Presentation

Operator

Good day, and thank you for standing by. Welcome to the Q1 2024 Louisiana-Pacific Corporation Earnings Conference Call. (Operator Instructions) Please be advised that today's conference is being recorded. I would now like to hand the conference over to your speaker today, Aaron Howald, LP's Vice President of Investor Relations and Business Development.

Aaron Howald

Thank you, operator, and good morning, everyone. Thank you for joining us to discuss LP's results for the first quarter of 2024 as well as our updated outlook. My name is Aaron Howald, and I am LP's Vice President of Investor Relations and Business Development.
With me this morning are Brad Southern, LP's Chief Executive Officer; and Alan Haughie, LP's Chief Financial Officer. After prepared remarks, we will take one round of questions. During this morning's call, we will refer to a presentation that has been posted to LP's IR web page, which is investor.lpcorp.com. Our 8-K filing, earnings press release and other materials are also available there.
Today's discussion contains forward-looking statements and non-GAAP financial metrics as described on Slides 2 and 3 of the earnings presentation. The appendix of the presentation also contains reconciliations that are further supplemented by this morning's 8-K filing. I will incorporate those materials by reference rather than reading them. And with that, I'll turn the call over to Brad.

William Bradley Southern

Thanks, Aaron. Good morning, and thank you for joining us to discuss LP's results for the first quarter and our ongoing growth, innovation and efficient capital allocation. LP's Siding and OSB businesses got off to a strong start in 2024 by launching new products, gaining share in new construction, repair and remodeling and growing strategic partnerships with our customers, all of which contributed to outstanding results in the first quarter. I'm confident that both businesses are poised to build on these gains in the second quarter and beyond.
In the first quarter, LP generated $724 million in sales, a 24% increase over last year. LP earned $182 million in adjusted EBITDA, $116 million more than in Q1 of 2023. Leverage from growth in Siding and the combined effect of higher prices and record operating efficiency in OSB drove improved margins. With the completion of capacity investments in Houlton, Sagola and Bath, our strong balance sheet has allowed us to resume share repurchases consistent with our capital allocation strategy.
Alan will discuss our results in greater detail in a moment. But first, I'll provide the operational and strategic highlights for the quarter across our businesses. In the OSB business, commodity prices were meaningfully higher than last year, contributing $62 million in EBITDA. This is, of course, outside our control. However, I am proud to say that the OSB team made the most of the strong demand environment by operating efficiently and safely while delivering a strong mix of value-added Structural Solutions products.
For example, the OSB business achieved a record for operating efficiency in the first quarter, which helped boost sales by about 150 million square feet compared to last year. More than 75% of this incremental volume was Structural Solutions. More importantly, the OSB business delivered these results safely with a total recordable incident rate under 0.3. I also want to take the opportunity to thank the teams at our Peace Valley British Columbia and Maniwaki, Quebec mills for leading the way with outstanding safety, efficiency and cost control.
Siding revenue grew by 9% in the first quarter, which was the compound effect of 5% higher net selling prices and 4% higher volume. Prices were higher due to rapid realization of our annual price increase plus mix uplift, primarily from expert finish. Higher capacity utilization from increased sales volume helped Siding achieve a 25% EBITDA margin in the quarter. As a result, the Siding business exceeded the high end of our guidance ranges for growth and margin. The chart on the left of Page 6 shows normalized growth in Siding volume, Siding net sales and total U.S. Housing Starts with (inaudible) as the common baseline.
The 2024 estimate for Siding reflects the midpoint of LP's updated full year guidance, which Alan will get to in a moment. As you can see, the Siding business is backed with historic growth trajectory after the destocking cycle that normally follows the end of a managed order file. In fact, the midpoint of our full year guidance represents sales volumes above 2021's level and net revenue above 2022's all-time high. By contrast, Housing Starts reached $1.6 million in 2021. And if the current consensus is accurate, will have fallen by about 9% to $1.45 million in 2024.
Nearly 30% cumulative Siding revenue growth over a period of which underlying market contracted clearly demonstrates pricing power and share gains in the market we serve. The chart on right shows ExpertFinish as a percentage of overall Siding volume and revenue. Starting from 0 in 2019, ExpertFinish has grown to 9% of volume and nearly 14% of revenue in Q1 of this year. If you were able to join us at the International Builders' Show in Las Vegas, you saw our newly launched Brushed Smooth Trim and Siding, Pebbled Stucco Panels, Nickel Gap and many other new products, all of which should add to the ongoing price mix uplift of ExpertFinish and help drive growth in new residential construction and R&R.
Our Siding business is clearly back to our normal growth footing, and LP is leveraging the power of our specialized portfolio to drive additional growth and share gains. For example, we recently announced a strategic partnership with Lennar, one of America's leading and most respected homebuilders. Through this partnership, LP will provide Lennar with a uniquely broad array of sustainable Siding, Structural Solutions and OSB products. We also expanded our partnership with the Home Depot, extending the availability of SmartSide Trim to Home Depot stores nationwide.
These partnerships enhance our strategic customers' ability to build high-quality and beautiful homes for homeowners and make SmartSide available for more R&R contractors. This, in turn, leads to continued growth, share gains and innovation in Siding and OSB. I should mention that the impacts of the Lennar partnership, newly launched products in Siding and the meaningful increase in OSB prices late in the first quarter, had a relatively modest impact on our Q1 results. These factors will largely to be felt in the second quarter and beyond with continued growth, driving additional leverage in Siding.
Accordingly, while macroeconomic uncertainty remains, we are increasing our guidance for growth and margins in the second quarter and full year. With that, I will turn to Alan for more detail on the quarter and our updated outlook before we take your questions.

