博伊西卡斯凯德 (BCC) 2026财年第三季度业绩电话会：销售额增长8%，第四季度业绩指引

核心要点

• 博伊西卡斯凯德（Boise Cascade）2026年第三季度综合销售额同比增长8%至18亿美元。净利润为3640万美元，摊薄每股收益达1.04美元；两者均高于上年同期。
• 建材分销（BMD）部门销售额增长7%至17亿美元，但该部门EBITDA从6980万美元降至6690万美元。燃料与运输成本上涨以及供应商过渡期的影响压低了利润率。
• 木制品部门销售额（含部门间销售额）增长16%至4.612亿美元。在胶合板价格上涨和工程木制品（EWP）销量增加的推动下，部门EBITDA从1450万美元大幅攀升至4270万美元。
• 管理层预计第四季度BMD部门EBITDA为3500万至4500万美元，木制品部门EBITDA为1000万至2000万美元，反映出季节性因素、单户住宅市场疲软、销量下滑以及成本上升的影响。
• 博伊西卡斯凯德将其2026年资本支出预算下调至1.2亿至1.4亿美元，这主要是由于BMD内生增长项目延迟，而非计划投资的实质性收缩。
• 管理层表示，客户谨慎态度和去库存仍是近期逆风。该公司引用的早期行业预测表明，2027年新屋开工量可能比2026年下降中单位数百分比。

关键财务数据

博伊西卡斯凯德在2026年前九个月支付了2600万美元的定期股息。董事会批准了每股0.23美元的季度股息，将于12月中旬发放。在2026年前10个月，该公司回购了约1.18亿美元的股票，截至10月底授权回购额度还剩约1.2亿美元。

业务与运营表现

BMD部门7%的销售额增长包括大宗商品销售额增长15%、通用产品线销售额增长4%以及EWP销售额增长1%。毛利额增加了360万美元，因为大宗商品利润率改善部分抵消了通用产品线利润率走弱的影响。

销售及分销费用增加了690万美元。该增幅中约80%源于出货运输及燃料成本上涨。管理层表示，团队已将部分出货运费通胀纳入定价中，尽管此类成本比进货运费更难吸收。

过渡至詹姆斯哈迪（James Hardie）作为博伊西卡斯凯德外墙板、复合露台地板、PVC饰板和纤维水泥饰板的独家供应商仍处于早期阶段。管理层表示，哈迪外墙板和饰板销售额实现强劲同比增长，同时该公司继续减少遗留露台地板库存，并铺货TimberTech和AZEK产品。

约80%的遗留露台地板库存已被售出。管理层预计第四季度将代表露台地板的基线销售水平，动力可能在2027年期间逐渐积聚。随着公司优先推广哈迪和TimberTech品牌，剩余的遗留库存可能会延伸至春季露台销售旺季。

在木制品部门，I型工字梁和单板层积材（LVL）的销量同比分别增长10%和18%。这两种产品的实际实现价格同比和环比持平，标志着EWP价格已连续四个季度保持稳定。

胶合板销量从上年同期的3.87亿英尺和2026年第二季度的3.68亿英尺降至3.62亿英尺，反映出更多单板被分配至EWP生产。胶合板平均价格同比增长31%，环比增长8%，达到每千英尺425美元。

管理层将胶合板价格坚挺部分归因于与贸易相关的供应变化。截至2026年第三季度，巴西胶合板进口量同比下降12%，而美国于8月对加拿大单板、胶合板和LVL进口加征了50%的关税。

管理层业绩指引

BMD部门10月份的日均销售节奏比第三季度平均的2610万美元低约10%。管理层表示，由于供应商过渡活动、季节性放缓以及渠道库存处于高位，第四季度日均销售额可能接近2025年第四季度的2200万美元，或略低于该水平。

