Thank you, Binit and good morning everyone. I appreciate everyone taking the time to join our call today. I would like to share with you an update on our 2018 financial highlights and strategic achievements. Then I will turn the call over to Peter who will discuss our Q4 financial results in more detail. I will then finish with an update on our strategic priorities and outlook. Starting on Slide 2, we completed a year of very strong financial performance and achieved key milestones of value creation despite a moderating growth environment and a volatile commodity market. In 2018, we again showed the agility and resilience of our exceptional team, platform and strategy. Net sales in 2018 grew by almost 10% and EBITDA grew by almost 20% to a record annual $502 million, earnings per share increased by nearly 50%, value-added sales grew by an impressive 10% as we continued to invest in our strategic growth capacity. Our dedicated team accomplished these results while at the same time executing on our working capital initiatives generating a record $186 million in free cash flow for the full year 2018. Using that strong cash flow generation, we achieved our leverage target announced at the time of the transformative ProBuild acquisition in 2015. Turning to Slide 3, I would like to spend a few minutes highlighting a few of our strategic achievements in 2018. First, we continue to realize the growth and margin expansion benefits of our strategic investments and value-added products capacity by helping our customers solve challenges like increasing cost, lack of labor, and waste management. These investments are driving higher margin sales as we continue to grow our industry-leading manufacturing network through new plants, automation, new machinery, and system upgrades. Since 2016, we have opened eight state-of-the-art truss and millwork manufacturing facilities. As these facilities mature, sales will continue to grow, enabling us to capture share of the expanding offsite fabrication market as homebuilders look for solutions to overcome their labor and cost challenges. We also continued to make progress on our operational excellence initiatives. These best practices are being implemented throughout the organization to make Builders FirstSource more agile and more responsive. Initiatives underway include enhanced business analytics, pricing management tools, our My BFS Builder Customer Portal, and digital safety among others. I will specifically highlight our delivery optimization success a little later in the call which is already posting tangible benefits furthering the competitive advantage of our efficient distribution network. We once again delivered on our commitment to generate strong free cash flow to fund our long-term investments, while restoring balance sheet financial flexibility. We funded $101 million in capital investments including further expansion of our industry-leading value-added production capacity refreshing our fleet of rolling stock and upgrading our asset base. At the same time, we reduced our leverage to 3.1 times as of December 31st, 2018 a reduction of 1.1 times compared to the prior year end. Lastly hiring, training, and retaining the best people continues to be a top priority. We invested in the addition of 160 new sales team members in 2018. We also introduced training tools and processes to systematically drive and enable the productivity of our high-caliber sales culture throughout the organization. We are only strong as our 15,000 talented team members and we remain committed to growing and developing future leaders throughout the organization. I will now turn the call over to Peter who will review the fourth quarter financial results in more detail.

