Thank you, Alicia and Ross, and good morning. Welcome to Natural Gas Services Group's first quarter 2018 earnings review. NGS' rental revenues continue to solidify this quarter and our rental backlog including all horsepower classes grew dramatically, pertaining further gains in rental revenue. We continue to set our newer, larger horsepower units and see a strong and growing backlog of orders. Our total sales revenues were off this quarter due to variety of factors including lower flare activity, a large non-recurring engine sale in the last quarter and delayed fabrication of some large horsepower compressor sales in favor of large horsepower rentals. But this fabrication delay was as short-term impact in the favor or a longer-term benefit and our sales backlog indicate, those sales are only delayed and should materialize in later quarters this year. We continue to report positive net income, our gross margin remained strong and SG&A decreased throughout the quarter. Importantly, operating cash flow is solid and our cash balance provides sufficient liquidity for fleet expansion. I'll comment in more detail as we review the financials. Our total revenues decreased in sequential quarters primarily due to scheduled compressor sales and about $2 million have been delayed to make way to build some of the larger 1,320 horsepower rental units. I'll detail this later, but looking at the year-over-year comparative quarters, total revenues decreased $4.2 million from $18.9 million in the first quarter of 2017 to $14.7 million in the first quarter this year. For the sequential quarters of the fourth quarter of 2017 compared to the first quarter this year, total revenues were off 12% or $1.9 million, from nearly $16.7 million to a little over $14.7 million. As previously discussed, this decrease is primarily the result of sales pushed out to later quarters. The sales were…

[Operator Instructions] Our first question comes from Joe Gibney from Capital One. Please go ahead, Joe.

Thanks. Steve, how are you doing?

Hi Joe, good.

Just a question on utilization outlook, so your comment certainly indicative of growing backlog of demand here on the rental side, your build at least in terms of fleet count pretty in line with what you'd advertised here on the CapEx front. But bridging into 2Q, just help us gap a little bit from sort of this 50% utilization in April and sort of maybe what you think you could trend over the next couple of quarters, given what sounds like pretty robust demand building particularly on the higher horsepower side?

Well, you know, while we're – this utilization is getting harder and harder to project. While we're fighting, it's a good fight and it's a good problem. As you know the utilization, we – it's growing, because the business looks like it's growing, but we're also adding to the denominator, because we are building a lot of this new equipment. So, while we're increasing the numerator something, the denominator is also increasing. So, as much as we saw in the last recovery in 2010, 2014, the utilization grew at a slower rate than you'd expect just because we're idling the equipment at the same time. So, it's going to be a little slower growth than what if you just took the number of units of horsepower that's being put out and you didn't have any growth in the fleet, but all this new horsepower obviously is new growth. So, that's going to tap down just that growth in utilization somewhat and disconnected a bit, and I think I mentioned this last time, we're going to get a little disconnect between utilization and revenue growth over time. But, we are seeing some growth in the other horsepower ranges that we hadn't seen as much at this point, so the 200 to 300 horsepower gas lift equipment is starting to move a little move. The VRUs is staying very popular. So, from small to large, we are seeing some growth in this side. Now, the big horsepower is the biggest piece – the biggest factor in growth right now and of course obviously the biggest dollars and added to the horsepower. So, [profit] is low on this, because it's hard to say, but that's where we're going to run into. I think we'll see the utilization grow but not as quick as we'll see revenue grow.

Okay. Fair enough. Could you repeat the compressor sales gross margin? Did you say 17% or was it little higher, I understand?

No. I think it's 26% this quarter.

26%, okay. And then on the flare market, I know, it's small little piece, tends to be lumpy, but can be higher margin at time. But you referenced a bit of a down tick there, is that just transitory or something that we should be thinking about moving ahead as element that could continue to drop off?

No, we think it's going to be pretty decent this year. But what we had in the last quarter was just a lot of year end orders come in. People rushing to get this stuff done by fourth quarter and we had a couple of particular bigger orders that they wanted them by end of the quarter. So, the revenue level is still good. We think it's going to stay good, but the comp was kind of rough, just because we had a year-end rush.

Got it. Okay. I appreciate it, Steve, thanks.

Thanks Joe.

Our next question comes from Jason Wangler from Imperial Capital. Please go ahead, Jason.

Hey, Steve, good morning.

Hi, Jason. How are you?

I am doing okay. Hope you are too. I was just wondering all this talk in the Permian specifically, but you're hearing it in DJ and other areas too about, I need to make sure that they can capture their gas and flaring not be an option? Are you hearing more about the ability to move units in or you know gas lift operations of reinjecting things over the last few weeks or so, because it seems like that's something that would be a potential solution for some of these folks, specifically in the Delaware. I know you are building more larger equipment which that may need, but just kind of curious if you are seeing any additional demand coming from that kind of a situation that we are seeing now?

You mean from a reinjection perspective?

