Montauk Renewables (NASDAQ:MNTK) Holdings, Inc. is a renewable energy company headquartered in Irving, Texas, specializing in the capture and conversion of landfill gas into clean energy products. The company’s core operations focus on the design, development and operation of landfill gas collection systems that extract methane and other biogases generated by municipal solid waste. Montauk processes this gas into renewable natural gas (RNG) suitable for pipeline injection and also generates electricity for sale to utilities and commercial consumers.

Through its subsidiaries, Montauk provides a suite of environmental and waste‐management services across the United States and Canada. In addition to RNG and power generation, the company offers organic waste disposal, odor control and leachate management under long‐term service agreements with landfill operators and municipal authorities. These integrated solutions help customers meet regulatory requirements, earn renewable energy credits and reduce greenhouse gas emissions by capturing methane that would otherwise enter the atmosphere.

Montauk’s shares began trading on the NASDAQ in 2021 following a business combination, building on a platform of landfill gas projects established in the late 2000s. The company is led by Chairman and Chief Executive Officer David L. Herman, whose management team has expanded Montauk’s footprint through the development of new RNG facilities and strategic partnerships. Looking forward, Montauk continues to pursue growth opportunities in waste‐to‐energy technologies and ancillary environmental services.

Montauk Renewables Q4 2024 Earnings Call Transcript

Key Takeaways

• Despite the EPA’s delay of the 2024 RIN compliance deadline, Montauk sold 100% of its 2024 D3 RINs and has zero exposure to timing or volume waiver uncertainty, noting significant price volatility in Q4 with indices between $2.08 and $3.50.
• Montauk is executing a diversification strategy—through feedstock (PECO dairy expansion, 2026 swine waste project in North Carolina), product (renewable power, biochar) and monetization (biogenic CO₂ sales)—to insulate against attribute-market swings.
• Full-year 2024 financials showed flat revenues of $175.7 million, a 34.9% drop in net income to $9.7 million and an 8.3% decrease in adjusted EBITDA to $42.6 million, driven by RIN sale timing, lower natural gas prices and higher operating costs.
• Key operational milestones include a >70% production increase at the PECO facility, Apex 2 commissioning in Q2 2025, conversion of Tulsa’s reg-to-RNG project and an indefinite delay at Blue Granite pending new interconnection strategies.
• For 2025, Montauk targets RNG volumes of 5.8–6.0 MMMBtu with revenues of $150–170 million, renewable electricity of 364,000 MWh ($17–18 million revenues) and capex of $14–17 million (non-development) plus $100–150 million (development).

Presentation

[Operator]

Good day, everyone, and thank you for participating in today's conference call. I would like to turn the call over to Mr. John Ciroli as he provides some important cautions regarding forward-looking statements and non-GAAP financial measures contained in the earnings materials or made on this call. John, please go ahead.

[John Ciroli, Chief Legal Officer and Secretary at Montauk Renewables]

Thank you, and good day, everyone. Welcome to Montauk Renewables' earnings conference call to review the full year 2024 financial and operating results and developments. I'm John Ciroli, Chief Legal Officer and Secretary at Montauk. We are changing the cadence of our SEC filings and earnings calls, beginning with our full year 2024 earnings to better align our primary Nasdaq and secondary JSE markets.

[John Ciroli, Chief Legal Officer and Secretary at Montauk Renewables]

Joining me today are Sean McClain, Montauk's President and Chief Executive Officer, to discuss market and business developments, and Kevin Van Asdalan, Chief Financial Officer, to discuss our full year 2024 financial and operating results. At this time, I would like to direct your attention to our forward-looking disclosure statement.

[John Ciroli, Chief Legal Officer and Secretary at Montauk Renewables]

During this call, certain comments we make constitute forward-looking statements and, as such, involve a number of assumptions, risks, and uncertainties that could cause the company's actual results or performance to differ materially from those expressed in or implied by such forward-looking statements. These risk factors and uncertainties are further detailed in Montauk Renewables' SEC filings. Our remarks today may also include non-GAAP financial measures.

[John Ciroli, Chief Legal Officer and Secretary at Montauk Renewables]

We present EBITDA and adjusted EBITDA metrics because we believe the measures assist investors in analyzing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. These non-GAAP financial measures are not prepared in accordance with generally accepted accounting principles.

