Federal Signal Corporation (FSS) is a leading global manufacturer and supplier of specialized vehicles, equipment, and safety solutions for municipal, governmental, industrial, and commercial customers. The company has a long and storied history, dating back to its founding in 1901, and has since evolved into a diversified industrial conglomerate with a strong focus on environmental and safety-oriented products and services.
Business Overview
Federal Signal Corporation was founded in 1901 and 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. Federal Signal's portfolio includes vehicles and equipment for maintenance and infrastructure end-markets, as well as public safety equipment such as vehicle lightbars and sirens.
The company operates 23 principal manufacturing facilities in five countries and provides products and integrated solutions globally. Federal Signal's business units are organized into two reportable segments - the Environmental Solutions Group and the Safety and Security Systems Group. These groups share certain characteristics, including technology, marketing, distribution, and product application, which create long-term synergies.
Over its more than 120-year history, Federal Signal has faced various challenges. In the late 1990s and early 2000s, the company was sued by multiple firefighters claiming that exposure to its sirens impaired their hearing. Federal Signal vigorously defended itself against these claims, obtaining many jury verdicts in its favor and settling some for nominal amounts. In 2018, the company reached a global settlement agreement to pay a specified amount to each eligible firefighter.
Despite this litigation, Federal Signal continued to invest in new product development and strategic acquisitions to diversify its customer base, penetrate new end-markets, and gain access to new geographic regions. For example, the company completed 12 acquisitions between 2016 and 2023, including the purchases of Trackless Vehicles, Blasters, and Standard Equipment Company. These acquisitions bolstered Federal Signal's position as an industry-leading diversified industrial manufacturer of specialized vehicles and equipment.
The Environmental Solutions Group is the larger of the two, accounting for approximately 84% of the company's total revenue in 2024. This segment is a leading manufacturer and supplier of a full range of specialized vehicles and equipment for maintenance and infrastructure end-markets. The Safety and Security Systems Group, on the other hand, is a leading manufacturer and supplier of comprehensive systems and products used by law enforcement, fire rescue, emergency medical services, campuses, military facilities, and industrial sites to protect people and property.
Financials
Financial Performance
Federal Signal has delivered exceptional financial performance in recent years, consistently growing its top and bottom lines. In 2024, the company reported record net sales of $1.86 billion, an 8% increase from the prior year. This growth was driven by strong demand across both of its reportable segments, with the Environmental Solutions Group and the Safety and Security Systems Group reporting sales increases of 8% and 7%, respectively.
The company's profitability has also been impressive, with operating income increasing by 25% in 2024 to $281.4 million. This translated to an operating margin of 15.1%, up from 13.0% in the prior year. Adjusted EBITDA, a key metric for the company, rose 23% to $350.6 million, with the adjusted EBITDA margin expanding by 220 basis points to 18.8%.
For the full year 2024, Federal Signal reported net income of $216.3 million, GAAP diluted EPS of $3.50 per share (up 37% from the prior year), and adjusted EPS of $3.34 per share (up 29% from the prior year). The company's performance in the fourth quarter of 2024 was particularly strong, with quarterly revenue of $472 million (a 5% year-over-year increase), quarterly net income of $50 million (an 8% increase), and quarterly operating cash flow of $91 million (an 18% increase).
Liquidity
Federal Signal's strong financial performance has enabled the company to generate significant cash flow, with operating cash flow totaling $231 million in 2024, a 19% increase from the prior year. Free cash flow for the year was $190.7 million. This robust cash generation has provided the company with the resources to fund organic growth initiatives, pursue strategic acquisitions, and return capital to shareholders through dividends and share repurchases.
As of December 31, 2024, Federal Signal had a solid financial position with $91.1 million in cash and cash equivalents, and $574.3 million of net availability under its $800 million revolving credit facility. The company's debt-to-equity ratio stood at 0.21, while its current ratio was 2.66 and its quick ratio was 1.29, indicating strong liquidity and financial flexibility.
Acquisition Strategy
A key driver of Federal Signal's growth has been its disciplined approach to mergers and acquisitions. Since 2016, the company has completed 12 acquisitions, including the recent purchase of HOG Technologies, a leading manufacturer of truck-mounted road-marking, line-removal, and waterblasting equipment.
The acquisition of HOG Technologies, which was completed in February 2025, is expected to be accretive to Federal Signal's earnings and cash flow. The deal not only expands the company's product portfolio and end-market exposure but also provides opportunities for synergies in areas such as channel alignment, cross-selling, procurement savings, and aftermarket parts and service expansion.
