Thank you for standing by. This is the conference operator. Welcome to the Federal Signal Corporation First Quarter 2022 Earnings Conference Call. As a reminder, all participants are in listen-only mode and the conference is being recorded. After the presentation, there will be an opportunity to ask questions. I would now like to turn the conference over to Ian Hudson, Chief Financial Officer. Please go ahead.

Good morning, and welcome to Federal Signal's first quarter conference call. I'm Ian Hudson, the company's Chief Financial Officer. Also with me on the call today is Jennifer Sherman, our President and Chief Executive Officer. We will refer to some presentation slides today as well as to the earnings news release, which we issued this morning. The slides can be followed online by going to our website, federalsignal.com, clicking on the Investor Call icon and signing into the webcast. We have also posted the slide presentation and the earnings release under the Investor tab on our website. Before we begin, I'd like to remind you that some of our comments made today may contain forward-looking statements that are subject to the safe harbor language found in today's news release and in Federal Signal's filings with the Securities and Exchange Commission. These documents are available on our website. Our presentation also contains some measures that are not in accordance with US Generally Accepted Accounting Principles. In our earnings release and filings, we reconcile these non-GAAP measures to GAAP measures. In addition, we will file our Form 10-Q later today. I'm going to begin today by providing some detail on our first quarter results before turning the call over to Jennifer to provide her perspective on our performance, market conditions and our outlook for the remainder of the year. After our prepared comments, Jennifer and I will address your questions. Our consolidated first quarter financial results are provided in today's earnings release. In summary, we delivered solid financial results for the quarter with 18% top line growth and EBITDA margin performance within our target range despite a slow start to the year. Consolidated net sales for the quarter were $330 million, up $51 million or 18% compared to last year. Consolidated operating income for the quarter was $28.5 million, up $700,000 or 3% compared to last year. Consolidated adjusted EBITDA for the quarter was $42.2 million, up $1 million or 2% compared to last year. That translates to a margin of 12.8% in Q1 this year, compared to 14.8% last year. GAAP EPS for the quarter was $0.33 per share, compared to $0.36 per share last year. On an adjusted basis, EPS for the quarter was $0.34 per share, compared to $0.38 per share last year. Order intake for the quarter was again outstanding and we again reported record orders in the first quarter, surpassing the previous high, which we set in Q4 last year. In total, orders in Q1 this year were $453 million, an increase of $69 million or 18%, compared to Q1 last year. Backlog at the end of the quarter was $751 million, another all-time high for the company and an increase of $342 million or 83%, compared to Q1 last year. In terms of our group results, ESG's net sales for the quarter were $274 million, up $46 million or 20% compared to last year. ESG's operating income for the quarter was $26.8 million, compared to $27.1 million last year. ESG's adjusted EBITDA for the quarter was $39.3 million, in line with the prior year. That translates to an adjusted EBITDA margin for the quarter of 14.3%, compared to 17.2% last year. ESG reported total orders of $388 million in Q1 this year, an improvement of $63 million or 20% compared to last year. SSG's net sales for the quarter were $56 million, up $5 million or 10% from last year. SSG's operating income for the quarter was $7.9 million, up $700,000 or 10% compared to last year. SSG's adjusted EBITDA for the quarter was $8.9 million, $100,000 or 9%. That translates to an adjusted EBITDA margin for the quarter of 15.9%, compared to 16.2% last year. SSG's orders for the quarter were $65 million, up $5 million or 9% compared to last year. Corporate operating expenses for the quarter were $6.2 million, down $300,000 or 5% compared to last year. The reduction was largely due to favorable mark-to-market adjustments of post-retirement reserves. Turning now to the consolidated income statement, where the increase in sales contributed to a $6.9 million improvement in gross profit, including the effects of production inefficiencies that we encountered in the early part of the year. Consolidated gross margin for the quarter was 22.9%, compared to 24.7% last year. On a year-over-year basis, our pricing actions largely covered our cost increases. As we had anticipated, this cost inflation did create some margin pressure in Q1, but with the actions we have taken, we expect more price realization and margin improvement as we move forward. As a percentage of sales, our selling, engineering, general and administrative expenses for the quarter were down 50 basis points from Q1 last year. Other items affecting the quarterly results include a $700,000 increase in amortization expense and a $200,000 increase in interest expense. Tax expense for the quarter was up $2.1 million, largely due to the recognition of $1.9 million fewer excess tax benefits from stock compensation activity as compared to last year. As a result, our effective tax rate for the quarter was 25.7%, compared to 18.4% last year. At this time, we continue to expect our full year effective tax rate to be approximately 25%. On an overall GAAP basis, we therefore earned $0.33 per share in Q1 this year, compared with $0.36 per share in Q1 last year. To facilitate earnings comparisons, we typically adjust our GAAP earnings per share, for unusual items recorded in the current or prior year quarters. In the current year quarter, we made adjustments to GAAP earnings per share to exclude acquisition-related expenses. On this basis, our adjusted earnings for the quarter were $0.34 per share, compared with $0.38 per share last year. Looking now at cash flow, where we generated $7 million of cash from operations during the quarter. We ended the quarter with $291 million of net debt and availability under our credit facility of $162 million. Our current net debt leverage remains low, even after the funding of the purchase of our University Park facility during the quarter for approximately $28 million. With our financial position remaining strong, we have significant flexibility to invest in organic growth initiatives, pursue strategic acquisitions, and return cash to stockholders through dividends and opportunistic share repurchases. On that note, we paid dividends of $5.5 million during the quarter, reflecting a dividend of $0.09 per share, and we recently announced a similar dividend for the second quarter. We also funded $13.6 million of share repurchases during the quarter. That concludes my comments. And I would now like to turn the call over to Jennifer.

