Rhea-AI Filing Summary

Montauk Renewables reported flat 2025 revenue but sharply lower profit. Total operating revenues were $176.4 million, roughly unchanged from $175.7 million in 2024. Net income fell to $1.7 million from $9.7 million, as operating income dropped to $0.9 million from $16.1 million.

Lower average realized RIN pricing, down 29.0% to $2.33, pressured results despite RNG production of 5.6 million MMBtu and a 20.5% increase in RINs sold to 44.1 million. Non‑GAAP Adjusted EBITDA declined to $35.6 million from $42.6 million.

Operating and maintenance expenses rose to $77.6 million and capital expenditures more than doubled to $116.5 million, contributing to cash and cash equivalents falling to $23.8 million from $45.6 million. Long‑term debt, less current portion, increased to $126.0 million from $43.8 million. For 2026, the company guides RNG revenues to $175–$190 million and Renewable Electricity revenues to $35–$41 million, supported by the Montauk Ag Renewables project.

Positive

  • None.

Negative

  • Profit and cash flow pressure with higher leverage – 2025 net income dropped to $1.7 million from $9.7 million and Adjusted EBITDA declined to $35.6 million from $42.6 million, while long-term debt rose to $126.0 million and capital expenditures increased to $116.5 million, compressing cash balances.

Insights

Profit compressed sharply as pricing fell and spending surged.

Montauk Renewables kept 2025 revenue essentially flat at $176.4M, but profitability deteriorated. Net income dropped to $1.7M from $9.7M, while Adjusted EBITDA fell to $35.6M from $42.6M as lower RIN prices hit margins.

The average realized RIN price declined about 29%, outweighing a 20.5% increase in RIN volumes and stable RNG production of 5.6 million MMBtu. At the same time, operating and maintenance expenses rose to $77.6M, and capital expenditures expanded to $116.5M, funding growth projects and new assets.

Leverage increased meaningfully: long‑term debt, less current portion, reached $126.0M versus $43.8M, while cash and cash equivalents fell to $23.8M. 2026 guidance for RNG revenues of $175–$190M and Renewable Electricity revenues of $35–$41M ties to the Montauk Ag Renewables project’s expected commercial operations in 2026, so execution on that facility and realized pricing will be central to future results.

Exhibit 99.1

Montauk Renewables Announces Full Year 2025 Results

 

PITTSBURGH, PENNSYLVANIA – March 11, 2026—Montauk Renewables, Inc. (“Montauk” or “the Company”) (NASDAQ: MNTK), a renewable energy company specializing in the management, recovery, and conversion of biogas into renewable natural gas (“RNG”), today announced financial results for the year ended December 31, 2025.

 

Full Year Highlights:

 

• Revenues of $176.4 million, flat year over year

 

• Net Income of $1.7 million, decreased 82.0% year over year

 

• Non-GAAP Adjusted EBITDA of $35.6 million, decreased 16.5% year over year

 

• RNG production of 5.6 million MMBtu, increased 1.0% year over year

 

• RINs sold of 44.1 million, increased 7.5 million or 20.5% year over year

 

 

We reported an increase in the total volume of RINs sold in 2025 of 20.5% when compared to 2024 and we reported an increase in RNG production in 2025 of 1.0% over 2024 when considering the 2024 fourth quarter sale of an RNG facility. These increases were offset by a 29.0% decrease in average RIN pricing in 2025 when compared to 2024. In connection to our joint venture, GreenWave Energy Partners, LLC, we began matching available RNG volumes to dispensing opportunities through GreenWave's transportation pathways. As a result, we have recorded investment income from the joint venture in 2025 of $1.5 million from the 706 thousand RINs separated by GreenWave distributed to us. In March 2026, we successfully negotiated a five-year gas rights extension at our Raeger facility.

