Management

Good morning and thank you for joining us today for AutoZone's 2018 first quarter conference call. With me today are Bill Giles, Executive Vice President and Chief Financial Officer and Brian Campbell, Vice President, Treasurer, Investor Relations and Tax. Regarding the first quarter, I hope you have had an opportunity to read our press release and learn about the quarter's results. If not, the press release along with slides complementing our comments today, are available on our website, www.autozoneinc.com. Please click on Quarterly Earnings Conference Calls to see them. To begin this morning, I want to thank all AutoZoners across the company for their tremendous efforts this past quarter. The quarter started out with Hurricane Harvey and finished up with five more natural disasters across North America causing our AutoZoners and customers living in those regions tremendous disruptions in their lives. From hurricanes to earthquakes in Mexico, the wildfires out west, we incurred costs and property damage in each one. While we were able to get back on our feet quickly with Hurricane Harvey and Irma incurring minimal damage to our stores, Hurricane Maria hit our stores and customers hard in Puerto Rico. We have 43 stores in Puerto Rico and unfortunately we still have several that are unable to open due to damage incurred. Our thoughts and prayers continue to go out all the folks on the island for the horrible effects this storm has had on their lives. Our AutoZoners throughout the organization have responded incredibly well and swiftly so that we have been able to get the vast majority of our stores opened very quickly following these disasters. So our AutoZoners could service our customers when they needed us most. Our support for our AutoZoners and customers in Puerto Rico continues so we can aid them in…

Bill Giles

Management

Thanks Bill and good morning everyone. To start this morning, let me take a few moments to talk more specifically about our retail, commercial and international results. For the quarter, total auto parts sales, which includes our domestic, retail and commercial businesses, our Mexico and Brazil stores and our 26 IMC branches, increased 5%. For the trailing 52 weeks ended, total sales per domestic AutoZone store were $1,770,000. Total commercial sales increased 6.7%. In the quarter, commercial represented 19% of our total sales and grew $31 million over last year's Q1. We opened 30 net new programs versus 35 programs opened in our first quarter last year. And we now have our commercial program in 4,622 stores or 84% of our domestic stores supported by 188 hub stores. Over 700 of our programs are three years old or younger. In 2018, we expect to open approximately 150 new programs. As Bill mentioned earlier, we remain focused on growing this business as we see this business as our most significant growth opportunity and we are treating it accordingly. We are committed to having a great sales team, supplemented with stronger engagement of our store managers and district managers. We remain confident we will continue to gain market share with our commercial customers. We are encouraged by the initiatives we have in place and feel we can further grow sales and market share While we have completed the majority of our commercial project and we have some new thoughts and concepts, they are just that, ideas. We will now move to implement and test these on a small-scale in order to refine and enhance them. For competitive reasons, we won't be sharing our detailed findings at this stage. Once we have proven concepts with concrete plans, we will share our plans but…

Bill Rhodes

Management

Thank you Bill. While we are encouraged with the start of our fiscal year, we are careful to not over-commit to any outcomes when it comes to our second fiscal quarter. The second quarter has perpetually been our most volatile quarter due to weather patterns, the holidays and timing of tax refunds. Last year, we were impacted negatively by the delay in income tax refund and the impact of a second consecutive mild winter. We did not foresee the impacts on sales these events would have on our business for the second and third quarters last year. While we are pleased with our progress and the acceleration in our business, we want to highlight some of the potential points of volatility, both positive and negative, in the upcoming quarter. One, if we experience a cold and high precipitation winter, our sales should be strong later in the quarter and into the balance of the year. Two, tax refund timing should be the same as last year. So it shouldn't have any bearing on our second quarter's results. As for Q3, we don't know if those sales will return. Three, as the holidays shift, we will loose two selling days in our DIFM business, which will negatively impact our sales growth in DIFM. It's important to note that this has an insignificant impact on our DIY business. Fourth and we encourage you to be mindful of the significant EPS benefit due to stock option exercises in the second quarter of last year and adjust for this non-operating unpredictable event. We are excited about our balanced model for growth around domestic, retail, commercial, international, online and pickup in store. We believe our hubs and mega hubs, Mexico, ALLDATA, e-commerce and our other businesses can all grow their toplines in 2018. To execute…

[Operator Instructions]. Our first question is coming from Alan Rifkin of BTIG. Your line is now open.

