Good morning. My name is Jean, and I will be your conference operator for Natural Resource Partners L.P. third quarter 2022 earnings conference call. All lines have been placed on mute to prevent any background noise. After the speaker's remarks, there will be a question-and-answer session. If you would like to ask a question during this time, simply press star followed by one on your telephone keypad. If you would like to withdraw your question, again, press star one. Thank you. Tiffany Sammis, you may begin your conference.
Thank you. Good morning, and welcome to the Natural Resource Partners third quarter 2022 conference call. Today's call is being webcast, and a replay will be available on our website. Joining me today are Craig Nunez, President and Chief Operating Officer, Chris Zolas, Chief Financial Officer, and Kevin Craig, Executive Vice President. Some of our comments today may include forward-looking statements reflecting NRP's views about future events. These matters involve risks and uncertainties that could cause our actual results to materially differ from our forward-looking statements. These risks are discussed in NRP's Form 10-K and other Securities and Exchange Commission filings. We undertake no obligation to revise or update publicly any forward-looking statements for any reason. Our comments today also include Non-GAAP financial measures. Additional details and reconciliations to the most directly comparable GAAP measures are included in our third-quarter press release, which can be found on our website.
I would like to remind everyone that we do not intend to discuss the operations or outlook for any particular lessee or detailed market fundamentals. In addition, I refer you to Ciner Resources public disclosures and commentary for specific questions regarding our soda ash business segment. Now, I would like to turn the call over to Craig Nunez, our President and Chief Operating Officer.
Thank you, Tiffany, and good morning, everyone. NRP generated $83 million of free cash flow in the third quarter and has produced $199 million of free cash flow in the first nine months of the year, resulting in the best start to a year in the history of the partnership. We have seized this opportunity to accelerate our plan to become debt-free and redeem all of our preferred units. Year-to-date through today, we have paid off $319 million of debt, including all of our higher cost public bonds that were due to mature in just over two years. $249 million of this debt has been permanently retired with cash on hand, with the remainder temporarily refinanced under our lower cost five-year revolving credit facility established in August.
Our leverage ratio now stands at 0.6x, down from 4.6x just 16 months ago. We look forward to becoming debt-free as our business continues to generate cash. We have paid out $24 million of common unitholder distributions through the first three quarters, which is a 46% increase over the same period a year ago. We believe it is important to provide meaningful distributions to common unitholders while continuing to delever and de-risk the partnership. Proof of our commitment to this principle is the fact that we have paid common distributions for every quarter in the 20 years since the partnership's public debut, with the exception of one quarter in the depths of the COVID-19 pandemic.
We entered into our second subsurface CO2 sequestration transaction during the third quarter with a lease to a subsidiary of Occidental for 65,000 acres of pore space we control in Southeast Texas. This acreage has the potential to store at least 500 million metric tons of carbon dioxide, and we look forward to the opportunity to benefit from Oxy's capabilities and capital investment. When combined with our Baldwin County, Alabama transaction entered into with Denbury earlier this year, we currently have approximately 140,000 acres and 800 million metric tons of subsurface CO2 capacity under lease. The industry for CO2 capture and sequestration is in the early stages of its development, and the success of sequestration projects will not be known for a number of years.
With that said, we are excited to be at the forefront of this nascent industry and believe that these two projects, along with the approximately 3.3 million acres of additional carbon sequestration rights owned by the partnership, provide us a unique opportunity to benefit from the transitional energy economy without the need for capital investment by NRP. Year-to-date revenue from our mineral rights segment is more than double what we saw last year. Metallurgical coal prices remain strong by historical standards, but are down from record levels earlier in the year. Supply chain disruptions, labor shortages, and years of underinvestment in new coal production capacity continue to undermine producers' ability to bring new production online to meet demand. Additionally, historical prices are pulling lower quality met coal into the thermal market, providing further support to met coal pricing.
