Michael J. Kneeland - CEO, President and Director
Thanks, operator, and good morning, everyone, and thanks for joining us on today's call. We have a lot to cover today, starting with a strong second quarter. Our results reflect some of the best fundamentals we've seen in years, and some of that's external but a lot of it comes from executing well as a company. I also want to talk about market demand, which has been stable at a high level, and we have some thoughts on how 2017 and 2018 will play out. And then there's the guidance that we gave an update last night.
So let's start where we are today. Now I want to mention 4 metrics that are especially meaningful and then Bill will discuss them in detail in the quarter -- for the quarter. Now one metric is our volume. Pro forma, for NES, volume in the second quarter was up 6.6% and we had a similar increase in the first quarter, which points to a healthy marketplace.
Rates, another good story. We achieved positive rate trend across our business in the quarter with sequential improvements each month, and we're very close to being positive on our rate year-over-year. But don't expect us to rest. Rates will continue to be a major area of focus for us. Our employees understand how critical it is as part of our strategy.
Importantly, we gained around rate, we also increased time utilization to a new record of 69.4%. This is the highest time utilization of any second quarter in our history. In fact, each month set a new record.
And finally, our free cash flow through June stands at a robust $614 million, which is right on track, and that's after $968 million of growth CapEx spend. These are excellent metrics that show how effectively we are running the company. Our people are out there every day, managing the business with discipline, right through the height of the NES integration.
Now one thing you'll notice as we go through the call is that we're no longer talking about stand-alone NES and United Rentals. While the integration is ongoing, we are now operating as one organization, and we've made a great deal of progress on the $40 million of cost synergies we identified in April, as Bill will discuss.
Now I'll give you some of the operational milestones. The back-office, sales and operational teams -- operating teams are now fully integrated and their branches have moved on to our management systems. We're in the process of training our new employees on Salesforce.com and our rate management tools. We're rolling out route optimization technology for equipment deliveries, and dispatcher training is underway. We're also installing telematics on the acquired fleet. We're about 10% through the retrofit program with telematics installed on over 2,500 machines.
But one of the most important parts of the integration has nothing to do with equipment. Back when we bought NES, we noted that our 2 companies shared a strong safety culture. Well, I'm pleased to say that last month, we had the safest June on record. We recently finished a series of town hall meetings for over 1,000 employees in our combined company. For some, this was the first town hall and their first chance to meet company executives. And we opened these meetings with comments on safety, operational excellence, technology and communication. And as always, our employees are not shy about voicing their opinions. I was pleased to see so many different perspectives put out there, and we're always willing to change how we do things if there's a better way and the town halls help us get there.
So NES has turned out to be a strong fit, and we bought them at the right time. Now our performance this quarter was about more than NES. Our entire industry is in a growth cycle. Customers need more equipment, and we're in front of them with a bigger fleet and a larger footprint. Key indicators, such as the Dodge Momentum Index, the ABI and construction backlogs, are all positive. Spending on commercial construction remains strong, and the forecast for the U.S. equipment rental industry overall is continued growth over the next few years.
The 2 former drags on demand have turned a corner. One is upstream oil and gas where the inflection point we saw last quarter has been sustained and the other is Canada. Western Canada seems to have stabilized and the Eastern provinces are growing strong. Nationally, rental revenue was up 7.3% in the quarter and volume was up 8.8% with improving rate trends. That's the strongest growth we've seen in Canada in 8 quarters. In the U.S., our largest revenue gains continue to come from 2 coasts. In New England, for example, more than $5 billion of large projects are either starting or ramping up in the third quarter, following a strong spring. These range from casinos and plant expansions to office complexes. In the West, we're seeing multiyear projects for entertainment venues and large corporate campuses. And in the Southeast, it's automotive plants, data centers, infrastructure and manufacturing.
Another important indicator is our customer confidence index. In June, the level of optimism remains strong, with the majority of our customers indicating that they expect their business to improve over the next 12 months, and we've arrived to the same conclusion. In our opinion, the cycle has substantial runway ahead.
Now turning to specialty. Our Trench, Power and Pump segment continues to outperform, underpinned by strong organic growth. In the second quarter, the segment revenue increased 19% year-over-year, primarily on a same-store basis, and gross margin improved by 250 basis points to 49.6%.
Our Pump Solutions business had an outstanding showing with revenue up more than 37%. Now some of this is due to the rebounded upstream oil and gas but they're also getting traction on other verticals. Now we'll continue to expand our specialty networks with a total of at least 17 cold-starts this year, 7 of those are operating now, bringing our specialty footprint to 224 locations out of a total of 960. Our specialty cold-starts hit the ground running in part because many of our existing accounts need solutions that are outside the scope of general construction. This helps to differentiate us as a premium rental provider. 4 years ago, in 2013, specialty accounted for 10% of our rental revenue in the second quarter. This year, the number was 19%. So specialty rentals are becoming increasingly important to our business.
