FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K (“Form 10-K”) 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, but are not limited to, the risk factors 
described under Item 1A, Risk Factors as set forth in Part I, as well as those discussed elsewhere in this Form 10-K and in our 
subsequently filed documents, as applicable. 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. 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-K.

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

PART I

Item 1.    Business.

Federal Signal Corporation, founded in 1901, was reincorporated as a Delaware corporation in 1969. The Company designs,  
manufactures and supplies a suite of products and integrated solutions for municipal, governmental, industrial and commercial 
customers. The Company’s portfolio of products that it manufactures includes (i) vehicles and equipment for maintenance and 
infrastructure end-markets, including sewer cleaners, industrial vacuum loaders, vacuum- and hydro-excavation trucks 
(collectively, “safe-digging trucks”), street sweepers, waterblasting equipment, road-marking and line-removal equipment, 
dump truck bodies, trailers, metal extraction support equipment and multi-purpose tractors, and (ii) public safety equipment, 
such as vehicle lightbars and sirens, industrial signaling equipment, public warning systems and general alarm/public address 
systems. In addition, the Company engages in the sale of parts, service and repair, equipment rentals and training as part of a 
comprehensive aftermarket offering to its customers. The Company operates 23 principal manufacturing facilities in five 
countries and provides products and integrated solutions to customers in all regions of the world.

Narrative Description of Business

Products manufactured and supplied, and services rendered, by the Company are divided into two reportable segments: the 
Environmental Solutions Group and the Safety and Security Systems Group. The individual operating businesses are organized 
as such because they share certain characteristics, including technology, marketing, distribution and product application, which 
create long-term synergies. Corporate contains those items that are not included in the Company’s reportable segments.

Financial information concerning the Company’s two reportable segments for each of the three years in the period ended 
December 31, 2023, is included in Note 17 – Segment Information to the accompanying consolidated financial statements and 
is incorporated herein by reference.

During the year ended December 31, 2023, the Company completed the acquisitions of substantially all of the assets and 
operations of Trackless Vehicles Limited and Trackless Vehicles Asset Corp, and the wholly-owned subsidiary Work 
Equipment Ltd. (collectively, “Trackless”) and substantially all of the assets and operations of Blasters, Inc. and Blasters 
Technologies, LLC (collectively, “Blasters”). 

Environmental Solutions Group

The Company’s Environmental Solutions Group is a leading manufacturer and supplier of a full range of street sweepers, sewer 
cleaners, industrial vacuum loaders, safe-digging trucks, high-performance waterblasting equipment, road-marking and line-
removal equipment, dump truck bodies, trailers, metal extraction support equipment and multi-purpose tractors. The Group 
manufactures vehicles and equipment in the U.S. and Canada that are sold under the Elgin®, Vactor®, Guzzler®, TRUVAC®, 
WestechTM, Jetstream®, Blasters, Mark Rite Lines, Trackless, Ox Bodies®, Crysteel®, J-Craft®, Duraclass®, Rugby®, Travis®, 
OSW, NTE, WTB, Ground Force, TowHaul®, Bucks® and Switch-N-Go® brand names. The Group’s product offerings also 
include certain products manufactured by other companies, such as refuse and recycling collection vehicles. Products are sold to 
both municipal and industrial customers either through a dealer network or direct sales to service customers generally 
depending on the type and geographic location of the customer. In addition to vehicle and equipment sales, the Group also 
engages in the sale of parts, service and repair, equipment rentals and training as part of a comprehensive aftermarket offering 
to its current and potential customers through its service centers located across North America.

Under the Elgin brand name, the Company sells a leading U.S. brand of street sweepers primarily designed for large-scale 
cleaning of curbed streets, parking lots and other paved surfaces utilizing mechanical sweeping, vacuum and recirculating air 
technology. Vactor is a leading manufacturer of equipment solutions for cleaning and maintaining sewers and catch basins. 
Under the TRUVAC brand name, the Company manufactures a range of premium vacuum- and hydro-excavation trucks 
designed to satisfy the safe-digging requirements of businesses or organizations that locate and verify underground utility lines 
and pipes. Guzzler is a leader in industrial vacuum loaders used to manage industrial waste or recover and recycle valuable raw 
materials. Westech is a manufacturer of high-quality, rugged vacuum-excavation trucks. Jetstream manufactures high-pressure 
waterblasting equipment and accessories for commercial and industrial cleaning and maintenance operations. Blasters is a 
leading U.S. manufacturer of truck-mounted waterblasting equipment. Mark Rite Lines Equipment Company, Inc. (“MRL”), is 
a U.S. manufacturer of truck-mounted and ride-on road-marking and line-removal equipment. Trackless is a leading Canadian 
manufacturer of off-road, multi-purpose tractors and attachments. Ground Force and TowHaul are leading manufacturers of 
specialty vehicles that support the extraction of metals. Truck Bodies & Equipment International (“TBEI”) manufactures and 
sells dump truck bodies and trailers under the Ox Bodies, Crysteel, J-Craft, Duraclass, Rugby, Travis, OSW, NTE and WTB 
brand names, as well as a range of interchangeable truck body systems and waste-hauling products under the Bucks and Switch-
N-Go brand names.

Safety and Security Systems Group

The Company’s Safety and Security Systems Group is a leading manufacturer and supplier of comprehensive systems and 
products that law enforcement, fire rescue, emergency medical services, campuses, military facilities and industrial sites use to 
protect people and property. Offerings include systems for community alerting, emergency vehicles, first responder 
interoperable communications and industrial communications. Specific products include public safety equipment, such as 
vehicle lightbars and sirens, industrial signaling equipment, public warning systems and general alarm/public address systems. 
Products are sold under the Federal SignalTM, Federal Signal VAMA®, and Victor® brand names. The Group operates 
manufacturing facilities in the U.S., Spain, the United Kingdom (“U.K.”), and South Africa.

Marketing and Distribution

Depending primarily on the type and geographic location of the end-customer, the Environmental Solutions Group uses either a 
dealer network or direct sales to serve customers. The dealer network serves both municipal and industrial end-markets. Within 
municipal markets, the majority of the Company’s dealers operate exclusively in their assigned territory. In conjunction with 
selling vehicles to end-customers, dealer representatives demonstrate vehicle functionality and capability and provide vehicle 
service. In addition to selling products manufactured by the Company, certain of our businesses distribute and re-sell products 
manufactured by other companies. The Company believes its regional, national and global dealer networks for vehicles is a 
distinguishing factor from its competitors. The Company has an ownership interest in certain dealers.  

The Environmental Solutions Group’s direct sales channel concentrates primarily on the industrial, utility and construction 
market segments. To support current and potential customers in these market segments, the Group also engages in the sale of 
parts, service and repair, equipment rentals and training through its service centers located across North America.

The Safety and Security Systems Group sells to industrial customers through wholesalers and distributors who are supported by 
Company sales personnel or independent manufacturer representatives. Products are also sold to municipal and governmental 
customers through active independent distributors, as well as through original equipment manufacturers and the direct sales 
force. The Company sells comprehensive integrated warning and interoperable communications through a combination of the 
direct sales force and independent distributors. International sales are made through independent foreign distributors or on a 
direct basis. 

Customers and Backlog

No single customer accounted for 10% or more of the Company’s net sales in any year within the three-year period ended 
December 31, 2023. 

The Company’s backlog totaled $1.03 billion at December 31, 2023, compared to $879 million at December 31, 2022. 
Backlogs vary by group due to the nature of the Company’s products and the buying patterns of its customers. The 
Environmental Solutions Group typically experiences an average backlog of approximately three to six months of shipments. 
The Safety and Security Systems Group typically experiences an average backlog of approximately two months of shipments. 
While supply chain disruption and customer demand have contributed to longer lead times for certain businesses, production of 
the Company’s December 31, 2023 backlog is expected to be substantially completed during 2024.

Suppliers

The Company purchases a wide variety of raw materials from around the world for use in the manufacture of its products, 
although the majority of its purchases are currently from North American sources. To minimize risks relating to availability, 
price and quality of key products and components, the Company is party to numerous strategic supplier arrangements. Although 
certain materials are obtained from either a single-source supplier or a limited number of suppliers, the Company has generally 
identified alternative sources to minimize the interruption of its business in the event of supply disruptions. However, a 
transition to a new supplier may cause the Company to incur supply disruptions and unanticipated costs. 

Components critical to the production of the Company’s vehicles, such as engines, are purchased from a select number of 
suppliers. The Company also purchases raw and fabricated steel, as well as commercial chassis, from multiple sources. In 
addition, we may incorporate chassis provided directly by our customers in our production process. In those situations, the 
Company’s production processes rely upon the customer providing the chassis on a timely basis. Certain of the Company’s 
businesses also rely on the availability of inventory supplied by others to meet customer demand. 

The Company actively manages material supply sourcing and employs various methods to limit risk associated with commodity 
cost fluctuations and availability. Throughout 2023, supply chain conditions continued to gradually improve. However, the 

3

Company continues to experience sporadic supply shortages and extended lead times for some components and raw materials, 
including certain classes of chassis and electronic components that are important to its manufacturing processes. The Company 
has designed and implemented plans to partially mitigate the impact of these challenges by using alternate suppliers, re-
engineering products, expanding its supply base globally, leveraging overall purchasing volumes to obtain favorable pricing 
and quantities and developing a closer working relationship with key suppliers. However, the Company can provide no 
assurance that those efforts will be successful. Although global supply chain conditions have improved in 2023, component 
shortages may persist into 2024, which could limit the Company’s ability to maximize production. 

Competition

Within the Environmental Solutions Group, Elgin is recognized as a market leader among domestic sweeper competitors and 
differentiates itself primarily on product performance. The Vactor, TRUVAC and Guzzler brands each maintain a leading 
domestic position in their respective marketplaces by enhancing product performance with leading technology and application 
flexibility. Jetstream is a market leader in the in-plant cleaning segment of the U.S. waterblast industry, competing on product 
performance, rapid delivery and solutions services. Joe Johnson Equipment, Inc. with Joe Johnson Equipment (USA), Inc., 
(collectively, “JJE”), is a leading Canadian-based distributor of maintenance equipment for municipal and industrial markets. 
Blasters is a leading U.S. manufacturer of truck-mounted waterblasting equipment. MRL is a U.S. manufacturer of truck-
mounted and ride-on road-marking and line-removal equipment. Trackless is a leading Canadian manufacturer of off-road, 
multi-purpose tractors and attachments. Ground Force and TowHaul are leading manufacturers of specialty vehicles that 
support the extraction of metals. TBEI includes a portfolio of regional dump truck body and trailer brands with market 
leadership positions in distinct geographies and product categories, differentiating itself with its broad regional distribution 
network, focus on customer responsiveness and operational expertise. 

Within specific product categories and domestic markets, the businesses within the Safety and Security Systems Group are 
among the market leaders. This Group’s international market position varies from leader to ancillary participant depending on 
the geographic region and product line. Generally, competition is intense within all of this Group’s product lines and purchase 
decisions are made based on price, features, reputation, performance and service, often within competitive bidding situations.

Patents and Trademarks

The Company owns a number of patents and possesses rights under others to which it attaches importance, but it does not 
believe that its business as a whole is materially dependent upon any such patents or rights. The Company also owns a number 
of trademarks, including those listed within the “Narrative Description of Business” section above. We believe these 
trademarks are important in connection with the identification of our products and associated goodwill with customers, but no 
material part of the Company’s business is dependent on our trademarks.

Human Capital Management

As of December 31, 2023, the Company employed approximately 4,500 people in its businesses located in five countries, with 
the Company’s U.S. hourly employees accounting for approximately 54% of its total workforce. As of December 31, 2023, 
approximately 9% of the Company’s U.S. hourly workers were represented by unions.

The Company believes that its employees are key to its ability to deliver exceptional products and services to its customers. The 
Company applies a holistic total rewards strategy, designed to recruit, motivate, and retain talented employees at all levels of 
the organization and offer competitive, market-based compensation programs and attractive benefit packages.

Human Rights

The Company is committed to respecting and upholding the internationally recognized human rights principles of the United 
Nations’ Guiding Principles on Business and Human Rights and the Universal Declaration of Human Rights. In every state and 
country where the Company operates, it upholds standards that meet or exceed those established by local, state, and national 
legal frameworks, and the Company expects its partners, suppliers, vendors, and contractors to do the same. The Company has 
published a human rights policy, setting forth its commitment to equality and nondiscrimination, elimination of all forms of 
forced or compulsory labor, the effective abolition of childhood labor, workers’ rights to freedom of association and 
unionization, and protecting employees’ ability to confidentially report policy violations.

Cultural Philosophy

The Company is committed to promoting and supporting an inclusive culture throughout the organization, and believes that 
hearing different voices, and seeking different perspectives and ideas, leads to better results. The Company is proud of the 
diversity on its Board of Directors, senior management and in leadership roles throughout the Company. Currently, two of the 

4

Company’s eight directors self-identify as members of a minority group. 

In addition, three of the Company’s directors are female, placing the Company ahead of the 29% average for companies in the 
Russell 3000 Index. Of the companies in the Russell 3000 Index, approximately 7% have a female Chief Executive Officer 
(“CEO”), and the Company is proud to be among that group. In addition, 50% of the Company’s current executive officers are 
female, including the Company’s President and CEO, Vice President and General Counsel, and Vice President, Chief 
Accounting Officer and Controller.

The Company’s cultural philosophy is further evidenced by its policies related to various aspects of employment, including, but 
not limited to, recruiting, selecting, hiring, employment placement, job assignment, compensation, access to benefits, selection 
for training, use of facilities, and participation in Company-sponsored employee activities. In recent years, the Company’s 
Executive Leadership Team, comprised of business leaders from across the organization, completed a comprehensive 
educational awareness training led by an industry expert and completed supplemental training on the importance of building 
inclusive workplaces. Additionally, the Company piloted training at a key manufacturing location in 2022 and provided 
facilitated training at another key manufacturing location in 2023.

Employee Recruitment, Training and Development

The Company believes that identifying and developing the next generation of business leaders is important to its long-term 
success, and is proud to support its employees in furthering their education with tuition reimbursement programs and training. 

The Company’s recruitment program follows a defined process to attract and hire top talent, including a college internship 
program designed to identify and cultivate an early-in-career pipeline of talent, and employee referral bonus programs. The 
Company additionally engages external professional recruiting firms to supplement its internal recruiting efforts, as needed.

The Company provides extensive training to employees within its facilities, ranging from topics such as workplace safety, anti-
fraud, anti-discrimination and anti-harassment training, to advanced instruction in lean manufacturing principles and inside 
sales training programs. On average, the Company’s employees each receive more than 10 hours of job training per year, with 
some employees of certain business units each averaging nearly 80 hours of training per year. 

Through its Tuition Assistance Program, the Company also aims to assist and encourage employees to expand their knowledge, 
skills, and job effectiveness by continuing their education at local accredited institutions of higher learning. Certain of the 
Company’s businesses also partner with nearby universities, from time to time, to offer courses and programs directly related to 
the employee’s growth in the business.

The Company maintains a robust annual performance management process across the organization. Employees start the process 
by working with their supervisors to set individual performance goals. Progress against those objectives is tracked throughout 
the year, culminating in the year-end performance review process, which involves the completion of an employee self-
assessment and a discussion between the employee and their supervisor on goal accomplishment and defined core 
competencies. In addition, the Company’s annual talent and succession management processes are designed to identify and 
develop next-level successors through a variety of assignments and experiential learning. 

The Company actively seeks opportunities for regular engagement and communication with its CEO and other senior executive 
leaders with its broader employee population. In addition, many of the Company’s businesses perform employee engagement 
surveys that provide valuable feedback to the management teams.

The Company is committed to the communities in which it operates, and to developing a strong pipeline from which it can 
recruit new talent. Many of the Company’s businesses support their local high schools with cooperative learning extension 
programs at their manufacturing plants, hosting in-person or virtual tours of our facilities, and providing scholarships and 
“signing-day” offers to high school seniors. The Company’s employees raise funds and donate time to a variety of community 
engagement initiatives and support expanded outreach to diverse communities.

The Company’s employees also donate time and expertise through volunteering and mentorship programs, and work with local 
colleges on training programs to teach valuable technical skills that can be applied in the workplace. Many of the Company’s 
businesses also recruit summer interns from regional universities, providing hands-on experience in a manufacturing setting and 
building a pipeline for future engineers, information technology (“IT”) specialists and financial analysts. These programs 
attempt to help the Company’s next generation, and others, understand what career paths may be available to them and to 
explore future job opportunities with the Company. 

Safety

The Company considers the safety of its employees a significant focus and strives to have zero workplace injuries. The 
Company has established an enterprise-wide Safety Council, which includes representatives from several of our manufacturing 
facilities. The Safety Council meets regularly to collaborate and implement safety improvement measures, including workplace 
hazard reduction programs and awards focusing on continuous improvement initiatives and the reduction of incident frequency.   

5

Governmental Regulation of the Environment

The Company endeavors to establish environmentally-friendly policies and objectives, and believes that these actions are also 
consistent with cost-effective operating practices. With the application of these policies, the Company believes it complies with 
federal, state and local provisions that have been enacted or adopted regulating the discharge of materials into the environment, 
or otherwise relating to the protection of the environment. Capital expenditures in 2023 attributable to compliance with such 
laws were not material. The Company also believes that the overall impact of compliance with environmental regulations will 
not have a material adverse effect on our financial position, results of operations or cash flow.

Seasonality

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.

Executive Officers of the Registrant

The following is a list of the Company’s executive officers, including their ages, business experience and positions as of 
February 1, 2024:

Item 1A.    Risk Factors.

We may occasionally make forward-looking statements and estimates such as forecasts and projections of our future 
performance or statements of our plans and objectives. These forward-looking statements may be contained in, but are not 
limited to, filings with the SEC, including this Form 10-K, press releases made by us and oral statements made by our officers. 
Actual results could differ materially from those contained in such forward-looking statements. Important factors that could 
cause our actual results to differ from those contained in such forward-looking statements include, but are not limited to, the 
risks described below. 

Macroeconomic and Industry Risks

Our financial results are subject to U.S. economic uncertainty and compliance with laws and regulations.

