I will now turn the call over to Justin Jacobs, our Chief Executive Officer.

Justin?.

Thank you, Anna, and good morning, everyone. Welcome to our first quarter 2024 earnings conference call. Thank you for joining us this morning. We appreciate your interest in Natural Gas Services Group. .

I'll start by introducing the team. Joining me on the call this morning is Brian Tucker, our President and Chief Operating Officer; Jim Hazlett, our Chief Technical Officer; and John Bittner, our Interim Chief Financial Officer..

In terms of the agenda for the call, I will start off with some high-level comments on the quarter. After that, John will review the quarter in detail, and then I will finish our prepared remarks with our general industry outlook, our updated guidance and a recap of our growth strategy going forward. We will conclude with a Q&A session..

I'm pleased to report that NGS had another strong quarter. And similar to the last call, we were happy with most areas of our performance. We had sequential growth in rental revenue, rental adjusted gross margin, and rental adjusted gross margin percentage.

The growth in each of these metrics further validates our strategy of focusing new unit growth and high horsepower..

Our first quarter adjusted EBITDA of $16.9 million exceeded our strong fourth quarter figure of $16.3 million. Similarly, our first quarter rental adjusted gross margin percentage of 61.1% eclipsed fourth quarter figure of 60.7%.

The strength in these two metrics, combined with an overall favorable outlook on industry conditions, led us to increase our outlook for 2024 adjusted EBITDA. .

I also want to provide context for our strong growth. Our 2022 adjusted EBITDA was $29.2 million, and our 2023 adjusted EBITDA was $45.6 million. This is a growth rate of 56%. Looking forward to 2024, our outlook range implies a growth rate of 34% to 47%.

These are very attractive growth rates, particularly considering the recurring nature of our revenue, the stability of the revenue as it is largely tied to crude oil production, and our long-term contracts. These organic growth rates are also far in excess of our publicly traded rental compression competitors.

In spite of these higher growth rates, we maintain a lower leverage -- level of leverage at only 2.57x than each of these competitors. .

Putting my public equity investor hat on for a second, these are intriguing figures that I believe our existing shareholders appreciate and our potential shareholders find quite appealing. Considering our opportunities for further growth, I'm quite excited about what NGS can achieve in the coming years. .

With that, I'll turn it over to John Bittner to review the quarter in detail. .

Thank you, Justin, and good morning, everyone. Let me jump right into the review of the first quarter results..

Total revenue for the 3 months ended March 31, 2024 increased to $36.9 million, which was up $10.3 million or 39% from $26.6 million in Q1 2023. Our revenue was up from $36.2 million for the 3 months ended December 31, 2023..

Rental revenue for Q1 2024 was $33.7 million, up from $22.7 million in Q1 2023, for a 48% increase year-over-year, and was up $2.1 million from $31.6 million in Q4 2023, a 7% sequential increase..

Our total adjusted gross margin of $21.1 million in the first quarter increased approximately 90% when compared to $11.1 million in the same period in 2023. Sequentially, total adjusted gross margin dollars increased 4% from $20.3 million last quarter.

Adjusted gross margin as a percent of sales for Q1 2024 was 57.2%, versus 41.8% for Q1 2023 and 55.9% in Q4 2023. This material increase year-over-year in margin percent was driven primarily by rental adjusted gross margins..

Our rental adjusted gross margin dollars increased year-over-year to $20.6 million in Q1 2024 from $11.1 million in Q1 2023, representing an 86% increase. Sequentially, rental adjusted gross margin dollars increased from $19.2 million for a 7% increase.

Our rental adjusted gross margin as a percent of sales for Q1 2024 was 61.1%, versus 48.8% for Q1 2023 and 60.7% in Q4 2023. Our rental adjusted gross margin remained well above recent levels for the second straight quarter..

The incremental margin we've achieved on our newly set large horsepower units is quite high, even more so than we had expected.

The increased revenue generated from these newly set units in Q4 2023 and Q1 2024 has created operating leverage for us, particularly in the areas of field service labor and field service overhead, when compared with the results realized in Q3 2023 and prior..

As we have installed a high number of new units during the last year, the average age of our fleet has gone down, leading to repair and maintenance cost of these new units to be lower than our historical averages.

We do expect these amounts to move in the direction of historical averages for such costs, and we may need to add incremental labor and overhead costs as we continue to grow. These factors generate some caution that levels of rental adjusted gross margin for the past 2 quarters can be maintained in the longer term.

And thus, we expect some downward pressure on these margins over the coming quarters..

