Andy Larkin (VP of Investor Relations)

Hello and welcome to the Summit Materials 4th Quarter and Full Year 2023 Results Conference Call. Yesterday afternoon, we issued a press release detailing our financial and operating results. Today's call is accompanied by an investor presentation and supplemental workbook highlighting key financial and operating data. All of these materials can be found on our Investor Relations website. Management's commentary and responses to questions on today's call may include forward-looking statements, which by their nature are uncertain and outside of Summit Materials' control. Although these forward-looking statements are based on management's current expectations and beliefs, actual results may differ in a material way.

For discussion of some of the factors that could cause actual results to differ, please see the risk factors section of Summit Materials' latest annual report on Form 10-K and quarterly report on Form 10-Q as updated from time to time in our subsequent filings with the SEC. You can find reconciliations of the historical non-GAAP financial measures discussed in today's call in our press release. Today, Anne Noonan, Summit CEO, will begin with high-level commentary. Scott Anderson, our Chief Financial Officer, will then review our financial performance, and we'll return to close our prepared remarks with a more detailed discussion on our outlook for 2024. After that, we open the line for questions.

Out of respect for other analysts and the time we have allotted, please limit yourself to one question and then return to the queue so we can accommodate as many analysts as possible in time we have available. With that, let me turn the call over to Anne.

Anne Noonan (President, CEO, and Director)

Thanks, Andy, and welcome to everyone joining the call today. Summit stands at a very exciting and pivotal point in our company's history. Our team achieved record financial performance in 2023, accelerated our Elevate Summit strategy across all dimensions, and is embarking on integrating the Argos USA assets into the Summit family. Scott and I will take you through specifics here shortly, but we have a lot to be proud of, not the least of which is our emphasis on safety. The combined enterprise has a shared commitment to being an industry leader in safety. We are investing in people, processes, and tools, and as a result, we are putting the health and well-being of our employees and our communities at the forefront of everything we do.

I want to turn to slide four to highlight three areas of tremendous progress, starting first with how we've effectively undertaken a materials-led portfolio transformation. Since the beginning of 2023, we've entered into the high-growth Phoenix market, completed bolt-on aggregates acquisitions in targeted geographies, continued to optimize the portfolio via non-core divestitures, and completed the transformational Argos USA combination. As a result, our business is now materials dominant, with roughly 8 out of every 10 EBITDA dollars coming from either aggregates or cement. And if you recall, only 63% of our adjusted EBITDA came from material lines of business when we initially launched Elevate Summit. This intentional shift towards high-margin upstream businesses has given us significant scale in our industry.

As the fourth-largest cement and the sixth-largest aggregates producer in the U.S., we can leverage our collective spend to achieve scale synergies, tap into deeper talent pools, and amongst other things, deploy best-practice knowledge sharing across the whole of our enterprise. Second, thanks to excellent and widespread commercial execution, solid contributions from every reporting segment, and a growing focus on operational excellence, we were able to grow Summit's adjusted EBITDA margins by 160 basis points in 2023. Our team has adeptly navigated inflationary pressures and dynamic demand conditions to improve the quality of our earnings and put us on solid footing to deliver continued margin expansion in the year ahead. And lastly, with an organizational focus on portfolio optimization and a well-equipped balance sheet, we can continue our aggressive pursuit of aggregates-oriented M&A.

We have a robust and promising deal pipeline as we endeavor to build an even more materials-led, higher-growth business. This isn't just talk. A week ago, we completed a strategically attractive bolt-on acquisition in our new Phoenix platform, a proprietary aggregate-centric deal that builds our reserve base, extends our presence along a major growth corridor, and we expect will become immediately accretive to our margin profile. It's a deal that checks all the boxes and provides a template for our future M&A ambitions. Furthermore, in Q4, we completed two divestitures of subscale, mostly downstream assets in non-strategic markets. These transactions, executed at attractive multiples, generated $75 million in proceeds, fortifying an already strong balance sheet and providing additional dry powder for future AGS opportunities. Our overall progress is more evident when considering our Elevate Summit scorecard on slide five.

For Summit standalone, at 2.1x net debt to EBITDA, we have effectively employed a disciplined and growth-oriented approach to capital allocation. Critically, on a pro forma basis, our net leverage remains well below the 3x target, which gives our balance sheet ample flexibility for further portfolio-enhancing acquisitions and to fully fund organic growth opportunities. For ROIC, at 10.4%, we established a new high watermark, adding 10 basis points sequentially and 130 basis points in 2023 by taking a total portfolio approach, one that scrutinizes every asset against our return and margin criteria. And if there isn't a clear and achievable path to reaching Elevate financial hurdles, then we've demonstrated a proficiency at finding better owners for these assets. Adjusted EBITDA margin for 2023 was 23.7%, an all-time Summit record, and 160 basis points higher than the year-ago period.

Scott will walk you through the mechanics, but in short, we have strong profitability performance across the portfolio despite challenging cost dynamics and a slowdown in residential demand. All the credit goes to the teams across our footprint who stayed focused, executed with incredible agility, and delivered admirably on each one of our 2023 financial and strategic commitments. Before I hand it to Scott, I do want to extend our gratitude to our shareholders, who voted earlier this year to overwhelmingly approve the Argos transaction. While we believe the merits of the deal stand on their own, having a resounding endorsement from our shareholders is a vote of confidence as we begin our integration. We do not take your support for granted, and we continuously aim to earn your trust each and every day.

With that, I'll turn it over to Scott to walk you through the financials, and then I'll come back to discuss our 2024 outlook. Scott.

Scott Anderson (EVP and CFO)

Thanks, Anne. I'll pick up on slide seven, where you see a record-breaking financial performance for both the fourth quarter and the full year. In Q4, net revenue increased 19.8%, driven by a combination of ongoing pricing momentum across each line of business, acquisition benefits, and accommodating weather in parts of our footprint. Fourth quarter, Adjusted Cash Gross Profit and Adjusted EBITDA increased 15.9% and 14.5%, respectively, primarily reflecting the compounding impact of year-to-date pricing, volume growth in most lines of business, and less severe cost inflation. For the full year, Summit set all-time records up and down the P&L, as inflation-justified pricing, together with commercial excellence execution, were the primary thrust for net revenue growth of 9.9% and Adjusted EBITDA growth of 17.6%. Additionally, we've witnessed our operational excellence program start to bear fruit, although we believe there's significant runway on this organizational imperative.

