Zefiro subsidiary wins $2.4M to plug 12 orphan wells in Ohio

These projects were awarded last week, and Zefiro subsidiary P&G acted quickly to place bids in order to secure the contracts, adding the Company's near-term docket of environmental remediation work. With its recently increased operating capacity across a wider geographical range, P&G now has the ability to rapidly capitalize on opportunities as new government funding is released in accordance with ramped-up efforts to plug America's orphaned wells. As P&G was one of only two bidders on two of the three projects, it is further solidifying its market position as a dominant player in the bidding pool for these contracts, as a fully integrated service provider that has been active in this market since 1970.

Bradford, Pennsylvania--(Newsfile Corp. - June 17, 2026) - ZEFIRO METHANE CORP. (Cboe Canada: ZEFI) (FSE: Y6B) (OTCQB: ZEFIF) (the "Company", "Zefiro", or "ZEFI") is pleased to announce that its subsidiary Plants & Goodwin, Inc. ("P&G") has been awarded the scope of work for three well-remediation projects set to begin in July of 2026 - Lorain 8F , Lorain 11F , and Gallia 6F . These contracts are administered by the Ohio Department of Natural Resources ("ODNR") using federal funding under the Infrastructure Investment and Jobs Act ("IIJA") which provides an allocation of USD $4.7 billion for plugging orphaned wells across the United States. An overview of the three new ODNR contracts is provided below: Lorain 8F: Five orphan wells in Lorain County, Ohio (just west of Cleveland) in the townships of Eaton and Carlisle.

One of the wells is being plugged in response to a complaint that was filed in 1989 regarding an idle well, and it was concluded after a 2022 inspection that no responsible party could be identified. ( OhioBuys Page ) Lorain 11F: Six orphan wells plus a water well also located in Lorain County, all in the township of Eaton - which has a population of approximately 5,800. One of these wells was first investigated in 2008 after a report from an area resident who noticed a "gas" odor nearby, and this well ( Weil Lowis #1 ) can now be plugged with the newly available federal funding. ( OhioBuys Page ) Gallia 6F: This is a single orphan well in Springfield township of Gallia county, Ohio, located near the state's borders with Kentucky and West Virginia. ( OhioBuys Page ) Management expects that these new ODNR contracts will generate a combined total of approximately USD $2.4 million in revenue for Zefiro, to be realized during the first quarter of Zefiro's 2027 fiscal year (three months ending September 30, 2026). This average rate of nearly USD $200,000 per well is approximately 50% higher than the USD $129,997.93 average awarded plugging cost per well under the ODNR's Orphan Well Program as published in the 2022 Orphan Well Program Annual Report ( Link to Report , Page 27).

These three contracts will add to the portfolio of projects that P&G is already performing for the ODNR agency including: Wood 12F: Second-largest orphan well remediation project in P&G history valued at USD $4.5 million for 37 wells ( Press Release ) Construction Manager at Risk (CMAR): Work for this three-year project funded under the Methane Emissions Reduction Program ("MERP") began this month (June 2026) and is slated to generate approximately USD $19.6 million in revenue for Zefiro between the present and May 2029 ( Press Release ) Zefiro Chief Executive Officer Catherine Flax commented, "Our newly expanded capacity is already proving to pay off, as we continue to benefit from the latitude that comes with more rigs and a larger workforce.

Zefiro's ability to promptly begin work after bidding on projects enables us to take full advantage of the IIJA funds that are continuing to be deployed by states that have orphaned wells. The calendar year of 2026 is proving to be quite prosperous for Zefiro as we take on new contracts, enter new markets, and continue to do more and more business with a management team that is aligned, focused, and motivated to drive growth." "Being awarded these three contracts with so few competing bids is truly a testament to the strength of our market presence in Ohio", said Luke Plants, Chief Executive Officer of P&G and Senior Vice President of Corporate Development for Zefiro. "Very few U.S. environmental services companies have the bandwidth to perform plug-and-abandonment work at a rate that can keep up with how rapidly government funding is being released.

As this pace continues to pick up, we are diligently ensuring that our crews and equipment are fully utilized, while seeking to make strategic additions to our fleet and crew size as necessary. We are thrilled to have this opportunity to add more ODNR projects to our portfolio, as we help to create safer and cleaner communities throughout the Great Lakes region." About Zefiro Methane Corp.
