Q1 2025 total revenues were $42.6 million, up 9.8% year-over-year, primarily driven by increased RINs sold, though realized RIN prices decreased to $2.46 from $3.25 in Q1 2024.
Adjusted EBITDA for Q1 2025 was $8.8 million, down 7.2% year-over-year; net loss was $0.5 million compared to net income of $1.9 million in Q1 2024.
Regulatory uncertainty from EPA delays and new rules impacted RIN sales timing, but Montauk has no exposure to the 2024 compliance waiver and has entered commitments to transfer most 2025 RINs at prices near the D3 RIN index.
Major development projects include the North Carolina swine waste-to-energy facility (significant production expected in 2026), expansion at the American Environmental Landfill in Tulsa, and relocation/upgrade of the Rumpke site with added food-grade CO2 processing (commissioning expected Q3 2027).
Full-year 2025 outlook reaffirmed: RNG production volumes expected between 5.8–6.0 million MMBtu with revenues of $150–170 million; renewable electricity production of 36–40k MWh with revenues of $17–18 million.