For these reasons, we think the supply-demand balance for met coal will remain well supported for the foreseeable future. Thermal coal markets continue to benefit from solid energy demand and constrained growth in thermal coal supplies. Many operators continue to struggle with labor shortages, transportation challenges, and pressure from governments, regulators, activists, and capital providers. These factors are limiting the ability to increase thermal production to meet demand. The war in Ukraine amplifies the tightness in thermal coal markets as boycotts of Russian coal exports are forcing European buyers to source coal from other regions, including the United States. We expect these factors to keep thermal prices elevated relative to historical levels for the foreseeable future. Our investment in Sisecam Wyoming benefited from near record international soda ash prices in the third quarter.
While global soda ash prices have softened recently in response to slowing economic growth and increased soda ash exports from China, Sisecam Wyoming continues to maintain market share and earn attractive netback prices and margins due to its position as one of the world's lowest cost producers. Moderating ocean freight costs are providing an additional benefit for net export pricing, and we believe that Sisecam Wyoming will continue to realize strong margins and cash flow for the foreseeable future. Negotiations for 2023 domestic sales have begun, and we expect domestic prices to increase to levels commensurate with export prices as contracts allow. Therefore, we continue to believe the outlook for Sisecam Wyoming remains favorable given the secular trends of renewable energy, the electrification of the global auto fleet, and urbanization.
The global economy is in a period of transition following the post-COVID-19 recovery, and business forecasting is particularly difficult at this time. Unexpected inflation, the war in Ukraine, slowing economic growth, along with volatile and recently weakening prices for metallurgical coal, soda ash, and thermal coal further complicate the forecasting process. Over the past 12 months, the partnership generated $255 million of free cash flow. We are cautiously optimistic that this run rate will be representative of the partnership's performance going forward over the near and intermediate term. During much of the last eight years, the most significant risk to the partnership's common unit holders was the ability to refinance maturing debt. High debt levels relative to free cash flow and the shunning of companies with exposure to coal by numerous equity and debt investors made sourcing capital for many companies, including NRP, difficult.
We were early to recognize the pending exodus of capital from coal and to announce a long-term plan to de-risk our capital structure. In the seven years since, there were times when we were tempted to deviate from our plan and divert cash to other seemingly more interesting pursuits than paying off debt. We stayed the course and now see light at the end of the tunnel. We have paid off $1.2 billion of debt and have only $189 million remaining. Once our debt is repaid and the $250 million of preferred stock is redeemed, common unit holders will have no competing stakeholder claims on free cash flow generated by the partnership. We remain committed to seeing our long-term strategy to completion and remain confident that this path is the best approach to maximizing long-term common unit holder value.
With that, I'll turn the call over to Chris to cover our financial results.
Thank you, Craig, and good morning, everyone. During the third quarter, we generated $82 million of operating cash flow and $75 million of net income. Before getting into our third quarter business segment results, I'd like to add a little color to the light at the end of the tunnel Craig mentioned earlier. With the new five-year revolving credit facility we executed in the third quarter of 2022, we increased our borrowing capacity from $100 million- $130 million, and now have revolving credit available to us that does not mature until 2027. In addition to providing us with significant liquidity, this new credit facility enabled us to accelerate the full repayment of our 2025 senior notes earlier this week. Moving to our business segment results.
Our mineral rights segment generated $76 million of our operating cash flow and $72 million of our net income in the third quarter. When compared to the prior year quarter, segment free cash flow and net income improved $42 million and $36 million respectively, primarily driven by stronger demand and pricing for metallurgical coal. Metallurgical coal made up 65% of our coal royalty revenues and 40% of our total coal royalty sales volumes during the third quarter of 2022. Moving to our soda ash business segment results. Net income in the third quarter of 2022 was $15 million. This was an $8 million improvement compared to the prior year quarter, primarily as a result of higher international sales prices.
