[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Thanks, Aaron. Good afternoon, everyone, and thank you for joining us. The Republic team finished the year strong by executing our strategy designed to profitably grow the business. We outpaced expectations throughout the year and deliver results that exceeded our full year guidance. During 2023, we achieved revenue growth of 11%, including 5% from acquisitions, generated adjusted EBITDA growth of 13%, expanded adjusted EBITDA margin by 60 basis points, including margin expansion in the underlying business of 100 basis points, reported adjusted earnings per share of $5.61, and produced $1.99 billion of adjusted free cash flow. We continue to believe that investing in value-creating acquisitions to further expand our business is the best use of our free cash flow. We invested $1.8 billion in acquisitions in 2023, including transactions in both the recycling and waste and environmental solutions businesses.

As part of our balanced approach to capital allocation, we returned $900 million to shareholders through dividends and share repurchases. The results we are generating are made possible by executing our strategy, supported by our differentiated capabilities. Regarding customers' zeal, our efforts to provide industry-leading service continues to drive sustained customer loyalty and organic growth in the business. Our customer retention rate remained high at over 94% and we continue to see favorable trends in our Net Promoter Score due to the value of our offerings and quality of our service delivery. We delivered outsized organic revenue growth during the fourth quarter with simultaneous increases in price and volume. Core price and related revenue was 8.8% and average yield on related revenue was 7.7%. Organic volume growth on related revenue was 40 basis points. Turning to our digital capabilities.

The team continued to advance the implementation of digital tools that improve the experience for both customers and employees. Development of our new asset management system is underway, which is expected to increase maintenance technician productivity and enhanced warranty recovery. We expect to begin utilizing the new system in late 2024. The continued operational enhancements supported by our RISE digital operations platform are expected to drive additional productivity through improved route optimization and safety performance and provide more predictable service delivery to our customers. We anticipate the RISE platform will drive approximately $100 million of total annual earnings contribution, of which approximately $65 million has been realized to date. We continue to implement advanced technology on recycling and waste collection routes. Our platform utilizes cameras to identify overfill containers and contamination in recycling containers. This technology is reducing contamination and driving incremental revenue. Moving on to sustainability.

We believe that our sustainability innovation investments in plastic circularity and renewable natural gas are a platform for profitable growth. Development of our polymer centers and Blue Polymers joint venture facilities remain on track. We are finalizing commissioning at our Las Vegas polymer center this week. Delivery of plastic flake to our offtake partners is expected in the coming weeks. Construction is progressing on our Indianapolis polymer center. This development will be co-located with Blue Polymers production facility and construction at the site is expected to be completed in late 2024. The renewable gas projects being codeveloped with our partners continue to advance. Five projects came online in 2023, and we expect at least eight additional projects to be completed in 2024. Efforts to support decarbonization, including our industry-leading commitment to fleet electrification. We currently have 11 electric collection vehicles in operation.

We expect more than 50 additional EVs will be added to our recycling and waste collection fleet in 2024. We have six facilities with commercial EV charging infrastructure with more than 40 additional sites in varying stages of development. As part of our approach to sustainability, we continue to strive to be a workplace with the best people from all backgrounds who wants to work. In 2023, employee engagement improved to a score of 86% with 90% -- 99% of employees participating in the survey. Turnover rates continued to churn lower with full year turnover improving 400 basis points compared to the prior year. As a result, we are better staffed to optimize our operations and capitalize on growth opportunities in the market. Our comprehensive sustainability performance continues to be widely recognized as Republic Services was deemed to the Dow Jones Sustainability Index for the eighth consecutive year.

Our 2023 results clearly demonstrate our ability to create sustainable value. And our ongoing investments strengthen the foundation from which we will continue to grow our business. With respect to 2024, we expect to deliver outsized profitable growth while continuing to make investments in the business to drive lasting value creation. More specifically, we expect full year revenue in a range of $16.1 billion to $16.2 billion. Adjusted EBITDA is expected to be in a range of $4.825 billion to $4.875 billion. We expect to deliver adjusted earnings per share in the range of $5.94 to $6, generate adjusted free cash flow in a range of $2.1 billion to $2.15 billion. Our pipeline supports continued acquisition activity in both recycling and waste and environmental solutions. We are targeting at least $500 million of investment in value-creating acquisitions in 2024. Our 2024 financial guidance includes the rollover contribution from acquisitions that closed in 2023.