 

In September 2025, a joint motion was filed with the North Carolina Utilities Commission ("NCUC") by various entities seeking to modify and delay certain aspects of the Clean Energy Portfolio Standards, specifically, the portfolio standards relating to swine RECs. In October 2025, we filed response comments to the joint motion with the NCUC requesting they grant modifications or delays only to individual power supplies that have demonstrated need, require power suppliers that have not achieved 100% compliance in 2025 to apply any cumulatively acquired swine RECs to the suppliers unsatisfied 2025 pro rata obligation, and modify the swine REC set-aside for 2026 and beyond to match the requirement originally set by North Carolina in 2018. In January 2026, the NCUC denied the request for waivers and determined that parties must use banked RECs to meet 2025 compliance targets with the ability to use solar RECs to fill any compliance shortage. The compliance obligations for those utilities filing the September 2025 joint motion continue to increase through 2029. We have begun to commission the facility and expect our production and revenue generation activities to commence in April 2026.

 

Full Year Financial Results

 

Total revenues in 2025 were $176.4 million, flat compared to $175.7 million in 2024. Our average realized RIN price in 2025 was $2.33 which decreased approximately 29.0% compared to $3.28 in 2024. Natural gas index pricing increased approximately 51.1% during 2025 compared to 2024. Operating and maintenance expenses for our RNG facilities were $59.1 million, an increase of $5.7 million (10.7%) compared to $53.4 million in 2024. The primary drivers of this increase were increased utility expense, preventative maintenance, wellfield operational enhancement programs, media change outs and disposal costs at our Apex, Atascocita, Rumpke, and Raeger facilities. We also reported within operating and maintenance expenses the costs related to the RINs distributed to us from GreenWave and the costs related to pathway dispensing associated with our dispensing RNG in exclusive unique and proprietary pathways. Our Renewable Electricity Generation operating and maintenance expenses in 2025 were $14.7 million, an increase of $2.0 million (15.3%) compared to $12.7 million in 2024, primarily driven by non-capitalizable expenses at our Montauk Ag Renewables project.. Total general and administrative expenses were $31.7 million in 2025, a decrease of $4.6 million (12.5%) compared to $36.3 million in 2024. The decrease was primarily related to elevated stock-based compensation expense in 2024 as a result of the accelerated vesting of a terminated employee’s restricted share awards. Operating income in 2025 was $0.9 million, a decrease of $15.2 million (94.7%) compared to $16.1 million in 2024. Net income in 2025 was $1.7 million, a decrease of $8.0 million (82.0%) compared to $9.7 million in 2024.

 

Full Year Operational Results

 

We produced approximately 5.6 million Metric Million British Thermal Units (“MMBtu”) of RNG in 2025, flat compared to 2024. We increased our production when considering our 2024 fourth quarter sale of our Southern facility which produced 85 thousand MMBtu in 2024. Our Rumpke facility produced 218 thousand MMBtu more in

1


2025 compared to 2024 as a result of increased volumes of feedstock gas. Our McCarty facility produced 76 thousand MMBtu less in 2025 compared to 2024 as a result of landfill host wellfield bifurcation and changes to the wellfield collection system. We produced approximately 177 thousand megawatt hours (“MWh”) in Renewable Electricity in 2025, a decrease of 9 thousand MWh compared to 186 thousand MWh produced in 2024. Our Security facility produced approximately 6 thousand MWh less in 2025 compared to 2024 as a result of us ceasing operations in connection with the sale of gas rights back to the landfill host.

 

 

2026 Full Year Outlook

 

• RNG revenues are expected to range between $175 and $190 million

 

• RNG production volumes are expected to range between 5.8 and 6.1 million MMBtu

 

• Renewable Electricity revenues are expected to range between $35 and $41 million

 

• Renewable Electricity production volumes are expected to range between 195 and 207 thousand MWh

 

Renewable Electricity revenues and production guidance increase is driven by the anticipated COD of our Montauk Ag Renewables project in North Carolina.

Use of Non-GAAP Financial Measures

 

This press release and the accompanying tables include references to EBITDA and Adjusted EBITDA, which are Non-GAAP financial measures. We present EBITDA and Adjusted EBITDA 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.

