Thank you Yvonne and thank you everyone for joining us this morning. 2021 was an exciting year for Solaris. The market continued its recovery and its global oil and gas demand improved significantly and supply remained constrained which supported strengthening commodity prices throughout the year. This led to increased drilling and completion activity and we redeployed systems to meet demand. We also brought two new technologies to market that are now showing evidence of success and we remain committed to paying a dividend to our shareholders. For the fourth quarter of 2021 our fully utilized system count was up 7% sequentially to 63 systems and adjusted EBITDA was up 28% to approximately $10 million. We paid our 13th consecutive dividend and ended the year with $36 million of cash and no debt. During the quarter we ran two of our new Top Fill based systems on jobs that were part of our managed last mile offering. Our Top Fill offerings allow us or our customer to utilize higher payload bottom or belly dump truck trailers while preserving the option to fill our silos using traditional pneumatic trailers for increased flexibility and reliability. During the fourth quarter we were able to use our Top Fill technology to optimize trucking which contributed to improved profit per system. We see this continuing as we roll out additional Top Fill systems. We also continued putting our AutoBlend integrated electric blender through trials. As of today we have four completed AutoBlend units in the field. We're very pleased with how the units are running and are encouraged by the positive feedback from our customers. We continue to see multi-year growth potential with several customers with this new technology. The fourth quarter also saw a full quarter impact of higher pricing that we implemented in August…

Thanks Bill and good morning everyone. I will begin by recapping our fourth quarter results. We generated approximately $46 million of revenue and adjusted EBITDA of about $10 million. We averaged 63 fully utilized systems which represents a 7% sequential increase in the third quarter. Growth in systems exceed our initial expectations due to minimal holiday softness and a ramp of completions activity in December. During the fourth quarter we made a strategic decision to focus on higher profitability last mile work and utilize our new Top Fill technology for our most consistent customers. This change in last mile job mix drove an overall decrease in revenue but an increase in overall profitability in the quarter. Over the course of the quarter we deployed a total of 98 proppant systems which worked with varying degrees of utilization. This was an increase of 10 deployed systems from third quarter levels. Our calculation of 63 fully utilized systems reflects the number of equivalent systems that generated revenue every day in the quarter. Our gross profit margin per system was up 14% sequentially in the fourth quarter. The strong incremental margin increase was driven by a combination of fixed cost absorption, improved last mile profitability, increased mix of 9 and 12 pack configurations, and a full quarter benefit of the price increases we implemented in August. Operating cash flow was approximately $5 million after a net working capital build of approximately $1 million to fund activity growth and accelerated trucking payments, and approximately $3 million for prepayment of long lead items associated with our 2022 growth CAPEX plans. After total capital expenditures of approximately $6 million, free cash flow was approximately negative $1 million in the quarter. Excluding prepayment for 2022 growth plans, free cash flow related to fourth quarter 2021 operating activity…

Yes, thank you. . And today's first question comes from Ian Macpherson with Piper Sandler.

Thanks. Good morning Bill and Kyle, how are you?

Good. Good morning Ian.

So, you are in the enviable spot of selling customer efficiencies in a market that desperately cries out for them right now. Can you speak to any light at the end of the tunnel or lack thereof with respect to the bottlenecks surrounding sands, sand trucking and logistics, do you think that these are enduring bottlenecks that are going to play Solaris’s hands throughout all of this year most likely?

Yeah, they've always been enduring bottlenecks, it's the incremental piece that drives the total and we've seen it as you rapidly added completions crews and lateral lines and sand demand. You caught up with shut down plans from the early days of COVID and they're slowly coming back online. And as those catches up, trucking bottlenecks, it's driver shortage, there's plenty of trucks out there, it's managing drivers. One of the things that surprised us a bit at the end of the year was the fact that we didn't see the slowdown. When you had drivers you kept going. We moved a lot more 9 and 12 pack situations out there for folks preparing for no bottlenecks over the holiday season which was good for us. And we sort of see that that trend continuing of creating a larger buffer just to ensure that you can keep running and don't have to shut down in the middle of the stage or some odd moment in time where you run out of supply. So those all really do play into the hands of reliable systems and ensuring that we can create a buffer and have the reliability needed to make sure that it makes it into the blender.

Okay. When we look at your capital program for this year it's good to see the increased uptake of the Top Fill system and the AutoBlend in particular. I was wondering if you could put a little more detail around the strategic CAPEX, growth CAPEX in terms of what type -- maybe quantity of units that we might expect you to be running on both of these and also what type of accretion we might contemplate relative to the current eco system that we've seen in Q4?