Thank you, Ian. During the quarter, our businesses worked diligently to mitigate the impact of ongoing supply chain volatility and increased coronavirus-related disruption that we experienced at many of our facilities in January. As we mentioned on our last earnings call, we were hit particularly hard by an escalation of COVID-related absences in January at essentially all of our facilities. Overall, we estimate that we lost approximately 20,000 direct labor hours across our facilities in January alone. Thankfully, we saw a dramatic reduction in cases in February, which continued into March. After a slow start, we also noted improvement in chassis deliveries within our dump truck business in March. These factors contributed to a meaningful improvement in production levels and customer deliveries as the quarter progressed. Overall, our top line increased by over $50 million year-over-year with both of our groups reporting double-digit revenue growth, including benefits from pricing actions and contributions from recent acquisitions. Within our Environmental Solutions Group, the 20% year-over-year sales increase was partially driven by higher sales of safe digging trucks, dump bodies, metal extraction, support equipment and trailers. Our strategy to diversify our revenue streams by broadening our aftermarket offerings also continued to provide benefits in the first quarter, with tightness in the supply chain and extended lead times for new equipment deliveries, we again saw increased demand for rentals, parts, and used equipment sales. Overall, aftermarket revenues for the quarter were up 20% compared to last year, representing approximately $12 million of ESG's year-over-year revenue growth. We continue to be encouraged by the resilience and growth opportunities of our aftermarkets group. Within our Safety and Security Systems Group, the 10% sales improvement was primarily due to higher sales of public safety equipment. With our efforts to expand our supply base and execution of our ETI principles to in-source production of certain materials, component availability for these products has improved in recent months, which resulted in an increase in shipments compared to last year. Despite the challenges we faced during the quarter, our teams were successful in delivering a consolidated EBITDA margin within our target range. Consistent performance within our target range is a key focus of ours, and we continue to believe this level of sustained operational excellence differentiates Federal Signal from many of our specialty vehicle peers. Demand for our products and our aftermarket offerings remains at unprecedented levels. The momentum has been across the board with orders from both municipal and industrial customers, up around 25% year-over-year. Within our municipal markets, we are seeing the benefits from the American Rescue Plan Act, which in 2021 earmarked $350 billion for state, local and territorial governments for a variety of purposes, including the maintenance of essential infrastructure such as sewer systems and streets. The first $170 billion tranche started to be distributed last year, and we are seeing that translate to new business with our first quarter orders for sewer cleaners and street sweepers, both up by more than 40% compared to last year. With the second $175 billion tranche expected to be distributed this year, including multi-year appropriations and spending deadlines, we expect to see a prolonged meaningful tailwind from these stimulus packages. This positive sentiment was widely shared by our customers and dealer partners in recent market planning meetings. Within our public safety end markets, demand remains strong. Our order backlog for public safety equipment at the end of the quarter was more than double that at the same time last year. We are actively working to try to reduce the current lead times in the backlog. On the industrial side, with the recent increase in oil prices, we have seen higher demand for many of our ESG products, including vacuum motors, water blasting equipment, and safe digging products. In fact, our first quarter orders for safe digging trucks were up 90% compared to the prior year. Rental interest from industrial contractors was also high, and our Jetstream business reported record revenues for its water blasting equipment rentals in the first quarter. Within SSG, we've also seen a significant uptick in quoting activity for industrial signaling equipment and warning systems. With the increased demand causing lead times for certain products to become extended and with the need for certain customers to secure a chassis, we again saw some dealers placing advanced orders during the quarter, which could cause some distortion in the comparability of our orders as we move through the year. Now turning to supply chain where for the majority of our vehicle-based businesses within ESG, chassis deliveries from the various suppliers that we utilize have largely remained on schedule with committed delivery dates. Within our dump truck businesses, where the customer always provides the chassis, we expect the flow of chassis may be volatile for the next several quarters. However, we were encouraged with the volume of chassis deliveries that we saw in March. Shortages of hydraulics, pumps, and certain electrical components continue to make production challenging, but our teams continue to be creative and nimble in adapting and identifying solutions to these supply chain challenges. For example, our teams have secured alternative suppliers, purchased certain buffer inventory, started to in-source or re-engineer products where possible and modified production schedules based on component availability. As we look ahead, we are closely monitoring the recent coronavirus-related lockdowns in China, while a direct exposure to sourcing from China is insignificant, the indirect impact it may have on our supply base is currently uncertain. On the geopolitical front, we have no operations in