Unpacking fourth quarter line of business volumes on slide eight, which show improving year-on-year trends relative to Q3 in each line of business. While we do see demand conditions beginning to improve, mild and dry weather in key markets extended our construction season and was partially responsible for the sequential improvement in volumes. Specifically, Utah and Texas, areas of particular portfolio strength, had exceptionally dry weather that allowed for more activity into December. Also of note, Q4 was a particularly difficult comparison for our cement business. If you recall, in Q4 of 2022, we imported roughly 23% of our volumes. This year, we reduced our Q4 imports by more than 40%, which has a negative impact on volumes, but as you'll see, it has favorable mixed benefits for cement's margin profile.

On the full year, organic volumes by line of business tracked with our end-market expectations, namely the residential end market and sluggish demand in Light Non-Res impacted our ready-mix most acutely, followed by cement and aggregates. Asphalt, on the other hand, increased 10.1% organically, as our primary asphalt markets in North Texas and the Intermountain West experienced double-digit volume growth on a full-year basis and benefited from robust ongoing public infrastructure investments. Turning to pricing trends on slide nine, there are two things I'd like to highlight. One, and what should be obvious, we are operating in a constructive and enduring commercial environment. Local demand, cost factors, and go-to-market execution have combined to drive exceptional pricing performance across our lines of business and across our markets. Second, despite a more challenging prior-year comparison, our price realization remained resilient.

Aggregates pricing increased nearly 15% in 2023, with above-average growth in Houston as well as the Missouri markets, followed closely by gains in North Texas and the Intermountain West. Cement achieved 13.2% growth in 2023, reflecting favorable supply-demand conditions and better price realization in our northern and in the cement markets. The slight sequential moderation in cement average sales price between Q3 and Q4 does reflect customer mix impacts. Absent that impact, pricing would have been sequentially up by over $1 in Q4. Downstream, pass-through pricing supported ready mix pricing growth in 2023, with both Salt Lake City and Houston, our two primary ready mix markets, achieving solid pricing gains throughout the year. Crucially, ready mix pricing was up 11.2% in 2023 despite volume headwinds demonstrating our market leadership in attractive and advantaged ready mix markets.

Asphalt pricing increased 7.9% in the quarter and 15.6% in 2023, reflecting higher input costs, improved job selection, and strong demand pull-through. Slide 10 is a snapshot of adjusted cash gross profit margins. Here, we were able to achieve margin expansion throughout the portfolio and effectively contend with elevated and persistent cost inflation. On a full-year basis and collectively, our variable cost basket increased approximately 9.5%, with stiff cost headwinds from several cost categories, including cement for our ready mix operation, kiln fuels, other energy components, and supply chain-related cost buckets. That said, we did see the pace of cost inflation moderate in the fourth quarter, signaling a continued, even if prolonged, normalization of our cost curve.

Specific to aggregates, we added roughly 90 basis points year-on-year in Q4 and 140 basis points in 2023, but it is important to flag that we are still in the margin recovery phase as profitability levels for AGS are below 2021 levels. That is to say, through productivity gains, ongoing commercial excellence implementation, and a greater contribution from higher-margin greenfields, we have the opportunity to add percentage points, not basis points, to our aggregates margin profile in 2024. On cement, in the fourth quarter, rain in November provided some relief along the Mississippi River, and that, combined with reduced imports and pricing, helped to boost margin 100 basis points year-on-year. Stepping back, our legacy Summit cement business continues to operate at a very high level with strong operational and commercial execution, leading to a 380 basis point improvement in cash gross profit margins in 2023.

Our performance provides confidence and momentum as we look to apply our expertise in this proven Elevate playbook to generate cement synergies in the coming years. Downstream, Q4 ready mix margins effectively sustained prior-year levels while asphalt margins moderated year over year as energy-related costs, including liquid asphalt, escalated. Despite this, and on a full-year basis, product margins grew 110 basis points. Closing out on slide 11 with an initial comment on adjusted diluted earnings per share, which increased $0.31 or 24% in 2023 as gross margin expansion more than offset increased G&A expenses and interest expense for the year. In terms of free cash flow, it took a sizable step up in Q4 and, by extension, in 2023, as operating cash flow powered the step up. Enhancing our free cash flow generation is a core component of the Argos transaction.

This, alongside a manageable leverage profile, prompted the recent upgrade to BB Plus from S&P Global, a move we felt was warranted but nonetheless appreciated. Finally, after further efforts to retire our Up-C structure and in combination with shares issued in relation to the Argos transaction, for the time being, please use a share count of 175 million moving forward. This includes 174.3 million Class A shares and 763,000 LP units. With that, I'll turn it back to Anne for a discussion of our combined enterprise and a look ahead to 2024.

Anne Noonan (President, CEO, and Director)

Thanks, Scott. Let's start by clearly and quickly resetting what our new business looks like. On January 12th, we completed the Argos USA transaction and have since been diligently working towards bringing our teams together. From IT and operations to procurement and sales, we've hit the ground running and accomplished a lot in just over a month. And while we'd be in position to share more details on our integration at next month's Investor Day, we want to provide what the 2023 pro forma portfolio looks like on slide 13. As you can see, we remain well diversified with a relatively even split between public, residential, and non-residential. Our geographic mix is enhanced and tilted towards higher-growth states that are benefiting from substantial public and private investments, as well as positive migration trends.

