Montauk Renewables (MNTK) Q1 2025 earnings summary

Executive summary

• Q1 2025 revenues increased 9.8% year-over-year to $42.6 million, driven by higher RIN sales and monetization of prior period RINs, despite a 24.3% drop in average realized RIN prices and regulatory delays impacting RIN commitments.