Ukraine, Russia, or Belarus, and we do not have any direct supply chain or customer exposure. In response to the unprecedented inflationary environment, our teams continue to take proactive measures such as locking in pricing and securing availability of steel based on forecasted needs and implementing price increases and surcharges. To date, we have not experienced significant order cancellations following the announcement of our pricing actions. Our access to labor remains strong, and our teams have built a great culture, which has helped us to differentiate ourselves in our ability to attract and retain talented and dedicated employees at the majority of our facilities. As an example, at our largest manufacturing facility in Streator, Illinois, over many years, the team has worked extensively with the local community to build awareness around job opportunities. These efforts have included partnering with local high schools and colleges to career fairs, open shop nights, scholarship programs, weld and fabrication programs, and even high school signing days where students can declare they are joining the Vactor team. As a result of the team's continued efforts, the team has been successful in filling 40 positions to support increased volumes since the beginning of the year. During April, we also successfully renegotiated our union contract, which covers about half of our employees at our University Park, Illinois facility, which is home to our domestic SSG operations. Access to a strong talent base was a key factor in our decision to purchase this facility during the first quarter. Simply stated, our access to labor is generally good and is not currently a constraint. We have a number of ESG-related initiatives that focus on diversity, equity, and inclusion. For example, we are pleased to report that 60% of our current executive officers are gender diverse, placing Federal Signal well above the average of our industry and peer group. We also have an ongoing focus on the environment and process improvement. For example, at our manufacturing facility in Tishomingo, Mississippi, we have recently embarked on a foam reclamation project aimed at dramatically reducing the purchase of new foam, thus reducing landfill content. I now wanted to take a few minutes to provide an update on a couple of our growth initiatives. We remain bullish about our long-term prospects with respect to safe digging and continue to identify new applications for this technology. For example, increased demand and spend on broadband infrastructure is generating additional interest in our broad range of product offerings that can vacuum excavate and/or convey materials in a safe and efficient manner. Our equipment is designed to meet the production capacity and maneuverability needs to complement the multiple horizontal drilling and trenching methods used to install this infrastructure below the surface. With the infrastructure builds, $65 billion allocation towards broadband infrastructure, we anticipate continued demand for all of our equipment that is integral to the process of improving and expanding the infrastructure. During the quarter, we introduced the TRUVAC truck trailer, the newest product offering in our expanding safe digging portfolio. With strong order activity in the first quarter, we've already filled the majority of production slots for the year. Electrification also remains a key area of investment, we have launched our plug-in hybrid electric broom bear sweeper and begun demonstrations of our hybrid 3-wheel Pelican Sweeper. Demand for demonstrations of these products within our dealer network remains high. In collaboration with multiple chassis manufacturers, our teams plan to begin field testing an all-electric truck mounted sweeper later this year. Working with a number of different partners, our research and development teams continue to explore other ways to fully integrate electrification into our suite of products. As an example, within our dump truck business, our Rugby team successfully incorporated our new DuraClass body platform into a fully electric Class 7 chassis in March at the 2022 Work Truck Show. We expect this to be the first of several collaborations with chassis manufacturers who are seeking to demonstrate dump truck bodies or platforms on their electric chassis. Our aftermarket business has grown to represent approximately 30% of ESG revenues, and we see additional opportunities to grow that business by expanding into new geographies, we believe to be underserved. On the acquisition front, we are making good progress integrating our recent acquisitions, Ground Force and Deist, and we were pleased with their performance in the first quarter. Our deal pipeline remains very active, and we continue to expect M&A to be an important part of our future growth. Turning now to our outlook for the rest of the year. We remain encouraged by conditions in our end markets, the ongoing execution against our strategic initiatives, and the order trends that we've seen over the last few quarters. Although we expect the volatile supply chain environment to continue, we are encouraged with how our teams have navigated through these challenges so far this year. With our first quarter performance, our record backlog, and current expectations of component availability, we are raising the low-end of our full year adjusted EPS outlook range by $0.04, establishing a new range of $1.80 to $2. We are also increasing the low-end of our full year net sales outlook range by $30 million, establishing a new range of $1.38 billion to $1.45 billion. With our talented workforce and capacity expansions at several facilities, our businesses are well positioned for long-term, sustainable continued growth once the supply chain environment normalizes. Demand for our products is at an all-time high with federal stimulus and infrastructure legislation offering potential for further multi-year momentum. At this time, I think we are ready for questions.