By significantly increasing our presence in year-round Southeast markets, we reduce our seasonality and, by extension, reduce the quarter-to-quarter fluctuation in earnings. As you would expect, our profit mix is geared towards materials, with cement making up approximately 43% of our cash gross profit, followed by aggregates at 27% and downstream at approximately 25%. As you move down to Adjusted EBITDA, that materials mix approaches 80% of the overall business. Bottom line is that with this new portfolio, we've accelerated our Materials-Led Strategy, are operating in growing and advantaged markets, and have end-market diversification that helps provide through-cycle economic durability and resiliency. The Argos assets closed the year with very strong performance. Aided by favorable weather, they outperformed our original expectations and achieved Adjusted EBITDA of $343 million and an overall EBITDA margin of 20.1%.

Relative to a purchase price of $3.2 billion, the headline multiple is very attractive at just over 9x. We clearly have a strong platform for growth and even greater confidence that our post-synergy multiple will be nearly 7x after we complete our integration plan. Of the $343 million, approximately 85% was generated from cement and the remaining 15% coming from ready mix. Together, our pro forma 2023 EBITDA was $921 million, and the combined adjusted EBITDA margin in 2023 was 22.2%. Given the shift in seasonality, the quarterly cadence for the new enterprise will be more balanced. Using round numbers, roughly 10% of EBITDA should be generated in Q1, 30%-35% in Q2 and Q3, and roughly 25% in Q4. I will say these are very likely to be imprecise, but nevertheless, our aim is to inform how to think about the composition of the upcoming year.

Now, having reset in broad strokes our 2023 baseline, let's look ahead. Our official 2024 EBITDA guide is $950 million at the low end to $1.01 billion at the high end. Inclusive in this range are five core drivers. First, we expect to generate at least $30 million in operational synergies. We will go into more detail at Investor Day on where our synergies are coming from and the overall glide path, but for now, our current perspective nearly mirrors what was uncovered during diligence. We anticipate the synergies from ready mix and procurement to come relatively quickly, as well as cement synergies in the form of PLC optimization. Furthermore, these 2024 expectations align closely with our commitment to deliver at least 50% or $50 million of our total synergy target within the first 24 months.

The second core driver is the persistence of pricing momentum across the portfolio. As you know, on January 1st, we implemented price increases across the Summit footprint and in every line of business. Overall, we are seeing very good traction in our markets. Our value pricing approach contemplates market-specific factors and demand conditions at the local level. As such, our aggregates price increases are designed to be margin accretive and did range from mid-single digit to double digit in some areas to start the year. Importantly, today's guide only incorporates what we have actioned to date, and we certainly think there is a high probability that additional pricing actions are on the horizon, although it's too early for us to provide those specifics. On cement, our starting points vary between our river markets and the legacy Argos footprint.

If you recall, January 1st pricing along the river was $15 per ton, and that execution is proceeding reasonably well, with northern markets experiencing better traction than our southern markets, as you would expect. In the Southeast and Mid-Atlantic, we are likely to encounter some near-term noise as we fully wrap our arms around existing customer contracts and better understand the upside opportunity from applying our value pricing and customer segmentation discipline. What this means is, to varying degrees, we anticipate pricing growth in these markets to trail the rest of the portfolio, at least to start the year. That said, we have demonstrated sharp commercial execution along our river markets with consecutive years of double-digit pricing gains. We will move swiftly to apply the same standard of value pricing to the new cement markets within our portfolio.

We will take the first opportunity to work with our Southeast and Mid-Atlantic customers to appropriately execute pricing adjustments to fully reflect the unique value we bring to the marketplace. The third component for our outlook is on cost trends. We anticipate cost inflation to moderate across most of our cost categories in the year ahead. And while we're confident the pace of inflation will slow, the downward pitch of that cost curve is difficult to project, so we'll provide more color as we move through the year. Fourth, we anticipate our operational excellence initiatives to really take hold in 2024. We spent 2023 getting our feet under us, building talent and capabilities so that we can drop serious savings to the bottom line this year. These productivity gains, together with a positive price-cost relationship, are expected to drive strong aggregates margin expansion in 2024.

And finally, we believe on the whole, underlying demand will improve as we move through the year. In this dynamic environment, however, demand trends can and will vary by end market and by geographic market. With that in mind, we have characterized our view on the three end markets, beginning on slide 15, with our residential outlook. Our long-run view hasn't changed, and like others, we believe there is a compelling case to support persistent and substantial investment in U.S. housing. Since the 1980s, the U.S. has consistently reduced the supply of housing relative to household formation. From 1960 to 1980, on average and as a nation, we produced more than 20 housing starts per 1,000 households. That figure stepped down to 15 starts between 1980 and 2000, and over the last 23 years, we have produced roughly 11 housing starts per 1,000 U.S. households. Our supply is clearly constrained.

Our existing inventory is certainly aging, and demand does not appear to be letting up. Taken together, these factors point to a severe shortfall of U.S. housing supply. Experts can debate if that shortage is 3 million or 7 million units, but at the end of the day, in order to address that gap, we need a renewed commitment to rebuild our housing system in the U.S. If the long-term residential trajectory is up and to the right, the short-term picture is more clouded. On one hand, months of supply is well below a healthy equilibrium of 5-6 months. Consumer and homebuilder sentiment has sequentially improved, permitting declines are moderating, and construction costs are coming down. On the other hand, affordability remains historically poor and remains a significant overhang nationwide and in most of our major residential MSAs.

On balance, indicators are signaling reduced uncertainty, and we appear to be on a path to recovery and then growth, but that path may look different from market to market. For example, Houston's unique economic factors, favorable zoning rules, and a higher proportion of large-scale builders create the conditions for a more swift recovery. Salt Lake and Phoenix, by contrast, are facing stiffer affordability headwinds, so while we're cautiously optimistic, we are factoring in a slower recovery. In summary, until we see mortgage rate relief, we are maintaining a modest outlook regarding residential in 2024. Judging by recent history and the fact that nearly 90% of homeowners are locked in at interest rates under 6%, we think if rates trend towards 5%, that should unlock demand and spur greater activity overall. But until we get there, our planning stance is for flat-ish residential performance this year.