Alan J. M. Haughie

Thank you. As Brad said, this was a strong quarter. Higher market prices for OSB drove significant cash generation, while the leverage from increased volumes in both OSB and Siding delivered healthy incremental margins. EBITDA of $182 million generated $105 million of operating cash flow. And with the capacity investments in Houlton, Sagola and Bath behind us, LP returned $32 million of this cash flow to investors in the first quarter through dividends and resumed share repurchases.
The waterfall on Page 7 shows the year-over-year comparison for the Siding business. Average selling prices were 5% higher than last year, adding $15 million of EBITDA. Roughly 3 points of the 5 points are the result of robust realization of the annual price increase helped by our minimization of prebuy late last year. ExpertFinish and other recently launched products have also seen encouraging uptake with the resulting positive mix effects on price contributing the remaining 2 points of the 5 points. Sales volumes increased by 4% to 399 million square feet, which I should note is higher than any quarter of last year.
The bulk of 4% volume growth came from Residential Construction and Repair and Remodel customers. BuilderSeries, which is driving share gains with America's largest homebuilders, and ExpertFinish, our pre-finished Siding, designed through Repair and Remodel contractors, both delivered record quarters for volume and revenue. This volume growth added $15 million in revenue and $4 million of EBITDA. Now this is slightly lower incremental EBITDA margin than we might expect from additional volume, largely due to record ExpertFinish volumes.
As a reminder, ExpertFinish margins are lower than primed margins what they are for now. While they may be lower, they are improving. The addition of the highly automated Bath pre-finishing facility to LP's ExpertFinish network, in addition to other efficiency gains in manufacturing, contributed to a meaningful improvement in the margin for ExpertFinish compared to this time last year. And of course, as we grow ExpertFinish volumes, further improvements in utilization rates and manufacturing efficiency should continue this positive margin trend. As discussed on prior calls, we are continuing to invest in selling and marketing, incurring an incremental $2 million year-over-year from which we believe we are already benefiting. This is more than offset by the $4 million benefit from the nonrecurrence of last year's mill conversion investments.
Freight costs and raw material prices continue to moderate from last year's levels, with MDI resin being the largest single component of a $10 million EBITDA tailwind from improving raw material prices. And our unit costs for paint may have risen, substantial efficiency gains from more automated painting processes at Bath reduced unit paint usage more than enough to offset this. The only red bar on the waterfall is the $7 million of increased mill overhead. This is simply the addition of Sagola and Bath to the network as neither were fully staffed to operational in the first quarter of last year.
Both with Sagola and Bath now fully (inaudible) as demand grows to fill that capacity, we should see those costs more than offset by the high incremental margin of additional volume. So the $90 million of EBITDA represents a margin of 25%. We've often compared the Siding EBITDA margin over time to a rising sign wave with peaks at times of high capacity utilization and low investment and troughs at times of high investment and low utilization as that new capacity comes online. We believe that what we saw in the first quarter is entirely consistent with this principle with the business rebounding from last year's trough and growing towards a new higher peak as we fill recently added capacity.
Shifting to OSB on Page 8. The waterfall is once again dominated by price. Compared to last year, average selling prices were 38% higher, adding $62 million of EBITDA. I should point out that the commodity price gain of 51% is higher than the 25% increase in Structural Solutions prices, mainly because commodity prices start from a lower base. However, in general, OSB prices climbed significantly at the end of the first quarter and remained elevated through most of April until our recent pullback. Given the duration of our order files, higher prices at the end of the first quarter have been realized mostly in the second quarter.
Sales volumes were also higher in OSB, a record quarter for OEE, allowed production increases to meet stronger customer demand. And as Brad said, more than 75% of the incremental OSB volumes sold was in Structural Solutions, which accounted for 52% of total OSB sales volume, up 6 points from last year. So if you'll indulge me, let me use the data on this chart to briefly demonstrate the value of Structural Solutions in a different way. Using the price, volume and EBITDA data on this chart to compare commodity to Structural Solutions, you'll see that the selling prices for the incremental Structural Solutions volume, if you do the math, we're on average about $55 per thousand square foot higher, and Structural Solutions EBITDA per thousand square foot was about $25 higher than it was for commodity.
