Thank you, Ian. Our record-setting fourth-quarter performance represented a strong finish to a year in which we delivered the highest net sales and adjusted EPS in our history. Our fourth-quarter results included records across consolidated net sales, adjusted EPS, and adjusted EBITDA margin thanks to outstanding contributions from both of our groups. Within our Environmental Solutions Group, we delivered 6% year-over-year net sales growth and a 13% increase in adjusted EBITDA with higher production levels, contributions from acquisitions, and continued price realization representing meaningful year-over-year contributors. ESG's adjusted EBITDA margins expanded by 130 basis points year-over-year to approximately 21%, a new fourth-quarter record and towards the upper end of our current target range. As we pointed out in prior calls, we remain focused on raising our build rates for our extended lead time products, namely our sewer cleaners and street sweepers. As such, combined fourth-quarter production at our two largest facilities rose 5% year-over-year, primarily led by improved sewer cleaner production. From a capacity perspective, our access to labor remains good. Supply chain fluidity has improved, and our large-scale capacity expansions that we completed between 2019 and 2022 position us well to profitably absorb incremental volumes into our existing footprint. Shifting to aftermarket, demand for our aftermarket products and services remained strong as revenues grew 2% year-over-year, driven by strong performance in parts revenue and rental income. In aggregate, aftermarket represented approximately 26% of ESG revenue in Q4 this year compared to around 27% in Q4 last year. Our other vehicle-based businesses also contributed positively to results. For example, our road marking businesses achieved 34% year-over-year net sales growth on the back of broad-based strength across our product lines, driven by healthy end-market demand and continued market share expansion efforts. Similarly, our dump truck body businesses continued their momentum in the quarter with net sales growth of 29% year-over-year. Our industry-leading lead times, expansive product offerings across various brands, reputation for high-quality products, and geographic expansion efforts at our Ox Bodies and Rugby businesses are all resonating positively with customers. Shifting to our Safety and Security Systems Group, the team delivered another solid quarter with 1% top-line growth, a 3% increase in adjusted EBITDA, and a 40 basis point improvement in adjusted EBITDA margin. This improvement was primarily driven by a combination of price realization and efficiency gains. As I will address in more detail, we were particularly pleased with SSG's order intake in the quarter and believe this team has strong momentum heading into 2025. Lastly, we had another strong quarter of cash conversion with $91 million of cash generated from operations. For the full year, our cash conversion was 107%, ahead of our annual target of 100%. Shifting now to current market conditions, demand for our products and aftermarket offerings remain strong. With our fourth-quarter order intake of $446 million representing the second-highest fourth quarter on record. Lower chassis pass-through orders and the impact of the Standard acquisition represented a combined $8 million year-over-year headwind to reported orders in the quarter. Compared to the record order intake in the prior year quarter, orders were down 4% primarily due to lower orders from long lead time item products such as street sweepers and sewer cleaners where backlog stretches well into 2026. In fact, excluding street sweepers and sewer cleaners, our total fourth-quarter orders increased by approximately 13% year-over-year with notable demand for dump truck bodies, road marking and line removal products, public safety equipment, and our aftermarket offerings. In an effort to reduce current street sweeper and sewer cleaner lead time, our teams remain laser-focused on building more trucks while maintaining a healthy order intake. We have recently announced the acquisition of HOG Technologies for an initial purchase price of $78 million, and an additional $14.5 million for its primary manufacturing facility in Stuart, Florida. HOG Technologies is a leading manufacturer of truck-mounted road marking, line removal, and water blasting equipment with exposure to infrastructure, airport, and municipal end markets both in the US and internationally. HOG has established itself as a leading innovator in the road marking space, primarily due to its deep product expertise, technology leadership, and strong customer service. We are particularly excited about this acquisition, as HOG provides a natural extension of our road marking and water blasting businesses with a highly complementary product portfolio that significantly increases our reach into historically underpenetrated airports and international markets, which represented approximately 40% of HOG's equipment sales in 2024. Strategically, the road marking and line removal space represents a noncyclical essential service that we believe has secular tailwinds from the adoption of various autonomous-based vehicle solutions that rely on accurately and routinely striped roads irrespective of road construction activity. In addition to shared product development expertise and a broadening of product offerings geared to best serve our customers, we also see opportunities to further grow our water blasting business, Jetstream, which has long provided equipment to HOG. Moreover, similar to our other retail-based acquisitions such as Trackless, Groundforce, or Towhall, we see several multiyear synergy opportunities spanning channel alignment and cross-selling opportunities for other Federal Signal Corporation products, procurement savings, supply chain optimization, and further expansion of HOG's aftermarket parts and service business, which represents roughly 35% of HOG's net sales today. Lastly, while HOG's current EBITDA margins are slightly below ESG's margin target range of 17% to 22%, we anticipate HOG will operate within our margin target range by 2026 as initial synergies take hold as we execute on synergy opportunities. For the partial year of ownership in 2025, we anticipate HOG to contribute between $50 million and $55 million in net sales. We expect the acquisition to be accretive to cash flow and EPS inclusive of a preliminary estimate of intangible asset amortization. Before I provide more detail on our outlook for 2025, I want to spend a moment explaining our multiyear diversification strategy that we initially put into place in 2016 with the intent of muting earnings volatility through cycles. At a high level, roughly half our sales are tied to some sort of public funding mechanism, while the other half is sold to various industrial customers, which includes minor utility, oil, and