Another initiative that's well timed for the up cycle is Project XL. Project XL is a toolkit of work streams focused on driving improved profitability, and we're targeting $200 million of run rate by year-end 2018. Now all the pilots are complete and we're phasing them into operations.
Now before I hand it over to Bill, I want to spend a minute on guidance that we issued yesterday. It raises our 2017 outlook for revenue, adjusted EBITDA, capital spending and free cash flow. We're confident that the market will support our higher expectations for revenue and EBITDA, and we've allocated another $100 million of CapEx to ensure that we can meet that demand. It helps that our industry continues to be more disciplined about fleet purchases and the supply of available rental equipment is being absorbed in the marketplace.
Now when we look at third-party data, we're encouraged by the broader industry is getting rate improvement. As long as growth in demand continues to outpace new supply, our rate dynamics are likely to benefit. So I hope my comments this morning can convey not only the broad scope of the opportunity ahead but also how well positioned we are to take advantage of it.
The decisions we make are designed to balance growth with margins, free cash flow and returns to maximize our long-term value. In the second quarter, we showed that we can achieve this balance across the business. Now as we enter the busiest period, we see even more potential to convert our strategy into value for our shareholders. So with that, I'll ask Bill to cover the numbers and then we'll go to Q&A. So over to you, Bill.
William B. Plummer - CFO and EVP
Thanks, Mike, and good morning to everyone. As Mike said, we got a lot of information this morning on the second quarter, a lot going on in the quarter. I'll try to give you my normal color on the information that we usually report. We've also had a lot of questions about NES and the impact there. So we'll try and carve out where we can information there that will give you a sense of how NES is going for us.
Let me start though, as usual, with rental revenue in the quarter, $1.367 billion, was up $163 million or 13.5% over last year. The components driving that were -- we'll start with the ancillary revenue, had a good quarter there, with ancillaries adding $21 million over last year, really driven by volume, partly from NES but just the raw volume of more fleet on rent as well as higher revenue from delivery and fuel associated with rentals. Re-rent was a positive too year-over-year, basically volume-related there as well. But the bulk of that $163 million was the owned equipment revenue growth. Within that, $140 million from OER growth. $181 million is the contribution from volume. So really strong quarter in getting more fleet on rent. Rate costs, that's about $13 million of decline year-over-year, that from the 1.2% reported decline in rental rates versus last year.
Our replacement CapEx inflation was $16 million in the quarter and then that left $12 million of unfavorability from mix and all other, and there's a lot going on within the mix and other column this quarter. You'll see that when we get to the bridge for EBITDA year-over-year, the addition of NES as well as other mix factors by cat class and period mix.
So those are all the key components to the revenue change year-over-year. Let me just take a minute to say a little bit more about our rate for the quarter and the impact of NES within that rate. It's a very difficult question to try and address how much did NES impact our rate for the quarter. Obviously, the 1.2 as-reported decline in rate reflects the fact that we didn't have NES in the last year period but we did in this year. And as you all know and you've heard us say before, NES rates came in lower than United Rentals' rates and so it had a drag effect on the reported 1.2% decline. You can see that by comparing that 1.2% decline to the pro forma rate performance, which was a 40 basis point decline, with pro forma being defined as NES was put into the last year period as well as this year period. So that difference just gives you a sense of how much the addition of NES rates weighed down the as-reported number. When we dig in and try and identify exactly what happened to the NES rates period-over-period, what happened to the legacy United Rentals rate period-over-period, it becomes very, very difficult to really carve things out that way.
We've integrated NES very rapidly. The fleet has moved tremendously. We've consolidated branches and all of that just makes it really hard to say what's NES and what's United Rentals, but we still wanted to give you an indication. So what we did was we looked at the regions in our business, our U.S. Gen Rent business, where there was no NES impact. And we had 3 regions where there was either exactly 0 or very close to 0 impact from adding NES: our Pac West, our Midwest and our South regions. For those 3 regions, when you look at their year-over-year rate performance, they were down 0.3, very similar to the overall pro forma decline of the total company. So that gives us a sense that we were moving rates effectively in the right direction, both for areas that were impacted by NES and areas that were not. In fact, if you look at the months of the quarter and look at the monthly sequential rates for those 3 regions combined, it was a pretty solid month. They had in April sequential of 20 basis points positive, 70 basis points in May and 120 basis points in June. So nice improvement in rates even away from where we had impacts from NES. Hopefully, that gives you a little bit more flavor for what the rate picture looks like both in the areas affected and the areas not affected.
Let me move on to used equipment sales. $133 million of used proceeds in the quarter, that was essentially flat with last year and delivered an adjusted gross margin of 52.6%, which was up robustly 4.8 percentage points versus last year. Here again, there's an impact of NES we just wanted to try and call out for you. Within the $133 million of proceeds was included $15 million of proceeds from the sale of what had been NES equipment. That accounted for about $32 million of original cost equipment from the NES sales. That NES sale impact we estimate at something like $6 million of benefit to the adjusted gross margin. So that will give you a sense of what happens when we're selling the NES fleet, which, as I'm sure most of you know, typically is older fleet. They operated with an older average age of the fleet. So it generated more robust margins than maybe we'd have got out of our legacy United Rentals sales. They also had a more rapid depreciation schedule that also contributed to the book value being lower and therefore the contribution to adjusted profit from used being higher.