[John Ciroli, Chief Legal Officer and Secretary at Montauk Renewables]

Additional details regarding these non-GAAP financial measures, including reconciliations to the most directly comparable GAAP financial measures, can be found in our slide presentation in our full year 2024 earnings press release issued and filed March 13th, 2025, which is also available on our website at https://irmontaukrenewables.com. After our remarks, we will open the call to questions. We ask that you please keep to one question to accommodate as many questions as possible. With that, I will turn the call over to Sean.

[Sean McClain, President and CEO at Montauk Renewables]

Thank you, John. Good day, everyone, and thank you for joining our call. On March 7th, 2025, the EPA announced its delay of the 2024 RIN compliance deadline for all categories. The EPA has yet to decide on a proposed partial waiver of the 2024 cellulosic biofuel volume requirements or the timing of its decision on this matter since its origination in their December 5th, 2024, EPA announcement. Montauk has sold 100% of its 2024 D3 RINs, and it has zero exposure to the timing and resolution of this issue.

[Sean McClain, President and CEO at Montauk Renewables]

We entered 2024 with approximately 6.8 million 2024-vintage RINs unsold. During the fourth quarter of 2024, the D3 RIN market exhibited measurable price volatility with indices ranging from a high of $3.50 to a low of $2.08 and significantly muted purchasing activity by obligated parties. Though these market conditions contributed to our decision to hold a higher balance of D3 RINs at the end of the year, all 2024 vintage D3 RINs have been subsequently sold as obligated parties re-entered the market during the first quarter of 2025.

[Sean McClain, President and CEO at Montauk Renewables]

The volatility continues to impact the renewable natural gas industry in a variety of ways. Montauk's strategy remains steady: to seek out and invest in projects with quality host businesses that exhibit feedstock growth potential, to diversify our sources of feedstock, our product offerings, and our monetization structures, and to ensure the long-term economic viability of our projects in a wide range of production and pricing scenarios. In 2018, Montauk took its first significant stride towards feedstock diversification through our Pico acquisition.

[Sean McClain, President and CEO at Montauk Renewables]

We continue to leverage that diversification through our Pico digestion capacity increase and feedstock amendment with a high-quality, high-volume dairy agriculture host. Our feedstock diversification strategy is poised to further expand in 2026 with the commissioning of our swine waste to energy project in Turkey, North Carolina. Our North Carolina development initiative not only demonstrates our commitment to feedstock diversification but also our commitment to product diversification.

[Sean McClain, President and CEO at Montauk Renewables]

The majority of our production revenue from this project will be derived from renewable power generation, which, when combined with state-based renewable electricity credits, will meaningfully increase our existing REG business segment. In addition to a rebalancing of power generation in our portfolio, our North Carolina development project increases our revenue from commodity-based products whose market value is not directly influenced by traditional federal or state attribute programs.

[Sean McClain, President and CEO at Montauk Renewables]

The biochar commodity produced by our patented reactor process will help insulate the company from volatility experienced in markets underpinned by federal and state programs such as the Renewable Fuel Standard and California's Low Carbon Fuel Standard. Montauk's commitment to diversification through its product offerings is further illustrated in its previously announced agreement with European Energy North America for sales of biogenic carbon dioxide.

[Sean McClain, President and CEO at Montauk Renewables]

This initiative is being prioritized across our portfolio as the company seeks to extract increased value from its existing projects along the rising demand for and the market price of industrial and food-grade CO2. We believe our historical discipline of seeking out and investing in projects with quality host businesses combined with these diversification initiatives will position Montauk to successfully navigate the continually changing landscape of the renewable natural gas industry.

[Sean McClain, President and CEO at Montauk Renewables]

With its commissioning in 2024, this will be one of our last updates regarding our Pico digestion capacity increase. In 2025, we will receive the third and final increase in feedstock under the amendment to our feedstock agreement, and we expect to make that final payment related to this amendment during 2025. We are pleased to report that the production from our Pico facility during 2024 delivered an increase of over 70% versus 2023.

[Sean McClain, President and CEO at Montauk Renewables]

We anticipate commissioning our second facility at our Apex site during the second quarter of 2025. As previously discussed, throughout 2024, we continue to expect a period where we have excess production capacity while the landfill host increases available feedstock. With our previously announced Blue Granite project during February 2025, we received notice from the interconnection utility of their intention to not accept RNG into their distribution system from any project.

[Sean McClain, President and CEO at Montauk Renewables]

As a result, we have indefinitely delayed COD and corresponding capital spend as we both work with the host landfill and prospective stakeholders to evaluate alternative RNG interconnection strategies, both physical and virtual, as well as alternative commodity production opportunities from traditional RNG production. We are pleased to announce our initiative to convert our Tulsa, Oklahoma renewable electric generation facility project through the design and construction of a renewable natural gas facility.