For non-residential, on slide 16, the headline message is that trends we experienced in 2023 should carry into 2024. That means heavy growth moderated by and maybe more than offset by sluggish, light non-res activity. This is where our specific footprint and project pipeline really matters. And for us, we are playing in markets that are benefiting from CHIPS and IRA investment. In fact, nearly 60% of the announced investment is occurring in top Summit states. Timely investments in Arizona to build out that new platform should really pay dividends in the years ahead, as semiconductor investment is concentrated in the Sunbelt. And we are also seeing data centers come into focus in Phoenix. In Kansas, our green energy project pipeline remains robust, with five energy projects currently in the pipeline. Similarly, in the Carolinas and Georgia, ongoing investments in alternative energy infrastructure are benefiting our footprint in the Southeast.

Elsewhere, a lot has been made of overbuilt warehousing in the country, but for us, it's not a major component of any of our platforms. It may, however, have an indirect impact whereby it may increase competition for other end uses. Lastly, the outlook for light non-res is spurred to remain dormant in 2024. Between tighter credit standards and recent residential trends, it would be premature to expect activity to recover in verticals like retail, office, and lodging. So as to not undersell its impact, light non-res has historically made up roughly half of our commercial business, so this represents a not-insignificant headwind, particularly in our ready-mix and cement markets. So overall, the demand outlook is mixed for non-res, with flat organic volumes likely representing the high end of our current expectations.

Then for the public end market, we'll consistently come back to our three leading indicators to provide a comprehensive view on infrastructure activity. Slide 17 profiles our top eight state DOT budgets, which show varying degrees of strength but are up collectively 16%, which is above the national average. Importantly, our public exposure is not even among our states and is disproportionately weighted toward areas with heavier asphalt operations. This notably includes Texas, which comprised more than 40% of our asphalt volume in 2023 and is witnessing a strong step up in DOT funding in 2024. The second indicator is highway and paving awards for our top states. As of December, on a trailing 12-month basis, highway and paving awards have increased 14% versus the comparable year-ago period, more than twice the rate of growth for all other states.

Then we look at backlogs, as these are the truest indicator of upcoming activity, and our backlog activity is either maintaining very healthy levels like in asphalt or is up substantially like in aggregates and ready mix. So with indicators all flashing green, we think it's fair to expect mid-single digit or better growth in public volumes for 2024. Summing it up, I think we start this year with a guarded optimism around demand conditions, with much depending on Fed moves and the path of interest rates. Rather than prognosticating on future rates, we are comfortable taking a measured stance and setting organic volume expectation around flat for 2024, which fully incorporates a slow year-to-date weather-impacted start to our year.

At the end of the day, we feel very positive about the year ahead, controlling what we can, achieving a comfortable gap between price and cost, and delivering strong EBITDA growth for 2024. Turning now to capital allocation on slide 18, you'll see in our guide we've called for between $430 million-$470 million in CapEx. This aligns with our commitment to keep CapEx as a percentage of net revenue at approximately 10% in the near term before stepping the proportion down over time. Much of the CapEx investment is designed to assist in the winter turnarounds at our cement plants and to carry forward our ready mix fleet modernization initiative. These specific investments are targeted to either improve profitability or avoid unplanned downtime. In both cases, it is high-return spend that is necessary to more profitably run the legacy Argos assets.

You'll see that at 10% of net revenue, we are actually reducing capital intensity. Together with improved enterprise profitability, this should help drive a 15% or more increase to free cash flow per share in 2024. This is central to our overall value creation thesis, as greater cash flow conversion and generation will increase our optionality to reinvest in growth CapEx and aggressively pursue accretive AGS-oriented M&A, all while effectively managing our leverage. Summit is a growth company with a compelling set of opportunities in front of us, and our capital allocation priorities underscore that growth objective. I'll close by reiterating our near-term priorities on slide 19. In the midst of a large-scale integration, it can be easy to lose sight of what the goals are.

But we, as an organization, are committed to safely integrating our two companies, accelerating aggregates growth, delivering on our synergy commitments, and using our enhanced free cash flow profile to further optimize the portfolio and strengthen an already fortified balance sheet. These priorities guide our actions and decisions and only fuel the four Elevate Summit priorities of market leadership, asset light, sustainability, and innovation. As we collectively execute and create a stronger Summit, we are confident we can deliver industry-leading value for our employees, our stakeholders, and Summit shareholders. With that, I'll ask the operator to open the line for questions.

Operator (participant)

Thank you. At this time, I would like to remind everyone, in order to ask a question, press star, then the number one on your telephone keypad, and we'll pause for just a moment to compile the Q&A roster. Thank you. Your first question comes from the line of Stanley Elliott from Stifel. Your line is open.

Stanley Elliott (Director)

Good morning, everyone. Thank you for the question, and congratulations on the deal. Very exciting.

Anne Noonan (President, CEO, and Director)

Thanks, Stanley.

Stanley Elliott (Director)

Scott, you mentioned adding points to the margin profile, potentially on the aggregate side. Could you help us with kind of the puts and takes as to how we might get to the high end of it versus kind of what you mentioned, possibly on the more of a basis point sort of a buildup?

Anne Noonan (President, CEO, and Director)

Yes. So from a point of view of where we started here, as you saw, we've had progress in the last two quarters on aggregates margin expansion, and that has been driven largely by pricing and some op excellence wins as we've gone through. We ended the year on a trailing 12-month cash-adjusted gross profit margin of about 49%, bumping that 50%. We've set a target there of 60%. And we've been playing a bit of catch-up in AGS with cost inflation, etc., but the two key drivers are pricing has been very strong as we've seen right throughout 2023, and we'll continue that value pricing mentality as we go into 2024.

We think it's a very constructive environment for aggregates moving forward, and that's driven by, as you know, Stanley, a core tenet of our Elevate strategy is to be market leadership, number one or number two in all of our local markets. Supply-demand dynamics are very strong. There's persistent cost inflation, and our January price increases are out there very strong, and what you have in the guide right now is only one price increase. It doesn't have the mid-years. But the other part that I point you to, which is a difference and an acceleration from 2024 or 2023, which will push us to the high end, is the OpEx. So as you know, we made progress last year. We actually dropped $15 million to the bottom line from our continuous improvement events in ags.

