The Company also reported adjusted net income for the third quarter of $29.7 million, equal to $0.48 per diluted share, compared to $25.9 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.

Meaningful Year-over-Year Improvement in Operational Performance Despite Ongoing Supply Chain Disruption

"Our businesses were able to deliver meaningful year-over-year improvement in net sales and earnings," commented Jennifer L. Sherman, President and Chief Executive Officer. "Despite the effects of higher material costs and widespread supply chain disruption, which impacted our ability to maximize production efficiencies and deliver products to our customers, we were able to deliver an adjusted EBITDA margin at the high end of our current target range."

In the Environmental Solutions Group, net sales for the third quarter were $249 million, up $18 million, or 8%, compared to the prior-year quarter. In the Safety and Security Systems Group, net sales were $49 million, up 1% from the prior-year quarter.

Consolidated operating income for the third quarter was $34.3 million, up $0.3 million, or 1%, compared to the prior-year quarter. Consolidated operating margin for the third quarter was 11.5%, compared to 12.2% in the prior-year quarter.

Consolidated adjusted earnings before interest, tax, depreciation and amortization ("adjusted EBITDA") for the third quarter was $47.4 million, up $1.5 million, or 3%, compared to the prior-year quarter, and consolidated adjusted EBITDA margin was 15.9%, compared to 16.4% in the prior-year quarter.

In the Environmental Solutions Group, adjusted EBITDA for the third quarter was $42.7 million, compared to $43.9 million in the prior-year quarter, and its adjusted EBITDA margin was 17.1%, compared to 19.0% last year. In the Safety and Security Systems Group, adjusted EBITDA for the third quarter was $8.5 million, up from $8.2 million in the prior-year quarter, and its adjusted EBITDA margin was 17.3%, up from 16.8% last year.

Consolidated orders for the third quarter were $350 million, up $85 million, or 32%, compared to the prior-year quarter. Consolidated backlog at September 30, 2021 was $487 million, a new record for the Company, and up $183 million, or 60%, 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 $16 million was provided by operating activities during the third quarter, bringing the total year-to-date operating cash generation to $55 million. At September 30, 2021, consolidated debt was $252 million, total cash and cash equivalents were $88 million and the Company had $240 million of availability for borrowings under its revolving credit facility.

"Our cash flow generation this year has continued to be strong," said Sherman. "Our current financial position provides us 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 third quarter, reflecting a dividend of $0.09 per share, and the Board of Directors recently declared a similar dividend that will be payable in the fourth quarter. The Company also funded share repurchases of $3.2 million during the third quarter.

Further Extension of Specialty Vehicle Product Offerings Expected with Agreement to Acquire Deist Industries, Inc.

The Company also announced the signing of a definitive agreement to acquire substantially all the assets and operations of each of Deist Industries, Inc., Bucks Fabricating, LLC, Roll-Off Parts, LLC and Switch-N-Go, LLC (collectively "Deist"), all of which are located in Pennsylvania. The transaction includes an initial purchase price of $32.5 million, subject to post-closing adjustments. In addition, there is a contingent earn-out payment of up to $7.5 million, based upon the achievement of certain financial targets over a specified performance period.

Deist designs, manufactures and sells interchangeable truck body systems for class 3-7 vehicles in the work truck industry and a full line of waste hauling products, including front/rear loading containers and specialty roll-off containers. Over the last twelve months, Deist has generated revenues of approximately $41 million, with a double-digit EBITDA margin.

"The acquisition represents another attractive product line extension, and expands our presence in landscaping and waste markets," said Sherman. "With many common partners within our existing distribution channels, the acquisition creates an attractive opportunity to develop and deliver innovative new products and solutions to our customers and optimize the distribution of our products."

"While we did not plan on entering into a transaction this year, when the opportunity to work with Federal Signal arose, we explored it thoroughly," added Matthew Wilson, Chairman and Chief Executive Officer of Deist. "Federal Signal is a known entity to us; we have worked with their businesses in various capacities for the past decade and have developed a mutual respect for one another. As we evaluated a prospective transaction, the synergies between our businesses became increasingly more apparent. Moreover, we share similar cultural traits, highlighted by a strong customer focus, innovative product designs, the development of our employees, and investment in our local communities. Federal Signal has the resources to take the Deist businesses into their next strategic phase of development and enable each division to realize their full potential."

The Company expects to complete the transaction before the end of the year, subject to customary closing conditions, and expects the acquisition to be accretive in the first year.

Outlook

"We continue to see strong momentum in our markets, as evidenced by the 50% improvement in both U.S. municipal and industrial orders so far this year," noted Sherman. "With a record backlog, demand for our products is outpacing the current capacity of our supply chain. During the third quarter, delays in receiving chassis were more prevalent than we had anticipated, causing increased disruption to our production schedules. We expect that the volatile supply chain environment will continue for the rest of the year and, therefore, we are adjusting our full-year adjusted EPS outlook to a new range of $1.68 to $1.78. With good access to labor, and anticipated benefits from recent organic growth investments and acquisitions, we remain encouraged by the long-term opportunities for our businesses, which would be further boosted by infrastructure legislation recently passed by Congress."

CONFERENCE CALL

Federal Signal will host its third quarter conference call on Tuesday, November 9, 2021 at 10:00 a.m. Eastern Time. The call will last approximately one hour. The call may be accessed over the internet through Federal Signal's website at www.federalsignal.com or by dialing phone number 1-855-327-6837 and entering the pin number 10017084.

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 Earnings Per Share ("EPS"):

The Company believes that modifying its 2021 and 2020 net income and diluted EPS provides additional measures which are representative of the Company's underlying performance and improves the comparability of results across reporting periods. During the three and nine months ended September 30, 2021 and 2020 adjustments were made to reported GAAP net income and diluted EPS to exclude the impact of acquisition and integration-related expenses, pension-related charges, restructuring activity, coronavirus-related expenses and purchase accounting effects, where applicable.

Pension-related charges in the three and nine months ended September 30, 2021 and 2020 relate to charges incurred in connection with multi-employer pension plan withdrawals. Such charges are included as a component of Other (income) expense, net on the Condensed Consolidated Statement of Operations.

Coronavirus-related expenses in the three and nine months ended September 30, 2021 and 2020 include direct expenses incurred as a result of the coronavirus pandemic, that are incremental to, and separable from, normal operations. These expenses primarily related to the Company's employee wellness initiatives, including incremental paid time off and reimbursement for certain coronavirus-related expenses.

(c)

Purchase accounting effects relate to adjustments to exclude the step-up in the valuation of acquired JJE equipment that was sold subsequent to the acquisition in the three and nine months ended September 30, 2021 and 2020, as well as to exclude the depreciation of the step-up in the valuation of the rental fleet acquired.

Adjusted income tax expense for the three and nine months ended September 30, 2021 and 2020 was recomputed after excluding the impact of acquisition and integration-related expenses, pension-related charges, restructuring activity, coronavirus-related expenses and purchase accounting effects, where applicable.

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.