[Sean McClain, President and CEO at Montauk Renewables]

With a variable inlet capacity design and a corresponding average nameplate capacity of approximately 1,500 MMBTUs a day, this new facility will be designed to beneficially process all of the available and growing inlet gas feedstock from its host landfill. We expect that project capital investment to range between $25 million and $35 million and a targeted commissioning date in the first quarter of 2027.

[Sean McClain, President and CEO at Montauk Renewables]

We have prioritized the first of our biogenic CO2 projects related to our previously announced agreement with European Energy and expect to commission a facility at our Atascocita Cedar project during the second quarter of 2027. We expect to begin monetization of approximately 60,000 metric tons per year of food-grade CO2 in advance of the commencement of our offtake agreements at commodity prices.

[Sean McClain, President and CEO at Montauk Renewables]

We continue to progress with our design and equipment selection and construction plans at our other Houston facilities to meet our requirements with European Energy North America to supply their biogenic CO2. Additionally, we are progressing with our design and construction plans to incorporate food-grade CO2 processing into our Rumpke RNG project with an expected commissioning of Q3 2027 and expected volumes of approximately 50,000 metric tons per year of food-grade CO2.

[Sean McClain, President and CEO at Montauk Renewables]

In December 2024, the state of North Carolina approved a change in laws governing the generation of RECs from swine waste under its renewable energy portfolio standards. For qualifying projects meeting specific eligibility criteria, swine REC generation is enhanced by awarding an additional two enhanced swine credit RECs for each swine REC generated, a ratio of 3/1 for a period of eight years, followed by a ratio of 2/1 for a subsequent six-year period.

[Sean McClain, President and CEO at Montauk Renewables]

The company is in various stages of negotiations with other obligated parties to expand REC sales beyond our previously announced agreement with Duke Energy. We now have over 40 separate farming locations secured under long-term agreements to provide access to waste from no less than 200,000 hog spaces in support of our expected processing needs for the first phase of our Turkey, North Carolina facility commissioning in early 2026. With that, I will turn the call over to Kevin.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Thank you, Sean. I will be discussing our full year 2024 financial and operating results. Please refer to our earnings press release and the supplemental slides that have been posted to our website for additional information. Our profitability is highly dependent on the market price of environmental attributes, including the market price of RINs. As we self-market a significant portion of our RINs, a decision not to commit to transfer available RINs during a period will impact our revenue and operating profit.

[Kevin Van Asdalan, CFO at Montauk Renewables]

At December 31st, 2024, we had 6.8 million RINs available but unsold. We have since entered into commitments to transfer all of these RINs. Additionally, we have entered into commitments to transfer all RINs from 2024 RNG production, which generated RINs in 2025. In total, in 2025, we have transferred approximately 9.9 million RINs from the 2024 compliance year at an average realized price of approximately $2.45.

[Kevin Van Asdalan, CFO at Montauk Renewables]

We have no additional 2024 compliance year RINs remaining to be transferred. We have not entered into commitments to transfer a significant portion of RINs from 2025 RNG production. Total revenues in 2024 were $175.7 million, flat compared to $174.9 million in 2023. There was a decrease in the number of RINs we self-marketed during 2024 due to a decision to not commit 6,822,000 RINs in the fourth quarter of 2024.

[Kevin Van Asdalan, CFO at Montauk Renewables]

The 2024 average realized price of $3, average realized RIN price of $3.28, increased approximately 21% compared to $2.71 in 2023. The natural gas price decreased approximately 17.2% during 2024, moving from $2.74 in 2023 to $2.27 in 2024. Total general and administrative expenses were $36.3 million for 2024, an increase of $1.9 million or 5.5% compared to $34.4 million in 2023.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Employee-related costs, including stock-based compensation, were $23.1 million in 2024, an increase of $3.4 million or 17.1% compared to $19.7 million in 2023. The increase was primarily related to the accelerated vesting of certain restricted share awards as a result of the termination of an employee. Our professional fees decreased approximately $1.6 million or 35.3% in 2024 compared to 2023. Turning to our segment operating metrics, I'll begin by reviewing our renewable natural gas segment.

