Good day, ladies and gentlemen. Welcome to the Fastenal fourth quarter conference call. I would now like to introduce your host for this conference call, Ms. Ellen Trester. You may begin.
Welcome to The Fastenal Company 2016 annual and fourth quarter earnings conference call. This call will be hosted by Dan Florness, our President and Chief Executive Officer, and Holden Lewis, our Chief Financial Officer. The call will last for up to 45 minutes and will start with a general overview of our quarterly results and operations, with the remainder of the time being open for questions and answers. Today's conference call is a proprietary Fastenal presentation and is being recorded by Fastenal. No recording, reproduction, transmission, or distribution of today's call is permitted without Fastenal's consent. This call is being audio simulcast on the internet via the Fastenal Investor Relations homepage, investor.fastenal.com. A replay of the webcast will be available on the website until March 1st, 2017, at midnight Central Time. As a reminder, today's conference call may include statements regarding the company's future plans and prospects.
These statements are based on our current expectations. We undertake no duty to update them. It is important to note that the company's actual results may differ materially from those anticipated. Factors that could cause actual results to differ from anticipated results are contained in the company's latest earnings release and periodic filings with the Securities and Exchange Commission. We encourage you to review those factors carefully. I would now like to turn the call over to Mr. Dan Florness.
Good morning, everybody. Thank you for joining our call today. I'll start by just apologizing for the state of my voice on today's call. I'm recovering from a bit of a cold, so I'll try to speak clearly. My comments this morning will be relatively brief. I just want to touch on five points. First off, we had an upbeat finish to a tough year. Secondly, I believe we've changed the trends of our business. Third, I believe we've improved the health of our business. The fourth and fifth aren't comments so much on 2016, but I think they're comments that we should always remind ourself of. One is we have great people close to the customer. We have great people behind the scenes to support our local business. Those are structurally important components to the success of our business today, historically, and I believe going forward.
In regards to the upbeat finish, our sales trends and our gross profit stabilized and/or improved, depending on if you're looking at a comparison to Q3 or comparison to Q4 of a year ago, and we grew our earnings. For a new CEO, you can appreciate the importance that comes with having a release that doesn't have some either parentheses or dashes in front of a number or two after we've come through a, quite frankly, a pretty tough 2015 and 2016 period. Secondly, our trends have improved. In the last several years, primarily 2014 and 2015, we had significantly added people cost to our organization as we grew our headcount, primarily at the store, but throughout the organization. These costs, when I look at the trends that come with it, had about peaked in the second quarter of 2016.
As we have gone through the year, those costs have cycled down a bit, and I believe we are poised quite well to manage that expense as we go into the new year. We also have added occupancy costs quite dramatically in the last several years. A piece of it relates to our vending platform, a piece of it relates to the automation we put into our distribution centers, and a piece of it relates to our store network. There's always some built-in inflation in the store network, and our job every day is to manage that well. But whether it might be property taxes or some cam charges or some inflation in a lease, we have to be very mindful how we manage that in the long term, especially as the business is evolving.
Again, similar to the people cost, I believe we exit the year in a much better spot, but we still have some work ahead of us on the occupancy side of the equation, because we want to plan for and allow for growth there that comes from a continued expansion of our vending platform. In regards to business health, we upgraded around 2,100 stores to our CSP 16 format. While we haven't talked about it a lot on our calls, that's a tremendous undertaking when you look at our store-based business, and this 2,100 upgrade was primarily in our U.S.-based business. We have some upgrades for our Canadian business as we enter 2017. We also upgraded or optimized, if you will, over 50,000 vending machines. That's more about improving our cost to serve than it is about a revenue enhancer.
