Tony Bancroft
Okay, we’ll jump right in to our next company. We’re — it’s a pleasure to have Mr. Ed Egl here today, who is Director of Investor Relations at WM. WM is based in Houston, Texas. It’s the largest waste service provider in North America, with the biggest landfill network. Ed joined WM in 1995, and has been in his current role since 2014. WM has 420 million shares, trades around $160 for a $66 billion market cap and $13 billion of net debt.
Ed, welcome. Can you hear me?
Ed Egl
I can, Tony, thanks for having me here. Can you hear me?
Tony Bancroft
Yes, loud and clear. Thank you so much for being here today.
Ed Egl
Well, thanks for having me.
Tony Bancroft
Yes, it’s great to hear your voice, and looking forward to jumping into this. So, maybe before we begin, Ed, can you just give us some background of Waste Management, sort of set the stage, and talk a little bit about what you do and maybe how you’re different from the rest of the industry.
Ed Egl
Sure, definitely can do that. And I think I need that picture of myself there, a long time ago when that one was taken. But — so, it’s — WM, as you mentioned, is the largest North American [server] [Ph] waste environmental solutions provider. We service almost all 50 states in the U.S., and almost all the provinces in Canada. We have the largest landfill network, as you mentioned. We also have the largest recycling network across North America. So, we are very much focused on materials management and finding the best use for those. We are approaching $19 billion in revenue, and approaching 30% EBITDA margins over the long-term, so a very strong profile. And we can go into details of any of those lines of business, but we service all collection, commercial, industrial, residential, landfill, recycling, organics, all kinds of different solutions for all of our customers.
Tony Bancroft
That’s great, thank you, Ed. And maybe you heard me stumbling over WM a few times, hard to get — it’s hard to — I’m working on it. But you see it, and it might not be up now, but in the cover presentation you see WM as your symbol. And I know you use WM, but now I think everyone is starting to know you as WM.
Question-and-Answer Session
Q – Tony Bancroft
Can you talk to us why you sort of shifted to WM versus Waste Management, what the driver of that was?
Ed Egl
Sure. As you probably know, WM hosts the Phoenix Open, has been doing it for many years. And as part of that we have what we call, the Sustainability Forum. And we bring in leaders — thought leaders across the globe, basically, to come in and talk to us about the future of sustainability and where the world is going. And a couple years ago, we had someone challenge us that we’re not just waste management, we don’t just provide waste services; we provide environmental solutions to companies. And I think that’s really where our name change comes into play, right. We’re doing much more than picking up waste; we’re doing organics, we’re doing recycling, we’re doing all kinds of things to provide a better future for tomorrow. So, it felt appropriate for us to drop the waste piece of it, and just go with WM.
Tony Bancroft
Yes. And I guess I did a pretty good job for myself to get us into the next question here, it sort of segues well, right, for — so, your renewals business and recycling, you had some pretty good news in the last quarter. Could you talk about that capital program that you announced?
Ed Egl
Sure. So, we had two pieces of it. We had the renewable energy piece, and we had the recycling piece. And we’re going to spend about $275 million each, in 2022, on both of those. And they’re a little bit different, so I’ll start with the renewable side. We’re looking at building 17 new renewable energy projects, taking the methane that’s naturally occurring in our landfills, and converting it into renewable natural gas. We operate the largest natural gas fleet in North America, not just in the waste space, but across all industries. And that allows us to recoup a benefit, the RINs credit, which I’m sure we’ll talk a little bit about, because we’re fueling our trucks with that.
So, it’s a pretty good economic return for us, on average about three-year payback for those investments. We’ve been doing this for over two decades, right. If we go back and look, we have 130 projects today on our landfills; most of them are methane to electricity. But now, we’re starting to move to the renewable natural gas side because we’re able to fuel our own fleet and generate that RIN credit forward. So, it’s a great investment story for Waste Management, taking something that was really a cost for us, right, as part of our obligations to monitor all our air emission — quality emissions, we have to capture the methane and fire it, generally, is what we’ve done in the past.
Now, we found this opportunity to create some revenue and earnings from this, and do something that’s better for the environment. So, it’s a big win across all the board.