Of course, this analysis is imperfect as it's only the year-over-year incremental changes, not the entire population, but it does directionally demonstrate the incremental margin uplift that Structural Solutions delivers and therefore, it reinforces our strategy of ongoing specialization. As in the Siding business, deflation in raw material prices contributed $7 million of EBITDA. For OSB, the other bucket is mostly the nonrecurrence of last year's aggressive cost control efforts in the face of very weak demand and depressed prices at that time, including the deferral of most nonessential maintenance and capital work. And while this may have kept the business EBITDA positive a year ago and demonstrated an impressive operational flexibility, we are now back on a more regular footing for operations. As a result, we have resumed more normal maintenance spending.
The $90 million of EBITDA generated in the quarter, coincidentally, the same as the Siding business represents an EBITDA margin of 29%.
Slide 9 shows substantially improved year-over-year cash flow. The operating cash flow this year is almost equal and opposite to this time last year with an inflow of $105 million this year, compared with an outflow last year of $119 million. And this boils down to 2 obvious factors, higher EBITDA and significantly less working capital build. And when it comes to uses of this improved operating cash flow, the completion of the Sagola and Bath investments resulted in substantially lower capital investments this year.
So consistent with our stated capital allocation strategy, and as Brad stated, we're generating cash and have resumed share repurchases. Speaking of which, as of May 8, we have spent $50 million in share buybacks to find 2024, including the $13 million spent in the first quarter. And LP's Board of Directors has approved an increase of $250 million to our remaining authorization, bringing the total authorization for share repurchases to $400 million as of today. And with roughly $800 million in liquidity, LP has more than enough dry powder to support future growth and shareholder returns, which brings me to our updated guidance on Slide 10.
For Siding, the strong first quarter demand has continued into the second quarter and even accelerated. As a result, we now expect revenue in the second quarter to be in the range of $380 million to $400 million, representing revenue growth of somewhere between 20% and 25%. I'm sure you'll remember, and we can scarcely forget that the second quarter of last year represents the weakest comparable for the year and, therefore, magnifies the rebound somewhat. This incremental volume would sustain EBITDA margins in the order of 25%, resulting in EBITDA for the quarter of $95 million to $105 million.
Accordingly, we're raising our guidance for full year revenue growth by 300 basis points to a range of 11% to 13%, and increasing our full year EBITDA expectations to the $340 million to $360 million range for an EBITDA margin of around 23%. For OSB, if we assume OSB prices remain at current levels, we would expect EBITDA in the range of $125 million to $135 million in the second quarter. For the full year guidance, we're modeling, but not predicting cycle average for the second half of the year. As a result, our full year EBITDA guide of $315 million to $325 million is the sum of the first quarter actuals, the second quarter guidance and then the second half at cycle average, as defined on Slide 10. Basically the same method we introduced last quarter, but with updated numbers, obviously.
Assuming for simplicity that LPSA and corporate net to zero, this brings our full year EBITDA guidance to $655 million to $685 million, about $150 million higher than our previous full year outlook. So in summary, it was a strong quarter and a strong start to the year that leaves both businesses exceptionally well positioned to continue executing our strategy of growth, specialization and transformation. And with that, we'll be happy to take your questions.

Question and Answer Session

Operator

(Operator Instructions) Our first question comes from Kurt Yinger with D.A. Davidson.

Kurt Willem Yinger

I just wanted to start off on Siding. I guess if volume is kind of the biggest lever on margins, and we see kind of a sequential uplift Q2 versus Q1, What kind of constraints additional margin expansion versus what we just saw, I guess as you look into the back half as well based on the implied guide, anything to keep in mind from a cost of production or maybe SG&A perspective that we didn't kind of fully realize in Q1?

Alan J. M. Haughie

This is Alan speaking. Well, nothing really. There are a few product introductions, Brushed Smooth and then the [gap] Siding will be increasing the volumes of those and those will be slightly inherently less efficient than the primed -- current primed production. And we are growing ExpertFinish. And as we've said, the ExpertFinish margins are themselves lower than primed. And to be honest, we like to give ourselves, well, call it, the operating room to swing for the fences.
And if that means, as an example, adding additional selling and marketing spend, which we may choose to do or with this kind of volume growth, possibly accelerating some of the preparation for the restart of Wawa. This 23% EBITDA margin guide gives us the room to do that and still we believe, hit that commitment.

