Note 35     Impairment test on Property, plant and equipment

The Group’s management defines each block or group of blocks in which the Group has operational or economic interests as a cash-generating unit (“CGU”). The classification in CGUs reflects the operational interdependence of the assets, with shared facilities and services contributing collectively to the generation of cash inflows. The grouping of assets to determine the CGUs is consistent as compared to the prior periods.

As of June 30, 2025, the divestment transaction in Ecuador described in Note 35.3 was considered to be an impairment indicator for the Perico and Espejo Blocks, as the carrying amount of the net assets related to these blocks exceeded their fair value less cost of disposal. Consequently, the net assets were impaired to their known selling price, resulting in the recognition of an impairment loss of US$ 30,989,000, comprising US$ 18,111,000 related to oil and gas properties and US$ 12,878,000 related to exploration and evaluation assets.

As of December 31, 2025, the certified reserves estimation at year-end showed declines in certain blocks compared to the prior year’s estimates. Management considered this, along with other facts related to oil price assumptions, production decline and the cash generation potential of the blocks, as indicators of impairment in the Llanos 87 and Platanillo Blocks in Colombia. As a result, the Group performed an impairment review for each of those CGUs. No impairment indicators were identified for the remaining CGUs.

The impairment tests were performed by comparing the carrying amount of each CGU to its recoverable amount, which was determined as the fair value less cost of disposal, in accordance with IAS 36 Impairment of Assets. The fair value less cost of disposal was estimated using a discounted cash flow model, as this is a commonly used approach to estimate market value in the oil and gas industry where observable market prices are not readily available. The fair value measurement used in the impairment tests is classified as Level 3 of the fair value hierarchy defined in IFRS 13 Fair Value Measurement, as it relies on inputs that are not directly observable in the market, including internal assumptions.

The key variables and assumptions applied in the valuation model included:

● Future oil prices: Based on Brent price forecasts provided by international consultancy firms and weighted with internal estimates. For the first five years, the Brent oil prices per barrel used were as follows: US$ 63.25 in 2026, US$ 70.00 in 2027, US$ 74.08 in 2028, US$ 76.32 in 2029, and US$ 77.84 in 2030.

● Price scenarios: Three scenarios (low, mid, and high) were modeled and weighted to properly reflect pricing uncertainty.

● Production and reserves: Production levels were projected based on certified risked P1, P2, and P3 reserves, or internal estimates prepared by the reservoir engineering team, as applicable, and linked to the price curves.

● Operating and structure costs: Estimated using internal historical data and consistent with GeoPark’s 2026 approved budget.

● Capital expenditures: Projected to reflect the drilling campaign necessary to develop certified reserves.

● Income taxes: Projections include expected applicable income tax rates (see Note 15).

● Discount rate: The post-tax discount rate was determined with reference to market participant assumptions and an assessment of GeoPark’s Weighted Average Cost of Capital (WACC) for each CGU. Consquently, a discount rate of 9% was applied, reflecting the specific risk profile and economic conditions of the Colombian oil and gas sector.

● Costs of disposal: Estimated based on GeoPark's recent similar transactions, reflecting the expenses expected to be incurred in a potential disposal process.

The assets subject to the impairment test include oil and gas properties, production facilities and machinery, and construction in progress. The carrying amount tested also includes mineral interests, if any.

As a consequence of the evaluation, no impairment losses were recognized.

The following amounts of impairment loss were recognized in the last three years:

Amounts in US$‘000	2025	2024	2023
Ecuador (a)	(30,989)	—	—
Chile (a)	—	—	(13,332)
	(30,989)	—	(13,332)

(a) Recognition of impairment losses due to the known selling price of the related net assets in the context of divestment transactions described in Note 35.3 for Ecuador and Note 34.7 for Chile.

With regard to the assessment of fair value less cost of disposal for the identified CGUs subject to impairment indicators, Management believes that there are no reasonably possible changes in any of the above key assumptions that would cause the carrying value of the CGUs to materially exceed its recoverable amount. A 1% change to discount rates or a 5% change in forward price estimates over the life of the reserves would have an immaterial impact on the impairment.