Thanks Chad. Good morning everyone. As a reminder, we have included adjusted figures to normalize for one-time integration and other costs. Please also note that we had one more day of sales in the fourth quarter of 2018 than the prior year. So, I will speak to our results on a sales per day basis. We reported net sales of $1.8 billion, a 0.5% increase compared to the fourth quarter of 2017 including commodity deflation of 2.8% and an estimated 3.3% from sales unit volume growth. Our value-add products increased 6.8%, led by a particularly notable 9.1% growth in manufactured products. Gross margin was $492.8 million in the fourth quarter of 2018, increasing by $61.6 million or 14.3% over the prior year. We recorded our highest quarterly gross margin percentage ever at 27.1%, up approximately 290 basis points from the fourth quarter of 2017. And a sequential improvement of 240 basis points compared to the third quarter of 2018. Commodity prices declined sharply again in the fourth quarter of 2018, continuing the fall that began in June. Framing lumber and sheet goods prices declined 39% and 32% respectively compared to the beginning of the third quarter. As a result, our gross margin percentage improved as cost declined relative to our customer pricing agreements. Our team again demonstrated its ability to manage through commodity price volatility. And at the same time maintain a consistent focus on delivering high-quality value-added solutions to our customers. As we have discussed on prior calls, commodity inflation causes short-term gross margin percentage compression when prices rapidly rise. And margin percentage expansion when prices rapidly decline relative to the short-term pricing commitments, we provide to our customers. Our SG&A as a percentage of sales increased by 160 basis points on a year-over-year basis. This increase was primarily due to increased commissions and incentives related to our particularly strong and highly profitable growth in the fourth quarter. We pay higher incentives for higher-margin sales. And accordingly our outsized gross margins led to higher commissions expenditures in the quarter. Adjusted interest expense for the quarter was $26.6 million compared to $33.2 million in the prior year, a decline of $6.6 million. The reduction was largely as the result of refinancing transactions the company executed in 2017 as part of the disciplined capital management plan. As well as our ongoing debt reduction, slightly offset by a rising interest rate environment. Adjusted net income for the quarter was $53.1 million or $0.46 per diluted share compared to $46.6 million or $0.40 per diluted share in the fourth quarter of 2017. The year-over-year increase of $6.5 million or 14% was primarily driven by improved operating results, combined with lower interest expense. Fourth quarter EBITDA grew by $28.1 million or 29% to $125 million. The year-over-year improvement was largely driven by our strong sales growth, particularly in the value-added product categories and expanded gross margins from commodity price deflation. As mentioned, the outsized benefit to gross margin from the rapid deflation will diminish over time as commodity prices stabilized and gross margin percentages return to a more normalized level. Turning to slide 6. Our ongoing strategy to invest in manufacturing capacity once again delivered results in the fourth quarter. We grew the value-added products by more than double the market rate. Our unrivaled platform provides us significant ongoing opportunities to increase both our overall market share and the penetration of higher-margin products. In addition, we are committed to continuing the expansion of our current network of 58 manufacturing facilities strategically located across the country. Given the ongoing challenges faced by our customers, the demand for our labor-saving products continues to grow and provides us with expanding opportunities for profitable growth. Our 2019 plans to expand our manufacturing and value-added capacity includes new truss and millwork plants, new truss lines in existing plants, new door machines, new machinery and new systems impacting dozens of markets and locations. In total, we expect to invest nearly one-fourth of our total 2019 capital expenditures in our value-add growth initiatives. Turning to page 7, our fourth quarter sales unit volume per day grew an estimated 4.5% in the single family new construction end market, outgrowing single family starts growth. Our sales volume to R&R and other end market grew by 1.1%, somewhat muted by the slowdown in the Midwest where much of the economy is driven by the Ag industry which is being impacted by the trade dispute with China. Multi-family declined about 1.8% as expected. Turning to page 8, total liquidity as of December 31, 2018 was an ample $595.5 million consisting of net borrowing availability under our revolving credit facility and cash on hand. Capitalizing on market opportunities and our financial flexibility, we executed a series of open market purchases of our 2024 notes, totaling $53.6 million in the fourth quarter of 2018. In February of 2019, we repurchased an additional $20.4 million in aggregate principal amount of the same 2024 notes. Our net debt-to-EBITDA ratio as of December 31, 2018 was approximately half of what it was at the end of 2015 only three years ago after our strategic acquisition of ProBuild. This is an important milestone for us and we are proud of the exceptional work our team has done to integrate a transformative acquisition, execute to deliver the synergy targets and ultimately deliver on the promise to delever the balance sheet. Moving to slide 9. Our cash generation was driven -- was again driven by strong EBITDA growth. And our teams focus on working capital conversion execution in the fourth quarter. The $186 million of free cash flow generated for the full year, represents an all-time record for our company after funding for $101 million in capital investments. Our current assets are covering an increasingly larger portion of funded debts, reflecting our steadily improving financial stability. As we look forward to 2019, we have a high level of confidence in our team's ability to execute on the initiatives within our control. Let me provide some color on what we see for our first quarter of 2019. We'll have one less selling day in the first quarter of 2019 versus the prior year. So our guidance will be provided on a sales per day basis. We expect commodity price inflation to negatively impact our sales in the range of 6% to 8% in the first quarter. As a result despite expected increases in unit volume, we expect our first quarter sales per day to be down by a low single-digit percentage as compared to the first quarter of 2018. We expect gross margin percentages to be down sequentially from the fourth quarter of 2018 as a portion of the benefit derived from the rapidly declining commodity costs begins to recede. However as compared to the gross margin percentage in the first quarter of 2018, we expect an improvement in the range of 180 to 200 basis points. As a result, we expect first quarter EBITDA to grow at a mid-to-high single-digit percentage as compared to the first quarter of 2018. As we have begun 2019, the macroeconomic environment and fundamental demand factors all remain supportive of growth in single family starts in the housing market generally. However, recognizing the uncertainty in the new housing market and the highly volatile commodity prices, we will at this point refrain from providing detailed full year guidance. We remain confident in the industry and in our self-driven performance. We expect our operational excellence initiatives to contribute between $14 million and $16 million in our 2019 EBITDA. We will continue to invest in our business through capital expenditures at approximately 1.5% of sales. Regarding cash taxes, we expect to fully utilize our NOL tax asset and become a federal cash taxpayer again in the second half of the year. We expect an effective tax rate of approximately 25% for the full year. Cash interest and interest expense are both expected to be in the range of $95 million to $100 million in 2019. As we continue our systems integration work to support our operational initiatives, we expect onetime related cost of about $15 million to $20 million for the year. As a result we expect to generate $180 million to $210 million in free cash flow for the full year of 2019. I will now turn the call back over to Chad to provide an update regarding our strategic priorities and outlook.

