Fun facts about Montauk Renewables, Inc.

Quirks, history, and lore behind MNTK — the kind of stuff that makes a stock memorable.

1
The Basics
A U.S. utilities company · listed on Nasdaq · focused on renewable energy · headquartered in Pennsylvania.
2
The Numbers
A small-cap operation with annual revenue in the range of roughly $100 million — tiny by utility standards, but growing fast in a very specific niche.
3
The History
The company traces its roots to landfill gas projects developed over decades, eventually going public as a pure-play renewable natural gas producer in the early 2020s.
4

5
The Lore
It holds a portfolio of renewable natural gas facilities across the U.S. and benefits handsomely from Renewable Identification Numbers (RINs) — the federal credits that make its economics tick.
6
The Giveaway
Named after a Long Island hamlet, this Pittsburgh-based company turns landfill methane into clean energy — and its ticker rhymes with its very Hamptons-sounding name.

AI Insight: MNTK Ratio Trends

Montauk Renewables' profitability remains deeply erratic, with ROIC turning negative and D/E nearly tripling to 0.57 over the past year.

• Operating margin has swung violently — from 34.4% in Q3 2024 to -35.5% in Q4 2024 — signaling severe quarterly earnings volatility.

• D/E ratio has risen sharply from 0.20 in Q1 2025 to 0.57 in Q1 2026, a near-tripling in leverage within four quarters.

• ROIC turned negative at -1.6% in Q1 2026, down from 5.4% in Q3 2025, reversing a brief mid-2025 recovery.

• TTM operating margin stands at -0.6% and net profit margin at just 1.2%, confirming no sustained profitability on a trailing basis.

⚠ D/E at 0.57 is highest in the data set — monitor whether debt is funding operations or capital investment with a return path.

⚠ Q3 seasonally drives outsized results (Q3 2024: 34.4% OpMargin; Q3 2025: 9.8%) — watch Q3 2026 for trend confirmation or further deterioration.

⚠ Net income was exactly 0.0% of revenue in Q1 2026 — any further cost pressure could push the company into recurring net losses.
