Greetings. Welcome to GMS Fourth Quarter Fiscal 2021 Earnings Conference Call and Webcast. [Operator Instructions] Please note this conference is being recorded.

At this time, I will now turn the conference over to Leslie Kratcoski, with Investor Relations. Leslie, you may now begin.

Leslie H. Kratcoski -- Vice President, Investor Relations

With that, I'll turn the call over to J.T. J.T?

John C. Turner, Jr. -- President and Chief Executive Officer

Thank you, Leslie. Good morning, and thank you for joining us today. I'd like to take a minute to recognize the outstanding contributions that Leslie has made to GMS over the last several years. Leslie has led our IR function with professionalism, class and dignity, and has advanced our relationships across the spectrum of the investment community. She also has been a key member of our leadership team and has been a consistent source of common strength throughout the years and in particular, this last pandemic year. She has been instrumental in the development and execution of our strategic goals and I think we all recognize that our IR capability is light years ahead of where we were when she joined us. Thank you, Leslie. All of GMS wishes you well in retirement. I'm excited now to welcome Carey into our IR role and our team. We are very lucky to have found a capable professional so familiar with our space and our investment community.

During this morning's call, I'll start with a review of our operating highlights and then turn it over to Scott, who will cover our financial results. I'll then share some closing thoughts before taking your questions. Starting on Slide 3, we delivered a strong finish to fiscal 2021 as evidenced by record levels of net sales, net income and adjusted EBITDA. Our entire team continued to effectively navigate what remains a very dynamic operating landscape. Through a sharp focus on execution, we successfully capitalized on opportunities created by strong residential market tailwinds and robust demand in complementary products to deliver solid results for the quarter even as we continue to face soft commercial market conditions, supply constraints and inflation. Despite these dynamics, our disciplined execution generated a 21% increase in net sales, including 17.1% growth organically.

The benefits of continued cost discipline and favorable operating leverage enabled us to improve SG&A and Adjusted SG&A as a percentage of sales for the fourth quarter in a row, while ensuring that we maintained the customer focus that continues to differentiate us in the market. As a result, adjusted EBITDA increased 43.5% and adjusted EBITDA margin rose 160 basis points to 9.8%. We generated positive free cash flow of approximately 80% of adjusted EBITDA and maintained strong financial flexibility, which was further enhanced with a senior notes offering and term loan repricing during the quarter. Our strong balance sheet and liquidity position enabled us to continue our focus drive for growth via both greenfields and acquisitions, which was meaningfully demonstrated with the acquisition of D.L. Building Materials in Canada and four greenfield openings in the U.S. during our fourth quarter.

In addition, after the conclusion of the fourth quarter, we entered into a definitive agreement to purchase Westside Building Material, one of the nation's largest independent specialty interior product distributors. This highly strategic, well-managed business will greatly enhance our footprint and provide another exceptionally strong brand offering in California, while also affording us entry into the Las Vegas market.

Looking at Slide 4. For the full fiscal year 2021, we also generated record net sales, net income and adjusted EBITDA. Net sales increased 1.8% year-over-year to $3.3 billion. We realized a 6.5-year percent year-over-year increase in adjusted EBITDA to $319.4 million and a 50 basis point improvement in adjusted EBITDA margin to 9.7% for the year. Our disciplined adherence to the alignment of our cost structure at the onset of COVID-19 enabled us to realize a 100 basis point improvement in adjusted SG&A as a percentage of sales.

We exited the year with substantial liquidity and our free cash flow generation of roughly 40% of adjusted EBITDA contributed to a net debt leverage at fiscal year end up 2.5 times, the lowest level since our initial public offering five years ago. I would like to share my appreciation for all our teammates who met and overcame the numerous challenges presented by the COVID-19 pandemic throughout this past year. My congratulations and thanks go out to the entire GMS team who made our fiscal 2021 results possible, remaining engaged, focused and proactive as we came together in support of our customers, suppliers, communities and each other. At the same time, I would like to extend our gratitude to our customers for entrusting their business to us and to our suppliers for their ongoing partnership as they have both faced their own challenges in navigating the unprecedented circumstances throughout this period. We also express our thanks to our shareholders for their ongoing confidence and support.

