Consolidated net sales for the fourth quarter were $279.4 million, up 13% versus the same quarter a year ago. Fourth quarter income from continuing operations was $32.2 million, equal to $0.53 per diluted share, up 10% compared to $29.3 million, or $0.48 per share, in the prior-year quarter. The Company also reported adjusted income from continuing operations for the fourth quarter of $23.8 million, equal to $0.39 per diluted share, up 65% compared to $14.4 million, or $0.24 per share, in the same quarter a year ago.

Consolidated net sales for the year ended December 31, 2018 were $1,089.5 million, up 21% compared to the prior year. Income from continuing operations for the year was $93.7 million, equal to $1.53 per diluted share, up 55% compared to $60.5 million, or $1.00 per share, in the prior year. Adjusted income from continuing operations for the year was $87.5 million, equal to $1.43 per diluted share, up 71% compared to $51.1 million, or $0.85 per diluted share, in the prior year. 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.

Fourth Quarter Financial Performance Contributes to Record Annual Results

"We had a strong finish to 2018, a year in which our businesses reported record annual revenues and earnings," said Jennifer L. Sherman, President and Chief Executive Officer. "During the fourth quarter, both of our groups achieved double-digit organic sales growth and significant improvements in adjusted EBITDA margins. Benefiting from several large orders, our Safety and Security Group delivered an outstanding quarter, with a 12% increase in the top line, and an EBITDA margin in excess of 20%. With continued momentum on our aftermarket and safe-digging initiatives, and ongoing traction from recent new product introductions, our Environmental Solutions Group reported organic sales growth of 13%, and a 170 basis point year-over-year improvement in adjusted EBITDA margin."

In the Environmental Solutions Group ("ESG"), net sales were up $25.3 million, or 13% primarily due to increases in shipments of vacuum trucks and sewer cleaners, as well as higher aftermarket revenue. Sales in the Safety and Security Systems Group ("SSG") increased by $6.5 million, or 12%, primarily due to higher sales of public safety products and warning systems.

Consolidated fourth quarter operating income was $33.4 million, up $12.3 million, or 58%, compared to the prior-year quarter, driven by improvements of $7.0 million and $2.9 million within ESG and SSG, respectively, in addition to a $2.4 million reduction in corporate expenses.

Consolidated adjusted earnings before interest, tax, depreciation and amortization ("adjusted EBITDA") for the fourth quarter of 2018 was $43.0 million, up $10.9 million, or 34%, compared to the prior-year quarter, and consolidated adjusted EBITDA margin was 15.4% compared to 13.0% last year.

ESG's adjusted EBITDA for the quarter was up $7.5 million, or 27%, to $35.5 million, and its adjusted EBITDA margin was 16.3%, up from 14.6% last year. SSG's adjusted EBITDA for the quarter was $12.7 million, up $2.7 million, or 27%, from last year, and its adjusted EBITDA margin was 20.5%, compared to 18.0% last year.

Order intake in the fourth quarter of 2018 remained strong, with consolidated orders of $297.8 million contributing to a year-end backlog of $338 million, up $80.2 million, or 31%, from a year ago.

Strong Q4 Cash Flow Supports Additional Debt Pay Down and Cash Returns to Shareholders

Net cash of $20.9 million was generated from operations in the fourth quarter of 2018, compared to $21.4 million in the prior-year quarter. For the year ended December 31, 2018, operating cash flow totaled $92.8 million, an increase of $19.3 million, or 26%, compared to the prior year. At December 31, 2018, total debt was $210 million, total cash and cash equivalents were $37 million and the Company had $179 million of availability for borrowings under its credit facility.

"With the 26% year-over-year improvement in operating cash flow, we have paid down approximately $62 million of borrowings in 2018, lowering our debt leverage ratio at the end of the year to 1.3 times adjusted EBITDA," said Sherman. "Our strong financial position allows us to continue to invest in organic growth initiatives, like the recently announced plant expansion at Vactor and ongoing new product development. At the same time, we remain committed to pursuing strategic acquisitions and funding cash returns to shareholders."

The Company funded dividends of $4.9 million during the fourth quarter, bringing the totals for the year to $18.7 million, and the Board of Directors also recently declared a $0.08 per share dividend that will be payable in the first quarter of 2019. In addition, the Company repurchased $1.2 million of stock in the fourth quarter under its existing share repurchase program.

Outlook

"Solid execution drove a record year for Federal Signal, with annual revenues exceeding $1 billion for the first time in over a decade. Both groups reported significant improvement in sales and earnings, delivering adjusted EBITDA margins towards the high end of their target ranges, and our adjusted EPS improved by 68% in comparison to a strong 2017," Sherman continued. "We entered 2019 with a backlog that is 31% higher than a year ago. In addition, conditions in most of our end markets remain healthy and we are gaining traction with our strategic initiatives. Although seasonal effects typically result in our first quarter earnings being lower than subsequent quarters, we are anticipating year-over-year earnings growth in the first quarter. We are expecting another strong year, with revenue growth and adjusted earnings per share^*of between $1.48 and $1.60, the midpoint of which would represent a 9% improvement over a record 2018."