There's some revenue improvements because of it, but we had rapidly rolled out those 50,000-plus machines over the last five years. In 2016, we took the opportunity to go and visit each and every machine and to challenge how we could be more efficient with that machine. I believe that improves the health of that vending business and improves our ability to serve and grow the business in the future. We also changed our mindset over the last several years as it relates to Onsite. Our first Onsite occurred in 1992, and at the end of 2014, we had around 200 Onsites that we had slowly grown in our business. If I think of 2014, just under 5% of our district leaders, and we have today roughly 255 district managers across the company, just under 5% of them signed at Onsite.
We signed, I don't know the exact number, but it was around 14 Onsites that year. In 2015, we took a big step forward and around 25% of our district leaders signed an Onsite that year, and we signed around 80 Onsites. In 2016, Fastenal has a hallmark of finding great people, challenging them to be successful, but not micromanaging. In 2016, over 50%, I believe 54 is the exact number, but over 50% of our district leaders had an Onsite signed in their business, and that translated into 176 signings during the year. Our goal going into 2017 is quite simple, to keep moving that participation up and for 80% of our district managers or district leaders to have an Onsite signed in their district. If we're able to accomplish that, we believe we could sign somewhere between 275 and 300 Onsites.
We believe that's an achievable number from a signings perspective. It's an absorbable number from an execution standpoint, because very much of the work is spread across 255 business units, 2,600 stores, not concentrated in one small support group. We're very excited about that. We also believe with the CSP 16 in place, the team that helped roll that out is there to also help with the implementation of our Onsite. We believe we've improved our capacity to implement. Fourth, we talked about great people close to the customer. 75% of our employees know our customers on a first-name basis, and yet we have a very efficient cost structure. I don't believe any other nationwide distributor can lay claim to that, and we're proud of that fact. Finally, the team behind the scene. Our team is strong. We are wired for change, and we're frugal.
All of these things help us serve our customer well. I'll close with one thought. We believe in our people, we challenge each other to improve, and we challenge each other to grow each day. With that, I'm going to turn over to Holden, but before Holden starts in. This is Holden's second earnings call. Many of you know Holden Lewis from his previous career as a sell-side analyst. He'd covered us for quite a few years. We knew Holden well. We're not quick to bring in somebody from the outside into our organization in this senior of a role, but we really liked Holden's ability, we felt, to culturally fit with us, and the fact that he could bring a new set of eyes, a new critique, and a tremendous skill set to our organization. With that, I'll turn it over to Holden.
All right. Thank you, Dan. Good morning, and thanks for joining the Fastenal fourth quarter call. I'm going to begin with a quick recap of our full year 2016 results, and then I'll move on to a discussion of the quarterly performance. In 2016, Fastenal generated $3.96 billion in sales. That's up 2.4% from 2015. We did have an extra day in the year, so on a day's basis, we were up about 2%. I'm not going to belabor the tough conditions that persisted through the year. I feel like that's well understood by you, but I would like to highlight some of the drivers that allowed us to grow despite it. First, on vending, we finished 2016 with 62,822 machines. That's about up 7,300 units or 13% over 2015.
At this point, 46.1% of our sales now go to customers that use vending, so it's fairly well represented in the field. Revenues through our machines increased by more than 10% in the fourth quarter. Signings of 18,059 machines were up 1% year-over-year. Note that these figures exclude the nearly 15,000 units that we installed related to our leased locker program. Despite all those successes, vending did not quite reach the goals we'd set for it in 2016. Note that signings were at a three-year high, and we think that with the distractions related to our optimization efforts and the leased locker initiative now past us, we're targeting more than 20,000 signings in 2017. Secondly, on our Onsites, we signed 176 new agreements in 2016, a little shy of our goal of 200, but substantially above the 80 that we signed last year.
This frankly contributed to driving sales through these sites up at a better than 25% rate for the year. We're gaining momentum here, and we are targeting 275 to 300 signings in 2017. With respect to national accounts, we signed 190 new agreements. That's up 14% from 2015. Even with softness among our largest 100 customers, these signings contributed to our total national accounts revenues being up by a bit more than 4% on the year. We still see significant opportunity with new and existing customers, and even with national accounts now being about 47% of our total sales. Lastly, the SKUs related to our CSP 16 initiative, they also grew at a little bit better than a 4% rate in 2016. We feel good overall about the strides that we're making in our growth drivers.
