Thanks, Ariel, and good morning, everyone. Thanks for joining us to discuss Intrepid's third quarter 2021 results. With me on the call today is Intrepid's co-founder, executive chairman, and CEO, Bob Gernobis. Also available to answer questions during the Q&A session following our prepared remarks will be our President, Brian Stone, and our Vice President of Sales and Marketing, Zachary Adams. Please be advised that our remarks today, including answers to your questions, include forward-looking statements as defined by U.S. securities laws. These forward-looking statements are subject to risks and uncertainties that could cause actual results to be materially different from those currently anticipated. These statements are based on the information available to us today, and we assume no obligation to update them. These risks and uncertainties are described in our periodic reports filed with the Securities and Exchange Commission, which are incorporated here by reference. During today's call, we refer to certain non-GAAP financial and operational measures. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures are included in yesterday's press release. Our SEC filings and press releases are available on our website at intrepidpodash.com. I'll now turn the call over to Bob. Thank you, Matt. Good morning to everyone.
Ariel
We recorded third quarter net income of $4 million and adjusted EBITDA of $13.1 million with results benefiting from another strong performance in the sales through our fertilizer segments as increasing prices continue to drive improved bottom line results compared to the prior year. The third quarter is normally our lowest cash flow quarter of the year, and this year was no exception, with $8 million in cash from operations, increasing our year-to-date total to nearly $60 million through the first nine months of 2021. Our balance sheet remains in great shape and allows us to execute on the significant opportunities ahead of us in this strong commodity environment. We ended the quarter with $26 million in cash on hand and no debt outstanding on our revolving credit facility. Earnings for our nutrient segments continued to improve over the prior year as price levels increased for both potash and trio. We announced an $80 per ton potash price increase in August and have continued to move our posted pricing up to match rising spot prices during the past few months. Unfortunately, the Carlsbad, New Mexico region received more than double the amount of average rainfall during the latter half of the evaporation season, which not only added fresh water to our ponds that in turn dissolved harvestable potash back to a brine that we need to evaporate before producing potash. but also led to reduced overall evaporation rates. As a result, our HB facility will produce under a shortened initial harvest season this fall and winter, likely ending production in mid-January. To offset the delayed production, we plan to restart our HB production in March and run for a few months during the spring to increase the potash production during the spring season and capture what is likely to be continued strong pricing in the first half of 2020. Our trio segment continues to generate sequential quarter improvements in gross margin due to rising prices and steady demand. We announced a $50 per ton increase to our trio products in August, and similar to our potash segment, we continue to move spot pricing higher to match rising potash prices across the country during the last few months. We continue to see strong demand and have responded by adding an extra shift at our east plant using overtime labor. With low inventories of key products and the potential for strong demand in spring season, we expect to bring contract labor on at our east mine to continue our extra production shift through the spring season and to better supply our customers. This added shift is expected to increase production by 50,000 tons over the next 12 months, and we have the potential to add an additional 50,000 tons depending upon continuing market conditions. Our oilfield solutions revenue increased in the third quarter as oilfield activity and frac volumes increase in step with oil price. As source water refresh rates increase, we are bringing in an increasing amount of third-party water to supplement our JMA water, which has compressed margin percentages in the segment. Our south water rights remain fully committed for the year, We're beginning to bid for jobs for the first half as operators look to secure reliable supply. High refresh rates and frack rates are becoming the standard, and we're beginning to see operators increasingly value reliability from their water providers, which we believe puts us in great position given our history and capabilities in the Delaware Basin. Before wrapping up my comments, I want to recognize our East Mine one more time for being the winner of the National Mining Association's 2020 Sentinel of Safety Award in the large underground non-metal category. This is a testament to the safety culture and the leadership at our New Mexico operations, and we again congratulate every member of our East Mine on such a prestigious award. And now I'll turn the call over to Matt for a view of our financial results and the outlook.