With that, I'll now turn it over to Scott to provide more perspective on our financial results for Q4. Scott?

Scott M. Deakin -- Vice President, Chief Financial Officer

Thanks, J.T., and good morning. Before presenting our detailed results, I will note that the comparisons of our fourth quarter fiscal 2021 results to the prior year includes comparisons to March and April 2020. These periods featured widespread shutdowns and far ranging uncertainty, resulting in arguably the most difficult and drastically impacted months for us during the COVID-19 pandemic. While these dynamics were considered in our previously communicated fourth quarter outlook and clearly had a favorable impact on our year-over-year growth rates, it was the outstanding execution by our team and their commitment to our customers that drove our outperformance.

Specifically, looking at Slide 5, net sales for the fourth quarter increased 20.9% to $932.2 million, exceeding the outlook of low double digits provided on our Q3 earnings call. These gains collectively resulted from strong residential end markets, favorable pricing across product categories, the acquisition of D.L. Building Materials and as noted, COVID-related weakness during the prior year quarter. From an end market perspective, in the U.S., for example, residential sales showed considerable strength and were up double digits on both higher volume and price, while commercial sales which had continued to be sluggish from a volume perspective, were up mid single digits due to higher pricing and significant COVID-19 related volume weakness last year.

Excluding $15.8 million in acquisition related revenue and $13.7 million of favorable foreign currency translation, organic net sales increased 17.1%. As there was one more selling day in the fourth quarter of fiscal 2021 in the same period a year ago, net sales and organic net sales on a per day basis were up 19.1% and 15.3% respectively. As I review product segment performance, it's important to note that for all product segments year-over-year sales were up as a result of both higher volumes and higher combined price and mix. I'll also note that the impact of foreign currency translation has been excluded from the price mix component of the organic growth rates we have provided.

Wallboard sales of $376.9 million increased 6.6% year-over-year. On an organic basis, net sales of wallboard were up 13.3% comprised of a 9.8% volume increase and a 3.5% improvement in price and mix. In light of our response to supplier pricing actions over the past several quarters, our average realized wallboard price increased sequentially in each month of the quarter with the fourth quarter average of $329 per 1,000 square feet, up 5.3% from the third quarter and up 6.8% from where we ended the second quarter, which notably coincide with the first of the most recent series of supplier pricing actions back in October.

Ceilings sales of a $121.3 million increased 9.1% or 7% on an organic basis, due to a 1.8% volume increase and 5.2% in higher price and mix. Steel framing sales of $143.3 million increased 24.2% or 21.4% on an organic basis as a result of 7% higher volumes and 14.4 in higher price mix reflecting the upward movement in commodity steel prices, our realized steel pricing increased 16.8% sequentially from the third quarter with sequential increases in each month of the quarter. Sales of complementary products which we formerly refer to as other products were $290.7 million, increasing 31.4% year-over-year. On an organic basis, sales were up 25.4% due to strong volume demand and pricing in multiple product categories, our execution and strategic growth initiatives to increase complementary product sales and strengthen our Canadian business, for which complementary products comprises a larger portion -- excuse me, larger proportion of sales.

Gross profit of $293.9 million increased 16.8% compared to the fourth quarter of fiscal 2020. As expected, gross margin declined from 32.6% a year ago to 31.5% for the fourth quarter of fiscal 2021, primarily due to unfavorable product mix as total wallboard comprised a lower percentage of our sales as compared to a year ago and within the Wallboard segment, residential comprised a greater percentage of our mix. In addition, we experienced a typical lag associated with passing through rapidly rising wallboard prices as we saw this quarter.

Turning to Slide 6. Adjusted SG&A expense as a percent of net sales of 21.9% improved 260 basis points year-over-year. Approximately 100 basis points of benefit was realized operationally from continued discipline cost containment and productivity initiatives. While the remaining 160 basis points of improvement was a result of favorable leverage from higher pricing broadly across our product lines. In summary, fourth quarter adjusted EBITDA of $91.2 million increased 43.5% from the prior year quarter and adjusted EBITDA margin improved 160 basis points to 9.8%. This represented an incremental adjusted EBITDA margin of 17%, which is in line with the higher end of the previously provided 10% to 2% outlook range.