Kurt Willem Yinger

Got it. Okay. That makes sense. And then Second, just on the Lennar announcement. I was hoping you could talk a little bit more about what type of opportunities you see this opening up for Siding specifically? And we've kind of seen some testimonials around the business you do with them in the Midwest. I believe you guys do well here in the Mountain West as well. I guess how should we think about kind of what's incremental related to what you've announced?

William Bradley Southern

Well, the -- there's a significant piece of incremental volume over what we've done then just from a Siding perspective historically. And so basically, what's happening, Kurt, is we were assigned new geographies that we are currently servicing with our Siding portfolio. And that's pretty much across the country, but obviously, not every region, not every subregion was converted, but a significant amount of the volume was.
So the opportunity for us is just to expand the geographic reach, particularly our new construction products into the field, into distribution as Lennar, it comes in the main vehicle to drive demand for that BuilderSeries portfolio, so there's certainly a volume uplift that we're beginning to realize with Lennar orders, but also as we experienced a geographic expansion that this opportunity provides and it will provide for even more growth of BuilderSeries as we pick up accompanying bigger (inaudible) dealers that have to carry the product in order to service Lennar.

Operator

Our next question comes from Mark Weintraub with Seaport Research Partners.

Mark Adam Weintraub

First, congrats, obviously, a very good quarter. And in fact, I think a lot better than you had originally anticipated. And so I'm sort of wanting to get a little bit more color if possible. On the Siding EBITDA margin. I think you have been guiding something below 20% and you end up basically at 25%. What was different? What played out differently than you had expected?

Alan J. M. Haughie

I'll take this one. The answer is almost everything. Let me use -- pricing was certainly better in the sense that both -- in both, in terms of mix and in terms of the impact that I mentioned in my prepared remarks, with the effect of the prebuy. But also we've spent the whole of last year talking about carrying the investment of additional mills through into 2024. And the benefits of that showed in that when we had a minor uptick in volume, there was essentially no real change in labor to absorb that volume.
So we got -- at least during Q1, we got additional revenue at what I'll call throughput, revenue minus material costs because the labor was already in place. And so that's not necessarily an easy thing to manage or predict, but fundamentally, that's one of the features that happened in Q1, which is one of the collateral benefits of us doing all of that preparation for what we call "The upswing" through 2023. So that positioned us really well to make maximum value out of the revenue. We also had better-than-expected raw material performance. So pricing, efficiency, raw materials. So in other words, almost everything.
And when we were on the call 3 months ago, this was -- this trend was just beginning to emerge, but it was not fully apparent at that time. But it was certainly emerging, which I think we try to convey a degree of, let's call it, confidence in our numbers, but that obviously was ultimately very much justified.

Mark Adam Weintraub

Great. And obviously, the right way to go in terms of -- versus guidance, et cetera. Maybe just following up a little bit on Kurt's question. I mean you are embedding what would be a relatively sharp decline in margins in the second half. And you alluded to some types of actions kind of, I guess, prep work that might be entailed. Can you maybe give us a little bit more color on that? And -- or is there also a relatively good chance that we end up with some upside surprises we saw in the first quarter as we think about the second half of the year. Sorry, in the EBITDA margins.

Alan J. M. Haughie

The short answer is yes. The longer answer is that the one we just gave to Kurt. Fundamentally, yes, it gives us the operating room to swing for fences, and we're confident that we'll hit at least 23%. And that's fundamentally, Mark. So the answer is yes.

Operator

Our next question comes from Susan Maklari with Goldman Sachs.

Susan Marie Maklari

My first question is just on broader demand trends in Siding. Can you talk a bit about how the quarter came together. And this relative strength that you're seeing into the Spring, feels like it's a bit in contrast to what we're hearing in some of the other larger ticket discretionary type product categories. I guess, can you talk a bit about how much do you think is company-specific and relative to some of the new products and the initiatives that you have versus the broader Siding space? And how do you think about the sustainability of this as we go forward into the back half of the year?