Yeah, the range is really around hedging a little bit on the supply chain and ensuring that we get through these materials and components in the time frame that we expect them to come in, so that is why we see kind of a range. As far as units, we are building multiple of both the blenders and the Top Fills. As far as pay backs or returns we've always targeted returns in line with where we've been on the silo systems as we think about incremental pieces of capital. The really exciting piece of these two new pieces of technology are the ability to pull through new customers and new market share. And so when we look at the returns there that becomes very compelling for us. So, more details to come for sure but we're making these investments because we believe both from the trials over the last 12 months as well as the conversations with customers that there is significant demand for both of these products and they address exactly your first question which is around the tightness throughout the supply chain on sand trucking, etc. Both of these pieces of technology help alleviate some of those bottlenecks and so we feel that there's a really exciting opportunity here to deploy those pieces of kit and we hope that in the future we're building beyond what we got into today but we're going to be very conscious of the uptake in terms of deploying additional capital. I'm very excited about the opportunity there.

Thank you Kyle, thanks Bill.

Thank you and the next question comes from Stephen Gengaro with Stifel.

Thanks, good morning. Two then for me, one I guess was kind of a follow up. When we think about. industry frac fleet demand and we sort of translate that to the demand for your services, how should we think about the changing dynamic with more silos at the well site, I mean is there any sort of step change that you think we should be modeling in as far as demand for your systems over the next year or two, do you think it's somewhat temporarily related to sand shortages, that there's more units per site, how would you guide us to think about that dynamic?

Well I do think that the use of more storage per site is driven by fear of the supply chain but also if you look at the rate, the speed at which the fracking is being done with today's increase, -- will practice longer laterals. If you look at the amount of storage on the well side on a day's use basis like you would conditionally look at storage that's a trend that continues and it continues to drive the need for more storage on site. That said the industry is always trying to save a dime and making sure that they can do it. We provide the insurance and the buffer really is insurance to continue fracking it at those kind of rates. So, I think there is a bit of a step change with it happen right now that will continue. I think on an incremental basis the addition of the Top Fill solution will bring us additional profitability per system driven by ones where we use it ourselves in our last call offering. We also see incremental demand for that system combined with the silos to customers that are not currently using our equipment. So we do see a significant incremental growth with that and that trend we don't see reversing.

Great, that's really helpful. And when we think about, you mentioned price maybe a couple times, price hike last year, and maybe on January 1st, where do you stand on -- can you give us any kind of benchmark for where pricing stands versus from trough levels and/or from peak levels?

I don't know that we'll get into the specifics relative to say 2017 or 2018, a lot has changed, our mix has changed. The last mile piece is an area where that's going to have some significant impact and how that evolves. But I think we showed good partnership with our customers in the downturn and they're showing good partnership with us as activity levels increase here. I think what we've been able to demonstrate for our customers is the continued investment in our systems. going to make to Bill’s prior comment there was, we are making investments to help our customers use our silos more efficiently and that’s around turning trucks more quickly and using the full capacity of the silos on a continual basis. And those are ways where we can make a modest investment but driving significant improvements to our customer’s efficiency in terms of the trucking and use of the silos. And so that on a net basis they may actually be paying less and that's always been our theme in terms of pricing. It is we're trying to find ways for customers to pay less for a fully delivered cost of sand by making strategic investments. And things like the Top Fill also agreed to that story as well.

Great, that's good color. Thanks Kyle. And just one follow up maybe related to that, if we think about incremental EBITDA per fleet per year on a system, I mean at this, given the amount of fleets you have deployed, is that sort of $700,000 range give or take makes sense?

Yeah, I think in the fourth quarter it was probably a little bit higher than that and what we talked about in the prepared remarks is additional scale as well as pricing increase. So, I think we will focus continuing to increase that number up to where it has been historically.

Okay, great. Thank you for the color gentlemen.

Thank you.

Thank you. . And the next question comes from Jon Hunter with Cowen.

Hey, good morning everyone. So the first question is just on the activity front, you said December had kind of a strong exit. You guided up 10% in the first quarter here. I was wondering if you could help me think about how activity is trending so far I guess in the middle of February here, is it up at 10% or are you expecting continued increase through the end of the first quarter?

Yeah, I mean as far as the shaping of the quarter, I think it is evident in kind of what's going on today. There's just a continuing increase in activity throughout the quarter. In January someone said that slow starts just coming out of the holidays and I think as we've seen February shape here we are continuing to see activity go on. And obviously commodity price is helping them.

Yeah, that makes sense. Thanks Kyle. And kind of related to that on the margin front, looking at it on a gross profit per system, do you think you could be bumping up on the 1 million gross profit per system level I guess in the first quarter given some of the price increases you've put through and some of the help you've gotten from mix, any help you can offer there? Thanks.

Yeah, again I don't think we're going to get too far into the details on how that shapes up but we have kind of been clear that we're seeing it continue to improve.

Got it. Then looking at 2022 activity growth, Bill mentioned 30% E&P spending up this year and the returns tracking up 30% plus. How would you expect that to translate into completion activity this year and would you expect Solaris to be able to outperform whatever forecast that is given some of the technology investments you're making?

