Montauk Renewables reports net loss in Q2

Pittsburgh-based landfill gas-to-energy technology provider Montauk Renewables Inc. has reported a net loss of nearly $5.5 million in the second quarter of 2025, which follows a net loss of less than $500,000 the previous quarter.

In the first six months of 2025, Montauk has recorded a net loss of about $5.95 million, which contrasts with more than $1.1 million in profits recorded in the first half of 2024.

The company’s revenue in the second quarter of about $45 million represented a 4.1 percent increase compared with one year earlier, and the firm says its production of renewable natural gas (RNG) was flat compared with the second quarter of 2024.

Operationally, the company completed the construction and commissioning of the second RNG processing facility at its Apex facility in Amsterdam, Ohio.

For its Montauk Ag Renewables project in Turkey, North Carolina, the company signed a 10-year power purchase agreement this July for all the power produced from the first phase of the project.

Montauk also has agreed to form a joint venture called GreenWave Energy Partners LLC it says will help address the limited capacity of RNG utilization for transportation by offering third party RNG volumes access to exclusive unique and proprietary transportation pathways.

The company says its profitability is highly dependent on the market price of environmental attributes, including renewable identification numbers.

In June, the U.S. Environmental Protection Agency released a proposed partial waiver of 2025 Cellulosic Biofuel Volume Requirement, citing limitations in the capacity for RNG usage in transportation as the basis for these measures.

Looking ahead, Montauk is forecasting full year RNG revenue of between $150 and $170 million but does not forecast a full year profit or loss figure.
