what it is
Montauk turns landfill gas into renewable fuel and electricity, then sells both into markets shaped by government credits.
how it gets paid
Last year Montauk Renewables made $176M in revenue. renewable natural gas fuel sales was the main engine at $106M, or 60% of sales.
why it's growing
Revenue grew 0.4% last year. The number that mattered was 33.5% gross margin.
what just happened
Latest results showed $133M in revenue, but EPS fell to -$0.01 and the quarter still looked messy.

What they do
Montauk turns landfill gas into renewable fuel and electricity, then sells both into markets shaped by government credits.
Montauk already has 12 renewable natural gas projects and 3 renewable electricity projects, with 13 operating sites on the ground. That matters because this business is infrastructure-heavy. You do not copy a landfill gas network overnight, and existing projects give Montauk a head start when fuel credits lift pricing.

pipeline-grade gas production
Renewable natural gas
$161M · 91% of revenue
It's the whole story. Management is targeting $175M–$190M of RNG revenue in 2026, which means this single segment still does nearly all the heavy lifting.
91% of revenue
regulatory credit monetization
Environmental credits (RINs)
6.8M unsold RINs
It ended 2024 with 6.8 million unsold RINs in inventory. That's not just a backlog. It's a pile of value that depends on pricing, timing, and rules staying favorable.

$11M · 6% of revenue
This piece is only $11M of revenue today. It helps diversify the mix, but not enough to offset weakness in the much larger RNG business.

Key numbers
0.5%
operating margin
Jargon: operating margin → what the company keeps after operating costs → so what: Montauk turned $176M of sales into only about $0.9M of operating profit.
4.1%
return on capital
Jargon: return on capital → profit earned on the money invested in the business → so what: Montauk is earning back 4.1 cents for each dollar tied up in operations.
$59M
long-term debt
Debt is 23% of capital. So what: the balance sheet is manageable, but it looks heavy next to a business earning just 0.5% operating margins.
24.3x
p/e ratio
Jargon: P/E → stock price divided by earnings → so what: you are paying 24.3 times profit for a company expected to earn $0.07 a share in 2024.
Financial health
C++
strength
- balance sheet grade C++ — below average — limited financial resources
- risk rank 3 — safer than 50% of stocks
- price stability 10 / 100
- long-term debt $59M (23% of capital)
C++ — below average. watch for debt servicing and cash burn.

What just happened
missed estimates
Latest results showed $133M in revenue, but EPS fell to -$0.01 and the quarter still looked messy.
Revenue jumped 194% vs. prior year, but earnings went the other way, down 125% vs. prior year. That is the whole Montauk argument in one quarter: strong top-line moves, weak profit conversion.

the number that mattered
The number that mattered was 33.5% gross margin, because gross profit looked decent while bottom-line profit still disappeared further down the income statement.

What could go wrong
The top risk here is RIN pricing and environmental policy exposure. Montauk ended 2024 with 6.8 million unsold RINs, so regulation is not background noise — it's inventory value sitting on the balance sheet.
high
RIN pricing and rule changes
The company relies on EPA and CARB frameworks to monetize credits. With 6.8M unsold RINs at the end of 2024, weaker pricing or less favorable rules would hit both realized revenue and the value of inventory already built.
This risk sits next to the entire credit monetization story and can pressure cash generation fast.
high
Margin staying stuck near 1%
Net income fell 82% to $1.7M in 2025, leaving net margin at about 1%. When a business keeps one cent on the dollar, almost any operational miss matters more than investors want it to.
A thin margin leaves almost no shock absorber for costs, downtime, or soft pricing.
med
RNG concentration
RNG generated $161M of $176M total revenue. That's 91% of the business in one line item. If project volumes slip or a major site underperforms, there is no second engine large enough to hide it.
One segment drives the upside and the downside. That's focus until it isn't.
med
Debt servicing after refinancing
Long-term debt is $59M, or 23% of capital, after the March 9, 2026 refinancing. That debt load is manageable only if profits recover from the current $1.7M level.
Refinancing changed the schedule. It did not change the need for better earnings.
Four core risks, one common thread: a business with 1% net margin does not get many bad surprises before the equity story changes.

Pay attention to
metric
net margin recovery
The key number is still the simplest one: can the company move net margin materially above 1% while keeping revenue around the current $176M base.
calendar
Q1 2026 earnings report
Expected May 14, 2026. You want to see whether the $175M–$190M 2026 RNG revenue target still looks realistic after the first quarter.
risk
RIN inventory monetization
The 6.8M unsold RINs matter because they turn regulatory policy into balance-sheet exposure. Watch pricing, timing, and any commentary around inventory drawdown.
trend
capital spending versus earnings power
Planned 2026 non-development capex of $20M–$25M is not small relative to $1.7M of profit. Growth spending only works if operating returns start to show up.