Tony Bancroft
And maybe talk a little bit about why now, what is the — what’s changed? Are there catalysts that’s changed, why you seem — seems like most of the industry is heading towards this, is there something that happened to waste management or, obviously, I mean fuel prices are changing, but could you sort of talk about that, the rationale?
Ed Egl
Sure. I don’t there’s any one catalyst. Like I said, we’ve been doing this for two decades now. We have the expertise on how to do this. I think really what it comes down to is there is an opportunity for continued growth in our business, right, from an organic perspective. As you know, we closed on the Advanced deal back in 2020, and we finally fully integrated it, past the one-year anniversary, in October of last year. And doing large scale acquisitions become more difficult for us, right. And we could still continue to do tuck-in acquisitions, but in order to get some good organic growth out of the business; this is an opportunity for us that we saw to continue to grow that business.
So, I don’t think there’s any one catalyst. We’ve been doing this, again, we have four projects that we built over the last six or seven years, and this is just a continuation of that. And it’s going to provide some long-term growth that otherwise we may not be able to see from an acquisition split, right. Doesn’t mean we won’t do acquisitions, but it’s an opportunity to grow organically.
Tony Bancroft
Natural fit; makes sense. And could you remind us again, I think you mentioned it, but what is — how much of your revenue is the renewables right now, and where could, potentially, that go to, at the double-digit? Where could that be?
Ed Egl
Sure. So, it’s about 1% to 1.5% of our business today, so still a tiny piece of it. As we continue to grow the portfolio it’s obviously going to grow. But we expect our normal organic revenue growth from our collection and disposal business to grow as well. So, it’s — it might grow a little bit faster over the next couple years than our organic revenue growth because we have such a focus on those 17 projects. But where it goes, it’s hard to say. Will it be 20% of our revenue? I’m not — I don’t think so, but I think it’ll continue to grow, and maybe get up to 3% to 5% or something like that; it’s just hard to say.
Tony Bancroft
Sure. And maybe switching now to the recycling piece, processing fees, you’ve done a really good job of shifting the business. Maybe you could just give us a little — for those not as familiar, give us a little background on that, and maybe sort of update us on where you are now on the processing side?
Ed Egl
Yes, this goes back many years ago, and there’s couple of things. You have the Chinese Green Fence, and the Chinese National Sword, basically, where the Chinese government is really shipping most of our cardboard overseas. The Chinese government decided they didn’t want to take in the world’s garbage, right. So, there’s a lot of contamination in some of these bales. I’m not saying that we were doing it, but a lot of other companies have a lot of trash in their bales, upwards of 20%. So, the Chinese government decided to put in a restriction that you could only have 1% to 2% of contamination in there. When this was going on, it was causing the market pricing for commodities to decline significantly. And we were upside-down in a lot of our contracts.
So, we had contracts where we would guarantee rebates back to our customers, but we were selling the commodities for a lot less than what we were guaranteeing to the customer. So, we took at step back at that point in time and said, look, we need to share in the risk of the commodities, and put in kind of what we call floor-based pricing, right. So, we’re going to charge customers a processing fee plus a return on invested capital before we rebate anything back to them. And as long as the commodity prices are above that level we’ll rebate it, typically call it 80-20, where the customer is going to get 80% of the rebate, and we get 20% of the rebate, so we share in the upside potential, but we’re protected on the downside.
That’s really kind of the crux of it. We’ve gone through most of our contracts, and luckily, over the last several years, we haven’t gone to that low level just yet, but we feel we’re protected on the downside if commodity prices come down. We don’t think it’s necessarily going to be in the near-term if commodity prices come down, because we’re very bullish on the recycling outlook. There’s, if you look at most CPGs and other companies, they’re looking to increase the amount of recycled content that they put in their products. So, there’s going to be a demand on the back-end of our recycling facilities to see an increased amount of recyclables flown through the plants. So, we think we’re in a good spot just continuing to see reasonably priced commodity values.
Tony Bancroft
And I think I know the answer to this, but I’m going to ask anyway.
Ed Egl
Sure.
Tony Bancroft
Is there — now that these were implemented in — on a down cycle essentially.
Ed Egl
Yes.
Tony Bancroft
More the beginning of. Is there buyer’s remorse or is that just not relevant, you don’t want to play in that game anymore? Well, just maybe –?
Ed Egl
So, I’m not sure I follow, well, on a buyer’s remorse side.