Matt Preston
Thanks, Bob. As Bob noted earlier, rising fertilizer prices and improving oil field revenues continue to drive positive momentum across our business segments during the third quarter, despite the above-average rainfall at our HB mine. The potash segment generated $4.5 million of gross margin in the third quarter, as higher net rely sales prices drove improvements in our bottom line. As Bob noted, exceptionally high rainfall, more than double our average rates in the Carlsbad region, has reduced our production outlook for the current harvest and we recorded a $3.6 million adjustment in the third quarter related to abnormal production costs. The reduced production at HB led to higher costs of goods sold in the quarter compared to prior periods and may lead to increased COGS for the next few quarters. With potash price continuing to trend higher over the past few months, we expect fourth quarter pricing will improve over the third quarter and estimate an average net realized sales price of approximately $495 per ton. Third quarter potash production trailed the prior year primarily due to a later startup at our Wendover facility and lower ore grade at our HB facility. Our TRIO segment saw great results with third quarter margin of $6.8 million compared to the prior year as higher average net realized pricing and consistent cost of goods sold drove the improved profitability. Similar to our potash segment, recent price increases should continue to increase our realized pricing into the fourth quarter and we expect our average net realized sales price per ton to improve to approximately $370 per ton in Q4. Third quarter oilfield solutions revenue increased to $6.7 million as oilfield and frac activity continues to improve alongside commodity pricing. A portion of our revenue increase was due to additional third party water purchases to meet the refresh rates of operators in the area, which contributed to our increased cost of goods sold as a percentage of revenue. Other revenue sources improved compared to both the prior year and the second quarter of 2021 as produced water disposal rates increase along with the oil field activity in the Delaware Basin. We remain in a solid liquidity position and expect cash flow from operations will increase in the coming quarters as higher price fertilizer sales take effect and as we head towards what has the potential to be a great spring fertilizer season. We spent $12.4 million on capital investments through the first nine months of 2021 and now estimate full-year capital investment of between $18 and $23 million. That concludes our prepared remarks for today. Operator, we're ready to take questions.
Operator
Thank you. We will now begin the question and answer session. To join the question queue, you may press star, then 1 on your telephone keypad. You will hear a tone acknowledging your request. If you are using a speakerphone, please pick up your handset before pressing any keys. To withdraw your question, please press star, then 2. We will pause for a moment as callers join the queue. Our first question comes from Joel Jackson of BMO Capital Markets. Please go ahead.
Joel Jackson
Good morning, Bob and team. How are you all?
Bob
Good, Joel. How are you doing?
Joel Jackson
Thanks. I'm going to ask a few questions one by one. Just understanding some of the commentary around potash production in HB. So HB has, I guess, capacity of 175,000 tons. Talking about producing, you produced 70. We produced about 70. Can you give us an idea? What is the push and pull? What should 2022 production, what should the amount of volume you have available in 2022 be versus what you have available in 2021? How much of the impact will we see in Q4, Q1, Q2? As best you can, give us a bit of intelligence on that.
Ariel
You know, it's a great question. So the averages, if you will, don't change. But when you get a late season rain, I think this is the second really big late season rain where we've had more than double the rain at the very end of the season. Potash that's been precipitated out into the pond and was ready to harvest got re-dissolved. So the potash is still in the pond. We just need evaporation, which occurs at a slower rate, obviously, through the winter and going into the spring. So that's why we'll do what's called a double harvest so that we'll go in and capture that potash that got redissolved back into a brine form will now precipitate either through cold weather, through a cold crack, or it will dissolve out through normal evaporation in the second quarter. I don't know if that answers your question. I think so, yeah. The revert to the mean, we always should revert to the mean average. It's just when you get that potash out and when you have a significant rain event, it causes a delay in when you actually get it. So you're going to be light. Go ahead.
