FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q (“Form 10-Q”) is being filed by Federal Signal Corporation and its subsidiaries (referred to collectively as the “Company,” “we,” “our” or “us” herein, unless the context otherwise indicates) with the United States (“U.S.”) Securities and Exchange Commission (the “SEC”), and includes comments made by management that may contain words such as “may,” “will,” “believe,” “expect,” “anticipate,” “intend,” “plan,” “project,” “estimate” and “objective” or similar terminology, or the negative thereof, concerning the Company’s future financial performance, business strategy, plans, goals and objectives. These expressions are intended to identify forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Private Securities Litigation Reform Act of 1995. Forward-looking statements include information concerning the Company’s possible or assumed future performance or results of operations and are not guarantees. While these statements are based on assumptions and judgments that management has made in light of industry experience as well as perceptions of historical trends, current conditions, expected future developments and other factors believed to be appropriate under the circumstances, they are subject to risks, uncertainties and other factors that may cause the Company’s actual results, performance or achievements to be materially different.
These risks and uncertainties, some of which are beyond the Company’s control, include the risk factors described under Part I, Item 1A, Risk Factors, of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on March 1, 2023. These factors may not constitute all factors that could cause actual results to differ materially from those discussed in any forward-looking statement. The Company operates in a continually changing business environment and new factors emerge from time to time, including, for example, the ongoing coronavirus pandemic and the government response to the pandemic. The Company cannot predict such factors, nor can it assess the impact, if any, of such factors on its results of operations, financial condition or cash flow. Accordingly, forward-looking statements should not be relied upon as a predictor of actual results. The Company disclaims any responsibility to update any forward-looking statement provided in this Form 10-Q.
ADDITIONAL INFORMATION
The Company is subject to the reporting and information requirements of the Exchange Act and, as a result, is obligated to file Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other reports and information with the SEC, as well as amendments to those reports. The Company makes these filings available free of charge through our website at www.federalsignal.com as soon as reasonably practicable after such materials are filed with, or furnished to, the SEC. Information on our website does not constitute part of this Form 10-Q. In addition, the SEC maintains a website at www.sec.gov that contains reports, proxy and information statements, and other information regarding issuers that file electronically.

The accompanying unaudited condensed consolidated financial statements represent the consolidation of Federal Signal Corporation and its subsidiaries included herein and have been prepared by the Company pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures presented herein are adequate to ensure the information presented is not misleading. Except as otherwise noted, these condensed consolidated financial statements have been prepared in accordance with the Company’s accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, and should be read in conjunction with those consolidated financial statements and the notes thereto.
These condensed consolidated financial statements include all normal and recurring adjustments that we considered necessary to present a fair statement of our results of operations, financial condition and cash flow. Intercompany balances and transactions have been eliminated in consolidation.
The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year, which may differ materially due to, among other things, the risk factors described under Part I, Item 1A, Risk Factors, of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on March 1, 2023. While we label our quarterly information using a calendar convention whereby our first, second and third quarters are labeled as ending on March 31, June 30 and September 30, respectively, it is our longstanding practice to establish interim quarterly closing dates based on a 13-week period ending on a Saturday, with our fiscal year ending on December 31. The effects of this practice are not material and exist only within a reporting year.
Recent Accounting Pronouncements and Accounting Changes
There are no new accounting pronouncements issued, but not yet adopted, that are expected to have a material impact on the Company’s results of operations, financial position or cash flow.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities, (ii) the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and (iii) the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Significant Accounting Policies
There have been no changes to the Company’s significant accounting policies as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

NOTE 2 – ACQUISITIONS
Acquisitions Completed in 2023
Acquisition of BlastersTrackless
On JanuaryApril 3, 2023, the Company completed the acquisition of substantially all the assets and operations of Blasters, Inc.Trackless Vehicles Limited and Blasters Technologies, LLCTrackless Vehicles Asset Corp, including the wholly-owned subsidiary Work Equipment Ltd. (collectively, “Blasters”“Trackless”), a leading U.S.Canadian manufacturer of truck-mounted waterblasting equipment.multi-purpose, off-road multi-purpose tractors and attachments. The Company expects that the BlastersTrackless acquisition will further bolster its position as an industry leading diversified industrial manufacturer of specialized vehicles for maintenance and infrastructure markets with leading brands of premium, value-adding products, and a strong supporting aftermarket platform.
The assets and liabilities of BlastersTrackless have been consolidated into the Company’s Condensed Consolidated Balance Sheet as of March 31,June 30, 2023, and the post-acquisition results of operations have been included in the Condensed Consolidated Statements of Operations, within the Environmental Solutions Group.
The initial cash consideration paid by the Company to acquire BlastersTrackless was $13.4C$57.3 million (approximately $42.6 million), inclusive of certain preliminary closing adjustments, and was funded through existing cash and borrowings under the Company’s credit agreement. In addition, there is a contingent earn-out payment of up to $8.0C$6.0 million (approximately $4.5 million), based upon the achievement of certain financial targets over a specified performance period. Any additional closing adjustments are expected to be finalized before the end of the third quarter of 2023.
The acquisition is being accounted for in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. Accordingly, the total purchase price has been allocated on a preliminary basis to assets acquired and liabilities assumed in connection with the acquisition based on their estimated fair values as of the completion of the acquisition. A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. The Company’s judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of operations. Due to the proximity of the date of acquisition to the date of issuance of the condensed consolidated financial statements, the Company’s purchase price allocation as of March 31,June 30, 2023 reflects various provisional estimates that were based on the information that was available as of the acquisition date and the filing date of this Form 10-Q. The Company believes that information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed; however, the determination of those fair values is not yet finalized. Thus, the preliminary measurements of fair value set forth in the table below are subject to change during the measurement period as valuations are finalized. The Company expects to finalize the valuation and complete the purchase price allocation as soon as practicable.