William Bradley Southern

Yes, Susan, great question. So we feel really good, certainly given the guidance we've put in place for Q2 about the sustainability of this for the short term anyway, but let me tell you why I'm equally excited about the long-term sustainability of the growth. And look, I do want to caveat that, I believe in -- for our Siding order file, we're back into a normal cadence of seasonality. So it's going to be -- that's going to play in to the quarter-over-quarter type of comparisons.
But fundamentally, what's happened over the last 18 months or so are 3 things. One, new product development has been real, and we've launched products that our customers have been asking for the type of products. So Alan mentioned this, as far as the pricing, the success of those product launches from a demand standpoint has been resounding. And so that -- and those new products open up new opportunities for demand that wasn't there before. When you don't have smooth ExpertFinish and somebody (inaudible) smooth, you're locked out of that market. So that has expanded our market just through the new product development.
And keep in mind that in our world, ExpertFinish and BuilderSeries are still relatively new to what we're doing from a demand standpoint. So having access to the big national builders, with a BuilderSeries and then having a viable nationwide ExpertFinish product offering, it really creates demand opportunities that didn't exist in the business, say, 3 years ago.
Second to that is the work we have done in Repair and Remodel to establish contractor and distribution relationships in support of the go-to-market strategy for ExpertFinish. Repair and Remodel has been a relatively new endeavor for us. And in that space, it's still -- there are still one-step distribution regions where we have been underpenetrated and we've built out that infrastructure to a large extent last year, and now we're able to leverage that, and there's still opportunities there. That's why we've done what we've done geographically, putting these ExpertFinish facilities in market.
And then finally, we're just getting started with the big builder. The Lennar deal certainly is a watershed moment for us, but there's 20 other targets that we have that we're actively working on. And we see opportunities to continue to gain market share in that space as well. So it certainly feels very sustainable. Now just let me round off that answer by saying, and right now, for this year, shed has really not been a driver to incremental volume growth this year and kind of the way inventory situation worked out last year, so if we're expecting some pickup in shed, certainly over where we were the first 3 or 4 months of this year, the remainder of the year, which add a little bit of fuel to our order file as well because that has been a weak spot.
So we feel good about sustainability. There will be rocks in the road as we get maybe to Q4, Q1 next year, people begin to manage inventory with a little more aggressiveness as I approach year-end. But we feel good about what we saw in Q1 being sustainable growth, not just any kind of one-off trend.

Susan Marie Maklari

Okay. That's great color. And then just following up on Siding, does sales and marketing spend actually came in well below what we had anticipated? I guess, can you just talk about what drove that? And are you still expecting the $15 million to $20 million in marketing for the full year?

William Bradley Southern

Yes. And look, that's -- those costs are ramped up to -- you just can't turn the spigot on immediately. So programs get built and then executed as we get closer to the building season. And then as probably all companies that you cover face as we try to add salespeople. It's easy to budget for that. It's a little bit harder to find the talent, onboard the talent and start paying the salaries. So that's the sales organizational adds that we have in place have gone slower than we would have liked. And then from a marketing standpoint, we're building up to the spend levels that we've talked about on prior calls.

Alan J. M. Haughie

And that's essentially a more detailed version of -- I'm sorry, I've tried to give around EBITDA margin in the second half. Hopefully, we will succeed in spending the selling and marketing dollars that we are planning to do so, which would have a bit of a margin drag compared to Q2 of this year -- sorry, Q1 of this year, where so far, we haven't spent as much as you might have expected or we would have liked.

Operator

Our next question comes from Ketan Mamtora with BMO.

Ketan Mamtora

Congrats on a strong quarter. Maybe the first question, can you talk a little bit about sort of how big is BuilderSeries today? I would imagine, fairly small. But where do you expect it to be over the next, let's say, 3 years and similar for ExpertFinish, how big do you expect that to be as well?

Aaron Howald

Ketan, you're correct. BuilderSeries is smaller than ExpertFinish, on the order of a couple of percentage points of volume. How big we expect it to be remains to be seen, but there may be a hint of that in the earnings deck that Brad referred to earlier. ExpertFinish started at 0 in 2019, and it was 9% of revenue this quarter -- 14%, sorry, 9% volume, 14% of revenue. BuilderSeries is at a different price point. And so it won't have quite the same mix effect, but it is another example of new product development in the Siding business that reaches new customers in new markets. And we fully expect the take-up for that to continue to grow. And the good thing about BuilderSeries as we've mentioned before, it drags along a whole host of other highly profitable products as well. So it creates its own [hay] level.

Ketan Mamtora

Yes. No, that makes sense. And then, Alan, you talked about sort of ExpertFinish margins being below Primed for now, at least. So as we look out, and this is not a next quarter or 2024 question, but as you think about the next 2, 3 years, when do you think that relationship flips with ExpertFinish margin?