Free cash flow from our soda ash business segment in the third quarter of 2022 improved $10 million as compared to the prior year period due to Sisecam Wyoming reinstating its regular quarterly cash distributions beginning in the fourth quarter of last year. Shifting to our corporate and financing segment. Our corporate and financing segment costs for the third quarter of 2022 decreased $2 million as compared to the prior year quarter, primarily due to lower interest expense because of less debt outstanding. This was partially offset by loss on early extinguishment. During the third quarter of 2022, we retired over $60 million of debt, which helped push our leverage ratio below 1.0x.
In addition to the significant progress we made to de-risk and delever the partnership in the first three quarters of 2022, on October 31st, we fully retired all outstanding 9.125% Senior Notes due 2025 at a redemption price of 102.281%. Utilizing cash on hand and $70 million of borrowings on our new credit facility. This early retirement of our 2025 senior notes will save us $27 million of interest expense next year. After the full pay down of our senior notes, we now have $189 million of debt outstanding, primarily in the form of amortizing private notes that are scheduled to be fully repaid by 2026.
Regarding distributions, in August 2022, the partnership paid a quarterly distribution of $0.75 per common unit and a quarterly cash distribution of $7.5 million to our preferred unit holders. Today, we announced third quarter distributions of $0.75 per common unit and $7.5 million cash to our preferred unit holders to be paid later this month. With that, I'll turn the call back over to the operator for any questions.
At this time, I would like to remind everyone, in order to ask a question, press star one to compile the Q&A roster. Your first question comes from the line of George Berman, Cabot Lodge Securities. Your line is open. Mr. Berman, your line is open.
Can you hear me? Can you hear me?
Yes, sir. We can hear you.
Great. Thanks for taking my call. Congratulations to a very good quarter. I've got one quick question. Could you detail for us the exact terms of the preferred shares and what interest or dividend they're paying on those, and if they're convertible and at what price? Thank you.
Chris?
Sure. I'll take that. Yeah. We do have this disclosure of the terms of our preferred units in our filing. If you wanna see some more detail of the terms of those preferred units, you know, our 10-K or our quarterly filings would be a great place to check in the footnotes. I can tell you, we have a 12% coupon, and there is no maturity date. They are perpetual. You know, they are preferred equity and the liquidation price is 1.85x, which decreases as we continue to pay preferred unit distributions.
As we are continuing to pay preferred unit distributions, that the premium to redeem those units decreases over time.
The redemption price is reduced by the payments you make on those preferreds.
Exactly.
Okay. I have one quick question on Sisecam. I understand that the Turkish majority owner last year tried to acquire the rest of the company. Where do those negotiations stand? Or are you considering selling your position off there 'cause it's a minority position?
This is Craig. I believe you're referring to the fact that Sisecam Resources, which is our partner in Sisecam Wyoming, is attempting to buy out the units that are held by the public of Sisecam Resources that it does not already own. They're trying to take.
Right.
Taking the public entity private. That does not involve the Sisecam Wyoming entity that we own interest in. That's a transaction that's taking place between the various owners of our partner in Sisecam Wyoming, and we're not involved in that in any way.
Okay. There is no worries about you being taken out?
N-no.
Okay, great. Well, good luck for the future. I think we've got a long ways to go with the stock price appreciation after your one-for-ten reverse split, but we're definitely going in the right direction.
Thank you very much for your support and your call.
Your next question comes from the line of Mark Zinn. Your line is open.
Hi. Hi, Craig, and hi, Chris. I'm sorry to ask, but I've just sort of following up. Can you just go over what the decrease of the premium is on the preferred, what the sort of the rate is? Like, where do you wind up, let's say, in 2025? When do you get to par? I apologize for not remembering.
No, sure thing. I'll take this one. Good morning, Mark. Thanks for the call. Right now, the premium is about 20%. You know, one way to look at it, each time we pay a quarterly distribution, that the premium drops about 3% each quarter.
It says 12% per year. If you're at 20%, does that mean that you're at par in 1.75 years?
That sounds about right?
Yes.
Uh-
Yes.
Okay. At some point, maybe you'd even pay the premium, I would think. Is that reasonable or not?
It's possible.