This acquisition strategy has allowed Federal Signal to diversify its revenue streams, enhance its technological capabilities, and strengthen its position as a leading provider of specialized vehicles and equipment for the maintenance and infrastructure markets. The company's successful integration of these acquired businesses has been a key factor in its ability to consistently outperform its peers and the broader market.
Segment Performance
Environmental Solutions Group
The Environmental Solutions Group is Federal Signal's largest segment, accounting for approximately 84% of the company's total revenue in 2024. This group is a leading manufacturer and supplier of a comprehensive range of specialized vehicles and equipment for maintenance and infrastructure markets. Its product portfolio includes 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 maintenance vehicles.
In 2024, the Environmental Solutions Group reported net sales of $1.56 billion, an increase of $119.2 million or 8% compared to the prior year. This growth was driven by higher sales volumes, including contributions from recent acquisitions, as well as the implementation of pricing actions.

Orders for the Environmental Solutions Group in 2024 totaled $1.54 billion, a decrease of $36.4 million or 2% from the prior year, including the impact of lower chassis orders. The group's backlog stood at $939.7 million as of December 31, 2024, a decrease of $26.8 million compared to the prior year-end.
Safety and Security Systems Group
The Safety and Security Systems Group is Federal Signal's second reportable segment, focusing on the manufacture and supply of comprehensive systems and products used by law enforcement, fire rescue, emergency medical services, campuses, military facilities, and industrial sites to protect people and property. The group's product offerings include public safety equipment such as vehicle lightbars and sirens, industrial signaling equipment, public warning systems, and general alarm/public address systems.

Geographic Performance
Federal Signal has a strong presence in the United States, which accounted for approximately 79% of its net sales in 2024. The company also has international operations, with approximately 21% of its net sales coming from customers outside the U.S. in the same year. This geographic diversification helps to mitigate risks associated with regional economic fluctuations and provides opportunities for growth in emerging markets.
Outlook and Risks
Looking ahead, Federal Signal remains well-positioned for continued growth. The company's strong backlog, which stood at $997 million as of the end of 2024, provides excellent visibility into the first half of 2026. For the full year 2025, Federal Signal is guiding for net sales between $2.02 billion and $2.10 billion, representing double-digit growth from the prior year. The company also expects double-digit improvement in pretax earnings, EBITDA margins in the upper half of their 17% to 22% target range, and adjusted EPS between $3.60 and $3.90 per share, which would represent another year of double-digit growth and the highest adjusted EPS level in the company's history.
For the first quarter of 2025, Federal Signal expects earnings to represent 19% to 20% of the full-year earnings, similar to the prior year. Capital expenditures are projected to be between $40 million and $50 million for 2025.
However, the company is not without its risks. Federal Signal operates in a highly competitive industry and is subject to macroeconomic factors that can impact demand for its products, such as fluctuations in municipal and industrial spending. The company is also exposed to supply chain disruptions and the risk of rising material and labor costs, which could put pressure on its profit margins.
Additionally, the company's acquisition strategy carries inherent risks, such as the potential for integration challenges, the inability to fully realize expected synergies, and the possibility of overpaying for target companies. Federal Signal mitigates these risks through its thorough due diligence process and its experience in successfully integrating acquisitions.
Human Capital and Labor Risks
As of December 31, 2024, Federal Signal employed approximately 4,700 people globally, with about 55% being U.S. hourly workers. Of these U.S. hourly workers, 10% were represented by unions. The company has experienced challenges with labor availability in certain markets, which has contributed to extended lead times for some products. To address these issues, Federal Signal continues to focus on employee attraction, development, and retention initiatives.
Industry Trends
The markets in which Federal Signal operates, including municipal, governmental, industrial, and commercial end-markets, have historically been subject to fluctuations based on economic conditions and government spending. However, the essential nature of Federal Signal's products and the company's diversification efforts, including growth in its aftermarket business, have helped to mitigate cyclicality. The industry is estimated to have a compound annual growth rate (CAGR) of low to mid single digits over the next 5 years, providing a stable foundation for Federal Signal's continued growth.
Conclusion
Federal Signal Corporation has established itself as a serial acquirer, successfully executing a growth strategy that has allowed the company to consistently outperform its peers and the broader market. With its diversified product portfolio, strong financial performance, and disciplined approach to mergers and acquisitions, Federal Signal is well-positioned to continue delivering exceptional results for its shareholders. The company's record performance in 2024 and positive outlook for 2025 demonstrate its ability to navigate challenges and capitalize on opportunities in its target markets. As Federal Signal continues to execute its strategic initiatives and leverage its strong market position, it remains an attractive investment option for those seeking exposure to the industrial manufacturing sector.