I will now turn the call over to Brian, who will provide details on the quarter and year.

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Thanks, Jon. Core price on total revenue was 7.2% in the fourth quarter. Core price unrelated revenue was 8.8%, which included open market pricing of 10.6% and restricted pricing of 6%. The components of core price on related revenue included small container of 12.3%, large container of 8.6% and residential of 8.2%. Average yield on total revenue was 6.3% and average yield on related revenue was 7.7%. In 2024, we expect average yield on total revenue in a range of 5.5% to 6%. We expect average yield on related revenue in a range of 6.5% to 7%. Yield is expected to step down sequentially during 2024 due to relatively lower index-based pricing and certain fees implemented throughout 2023, which begin to anniversary. Fourth quarter volume on total revenue increased 30 basis points and volume on related revenue increased 40 basis points.

The components of volume on related revenue included an increase in small container of 20 basis points and an increase in landfill of 7.4%. Landfill was primarily driven by a 12.7% increase in special waste revenue. Volume growth was partially offset by a decrease in large container of 1.4% and a decrease in landfill C&D volume of 2.1%, primarily due to a slowdown in construction-related activity. In 2024, we expect organic volume growth in a range of flat to positive 50 basis points. Moving on to recycling. Commodity prices were $131 per ton during the fourth quarter. This compared to $88 per ton in the prior year. Recycling processing and commodity sales increased revenue by 50 basis points during the quarter. 2023 full year commodity prices were $117 per ton. This compared to $170 per ton in the prior year. Current commodity prices are approximately $135 per ton, which is the baseline used in our 2024 guidance.

Now turning to our environmental solutions business. Fourth quarter environmental solutions revenue was flat compared to the prior year. Adjusted EBITDA margin for the environmental solutions business was 19.7%, an increase of 250 basis points compared to the prior year. Fourth quarter total company adjusted EBITDA margin expanded 260 basis points to 29.9%, which was driven by margin expansion in the underlying business of 230 basis points. Other changes in margin performance during the quarter included a 30 basis point increase from recycled commodity prices and a 20 basis point increase from net fuel, which was partially offset by a 20 basis point decrease from acquisitions. Our full year adjusted EBITDA margin was 29.7%, which represents margin expansion of 60 basis points compared to the prior year. In 2024, we expect total company adjusted EBITDA margin to be approximately 30%.

We expect to more than overcome a 30 basis point headwind from acquisitions. Depreciation, amortization and accretion was 10.7% of revenue in 2023 and is expected to be approximately 11% of revenue in 2024. Full year 2023 adjusted free cash flow was $1.99 billion, an increase of 14% compared to the prior year. This was driven by EBITDA growth in the business and the positive contribution from changes in working capital. Total debt at the end of the year was $13 billion and total liquidity was $2.7 billion. Our leverage ratio at the end of the year was 2.9 times.

We expect net interest expense of approximately $545 million in 2024. With respect to taxes, our combined tax rate and impact from equity investments in renewable energy resulted in an equivalent tax impact of 25.1% during the fourth quarter and 24.8% for the full year. We expect an equivalent tax impact of approximately 26% in 2024 made up of an adjusted tax rate of 20% and approximately $190 million of noncash charges from equity investments in renewable energy. The expected increase in the interest expense and taxes would result in a $0.20 EPS headwind in 2024.

With that, operator, I would like to open the call to questions.

Questions and Answers

[Operator]

[Operator Instructions] The first question comes from Toni Kaplan with Morgan Stanley. Please go ahead.

[Toni Kaplan, Analyst at Morgan Stanley]

Thank you so much. I wanted to ask about margins. In the fourth quarter, I know you mentioned a couple of factors, the commodities and fuel costs. But maybe just talk about how margins were so far ahead of the guide and what factors could continue into 2024 that could provide upside to the guidance there.

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Sure. Yes. The team had a really strong fourth quarter. Lots of things went in our favor, managed the middle -- the P&L well. There were some onetime opportunities both on MSW and a very strong special waste fourth quarter on that, that we felt good with. Weather was actually very positive in the fourth quarter, which has slipped here in the first quarter of the year, so I feel great about that. And then, listen, we've got a lot of momentum headed into '23. Some of the event-based work, you can't build a budget against that, right? You've got to look at that as a potential upside, which we're going to go after those opportunities. But oftentimes, an election year, some of those jobs end up pushing and rolling forward, so we're not going to build a plan based on that outsized performance that we got in Q4, but still looking at a very positive year in '24.