Thank you, Peter. Moving to slide 11, although the housing market in starts growth have moderated over the last few quarters, we remain confident in the fundamental underpinning of homebuilder demand and expect that single-family housing starts will continue to move towards the $1.1 million historical average over the next several years. As mentioned, we continue to develop our sales force and invest further in our manufacturing and value-added facility expansion initiatives. These growth platforms provide us significant ongoing opportunities to increase our market share and increase the penetration of our higher-margin products. In addition to capturing market growth, the growth in our value-added product sales and our operational excellence initiatives underway are expected to generate an additional $100 million of profitability in the coming years. Our plan remains intact to generate EBITDA approximately 50% higher than our 2018 full year figure of $502 million or roughly $750 million as we reach historic norms. We have revised our cash flow targets to better reflect the cash culture we are building. Our expectation is that over time we will achieve greater than 85% conversion of our adjusted net income to free cash flow. The cash generated will be used to fund strategic growth investments and to further improve our financial flexibility. Turning to slide 12. We detail our specific growth initiatives expected relative to the 2018 performance. Our core business strengths including our national footprint unmatched scale in manufacturing capability and exceptional sales force provides us with a platform well positioned to capitalize on the continuing opportunities, we see for core growth in the residential housing market. We expect to generate an incremental $130 million to $160 million in EBITDA compared to 2018 as housing starts to normalize. In addition to this core growth, we will continue to expand our national manufacturing footprint and capabilities to grow our higher-margin value-added products faster than the overall market. Our plans currently call for investing in approximately 20 new facilities by expanding our nationwide footprint to serve a number of locations where we see great opportunities to serve market needs with our customers. Our plan includes a set of operational excellence efficiency initiatives underway including investment such as distribution and logistics software which I will discuss in more detail on the next slide. As well as pricing and margin management tools, back office process efficiencies and information system enhancements that are expected to contribute between $65 million and $75 million in incremental annual EBITDA. These projects when rolled out across our 400 locations are designed to deliver significant cost benefits and margin expansion opportunities. They will further differentiate our service levels, strengthen our connectivity with our customers and provide economic and strategic value that is unrivaled by our smaller competitors. These initiatives are well defined and well within our control. We remain confident that when scaled they will generate the returns we have targeted. Moving to slide 13. Our dispatch and delivery optimization initiatives have now been rolled out to approximately 140 locations. The goal is to systematically drive best-in-class operational efficiency and customer service. Logistics optimization include the use of GPS technology to allow for predictive maintenance, driver performance monitoring, route optimization, centralized dispatch and more precise management of vehicle disposition and procurement. We have already seen an improvement in driver productivity, fuel cost and safety. Sales and operational alignment centers around what we call the electronic delivery board. The enhanced reporting has reduced paperwork and allowed our sales team to easily understand the status of all orders improving accuracy and efficiency. For example, we have seen a reduction in delivery expense and improvement in sales per FTE where fully adopted. The customer collaboration tools provide the delivery status and job site photos to be automatically uploaded to our online portal My BFS Builder so that sales dispatch and the customers can collaborate online. This is already shown to improve construction times to reduce hotshots and product returns and has also improved customer satisfaction. By the end of 2019, we expect to roll the system out to over 250 locations to make up more than 75% of our sales. In 2018, we delivered profitability and on that a long standing strategic priority to restore financial flexibility marking the completion of our successful integration of ProBuild. At the same time, we continue to invest in building a more durable, value-added solutions platform that has demonstrated growth despite a moderating end-market environment. The ongoing roll out of our operational excellence initiatives also continued creating an even more agile and responsive Builders FirstSource. Despite the commodity price volatility, we demonstrated the strength and value of our differentiated platform across our national footprint to produce solid growth. While the economy and key fundamental demand factors remain supportive of housing growth going forward visibility into 2019 at present is challenging. The timing and extent of the growth in single-family housing starts in our opinion will depend on the continued low unemployment, stable interest rates and homebuilders adjusting to be evolving profile and needs of the home buyers. However, regardless of the exact trajectory of the market, our experienced leadership team and 15,000 dedicated team members remain committed to successfully navigate the changing market conditions. We are better positioned than ever to grow a long-term value for our customers and shareholders and I look forward to building our success together. I'll now turn the call over to the operator for Q&A. Operator, we can now open the call up for Q&A.