 

In addition, EBITDA and Adjusted EBITDA are financial measurements of performance that management and the board of directors use in their financial and operational decision-making and in the determination of certain compensation programs. EBITDA and Adjusted EBITDA are supplemental performance measures that are not required by or presented in accordance with GAAP. EBITDA and Adjusted EBITDA should not be considered alternatives to net income or any other performance measure derived in accordance with GAAP, or as an alternative to cash flows from operating activities or a measure of our liquidity or profitability.

Safe Harbor Statement

This release contains “forward-looking statements” within the meaning of U.S. federal securities laws that involve substantial risks and uncertainties. All statements other than statements of historical or current fact included in this report are forward-looking statements. Forward-looking statements refer to our current expectations and projections relating to our financial condition, results of operations, plans, objectives, strategies, future performance, and business. Forward-looking statements may include words such as “anticipate,” “assume,” “believe,” “can have,” “contemplate,” “continue,” “strive,” “aim,” “could,” “design,” “due,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “likely,” “may,” “might,” “objective,” “plan,” “predict,” “project,” “potential,” “seek,” “should,” “target,” “will,” “would,” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operational performance or other events. For example, all statements we make relating to our future results of operations, financial condition, expectations and plans, including those related to the Montauk Ag project in North Carolina, the GreenWave joint venture, the Bowerman RNG Facility, the delivery of biogenic carbon dioxide volumes to European Energy, the Emvolon collaboration and pilot project, the Rumpke RNG Relocation project, the Tulsa facility project, the resolution of gas collection issues at the McCarty facility, the delays and cancellations of landfill host wellfield expansion projects, the mitigation of wellfield extraction environmental factors at the Rumpke and Apex facilities, how we may monetize RNG production and weather-related anomalies are forward-looking statements. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that we expect and, therefore, you should not unduly rely on such statements. The risks and uncertainties that could cause those actual results to differ materially from those expressed or implied by these forward-looking statements include but are not limited to: our ability to develop and operate new renewable energy projects, including with livestock farms, and related challenges associated with new projects, such as achieving anticipated levels of energy output on a sustained basis, identifying suitable locations, obtaining and refinancing or otherwise repaying acquisition financing and unexpected delays in construction and development; reduction or elimination of government loans, subsidies and other economic incentives to the renewable energy market, as a result of the current presidential administration and otherwise; the inability to complete strategic development opportunities; widespread manmade, natural and other disasters (including severe weather events), health emergencies, dislocations, geopolitical instabilities or events, domestic protests and other forms of civil unrest, terrorist activities, international hostilities, government shutdowns, political elections, security breaches, cyberattacks or other extraordinary events that impact general economic conditions, financial markets and/or our business and operating results; taxes, tariffs, duties or other assessments on equipment necessary to generate or deliver renewable energy or continued inflation that raise our operating costs and increase the construction costs of our existing or new projects; rising interest rates increase the borrowing costs of indebtedness; the failure to attract and retain qualified personnel or a possible increased reliance on third-party contractors as a result, and the potential unenforceability of non-compete clauses with our employees; the length of development and optimization cycles for new projects, including the design and construction processes for our livestock farm and other renewable energy projects; dependence on third parties for the manufacture of products and services and our landfill operations; the quantity, quality and consistency of our feedstock volumes from both landfill and livestock farm operations; reliance on interconnections with and access to electric utility distribution and transmission facilities and gas transportation pipelines for our Renewable Natural Gas and Renewable Electricity Generation segments; our ability to renew pathway provider sharing arrangements at historical counterparty share percentages; our projects not producing expected levels of output; potential benefits associated with the combustion-based oxygen removal condensate neutralization technology; concentration of revenues from a small number of customers and projects; our outstanding indebtedness, ability to refinance indebtedness at acceptable rates or at all and restrictions under existing and future indebtedness; our ability to extend our fuel supply agreements prior to expiration; our ability to meet milestone requirements under our power purchase agreements; existing regulations and changes to regulations and policies that effect our operations; expected impacts of the Production Tax Credit and other tax credit benefits under the Inflation Reduction Act of 2022; decline in public acceptance and support of renewable energy development and projects; our expectations regarding Environmental Attribute volume requirements and prices and commodity prices; our expectations regarding the period during which we qualify as an emerging growth company under the Jumpstart Our Business Startups Act (“JOBS Act”); our expectations regarding future capital expenditures, including for the maintenance of facilities; our expectations regarding the use of net operating losses before expiration; our expectations regarding more attractive carbon intensity scores by regulatory agencies for our livestock farm projects; market volatility and fluctuations in commodity prices and the market prices of Environmental Attributes and the impact of any related hedging activity; regulatory changes in federal, state and international environmental attribute programs and the need to obtain and maintain regulatory permits, approvals, and consents; profitability of our planned livestock farm projects; sustained demand for renewable energy; potential liabilities from contamination and environmental conditions; potential exposure to costs and liabilities due to extensive environmental, health and safety laws; impacts of climate change, extreme and changing weather patterns and conditions and natural disasters; failure of our information technology and data security systems; increased competition in our markets; ability to keep up with technology innovations; concentrated stock ownership by a few stockholders and related control over the outcome of all matters subject to a stockholder vote; and other risks and uncertainties detailed in the section titled “Risk Factors” in our latest Annual Report on Form 10-K and our other filings with the SEC.

