Thank you, Ian. Our first quarter performance represents a strong start to 2025 inclusive of first quarter records across consolidated net sales, adjusted EPS and adjusted EBITDA margin, thanks to the outstanding contributions from both of our groups. Within our Environmental Solutions Group, we delivered 9% year-over-year net sales growth and a 17% increase in adjusted EBITDA with higher production levels, growth in sales of our aftermarket offerings, proactive management of price cost dynamics and contributions from recent acquisitions representing meaningful year-over-year contributors. In what is typically a seasonally softer quarter, ESG's adjusted EBITDA margins expanded by 120 basis points year-over-year to approximately 20%, representing a new first quarter record and performance within the upper half of our current margin target range. On the back of our strong backlog and continued healthy order levels, our teams remain focused on building more trucks across our family of specialty vehicle businesses. As such, combined first quarter production at our two largest ESG facilities rose double-digits year-over-year. From a capacity perspective, our access to labor remains good, supply chain fluidity and supply chain consistency has improved materially 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. Additionally, we've made important investments at our Elgin Street Sweeper plant inclusive of several management hires, expansion of our hourly workforce and continued optimization of our fabrication processes. With these investments, we are confident that we can meet structurally higher demand requirements on the back of market share gains. Shifting to aftermarket. Demand for our aftermarket products and services remains high as revenues grew 11% year-over-year. Given strong rental utilization levels, our teams are diligently managing between ensuring sufficient rental equipment availability and used equipment sales to best serve our customers' needs. In the quarter, both rental revenue and used equipment sales grew double-digits year-over-year. In the aggregate, aftermarket represented approximately 26% of ESG revenue in Q1 this year. I'm particularly encouraged by the progress we've made on our various strategic initiatives in the quarter aimed at expanding our market share, some of which I will address throughout the call. As a reminder, through cycles, we target annual double-digit top line growth split roughly evenly between inorganic and organic growth. Execution on our strategic initiatives is an important component of that long-term growth algorithm as we look to drive organic growth in excess of end market growth rates. In the quarter, we reported double-digit organic growth in net sales of road-marking equipment and dump bodies driven by healthy end market demand, continued market share expansion efforts and our reputation for high quality products. In particular, our Ox bodies business with its primary manufacturing facility in Alabama continues to expand its geographic reach into key Southeastern markets such as Texas and Florida enabling strong market share expansion runway in critical markets with additional opportunities available going forward. Further, our most recent acquisitions also contributed positively to top line results with Standard adding approximately $6 million of incremental net sales in the quarter and HOG contributing around $5 million of net sales and a little over six weeks post-acquisition. On a full year basis, we continue to expect that HOG will contribute net sales of between $50 million and $55 million in 2025. Shifting to our Safety and Security Systems group, the team delivered another outstanding quarter with 8% top line growth, a 14% increase in adjusted EBITDA and a 110 basis point improvement in adjusted EBITDA margin. This improvement was primarily driven by a combination of volume increases and favorable sales mix. Within our SSG Group, our public safety business led the charge in form of 13% revenue growth with strong margin expansion as the team continues to execute on an active pipeline of opportunities within police end markets. Lastly, we had another strong quarter of cash generation with $37 million of cash generated from operations, up 17% over the prior year. As a reminder, on a full year basis, we target 100% cash conversion on a net income basis. Shifting now to current market conditions. Demand for our products and aftermarket offerings remain strong with our first quarter order intake of $568 million representing a 13% year-over-year increase and the highest ever quarterly order intake on record for Federal Signal. The addition of HOG's backlog contributed approximately $21 million of orders in the quarter. As such, excluding the impact of HOG's acquired backlog, orders increased 9% year-over-year. A record backlog at the end of the quarter provides excellent visibility for the remainder of the year and for certain key product lines into the first half of 2026. Within our end markets, publicly funded orders increased high-single-digits year-over-year led by strength in domestic street sweepers and public safety equipment primarily within our North American police business. Industrial orders rose double-digits led by strength in demand for dump truck bodies, safe-digging trucks and road-marking equipment as our teams continue to execute on several important strategic market share initiatives. As an example, within our dump truck body business, more than 75% of the revenue growth in the quarter was derived from conquest customers representing meaningful market share gains. This success has been a direct result of our strategic initiatives, beginning with our 80-20 processes aimed at rationalizing our product offerings, which has set the foundation to allow our business to expand geographically, while commanding industry leading lead times. This lead time advantage is an important competitive differentiator in the marketplace as it significantly decreases working capital cost for our distribution partners. Looking ahead, we are excited about future geographic white space opportunities within our dump truck body businesses and we are executing on various cross-selling initiatives across the enterprise such as driving higher municipal customer penetration. Lastly, our SSG team had a record order intake of $88 million in the quarter, up 17% compared to prior year as we continue to gain traction across our various market share initiatives within the police market. As an example, within North America, we continue to make progress expanding our share with the existing customers as we secured an order from a large strategic customer in the quarter that is expected to ship later this year. We are also seeing incremental opportunities to gain share across several US state agencies amidst an ever increasing need to keep our communities and law enforcement personnel safe. Similarly, our European public safety business VAMA secured a strategic