The acquisition is being accounted for in accordance with ASC 805, Business Combinations. The Company’s purchase price allocation as of June 30, 2023 reflects various provisional estimates that were based on the information that was available as of the acquisition date and the filing date of this Form 10-Q. The Company believes that information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed; however, the determination of those fair values is not yet finalized. Thus, the preliminary measurements of fair value set forth in the table below are subject to change during the measurement period as valuations are finalized. During the three months ended June 30, 2023, the Company recognized measurement period adjustments, which primarily resulted from obtaining a third-party valuation of acquired intangible assets, that resulted in a $7.2 million increase to the carrying value of Goodwill from the $12.9 million previously recorded as of December 31, 2022, with a corresponding reduction in the carrying value of acquired intangible assets. The measurement period adjustments did not have a material impact on the Company’s Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2023. The Company expects to finalize the valuation and complete the purchase price allocation as soon as practicable.

As more fully described within Note 13 – Fair Value Measurements, the Company uses a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The fair value of the Company’s borrowings and finance lease obligations is based on interest rates that we believe are currently available to us for issuance of debt with similar terms and remaining maturities (Level 2 input). The carrying amounts of the Company’s borrowings and finance lease obligations approximate their fair values as of March 31,June 30, 2023 and December 31, 2022.
The 2022 Credit Agreement is a senior secured credit facility which provides the Company and certain of its foreign subsidiaries access to an aggregate principal amount of $800 million, consisting of (i) a revolving credit facility in an amount up to $675 million (the “Revolver”) and (ii) a term loan facility in an amount up to $125 million.
Borrowings under the 2022 Credit Agreement bear interest, at the Company’s option, at a base rate or an Adjusted Term Secured Overnight Financing Rate (“SOFR”), Adjusted Eurocurrency Rate or Adjusted Daily Simple SONIA Rate (as each is defined in the 2022 Credit Agreement), plus, in each case, an applicable margin. The applicable margin ranges from zero to 0.75% for base rate borrowings and 1.00% to 1.75% for Adjusted Term SOFR, Adjusted Eurocurrency Rate or Adjusted Daily Simple SONIA Rate borrowings. The Company must also pay a commitment fee to the lenders ranging between 0.10% to 0.25% per annum on the unused portion of the $675 million Revolver along with other standard fees. Applicable margin, issuance fees and other customary expenses are payable on outstanding letters of credit.
The Company is subject to certain net leverage ratio and interest coverage ratio financial covenants under the 2022 Credit Agreement that are measured at each fiscal quarter-end. The Company was in compliance with all such covenants as of March 31,June 30, 2023.
As of March 31,June 30, 2023, there was $373.6$407.4 million of cash drawn and $11.2 million of undrawn letters of credit under the 2022 Credit Agreement, with $415.2$381.4 million of net availability for borrowings. As of December 31, 2022, there was $361.0 million cash drawn and $11.2 million of undrawn letters of credit under the 2022 Credit Agreement, with $427.8 million of net availability for borrowings.

Interest Rate Swaps
On October 21, 2022, the Company entered into an interest rate swap (the “2022 Swap”) with a notional amount of $75.0 million, as a means of fixing the floating interest rate component on $75.0 million of its variable-rate debt. The 2022 Swap is designated as a cash flow hedge, with an original maturity date of October 31, 2025.
As a result of the application of hedge accounting treatment, all unrealized gains and losses related to the derivative instrument are recorded in Accumulated other comprehensive loss and are reclassified into operations in the same period in which the hedged transaction affects earnings. Hedge effectiveness is assessed quarterly. The Company does not use derivative instruments for trading or speculative purposes.

Amortization expense for the six months ended June 30, 2023 and 2022 was $7.5 million and $6.5 million, respectively.
The Company currently estimates that aggregate amortization expense will be approximately $10.7$8.0 million for the remainder of 2023, $14.2$15.9 million in 2024, $14.2$15.9 million in 2025, $14.1$15.7 million in 2026, $13.1$14.5 million in 2027, and $39.7$37.9 million thereafter. Actual amounts of amortization may differ from estimated amounts due to acquisitions completed after the three months ended March 31, 2023, changes in foreign currency rates, measurement period adjustments for the TowHaulTrackless, Blasters, and BlastersTowHaul acquisitions, impairment of intangible assets and other events.
NOTE 7 – INCOME TAXES
For the three months ended March 31,June 30, 2023, the Company recognized income tax expense of $7.3$12.4 million, resulting in an effective tax rate of 21.0%23.5%. For the three months ended March 31,June 30, 2022, the Company recognized income tax expense of $7.1$11.1 million, resulting in an effective tax rate of 25.7%24.9%. The Company’s effective tax rate in the current-year quarter was lower than the prior-year quarter, primarily due to a $0.9$0.7 million increase in excess tax benefits associated with stock-based compensation activity.
For the six months ended June 30, 2023, the Company recognized income tax expense of $19.7 million, resulting in an effective tax rate of 22.5%. For the six months ended June 30, 2022, the Company recognized income tax expense of $18.2 million, resulting in an effective tax rate of 25.2%. The Company’s effective tax rate in the current-year period was lower than the prior-year period, primarily due to a $1.6 million increase in excess tax benefits associated with stock-based compensation activity and a $0.5 million benefit associated with changes in tax reserves.
During the threesix months ended March 31,June 30, 2023, the Company filed amended U.S. federal income tax returns for the 2015 through 2018 tax years to claim a worthless stock deduction. The aggregate refund claim associated with the worthless stock deduction was $13.2 million, including interest of $1.4 million, and the Company recognized an offsetting increase to its liability for unrecognized tax benefits.