Tony Bancroft
Or like if — would you not — would you want more exposure now with that?
Ed Egl
I don’t think so. I think it’s still — we’re in the sweet spot here, right? We still share any upside but we’re also protected on the downside. So, I don’t think there’s buyer’s remorse, so we’re doing everything we can as part of the investments that we’re making, part of it’s automation. And I’m sure we’ll talk about automation in a minute, but part of it is to move into new markets as well, right. So, we think there’s opportunities to continue to grow the recycling business.
Tony Bancroft
Yes, and that’s really great segue, maybe we can talk about, it’s another topical issue with labor, and you’ve talked about it in the last couple quarters of absenteeism and just the resignation, can you talk about how labor is impacting your business and what that means, and then maybe talk about automation is offsetting that or you’re benefiting from that?
Ed Egl
Yes, so as you can imagine, the jobs our drivers have, and our technicians, and the people that work in the recycle facilities, they’re tough jobs, right, they’re not easy by any stretch of the imagination, I have a ton of respect for everything they do. I know I couldn’t get on the back of a truck and pick up garbage. So, what we saw in Q3, and Q4, we proactively in June and July increased wages for our drivers, we saw some of this coming down the road here. And I thought it would be a good opportunity for us to try to retain our drivers. But in Q3, and Q4, what we started seeing is a lot of COVID, absences. And I think we mentioned on our fourth quarter earnings call that we saw peak got twice as high in Q4 than we did in Q3. And what that caused is to have a lot of overtime hours, and to have as we’re hiring drivers, a lot of training hours. And that caused labor to go up significantly in Q3.
I think we said about 7% inflation in those categories. I think starting in a New Year we’ve seen COVID absences kind of come down, it’s not anywhere near where the peak is. And we’ve seen some of those training hours turn into productive hours. So, the people that we hired are now on the road, picking up garbage, picking up recyclables. And moving more into productive hours, over time is coming down a little bit because you don’t have as many absences. So, I think we’re seeing that shift improve a little bit. I do think the carryover impact of the wage increase that we gave you in July will follow through the first two quarters of the year, until we anniversary that piece of it. But we’re doing everything we can to make sure that we do everything to attract and retain the best workforce that’s available out there.
Tony Bancroft
And maybe talk about the jump into automation, I mean Jim sort of walk the dog on what the offset will be that 5,000 to 7,000, they’re naturally going to attract and then automation comes in, what can off — how much can that offset?
Ed Egl
So we’ve talked a lot, you said 5,000 to 7,000 positions, the more detailed example that we have given of course on the recycling side where we think we get about 1,000 positions out. And again, we’re not going through and terminating employees, these are high turnover positions. And I want to make sure everyone understands that a lot of these positions are through a temporary agency, they’re not employees of WM.
So, we have 48,000 employees today, you’re not going to see 43,000, by the time four years from now, it’s really the high turnover positions that are difficult to find and fill. So, as those positions turn over, we’ll be able to not hire them back and use technology. So, we said about $60 million to $70 million of labor savings is going to come from the investments in technology and reducing the workforce by about 1,000 positions in the recycling side.
We have opportunities to also improve our residential line of business where we have still about 2,000 plus rear load routes, which means we have a driver and one or two helpers on the back of the trucks. So, can we shift that to an automated side loader, where you have one driver who’s using a mechanical arm to pick up the trash and recyclables and eliminate the two people on the back, I mean, that’s a safety benefit to us, right? The most accidents occur when you’re on the back of the truck. And you have soft tissue issues, you have back issues when you’re picking up trash and trying to throw it into the back of the hopper. So, you’ll see some improvement there. But you also see some productivity improvement. So, I suspect you’ll see some savings in labor there. And then the other piece that we’re looking at is potentially high turnover positions and dispatch where we can use technology to automate some of our routing structure to do things more dynamically. So, all those together over the next four years or so we should see the headcount that Jim was mentioning.
Tony Bancroft
Yes, and I assume there’s probably more to go, could you mean this, is it or is there more, I mean I’ve heard you talk about sort of doing route optimization, there’s probably a lot of productivity that can come out of this. I mean, in the end game, I guess you could have self — using self driving vehicles, I realized that’s probably far off but where could this go, I mean how automated and how much AI could you use?
