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 should be read together with, the condensed consolidated financial statements and the accompanying notes contained in this Form 10-Q, as well as the Company's Annual Report on Form 10-K for the year ended December 31, 2024. Information in MD&A is intended to provide an analysis of our financial condition and results of operations from management's perspective and assist the reader in obtaining an understanding of (i) the condensed 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 condensed consolidated financial statements, and to provide discussion of material events and uncertainties known to management that are reasonably likely to cause reported financial information not to be indicative of future operating results or future financial condition. The Company's results for interim periods should not be regarded as necessarily indicative of results that may be expected for the entire year, which may differ materially due to, among other things, the risk factors described under Part I, Item 1A, Risk Factors, of the Company's Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on February 26, 2025.
    
    
      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, 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 maintenance vehicles, and (ii) public safety equipment, such as vehicle lightbars and sirens, industrial signaling equipment, public warning systems, and general alarm/public address systems. Product offerings also include certain products manufactured by other companies, such as refuse and recycling collection vehicles. In addition to vehicle and equipment sales, 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 18 principal manufacturing facilities in the U.S., three in Canada, two in Europe, and one in South Africa and provides products and integrated solutions to municipal, governmental, industrial, and commercial customers in all regions of the world.
    
    
      As described in Note 12 - Segment Information to the accompanying condensed 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.
    
    
      Economic Considerations
    
    
      A substantial majority of the Company's manufacturing operations are located within the U.S., and the substantial majority of the raw materials and component parts used to support the Company's domestic production processes are sourced from within the U.S. Similarly, in the locations where the Company manufactures products outside of the U.S, the respective supply chains and end customers are predominantly localized. While the Company primarily sources its products within the respective countries in which it manufactures, certain raw materials and component parts that go into making its products are imported into the U.S. from various countries, including China, and are subject to tariffs, sanctions, embargoes, export and import controls, and other trade restrictions. Additionally, the Company sells certain products to customers outside of the U.S., including in Canada, that are covered by international trade agreements and regulations, including tariffs. In 2025, the U.S. federal government has implemented or threatened broad new tariffs on imports, which has resulted in certain retaliatory tariffs being levied or threatened by a number of impacted countries. The U.S. federal government has also indicated that they may increase the existing tariffs, impose additional tariffs, and/or expand tariffs on goods imported from various countries. Although certain exemptions to the tariffs have been announced, their duration and scope remain unclear at this time, and such exemptions may be subject to change.
    
    
      While the tariffs implemented did not have a significant impact on the Company's year-to-date results, the long-term effects of those implemented then, or those that may be implemented in the future, remain uncertain. Although the Company believes that many of its products are included in the current tariff exemptions, the Company continues to closely monitor the evolving tariff and trade policy environment, which could change or alter these exemptions. Further, the Company is monitoring the potential for supply disruptions as a result of these trade disputes and negotiations, including those related to restrictions around exporting certain rare earth minerals and magnets by China, some of which are used in the production of certain of the Company's products. While the collective impact of these trade issues is uncertain, the Company continues to monitor the potential for higher product and operating costs and to evaluate the need to counteract any adverse effects on the Company's financial position, results of operations, or cash flow.

      Corporate operating expenses for the three months ended September 30, 2025 were $13.2 million, compared to $12.4 million in the prior-year quarter, with the increase primarily due to a $1.1 million increase in acquisition and integration-related expenses, net.
    
    
      Corporate operating expenses for the nine months ended September 30, 2025 were $38.7 million, compared to $33.7 million in the prior-year quarter, with the increase primarily due to a $1.4 million increase in acquisition and integration-related expenses, net, the non-recurrence of a $1.8 million gain associated with an insurance recovery in the prior-year period, as well as increases in information technology costs, and higher post-retirement and incentive compensation expenses.
    
    
      Seasonality of Company's Business
    
    
      Certain of the Company's businesses are susceptible to the influences of seasonal factors, including buying patterns, delivery patterns, and productivity influences from holiday periods and weather. In general, the Company tends to have lower equipment sales in the first calendar quarter of each year compared to other quarters as a result of these factors. In addition, rental income and parts sales are generally higher in the second and third quarters of the year, because many of the Company's products are used for maintenance activities in North America, where usage is typically lower during periods of harsher weather conditions.
    