NOTE 9 – COMMITMENTS AND CONTINGENCIES
Financial Commitments
The Company provides indemnifications and other guarantees in the ordinary course of business, the terms of which range in duration and often are not explicitly defined. Specifically, the Company is occasionally required to provide letters of credit and bid and performance bonds to various customers, principally to act as security for retention levels related to casualty insurance policies and to guarantee the performance of subsidiaries that engage in export and domestic transactions. At March 31,June 30, 2023, the Company had outstanding performance and financial standby letters of credit, as well as outstanding bid and performance

bonds, aggregating to $30.5$25.0 million. If any such letters of credit or bonds are called, the Company would be obligated to reimburse the issuer of the letter of credit or bond. The Company believes the likelihood of any currently outstanding letter of credit or bond being called is remote.
The Company has transactions involving the sale of equipment to certain of its customers which include (i) guarantees to repurchase the equipment for a fixed price at a future date and (ii) guarantees to repurchase the equipment from the third-party lender in the event of default by the customer. As of March 31,June 30, 2023, both the single year and maximum potential cash payments the Company could be required to make to repurchase equipment under these agreements amounted to $1.9 million. The Company’s risk under these repurchase arrangements would be partially mitigated by the value of the products repurchased as part of the transaction. Historical cash requirements and losses associated with these obligations have not been significant but could increase if customer defaults exceed current expectations.

The Company has certain lease agreements for facilities owned by affiliates which include provisions requiring the Company to guarantee any remaining lease payments in the event of default. As of March 31,June 30, 2023, the total amount of future payments guaranteed under these agreements was approximately $1.1$1.0 million. The Company believes the likelihood of defaulting on these leases is remote.
Product Warranties
The Company issues product performance warranties to customers with the sale of its products. The specific terms and conditions of these warranties vary depending upon the product sold and country in which the Company does business, with warranty periods generally ranging from one to five years. The Company estimates the costs that may be incurred under its basic limited warranty and records a liability in the amount of such costs at the time the sale of the related product is recognized. Factors that affect the Company’s warranty liability include (i) the number of units under warranty, (ii) historical and anticipated rates of warranty claims and (iii) costs per claim. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.
The following table summarizes the changes in the Company’s warranty liabilities during the threesix months ended March 31,June 30, 2023 and 2022:

Legal Proceedings
The Company is subject to various claims, including pending and possible legal actions for product liability and other damages, and other matters arising in the ordinary course of the Company’s business. On a quarterly basis, the Company reviews uninsured material legal claims against the Company and accrues for the costs of such claims as appropriate in the exercise of management’s best judgment and experience. However, due to a lack of factual information available to the Company about a claim, or the procedural stage of a claim, it may not be possible for the Company to reasonably assess either the probability of a favorable or unfavorable outcome of the claim or to reasonably estimate the amount of loss should there be an unfavorable outcome. Therefore, for many claims, the Company cannot reasonably estimate a range of loss.
The Company believes, based on current knowledge and after consultation with counsel, that the outcome of such claims and actions will not have a material adverse effect on the Company’s results of operations or financial condition. However, in the event of unexpected future developments, it is possible that the ultimate resolution of such matters, if unfavorable, could have a material adverse effect on the Company’s results of operations, financial condition or cash flow.
Hearing Loss Litigation
The Company has been sued for monetary damages by firefighters who claim that exposure to the Company’s sirens has impaired their hearing and that the sirens are therefore defective. There were 33 cases filed during the period of 1999 through 2004, involving a total of 2,443 plaintiffs, in the Circuit Court of Cook County, Illinois. These cases involved more than 1,800

firefighter plaintiffs from locations outside of Chicago. In 2009, six additional cases were filed in Cook County, involving 299 Pennsylvania firefighter plaintiffs. During 2013, another case was filed in Cook County involving 74 Pennsylvania firefighter plaintiffs.
The trial of the first 27 of these plaintiffs’ claims occurred in 2008, whereby a Cook County jury returned a unanimous verdict in favor of the Company.
An additional 40 Chicago firefighter plaintiffs were selected for trial in 2009. Plaintiffs’ counsel later moved to reduce the number of plaintiffs from 40 to nine. The trial for these nine plaintiffs concluded with a verdict against the Company and for the plaintiffs in varying amounts totaling $0.4 million. The Company appealed this verdict. On September 13, 2012, the Illinois Appellate Court rejected this appeal. The Company thereafter filed a petition for rehearing with the Illinois Appellate Court, which was denied on February 7, 2013. The Company sought further review by filing a petition for leave to appeal with the

Illinois Supreme Court on March 14, 2013. On May 29, 2013, the Illinois Supreme Court issued a summary order declining to accept review of this case. On July 1, 2013, the Company satisfied the judgments entered for these plaintiffs, which resulted in final dismissal of these cases.
A third consolidated trial involving eight Chicago firefighter plaintiffs occurred during November 2011. The jury returned a unanimous verdict in favor of the Company at the conclusion of this trial.
Following this trial, on March 12, 2012 the trial court entered an order certifying a class of the remaining Chicago Fire Department firefighter plaintiffs for trial on the sole issue of whether the Company’s sirens were defective and unreasonably dangerous. The Company petitioned the Illinois Appellate Court for interlocutory appeal of this ruling. On May 17, 2012, the Illinois Appellate Court accepted the Company’s petition. On June 8, 2012, plaintiffs moved to dismiss the appeal, agreeing with the Company that the trial court had erred in certifying a class action trial in this matter. Pursuant to plaintiffs’ motion, the Illinois Appellate Court reversed the trial court’s certification order.
Thereafter, the trial court scheduled a fourth consolidated trial involving three firefighter plaintiffs, which began in December 2012. Prior to the start of this trial, the claims of two of the three firefighter plaintiffs were dismissed. On December 17, 2012, the jury entered a complete defense verdict for the Company.
Following this defense verdict, plaintiffs again moved to certify a class of Chicago Fire Department plaintiffs for trial on the sole issue of whether the Company’s sirens were defective and unreasonably dangerous. Over the Company’s objection, the trial court granted plaintiffs’ motion for class certification on March 11, 2013 and scheduled a class action trial to begin on June 10, 2013. The Company filed a petition for review with the Illinois Appellate Court on March 29, 2013 seeking reversal of the class certification order.
On June 25, 2014, a unanimous three-judge panel of the First District Illinois Appellate Court issued its opinion reversing the class certification order of the trial court. Specifically, the Appellate Court determined that the trial court’s ruling failed to satisfy the class-action requirements that the common issues of the firefighters’ claims predominate over the individual issues and that there is an adequate representative for the class. During a status hearing on October 8, 2014, plaintiffs represented to the Court that they would again seek to certify a class of firefighters on the issue of whether the Company’s sirens were defective and unreasonably dangerous. On January 12, 2015, plaintiffs filed motions to amend their complaints to add class action allegations with respect to Chicago firefighter plaintiffs, as well as the approximately 1,800 firefighter plaintiffs from locations outside of Chicago. On March 11, 2015, the trial court granted plaintiffs’ motions to amend their complaints. On April 24, 2015, the cases were transferred to Cook County chancery court to decide the class certification issues. On March 23, 2018, plaintiffs filed a motion to certify as a class all firefighters from the Chicago Fire Department who have filed lawsuits in this matter. The Company objected to certification and the parties engaged in discovery and other matters related to this motion.