Alan J. M. Haughie

(inaudible) to be a softball, but I'm going to say, yes, in the next 2 to 3 years, I hope. That's reasonable if (inaudible) blend goal. Yes, there is still work to be done, and we're still in the process of automating that we have a highly competent leadership in that group making great strides. I mean the variable margin, as I said, which I'm not going to disclose at this point, but the variable margin that we earned on ExpertFinish in this first quarter was significantly high in the first quarter of last year.
And again, to sort of return to one of the earlier themes, we didn't bank on that when we gave our Q1 guidance. And so that aspect of the business actually performed slightly better in our Q1 report in performance than we expected. So we're making strides. But as you can imagine, it will be a situation of 2 steps forward, 1 step back. So we don't necessarily take all of the improvements in Q1 and kind of inject them in perpetuity. So it is an ongoing process of learning how to do this. But I'm delighted with the progress we're making so far.

Operator

Our next question comes from Mike Roxland with Truist Securities.

Michael Andrew Roxland

Congrats on a solid quarter. Just want to get a sense, can you talk about the degree to which you produced OSB through Siding, if any? Because I recall at your Investor Day in February, you mentioned some optionality to increase production of OSB should market conditions warrant. I think you mentioned 50% of your Siding mills had that capability, or ability to produce OSB. So given the run-up in OSB prices and more modest -- especially the more modest ramp in Siding capacity, I'm wondering if you took advantage of that capability.

William Bradley Southern

Yes. Let me speak to that strategically. So as you know, over a multiyear period, we've converted OSB mills to Siding. And the larger OSB mills that we've converted, we've intended to retain the ability to produce OSB. And the reason for that is when a new Siding mill comes online in our network, we don't typically have the immediate demand to fill the facility up.
And so while we not -- we may not maintain the ability of the OSB in the current mill we're converting, we do maintain it in our system. And so we retain that as a mechanism to basically cover the semi-fixed cost in the facility where we have staffed up for Siding production so that we have the plant and the network capability to take advantage of what happened in Q1 and what we foresee happening in Q2. And we're able to fill the idle time with OSB production.
So it is done primarily as a cost optimization, say, in our Siding business so that we don't have idle assets or idle labor costs waiting on the order file for Siding to improve. And just to ease any concerns there, and this will may go a little more detail on how that's handled internally, we transfer that OSB production to our OSB segment at standard cost. And so the revenue for that OSB is recognized in our OSB business.
But obviously -- and the OSB segment cost is a standard cost for manufacturing Siding. So we want to try to -- because we're trying to keep the segment revenue cleaned by product, not by location or manufacturing. So in the first quarter -- so we are making -- we did make OSB in our Siding network in the first quarter, it's -- in the big picture, it's a minimal amount. This is from memory, but most all of that production goes into the North Central region, where we don't have -- currently have OSB assigned capacity.
So we're selling into a market where we would not normally be present if we were relying only on our OSB network. And it is not opportunistic based on OSB pricing. It is opportunistic based on capacity availability in our Siding network that we -- so that we can cover the semi variable or semi-fixed costs, as I mentioned earlier, and keep the labor force active doing something constructively. So happy to take a follow-up question Mike, if I didn't cover the nature of your question, but I just wanted to provide kind of a little bit of a detail around why we do that strategically.

Michael Andrew Roxland

No, that's extremely helpful, Brad. Just one question if I could follow up on that. So the way it's booked is that using the cost structure of the Siding mostly, but you're capturing the revenue -- the revenue reported with the OSB, but using the cost structure out of the Siding segment.

William Bradley Southern

Exactly. The revenues and any margin gain over standard cost is recognized in OSB. And then -- but certainly, Mike, we get -- the reason we do it is that there is a cost reduction or whatever because it's the cost offset that happens in our Siding business that provides -- it helps the EBITDA margin in our Siding business because we're getting that cost transfer at standard, and that is helpful.
So it's a cost -- help in our Siding or EBITDA margin help in siding. And then depending on the pricing of OSB, it can be a significant add to our OSB EBITDA.

Alan J. M. Haughie

I also think that by virtue of doing this, we don't have to reconfigure the Siding network and the staffing as much as we would otherwise do, and we can -- the idea of the Siding business is it's a growth business. When we hire people at the mill, the idea is that you come and work at a Siding mill and the shift that never goes down and we continue to recruit people, and we like to try and stick to that. And then we can gain experienced crews, capable of then doing exactly what we just described happened in Q1, which is adding additional Siding volume and not needing to add shifts because the shifts are trained and capable and they can pump out volume when it comes in.
So it's got a great sort of collateral benefit to the future efficiency of the Siding business because it sets itself up for that success.

William Bradley Southern

Yes. I just -- that's a great point and just to add a little detail. So we spent -- on these mill conversions that we've experienced recently and the costs associated with that, there's a great deal of training that goes into those transitions because look, when you're manufacturing OSB, that is not an aesthetic -- there's not an aesthetic quality parameter within the realm of reason for OSB, it's highly a big part because of downgrade in a Siding mill. So the training that happens in those facilities is it's a major investment. So we're making a major investment in the workforce.
So just to be simplistic about it, what we don't want to do is convert a mill and then not have the Siding -- immediate siding volume to run the mill and have to lay -- do a shift for the staff reduction to make that demand. And so OSB helps us retain some consistency in operations at these facilities after we make these sizable investments (inaudible).

