Consolidated net sales for the second quarter were $335 million, up $65 million, or 24%, compared to the prior-year quarter. Net income for the second quarter was $29.7 million, equal to $0.48 per diluted share, compared to $21.4 million, equal to $0.35 per diluted share, in the prior-year quarter.
The Company also reported adjusted net income for the second quarter of $30.6 million, equal to $0.50 per diluted share, compared to $25.8 million, or $0.42 per diluted share, in the prior-year quarter. The Company is reporting adjusted results to facilitate comparisons of underlying performance on a year-over-year basis. A reconciliation of these and other non-GAAP measures is provided at the conclusion of this news release.
Strong Operational Performance Despite Ongoing Supply Chain Disruption
“We delivered another strong quarter, with operating results exceeding our expectations, despite ongoing supply chain disruption associated with the global shortage in semiconductors,” commented Jennifer L. Sherman, President and Chief Executive Officer. “Thanks to the proactive actions taken by our teams, we were able to respond to customer demand by delivering more units than we had anticipated. Aftermarket demand during the quarter was also higher than expected, which helped to partially offset the effects of higher material costs.”
In the Environmental Solutions Group, net sales for the second quarter were $281 million, up $67 million, or 31%, compared to the prior-year quarter. In the Safety and Security Systems Group, net sales were $53 million, compared to $56 million in the prior-year quarter.
Consolidated operating income for the second quarter was $38.5 million, up $7.2 million, or 23%, compared to the prior-year quarter. Consolidated operating margin for the second quarter was 11.5%, compared to 11.6% in the prior-year quarter.
Consolidated adjusted earnings before interest, tax, depreciation and amortization (“adjusted EBITDA”) for the second quarter was $51.9 million, up $6.5 million, or 14%, compared to the prior-year quarter, and consolidated adjusted EBITDA margin was 15.5%, compared to 16.8% last year.
In the Environmental Solutions Group, adjusted EBITDA for the second quarter was $50.6 million, up $9.7 million, or 24%, compared to the prior-year quarter, and its adjusted EBITDA margin was 18.0%, compared to 19.1% last year. In the Safety and Security Systems Group, adjusted EBITDA for the second quarter was $8.7 million, compared to $11.7 million in the prior-year quarter, and its adjusted EBITDA margin was 16.3%, compared to 20.9% last year.

Consolidated orders for the second quarter were $361 million, up $159 million, or 79%, compared to the prior-year quarter. Consolidated backlog at June 30, 2021 was $437 million, a new record for the Company, and up $133 million, or 44%, from the end of last year.
Financial Position Remains Strong, Providing Flexibility to Invest in Organic Growth, Fund M&A and Return Cash to Stockholders
Net cash of $13 million was provided by operating activities during the second quarter, bringing the total year-to-date operating cash generation to $39 million.
At June 30, 2021, consolidated debt was $224 million, total cash and cash equivalents were $55 million and the Company had $268 million of availability for borrowings under its revolving credit facility.
“Our cash flow so far this year has been strong. During the quarter, we elected to accelerate the timing of certain tax payments in connection with ongoing tax strategies,” said Sherman. “With our current financial position, we have significant flexibility to pursue strategic acquisitions, invest in organic growth initiatives, and return cash to stockholders through dividends and opportunistic share repurchases.”
The Company funded dividends of $5.5 million during the second quarter, reflecting an increased dividend of $0.09 per share, and the Board of Directors recently declared a similar dividend that will be payable in the third quarter.
Outlook
“Demand for our products continues to be high, with our second quarter order intake up 79% compared to the prior year, resulting in a backlog entering the second half of the year which is at a record level,” noted Sherman. “The strength of our second quarter earnings, our record backlog and improving aftermarket demand in North America gives us increased confidence in the year. Assuming no significant delays in our receipt of chassis from our suppliers, we are increasing our adjusted EPS* outlook for the year to a new range of $1.78 to $1.90, from the prior range of $1.73 to $1.85. We are also encouraged by the long-term opportunities that infrastructure legislation would create for almost all of our businesses. With our recent capacity expansions, we would be well positioned to meet the associated increase in demand for our products.”

* Adjusted earnings per share (“EPS”) is a non-GAAP measure, which includes certain adjustments to reported GAAP net income and diluted EPS. When reporting adjusted EPS in 2021, we have made, and would expect to continue to make, certain adjustments to exclude the impact of acquisition and integration-related expenses, pension-related charges, coronavirus-related expenses and purchase accounting effects, where applicable. In prior years, we have also made adjustments to GAAP net income and diluted EPS for restructuring activity, hearing loss settlement charges and special tax items. Should any similar items occur in 2021, we would also 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).

Adjusted EBITDA and Adjusted EBITDA Margin:
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, acquisition and integration-related expenses, restructuring activity, coronavirus-related expenses, purchase accounting effects, other income/expense, income tax expense, and depreciation and amortization expense. Consolidated adjusted EBITDA margin is a non-GAAP measure that represents the total of net income, interest expense, acquisition and integration-related expenses, restructuring activity, coronavirus-related expenses, purchase accounting effects, other income/expense, income tax expense, and depreciation and amortization expense 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, restructuring activity, 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, restructuring activity, 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.
