Zefiro Methane Corp (Cboe: ZEFI) (OTCQB: ZEFIF) has a dirty job to do but, as they say, someone has to do it, and this company does it well.
Zefiro, an environmental services firm, cleans up and plugs end of life oil and gas wells, specializing in methane abatement, which involves reducing or preventing the release of methane gas into the atmosphere.
Environmentally speaking, methane (a greenhouse gas) traps much more heat than CO₂, making it a big contributor to global warming. What’s encouraging, though, is methane has a short atmospheric lifetime (about 12 years), and is often cheaper and easier to reduce than CO₂.
Zefiro, a C$42.6 million market cap company, has generated more than US$30 million in revenue since 2023, about US$22 million of which was achieved during the first six months of fiscal 2026, along with US$3.8 million in adjusted EBITDA during the period.
For Q3 2026, ending March 31, Zefiro expects revenue of approximately US$11.0 million, an increase of more than 50% from the same period a year earlier. And, the company said recently it is on target to achieve a US$40.0 million revenue run rate for fiscal year 2026.
The 2022 U.S. Infrastructure Investment and Jobs Act (IIJA) has allocated $4.7 billion to states for grant-funded plugging and abandonment (P&A) services, providing plenty of revenue-producing opportunities for Zefiro. In fact, in February the company announced that it had begun working on an orphan well project in Ohio that is expected to contribute about US$4.5 million in revenue.
Zefiro estimates there are 2.2 million abandoned end-of-life wells in the U.S., which could translate into a Total Addressable Market (TAM) of US$400 billion to $600 billion.
Another plus for this company is the insider ownership of its common shares. CEO Catherine Flax owns more than 7.1 million Zefiro shares, while the company’s Directors collectively own, either directly or indirectly, nearly 5 million shares, according to a filing dated February 12, 2026. Insiders have also continued purchasing company shares as recently as April 6 to 9, 2026.
Zefiro’s stock price recently closed at C$0.47. There are 90,628,622 issued and outstanding common shares.