Alan Rifkin

Analyst

Thank you. Congratulations on a nice quarter. Bill Rhodes, certainly you expressed your enthusiasm about the mega hub strategy. What's the revenue lift to your store base once they move to being supported by a mega hub? And then related to that, what is the average revenue per store on for these stores versus stores that are still not supported by mega hubs? Thank you very much.

Bill Rhodes

Management

Yes. Thank you for the comment, Alan. I would say that the mega hub service in and of itself can drive between 1% and 2% growth in the local store. As far as the volumes go, the volumes are all over the spectrum, because we are trying anybody that's within a reasonable service area, we are providing service to them from mega hub. So they may be on the low end of the scale or they may be on the high end of scale. But generally they will grow between 1% and 2%. Some of the factors within that depend on whether or not they are serviced multiple times a day or once a day or serviced on an overnight basis. A big part of our strategy now as we mentioned, about 4,000 of our domestic stores already have mega hub service. But many of those today are only getting it on an overnight basis. As we continue to expand our mega hubs, which by the way we couldn't be more pleased with, as we continue to expand it will have more and more that will get same-day service versus overnight service and some of those will even get multiple times per day service from that mega hub. So it's all part of our objective to enhance inventory availability across the local marketplace.

Alan Rifkin

Analyst

Okay. Understood. And a follow-up if I may, Bill. With respect to your vendor base, what, if anything, are you now seeing in terms of more vendors possibly taking Dorman's lead and implementing MAP pricing in terms of e-commerce? And what has its effectiveness been thus far?

Bill Rhodes

Management

Number one, we have had many vendors that have had MAP pricing or some form of MAP pricing for years, if not decades. Dorman recently, I believe they went in October, so I think it's a little bit too early to tell what happens. They are making those decisions on their own. We certainly support our vendors in a way of making sure that there is price transparency and we are all providing great values to our customers over time. But that's their decisions, not ours.

Alan Rifkin

Analyst

Thank you. Best of luck for your happy holiday season.

Bill Rhodes

Management

You too, Alan. Thank you.

Operator

Operator

Thank you. And our next question is coming from Christopher Horvers of JPMorgan. Your line is now open.

Christopher Horvers

Analyst

Thanks. Good morning. So I wanted to follow-up on the mega hub commentary. What's the gating factors on service in the store, same day and multiple times per day? Is it cost? Is it systems? Is it that you just don't have the right facilities? Can you talk about that? And maybe sort of quantify as you move from an overnight to a same day and multiple times per day, how does the business respond?

Bill Rhodes

Management

Sure. Thanks for the opportunity to clarify that, Chris. It's an excellent point. So one of our mega hubs, for instance, is in Los Angeles. Today that store may be providing service to San Diego but it's doing it on an overnight basis. As we potentially build a mega hub in a San Diego type market, then all of a sudden those stores can move from overnight service to same-day service. It's simply the proximity of this location of the store to the mega hub. It's got to be, if they are within 100 miles, we might be able to service them three times a day. If they are 200 miles, we might be able to get there one time a day. If they are 400 miles, we got to get there overnight.

Christopher Horvers

Analyst

I understand. And so I think long-term you have talked about perhaps 40 to 50 mega hubs and, I think, you are around 18 right now. So how does that two-thirds of the stores being fulfilled -- sorry,. maybe one-third filled in the same day, how does that progress over time? And if you get to 45 to 50, what's the service look like to the stores on a same-day basis?

Bill Rhodes

Management

Yes. We haven't laid it out because part of it is, we are looking and learning about the economics of this as we go. As you mentioned, we have 18 today. We said in our prepared remarks, we are going to 25 this year, hopefully if we can get them all open. That's our plan. But when we originally rolled it out, we said 25 to 40 and we have made a small tweak in what we were saying, we don't talk about 25 anymore because we are going to be there by the end of the year. We say up to 40 and the more we learn about it someday that number could go up as well. It's been on of those initiatives that continues to outperform our expectations. And as it outperforms our expectation, it allows us to expand it further. But I also think it's important to understand we are also not competing in a stagnant environment. Our competitors are also, be them the public companies that you are accustomed to or the warehouse distributors, everybody's changing their operations and we are looking at ways to enhance our competitive position.