Thank you, sir. [Operator Instructions] And going first to Matt Bouley at Barclays.

Good morning. Thank you for taking my questions. Congrats on the quarter and on reaching your leverage targets as well.

Thank you.

So I guess on that point with leverage down near three times you authorized the repurchase of course. What can you say about the M&A pipeline in this environment? And relative to share repurchase, should M&A be a larger priority this year? Or do you anticipate kind of further deleveraging as you get towards the lower end of your leverage range there before M&A becomes a bigger tool? Thank you.

Yes, I think it will be a little of both. I -- we want to continue to delever. As I've mentioned in the opening remarks, we certainly want to expand our value-added platform. And so if some opportunities came along there to do so -- to buy those greenfield, we would certainly look at it. At the present time, I don't anticipate any significant M&A. But certainly, we would consider some smaller M&A options from a value-add standpoint as opposed to greenfielding. Greenfielding is just getting harder and harder these days with all the restrictions and permitting requirements. And it's just taking longer and longer to get buildings out of the ground. So I would certainly be open to some smaller M&A activity and at the same time continue to delever a bit.

Okay. I appreciate that. And then secondly, just around the guidance. I think the first quarter EBITDA guide given the gross margin performance, it would suggest there's still some offset I guess on the SG&A side. Is that just further commissions and incentives as in Q4? Or is this kind of further heavy lifting around some of your investments? Really just how should we think about SG&A I guess beyond the first quarter? And when some of these investments may kind of reach scale? Thank you.

Yes. So the discussion around SG&A obviously you saw the jump in the percentage. There's couple of factors obviously as we deflate there'll be some natural inflation. Just like we saw the benefit in the earlier months in 2018. But we did see commissions go up. And hopefully that was a clear explanation and that we are -- our commission plans are built to reward our salespeople for selling at higher margins. And so that award is showing both in the fourth quarter and of course a bit in the first quarter as well. The other major factors I would describe comp and benes is certainly an area where we've seen pressure over the last year unemployment is down. And we certainly had to work to take care of our employees and make sure that we have good retention. And we have seen some headwinds in the areas of insurance, both medical and casualty due to ever increasing. It seems medical costs in this country as well as some of the hurricanes and the weather that we've seen. So some areas there where we have -- and we'll likely continue to see some challenges with inflation. But the team is doing a good job of managing expenses and staying discipline particularly in the controllable areas. In our benefits associated with the improvements of the operational excellence are certainly going to be felt throughout the year. And we anticipate increasing over time. It is important to remember seasonality though, right? So Q1 and Q4 are certainly our lowest volume periods. And that's when it will show the highest percentage of SG&A in any given year.

All right. I appreciate all of the detail. Thank you.

We'll go next to Nishu Sood at Deutsche Bank.

Thank you. So the sales per day guidance implies -- for 1Q 2019 implies that you're expecting -- once you factor out the lumber price. So in the commodity inflation drag about mid single-digits gains year-over-year and sales per day. That's obviously a pretty strong performance in light of some of the volatility that we've seen in the housing market. Some builders are reporting double-digit order declines et cetera. So is the -- has the book of business, has it seen any effects from that for you folks? And if so, when would you expect to see it? Your macro commentary sounded still positive, but just wanted to see if you could reconcile for us the pretty robust expectation for 1Q 2019 versus some of the other data points we're hearing from some of the public builders?