Alan J. M. Haughie

And on Investor Day, and (inaudible) meeting with investors and you guys personally, we'll talk about why we think the whole is greater than the some of the parts, if you use some of the parts analysis. This is one of the reasons that each business has -- can -- there's a symbiotic benefit being able to do this. That's one of the reasons why the whole is greater than some of the parts.

Michael Andrew Roxland

Got it. Great color. One last question just, and I'll turn it over. Do you recall then just when you look at your OSB segment, how much of the revenue or EBITDA came from running the Siding mills on OSB to accomplish that? And would it be fair to say that as you progress through the duration of this year, the contribution of the Siding mill should lessen as you run more Siding product itself?

Aaron Howald

Yes, Mike, I would say that the amount of the year-over-year volume increase in the OSB business enabled by OSB production in the Siding mills was pretty minimal. It was between 1/4 and 1/3 of the year-over-year increase. And so it has a positive impact, but not a dramatic one. I guess, I would characterize the Siding impact the same way. It helps us to be ready for the upside, but it's not a huge amount of volume and mostly the increase in the OSB business was enabled by the combination of very strong OEE, operating efficiency as well as a fair amount of overtime in those facilities. So the bulk of the uplift came from OSB. And obviously, that's where the benefit accrues as well.

William Bradley Southern

Michael, let me just add one level of detail to the answer to your question. We do tend to contract that volume out of Siding just because we want to know there's a market there. So typically, once we've done that for the year, that volume is pretty consistent quarter-to-quarter now. If we get into a situation where Siding demand requires full production, we can do some things in our OSB business to cover that contract volume. But it is -- it should be expected that we would run some OSB in our Siding system the rest of this year. Then we get to next year and we look at that volume and say, why do we need? But typically, we do contract that volume. Just to make sure we have a home for it, and we're not having to put all that volume on the open market.

Our next question comes from Steven Ramsey with TRG.

Brian Biros

This is actually Brian Biros on for Steven. First one on Siding, I guess just any commentary on the channel inventory there of the product SmartSide, ExpertFinish, BuilderSeries. Is it healthy for this time of year for the rate outlook? Or is this kind of maybe a tailwind to help 2H?

William Bradley Southern

The inventories -- look, it's hard to remember what normal was after COVID coming off of order file. But even with my memory, sales not being what they used to be. We are back to a normal seasonal pattern on inventories. And so I would characterize today's inventory levels as normal, but normal being a little high because distribution has certainly brought in products like ExpertFinish, in anticipation of a strong summer season. So typically, historically, distribution builds inventory beginning February through April, May and then the inventories work down until October time frame.
But we feel really good that the product is moving through. There's no strange order inventory build anywhere in the channel. But I just want to be transparent about that means probably a little higher levels than it will be in November, but healthy for the level of demand that we're experiencing in our order file. So we do not have concerns about any inventory build in the channel affecting, I mean, certainly next quarter, which we guided to.

Brian Biros

Okay. Understood. And then maybe secondly, on the Siding margins of, I guess, 23% now versus 20% prior, really a major jump sales guide going from $1.45 billion to, I think, $1.5 billion now. You've repeatedly stated before, volumes obviously have a major impact on margins. I guess how much of that margin raise here is volume and mix helping the sales or anything else of the kind of initiatives and better efficiencies at the plants and things like that?

William Bradley Southern

Volume is a huge -- production volume is a huge driver to these margins. Let's be clear. And so as we continue to kind of at least outperform our expectations around sales volume and lever that into incremental production in our facilities, there's tremendous -- that's very beneficial to our margins. And then as Alan mentioned, given the health of the order file, our sales -- our price increase that we implemented January went through really quickly and has held very strong, very -- has some stickiness to it. So we're confident there.
And then somewhat unexpectedly, the level of resin MDI, a price fall has been additive as well. So -- but look, any kind of long-term view of margin for this business is going to be primarily driven by our ability to get price, our ability to improve mix and our ability to run these facilities full or close to full. And just keep in mind, like Sagola is up. When we add -- when Sagola is up and fully running and functional and optimized out, that is a big Siding mill. So these Siding mills that we add to our system lower our average cost because of the scale they provide, similar things happening in Bath on ExpertFinish.
And so we're in a growth phase and have been for a while, where the incremental growth comes, can still come with incremental margin because of the efficiency that's inherent in these large mill conversions and ultimately inherent in us filling up the system.