詹姆斯哈迪协议中包含的财务支持可能会部分抵消收入的暂缓放缓，并在销售放量期间对BMD部门报告的更高毛利率构成支撑。

本季度截至目前的胶合板价格比第三季度平均水平高出约5%。管理层警告称，该季度剩余时间的定价将取决于终端市场需求、季节性以及进口供应的波动性。

由于产量下降以及树脂和定向寻芯板（OSB）腹板成本上升，预计木制品部门的单位制造成本将有所增加。管理层还表明，可能会采取针对性的停产或减产措施，以使供应与需求相匹配。

风险与关注领域

• 第三季度美国新屋开工总量同比下降4%，其中单户住宅开工量下降2%。
• 高企的燃料价格、较高的基准利率以及住房负担能力受限，继续对建筑活动和消费者需求施加压力。
• 客户依然保持谨慎并持续去库存，这加剧了近期的销量压力，同时也提高了对博伊西卡斯凯德“两步法”分销模式的依赖。
• 供应商与分销商的重新调整导致露台地板渠道库存充足，管理层预计这将对第四季度收入构成压力。
• 尽管管理层预计第四季度定价将环比微幅改善，但EWP供应仍大于需求，从而带来了竞争性定价压力。
• 木制品部门多个品类的原材料/投入成本均有所上涨，而开工率降低可能会推高单位加工成本。
• 涉及巴西和加拿大的贸易政策演变可能会继续影响胶合板的供应与定价。

分析师问答环节要点

BMD需求与渠道库存：管理层形容客户非常谨慎，并表示许多客户持有的库存仍高于预期水平。一旦库存恢复正常，博伊西卡斯凯德预计客户将更加依赖“两步法”分销，这种情况可能会持续到2027年夏季及以后。

詹姆斯哈迪过渡期：据管理层称，客户对新产品套件的反应积极，且已实现部分客户转化。然而，公司强调过渡仍处于早期阶段，第四季度将受到遗留露台地板销售极少以及TimberTech产品仍处于销量爬坡期的影响。

EWP定价与生产：管理层表示，价格保护、针对特定市场的调整以及与加拿大关税相关的返利有助于稳定第三季度的实际实现价格。EWP销量在该季度内有所走弱，如果有必要，可能会缩减生产以匹配需求。

开工率：第三季度胶合板开工率约为80%，EWP开工率在80%出头的区间。管理层预计第四季度EWP开工率将下降，因单板被更多转向生产胶合板，且生产工时将做出相应调整。

资本支出延迟：下调2026年预测反映了影响BMD项目的许可、承包商、材料和设备延迟。预计部分支出将推迟至2027年，但管理层将这一变化归因于时间排期问题，而非战略性收缩。

Good day, and welcome to the Boise Cascade's Third Quarter 2026 Earnings Conference Call. [Operator Instructions] I would now like to turn the conference over to Mr. Chris Forrey, Senior Vice President of Finance and Investor Relations. Please go ahead.

Chris Forrey

Good morning, everyone. Welcome to Boise Cascade's Third Quarter 2026 Earnings Call and Business Update. Joining me on today's call are Jeff Strom, our CEO; Kelly Hibbs, our CFO; Joe Barney, Leader of our Building Materials Distribution Operations; and Troy Little, leader of our Wood Products Operations.

Turning to Slide 2. This call will contain forward-looking statements. Please review the warning statements in our press release, on the presentation slides, and in our filings with the SEC regarding the risks associated with these forward-looking statements. Also, please note that the appendix includes reconciliations from our GAAP net income to EBITDA and segment income to segment EBITDA.

I will now turn the call over to Jeff.

Jeff Strom

Thanks, Chris. Good morning, everyone, and thank you for joining us for our earnings call. I'm on Slide 3. In the third quarter, total U.S. housing starts and single-family housing starts decreased 4% and 2%, respectively, compared to the prior year quarter. Our consolidated third quarter sales increased 8% year-over-year to $1.8 billion. Our net income and earnings per share were $36.4 million and $1.04 per share, both higher than the prior year quarter. We are proud of the results our team delivered in the quarter.