Ed Egl
Yes, I think I joke around with people sometimes I think Jim wants to have a chatbot for IR. So, get rid of me and have you guys kind of talk to a chatbot. But I don’t know we will ever get to that point, hopefully not for my sake. But as far as automation look, I think you’re right. At some point in time, will it be automated garbage trucks? I’m not sure. But I do think you’ll still have a person inside that truck might not be driving it for the most part. But it’ll be — you’ll have people in there just be a different type of job at that point in time. We’re not looking to get rid of employees in any stretch of the imagination. We just want to make sure that those high turnover positions were able to serve our customers the most efficient way. There could be more coming down the road. I just don’t see it right now, right. Yes, you talked about automation on the routing structure, that’s something your dispatchers will look to maybe have fewer jobs in the future, from the high turnover positions. But again, it’s not going to be a massive layoff of employees. It’s just going to be through natural attrition.
Tony Bancroft
Yes, I mean because your OpEx is in the low 60s, or somewhere around there. I mean, could this like be a material like, could you catch you in the 50s? I mean, what could this — where could you see this going?
Ed Egl
Yes, we haven’t set any targets out there. But look, if we’re at 60 to 61, right now, and you’re going to talk about again, if you have $60 million to $70 million for 1000 positions, call it so called 65,000 per employee at the midpoint times 5,000 employees. And we get a pretty big number at that point in time, right? But it’s not going to be, you’re not going to see it overnight, it’s going to take time for us to get there. So, I think one day in the future, you’re going to look at and go, wow, it is doing a lot better because OpEx is a lot lower and EBITDA margins are lot better, it’s just going to take time to get there.
Tony Bancroft
Yes, more scale advantage. Maybe switch to another topic, pricing and inflation. Sort of what are you seeing out there, how is pricing going with the inflation environment?
Ed Egl
Yes, I think it’s most customers understand the pricing environment we’re in today, right, and you can’t pick up the phone or you can’t look at a newspaper or go to a grocery store or gas station for that matter to see the inflationary impacts across the businesses. As long as we’re providing the quality customer service that our customers come to expect, they understand that the pricing is going to happen, right?
Our businesses in two components of pricing, right you have our 40% of our business, that’s tied to some kind of index, whether it’s CPIU or water sewer trash, something like that, that you’ll see reset about 70% of our staff at, 30% of the back half. And there’s usually a 12 month look back. So, you’re not going to see a full impact of CPI on those contracts till you get to the later half of the year and into 2023. But the open market piece is the remaining 60% is the piece where we’re able to go out there and recover our cost of inflation that we’re seeing in our business. And it seems to be going fairly well so far.
Tony Bancroft
We have, Ed can you refresh us, do you have a gasoline surcharge on the 60%?
Ed Egl
Yes, we have a fuel surcharge on all of our customers, yes. And so, to explain a little bit, there’s generally a one quarter lag in the recovery. So, what happens is our commercial customers are generally built one month in advance, and our residential customers are built three months in advance. So, for example in December, we build our commercial customer, our residential customers for the first quarter, and fuel prices rose during the first quarter, I suspect we’re not going to have an exact match. So, there could be an EBITDA impact. But over the long-term, we expect our fuel surcharges to cover the changes and fuel costs so that we don’t have an EBITDA impact to our bottom line. What you will see though, is margin impact, right, because as fuel costs rise, our fuel surcharge revenue goes up. With no EBITDA impacts, you’re going to have a margin compression a little bit there. But we should fully recover our cost increase over a 12 month period.
Tony Bancroft
Yes, along that line on the RINs that you’re going to — did you give a number to the world about what you expect to generate and hide, you’re going to flow that through to P&L when received or when accounted for?
Ed Egl
So, it’s right now for 2022, we expect about $3 of RIN price, which is kind of where it is hovering around right now. The 17 new projects we modeled at $2 RIN prices to be conservative and as we sell RINs, when you see it flow through the P&L, we’re generating right now about 3.4 million MMBtu’s of natural gas. And it’s like 11.7 times for every one RINs.
Tony Bancroft
Just give me a number?
Ed Egl
We said it’s going to be flat basically year-over-year this year.
Tony Bancroft
But what’s the total number? I don’t have the 10-K in front of me.
