Zefiro has realized its very first earnings from a patented casing expansion tool, after two corporate clients of ZEFI subsidiary Plants & Goodwin, Inc. have utilized Radial Casing Solutions' REED device on job sites in Pennsylvania.

These two proven and successful deployments with third-party clients gives P&G the ability to further market the REED device to other end-user licensees in the United States, as P&G is the exclusive U.S. patent license holder for REED in addition to other technologies developed by RCS.

With this range of advanced intellectual property at its disposal, Zefiro is further strengthening its competitive advantage as the leading plug-and-abandonment business in North America.

Bradford, Pennsylvania--(Newsfile Corp. - April 21, 2026) - ZEFIRO METHANE CORP. (CBOE CA: ZEFI) (FSE: Y6B) (OTCQB: ZEFIF) (the "Company", "Zefiro", or "ZEFI") is pleased to announce that two commercial deployments of the patented wellbore casing expansion technology Radial Elastomer Expansion Device ("REED") have successfully been completed for two corporate clients in the resources sector on job sites in Pennsylvania.

This execution by Zefiro subsidiary Plants & Goodwin, Inc. ("P&G") marks the Company's first-ever earnings from this intellectual property, a revenue stream that can complement Zefiro's core operations. Over the past two fiscal quarters combined, these operations were largely responsible for generating more than USD $22 million in revenue and adjusted EBITDA of USD $3.8 million (Press Release ).

The REED device is built around a patented technology by Radial Casing Solutions Ltd. ("RCS"), which uses surface-level hydraulic pressure to expand elastomer elements on the inside of wellbore casing to seal leak pathways. In layperson's terms, casing inside of a wellbore is expanded by REED to prevent underground leaks of gases such as methane from reaching the surface. This common issue sometimes requires well-drilling or plugging work to be revised after being initially completed. Using REED proactively prevents such revision work from being needed, and can provide firms such as P&G who plug oil and gas wells with a useful value-add to offer their clients.

In August of 2024, Zefiro announced that P&G acquired a minority ownership interest in RCS, which was named Winterhawk Well Abandonment Ltd. at the time. P&G also entered into an exclusive patent license agreement for RCS' U.S. patents, making P&G the only company that can utilize or sublicense RCS' innovations such as REED in the United States.

More information about REED can be found on RCS' website:

Zefiro Senior Vice President of Corporate Development Luke Plants commented, "We are quite happy to have executed these deployments and further advanced our playbook for making the most out of RCS' technologies, for which we hold an exclusive license of their U.S. patents. Gas often comes to the surface of wellbores from sustained casing pressure or surface casing vent flows. When this happens, the cost to remediate the issue can be in the hundreds of thousands to millions of U.S. dollars - whereas using the REED device to expand the wellbore casing costs a mere fraction of this amount. We now include REED in P&G's modular, turnkey plug-and-abandonment package, and by beginning to more widely license the technology, we can offer this capability to other operators across the United States."