All of the sales continue to happen in a robust market environment. Our pricing experience is still pretty good within United Rentals and that compares to market pricing that our indication is, is still pretty good as well. In fact, in the quarter, we sold equipment at a little over 89.5 months of age, and we still realized 54% of the original cost for the sales this quarter. So a pretty robust pricing environment for used equipment sales overall.
Let me move to our adjusted EBITDA performance in the quarter, $747 million in the quarter. That's up $68 million compared to last year, and the components of that $68 million increase were as follows. Volume, again, the big story, $121 million positive over last year, only offset by that roughly $13 million of rental rate decline that I called out in the revenue bridge. The ancillary gains contributed about $11 million at EBITDA, and they were just about enough to offset the fleet inflation headwind that we normally experience. That fleet inflation was about $12 million of headwind in the quarter.
Used equipment sales year-over-year contributed $7 million. We did have our normal merit increase. That was a headwind of $6 million. We did, also in the quarter, have a bonus accrual increase as we adjusted our bonus programs to reflect the better performance of the company year-to-date and what we expect for the full year. That increase in bonus accrual cost us about $14 million compared to last year. Earlier in the year, we said that -- back in the first quarter, we said that we thought that the bonus accrual adjustment this year would cost us about $27 million over the entire year, $27 million. Our view now is that it will be more like a $38 million impact for the entire year compared to last year. And again, that's reflecting the improved performance of the business overall.
The last piece of the bridge to $68 million was mix and other, and again, that's a complicated story this quarter given the addition of NES fleet and NES transactions to our results. NES revenue came in at a lower average dollar ut. NES revenue came in with all of the NES fixed costs, and all of those things count against the mix and other. So mix and other was a decline year-over-year of $26 million versus last year, which made up the last piece of that $68 million year-over-year change.
Let me take a minute here to try and carve out the impact of NES at revenue and EBITDA, just to give you a sense of how it's playing through the quarter. Again, I'll emphasize that this is a very challenging thing to do because of the integration. But what we did here was to look at the individual assets that were brought in with the NES acquisition and track those assets to get a sense of the revenue they generated during the quarter. So when you do that, you get a rental revenue impact from those assets of about $87 million. Now obviously, you can debate all day whether it's just tracking the assets will give you the real revenue impact of adding NES, but we think that's the fairest way that we can think of to try and categorize what the revenue impact is. So $87 million of rental revenue impact, and then beyond that, we'll add to it the $15 million of used equipment revenue that I called out earlier and then we had $3 million or so of other revenue gains from the NES addition. So all together, that's $105 million worth of revenue that came with the NES acquisition or were the direct result of the acquisition.
It gets harder to say what that means in adjusted EBITDA terms, obviously, because it gets difficult to allocate cost and to carve them out specifically to NES exclusive, right? It's easy to do in an NES location, but when the fleet moves, how do you allocate cost? Still, we took a turn at it just to have a framework for thinking about the EBITDA impact, and we come up with a number that's about $46 million of adjusted EBITDA that we would attribute to NES. So $105 million for revenue and $46 million for EBITDA.
If you look at the flow-through in the quarter, our flow-through for the total company was 38.6% year-over-year. And obviously, if you use those NES numbers for revenue and EBITDA, you can back those out to get a sense of the flow-through of the company when you exclude the NES impact. That number calculates out to about 31% flow-through in the quarter. And I know some of you are thinking, okay, 31%, that's not great for the business ex NES. What's going on? Well, I'll remind everybody that, that flow-through is impacted by the rate performance of the legacy business. It's impacted by the differences in used equipment sales this year compared to last year. It's impacted by the differences in the amount of other lines of business revenue and profitability this year versus last year. And of course, it's impacted by the $14 million of the incremental bonus accrual that I talked about previously. If you take an estimate of all of those factors, which we did, and add them back as appropriate to the legacy URI business, you get to a flow-through that looks a lot like the 60% that we've always talked about. So our feeling, bottom line, is that the business is performing well, both for the legacy URI business and the NES added business, and we're going to continue to look for improvement still.
Let me move real quickly to cash flow. Free cash flow in the quarter was $614 million, as Michael pointed out -- excuse me that's year-to-date, as Michael pointed out. That's down from last year by $178 million. The big driver there was the increase in rental CapEx. Our gross rental CapEx was $913 million year-to-date period and that alone was up $190 million. So that was the biggest driver. There were puts and takes in other areas. Obviously, EBITDA improved. Our interest expense improved, but our cash taxes went up, as you all remember, that we burned off our NOLs during the course of last year.
That cash flow picture brought our net debt for the quarter at the end of the quarter to $7.9 billion. That was up from last year and it was up from where it was at the end of last year. And the primary driver of the increase, obviously, was the addition of NES, the purchase of NES offset by the free cash flow that we've generated so far year-to-date.
Let me touch on Project XL real quickly. As Michael mentioned, we're making good progress there. We have the 8 work streams well underway, some of which had pilots ongoing that now have been completed. And we feel good about what they're delivering in terms of the impact versus what we had in our targets. We took a turn at giving you a little bit more information about 2 of the work streams in our investor deck. I'll point you all to those -- to that page and those work streams. One is the growth in infrastructure vertical and the other is just driving -- continuing to drive our labor productivity, and certainly, we can address it in Q&A if you have questions. But the big message is that we're on track to deliver the $200 million impact from these initiatives that we talked about at our Investor Day, that run rate by the end of 2018. I will remind you, I said this back in December, this is not $200 million of incremental EBITDA that you can just add on top of what you otherwise would model. Some of these initiatives are a part of how we're going to continue to drive profit improvement in our company, and so you need to carve out which ones are add-ons and which ones are just part of the ongoing base business. And as we get further into that, we'll talk more about how you might frame that.
On the NES integration, just real briefly there. It is very -- going very well, as Michael mentioned. We're on track to deliver the $40 million of cost synergies by the end of '18 that we called out at the deal. And based on the actions that we've actually taken so far this year, we would say that we've realized in the second quarter about $2.5 million worth of synergies from those actions. And the run rate, as we sit today, is nicely on the path to delivering that $40 million by the end of next year. We should realize this year something between $15 million and $20 million of actual impact in 2017. And again, that's including the $2.5 million that we already realized in the second quarter. So well on our way on the cost synergies. By the way, also on the procurement savings that we called out, we gave the $5 million to $10 million range at the deal, and we believe we'll be at the higher end of that range when it's all said and done.
Let me finish up real briefly with our guidance. You've all seen the numbers, so I won't repeat the numbers. But just regarding the changes, just looking at the midpoint changes for total revenue and adjusted EBITDA, total revenue went up $175 million, adjusted EBITDA up $78 million at the midpoints. The big driver of both of those increases were rate and time -- or rate and volume, I'll say. Obviously, you see it in the numbers in the bridges for second quarter and year-to-date. Our expectation is that those will continue to be the big drivers for the remainder of the year. There'll be puts and takes and other ins and outs but it's really going to be a story about rate and time. The $100 million of gross capital that Michael mentioned that we're adding, we added to both ends of the range, but you really should think about $1.6 billion as being our focus target for CapEx this year. And obviously, as we always have, we will be very mindful to not spend that if we're not seeing the performance of the business shape up the way that we would like, and neither will we be afraid to come back and move it higher if we see the business performing better than our expectation right here and now.
And then finally, on free cash flow, the $25 million increase just reflects some refinements of our estimates, as we refine our views of cash taxes and working capital are probably the primary changes along with the operating profitability improvement that we pointed to.
It's a lot, I know, but we certainly wanted to give you as much information as we could in a complex quarter. It was a good quarter, though, and one that we're very pleased with, and look to continue that momentum as we go into third and fourth quarter.
So with that, I'll stop my comments and ask the operator to open up the call for questions and answers. Operator?
Operator
(Operator Instructions) Our first question comes from the line of Ross Gilardi from Merrill Lynch.
Ross Paul Gilardi - Director
Look, this time last year, you guys got a little bit of pricing for a couple of months and then it just sort of tracked seasonality for a while. What, if anything, is different this time and why?
Matthew J. Flannery - COO and EVP
Hey, Ross, this is Matt. It's a fair question and one that we've asked ourselves to make sure that we maintain the momentum. I would say what's different is a couple of things, number one, and most importantly, the demand environment and not just for us but what we're seeing in the industry. Information that we're looking at looks like absorption continues to drive positive in the industry, which is a good indicator. The other thing is the record time utilization that we're experiencing. And then thirdly, we have growth this year and we didn't have this kind of growth. And whether you want to use the stand-alone or the pro forma number, that was not really the same story last year. So there's a lot of indicators as well as a strong end market macro environment that we feel is -- should be very, very helpful to maintain the momentum that we have versus last year.
Michael J. Kneeland - CEO, President and Director
Yes, Ross, I will only add that last year, we were going through really still adjusting to the fleet imbalance, and we're in a much better place as an industry today.
Ross Paul Gilardi - Director
Got it. And then just a follow up. You guys have acquired NES and there seems to be a lot of midsized M&A happening. I mean, does it feel like we're on the cusp of a more substantial wave of consolidation in this space?
Michael J. Kneeland - CEO, President and Director
Ross, I've always said that consolidation would continue to play out inside of our industry. It's very fragmented. I think it speaks more to people have strategies as we do and they all do as well. The market cycle, I think, it speaks volumes that their belief that the market cycle is still there. And I also sit back and say, from a strategy point and from an industry point of view, having increased professional management, I think, will overall be a benefit to the industry collectively.
Operator
Our next question comes from the line of David Raso from Evercore ISI.
David Michael Raso - Senior MD, Head of Industrial Research Team and Fundamental Research Analyst
It's been probably 2.5, 3 years since you've had at the same time year-over-year growth in utilization rate and CapEx. And it looks like we're about to -- we're on the cusp of getting back to that. You haven't done that since like 2013, 2014, and you were doing 60% incremental EBITDA margins. So as much as I appreciate pull this out, pull that out, you say we're kind of doing that right now. But still, it is what it is, right? Incrementals right now are 30% to 40%, 50% if you want to pull out the bonus accrual. But still, the power of having those 3 things going the same direction into '18, can you try to handicap for us how we should think about incremental EBITDA margins and why they wouldn't be materially stronger?
William B. Plummer - CFO and EVP
Sure, Ross. I think, materially stronger, obviously, would be the result of on all of those things going together throughout '18, as you said, and rate will be an important driver there. How much of a rate improvement could we see in '18, I think, would be the critical question about how the flow-through might trend throughout. It's -- look, I mean, the analysis that we did, there were a lot of assumptions to it. So I don't want to go too far with the specific about 60% statement that I made. But at the same time, if we get rate to be mildly positive, if we continue to improve utilization, although that's a big ask given the record nature of what we're doing now, but say we improve it just marginally, and we're putting more growth capital into the business, again, that's an assumption, not saying we're there yet, but if all those things are lining up, 60% is -- I wouldn't say a given but it's certainly the starting point of the discussion about where flow-through could go next year. All of that, of course, needs a market that will support all of the assumptions that I just went through.
David Michael Raso - Senior MD, Head of Industrial Research Team and Fundamental Research Analyst
Yes, I'm just trying to set up a base case. Because I mean the pushback could be, well, back then, you were getting a lot of rate and some utilization. That mix next year, it's probably hard to assume the same kind of rate growth as you had back then. But that said, you also have some fodder for cost improvement with NES and so forth. So not to ask you to give '18 CapEx guidance right now, but can you help at least sort of frame how should we be thinking about growth CapEx or total CapEx, however you want to describe it, for '18 just for a base case?
William B. Plummer - CFO and EVP
Yes, David. It's still early for us to be thinking about that. We're talking about that. We're certainly thinking about it as we speak. But I would say that if the momentum this year continues into -- late into the year, I think it's very reasonable to say that 1,600 is the starting point for the discussion, right? And then we'll see where we go from there.
David Michael Raso - Senior MD, Head of Industrial Research Team and Fundamental Research Analyst
Last quick one then, Bill. In the month of June alone, we're talking pro forma on rental rates, were there any regions or how many of the regions, what percent of the regions actually were already positive on rate year-over-year for just the month of June pro forma?
William B. Plummer - CFO and EVP
For month of June pro forma, year-over-year, I can quote the sequential, but the year-over-year in the month of June, yes, it looks like it's 5 of the regions that were positive and 4 of the ones that were not positive, another 3 or 4 were reasonably close to breakeven.
David Michael Raso - Senior MD, Head of Industrial Research Team and Fundamental Research Analyst
And remind us, you run the company with how many regions exactly?
Michael J. Kneeland - CEO, President and Director
18?
Matthew J. Flannery - COO and EVP
13.
William B. Plummer - CFO and EVP
13.
David Michael Raso - Senior MD, Head of Industrial Research Team and Fundamental Research Analyst
13. So basically 5 out of 13 up, a few more kind of flattish and the other ones are still the drag, okay.
Operator
Our next question comes from the line of Tim Thein from Citigroup.
Timothy Thein - Director and U.S. Machinery Analyst
Again, just to follow on, on that last point. Can you quantify within the total what the 2 drags, as you called out earlier. This is not a region comment per se, but just energy and I guess do you find that is branches that are in those heavy oil and gas regions? And then I don't know if you can extend that to upstream, but if you kind of bucket energy as a broad kind of segment and then just Canada as a whole, just given that the movement in the currency, I'm guessing we shouldn't just use the difference between the 7.3% and the 8.8% that you outlined. So maybe just help us in terms of those 2 drags that you called out in terms of what they detracted from rates in the quarter.
Matthew J. Flannery - COO and EVP
Sure thing, Tim. This is Matt. I'll answer the upstream conversation first. So as you can imagine, as we've seen land rig count continue to climb, our upstream business has climbed. So we were up 68% year-over-year in Q2. That brings us to just under 5% of our total portfolio. So to answer your other question, if you look at our total energy exposure, we have about 5% of our business in upstream, about a little less than 2% in midstream and about 7% in the downstream business. So that nets to a little under 12%, technically 11.5% of what you would call energy exposure. And we're very, very comfortable at that level and encouraged to see the upstream. We've seen a lot of pickup in our Pump business specifically in that sector as well as other verticals within the Pump business. As far as Canada, our Canadian business is kind of a tale of 2 cities, but all of the provinces actually had some growth. We're a little bit more challenged in Alberta. When you look at the country as a whole, our rental revenue was up 7.3% and that's on almost 9% -- just under 9% volume but still over 3% rate drag year-over-year on that business, but we feel really good about Eastern Canada and we feel that the other provinces in the Western Canada have bottomed out and some are even moving forward a little bit. So we're encouraged by that.