We remain convinced of their effectiveness in driving share gains, and we look forward to further progress in 2017. Margins in 2016 were a challenge. Our gross margin finished the year at 49.6%. That's down 80 basis points, which is primarily from mix and pressure on product margins, the latter being particularly early in the year. Our operating margin finished 2016 at 20.1. That was down about 130 basis points. In addition to the gross margin decline, occupancy was up as we continued to invest in our vending initiative. We're likely to remain challenged by mix and vending-related occupancy, but some of the product pressures that we experienced in the first half of this year have eased at this point. We've been tighter with costs in the second half of 2016, and some of the minor expenses for things like store closures or CSP 16 rollout hopefully don't recur.
As a result, we think we're better equipped to defend our margin in a slow growth environment or even expand it if growth accelerates from here than was the case in 2016. Our interest expense on the year roughly doubled, while our average share count was down 1%. Both those facts reflect our share buyback activity over the last eight quarters. Our tax rate was down from 37.5% to 36.8% in the year, which really just owes to some jurisdictional shifts as well as the resolution of certain state tax matters. It all blended into a 2016 EPS figure of $1.73, which was down about 2.3% for the year. Moving on to the fourth quarter results. Total and daily sales in the fourth quarter were up 2.7%. That's a modest acceleration from the prior nine months.
We can't ignore the easier comparison relative to last year's fourth quarter, when our daily sales rate was actually down 2%. The December daily sales were up 3.2%, and that was likely understated because of holiday timing. In contrast to a poor November, frankly, we considered December to have been as expected. The details of the quarter remain a bit of a mixed bag. Growth from our top 100 accounts remained flattish on weakness among general industrial companies. The proportion of stores and national accounts that were growing in the fourth quarter was largely unchanged from the third quarter, and construction fasteners actually weakened in the period. In the end, growth of 1.6% in North America really wasn't much change from the prior period. On the other hand, it's notable that heavy manufacturing was up 2.3% in the fourth quarter.
That's the first time that's been up since the second quarter 2015. Similarly, OEM fasteners were weak, but the down 2.8% was also the narrowest decline we've seen since the second quarter of 2015. I would note that there is a more favorable tone surrounding process industries as we enter 2017. We're going to continue to assume the sluggish business conditions that have prevailed through 2016 are going to continue into 2017, and there remains a great deal of uncertainty on a number of fronts. With that said, the environment has become more optimistic. Our gross margin was 49.8% in the fourth quarter. That's down 10 basis points versus the prior year, but it's up 50 basis points against the third quarter. With respect to the year-over-year change, mix continues to weigh as the fasteners fell 180 basis points to now represent 35.6% of our sales.
Given this, we view the stability in the period favorably. There was no single meaningful offset. Rather, it was small improvements in areas like purchase discounts and freight that benefited the quarter relative to the prior year. As it relates to the fourth quarter, we were pleased to see the margin rebound from the third quarter of 2016. Similar to the annual result, this is less from a single item than it is from the accumulation of many small but favorable improvements, including better margins on non-fasteners, a higher mix of exclusive brands, building revenue associated with our locker lease program, better purchasing, and other variables like that. A lot of these things worked in our favor at the gross margin in the fourth quarter. There is nothing in this improvement that strikes us as one time or temporary in nature.
At this point, we would characterize the margin environment as stable. Our operating margin was 19.3% in the fourth quarter, also down 10 basis points on a year-over-year basis. SG&A as a percentage of sales was unchanged at 30.6% of revenues. Payroll, which is 65%-70% of our SG&A, was down 30 basis points as a percentage of sales. Persistently sluggish demand has had two effects here. First, they continued to temper the incentive pay in the fourth quarter. Second, we spent much of 2016 letting attrition unwind the rise in staffing we experienced in 2015. We finished 2016 with headcount being down 5.4%, or down 4.1% on an FTE basis. These variables more than offset the effect of higher health insurance costs. Occupancy, which is 15%-20% of total SG&A, was up 30 basis points as a percentage of sales.