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Yes. And Toni, we had mentioned all year long that we expected margin expansion to sequentially improve quarter-on-quarter. Ending the year with the highest level of margin expansion compared to the prior year. So that played out exactly as we thought. Now the margin expansion itself was a little bit stronger than we originally anticipated. But ending the year with that type of performance and the type of margin expansion in the -- over 200 basis points was in line with the way we thought it would end.

[Toni Kaplan, Analyst at Morgan Stanley]

Perfect. Wanted to ask about environmental services. Maybe just talk about what you're seeing and the different pieces there. And I think it's a little bit flattish in the quarter. So does that turn around next year?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. Most of the flatness is based on the comp. We had a really, really strong Q4 and '22 that we were covering. Listen, there is some slowdown in parts of that business, so rig counts are down, and that's part of the opportunity in there. We've had a facility that we've shut down to turn around that we're going to reopen here in the middle of the year. So that'll provide some incremental lift, and that was closed in the fourth quarter. And then we continue to -- we'll trade price over volume where we need to. So we've turned out some less profitable customers on that and feel really good about the book and the pipeline going forward.

[Toni Kaplan, Analyst at Morgan Stanley]

Perfect. Thanks so much.

The next question is from Kevin Chiang with CIBC. Please go ahead.

[Kevin Chiang, Analyst at CIBC]

Hey, thanks for taking my question and congrats on a strong end of the year there. Maybe just on the 2024 guidance, the implied kind of 30, 40 basis points of margin expansion, reported margin expansion you're guiding to. Is the way to think about how that splits between solid waste and ES, is it pretty balanced between the 2? Or would you expect one to maybe outperform the other end as you look out into 2024 here?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Yes. Look, overall, I would sit there and say that we expect margin expansion in both of the business types. We're expecting just as -- when you take a look in basis points, a little bit more on the ES side, the environmental solutions side, but it is still relatively balanced between the 2. Just given the sheer size of the recycling and waste business relative to the environmental solutions business, it will drive a majority of the overall expansion when you think about the enterprise taking this whole.

[Kevin Chiang, Analyst at CIBC]

That's helpful. And maybe just my follow-up question. Just looking at the -- your yield volume table that you provided in your disclosure. Just, I noticed the strong yield in residential volume's maybe a little bit worse than recent trend. Just wondering if you could provide some color in terms of what's happening there and if you're -- as you mentioned earlier, are you maybe being more purposeful in shedding maybe lower-quality volume to the

Benefit of yield in the fourth quarter?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. we're always purposeful in trading up price versus volume. I'd say in this quarter, there was a couple of contracts that went out to bid, that we bid a rate that we thought was going to cover our costs and give us a fair return. We lost those opportunities. And then in previous quarters, we've had some nice wins, right? And these things come in fits and spurts, so we didn't have anything in that quarter. That's really -- the combination of those two things drives the volume picture. On the pricing side, this is the manifestation of high CPI and the alternative indices over the last couple of years really flowing through our pricing, which is great to see. That's the challenged part of the yield story historically, and to see that number, we were really pleased with.

[Kevin Chiang, Analyst at CIBC]

Excellent. I'll leave it there. Again, congrats on a good sets of results there.

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Great. Thanks.

[Operator]

The next question is from Bryan Burgmeier with Citi. Please go ahead.

[Bryan Burgmeier, Analyst at Smith Barney Citigroup]

Good afternoon. Thank you for taking the question. Maybe just following up on Toni's question. I think margins have typically expanded kind of quarter-over-quarter from 4Q to 1Q. I imagine that'll be a little bit more flattish this year. Just if you can identify maybe some of the factors weighing 1Q margins or, more broadly, like, why historical seasonality might not apply.