Yeah. Okay. All right. That's great. Again, congratulations. Is there any sense on if you were to look at CO2 sequestration, can you put a dollar number at all on what you would get paid per ton of CO2 sequestered?
We do have provisions in the agreements that we have with our two lessees that specify what our payments would be, but we are under non-disclosure obligations with them. I can frame it for you this way. We did a timber sequestration transaction where we sold credits last year in exchange for sequestering carbon in timber that we owned in Appalachia. We received-
Yeah.
About $13 per metric ton of CO2. Now, that's not a direct comparison of what one would expect to receive for sequestering subsurface. Because in that situation, the timber had already grown over the last multiple decades. It was in place. The buyer of the credits did not have to put any capital at work in order to capture the CO2. With subsurface CO2 sequestration, the parties that would pay us for the use of our pore space will have significant capital expenditures they will have to make. I think so it's gonna be something much less than the market value of the credits that we would receive.
I would suspect that, if you used a couple of dollars a ton, that's probably a good guesstimate at this time, simply because the industry is so new, and that's a relative number.
No, it makes sense. I didn't study the press release, but can you tell me what was it that you got in terms of upfront payments or you expect to get as opposed to?
Well, we're not allowed to. Again, we're not allowed to disclose that because of confidentiality. Now, the reality is in our press release and in our financials, you can go to our mineral rights revenue line breakout, and we did aggregate our carbon neutral initiatives income in the quarter and year to date. You can see that there, but we can't tell you about specific contracts.
Any kind of movement on coal export activity that you would think would lead to an increase in production?
Kevin, you wanna answer that?
Sure. Thanks for the question. We have seen during the quarter the creation of a new lease in the metallurgical space. We're seeing some movement there. Overall, you see the limitations still in place on ramping up production in both met and thermal impacted by labor force access to capital and other. We were successful in signing or modifying a lease in the met space during the quarter.
Okay, good. Thank you. Good to get caught up.
Thanks, Mark. It's good to talk to each quarter.
Thank you.
Again, if you would like to ask a question, press star then the number one on your telephone keypad. There are no further questions at this time. Oh, sorry. Mr. Berman has asked another question. Just a moment.
Hello? Can you hear me?
We hear you now.
Any movement on the oil and gas? I saw you had some oil and gas royalty revenues there. Any of your properties possibly open for possibilities there?
We do have oil and gas royalties, as you can see from our financial statements.
Yep.
They are a small part of our business with higher oil and natural gas prices that we have seen over the last 18 months. There has been increased drilling activity on the acreage that we hold. That is primarily in the Haynesville Shale of North Central Louisiana. Those wells tend to come on at fairly high rates of production, and they quickly drop off. There's no way to tell how much drilling is going to take place and how much new production is going to come on. We have had a pickup in drilling and have had a pickup in cash flows over the course of the last year.
Okay, great. Maybe one last question. Would you contemplate maybe repurchasing some of your common shares?
I'm sorry. Could you repeat that question, please?
Would you consider repurchasing some of the common shares in the market since the preferreds have a 20% premium still on them?
We are, as we've said previously, our long-term plan is to pay down all of the debt, outstanding debt of the partnership and then to pay down our preferreds. We don't intend to pay a premium on the preferreds. When you look at our cash generating capability, it will still be some time before we will have finished paying off the debt and the preferreds. To buy back common units currently, while we still have debt outstanding, would actually cause the leverage ratio of the company to increase, all things being equal, which is not the direction we're trying to go at the moment.
Understood.
But-
Thank you.
You bet. Thanks for your questions.
There are no further questions at this time. Craig Nunez, I'll turn the call back over to you.
Thank you, operator. Thanks everyone for joining us today. Thank you for the questions. Thanks for your support of NRP. We've been traveling a long road here in our de-lever and de-risk strategy, and it looks as though we're coming to the end of the tunnel, as we said earlier. Thank you for being with us, and we look forward to working with you in the future. Have a good day, and talk to you next quarter.
This concludes today's conference call. You may now disconnect.