Yeah. Just for gas lift operation.

You're talking about reinjection from pressure management standpoint or just reinjection for the gas lift?

Just reinjection from the gas lift, basically it is finding a way to get to not flare or put the gas on the pipe, and since there may not be piped out there?

Yeah. Well, that's the majority of what we are seeing. I mean all these large horsepower, we've started putting out the last two or three quarters is all centralized gas lift. This is what we identified two or three years ago as to when we first starting moving on the 400 to 600 that we were seeing more and more since last gas lift come along. You're still going to have the wellhead gas lift like we've got and we are well positioned for that. But the centralized stuff start coming up too, so all these big horsepower we see going out is centralized gas lift. In addition to what we are starting to see now on this 200 to 300 horsepower smaller units, that was more of the wellhead gas lift stuff, so that is the majority of what we are seeing right now.

Okay. And I guess, like I said, it just seems like with the conversation of basically trying to give the gas away for free if they can in the Delaware specifically that's probably happening in the Midland too. But do you think that that changes any of the demand for them? Or is it simply, just say, if we have a well coming on, we need this equipment and do you have it or do you not? Or do you see that maybe, if they really are giving it away for free, at this point, they just need – your equipment to plus the well flow? Does that change their activity level with you at all? Or is it really just kind of the same thing, twice?

No. I don't think it changes, because you know, in gas lift, since they are not getting anything for that gas, you know they are not selling, they are just recirculating it downhole to lift more oil out. So, you've already got the kind of the zero net revenue from gas, but obviously you make it from the oil lift and oil produced. Now there is a lot of talk about oil pipelines being a potential bottleneck out here. And there is talk about – we haven't seen really too many pinch points from our perspective. But there was an interesting article last day or two about a lot of the West Texas crude, since it has wider differentials to some of the other benchmarks is being shipped from here to the eastern refineries. And they've been shipping them by – pipelines are getting full, they have been shipping them by ship actually, and now they are talking about more rail shipment. So, I think you got to a point to where the difference was attractive for this crude and that can absorb shipping costs to be moved around. So, that tells me, there's not going to be a whole lot of bottlenecks, not any more bottlenecks development. And since we haven't really seen an impact, I mean we're growing in that part of it, I wouldn't expect you to see too much hindering our efforts in that area in the future.

I appreciate the color. Thanks Steve.

Okay. Thanks Jason.

[Operator Instructions] Our next question comes from Robert Brown from Lake Street Capital. Please go ahead, Rob.

Good morning, Steve.

Hi, Rob.

Just I wanted to follow-up on, I think you talked about an $8 million orders in April for the high horsepower, I guess congratulations there. But also what sort of driving that market increase I guess, are you gaining share or are you seeing demand growth? And just more color on that $8 million would be great? Thank you.

Well, it wasn't $8 million, so it was eight of the larger horsepower units for rental. So, it'd just be capitalized money, but we are seeing both. I mean obviously, at least for part of next year or two, anything we get is a share increase, because we're new to the market, so we're taking away from somebody that would have gotten it otherwise. So, until we establish maybe a little more depth in that market which we intend to, everything we are going to get, I'd say over the next couple of years is going to be a share impact. But it's also just the growth at here, there is lot of compression going out here. A lot of it looks to be big stuff. We saw the big horsepower move first, and now we're starting see some of the more medium wellhead type horsepower start to move too. So, I think you can attribute to both. Probably majority is just growth out of here, but anything we get is share from somebody right now.

Okay, good. And are these eight units at sort of similar to your first group, are they good margins? Are the long-term contracts, just help me understand that?

Yeah. Same sort of thing, we are trying to keep pricing in a reasonable realm, which means a little higher than market, and these are multiyear realm contracts.

Okay, good. And then maybe just, like to hear comments on the supply chain, are you seeing availability of engines tightened? And any cost kind of growth going on in the supply chain?

Yes. We are seeing deliveries. The engine and compressor deliveries don't seem to be getting any worse. There is development of bottleneck and gas coolers. We are seeing some of that. What that means is, this is not really impacting our ability to deliver, just mean you got a plan a little quicker out and/or sometimes, you got to put a little longer deliveries than people like. But we're in no different shape than anybody else in that market, [heard about] Boston, the same suppliers. So, there is – you know there is, just had to get a little ahead of the calendar there a bit. From a cost inflation standpoint, yes, all the major components are going up, the compressors, the engines, coolers, sealers are going up a little, everything else. So, you're getting some inflationary cost increases in this market. Some inflation, which are market driven, some are just based on cost of goods, but we are seeing some of that.

Okay, good. Thank you. I'll turn it over.

Okay. Thanks Rob.

[Operator Instructions] And at this time, there appears to be no further questions.

Okay. Thanks Ross. And appreciate everybody joining me on the call and look forward to talking to you next quarter. Thanks.