This year, we expect to double our amount of Continuous Improvement Events. We've brought on Marshall Moore as our Chief Operations Officer, and we'll add more resources. That's what will push us to the higher end of that ags profile. We expect to increase our ags expansion in 2024.

Stanley Elliott (Director)

Great. Thanks so much.

Operator (participant)

Your next question comes from the line of Garik Shmois from Loop Capital Research. Your line is open.

Garik Shmois (Managing Director)

Oh, great. Thank you. If you could speak to the operational synergies that you called out, $30 million, how much of that has been secured here shortly after closing the Argos deal? And maybe if you could provide some color on how you expect that pacing to occur throughout the balance of the year.

Anne Noonan (President, CEO, and Director)

Okay. So let me start just at a high level. So the $30 million, we're very confident in our ability to deliver that. If you recall in our proxy, we had actually $20 million for the first year in the proxy. So we've gotten nothing but validation of our operational synergies. We've had our teams together working very closely on workshops. And so if you think about the actual amount of synergies, what will come in first from a pacing perspective is really the scale synergies, which will be from SG&A and procurement. The next synergies you can expect to roll in are ready mix. We're very encouraged by a lot of the opportunity we have in ready mix. We have the ongoing fleet modernization program that Argos had started and will complete, and that'll improve margin expansion on ready mix.

Then the teams are actively putting together enhancements to delivery, improving the footprint, bringing in technology like Load and Go. That's all moving very quickly in ready mix, and we can move quickly in ready mix. Cement, our key focus for 2024, and we're very confident in this, is the ability to improve the operational equipment efficiency, and that'll reduce costs, increase our productivity, and most importantly, allow us to have more domestically produced cement from the legacy Argos assets versus relying on imports, which will expand our margins. So all in, we're very confident around that $30 million. Scott, maybe you want to talk to pacing on how that might occur throughout the year?

Scott Anderson (EVP and CFO)

Yeah. So Garrick, when you think of pacing or phasing throughout the year, we don't necessarily provide quarterly guidance on that, but what I would say, it's going to really mirror the operational activities of the year. And obviously, we need a little time to ramp up here in the beginning, but as Anne mentioned, the teams are very engaged right now, and we're seeing progress. But I see it kind of aligning with the EBITDA performance of the business throughout the year.

Anne Noonan (President, CEO, and Director)

The other thing I would add, just you asked specifically, Garrick, to operational synergies, but one of the things that I've been extremely encouraged by is immediately after close, we had workshops with all of our commercial folks, and they have really been digging into the details and coming up with value pricing opportunities, procurement opportunities. But additionally, some ags pull-through opportunities will represent additional upside. We'll update you more on that in our investor day, but I would say all in all, that $30 million is pretty secure, and we're very confident in having some upside as we move through the integration period.

Operator (participant)

Sir, does that complete your question?

Garik Shmois (Managing Director)

Yes, it does. Thank you.

Operator (participant)

Thank you. Your next question comes from Phil Ng from Jefferies. Your line is open.

Phil Ng (Managing Director)

Hey, guys. Congrats on the solid core. Free cash flow is certainly very impressive. I guess my first question was really around the magnitude and timing of the cement price increase you anticipate to see kind of in the Southeast Atlantic, Mid-Atlantic region in terms of the magnitude of what's been announced. How long do you kind of think it'll take to kind of work through some of these contracts and bring to your value pricing? And any more color around imports? I know Red Sea and Panama Canal. Has that been a tailwind in terms of tightening up the market as well?

Anne Noonan (President, CEO, and Director)

Yeah. Let me kind of step back on cement pricing. So as we said in our prepared comments, Phil, if I just take legacy Summit business, we went out at $15 a ton, relatively strong price execution as the team has done the last two years, demonstrated double-digit price increase. And we won't hold out for if demand and customers allow. We will have a mid-year price increase as we've done the last two years. So we're really solid and secure in our value pricing principles and in our customer segmentation on legacy Summit. As I said in my prepared comments, a little bit of a different game when it comes to legacy Argos.

There we have longer-term contracts, which some of those will be rolling off as we go through 2024, and the teams are working through that, and we're working with our customers to expect value pricing principles to come in on that. We also have larger customers than you would have. And if you remember, if you go back to how Summit started this journey on customer segmentation, basically becoming less reliant on power buyers, you can expect that same kind of discipline as we look through and work with our customers customer by customer to optimize our customer mix. So that's going to take a little bit of time. There is some immediate impact that January price increases on the legacy Argos side where it is as robust as on the Summit side.

Now, remember, Summit had a lot of heavy high-budget costs, so that really supported a very high price increase as we went in. We've had strong secure of that. But we do believe there is upside on pricing in the legacy Argos just base business. There's some catch-up pricing to be done. So think about it in terms of large contracts rolling off, customer segmentation and catch-up pricing on the January. At the end of the day, do I think we'd be double-digit every year like we were in 2022 and 2023? But high single digits is probably a good estimate for our cement business.

Phil Ng (Managing Director)

Any color on the import dynamic?

Anne Noonan (President, CEO, and Director)

Yeah. So imports, one of the nice things that exists, as you know, the existing Summit business, legacy Summit business, really only has 5%-10% in Louisiana, which is where imports come in. The Argos business, similarly, if you look at the Mid-Atlantic and Southeast, if you look at total imports into the U.S., only 5%-10% actually come into those markets. So we're not heavy import exposed overall. So I would say we're much more focused on margin expansion on the Argos business, on profitability expansion, and that's around the pricing we just discussed, but also landing the operational synergies in our cement. And we are very confident of strong EBITDA growth in our cement business in 2024 for those two reasons.

Phil Ng (Managing Director)

Okay. Super. Thank you, Anne. We really appreciate it.

Anne Noonan (President, CEO, and Director)

Thanks, Phil.

Your next question comes from the line of Adam Thalhimer from Thompson Davis. Your line is open.