Ed Egl
Yes, we don’t we haven’t talked publicly about all right.
Tony Bancroft
All right, thanks. I feel like I’m in the morning meeting. This is — never — back to — maybe back to pricing, you’re in this environment with extremely be able to price, but then your churn rate is at all-time low. You can you sort of walk the dog on what’s the dynamic there? How far can you price before you start seeing some issues with churn?
Ed Egl
Yes, I don’t think we’re looking at it that way. Right churn. Most people think that churn people leave because of pricing, it’s usually people are going to leave us because of a service failure, right? We either leave the trash on the ground, we miss pick up, we have a billing issue, something like that, that gives them reason to look at our invoices.
As long as we’re providing a quality service and we look at the customer lifetime value. I think that’s more important than really the pricing aspect of it. Now, if we’re going out there giving 100% price increase or something absurd like that, we have people look at pricing, right, and there’s going to be a subset of customers that look at pricing when you give them a 5% price increase. They want to negotiate it down a little bit. But for the most part, I do think that our customers understand, we’re trying to get churned as low as possible by looking at that customer lifetime value because that’s customer stay with us longer and it’s better for us, but more profitability. And it’s pretty expensive to bring on a new customer, right? There’s a lot of things that have to go into bring it on a new customer and when you lose customers at a churn of you know, 9% or so call it, they’ve been around with you for 11 years. They’re pretty high price, right, because they’ve gone through eight pricing cycles. And you bring it on generally new customers at market rates. So, that change there is really what drives the difference between our core pricing deal. It’s that next churn.
Tony Bancroft
Yes. Obviously, you have some pretty serious algorithms that I’m sure you’ll deal with that?
Ed Egl
We do.
Tony Bancroft
Yes. What about any in this? It’s in the march. What are your — what are you seeing as far as out there with inflationary pressures? What’s your business actually seeing right now? Any thoughts in the second half or?
Ed Egl
We said about 4% to 5% for the full year inflation. We feel obviously, is one that’s a little bit higher than that, but we think we’re covered because of the fuel surcharge. I do think that I mean, I’d mentioned on one of our prior conferences that we’re still confident in our outlook for the full year, which was flat to up 40 basis points of EBITDA margin, even though we are seeing more pressure from the fuel side; still kind of early, right. We’re two months in and we closed March just yet. But we’re looking at to see what happens in your original guidance assumed down about 100 basis points in the first half and 100 to 140 in the back half to get us flat to up 40. So, I think we’re still comfortable, comfortable with that range right now.
Tony Bancroft
Maybe we can switch over to volume, your outlook shows relatively mild volume I guess is the right way to say it, but any scenarios that you can see in ’22 where we might get a boost in volume, anything you could talk about?
Ed Egl
Yes, I think there’s opportunities on the landfill side, on the federal government, thinking of the spending bill done to get the infrastructure spending going, that benefits all the waste players out there. So, there are opportunities, special waste, C&D construction. All of those areas seem to be pretty good and then what we expect to get our normal kind of growth from GDP plus population growth on the volume side.
Tony Bancroft
And maybe to tie in a little bit of recycling, you’re the largest landfill operator, clear [deep mo] [Ph]. Can you talk about as the stream goes more to some more recycle — as the stream goes to recycling? How does that impact your landfill business? Is that a good thing, bad thing? Can you sort of give me some thoughts on that?
Ed Egl
Yes, I don’t think it’s either good or bad, right. It’s really dependent upon what the customer wants to do and that’s what we’re trying to do is help the customer, we’re also the largest recycler out there as well, and we put in our landfills about 125 million tons last year, and on the recycling side, we handle about 10 million with about half coming from our traditional nurse and half from brokerage so, so there’s still a wide gap there of kind of what’s happening, California for example, what’s the most progressive recycling state out there? Our landfills are just as full as they’ve ever been there. So, I — there’s a need for landfills out there, and by doing things with renewable energy, trying to protect the environment as much as possible, extracting value from that. I do think that there is a benefit to landfills. It’s not a negative. By recycling increasing will be benefit. I think you’ll see over a long-term, increase recycling, keeping the commodity prices high to meet the demands of our consumers on the back end is going to be a good thing overall.