In 2023, we generated approximately 78% of our net sales in the U.S. Our ability to be profitable depends heavily on varying 
conditions in the U.S. governmental and municipal markets, as well as the overall U.S. economy. The industrial markets in 
which we compete are subject to considerable cyclicality, and move in response to cycles in the overall business environment. 
Many of our customers are municipal government agencies, and as a result, we are dependent on municipal government 
spending. Spending by our municipal customers can be affected by federal, state and local political circumstances, budgetary 
constraints, changing priorities, actual or potential government shutdowns and other factors. The U.S. government and 
municipalities depend heavily on tax revenues as a source of spending and accordingly, there is a historical correlation that 
suggests a lag of one to two years between the condition of the U.S. economy and our sales to the U.S. government and 
municipalities. Therefore, downturns in the U.S. economy are likely to result in decreases in demand for our products. During 
previous economic downturns, we experienced decreases in sales and profitability, and we expect our business to remain 
subject to similar economic fluctuations in the future. In addition, the extent of any potential changes to policies, tax laws and 
regulations and how any such changes may impact the Company’s financial results and operations, is currently uncertain. For 
example, the Organization for Economic Co-operation and Development has issued Pillar Two model rules introducing a new 
global minimum corporate tax of 15% intended to be effective on January 1, 2024. While the U.S. has not yet adopted the Pillar 
Two rules, various non-U.S. governments are enacting legislation. As currently designed, Pillar Two would apply to our 
worldwide operations. We currently do not expect these rules to materially increase our global tax costs because we do not have 
material operations in jurisdictions with tax rates lower than the Pillar Two minimum. We continue to monitor U.S. and global 
legislative action related to Pillar Two for potential impacts.

Government administrations and agencies, political figures, the investment community, employees and other stakeholders have 
had an increased focus on sustainability issues and initiatives. Regulatory and other legal changes in laws in response to such 
matters could require material efforts and costs by us, and our suppliers, to comply with such changes. The costs of compliance 
with the various laws, regulations and policies applicable to us could be significant and penalties for non-compliance could 
significantly impact our business.    

We have international operations that are subject to compliance with domestic and foreign laws and regulations, economic and 
political uncertainties and conflicts and foreign currency rate fluctuations.

Our business is subject to fluctuations in demand and changing international economic, legal and political conditions that are 
beyond our control. In 2023, approximately 22% of our net sales were to customers outside the U.S. and we expect a significant 
portion of our revenues to come from international sales in the foreseeable future. Operating in the international marketplace 
exposes us to a number of risks, including the need to comply with U.S. and foreign laws and regulations applicable to our 
foreign operations, such as the Foreign Corrupt Practices Act, the United Kingdom (“U.K.”) Bribery Act and their counterparts 
in other foreign jurisdictions in which we operate, restrictive domestic and international trade regulations, and changes in these 
laws, regulations and policies by the U.S. and foreign governments. In addition, we may be exposed to risks and adverse 
economic effects associated with changes in tax laws, geopolitical conflicts, actual or threatened imposition of tariffs or trade 
barriers on our products or materials incorporated into our products, actual or threatened trade disputes, including so-called 
“trade wars,” political and economic instability in the jurisdictions in which we operate, foreign receivables collection risk and 
local labor market conditions. 

To the extent that our international operations are affected by adverse foreign economic or political conditions, we may 
experience disruptions and losses that could have a material impact on our financial position, results of operations or cash flow. 
To mitigate the risk of foreign receivables collection, we may obtain letters of credit from international customers to satisfy 
concerns regarding the collectability of amounts billed to customers. 

Some of our contracts are denominated in foreign currencies, which may expose us to risks of fluctuating currency values and 
exchange rates, hard currency shortages and controls on currency exchange. Changes in the value of foreign currencies over the 
long term could increase our U.S. dollar costs for, or reduce our U.S. dollar revenues from, our foreign operations. Any 
increased costs or reduced revenues as a result of foreign currency fluctuations could adversely affect our results of operations.

7

Inflation in the United States and elsewhere could adversely affect our business.

We are exposed to inflation effects, which could negatively affect our business, financial condition and results of operation. The 
United States and other jurisdictions have experienced high levels of inflation in recent years. If the inflation rate increases, it 
will likely affect our expenses, including, but not limited to, employee compensation and labor expenses and increased costs for 
supplies, and we may not be successful in offsetting such cost increases through pricing actions.

The execution of our growth strategy is dependent upon the continued availability of credit and third-party financing 
arrangements for our customers.

Economic downturns result in tighter credit markets, which could adversely affect our customers’ ability to secure financing or 
to secure financing at favorable terms or interest rates necessary to proceed or continue with purchases of our products and 
services. Further, certain government agencies, including the U.S. Treasury, have previously implemented and may continue to 
implement policies that have resulted and may continue to result in significantly increased interest rates and borrowing costs. 
Our customers’ or potential customers’ inability to secure financing for projects could result in the delay, cancellation or 
downsizing of new purchases or the suspension of purchases already under contract, which could cause a decline in the demand 
for our products and services and negatively impact our financial position, results of operations or cash flow.

We operate in highly competitive markets.

The markets in which we operate are highly competitive. Many of our competitors have significantly greater financial resources 
than we do. The intensity of this competition, which is expected to continue, can result in price discounting and margin 
pressures throughout the industry and may adversely affect our ability to increase or maintain prices for our products. In 
addition, certain of our competitors may have lower overall labor or material costs. In some cases, our contracts with municipal 
and other governmental customers are awarded and renewed through competitive bidding. We may not be successful in 
obtaining or renewing these contracts, which could have an adverse effect on our financial condition, results of operations or 
cash flow.

Strategic and Operational Risks

The inability to obtain raw materials, component parts and/or finished goods in a timely and cost-effective manner would 
adversely affect our ability to manufacture and market our products.

We purchase from suppliers raw materials, component parts and finished goods to be used in the manufacturing and sale of our 
products. In addition, we may incorporate vehicle chassis provided directly by our customers in our production process. 
Although the vast majority of our raw materials and component parts are sourced domestically, certain of our suppliers are 
based overseas, and certain of our domestic suppliers may source subcomponents from overseas. Global markets for various 
products and goods have suffered, and are continuing to suffer, material disruptions to certain supply chains, in part due to the 
coronavirus pandemic and geopolitical conflicts, including the war between Russia and Ukraine and the war between Israel and 
Hamas. Changes in our relationships with suppliers, shortages in availability of materials, production delays, regulatory 
restrictions, public health crises, labor stoppages or other supply chain disruptions, whether due to our suppliers or customers, 
could have a material adverse effect on our ability to timely manufacture and deliver products to our customers. In addition, our 
profit margins would decrease if prices of purchased raw materials, component parts or finished goods increase and we are 
unable to pass on those increases to our customers. 

Challenges within global logistics networks, including trucking and chassis shortages and shortages in labor availability, have 
also contributed to delays in receiving key manufacturing components, increased order backlogs and higher transportation 
costs. Such logistical disruption may cause us to incur higher freight costs to expedite the receipt of components from our 
suppliers or the delivery of products to our customers, and may also result in longer lead times for our customers.

As economies around the world recovered following the most significant effects of the pandemic, sharp increases in demand 
created significant disruption to the global supply chain, which adversely affected our ability to receive goods on a timely basis 
and increased our material costs. Throughout 2023, supply chain conditions have continued to gradually improve. However, we 
continue to experience supply shortages and extended lead times for some components and raw materials, including certain 
classes of chassis and electronic components that are important to our manufacturing processes. When facing supply-related 
challenges, we may increase our inventory levels and purchase commitments to shorten lead times and to help maintain 
adequate inventory levels to meet customer expectations. While we actively monitor and take steps in an effort to mitigate 
supply chain risk, there can be no assurance that our ongoing mitigation plans will prevent disruptions that may arise from 
shortages of materials that we use in the production of our products. 

Global supply chain disruptions may continue to adversely affect our business and our outlook.  If we are unable to recover a 
substantial portion of the increase in material and transportation costs from our customers through price adjustments and/or 

8

surcharges, our business or results of operations could be adversely affected. We may also experience an increase in order 
cancellations if any such pricing actions are not accepted by our customers.       

Failure to keep pace with technological developments may adversely affect our operations.

We are engaged in an industry that will be affected by future technological developments. The introduction of products or 
processes utilizing new technologies, including those resulting from any new environmental, safety and other regulations, 
artificial intelligence and machine learning, could require us and our suppliers to make significant changes to existing products 
or processes in order for them to remain marketable and competitive. Our success will depend upon our ability to source, 
develop and introduce on a timely and cost-effective basis new products, applications and processes that keep pace with 
technological developments, applicable regulations and address increasingly sophisticated customer requirements. We may not 
be successful in identifying, sourcing, developing and marketing new products, applications and processes and product or 
process enhancements. Further, if we implement emerging technologies such as artificial intelligence and machine learning into 
our products and services, we may not be able to anticipate vulnerabilities, flaws or security threats resulting from the use of 
such technology and develop adequate protection measures. We may experience difficulties that could delay or prevent the 
successful development, introduction and marketing of product or process enhancements or new products, applications or 
processes. Our products, applications or processes may not adequately meet the requirements of the marketplace and achieve 
market acceptance. Our financial condition, results of operations or cash flow could be materially and adversely affected if we 
or our suppliers were to incur delays in developing new products, applications or processes or product or process enhancements, 
or if our products do not gain market acceptance.

Our efforts to develop new products and services or enhance existing products and services involve substantial research, 
development and marketing expenses, and the resulting new or enhanced products or services may not generate sufficient 
revenues to justify the expense.

We place a high priority on developing new products and services, as well as enhancing our existing products and services. As 
a result of these efforts, we may be required to expend substantial research, development and marketing resources, and the time 
and expense required to develop a new product or service or enhance an existing product or service are difficult to predict. We 
may not succeed in developing, introducing or marketing new products or services or product or service enhancements. In 
addition, we cannot be certain that any new or enhanced product or service will generate sufficient revenue to justify the 
expense and resources devoted to the related product diversification effort.

Disruptions within our dealer network or the inability of our dealers to secure adequate access to capital could adversely affect 
our business.

We rely on national and global dealer networks to market certain of our products and services. As a result, our business with 
respect to these products and services is influenced by our ability to manage new and existing relationships with dealers. While 
we have relatively low turnover of dealers, from time to time, we or a dealer may choose to terminate the relationship as a result 
of difficulties that our dealers experience in operating their businesses due to economic conditions or other factors. While we do 
not believe our business is dependent on any single dealer, a disruption in our dealer network, or with a significant dealer, or 
within a specific market, could have an adverse impact on our business within the affected market. In addition, our dealers 
require adequate liquidity to finance their operations, including purchases of our products. Dealers are subject to numerous risks 
and uncertainties that could unfavorably affect their liquidity positions, including, among other things, continued access to 
adequate financing sources on a timely basis on reasonable terms. These sources of financing are vital to our ability to sell 
products through our dealer network. Recent significant increases in interest rates and any future deterioration in the liquidity or 
credit worthiness of our dealers could have a significant adverse effect on our business. From time to time, we may provide 
financing assistance to dealers or consider taking ownership positions. The loss or termination of a significant dealer, or a 
significant number of dealers, could cause difficulties in marketing and distributing our products and have an adverse effect on 
our business, financial condition, results of operations or cash flow. 

We may be unsuccessful in our future acquisitions, if any, which may have an adverse effect on our business.

Our long-term strategy includes exploring acquisitions of companies or businesses to facilitate our growth, enhance our global 
market position and broaden our product offerings. Such acquisitions may help us expand into adjacent markets, add 
complementary products and services or allow us to leverage our distribution channels. In connection with this strategy, we 
could face certain risks and uncertainties in addition to those we face in the day-to-day operations of our business. We also may 
be unable to identify suitable targets for acquisition or to make acquisitions at favorable prices. If we identify a suitable 
acquisition candidate, our ability to successfully implement the acquisition would depend on a variety of factors, including our 
ability to obtain financing on acceptable terms, especially with interest rates at comparatively high levels. In addition, our 

9

acquisition activities could be disrupted by overtures from competitors for the targeted companies, governmental regulation and 
rapid developments in our industry that decrease the value of a potential target’s products or services.

Acquisitions involve risks, including those associated with the following:

integrating the operations, financial reporting, disparate systems and processes and personnel of acquired companies;

•
• managing geographically dispersed operations;
•
•
•
•

diverting management’s attention from other business concerns;
changing the competitive landscape, including disrupting existing sales channels or markets;
entering markets or lines of business in which we have either limited or no direct experience; and
losing key employees, customers and strategic partners of acquired companies.

We also may not achieve anticipated revenue and cost benefits associated with our acquisitions. Acquisitions may not be 
accretive to our earnings and may negatively impact our results of operations as a result of, among other things, the incurrence 
of debt, acquisition costs, impairment of goodwill and amortization of other intangible assets. In addition, future acquisitions 
could result in dilutive issuances of equity securities.

Businesses acquired by us may have liabilities that are not known to us.

We may assume liabilities in connection with the acquisition of businesses. There may be liabilities that we fail or are unable to 
discover in the course of performing due diligence investigations on the acquired businesses, or that may be more material than 
we expected. In these circumstances, we cannot assure that our rights to indemnification will be sufficient in amount, scope or 
duration to fully offset the possible liabilities associated with the businesses or property acquired. Further, these liabilities could 
result in unexpected legal or regulatory exposure, unexpected increases in taxes or other adverse effects on our business. Any 
such liabilities, individually or in the aggregate, could have a material adverse effect on our financial condition, results of 
operations or cash flow.

We could incur restructuring and impairment charges as we continue to evaluate opportunities to restructure our business and 
rationalize our manufacturing operations in an effort to optimize our cost structure.

We continue to evaluate opportunities to restructure our business and rationalize our manufacturing operations in an effort to 
optimize our cost structure. These actions could result in significant charges that could adversely affect our financial condition 
and results of operations. Future actions could result in restructuring and related charges, including but not limited to 
impairments, employee termination costs and charges for pension and other postretirement contractual benefits and pension 
curtailments that could be significant and could have an adverse effect on our financial condition, results of operations or cash 
flow.

Indebtedness Risk

We are subject to a number of restrictive debt covenants.

Our credit facility contains certain restrictive debt covenants and customary events of default. Our ability to comply with these 
restrictive covenants may be affected by the other factors described in this “Risk Factors” section, as well as other factors 
outside of our control. Failure to comply with one or more of these restrictive covenants may result in an event of default 
which, if not cured by us or waived by our lenders, allows our lenders to declare all amounts outstanding as due and payable. 
Such an acceleration of the maturity of our indebtedness may cause us to incur substantial costs and may prevent or limit us 
from engaging in transactions that benefit us, including responding to changing business and economic conditions and taking 
advantage of attractive business opportunities. 

Human Capital and Labor Risks

Our ability to operate effectively could be impaired if we fail to attract and retain key personnel.

Our ability to operate our businesses and implement our strategies depends in part on the efforts of our executive officers and 
other key employees. In addition, our future success will depend on, among other factors, our ability to attract and retain 
qualified personnel. The loss of the services of any key employee or the failure to attract or retain other qualified personnel 
could have a material adverse effect on our business or business prospects.

10

Additionally, availability of labor in the markets in which we operate has declined in recent years and competition for such 
labor has increased. A significant increase in wages paid by competitors for employees similar to our work force could result in 
insufficient availability of workers and/or increase our labor costs. In the event prevailing wage rates continue to increase in the 
markets in which we operate, we may be required to concurrently increase the wages paid to our employees to maintain the 
quality of our work force and customer service. If the supply of skilled labor is constrained or our costs of attracting and 
maintaining a workforce increase, our profit margins could decrease as well as our ability to maximize production and meet 
customer demand.

Our business may be adversely impacted by work stoppages and other labor relations matters.

As a portion of our workforce is unionized, we are subject to risk of work stoppages and other labor relations matters. As of 
December 31, 2023, approximately 9% of our U.S. hourly workers were represented by labor unions and were covered by 
collective bargaining agreements with various unions. Any strikes, threats of strikes or other organized disruptions in 
connection with the negotiation of new labor agreements or other negotiations could materially adversely affect our business as 
well as impair our ability to implement further measures to reduce costs and improve production efficiencies. In addition, the 
stoppage of work for a prolonged period of time at one, or several, of our principal manufacturing facilities, due to public health 
concerns, or any other reason, could materially adversely affect our business.

Our pension funding requirements and expenses are affected by certain factors outside of our control, including the 
performance of plan assets, the discount rate used to value liabilities, actuarial assumptions and experience and legal and 
regulatory changes.

Our funding obligations and pension expense for our defined benefit pension plans are driven by the performance of assets set 
aside in trusts for these plans, the discount rate used to value the plans’ liabilities, actuarial assumptions and experience and 
legal and regulatory funding requirements. Changes in these factors could have an adverse impact on our financial condition, 
results of operations or cash flow. In addition, a portion of our pension plan assets are invested in equity securities, which can 
experience significant declines if financial markets weaken. The level of the funding of our defined benefit pension plan 
liabilities was approximately 88% as of December 31, 2023. Funding of the Company’s U.S. defined benefit pension plan is 
determined in accordance with guidelines set forth in the Employee Retirement Income Security Act. Our future pension 
expenses and funding requirements could increase significantly due to the effect of adverse changes in the discount rate, asset 
values or the estimated expected return on plan assets. In addition, we could become legally required to make increased cash 
contributions to the pension plans, and these contributions could be material and negatively affect our cash flow.

Data Security and Intellectual Property Risks

Increased IT security threats, including more sophisticated cybersecurity attacks, pose a risk to our systems, networks, products 
and operations.

We rely upon IT systems and networks, some of which are managed by third parties, to support a variety of business processes 
and activities, and to comply with regulatory, legal and tax requirements. Additionally, in the ordinary course of business, we 
collect and store sensitive information relating to our businesses, customers, suppliers and employees. Sensitive information 
may also be stored by our vendors and on the platforms and networks of third-party providers. The secure operation of these IT 
systems and networks and processing and maintenance of this information is critical to the Company’s business operations and 
strategy. 