Vending was the primary catalyst behind this, and we don't expect that dynamic to change in 2017. We did expect efforts to rationalize our store base in the second half of 2016 would provide a larger benefit than wound up being the case, and that's going to be a point of emphasis for our company in 2017. In 2016, we trimmed staffing in stores, we invested in growth drivers and technology, and used our balance sheet to invest strategically in inventory. We like where our cost structure sits as we exit the fourth quarter. We're going to continue to invest in our growth drivers, but given the investments and rationalization we've already made, we believe that with a little faster growth, we can leverage the income statement in 2017. Finally, we generated $133 million in operating cash in the fourth quarter. That's down 8.5% versus last year.
It also represents 116% of the quarter's net income, which was below last year. This decline year-over-year reflects three things. First, in the fourth quarter of 2016, we took advantage of favorable year-end buys. Second, our payables were much higher in the fourth quarter of 2015 related to adding CSP 16 inventory in that period. Third, our receivables fell at a faster rate in the fourth quarter of 2015 due to the relatively sharper pullback in demand in that period. These factors all serve to inflate the cash flow in fourth quarter of 2015 relative to fourth quarter of 2016. That said, we generated free cash flow after dividends of $18.5 million. Our capital expenditures were down 23% year-over-year and down 63% sequentially as we wind up the rollout of our locker lease program.
As a result, we reduced our net debt by roughly $21 million and retained flexible leverage of net debt being 12.5% of total capital. We expect cash generation to be improved and free cash flow after dividends to be positive in 2017. We don't anticipate a CSP program of the sort that we had in 2016. We expect capital spending to come in around $120 million. With that, we'll turn it over to Kevin to take your questions.
Ladies and gentlemen, if you have a question or a comment at this time, please press the star then the one key on your touchtone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. In the interest of time, we ask that you limit yourself to one question and one follow-up. Our first question comes from Robert Barry with Susquehanna.
Hey, guys. Good morning.
Hey, Rob. Good morning.
I guess the broader question is just to provide a little bit more color about what you're seeing in some of the key end markets, in particular, heavy and light manufacturing and oil and gas. Also more specifically, I noticed you updated the monthly sequentials.
I think if you plug those into the model, it implies 1Q growth would be just over 5%. I know that's not meant as an outlook, but is that how you're thinking that growth could track in 1Q?
To address your second question first. We all know how the math works. We've updated the sequentials. As we go into 2017, we're going to begin discussing those sequential rates of change in terms of the prior five-year averages as opposed to what we've done historically going from 1998 forward. The numbers are what the numbers are. I'll let you plug them in and kind of figure out where it is. I think that you're on the right track in terms of how that should fall out given those sequential rates of change. On the second question, where we saw the most encouraging signs, I would say, would have been in the process industries. We go about this a couple of ways.
We listen to our Regional Vice Presidents and what they're seeing in the marketplace. We look at our top 100 accounts to get a sense of which areas are doing well, which ones are not. What I would tell you is the general industrial companies on our lists, they're still challenged. That's been the case most of the year, and I'm not sure that I saw or have heard any meaningful difference in the fourth quarter as it relates to general industrial firms. As it relates to the process industries, I would tell you that a lot of those, including oil and gas, looked better among our top 100.
If you sort of listen to some of our RVPs talk about energy, there definitely is more of an enthusiasm, and some more encouraging facts on the ground in those regions that are heavier in oil and gas. What I would tell you is, I don't feel like the fourth quarter felt a lot different in a lot of places than what we saw in the third quarter, the notable exception would've been in those process industries in that oil and gas space. As you know, we were surprised by how impactful the decline in oil and gas was to us when it began to head south a couple of years ago. We would consider it a positive if in fact oil and gas had some legs and did better from here, we'll see how that plays out.
