Montauk Renewables Announces Second Quarter 2026 Results

(Moderate)
(Neutral)
Tags

Montauk Renewables (NASDAQ: MNTK) reported second quarter 2026 revenues of $54.0 million, up 19.7% year-over-year, driven mainly by environmental attribute revenues from RINs sold, including distributions from the GreenWave joint venture. Net income was $0.2 million versus a $5.5 million loss a year ago, while non-GAAP Adjusted EBITDA rose 144.5% to $12.3 million.

RNG production increased 3% to 1.5 million MMBtu and Renewable Electricity output rose to 44 thousand MWh. Montauk began generating power at its Turkey, North Carolina facility in July 2026 and continued ramping feedstock collection toward 400–450 thousand hog spaces. Full-year 2026 RNG revenue and volume guidance was reaffirmed, while REG revenue and volume outlooks were reduced, tied to timing expectations at the Montauk Ag Renewables facility.

News Explained

At June 30, cash was $15,757 thousand versus $149,635 thousand of long-term debt, with no disclosed share-count increase.

The company reports completed second-quarter results; power generation for sale at Turkey had commenced in July 2026, and at June 30, 2026 it held $15,757 thousand of cash against $149,635 thousand of long-term debt, making liquidity and borrowing the disclosed structural change.

Issued and outstanding common-share counts were unchanged from December 31, 2025, and the six-month cash-flow statement records no common-stock issuance. Because additional shares reduce an existing holder’s percentage ownership, the disclosed financing did not create that form of dilution.

Financing included $155,000 thousand of long-term borrowings, $44,000 thousand of long-term debt repayments, $20,000 thousand of revolver borrowings, and $105,000 thousand of revolver repayments. The six-month statement also reports $30,445 thousand of operating cash provided against $55,560 thousand of capital expenditures, so the reported investment outlay exceeded operating cash generation.

The named near-term milestone is completion of Turkey switchgear programming by mid-August, followed by the company’s expectation of consistent power and REC generation from available collected feedstock.

Key Terms

rng, mmBtu, rins, adjusted ebitda, +1 more
5 terms
rng technical
"conversion of biogas into renewable natural gas (“RNG”)"
Renewable natural gas (RNG) is methane captured from organic waste sources—like landfills, farms, or wastewater—and cleaned to match the quality of conventional natural gas. For investors, RNG matters because it turns waste into a marketable, low-carbon fuel that can create new revenue streams, qualify for environmental credits, and reduce a company’s carbon footprint much like turning trash into a sellable product.
mmBtu technical
"1.5 million Metric Million British Thermal Units (“MMBtu”) of RNG"
A MMBtu is a unit of energy equal to one million British thermal units, commonly used to measure natural gas and other fuel quantities for trading and contracts. For investors, it translates raw energy into a standardized price metric—think of it like gallons for gasoline—so changes in the MMBtu price affect producer revenues, utility costs, commodity derivatives, and the profitability of energy-related investments.
rins regulatory
"RINs from operations sold of 14.3 million"
RINs (Renewable Identification Numbers) are tradable compliance credits used to prove that a certain volume of transportation fuel comes from renewable sources under government mandates. Think of them as digital coupons companies must submit to show they met biofuel rules; their price swings can add or shave costs from refiners, fuel producers, and agriculture-linked businesses, so RIN markets can materially affect profit margins and investment value.
adjusted ebitda financial
"Non-GAAP Adjusted EBITDA of $12.3 million"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
gaap financial
"not required by or presented in accordance with GAAP"
GAAP, or Generally Accepted Accounting Principles, are a set of standardized rules and guidelines that companies follow when preparing their financial statements. They ensure consistency, transparency, and comparability across different companies, making it easier for investors to understand and compare financial information accurately. This helps investors make informed decisions based on trustworthy and uniform financial reports.

PITTSBURGH, Aug. 05, 2026 (GLOBE NEWSWIRE) -- 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 second quarter ended June 30, 2026.

Second Quarter Highlights:

  • Revenues of $54.0 million, increased 19.7 % year-over-year
  • Net income of $0.2 million, increased 104.1% year-over-year
  • Non-GAAP Adjusted EBITDA of $12.3 million, increased 144.5% year-over-year
  • RNG production of 1.5 million MMBtu, increased 3% year-over-year
  • RINs from operations sold of 14.3 million, increased 29.1% year-over-year

In July 2026, we began generating power for sale from our Turkey, North Carolina facility. This production of power is expected to be eligible to generate both swine RECs and enhanced RECs in subsequent months. As we work to increase the volumes of power and RECs that are able to be generated from our volume of produced syngas, we have identified specific programming modifications to our installed electrical switchgear. The installation of these modifications will provide for both the increase in production volumes as well as enhance protection of our processing equipment and electrical transformers. We expect to have all programming completed by mid-August and consistently generate power and RECs from all available collected feedstock volumes. 