Thank you. Our first question comes from Steve Barger of KeyBanc Capital Markets. Please go ahead.

Good morning, Steve.

Hey. Good morning, guys. This is actually Ken Newman on for Steve.

Hi, Ken.

Okay.

Morning. So my first question is I'm curious, if you could just comment on where price cost ended up in the quarter, and just any thoughts on how we should think about price cost spread that's implied at the midpoint of the updated guidance here?

Yeah. Hey, Ken, this is Ian. So as it relates to the price cost, in terms of the absolute dollars, we feel that on a year-over-year basis, the actions that we took last year effectively covered the cost increases that we saw on a year-over-year basis. So that was actually slightly better than what we were anticipating. And the main reason for that was because we were able to ship more than we anticipated on the dump truck side of the business with the chassis flow that we saw in March. So in absolute dollars, it was neutral. Now obviously, from a margin standpoint, there was some pressure created with the inflation that we saw. As we move forward for the rest of the year, we are expecting that to continue to improve as we flush out more of the backlog and more of that shift. So yeah, we are expecting margins to improve as we realize more price going forward.

And I guess, I'll add there, we took a number of additional pricing actions in Q1, and we should see the benefit of that as we move through the year.

Okay. Yes. So that leads into my follow-up question, which is just given that it sounds like the supply chain is improving a little bit better than you expected on the chassis side obviously, you're implementing more pricing actions and you expect the margins to get better from here. I just wanted to ask about the thought process about not bumping the higher end of the guidance. And just how much conservatism is kind of embedded in the higher end there?

Yeah. I guess I'll make a couple of comments. As we talked about, it was a rough January and our performance improved as we moved throughout the quarter. And just to remind you, there are two aspects to that for our non-dump truck businesses. We are seeing – the situation is very similar to what it was the last time we spoke. We're getting the chassis that the chassis OEM is committed to deliver to us. On the dump truck side of the business, where we never own the chassis, we are beholden to others, and we did see some improvement in March. As we mentioned in our prepared remarks, we expect in the dump truck side of the business for that to remain volatile as we move throughout the year. On the non-chassis supply chain front, I would say, it's about the same as it was when we spoke to you six weeks ago. You can sub in different components – but what's changed is our teams are pretty scrappy and getting better and better at dealing with it. So, given the uncertainty in the market, particularly around chassis availability for our dump truck business, we felt comfortable raising the low-end, and we'll update the guidance as we move throughout the year.