The operating environment characterized by rising fuel prices, political uncertainty and cautious consumers facing growing affordability challenges persisted, but our focus and execution did not waver. Our divisions work together to unlock the value of our integrated model, the resilience of which was on full display during the quarter.

Last quarter, we announced that we would partner with James Hardie as our exclusive supplier of siding, composite decking and PVC and fiber cement trim. With the World Series having just wrapped up, it feels only appropriate to reference that announcement as the opening pitch, and we are still in the early innings of operationalizing the agreement with the transition unfolding as expected. Our sales teams have done a tremendous job balancing the duties of selling through legacy inventory by actively developing product knowledge and identifying market opportunities across James Hardie's TimberTech and AZEK product lines.

Our sales of Hardie siding and trim products continue to show strong year-over-year growth. I want to recognize the BMD associates across our footprint for attacking a strategic initiative of this scale. I'm pleased that in less than a full quarter, we were able to meaningfully reduce legacy stocking positions and made great strides with the load-in of new products.

Work remains to rebuild revenue in our general line product category, but we have excellent products and exemplary distribution footprint and the right team in place to seize the opportunity. Kelly will now walk through our segment financial results, capital allocation priorities and fourth quarter guidance, after which I'll provide insights on our business outlook and make closing comments before we open the call for questions. Kelly?

Kelly Hibbs

Thank you, Jeff. I'm on Slide 4. BMD sales in the quarter were $1.7 billion, up 7% from third quarter 2025. Segment EBITDA of $66.9 million in the third quarter compared to segment EBITDA of $69.8 million in the prior year quarter. Gross margins increased $3.6 million compared to the prior year quarter, resulting from higher gross margins on commodity products, offset partially by lower gross margins on general line products. Selling and distribution expenses were up $6.9 million from third quarter 2025, approximately 80% of which was due to higher outbound delivery and fuel costs.

In Wood Products, our sales in the third quarter, including sales to our Distribution segment, were $461.2 million, up 16% compared to third quarter 2025. Segment EBITDA was $42.7 million compared to EBITDA of $14.5 million reported in the year ago quarter. The increase in segment EBITDA was primarily due to higher plywood prices and EWP sales volumes. These increases were offset partially by higher per unit conversion costs.

Moving to Slides 5 and 6. BMD's year-over-year third quarter sales increase of 7% was driven by net sales price and net sales volume increases of 5% and 2%, respectively. By product line, general line sales increased 4%, commodity sales increased 15% and sales of EWP increased 1%. Sequentially, BMD sales decreased 2%, a solid result when considering market dynamics and disruptions from supplier transition activities and a special shout out to our commodity sales team for delivering year-over-year and sequential sales increases.

Our third quarter gross margin was 14.3%, down 80 basis points year-over-year. Gross margins on general line products were negatively influenced by destocking associated with the transition of our composite decking supplier, offset partially by improved gross margins on commodity products. On a sequential basis, supplier transition activities and a lower proportion of general line sales were the primary drivers of our gross margin decline.

BMD's EBITDA margin was 4% for the quarter, down from 4.5% in the year ago quarter. The 50 basis point decline resulted from lower gross margins and higher selling and distribution expenses, offset partially by improved operating expense leverage from higher sales volumes. On a sequential basis, EBITDA margins contracted from the 5% reported in the second quarter. Seasonal demand deceleration, lower gross margins and reduced operating expense leverage from lower volumes impacted our third quarter results.

Turning to Wood Products on Slide 7. Third quarter I-joist and LVL volumes were up 10% and 18%, respectively, on a year-over-year basis. Sequentially, I-joist volumes decreased 4% and LVL volumes increased 2%. As it relates to third quarter pricing, I-joist and LVL realizations were flat year-over-year and sequentially. Our third quarter realizations marked four quarters of price stability in EWP. Price protection mechanisms on contracted volumes, market-specific competitive adjustments and rebates to support volumes sold into Canada that were subject to tariffs held realizations stable despite the price increase announced last quarter.