Turning to Slide 7. We generated free cash flow of $72.8 million or 80% of adjusted EBITDA in the fourth quarter. This was a decrease from unusually high prior-year quarter, principally due to the company's significant efforts to preserve liquidity at the end of fiscal 2020 in response to the COVID-19 pandemic, as well as proactive inventory build in this year's fourth quarter in advance of the expected manufacturer price increases and to ensure product availability for our customers amid increasing supply constraints. As J.T indicated, free cash flow for the full year fiscal 2021 came in at 40% of adjusted EBITDA, and we maintain our through-the-cycle objective of generating free cash flow range of 40% to 50% of adjusted EBITDA.

Capital expenditures totaled approximately $12 million and $30 million for the fourth quarter and full year fiscal 2021, respectively. Looking forward, we currently expect cash, capital expenditures to fall within a range of $30 million to $35 million in fiscal 2022. Our strong free cash flow contributed to a reduction of our net debt leverage to 2.5 times at the end of the fiscal year from 2.9 times as of the end of the third quarter. As of April 30th, we had $167 million of cash on hand and an additional $453.8 million available under our revolving credit facilities, affording us ample resources for the ongoing pursuit of our strategic growth priorities.

Moving on to Slide 8. I'd like to take a few moments to review the debt transactions we undertook during the fourth quarter to further optimize our already strong and flexible capital structure. In April, we issued $350 million of eight-year senior unsecured notes bearing a 4 and 5 eights annual coupon. Proceeds of this issuance were used to repay a portion of outstanding borrowings under our secured term loan facility, which as of April 30th had $509.7 million remaining outstanding. Simultaneously, we amended our term loan facility to reduce the interest rate to LIBOR plus 2.5%, representing a 25 basis point improvement.

The senior note issuance enabled us to lock in attractive fixed rate unsecured debt for eight years, a lengthening of our weighted average debt maturity and it provides a more balanced term structure to our maturity ladders out to 2028. This transaction also freed up additional secured term loan capacity for potential use in the future. After giving effect to these transactions, we anticipate incurring approximately $55 million of interest expense in fiscal year 2022. As a final note for modeling consideration, we anticipate the normalized cash tax rate in our calculation and presentation of adjusted net income for fiscal 2022 to be in a range of 24% to 25% based on expected business and income mix.

With that, now me let me turn the call back over to J.T before we open the line for questions.

John C. Turner, Jr. -- President and Chief Executive Officer

Thank you, Scott. If you turn to Slide 9. While our tactical execution in fiscal 2021 was necessarily focused on overcoming the unprecedented challenges of the COVID-19 pandemic, we nonetheless remain relentlessly committed to our strategic growth priorities of expanding share in core products, growing our complementary products offering, platform expansion and improved productivity and profitability. Our fiscal 2021 progress on these four initiatives is evident on several fronts.

First, expanding share in core products, particularly in geographies where we are under penetrated. Specifically, our actions which we're well under way prior to the pandemic to redeploy resources and increased penetration in residential construction in those geographies where we traditionally had less exposure enabled us to generate higher wallboard volumes year-over-year and provided an offset to the continued softness in commercial construction. In ceilings, we bolstered our distribution network throughout fiscal 2021, securing additional arrangements in several new markets, while strengthening existing arrangements in several others. As such, we believe we continue to expand share in both the Mineral Fiber and Architectural Specialty segments of the market, as evidenced by our sales levels compared to available market data.

Next, to diversify and profitably expand our product offering. We are focused on growing select complementary product opportunities outside of core products. Our multiple initiatives in both the U.S. and Canada are bearing fruit, as evidenced by 10.6% year-over-year growth in this segment in fiscal 2021, with positive year-over-year growth four quarters in a row despite the negative impacts of the COVID-19 pandemic.