"Safe Harbor" Statement under the Private Securities Litigation Reform Act of 1995

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: economic conditions in various regions; product and price competition; supplier and raw material prices; 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 2018, we made adjustments to exclude the impact of acquisition and integration-related expenses, purchase accounting effects, hearing loss settlement charges and special tax items, where applicable. Should any similar items occur in 2019, 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). In addition, to facilitate comparisons with prior periods, when reporting our interim and annual non-GAAP results in 2019, we will be adjusting our previously issued non-GAAP results for 2018 to exclude the recognition of a deferred gain, which will no longer occur in 2019 following the adoption of the new lease accounting standards. On this basis, Adjusted EPS for 2018 would have been $1.41. At the conclusion of this news release, we have included a reconciliation of GAAP EPS for interim and annual periods in 2018 to both the previously issued and revised adjusted EPS for the interim and annual periods in 2018.

Corporate Expenses

Corporate operating expenses were $5.3 million and $7.7 million for the three months ended December 31, 2018 and 2017, respectively. The decrease was primarily driven by reductions in hearing loss litigation and post-employment expenses, partially offset by increased stock compensation expense.

Corporate operating expenses were $25.6 million and $25.8 million for the years ended December 31, 2018 and 2017, respectively.

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 income and earnings per share from continuing operations ("EPS"):

The Company believes that modifying its 2018 and 2017 income and diluted EPS provides additional measures which are representative of the Company's underlying performance and improve the comparability of results between reporting periods. During the three and twelve months ended December 31, 2018 and 2017, adjustments were made to reported GAAP income and diluted EPS from continuing operations to exclude the impact of restructuring activity, executive severance costs, acquisition and integration-related expenses, purchase accounting effects, pension settlement charges and hearing loss settlement charges, where applicable. In addition, during the three and twelve months ended December 31, 2018 and 2017, adjustments were made to reported GAAP income tax expense to exclude certain special tax items.

(a)	Purchase accounting effects relate to adjustments to exclude the step-up in the valuation of equipment acquired in connection with recent acquisitions that was sold subsequent to the acquisition dates in the three and twelve months ended December 31, 2018 and 2017, as well as to exclude the depreciation of the step-up in the valuation of the rental fleet acquired in the JJE transaction.
(b)	Adjusted income tax expense for the three and twelve months ended December 31, 2018 excludes an $8.6 million net tax benefit associated with tax planning strategies. Adjusted income tax expense for the three and twelve months ended December 31, 2018 also excludes the tax effects of acquisition and integration-related expenses, purchase accounting effects and hearing loss settlement charges, where applicable.
(c)	Adjusted income tax expense for the three and twelve months ended December 31, 2017 excludes a $20.0 million net tax benefit, representing the Company's preliminary estimate of the impact of the 2017 Tax Act, and a $0.8 million benefit from changes in state deferred tax valuation allowance. Adjusted income tax expense for the twelve months ended December 31, 2017 also excludes $0.6 million of tax expense associated with a change in the enacted state tax rate in Illinois. Adjusted income tax expense for the three and twelve months ended December 31, 2017 also excludes the tax effects of restructuring activity, executive severance costs, acquisition and integration-related expenses, purchase accounting effects, hearing loss settlement charges and pension settlement charges, 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 income from continuing operations, interest expense, pension settlement charges, hearing loss settlement charges, acquisition and integration-related expenses, restructuring activity, executive severance costs, purchase accounting effects, other expense/income, income tax expense (benefit), and depreciation and amortization expense. Consolidated adjusted EBITDA margin is a non-GAAP measure that represents the total of income from continuing operations, interest expense, pension settlement charges, hearing loss settlement charges, acquisition and integration-related expenses, restructuring activity, executive severance costs, purchase accounting effects, other expense/income, income tax expense (benefit), 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, 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, 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.

Lease Accounting Change

Effective January 1, 2019, the Company will adopt the new lease accounting standard, which will result in the recognition of right-of-use assets and lease liabilities on the Company's Consolidated Balance Sheet and will result in a change to the Company's recognition of the deferred gain associated with historical sale lease-back transactions. The deferred gain, which initially totaled $29.0 million, has been recognized through the Company's Consolidated Statement of Operations on a straight-line basis over the 15-year life of the respective leases. As a result, approximately $1.9 million of the deferred gain has been recognized each year since 2008, of which approximately $1.1 million and $0.8 million has been recognized within the Environmental Solutions Group and Safety and Security Systems Group, respectively. Effective in 2019, the Company will no longer recognize any portion of the gain through the Consolidated Statement of Operations, and will recognize the remaining deferred gain balance, net of the related deferred tax asset, as a cumulative effect adjustment to opening retained earnings.

To facilitate comparisons with prior periods, when reporting our interim and annual non-GAAP results in 2019, we will be adjusting our previously issued interim and annual non-GAAP results for 2018 to exclude the recognition of this deferred gain. The impact of this adjustment on previously reported adjusted income from continuing operations and adjusted EPS for interim and annual periods in 2018 is reflected in the following tables:
