Viva Energy Group (ASX:VEA) changed an accounting judgement applied in its financial report for the year ended Dec. 31, 2025, resulting in an increase in impairment expenses of AU$25 million, following a review conducted under the Australian Securities and Investments Commission's (ASIC) financial reporting and audit surveillance program, according to a Monday statement.

Viva Energy recognized a total impairment expense for its retail convenience sites for the 2025 year of AU$558.8 million.

The regulator reviewed Viva Energy's financial report and raised concerns about its approach to impairment testing of its convenience retail sites. This involved assessing some sites as a group on the basis that the Shell Card is a wholesale offering across Viva Energy's Australia-wide network, rather than assessing them all on an individual site basis.

ASIC believed that this group approach was inappropriate because Viva Energy was able to assess impairment for each retail site included in the Shell Card cash-generating unit.

Its shares jumped 3% in recent trading on Monday.