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Brian, what I would say is that when you talk about historical seasonality, I think you have to go back before just the last several years, kind of post pandemic. I think you have to look at a broader data set there. So when we came into this year, we said this year, we thought, was going to have what we would call a normal level of seasonality. And when you take a look at what that means, that would typically -- when you look at margin performance, you would have peak margin performance in Q2 and Q3 during those summer months where you're getting some more of those seasonal volumes, in particular, on the landfill side, followed by Q4. And then finally, the first quarter would seasonally be your lowest margin performance, and that's what we've seen for decades. And so we said that at the beginning of the year, that's kind of what played out. And that's, what I would say we would also expect going into '24, based on what we see right now.

So we would expect a sequential step down in margin from Q4 to Q1. In part, you've got more winter months when you're dealing with the first quarter. As well as when you just think about some of the taxes, you have your highest burden from a labor perspective in the first quarter. And those tend to max out and then as you move through the balance of the year, again, some of those -- some more of those state and local taxes, then those basically reach their max in the first quarter. And we have weather, right? We had mild weather in Q4 of last year. We had pretty intense weather in January, where we've lost some -- certainly some hauls and some tons. Some of that will come back, but some of that will get pushed out through the remainder of the year. So that's what will lead to Q4 number that probably looks -- our Q1 number, that probably looks more flat than historically might have.

[Bryan Burgmeier, Analyst at Smith Barney Citigroup]

Got it. Got it. And then just following up on M&A, with the deals you completed in 4Q, did you provide a split -- rough split for how that is divided up between the two segments? And did you provide a rollover contribution to '24 revenue in guidance?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Rollover contribution will be about 200 basis points. From deals closed in '23, that'll have a rollover impact into '24. Just on the split from a revenue perspective, it was about $200 million on the environmental solutions of the annualized revenue acquired in the fourth quarter and about $140 million on the recycling waste side.

[Bryan Burgmeier, Analyst at Smith Barney Citigroup]

Got it. Thanks a lot. I'll turn it over.

[Operator]

The next question is from Walter Spracklin with RBC Capital Markets. Please go ahead,

[Walter Spracklin, Analyst at RBC Capital Markets]

Yeah. Thanks very much. Good afternoon, everyone. So I wanted to follow up on M&A here. A big year for you in terms of deals done, I think, $1.86 billion there acquired. And I was wondering if you could give us an update on, first of all, what the pipeline looks like going forward, particularly relative to such a large year this past year. And then second is in terms of integration, will you be focusing a bit more given how big the year was in 2023 on integration and perhaps assess or put a little bit on -- touch a little bit on how that integration is going? Or do you see room and capacity to continue at a fairly heady space -- pace here in terms of M&A for 2024?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. Listen, we look at two things. Obviously, the strategic fit and the financial return on any type of deal, and we're going to stay disciplined on both of those things. Are we the natural owner, and does it meet our expectations in terms of cash on cash returns. And then we do think about our ability to absorb it. And listen, we have a lot of capacity across the enterprise. We wouldn't necessarily do a couple of big deals in the in the same part of the country at the same time because the local team does play a pretty strong role in that day-to-day integration activity. Last year was the product of our normal tuck-ins, which are -- we've done forever, and those are very value creating.

It's hard to do those deals poorly because we've done it for so long. And then some nice kind of medium-sized deals. We built the plan, right, not anticipating that those medium-sized deals are going to be there. Not that we're not pursuing it, but you just don't know when they're going to move or when they're going to come. So that's predicated on a step-down in our expectation this year for what we've done. It's not because the pipeline is weaker. Pipeline is strong, but we never know exactly what we're going to close, and we're going to stay disciplined.

[Walter Spracklin, Analyst at RBC Capital Markets]

Got it. That's great color. And just for my follow-up, turning to recycling. I know your Las Vegas polymer center opened in December. Can you talk a bit about the build out on that -- on the polymer center? And I don't know if you've had enough time now to assess, but do you see this as a better investment than kind of EPR -- or not better, but how do you -- how does that compare to EPR projects in terms of the return profile of that one?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. We're very satisfied with both the execution and the return. We're pretty conservative in terms of our financial modeling, leaving ourselves room and we feel very good about the demand in the marketplace. We could have sold our Las Vegas five times over at front. And the pricing expectations are ahead of what we modeled. So the returns are going to come in, again, ahead of our expectations on that front. And that's certainly given us confidence, as we talked about in the prepared remarks, to go to Indy, and then we're planning on at least two more across the country.

[Bryan Burgmeier, Analyst at Smith Barney Citigroup]

Fantastic. Appreciate the time.