Right. Maybe just for my second question, just on the gross margin, nice sequential rise. You listed a number of reasons for the improvement, one of them was not price. I was just wondering if you can comment on what's happening in the pricing environment, and in particular, given we've started to see some inflation. In fact, I think we've seen inflation for several quarters now. How do you feel about the ability to start getting price, especially if some of these end markets are still a little sluggish?
Sure. We've seen the same thing that you have with respect to commodity prices. I would tell you that those increases are relatively new. We've seen it happen before, only to sort of retrace, if you will. I think it's probably premature to be saying that we have clearly entered a reflation period, if you will. That said, we're watching it, and we believe that if those raw material increases prove to be durable, we believe that as we have in the past, we will be able to pass that through price increases. Yeah, we don't have any reason at this point to think that that would not be a part of the equation. However, we have not, at this point, taken significant strides to begin that process yet.
Yeah. How much of a lag historically would there be? Like several quarters, or-
Hey, Rob
how do you think about it?
Rob?
Yep.
I'm going to chime in so we can keep going through the roster of your questions. Sorry.
Okay. Yeah, of course. Sorry. Thanks.
Our next question comes from Andrew Buscaglia with Credit Suisse.
Hey, guys. Congrats on a good quarter.
Thank you.
Thank you.
Yeah. You didn't have a ton of commentary, I guess, in the press release or your prepared remarks just on trends improving. Can you comment maybe what you're seeing through January? Just, it sounds like December was a little bit muddled with timing and stuff like that, but just any recent update would be great.
I'm going to just interject one thing and then I'll shut up and let Holden talk. In regards to January, we've learned over the years there are certain places you don't go because invariably what we talk about, we're always wrong. The question is how wrong. I'll stop Holden before he starts on the January piece. With that, I'll let Holden have a say.
Yeah. I don't think there's a whole lot to add. Yeah, we're not going to comment on January. We put out the sequential rate of change that we're sort of looking at. Beyond that, we're not going to go there. I'll just reiterate again, fourth quarter was a lot richer on optimism than it was real progress. We listen to the people in the field. We look at the same data that you guys tend to look at. It hopefully will translate into better results as we go through 2017. I'll just leave it as in fourth quarter, general industrial companies were still fairly slow. If there was a favorable inflection, it is in the process in the oil and gas industries. That's very early, so let's see how that plays out. I don't think that I noted anything that inflected negatively.
Okay. All right. Got it. Just switching onto the gross margins. Some of the things you had been experiencing with regards to negative customer mix, product mix, how are you feeling about gross margins in '17 versus '16, just relative to some of those sort of longer-term headwinds we had been experiencing?
If you think of the growth drivers we've talked about for a number of years, I always want to caution, our sales plan at the local level is what drives our business. The growth drivers that we talk about serves as the means to the end of how you serve your customer. I believe we had a very successful year on taking some first steps that started one and two years ago of expanding our Onsite presence. All those things continue a pattern that's been in place for 20 years. That is our mix of customers is continually changing. Our product mix continues to move a bit away from fasteners. Perhaps we can slow that down a little bit if there is some recovery that helps our faster business in calendar 2017. The underlying long-term pattern is still what it is.
What we need to be smart about every day is identifying those pieces we can grab onto and make a little. A decade ago, a piece we grabbed onto was freight. In the last five to seven years, a piece we've grabbed onto is our exclusive brands, our private labels, making sure we have a great strategy to support our supplier base and our product mix in serving our customers. The underlying trends are still there. We just need to defend the position every day. I think we gained some footing on that as we went through 2016. It was still a tough year to go through, '15 and '16, I should say, because the trend has been going on for several years.
Right. Okay. All right. Thank you, guys.
Our next question comes from Hamzah Mazari with Macquarie.
Good morning. Thank you.
Morning.