Turning to Slide 8. Our third quarter plywood sales volumes was 362 million feet compared to 387 million feet in third quarter 2025 and 368 million feet in second quarter 2026. The year-over-year and sequential decreases in plywood volumes were driven by greater utilization of veneer into EWP. Our average plywood net sales price was $425 per thousand in the third quarter, representing a 31% increase year-over-year and an 8% increase sequentially. We attribute the continued improvement in plywood pricing to supply side influences resulting from trade policy decisions regarding Brazil and Canada.

Brazilian plywood imports have declined by 12% year-over-year through the third quarter of 2026, primarily impacting Southern Yellow Pine plywood markets. In August, the United States imposed 50% tariffs on Canadian veneer plywood and LVL imports that impacted Western plywood markets. We anticipate evolving trade policy will continue to influence plywood market dynamics.

I'm now on Slide 9. We had capital expenditures of $90 million in the first 9 months of 2026, including $27 million in the third quarter. BMD and Wood Products spent $8 million and $19 million, respectively, on capital projects in the third quarter. We are reducing our capital spending range for 2026 to $120 million to $140 million, principally a result of project delays on several BMD organic growth projects.

Speaking to shareholder returns, we paid $26 million in regular dividends during the first nine months of 2026, including $8 million in the third quarter. Our Board of Directors recently approved a quarterly dividend on our common stock of $0.23 per share that will be paid in mid-December. Through the first 10 months of 2026, we repurchased approximately $118 million of Boise Cascade common stock, including approximately $9 million between July and October. At the end of October, approximately $120 million of our outstanding common stock was available for repurchase under our existing share repurchase program. The ongoing strength of our balance sheet and cash generation capability through the cycle leaves us well positioned to continue pursuing our strategic growth objectives while taking a steady, disciplined approach to shareholder returns.

I'm now on Slide 10. We have outlined a range of potential EBITDA outcomes along with the key assumptions underlying these projections. We currently estimate BMD's fourth quarter EBITDA will be between $35 million and $45 million. Our daily sales pace in October decelerated from the third quarter sales pace of $26.1 million per day and is expected to moderate further due to seasonal slowing and supplier transitions in the channel. Specific to composite decking, we have made very good progress on wind-down and ramp-up activities, but expect more pronounced revenue declines in Q4 given the level of inventory that has been placed into the channel through recent supplier and distributor realignments. Gross margins are expected to be between 14% and 14.75%. Included in our James Hardie agreement are provisions for financial assistance to support our sales ramp that may partially mask the impact of temporary moderation in BMD's revenue and lead to elevated gross margin percentages throughout the sales ramp.

Turning to our anticipated results for Wood Products. We estimate fourth quarter EBITDA will be between $10 million and $20 million. In addition to typical seasonal factors, our results will reflect continued weakness in single-family housing, elevated fuel and transportation costs, and higher input costs. We expect sequential volumes to decline high-teens to mid-20%. EWP pricing is expected to increase slightly on a sequential basis.

In plywood, we expect volumes to decline mid- to high single digits sequentially. On plywood pricing, quarter-to-date realizations are approximately 5% above our third quarter average, with the balance of the quarter dependent upon end market demand, seasonality and ongoing import supply volatility. We expect our per unit manufacturing costs will increase primarily due to lower volumes and higher resin and OSB webstock costs. Lastly, we anticipate an effective tax rate for the fourth quarter of approximately 5%, influenced by the purchase of tax credits that decrease our rate and the expected lower level of income before tax in the quarter.

I will turn it over to Jeff to share our business outlook and closing remarks.

Jeff Strom

Thank you, Kelly. I'm on Slide 11. High fuel prices and an inflation-driven increase in benchmark interest rates have amplified the affordability challenges that have constrained the new home market throughout 2026. These realities and typical seasonal declines will be headwinds on fourth quarter construction activity. Early industry projections for 2027 indicate that housing starts are expected to decline mid-single digits from 2026 levels.