Yeah. So I guess I'll start and of course Chad can jump in. The components there in - I would say our expectation is more in the low-single digits increase particularly for single family. There is growth in the business. We've got, of course, a little bit of share that we think we've got a line of sight too. Perhaps a little bit of rounding in some of the number that you're doing the math on. But we think it's in the low single digit range. Reason for our confidence in that is really the performance we had in the fourth quarter for starters as well as the ongoing contact we have with our customers. The sentiment out there despite the headlines and we read them too. But the sentiment amongst the people on the ground is that a lot of what has concerned folks and has slowed people down has begun to abate. Interest rates have dropped a bit, the cost of lumber clearly has dropped a bit. And we think those encouraged homebuyers to get back in the game as things settle down a bit. The pause that we expected we think is just that pause and things will get back to a more normalized level or perhaps slower growth than we've seen in certain points in the past couple of years, still growth. So a lot of optimism out there and despite some lumpiness whether it be weather or a pause we saw a lot of confidence in the underlying demand.

Got it, got it, okay. And second question. On the increased sales commissions you had a fantastic record gross margin as you mentioned 27.1%. Let's suppose that the 25% is the normalized, and I should -- I love your thoughts on that whether that's still the case. So 210 basis points above "normalized" how much incremental sales commission did that drive in basis points?

Let's see. So I guess the first comment I'll make is regarding normal. I still think that 25% is a reasonable proxy for normal in terms of gross margin. We've talked about that in the past. I think that's still true. When we talk about comp and benefits, I don't know that I have a breakdown of the commissions as a percentage. I can tell you it's about half -- a little less than half of the SG&A variance for the fourth quarter. So it's substantial amount…

Got it, got it. And as the -- as we think about this commission I mean it -- was it larger because of the extreme volatility? So the incremental sales commission against where prices were -- I mean I used the benchmark of that 25% normalized gross margin. But does the commission work that way? Or is it against improvement in gross margin so that the extreme volatility might have had a greater effect and pushed those sales commissions on stronger margins up more than they might've been on a normal volatility environment?

Yeah. I think it's fair to say your assumption is right. If you think about it from a purely simplistic level if we are making 20 points normally on some lumber and the underlying cost falls and we talked about it being in the 30% range, it's a substantial increase in the profitability of that particular sale. Just like it -- when we see inflation, the profitability goes south, we both reward and penalize our sales people for achieving higher profitability and lower profitability, respectively. So that net compounding effect of improved gross margins generates a higher payout, because the dollars have increased. And there's a premium associated with higher than normal and in this case much higher than normal margin recovery. Does that make more sense? Is that clear?

No, that's great. Thanks very much.

And our next question is from Trey Morrish at Evercore ISI.

Thanks very much guys. And really good quarter. I want to talk a second about the margin trajectory outside of lumber. So we understand that lumber can have quite a bit of volatility just given the massive pull down. But could you give us some thoughts some insights on what your gross margins outside of the lumber category looks like? Were they also up as well? Or were they kind of more flattish?

They were pretty flat. The only exception to that is where we've done work around our pricing optimization tools. We think that by managing and being a bit more disciplined in some of the tools we have we were able to drive for the year probably about $4 million worth of benefits in those initiatives and a lot of that was in the fourth quarter.

And I'll just add we did see some improvement in the manufacturing products category. As you know, we continue to invest in our truss plants and automate where we need to and we're seeing some efficiencies there. So Peter's right obviously lumber was up, especially the back half of the year, the other product categories were relatively flat, but we also saw a decent little bump in manufactured products.

Okay. Got it. Thanks for that. And then turning back to the volume outlook that you're looking for 1Q. You said it was kind of low single-digit range. But this point we're two-thirds of the way time-wise through the quarter, maybe not quite business and sales-wise. But would it be fair to extrapolate from your comments that you're probably tracking flat to probably up so far year-to-date?

I don't plan to change my guidance and I think we'll make the guidance for the quarter.

Okay. All right.

If that is implied, right. I mean, yes. Thank you.

Thanks.

We'll go next to Mike Dahl at RBC Capital Markets.

Good morning. Mike Eisen on the line for RBC. Just wanted to start off on the value-add products you guys continue to invest and then drive growth here. But we did see it step down a little in the fourth quarter. Can you talk about what drove some of that? And whether you think that's broader market slowdown? Or if we should expect a more consistent mid to high single-digit rates? Or if you guys can reaccelerate that and continue to grow outside in that -- in those segments?

