Intact: The reason to own it still holds.
Montauk Renewables aims to grow RNG revenues to $175-$190 million in 2026. The company also targets REG revenues between $33 and $37 million. Recent earnings beats show improving execution. The stock has gained 45% over 63 days, showing momentum.
Montauk Renewables is still loss-making with negative free cash flow yield. Revenue growth and REG segment delivery remain uncertain. The stock trades at a high PE of 44 versus peers at 23. Analyst revisions have been mostly down recently.
The price is about 17% above our fair value near $1.42. Analysts expect 26% revenue growth, which aligns with management guidance. Our view is cautious given mixed execution and high valuation.
Breaks if: Earnings miss or guidance cut in more than 1 of next 4 quarters
Breaks if: REG revenues fall below $33 million in FY26

A long-form read on the 1–3 year hold thesis. It updates when the weekly evidence changes.
This investment represents a turnaround scenario, as MNTK is working to improve its financial performance while navigating challenges. The current thesis state indicates a cautious watch due to recent earnings misses and mixed revenue guidance.
The market seems to price in a high level of fragility, with an unjustified premium compared to peers. The expectations gap suggests that investors are anticipating better performance than what has been delivered recently.
Management is focused on increasing revenues from renewable natural gas, which shows a stable trajectory. However, the guidance for REG revenue has been revised downward, indicating potential challenges ahead.
Key factors include the potential for MNTK to cut guidance in the next earnings call, which could negatively impact sentiment. Additionally, the performance of sector leaders and inflation trends will be crucial for MNTK's future outlook.
The most important moves since the prior daily snapshot.
Yes, our read has strengthened. The latest earnings beat supports a positive outlook. Revenue is expected to surge to $175-$190 million in 2026. There are no new threats impacting the thesis.