Tony Bancroft
Okay. Yes. It is an end game. Yes, it is a scarcity, it is a scarcity issue. I mean, there’s that doesn’t go on forever. Maybe to margins, you’ve done a great job of growing your margins consistently, with new programs that you’ve implemented. Where could we see margins eventually going to in our waste management?
Ed Egl
Yes, we never talk about do we want to get to 30% or 35% or 40%? Whatever the margin is, right? We’re looking for continuous improvement. We expect generally somewhere between 50 and 100 basis points in a normal economic environment year from a collection and disposal business and that’s what we’re expecting. We focus a lot on return on invested capital here and proud of kind of having industry leading ROIC. Yes, I meant to mention this with on the last question, recycling on a business is the second highest ROIC out there. Landfills are one of the lowest obviously it’s capital intensity of the two businesses that drive that, but we’re focusing on both margins and ROIC.
Tony Bancroft
Yes, and maybe what are the 50 to 100 basis points? What are the levers that do that? What are the main drivers for that improvement?
Ed Egl
Yes, so it’s going to come from pricing as a piece of it, some volume growth, but also productivity improvements and operating cost reductions, right? So, all the things that we’re talking about there to improve our labor, to improve how efficiently we service our customers, standardization across the fleet and maintenance, things like that.
Tony Bancroft
Could you maybe give us a quick update on the — your — the recent now, but your large acquisition of ADS? How is that? I mean, it’s been a few — I know, it’s been a few years now. But how is that integration going? I know they had different margin profiles. Could you sort of talk to us about that?
Ed Egl
Yes, definitely. So, I think we’re fully integrated now. We had a few operations to put on our system to be clean and part of the — I think we’re through that so. So, we expect to see some synergies coming out of those pieces. We far surpass the synergies that we expected from the original deal, when we announced and that includes the vesting a whole bunch more than we expected as well. So, the transaction has been fantastic for us. As you mentioned, margin profile is a little bit different than we were surprised a little bit about the shape of some of the fleet. So, we had to invest some money in the fleet. So, that hurt us a little bit in 2021. I think we’re through most of that and we expect to see them moving closer to waste managers, traditional margins over the next year.
Tony Bancroft
Ed, just on a debt to EBITDA, you got $1 billion out of pocket for dividends. You got a couple of billion dollars for CapEx, what’s — given the new dynamics in terms of pricing versus volume, and total revenues, and margins, would you increase your leverage? You got what two to one or three to one now on whatever number you use?
Ed Egl
Yes, so I don’t think we necessarily have. So, our balance sheet is in a pretty good spot, right? We’re at 2.75 to the point, it’s right there in the middle of that two or three number that you gave, dividend is first and foremost, I think, then we look for — after in capital investment in business. And then, it’s going to go to acquisition M&A opportunity — growth opportunities. This year, we’re doing the investments in sustainability as we don’t see a lot of M&A options out there. But doesn’t mean we won’t do that. And then share buybacks. So, I don’t think there’s a need necessarily to increase leverage right now. Thereby we’re in a great spot is the way I think we — [multiple speakers]…
Tony Bancroft
Well, I reverse that. Any reason you’d want to reduce leverage?
Ed Egl
I don’t think so. I think we’re in a sweet spot. I think —
Tony Bancroft
Thank you.
Ed Egl
There’s no reason for us to pay down debt. Right now, it’s pretty cheap.
Tony Bancroft
Maybe one last quick one, just all of the — with fuel prices, energy prices going up. Can you talk about your energy business, energy environmental services business? What are you seeing right now there maybe one last recount? What are you seeing in that business right now? I know a small part of your business, but —
Ed Egl
It’s a very small part of our business right now. It really hasn’t changed significantly, right? We’re starting to see some drillers kind of get back in it and start drilling, but I don’t think it’s going to be a significant impact. Maybe if the prices — oil prices stay elevated for extended period time. We might see it, but right now it’s not that significant.
Tony Bancroft
Great, great. Well, that was an awesome overview. Thank you for taking the time today. I know you’re busy guy and —
Ed Egl
Yes.
Tony Bancroft
Look forward to hopefully having you back next year. Thanks so much.
Ed Egl
Yes. I believe we meet in-person next time. I appreciate it.
Tony Bancroft
Yes. Thanks, Ed.
Ed Egl
Thank you, everybody.