    
      Financial Condition, Liquidity and Capital Resources
    
    
      The Company uses its cash flow from operations to fund growth and to make capital investments that sustain its operations, reduce costs, or both. Beyond these uses, remaining cash is used to pay down debt, repurchase shares, fund dividend payments, and make pension contributions. The Company may also choose to invest in the acquisition of businesses, like the acquisition of substantially all the assets and operations of Hog that was completed on February 12, 2025. In the absence of significant unanticipated cash demands, we believe that the Company's existing cash balances, cash flow from operations, and borrowings available under the Company's new credit facility will provide funds sufficient for these purposes.
    
    
      As of September 30, 2025, there was $94.4 million of cash drawn under the revolving credit facility, $117.2 million outstanding under the term loan facility, and $10.9 million of undrawn letters of credit under the 2022 Credit Agreement, with $569.7 million of availability for borrowings. The net cash flows associated with the Company's rental equipment transactions are included in cash flow from operating activities.
    
    
      The Company's cash and cash equivalents totaled $54.4 million as of September 30, 2025 and $91.1 million as of December 31, 2024. As of September 30, 2025, $18.6 million of cash and cash equivalents was held by foreign subsidiaries. Cash and cash equivalents held by subsidiaries outside the U.S. typically are held in the currency of the country in which it is located. The Company uses this cash to fund the operating activities of its foreign subsidiaries and for further investment in foreign operations. Generally, the Company has considered such cash to be permanently reinvested in its foreign operations and the Company's current plans do not demonstrate a need to repatriate such cash to fund U.S. operations. However, in the event that these funds are needed to fund U.S. operations or to satisfy U.S. obligations, they generally could be repatriated. The repatriation of these funds may cause the Company to incur additional tax expense, dependent on income tax laws and other circumstances at the time any such amounts are repatriated.
    
    
      Net cash of $157.5 million was provided by operating activities in the nine months ended September 30, 2025, compared to $140.7 million in the prior-year period, with the year-over-year increase primarily due to higher net income partially offset by the non-recurrence of a U.S. federal worthless stock deduction refund of approximately $14 million received in the prior-year period.
    
    
      Net cash of $101.3 million was used for investing activities in the nine months ended September 30, 2025, compared to $30.8 million in the prior-year period. During the nine months ended September 30, 2025, the Company funded $19.9 million of capital expenditures and made an initial payment of $82.1 million to acquire Hog. During the nine months ended September 30, 2024, the Company funded $32.1 million of capital expenditures.
    
    
      Net cash of $94.4 million was used for financing activities in the nine months ended September 30, 2025, compared to $97.2 million in the prior-year period. In the nine months ended September 30, 2025, the Company increased net borrowings under its revolving credit facility by $1.1 million, paid down $3.1 million under its term loan facility, funded payments of $4.3 million relating to the 2023 acquisition of Trackless, paid $11.5 million to acquire a previously-leased manufacturing facility, funded cash dividends of $25.6 million and share repurchases of $39.7 million, and redeemed $12.2 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 the nine months ended September 30, 2024, the Company paid down $64.4 million of net borrowings under its revolving credit facility and $1.6 million under its term loan facility, funded cash dividends of $22.0 million and share repurchases of $4.5 million, and redeemed $6.0 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.
    
    
      On October 29, 2025, the Company entered into the 2025 Credit Agreement, which amends and restates the 2022 Credit Agreement. The 2025 Credit Agreement increases the Company's revolving credit facility from up to $675 million to up to $1.1 billion, and includes a delayed draw term loan facility in an amount of up to $400 million. In addition, the Company may expand its borrowing capacity under the 2025 Credit Agreement by an aggregate amount of up to the sum of (x) the greater of (i) $500 million and (ii) 100% of Consolidated EBITDA for the applicable four-quarter period preceding such expansion, and (y) the amount of additional indebtedness (if any) that could be incurred without causing the Consolidated Total Net Leverage Ratio for the applicable four-quarter period preceding such expansion, on a pro forma basis, to exceed 2.75 to 1.00, subject to the approval of the applicable lenders providing such additional borrowings.
    
    
      The Company was subject to certain net leverage ratio and interest coverage ratio financial covenants under the 2022 Credit Agreement that are measured at each fiscal quarter-end. The Company was in compliance with all such covenants as of September 30, 2025. The Company will be subject to similar financial covenants under the 2025 Credit Agreement.
    
    
      The Company anticipates that capital expenditures for 2025 will be in the range of $40 million to $50 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.
    
    
      Contractual Obligations and Off-Balance Sheet Arrangements
    
    
      During the nine months ended September 30, 2025, there have been no material changes in the Company's contractual obligations and off-balance sheet arrangements as described in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, of the Company's Annual Report on Form 10-K for the year ended December 31, 2024.