Our next question comes from Sean Steuart with TD Cowen.

Sean Steuart

A couple of easy ones for you. With citing momentum clearly very much on track, any updated thoughts on Wawa in terms of timing and capital costs to move that project forward?

Aaron Howald

Yes. Thanks, Sean. The update is that we continue on a weekly basis to evaluate our expectations for demand growth. It's never a perfect process of timing new capacity additions to perfectly match demand, but it is something we evaluate very, very frequently and consistently. I think really, the only thing concrete we can give you is that certainly, our expectation is earlier than it was 6 months ago. And the more you see uptake of volume and the faster we build Sagola and the faster we build Bath, the sooner we're going to want more capacity.

Alan J. M. Haughie

Probably with no -- there was no impact on CapEx this year. You see that our guidance has stayed the same. So I mean nothing significant from a CapEx perspective this year.

Sean Steuart

Understood. Second question is just on OSB industry capacity growth. There's still a lot on deck in the next 2 to 3 years. And Brad, would be interested in any updated thoughts you have on the likelihood that all these projects come to fruition and constraints on bringing that supply into the market at the pace that's been suggested by all these announcements and capital constraints, labor constraints, other issues along those lines.

William Bradley Southern

Yes. I'll just say that in our own experience, too, it takes longer than planned initially when we talk about the complexity now getting permitting and some of the social issues related to mill locations. So I mean the -- and then secondly, the market has to be there, one would think for some -- for all of these to go forward as planned. So we're keeping an eye on it. We can't control, obviously, what our competitors do with capacity expansion. But I do kind of take the long view of some of these more -- ones that are on the board to have a lot of momentum behind them yet.
But there are a couple coming online. It's going to have some volume in the market later this year. And -- but we feel good about the rest of the year in our OSB business, and we'll manage our capacity to meet our customers' demand in the most efficient way we can. I don't want to speculate too much about what our competitors are going to do because I don't know for one thing, but I will say, so far, it's been -- it's taken longer than initially announced and planned on by all the folks that have tried to bring capacity online.

Operator

Our next question comes from Matthew McKellar with RBC Capital Markets.

Matthew McKellar

Could you provide any color on how much of the bump you're citing sales guidance for the year? You would attribute specifically to the partnership with Lennar, you announced last month and maybe the expansion of Trim at Home Depot, you noted versus a broader outlook for stronger sales across the business.

William Bradley Southern

No, I would say the -- both of those were in our thinking when we originally gave guidance back last quarter. And so we haven't really added -- because of those 2 things I mentioned in my script, we haven't added demand because of that. It's just what we're responding to is the overall strength in our order file up until last Friday, I think the last time we got a report. And that is -- that demand that we're feeling is across basically all sectors with a little bit of not so much in shed, as I mentioned earlier. It's just across the board, orders from distribution that is creating the optimism that we have about the outlook for Siding.
But we did not up it, just to be specific, the guidance increase was not because we signed a Lennar deal or we signed a Home Depot deal. Those deals are long time coming, and we have some visibility into that when we guided last quarter.

Our next question comes from George Staphos with Bank of America.

Lucas Michael Hudson

This is actually Lucas Hudson on for George Staphos, he's currently traveling. Congrats on the quarter guys. If you guys could just walk me through the Siding trends and how they vary between pro contractor and do-it-yourself along with home center and distributors, please?

William Bradley Southern

That was a little bit hard to understand the question, but let me say it back to you that so the different route to market or what differences are we seeing from a demand standpoint across those different routes to market. Was that the question?

Lucas Michael Hudson

Yes. Just the overall demand trends between a pro contractor, do-it-yourself, home center and distributors, please?

William Bradley Southern

Okay. So home center demand for the new products that we have put in place, particularly things like Trim, very good. Panel business, not a driver to incremental volume, but a strong basis for volume, which, by the way, most of our home center volumes to be clear is panel. So that's kind of reflective of what we're seeing in shed. For new construction, where we've had market access, it is strong. Where we are opening new regions as a result of the deals we've discussed, it's high percentage growth off of a low base. So a lot of opportunity there.
And then for Repair and Remodel, we feel really good about that, but that is kind of like one of these compounding incremental opportunities where as we add contractors and we add access to market through one-step distribution, but that kind of builds upon itself as far as compounding growth, so that certainly has represented in the ExpertFinish numbers, a key driver to the incremental volumes that we're seeing. So we take a step back and say, good new construction growth, both at the distribution and end-user area, good growth and Repair and Remodel at the contractor and distribution level there as well. And then for the home centers kind of steady as it goes, but not with new products, which are really moving well through the consumer retail channel.
