Bradford, Pennsylvania--(Newsfile Corp. - April 10, 2026) - ZEFIRO METHANE CORP. (Cboe Canada: ZEFI) (FSE: Y6B) (OTCQB: ZEFIF) (the "Company", "Zefiro", or "ZEFI") is pleased to announce that it had strong performance for the winter season during the three-month period ended March 31, 2026, which is also the third quarter of Zefiro's 2026 fiscal year ("FQ3 2026").

In previous years, the months of January/February/March had been a season of relatively low business activity for Zefiro due to the seasonality of plug-and-abandonment ("P&A") work in the Appalachia region. With recent strategic expansions to its footprint in the United States, Zefiro was able to ramp up its operations during this period for overall improved performance and solid momentum continuing into the present quarter.

Below is an overview of Zefiro's business highlights from the FQ3 2026 period, signaling a positive trajectory for the Company's continued growth.

Quarterly Revenue Growth of More than 50% Year-Over-Year (YoY)

Zefiro's revenue for FQ3 2026 is expected to be approximately USD $11.0 million¹, representing an increase of over 50% compared to revenue in the same quarter of the prior year, which was approximately USD $6.94 million.

For official data and additional insights regarding the Company's financial performance during this period, please refer to Zefiro's official earnings results for FQ3 2026, which are expected to be published in mid-May 2026.

Over 35% of Wells Completed for Wood 12F (Ohio)

In February 2026, Zefiro announced that its subsidiary Plants & Goodwin, Inc. ("P&G") was awarded the scope of work for Wood 12F. This 37-well project in Wood County, Ohio is an orphan well project valued at approximately USD $4.5 million², and will be the second-largest orphan well project ever completed by P&G.

As of the end of FQ3 2026, a total of 13 of the 37 wells had been completed in Wood 12F, representing over 35% of the allocation of wells to be remediated in this project.

Richland 5 Orphan Well Project (Ohio)

During FQ3 2026, the Ohio Department of Natural Resources ("ODNR") awarded P&G the scope of work for Richland 5, an orphan well project valued at USD $816,332.50².

Louisiana: First Project Completion and Securing Contractor License

In January 2026, Zefiro announced that P&G received official approval to begin a three-month energy infrastructure project in the state of Louisiana, valued at over USD $5 million. This was completed during FQ3 2026, three weeks ahead of schedule. P&G also now holds a contractor license in the state of Louisiana, which will allow for further expansion of its presence in this key market.

Methane Monitoring/Quantification

P&G quantified methane emissions on 407 wells during the FQ3 2026 period. This component of Zefiro's core operations is expected to continue alongside its P&A activities as demand persists for methane measurement, particularly under the U.S. Environmental Protection Agency's Methane Emissions Reduction Program ("MERP").

Zefiro Chief Executive Officer Catherine Flax commented, "Zefiro performed very well in FQ3 2026, as we navigated another launch in a new region to continue growing the scale of our business. During this period, we stayed busy on the operational front while also diligently preparing for what we expect to be very active seasons in the coming spring, summer, and fall. Zefiro's management team and Board of Directors are now all fully aligned in terms of prioritizing actual revenue through proven and established channels, which I believe puts us back on track to drive compounding business growth on a continuous basis. We look forward to building upon this momentum in the present quarter with the objective of making 2026 a noteworthy year for Zefiro and its shareholders."
