Zefiro Announces US$40 Million Backlog of Awarded Government Projects Extending Through June 2029

Approximately US$4.9 million of the government backlog is expected to be performed during the current quarter

Zefiro was awarded an Exploratory contract by the Ohio Department of Natural Resources, adding a new revenue stream to its growing portfolio of services.

Bradford, Pennsylvania--(Newsfile Corp. - October 19, 2026) - Zefiro Methane Corp. (CBOE CA: ZEFI) (FSE: Y6B) (OTCQB: ZEFIF) (the "Company", "Zefiro", or "ZEFI"), a North American environmental services company specializing in methane abatement and the plugging of orphaned and end-of-life oil and gas wells, today announced that its backlog of awarded government well-plugging projects totals approximately US$40 million, with work extending through June 2029.

Zefiro expects to perform approximately US$4.9 million of work toward the backlog during the current quarter — the second quarter of fiscal 2027, ending December 31, 2026. The remaining approximately US$34.6 million is expected to be performed primarily over calendar years 2027 and 2028, with the last of the contracts in the backlog scheduled to conclude in June 2029. Management expects the backlog to provide a strong, continued pipeline of revenue through mid-2029.

The backlog reflects government-funded projects only and does not include work for Zefiro's corporate clients, such as oil and gas operators. Corporate projects typically carry short lead times, with work scheduled and performed soon after award. As a result, the backlog represents only a portion of the work the Company expects to perform in any given period.

Major components of the backlog include the following previously announced awards:

• A three-year, US$19.6 million Construction Manager at Risk ("CMAR") contract from the Ohio Department of Natural Resources ("ODNR") to manage the plugging and abandonment of approximately 200 high-priority marginal wells across Ohio, running through May 2029
• A US$11.5 million state-funded well-plugging contract from a state environmental protection department in the Great Lakes region, with work scheduled from November 2026 through June 2029
• US$2.4 million in federally funded ODNR projects to plug 12 orphan wells in Lorain and Gallia Counties, Ohio
• Three federally funded well-plugging projects in Ohio and Pennsylvania valued at approximately US$1.9 million, covering 12 orphaned wells

The backlog also includes three additional Ohio well-plugging projects that have not been previously announced, together representing approximately US$5.0 million of work across 48 wells.

Exploratory Contract in Southeastern Ohio

Zefiro has also been awarded an Exploratory contract by ODNR for work in southeastern Ohio. Exploratory projects are part of ODNR's Orphan Well Program and are designed to better evaluate the equipment, materials, and conditions of orphan wells before they are plugged.

The work consists of assessment, site preparation, and initial excavation to expose each well — including removing surface equipment to identify the casing, tubing, and rods present, and running a depth meter to locate the first obstruction in the wellbore — so that the well is ready to be plugged once a separate plugging contract is awarded.

Because exploratory work is contracted separately from plugging, the award represents an additional revenue stream for Zefiro. It also adds to the Company's growing portfolio of services, which spans well plugging and abandonment, methane measurement and monitoring, carbon sequestration, and carbon credit origination — and now includes exploratory work.

Management Commentary

Zefiro Chief Executive Officer Catherine Flax commented: "When we reported our fiscal 2026 results, we said fiscal 2027 would be about converting the largest contracted pipeline in our history into revenue. This backlog, none of which is yet reflected in our reported results, gives Zefiro a multi-year base of government-funded revenue through mid-2029 that complements our growing private-sector business.

"The Exploratory contract is a welcome addition in its own right. It brings Zefiro into an earlier stage of the remediation process using the same crews we deploy every day, and it gives us another way to support state agencies as they work through their inventories of orphan wells," concluded Flax.

Zefiro Senior Vice President of Corporate Development Luke Plants added: "A backlog of this size and duration changes how we can run the business. Knowing where our rigs and crews will be working through mid-2029 allows us to sequence projects efficiently, plan mobilizations well ahead of time, and keep our people consistently in the field, which benefits our employees, our agency partners, and our shareholders alike."