Yes. It's a fair question. There's certainly a deceleration in the growth when you look at the numbers on a consolidated basis, right? I'd say some markets are still very healthy, some markets have weakened on balance, it's a bit slower. There's still a lot of demand for the value-added product, right? There's – despite, again, all of the terrible headlines the demand hasn't really gone anywhere it's still there. And so the availability of labor the job sites being -- not having sufficient people on the ground are all still challenges for our customers. We still are seeing significant year-over-year increase in people investigating, expanding their use of prefabricated products. Whether it be trusses or panels or the better framing system. We are seeing that and enjoying the benefits of that. Gauging it on a quarter-by-quarter basis in terms of growth trying to align it with the overall market growth, it's a challenging thing to do from a forecast perspective. Probably fair that it would step back a bit from its heavier days last year when the overall market was growing at a high rate, but we still anticipate healthy growth through 2019.

Some of it could be regional too. A lot of the heavier used regions of the country over the Pacific Northwest and the Northeast and those tend to be impacted a little more about weather then say Texas would -- isn't impacted as much, but also is as much of a truss market.

Got it. That's really helpful information. And then transitioning to your delivery optimization program. You guys laid out some early successes you've had and desired to roll this out to 75% of the branches before the end of the year. Can you help us think from a P&L perspective some of the early results you've seen in the branches where it is? Whether it'd be better SG&A better throughput? Something that we can help quantify the magnitude of the potential here?

Yes, sure. So we are looking that number for 2018. Still early days in a lot of locations, but really positive feedback from the users and those that have really adopted it and started to see squeeze some juice out of it have seen some really nice benefits on the bottom line. As you can imagine, it impacts both gross margin in the variable cost as well as SG&A in some of the overhead costs. We think that we saw -- and we from our analysis, we've seen about $2 million worth of benefit in 2018 from the delivery optimization tools, which is primarily the software that we manage as well as some other ancillary tools that we're using. We think that of course is going to grow as we get those locations implemented and then ramped up, sort of a two-phased approach for each location.

And I'll just add. In total we see it as a company over the next several years is somewhere around $20 million to $25 million opportunity, which translated -- it means we need to be about 5% more efficient from a delivery standpoint and from a yard personnel standpoint. Or say it in another way somewhere around 30% basis points as a percentage of sales. So it's a real opportunity and I feel very good about being able to achieve those numbers in the coming years.

Got it. Thanks, good luck.

Thank you.

And we'll go next to Jay McCanless at Wedbush.

Thank you. Good morning everyone. So my first question if lumber prices stay where they are in now, theoretically should we expect some deleveraging on the overhead margin just assume we stay like in this 350, 400 band for the full year?

Of course. Yes I mean it's -- we think it's going to work on an adverse way as last year. The growth in commodities benefited us on SG&A as a percentage of sales when it was inflating. And as it deflates, it will go the opposite direction. We didn't add people for example when it inflated so we won't take people out when it deflates. But underlying that I think we're very pleased with the fourth quarter results. There were some skepticism if you recall Jay in the market about whether or not we'll be able to protect our margins in case of deflation, and whether or not we would see the outsize benefit in our gross margin percentages that we claimed. And I think our results certainly proved that we did what we said we would do. And so we'll manage through this year. There'll be some continued volatility commodities always manage to throw us a curveball or two. But I think we're very well positioned. We've proven our discipline and our ability to manage in both up and markets. And we're going to do that this year and focus on the operational stuff that we know we can control. And we'll focus on making money on commodities and keeping the business in line and being disciplined.

Yes. And I'll just add. I don't think I'm going out on a limb to say, its very likely commodity prices will not be as volatile this year as they were last year. I do think, as we get into the spring and summer building season, we will see some inflation. But even, that being said, it's likely going to be a bit of a headwind this year. But all in all, as you guys -- everyone knows on this call, we operate in a cyclical business. And this is just part of it. And in a cyclical business, you have good years, you have bad years. 2018 was a good year and despite maybe some additional headwinds in 2019, 2019 is going to be a good year. So as Peter said, we will deal with what comes our way. But we feel really good about things as we sit here today.

The second question I have with the excitingly bad weather we've in a lot of different locations this year. I'm assuming that the guidance you've given on sales per day includes whatever weather benefit you've seen so far? Could you talk about that a little bit? What impact it's had on R&R? And then also the other one I want to sneak in on the -- could you repeat, and I missed this, so I apologize. But just how much of the 2024 notes you guys bought in, both in 4Q and then this quarter?