Our consistent performance relative to the muted broader market conditions in 2026 is a testament to Boise Cascade's national scale and regional expertise. In this environment, customers are hesitant to make significant inventory commitments, increasing the reliance on BMD's in-stock product availability and next-day delivery capabilities.

In Wood Products, our vertically integrated veneer production has insulated us from risks associated with the purchase and importation of veneer. Boise Cascade's integrated operating model strengthens our ability to respond to customer needs and changing market conditions. By coordinating manufacturing, inventory and logistics decisions across our Wood Products and Building Materials Distribution segments, we improved channel visibility and more effectively align supply with end market demand.

Beyond the near-term uncertainties, long-term residential construction fundamentals remain positive, and we believe the investments made throughout the business cycle have us well positioned for the eventual recovery in housing starts. Market dynamics aside, our focus will remain on our customers to deliver the products and services they need to be successful.

Regarding our supplier transition activities in BMD, as we begin climbing the sales ramp with our new suite of products, we know the only way to maintain and grow customer base will depend on consistent execution. We look forward to providing more progress updates as we move into 2027.

Thank you for joining us today and for your continued support and interest in Boise Cascade. We welcome any questions at this time.

Operator

[Operator Instructions] And our first question will come from Susan Maklari with Goldman Sachs.

分析师问答

Susan Maklari

My first question is talking a little bit more on the fourth quarter outlook. You mentioned that in BMD, your daily sales are down about 10% sequentially so far. And when we think about the environment out there and the seasonality as we go into year-end, can you just give us a little more color on how we should think about the moves in the back half of the quarter? And maybe what do we need to see for things to get a little better versus perhaps take a slightly -- another step down?

Jeff Strom

Sue, this is Jeff. I'll start with that a little bit. Just from talking to our customers overall, I would tell you that the word I've used is really, really cautious, and that's obviously having an impact on the demand that we're seeing. And the other thing that we're hearing from them is that they still have a lot of inventory above what they really want. And so they set targets, here's the days we want to have on hand, and then it has moved now since they originally set that. So there's still a little bit of work to go on there.

So what we're hearing, obviously, is there is going to be -- once they get to the position they want a really, really big reliance on 2-step distribution. And I think going forward, the one thing that's a little bit different that we're hearing this time is it's not just, hey, we want to rely on 2-step distribution to get us through the winter. We're hearing loud and clear, it's a lot longer than that and carrying them into the summer and beyond that. So we feel good about that. We think we're set up really, really well to service them whatever comes up.

Susan Maklari

It's good to hear that the 2-step model is continuing to be of real value in this environment. And then maybe with that, can you talk a little more about the progress on the transition within the composite decking and the siding supplier agreements. Just where you are with that, how we should think about the moves there into year-end, and where you'll be positioned as we think about early '27?

Jeff Strom

Yes, absolutely. I would just start with this, particularly on the decking side. It is very early, and I want to state that. As far as the product goes, it is beautiful. It's [indiscernible] compliance. They have the complete PVC line and the fire rating and all those we really believe are an advantage for us. Since we've really started to hit the market a little bit, the customer reception has been great. It's really been exactly what we expected and what we're told. We hear over and over that they want to continue to support us and work with us.

We have seen a few conversions. But again, I'd just stress, it is early. The [ block stores ] national accounts, I think they really see the benefit of this full suite of products once we're fully ramped up and ready to go. We've engaged obviously more and more with the Hardie sales force and they're excellent, and we really believe that they will help, along with our sales force, drive some demand together. But right now, we are. We're working on the winter buy. We're out there after. We're still loading in some of the AZEK. I would tell you, as expected, the Hardie siding growth has been really strong so far, but we have a long way to go, and this is a major undertaking. But we are thrilled about our future together and the direction we're heading, but it will take some time.