Third, we are expanding our platform through accretive acquisitions and greenfield opportunities, while maintaining balance progress in debt reduction. During fiscal 2021, we opened six new greenfield locations in the U.S. We also acquired D.L. Building Materials for approximately $40 million, providing entrance to the important Ottawa-Gatineau market in Canada. These moves enabled us to extend our geographic presence to four new and attractive markets, including our first location in the province of Quebec. At the same time, with the strength of our free cash flow, we reduced our net debt by over $75 million in fiscal 2021. Our momentum in platform expansion continued into May, when we announced the signing of a definitive agreement to purchase Westside Building Material, one of the largest independent distributors of interior building products in the U.S. for $135 million. This exciting combination, which through 10 locations, expands and enhances our presence in multiple California metro areas and marks our entry into the Las Vegas market is expected to close next month.

And finally, to ensure that we deliver our best-in-class customer experience while continuing to drive productivity and further profit improvement, we are leveraging our scale and employing technology and best practices. We made significant progress in the deployment of our e-commerce platform in fiscal 2021, with most of our subsidiaries driving growth in customer accounts, online payments and proof of delivery, and our further deployment of business intelligence capabilities is putting actionable real-time data and insight into the hands of our field leaders. Finally, our 100 basis point improvement in adjusted SG&A margin and 50 basis point improvement in adjusted EBITDA are a testament to our successfully driving profitability.

Before making my closing remarks, a few thoughts about our first quarter outlook. We currently expect to generate year-over-year sales growth of approximately 20%, similar to what we realized in the fourth quarter as we expect a more difficult year-over-year comparison to be largely offset by higher benefits of pricing on net sales. In terms of profitability, we expect a continuation of pressured price cost dynamics, particularly in wallboard. As a result, we currently anticipate realizing a gross margin similar to the 31.5% realized in the fourth quarter and coupled with SG&A leverage and incremental adjusted EBITDA margin in the range of 10% to 15%.

Looking further out in fiscal 2022, the trajectory of inflationary pressures and supply constraints as well as the effect of those on our results in later quarters becomes more difficult to forecast. Nonetheless, we believe there is a fundamental support for continued strength in residential construction and while timing remains uncertain, early but encouraging indications of improvement in commercial construction are emerging.

Turning to Slide 10. In closing, GMS is well positioned for the long-term. As the North American market leader in the distribution of specialty interior construction products, we enjoy significant scale advantages, employ a differentiated service model and embrace an entrepreneurial culture. All three combined are enabling us to successfully execute for all of our stakeholders. At the same time, our strong free cash flow generation, balance sheet and liquidity provide not only near-term advantages in what remains a very dynamic operating environment, but enable us to pursue the long-term growth opportunities that makes this business so attractive. I am confident that our teams continued drive to execute the business and our strategy position us to generate value for our shareholders well into the future.

Rob, we are now ready to open the call for questions.

Questions and Answers:

Operator

[Operator Instructions] And our first question today is coming from the line of Keith Hughes with Truist Securities. Please proceed with your questions.

Keith Hughes -- Truist Securities -- Analyst

Thank you. A couple of questions. First on your commentary on commercial demand and some of the positive signs. When do you think some of the bid activity you're discussing, when do you think that will actually show up in a meaningful shift in shipments?

John C. Turner, Jr. -- President and Chief Executive Officer

Well, the larger projects, Keith, is still out probably into calendar 2022. We're starting to see some remodel activity kick in and we're hearing from other participants in the market, not necessarily in our exact space, but other participants in the market that they're seeing their pipelines fill back up from a remodel perspective and then you're seeing that with the ABI and Dodge just came out with their Momentum Index and the Dodge starts numbers look to be improving. So I think the larger projects are probably still in '22. But as you know, two-thirds of our business is remodel. So we think that we might see some green shoots here later in our in our fiscal year, maybe Q4 of our fiscal year.

Keith Hughes -- Truist Securities -- Analyst

Got it, OK. And regarding the -- your revenue expectation for the July quarter, the first quarter, how much will the acquisition add to that if at all, the Westside side acquisition? Or is there going to be too lesser [Phonetic] to be meaningful?

John C. Turner, Jr. -- President and Chief Executive Officer

So we're not -- we didn't put any numbers in here yet for Westside. So what we're giving you is ex Westside for the quarter.

Keith Hughes -- Truist Securities -- Analyst

Okay. And final question. I'm sorry, go ahead.