Understood. If I could just squeeze one more in, I think last quarter, you had mentioned this – the thought about the year kind of being a 40-60 split between the first half and the second half. It sounds to me like the quarter came in better than you expected. So is that 40-60 split still kind of in play, or just how should we think about the cadence between the first and second half at this point?

Yeah, Ken. I think that's still a reasonable estimate.

Understood. Thanks. I'll get back in the line.

Thank you.

Our next question comes from Felix Boeschen of Raymond James. Please go ahead.

Good morning, Felix.

Hey, Good morning, everybody. Hey, Jennifer. Hey, Ian. Jennifer, I was curious if we could talk a little bit about the sustainability of the strength you've seen in the aftermarket book, again, I think, up 20% year-over-year. You did mention some geographic expansion maybe in that part of the business. I was hoping you could maybe expand on both commentary what happens if new truck production increases? Do we see sort of aftermarket ebb or secular how sticky is sort of this current run rate you're seeing?

The aftermarket business has a seasonality component to it. Based on – that's really driven by rentals. So I'll start with that comment. So it can vary quarter-to-quarter. But we have a number of strategic initiatives around our aftermarket business. You referred to one of them, the geographic expansion. We're in the process of executing on that over the next several quarters, and we're excited about the opportunity that presents for the company. In addition to that, we have a number of other initiatives, particularly around used equipment and around parts. We've got a project where we are actually manufacturing certain will fit parts. And although we're in very early stages, it's gotten off to a strong start. So it's also just a super team. And I'm encouraged by the opportunities I see for that group as we move forward. My final comment would really be around the resilience that we've seen over the last couple of years for our aftermarket business. And we think that, that is a critical component for Federal Signal as we move forward.

Helpful. And then I was just hoping to follow-up on the chassis supply commentary you made earlier. It sounds like from a dump body perspective, margin ended up being demonstrably better. I'm curious, though, if you could maybe talk about predictability of chassis flow in general and maybe as it relates to your own internal manufacturing efficiencies or inefficiencies because of that. Has that improved at all as the OEMs are talking to you?

Yes. I think, Felix, externally for what we internally refer to as the legacy chassis-based business as we have. So that would be the Vactors, the Elgins. What we're seeing there is that the chassis OEMs are sticking to the committed delivery dates, which helps us run a more efficient manufacturing operation. What wasn't happening last year is that, that was very sporadic, and so that made production highly inefficient. And so for the majority of our vehicle-based businesses within ESG, that is staying on schedule. So that gives us encouragement, and we can plan accordingly. The area where we have less control is on the dump truck side where the customer provides the chassis. And so you're absolutely correct. In March, we saw a noted improvement in the flow of chassis. In February, I think we were getting about half of what we needed to fulfill the demand. That certainly improved in March. April has been on track. But again, I think we're a little cautious in the sense that we don't control the flow of chassis there and one month doesn't necessarily create a trend, but we are certainly encouraged with what we've seen.

Yes. I would like to add to Ian's comments regarding our Vactor and Elgin business. Chassis availability is not significantly impacting production efficiencies. The production efficiencies we are witnessing are largely due to the performance of other components, such as hydraulics, which are causing inefficiencies in the business.

Got it.

We're getting the chassis OEM promised to us.

Thank you. Appreciate it.

Our next question comes from Michael Shlisky of D.A. Davidson. Please go ahead.

Good morning.

Yes. Good morning, everybody.

Hi, Mike.

Can I first highlight the significant growth in our backlog this quarter? Could you share how much pricing influenced that backlog growth and also the topline growth for the quarter?

Yes. In relation to the topline, we recorded just over $50 million in revenue year-over-year, which is about 18%. Of that, approximately 11% was due to organic growth, and around half of that was attributed to price increases. This reflects the revenue for the quarter, and the orders are expected to be in a similar range.

Great. Can I just turn to University Park now. I saw you bought that in the quarter, great stuff. Are there any major projects that have to take place there now that you own it, that you couldn't or didn't do before as part of this year's capital budget plan?

We have several low-level investments we are considering for both our University Park and Elgin facilities. As you remember, we acquired Elgin in the fourth quarter and are focused on enhancing efficiencies there.