These IT systems and networks may be susceptible to damage, disruptions or shutdowns due to hardware failures, computer 
viruses, cybersecurity attacks, telecommunication failures, user errors, catastrophic events or other factors. Further, IT security 
threats are growing in frequency and sophistication. Accordingly, we have implemented and continue to implement measures to 
address cybersecurity incidents and mitigate potential risks to our systems from these IT-related disruptions. Despite the 
information security measures we have taken, our systems and networks remain potentially vulnerable to cybersecurity 
incidents, as do those of our vendors and third-party providers. Cybersecurity incidents with respect to the Company, our 
vendors or our third-party providers could potentially result in the compromising of confidential information, misuse of our 
systems and networks, manipulation and destruction of data, misappropriation of assets or production stoppages and supply 
shortages, which in turn could adversely affect our reputation, financial condition, results of operations or cash flow. 

Although we have not suffered any significant cybersecurity incidents that have had a material business impact, we and our 
vendors have been the target of malicious cybersecurity threats and attacks. While various procedures and controls have been 
and are being utilized to mitigate IT risks, there can be no guarantee that the actions and controls that we and our third-party 
providers have implemented will be sufficient to protect our systems, information or other property.   

11

Infringement of, or an inability to protect, our intellectual property rights could adversely affect our business.

We rely on a combination of patents, trademarks, copyrights, nondisclosure agreements, IT security systems, physical security 
and other measures to protect our proprietary intellectual property and the intellectual property of certain customers and 
suppliers. However, we cannot be certain that our efforts to protect these intellectual property rights will be sufficient. 
Intellectual property protection is subject to applicable laws in various jurisdictions where interpretations and protections differ 
or can be unpredictable and costly to enforce. Further, our ability to protect our intellectual property rights may be limited in 
certain foreign jurisdictions that do not have, or do not enforce, strong intellectual property rights. Any failure to protect or 
enforce our intellectual property rights could have a material adverse effect on our competitive position, financial condition, 
results of operations or cash flow.

Legal and Financial Risks

We may incur material losses and costs as a result of lawsuits or claims that may be brought against us which are related to 
product liability, warranty, product recalls, intellectual property, client service interruptions or other matters.

We are exposed to product liability and warranty claims in the normal course of business in the event that our products actually 
or allegedly fail to perform as expected, or the use of our products results, or is alleged to result, in bodily injury and/or 
property damage. For example, we have been sued by firefighters seeking damages claiming that exposure to our sirens has 
impaired their hearing and that the sirens are, therefore, defective. In addition, we are subject to other claims and litigation from 
time to time, as further described in the accompanying notes to our consolidated financial statements. We could experience 
material product liability or warranty costs in the future and incur significant costs to defend ourselves against these claims. 
While we carry insurance and maintain reserves for product liability claims, our insurance coverage may be inadequate if such 
claims do arise, and any defense costs and liability not covered by insurance could have a material adverse impact on our 
financial condition, results of operations or cash flow. A future claim could involve the imposition of punitive damages, the 
award of which, pursuant to state laws, may not be covered by insurance. In addition, warranty and certain other claims are not 
typically covered by insurance. Any product liability or warranty issues may adversely impact our reputation as a manufacturer 
of high-quality, safe products and may have a material adverse effect on our business.

The costs associated with complying with environmental, safety and other regulations could lower our margins.

We, like other manufacturers, continue to face heavy governmental regulation of our products, especially in the areas of the 
environment and employee health and safety. Increased public awareness and concern regarding climate change and other 
related matters at numerous levels of government in various jurisdictions may lead to additional international, national, regional 
and local legislative and regulatory responses, and compliance with any new rules could be difficult and costly. These 
regulations could include environmental requirements applicable to manufacturing and vehicle emissions and regulations 
impacting our supply chain both nationally and internationally. Complying with environmental, safety and other regulations has 
added and will continue to add to the cost of our products, could increase the capital required to support our business and could 
affect the products and services that we offer. While we believe that we are in compliance in all material respects with these 
laws and regulations, we may be adversely impacted by costs, liabilities or claims with respect to our operations under existing 
laws or those that may be adopted. These requirements are complex, change frequently and have tended to become more 
stringent over time. Therefore, we could incur substantial costs, including cleanup costs, fines and civil or criminal sanctions as 
a result of violation of, or liabilities under, environmental laws and safety regulations. Further, climate change regulations at the 
federal, state or local level or in international jurisdictions could require us to limit emissions, change our manufacturing 
processes or product offerings, or undertake other activities which may require us to incur additional expense. These 
requirements may increase the cost of our products, which may diminish demand for those products. Additionally, uneven 
application of environmental, safety and other regulations could place our products at a cost or features disadvantage, which 
could reduce our revenues and profitability. 

An impairment in the carrying value of goodwill, intangible assets or long-lived assets could negatively affect our financial 
position and results of operations.

As of December 31, 2023, goodwill and intangible assets represented 29% and 13% of total consolidated assets, respectively. 
Rental equipment and properties and equipment are long-lived assets, which also collectively represented 20% of our total 
consolidated assets as of December 31, 2023. Goodwill and indefinite-lived intangible assets are tested for impairment 
annually, or more frequently if indicators of impairment exist. Definite-lived intangible assets and long-lived assets are 
reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be 
recoverable. In evaluating the potential for impairment of goodwill, intangible assets and long-lived assets, we make 
assumptions regarding future operating performance, business trends, competition and market and general economic conditions. 
Such analyses further require us to make certain assumptions about our sales, operating margins, growth rates and discount 
rates. There are inherent uncertainties related to these factors. An impairment charge may result from, among other things, a 

12

significant decline in operating results, adverse market conditions, unfavorable changes in applicable laws or regulations, or a 
variety of other factors. Our total consolidated assets and results of operations for the applicable period could be materially 
adversely affected if any such charge is recorded.

Item 1B.    Unresolved Staff Comments.

None.

Item 1C.    Cybersecurity

The Company does not believe that there are currently any known risks from cybersecurity threats that have materially affected 
or are reasonably likely to materially affect the Company’s business strategy, results of operations, or financial condition. 
However, the Company could face risks from cybersecurity threats in the future that could have a material adverse effect on its 
business strategy, results of operations, or financial condition. For more information on the Company’s cybersecurity-related 
risks, see Item 1A, Risk Factors of this Form 10-K.

Risk Management and Strategy

The Company’s processes for identifying, assessing, and managing material cybersecurity risks are incorporated into its overall 
Enterprise Risk Management process. The Company maintains a comprehensive cybersecurity risk management program, 
overseen by the Chief Information Officer (“CIO”) and Chief Information Security Officer (“CISO”), to support the security, 
confidentiality, integrity and availability of its critical information technology (“IT”) systems and information.

The Company conducts internal risk assessments, with the assistance of independent third parties, against standards including 
the National Institute of Standards and Technology Cybersecurity Framework. The assessment results are used to develop 
responsive cybersecurity controls and risk mitigation strategies. The Company’s cybersecurity risk management program 
provides the structure for managing the respective risks through the use of a combination of automated tools, technologies and 
third-party monitoring, as well as ongoing employee education via cybersecurity training and security awareness 
communications. 

The Company’s cybersecurity risk management program includes an incident response plan, which provides a documented 
framework to support the timely and effective resolution of actual or attempted cybersecurity incidents. Cybersecurity incidents 
across the Company, and relevant third-party service providers, are tracked and significant incidents, as applicable, are 
promptly escalated to a cross-functional cybersecurity task force so that decisions regarding public disclosure can be made in a 
timely manner by management and the Board of Directors. 

The Company’s Internal Audit function performs audits to evaluate and report on compliance with cybersecurity policies and 
procedures, reviews internal control certifications from relevant third-party service providers, and tests IT system and network 
controls as part of its annual assessment of the effectiveness of the Company’s internal controls. Additionally, the Company 
engages third-party specialists to conduct periodic tests, incident simulations and assessments to verify and continuously 
enhance its cybersecurity risk management program. 

Governance

The Board of Directors has overall responsibility for the oversight of risk management, and has delegated oversight of 
cybersecurity risk management to the Audit Committee. The Company’s CIO and CISO regularly report to the Audit 
Committee on cybersecurity risks, updates on key initiatives and progress toward the Company’s objectives. In addition, the 
CIO provides updates to the Board of Directors, at least annually, on the Company’s broader IT strategy and key initiatives.

The CIO and CISO have primary responsibility over the Company’s cybersecurity risk management program. Quarterly 
updates are provided to the Company’s IT Council, comprised of executive, business unit and IT leaders from across the 
organization, regarding IT initiatives and risk management processes. 

Item 2.    Properties.

As of December 31, 2023, the Company utilized 17 principal manufacturing plants located throughout the U.S., as well as two 
in Europe, three in Canada and one in South Africa. The Company also leases facilities within the U.S., Europe and Canada 
from which we provide sales, service and/or equipment rentals. As of December 31, 2023, the Company devoted approximately

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is designed to provide 
information that is supplemental to, and shall be read together with, the consolidated financial statements and the accompanying 
notes contained in this Form 10-K. Information in MD&A is intended to assist the reader in obtaining an understanding of (i) 
the consolidated financial statements, (ii) the Company’s business segments and how the results of those segments impact the 
Company’s results of operations and financial condition as a whole and (iii) how certain accounting principles affect the 
Company’s consolidated financial statements.

Executive Summary

The Company is a leading global manufacturer and supplier of (i) vehicles and equipment for maintenance and infrastructure 
end-markets, including sewer cleaners, industrial vacuum loaders, safe-digging trucks, street sweepers, waterblasting 
equipment, road-marking and line-removal equipment, dump truck bodies, trailers, metal extraction support equipment and 
multi-purpose tractors, and (ii) public safety equipment, such as vehicle lightbars and sirens, industrial signaling equipment, 
public warning systems and general alarm/public address systems. In addition, we engage in the sale of parts, service and 
repair, equipment rentals and training as part of a comprehensive aftermarket offering to our customer base. We operate 23 
manufacturing facilities in five countries and provide products and integrated solutions to municipal, governmental, industrial 
and commercial customers in all regions of the world. 

As described in Note 17 – Segment Information to the accompanying consolidated financial statements, the Company’s 
business units are organized in two reportable segments: the Environmental Solutions Group and the Safety and Security 
Systems Group. 

Operating and Financial Performance in 2023

Conditions in our end markets remained strong throughout 2023, with demand for our products and services at unprecedented 
levels. We continued to execute against our organic growth initiatives, and with contributions from our recent value-added 
acquisitions and additional efficiency gains resulting from the application of our eighty-twenty initiatives, we were able to 
sustain a high level of financial performance. As the year progressed, we saw improvement in supply chain conditions, which 
facilitated increased production levels at several of our facilities and, despite some lingering supply chain-related operational 
inefficiencies, we were able to deliver record financial results for our stockholders, with double-digit year-over-year top line 
and earnings growth, margin expansion and significant improvement in cash flow generation. 

Included among the Company’s highlights in 2023 were the following: 

•

Orders for the year were at a record level of $1.87 billion, an increase of $178 million, or 11%, from last year.

Backlog at December 31, 2023 was $1.03 billion, another Company record, and an increase of $146 million, or 17%, 
compared to the end of last year. 

Net sales for the year ended December 31, 2023 were $1.72 billion, the highest level in our history, and an increase of 
$288 million, or 20% from last year. 

For the year ended December 31, 2023, we reported operating income of $224.5 million, an increase of $63.7 million, 
or 40%, from last year. 

Consolidated operating margin for the year ended December 31, 2023 was 13.0%, compared to 11.2% in the prior 
year. 

For the year ended December 31, 2023, we reported net income of $157.4 million, an increase of $37.0 million, or 
31%, from last year. 

On a consolidated basis, we reported adjusted EBITDA* of $286.0 million for the year ended December 31, 2023, an 
increase of $71.0 million, or 33%, from last year. 

Adjusted EBITDA margin* for the year ended December 31, 2023 was 16.6%, up from 15.0% last year.

Cash flow from continuing operating activities for the year ended December 31, 2023 was $194 million, an increase of 
$123 million, or 171%, from last year.

• With our strong balance sheet, positive operating cash flow, and increased capacity under our credit facility, we are 
well positioned to continue to invest in internal growth initiatives, pursue strategic acquisitions and consider ways to 
return value to stockholders, as we did during 2023:

17

◦

Our capital expenditures in 2023 were approximately $30 million, and included a number of strategic 
investments in new machinery and equipment aimed at gaining operating efficiencies and expanding capacity 
at certain production facilities. 

◦ We continue to invest in new product development and are encouraged that these efforts will provide 

additional opportunities to further diversify our customer base, penetrate new end-markets and/or gain access 
to new geographic regions. 

◦ We continued to execute on our disciplined M&A strategy with the acquisitions of Blasters and Trackless. 

We have now completed 11 acquisitions since 2016.

◦ We demonstrated our commitment to returning value to our stockholders by paying cash dividends of $23.8 

million, and spending $5.5 million to repurchase shares under our authorized repurchase program.

•

To highlight our ongoing focus on operating in a socially responsible and sustainable manner, we published our fourth 
annual Sustainability Report in June 2023.

*

The Company uses adjusted earnings before interest, tax, depreciation and amortization (“adjusted EBITDA”) and the ratio of adjusted EBITDA to net 
sales (“adjusted EBITDA margin”) as additional measures which are representative of its underlying performance and to improve the comparability of 
results across reporting periods. Refer to the Results of Operations section for further discussion regarding these non-GAAP metrics and a reconciliation 
of each to the most comparable GAAP measure for each of the periods presented.

(a) The Company uses adjusted EBITDA and adjusted EBITDA margin 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 are meaningful metrics to investors in evaluating the Company’s 
underlying financial performance. Adjusted EBITDA is a non-GAAP measure that represents the total of net income, interest expense, pension settlement 
charges, acquisition and integration-related expenses (benefits), coronavirus-related expenses, purchase accounting effects, other income/expense, income 
tax expense, and depreciation and amortization expense, where applicable. Adjusted EBITDA margin is a non-GAAP measure that represents the total of 
net income, interest expense, pension settlement charges, acquisition and integration-related expenses (benefits), coronavirus-related expenses, purchase 
accounting effects, other income/expense, income tax expense, and depreciation and amortization expense, where applicable, divided by net sales for the 
applicable period(s). Other companies may use different methods to calculate adjusted EBITDA and adjusted EBITDA margin. 

A discussion of changes in the Company’s financial condition and results of operations during the year ended December 31, 
2022 compared to the year ended December 31, 2021 has been omitted from this Form 10-K, but may be found under the 
heading “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s 
Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 1, 2023.

Year ended December 31, 2023 vs. year ended December 31, 2022

Net sales 

Net sales for the year ended December 31, 2023 increased by $287.9 million, or 20%, compared to the prior year, inclusive of 
the effects of acquisitions, pricing actions and increased chassis sales. The Environmental Solutions Group reported a net sales 
increase of $247.3 million, or 21%, primarily due to a $66.2 million improvement in aftermarket revenues and increases in sales 
of street sweepers, sewer cleaners, refuse trucks, multi-purpose tractors, metal extraction support equipment, industrial vacuum 
loaders, safe-digging trucks, trailers and road-marking and line-removal equipment of $38.6 million, $35.0 million, $31.1 
million, $21.4 million, $17.2 million, $16.3 million, $15.5 million, $10.5 million and $7.4 million, respectively. Partially 
offsetting these improvements was a reduction in sales of hoists and waterblasting equipment of $7.9 million and $5.1 million, 
respectively, as well as a $6.4 million unfavorable foreign currency translation impact. Within the Safety and Security Systems

Group, net sales increased by $40.6 million, or 17%, primarily due to improvements in sales of public safety equipment, 
industrial signaling equipment and warning systems of $22.7 million, $11.0 million and $6.8 million, respectively.

Cost of sales 

For the year ended December 31, 2023, cost of sales increased by $182.6 million, or 17%, compared to the prior year, largely 
due to an increase of $162.3 million, or 17%, within the Environmental Solutions Group, primarily related to increased sales 
volumes, inclusive of the effects of acquisitions, increased chassis costs and a $3.2 million increase in depreciation expense, 
partially offset by a $6.2 million favorable foreign currency translation impact. Within the Safety and Security Systems Group, 
cost of sales increased by $20.3 million, or 13%, primarily related to higher sales volumes, benefits from pricing actions and 
lower freight costs. 

Gross profit

For the year ended December 31, 2023, gross profit increased by $105.3 million, or 31%, compared to the prior year, primarily 
due to a $85.0 million improvement within the Environmental Solutions Group and a $20.3 million increase within the Safety 
and Security Systems Group. Gross profit as a percentage of net sales (“gross profit margin”) for the year ended December 31, 
2023 was 26.1%, compared to 24.0% in the prior year, primarily driven by improvements within the Environmental Solutions 
Group and Safety and Security Systems Group of 220 basis points and 180 basis points, respectively. 

Selling, engineering, general and administrative (“SEG&A”) expenses

For the year ended December 31, 2023, SEG&A expenses increased by $38.4 million, or 22%, compared to the prior year, 
primarily due to increases of $16.8 million, $6.3 million and $15.3 million within the Environmental Solutions Group, the 
Safety and Security Systems Group and Corporate, respectively. As a percentage of net sales, SEG&A expenses increased from 
12.0% in the prior year, to 12.2% in the current year.

Operating income 

Operating income for the year ended December 31, 2023 increased by $63.7 million, or 40%, compared to the prior year, 
largely due to the $105.3 million improvement in gross profit, partially offset by the $38.4 million increase in SEG&A 
expenses, a $2.3 million increase in amortization expense and a $0.9 million increase in acquisition-related costs. Consolidated 
operating margin for the year ended December 31, 2023 was 13.0%, compared to 11.2% in the prior year. 

Interest expense, net

Interest expense for the year ended December 31, 2023 increased by $9.4 million, or 91%, compared to the prior year, largely 
due to an increase in interest rates.

Other expense (income), net 

For the year ended December 31, 2023, Other expense (income), net, increased by $2.2 million compared to the prior year, 
primarily due to a $1.0 million increase in net periodic pension expense, a $0.8 million increase in estimated environmental 
remediation costs associated with a business discontinued in 2009, and a $0.4 million increase in foreign currency transaction 
losses.