Yes. So to answer the second question first. It's about 75 total, 50 in Q4 -- 50-ish in Q4 and 25-ish in Q1. Yes. I mean, I'll make a couple of comments on the weather. I mean, first of all, definitely not a benefit. I'm assuming you were being facetious on that one. A lot of destructive weather, a little bit in the fourth quarter, more in the first. We -- candidly, we don't like getting into the weather reports, but you having heard other folks talk about it, it absolutely is real. Polar vortexes, blizzards, unusual snow in the Pacific Northwest, unusual rain in the Pacific Southwest. So it is certainly an interesting time. Yes, we've included the bulk of what we've seen so far. But I can't say tomorrow's weather pattern is focused in. We'll, have to respond to that, but we think it's pretty well baked in. Certainly, a lot of West Coast disruption, upper Midwest disruption. It's been problematic. But it is what it is.

Sounds good. Thanks guys.

Thanks, Jay.

And we'll go next to Matt McCall at Seaport Global Securities.

Thank you. Good morning, everybody.

Hi, Matt.

Good morning, Matt.

So the -- that you talked about the bogey, 85% average annual free cash flow as a percent of adjusted net income. Can you talk about that? How that looks in 2019? I'm specifically thinking about the impact of lumber on working capital, I mean, how do we think about 2019 relative to that 85%?

Yes. So it's a good question. I mean, part of the reason for not giving guidance is because, depending on where commodities goes there goes my both EBITDA and there goes my working capital, likely in different directions. Same is true with single family starts. The rational for the change is, people got hung up candidly on that long-range plan presentation with regard to the accumulative cash flow and kept trying to lock back to -- so what year and what year. And our point in that is, really to emphasize a normal housing market has a significant tailwind from where we are today on our results. And over time, our performance -- improving performance really thinks back very well to that sort of 85%. Some use more, some use a bit less, but running in that 85% range historically and going forward for cash generation that we can utilize, right, to grow the business to pay down debt, continue to strengthen our balance sheet. So we felt that was a more appropriate way of talking about it, rather than a single dollar amount over a cumulative number of years. So that was a rational for the change. As we get into a full year guide, we can add that sort of list to providing to everybody that percentage for the year.

Okay that's fair. I understand the uncertainty around what lumber does. So I think in the past you talked about 9% to 10% working capital, 9% to 10% in incremental sales. If lumber stays where we are today, how should we think about the full year? Is that still a good rule of thumb?

I would say, generally it is. But you have to account for the lumber volatility as of -- as an impact as well, right? And if you can tell me what my volume is and what commodities we'll do? I can tell you what my working capital impact is going to be.

Okay. I'll work on that. So, Chad, you said you're still going to focus on debt reduction. You've kind of gotten, I think, to the midpoint of the targeted range, if I remember correctly. What's -- do you have a new target established? Or you just continue to work it down in the absence of an opportunity from here? Where -- how do we think about your net debt-to-EBITDA bogey?

Yes. It depends, right? It depends on how we're feeling about the cycle and where we are. It depends about -- it depends on what opportunities may present themselves. I'm not going to turn a blind eye to opportunities, if they come along. If something came along and it required us to pop back up to 3.5 or 3.8 times. But we had a clear runway of bringing it back down in short order. I'm not going to say no to -- or at least, not going to say, I'm not going to look at something like that. We back in 2015, we had no idea ProBuild would come along. And I'm being glad we did it. So it really just depends on the opportunities that are out there. But I would say, bar any significant opportunities that we want to look at. Yes, I'd say, driving it down somewhere closer to 2.5 on a longer-term basis is probably what we'll be looking at.

Okay, perfect. And then, last one, I think, you broke out the CapEx, it's going to be aimed at kind of new facilities, some of the truss -- if you see truss facility, more plants, truss lines and door machines. I guess, the question is, what's the incremental add look like 2019 versus what you just experienced in 2018? How much are you going to add to either each one of those or the total?

We called that about a quarter of our CapEx, another quarter of the 1.5% we think will be focused on those categories that I think you are outlining there.

And how does that -- what was the total in 2018 in those terms? About the same?

That's a good question. Probably about the same, maybe a little less, but right in there.

Okay. All right. Thank you all.

Moving next to Steven Ramsey at Thompson Research Group. Sir?

Good morning. I would assume …

Good morning.

… just thinking about your locations sort of on a portfolio basis as you continually access KPIs and the outlook of each. From that perspective, did you close any locations last year or open any? And do you expect anything on that front this year? And kind of how do you look at the penetration of value-added products penetration in locations? And the revenue capacity and generation of each -- I guess just kind of thinking locations bases or where you want to be?

