ZEFIRO SUCCESSFULLY COMPLETES ALL PRE-PLUGGING MEASUREMENTS FOR ITS WEST VIRGINIA METHANE EMISSIONS REDUCTION PROGRAM CONTRACT

Zefiro Methane Corp. has successfully completed all preplugging methane quantification readings for its Methane Emissions Reduction Program (MERP) contract in West Virginia, administered by the West Virginia Department of Environmental Protection (WVDEP).

• After finishing approximately $850,000 (U.S.) worth of methane measurement work for 849 wells between October, 2025, and April, 2026, Zefiro is set to realize approximately $450,000 (U.S.) in additional revenue from postplugging readings to be done under the same contract.
• For this methane monitoring work, Zefiro realized approximately double the profit margin that it ordinarily earns from its plug-and-abandonment work. As Zefiro scales the methane monitoring component of its business, this is expected to enhance the company's profit margins at a macro level.
• As part of the process of taking these measurements, Zefiro utilized its proprietary and patent-pending wellhead containment solution which helps to ensure accurate readings.
• By further establishing its capabilities for measuring emissions, Zefiro is optimally positioning itself to continue originating carbon offsets, for which it is a requirement to have robust, high-integrity readings of gas being emitted from a given well.

This contract was initially announced in July, 2025, and from October, 2025, through April, 2026, Zefiro completed readings for a total of 849 wells, several of which were challenging to access on account of being situated in the rugged and mountainous terrains of West Virginia.

In total, approximately $850,000 (U.S.) in revenue was generated from these efforts, with approximately $450,000 (U.S.) in additional revenue to be realized from postplugging readings to be done by Zefiro after the highest-leaking wells are plugged.

Notably, Zefiro realized a profit margin from this work that is approximately double the profit margin typically generated from plug-and-abandonment (P&A) projects. This can be attributed to the work being less labour-intensive with no requirement for heavy machinery, plus lower fuel expenses (primarily from ground transportation) and fewer situational variables, which could incur unexpected costs (that is, effects of inclement weather).

Additionally, as part of this project, Zefiro was able to utilize its proprietary wellhead containment solution to expedite readings and improve their overall quality. This mechanism, which was developed in-house and has a pending U.S. patent application, helps to stabilize the environment immediately surrounding the wellhead to ensure a reliable and high-accuracy reading of emissions coming from the wellbore.

This proven use case of the wellhead containment solution helps to further strengthen Zefiro's portfolio of intellectual property, after recently announcing the very first revenues generated from a patented downthole casing expansion tool for which Zefiro subsidiary Plants & Goodwin Inc. holds the exclusive United States patent licence.

"Adding methane monitoring to Zefiro's repertoire has proven to be a game-changer for several strategic reasons that are conducive to long-term growth for the company," said Luke Plants, Zefiro's senior vice-president of corporate development. "Besides giving us the ability to earn revenue during our slower months in the winter season, it is also very scalable. We've spent this time training several of our crew members on how to take these measurements, which means that we can rapidly take on a greater volume of methane monitoring work going forward."

Mr. Plants continued: "Perhaps most importantly, this work has proven to drive approximately double the profit margin we would earn from P&A contracts. This is key because as we take on more methane monitoring work, Zefiro's entire margin profile will transform as a result of having a greater amount of high-margin emissions measuring project revenue on the books. This is a major part of how we plan to continue delivering improved value to our shareholders, and we are excited to keep building out this part of Zefiro's business model."