[Operator]

The next question is from John Mazzoni with Wells Fargo. Please go ahead.

[John Mazzoni, Analyst at Wells Fargo & Company]

Thanks for taking my question. Maybe just a quick one on pricing. Could you just remind us how the restricted book will layer through '24, especially with sort of the lag effects in CPI?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Yes. One thing, as I mentioned with respect to the cadence from a pricing perspective in my prepared remarks, is we do expect a sequential step down in the level of pricing throughout the year, primarily due to the impact that, that index pricing will have. So again, we expect this to report the highest level of average yield in Q1 and the lowest level in Q4 with a step down in between. Just to give you a little bit of perspective, when you take a look at the two primary components that may make up our basket that are related to some sort of index, one being headline CPI and then the other being the alternative indices.

And when you take a look at headline CPI, right, it saw its peak in June of '22, and has been stepping down sequentially since. Water sewer trash and garbage trash saw peak levels in August of '23 and have been stepping down since then. Now that said, the water sewer trash and garbage trash still remain at elevated levels. Water sewer trash, the recent print was 5.5% and garbage trash was 6.4. So we're still pretty pleased about the level, but it is going to sit there and step down just due to the math.

[John Mazzoni, Analyst at Wells Fargo & Company]

Great. And maybe for a quick follow-up. Could you just talk to the strength in small container, especially with the 11.2% yield? It seems like that's kind of above the average. And any other thing you're seeing within that kind of end market and any other commentary around anything different that you've done compared to peers?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Sure. Yes, we rolled out some new technology around AI, which helps us spot contamination and also helps us assess overages, when the containers are overfilled. And that certainly contributed to the small container performance. Again, underlying pricing was great, but that put it on top. And that's why we talked about our '24 number. We expect to anniversary that in the second half of the year, so that will come down a bit.

[John Mazzoni, Analyst at Wells Fargo & Company]

Great. Thank you.

[Operator]

The next question is from Michael Hoffman with Stifel. Please go ahead.

[Michael Hoffman, Analyst at Stifel Nicolaus]

Hey, guys.I've always challenged for that Stifel, Stifel, Stifel, whatever. So free cash flow and the guide, it is at about 7% in the midpoint versus the top line's at 7.9% and EBITDA is at 9.1%. I'm presuming we've got higher interest expense and probably higher cash taxes, because you're not counting on bonus depreciation being retroactively reverted back to 100%. Is that how I think about the bridge between the growth rates through the P&L?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

That's correct, Michael. If you just take -- taxes alone, when you take a look at two components, so one, we are assuming that the current loss stays in place, which means bonus depreciation will sit there and have a further headwind '24 compared to '23, combined with the settlement we had with the IRS in '23, where we received $20 million of cash back to a matter that dates back to 2017. Combined, those two create a $45 million headwind in cash taxes. That alone is a 2.3% headwind to year-over-year growth on the free cash flow. So you just take taxes alone and you'd sit there and say you'd be kind of 9.5% growth in free cash flow were it not for the impact of taxes. Interest, to your point, would just be considered headwind.

[Michael Hoffman, Analyst at Stifel Nicolaus]

All right. And that was what I was trying to get at is the underlying cash growth is there and you've got some timing issues related to what we just discussed. Okay. On margin

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

And Michael, to that point, from an underlying business perspective, the growth in free cash flow is double digit.

[Michael Hoffman, Analyst at Stifel Nicolaus]

Right. Okay. That's, I think, important. And then on margins, I think there's another sort of message to potentially to be drawn out. So your pattern in your solid waste business, given the sheer scale of managing price costs, as you're being pretty ratably able to deliver all 30 basis points, so if the whole company is doing 30 and you've got an M&A headwind and, actually, environmental comes in as a nice add in ES, but it's probably pretty dilutive. So how do we think about that ES dilution? It's much better structurally ex that dilution is what I think, which.

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Just to give you the middle perspective, if you look across, right, both business types, we're expecting 30 basis points of dilution from acquisitions. And we would expect dilution, from an acquisition perspective in both recycling and waste and environmental solutions. If you're looking at the underlying business itself within ES, we're expecting over 100 basis points of margin expansion in the environmental solutions business due to the underlying business itself.