Adam Thalhimer (Director of Research)

Hey, good morning, guys. Hey, Anne, at a high level, can you talk about the relationship with Argos and how you expect that to trend over the next few years? And then is Argos under a standstill provision, or could they actually buy Summit shares in the open market?

Anne Noonan (President, CEO, and Director)

Yeah. So on the latter part, Argos has a two-year standstill. And the relationship is we have three new board members own 31%. They're 31% shareholders of our company. But most importantly, the relationship is very strong. We're very united on the strategy of the company. This deal wouldn't have come together, frankly, without that. This is something which, as we've integrated the two teams, I've been extremely encouraged to see. I've been personally out to every one of the cement plants at this point. I still have to get out to all the ready mix. It's a little more of a challenge. But our teams are all out there. The teams are integrating extremely well. And on a people side, I would say the enthusiasm, engagement, and creativity that's coming out of those teams, it's very encouraging.

On the business side, validation of the synergies has been. We've gotten no surprises, only upside from the commercial side. I expect this to be a very long-term and sustainable relationship. Argos got in here because they want to participate in the U.S. and the growth. This is a long-term partnership that you can expect, Adam.

Adam Thalhimer (Director of Research)

Great. Thank you, Anne.

Your next question comes from the line of Anthony Pettinari from Citigroup. Your line is open.

Anthony Pettinari (Managing Director and Senior Equity Analyst)

Good morning.

Anne Noonan (President, CEO, and Director)

Morning.

Anthony Pettinari (Managing Director and Senior Equity Analyst)

If I look at the 2023 performance versus what you had forecast in the proxy, it seems like Argos did much better in 2023 than you expected. I was wondering why that was. Then maybe a related question, the 2024 guide at the midpoint maybe looks just a touch below what was discussed or maybe implied in the proxy. I'm wondering if there was anything driving that.

Anne Noonan (President, CEO, and Director)

Okay. I'll talk the latter part of that, the 2024 guide, and then I'll have Scott actually maybe address the 2023. Would that be okay?

Anthony Pettinari (Managing Director and Senior Equity Analyst)

Sure.

Anne Noonan (President, CEO, and Director)

All right. So the 2024 guide, we had in the proxy, $1.018 billion, and I would say basically, and you got to remember, that's a point in time, and that was mid-2023 we put that in place. I would say the things that have brought the guide down slightly, I still think it's in the ballpark overall, is we've done two divestitures on the Summit side, which were about $8 billion in EBITDA. We've also been able to assess now since January 12th in and really fine-tune dis-synergies. And so that number's been refined. And then the third factor I'd encourage you to look at, Anthony, is more around we've done now a bottoms-up volume and price total analysis of the legacy Argos business. And so that's what got us to the overall number.

I would say our guide overall is we're very confident in that guide that we've put out there in the midpoint. If anything, we would skew to upside on that guide. Scott, you want to talk about 2023?

Scott Anderson (EVP and CFO)

Yeah. For Argos 2023, Anthony, you're right. Back in September, we thought the low 300s was kind of the expectation. And similar to us, Argos finished really strong to come in at that 343 number. And I don't want to speculate because we didn't own it till January, but I know their pricing was starting to really take traction. And just some of that fleet modernization and their OPEX journey, they got started on that we're going to carry through. But really excited to see the momentum they have as well as our momentum coming in 2024.

Anne Noonan (President, CEO, and Director)

Yeah. I mean, the other thing I'd point you to, Anthony, is the total margin of the combined entity was 22.2% on a pro forma basis. We're very confident in bringing that number in 2024 to a range of 23%-24% EBITDA. And that'll be driven by price costs across the entire portfolio, ags OPEX excellence, and delivering that $30 million across synergies that we've talked about. So we see a pretty clear path. Then portfolio optimization will only provide upside. So this starting point that we're talking about for 2023 gives us a nice jumping-off point to really leverage down on the three key elements that we talked about growing the business on.

Anthony Pettinari (Managing Director and Senior Equity Analyst)

Okay. That's very helpful. I'll turn it over.

Your next question comes from the line of Brent Thielman from D. A. Davidson. Your line is open.

Brent Thielman (Managing Director and Senior Equity Analyst)

Hey, thanks. Good morning. I think one for Scott wasn't quite clear to me, but the step-up in CapEx this year, could you just talk about the cadence of that? You mentioned targeting some winter turnarounds. Wasn't clear to me if we're front-end loaded on the CapEx or the more spread out.

Scott Anderson (EVP and CFO)

You bet, Brent. So when we think of CapEx, we've talked about the 10% threshold kind of being our goal here of maintaining that at net revenue. But when you think about the phasing of it, we don't really provide phasing. But I can tell you, just like you called out, it will be weighted towards the front. I would say kind of a 60/40 if you looked at the first half of the year to the back half of the year. And that 60% in the front, really, there's two reasons to drive that, Brent, really. First is that's when the plant shut down. The plant shutdowns are occurring. So we're really putting that capital into those plants to raise that OEE and that operating performance early in the year. And then just the second part is really just the deployment.

We want to get that money to work for us as early as we can in the year so we can get the returns on those growth and profitability CapEx projects. So really, that's what you're looking at. We will want to push early in the year as we can and get the use of that capital.

Brent Thielman (Managing Director and Senior Equity Analyst)

Okay. Very good. Thank you.

Operator (participant)

Your next question comes from the line of Keith Hughes from Truist. Your line is open.

Keith Hughes (Managing Director)

Thank you. When you were going over your end-market view, I think you came up with kind of a flat unit scenario for 2024. Did I hear that right? And is there differences amongst the different products of what you think unit change will look like in 2024?

Anne Noonan (President, CEO, and Director)

Yeah. So let me kind of give you the high level across end markets just at a high level, and then I'll go into line of business to address your question, Keith. So you're correct. We kind of came across as flat-ish overall. So that really is made up of residential being flat-ish, non-residential heavy being stronger, light being dormant and weak. So we kind of say flat to down on the non-residential, and then public mid-single digit or higher. So how that plays out in our actual lines of business, I would think of it in terms of aggregates and ready mix being flat. We talk about cement flat to down, and that's because it's heavy non-residential. And then we talk about asphalt volume's going to be high mid-single digit overall. So we're going to have less imports as well on cement, so we'll have more domestically produced.