Timothy Thein - Director and U.S. Machinery Analyst
Okay. And Matt, just can you remind us how quickly you would expect to reprice the NES book? I'm guessing that -- a little shorter contract duration than maybe the legacy URI. But can you just update us there in terms of the repricing opportunity with NES?
Matthew J. Flannery - COO and EVP
Yes, we're not really looking at it as just repricing NES. When we look at our pricing, it makes us a little bit unique as far as in customer buckets, geographies and products. As so we're not really parsing out the NES. There are some key accounts with NES that we will treat probably a little more gradually just as we would our key account business at United Rentals. But overall, we're looking at these customers blended. We're merging our rate zones, we're harmonizing our pricing and we're merging customer accounts. So it won't be long before we won't even really be able to identify them as NES and United rates. We have a rate strategy as a company that's based on the segments we talked about and we're going to deploy that across the board.

Our next question comes from the line of Joe O'Dea from Vertical Research.
Joseph O'Dea - VP
First question just on the specialty side, and I appreciate that we're right on the heels of NES. But as you see in the headlines, a little bit stepped up activity on the M&A front. Just what you're seeing on the landscape there. In the 2018 plans you had talked about back in December that included some inorganic growth in specialty, and so just kind of where you're seeing that environment right now?
Michael J. Kneeland - CEO, President and Director
Well, first and foremost, we don't talk about the acquisition other than the fact that we do have very robust backlog of things that we're looking at. With regards to specialty as a whole, as you can see going from 2013 to today in second quarter from 10% to 19%. And the growth capital that we're putting in there, along with the cold-start, we have a very firm strategy of growing that business and we're going to continue to fund it. I think it differentiates us in a different way and our customers obviously are very open to it. But we're always looking. We're always looking both for market opportunity. We're looking at potential acquisitions, and we're also looking at different product mixes that we could do within the specialty group. So it's all of the above but it's going to continue to grow.
Joseph O'Dea - VP
And then the -- in terms of just tone of the industry, it looked like the survey results maybe stepped down a little bit. Not sure if that's just having run-up and then come back down, but maybe just to kind of address what we're seeing in the reported survey results and then in general kind of what you're hearing from customers and some of the confidence that contributing to seeing 2018 positively?
Matthew J. Flannery - COO and EVP
Yes, I would say we continue whether it's a customer index, whether it's any of the macro data we look at or whether it's the intelligence we gain on absorption of fleet and rate improvement in the industry, everything is pointing to a strong environment for the balance of the year, and we see that playing into 2018. Those are the -- that's the framework in which we're making our business decisions and we really haven't seen much to challenge that. There may be a pocket here and there by sector or by vertical, but overall, we're very encouraged with the demand outlook for the future.
Michael J. Kneeland - CEO, President and Director
Yes, and just to be clear on the -- our customer index, if you're referring to that, it is strong. March was unusually strong, and therefore, it made it look like it was dropping. But in fact is it is very strong.

Our next question comes from the line of Nicole DeBlase from Deutsche Bank.
Nicole DeBlase
So my first question is just around the revenue outlook. And I know you guys are refraining from providing explicit rate guidance, totally understand that. But is there any way you can kind of frame the way the back half plays out according to the low end and high end of your guidance with respect to like normal rate seasonality? Like this is a normal seasonal outcome? Is it better? Is it worse?
William B. Plummer - CFO and EVP
Nicole, it's, as you can imagine, challenging when we don't want to be explicit about rate and time guidance. What I would say is that we are not making heroic assumptions about where rate goes in the back half of the year in that revenue guidance. It's well within the range of sequentials that we assume as well within what we've done historically. And so we feel like we've got a comfortable set of assumptions there. That's about as far as I think we should go.
Nicole DeBlase
Okay, that's really helpful actually. And then secondly, just around the CapEx, the increase in the full year guidance. Can you just talk a little bit about the, like, equipment categories or the priorities of spending for that new incremental bit of CapEx?
Matthew J. Flannery - COO and EVP
Yes, Nicole, this is Matt. I would say that it's going to be fairly consistent with what our fleet profile is. We'll continue to put about 20% of that incremental capital into our specialty business, and specialty will continue to grow a little bit faster than our Gen Rent. As you look at Q2. We think that'll continue. When you look at the rest of the mix, whether you're trying to model whether it'll be more aerial or more dirt or more of the other, it will be across the board, very similar to our fleet profile as a company.
Operator
Our next question comes from the line of Seth Weber from RBC Capital Markets.
Seth Robert Weber - Analyst
Just going back to Tim's question first. Is there any way to frame kind of what the starting point is here for the delta between URI's pricing and the NES pricing? Just so we understand kind of where you're starting at and where NES prices could come up to. And also as kind of a tack on that, if there's an average length of NES contract?
