ZEFIRO SUBSIDIARY DEPLOYING SECOND AND THIRD RIGS FOR MAJOR U.S. NATURAL GAS PRODUCER

Starting next month, Zefiro Methane Corp.'s subsidiary, Plants & Goodwin Inc. (P&G), will deploy two additional rigs for a major United States-based natural gas producer client to plug gas wells located in New York, Pennsylvania, West Virginia and Kentucky.

• One of Zefiro subsidiary P&G's major corporate clients is ramping up its annual plug and abandonment campaign for 2026. One rig was already under contract for the full year, though two additional rigs are being engaged to actively service an increased workload.
• This campaign will consist of at least 26 wells in Pennsylvania, New York, West Virginia and Kentucky, most of which will require specialized advanced tactics to properly plug compared with ordinary oil/gas wells.
• Although P&G's fleet was already fully committed, the addition of new rigs through a recent strategic equipment acquisition will allow for a third rig to be deployed.
• After reporting earnings with over $33-million (U.S.) in revenue and $4.25-million (U.S.) in adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) for the past three fiscal quarters, Zefiro is pursuing continued revenue growth as an established leader in oil/gas well plug and abandonment.

These well-plugging projects reflect the energy industry's increasing efforts to pro-actively meet asset retirement obligations (ARO) in order to prevent long-term environmental impact from oil/gas wells that are no longer producing. These corporate client engagements are undertaken concurrently with several public sector projects, as outlined in Zefiro's April 16, 2026, press release providing an overview of the company's docket for the 2026 spring season.

This client already had one of P&G's rigs engaged for the full calendar 2026 year as part of its annual plug-and-abandonment campaign, for which it has retained P&G each year since 2017.

The second additional rig being deployed will work in parallel with the first rig in Pennsylvania and New York for the purpose of more rapidly remediating the client's wells that are scheduled to be decommissioned in 2026.

The third additional rig will be deployed from approximately June through October of 2026 in West Virginia and Kentucky. The addition of this third rig to the client's scope of work was only possible as a result of the recently announced $4.3-million (U.S.) acquisition of Viking Well Service's equipment, which included five derrick rigs. The entirety of P&G's rig fleet prior to this was already committed between client projects and standard maintenance/inspection cycles.

Given its specialized equipment fleet and significant operational expertise in oil/gas well site remediation, P&G has proven itself as a service provider who can reliably handle projects that are complex or unique in nature. Several of the 26 wells to be plugged for the client were drilled to a much greater depth compared with ordinary gas wells, with many situated in areas that are difficult to access due to rugged/steep terrains. P&G's crews are experienced with such variables, allowing them to safely and efficiently navigate these remediation projects to completion.

Zefiro chief executive officer Catherine Flax commented: "After several recent key milestones such as our third consecutive profitable fiscal quarter and a $4.5-million equity financing, Zefiro's management team is very much focused on propelling continued growth. One of our foremost considerations in decision making is ensuring that a given deal or maneuver has a realistic and straightforward path towards realizing revenue. This is something we contemplated thoroughly as part of the Viking Well Service equipment acquisition ... and in just a matter of weeks, we will have gone from finalizing the transaction to utilizing this new equipment. Management expects this will bring in new revenue and further strengthen an already valuable client relationship. Our team knows how to execute, and we are thrilled to share with our investors this great example of how we are actively generating business value."

Luke Plants, who is Zefiro's senior vice-president of corporate development, as well as P&G's chief executive officer, added: "Outside of this industry, it is not widely known that demand for well-plugging services in the United States is overwhelmingly persisting. There are very high barriers for entry to this space, which puts operations such as ours in fairly limited supply, allowing us to preserve our market share. We can also grow this market share through strategic acquisitions, and this is exactly how we were able to bolster our relationship with this client to further support their annual plug-and-abandonment campaign for the ninth year in a row. We look forward to these deployments as we continue to deliver results to cap off Zefiro's 2026 fiscal year."