Joanna Barney

Yes. Let me just jump in there and echo what Jeff is saying. Our siding sales were up significantly in the third quarter, which we expected, really up more than enough to offset the drawdown on our legacy decking sales in the quarter. We expect that, that siding business is going to just continue to grow. We are seeing a lot of success, to Jeff's point, in driving decking conversions. We are bringing a lot of our customers with us. So we see a lot of -- ton of upside opportunity there. And again, 75% of the decking market still uses traditional wood, right? So the total opportunity that we see in decking is tremendous. So we're excited about that.

That said, I will tell you that fourth quarter is going to be noisy for us. Our legacy decking sales are going to be minimal going forward. We've sold through probably 80% of that now. And our complete strategic focus is turning really to the Hardie TimberTech product categories in the fourth quarter. But we just started selling TimberTech last month, right? So also understand, to Jeff's point, the channel has absorbed a lot of decking over the past couple of months now with multiple distributors changing suppliers. And as all of that has happened, customers are really starting to work to reduce their net working capital, and we're heading into winter. So with that, we'd expect fourth quarter probably becomes our base level of sales on decking, and then we'll start to gain upward momentum as we move into 2027.

Susan Maklari

And then I just want to squeeze one more in, which is: can you talk about conditions in EWP? And especially given the deceleration that a lot of the builders are talking to into year-end and then likely even into early 2027, how are you thinking about pricing there and the competitive environment and how that could come through relative to volumes in that part of the business?

Troy Little

Yes. Thanks, Sue. This is Troy. Yes, I guess, first, on the price side, we held -- the prices held sequentially. That was primarily due to the price protections that we had in place. We are continuing to see the pressure in the market. And in some cases, we've had to adjust relative to our previously announced increase. And then the impact of the Canadian tariffs in the West in terms of some of that veneer coming down out of Canada, maybe we haven't seen the full impact of that yet, but that is there.

So we still believe that we're going to see some slight improvement in Q4, but really because of that pressure continues on price just because there's a lot of supply available above demand, I would hate to speculate. Even on our previous announced in -- going into, say, Q1, but we do still see some activity or some opportunity in price in Q3. But relative to volumes, we entered the Q3 with a very strong profile. The graph on that was straight down through the quarter. We worked our order file, but then we started to see our production exceed demand. We had some opportunity to move into the inventory side, replenish some depleted inventories. And now we've just got to the point now where it is shifting that veneer over to the plywood side.

And so going into Q4, right now, we're expecting volumes on the EWP side to still be challenged. As Jeff just mentioned, we've got key dealers out there still destocking and relying on the 2-step going into the end of the year. And so right now, the way we're looking at it is comparing to, say, Q4 of last year, both on EWP volumes as well as plywood volumes. In Q4 of last year, we did take some market-related downtime, and we're prepared right now to do that if necessary to match supply to demand.

Operator

The next question will come from Michael Roxland with Truist Securities.

Niccolo Piccini

This is Nico Piccini on for Mike. I just wanted to revisit the 4Q BMD guide. Is there a way to think about or maybe dimensionalize the sequential decline through like seasonal demand decline, maybe a real less consumption or true demand decline and then the supplier shakeup, and then any financial support you might be receiving from Hardie?

Kelly Hibbs

Yes, Nico, this is Kelly. Good to hear from you. Yes. So the sales pace so far in the fourth quarter for BMD, we indicated it's about 10% off of the $26.1 million daily sales average that we had in the third quarter. And so if you think about October, November, December, November and December are always going to be weaker in terms of the daily sales pace, just given weather and there's also fewer sales days in those two months compared to October. And so as we've alluded to, there's going to be a number of headwinds for us beyond just the normal seasonality with weather and holidays and those sorts of things.