Thereafter, on December 20, 2021, the parties executed a settlement agreement to resolve claims of approximately 462 firefighters still involved in the Cook County litigation, as well as the DuPage County litigation discussed below. Under the
terms of the settlement agreement, the Company agreed to pay a lump sum of $0.2 million to resolve the claims of these firefighters. The estimated settlement amount was accrued by the Company. The Company agreed to pay this lump sum amount based upon its assessment of firefighters who meet minimal bilateral hearing loss standards, which is a subset of the larger group referenced above. The settlement agreement did not require the payment of any attorney fees by the Company. The settlement agreement also provided that plaintiffs’ attorney would withdraw from representing firefighters who do not agree to the settlement. The Company had discretion to void the settlement agreement if less than 93% of these firefighters agreed to settle their claims; the settlement agreement would also be voided if less than 70% of eligible firefighters agreed to the settlement. The settlement agreement was subject to review and approval by the Court. In July 2022, the Company issued the $0.2

(Unaudited)
$0.2 million settlement payment for eligible plaintiffs who submitted a release. The claims of all other eligible plaintiffs were dismissed for want of prosecution on August 5, 2022.
The Company also filed motions to dismiss cases involving firefighters who worked for fire departments located outside of the State of Illinois based on improper venue. On February 24, 2017, the Circuit Court of Cook County entered orders dismissing the cases of 1,770 such firefighter plaintiffs from the jurisdiction of the State of Illinois. Pursuant to these orders, these plaintiffs had six months thereafter to refile their cases in jurisdictions where these firefighters are located. Prior to this six-month deadline, attorneys representing some of these plaintiffs contacted the Company regarding possible settlement of their cases. During the year ended December 31, 2017, the Company entered into a global settlement agreement with two attorneys who represented approximately 1,090 of these plaintiffs. Under the terms of the settlement agreement, the Company offered $700 per plaintiff to settle these cases and 717 plaintiffs accepted this offer as a final settlement. The settlement agreement did

not require the payment of any attorney fees by the Company. The attorneys representing these plaintiffs agreed to withdraw from representing plaintiffs who did not respond to the settlement offer. It is the Company’s position that the non-settling plaintiffs who failed to timely refile their cases following the February 2017 dismissal by the Circuit Court of Cook County are now barred from doing so by the statute of limitations. The Company filed a venue motion seeking to transfer to DuPage County cases involving 10 plaintiffs who reside and work in Illinois but outside of Cook County. The Court granted this motion on June 28, 2017.
The Company was also sued on this issue outside of the Cook County, Illinois venue. Between 2007 and 2009, a total of 71 lawsuits involving 71 plaintiffs were filed in the Court of Common Pleas, Philadelphia County, Pennsylvania. Three of these cases were dismissed pursuant to pretrial motions filed by the Company. Another case was voluntarily dismissed. Prior to trial in four cases, the Company paid nominal sums to obtain dismissals.
Three trials occurred in Philadelphia involving these cases filed in 2007 through 2009. The first trial involving one of these plaintiffs occurred in 2010, when the jury returned a verdict for the plaintiff. The jury found that the Company’s siren was not defectively designed, but that the Company negligently constructed the siren. The jury awarded damages in the amount of less than $0.1 million. The Company appealed this verdict. Another trial, involving nine Philadelphia firefighter plaintiffs, also occurred in 2010 when the jury returned a defense verdict for the Company as to all claims and all plaintiffs involved in that trial. The third trial, also involving nine Philadelphia firefighter plaintiffs, was completed during 2010 when the jury returned a defense verdict for the Company as to all claims and all plaintiffs involved in that trial.
Following defense verdicts in the last two Philadelphia trials, the Company negotiated settlements with respect to all remaining filed cases in Philadelphia at that time, as well as other firefighter claimants represented by the attorney who filed the Philadelphia cases. On January 4, 2011, the Company entered into a Global Settlement Agreement (the “Settlement Agreement”) with the law firm of the attorney representing the Philadelphia claimants, on behalf of 1,125 claimants the firm represented (the “Claimants”) and who had asserted product claims against the Company (the “Claims”). Three hundred eight of the Claimants had lawsuits pending against the Company in Cook County, Illinois.
The Settlement Agreement provided that the Company pay a total amount of $3.8 million (the “Settlement Payment”) to settle the Claims (including the costs, fees and other expenses of the law firm in connection with its representation of the Claimants), subject to certain terms, conditions and procedures set forth in the Settlement Agreement. In order for the Company to be required to make the Settlement Payment: (i) each Claimant who agreed to settle his or her claims had to sign a release acceptable to the Company (a “Release”), (ii) each Claimant who agreed to the settlement and who was a plaintiff in a lawsuit, had to dismiss his or her lawsuit with prejudice, (iii) by April 29, 2011, at least 93% of the Claimants identified in the Settlement Agreement must have agreed to settle their claims and provide a signed Release to the Company and (iv) the law firm had to withdraw from representing any Claimants who did not agree to the settlement, including those who filed lawsuits. If the conditions to the settlement were met, but less than 100% of the Claimants agreed to settle their Claims and sign a Release, the Settlement Payment would be reduced by the percentage of Claimants who did not agree to the settlement.
On April 22, 2011, the Company confirmed that the terms and conditions of the Settlement Agreement had been met and made a payment of $3.6 million to conclude the settlement. The amount was based upon the Company’s receipt of 1,069 signed releases provided by Claimants, which was 95% of all Claimants identified in the Settlement Agreement.
The Company generally denies the allegations made in the claims and lawsuits by the Claimants and denies that its products caused any injuries to the Claimants. Nonetheless, the Company entered into the Settlement Agreement for the purpose of minimizing its expenses, including legal fees, and avoiding the inconvenience, uncertainty and distraction of the claims and lawsuits.