[Kevin Van Asdalan, CFO at Montauk Renewables]

We produced approximately 5.6 million MMBTU of RNG during 2024, an increase of 0.1 million as compared to 5.5 million in 2023. Wellfield optimization operational enhancements, as well as plant processing equipment improvements, contributed to the increase, notably at our Coastal facility, which produced 111,000 MMBTU more in 2024 compared to 2023. Our Pico facility produced 76,000 MMBTU more in 2024 compared to 2023 as a result of commissioning our dairy digestion expansion project.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Our Galveston facility produced 59,000 MMBTU more in 2024 compared to 2023 as a result of previously disclosed 2023 dry weather conditions impacting gas feedstock availability. Offsetting these improvements were unrelated wellfield quality issues and weather anomalies, which lowered production at our Rumpke facility, producing 159,000 fewer MMBTU in 2024 compared to 2023.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Revenues from the renewable natural gas segment in 2024 were $158 million, an increase of $1.5 million or 1% compared to $156.5 million in 2023. Average commodity pricing for natural gas for 2024 was 17.2% lower than the prior year. During 2024, we self-marketed approximately 36.6 million RINs, representing an 8.3 million decrease or 18.5% compared to 44.9 million in 2023. The decrease was primarily related to market conditions and a decision to not market 6.8 million RINs generated and available for sale in the fourth quarter of 2024.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Average pricing realized on RIN sales during 2024 was $3.28 as compared to $2.71 in 2023, an increase of 21%. This compares to the average D3 RIN index price for 2024 of $3.12, being approximately 18.6% higher than the average D3 RIN index price in 2023 of $2.63. At December 31st, 2024, we had approximately 291,000 MMBTU available for RIN generation and had approximately 6.8 million RINs generated and unsold.

[Kevin Van Asdalan, CFO at Montauk Renewables]

We had approximately 358,000 MMBTU available for RIN generation and approximately 108,000 RINs generated and unsold at December 31st, 2023. We have entered into commitments and transferred all of our RINs and inventory related to our 2024 RNG production. Operating and maintenance expenses for our RNG facilities in 2024 were $53.4 million, an increase of $5.5 million or 11.5% compared to $47.9 million in 2023.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Our Rumpke facility operating and maintenance expenses increased approximately $1.8 million as a result of increased media change-out and gas processing equipment maintenance costs. Our McCarty facility operating and maintenance expenses increased approximately $1.2 million as a result of a wellfield operational enhancement program and increased gas compression system maintenance costs.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Our Pico facility operating and maintenance expenses increased approximately $0.9 million as a result of non-capitalizable costs associated with the digestion capacity increase project, as well as expenses associated with efficiency improvements with the existing digesting capacity. Our Atascocita Cedar facility operating and maintenance expenses increased approximately $0.6 million, primarily driven by increased utility expense.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Our Apex facility operating and maintenance expenses increased approximately $0.3 million, primarily related to increased gas processing equipment maintenance costs. We produced 186,000 MWh in renewable electricity in 2024, a decrease of approximately 8,000 MWh or 4.1% compared to 194,000 MWh in 2023. Our Security facility produced 9,000 MWh less in 2024 compared to 2023 as a result of us ceasing operations in connection with the first quarter of 2024's sale of the gas rights back to the landfill host.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Revenues from renewable electricity facilities in 2024 were $17.8 million, a decrease of $0.6 million or 3.8% compared to $18.4 million in 2023. The decrease was primarily driven by the decrease in our Security facility production volumes. Operating and maintenance expenses for our renewable electricity facilities in 2024 were $12.8 million, an increase of $1.1 million or 8.6% compared to $11.7 million in 2023.

[Kevin Van Asdalan, CFO at Montauk Renewables]

The primary driver of the increase was operating and maintenance expenses related to the Montauk Ag Renewables development project, which increased approximately $1.1 million as a result of non-capitalizable costs. We calculated and recorded impairment losses of $1.6 million for 2024, an increase of $0.7 million or 75.8% compared to $0.9 million for 2023.

[Kevin Van Asdalan, CFO at Montauk Renewables]

The impairment losses in 2024 primarily related to the remaining net value of asset at the Security facility, various RNG equipment that was deemed obsolete for current operations, and REG assets that were impacted under initial startup testing for one of our REG construction work in progress sites. The 2023 impairment losses relate to specifically identified RNG machinery and feedstock processing equipment that were no longer in operational use.