Income tax expense

The Company recognized income tax expense of $45.6 million for the year ended December 31, 2023, compared to $30.5 
million for the year ended December 31, 2022. The increase in income tax expense in the current year was primarily due to 
higher earnings and the non-recurrence of certain discrete tax benefits recognized in the prior year associated with the release of 
valuation allowances, partially offset by a $1.5 million increase in the amount of excess tax benefits from stock compensation 
activity compared to the prior year. In the year ended December 31, 2022, the Company recognized a $2.6 million tax benefit 
from the release of a valuation allowance that had previously been recorded against deferred tax assets associated with foreign 
tax credits in the U.S., primarily due to tax planning. The Company also recognized a $1.1 million tax benefit during the year 
ended December 31, 2022 associated with the release of a valuation allowance in the U.K., as the associated deferred tax assets 
were considered more-likely-than-not to be realized primarily due to increased projections of future taxable income. Including 
these items, the Company’s effective tax rate for the year ended December 31, 2023 was 22.5%, compared to 20.2% in 2022. 
For further discussion, see Note 10 – Income Taxes to the accompanying consolidated financial statements.

20

Net income 

Net income for the year ended December 31, 2023 increased by $37.0 million, or 31%, compared to the prior year, largely due 
to the increased operating income, partially offset by increases in income tax expense, interest expense and other expense of 
$15.1 million, $9.4 million and $2.2 million, respectively.

Adjusted EBITDA

Adjusted EBITDA for the year ended December 31, 2023 was $286.0 million, compared to $215.0 million in the prior year. 
Adjusted EBITDA margin for the year ended December 31, 2023 was 16.6%, compared to 15.0% in the prior year.

(a) Coronavirus-related expenses relate to direct expenses incurred in connection with the Company's response to the coronavirus pandemic, that are 

incremental to, and separable from, normal operations. Such expenses primarily relate to incremental paid time off provided to employees and costs 
incurred to implement enhanced workplace safety protocols.   

(b) Purchase accounting effects represent the step-up in the valuation of equipment acquired in recent business combinations that was sold during the periods 

presented.

Total orders increased by $133.8 million, or 9%, for the year ended December 31, 2023, inclusive of the effects of acquisitions 
and pricing actions. U.S. orders increased by $73.1 million, or 6%, primarily due to improvements in orders for street sweepers, 
road-marking and line-removal equipment, dump truck bodies, multi-purpose tractors, industrial vacuum loaders and refuse 
trucks of $26.9 million, $22.9 million, $19.5 million, $12.0 million, $9.5 million and $6.4 million, respectively. Additionally, 
aftermarket demand increased by $43.2 million. Partially offsetting these improvements were reductions in orders for trailers,

safe-digging trucks and wasterblasting equipment of $36.9 million, $28.8 million and $7.4 million, respectively. Non-U.S. 
orders increased by $60.7 million, or 25%, primarily due to improvements in orders for refuse trucks, multi-purpose tractors 
and sewer cleaners of $45.0 million, $8.7 million and $4.8 million, respectively. Additionally, aftermarket demand increased by 
$14.2 million. Partially offsetting these improvements was a $5.6 million reduction in orders for street sweepers and a $7.8 
million unfavorable foreign currency translation impact.

Net sales increased by $247.3 million, or 21%, for the year ended December 31, 2023, primarily due to higher sales volumes, 
inclusive of the effects of acquisitions, pricing actions and increased chassis sales. U.S. sales increased by $165.8 million, or 
17%, largely due to a $45.1 million increase in aftermarket revenues and increases in sales of street sweepers, sewer cleaners, 
safe-digging trucks, industrial vacuum loaders, trailers, multi-purpose tractors, road-marking and line-removal equipment and 
refuse trucks of $35.5 million, $28.1 million, $21.4 million, $16.3 million, $10.5 million, $7.8 million, $7.5 million and $6.3 
million, respectively. Partially offsetting these improvements were reductions in shipments of hoists and waterblasting 
equipment of $7.9 million and $5.5 million, respectively. Non-U.S. sales increased by $81.5 million, or 42%, largely due to a 
$21.1 million improvement in aftermarket revenues and increases in sales of refuse trucks, metal extraction support equipment, 
multi-purpose tractors and sewer cleaners of $24.8 million, $17.9 million, $13.6 million and $6.9 million, respectively. Partially 
offsetting these improvements was a $5.9 million reduction in sales of safe-digging trucks and a $6.4 million unfavorable 
foreign currency translation impact.

Cost of sales increased by $162.3 million, or 17%, for the year ended December 31, 2023, primarily related to increased sales 
volumes, inclusive of the effects of acquisitions, increased chassis costs and a $3.2 million increase in depreciation expense, 
partially offset by a $6.2 million favorable foreign currency translation impact. Including these factors, gross profit margin for 
the year ended December 31, 2023 was 23.6%, compared to 21.4% in the prior year, 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 increased by $16.8 million, or 17%, for the year ended December 31, 2023, primarily due to additional costs 
from acquired businesses, as well as increases in sales commissions and incentive-based compensation expense. As a 
percentage of net sales, SEG&A expenses were 7.9% in the current year, compared to 8.1% in the prior year.

Operating income increased by $64.7 million, or 45%, for the year ended December 31, 2023, largely due to a $85.0 million 
increase in gross profit, partially offset by the $16.8 million increase in SEG&A expenses, a $2.3 million increase in 
amortization expense and a $1.2 million increase in acquisition-related costs.

Backlog was $967 million at December 31, 2023, compared to $824 million at December 31, 2022.

Year ended December 31, 2023 vs. year ended December 31, 2022

Total orders increased by $44.1 million, or 18%, for the year ended December 31, 2023. U.S. orders increased by $16.9 million, 
or 11%, compared to the prior year, driven by improvements in orders for public safety equipment, warning systems and 
industrial signaling equipment of $10.8 million, $4.9 million and $1.2 million, respectively. Non-U.S. orders increased by $27.2 
million, or 31%, primarily due to a $23.9 million improvement in orders for public safety equipment, inclusive of a large fleet 
order from a customer in Mexico, as well as a $2.8 million improvement in orders for warning systems.

Net sales increased by $40.6 million, or 17%, for the year ended December 31, 2023, inclusive of the effects of higher sales 
volumes and pricing actions. U.S. sales increased by $21.8 million, or 14%, driven by improvements in sales of public safety

equipment, industrial signaling equipment and warning systems of $12.6 million, $4.7 million and $4.5 million, respectively. 
Non-U.S. sales increased by $18.8 million, or 21%, largely due to improvements in sales of public safety equipment, industrial 
signaling equipment and warning systems of $10.1 million and $6.3 million and $2.3 million, respectively.

Cost of sales increased by $20.3 million, or 13%, for the year ended December 31, 2023, primarily related to higher sales 
volumes. Gross profit margin for the year ended December 31, 2023 was 38.9%, compared to 37.1% in the prior year, with the 
improvement primarily attributable to improved operating leverage from higher sales volumes, benefits from pricing actions 
and lower freight costs.

SEG&A expenses increased by $6.3 million for the year ended December 31, 2023, primarily due to higher sales commissions 
and incentive-based compensation expense. As a percentage of net sales, SEG&A expenses were 19.7% in the current year, 
compared with 20.4% in the prior year. 

Operating income increased by $14.0 million, or 34%, for the year ended December 31, 2023, primarily due to a $20.3 million 
increase in gross profit, partially offset by the $6.3 million increase in SEG&A expenses. 

Backlog was $59 million at December 31, 2023, compared to $55 million at December 31, 2022. 

Corporate Expense

Corporate operating expenses were $39.5 million, $24.5 million and $22.5 million for the years ended December 31, 2023, 
2022 and 2021, respectively. 

For the year ended December 31, 2023, corporate operating expenses increased by $15.0 million compared to the prior year, 
with the increase primarily due to higher post-retirement expenses and increases in incentive-based compensation, stock 
compensation, medical and IT costs, partially offset by a $0.3 million decrease in acquisition-related expenses. During the year 
ended December 31, 2023, the Company recognized a $2.1 million benefit associated with a reduction in the estimated fair 
value of contingent consideration. During the year ended December 31, 2022, the Company received a favorable settlement of 
$1.9 million in a post-closing adjustment dispute associated with the 2021 acquisition of OSW Equipment & Repair, LLC. 
These acquisition-related benefits have been included as a component of Acquisition and integration-related expenses 
(benefits), net on the Consolidated Statements of Operations.

The Company’s hearing loss litigation has historically been managed by the Company’s legal staff resident at the corporate 
office and not by management at either segment. In accordance with Accounting Standards Codification (“ASC”) 280, Segment 
Reporting, which provides that segment reporting should follow the management of the item and that certain expenses may be 
corporate expenses, these legal expenses (which are not part of the normal operating activities of any of our reportable 
segments) are reported and managed as corporate expenses.

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 2022 Credit Agreement will provide funds sufficient for these purposes. 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 $61.0 million, $47.5 million and $40.5 million as of December 31, 2023, 
2022 and 2021, respectively. As of December 31, 2023, $27.8 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 indefinitely 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 were 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 and 
withholding taxes, as applicable, dependent on income tax laws and other circumstances at the time any such amounts were 
repatriated.

Net cash provided by operating activities totaled $194.4 million, $71.8 million and $101.8 million in 2023, 2022 and 2021, 
respectively. The increase in cash generated by operating activities in 2023 compared to the prior year was primarily due to 

23

working capital improvements and higher net income, partially offset by increased rental fleet investments to support strong 
demand for rentals and used equipment and higher income tax payments.

Net cash used for investing activities totaled $83.7 million, $99.7 million and $168.7 million in 2023, 2022 and 2021, 
respectively. In each of the years presented, cash was used to fund the purchase of properties and equipment, with $30.3 
million, $53.0 million and $37.4 million of capital expenditures in 2023, 2022 and 2021, respectively. Capital expenditures in 
2022 included the acquisition of the Company’s University Park, Illinois manufacturing facility for $28 million, and capital 
expenditures in 2021 included the purchase of the Company’s Elgin, Illinois manufacturing facility for $19.8 million. During 
2023, the Company made initial payments of $41.9 million and $13.0 million to acquire Trackless and Blasters. During 2022 
the Company completed the acquisition of TowHaul for initial consideration of $43.3 million. In addition, during 2022 the 
Company paid $4.3 million to acquire certain distribution rights from dealers and funded a $1.6 million post-closing adjustment 
related to the 2021 acquisition of substantially all of the assets and operations of Deist Industries, Inc. In 2021, the Company 
completed three acquisitions for aggregate initial consideration of $131.8 million, excluding cash acquired. 

Net cash of $97.9 million was used for financing activities in 2023, whereas in 2022 and 2021, $35.5 million, and $26.4 
million, respectively, was provided by financing activities. In 2023, the Company paid down $64.1 million of borrowings under 
its revolving credit facility and $0.8 million under its term loan facility, funded cash dividends and share repurchases of $23.8 
million and $5.5 million, respectively, and redeemed $7.0 million of stock in order to remit funds to tax authorities to satisfy 
employees’ tax withholdings following the vesting of stock-based compensation and the exercise of stock options. The 
Company also received $3.9 million from stock option exercises. In 2022, the Company borrowed $81.2 million under its 
revolving credit facility, primarily to fund acquisitions, and received $0.2 million from stock option exercises. The Company 
also funded cash dividends and share repurchases of $21.8 million and $16.1 million, respectively, and redeemed $6.2 million 
of stock in order to remit funds to tax authorities to satisfy employees’ tax withholdings following the vesting of stock-based 
compensation and the exercise of stock options. In 2021, the Company borrowed $70.5 million under its revolving credit 
facility, primarily to fund acquisitions, and received $4.2 million from stock option exercises. The Company also funded cash 
dividends and share repurchases of $22.0 million and $15.4 million, respectively, and redeemed $10.7 million of stock in order 
to remit funds to tax authorities to satisfy employees’ tax withholdings following the vesting of stock-based compensation and 
the exercise of stock options. 

On October 21, 2022, the Company entered into the 2022 Credit Agreement, by and among the Company and certain of its 
foreign subsidiaries (collectively, the “Borrowers”), Wells Fargo Bank, National Association, as administrative agent, swingline 
lender and issuing lender, PNC Bank, National Association and Truist Bank as syndication agents, and the other lenders and 
parties signatory thereto. 

The 2022 Credit Agreement is a senior secured credit facility which provides the Borrowers 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. The Revolver provides for borrowings in the form of loans or letters of 
credit up to the aggregate availability under the facility, with a sub-limit of $100 million for letters of credit. Borrowings can be 
made in denominations of U.S. Dollars, Canadian Dollars, Euros or British Pounds (with borrowings in non-U.S. currencies 
subject to a sublimit of $300 million). In addition, the Company may expand its borrowing capacity under the 2022 Credit 
Agreement by up to the greater of (i) $400 million and (ii) 100% of Consolidated EBITDA for the applicable four-quarter 
period preceding such expansion notice, subject to the approval of the applicable lenders providing such additional borrowings 
in the form of increases to their revolving facility commitment, or funding of incremental term loans. Borrowings under the 
2022 Credit Agreement may be used for working capital and general corporate purposes, including acquisitions. The 2022 
Credit Agreement matures on October 21, 2027.  

The Company’s material domestic subsidiaries provide guarantees for all obligations of the Borrowers under the 2022 Credit 
Agreement, which is secured by a first priority security interest in (i) all existing or hereafter acquired domestic property and 
assets of the Company and material domestic subsidiaries, (ii) the stock or other equity interests in each of the material 
domestic subsidiaries and (iii) 65% of outstanding voting capital stock of certain first-tier foreign subsidiaries, subject to certain 
exclusions.

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.

24

The Company is subject to certain net leverage ratio and interest coverage ratio financial covenants under the 2022 Credit 
Agreement that are to be measured at each fiscal quarter-end. The 2022 Credit Agreement also includes certain “covenant 
holiday” periods, which allow for the temporary increase of the minimum net leverage ratio following the completion of a 
permitted acquisition, or a series of acquisitions, when the aggregate consideration over a period of twelve months exceeds $75 
million. In addition, the 2022 Credit Agreement includes customary negative covenants, subject to certain exceptions, 
restricting or limiting the Company’s and its subsidiaries’ ability to, among other things: (i) make non-ordinary course 
dispositions of assets; (ii) make certain fundamental business changes, such as mergers, consolidations or any similar 
combination; (iii) make restricted payments, including dividends and stock repurchases; (iv) incur indebtedness; (v) make 
certain loans and investments; (vi) create liens; (vii) transact with affiliates; (viii) enter into certain sale/leaseback transactions; 
(ix) make negative pledges; and (x) modify subordinated debt documents.

Under the 2022 Credit Agreement, restricted payments, including dividends and stock repurchases, shall be permitted if (i) the 
Company’s leverage ratio is less than or equal to 3.25x; (ii) the Company is in compliance with all other financial covenants; 
and (iii) there are no existing defaults under the 2022 Credit Agreement. If its leverage ratio is more than 3.25x, the Company is 
still permitted to fund (1) up to $35 million of dividend payments and stock repurchases annually; and (2) additional 
incremental other cash payments up to the greater of $65 million or 5% of consolidated total assets for the term of the 2022 
Credit Agreement.

The 2022 Credit Agreement contains customary events of default. If an event of default occurs and is continuing, the Borrowers 
may be required immediately to repay all amounts outstanding under the 2022 Credit Agreement and the commitments from the 
lenders may be terminated.

The 2022 Credit Agreement amended and restated the Second Amended and Restated Credit Agreement (as amended, the 
“2019 Credit Agreement”), which provided the Company with a $500 million revolving credit facility. 

As of December 31, 2023, there was $173.2 million of cash drawn on the Revolver, $124.2 million outstanding under the term 
loan facility and $9.1 million of undrawn letters of credit under the 2022 Credit Agreement, with $492.7 million of net 
availability for borrowings.

Aggregate maturities of long-term borrowings and finance lease obligations are $4.7 million in 2024, $7.8 million in 2025, 
$10.2 million in 2026 and $276.3 million in 2027. The weighted average interest rate on long-term borrowings was 5.9% at 
December 31, 2023.

The Company paid interest of $22.8 million in 2023, $9.4 million in 2022 and $3.9 million in 2021. 

The Company paid income taxes of $46.2 million in 2023, $26.9 million in 2022 and $35.5 million in 2021. 

Cash dividends of $23.8 million, $21.8 million and $22.0 million were declared and paid to stockholders in 2023, 2022 and 
2021, respectively. 

The Company anticipates that capital expenditures for 2024 will be in the range of $35 million to $40 million. The Company 
believes that its financial resources and major sources of liquidity, including cash flow from operations and borrowing capacity, 
will be adequate to meet its operating needs, capital needs and financial commitments.

(b)  Amounts include contractual obligations associated with lease arrangements with an initial term of twelve months or less, which are not recorded on the 

Consolidated Balance Sheets. For further discussion, see Note 4 – Leases to the accompanying consolidated financial statements.

(c)  Purchase obligations primarily relate to commercial chassis and other contracts in the ordinary course of business.

(d)  The Company expects to contribute up to $5.0 million to the U.S. benefit plan and up to $0.2 million to the non-U.S. benefit plan in 2024, which represent 

the minimum required contributions. Future contributions to the plans will be based on such factors as (i) annual service cost, (ii) the financial return on 
plan assets, (iii) interest rate movements that affect discount rates applied to plan liabilities and (iv) the value of benefit payments made. Due to the high 
degree of uncertainty regarding the potential future cash outflows associated with these plans, the Company is unable to provide a reasonably reliable 
estimate of the amounts and periods in which any additional liabilities might be paid.

(e)  Represents the fair value of the contingent earn-out payments associated with the Deist, Blasters and Trackless acquisitions. For further discussion, see 

Note 2 – Acquisitions to the accompanying consolidated financial statements.

(f)  As of December 31, 2023, the Company had a liability of approximately $1.1 million for unrecognized tax benefits, including penalties and interest. For 
further discussion, see Note 10 – Income Taxes to the accompanying consolidated financial statements. Due to the uncertainties related to these tax 
matters, the Company generally cannot make a reasonably reliable estimate of the period of cash settlement for this liability. As such, the potential future 
cash outflows are not included in the table above.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles 
(“GAAP”) requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities, 
(ii) 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. The Company 
considers the following policies to be the most critical in understanding the judgments that are involved in the preparation of the 
Company’s consolidated financial statements and the uncertainties that could impact the Company’s financial condition, results 
of operations or cash flow.