Scott M. Deakin -- Vice President, Chief Financial Officer

I was just going to add. In the release we talked about the size of that acquisition. We're talking about maybe a month of sales within that accretive to that 20% we already talked about.

Keith Hughes -- Truist Securities -- Analyst

Okay. And then the accounts receivable was up a good year-over-year. If you could talk about that, what's going on there?

Scott M. Deakin -- Vice President, Chief Financial Officer

Look, I think it's just really the overall trends of the business being up as much as it's been. Collections have been really good. Bad debt expense has been really tempered and tamed, so we haven't seen any increases there. It's really just the dynamics of the cycle of revenue that we're facing. And I don't think there's anything to be concerned about, its Just really related to what we're seeing on the demand side.

Keith Hughes -- Truist Securities -- Analyst

Okay, thank you.

Scott M. Deakin -- Vice President, Chief Financial Officer

I was just going to add to it. Overall, if you look at our overall working capital as a percent of sales, we're still in that same 17-ish% sort of range that we've been operating at. So the netting across accounts receivable, inventory accounts payable, etc., is all consistent with prior trends.

Keith Hughes -- Truist Securities -- Analyst

Okay, thank you.

John C. Turner, Jr. -- President and Chief Executive Officer

Thanks, Keith.

Our next question is from the line of Mike Dahl with RBC Capital Markets. Please proceed with your questions.

Chris -- RBC Capital Markets -- Analyst

Hi, this is Chris [Phonetic] on for Mike. Thanks for taking our questions. Just touching on the the margin outlook for this year, obviously you're expecting some additional pressure this next quarter. But I was wondering if you could maybe give us some additional color on your thoughts around the moving pieces, whether it'd be price costs or the residential mix pressures, and how that evolves through the year and whether you think kind of SG&A would be able to provide enough of an offset to keep gross margins moving higher this year?

John C. Turner, Jr. -- President and Chief Executive Officer

Your last question was would SG&A help our gross margins move higher this year. I think, you mean, yeah EBITDA margin.

Chris -- RBC Capital Markets -- Analyst

EBITDA margin, yeah.

John C. Turner, Jr. -- President and Chief Executive Officer

You know, our team has done a fantastic job and I think we're well positioned from a cost perspective to continue to do that moving forward. There is some inflationary pressures out there, obviously. Fuel is more expensive than it was prior year. We expect labor to tighten up through the year as well. But all that being said, our guys are really doing a great job. Our whole team is very productive. And we've invested heavily in technologies and other things to help us be better from a productivity perspective. So I think we will continue to do well on the cost side.

I think that the reason we don't talk much out beyond this quarter from a gross margin perspective is the fact that we're dealing with some interesting environments for inflation with steel doing what it's doing, and originally I think a month or two ago everybody thought maybe steel would settle back down toward the back half of the year, now we're hearing maybe that's not going to be the case. In wallboard, the industry just announced and implemented another increase in June, so we continue to chase that and that's really -- you hear us talk sequentially, mean sequentially our pricing is up really nicely and is continuing into this quarter. The issue is and so is the pace of price increases from the manufacturer. So if that settles down a little bit, I think like we said last quarter, we fully expect to catch back up and end up with a gross margin that's closer to our long-term average. But at the moment, we're just chasing things up on that side. So I think that we're doing a nice enough job on the bottom line to keep making improvements over time. And we've stated the long-term objective is to breach the 10% number on an EBITDA basis. And I think that everyone here is aligned in that objective.

Chris -- RBC Capital Markets -- Analyst

Got it. That's helpful. And then on the sales guide for next quarter, the 20%. Anyway you could help us with the building blocks there in terms of what's being driven by volume and price and what's your assumptions behind residential versus commercial growth?

Scott M. Deakin -- Vice President, Chief Financial Officer

Similar to what we saw in this last quarter, you're going to see a pretty heavy influence from price and mix, I'd say in the ballpark of probably 75% of that on an order of magnitude basis is going to come from price and mix and then the remaining portion of it is combined volume and FX, of which -- of that is probably two-third volume, Just as were up building blocks and orders of magnitude of the drivers.