[Kevin Van Asdalan, CFO at Montauk Renewables]

None of the 2024 or 2023 impairments were associated with our expectations for our operations to generate future cash flows from operations. Other expenses in 2024 were $3.9 million, a decrease of $1.4 million or 25.2% compared to $5.3 million in 2023. The decrease was primarily related to proceeds of $1.0 million received from the sale of gas rights ahead of the fuel supply agreement expiration at our Security facility and decreased interest expense of $0.5 million.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Operating profit in 2024 was $16.1 million, a decrease of $7.5 million or 31.8% compared to $23.6 million in 2023. RNG operating profit for 2024 was $56.0 million, a decrease of $3.3 million or 5.5% compared to $59.3 million in 2023. Renewable electricity generation operating loss for 2024 was $2.8 million, an increase of $2.2 million compared to $0.6 million in 2023. Turning to the balance sheet, at December 31st, 2024, $56.0 million was outstanding under our term loan.

[Kevin Van Asdalan, CFO at Montauk Renewables]

As of December 31st, 2024, the company's capacity available for borrowing under the revolving credit facility remained at $117.8 million. As of December 31st, 2024, we generated $43.8 million of cash from operating activities, an increase of 6.7% compared to $41.1 million as of December 31st, 2023. Based on our estimate of the present value of our Pico earn-out obligation, we recorded a decrease of $1.7 million to the liability as of December 31st, 2024. This decrease was recorded through our RNG segment royalty expense.

[Kevin Van Asdalan, CFO at Montauk Renewables]

During 2024, we incurred approximately $62.3 million in capital expenditures, of which $27.8 million was for Montauk Ag Renewables, $12.6 million was for the second Apex facility, and $8.8 million was for the Bowerman RNG project. For 2023, our capital expenditures were $63.1 million, of which $18.6 million was for Montauk Ag Renewables, $13.7 million was for the Pico facility digestion capacity increase, and $13.1 million was for the second Apex RNG facility.

[Kevin Van Asdalan, CFO at Montauk Renewables]

For 2025, we expect our non-development 2025 capital expenditures to range between $14 million and $17 million. Additionally, we currently expect that our existing 2025 development capital expenditures will range between $100 million and $150 million. As of December 31st, 2024, we had cash and cash equivalents of approximately $45.6 million and accounts and other receivables of approximately $8.2 million. We don't believe we have any collectibility issues with our receivables balance.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Adjusted EBITDA for 2024 was $42.6 million, a decrease of $3.9 million or 8.3% compared to $46.5 million for 2023. EBITDA for 2024 was $41 million, a decrease of $4.3 million or 9.5% compared to EBITDA of $45.3 million for 2023. Net income in 2024 was $9.7 million compared to net income of $14.9 million in 2023, a decrease of $5.2 million or 34.9%. On January 26th, 2021, we entered into a loan agreement and secured promissory note, the initial promissory note, with Montauk Holdings Limited, MNK.

[Kevin Van Asdalan, CFO at Montauk Renewables]

MNK is our affiliate, and certain of our Directors are also Directors of MNK. Pursuant to the initial promissory note, we advanced a cash loan of $5 million to MNK for MNK to pay its dividends tax liability arising from the reorganization transactions under the South African Income Tax Act of 1962, as amended. As a result of several amendments, the current principal balance of the loan was $10.7 million.

[Kevin Van Asdalan, CFO at Montauk Renewables]

The due date is December 31st, 2033, and the security interest is 976,000 shares of our common stock held by MNK, as amended the fifth amended promissory note. In December 2021, River Props 47 Proprietary Limited, RP47, entered into an agreement to loan MNK up to ZAR 10 million, the RP47 loan. The current principal balance and accrued interest is ZAR 11.7 million or approximately $0.7 million. There is no collateral pledge for this loan.

[Kevin Van Asdalan, CFO at Montauk Renewables]

This loan became due on December 31st, 2024, the maturity date, when MNK and RP47 did not extend the maturity of the loan agreement. Based on the transaction implementation agreement between us and MNK, we were obligated to repay the RP47 loan on MNK's behalf, subject to MNK confirming that RP47 loan maturity was not extended and MNK did not have sufficient funds to repay the loan. As of December 31st, 2024, we accrued a contingent liability for the repayment of the RP47 loan under the TIA.