So lesser imports, more reliant on higher margin cement business is how I would look at it. Now, that being said, I will say we are taking what I would call a guarded approach to volumes because really, on one side, I would say there's pent-up demand on residential, and that could pop if interest rates get, as I said in my prepared comments, to 5%. So there is definitely an opportunity for that to swing up to the right side. That's kind of tempered against a January that had a lot of weather. Now, our team's really good at picking up from weather, but we did start in a bit of a hole here. And we also have pretty much a dormant non-residential, which is a significant part of our portfolio.

But I would think about volumes overall, we started from a stance of guarded and cautious because that allows our team to react in a very appropriate way. That's by focusing on price, focusing on ags margin expansion OPEX excellence, focusing on our synergies, and portfolio optimization, controlling what we can control. And then as volume would kick in at the end, you should see that as upside and the potential to have a compounding effect of strong pricing actions.

Keith Hughes (Managing Director)

Okay. Thank you.

Anne Noonan (President, CEO, and Director)

Thanks, Keith.

Your next question comes from the line of David MacGregor from Longbow Research. Your line is open.

Joe Nolan (Associate Analyst)

Hey, good morning. This is Joe Nolan for David. I was just wondering, first quarter's seen a little bit of weather, and you talked about the 10% EBITDA in the first quarter. I was wondering whether that was more of a long-term view or whether that was 2024 specific, and we might see that skewed a bit lower just due to the weather this year.

Scott Anderson (EVP and CFO)

Yeah, Joe, I'll take that one. You're right. January was rough, and I think everybody felt the weather impacts for January. We think we're still going to hold to that 10%. We feel like that February things, we still got enough time to build that back. So it wouldn't necessarily change our outlook. And you looked to the history. Summit legacy was kind of a 5%-7% in that Q1. And now with the addition of Argos, it's more complementary in the seasonality. So now we're pushing that up to 10%, but I think we still hold to that 10% and plan on getting it back at this point, Joe.

Joe Nolan (Associate Analyst)

Got it. Thank you. That's helpful. I'll pass it on.

Your next question comes from the line of Noah Merkousko from Stephens. Your line is open.

Noah Merkousko (Senior Associate)

Good morning. Thanks for taking my questions, and congrats on the strong results.

Anne Noonan (President, CEO, and Director)

Thanks, Noah.

Noah Merkousko (Senior Associate)

So yeah, just one quick one here. The asphalt volumes were really strong in the quarter up 27.5%, I guess. Is that a one-time big project, or is something like that, some really strong growth rate, something we can see continue as we look through 2024? I'd imagine infrastructure plays a big role in driving volumes there.

Scott Anderson (EVP and CFO)

Yeah. I mean, Q4, you're absolutely right, Noah. It was high, but it was really weather. We had very favorable weather. So our guys, every crew we had, were out in the road. That's all I can tell you. And we had a ton of backlogs, which we still do in asphalt. So on a full-year basis on an organic growth, you'll see that our asphalt was up like 10%, but very heavy in Q4 just because we got particularly favorable weather.

Noah Merkousko (Senior Associate)

Once in a while, we got to call out the good weather, even though January returned.

Got it. I think that, correct me if I'm wrong, but the answer to Keith's question, kind of thinking about asphalt volumes up in the mid to high single digit range.

Scott Anderson (EVP and CFO)

Yeah. You can look at it that way. Now, we have a very tough comp on the first half, I would say, of asphalt because it had a very significant increase where we saw a big slug of pipeline in 2023 come in from we always said we would be the beneficiary of repair and rebuild being the first of the infrastructure dollars to come in. And we started to see that in 2023. And so what you can expect, Noah, is as we go into 2024, really healthy asphalt backlogs, but we also have really healthy aggregates backlogs that are all tied to that public funding.

Noah Merkousko (Senior Associate)

Got it. That all makes sense. Thanks for the time, and good luck with the rest of the year.

Scott Anderson (EVP and CFO)

Thanks, Noah.

Your next question comes from the line of Kathryn Thompson from Thompson Research Group. Your line is open.

Kathryn Thompson (Founding Partner and CEO)

Hi. Thank you for taking my questions today. Now that the heavy lifting is behind you with getting Argos over the finish line, but that's over the finish line, and you're focused on integration with Argos within Summit. But touching on commentary about just that continuous pruning of non-core assets, two parts on that. One, what are your priorities? And then two, kind of alongside with that, how has that changed with Argos, and is the pace and the type or geographic mix some of the relatively greater drivers for pruning your portfolio? Thank you.

Scott Anderson (EVP and CFO)

Thanks for the question, Kathryn. So yes, we are, as you know, we've always talked about portfolio optimization as a process, not a project, for Summit, and we will continue to be that way. Every priority we have is driven around reaching our Elevate Summit financial metrics that we've set. So we've said we want ROIC above 10%, and we're pushing the portfolio to over 30% EBITDA margin. So every asset is scrutinized at Summit, and that includes legacy Argos assets. If we don't see a clear path to those kind of metrics, we will find a better owner. We've demonstrated that yet again here in the fourth quarter. I will say it doesn't change our overall strategy. Our overall strategy was to become more materials-led. Obviously, the Argos acquisition allowed us to increase that to over 80%.

So we've really got that materials part moving for us at a good time in growth for all of our end markets. Our geographies have been further fortified by this combination, and that's getting less seasonality into our business and having that exposure to high-growth MSAs in the Southeast. Our pruning also is around we have said we're going to grow new platforms. Think about the acquisition we did this quarter was very important. It was adding 30-year reserve in Arizona and a high-growth corridor where we said we were going to build out that ags platform. Some of the pruning were in geographies, frankly, where we're not focused and they're non-strategic and non-core.

We still keep this ongoing list of tier one, two, and three that are on our divestiture list that have to meet the financial targets, and they also align very strategically with our Materials-Led Strategy.