Christopher Horvers

Analyst

And then the last question I have, is there anything as you look at the tax bills that are in front of the House and the Senate, is there anything in there that could be either positive for you, I understand the corporate tax expense, the potential corporate tax benefit, but is there anything in those bill that concerns you from a financial or business operation perspective? Thanks very much.

Bill Giles

Management

Sure. Yes. I don't think there is anything in the tax bills that we are aware of today that would concern us per se. Obviously as you mentioned, the tax rates being lower on a corporate basis for most retailers will be very beneficial. And so we expect it to be a positive. We will wait and see what ultimately comes out of committee and what gets signed including the timing of the implementation and plan accordingly. But certainly from a capital allocation strategy, we expect our strategy to continue to remain intact and feel really good about it.

Christopher Horvers

Analyst

Thank you. Have a great holiday.

Bill Rhodes

Management

You too.

Operator

Operator

Thank you. And our next question is coming from Matt Fassler of Goldman Sachs. Your line is now open.

Matt Fassler

Analyst

Thanks so much and good morning. My first question relates to the sales outlook. I think on last quarter's call, you as a company offered a somewhat subdued perspective on the sales potential for the business. I am understanding that you have got a bit of a bump from the hurricane, the sales accelerated nicely. They recently exceeded Wall Street expectations and you are talking about the potential for the business to pickup, I am not sure if it's off current levels or from prior assumptions, if the weather turns seasonable in the fourth quarter rather in the calendar fourth quarter and into winter. Anything change in the backdrop or anywhere else to alter your read on your prognosis of the forward here? Or is it just that the business did pickup and showed its potential? Is there something else happening in the world that drove your incremental enthusiasm here?

Bill Rhodes

Management

Thanks Marr for that question. I think it's a great question. If you will recall on the last quarter, I talked about the fact that the perception of our industry's performance over the last two or three quarters was that we had reached a new all-time low in performance. And I was very careful to talk about that. But that truly wasn't the case. So if you looked at our industry's performance or AutoZone's performance over a five or 10 year period of time, that our performance last year was operating within the normal bands of what we have experienced. They were towards the lower end but it was not -- we weren't dealing with catastrophic performance. I cautioned everybody because with that notion of, oh, things are so bad, then all of a sudden they are going to, the pendulum is going to swing and they are going to be fantastic. We went and said, no. We believe they will get better and operate in this normal band. I think I talked about, we were like 140 basis points below our average for the last five years. And so we would translate, yes, we think that they will improve particularly when some of these factors, these macro factors that we can't do anything about, like two mild winters and the late tax refunds, once those normalize we should we believed and continue to believe we would go back to that normal band. Now in Q1, we outperformed our expectations. But part of that outperformance was the 50 or 60 basis points from the hurricane impacted markets. But we are pleased with the performance that we have seen in our store's sales, both on the retail and particularly on the commercial side in Q1. But I was also very intentional about making comments about Q2 only because Q2 is incredibly volatile. If the weather hits and hits at right time, our sales could be really strong. If we have a third consecutive mild winter, it will take some momentum out of it. We just have to be careful and part of what I am trying to say is, let's understand that Q2 the very low volume quarter. We are closed a few days during the quarter. It's our lowest one quarter of the year and I, for one, don't want to put too much focus on Q2. If we get a strong winter, we believe Q2 and the latter part of Q2 will be strong and more importantly we believe the balance of the year will be more positive. But we also continue to believe that we will operate in a normalized band that we have been in for five or 10 years.

Matt Fassler

Analyst

No, that's very helpful. Quick follow-ups to that. On the storm sales, was that kind of a one-time pop? Or is there any spillover into subsequent quarters in your view?

Bill Rhodes

Management

I think there will be a little bit of spillover into Q2 from it, Matt. What generally happens, when the storm hits, we are closed for days. And so we actually take a net negative for the first week or so. And then as the markets began to recover, we see increased economic activity and it lasts for three or four months. It depends on the order of magnitude of the store, but we would expect to see some benefit, probably not a benefit that we would be calling out on the next quarter, but some benefit early in the second quarter.

Matt Fassler

Analyst

Great. And then finally, while you are clearly testing and probing a lot with supply chain absent from the dialogue this quarter was the impact to gross margin of excess supply chain costs. So should we consider that chapter essentially closed and no longer look for much gross margin impact from that?