[Kevin Van Asdalan, CFO at Montauk Renewables]

On February 2nd, 2025, after the end of our 2024 fiscal year but before our 2024 financial statements were issued, our Board of Directors approved the repayment of the RP47 loan under the TIA, and on March 5th, 2025, we repaid the RP47 loan as required under the TIA. The amount repaid is included in the principal balance of the fifth amended promissory note described above.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Prior to the RP47 loan repayment, we concluded that RP47, a related party of us through RP47's ownership of MNK, was the primary beneficiary of MNK under the variable interest entity model. With modification under the TIA and the subsequent repayment of the RP47 loan, RP47 retained its power over MNK, but no longer held significant benefits in MNK.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Following accounting guidance, we determined that with the amendment under the TIA, substantially all of MNK's activities were conducted on our behalf as MNK's only asset is the 976,000 shares of our common stock held as security for the fifth amended promissory note. MNK's only obligation is its loan to us, and thus we are the primary beneficiary of MNK.

[Kevin Van Asdalan, CFO at Montauk Renewables]

We consolidated MNK as of December 31st, 2024, and the repayment of the RP47 loan prior to the issuance of our 2024 fiscal year financial statements was determined to be a subsequent event. As of December 31st, 2024, we consolidated MNK's current assets approximately $52,000, non-current assets approximately $600,000, current liabilities approximately $600,000, and long-term liabilities approximately $16,000. The fifth amended promissory note became an intercompany loan and was eliminated in consolidation.

[Kevin Van Asdalan, CFO at Montauk Renewables]

MNK's investment of approximately $10.2 million in the company is also eliminated in consolidation. There is no gain or loss on the initial consolidation of MNK as the transaction is a common control transaction. We recorded a non-cash acquisition of treasury stock of approximately $8.3 million related to the consolidation of these 976,000 shares of our common stock, collateralizing the fifth amended promissory note.

[Kevin Van Asdalan, CFO at Montauk Renewables]

MNK remains a separate legal entity with ownership of the 976,000 shares of the company's common stock. Subject to market conditions and our insider trading policy, as MNK is an affiliate of the company, MNK can sell these shares to repay the loan to the company. With that, I'll now turn the call back over to Sean.

[Sean McClain, President and CEO at Montauk Renewables]

Thank you, Kevin. In closing, while we don't provide guidance as to our internal expectations on the market price of environmental attributes, including the market price of D3 RINs, we would like to provide our 2025 outlook. It is important to note that our guidance ranges include internal assumptions that may or may not align with current market trends. Also, our outlook is based on selling RINs up to the quarter after RINs are generated.

[Sean McClain, President and CEO at Montauk Renewables]

We expect our RNG production volumes to range between 5.8 million and 6 million MMBTUs and corresponding RNG revenues to range between $150 million and $170 million. We expect renewable electricity production volumes to range between 178,000 MWh and 186,000 MWh. Corresponding renewable electricity revenues are expected to range between $17 million and $18 million. With that, we will pause for any questions.

[Operator]

Thank you. As a reminder to ask a question, please press star one one on your telephone and wait for your name to be announced. To withdraw your question, press star one one again. One moment for our first question. Our first question will come from the line of Saumya Jain with UBS. Your line is open.

[Saumya Jain, Equity Research Associate at UBS]

Hey, good morning. With your RNG facilities, how are you guys looking at things from the data center side of things? Any opportunities you're seeing on that cloud if there would be, bring some color with that?

[Sean McClain, President and CEO at Montauk Renewables]

I'm sorry, would it be possible for you to repeat that question? It was a little difficult to hear.

[Saumya Jain, Equity Research Associate at UBS]

Yeah. With your RNG facilities, how are you guys looking at things from the data center side? Are you seeing any opportunities on that front that you could highlight?

[Sean McClain, President and CEO at Montauk Renewables]

RNG sales from external businesses such as data centers, cold storage facilities, these opportunities are in constant development with conversations that we have with entities such as data centers, cold storage facilities, high-volume users that are interested in co-locating. We've had conversations on a number of our RNG facilities specifically just because of how quickly you can provide that electricity.

The nuance in looking at those synergies is how you benefit from the renewable electric credits, whether or not that power is still put into the infrastructure of the local utility as opposed to sort of direct supplying those entities that would sort of co-locate geographically to your locations. But it's definitively an area, call it quasi-voluntary compliance, that is an interesting alternative to how we diversify the product sales that we have, especially in light of any pending or recent volatility that you see in the federal and state attribute markets.

Thank you. One moment for our next question. That will come from the line of Matthew Blair with TPH. Your line is open.

[Matthew Blair, Managing Director of Refiners, Chemicals, and Renewable Fuels Research at TPH]

Great. Thanks for taking my question. Good morning, Sean and Kevin. I had a few questions on the 2025 RNG revenue guidance of $150 million-$170 million. I know you don't provide the underlying RIN assumption, but can you tell us, does that revenue guidance assume that all of your RINs will be monetized in 2025? Also, would you expect to still receive a premium to benchmark RIN prices in 2025? The past couple of years, you have been able to monetize your RINs at higher than benchmark prices. Is that a trend that you think will continue?