[Michael Hoffman, Analyst at Stifel Nicolaus]

Right. And about 30 in solid waste and then a net in the total company dilution, but it's greater in ES than it is in solid waste. It's just one size of the deal relative to the base?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

That's correct.

[Michael Hoffman, Analyst at Stifel Nicolaus]

Yes. Okay. I think that's important to draw that. You're still on that track of 25% or better margins at ES, ex acquisitions and the acquisitions will then contribute to that as you integrate them?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes.

[Michael Hoffman, Analyst at Stifel Nicolaus]

Yeah. Okay. Cool. Thanks.

The next question is from Noah Kaye with Oppenheimer & Company Inc. Please go ahead.

[Noah Kaye, Analyst at Oppenheimer &]

Thanks. Jon, Can you talk to us about this new asset management system that you're putting in place? What are you functionally doing? And where does that ultimately show up in the P&L? Is it maintenance and repairs? What kind of savings are we talking about with this new the system?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. It's really with the RISE platform. Think about digitizing our operations, from our logistic operation all the way through our fleet and how our drivers operate every day. This brings this to the maintenance shop. And so now rather than moving paper around, right, when the driver does their vehicle condition report before they take off in the morning, that digitally flows and is recorded into the maintenance organization. So they're dealing with tablets as well. So they're getting out of the paper-based business. And a big driver of that -- there's a productivity benefit to that for sure, but then there's also the warranty recovery element of that. Because when you're chasing paper, that becomes a very manual process. When you could do this digitally, it allows you to quickly understand what warranty is available, are you fully claiming all the parts that are warranty-eligible and allowing us to get full recovery.

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Yes. When you think about the linkage, so a couple of years ago, we started on our journey of modernizing our core systems, and that started with our general ledger and procurement systems. This is an extension of that. So the asset management system will be directly linked and integrated on a common platform with our procurement system. So now you can sit there and say, from the point of PO all the way to putting something on a truck, you can sit there and you can track that part. So to Jon's point on warranty management, this is something, before, we had to do very manually, which means that we had a lot of leakage in the system. Now we feel very confident that we're going to get every single portion of that warranty that we're entitled to.

[Noah Kaye, Analyst at Oppenheimer &]

Very nice. Just a quick housekeeping one. You already detailed the expectations for yield-ins through 2024. But just picking up your comments around weather, tough volume comps for 1Q and you just mentioned the weather flipped to be a little bit of a drag here to start. We all felt that cold. So how do we think about kind of the volume trends Q-to-date and how that trends through the year?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Look, I mean, the good news, right, is that while January, we did experience quite a bit of weather. We've seen most of that volume return. Not a total recovery, but we saw what we would've expected in February so far to date. Look, we're guiding to flat to 50 basis point positive. Q1, may be kind of the low point of that because of the weather. But I would think of it relatively ratable, that type of cadence throughout the year.

[Noah Kaye, Analyst at Oppenheimer &]

And in an environment where your yield is decelerating year-over-year at a pretty, pretty shallow step down, you can get the March expansion that you're looking for without a lot of volume contribution. So you let the volume of the upside to where margins can go. Is that the basic takeaway?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Correct.

[Noah Kaye, Analyst at Oppenheimer &]

All right. Thanks very much. I will hand over.

The next question is from Stephanie Moore with Jefferies. Please go ahead.

[Stephanie Moore, Analyst at Jefferies Financial Group]

Hi, good afternoon. Thank you.

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Hi, Stephanie.

[Stephanie Moore, Analyst at Jefferies Financial Group]

Hey, there. I wanted to touch a bit on maybe the underlying macro environment, probably a decent follow-up to the prior question. You called out some weakness in the quarter on financials, C&D volumes. I don't think any of us would be really surprised to hear that. But maybe any other areas you might be seeing weakness or other levels of strength of the opposite? And then what is the kind of the underlying macro assumption embedded in the 2024 guidance?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. I think the picture is mixed. So again, we're planning on having a strong year. If you think about the direct things, we talked about weather, certainly housing, interest rates being high, mortgage rates being high, housing activity is certainly a byproduct -- or depressed housing activity is a byproduct to that. So we would have hoped for a quicker recovery there, both for our business and because we need more homes in the United States, but we think that'll be more delayed towards the later end of the year, so we're not planning a robust recovery on that front. And then if you think about the other macros, the manufacturing, I think, is a mixed picture.