But Mike, in terms of dollars, nothing of a particular magnitude, I still think we continue to expect our CapEx absent the UP facility purchase to be in the range of about $25 million to $30 million, which is more in line with what we would typically expect. So nothing significant in terms of CapEx required at UP.

Okay. And no disruptions or shutdowns planned for that facility either, correct?

No.

Okay, perfect. And then just turning back to the backlog quickly. I wanted to touch on the timing as well. I know you've had great growth. Is all that backlog planned for 2022 delivery? And is the tenure of the backlog longer or shorter than you normally would have?

Not everything will shift in 2022, Mike. It varies by product line, but particularly in sewer cleaners, where we have seen really strong demand, we are looking into the first quarter of 2023. The lead times are longer than we would prefer, and we are actively working to reduce them due to challenges and constraints in the supply chain. They are currently a bit longer than we would like, so we are making efforts to address that.

I guess to clarify there, are you hearing from customers that they want to make a multi-year order or commitment to get a better place in your production schedule? Are they looking at the plan ahead further than they have in the past? I'm just kind of curious if people are prioritizing this type of equipment more than they have in the previous years.

We have very few multi-year orders. As we noted in our prepared comments, we do have certain customers that we believe have placed their orders earlier than they might otherwise because of our extended lead-times. However, we take a close look at demand, and it's really been across the board. And we believe that between the infrastructure bill and the American Rescue Plan, that that will provide kind of multi-year tailwinds for our equipment.

Got it. Got it. Well, thanks so much. I'll pass it along. I appreciate it.

Thank you.

Our next question comes from Chris Moore of CJS Securities. Please go ahead.

Yes, good morning. This is Dan Moore for Chris. Good morning, Jennifer. Good morning, Ian. Thank you for the insights. To start, can you provide an estimate of the margin lost in Q1 due to the inefficiencies from supply chain issues and COVID impacts in your plants?

Yes, it was primarily felt within ESG, and you’ll see the impact on the gross margin we experienced within ESG. We were down about 170 basis points, mostly due to inefficiencies that occurred mainly in January and a bit into February. Another factor was the price cost impacts. While we were effectively neutral in absolute dollars on a year-over-year basis, there was some margin pressure from that situation. Additionally, the margin within ESG was affected by a higher concentration of chassis that we supplied. Our efforts to procure more chassis led to an increase in chassis revenue, which has a dilutive margin impact. Specifically, there was about $6 million in additional chassis revenue year-over-year, which influenced the gross margin within ESG. These are the primary drivers of the margin change you see in Q1 within ESG.

Very helpful. You mentioned that the 60-40 split between the second half and first half still holds. Can you provide any additional insights or comments on the cadence over that time frame, considering the various factors involved, including the price increases that you're still implementing? How should we approach the margin implications in the guidance? Thanks.

Yes. Dan, if you examine the historical trends influenced by the seasonality of our aftermarket business, Q2 and Q3 generally perform well, with Q3 likely being the strongest due to a lot of activities occurring during the summer months, along with robust rental activity. We anticipate that pattern will continue. Additionally, Q4 is usually strong as well, especially on the municipal side, where SSG tends to finish the year on a high note. Therefore, we expect the aftermarket business to follow similar patterns this year as it has in the past.

Got it. And then lastly, it doesn't sound like it. It sounds like demand remains strong across the board and rising. But any impact that you can discern from a rising interest rate environment on demand at this point or any of those discussions with customers or is it more about getting as much product as they can. Thank you again for the color.

Yes. We have not observed any impact on demand from our customers. One factor that sets us apart is the broad range of our product offerings. We obviously have new equipment, as well as strong demand for used equipment rentals. A key strategy has been to provide tailored solutions for our customers' specific needs, and we believe this approach will continue to be advantageous as we move ahead.

All right. Thanks, again. Best of luck for the remainder of the year.

Thank you.

Our next question comes from Greg Burns of Sidoti & Co. Please, go ahead.

Good morning, Greg.

Good morning. Sort of a follow-up a little bit on the chassis. So it seems like your suppliers are able to produce to what they promised. But are you seeing anything in terms of maybe potential for improvement or them to be able to actually increase the supply of chassis to you, or anything in the conversations you're seeing or anything out in the macro or in the industry that would give you hope that maybe you start to see some increase in availability?