Chris -- RBC Capital Markets -- Analyst

That's perfect. Thanks for that.

Operator

Thank you. Our next question is from the line of Matthew Bouley with Barclays. Please proceed with your questions.

Matthew Bouley -- Barclays -- Analyst

Hey, good morning. Thanks for the question. Congrats on the results. Can I ask about pricing power, I guess in residential specifically because clearly manufacturer price increases are pretty widespread here in wallboard and you're passing price along, although it sounds like there is a bit of a lag -- to the extent the big builders are trying to leverage their purchasing and you got smaller builders just take some challenges across the basket of building materials. Are you finding that the receptivity to your own passing of price is sufficient effectively? Thank you.

John C. Turner, Jr. -- President and Chief Executive Officer

When I mean sufficient, we'd like it to be faster. How about that. Sufficient, I would say in that we still believe that once the price increases are allowed that we will again achieve the types of gross margins that we're used to. On the other hand, it's never sufficient to be trailing prior year margins. So I think that it is the market based upon what we're showing sequentially in absolute pricing. And remember, our pricing is also a blended mix of all of our Board. So you're having the negative impact of the residential mix in that price is it inflates. So we're still showing really nice sequential improvement and continuing into this quarter.

So the answer to the question is, we're seeing it happen. We're certainly leading it in that respect and we're also being the partners with our customers. I mentioned that I think on the last call and I've mentioned that in several other individual calls. We have to be good partners with our customers, right? I mean, they also have the -- have to have the ability to plan their business and they have to have the ability to plan their pricing. So fortunately we are strong enough to be able to weather a month or two of increases before we pass them along. But that's in essence to the pace that this is happening in three months, six months, it's all -- the pricing is in.

Matthew Bouley -- Barclays -- Analyst

Got it. No, that's really helpful, J.T. Second one on the gross margin side, the mix impact, specifically just with better resi versus commercial. Just any ability to put some numbers or just elaborate on that. Just what that headwind looks like? Because, obviously, what I'm getting at is to the extent some of these green shoots you're seeing in commercial do manifest in better volumes later this year into calendar '22, what the kind of benefit to the margin would be from commercial recovery? Thank you.

Scott M. Deakin -- Vice President, Chief Financial Officer

I think, we stick to it in generalities. I mean, obviously, we gave you some indication leading into this quarter that we are going to be down at roughly 1 point based on some of those dynamics we are seeing. We're talking about it being consistent for the first quarter. Generally, as we talk about margins, we generally try to guide toward EBITDA being the better indicator between resi and commercial because the operating dynamics of serving the commercial versus the residential market. So on balance, as that starts to -- as commercial start to come back, we might see some general improvement on it and given the timing J.T talked about, that's not likely to be a significant first quarter impact, but as you go later in the year, we'll start to see a little bit of improvement in the gross margin side, offset by higher operating cost, but still get to a solid and positive EBITDA number overall. So I know those are generalities, but those are some of the dynamics that we're facing.

Matthew Bouley -- Barclays -- Analyst

Got it. That's helpful. Thanks, Scott. And thanks, J.T.

John C. Turner, Jr. -- President and Chief Executive Officer

Thanks.

Our next question is from the line of Kevin Hocevar with Northcoast Research. Please proceed with your questions.

Kevin Hocevar -- Northcoast Research -- Analyst

Hey, good morning. Nice quarter, everybody. Wondered if you could comment -- on the SG&A side you guys called out, I think 160 basis points of -- 260 basis points of leverage, a 100 basis points due to kind of operational cost containment and another 160 due to favorable leverage to pricing. So I'm wondering if you can kind of give us some color on how this evolves? Obviously, it seems like pricing continue to have momentum. So does that even get better, that 160 basis points that's benefiting from pricing as wallboard steel, all these other things keep seeing more pricing flow through? Just trying to think about how to think about that SG&A leverage, potential here this year?