SG&A expense for Q1 2024 was $4.7 million or 12.7% of revenue, versus $4.6 million or 17.1% of revenue in Q1 2023. SG&A expense was $4.2 million or 11.6% of revenue in Q4 2023.

Factors leading to the increase in SG&A expense over Q4 include additional head count and associated costs in Q1 2024 and an increase in costs related to professional fees specifically related to public company costs..

Pretax operating income was $9.3 million for Q1 2024, which improved from approximately $400,000 in Q1 2023, and was up sequentially from $4.4 million in Q4. Our net income in Q1 2024 was $5.1 million, compared to $370,000 in Q1 2023 and up $3.4 million from $1.7 million in Q4. .

Earnings per share for Q1 2024 were $0.41 on both a basic and fully diluted basis, compared to $0.03 per share for Q1 2023 and earnings of $0.14 and $0.13, respectively, on a fully -- on a basic and fully diluted basis for Q4 2023..

Our first quarter 2024 adjusted EBITDA was $16.9 million, compared to $7.8 million in Q1 2023, or a 117% increase year-over-year and a 4% sequential increase from $16.3 million in Q4.

Our adjusted EBITDA for the last 2 quarters has benefited from strong rental adjusted gross margin and, to a lesser degree, positive contribution from sales adjusted gross margin. .

At the end of Q1 in both 2024 and 2023, we had 1,245 rental -- utilized rental units. However, in Q1 2024, those 1,245 rented units representing over 444,000 horsepower, compared to just over 335,000 horsepower as of March 31, 2023.

Our total fleet as of March 31, 2024, was 1,894 units, consisting of 542,256 horsepower, ending the quarter with 65.7% utilization on a per unit basis and 81.9% utilization on a horsepower basis. Our average horsepower per unit as of March 31, 2024 was 286-horsepower per unit, up from 277 at year-end 2023..

Turning to the balance sheet. We ended the quarter with $5.2 million in cash and $172 million outstanding on our amended and restated revolving credit facility. In looking at the 2 financial covenants contained in our credit agreement, our leverage ratio was 2.57x, up just slightly from 2.53x as of year-end.

Our fixed charge coverage ratio for Q1 was 3.41x, which was down slightly from 3.57x in Q4. We were comfortably in compliance with both of our financial covenants as of March 31, 2024..

Our accounts receivable balance as of March 31, 2024 was $42.3 million, which remains elevated from normal and expected levels, as discussed on last quarter's earnings call..

During 2023, we experienced a significant number of new units being placed into service, along with price increases on many existing units being implemented during the year. Certain of our systems and processes are undergoing improvement in increased automation to interface to a greater degree and more accurate degree with our customer systems.

All of these issues created delays in us being able to timely collect payments from certain of our customers..

This is more of a timing issue, and there is no concern about our customers' willingness to pay. We feel that we have identified these issues and are remediating them, but completely resolving these issues will take some time.

We are confident that we are making progress and continue to believe that we will have these issues resolved within 2024, and we'll likely see progress in either Q2 or Q3 of this year. .

The net book value of our rental fleet at year-end was approximately $378 million. .

We generated cash flow from operations of $5.6 million in Q1 2024, compared to $18.2 million for Q1 2023. The decrease is primarily related to a usage of cash for accounts payable in Q1 2024 where accounts payable was a source of cash in Q1 2023, offset partially by the growth in accounts receivable as discussed above..

We had capital expenditures of approximately $10.9 million in Q1 2024. This can be broken out to $9.2 million of new unit growth CapEx and rental upgrades, with the remaining $1.8 million being maintenance CapEx. .

We increased the balance outstanding on our amended and restated credit facility by $8 million during Q1..

With that, I will turn it back to Justin for a discussion of the current operating environment. .

Thank you, John. Turning to the overall compression market. Our perspective is positive as it was on the last call. We continue to see significant demand for our rental equipment with attractive pricing and contract tenor.

We see a favorable environment for potential growth in new high-horsepower units over the near to medium term with some customers looking to contract new units as far out as 2026. .

Approximately 75% of our active fleet is located in oil and liquids-oriented basins where activity is primarily driven by crude oil prices. Oil prices remain relatively steady, which should continue to drive activity. Activity and forecasts continue to show stable to increasing production levels for the near to medium term.

We remain reasonably confident in the oil markets for the near term..

The natural gas markets remain relatively weak with reduced production, significant supply, and low prices. While natural gas prices have rallied the last week, we do not currently see natural gas production as a growth story.

While the overall environment can be described as favorable, we remain vigilant that commodity markets can change to the negative in a hurry. As such, our growth plans include an appropriate margin of safety to withstand any potential downturn. .