So, I guess, I can open it and then sure Chad will probably want to jump in. But the decisions about opening and closing facilities in the given year, yeah, we opened I think two this year and closed two this year. So, we're continuing to modify. We closed an operation in East Hartford Connecticut I think. And one in Oklahoma City, but kept others in Oklahoma City. We're constantly sort of looking for opportunities to take out businesses where the return isn't where we need it to be and add locations where we think either a greenfield or a product specific location might help about -- with regard to capacity. On the value-add side each line each type of equipment has certain capacity availability. And that's where we flex, right? If we got a location it starts to run up against capacity constraint, but has manual equipment, we can move that manual equipment out to another location and bring in automated equipment and add a bunch of capacity into a locale. A little trickier around the lumber side. Your footprint matters or things you can do to improve efficiency, but there is some real space constraints that will limit the amount of dollars you can put through a facility. And that falls into the decision-making. We go through regularly about where do we need to add either square footage or acreage in order to run the business. It is an ongoing decision. And it is one of the things that we've really started to analyze a couple of different ways, right? We, of course, manage it on an EBITDA basis, on an EBIT basis, but also we're looking at it on an ROIC basis in order to make sure we're making wise decisions from a more strategic perspective.

Great. And then thinking about R&R slower in the Midwest, but broadly outside of the Midwest, is R&R activity performing more strongly when you look at it that way? And is your outlook from today thinking about 2019, is it more predictably good? Are you able to kind of quantify range on growth in that end market than you are with new construction?

I would say -- to answer your second question first, no, we are not quantifying growth in that space largely because of our geographic exposure being in the Midwest -- in R&R and other, in the Midwest in southern California and up on to Alaska. Those are sort of concentrated areas at least in the Midwest perspective, a lot of uncertainty candidly with regard to the U.S./China trade and the impact on ag soybean's important in particular. And the resulting sort of hesitation by certain markets to really get aggressive in some of their sales and some of their investments. Southern California is I'm sure everybody knows very volatile market historically. That's proven true in the last couple of years as well, so I'm a little reluctant to call a ball on that market, as well. And then unfortunately, Alaska despite the beginning of the recovery in oil prices in the fourth quarter are sort of pullback a bit. So we are -- there is a bit more wait and see up there as well. So, I'd say those are all reasons for uncertainty, not reason for optimism at this point, but we're going to wait and see.

Yeah, I don't -- wouldn't say the sky is falling, but the upper Midwest will be a challenge this year. I think Alaska will be a little better and Southern California is a bit of a question mark right now. So, I would echo what Peter said. Don't say it going gangbusters. It could be a little sluggish this year.

Great. Thank you.

Thank you.

And we'll go next to Kurt Yinger at D.A. Davidson.

Yeah. Good morning everyone and thanks for taking my questions.

You bet. Yeah.

I just wanted to start off on going back to gross margin. I did my math right. You're looking for 26% or maybe a little bit better in the first quarter. And you mentioned 25% is still kind of a reasonable normal figure. How quickly could we move back towards that as the year progresses? Is it something where you lose a lot -- about 100 basis points quarter-over-quarter in the first quarter and the same in the second, or is it may be more of a gradual step down?

Generally what we've said in the past and I think it's true still now is it -- it takes about a quarter or two to work through inventory on the ground and the pricing arrangements we have with our customers. So, I would say given that price has started running back up in Q1. Q1 and Q2 is where you're going to see the vast majority of the impact.

Yeah, I think it'll pretty much have played out barring some unexpected change by the end of Q2.

Okay. Very helpful. Thanks. And looking at the $65 million to $75 million sort of improvement now from operational initiatives returning to sort of mid-cycle building levels. Is there any way to think about that savings between cost of sales and gross margin versus SG&A?

I would say it's probably a third margin, two-thirds SG&A.

Okay. And lastly, what's a good way to think about interest rate -- interest expense for the year?

Yeah. So, our guide is about $95 million to a $100 million.

Okay. Thanks very much.

You bet.

Thank you.

That does conclude today's question-and-answer session. And I'd like to turn things back over to Mr. Crow for any additional or concluding remarks. Sir?

Well, thank you once again for joining our call today. We look forward to updating you on the progress of our initiatives in the quarters ahead. If you have any follow-up questions, please don't hesitate to reach out to Binit or Peter. Thank you.

And ladies and gentlemen, once again that does conclude today's conference. And again, I'd like to thank everyone for joining us today.