We see pockets where, while we're winning business, there are some service declines in certain subsectors of manufacturing, but other places, in terms of remediation projects and other things have been very, very strong. PFOS has been a nice contributor to the business in 2023, and we've got a good pipeline in 2024. And then the background, we have two wars going on, right, one in Israel, one in the doorstep of Europe. Credit card debt is high with consumers, so we have a cautious kind of macro perspective on that, but the underlying demand signals for our business are largely positive.

[Stephanie Moore, Analyst at Jefferies Financial Group]

Great. No, that's helpful. And then you touched on this a little bit, but if you could kind of walk through kind of what you've seen from the cost inflation standpoint clearly getting better, but some of those clear headwinds that we saw through most of 2023, kind of how those are trending now to start 2024.

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes, certainly stepping down operating labor, clearly stepping down year-over-year. Transportation is stepping down. Maintenance has been a little bit stickier and most of that is the fact that we're growing and we're driving a fleet that's aging just because the supply chain is still a little congested and we're not getting all the trucks that we wanted. And it's really been a three-year phenomenon in that front. So we're going to catch up some in this year, but we're not going to fully catch up on that. And all that is when you're driving a 12-, 13-year-old truck, right, with its kind of a peak cycle in terms of its maintenance versus a new truck that has relatively high-warranty recovery, and so therefore, very low maintenance cost, that's going to show up in the underlying maintenance bucket. So that spend will be, we think, elevated throughout the year. We hope we do a little better, but we'll see.

[Stephanie Moore, Analyst at Jefferies Financial Group]

Okay. Thank you so much.

[Noah Kaye, Analyst at Oppenheimer &]

The next question is from Jerry Revich with Goldman Sachs. Please go ahead.

[Jerry Revich, Analyst at The Goldman Sachs Group]

Yes. Hi. Good afternoon, everyone. Yes, I would just love to continue the conversation on the cost side. I mean, really impressive in the quarter. Your cost per unit were up just 1% year-over-year. So I'm wondering where are you starting to see deflation. It sounds like the tailwind from better equipment availability is still in front of us, so I'm wondering what's gotten better for you folks already in the fourth quarter number. And then Brian, I'm wondering if you'd just put a finer point on the comments that you made about yield slowing over the course of the year on comps. Do you expect to exit the year with price cost spread still favorable fourth quarter versus fourth quarter?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Yes. Yes, Jerry. So Jon mentioned one of them already. Our labor has continued to improve, right, really throughout the year. And in part, that's just due to a reduction in turnover, right, that we've seen. And so again, when you just take a look at the impact that turnover has, there's a hiring cost of bringing someone else, as well as there's a productivity impact. A newer driver just tends not to be as productive as those that have some tenure. And so we're starting to see, as the turnover rates have come down, we're seeing that kind of come through that labor line item, which has had a positive impact. So I would say that's where we've seen some of the biggest improvements. Together, we mentioned throughout the year, some of the impact that transportation cost it had.

These were things where we had multiyear agreements, they came up for renewal in the second half of '22. And we said that we took some pretty big price increases and that they were going to comp out in the second half of '23 and we've certainly seen that. So I would say those are some of the tailwinds we've seen it from a cost perspective. The maintenance has stayed relatively sticky in kind of that 7% to 8% type cost increase range year-over-year. To your question just on the price/cost spread, I would say there's -- we expect the biggest or the most positive impact between that in the first quarter. We expect that to modulate throughout the year, but still, price exceeding cost by the time we exit 2020.

[Jerry Revich, Analyst at The Goldman Sachs Group]

Okay. Super. And then nice progress on a $100 million efficiency program. How much progress did you make in '23 specifically and the remaining $35 million of productivity improvement? When do you expect -- how much of an improvement do you expect in '24 relative to that remaining $35 million?

[Brian M. DelGhiaccio, Chief Financial Officer, Executive Vice President at Republic Services]

Approximately about $10 million or the remaining $35 million. Approximately about $10 million or the main $35 million.

[Jerry Revich, Analyst at The Goldman Sachs Group]

Thank you.

The next question is from Tobey Sommer with Truist. Please go ahead.