Bill Giles

Management

Yes. I wouldn't categorize it as closed, per se, Matt. But you are totally right. We have anniversaried a lot of the impact that we have had and so we expect to see more normalized going forward. And I think the supply chain team has done a terrific job of managing it in spite of opening two distribution centers over the last six months.

Matt Fassler

Analyst

Thank you very much guys.

Bill Rhodes

Management

Thank you.

Operator

Operator

Thank you. And our next question is coming from Simeon Gutman of Morgan Stanley. Your line is now open.

Joshua Siber

Analyst

Good morning. It's Joshua Siber, on for Simeon. Can you talk about what's driving the commercial improvement? Whether you can parse it out between industry growth versus internal drivers?

Bill Rhodes

Management

Yes. I think I haven't seen enough and it is very hard to see the industry growth perspective on commercial on a short term period. Over the long term, we believe we have a pretty good handle and it's growing around 4.5%. In short terms, it's hard to see that. I think what is improving in our performance is our team's core blocking and tackling is getting better. We have been talking a lot about getting the store managers and the district managers more engaged in the business. And I think that that's helping over time. Our sales teams continue to get better and better. And inventory availability were the biggest reason we are doing the mega hubs and the MFD to try to spur on commercial growth. And I think those efforts are beginning to help us in commercial. I think it's also important to highlight, we grew almost 7%. So we are close to 2X the growth of the market.

Joshua Siber

Analyst

Okay. And my follow-up, you mentioned if we return to more normal weather. So I am curious how you would characterize the winter so far?

Bill Rhodes

Management

Well, I don't think you need to even try to characterize it. We are not running this business for a couple. We are 2.5 weeks into our quarter and who knows what's going to happen. So it will start getting cold this week. It's not about what happens between Thanksgiving and December 15, it's really what happens from December 15 to February 10. That will really be the deciding factor.

Joshua Siber

Analyst

Okay. Thanks a lot.

Bill Rhodes

Management

Yes. Thank you.

Operator

Operator

Thank you. And our next question is coming from Seth Sigman of Credit Suisse. Your line is now open.

Seth Sigman

Analyst

Thanks a lot and good morning. One question just on the cost side. So your expenses grew roughly 5.5%, excluding the hurricane. I know you talked about a number of future headwinds and you talked about that last quarter as well. I am just wondering, is this the run rate to think about? Does this 5.5% essentially capture those headwinds? Or is there a reason to believe there would be a further step up at some point?

Bill Giles

Management

No. We think that that 5% range captures those headwinds. And those headwinds are, as Bill talked about before, you have got a little bit of wage rate pressure that continues to exist although the team has done a terrific job of managing our way through that and we have a little bit of occupancy pressure as you are seeing that coming from mega hubs and hubs as well as we are seeing rising real estate tax costs across the country as well. So those are some of the things that are little bit of headwinds. We think we can manage our way through those. But I think that that's a pretty good run rate to look at.

Seth Sigman

Analyst

And do you start to lapse some of that in the second half of this fiscal year? You did see a pickup in expenses late in your last year.

Bill Giles

Management

I think late in the year, we will start to lapse some of that.

Seth Sigman

Analyst

Okay. Great. And then my follow-up is just around pricing. I am wondering, are you starting to see any signs of inflation? Did that impact the quarter at all? And just in general, a lot of talk about price transparency in the category and in retail in general. Do you feel like if you see inflation you will be able to push that through?

Bill Rhodes

Management

We have historically. To answer the first part of the question, we haven't seen a significant amount of inflation and frankly we haven't for probably a couple of years now. And so historically, we have had been able, as an industry, to push much of that cost along to the consumer. So today we don't see that changing necessarily but we will have to wait and see when it comes.

Seth Sigman

Analyst

Thanks very much.

Operator

Operator

Thank you. And our next question is coming from Michael Lasser of UBS. Your line is now open.

Michael Lasser

Analyst

Good morning. Thanks a lot for taking my question. Bill Rhodes, you mentioned that Midwest and the Northeast continue to underperform. Yet the business accelerated in large part because of the commercial program. Should we take that to mean that your commercial business within those underperforming regions also underperformed? And why would that be the case?