Goodwill

Goodwill represents the excess of the cost of an acquired business over the amounts assigned to its net assets. Goodwill is not 
amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently if indicators of impairment 
exist. The Company performed its annual goodwill impairment test as of October 31, 2023.

In testing the goodwill of its reporting units for potential impairment, the Company applies either a qualitative or quantitative 
test, in accordance with ASC 350, Intangibles – Goodwill and Other.  

A qualitative approach may be applied when the Company concludes that it is not “more likely than not” that the fair value of a 
reporting unit is less than its carrying value. In conducting a qualitative assessment, the Company analyzes a variety of events 
or factors that may influence the fair value of the reporting unit, including, but not limited to: the results of prior quantitative 
assessments performed; changes in the carrying amount; actual and projected financial performance; relevant market data for 
both the Company and its guideline comparable companies; industry outlook; and macroeconomic conditions. Significant 
judgment is used to evaluate the totality of these events and factors to make the determination of whether it is more likely than 
not that the fair value of the reporting unit is less than its carrying value. In this situation, the Company would not be required to 
perform the quantitative impairment test described below.

A quantitative approach is performed by comparing the fair value of a reporting unit with its carrying amount. If the fair value 
of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and no impairment charge is 
required. If the carrying amount of a reporting unit exceeds its fair value, this difference is recorded as an impairment charge 
not to exceed the carrying amount of goodwill. The Company generally determines the fair value of its reporting units using 
both the income and market approaches.

Under the income approach, the key assumptions include projected sales and earnings before interest, income taxes, 
depreciation and amortization (“EBITDA”). These assumptions are determined by management utilizing our internal operating 
plan, including growth rates for revenues and margin assumptions. An additional key assumption under this approach is the 
discount rate, which is determined by reviewing current risk-free rates of capital and current market interest rates and by 
evaluating the risk premium relevant to the reporting unit. If the Company’s assumptions relative to growth rates were to 
change, the fair value calculation may change, which could result in impairment.

Under the market approach, the Company estimates fair value using marketplace fair value data from within a comparable 
industry grouping of publicly traded companies and from pricing multiples implied from sales of companies similar to the 
Company’s reporting units. The Company’s selection of comparable guideline companies is a key assumption underlying the 
market approach. Similar to the income approach discussed above, sales, cost of sales, operating expenses, EBITDA and their 
respective growth rates are also key assumptions utilized. The market prices of the Company’s common stock and other 
guideline companies are additional key inputs. If these market prices increase, the estimated market value would increase. 
Conversely, if market prices decrease, the estimated market value would decrease.

The results of these two methods are weighted based upon management’s evaluation of the relevance of the two approaches. 

Although the Company believes its estimates of fair value are reasonable, actual financial results could differ from estimated 
financial results due to the inherent uncertainty involved in making such estimates. Changes in assumptions concerning future 
financial results or other underlying assumptions could have a significant impact on either the fair value of the reporting units, 
the amount of any goodwill impairment charge, or both. The Company also compares the sum of the estimated fair values of its 
reporting units to the overall fair value of the Company implied by its market capitalization. This comparison provides an 
indication that, in total, assumptions and estimates are reasonable. Future declines in the overall market value of the Company 
may also result in a conclusion that the fair value of one or more reporting units has declined below its carrying value. 

In 2023, the Company performed a combination of qualitative and quantitative impairment tests to assess the goodwill of its 
reporting units for potential impairment. For one reporting unit, a quantitative impairment test was performed, using a 
combination of the income and market approaches to determine the fair value of its reporting unit. The valuation was prepared 

27

by a third-party valuation specialist. One measure of the sensitivity of assumptions used in the impairment analysis is the 
amount by which the reporting unit “passed” (fair value exceeds the carrying value). The fair value of the reporting unit 
exceeded its carrying value by more than 20%. Therefore, no impairment was recognized. For its other reporting units, the 
Company applied the qualitative approach and concluded that it was not “more likely than not” that the fair value of the  
reporting units were less than their carrying values. Accordingly, further quantitative testing was not required to be performed. 

The Company had no goodwill impairments in 2023, 2022 or 2021. For all reporting units, a 10% decrease in the estimated fair 
value would have had no effect on the carrying value of goodwill at the annual measurement date in 2023. However, adverse 
changes to the Company’s business environment and future cash flow could cause us to record impairment charges in future 
periods, which could be material. 

See Note 8 – Goodwill and Other Intangible Assets to the accompanying consolidated financial statements for a summary of the 
Company’s goodwill by segment.

Indefinite-lived Intangible Assets

An intangible asset determined to have an indefinite useful life is not amortized. Indefinite-lived intangible assets are tested for 
impairment on an annual basis at year-end, or more frequently if an event occurs or circumstances change that indicate the fair 
value of an indefinite-lived intangible asset could be below its carrying amount. The Company’s indefinite-lived intangible 
assets include trade names associated with acquisitions. 

In testing the indefinite-lived intangibles assets for potential impairment, the Company applies either a qualitative test, or a 
quantitative test, in accordance with ASC 350, Intangibles — Goodwill and Other. A qualitative approach may be applied when 
the Company concludes that it is not “more likely than not” that the fair value of the indefinite-lived intangible assets are less 
than their carrying value. A quantitative impairment test consists of comparing the fair value of the indefinite-lived intangible 
asset with its carrying amount. An impairment loss would be recognized for the carrying amount in excess of its fair value. 

Significant judgment is applied when evaluating whether an intangible asset has an indefinite useful life and in testing for 
impairment. The Company primarily uses the relief from royalty model to estimate the fair value of the indefinite-lived 
intangible assets. The relief from royalty model requires management to make a number of business and valuation assumptions 
including future revenue growth and royalty rates. 

In 2023, the Company performed a combination of qualitative and quantitative impairment tests over its indefinite-lived 
intangible assets. The fair value of the indefinite-lived intangible asset that was quantitatively tested for impairment exceeded 
its carrying value by approximately 40%, and, therefore, no impairment was recognized. This valuation was prepared by a 
third-party valuation specialist. Further, the Company concluded that it was not “more likely than not” that the fair value of 
indefinite-lived intangible assets that were qualitatively tested for impairment were less than the carrying amounts. 
Accordingly, further quantitative testing was not required to be performed.

The Company had no indefinite-lived intangible asset impairments in 2023, 2022 or 2021. Although the Company believes its 
estimates of fair value are reasonable, actual financial results could differ from estimated financial results due to the inherent 
uncertainty involved in making such estimates. The use of alternative estimates and assumptions could increase or decrease the 
estimated fair value of the assets and potentially result in different impacts to the Company’s results of operations. Actual 
results may differ from the Company’s estimates.

See Note 8 – Goodwill and Other Intangible Assets to the accompanying consolidated financial statements for a summary of the 
Company’s indefinite-lived intangible assets.

Item 7A.    Quantitative and Qualitative Disclosures about Market Risk.

The Company is subject to market risk associated with changes in interest rates and foreign exchange rates. To mitigate this 
risk, the Company may utilize derivative financial instruments, including interest rate swaps and foreign currency forward 
contracts. The Company does not hold or issue derivative financial instruments for trading or speculative purposes and is not 
party to leveraged derivatives contracts.

Interest Rate Risk

The Company has certain debt instruments which subject it to market risk associated with movements in interest rates. The fair 
value of the Company’s total debt obligations held at December 31, 2023 was $299.0 million. From time to time, the Company 
may enter into interest rate swaps as a means of fixing the floating interest rate component on its variable-rate debt. At 
December 31, 2023, the Company had two interest rate swaps outstanding. The swaps had an aggregate notional amount of 
$150.0 million, and fixed the floating interest rate component on $150.0 million of the Company’s variable-rate debt. See 
Note 9 – Debt to the accompanying consolidated financial statements for a description of the Company’s debt agreements and 
interest rate swaps that were in place during 2023. A hypothetical 1% increase or decrease in variable interest rates on the 
Company’s total debt obligations as of December 31, 2023 would increase or decrease annual interest expense by 
approximately $1.5 million.

Foreign Exchange Rate Risk

Although the majority of the Company’s sales, expenses and cash flow are transacted in U.S. Dollars, the Company has 
exposure to changes in foreign exchange rates, primarily the Canadian Dollar, Euro and British Pound. The impact of currency 
movements on the Company’s financial results is largely mitigated by natural hedges in its operations. The Canadian operations 
of JJE and Trackless primarily conduct business in Canadian dollars. Almost all other sales of product from the U.S. to other 
parts of the world are denominated in U.S. dollars. Sales from and within other currency zones are predominantly transacted in 
the currency of the country sourcing the product or service. Approximately 78% of the Company’s net sales are conducted 
within the U.S. and are transacted in U.S. dollars. The Company estimates that a 10% appreciation of the U.S. dollar against 
other currencies would reduce full-year net sales by approximately 2% and operating income by approximately 1%.

The Company may also have foreign currency exposures related to buying and selling in currencies other than the local 
currency in which it operates and to certain balance sheet positions. If such transactional or balance sheet exposures are 
material, the Company may enter into matching foreign currency forward contracts from time to time to protect against 
variability in exchange rates.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Federal Signal Corporation

Oak Brook, Illinois

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Federal Signal Corporation and subsidiaries (the 
“Company”) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, 
stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes  
(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material 
respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash 
flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally 
accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in 
Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission and our report dated February 27, 2024, expressed an unqualified opinion on the Company's internal control over 
financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included 
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included 
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall 
presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that 
was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that 
are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and 
we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the 
accounts or disclosures to which it relates. 

Goodwill - Refer to Notes 1 and 8 to the financial statements 

Critical Audit Matter Description 

In testing the goodwill of its reporting units for potential impairment, the Company applies either a qualitative or quantitative 
test, in accordance with ASC 350, Intangibles – Goodwill and Other. A qualitative approach may be applied when the 
Company concludes that it is not “more likely than not” that the fair value of a reporting unit is less than its carrying value. 
A quantitative approach is performed by comparing the fair value of a reporting unit with its carrying amount (“quantitative 
assessment”). 

For reporting units tested for impairment using the quantitative assessment, the Company determines the fair value of each 
reporting unit using both the income and market approaches. The income approach requires management to make a number of 
business and valuation assumptions for each reporting unit including annual assumptions of projected sales, cost of sales, 
operating expenses, earnings before interest, income taxes, depreciation, and amortization (“EBITDA”), and discount rates. The 
market approach requires management to estimate fair value using marketplace fair value data derived from a comparable 
industry grouping of publicly traded companies and from pricing multiples implied from sales of companies similar to the 
Company’s reporting units (“market multiples”). No impairment was recognized in 2023. 

31

We identified the valuation of goodwill for one of the Company’s reporting units as a critical audit matter due to the reporting 
unit’s historical performance as compared to projections and because the determination of reporting unit fair value was based 
on significant assumptions that are sensitive to changes and are affected by expected future market and economic conditions. 
Auditing management’s judgments used in the quantitative assessment regarding significant assumptions related to projected 
sales and EBITDA (“forecasts”) as well as the selection of market multiples applied to management’s projected sales and 
EBITDA estimates for this reporting unit required a high degree of auditor judgment and an increased extent of effort, including 
the need to involve our fair value specialists. 

How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to the Company’s forecasts and the selection of market multiples for this reporting unit included 
the following, among others: 

• We tested the design and operating effectiveness of controls over the annual goodwill impairment assessment, 

including those over the forecasts and the market multiples. 

• We evaluated management’s ability to accurately forecast projected sales and EBITDA by comparing actual results to 

management’s historical forecasts. 

• We evaluated the reasonableness of management’s forecasts by comparing the forecasts to:
Internal communications to management and the Board of Directors. 
Historical results, third-party economic research, industry performance, and peer company performance. 
Actual results from the October 31, 2023 annual measurement date to December 31, 2023. 

◦
◦
◦

• We performed sensitivity analyses to evaluate the risk of impairment if key assumptions are changed. 
• With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodology and 

(2) market multiples by performing certain procedures, that included:

◦

◦

◦

Evaluating whether the fair value models being used are appropriate considering the Company’s 
circumstances and valuation premise identified.
Evaluating the market multiples by considering (1) the selected comparable industry grouping of publicly 
traded companies, (2) the selected sales of companies similar to the Company’s reporting units, and (3) the 
adjustments made for differences in growth prospects and risk profiles between the reporting unit and the 
comparable industry grouping of publicly traded companies. 
Testing the underlying source information and mathematical accuracy of the calculations.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Federal Signal Corporation

Oak Brook, Illinois

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Federal Signal Corporation and subsidiaries (the “Company”) 
as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in 
Internal Control — Integrated Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our 
report dated February 27, 2024, expressed an unqualified opinion on those financial statements. 

As described in Management's Annual Report on Internal Control over Financial Reporting, management excluded from its 
assessment, the internal control over financial reporting at Trackless Vehicles Limited, Trackless Vehicles Asset Corp, and 
Work Equipment Ltd. (collectively, “Trackless”), which were acquired on April 3, 2023, and whose financial statements 
constitute 2% of total assets and 1% of net sales of the consolidated financial statement amounts (excluding goodwill and 
intangible assets, which were integrated into the Company’s control environment) for the year ended December 31, 2023. 
Accordingly, our audit did not include the internal control over financial reporting at Trackless.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s 
Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s 
internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk 
that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit 
provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that the controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Description of the Business

Federal Signal Corporation was founded in 1901 and was reincorporated as a Delaware corporation in 1969. References herein 
to the “Company,” “we,” “our” or “us” refer collectively to Federal Signal Corporation and its subsidiaries.

Products manufactured and services rendered by the Company are divided into two reportable segments: Environmental 
Solutions Group and Safety and Security Systems Group. The individual operating businesses are organized as such because 
they share certain characteristics, including technology, marketing, distribution and product application, which create long-term 
synergies. 

The Company’s fiscal year ends on December 31. All references to 2023, 2022 and 2021 relate to the fiscal year unless 
otherwise indicated.

Basis of Presentation and Consolidation

The accompanying consolidated financial statements represent the consolidation of Federal Signal Corporation and its 
subsidiaries and have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange 
Commission (“SEC”) and in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”).

Intercompany balances and transactions have been eliminated in consolidation. In addition, certain prior year amounts have 
been reclassified to conform to current year presentation. 

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 
2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands annual and interim 
disclosure requirements for reportable segments, including enhanced disclosures regarding significant segment expenses. ASU 
2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning 
after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting this 
guidance on its financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topics 740): Improvements to Income Tax Disclosures, 
which expands the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes 
paid. ASU 2023-09 is effective prospectively for annual periods beginning after December 15, 2024, with early adoption and 
retrospective application permitted. The Company is currently evaluating the impact of adopting this guidance on its financial 
statement disclosures.

Non-U.S. Operations

Assets and liabilities of non-U.S. subsidiaries, other than those whose functional currency is the U.S. dollar, are translated at 
current exchange rates with the related translation adjustments reported in stockholders’ equity as a component of Accumulated 
other comprehensive loss. Accounts within the Consolidated Statements of Operations are translated at the average exchange 
rate during the period. Non-monetary assets and liabilities are translated at historical exchange rates. 

The Company incurs foreign currency transaction gains or losses, related to transactions that are denominated in a currency 
other than the functional currency, which are recognized in the Consolidated Statements of Operations as a component of Other 
expense (income), net. For the years ended December 31, 2023 and 2022, the Company realized foreign currency transaction 
losses of $0.6 million and $0.2 million, respectively. For the year ended December 31, 2021, the Company realized foreign 
currency transaction gains of $0.3 million. 

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 

39

FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

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.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less, when purchased, to be cash 
equivalents. The carrying amount of cash and cash equivalents approximates fair value because of the short-term maturity and 
highly liquid nature of these instruments.

Accounts Receivable

The Company carries accounts receivable at the face amount less an allowance for doubtful accounts for estimated losses as a 
result of a customer’s inability to make required payments. Management evaluates the aging of the accounts receivable 
balances, the financial condition of its customers, historical trends and the time outstanding of specific balances to estimate the 
amount of accounts receivables that may not be collected in the future and records the appropriate provision.

Inventories

The Company’s inventories are valued at the lower of cost and net realizable value. Cost is determined using the first-in, first-
out method. Included in the cost of inventories are raw materials, direct wages and associated production costs.

Properties and Equipment

Properties and equipment are stated at cost, net of accumulated depreciation. Depreciation is recorded using the straight-line 
method over the estimated useful lives of the assets. Useful lives generally range from eight to 40 years for buildings and three 
to 15 years for machinery and equipment. Leasehold improvements are depreciated over the shorter of the remaining life of the 
lease or the useful life of the improvement. Depreciation expense is primarily included as a component of Cost of sales on the 
Consolidated Statements of Operations, with depreciation expense associated with certain assets used for administrative 
purposes being presented within Selling, engineering, general and administrative (“SEG&A”) expenses. Depreciation expense, 
which includes depreciation on rental equipment, was $45.2 million, $41.8 million and $39.5 million for the years ended 
December 31, 2023, 2022 and 2021, respectively.

Properties and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying 
amount may not be recoverable. 

Rental Equipment

The Company enters into lease agreements with customers related to the rental of certain equipment. All of these leasing 
agreements are classified as operating leases and are for periods generally not to exceed five years. In accounting for these 
leases, the cost of the equipment purchased or manufactured by the Company is recorded as an asset and is depreciated over its 
estimated useful life. Rental income is recognized ratably over the term of the underlying leases.

Rental equipment is depreciated to an estimated residual value on a straight-line basis over the estimated useful lives of the 
assets and is reviewed for potential impairment whenever an event occurs or circumstances change that indicate the carrying 
amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible 
impairment, the Company first compares non-discounted cash flows expected to be generated by that asset group to its carrying 
amount. If the carrying amount of the long-lived asset or asset group is not recoverable on a non-discounted cash flow basis, an 
impairment is recognized to the extent that the carrying amount exceeds fair value. Fair value is determined through various 
valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as 
considered necessary.

Rental equipment includes certain equipment that is manufactured by the Company and subsequently transferred to the rental 
fleet, as well as equipment purchased from third-party manufacturers, for the purpose of renting to end-customers. The related 
cash flow activity associated with these transactions is reflected within operating activities on the Consolidated Statements of 
Cash Flows.