During April through October 2012, 20 new cases were filed in the Court of Common Pleas, Philadelphia County, Pennsylvania. These cases were filed on behalf of 20 Philadelphia firefighters and involved various defendants in addition to the Company. Five of these cases were subsequently dismissed. The first trial involving these 2012 Philadelphia cases occurred during December 2014 and involved three firefighter plaintiffs. The jury returned a verdict in favor of the Company. Following this trial, all of the parties agreed to settle cases involving seven firefighter plaintiffs set for trial during January 2015 for nominal amounts per plaintiff.
In January 2015, plaintiffs’ attorneys filed two new complaints in the Court of Common Pleas, Philadelphia, Pennsylvania on behalf of approximately 70 additional firefighter plaintiffs. The vast majority of the firefighters identified in these complaints were located outside of Pennsylvania. One of the complaints in these cases, which involved 11 firefighter plaintiffs from the District of Columbia, was removed to federal court in the Eastern District of Pennsylvania. Plaintiffs voluntarily dismissed all

claims in this case on May 31, 2016. The Company thereafter moved to recover various fees and costs in this case, asserting that plaintiffs’ counsel failed to properly investigate these claims prior to filing suit. The Court granted this motion on April 25, 2017, awarding $0.1 million to the Company (the “Order”). After plaintiffs appealed this Order, the United States Court of Appeals for the Third Circuit affirmed the lower court decision awarding fees and costs to the Company.
With respect to claims of other out-of-state firefighters involved in these two cases, the Company moved to dismiss these claims as improperly filed in Pennsylvania. The Court granted this motion and dismissed these claims on November 5, 2015. During August through December 2015, another nine new cases were filed in the Court of Common Pleas, Philadelphia County, Pennsylvania. These cases involved a total of 193 firefighters, most of whom were located outside of Pennsylvania. The Company again moved to dismiss all claims filed by out-of-state firefighters in these cases as improperly filed in Pennsylvania. On May 24, 2016, the Court granted this motion and dismissed these claims. Plaintiffs appealed this decision and, on September 25, 2018, the appellate court reversed this dismissal. The Company then filed a petition with the appellate court requesting that the court reconsider its ruling. On December 7, 2018, the appellate court granted the Company’s petition and withdrew its prior decision. On June 25, 2020, the Court issued a decision affirming the trial court’s dismissal of these cases with prejudice.
On May 13, 2016, four new cases were filed in Philadelphia state court, involving a total of 55 Philadelphia firefighters who live in Pennsylvania. During August 2016, the Company settled a case for nominal amounts involving four Philadelphia firefighters that had been set for trial in Philadelphia state court during September 2016. During 2017, plaintiffs filed additional cases in the Court of Common Pleas, Philadelphia County, involving over 100 Philadelphia firefighter plaintiffs. During January 2017, plaintiffs filed a motion to consolidate and bifurcate, similar to a motion filed in the Pittsburgh hearing loss cases, as described below. The Company filed an opposition to this motion. These cases were then transferred to the mass tort program in Philadelphia for pretrial purposes. Plaintiffs’ counsel thereafter dismissed several plaintiffs. During November 2017, a trial involving one Philadelphia firefighter occurred. The jury returned a verdict in favor of the Company in this trial. Prior to a dismissal of these cases pursuant to the Tolling Agreement, discussed below, there was a total of 75 firefighters involved in cases pending in the Philadelphia mass tort program.
During March 2014, an action also was brought in the Court of Common Pleas of Erie County, Pennsylvania on behalf of 61 firefighters. This case likewise involves various defendants in addition to the Company. After the Company filed pretrial motions, 33 Erie County firefighter plaintiffs voluntarily dismissed their claims. Prior to a dismissal of these cases pursuant to the Tolling Agreement, discussed below, there was a total of 28 firefighters involved in cases filed in Erie County.
During August 2017, five cases involving 70 firefighter plaintiffs were filed in Lackawanna County, Pennsylvania. These cases involve firefighter plaintiffs who originally filed in Cook County several years ago and were dismissed pursuant to the Company’s forum non conveniens motion.
On September 17, 2014, 20 lawsuits, involving a total of 193 Buffalo Fire Department firefighters, were filed in the Supreme Court of the State of New York, Erie County. All of the cases filed in Erie County, New York were removed to federal court in the Western District of New York. Plaintiffs filed a motion to consolidate and bifurcate these cases, similar to the motion filed in the Pittsburgh hearing loss cases, as described below. The Company filed an opposition to the motion. During February 2015, a lawsuit involving one New York City firefighter plaintiff was filed in the Supreme Court of the State of New York, New York County. The plaintiff named the Company as well as several other parties as defendants. That case subsequently was transferred to federal court in the Northern District of New York and thereafter dismissed. During April 2015 through January 2016, 29 new cases involving a total of 235 firefighters were filed in various counties in the New York City area. During December 2016 through October 2017, additional cases were filed in these jurisdictions. On February 5, 2018, the Company was served with a complaint in an additional case filed in Kings County, New York. This case involved one plaintiff. Prior to a