Bill Rhodes

Management

So I think, number one, both parts of our business saw acceleration during Q1. Commercial is a little bit more visible to you because we call it out specifically. But both of them improved in Q1. As we look at what's going on with the industry, part of what's happened is those mild winters have put less strain on the under car components. So think about chassis and brake components and shocks and struts. That didn't go away when the summer went. That lack of wear and tear has continued and those jobs are done, by both DIYers and DIFMers. So that's why it impacts both markets in a similar fashion.

Michael Lasser

Analyst

My follow-up question is on the potential for a sharp reduction in your tax rate. If that happens, how would you think about the prospect of returning the benefits back to shareholders versus redeploying the savings back into the business?

Bill Giles

Management

Yes. I think that we kind of think about it as we feel good about our capital allocation strategy. That remains intact. It served as well over time. We will continue to invest in those initiatives that we believe will result in adequate returns to the corporation overall. We will continue to invest in our infrastructure and we will continue to execute our capital allocation strategy. Time will tell. I mean the bill hasn't yet. So we will have to wait and see what's in the final bill and the timing of it.

Michael Lasser

Analyst

I guess that was less referring to capital allocation and more so the margin structure of the business. If your earnings growth is going to sharply accelerate, would you look to the maybe slowdown that earnings growth acceleration?

Bill Giles

Management

Well, of course, the earnings growth will be below of EBIT. So the question really is, you are asking what's going to happen below the EBIT line. And obviously that's going to increase. But we don't see, from a tax perspective, something changing fundamental to the operating margin of the organization.

Michael Lasser

Analyst

Okay. That's very helpful. Thank you very much.

Operator

Operator

Thank you. And our next question is coming from Matt McClintock of Barclays. Your line is now open.

Matt McClintock

Analyst

Yes. Good morning everyone.

Bill Rhodes

Management

Good morning.

Matt McClintock

Analyst

Bill, I am just trying to conceptualize the volatility in the business due to weather. As we think about the potential for weather to finally cooperate this quarter and maybe going forward, is that something that would potentially drive a closing of the 200 basis point gap in those regions that you are experiencing this year? Or is that something that could actually drive a closing of the multiple years of gap that you have in those regions relative to the company average?

Bill Rhodes

Management

Yes. I think there is no question about it. And as I mentioned, those are really good markets for us and historically really good markets. But because the weather patterns can be so extremely different, they are more volatile. It's not as predictable as California, for instance, where the weather patterns are pretty predictable what you are going to get. You don't know what you are going to get in the Upper Midwest and therefore we just have to deal with it. There is nothing that we can do to plan our business any differently or anything like that. We just have to ride the storm, on both the good side and the bad side.

Matt McClintock

Analyst

Okay. And then I think you were pretty clear about online competition and there's nothing really to see there. But could you maybe talk about nontraditional competition in the brick-and-mortar channel, big-box competition or other non-specialty auto parts stores?

Bill Rhodes

Management

Yes. I guess I would say, it's very similar to what we said about online, the mass merchants, they have been competing in our industry for longer than I have been here. And so I haven't seen any significant change in how they are going to market or impacting our business one way or the other.

Matt McClintock

Analyst

Thank you very much for the color.

Bill Rhodes

Management

Yes. Thank you.

Operator

Operator

Thank you. And our next question is coming from Dan Wewer of Raymond James. Your line is now open.

Dan Wewer

Analyst

Yes. Thanks. Bill, since 2009 AutoZone's gross margin rate has increased about 260 basis points. Do you think there is a gross margin expansion thesis going forward? Or do you think that current gross margin rates, maybe give or take 10 basis points, is what the next, say, three or four years with look like?

Bill Giles

Management

Yes. I think as we think about it, Dan, we think of it more positively than that. And so we continue to believe that there are opportunities for us to expand gross margin. Certainly, as we continue to increase some of our direct import initiatives, that will help reduce some of our acquisition costs. And so we continue to believe that there are opportunities to lower acquisition cost. There will probably continue to be opportunities to optimize the expenses, both in supply chain and in shrink. But we will always continue to have some pressures from a competitive set and an industry set relative to promotions, et cetera. So I think overall we are somewhat bullish relative to gross margin going forward. And if you look over time, you are right, we have done a terrific job in spite of a lot of things going on of continuing to increase our gross margin. So it remains healthy and we feel positive about it going forward.