Joel Jackson
So you're going to be light sometimes here for Q4 and Q1, but you think you'll be able to make it up and have a lot to sell in the last three quarters of next year. Does that make sense?
spk19
That's clearly the goal. That's clearly the goal because the potash is in the palms.
spk17
Yes. Okay.
Joel Jackson
Um, okay. That's helpful. Um, And, you know, we noticed that, like, you know, the potash price performance that you're guiding to the fourth quarter relatively looks a lot stronger than performance for TRIO and Q4. Is that just an order book question, or can you talk about that a bit?
Ariel
Not sure I understand the question. You mean that TRIO didn't go up percentage-wise?
Joel Jackson
Yeah, like the quarterly increase you're guiding to in potash for the fourth quarter for price. it looks a lot higher than a quarterly increase you're going to per trio in the fourth quarter.
Ariel
I think if you look at the K value that's in the trio and the magnesium and sulfur, you know, there's always a percentage increase. So, you know, the market continues to be strong, and we just continue to walk that market up as we see increasing demand. So we feel very, you know, let's give it all perspective. I mean, where we were two years ago versus where we are a year ago versus where we are today, we're just going to continue to build out that market appropriately.
spk15
We know that I need your advice.
Matt Preston
Yeah, Joel. Hey, this is Matt. And I'll just jump in there. You know, the fill program on potash was obviously very early this year. You know, we just didn't, we didn't commit our Q3 tons on TRIO nearly as early. And so we, caught a lot of that increased pricing in Q3, much more than we did on our potash tons. So that's why you're not seeing as big of a bump from Q3 to Q4. We already captured a lot of that in Q3. As Bob mentioned, when you look at the K value, it all kind of equals out there. But, you know, we did a great job of managing our trio and capturing that ahead of our potash tons.
Joel Jackson
That's helpful. And on the MG value, we've seen, obviously, magnesium prices be on fire in recent months. And do you capture any of that increased value of magnesium or is it just trios with a different beast?
Ariel
I think we do. We've got a chart that we used to put in our IR deck that showed how trio captured all the components. And so we're clearly at a pricing scenario where we're, we're clearly capturing the proportionate piece of the K the mag, and I would say some of the sulfur. So again, That's a chart we used to publish on a regular basis, and it's probably one we should put back on our website.
Joel Jackson
One more question for me. Can you just share in the third quarter what percent of your oil field solution sales came from sales service of third-party product, and then maybe what that looks like in the fourth quarter as well?
Ariel
Yeah, the one thing I would suggest on third-party water is we have very little margin on that water. So I wouldn't be looking for it. We make a nice margin on it, but there's not a significant margin on that third-party water. So I don't know if I'm answering your question. Obviously, your cogs go up, but you recover it when you sell that water. It enables you to take on some of the bigger fracts. and provide reliability. I mean, if we look at the refresh rates, the frack rates, four years ago, those were 25 to 50,000 barrels a day. And now they're in excess of 250 to 350,000 barrels a day. So you've got to be able to amalgamate, you know, significant pieces of source water through our infrastructure itself and then service those fracks.
Joel Jackson
I guess it's just trying to figure out into 2022, you know, in trying to model a business, the segment, you know, what percent of the sales you think will be third-party at lower margin, what you think will be normal sales at the higher margin?
Ariel
Well, 2021, we're going to be sold out of our JMA water book, and 2022 is looking, given oil pricing, like it's going to have similar structure. I mean, we're negotiating with numerous operators. I I don't see a situation where the 2022 water book doesn't get sold out.
spk10
Thank you very much.
Operator
Our next question comes from Vincent Andrews of Morgan Stanley. Please go ahead.
Vincent Andrews
Hey, guys. This is Will paying on for Vincent. Thanks for taking my question.
Vincent