Scott M. Deakin -- Vice President, Chief Financial Officer

The best way to do it is to -- if you focus on, or J.T. talked about in terms of the relative drivers of growth, its a little bit different, a tougher compare quarter-over-quarter on a volume basis, but we've got higher pricing drop-through on that. So if you take that leverage impact, if we've got that sort of 100, 160 sort of order of magnitude this last quarter and you in factor in a little bit more pricing in the first quarter, I think you'll see the relative impact of that drop-through we'll see in the first quarter. I mean, generally on an operating basis we're still seeing tight discipline on the operational side of our expenses. We're seeing some increases in fuel. We're seeing some as expected increase in compensation costs, salary cost, those types of things as people come back into the workforce to support what we're seeing on the revenue side. And then we're seeing some things, some operational expenses and things like insurance and the like. But generally we're still keeping that take discipline on our expenses on the operating side, so they have that favorability from a leveraging effect on the price side should be pretty strong positive going into the first quarter as well.

Kevin Hocevar -- Northcoast Research -- Analyst

Okay. And then, I know product had been -- supply has been constrained, lead times are extended on all over the place. How is that -- is there any improvements being seen in just product availability or is it just as tight as it's been for the last several months?

John C. Turner, Jr. -- President and Chief Executive Officer

Well, certainly in steel I think it's actually going to get a little worse as we move our way through the summer and then hopefully it frees up a little bit as we get into the fall. Wallboard is about where it has been. I guess, I would say that throughout this entire series of supply chain disruptions, really all kinds of products, right? I think that you're seeing the leaders in this space be able to weather the storm and get the products that we need to support our customers. You're also seeing us use our balance sheet in a way that allows us to have product available for our customers. That's what they would expect. When we talk about scale advantages, these are the times to leverage that and to use that and to demonstrate to your customers what you mean by that. So I think that we're doing a pretty good job. And I think that anything we are experiencing, I would expect others to be experiencing in a worst way. So while I don't see it getting a lot better, I don't see it getting a lot worse other than maybe steel. And steel is just going to continue to extend, the lead times are going to just continue to extend and the price is going to continue to to go up at least through the summer.

Kevin Hocevar -- Northcoast Research -- Analyst

Okay, got it. Thank you.

Scott M. Deakin -- Vice President, Chief Financial Officer

Thank you. The next question is coming from the line of Trey Grooms with Stephens. Please proceed with your questions.

Trey Grooms -- Stephens -- Analyst

Hey, good morning. Thanks, everybody.

John C. Turner, Jr. -- President and Chief Executive Officer

Hi, Trey.

Okay. First one from me is on the wallboard pricing. It's sequentially up nicely. Scott, you gave us a number there for the end of the quarter, I think was $329. And I'm sorry if I missed this. But did you guys give us any or could you give us maybe some, maybe a little more clarity around how you're thinking about the next couple of quarters on wallboard pricing? I mean, there was this June increase you know that you talked about. You're implementing the April now. So I guess is it fair for us to assume that from a pricing standpoint on wallboard specifically, that we could see something similar continue from a pricing standpoint over the next couple of quarters as you work this through and kind of catch up on that front?

Scott M. Deakin -- Vice President, Chief Financial Officer

So we talked about the average for the quarter at that $329 number. I can tell you we ended the quarter at $333. So progressively working up over the course of the quarter. And I think just given all the dynamics, you can expect that into May and June, we've seen further increases from there. Probably premature to give you anything. Frankly, we don't know exactly that will shake out past this quarter and into future quarters, but all of the same dynamics are continuing. And to the prior question and J.Ts. answer to it, the acceptance of the market around it, the continued resolve from the supply side in driving those actions in the marketplace continue to be there. So I think we'll see those trends along those general lines of progression continue.

Trey Grooms -- Stephens -- Analyst

Okay, fair enough. And then I guess on the complementary, I mean, this has been a big focus of yours, but clearly outperforming there. Can you talk about where you're seeing specific strength, market share gains within that kind of category there of complementary?

John C. Turner, Jr. -- President and Chief Executive Officer

We've been very strong in Canada and in the U.S. So lumber is -- and fire treated lumber, in particular commercial lumber packages, believe it or not, while commercial is down, it's still something that we've been focused on here in the U.S. So lumber, we've experienced not only nice unit growth, but of course the very, very high pricing that's going on in lumber over the course of the last year. Insulation, we continue to do better in insulation. We've had a focus on residential insulation, although we can't get as much as we could sell, quite frankly. That's one of the areas that's more supply constrained than anything. I guess the good news for us is its still in total, not a massive number for us, but we continue to try to build that business and we've been doing very well on insulation.