Joe hit on it in terms of as we work through the supplier transitions, the channel is fairly full in many cases, and we have dealers looking to wind down their inventory as they get positioned for year-end. So I think all those will be headwinds. And I guess to maybe put the last point on it before I'll open it up for anybody else is, if you look at what our daily sales pace was last year's fourth quarter, it was about $22 million a day. And so I think that's probably not an unreasonable metric that we might expect to see in the fourth quarter, but maybe even a little softer just given the uniqueness of the supplier transition activity.

Niccolo Piccini

Following your announcement, we obviously saw a lot of other suppliers shake up. I wonder if that was expected or just in general, since you announced this deal, what has or hasn't proceeded with your expectations?

Jeff Strom

I think everything has proceeded pretty much exactly as we thought. We knew that there would be a drag on sales as we transitioned. This quarter, in particular, we'll feel it as we just got product in, and we're still moving some product off. So it has happened really like we thought it would. And the positive side to that is we heard from a lot of customers across the country that they would be there to support us and to help us or to work with us, and we're seeing that as well. So I don't think there's really been any large surprises there at all.

Niccolo Piccini

And then just maybe one final one. You mentioned the lower CapEx guidance was on project delays and distribution. Can you give a little more color on that? What drove that? Is that intentional or not?

Kelly Hibbs

Yes, sure. So we did reduce the range for 2026, Nico, and that was largely just a function of some organic growth projects we had going in BMD that were frankly delayed, whether it's permitting, whether it's getting contractors lined up, whether it's materials, equipment, et cetera. It's really just a function of delays as opposed to a meaningful pullback. And lastly, I would say, in terms of 2027 CapEx, we haven't -- we're not at the point yet where we're prepared to speak to the range. But there will be some of the '26 that we will push over into 2027, but we've still got to have a broader conversation internally in terms of what our base level of 2027 spending will be. So we'll get back to you the next time we talk around the 2027 range.

Operator

The next question will come from Ketan Mamtora with BMO Capital Markets.

Roshni Athaide

This is Roshni Athaide for Ketan. I was just wondering if you could maybe talk a little bit more about your Wood Products guide and walk us through the bridge. If plywood is maybe like a $20 million per year-over-year tailwind, like what are the other offsets we should be thinking about there?

Troy Little

Yes. This is Troy again. Yes, I guess I'd just reemphasize that at least the way I'm looking at it is, going into Q4 of last year, and so I'm making that comparison. Our prices are similar in terms of EWP. So it's not EWP price. Like you mentioned, plywood prices are up. But really, for the -- as it relates to the fourth quarter forecast, it's a volume issue and volume relative to some escalated cost, that's really impacting our conversion cost number or manufacturing cost number.

And so like I mentioned, our volumes for EWP have come off. We've shifted over to plywood and then the next shift is to curtail and match the demand. And so in fourth quarter of last year, we did have that around the holidays. We're anticipating some of that. We also have some maintenance-related downtime in some of our mills. And so that volume is really the driver.

And then on the cost side, we've seen cost -- I just looked at like, say, 10 key input drivers for us, and our costs are up anywhere from 5% to 30%. And of the 10 that I looked at, on average, were up about 10%. So increased costs, lower volumes, that's what's really driving that forecast.

Roshni Athaide

Okay. Are you able to also just quantify like the transportation or freight headwinds that you had in Q3? And how much of that is embedded going from Q3 to Q4?

Kelly Hibbs

Yes. So what we did speak to, Roshni, in terms of transportation was specific on the distribution side in terms of quantifying the selling and distribution expenses and how much of that related to fuel and delivery costs, which was about 80% of our selling and distribution increase in BMD. As we think forward fourth quarter, no reason for us, I guess, to believe that diesel fuel and other things will come off at this point. The only, I guess, sequential benefit we could see there is just the fact that we expect to have lower volume, so lower outbound actual volume. Anything else we'd add on freight and transportation, guys?

Jeff Strom

No, I would say, the inbound freight, obviously, we can absorb very easily. The outbound freight is a little bit more challenging. But I would give a shout out to the BMD team, has done a fantastic job of building it into the pricing and really done a nice job of covering where we can.