I was wondering if you could clarify your comments on the 50,000 tons of incremental production from the additional shift at your east mine. Does that mean your east mine is now running at annual productive capacity of 450,000 tons? And then at what rate can we expect that additional production to begin flowing through your sales volumes?
Ariel
Well, we started adding almost 1,000 tons a week. back in September, and so that 50,000 tons should easily flow through in the next 12 months. It's really a function. We've started trying to hire another crew. So in terms of overall operational capacity, that mine's design capacity is about 450,000 tons. So if we add right now, I want to say we're producing between 200,000 and 250,000. That's right. And so an additional 50 takes you up to 350. Above that takes you up to 350. So it really is. I'd say right now your constraint is the labor market in Carlsbad, given the oil field activity, is pretty darn tight. So we're using a combination of overtime and contract workers to achieve that. I don't know if that answers your question or not.
spk05
Yeah, no, that's helpful.
Vincent
And then you also noted that you had the optionality to add another 50,000 tons as well pending like continuing market improvement. I mean, how much does the market have to improve from here in order for you guys to act on adding that addition? I'm guessing it's another shift there.
Ariel
Well, it's really twofold. So, as long as the market stays strong and you generate a good solid positive margin, which we're doing today, you're willing to add additional staff at, unfortunately, a higher cost. So we're all feeling the effects of labor inflation. So as long as that margin stays strong, you're willing to add those laborers on to produce those tons. So you've got to pay attention to your margin availability so that you don't overstaff or do it at the wrong time. I hope that answers your question. Yeah, that's helpful. Thank you for taking my question. So I want to make it clear, the ore's there, the mining equipment's there, the processing capacity's there, everything is there. We just have to bring on the staff.
spk11
Thank you.
Operator
Once again, if you have a question, please press star, then one. Our next question comes from John Roberts of UBS. Please go ahead.
John Roberts
Thank you. Does the rain impact the HB byproduct water availability for the oilfield sales?
spk04
No, not in the least.
John Roberts
Okay. And then what's the outlook for new water leasing activity?
Ariel
Well, you know, we recently – gained preliminary authorization of a significant water well we drilled down at our Intrepid South Ranch that proved up, I want to say it was 1,900 acre feet. So we're going through the final approval process there. We won the administrative hearing against the protesters. We continue to drill wells up in our Caprock well field to supplement our existing water rights. We're very fortunate in that Judge Wexler was overturned in the appellate court on a certain ruling, and he's asked Intrepid and the Protestants to go back and re-brief. So that's a bit of good news as it relates to the Pecos Water case, is that the judge is revisiting his ruling in light of an appellate decision by Judge Bustamante called the Gray case. It's pretty rare that you see a judge go back out and, before he issues an order, request that all the parties re-brief the issue. So we're looking forward to the potential for a reversal there before we have to go through the appeals process. But I think we've got plenty of water. And as we bring on recycling, there's just a lot more there to add that's very environmentally friendly.
John Roberts
And then are you experiencing any logistic issues in either the fertilizer or oil field side?
Ariel
Nothing major. I'd say our truck markets are, are, you know, certainly not, not as impacted. Um, Zach, are we seeing any rail issues other than higher rates?
spk13
No, I think, I think rail movement's been good so far. So, so no issues there. There's a, you know, truck availability during the fall season is always limited just due to harvest and stuff. But, uh, but nothing major on our side at this point.
Ariel
Yeah, I'd say our biggest issue is we've had the opportunity to sell some TRIO internationally, but international freight rates have gotten so high that it doesn't make those sales realistic. But the market's out there and they're pinging us on a weekly basis.
spk10
Thank you.
Operator
This concludes the question and answer session. I would like to turn the conference back over to Bob Journavis for any closing remarks.
Ariel
Just want to thank everyone for their interest in Intrepid, and we really appreciate your time this morning. Everybody have a great day. Thank you.
Operator
This concludes today's conference call. You may disconnect your lines. Thank you for participating, and have a pleasant day.