dismissal of these cases pursuant to the Tolling Agreement, discussed below, there was a total of 536 firefighters involved in cases filed in the State of New York.
During November 2015, the Company was served with a complaint filed in Union County, New Jersey state court, involving 34 New Jersey firefighters. This case was transferred to federal court in the District of New Jersey. During the period from January through May 2016, eight additional cases were filed in various New Jersey state courts. Most of the firefighters in these cases resided in New Jersey and worked at New Jersey fire departments. During December 2016, a case involving one New Jersey firefighter was filed in the United States District Court of New Jersey. On May 2, 2017, plaintiffs filed a motion to consolidate and bifurcate in the pending federal court case in New Jersey. This motion was similar to bifurcation motions filed by plaintiffs in Pittsburgh, Buffalo and Philadelphia. The Court denied the motion as premature. Pursuant to a petition filed by both parties,

all New Jersey state court cases were consolidated for pretrial purposes. Prior to a dismissal of these cases pursuant to the Tolling Agreement, discussed below, there were a total of 61 firefighters involved in cases filed in New Jersey.
During May through October 2016, nine cases were filed in Suffolk County, Massachusetts state court, naming the Company as a defendant. These cases involved 194 firefighters who lived and worked in the Boston area. During August 2017, plaintiffs filed additional cases in Suffolk County court. The Company moved to transfer various cases filed in Suffolk County to other counties in Massachusetts where plaintiffs resided and worked. Prior to a dismissal of these cases pursuant to the Tolling Agreement, discussed below, there was a total of 218 firefighters involved in cases filed in Massachusetts.
During August and September 2017, plaintiffs’ attorneys filed additional hearing loss cases in Florida. The Company was the only named defendant. These cases were filed in several different counties in Florida, including Tampa, Miami and Orlando municipalities. Prior to a dismissal of these cases pursuant to the Tolling Agreement, discussed below, there was a total of 166 firefighters involved in cases filed in Florida.
During April through July 2013, additional cases were filed in Allegheny County, Pennsylvania on behalf of 247 plaintiff firefighters from Pittsburgh and against various defendants, including the Company. During May 2016, two additional cases were filed against the Company in Allegheny County involving 19 Pittsburgh firefighters. After the Company filed pretrial motions, the Court dismissed claims of 55 Pittsburgh firefighter plaintiffs. The Court scheduled trials for May, September and November 2016, for eight firefighters per trial. Prior to the first scheduled trial in Pittsburgh, the Court granted the Company’s motion for summary judgment and dismissed all claims asserted by plaintiff firefighters involved in this trial. Following an appeal by the plaintiff firefighters, the appellate court affirmed this dismissal. The next trial for six Pittsburgh firefighters started on November 7, 2016. Shortly after this trial began, plaintiffs’ counsel moved for a mistrial because a key witness suddenly became unavailable. The Court granted this motion and rescheduled this trial for March 6, 2017. During January 2017, plaintiffs also moved to consolidate and bifurcate trials involving Pittsburgh firefighters. In particular, plaintiffs sought one trial involving liability issues to apply to all Pittsburgh firefighters who filed suit against the Company. The Company filed an opposition to this motion. On April 18, 2017, the trial court granted plaintiffs’ motion to bifurcate the next Pittsburgh trial. Pursuant to a motion for clarification filed by the Company, the Court ruled that the bifurcation order would only apply to six plaintiffs who were part of the next trial group in Pittsburgh. The Company thereafter sought an interlocutory appeal of the Court’s bifurcation order. The appellate court declined to accept the appeal at that time. A bifurcated trial began on September 27, 2017 in Allegheny County, Pennsylvania. Prior to and during trial, two plaintiffs were dismissed, resulting in four plaintiffs remaining for trial. After approximately two weeks of trial, the jury found that the Company’s siren product was not defective or unreasonably dangerous and rendered a verdict in favor of the Company.
A second trial involving Pittsburgh firefighters began during January 2018. At the outset of this trial, plaintiffs’ attorneys, who represent all firefighters who have filed cases in Allegheny County, Philadelphia, Buffalo, New Jersey, Massachusetts, and Florida, as described above, requested that the Company consider settlement of various cases. This trial was continued to allow the parties to further discuss possible settlement. During March 2018, the parties agreed in principle on a framework (the “Settlement Framework”) to resolve hearing loss claims and cases in all jurisdictions involved in the hearing loss litigation except in Cook County and Lackawanna County, and excluding one case involving one firefighter in New York City. The firefighters excluded from the Settlement Framework are represented by different attorneys. The Company settled the cases in Lackawanna County and settled the case involving one firefighter in New York City for nominal amounts. Pursuant to the Settlement Framework, the Company would pay $700 to each firefighter who filed a lawsuit and is eligible to be part of the settlement. The Company would pay $300 to each firefighter who has not yet filed a case and is eligible to be part of the settlement. The settlement agreement does not include the payment of any attorney fees by the Company. To be eligible for settlement, among other things, firefighters must provide proof that they have high frequency noise-induced hearing loss. There are approximately 2,160 firefighters whose claims may be considered as part of this settlement, including approximately 921 firefighters who have ongoing filed lawsuits. This Settlement Framework was finalized in a global settlement agreement

executed on November 4, 2019. Pursuant to this global settlement agreement, the parties are now in the process of determining how many of the approximately 2,160 firefighters will be eligible to participate in the settlement. In order to minimize the parties’ respective legal costs and expenses during this settlement process, on July 5, 2018, the parties entered into a tolling agreement (the “Tolling Agreement”). Pursuant to the Tolling Agreement, counsel for the settling firefighters agreed to dismiss the pending lawsuits in all jurisdictions except for the Allegheny County (Pittsburgh), Pennsylvania cases, and the Company agreed to a tolling of any statute of limitations applicable to the dismissed cases. The Tolling Agreement continued in place until the parties executed the global settlement agreement on November 4, 2019. After execution of the global settlement agreement, the Allegheny County (Pittsburgh) cases were dismissed. The global settlement agreement requires plaintiffs’ attorneys to withdraw from representing firefighters who elect not to participate in this settlement.