Dan Wewer

Analyst

And then just a follow-up question on the sales benefits from the mega hubs. I think in response to Alan's question, you talked about a one or two percentage point benefit. Is there a difference if the store is getting same day coverage from a mega hub compared to the next day example that you talked about with San Diego?

Bill Rhodes

Management

Yes. There certainly is a difference, Dan. It's probably not as big as you would expect, because you have got to remember, these SKUs that we are talking about are really on the tails of the bell curve and so having them available even for next day, they will be there first thing in the morning and when you talk about some rural markets or those kind of things, that's pretty amazing that we can get them there. So there is a difference, but it's not 50% or so.

Dan Wewer

Analyst

Okay. Great. Thank you.

Bill Rhodes

Management

Yes. Thank you.

Thank you. And our last question is coming from Steve Forbes of Guggenheim. Your line is now open. Steve Forbes, your line is now open.

Bill Rhodes

Management

Let's go and take the next question.

Operator

Operator

Thank you. Our next question is coming from Mike Baker of Deutsche Bank.

Mike Baker

Analyst

Worked out well for me. I wanted to follow-up on Mr. Wewer's question and Bill Giles, your answer about gross margins continue to have some pressure from a competitive set and industry set relative to promotions. Is that changed at all with some online guys doing a little bit more in your business? Or is that sort of the outlook you have always had?

Bill Giles

Management

That's the outlook we have always had. I wouldn't say that we have seen any change necessarily from that perspective whatsoever. I was just trying to balance out the positive aspects of gross margin offset by some of the pressures that you might always consider. But overall, again, we continue to believe our margin remains seeing positive outlook.

Mike Baker

Analyst

Yes. Okay. Thanks. That makes sense. Two more quick follow-ups, if I could. One, you said, I think it was Bill Rhodes who said at one point that if the weather cooperates you would expect trends to get better in the back half of the quarter. Is that just simply a function of, you just have much more difficult compares, as I recall, from last year earlier in the quarter and the compares get much easier in the second half? Or is there some other reason why weather would only impact the back half of the quarter?

Bill Giles

Management

I think and I said the back of the quarter and also the balance of the year. So last year, we did get a cold snap and it was December 1 to Christmas. And so we had some real strong sales during that period of time and then it got warm. Also, so if the weather hits, it's going to hit a little bit later than it did last year and we should see the strength in the back half. The other part of it is, there is kind of the tale of two stories on what happens with this extreme winter weather. One is, when it gets really cold really fast, we get an immediate bounce on our business like in batteries. But what happens over time in the longer tail on the winter is, when the road conditions get bad, we will get a longer tail on under car parts, chassis, breaks, ride control, those kind of things. Those are things that you wake up that day and your car can't get you to work, those are things that they put more stress on the components and so the maintenance cycles accelerate. So that will put a tail not only for the back half of Q2 but on into Q3 and some into Q4.

Mike Baker

Analyst

Okay. That makes sense. If I could ask one more quick one here, but hopefully a quick answer. But with some of the pluses and minuses on the gross margin that's described in wages and other costs higher, what kind of sense for sales numbers do you need to get back to a double-digit earnings growth and let's assume that the tax rate stays similar to where it is now. Because obviously, if it goes to 20%, you are going to greater earnings 10% or higher. But let's assume that doesn't happen.

Bill Giles

Management

Yes. We are not really, we don't think about on a same-store sales basis like that, Mike. And everybody wants to be able to think through that way. I think we are just thinking about there is opportunities for us to improve gross margin. We talked about the operating expense growth rates. And so, just those are the ways you should be thinking through your model overall. But I mean, look, we feel great about the health of the industry. We feel good about the momentum that we have got. And so we are encouraged by the business.

All right. Before we conclude the call, I would like to take a moment to reiterate that our business model continues to be very solid. We are excited about our growth prospects for the year. We will not take anything for granted as we understand our customers have alternatives. We have a solid plan to succeed this fiscal year but I want to stress that this is a marathon and not a sprint. As we continue to focus on the basics and focus on optimizing long-term shareholder value, we are confident AutoZone will continue to be very successful. We thank you for participating in today's call. And we would like to wish everyone a very happy and healthy holiday season and a prosperous new year. Thank you for your time today.