Goodwill

Goodwill represents the excess of the cost of an acquired business over the amounts assigned to its net assets. Goodwill is not 
amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently if indicators of impairment 
exist. The Company performed its annual goodwill impairment test as of October 31, 2023.

In testing the goodwill of its reporting units for potential impairment, the Company applies either a qualitative or quantitative 
test, in accordance with Accounting Standards Codification (“ASC”) 350, Intangibles – Goodwill and Other.  

A qualitative approach may be applied when the Company concludes that it is not “more likely than not” that the fair value of a 
reporting unit is less than its carrying value. In this situation, the Company would not be required to perform the quantitative 
impairment test described below.

A quantitative approach is performed by comparing the fair value of a reporting unit with its carrying amount. If the fair value 
of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and no impairment charge is 
required. If the carrying amount of a reporting unit exceeds its fair value, this difference is recorded as an impairment charge 
not to exceed the carrying amount of goodwill. The Company generally determines the fair value of its reporting units using 
both the income and market approaches.

Under the income approach, the key assumptions include projected sales, earnings before interest, income taxes, depreciation 
and amortization (“EBITDA”) and the discount rate. Under the market approach, the Company estimates fair value using 
marketplace fair value data from within a comparable industry grouping. The results of these two methods are weighted based 
upon management’s evaluation of the relevance of the two approaches. 

In 2023, the Company performed a combination of qualitative and quantitative impairment tests to assess the goodwill of its 
reporting units for potential impairment. For one reporting unit, a quantitative impairment test was performed, using a 
combination of the income and market approaches to determine the fair value of its reporting unit. The valuation was prepared 
by a third-party valuation specialist. One measure of the sensitivity of assumptions used in the impairment analysis is the 
amount by which the reporting unit “passed” (fair value exceeds the carrying value). The fair value of the reporting unit 
exceeded its carrying value by more than 20% and, therefore, no impairment was recognized. For its other reporting units, the 
Company applied the qualitative approach and concluded that it was not “more likely than not” that the fair value of the  
reporting units were less than their carrying values. Accordingly, further quantitative testing was not required to be performed. 

The Company had no goodwill impairments in 2023, 2022 or 2021. See Note 8 – Goodwill and Other Intangible Assets for a 
summary of the Company’s goodwill by segment.

Intangible Assets

Definite-lived intangible assets are amortized on a straight-line basis over the estimated useful lives and are tested for 
impairment if indicators exist in a manner similar to that described above for Rental Equipment. 

Indefinite-lived intangible assets are tested for impairment on an annual basis at October 31, or more frequently if an event 
occurs or circumstances change that indicate the fair value of an indefinite-lived intangible asset could be below its carrying 
amount. In testing the indefinite-lived intangibles assets for potential impairment, the Company applies either a qualitative test, 
or a quantitative test, in accordance with ASC 350. A qualitative approach may be applied when the Company concludes that it 
is not “more likely than not” that the fair value of the indefinite-lived intangible assets are less than their carrying value. A 
quantitative impairment test consists of comparing the fair value of the indefinite-lived intangible asset with its carrying 
amount. An impairment loss would be recognized for the carrying amount in excess of its fair value.  

In 2023, the Company performed a combination of qualitative and quantitative impairment tests over its indefinite-lived 
intangible assets. The fair value of the indefinite-lived intangible asset that was quantitatively tested for impairment exceeded 
its carrying value by approximately 40%, and, therefore, no impairment was recognized. Further, the Company concluded that 
it was not “more likely than not” that the fair value of indefinite-lived intangible assets that were qualitatively tested for 
impairment were less than the carrying amounts. Accordingly, further quantitative testing was not required to be performed.

The Company had no indefinite-lived intangible asset impairments in 2023, 2022 or 2021. See Note 8 – Goodwill and Other 
Intangible Assets for a summary of the Company’s intangible assets.

FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

Warranties

Warranties are classified as either assurance-type or service-type warranties. A warranty is considered an assurance-type 
warranty if it provides the customer with assurance that the product will function as intended. A warranty that goes above and 
beyond ensuring basic functionality is considered a service-type warranty. The Company offers certain limited warranties that 
are assurance-type warranties and extended service arrangements that are service-type warranties. Assurance-type warranties 
are not accounted for as separate performance obligations under the revenue model. If a service-type warranty is sold with a 
product or separately, revenue is recognized over the life of the warranty. 

Sales of many of the Company’s products include assurance-type warranties based on terms that are generally accepted in the 
Company’s marketplaces. The Company records provisions for estimated warranty costs, which are included within Cost of 
sales, at the time of sale based on historical experience. The Company periodically adjusts these provisions to reflect actual 
experience. Infrequently, a material warranty issue can arise which is beyond the scope of the Company’s historical experience. 
The Company records costs related to these issues as they become probable and estimable.

The Company also sells optional service-type warranty contracts that extend coverage beyond the initial term of the express 
warranty period. At the time of sale, revenue related to the service-type warranty contract is deferred and typically recognized 
as revenue on a straight-line basis over the life of the contract. As of December 31, 2023 and 2022, deferred revenue associated 
with service-type warranty contracts was $4.3 million and $4.1 million, respectively, and was included within Other current 
liabilities and Other long-term liabilities on the Consolidated Balance Sheets. Costs under service-type warranty contracts are 
expensed as incurred. 

Workers’ Compensation and Product Liability Reserves

Due to the nature of the Company’s manufacturing and products, the Company is subject to claims for workers’ compensation 
and product liability in the normal course of business. The Company is self-funded for a portion of these claims. The Company 
establishes a reserve using a third-party actuary for any known outstanding matters, including a reserve for claims incurred but 
not yet reported. The amount and timing of cash payments relating to these claims are considered to be reliably determinable 
given the nature of the claims and historical claim volumes to support the actuarial assumptions and judgments used to derive 
the expected loss payment patterns. As such, the reserves recorded are discounted using a risk-free rate that matches the average 
duration of the claims.

The Company has not established a reserve for potential losses resulting from the firefighter hearing loss litigation, with the 
exception of certain estimated losses that have been recognized related to settlement discussions (see Note 13 – Legal 
Proceedings). If the Company is not successful in its defense after exhausting all appellate options, it would record a charge for 
such claims, to the extent they exceed insurance recoveries, when the related losses become probable and estimable.

Pensions

The Company sponsors domestic and foreign defined benefit pension plans. Key assumptions used in the accounting for these 
employee benefit plans include the discount rate, expected long-term rate of return on plan assets and estimates of future 
mortality of plan participants. 

The weighted-average discount rate used to measure pension liabilities and costs is selected using a hypothetical portfolio of 
high-quality bonds that would provide the necessary cash flow to match the projected benefit payments of the plans. The 
discount rate represents the rate at which our benefit obligations could effectively be settled as of the year-end measurement 
date. The weighted-average discount rate used to measure pension liabilities decreased from 2022 to 2023. See Note 11 – 
Pension and Other Post-Employment Plans for further discussion.

The expected long-term rate of return on plan assets is based on historical and expected returns for the asset classes in which the 
plans are invested. The Company references published mortality tables and scales in determining its estimate of future 
mortality.

Revenue Recognition

See Note 3 – Revenue Recognition for discussion regarding the Company’s revenue recognition accounting policies.

Product Shipping Costs

Product shipping costs are expensed as incurred and are included within Cost of sales.

Research and Development

The Company invests in research to support development of new products and the enhancement of existing products and 
services. Expenditures for research and development by the Company were $12.4 million in 2023, $11.5 million in 2022 and 
$11.4 million in 2021, and are included within SEG&A expenses in the Consolidated Statements of Operations.

Stock-Based Compensation Plans

The Company has various stock-based compensation plans, described more fully in Note 15 – Stock-Based Compensation. 
Stock-based compensation expense is recorded net of estimated forfeitures in the Company’s Consolidated Statements of 
Operations. The Company estimates the forfeiture rate based on historical forfeitures of equity awards and adjusts the rate to 
reflect changes in facts and circumstances, if any. The Company revises its estimated forfeiture rate if actual forfeitures differ 
from its initial estimates.

Income Taxes

The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized 
for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of 
existing assets and liabilities and their respective tax bases and tax benefit carryforwards. Deferred tax assets and liabilities at 
the end of each period are determined using enacted tax rates expected to apply to taxable income in the period in which the 
deferred tax liability or asset is expected to be settled or realized. A valuation allowance is established or maintained when, 
based on currently available information and other factors, it is more likely than not that all or a portion of a deferred tax asset 
will not be realized.

The Company files a consolidated U.S. federal income tax return for Federal Signal Corporation and its eligible domestic 
subsidiaries. The Company’s non-U.S. subsidiaries file income tax returns in their respective local jurisdictions. The Company 
accounts for taxes on Global Intangible Low-Taxed Income (“GILTI”) as a period expense in the year in which it is incurred.

Accounting standards on accounting for uncertainty in income taxes address the determination of whether tax benefits claimed 
or expected to be claimed on a tax return should be recorded in the consolidated financial statements. Under the guidance on 
accounting for uncertainty in income taxes, the Company may recognize the tax benefit from an uncertain tax position only if it 
is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits 
of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on 
the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company presents 
interest and penalties related to income tax matters as a component of Income tax expense on the Consolidated Statements of 
Operations.

Litigation Contingencies

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. The Company believes, based on current 
knowledge and after consultation with counsel, that the outcome of such claims and actions in the aggregate will not have an 
adverse effect on the Company’s financial position, results of operations or cash flows. 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. Professional legal fees are expensed when incurred. The Company accrues for 
contingent losses when such losses are probable and reasonably estimable. In the event that estimates or assumptions of 
contingent losses are different from actual results, adjustments are made in subsequent periods to reflect more current 
information.

NOTE 2 – ACQUISITIONS

The Company’s acquisitions are accounted for in accordance with ASC 805, Business Combinations. The acquisitions 
completed in the periods presented, as described in further detail within, were accounted for as business combinations in 
accordance with ASC 805. In accordance with this guidance, the fair value of consideration transferred is allocated to assets 
acquired and liabilities assumed based on their estimated fair values as of the completion of the acquisition, with the remaining 
amount recognized as goodwill. A single estimate of fair value results from a complex series of judgments about future events

Under ASC 805-10, acquisition-related costs (e.g., advisory, legal, valuation and other professional fees) are not included as a 
component of consideration transferred, but are accounted for as expenses in the periods in which the costs are incurred. 
Acquisition-related costs are included as a component of Acquisition and integration-related expenses (benefits), net on the 
Consolidated Statements of Operations. 

Acquisitions Completed in 2023

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, and the wholly-owned subsidiary Work Equipment Ltd. (collectively, “Trackless”), 
a leading Canadian manufacturer of off-road, multi-purpose 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 assets and liabilities of Trackless have been consolidated into the Company’s Consolidated Balance Sheet as of December 
31, 2023, and the post-acquisition results of operations have been included in the Consolidated Statements of Operations, within 
the Environmental Solutions Group. 

The initial cash consideration paid by the Company to acquire Trackless was C$56.3 million (approximately $41.9 million), 
inclusive of certain closing adjustments. In addition, there is a contingent earn-out payment of up to C$6.0 million 
(approximately $4.5 million), based upon the achievement of certain financial targets over a specified performance period. The 
purchase price was funded through existing cash and borrowings under the Company’s credit agreement.

As of December 31, 2023, the Company’s purchase price allocation 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-K. 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, including the third-party valuation of acquired intangible assets and contingent consideration, 
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, but not more than one year from the acquisition date.

On January 3, 2023, the Company completed the acquisition of substantially all the assets and operations of Blasters, Inc. and 
Blasters Technologies, LLC (collectively, “Blasters”), a leading U.S. manufacturer of truck-mounted waterblasting equipment. 
The Company expects that the Blasters 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 Blasters have been consolidated into the Company’s Consolidated Balance Sheet as of December

payment of up to $8.0 million, based upon the achievement of certain financial targets over a specified performance period. The

Acquisitions Completed in 2022

Acquisition of TowHaul

On October 3, 2022, the Company completed the acquisition of substantially all the assets and operations of TowHaul 
Corporation (“TowHaul”). TowHaul is a leading manufacturer of off-road towing and hauling equipment. The TowHaul

The cash consideration paid by the Company to acquire TowHaul was $43.3 million, which was funded through existing cash 
and borrowings under the Company’s revolving credit facility.

During the year ended December 31, 2023, the Company recognized measurement period adjustments, which primarily resulted 
from obtaining a third-party valuation of acquired intangible assets, that resulted in a $7.5 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 Consolidated Statements of Operations for the year ended December 31, 2023. As of December 31, 2023, the

NOTE 3 – REVENUE RECOGNITION

Revenue is recognized when performance obligations under the terms of a contract with the customer are satisfied; generally 
this occurs at a point in time, with the transfer of control of the Company’s products or services to customers. For most of the 
Company’s product sales, these criteria are met at the time the product is shipped; however, occasionally control passes later or 

50

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

earlier than shipment due to customer contract or letter of credit terms. In circumstances where credit is extended, payment 
terms generally range from 30 to 120 days and customer deposits may be required. 

Revenue is measured as the amount of consideration the Company expects to be entitled to in exchange for transferring 
products or providing services. Expected returns and allowances are estimated and recognized based primarily on an analysis of 
historical experience, with Net sales presented net of such returns and allowances.

Net sales include sales of products and billed freight related to product sales. Freight has not historically comprised a material 
component of Net sales. The Company has elected to account for such shipping and handling activities as a fulfillment cost and 
not as a separate performance obligation. Taxes collected from customers and remitted to governmental authorities are recorded 
on a net basis and are excluded from Net sales.

Information relating to the disaggregation of Net sales by geographic region, based on the location of the end-customer, is 
included in Note 17 – Segment Information. The following table presents the Company’s Net sales disaggregated by major 
product line:

Contract Balances

The Company recognizes contract liabilities when cash payments, such as customer deposits, are received in advance of the 
Company’s satisfaction of the related performance obligations. Contract liabilities are recognized as Net sales when the related 
performance obligations are satisfied, which generally occurs within three to six months of the cash receipt. Contract liability 
balances are not materially impacted by any other factors. The Company’s contract liabilities were $30.9 million and $28.9 
million, as of December 31, 2023 and 2022, respectively. Contract assets, such as unbilled receivables, were not material as of 
any of the periods presented herein.

As the Company’s standard payment terms are less than a year, the Company has elected the practical expedient under ASC 
606-10-32-18 to not assess whether a contract has a significant financing component.

The Company has also elected the practical expedient under ASC 340-40-25-4 and recognizes the incremental costs of 
obtaining a contract, such as sales commissions, as expense when incurred as the amortization period of the asset that otherwise 
would have been recognized is one year or less. 

Further, as permitted by ASC 606-10-50-14, the Company does not disclose the value of its remaining performance obligations 
for contracts with an original expected duration of one year or less.

NOTE 4 – LEASES

The Company leases certain facilities within the U.S., Europe and Canada from which the Company manufactures vehicles and 
equipment, and provides sales, service and/or equipment rentals. Some of the Company’s lease agreements contain options to 
renew. The Company also leases vehicles and various other equipment. The Company’s lease agreements may contain lease 
and non-lease components, which are accounted for separately. Leases with an initial term of twelve months or less are not 
recorded on the Consolidated Balance Sheets.

In connection with acquisitions completed in recent years, the Company has entered into certain lease agreements for facilities 
owned by affiliates of the sellers. All lease agreements contain an annual rent that is considered to be market-based. Total rent 
paid under these arrangements was $2.3 million, $2.8 million and $2.5 million during the years ended December 31, 2023, 2022 
and 2021, respectively. The Company’s total lease liabilities under these agreements were $4.2 million and $6.9 million as of 
December 31, 2023 and 2022, respectively.

The Company determines if an arrangement is a lease at inception. Operating lease right-of-use assets represent the Company’s 
right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease 
payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement 
date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an 
implicit rate, the Company uses its incremental collateralized borrowing rate based on the information available at the 
commencement date in determining the present value of lease payments. Implicit rates are used when readily determinable. The 
Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will 
exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the respective lease 
term.

The following table summarizes the Company’s total lease costs and supplemental cash flow information arising from operating 
lease transactions:

On October 21, 2022, the Company entered into the Third Amended and Restated Credit Agreement (the “2022 Credit 
Agreement”), by and among the Company and certain of its foreign subsidiaries (collectively, the “Borrowers”), Wells Fargo 
Bank, National Association, as administrative agent, swingline lender and issuing lender, PNC Bank, National Association and 
Truist Bank as syndication agents, and the other lenders and parties signatory thereto. 

The 2022 Credit Agreement is a senior secured credit facility which provides the Borrowers 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. The Revolver provides for borrowings in the form of loans or letters of 
credit up to the aggregate availability under the facility, with a sub-limit of $100 million for letters of credit. Borrowings can be 
made in denominations of U.S. Dollars, Canadian Dollars, Euros or British Pounds (with borrowings in non-U.S. currencies 
subject to a sublimit of $300 million). In addition, the Company may expand its borrowing capacity under the 2022 Credit 
Agreement by up to the greater of (i) $400 million and (ii) 100% of Consolidated EBITDA for the applicable four-quarter 
period preceding such expansion notice, subject to the approval of the applicable lenders providing such additional borrowings 
in the form of increases to their revolving facility commitment, or funding of incremental term loans. Borrowings under the 
2022 Credit Agreement may be used for working capital and general corporate purposes, including acquisitions. The 2022 
Credit Agreement matures on October 21, 2027.  

The Company’s material domestic subsidiaries provide guarantees for all obligations of the Borrowers under the 2022 Credit 
Agreement, which is secured by a first priority security interest in (i) all existing or hereafter acquired domestic property and 
assets of the Company and material domestic subsidiaries, (ii) the stock or other equity interests in each of the material 
domestic subsidiaries and (iii) 65% of outstanding voting capital stock of certain first-tier foreign subsidiaries, subject to certain 
exclusions.

