Epsilon Energy Ltd.

We perform a quantitative impairment test whenever events or changes in circumstances indicate that an asset group's carrying amount may not be recoverable, over proved properties using the published NYMEX forward prices, basis differentials, timing, methods and other assumptions consistent with historical periods. When indicators of impairment are present, GAAP requires that the Company first compare expected future undiscounted cash flows by asset group to their respective carrying values. If the carrying amount exceeds the estimated undiscounted future cash flows, a reduction of the carrying amount of the properties to their estimated fair value is required. Additionally, if an exploratory well is determined not to have found proved reserves, the costs incurred, net of any salvage value, should be charged to expense.

During the nine months ended September 30, 2025, Epsilon recorded an impairment of $2.7 million fortwo wells drilled in Alberta, Canada. The impairment was a result of a decrease in estimated reserves due to early production coming in below expectations, cost overruns and lower forward commodity prices. During the three months ended September 30, 2025, no impairment was recorded.

During the three and nine months ended September 30, 2024, no impairment was recorded. For the year ended December 31, 2024, the Company had $0.53 million of impairment reflected in proved properties on the Consolidated Balance Sheets. To be consistent with the current presentation, the prior year impairment has been reclassed to accumulated depletion, depreciation, amortization and impairment on the Consolidated Balance Sheets.