Yes. Again, I want to divide my comments into two sections. So first, I'll talk about Vactor, Elgin, our legacy businesses, which is a different experience than the dump truck businesses. So the Vactor, Elgin side, as we talked about, we're getting what the chassis manufacturers promise, but we are in allocation. We have been successful in terms of going out and procuring some additional chassis outside the normal channels. So, right now, chassis are not our constraint for those businesses, it's really the other component parts, primarily hydraulics. So if we were to see some relief with respect to those other component parts and hydraulics is just one example, we're very focused on reducing our lead times and reducing our backlogs, because they're longer than we'd like them to be. On the dump truck side of the business, where we don't supply the chassis, we, again, are beholden to our customers and dealers to supply those chassis. And, as Ian mentioned, we saw improvement in March. One month does not make a year, and we continue to monitor that situation. But, again, we are very focused on reducing those backlogs.

Could you provide an estimate of the size of the oil and gas market and how it compares to the last time we experienced a spike in oil prices? What was the scale of that business for you then? Additionally, how might your business be better positioned this time, considering the new products you have or the strengthened aftermarket to take advantage of that opportunity?

Yes. In terms of our current contribution, we estimate it's around $20 million to $30 million in revenue. Looking back at the peak from 2015 to 2016, when oil prices dropped significantly, we believe we lost about $80 million in revenue at that time, mainly from new equipment sales, particularly in safe digging vehicles. Since then, we've observed a shift in revenue towards more rental income and used equipment sales. We've certainly noticed a renewed demand from oil and gas customers for rentals, especially for our safe digging trucks, which make up a significant part of our rental fleet. Our rental partners are also looking to replenish their fleets, benefiting from strong used equipment sales. While we're not back to the peak levels, there is some momentum in that direction; however, we don’t expect to reach the same heights we experienced in 2015 and 2016 due to the shift in the nature of our revenue from new equipment sales to more rental and used equipment sales.

Yes. Other products that increasing oil prices can have a positive impact on would include our Jetstream product, our Guzzler products, and a small portion of our SSG products.

Okay. Thank you.

Our next question comes from Walt Liptak of Seaport. Please go ahead.

Good morning.

Hi, good morning. Thanks. So great quarter. Maybe a follow-on to the last one about the O&G related product. And I think you are number that TRUVAC orders were up 90%, I wonder if you could help us with that. Does that mean it went from like 15 or 20 up to 30, 40. What's the level that we're at?

Yes, it's more in the $35 million to $40 million range for orders in the quarter. When we provided those statistics, it specifically referred to the pure play TRUVAC trucks and did not include the sewer cleaner trucks. Many of our sewer cleaner orders now come with a hydro package, making them multipurpose vehicles. Additionally, those sewer cleaner orders in the quarter increased by 43%, translating to about $20 million in year-over-year improvement. The combination of these two factors indicates the growth we are experiencing on the safe digging side.

We also saw an increase in TRUVAC demonstrations in the first quarter of this year compared to last year, which is a positive sign. Additionally, we are continuously expanding our portfolio of TRUVAC products with the introduction of our trailer trucks product.

Okay. Yes, that's great. That's good to see. What's the price differential between the TRUVAC truck and one of the trailers?

The trail is light and relatively small in terms of its contribution to that 90%. Since it's a brand-new product we've just introduced, the dollar amount at this stage is also fairly small. However, we are aiming to grow it as we generate more interest in the product.

Yes. I guess my question was, is that half the price of the TRUVAC or three quarters of the price of the TRUVAC for the trailer?

It's important to note that the price is significantly lower than that of a truck-based product. We're discussing a range of $80 to $120 for the trailer, while the costs for the full-size trucks can be several times higher.

It opens up a new end market for us and provides another opportunity for our customers to remain engaged with us.

Okay. Great. And then on the point that you made about rental, the shift towards rental for the O&G markets this time around, could you provide a little bit more detail about why you think that is? Are you picking up more rental customers, or is it your rental that's that you're pushing? Like why is it that this time around the service providers will be renting more trucks than owning them?

Well, if you go back to 2016, there just weren't – there were many more trucks available now, the rental business for our products was really in the infancy. So, there are a lot more trucks available both from us and our valued rental partners. So that's an important component as we look at those numbers. We also see this as an alternative. And again, some end customers rent, some end customers want to own but it gives them an opportunity to either supplement their equipment or depending on the nature of the project, it gives them an opportunity to rent to own in some situations.