Roshni Athaide

And just one more for me. I think you mentioned that you've sold about 80% of your old supplier products so far. Do you expect to finish the rest through Q4? Or is there going to be like spillover into Q1?

Jeff Strom

No, I think given what's in the channel right now and how full it is with all the switches that have taken place, we're pretty comfortable with the 20% we have left. And yes, we will continue to sell some of it if the right opportunity comes along. But decking season is around the corner in the spring, and we just believe that we'll have more success selling it then. And so we'll move what we can, but the plan is when decking season kicks in, we'll move the rest of it.

Joanna Barney

Yes. And with the early-buy decking opportunity, we really want to make our strategic focus the Hardie TimberTech brands. And so we're intentionally making -- shifting away from that right now in order to put our full strategic focus on the future and the brands that we're going to be partnered with in the future.

Operator

Our next question will come from Nicholas Sherwood with Bank of America.

Nicholas Sherwood

This is Nick Sherwood speaking for George Staphos. Can you talk about some of your operating rate assumptions when thinking about pricing and just how you're going to be managing operating rates through the year and into 2027?

Troy Little

Yes. I'd say right now, relative to Q3, like I mentioned, we were able to run fairly -- if you're looking at the dry veneer side and then whether that dry veneer goes to EWP or to plywood, we ran fairly well through the quarter. Our operating rates through the quarter were 80% range for the plywood side and low 80s for the EWP side. That's where I'd expect going into Q4. We're going to be shifting away more veneer away from EWP. So those operating rates will come off. And then plywood, while we're running, we're going to run fine. It's just a matter of the hours that will be taken out if that comes to pass.

Nicholas Sherwood

And then for my second question, can you just talk about the James Hardie transition? And what kind of operational milestones should we think about for that partnership in 2027?

Joanna Barney

I think the way that we look at the James Hardie TimberTech, where we're trying to go, our objective there was never just about replacing our existing sales, right? We've really partnered with James Hardie and TimberTech brand in order to go out and gain share, expand our overall market position, take over the marketplace. So the opportunity isn't just selling decking and siding products for us. We really see an opportunity to go drive the entire market toward adopting an exterior solution. We measure our success by our customers' success, by our customers' growth. So if we can bring them the right solution, if we are aligned with the right suppliers who are long-term market winners, then our customers will begin to grow and that becomes a sustainable model for us. So that is always our focus.

And so we partner with the best-in-class brands in order to do that. The suppliers who are the most innovative, the ones that bring solution-based opportunities to our customers and to the market, and then the rest of it is just based on our execution. And we are really extremely confident in our ability to go execute.

The next question is a follow-up from Ketan Mamtora with BMO Capital Markets.

Roshni Athaide

This is Roshni filling in for Ketan. Just one more question. Could you please provide some perspective on channel inventories in siding, particularly whether they're at normalized levels? And then also on siding growth, could you just break down how much is coming from market versus incremental share gains? Just any perspective there would be helpful.

Jeff Strom

Yes, I'll start with that and then Joe can fill in. I think the same thing has happened with siding is what happened with decking. When there's a switch, people started trying to move the material into the market. However, I will say we are seeing some gains on our Hardie siding. We are. They're meaningful. We believe we're picking up share. We don't think that the market is so strong as much as it is that we're gaining share, and we're seeing and feel really good about that and think about our opportunity going forward. I really believe in this quarter that the gains we will pick up on siding will really help to cover what we won't get on the decking side as we transition.

Joanna Barney

Yes, I would agree with Jeff. Our siding sales have picked up significantly. We believe they're going to continue to pick up. We're picking up a lot of that business from the James Hardie exits that they've made in different markets as far as other distributors. So we picked that up. And yet, there was still quite a bit of siding inventory in the market from those exits. So we anticipate that, that's just going to continue to grow as those other distributors wind down and we ramp up.
