Thank you, Alicia and Erica, and good morning. Welcome to Natural Gas Services Group's second quarter 2018 earnings review. NGS exhibited a significant increase in total revenues of 24% compared to the sequential quarter, led by our overall sales volumes. Rental revenues were flat, but we see encouraging trends in the real business, that should result in improved revenues going forward. We place more actual horsepower in the field led by our shift into the higher horsepower real compression market and our backlog of contracted rental equipment was significant. Our rental margins were lower due to expenses incurred to prepare equivalent to meet pending rental demand, a necessary current cost to capital future revenues. We continue to see opportunity in future especially in the higher horsepower market. And I'll comment more details to review the financials. Starting with total revenue and look at the year-over-year competitive quarters, our total revenues increased 12% to $16.2 million in the second quarter of 2017 to $18.2 million in the second quarter of this year. Sales increased by $2 million or rental revenues saw a slight increase, but our overall rentals remain fairly flat. For the sequential quarters of Q1 of '18 compared to Q2 of '18 total revenues increased $3.5 million from 14.7 million to 18.2 million. The increase was primarily in our sales component which saw an increase of $3.4 million while rental revenue again remained fairly flat, summarizing, total revenues up in both year-over-year and sequential quarters. Looking at gross margin and comparing the second quarter of 2017 to this current quarter, total gross margin is from $8.1 million to $8 million and was 44% of total revenue compared to 50% of total revenue in the second quarter of 2017. Sequentially, total gross margin increased about 3% from $7.8 million to…

Ladies and gentlemen, at this time we will conduct the question-and-answer session. [Operator Instructions] Our first question comes from Joe Gibney from Capital One. Please state your question.

Just a question on the smaller horsepower price pressure. What tranches specifically are you seeing that as this is very low horse? And then where regionally I guess you are seeing more of that pressure is just broad based?

It's primarily where we have classified is smaller roughly 125 horse and lower and that varies between some of the reciprocating units and the low pressures screw units, but primarily lower pressure, lower volumes screw units. And we’re seeing most of it in matures areas, you get the old Barnett, some of the Central Texas mature stuff, San Juan Basin, things like that. So, it really trends along with what we’re seeing in the overall just dry natural gas market, right? Kind of static pricing, static activity etc. etc. So when you get static activity and somewhat oversupplied market, I would say that’s where we’re getting some of the pricing pressure.

And on the standby rates side, you referenced construction delays somewhat from the higher horsepower units. Is that regionally specific to areas of the Permian or just where exactly is that are you encountering some of those this year on a standby side?

Yes, it’s primarily Permian, and again I want to reiterate it’s just construction delays the rental rates will take place. It’s not -- everybody probably goes on point as to, well, in the bottlenecks or things that we hear about in the Permian, but it’s not that, it’s just some delays in construction. And yes actually that’s good because there’s so much construction going on just taking time to get crudes and get things set up. So -- but those rates will kick in, they contractually bound to kick in. So there’s just not an indefinite delay and yes, it was put in there for instances like this.

And last one for me just on the compressor sales margin. On the quarter, I didn’t catch that and it seems like sales aggregate margins bit all over the place, you referenced just some timing there. Tough to peg just a little help there and then maybe based on compressor sales margin and then how to think about that on a go forward basis?

Yes, let’s say the margin this quarter -- we had total gross margin -- I didn’t -- well hold on -- I must not have given you the compressor sales. Did you want our compressor sales or total sales?

Yes, the compressor sales margin, I think you did 4.7 million in sales just trying to get the margin number on that one?

Yes, the compressor sales margin this quarter was 18% and that’s up from last -- last year, it was 5%, and last quarter 26%. So, you’ve get -- again you get -- the variation as I mentioned I think it's -- we’re averaging higher year-to-date than we did last year, but it’s just up -- and it depends on -- some equipment has got higher-margin and some got lower just kind of depends on the schedule as it goes forward.

Our next question comes from Rob Brown from Lake Street Capital. Proceed with your question.

First on the sales revenue, I think in the past, you talked about a shift away from sales to rental and now it seems that the sales stronger. What’s kind of driving that what are the sizes and what are the market dynamics going on there?

It’s -- our sales have been strong throughout over the last 3 or 4 years, I mentioned in the past kind of contrary to what we’ve been thinking at downturn. And it’s just continued that way, so we have got a couple of pretty good legacy customers just have discontinued the buy through the downturn and actually have started to accelerate repurchases a little. So, yes, we’re just seeing a continuation of what we've experienced the last three or four years. And it’s -- yes, I don't think it's -- well, I’ll say this -- I was going to say, I don’t think it's a permanent fixture although it's been going on for 3 to 4 year, but as a rental, I mean the high horsepower rentals and starting to really get some traction, and certainly we think the other wellhead type or size rentals as we go forward. So, I think we'll get that mix shift back to our traditional ratio between rental and sales but right now it's just been right now is pretty strong has been really for last 2 or 3 years.