spk17
Yes. Okay.

Um, okay. That's helpful. Um, And, you know, we noticed that, like, you know, the potash price performance that you're guiding to the fourth quarter relatively looks a lot stronger than performance, excuse me, for TRIO and Q4. Is that just an order book question, or can you talk about that a bit?

Joel Jackson
Yeah, like the quarterly increase you're guiding to in potash for the fourth quarter for price? it looks a lot higher than a quarterly increase you're going to per trio in the fourth quarter.

I mean, if we look at the refresh rates, the frack rates, four years ago, those were 25 to 50,000 barrels a day. And now they're in excess of 250 to 350,000 barrels a day. So you've got to be able to amalgamate, you know, significant pieces of source water through our infrastructure itself and then service those fracks.

I guess it's just trying to figure out into 2022, you know, in trying to model a business, the segment, you know, what percent of the sales you think will be third party at lower margin, what you think will be normal sales at the higher margin?
Ariel
Well, 2021, we're going to be sold out of our JMA water book, and 2022 is looking, given oil pricing, like it's going to have similar structure. I mean, we're negotiating with numerous operators. I I don't see a situation where the 2022 water book doesn't get sold out.

Our next question comes from Vincent Andrews of Morgan Stanley. Please go ahead.
Vincent Andrews
Hey, guys. This is Will paying on for Vincent. Thanks for taking my question.
Vincent
I was wondering if you could clarify your comments on the 50,000 tons of incremental production from the additional shift at your east mine. Does that mean your east mine is now running at annual productive capacity of 450,000 tons? And then, at what rate can we expect that additional production to begin flowing through your sales volumes?
Ariel
Well, we started adding almost 1,000 tons a week. back in September, and so that 50,000 tons should easily flow through in the next 12 months. It's really a function. We've started trying to hire another crew. So in terms of overall operational capacity, that mine's design capacity is about 450,000 tons. So if we add right now, I want to say we're producing between 200,000 and 250,000. That's right. And so an additional 50 takes you up to 350. Above that takes you up to 350. So it really is. I'd say right now your constraint is the labor market in Carlsbad, given the oil field activity, is pretty darn tight. So we're using a combination of overtime and contract workers to achieve that. I don't know if that answers your question or not.
spk05
Yeah, no, that's helpful.
Vincent
And then you also noted that you had the optionality to add another 50,000 tons as well, pending like continuing market improvement. I mean, how much does the market have to improve from here in order for you guys to act on adding that addition? I'm guessing it's another shift there.
Ariel
Well, it's really twofold. So as long as the market stays strong and you generate a good, solid, positive margin, which we're doing today, you're willing to add additional staff at, unfortunately, a higher cost. So we're all feeling the effects of labor inflation. So as long as that margin stays strong, you're willing to add those laborers on to produce those tons. So you've got to pay attention to your margin availability so that you don't overstaff or do it at the wrong time. I hope that answers your question. Yeah, that's helpful. Thank you for taking my question. So I want to make it clear, the ore's there, the mining equipment's there, the processing capacity's there, everything is there. We just have to bring on the staff.

Thank you.

Once again, if you have a question, please press star, then one. Our next question comes from John Roberts of UBS. Please go ahead.
John Roberts
Thank you. Does the rain impact the HB byproduct water availability for the oilfield sales?
spk04
No, not in the least.
John Roberts
OK. And then what's the outlook for new water leasing activity?
spk04
Well, we recently
Ariel
gained preliminary authorization of a significant water well we drilled down at our Intrepid South Ranch that proved up, I want to say it was 1,900 acre feet. So we're going through the final approval process there. We won the administrative hearing against the protesters. We continue to drill wells up in our Caprock well field to supplement our existing water rights. We're very fortunate in that Judge Wexler was overturned in the appellate court on a certain ruling and he's asked, he's asked Intrepid and the Protestants to go back and rebreeze. So that's a bit of good news as it relates to the Pecos Water case is that the judge is revisiting his ruling in light of an appellate decision by Judge Bustamante called the Gray case. It's pretty rare that you see a judge go back out and, before he issues an order, request that all the parties re-brief the issue. So we're looking forward to the potential for a reversal there before we have to go through the appeals process. But I think we've got plenty of water. And as we bring on recycling, there's just a lot more there to add that's very environmentally friendly.
John Roberts
And then are you experiencing any logistic issues in either the fertilizer or oil field side?
Ariel
Nothing major. I'd say our truck markets are, are, you know, certainly not, not as impacted. Um, Zach, are we seeing any rail issues other than higher rates?
spk13
No, I think, I think rail movement's been good so far. So, so no issues there. There's a, you know, truck availability during the fall season is always limited just due to harvest and stuff. But, uh, but nothing major on our side at this point.
Ariel
Yeah, I'd say our biggest issue is we've had the opportunity to sell some TRIO internationally, but international freight rates have gotten so high that it doesn't make those sales realistic. But the market's out there and they're pinging us on a weekly basis.
spk10
Thank you.

This concludes the question and answer session. I would like to turn the conference back over to Bob Jornavis for any closing remarks.
Ariel
Just want to thank everyone for their interest in Intrepid, and we really appreciate your time this morning. Everybody have a great day. Thank you.
Operator
This concludes today's conference call. You may disconnect your lines. Thank you for participating, and have a pleasant day.