Yeah, I think if you forecasted 30% activity -- 30% increase in spending that's probably 20% to 25% increase in activity around numbers based on the fact that you're going to get some efficiency gains as well as there's some cost creek to the operator in there. But we also do see us continuing to gain market share through the new offerings. As we said, incrementally we see the Top Fill adding a set of customers that we don't have today and we think that will continue to grow based on the really the addition of our buffer as well as a trucking flexibility really is a unique addition to the industry suite.

Thank you. I'll turn it back.

Thank you. And the next question comes from Sean Mitchell with Daniel Energy Partners.

Hey, good morning guys. Thanks for taking my question. Good to see the growth CAPEX. Obviously there's some demand here for your auto fill -- AutoBlend and Top Fill units. One question for me, in the Top Fill units, is that demand in your I mean just kind of big picture, is that demand really being driven by the simul-frac kind of frenzy, it seems like a lot more folks are talking simul-frac today both public and private? And then the second question will be kind of a follow-on, has your mix in customers changed a little bit over the course of the last year, are you seeing more private companies kind of go to this system than you traditionally have seen?

To your first questions Sean, the private -- the demand for the system and its functionality really is growing and has additional customer tuck take on it. And you can look at it in two places, right, are we adding more well site storage or is it really driven by the volume of sand per truck. And so I think one of the features is we have plenty of unloading capacity through the traditional methods. But if you can increment it up a truck by 10% to 15% and shortage of drivers, you're going to lower your driver need and driver time by moving to the valley drive but I think that’s one of the largest drivers for the what and why of the Top Fill. In terms of the mix, yeah, it always wins but there are more active privates. We're seeing stuff in gas basins, we are seeing stuff in oil basins, it's picked up generally across the board in most basins.

And then Kyle just to follow up, I thought I heard you say the growth CAPEX would be spent in the first half of the year, is that correct?

The guidance that we provided so far is around what we will spend in the first half and the follow-up to that is to the extent we see additional demand which we hope and expect to see. We will come out with more refined second half of the year guidance.

Got it, thank you.

Thank you. And the next question comes from Samantha Hoh with Evercore ISI.

Hey guys, thanks for taking my call. Bill, I guess just to maybe delve into the whole pickup in micro share, I think you guys traditionally have been about one third market share of the frac fleet. Can you maybe talk for us what your target would be by year-end?

We don't look at really our market share, we look at it by customers. And so if we said customer X or customer Y really is trying to take advantage of the usability to have trucks and that's a big driver for what they do. We think those customers will be using the Solaris system as we continue to grow out our Top Fill fleet. So we are going to look at it on a customer by customer basis and think we have targets that will adopt the system as we roll out the additional equipment.

Yeah I think it is the Top Fill but it is also the AutoBlend system as well and Sean you alluded to simul-fracs and reliability of traditional blenders is not great. It is a big challenge on well sites today and what we are seeing in some of our adoption is around reliability of that system but also the -- just the pure capacity from a throughput standpoint as well.

Okay and then just maybe -- just I'm curious about the mix of the 9 and 12 packs. How many of those you guys have like a -- but what is the count right now?

It is still on some 20% of our overall mix I would say. But they did have an impact in the fourth quarter. And really what we're trying to get to there is -- as supply chain gets tighter from a trucking and sand capacity standpoint, our system provides these sort of most efficient way to store high volumes on location. So bolting on an extra 3 and extra 6 pack really can easily provide a little bit of extra storage for customers.

Is the pricing dynamic similar in terms of when you have customers that are going to up to 9 or 12 packs? And then -- I am kind of curious how much visibility you have ?

As far as the traditional sand systems?

Yeah, it is kind of the place where the customers are signing longer term contracts or ?

Yeah, we have one contract today that has a three-year term which effectively is the dedicated provider of storage for that particular customer. And that's gone well for us, we have expanded share with that customer since signing that contract. And as far as our traditional other customers, it continues to be I guess if you will on a spot basis. But as we look at some of the new technologies we are working towards trying to turn up some of that capacity. And then as far as the pricing on the 9 to 12, yeah, I mean it tends to be kind of in line with where we are on traditional systems.

Okay, great, thank you.

Thank you. And we have reached the end of the question-and-answer session. I would now like to turn the call back over to Mr. Bill Zartler for any closing comments.

Thank you Keith. I would like to conclude today by thanking all of our employees in Solaris for their contribution in 2021. I would also like to thank our customers and suppliers for their continued support and efforts throughout last year. We believe we will continue to provide valuable equipment and services to help improve your productivity and without all of you we would not be sharing our positive results today. Thank you all and stay safe and have a great day.

Thank you. The conference has now concluded. Thank you for attending today's presentation. You may now disconnect your lines.