gas exposure. On a more granular level, our publicly funded exposure can be dissected into several important categories with local water taxes representing the single largest individual funding mechanism, primarily supporting purchases of our sewer cleaner products. While local US water taxes represent the single largest bucket funding mechanism, in aggregate, that funding mechanism supports less than 15% of total net sales. Other forms of publicly funded mechanisms include US municipal budgets, local and state police budgets, Canadian local and provincial budgets, European federal, state, and local budgets, and US federal funds. US federal funds primarily support our military dump truck business within ESG and certain federally funded warning sales within SSG. In total, we believe our direct US federal exposure to be less than $10 million per year of total net sales. Further, given the essential nature of our products and associated high utilization levels through business cycles, the build-out of our aftermarket ecosystem, which today represents 26% of ESG's net sales compared to less than 10% prior to 2016, has been an important strategic pillar in our efforts to mute cyclicality. We expect to see further aftermarket growth in 2025. In short, we are not reliant on any one specific funding mechanism and continue to strategically pursue organic and inorganic growth initiatives that accelerate our strategy of manufacturing essential high-quality specialty vehicles and safety equipment that moves material, cleans infrastructure, and keeps our community safe. With that said, in the fourth quarter, industrial orders rose double digits year-over-year while publicly funded orders declined double digits year-over-year. On the industrial side, orders for road marking equipment, dump truck bodies and trailers, industrial vacuum trucks, and water blasting equipment all rose meaningfully. We are particularly excited about the continued execution of our geographic expansion initiatives within our dump truck body and trailer businesses, which saw Q4 orders rise by a combined 27% year-over-year. As we head into 2025, we see further opportunity to capitalize on healthy end-market demand. On the publicly funded side, orders for our domestic public safety equipment increased double digits, with orders for police products leading the charge. Our domestic public safety group continues to execute on market share initiatives and has successfully decreased lead times to pre-COVID levels, which has fueled a reacceleration in orders. Within the ESG segment, we continue to find new ways to expand our competitive advantage and harness the power of our growing specialty vehicle platform as we aim to unlock future growth opportunities in excess of end-market growth rates through operational excellence and best-in-class customer service. Specifically, we see incremental opportunities to align sales channels across our platform of businesses. We are also further accelerating the role of our Federal Signal operational system, driving increased aftermarket penetration across our vehicle-based businesses, and planning to reaccelerate new product launches as supply chains have stabilized across our ESG and SSG segments. As a result, we continue to see room for further margin expansion across both segments and expect EBITDA margins to improve year-over-year in 2025. Moreover, as outlined in our last earnings call, we see opportunities to proactively address areas of untapped share opportunity within our exclusive dealer channel. As a reminder, our exclusive dealer channel primarily serves certain municipal product lines, including sewer cleaners, street sweepers, and municipal maintenance tractors, and accounts for approximately 30% of total net sales. As part of that strategic alignment process, we are transitioning our relationship with a long-standing dealer partner with primary coverage across several Midwestern states to other qualified parties. Specifically, we are in the process of reassigning these territories, and we've received extremely strong indications of interest from ten outside qualified third-party entities, including a mix of current Federal Signal Corporation dealers and others who currently represent other OEMs. The level of interest in securing the rights in these territories is a testament to the strength of our brand and the growth opportunities that lie ahead. We expect to announce the recipients of these territories by the end of the first quarter. Although this transition had a minor adverse impact on the comparability of our Q4 orders and may further impact comparisons in Q1, we anticipate long-term benefits in the form of market share expansion across both new equipment sales and aftermarket revenue capture in those territories. We are also closely monitoring the ongoing potential for tariffs on internationally sourced products. As a reminder, our supply chain is predominantly US-centric, with only $30 million of direct purchases sourced from Mexico, Canada, and China. Nonetheless, we are exploring several mitigation strategies internally, including alternative domestic sourcing opportunities where available and/or price increases. Lastly, our M&A pipeline remains very active across both our ESG and SSG groups. Turning now to our outlook. Our current backlog provides excellent visibility well into the first half of 2026. With the ongoing execution against our strategic initiatives, we are confident that we will have another record year in 2025. For the full year, we are anticipating net sales of between $2.02 billion and $2.1 billion, double-digit improvement in pretax earnings, and EBITDA margin performance in the upper half of our target range. We are also currently expecting to report adjusted EPS of between $3.60 and $3.90 per share for the year, which at the midpoint would represent another year of double-digit growth and the highest adjusted EPS level in the company's history. Given that seasonal effects typically result in Q1 earnings being lower than subsequent quarters, we are currently expecting Q1 to represent between 19% and 20% of our full-year earnings, roughly in line with last year. The combination of continued healthy demand for our new equipment, parts, and aftermarket services, and excellent visibility with a strong backlog gives us confidence in our ability to deliver another year of record results in 2025. Lastly, we expect capital expenditures to be between $40 million and $50 million for the year. In closing, I want to express my profound thanks to our employees, suppliers, dealer partners, and stakeholders for a tremendous 2024. With an active M&A pipeline, ongoing investment in new product development, large backlog, available capacity, and execution against our strategic initiatives, we are well-positioned for long-term sustainable growth. With that, we are ready to open the line for questions. Operator,