As of March 31,June 30, 2023, the Company has recognized an estimated liability for the potential settlement amount under the Settlement Framework. While it is reasonably possible that the ultimate resolution of this matter may result in a loss in excess of the amount accrued, the incremental loss is not expected to be material.
From 2007 through 2009, firefighters also brought hearing loss claims against the Company in New Jersey, Missouri, Maryland and Kings County, New York. All of those cases, however, were dismissed prior to trial, including four cases in the Supreme Court of Kings County, New York that were dismissed upon the Company’s motion in 2008. On appeal, the New York appellate court affirmed the trial court’s dismissal of these cases.
NOTE 10 – EARNINGS PER SHARE
The Company computes earnings per share (“EPS”) in accordance with ASC 260, Earnings per Share, which requires that non-vested restricted stock containing non-forfeitable dividend rights should be treated as participating securities pursuant to the two-class method. Under the two-class method, net income is reduced by the amount of dividends declared in the period for common stock and participating securities. The remaining undistributed earnings are then allocated to common stock and participating securities as if all of the net income for the period had been distributed. The amounts of distributed and undistributed earnings allocated to participating securities for the three and six months ended March 31,June 30, 2023 and 2022 were insignificant and did not materially impact the calculation of basic or diluted EPS.
Basic EPS is computed by dividing income available to common stockholders by the weighted average number of shares of common stock and non-vested restricted stock awards outstanding for the period.
Diluted EPS is computed using the weighted average number of shares of common stock and non-vested restricted stock awards outstanding for the year, plus the effect of dilutive potential common shares outstanding during the period. The dilutive effect of common stock equivalents is determined using the more dilutive of the two-class method or alternative methods. The Company uses the treasury stock method to determine the potentially dilutive impact of our employee stock options and restricted stock units, and the contingently issuable method for our performance-based restricted stock unit awards.
For the three and six months ended March 31,June 30, 2023, the number of options to purchase 0.1 million and 0.0 million shares, respectively, of the Company’s common stock that had an antidilutiveanti-dilutive effect on EPS, was immaterial.and accordingly, were excluded from the calculation of diluted EPS. For the three and six months ended March 31,June 30, 2022, options to purchase 0.3 million and 0.2 million shares, respectively, of the Company’s common stock had an anti-dilutive effect on EPS, and accordingly, were excluded from the calculation of diluted EPS.

NOTE 13 – FAIR VALUE MEASUREMENTS
The Company uses a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs are developed based on market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about valuation based on the best information available in the circumstances. The three levels of inputs are classified as follows:
Level 1 — quoted prices in active markets for identical assets or liabilities;
Level 2 — observable inputs, other than quoted prices included in Level 1, such as quoted prices for markets that are not active, or other inputs that are observable or can be corroborated by observable market data; and
Level 3 — unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities, including certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

In determining fair value, the Company uses various valuation approaches within the fair value measurement framework. The valuation methodologies used for the Company’s assets and liabilities measured at fair value and their classification in the valuation hierarchy are summarized below.
Cash Equivalents
Cash equivalents primarily consist of time-based deposits and interest-bearing instruments with maturities of three months or less. The Company classified cash equivalents as Level 1 due to the short-term nature of these instruments and measured the fair value based on quoted prices in active markets for identical assets.
Interest Rate Swaps
As described in Note 5 – Debt, the Company may, from time to time, execute interest rate swaps as a means of fixing the floating interest rate component on a portion of its floating-rate debt. The Company classifies its interest rate swaps as Level 2 due to the use of a discounted cash flow model based on the terms of the contract and the interest rate curve (Level 2 inputs) to calculate the fair value of the swaps.
Contingent Consideration
At March 31,June 30, 2023, the Company had contingent obligations to transfer up to $7.5 million, and $8.0 million, and C$6.0 million (approximately $4.5 million), to the former owners of Deist Industries, Inc. and certain of its affiliates (collectively, “Deist”), Blasters, and Blasters,Trackless, respectively, if specified financial results are met over future reporting periods (i.e., an earn-out). The Deist, Blasters, and BlastersTrackless acquisitions were completed on December 30, 2021, January 3, 2023, and JanuaryApril 3, 2023, respectively. The Deist and Trackless contingent earn-out payment,payments, if earned, would be due to be paid following the third anniversary of the closing date. The Blasters contingent earn-out payments, if earned, would be due to paid annually, in each of the three years following the anniversary of the closing date. During the threesix months ended March 31,June 30, 2023, the Company paid $0.5 million to settle the contingent consideration obligation due to the former owners of Mark Rite Lines Equipment Company, Inc. (“MRL”), which was acquired on July 1, 2019.
Liabilities for contingent consideration are measured at fair value each reporting period, with the acquisition-date fair value included as part of the consideration transferred. Subsequent changes in fair value are included as a component of Acquisition and integration-related expenses (benefits) on the Condensed Consolidated Statements of Operations.
The Company uses an income approach to value the contingent consideration liability based on the present value of risk-adjusted future cash flows under either a scenario-based or option-pricing method, as appropriate. Due to the lack of relevant observable market data over fair value inputs, such as prospective financial information or probabilities of future events as of March 31,June 30, 2023, the Company has classified the contingent consideration liability within Level 3 of the fair value hierarchy outlined in ASC 820, Fair Value Measurements. As further described in Note 2 – Acquisitions, the Company has recognized a preliminary estimate of the fair value of the Blasters and Trackless contingent consideration liabilityliabilities as of the applicable acquisition date, which isdate. Such preliminary estimates are subject to change during the measurement period as the applicable third-party valuation isvaluations are finalized.

