PITTSBURGH, Aug. 06, 2025 (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, 2025.

Second Quarter Highlights:

Revenues of $45.1. million, increased 4.1% compared to the second quarter of 2024
3.0 million RINs generated and unseparated as of June 30, 2025
Non-GAAP Adjusted EBITDA of $5.0 million, decreased 27.7% year-over-year
RNG production of 1.4 million MMBtu, flat compared to second quarter of 2024
RINs sold of 11.1 million, increased 1.1 million or 10.5% year-over-year

In the second quarter of 2025, we successfully completed the construction and commissioning of the second RNG processing facility at our Apex facility in Amsterdam, Ohio. For our Montauk Ag Renewables project in Turkey, NC, we signed a power purchase agreement in July 2025 for all the power produced from the first phase of the project. The term of this PPA begins once we commission the facility and is for 10 years covering 100% of the electric produced. The PPA price is based on set tariff and considers various impacts including but not limited to, demand, season and time of day, and an average price of $48/MWh. Finally, we entered into an agreement to form a joint venture, GreenWave Energy Partners, LLC. The primary goal of the joint venture is to help address the limited capacity of RNG utilization for transportation by offering third party RNG volumes access to exclusive unique and proprietary transportation pathways. We expect to act as the RIN separator for the joint venture.

Our profitability is highly dependent on the market price of environmental attributes, including the market price for RINs. As we self-market a significant portion of our RINs, a decision to not to commit to transfer available RINs during a period will impact our revenue and operating profit. The impact of EPA actions associated with implementation of BRRR K2 separation has temporarily impacted the RIN commitment timing of the Company. Due to BRRR, we had approximately 3.0 million RINs generated but unseparated at June 30, 2025 which reduced the amount of RINs available for sale as of June 30, 2025. In June 2025, the EPA released both the proposed RFS Standards for 2026 and 2027, a proposed Partial Waiver of 2025 Cellulosic Biofuel Volume Requirement, and the proposal to make Cellulosic Waiver Credits available for 2025. The EPA cited limitations in the capacity for RNG usage in transportation as the basis for these measures. While we are supportive of the continued emphasis on the cellulosic requirements under the RFS, we plan to participate in the comment period for the proposed rules in an effort to increase the Cellulosic Biofuel Volume Requirement.

Second Quarter Financial Results

Total revenues in the second quarter of 2025 were $45.1 million, an increase of $1.8 million (4.1%) compared to $43.3 million in the second quarter of 2024. The increase is primarily related to timing of revenues recognized under a short-term fixed priced contract in the 2025 second quarter when compared to the amount of RINs available but unsold at June 30, 2024. Our average realized RIN price in the second quarter of 2025 was $2.42 which decreased approximately 22.4% compared to $3.12 in the second quarter of 2024. Natural gas index pricing increased approximately 82.0% during the second quarter of 2025 compared to the second quarter of 2024. Operating and maintenance expenses for our RNG facilities in the second quarter of 2025 were $17.0 million, an increase of $3.1 million (22.0%) compared to $13.9 million in the second quarter of 2024. The primary drivers of this increase were timing of preventative maintenance, media changeout maintenance, and wellfield operational enhancement programs, at our Apex, McCarty, Rumpke, and Atascocita facilities. Our Renewable Electricity Generation operating and maintenance expenses in the second quarter of 2025 were $4.8 million, an increase of $0.1 million (2.0%) compared to $4.7 million in the second quarter of 2024, primarily driven by non-capitalizable expenses at our Montauk Ag Renewables projects offset by reduced wellfield collection enhancements at our Tulsa facility. Total general and administrative expenses were $9.0 million in the second quarter of 2025, an increase of $0.3 million (3.5%) compared to $8.7 million in the second quarter of 2024 driven by an increases in stock-based compensation costs as a result of acceleration of awards following termination of an employee. Operating loss in the second quarter of 2025 was $2.4 million, a decrease of $3.2 million compared to operating income of $0.8 million in the second quarter of 2024. Net loss in the second quarter of 2025 was $5.5 million, an increased loss of $4.8 million compared to $0.7 million in the second quarter of 2024.

Second Quarter Operational Results

We produced approximately 1.4 million Metric Million British Thermal Units ("MMBtu") of RNG in the second quarter of 2025, flat compared to 1.4 million MMBtu produced in the second quarter of 2024. At our Rumpke facility, we produced 67 MMBtu more in the second quarter of 2025 compared to the second quarter of 2024 as a result of previously disclosed plant processing equipment failure that occurred in the second quarter of 2024. Offsetting the increase was the fourth quarter of 2024 sale of our Southern facility which produced 22 MMBtu in the second quarter of 2024. We produced approximately 42 thousand megawatt hours ("MWh") in Renewable Electricity in the second quarter of 2025, a decrease of 3 thousand MWh compared to 45 thousand MWh produced in the second quarter of 2024. Our Bowerman facility produced approximately 2 thousand MWh less in the first quarter of 2025 compared to the first quarter of 2024 as a result of timing of preventative engine maintenance that was completed in the second quarter of 2025.

Reaffirmed 2025 Full Year Outlook

RNG revenues are expected to range between $150 and $170 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 $17 and $18 million (unchanged)
REG production volumes are expected to range between 178 and 186 thousand MWh (unchanged)

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 (loss) 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.