[Kevin Van Asdalan, CFO at Montauk Renewables]

Thanks, Matthew. In regards to expectations on achieving premiums over the existing D3 index price, I believe we will continue—we expect to continue our historical trend of success with selling RINs at advantageous RIN pricing opportunities. In regards to our forward guidance for 2025 and our expectation associated with when we will transfer and recognize revenues on those RINs, generally, as we commented, our expectations are that we will commit to transfer available RINs up to the next quarter available to be transferred.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Associated with the last handful of quarters, we have provided information and will continue to provide information about the timing of those RINs that we keep in inventory that may or may not correspond to that quarter. Additionally, as we continue to move through 2025, here being the first quarter, though we are understanding and working through the EPA regulatory reform, we do anticipate that that regulatory reform may have an impact on the timing of those RIN sales as well.

[Operator]

Thank you. One moment for our next question. That will come from the line of Tim Moore with Clear Street. Your line is open.

[Tim Moore, Senior Research Analyst and Managing Director at Clear Street]

Thanks. I have a two-part question. They're somewhat related. You had some commentary in November about the landfill operators' delay impact, there's some capacity slowness there. Can you maybe comment on that? I just want to check that I understood maybe your earlier comment and prepared remarks.

[Tim Moore, Senior Research Analyst and Managing Director at Clear Street]

I think you said $2.45 might have been the average RIN price transfer this year. I'm just wondering if that's indicative of the D3 RIN pricing because the EPA website stopped posting that after Inauguration Day. I'm just kind of curious what you've seen on pricing the last few weeks.

[Sean McClain, President and CEO at Montauk Renewables]

Yeah, Tim, I can take both of those. With respect to landfills' delays in projects, we've talked in the past. Landfills historically have been a little more synergistic in their willingness to allow for you to sort of infiltrate their open face areas where they're placing waste. That allows for you to accelerate the volume increases that you would expect from well-filled initiatives, horizontal vertical drillings, anything that would improve the volumetric size of your well-filled collection system.

[Sean McClain, President and CEO at Montauk Renewables]

We do continue to see hesitation on the landfill side due to the challenges that they are communicating that they present with their staff. The intricacies of trying to place waste as their primary business, competing against the delicacy that they need to navigate around collection systems, and the time that they then lose to have to remediate those damages as they're incurred has been something that has been more communicated from them over the last few quarters.

[Sean McClain, President and CEO at Montauk Renewables]

It's not fatal in the sense that the collection infrastructures are committed to be increased not only from an environmental NSPS compliance standpoint, but also from the standpoint that they want the additional gas. They want to see the additional royalties. The timing of it is still at times slowed because they're trying to create a little bit of a better divide between when they are high activity in the open face waste placement and when the collection systems come in and start to pull off of that more recently placed waste.

[Sean McClain, President and CEO at Montauk Renewables]

With respect to pricing, other than the standard disclaimers that we don't opine on what we expect pricing to be, it's difficult to say if that price is indicative of what we'll see in 2025. As we sort of mentioned at the beginning of this call, the EPA has floated the idea of a postponement or an adjustment down of the volume obligations for 2024. They haven't indicated any change to 2025. The way that we look at pricing is more of a function of who we sell to.

[Sean McClain, President and CEO at Montauk Renewables]

The majority of our attributes, we place directly in the hands of obligated parties. Our decision to hold those volumes at the end of 2024 are not a direct reflection of our view of pricing: is it the right time to pull and monetize? It's the purchasing parties that are in the market. We saw a significant reduction in the obligated parties' purchasing activity in the marketplace. As we see that picking up in the first quarter, that's when we monetize the remainder of those 24.

[Sean McClain, President and CEO at Montauk Renewables]

So that's a very roundabout way of explaining that we are more focused on the health of the Renewable Fuel Standard program of selling our attributes into the hands of the parties that need to buy them and retire them, as opposed to sort of factoring them on an interim basis to folks that are willing to purchase them and ultimately sell them to obligated parties, which we believe creates the most disturbing price volatility that you can try to manage through.

[Sean McClain, President and CEO at Montauk Renewables]

It would be difficult at this time to say if 245 or something significantly higher or significantly lower is a good indicator to expect what RIN pricing is going to be for 2025 vintage.