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 to be measured at each fiscal quarter-end. The Company was in compliance with all such covenants as of 
December 31, 2023. The 2022 Credit Agreement also includes certain “covenant holiday” periods, which allow for the 
temporary increase of the minimum net leverage ratio following the completion of a permitted acquisition, or a series of 
acquisitions, when the aggregate consideration over a period of twelve months exceeds $75 million. In addition, the 2022 Credit 
Agreement includes customary negative covenants, subject to certain exceptions, restricting or limiting the Company’s and its 
subsidiaries’ ability to, among other things: (i) make non-ordinary course dispositions of assets; (ii) make certain fundamental 
business changes, such as mergers, consolidations or any similar combination; (iii) make restricted payments, including 
dividends and stock repurchases; (iv) incur indebtedness; (v) make certain loans and investments; (vi) create liens; (vii) transact 
with affiliates; (viii) enter into certain sale/leaseback transactions; (ix) make negative pledges; and (x) modify subordinated debt 
documents. 

Under the 2022 Credit Agreement, restricted payments, including dividends and stock repurchases, shall be permitted if (i) the 
Company’s leverage ratio is less than or equal to 3.25x; (ii) the Company is in compliance with all other financial covenants; 
and (iii) there are no existing defaults under the 2022 Credit Agreement. If its leverage ratio is more than 3.25x, the Company is 
still permitted to fund (1) up to $35 million of dividend payments and stock repurchases annually; and (2) additional 
incremental other cash payments up to the greater of $65 million or 5% of consolidated total assets for the term of the 2022 
Credit Agreement.

FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

The 2022 Credit Agreement contains customary events of default. If an event of default occurs and is continuing, the Borrowers 
may be required immediately to repay all amounts outstanding under the 2022 Credit Agreement and the commitments from the 
lenders may be terminated.

The 2022 Credit Agreement amended and restated the Second Amended and Restated Credit Agreement (as amended, the
“2019 Credit Agreement”), which provided the Company with a $500 million revolving credit facility. 

In connection with entering into the 2022 Credit Agreement during the year ended December 31, 2022, the Company wrote off 
$0.1 million of unamortized deferred financing fees associated with the 2019 Credit Agreement, and incurred $1.9 million of 
new debt issuance costs. The new fees have been deferred and are being amortized over the five-year term as a component of 
Interest expense, net on the Consolidated Statements of Operations.  

As of December 31, 2023, there was $173.2 million of cash drawn on the Revolver, $124.2 million outstanding under the term 
loan facility and $9.1 million of undrawn letters of credit under the 2022 Credit Agreement, with $492.7 million of net 
availability for borrowings.

$10.2 million in 2026 and $276.3 million in 2027. The weighted average interest rate on long-term borrowings was 5.9% at 
December 31, 2023.

The Company paid interest of $22.8 million in 2023, $9.4 million in 2022 and $3.9 million in 2021.

Interest Rate Swap

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.   

On July 11, 2023, the Company entered into an additional interest rate swap (the “2023 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 2023 Swap is 
designated as a cash flow hedge, with an original maturity date of August 1, 2025. 

As a result of the application of hedge accounting treatment, all unrealized gains and losses related to the derivative instruments 
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.

The fair value of the Company’s interest rate swaps is derived from a discounted cash flow analysis based on the terms of the 
contract and the interest rate curve (Level 2 inputs) and measured on a recurring basis in our Consolidated Balance Sheets. 

At December 31, 2023 and 2022, the fair value of the Company’s interest rate swaps was a liability of $0.7 million and $0.3 
million, respectively, and are included in Other long-term liabilities on the Consolidated Balance Sheets. During the year ended 
December 31, 2023, an unrealized pre-tax loss of $0.4 million was recorded in Accumulated other comprehensive loss, whereas 
during the years ended December 31, 2022 and 2021, unrealized pre-tax gains of $4.1 million and $2.3 million, respectively, 
were recorded in Accumulated other comprehensive loss. No ineffectiveness was recorded in any of the periods presented.

In connection with entering into the 2022 Credit Agreement in October 2022, the Company terminated an interest rate swap 
initially entered into in 2019, receiving proceeds of $4.3 million upon settlement. The settlement gain was recorded in 
Accumulated other comprehensive loss and is being amortized into earnings ratably through the original maturity date of July 
30, 2024 as a component of Interest expense, net on the Consolidated Statements of Operations. During the years ended 
December 31, 2023 and 2022, the Company recognized non-cash settlement gains of $2.4 million and $0.5 million, 
respectively, as a component of Interest expense, net on the Consolidated Statements of Operations. At December 31, 2023 and

The Company recognized income tax expense of $45.6 million for the year ended December 31, 2023, compared to $30.5 
million for the year ended December 31, 2022. The increase in income tax expense in the current year was primarily due to 
higher earnings and the non-recurrence of certain discrete tax benefits recognized in the prior year associated with the release of 
valuation allowances, partially offset by a $1.5 million increase in the amount of excess tax benefits from stock compensation 
activity compared to the prior year. In the year ended December 31, 2022, the Company recognized a $2.6 million tax benefit 
from the release of a valuation allowance that had previously been recorded against deferred tax assets associated with foreign 
tax credits in the U.S., primarily due to tax planning. The Company also recognized a $1.1 million tax benefit during the year 
ended December 31, 2022 associated with the release of a valuation allowance in the U.K., as the associated deferred tax assets

were considered more-likely-than-not to be realized primarily due to increased projections of future taxable income. Including 
these items, the Company’s effective tax rate for the year ended December 31, 2023 was 22.5%, compared to 20.2% in 2022. 

The Company recognized income tax expense of $30.5 million for the year ended December 31, 2022, compared to $17.0 
million for the year ended December 31, 2021. The increase in income tax expense in 2022 was primarily due to higher 
earnings, a $3.2 million reduction in the amount of excess tax benefits from stock compensation activity compared to 2021, and 
fewer discrete tax benefits than in 2021. In the year ended December 31, 2022, the Company recognized a $2.6 million tax 
benefit from the release of a valuation allowance that had previously been recorded against deferred tax assets associated with 
foreign tax credits in the U.S., and also recognized a $1.1 million tax benefit associated with the release of a valuation 
allowance in the U.K. In the year ended December 31, 2021, the Company recognized a $3.4 million tax benefit associated with 
the release of state valuation allowances and a $3.3 million tax benefit associated with the remeasurement of deferred taxes for 
changes in state tax apportionment, both of which primarily resulted from a change in tax status and other tax planning 
activities executed during the year. Including these items, the Company’s effective tax rate for the year ended December 31, 
2022 was 20.2%, compared to 14.5% in 2021.

The Company paid income taxes of $46.2 million in 2023, $26.9 million in 2022 and $35.5 million in 2021.

The deferred tax asset for net operating loss and tax credit carryforwards at December 31, 2023 includes state net operating loss 
carryforwards of $4.5 million, which will begin to expire in 2024, and foreign net operating loss carryforwards of $9.5 million, 
which have an indefinite carryforward period. 

The deferred tax asset for tax loss and tax credit carryforwards at December 31, 2022, included state net operating loss 
carryforwards of $5.4 million, state income tax credits of $0.3 million, foreign net operating loss carryforwards of $9.7 million, 
and U.S. foreign tax credits of $2.6 million.

The $75.5 million of deferred tax assets at December 31, 2023, for which no valuation allowance is recorded, is anticipated to 
be realized through future taxable income or the future reversal of existing taxable temporary differences recorded as deferred 
tax liabilities at December 31, 2023. Should the Company determine that it is not more-likely-than-not to be able to realize its 
remaining deferred tax assets in the future, an adjustment to the valuation allowance would be recorded in the period such 
determination is made.

Generally, the Company has considered cash and cash equivalents held by subsidiaries outside the U.S. to be indefinitely 
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. As of December 31, 2023, the Company continues to assert that its undistributed earnings of certain foreign 
subsidiaries are indefinitely reinvested. It is not practicable to determine the income tax liability that would be payable if such 
earnings were not permanently reinvested.

Valuation Allowances

ASC 740, Income Taxes, requires that the future realization of deferred tax assets depends on the existence of sufficient taxable 
income in future periods. Possible sources of taxable income include taxable income in carryback periods, the future reversal of 
existing taxable temporary differences recorded as a deferred tax liability, tax-planning strategies that generate future income or 
gains in excess of anticipated losses in the carryforward period and projected future taxable income. If, based upon all available 
evidence, both positive and negative, it is more likely than not such deferred tax assets will not be realized, a valuation 
allowance is recorded. Significant weight is given to positive and negative evidence that is objectively verifiable. A company’s 
three-year cumulative loss position is significant negative evidence in considering whether deferred tax assets are realizable and 
the accounting guidance restricts the amount of reliance the Company can place on projected taxable income to support the 
recovery of the deferred tax assets.

We continually evaluate the need to maintain a valuation allowance for deferred tax assets based on our assessment of whether 
it is more likely than not that deferred tax benefits will be realized through the generation of future taxable income. Appropriate 
consideration is given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. 

As of December 31, 2023, the Company’s valuation allowance was $0.5 million, which represents the estimated amount of state 
net operating loss carryforwards that are not more-likely-than not to be realized prior to expiration. During the year ended 
December 31, 2023, the Company’s valuation allowance decreased by $0.2 million, primarily due to increased projections of 
future taxable income associated with these state net operating loss carryforwards.

During the year ended December 31, 2023, the Company filed amended U.S. federal income tax returns for the 2015 through 
2018 tax years to claim a worthless stock deduction. As of December 31, 2023, the aggregate refund claim associated with the 
worthless stock deduction was $13.6 million, including interest of $1.8 million which is not included in the table above. As 
recovery of the refund claim was not considered more-likely-than-not as of December 31, 2023, the Company recognized an 
offsetting increase to its liability for unrecognized tax benefits. In accordance with ASC 740, the Company has recorded a 
receivable for the full amount of the refund claim, including interest, and an offsetting liability for unrecognized tax benefits for 
the same amount. The receivable and offsetting liability have been presented net on the Consolidated Balance Sheets and, as the 
refund claim is fully reserved, the recognition of the uncertain tax position had no impact on the Consolidated Statements of 
Operations during the year ended December 31, 2023. As of December 31, 2023, the amended tax returns were under 
examination by the applicable tax authorities. Subsequent to December 31, 2023, the tax authorities notified the Company that 
the amended tax returns had been approved, at which point receipt of the refund claim was considered more-likely-than-not. As 
a result, the Company expects to record a corresponding reduction in unrecognized tax benefits during the first quarter of 2024, 
which would impact the Company’s effective tax rate in 2024.       

The Company’s accounting policy is to recognize interest and penalties related to income tax matters in income tax expense. At 
both December 31, 2023 and 2022, accruals for interest and penalties amounting to $0.4 million, were included in the 
Consolidated Balance Sheets but are not included in the table above. At December 31, 2023 and 2022, liabilities for 
unrecognized tax benefits, including interest and penalties of $1.1 million and $1.6 million, respectively, were included within 
Other long-term liabilities on the Consolidated Balance Sheets and would impact the Company’s effective rate, if recognized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

Other than the anticipated reduction in unrecognized tax benefits associated with the approval of the amended tax returns 
previously described, the Company does not expect significant changes to its unrecognized tax benefits as a result of potential 
expiration of statute of limitations or settlements with the tax authorities within the next twelve months.

Status of Tax Returns

We file U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2020 through 2022 
tax years generally remain subject to examination by federal tax authorities, whereas the 2019 through 2022 tax years generally 
remain subject to examination by most state tax authorities. In significant foreign jurisdictions, the tax years from 2019 through 
2022 generally remain subject to examination by their respective tax authorities.

NOTE 11 — PENSION AND OTHER POST-EMPLOYMENT PLANS 

Defined Benefit Pension Plans

The Company and its subsidiaries sponsor two defined benefit pension plans covering certain salaried and hourly employees. 
These plans have been closed to new participants for a number of years. Benefits under these plans are primarily based on final 
average compensation and years of service as defined within the provisions of the individual plans. As a result of plan 
amendments, the latest of which was in 2008, the only new benefits that were being accrued through the end of 2016 were 
salary increases for a limited group of participants. Those benefits ceased at the end of 2016, at which point all existing plans 
became fully frozen.

On November 5, 2021, the Company purchased a group annuity contract from an insurance company, under which 
approximately $25 million of the projected benefit obligation of the U.S. benefit plan was transferred to the insurance company. 
In this transaction, the insurance company assumed responsibility for pension benefits and administration for approximately 
800 retirees or their beneficiaries. The transaction was funded on November 15, 2021 with existing assets of the U.S. benefit 
plan. As a result, the Company recognized a pension settlement charge of $10.3 million in the year ended December 31, 2021.

As more fully described within Note 18 – Fair Value Measurements, the Company uses a three-level fair value hierarchy that 
prioritizes the inputs used to measure fair value. 

Following is a description of the valuation methodologies used for assets measured at fair value for the U.S. benefit plan:

•

•

•

Cash and cash equivalents are comprised of cash on deposit and a money market fund, that invests principally in short-
term instruments. The money-market fund is valued at the net asset value (“NAV”) of the shares in the fund.
Equity investments represent domestic and foreign securities, including common stock, which are publicly traded on 
active exchanges and are valued based on quoted market prices. Certain equity securities, which are valued using a 
model that takes the underlying security’s “best” price, divides it by the applicable exchange rate and multiplies the 
result by a depository receipt factor, are categorized within Level 2 of the fair value hierarchy.
Fixed income investments include corporate bonds, asset-backed securities and treasury bonds. Corporate bonds are 
valued using pricing models that include bids provided by brokers or dealers, benchmark yields, base spreads and 
reported trades. Asset-backed securities are valued using models with readily observable data as inputs. Treasury 
bonds are valued based on quoted market prices in active markets.

Following is a description of the valuation methodologies used for assets measured at fair value for the non-U.S. benefit plan:

•

•

•

Cash and cash equivalents are comprised of cash on deposit and a money market fund, that invests principally in short-
term instruments. The money-market fund is valued at the NAV of the shares in the fund.
Diversified investment funds and insurance-linked securities are valued based on a daily NAV per share measured by 
the fund sponsor and used as the basis for current transactions. 
Fixed income investments include corporate bonds and asset-backed securities. Corporate bonds are valued based on 
quoted market prices in active markets or other readily observable market data. Asset-backed securities are valued 
using models with readily observable data as inputs.

The methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of 
future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other 
market participants, the use of different methodologies or assumptions to determine the fair value of certain financial 
instruments could result in a different fair value measurement at the reporting date.

The Company maintains a structured investment strategy for its U.S. and non-U.S. benefit plans, which are designed to achieve 
certain target asset allocations depending on the plans’ relative funded status. 

As of December 31, 2023, the target asset allocations for the U.S. benefit plan are (i) between 54% and 69% in fixed income 
investments, (ii) between 29% and 44% in equity investments and (iii) between 0% and 20% in cash and cash equivalents.

As of December 31, 2023, the target asset allocations for the non-U.S. benefit plan assets are generally between 65% and 75% 
in fixed income investments and cash and cash equivalents, and between 25% and 35% in equity investments.

As the Company’s benefit plans are fully frozen, all plan participants are now considered to be inactive. As a result, the 
associated actuarial losses and prior service costs that are included in Accumulated other comprehensive loss are being 
amortized into net periodic benefit cost over the remaining average life expectancy of plan participants. The Company expects 
$2.9 million of the actuarial losses and $0.1 million of the prior service costs to be amortized from Accumulated other 
comprehensive loss into net periodic benefit cost in 2024. 

The Company currently expects to contribute up to $5.0 million to the U.S. benefit plan and up to $0.2 million to the non-
U.S. benefit plan in 2024. Future contributions to the plans will be based on such factors as annual service cost, the financial 
return on plan assets, interest rate movements that affect discount rates applied to plan liabilities and the value of benefit 
payments made.

The following summarizes the benefits expected to be paid under the Company’s benefit plans in each of the next five years, 
and in aggregate for the five years thereafter:

Defined Contribution Retirement Plan

The Company also sponsors a defined contribution retirement plan (the “401(k) plan”) covering a majority of its employees. 
Participation is via automatic enrollment and employees may elect to opt out of the 401(k) plan. Company contributions to the 
401(k) plan are based on an employee’s years of service, as well as the percentage of employee contributions. The Company’s 
cost of the 401(k) plan was $11.4 million in 2023, $9.9 million in 2022 and $8.9 million in 2021.

Deferred Compensation Plan

The Company also provides a deferred compensation plan to certain employees. The deferred compensation plan is a non-
qualified, unfunded defined contribution plan, which provides participants with benefits that would have been provided under 
the 401(k) plan, but could not be provided due to compensation limits for qualified plans under the Internal Revenue Code. At 
December 31, 2023 and 2022, deferred compensation liabilities of $19.9 million and $15.3 million, respectively, were included 
on the Consolidated Balance Sheets, primarily within Long-term pension and other post-retirement benefit liabilities.

NOTE 12 — 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 December 31, 
2023, the Company had outstanding performance and financial standby letters of credit, as well as outstanding bid and 
performance bonds, aggregating to $21.2 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 December 31, 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 $1.5 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 December 31, 2023, the total amount of future payments 
guaranteed under these agreements was approximately $0.9 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:

NOTE 13 — 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 

64

 
 
 
 
 
FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

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 claiming that exposure to the Company’s sirens impaired 
their hearing and the sirens are therefore defective. Between 1999 and 2013, 40 cases were filed on behalf of a total of 2,816 
plaintiffs in the Circuit Court of Cook County, Illinois. 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. In 2009, a trial was held on behalf of nine 
Chicago firefighter plaintiffs and concluded with a verdict for the plaintiffs in varying amounts totaling $0.4 million. Following 
appeals, the Company satisfied the judgments, resulting in the final dismissal of the cases. A third consolidated trial involving 
eight Chicago firefighter plaintiffs occurred in November 2011. The jury returned a unanimous verdict in favor of the 
Company. Thereafter, the trial court scheduled a fourth consolidated trial involving three firefighter plaintiffs. Prior to trial, the 
claims of two of the firefighter plaintiffs were dismissed, and on December 17, 2012, the jury entered a complete defense 
verdict for the Company. On December 20, 2021, the parties executed a settlement agreement to resolve claims of 
approximately 462 firefighters still involved in the litigation, agreeing to pay a lump sum of $0.2 million based upon an 
assessment of firefighters who met minimal bilateral hearing loss standards. The estimated settlement amount was accrued by 
the Company. The settlement agreement did not require the payment of any attorney fees by the Company and provided that 
plaintiffs’ attorney would withdraw from representing firefighters who did not agree to the settlement. In July 2022, the 
Company issued the 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 
Illinois based on improper venue. On February 24, 2017, the Circuit Court of Cook County dismissed the cases of 1,770 such 
firefighter plaintiffs. In 2017, the Company entered into a global settlement agreement (the “2017 Settlement Agreement”) with 
two attorneys who represented approximately 1,090 of these plaintiffs offering to pay $700 per plaintiff to settle these cases, 
and 717 plaintiffs accepted this offer as a final settlement. The 2017 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 are barred from doing so by the statute of limitations. 