Okay, great. In your comments about mergers and acquisitions, it sounds like you have capital available and you're continuing to build your pipeline for M&A. Do the supply chain issues and inflation affect your enthusiasm for M&A, or are you just as active as you were prior to last year when conditions tightened?

Yes. I think we've proven to be very disciplined acquirers and we're going to continue to employ that same methodology. But our M&A pipeline is active, and we believe that it will be a meaningful part of our growth story going forward.

Okay. Great. Okay. Thank you.

Our next question is a follow-up from Steve Barger of KeyBanc Capital Markets. Please go ahead.

Hey thanks. It’s Ken Newman. Appreciate the follow-up here. I just wanted to follow on to the rental comments just now. I guess I'm trying to get a better sense of what the expectation for rental growth is into the second quarter and into the second half? And specifically, just any color you can give in terms of how much of that is coming from better fleet growth versus higher rental rates? I imagine the time utilization for those fleets is pretty tapped out at this point. But any color there would be helpful?

There are a few factors contributing to this. Firstly, as we've mentioned, there is a seasonal aspect generally in the second and third quarters during the warmer months in northern North America where we experience increased time utilization and financial utilization. The Canadian market plays a significant role in our rental fleet and the opportunities associated with it. Secondly, we've observed a rise in rental rates from both our company and our rental partners. Additionally, we've made some enhancements to our rental fleet, which can vary from quarter to quarter based on how much we sell from the fleet and the demands of our customers. We also discussed geographic expansion as a key strategic initiative for the aftermarket group, which further opens up additional opportunities for us.

Is there any way you can quantify just how much of the backlog is slated for the rental fleet versus true third-party deliveries?

Yeah, Ken. The backlog that we cite is all external. We don't include in what we talk about externally anything that's going into our own rental fleet.

Understood. And then my last follow-up here is just, kind of, also an idea of just how we should think about your expectations for aftermarket growth at this point? Obviously, it's been very strong given the tight supply chain dynamics. Is there further upside or just how much more do you think you can be flexing on price, just given how tight the supply chain is and whether you're seeing any pushback from pricing pushes on the aftermarket side at this point?

I believe that aftermarket sales have now grown to about 30% of ESG's revenues, with the potential for further growth. The demand and interest we've observed in rental fleets during the first quarter, which is usually the slowest for rentals, have been encouraging. Additionally, on the parts side, extended lead times for new equipment have led people to refurbish their existing equipment, resulting in increased part sales. Parts, being the largest segment of our aftermarket revenues, increased by about 14% in the first quarter compared to the same period last year. I anticipate continued interest in parts, rentals, and used equipment sales due to the current environment with extended chassis lead times affecting our products. Therefore, we might see aftermarket sales increase slightly beyond 30%. This underscores why we consider this a crucial strategic initiative for us.

Also, I believe that the infrastructure bill will create additional opportunities not only for whole goods sales as we've talked about, but also for our aftermarket group.

Yeah, that makes sense. I appreciate the time.

Thank you.

Thanks Ken.

Our next question comes from a follow-up from Walt Liptak of Seaport. Please go ahead.

Hi. Thanks for taking my follow-up too.

Of course.

I wonder if you could help us with understanding the 2022 guidance and the low end. And so my question is, if you were to come in at the low end of the range, why do you think that would be? Is it because you have like an increase in supply chain problems again for another round of Omicron, what do you think it is that would get us to the low end?

The chassis situation at TBEI that we talked about, we expect it to be volatile, although we were encouraged by March. So there is uncertainty there. You referenced coronavirus, if we saw something like we saw in January and lost 20,000 production hours that could be another issue. The final issue that we're monitoring that we talked about is given the China shutdown, although we don't have a lot of direct exposure, the chassis OEMs, if there was another microchip issue, and we stopped getting the chassis that have been promised to us for our Vactor Elgin and other vehicle-based businesses, that could also be a problem. So all of those are baked into the low end of that guidance.

Okay. All right. Great. Thank you.

This concludes the question-and-answer session. I would like to turn the conference back over to Jennifer Sherman for any closing remarks.