William B. Plummer - CFO and EVP
Yes, it's challenging to think about how to frame the impact beyond what we gave already, right? I think I recommended to somebody last night that if you sit down with a simple spreadsheet and make some reasonable assumptions about what the share of business that NES contributes both this year and last year, you can frame out sort of in broad terms how to get to that 0.4 pro forma number and how that compares to the 1.2 as-reported number. The actual assumptions that go into your spreadsheet about sort of the relative rates of NES versus us, we've characterized broadly in the past as being double digits, the difference. So that's the starting point, obviously, with United Rentals being the premium. And that gives you a sense of, over time, how much of a gap there is to bridge. How much of that gap we actually bridge and how quickly we actually bridge it, time will tell. But that's the field that you're playing on, sort of a double digits kind of number that we're working to make, make sense for our customer base as we go forward.
Seth Robert Weber - Analyst
Okay, that's helpful, Bill. And then there's been a lot of discussion around the industry about mix, right, and big industrial contracts and whatnot. Can you talk about the competitive rate environment, specifically going after these larger, bigger, longer-term industrial contracts, what that looks like today?
Matthew J. Flannery - COO and EVP
Sure, Seth. This is Matt. I mean it's, depending on what markets you're in and what customer you're going after, and the volume, these are always competitive. So the good news is they don't go out for bid regularly, and we have been the incumbent in many of these, and that gives us a lot of credibility. So we're comfortable with our positioning. It doesn't mean that we can ever take any of it for granted, and this business will always have somebody wanting it and that's part of being a leader in the industry. There's always someone that wants what you have. That's nothing new for us. It's something that we're very comfortable with. And I wouldn't call it out any more or less competitive in -- whether it's a national account sector or whether you're fighting to get more share in an MSA. So we feel comfortable with the level of competitiveness. We're encouraged by the level of responsibility from an absorption and rate improvement that we see in the industry as well.
Michael J. Kneeland - CEO, President and Director
Yes, the other thing I would add to that is the onus is on us to make sure our value proposition is such that we meet or exceed our customer expectations. And that's why we talk about our specialty, you talk about the capital that we're spending, you talk about the digital and things that we're doing with Total Control, finding ways to assist our customer to be more of a partner and find ways to drive productivity and safety. That's what we need to do and that's what we need to keep focused on. And we've got -- we're very good at that and the team's really focused on it.

Our next question comes from the line of Jerry Revich from Goldman Sachs.
Jerry David Revich - VP
I'm wondering if you folks can talk about how you're thinking about adding capital into the oil and gas-impacted regions. Obviously, big swings in the rig count, and how has your risk appetite around capital deployment in those areas changed as we're clearly ramping up short term here?
William B. Plummer - CFO and EVP
So Jerry, much of our growth has really come from absorption. As we had talked about in the past, and probably the biggest example of it is our Pump business, we made a decision a couple of years ago to hold on to some assets that we knew had a lot of life left in them. We mothballed them and we're really getting the benefit of that decision today when you see the type of growth that we're getting in that Pump business. And those are the type decisions we made overall. We didn't expect to run 80% time ut in oil and gas markets so when -- any more after it turned. So if we were willing to leave our footprint there, de-fleet enough to keep some capacity there, it gave us the opportunity to respond to this growth, and I think that's where we are today where we aren't having to dump a lot of fleet in there to drive that growth. And it feels good, a little bit of self-congratulations here, admittedly. But it feels good to have put in that faith and commitment and to be able to benefit from it so...
Michael J. Kneeland - CEO, President and Director
That said, we learned a lesson last time, right? And so we want to be mindful of how much of the business that oil and gas upstream activity represents and make sure that we're making a more balanced decision and a more conscious decision this time around. The last time, it was just hey, it's a gold rush, let's go. Nobody said that out loud but was sort of the mind-set. This time around, we're saying, "okay, let's make sure that when we're putting fleet in, it makes sense, both for right here and now and what it means for the business longer term."
Jerry David Revich - VP
Okay. And on that note, I'm wondering if you can just frame the CapEx growth that you folks are laying out here over the balance of the year. Can you just give us a regional flavor, which regions are getting an outsized share of fleet growth, in other words where you folks are seeing the strongest growth?
William B. Plummer - CFO and EVP
It's very broad. I know we say that a lot but that's because it's factual. When you look at it, we're -- maybe it's been a little more jaded to the coast, but because they've been so hot, but it is very broad. It's across the board. The folks in Western Canada are probably getting the least of it for obvious reasons because they had some fleet absorbed. But everybody else is running real strong utilizations and really improvement in their -- throughout P&L and have earned that growth. And that's how we look at it, that you have to earn the growth and then we allocate it. Again, the team's done good job very broadly.
Operator
Our next question comes from the line of Nick Coppola from Thompson Research Group.