[Operator]

Thank you. One moment for our next question. That will come from the line of Ryan Pfingst with B. Riley. Your line is open.

[Ryan Pfingst, Senior Research Analyst at B. Riley]

Hey, guys. Thanks for taking my question. Can you talk a bit about what you're seeing in the voluntary market in terms of demand and pricing there? Thanks.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Ryan, that is one of the more challenging markets that we're trying to get, I don't know if I want to say reliable or meaningful data from. We're working with our internal capacities. We're working through our external partners. The reliability of getting meaningful voluntary information from volumes that are coming out of the RFS to generate RINs into the voluntary market remains a challenge.

[Kevin Van Asdalan, CFO at Montauk Renewables]

That said, we ourselves have entered into what we refer to internally as fixed price or margin share arrangements that generally thus far have not been placed into the voluntary market. They've been placed into the RFS transportation space, and that's what we've seen through 2024.

[Kevin Van Asdalan, CFO at Montauk Renewables]

We have the flexibility either through offtakes at our sites that are coming up for expiration during 2025, or we believe through those existing margin share arrangements that we have in place from 2024 to further divert away from, if necessary, the transportation space and into the voluntary space as the market so dictates.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Related to that is then your evaluation of what is that price associated to a RIN if you could get those volumes into the transportation space versus the fixed price and/or fixed price plus upper spread that you can share in, as well as term. All of those items are challenged right now under the ongoing EPA deferral of the rulemaking in the 2024 obligation that was announced in December.

[Kevin Van Asdalan, CFO at Montauk Renewables]

The uncertainty, though yet currently unstated, impacts to any change in the already existing 2025 RVO. However, also the EPA missing the initial rulemaking periods for the 2026 RVO.

[Kevin Van Asdalan, CFO at Montauk Renewables]

Ultimately, as Sean said on his last question, that is a long-about way of answering your question of we're seeing activity in the voluntary market, achieving readily reliable data similar to how we can get reliable historical data in the transportation space from a RIN generation continues to make this evaluation of when and for how long and at what price points to offer offtake volumes is something that we continue to evaluate as we move through 2025, noting all those sort of caveats and items that we're weighing as we progress through 2025.

[Sean McClain, President and CEO at Montauk Renewables]

Ryan, the only other thing that I would add to that is our diversification plays feedstock offtake arrangements. They're also done with a high degree of fiscal responsibility. The diversification that we focus on isn't voluntary versus obligated party. It's diversification of commodities versus attributes. When you're selling attribute-based products, the voluntary market does move up and down based on their projections of what they compete against, which is the attribute market.

[Sean McClain, President and CEO at Montauk Renewables]

When you elect to proceed with the voluntary market, we view it as a nice backstop so that there is some sensibility in pricing because it's an alternative. That alternative comes with a different risk profile associated with the creditworthiness. Having an attribute going into the market that can appeal and apply to all refiners of petroleum is a much different credit consequence than us going to, say, the previous question where we're selling directly to a solitary cold storage facility for voluntary compliance or a data center.

[Sean McClain, President and CEO at Montauk Renewables]

There's a lot more that needs to be understood about the survivability and the longevity of that business, how it is structured. Not to say that it can't be done. It is something that when you're being ultra-selective on projects, the natural consequence is you are conservative over some of the more financial aspects of what your offtake looks like and the creditworthiness of those offtakers.

Thank you. As a reminder, if you would like to ask a question, please press star one one. One moment for our next question. That will come from the line of Betty [Zhang] with Scotiabank. Your line is open.

[Betty Zhang, Associate Director of Equity Research at Scotiabank]

Hi, good morning. Thanks for raising my question. I wanted to ask about the 45Z. Would there be any impact to Montauk from this production tax credit?

[Kevin Van Asdalan, CFO at Montauk Renewables]

Betty, thank you. We already receive production tax credits from our electric generation portfolio, notably our Bowerman facility. In regards to the 45Z production tax credit, the new expanded enhanced one, to say that there's going to be benefit, to say that we're not investigating or reviewing that benefit, we currently are in concert with our continued review and evaluation of the previously finalized ITC credit as well.

[Kevin Van Asdalan, CFO at Montauk Renewables]

We continue to evaluate and look through applicability and availability under those various tax credits enhanced or expanded under the IRA Act.

[Operator]

Thank you. I'm showing no further questions in the queue at this time. I would now like to turn the call back over to Sean McClain for any closing remarks.

[Sean McClain, President and CEO at Montauk Renewables]