I'll turn to our 2024 outlook with an update to guidance provided on our fourth quarter earnings call. For a written summary of our outlook, I would point you to our earnings release filed after the market closed yesterday. And I would also remind you of the disclaimer provided at the beginning of this call, which addresses forward-looking guidance. .

Our current outlook for 2024 adjusted EBITDA is $61 million to $67 million. This is an increase from the guidance provided on our last call. We've moved our range up based on the data from 2 quarters of higher rental adjusted gross margin percentage and adjusted EBITDA.

We are very pleased with 2 quarters of rental adjusted gross margin percentage of 61%. This is obviously now a feasible number, but our question is how close we can stay to this level over time. Our guidance does assume some moderation in that number over the course of the year.

We will continue to evaluate the "expected level of margin" as it relates to labor, parts, maintenance costs and overhead levels. .

Further, there is incremental investment that I believe is necessary and return-enhancing as it relates to improving the scalability and efficiency of our operations. In addition to making sure we have the best people, this investment will primarily relate to data and the capture, analysis and use of data in operational decision-making. .

I'll move next to new unit capital expenditures. For 2024, our new unit CapEx expected range remains at $40 million to $50 million. Of that, approximately $15 million is capital to build new units from the 2023 plan that will be completed and installed in 2024.

The balance is 2024 capital plan expenditures that are currently expected to be completed and installed in late 2024 and/or early 2025. We are still in the process of reviewing the capital plans for 2024 and beyond. We are in active discussions to rent new units at attractive prices under long-term contracts.

However, we are only spending capital on new units when we have a contract in hand, and will adjust guidance as dictated by signed contracts. .

We have added outlook for 2024 maintenance capital expenditures. This range is $8 million to $11 million. The majority of this relates to our rental compression units, with smaller amounts for field equipment including trucks and other equipment..

In terms of return on invested capital, our target remains at least 20%. This applies to any growth CapEx, which I would define as new units, unit upgrades and unit conversions. This target is an average rate across our growth CapEx..

number one, optimize the existing utilized fleet; number two, improve our asset utilization through increased utilization of our fleet and conversion of noncash assets into cash; number three, expand the high-horsepower rental fleet; and number four, execute accretive mergers and acquisitions..

On the last call, I described each of these items. For this call, I would like to update progress against each of these parts of the growth strategy. .

The first point is optimizing the existing utilized fleet. There are two current areas of focus. First, we've seen a significant increase in our rental adjusted gross margin percentage.

Simply put, how do we keep as much of that as possible?.

Second, we are raising prices in areas of high cost inflation. Both of these are in process, and we will have more to report in the next quarter. .

The second point of the growth strategy is to improve our asset utilization. In terms of converting noncash assets into cash, two nearing opportunities, inventory and accounts receivable. From the end of Q4 to the end of Q1, our inventory decreased and created $2.65 million of cash. John spoke earlier about accounts receivable.

While it will take a little time for our efforts to be visible in our financials, there is a substantial opportunity to create cash. Between inventory and accounts receivable, I would like to see at least $12 million of cash created by year-end, which is approximately $1 of cash per share.

This created cash will pay down debt and/or create capacity for incremental rental equipment. .

The two other major sources of potential cash conversion are the income tax receivable and our owned real estate. While we believe the opportunity is substantial in both of these, they are likely a little longer lead time. .

The other part of better asset utilization is increasing utilization of our rental fleet. We are in process of completing a full review of our unutilized fleet, which stands at approximately 650 units on the books at the end of Q1.

We believe a substantial number of these units can be upgraded to our smart system, which substantially improves the operational run time for our customers or can be converted to electric drives or high-pressure gas lift units.

These upgrades and conversions will occur over the medium term, but we look forward to reporting progress in the coming quarters..

The third point is the rent -- is expanding the rental fleet. As I mentioned in our outlook, we have maintained our range for new unit CapEx from the last call. It is, however, a great environment to contract high-horsepower units under long-term contracts at attractive pricing.

We are in active discussions with multiple customers, but we'll not spend capital unless units are precontracted. More to come on this in the future. .

Final point is mergers and acquisitions. We are evaluating the landscape of opportunities, but these are early days. I believe we are very well-positioned to complete accretive acquisitions and mergers with our strong growth trajectory but conservative balance sheet. M&A is difficult to predict, so I won't attempt to do so.

I think it is an opportunity, an opportunity that is not necessary for us to be successful at driving shareholder value, but if done properly, namely, it is strategic and accretive, could provide significant incremental value to our shareholders. .