Morning. I just had a big picture question around the store network. How should we be thinking about the store network longer term, given the aggressive push on Onsite? Does Onsite cannibalize any of the store revenues? Just any color on that piece. Then you talked about participation rate going up with district managers on Onsite. Could you give some color on the sales cycle as well? Does it take a year, six months? Any color around the Onsite business would be helpful.
Sure. Probably the best way to think about the big picture from a store network standpoint is over the last 20 years, we've been quietly growing Onsite in some of our Midwestern business units. Last week I was in Southern Wisconsin, and all of our general managers were in. In that discussion, one of the things that stands out when I think of our business in Wisconsin and Illinois, over a third of our revenue in that business unit, about 35%, comes through the Onsite type of strategy, where we've been incredibly successful over time on developing our business in a broader fashion. If I think of that business over the last 20 years, we continued to open stores. We continued to grow our footprint, and some of that stemmed from the fact that we had things going on.
We had non-fasteners growing in our business, a lot of markets that traditionally weren't viable became viable. In more recent years, we made improvements from the vending side of the equation. We believe long term, it's a huge market out there, number one, and we espouse that often. We're not wed to one strategy. We're wed to getting close to our customer where it economically works and providing them a level of service that our competitors either can't or are unwilling to do. We believe it's a complement of both. Only time will tell if structurally the fact patterns of our industry change and it prompts our ultimate store count to go up or go down. The market is still there, and we need to evolve to serve that market. History has shown they're very complementary to each other, Onsite and store.
In relation to Onsite, it's typically a multi-year endeavor. Part of it is, it's like anything. It's incremental. When we move in, if you will, in the case of an Onsite, it depends sometimes on the product lines we're starting with. It might move faster if we're moving in with an OEM relationship or a broad vending platform relationship. It might move a little slower if it's a broader mix of products and we're picking up particular commodities as we go along. I believe it's probably, in many cases, a 2-4 year endeavor to get in deeper. Maybe it's 1-5, but it takes time, and that's one of the points that we stressed earlier in the year is we want to build momentum back into our business, and getting traction in the Onsite is a big piece of that.
Hamzah, you also asked something about cannibalization, in fact, we do, generally speaking, take some sales out of the store, and that becomes the seed revenue for that Onsite. What we find is that inside of 12-24 months, that seed revenue has grown dramatically from its original number. As it relates to the store, our expectation generally is that that store, which now doesn't have to provide a disproportionate service to a single customer, can sort of have its selling energy reinvigorated, then they can go out and from an admittedly lower base, begin to grow that business again. We've sort of altered the compensation with the Onsite business to make it neutral from that standpoint.
The expectation is that the store sort of no longer responsible for that piece of revenue will go out and find new active accounts and just begin to grow that business again from that new level.
I'll just throw one additional piece in. When I think of the cannibalization, that comment would've been true of store openings for the last 30 years as well. Onsite isn't a new piece of the equation. Really what we're doing, and I think Holden described it best, we're taking some seed dollars, for we have a great relationship, and we're going after business that historically our store network wouldn't go after because it wasn't geared to service that business given the profile of the gross margin in that business, and we need to structurally change our cost components to go after that business.
That's very helpful color . I appreciate it. Just to follow up, and I'll turn it over. How much of your cost of goods sold is foreign sourcing? A competitor of yours mentioned theirs is 15%. Just trying to get a sense of what you guys run at. Thank you.
What we have said is that we think that 40%-45% of our COGS probably derives from overseas. I don't know what the competitor, how he was defining the number. I will tell you that of that 40%-45%, not all of that is directly sourced. Obviously, we have a significant operation with Fastco that directly sources product, but that does not rise to near the level of 40%-45%. The number that we use includes not only the directly sourced, but also that product that we may buy domestically, but ultimately is sourced from an overseas customer. We talk about it in terms of 40%-45% of our COGS, and that's kind of how we've discussed it.
Got it. Makes sense. Thank you.