The Company was also sued on this issue outside of the Cook County, Illinois venue. Between 2007 and 2009, 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, one case was voluntarily dismissed, and others were settled for nominal sums. Three 
trials were held in these cases. In the first trial, a jury returned a verdict for the plaintiff, finding that the Company’s siren was 
not defectively designed but that the Company negligently constructed the siren. The jury awarded damages in an amount less 
than $0.1 million. In 2010, a jury returned a defense verdict for the Company as to the claims of nine plaintiffs. In a third trial, 
the jury returned a defense verdict for the Company as to the claims of nine plaintiffs. Following the defense verdicts in the last 
two Philadelphia trials, in order to avoid the inconvenience, uncertainty and distraction of the lawsuits, the Company entered 
into a global settlement agreement (the “2010 Settlement Agreement”) on behalf of 1,125 claimants (the “Claimants”). The 
2010 Settlement Agreement provided that the Company pay a total amount of $3.8 million 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 global settlement agreement. On April 22, 2011, the Company confirmed that the 
terms and conditions of the 2010 Settlement Agreement had been met and made an adjusted 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. 
The Company generally denies the allegations made in the lawsuits and denies that its products caused any injuries to the 
Claimants. 

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 which were dismissed prior to trial.

In 2012, 20 new cases were filed in Philadelphia on behalf of 20 Philadelphia firefighters against various defendants in addition 
to the Company. Five of these cases were dismissed. The first trial involving these cases occurred in December 2014 and 
involved three firefighter plaintiffs. The jury returned a verdict in favor of the Company. Following the trial, the parties agreed 
to settle cases involving seven firefighter plaintiffs for nominal amounts. 

In January 2015, plaintiffs’ attorneys filed two new complaints in Philadelphia on behalf of approximately 70 additional 
firefighter plaintiffs. One of the complaints, 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 that case on May 

65

FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

31, 2016. The Company thereafter moved to recover fees and costs in this case, asserting that plaintiffs’ counsel failed to 
properly investigate the claims prior to filing suit. The Court granted the motion, awarding $0.1 million to the Company, and 
the United States Court of Appeals for the Third Circuit affirmed the decision awarding fees and costs to the Company. The 
Court granted the Company’s motion to dismiss the remaining out-of-state firefighters. In 2015, another nine new cases 
involving a total of 193 firefighters were filed in Philadelphia. The court dismissed all claims filed by out-of-state firefighters, a 
decision affirmed by the appellate court. 

In 2016 and 2017, plaintiffs filed new cases involving a total of 155 Philadelphia firefighters in Philadelphia state court, and the 
cases were transferred to the mass tort program in Philadelphia for pretrial purposes. In November 2017, a trial involving one 
Philadelphia firefighter occurred, and the jury returned a verdict in favor of the Company. 

In 2014, an action was brought in the Court of Common Pleas of Erie County, Pennsylvania on behalf of 61 firefighters against 
various defendants in addition to the Company. Also in 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. In 2015, the Company was served with a 
complaint filed in Union County, New Jersey state court, involving 34 New Jersey firefighters. In 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. In 2017, plaintiffs’ attorneys filed additional hearing loss cases in Florida. Prior to a 
dismissal of these cases pursuant to the Tolling Agreement discussed below, there was a total of 1084 firefighters involved in 
these cases.

In 2013, cases were filed in Allegheny County, Pennsylvania on behalf of 247 plaintiff firefighters from Pittsburgh and against 
various defendants including the Company. In 2016, cases were filed against an additional 19 Pittsburgh firefighters. After the 
Company filed pretrial motions, the Court dismissed claims of 55 Pittsburgh firefighter plaintiffs. Prior to the first scheduled 
trial, 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. A jury 
rendered a verdict in favor of the Company in 2017. 

In 2017, five cases involving 70 firefighter plaintiffs were filed in Lackawanna County, Pennsylvania.

A second trial involving Pittsburgh firefighters began in 2018. At the outset of this trial, plaintiffs’ attorneys, who represent all 
firefighters who filed cases in Allegheny County, Philadelphia, Buffalo, New Jersey, Massachusetts, and Florida requested that 
the Company consider settlement of various cases. In 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 Cook County, Illinois and Lackawanna County, Pennsylvania and a case involving one firefighter in New York City, 
cases being handled by different attorneys. The Company later settled the cases in Lackawanna County and settled the case 
involving one firefighter in New York City for nominal amounts.

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 a global settlement agreement (the “2019 Settlement 
Agreement”) on November 4, 2019. After execution of the 2019 Settlement Agreement, the Allegheny County (Pittsburgh) 
cases were dismissed. 

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 and $300 to each firefighter who has not yet filed a case and is eligible to be part of the settlement. 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. The Settlement Framework was finalized in a global settlement 
agreement executed on November 4, 2019. The global settlement agreement requires plaintiffs’ attorneys to withdraw from 
representing firefighters who elect not to participate in the settlement and does not include the payment of any attorney fees by 
the Company. Pursuant to the 2019 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. 

As of December 31, 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.

NOTE 14 — 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 years ended December 31, 2023, 2022 and 2021 were 
insignificant and did not materially impact the calculation of basic or diluted EPS.

Basic EPS is computed by dividing income or loss available to common stockholders by the weighted average number of shares 
of common stock outstanding for the year. 

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 year. The dilutive effect of 
common stock equivalents is determined using the more dilutive of the two-class method or alternative methods. We use 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 years ended December 31, 2023, 2022 and 2021, options to purchase 0.1 million, 0.3 million and 0.2 million shares of 
the Company’s common stock, respectively, had an anti-dilutive effect on EPS, and accordingly, are excluded from the 
calculation of diluted EPS.

NOTE 15 — STOCK-BASED COMPENSATION

The Company’s stock compensation plan, approved by the Company’s stockholders and administered by the Compensation and 
Benefits Committee of the Board of Directors of the Company (the “CBC”), provides for the grant of incentive stock options, 
restricted stock and other stock-based awards or units to key employees and directors. The plan, as amended, authorizes the 
grant of up to 11.0 million shares or units through April 2030. At December 31, 2023, approximately 4.7 million shares were 
available for future issuance under the plan. 

The total compensation expense related to all grants awarded under the plan was $13.1 million, $10.2 million and $7.6 million, 
for the years ended December 31, 2023, 2022 and 2021, respectively. The related income tax benefits recognized in earnings 
were $2.0 million, $1.9 million and $1.5 million for the years ended December 31, 2023, 2022 and 2021, respectively. 

Stock Options

Stock options vest ratably (i.e. one-third annually) over the three years from the date of the grant. The cost of stock options, 
based on their fair value at the date of grant, is charged to expense over the respective vesting periods. Stock options normally 
become exercisable at a rate of one-third annually and in full on the third anniversary date. Under the plan, all options and 
rights must be exercised within ten years from date of grant. At the Company’s discretion, vested stock option holders are 
permitted to elect an alternative settlement method in lieu of purchasing common stock at the option price. The alternative 
settlement method permits the employee to receive, without payment to the Company, cash, shares of common stock or a 
combination thereof equal to the excess of market value of common stock over the option purchase price. The Company 

67

 
 
 
 
 
 
 
 
 
 
 
 
FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

hashistorically settled all such options in common stock and intends to continue to do so. Stock options do not have voting or 
dividend rights until such time that the options are exercised and shares have been issued.

The weighted average fair value of options granted during 2023, 2022 and 2021 was $17.44, $12.64 and $13.54, respectively.

The fair value of each option grant was estimated using the Black-Scholes option pricing model with the following weighted 
average assumptions:

2023

2021

Expected dividend yield   ....................................................................................................

Dividend yields are based on historical dividend payments. Expected volatility is based on historical volatility of the 
Company’s common stock. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant 
for periods corresponding with the expected life of the options. The expected life of options represents the weighted average 
period of time that options granted are expected to be outstanding giving consideration to vesting schedules and the Company’s 
historical exercise patterns.

At December 31, 2023, options that have vested and are expected to vest totaled 1.0 million shares, with a weighted average 
exercise price of $31.53, and represent the sum of 0.7 million vested (or exercisable) options and 0.3 million options that are 
expected to vest. Options that are expected to vest are derived by applying the pre-vesting forfeiture rate assumption against 
outstanding, unvested options as of December 31, 2023.

for the years ended December 31, 2023, 2022 and 2021, respectively. As of December 31, 2023, there was $3.1 million of total 
unrecognized compensation cost related to stock options that is expected to be recognized over the weighted-average period of 
approximately 1.9 years. 

Restricted Stock

Restricted stock awards and restricted stock units primarily cliff vest at the third anniversary from the date of grant, provided 
the recipient is still employed by the Company on the vesting date. The cost of restricted stock, based on the fair market value 
of the underlying shares determined using the closing market price on the date of grant, is charged to expense over the 
respective vesting periods. Shares associated with non-vested restricted stock awards have the same voting rights as the 
Company’s common stock and have non-forfeitable rights to dividends. Shares associated with non-vested restricted stock units 
do not have voting or dividend rights.

The total grant-date fair value of restricted stock that vested in the years ended December 31, 2023, 2022 and 2021 was $3.5 
million, $2.1 million and $1.9 million, respectively. 

The total compensation expense related to all restricted stock compensation plans was $4.3 million, $3.8 million and $2.6 
million for the years ended December 31, 2023, 2022 and 2021, respectively. As of December 31, 2023, there was $3.6 million 
of total unrecognized compensation cost related to restricted stock that is expected to be recognized over the weighted-average 
period of approximately 1.8 years.

Performance Awards

In each of the three years in the period ended December 31, 2023, the Company granted performance-based restricted stock unit 
awards (“PSUs”) to certain executives and other non-executive officers. Performance targets associated with PSUs are set 
annually and approved by the CBC. At the Company’s discretion, actual payment of the awards earned shall be in cash or in 
common stock of the Company, or in a combination of both. The Company intends to settle all such awards by issuing shares of 
its common stock. Shares associated with non-vested PSUs do not have voting or dividend rights until issuance. The Company 
assesses the probability of vesting, based on expected achievement against these performance targets, on a quarterly basis. 

The PSUs granted in 2023 have a three-year performance period ending December 31, 2025, in which the Company must 
achieve a certain cumulative EPS and a certain average return on invested capital (“ROIC”), which are performance conditions 
per ASC 718, Compensation — Stock Compensation (“ASC 718”). The percentage of shares earned under these two 
performance conditions may be subject to a further 20% modifier, for a maximum potential payout of 240% of target, 
determined by comparing the Company’s total stockholder return (“TSR”) over a multi-year performance period, relative to that 
of the S&P 600 Capital Goods Index. The TSR modifier, which is a market condition under ASC 718, will only apply if the 
Company’s TSR performance over the performance period is in the top or bottom quartile of the S&P 600 Capital Goods Index. 
If earned, these shares would vest on December 31, 2025. 

The PSUs granted in 2022 have a three-year performance period ending December 31, 2024, in which the Company must 
achieve a certain cumulative EPS and a certain average ROIC, which are performance conditions per ASC 718. The percentage 
of shares earned under these two performance conditions may be subject to a further 20% modifier, for a maximum potential 
payout of 240% of target, determined by comparing the Company’s TSR over a multi-year performance period, relative to that 
of the S&P 600 Capital Goods Index. The TSR modifier, which is a market condition under ASC 718, will only apply if the 
Company’s TSR performance over the performance period is in the top or bottom quartile of the S&P 600 Capital Goods Index. 
If earned, these shares would vest on December 31, 2024.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

The PSUs granted in 2021 had a three-year performance period ending December 31, 2023, in which a certain cumulative EPS 
and a certain average ROIC was targeted. The number of shares of common stock that the Company may issue in connection 
with the PSUs granted in 2021 can range from 0% to 200% of target. The PSUs granted in 2021 became fully vested on 
December 31, 2023. Based on the achievement against targets over the three-year performance period, 132% of the target 
shares were earned. The underlying shares will be issued to participants in the first quarter of 2024. 

The cost of PSUs, based on their fair value, is charged to expense over the respective vesting periods, which is the three-year 
period ended December 31, 2023 for the 2021 grants, the three-year period ended December 31, 2024 for the 2022 grants and 
the three-year period ended December 31, 2025 for the 2023 grants. The fair value of the PSUs granted in 2021 was determined 
using the closing market price on the date of grant. As the PSUs granted in 2023 and 2022 contain a market condition, the 
Company utilized a Monte Carlo simulation model to determine the respective grant date fair values, using the following

FEDERAL SIGNAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (CONTINUED)

Products are sold to both municipal and industrial customers either through a dealer network or direct sales to service customers 
generally depending on the type and geographic location of the customer. In addition to vehicle and equipment sales, the Group 
also engages in the sale of parts, service and repair, equipment rentals and training as part of a comprehensive aftermarket 
offering to its current and potential customers through its service centers located across North America. Our Environmental 
Solutions Group includes the aggregated results of two operating segments, including TBEI.

In addition, as discussed in Note 2 – Acquisitions, the Company completed the acquisitions of substantially all of the assets and 
operations of Trackless and Blasters during the year ended December 31, 2023. The assets and liabilities of Trackless and 
Blasters have been consolidated into the Consolidated Balance Sheet as of December 31, 2023, while the post-acquisition 
results of operations of Trackless and Blasters have been included in the Consolidated Statements of Operations subsequent to 
their respective closing dates, within the Environmental Solutions Group.

Safety and Security Systems — Our Safety and Security Systems Group is a leading manufacturer and supplier of 
comprehensive systems and products that law enforcement, fire rescue, emergency medical services, campuses, military

Group operates manufacturing facilities in the U.S., Spain, the U.K., and South Africa.

Corporate contains those items that are not included in our reportable segments.

Net sales by reportable segment reflect sales of products and services to external customers, as reported in the Company’s 
Consolidated Statements of Operations. Intersegment sales are insignificant. The Company evaluates performance based on 
operating income of the respective segment. Operating income includes all revenues, costs and expenses directly related to the 
segment involved. In determining reportable segment income, neither corporate nor interest expenses are included. Reportable 
segment depreciation and amortization expense, identifiable assets and capital expenditures relate to those assets that are 
utilized by the respective reportable segment. Corporate assets consist principally of cash and cash equivalents, deferred tax 
assets and fixed assets. The accounting policies of each reportable segment are the same as those described in Note 1 – 
Summary of Significant Accounting Policies.

Revenues attributed to customers located outside of the U.S. aggregated to $385.3 million in 2023, $285.0 million in 2022 and 
$286.4 million in 2021, of which sales exported from the U.S. aggregated to $136.0 million, $88.8 million and $77.0 million, 
respectively.

NOTE 18 — 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 9 – 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

As of December 31, 2023, the Company had contingent obligations to transfer up to $7.5 million, $8.0 million, and C$6.0 
million (approximately $4.5 million), to the former owners of Deist, Blasters, and Trackless, respectively, if specified financial 
results are met over future reporting periods (i.e., an earn-out). The Deist, Blasters, and Trackless acquisitions were completed 
on December 30, 2021, January 3, 2023, and April 3, 2023, respectively. The Deist and Trackless contingent earn-out 
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 be paid annually, in each of the three years following the anniversary of the closing 
date. During the year ended December 31, 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), net on the Consolidated Statements of Operations. 

The Company uses an income approach to value the contingent consideration obligation based on the present value of risk-

Item 9A. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

The Company carried out an evaluation, under the supervision and with the participation of its management, including the Chief 
Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s “disclosure 
controls and procedures” (as defined in the Exchange Act Rule 13a-15(e)) as of December 31, 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 December 31, 2023.

(b) Management’s Annual Report on Internal Control over Financial Reporting and Attestation Report of the 

Registered Public Accounting Firm

The Company’s management is responsible for establishing and maintaining an adequate system of internal control over 
financial reporting, as defined in Exchange Act Rule 13a-15(f). Management conducted an assessment of the Company’s 
internal control over financial reporting based on the framework established by the Committee of Sponsoring Organizations of 
the Treadway Commission in Internal Control — Integrated Framework (2013). Based on the assessment, management 
concluded that, as of December 31, 2023, the Company’s internal control over financial reporting is effective.

During the year ended December 31, 2023, the Company completed the acquisition of substantially all the assets and operations 
of Trackless, as discussed in Note 2 – Acquisitions to the accompanying consolidated financial statements. Management has 
excluded Trackless from its assessment of the Company’s internal controls over financial reporting as of December 31, 2023. 
Trackless’ net sales and total assets (excluding goodwill and intangible assets, which were integrated into the Company’s 
control environment) represent approximately 1% and 2%, respectively, of the consolidated financial statement amounts as of, 
and for the year ended, December 31, 2023.

Deloitte & Touche LLP, an independent registered public accounting firm, has audited the consolidated financial statements 
included in this Annual Report on Form 10-K and, as part of their audit, has issued its report, included herein, on the 
effectiveness of the Company’s internal control over financial reporting. See “Report of Independent Registered Public 
Accounting Firm” under Item 8 of Part II of this Form 10-K.

(c) Changes in Internal Control over Financial Reporting

From time to time, the Company may make changes aimed at enhancing the effectiveness of the controls and to ensure that the 
systems evolve with the business. There were no changes in the Company’s internal control over financial reporting that 
occurred during the Company’s most recently completed fiscal quarter that have materially affected, or are reasonably likely to 
materially affect, the Company’s internal control over financial reporting.

Item 9B.  Other Information.

On February 27, 2024, the Company issued a press release announcing its financial results for the three months and year ended 
December 31, 2023. The presentation slides for the 2023 fourth quarter earnings call were also posted on the Company’s
