, we are confident that we will have another record year in 2023," noted Sherman. "We have started to see benefits from federal stimulus funding in our recent order trends and improvement in supply chain. Although seasonal effects typically result in our first quarter earnings being lower than subsequent quarters, we are anticipating full-year net sales of between $1.58 billion and $1.72 billion, double-digit improvement in pre-tax earnings and EBITDA margin performance towards the upper end of our target range. For the full-year, we currently expect to report adjusted EPS* of between $2.15 and $2.40 per share, despite an aggregate year-over-year EPS headwind of approximately $0.23 per share resulting from the normalization of our tax rate and higher interest expense. With an active M&A pipeline, ongoing investment in new product development, recently-completed capacity expansions, good access to skilled labor, and anticipated multi-year tailwinds from infrastructure legislation and economic stimulus, our businesses are well positioned for long-term, sustainable growth."

This release contains unaudited financial information and various forward-looking statements as of the date hereof and we undertake no obligation to update these forward-looking statements regardless of new developments or otherwise. Statements in this release that are not historical are forward-looking statements. Such statements are subject to various risks and uncertainties that could cause actual results to vary materially from those stated. Such risks and uncertainties include but are not limited to: direct and indirect impacts of the coronavirus pandemic and the associated government response, risks and adverse economic effects associated with emerging geopolitical conflicts, product and price competition, supply chain disruptions, work stoppages, availability and pricing of raw materials, cybersecurity risks, risks associated with acquisitions such as integration of operations and achieving anticipated revenue and cost benefits, foreign currency exchange rate changes, interest rate changes, increased legal expenses and litigation results, legal and regulatory developments and other risks and uncertainties described in filings with the Securities and Exchange Commission.

Adjusted earnings per share ("EPS") is a non-GAAP measure, which includes certain adjustments to reported GAAP net income and diluted EPS. In 2022, we made adjustments to exclude the impact of acquisition and integration-related expenses (benefits) and debt settlement charges, where applicable. Should any similar items occur in 2023, we would expect to exclude them from the determination of adjusted EPS. However, because of the underlying uncertainty in quantifying amounts which may not yet be known, a reconciliation of our Adjusted EPS outlook to the most applicable GAAP measure is excluded based on the unreasonable efforts exception in Item 10(e)(1)(i)(B).

SEC REGULATION G NON-GAAP RECONCILIATION

The financial measures presented below are unaudited and are not in accordance with U.S. generally accepted accounting principles ("GAAP"). The non-GAAP financial information presented herein should be considered supplemental to, and not a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company has provided this supplemental information to investors, analysts, and other interested parties to enable them to perform additional analyses of operating results, to illustrate the results of operations giving effect to the non-GAAP adjustments shown in the reconciliations below, and to provide an additional measure of performance which management considers in operating the business.

Adjusted net income and adjusted earnings per share ("Adjusted EPS"):

The Company believes that modifying its 2022 and 2021 net income and diluted earnings per share ("EPS") provides additional measures which are representative of the Company's underlying performance and improve the comparability of results between reporting periods. Adjusted net income and Adjusted EPS are both non-GAAP measures. During the three and twelve months ended December 31, 2022 and 2021, adjustments were made to reported GAAP net income and diluted EPS to exclude the impact of acquisition and integration-related expenses (benefits), pension-related charges, coronavirus-related expenses, debt settlement charges, and purchase accounting effects, where applicable.

(b)	Coronavirus-related expenses in the twelve months ended December 31, 2021 relate to direct expenses incurred in connection with the Company's response to the coronavirus pandemic, that are incremental to, and separable from, normal operations. Such expenses primarily relate to incremental paid time off provided to employees and costs incurred to implement enhanced workplace safety protocols.
(c)	Purchase accounting effects in the three and twelve months ended December 31, 2021 relate to adjustments to exclude the step-up in the valuation of equipment acquired in recent business combinations that was sold during the periods presented.
(d)	Adjusted income tax expense for the three and twelve months ended December 31, 2022 and 2021 was recomputed after excluding the impact of acquisition and integration-related expenses (benefits), pension-related charges, coronavirus-related expenses, debt settlement charges, and purchase accounting effects, where applicable.

Adjusted EBITDA:

The Company uses adjusted EBITDA and the ratio of adjusted EBITDA to net sales ("adjusted EBITDA margin"), at both the consolidated and segment level, as additional measures which are representative of its underlying performance and to improve the comparability of results across reporting periods. We believe that investors use versions of these metrics in a similar manner. For these reasons, the Company believes that adjusted EBITDA and adjusted EBITDA margin, at both the consolidated and segment level, are meaningful metrics to investors in evaluating the Company's underlying financial performance.

Consolidated adjusted EBITDA is a non-GAAP measure that represents the total of net income, interest expense, pension settlement charges, acquisition and integration-related expenses (benefits), coronavirus-related expenses, debt settlement charges, purchase accounting effects, other expense/income, income tax benefit/expense, and depreciation and amortization expense, as applicable. Consolidated adjusted EBITDA margin is a non-GAAP measure that represents the total of net income, interest expense, pension settlement charges, acquisition and integration-related expenses (benefits), coronavirus-related expenses, debt settlement charges, purchase accounting effects, other expense/income, income tax benefit/expense, and depreciation and amortization expense, as applicable, divided by net sales for the applicable period(s).

Segment adjusted EBITDA is a non-GAAP measure that represents the total of segment operating income, acquisition and integration-related expenses, coronavirus-related expenses, purchase accounting effects, and depreciation and amortization expense, as applicable. Segment adjusted EBITDA margin is a non-GAAP measure that represents the total of segment operating income, acquisition and integration-related expenses, coronavirus-related expenses, purchase accounting effects, and depreciation and amortization expense, as applicable, divided by net sales for the applicable period(s). Segment operating income includes all revenues, costs and expenses directly related to the segment involved. In determining segment income, neither corporate nor interest expenses are included. Segment depreciation and amortization expense relates to those assets, both tangible and intangible, that are utilized by the respective segment.

Other companies may use different methods to calculate adjusted EBITDA and adjusted EBITDA margin.