We continue to progress with our installation of feedstock collection at our targeted 400 thousand to 450 thousand hog spaces. As of the end of July, we have entered into long term agreements with over fifty separate farming locations providing us access to at least 350 thousand hog spaces. We are currently able to collect from more than 250 thousand hog spaces and will continue farm site collection equipment installations during the second half of 2026. 

Second Quarter Financial Results

Total revenues in the second quarter of 2026 were $54.0 million, an increase of $8.9 million (19.7%) compared to $45.1 million in the second quarter of 2025. The increase is primarily related to environmental attribute revenues from RINs sold related to the distribution of RINs from our GreenWave joint venture, which had no RINs distributed and sold in the second quarter of 2025. Our second quarter of 2026 RNG volumes sold under fixed/floor-price contracts decreased approximately 80.0% compared to the second quarter of 2025 due to the expiration of fixed price pathway contracts. Our RNG commodity revenue decreased approximately 63.7% which was offset by an increase in RINs sold of 29.1%. Our RINs generated and unseparated decreased approximately 95.4% as a result of the transition to the Biogas Regulatory Reform Rule in 2025.

Operating and maintenance expenses for our RNG facilities in the second quarter of 2026 were $15.6 million, a decrease of $1.4 million (8.2%) compared to $17.0 million in the second quarter of 2025. Our McCarty facility operating and maintenance expenses decreased approximately $0.9 million primarily due to the timing of maintenance of gas processing equipment. Our Apex facility operating and maintenance expenses decreased approximately $0.5 million primarily due to timing of gas processing preventative maintenance. Our Renewable Electricity Generation operating and maintenance expenses in the second quarter of 2026 were $5.1 million, an increase of $0.3 million (5.3%) compared to $4.8 million in the second quarter of 2025. The increase was primarily driven by an increase in non-capitalizable costs of $1.2 million for our Montauk Ag Renewables project. Our Bowerman facility operating and maintenance expenses decreased approximately $0.7 million, primarily driven by the decreased wellfield operational costs and timing of gas processing preventative maintenance. We recorded approximately $8.3 million of expenses in the second quarter of 2026 related to the cost of RINs distributed from GreenWave and the costs related to pathway dispensing associated with our dispensing RNG in exclusive unique and proprietary pathways. Total general and administrative expenses were $7.7 million in the second quarter of 2026, a decrease of $1.4 million (15.2%) compared to $9.1 million in the second quarter of 2025, driven by one-time accelerated vesting of $1.6 million from certain restricted share awards in 2025. 

Operating loss in the second quarter of 2026 was $0.1 million compared to $2.4 million in the second quarter of 2025. We recognized income of $3.8 million from our GreenWave joint venture in the second quarter of 2026. Net income in the second quarter of 2026 was $0.2 million compared to a net loss of $5.5 million in the second quarter of 2025.

Second Quarter Operational Results

We produced 1.5 million Metric Million British Thermal Units (“MMBtu”) of RNG during the second quarter of 2026, an increase of 43 thousand (3.0%) compared to 1.4 million MMBtu produced in the second quarter of 2025. Our McCarty facility produced 53 thousand MMBtu more in the second quarter of 2026 compared to the second quarter of 2025 as a result of landfill host wellfield operational and collection system enhancements. Our Apex facility produced 39 thousand MMBtu more in the second quarter of 2026 as compared to second quarter of 2025 as a result of increased feedstock gas from our improvements related to the landfill collection system. Our Galveston facility produced 26 thousand MMBtu fewer in the second quarter of 2026 compared to the second quarter of 2025 as a result of the landfill host assuming responsibility of wellfield operations and maintenance in 2026. Our Atascocita facility produced 37 thousand MMBtu fewer in the second quarter of 2026 compared to the second quarter of 2025 as a result of landfill host wellfield operational and collection system enhancement project timing and planned facility maintenance. We produced approximately 44 thousand megawatt hours (“MWh”) in Renewable Electricity in the second quarter of 2026, an increase of 2 thousand MWh compared to 42 thousand MWh produced in the second quarter of 2025. Our Bowerman facility produced approximately 3 thousand MWh more in the second quarter of 2026 compared to the second quarter of 2025. The increase is primarily related to increased gas flows due to landfill host wellfield improvements.

2026 Full Year Outlook

  • RNG revenues are expected to range between $175 and $190 million (unchanged)
  • RNG production volumes are expected to range between 5.8 and 6.0 million MMBtu (unchanged)
  • REG revenues are expected to range between $23 and $26 million
  • REG production volumes are expected to range between 185 and 195 thousand MWh

The reduction in REG revenues and volumes outlook relates to our current expectations on the commencement of revenue and REG generation at our Montauk Ag Renewables facility.

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 (loss) 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.

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 are made only as of the date hereof.