I'm not providing overall goals on each of these items, I'm starting to provide some additional color on potential value creation on each of these parts of the growth strategy. Over the coming quarters, this color and specificity will increase.

I've been in the CEO seat for about 3 months, and I'm happy to report that I'm more optimistic as to our potential than when I started. We certainly have challenges ahead, but the environment is favorable, and we've demonstrated our ability to grow. I look forward to delivering against these opportunities to drive value for our shareholders. .

This concludes our prepared remarks. So I will ask the operator to queue up for the question-and-answer portion of the call. Luke, go ahead, please. .

[Operator Instructions] Our first question comes from Mr. Rob Brown with Lake Street Capital Markets. .

First question, you addressed it quite a bit, but the gross margin sustainability, I think you assumed some, some retrenchment.

But what's the sense of how that normalizes? Are you -- still need to get some data, or do you feel like you'll have a higher level of gross margin with the high horsepower mix increasing?.

So I would say that, after we've seen now 2 quarters of higher levels, we're certainly getting more comfortable that we're going to have a higher level. And we expected with the high horsepower that they would have higher margin, which in fact has been the case. I think over the coming quarters, we'll certainly gather more data.

And our target, our kind of general view is I would say that we've been pleasantly surprised that we are seeing numbers with the 6 on the front of it. We're expecting something more with 5 on the front of it. And that's still our general view as we go forward. But we hope to be able to keep it in the 6s. .

Okay. Great. And then the demand environment, you talked about a fair number of discussions.

Are you still seeing interest -- big interest in the high horsepower and good pricing?.

And then maybe just some color on kind of the demand environment and what it would take to kind of look to, I guess, 2025, '26 capital spending at the current levels. .

So speaking generally of the environment, we're only looking at contracting new units in our high horsepower range, and we are seeing still a strong demand environment in terms of a lack of availability of equipment, in terms of the pricing that we're able to get and in terms of the length of the contracts.

So really, it's quite similar to the last call, we're still seeing quite a favorable environment in terms of demand for high horsepower. .

Okay. Great. And then you touched a little bit on kind of the electric drive conversion.

How much opportunity is there? What's the capital per unit on that? And how is that market looking at this point in terms of demand?.

In terms of looking at the electric conversion, it's still early days for us. As you look at the unutilized portion of our fleet, this is small and medium horsepower. So the average unutilized unit, if you look at our numbers, about 150 horsepower. So this is the small and the medium. .

So the capital cost for conversion there is, on an absolute basis, a relative small dollar per unit. Now the -- if we are successful in converting and getting those placed under contract, the return on invested capital is quite attractive. .

But in terms of opportunity there, it's still too early for us to give any sense of what the magnitude of that could be in terms of converting units and putting them out in the field. .

Congratulations on the progress. .

Our next question comes from Mr. David Locke with Old Mammoth Investments. .

Of the -- about $9 million in year-over-year incremental gross profit dollars that you generated, could you just roughly split that out between how much of that came from the new units that you've put on in the last year and how much of that came from pricing on the existing fleet?.

So I would say that I won't break it out in terms of specific numbers, but just give a sense. The majority of that is going to come from new units. But there is also a substantial contribution, but obviously, less than majority that's coming from price increases. .

Okay.

And how much opportunity is there for pricing in the pre-existing fleet? And to what extent is the lack of availability of new equipment and how expensive new equipment is informing that pricing on your older stuff?.

So I would break it into the high horsepower and then small and medium. In the high horsepower, you can look at our public competitors and see that utilization is exceptionally high. Our story is no different there. And so in terms of the lack of availability, that certainly is informing the price environment. .

In terms of more of our small and medium, even there, it really depends on the basin and what the operator is producing. Is it gas or is it oil? But we're seeing, in certain basins still significant cost inflation. And as a result of that, we, along with others, are necessary for us to increase our prices to maintain margin. .

Okay.

And when you say maintain margin, are you just talking about like daily gross profit dollars or percentage? So that if you get some more revenue, there's more gross profit dollars to the company as well?.

So it is a mix, although we're typically trying to target, maintaining the margin percentage. .

[Operator Instructions] I see no other questions. Mr. Jacobs. .

Okay. Thank you, Luke, and thanks for all of your questions and participation on the call. We sincerely appreciate your support. .

I want to thank all of our employees who delivered these results for shareholders. I also want to thank our customers for trusting us with their business. We look forward to updating you on our progress in the next quarter. Thank you. .

Thank you, everyone. This concludes today's conference call. Again, thank you for attending..