[Jack Wilson, Analyst at Truist Financial]

Yeah. Good evening. This is Jack Wilson on for Toby. Can we double-click on sort of the state of the fleet and specifically fleet electrification in the long term and sort of where you see that going?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Sure. We've mentioned in the prepared remarks that we have 11 right now, we'll have -- add 50 to that this year. We'll be at several hundred next year and climbing our path. That's going to start in residential, and then it will move into small container over time. And we've got a really thoughtful strategy in terms of how we roll that out. I mentioned the infrastructure side of that as well, it's not just a truck, right? It's a system. So you need to understand the infrastructure. You need to understand the incentives. You need to understand the customer's willingness to pay for the vehicle. And if we feel that the trucks that we've had delivered out of our partnership with Oshkosh, those trucks are working very, very well. So we're excited to see the next 50 come into the fleet.

[Jack Wilson, Analyst at Truist Financial]

Okay. And then just as a follow-up, can we sort of dig into the moving parts of volume? Are there any sort of specific geographies or market segments that are especially volatile or changing?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

No, I mentioned the housing piece, large-container temp, but that's been certainly soft as we're not putting up as many new houses as we need and even for movement, people are kind of keeping their existing mortgage rates and are reluctant to move. And oftentimes, we see move -- we see remodeling activity or other ancillary opportunities and large container temp, and that's been muted. We don't think that will last forever here, but we're planning on a relatively benign year this year, looking to 2025 to see that accelerate.

[Jack Wilson, Analyst at Truist Financial]

Thank you very much.

The next question is from Tony Bancroft with Gabelli Funds. Please go ahead.

[Tony Bancroft, Analyst at Gabelli Funds]

Thanks for the question. Nice job on the quarter. Just some more color maybe. You mentioned PFOS remediation. Could you just maybe talk about what is going on currently at your landfills or whatever you're doing regarding PFOS? And what could that -- maybe just a general idea what could that business look like opportunity-wise going forward?

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. We think we've got a very compelling offering for customers in an end-to-end solution. So we can hand all the way from the assessment to the frontline remediation with doing our field service work and then a range of disposal options on the back end, whether that's into hazardous landfill, whether that's in deep well, some of that waste can be profiled. We're going to put into a solid waste landfill as well, and you're seeing some of that flow through our special waste.

So that's measured in the tens of millions if you look at last year. This year, it'll be the high end of tens of millions or potentially tipping into a nine-digit number in terms of revenue. So this is a real growth opportunity for us. And this is all mostly people self-selecting in advance of the EPA regulations coming down as well as some of the Department of Defense work that's been accelerated on that front. So we feel like our national footprint positions us well to -- in our strategic accounts organization, positions us very well to serve customers on this issue.

[Tony Bancroft, Analyst at Gabelli Funds]

That's great. And then maybe switching to trucks. You talked about what's going on with EVs and the amount of deliveries coming, which sounds great. Any issues with maybe on just traditional trucks and EVs on supply chain, getting those deliveries? And then just to piggyback on that one, if surprises -- you see any surprises in EV performance. You hear and read a lot of things about how it's performing. Obviously, you're pretty well situated just based on the routing system. But just some real-time color on how those -- I guess there's only a few right now, but that's going to be growing, and I'm sure you've done a lot of testing.

[Jon Vander Ark, President, Chief Executive Officer, Director at Republic Services]

Yes. The supply chain is -- again, we're probably getting about 80% of the trucks we want over the last couple of years. And that includes the rollover from the previous year, right? So we're not continuing to fall way behind, but we haven't fully caught up yet either. But keep in mind, we've grown a lot. We're coming off our third straight year of double-digit revenue growth on that. So as we grow and do these acquisitions, that creates more demand and need for new trucks. So we see the supply chain improving. I think we'll get -- we'll shorten that -- we'll shrink that gap as we exit '24. I don't expect that we'll close that gap until 2025 on that front.

And then the EV specifically, the McNeilus truck is the first purpose-built refuse truck ever and it's electrified. And that truck is driving a full route. Most of the other EVs that we've piloted, that you spend the first 60 days with a lot of software issues that you're working through. We've been really, really surprised by the performance level and the uptime of this vehicle. We're working through some bugs. We're still in a test-and-learn environment, but really promising in terms of what this is going to be able to do to operate at scale with EVs.

[Tony Bancroft, Analyst at Gabelli Funds]

Thank you so much. Great job.