Kathryn Thompson (Founding Partner and CEO)

Just to follow up on that, if you're able to share, what are those top three criteria that you just referenced in terms of?

Scott Anderson (EVP and CFO)

The top three criteria? Materials-led?

Kathryn Thompson (Founding Partner and CEO)

Okay. Yeah. Okay. I didn't know if there was something else along with that. Great. Thank you so much. Again, congrats on the quarter and best of luck.

Scott Anderson (EVP and CFO)

Okay. Thank you, Kathryn.

Your next question comes from the line of Jerry Revich from Goldman Sachs. Your line is open.

Jerry Revich (Managing Director and Senior Equity Research Analyst)

Yes, hi. Good morning, everyone.

Anne Noonan (President, CEO, and Director)

Hi, Jerry.

Jerry Revich (Managing Director and Senior Equity Research Analyst)

I wonder if you could just talk about the potential for cost per ton, both in ags and cement, to come down for you folks in terms of the pace of inflation. What we're seeing in other labor-intensive industries is just improved productivity as turnover rates normalize and things generally normalize post-COVID and delivery of equipment and efficiency gains as a result. I'm wondering to what extent is it possible, based on the lead indicators that you track, that we could see unit cost inflation slow to the low single digit range over the coming quarters?

Anne Noonan (President, CEO, and Director)

I'll let Scott take the inflation and cost profile that we're looking at for 2024.

Scott Anderson (EVP and CFO)

You bet, Jerry. So when we think of cost, you're right. We see opportunity here to expand the margin in ags and bring down that cost. We've got a pretty aggressive playbook around operational excellence. But let me just tell you kind of on the inflation side of it, when you look at labor, last year, we were bumping up against that double digits. But we've got that model to come off, and now we're looking more in that 4%-5% for this year, which we think that's going to provide some opportunity for us. As you go through some of the other areas on energy, our diesel fuel, our hedging program has put us in a really good place. So we got favorability on that for next year. As a matter of fact, we've got 50% of our diesel fuel already hedged at $2.79 a gallon.

And if you compare that to an average of last year, about 320, you can see we got some favorability there. It would be easy for me. We use about 32 million gal a year. It'd be easy to come up with $6 million-$8 million in savings right there or a tailwind for us. So we've got some overall, though, when you think of cost, we do say coming from the high single digits% last year, really moderating down to that mid-single digits% overall is kind of where we're looking at. And that's just some of the big pieces there. I guess the last one I would mention is the supply chain cost. That's the one we're really watching closely. And as we get more into the Argos business, we'll get a better visibility around that. But right now, last year, that was double digits%.

When I say supply chain, I'm talking the repair and maintenance. I'm talking the equipment-related parts, the subcontracting. And that one's 25% of our overall COGS. So that's a big piece. And we're watching that one closely. Where last year, we were double digits, we're seeing that more in that mid to high single digits, maybe that 7% right now on an early view. So hopefully, that gives you a little context, Jerry, on where we're going. But definitely, ags margin expansion, the last two quarters, we've been focused on that, and we're carrying that in. We're going to be all over the cost coming into this year.

Jerry Revich (Managing Director and Senior Equity Research Analyst)

Thanks, Scott.

Your next question comes from the line of Mike Dahl from RBC Capital Markets. Your line is open.

Mike Dahl (Managing Director and Senior Analyst)

Hi. Thanks for taking my question. Anne, just back on the high-level bridge to the guide to put a finer point around things, can you specify what your assumed contribution is for Argos versus legacy standalone Summit and maybe specifically call out what some of those synergy quantifications were? Because obviously, you've got the $30 million in goodies from the synergies, but maybe just help us understand in a little bit more detail that.

Anne Noonan (President, CEO, and Director)

Yeah. Well, let me kind of give you the guide overall. So if we think about, we've talked about the markets being essentially flat on volume. So a lot of our, if you think about the synergies, the operational synergies, they're about $30 million. They're clearly not on the Summit side, right? So that side will be coming from, except maybe the SG&A and procurement would be more at the SSC level. But you're going to see it in cement and in ready mix. And if you think about cement margins being in the low 30s%, we have a lot of confidence in growing those through the OEE improvement and putting Portland limestone cement in. In ready mix, the ongoing fleet modernization completion gets to about 10%. We'll have opportunity to grow there.

So overall, if you just step back and look at the growth of our guide, exclude out the divestitures, you got a 4%-11% growth. You got $30 million in synergies, a big chunk going into the Argos side of the business, and then some, obviously, shared between the two. You should see the base businesses growing in that high single digit growth range in our guide. So I would say we're very confident in the 23%-24% margin at the end of the year coming off of 22%, which, as you recall, in our proxy, we actually had dilution in the first year. So we're very encouraged by the ability to deliver the synergies, have continued price flexibility, grow our ags. OPEX is what's going to drive, and improved contribution from green fuels will drive our Summit side of our business.

Hopefully, that gives you a little bit more color, Mike.

Mike Dahl (Managing Director and Senior Analyst)

It does. Can I sneak in a follow-up?

Anne Noonan (President, CEO, and Director)

Sure.

Mike Dahl (Managing Director and Senior Analyst)

I guess if I plug in the high single digits on the legacy Summit, it gets me to about $610 million, which is kind of below where you expect it in the proxy, even though you just beat on the quarter. So is that just your conservatism on volume? Because it sounds like you've got pieces in place for the price and margin initiatives.

Anne Noonan (President, CEO, and Director)

Yeah. So we are being conservative and guarded, I'd say, on volume. There is some upside there, but also remember pricing. So we only have first-half pricing, and we do not have any mid-year pricing in across the Summit platform. And as you know, Mike, we've been very strong at putting mid-year pricing in on aggregates. Our customers are accustomed to it. And cement, I believe demand will pick up in the second half, and we'll have some opportunity to go there also. So think about it as a volume and price upside, particularly on the Summit side.

Mike Dahl (Managing Director and Senior Analyst)

Thanks, Anne.

Anne Noonan (President, CEO, and Director)

Okay. Thank you, Mike.