NOTE 14 – SUBSEQUENT EVENTS
Acquisition of Trackless
On April 3, 2023, the Company completed the acquisition of substantially all the assets and operations of Trackless Vehicles Limited and Trackless Vehicles Asset Corp, including the wholly-owned subsidiary Work Equipment Ltd. (collectively, “Trackless”) for an initial purchase price of C$54.0 million (approximately $40.0 million). The initial purchase price, which is subject to certain post-closing adjustments, was funded through existing cash and borrowings under the Company’s revolving credit facility. In addition, there is a contingent earn-out payment of up to C$6.0 million (approximately $4.4 million), based upon the achievement of certain financial targets over a specified performance period.
Trackless is a leading Canadian manufacturer of multi-purpose, off-road municipal tractors and attachments. The Company expects that the Trackless acquisition will further bolster its position as an industry leading diversified industrial manufacturer of specialized vehicles for maintenance and infrastructure markets with leading brands of premium, value-adding products, and a strong supporting aftermarket platform.
The preliminary purchase price allocation has not been completed at this time due to the proximity of the date of acquisition to the date of issuance of the condensed consolidated financial statements. The post-acquisition operating results of Trackless are expected to be included within the Environmental Solutions Group.

Cost of sales for the six months ended June 30, 2023 increased by $74.2 million, or 16%, compared to the prior-year period, primarily related to higher sales volumes and additional costs from the TowHaul, Blasters, and Trackless acquisitions and increases in chassis costs, partially offset by a $4.4 million favorable foreign currency translation impact. Gross profit margin for the six months ended June 30, 2023 was 23.0%, compared to 21.1% in the prior-year period, with the improvement primarily attributable to improved operating leverage from higher sales volumes and benefits from pricing actions, partially offset by an increase in lower margin chassis sales.
SEG&A expenses for the six months ended June 30, 2023 increased by $7.6 million, or 15%, compared to the prior-year period, primarily due to additional costs from the TowHaul, Blasters, and Trackless acquisitions, as well as increases in sales commissions and incentive-based compensation expenses. As a percentage of net sales, SEG&A expenses were 8.3% in the current-year period, down from 8.6% in the prior-year period.
Operating income for the six months ended June 30, 2023 increased by $27.9 million, or 42%, compared to the prior-year period, largely due to a $37.1 million improvement in gross profit, partially offset by the $7.6 million increase in SEG&A expenses, a $1.0 million increase in amortization expense, and a $0.6 million increase in acquisition and integration-related costs.
Backlog was $902$940 million at March 31,June 30, 2023, compared to $690$734 million at March 31,June 30, 2022.

Seasonality of Company’s Business
Certain of the Company’s businesses are susceptible to the influences of seasonal factors, including buying patterns, delivery patterns and productivity influences from holiday periods and weather. In general, the Company tends to have lower equipment sales in the first calendar quarter of each year compared to other quarters as a result of these factors. In addition, rental income and parts sales are generally higher in the second and third quarters of the year, because many of the Company’s products are used for maintenance activities in North America, where usage is typically lower during periods of harsher weather conditions.

Financial Condition, Liquidity and Capital Resources
The Company uses its cash flow from operations to fund growth and to make capital investments that sustain its operations, reduce costs, or both. Beyond these uses, remaining cash is used to pay down debt, repurchase shares, fund dividend payments and make pension contributions. The Company may also choose to invest in the acquisition of businesses. In the absence of significant unanticipated cash demands, we believe that the Company’s existing cash balances, cash flow from operations and borrowings available under the Company’s credit facility will provide funds sufficient for these purposes. As of March 31,June 30, 2023, there was $373.6$407.4 million of cash drawn and $11.2 million of undrawn letters of credit under the 2022 Credit Agreement, with $415.2$381.4 million of availability for borrowings. The net cash flows associated with the Company’s rental equipment transactions are included in cash flow from operating activities.
The Company’s cash and cash equivalents totaled $38.4$48.8 million and $47.5 million as of March 31,June 30, 2023 and December 31, 2022, respectively. As of March 31,June 30, 2023, $15.9$22.3 million of cash and cash equivalents was held by foreign subsidiaries. Cash and cash equivalents held by subsidiaries outside the U.S. typically are held in the currency of the country in which it is located. The Company uses this cash to fund the operating activities of its foreign subsidiaries and for further investment in foreign operations. Generally, the Company has considered such cash to be permanently reinvested in its foreign operations and the Company’s current plans do not demonstrate a need to repatriate such cash to fund U.S. operations. However, in the event that these funds are needed to fund U.S. operations or to satisfy U.S. obligations, they generally could be repatriated. The repatriation of these funds may cause the Company to incur additional U.S. income tax expense, dependent on income tax laws and other circumstances at the time any such amounts are repatriated.
Net cash of $7.1$43.0 million was provided by operating activities in the threesix months ended March 31,June 30, 2023, compared to $7.0$22.4 million in the prior-year period, with the year-over-year changeincrease primarily due to working capital improvements and higher net income, partially offset by increased rental fleet investments to support seasonal demand.strong demand for rentals and used equipment and higher tax payments.

During the threesix months ended March 31,June 30, 2023, the Company also paid $0.5 million to settle the contingent consideration obligation due to the former owners of MRL.MRL, and received $2.0 million from stock option exercises.

Item 3.     Quantitative and Qualitative Disclosures about Market Risk.
See Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. During the threesix months ended March 31,June 30, 2023, there have been no significant changes in our exposure to market risk.
Item 4.     Controls and Procedures.
As required by Rule 13a-15 under the Exchange Act, the Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Exchange Act) as of March 31,June 30, 2023. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of March 31,June 30, 2023.
As a matter of practice, the Company’s management continues to review and document internal control and procedures for financial reporting. From time to time, the Company may make changes aimed at enhancing the effectiveness of the controls and ensuring that the systems evolve with the business. SEC guidance permits management to omit an assessment of internal control over financial reporting for an acquired business from management’s assessment of internal control over financial reporting for a period not to exceed one year from the date of the acquisition. During the threesix months ended March 31,June 30, 2023, the Company completed the acquisitionacquisitions of Trackless and Blasters. As of March 31,June 30, 2023, management has not yet fully assessed Trackless’ or Blasters’ internal control over financial reporting. Excluding the acquisitionacquisitions of Trackless and Blasters, there were no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting during the threesix months ended March 31,June 30, 2023.
