• Zefiro has successfully closed on a USD $4.3 million agreement to acquire the equipment of Viking Well Service which includes five derrick rigs as well as several other key units of machinery to be added to Zefiro's fleet.

• As a result of this acquisition, Zefiro will have coverage in five new states where it has not previously operated (New Jersey, Michigan, Indiana, Illinois, and Iowa) while also expanding its footprint in four existing states.

• This added geographical coverage and increased total operating capacity is expected to boost Zefiro's annual revenue by approximately USD $10 million per year in the near term. This adds to the Company's ongoing revenue, with over USD $22 million in revenue reported over the first half of the Company's fiscal year (Press Release).

Bradford, Pennsylvania--(Newsfile Corp. - May 6, 2026) - ZEFIRO METHANE CORP. (CBOE CA: ZEFI) (FSE: Y6B) (OTCQB: ZEFIF) (the "Company", "Zefiro", or "ZEFI") is pleased to announce that its subsidiary Zefiro Ohio Holdings LLC has completed the closing of an agreement in which it will acquire the equipment of Viking Well Service for USD $4.3 million.

This transaction will result in Zefiro gaining a presence in five new states (New Jersey, Michigan, Indiana, Illinois, and Iowa), as well as an expanded presence in four states where Zefiro is already operating (Ohio, Pennsylvania, New York State, and West Virginia).

Zefiro's management believes there is an opportunity to increase revenue in excess of USD $10 million per year as a direct result of the additional capacity the acquired equipment adds. The forecast is an estimate and is based on Zefiro's internal projections on day rates and equipment utilization.

Equipment included in this acquisition includes five derrick rigs (one of which is pictured below) and two rig-assist snubbing units, in addition to trucks, trailers, catwalks, pumps, and power swivels.

"This equipment acquisition is a very exciting milestone as we pursue our journey to increase Zefiro's market share in the environmental services space," said Zefiro Chief Executive Officer Catherine Flax. "Management currently estimates that the acquired equipment could contribute approximately USD $10 million or more in top-line revenue per year as a result of this transaction, which positions Zefiro quite well for continued growth. We are looking forward to putting this equipment into action during the busy season for our core operations of environmental services, which is proving to be the key consistent driver of Zefiro's revenue and EBITDA."

Zefiro Senior Vice President of Corporate Development Luke Plants commented, "From an operational perspective, the market presence that Zefiro gains as a result of this equipment acquisition will have a lot of strategic value. Between the ability to take on additional business in our existing territories while also entering the marketplace in new territories, I expect that we will be able to approximately double our customer base of Exploration & Production ("E&P") accounts as corporate clients. Besides adding to top-line and bottom-line revenue, this would also help to de-risk customer concentration by spreading our business activity across a greater range of clients and geographical regions. Our team is very excited for the opportunities this equipment acquisition will create for Zefiro and its stakeholders."
