Montauk Renewables Reports $45.1 Million in Q2 2025 Revenues, Faces Net Loss

Montauk Renewables, Inc. reported total operating revenues of $45.1 million for the second quarter of 2025, reflecting a 4.1% increase from $43.3 million in the same period of 2024. The growth was primarily driven by a rise in Renewable Natural Gas (RNG) revenues, which increased by 5.1% to $40.8 million, while revenues from Renewable Electricity Generation decreased by 4.5% to $4.3 million. The company experienced a decline in the average realized price of Renewable Identification Numbers (RINs), which fell by 22.4% to $2.42, contributing to a net loss of $5.5 million for the quarter, compared to a loss of $0.7 million in the prior year.

In the first half of 2025, Montauk's total revenues reached $87.7 million, an increase of 6.8% from $82.1 million in the first half of 2024. The increase in revenue was attributed to a rise in RNG commodity revenues, which grew by 8.9% to $79.3 million, despite a significant decrease in recognized RIN revenues. The company produced 2,802 MMBtu of RNG during the first half of 2025, a slight increase of 0.3% compared to the previous year. However, the total RIN generation decreased by 18.7% to 20.3 million RINs, reflecting challenges in the market.

Montauk Renewables has made strategic advancements, including the successful commissioning of the Second Apex RNG Facility in June 2025, which is expected to enhance production capacity by 2,100 MMBtu per day. The company is also exploring opportunities in livestock farm projects, which are anticipated to provide higher revenue potential due to favorable carbon intensity scores. Additionally, Montauk has entered into a joint venture, GreenWave Energy Partners, aimed at expanding RNG utilization in transportation.

Operationally, Montauk faced challenges with wellfield extraction and gas collection at several facilities, impacting production volumes. The company reported an increase in operating expenses, which rose by 11.8% to $89.7 million for the first half of 2025, driven by higher maintenance and operational costs. The company’s total debt increased to $70 million as of June 30, 2025, compared to $56 million at the end of 2024, reflecting ongoing investments in development projects.

Looking ahead, Montauk Renewables anticipates continued growth in RNG production and revenue, supported by strategic projects and market demand for renewable energy. However, the company remains cautious about potential regulatory changes and market conditions that could impact its operations and financial performance.