 

We make many of our forward-looking statements based on our operating budgets and forecasts, which are based upon detailed assumptions. While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. All forward-looking statements attributable to us are expressly qualified in their entirety by these cautionary statements as well as others made in our Securities and Exchange Commission filings and public communications. You should evaluate all forward-looking statements made by us in the context of these risks and uncertainties. The forward-looking statements included herein

4


are made only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events, or otherwise, except as required by law.

FAQ

How did Montauk Renewables (MNTK) perform financially in 2025?

Montauk Renewables delivered 2025 operating revenues of $176.4 million, roughly flat year over year. Net income declined to $1.7 million from $9.7 million and Adjusted EBITDA fell to $35.6 million from $42.6 million, reflecting margin pressure and higher operating costs.

What drove the earnings decline for Montauk Renewables (MNTK) in 2025?

Earnings declined mainly because the average realized RIN price fell about 29%, from $3.28 to $2.33. Although RIN volumes rose 20.5% and RNG production held near 5.6 million MMBtu, higher operating and maintenance expenses and increased depreciation further weighed on profitability.

How did Montauk Renewables’ balance sheet change in 2025?

Total assets grew to $435.5 million from $349.0 million, but the capital structure shifted. Long-term debt, less current portion, increased to $126.0 million from $43.8 million, while cash and cash equivalents decreased to $23.8 million from $45.6 million, reflecting heavy capital spending and financing activity.

What were Montauk Renewables’ 2025 cash flows and capital expenditures?

Net cash provided by operating activities was $30.3 million in 2025, down from $43.8 million in 2024. Capital expenditures rose to $116.5 million from $62.3 million, driving a net cash outflow from investing and contributing to a reduction in total cash and restricted cash to $24.2 million.

What production and revenue guidance did Montauk Renewables (MNTK) give for 2026?

For 2026, Montauk expects RNG revenues of $175–$190 million and RNG production of 5.8–6.1 million MMBtu. Renewable Electricity revenues are forecast at $35–$41 million with 195–207 thousand MWh, supported by the anticipated commercial operation of the Montauk Ag Renewables project in North Carolina.

How did Montauk Renewables’ RNG and RIN volumes change in 2025?

RNG production was about 5.6 million MMBtu in 2025, essentially flat versus 2024 when adjusting for a facility sold. RINs sold increased to 44.1 million, up 7.5 million or 20.5%, although significantly lower RIN pricing limited the benefit of this higher volume.

What role did the GreenWave joint venture play in Montauk Renewables’ 2025 results?

Through the GreenWave Energy Partners joint venture, Montauk matched RNG volumes to transportation dispensing pathways. In 2025, it recorded $1.5 million of income from this equity investment, driven by 706 thousand RINs separated by GreenWave and distributed to Montauk during the year.