contract win in France underpinning our future growth ambitions in Europe in this arena. In short, demand for our products and services remain strong. Our teams are focused on reducing lead times for certain product categories, while maintaining a healthy order intake. I now want to take a moment to expand on our various internal initiatives, many of which form the foundation through which we believe we can outgrow our end markets through cycles. Firstly, I want to address the current macroeconomic environment and how we are positioning Federal Signal in light of the recently announced global tariffs. From a high level perspective, our strategy remains largely unchanged. The vast majority of our supply chains are localized to the regions and countries in which we sell our equipment, which results in us sourcing more than 95% of our direct supplies from North America, the majority of which are from the United States. Going forward, we want to continue our strategy of producing in country for country and are proud of our domestic manufacturing operations in the United States, Canada and Europe. As such, we estimate that supplies directly sourced from China comprise less than 1% of our annual cost of sales. In fact, insourcing certain componentry out of Asia has been an important strategic lever within our SSG business for several years. Since 2022, we have invested several million dollars in three printed circuit board manufacturing lines at our University Park facility in Illinois. These additions have not only reduced our reliance on offshore Asian suppliers, but have also expanded our available capacity, while further increasing the quality of our products and realizing important cost savings. Given the recently announced tariffs, we are currently accelerating several other insourcing activities at SSG, including the addition of a fourth printed circuit board manufacturing line. While it is more difficult to quantify the exact indirect exposure resulting from tariffs, I would note that chassis costs have historically been treated as a pass-through item for many of our specialty vehicle products within the ESG Group. As such, we would expect that any potential resulting changes in the price of chassis would be directly passed on to the end customer. In addition, similar to the post-COVID inflationary period, we will look to strategically optimize our supply chains and continue to proactively manage price cost dynamics where necessary. Moreover, with 18 principal manufacturing facilities in United States and three in Canada, we have ample flexibility to strategically shift North American production as needed should the tariff environment change. Finally, from an underlying demand standpoint, we have seen no material changes in customer behavior in response to the announced tariffs thus far. We are also encouraged by the progress we are making on several important new product development projects across the enterprise that we are starting to accelerate as supply chains have stabilized. One of our core competitive advantages within the ESG Group is the scale and power of our specialty vehicle platform spanning several operational categories such as sourcing, supply chain optimization, our Federal Signal operational system, sales channel alignment, dealer development, aftermarket support, data analytics and new product development. As part of our growing specialty vehicle platform, we've established a centralized new product development group supporting our various business units led by our Chief Technology Officer. In the long-term, we believe the centralized approach for certain new product development initiatives will drive important scale advantages and ultimately support above market growth rates. One such example is the recent launch of our simplified control systems across many ESG vehicle categories. Originally launched in our Vactor vacuum truck business and currently being rolled out across our dump truck businesses, our new control system simplify ease of use and are aimed at alleviating one of our customers' greatest challenges at the moment, qualified labor availability. We are also excited about the progress we are seeing for adoption of two NPD initiatives, both of which are creating meaningful market share opportunities. Within our street sweeper business, we previously launched the RegenX product, a mid-dump regenerative air sweeper. This product enables us to strategically expand share in the historically underserved air sweeper market for Elgin and so far we have received outstanding customer interest. We are currently in the process of structurally raising our production capabilities to accommodate our expansion into this subset of the street sweeper market. In the fourth quarter of 2024, our SSG Group launched its Pathfinder Perimeter Breach Warning System, a patented system that enhances police officer safety by providing increased situational awareness and alerting law enforcement personnel of a threat within a 25 foot radius around the police car. When activated, the Perimeter Breach Warning System signals the officer audibly and visually to allow for sufficient reaction time. Initial interest in the product has been very strong and we see this innovation not only as market share additive within our public safety business, but we also see an opportunity to increase overall Federal Signal content per police car sold. Finally, we are pleased to announce that we have transitioned to multi-state territory within our exclusive dealer channel to five selected dealer partners with a combined 250 years of experience representing Federal Signal products. As a reminder, our exclusive dealer channel primarily serves certain municipal product lines including sewer cleaners, street sweepers and multipurpose maintenance vehicle and accounts for approximately 36% of total sales net sales. Turning now to our outlook for the remainder of 2025. Despite current global macroeconomic uncertainty, our record backlog provides us with visibility to the rest of the year and with our predominantly North American centric supply base and continued execution against our strategic and operational initiatives, we are raising our full year adjusted EPS outlook to a new range of $3.63 to $3.90 from the prior range of $3.60 to $3.90. At the midpoint, this revised guidance represents another year of double-digit growth and the highest adjusted EPS level in the company's history. Additionally, we are reaffirming our net sales outlook of between $2.02 billion and $2.1 billion. We are also reaffirming our expectations for double-digit improvement in pre-tax earnings and EBITDA margin performance in the upper half of our target range. This updated outlook assumes that the current trade agreements and recently announced tariff policies remain in place. Lastly, we are reaffirming our CapEx guidance of between $40 million and $50 million for the year. With that, we are ready to open the line for questions. Operator?