And then on the makeready work you did. Is that -- was that in wellhead compression units that are starting to get contraction again? I guess what's going on the wellhead market specifically or is this just shift to high horsepower?

Now, that’s primarily wellhead stuff because all of the high horsepower essentially new. So it’s out on contractor, goes out on contracts, as it’s being built. Well, we have 31% utilization on that so obviously 9 out of 10 are going out right away. But yes, all the makeready is our traditional business and is primarily -- what we saw from 2010 on, the wellhead type gas lift equipment. So we -- that looks like it's picking up pretty, pretty well and we expect that to continue.

Okay and then I guess in the same vein, should we expect additional makeready margin compression for the rest of the year? Is that kind of over at this point?

No, we will continue to see it, and like I say, we -- it’ almost a double edged sword right to you -- you like it, but it does impact current results, but there's a revenue attached to it. So it’s just a typical part of our business since we do expense all those costs, we take those hits currently and don’t capitalize them on the balance sheets. So, we’re taking currently, but again we will see revenue come from the next couple of quarters. But we expect that will continue, now it's hard to say how long it will continue, but I think I probably maybe commented last couple quarters that we can see 4 to 5 quarters of this. But again, once it starts, it keeps rolling as long as things keep growing. We will have those maintenance expenses and this is our biggest quarters so far. But we ought to have corresponding revenue going forward too to take care of them as you go in the future.

Our next question comes from Richard Gurnley with Longfoot Partners. Please state your question.

I'm new to your company and when you were saying, you did 12 overhauls in the second quarter of ‘17 and 31 the first 74 in the second. Then you said, was it $30,000 of makeready cost increased year to year?

No, it was 330,000.

Okay. Now, how does that number compared to the roughly there are 800 basis points of difference in rental margin year to year, which would be about $900,000? What’s -- if the overhaul was 330, is the rest of it some other kind of makeready or…

No, I mean, we highlight that because we always see that coming out, but we also had -- there are couple hundred thousand dollars in increased all expenses year-over-year because as everybody knows, oil has come up. There was some appreciable overtime expenses last quarter due to the extremely hot weather out here in the Permian, a lot of cooling issues on equipment, things like that. So, they all the expenses go into it mainly highlight the makeready because, they are somewhat extraordinary in that and they will take down overtime, but there are good indicator of what we think will be some future activity.

And so, the -- if the makeready was $330,000 and you did 74 units that would of $4,000 or $5,000 a unit?

Yes, 5,000 or 6,000.

That's the right range?

Yes, that's about typically what it will run. And of course those averages vary by quarter ago, but equipments going through there.

And then, the price per -- did you mention -- my phone disconnected in the middle. In the first quarter, you said the price per horsepower was down 5% overall. What is the -- what's the growth number for the second quarter?

It's down 5% Q -- hold on I think Q2 compared to Q1, per horsepower is 1% on per unit. Let me look here. Yes, I saw a 1% decrease in rental rates per unit sequential quarters, yes, that's sequentially.

Our next question comes from Jason Wangler from Imperial Capital. Please state your question.

I wanted to maybe ask a bit about the makeready in a different way maybe, it sounds like obviously you are seeing a lot more units going kind of out in that. I mean is there a number we should kind of think about on a per unit basis? Or anything like that as we think about kind of the expansion of rental fleet from an activity standpoint? Or is that kind of you’ve kind of figured that out as you go out and actually start working on the unit?

Oh, you mean as far as the cost?

Yes.

Yes, it's going to -- it will vary depending on what we got going through, but roughly and very roughly, it’s going to run $5,000 to $6,000 per unit per overhaul. I felt fairly steady but you can have some variation in that.

Sure, but it’s pretty nominal versus even what….

Yes, if you look at our average rental revenue that's 1, 1.5 or 2 months of rental.

And on the CapEx side, I mean you've spent a little bit of money but certainly not very much in the quarter. I mean as you think about kind of that expansion, you kind of give us the CapEx budget, but as you see it seems like there so not be much cash burn going forward really. Is it just a function of as you sees that the markets kind of participate you will kind of participate in kind? Or that’s how you are thinking about the spending levels as you move forward?

Yes, pretty much, I mean we just updated this a little from the point that we see more from coming in from the rental side. And again, all of our capital is new growth capital, so that would portend additional rental equipment going into the fleet and obviously we’re not building much more spec right now, we’re building by fleet rent. So it’s a positive indicator we think going forward. But, yes, if it picks up more next year we’ll update it then. But yes, we’re not -- yes, we’re spending capital money primarily I said 95% on our large horsepower class, which we counted as 400, 600, 1,380 horsepower. So all of the growth capital is going towards the big stuff and like I mentioned, we’ve got 14% of the active fleet now is big horsepower and we’ve got another equivalent amount in work in progress. So, we've got a fair amount of rental CapEx backlog going forward by stretching a least two or three quarters out.

[Operator Instructions] At this time, we’ve no further questions.

Okay, thank you Erica, and thanks everybody for joining on the call, appreciate your time this morning and look forward to visiting you next quarter.