Roofing in Canada, great performance by our team in roofing up in Canada as well. And then tools and accessories, we continue to push hard to be the choice of -- to supply tools into our tradesman hands, right? Our smaller contractors and even the larger contractors that are in the tool buying business, the accessories buying business, things like fasteners and screws and all the finishing pieces that have to go into what we sell. All of that is doing very well. So I would just give you those categories as the primary drivers.

Trey Grooms -- Stephens -- Analyst

Thank you. Our next question is from the line of David Manthey with Baird. Please proceed with your questions.

David Manthey -- Baird -- Analyst

Hi, good morning, everyone. Most of my questions have been answered here, but maybe you could address the supply and demand dynamics within some of the non-res categories that you're thinking about. J.T., you mentioned the outlook for steel over the next six months and I'm just kind of wondering what your assumption for demand trends are in that outlook? And then on the ceiling side, is there any chance that we see one of these situations where everyone assumes that there is not going to be great demand and then inventories are thin and demand comes back and there is supply shortages. Anything you can help us in terms of that supply and demand dynamic as we roll through the summer?

John C. Turner, Jr. -- President and Chief Executive Officer

I mean, I still expect commercial. I mean, we see commercial down in volume prop this quarter. We're still rolling over kind of that COVID effect. But as you go forward, as we mentioned, we expect the whole comp to get harder on a volume basis because the recovery was beginning coming out of COVID, but those products primarily commercial from volume perspective. If we see any growth at all, low single digits, probably still the opportunity to see some decline in low single digits. But the prices are definitely up, with steel being up dramatically and going to continue to be up dramatically, lead times extended on steel. So I don't think swing a point or two around zero. And that's probably what you're looking at for volume for the next couple of quarters anyway and then improving after that.

As far ceilings go, we had a big explosion in demand and in fact spectacular, but you'll have to -- you have to ask Armstrong [Phonetic] in USG if they're prepared because from an inventory perspective, we're not off the gap. I mean, we're on the gap on inventory and we want to have it and we want to be able to sell it and fulfill our customers' needs right now. So we're not in a position where we would be caught, let's say, in a bad way from an inventory perspective. As Scott said, as a percent of sales, all total working capital is right about where we've kept it over the years and even with higher sales. So we're going to continue to focus on that and be the best distributor-supplier to our customer base and try to make it a little easier on them as they go through. You can imagine if its difficult on us trying to get material, imagine how difficult it is for the contractor to get material right now. So we'd like to be the guys helping them.

David Manthey -- Baird -- Analyst

Okay, thank you. And second, when you talk about the pressured price cost dynamics, I understand the dynamic environment that we're in right now. But what is the glide path looked like? I mean, how long do these commodities have to stabilize in price for you to catch up on the gross margin side?

John C. Turner, Jr. -- President and Chief Executive Officer

We're pretty much caught up on everything other than wallboard. So, I mean, if you were to decompose our gross margin, I mean, we're really -- we're really OK everywhere other than wallboard. And wallboard is not really all that terrible is just we're selling less of it as a percentage of sales than we are selling everything else. And as I've said before, it's three months to six months. Three months probably on the commercial side, closer to four to five to six months on the residential side to push it all, all the way through. But if you look at what Scott just said, $333, we are 3 -- I think our Q2 last year was $308 and now we're exiting at $333. That's a fair amount of increase and I think you'll continue to see us move on that kind of trajectory until the increases stop. And when those increases stop three months to four months later, you'll probably see us be right back up into the normalized gross margin range as we get the price into the market.

I don't see any big impetus to have the prices reverse dramatically in wallboard. On the other hand, steel is a commodity and lumber is a commodity that moves around a lot more aggressively, let's say. So I can't tell you what's going to happen with lumber and steel. But I certainly think at some point in times the steel situation will resolve itself and you will see that price come backwards, not in the near term.

David Manthey -- Baird -- Analyst

All right. Sounds good. Thanks, J.T.