I'll add on one piece there as well. The fastener production moved offshore of North America. Fastenal, in 2017, we're celebrating our 50th year in business. Largely, the trends within fasteners were moving offshore well before we even became a company. A lot of that was driven by the automotive sector back in the late '50s and early '60s. Our percentage is a little bit higher because of the fastener concentration in our business. With that said, our concentration wouldn't be any different than any of our peers in the industry, given similar product mix. I see us as being in a similar boat, if you will, with everybody else, with a lower cost structure in our underlying business.
Got it. Thank you.
Our next question comes from Ryan Merkel with William Blair.
Hey, thanks. Good morning, guys.
Hey, Ryan.
Morning.
First, Holden, you said, with a little faster growth, you could leverage the income statement in 2017. Two questions. What level of sales growth do you think you need to see SG&A leverage? Secondly, is SG&A growing half the rate of sales in a reasonable goal in 2017?
I don't think that our original guidance was changed. I think we said that at sort of low to mid type of revenue growth, that we'll look to sustain the margin, and if we can get mid to high type of growth, we can expand it. I still think that that is, generally speaking, where we see the model. In terms of the rate of growth of SG&A, bear in mind that if we do in fact get better growth, we would expect to see our incentive comp go up. We're going to continue to invest in vending. We have talked about achieving 20%-25% type incrementals in sort of a low to mid type single digit growth environment and maybe 25-30 type incrementals if you get into mid to high.
That was sort of where we were, I think, in third quarter, and we haven't seen anything that sort of changes that.
Perfect. Got it. Okay. Then second, back to the Onsites. How are the installations you've done working, and how much did Onsite add to growth in 2016, if you have that number handy? Because I think you were hoping for maybe 300, 400 basis points of growth from Onsite this year.
The Onsites grew as a category about 25% for the year.
That's including the transferred cannibalized dollars.
Correct. That's the challenge, right? We're up 120. Tell you what, why don't we talk about the specific numbers offline? We have them. I'm not going to do the math on this forum. Why don't we touch base on it offline.
No worries. You've signed up a lot of Onsites. Are they working as you expected? Are the stores starting to add new active accounts with the freed up selling energy?
I'll answer that from the standpoint, we took a deep dive look at the Onsites that had been turned on and had sufficient history. For us, sufficient history meant they had to be operating at least nine months. We looked at that to see what's happening in that group. We liked what we saw. We weren't surprised by what we saw. We saw a group of accounts. The numbers that we really analyzed, it was just over 50 of our Onsites that had been operating long enough that we could really get a feel for it. The trends were solid. It wasn't driven by a few that were pulling it up or pulling it down, which is good to see. It was a good performance, generally speaking, across the group.
We saw that the gross margin of the store that spawned, I don't know if that's the right word, that spawned the Onsite business, their gross margin went up post separating the business, which is what we would expect, because typically you're taking a larger customer, it might be a $10,000, a $20,000, a $30,000 a month customer, and you're extracting it from a $100,000, $120,000, $150,000 store. The remaining business actually has a slightly higher gross margin. We saw that as we expected. We saw that business with a lower gross margin than our average Onsite. That is very typical because oftentimes when you're stepping into a new Onsite, you're stepping into some products that you might be not sourcing optimally yet. You might not truly understand some of the products from the standpoint of, it gets back to that optimal sourcing component.
You might have product where you know the optimal source, but you aren't going to get the product in for three, four, five, six months, and so you have some lower margin sales that are going out. You might have some product that the customer had a meaningful supply on, and you don't pick up that business for a period of time. When I look at those Onsites that we've studied, again, we were pleased with the results and weren't surprised by the results. I suspect when Holden runs his numbers, he's going to find a low single digit, probably a one to two kind of number, given the fact that so much of our business was ramping up in the latter half of the year. Obviously, Holden has an-
Yeah.
During the call.
The incremental revenues through Onsite would have increased our revenue probably a little bit over 3% for the year.
Fair enough.