Nicholas Andrew Coppola - Senior Equity Analyst
So I wanted to follow up on the NES integration. Now that you're a few months in, it sounds like it's going well and you're on track to hit your synergy targets. Have there been any surprises to the positive or negative? Any color you would add surrounding the integration?
Matthew J. Flannery - COO and EVP
Well, I would say the positive is we have a tendency to lean towards speed when it comes to integration. It's our firm belief that you move that way and you get the benefit of it. I would say this is even faster than we expected. That's what makes it difficult, why Bill had to go through so many assumptions to give you NES stand-alone information. We view that as a very positive story to operating as one company. Another is the time ut improvement. If you looked at slide
[Audio Gap]
you saw that right panel of that slide, you saw that NES came in a little bit heavy on fleet, a little bit lower time utilization. We -- a part of our improvement is that we really ramped up that time utilization by absorbing that fleet quickly as a combined entity. And it just goes to prove that if you get everybody working together quickly, you can take advantage of all the capital that you have as a new combined team, and that was probably even ahead of schedule from what we thought.
Nicholas Andrew Coppola - Senior Equity Analyst
Yes, that's certainly a strong chart there. And then, I guess, just another question, I wanted to ask about there's another slide about Project XL moving more to infrastructure. And can you just maybe add some detail around how you are moving forward with that goal? Are there new equipment types or mix shifts that we should be expecting? Or is it really sort of a sales initiative of reaching out to new contractor types? Maybe if you can just kind of expand on that?
Michael J. Kneeland - CEO, President and Director
Yes, sure, Nick. It really is a focus on that key customer segment, that project type and making sure that we're well positioned to identify the opportunities and that we've got the fleet to support those opportunities when we win them. So it's more than just a new sales initiative, but there's very much a focus that we're bringing to infrastructure projects now that we hadn't in the past. You can see in that XL slide, the impact when you compare us to sort of overall aggregate infrastructure spending in the economy, we're outperforming. So that's the good news, and we want to make sure that we continue to drive that focus because it's a vertical where we think we line up very well with those kinds of projects, those kinds of customers. And we don't believe we were getting our fair share in the infrastructure space previously and so we're driving hard to address that.

Our next question comes from the line of Steven Fisher from UBS.
Steven Fisher - Executive Director and Senior Analyst
As you guys step back and think about the market today, how would you characterize the supply-demand balance for equipment rental? And where do you see that balance headed in the next few quarters as you think about the demand trends versus industry CapEx additions? I mean, would you say that it is actually kind of tight today in some of these markets where you're getting pricing? Or is it just more of kind of your own initiatives? Or are we headed toward a position of kind of a tight market per se?
Matthew J. Flannery - COO and EVP
So Steve, it's Matt. We certainly -- there are certainly initiatives, right? And coming out of the first quarter, just like what we did last year, it's your time to take advantage of what the market can give you as far as your focus on time and rate. So the demand has to be there. But with that being said, we feel that this is not just broad based for us. We expect the industry is doing a better job of being very rigorous on capital management and returns. And I think that we're seeing that play through, and there's no sign that we would expect that to diminish. And everybody that we talk to, whether it's OEMs, whether it's customers, everybody's feeling better about the industry demand and the industry behavior. I guess that's the most fair way to categorize that.
Steven Fisher - Executive Director and Senior Analyst
Okay. And I guess a related question, just thinking about the strong time utilization, really just trying to gauge how much structural change you've made in driving efficiency in fleet utilization. I'm just curious how many points of time utilization do you think you've maybe added over the last year that are a result of better processes and less OEC not available for rent, the time utilization that may be sticky over time?
Matthew J. Flannery - COO and EVP
Yes, I think, it's a great point and it's one of the reasons why we felt good about the NES acquisition because that density of fleet in the market gives you the opportunity to drive higher time utilization. We do think we're enjoying that. And when you think about where the mix of our fleet has come and you look at our year-over-year time utilization, we continue to mix in assets, specifically in specialty that run usually lower time ut and in some instances, significantly lower time ut, yet we keep climbing. So you have to look at it by category to truly break down the advantage, but we're very pleased about the time utilization trend that we've created on a year-over-year basis and how that comps to the industry. And we feel strongly that's due to our density, allows us to do things that maybe a regional or a local player can't do from a time utilization perspective.
Michael J. Kneeland - CEO, President and Director
But thanks for recognizing the fact that we are putting an effort in changing our processes. There's a chart on our investor deck on Page 8 that shows the NES during the time of acquisition where it is today and it speaks volumes about our team stepping up and making sure that we leverage our capabilities to drive better time. Now the question we have to ask ourselves is, is there more for us to pull, and we do believe that. As Matt mentioned earlier, our team has earned it and we want to continue to make sure that we meet that demand. But there's a lot of things that we're working on. And as you pointed out, our processes and lean management is paying some dividends.
Steven Fisher - Executive Director and Senior Analyst
Could that be as much as maybe a couple of points of utilization?
Michael J. Kneeland - CEO, President and Director
It's hard to quantify exactly because there's so many things that we're doing inside the organization.