Do remember that does include some cannibalization that would take that down a little bit. That's the total number. The Onsite revenue did in fact, contribute a little more than 3% of our growth for the year.
I would suspect it would probably cut it by a third to a half.
Yeah.
Okay.
That's probably about right.
Okay. That's very helpful. Thank you.
You bet, Ryan.
Our next question comes from Robert McCarthy with Stifel.
Good morning, everybody.
Hey, Rob.
Hey. Just following up on a couple issues. I suppose first, just maybe Holden, you could talk about the process industries and oil and gas, and maybe give us some sense of what you think the exposure is, just maybe walk us through the number of stores in the right regions. Give us a sense beyond kind of the SIC codes of how big the overall exposure could be to your network for sales.
Yeah. The direct impact is fairly light. I think we've talked about sort of low mid-single digit direct impact from the oil and gas industry. You're right to say that the impact is really more indirect. I'm not sure that we've really sort of come down exactly on sort of a number we think it is. It clearly does matter and perhaps Dan can give more historical perspective, in terms of what the full year impact is. Bear in mind that where that full year impact comes from, companies like Flowserve or Weir Group that are not oil and gas companies, if you will. They're pump companies or engineering companies, but they have significant exposure to the oil and gas within their overall customer mix. That's where our exposure comes from. The challenge in figuring out the full exposure comes from that fact.
Dan, do you know kind of what a full year indirect impact might be?
In the past, I think we've talked about a number somewhere between 10 and 12%, it's really difficult to pinpoint it because there's so much indirect impact.
Well, yeah.
The example I've often cited is if I travel an hour and a half upriver to visit my mom, there are two sand mines within 2 miles of the farm I grew up on. They both were operating 2 years ago. The one was operating 24 hours a day. The other one was operating 16 hours a day. One of them has shut down, the other one has one shift. Our Red Wing store was impacted by oil and gas, I wouldn't have thought of our Red Wing, Minnesota store as having an impact of oil and gas. It's very hard to sift it out.
Okay. Well, Holden, perhaps we'll table that for a little probing offline. The second major question for this call is maybe just talk about Onsite. I mean, obviously people have been talking about the opportunities there in terms of what's going on, maybe just talk about really how important it is from an optimization of a network potential. I think you've cited in the past, at least anecdotally, how high the margin is in your legacy stores in kind of your Berk to Skadden, which is the upper peninsula of the Midwest and Minnesota, in terms of where the margins are. Could you just talk about really what you think the margin opportunity long term could be for the company, at least qualitatively, given Onsite?
Well, I'll throw out a few pieces we'll wrap the call because we're running up against 45 minutes. For us, profitability at the end of the day really stems from where's our average store size in that region and how well are we doing managing the growth of our business over time. If I look at the Midwest, where we have the greatest concentration of Onsite, it's also an area of the country where we have the largest average store size because it's grown over time because our West Coast started opening up 20 years ago. Our Midwest started opening up 50 years ago. We have a 20 to 30 year head start. Our highest operating margin business is in the Midwest.
With that said, one thing Bob Kierlin has always reminded us in the 20 years that I've been here, and probably in the 50 years that he's been here, is at the end of the day, gross margin is a marker we look at to understand our business. Operating margin is a marker we look at to understand our business. Great organizations long term focus on where they can provide their employees with an opportunity, their customer with a service, and their shareholders with a return on investment. We like the various businesses within Fastenal because they all provide a very attractive return, and that is, at the end of the day, the ultimate test of a business. If you're providing opportunities to your employees, you have a great organization to serve your customer long term.
We believe we have all those components in our store network and in Onsite. With that, I see we're at 45 minutes and similar to prior quarters, we realize we're in the thick of earnings season and everybody has a pretty busy plate. We'll sign off for now. Again, thank you for your support of Fastenal, and thank you for welcoming Holden to the team.
Thank you.
Ladies and gentlemen, this concludes today's presentation. You may now disconnect and have a wonderful day.
