As mentioned in Note 2.2.7, the CGU to which goodwill has been allocated, are periodically tested for impairment by including the allocated goodwill in their carrying amount.

This analysis is performed at least annually and whenever there is any indication of impairment. Furthermore, it is analyzed whether certain changes in the valuation assumptions used could give rise to differences in the result of the impairment test.

The BBVA Group performs estimations on the recoverable amount of certain CGU by calculating the value in use through the discounted value of future cash flows method.

–The forecast cash flows, including net interest margin and cost of risk, estimated by the Group's management, and based on the latest available budgets for the next 5 years, considering the macroeconomic variables of each CGU, regarding the existing balance structure as well as macroeconomic variables such as the evolution of interest rates and the GDP of the geographical area where the CGU is located, among others.

–The discount rate on future cash flows, which coincides with the cost of capital assigned to each CGU, and which consists of a risk-free rate plus a premium that reflects the inherent risk of each of the businesses evaluated.

The focus used by the Group's management to determine the values of the assumptions is based both on its projections and past experience. These values are verified and use external sources of information, wherever possible.

The Group’s most significant goodwill corresponds to the CGU in Mexico, the most relevant assumptions used in the impairment test of this CGU as of December 31, 2025, 2024 and 2023 are as follows:

In accordance with paragraph 33.c of IAS 36, as of December 31, 2025, the Group used a growth rate of 5.2 % based on the real GDP growth rate of Mexico, the expected inflation rate and the potential growth of the banking sector in Mexico.

The assumptions with a greater relative weight and whose volatility could have a greater impact in determining the present value of the cash flows starting on the fifth year are the discount rate and the growth rate. The table below shows, in a simplified way, the relative variation by which the CGU recoverable amount would increase (or decrease) as a result of a reasonable variation (in basis points) of each of the key assumptions, considered in isolation as of December 31, 2025, where, in each case, their value in use would continue to exceed their book value:


SENSITIVITY ANALYSIS FOR MAIN ASSUMPTIONS - MEXICO

	Increase of 50 basis points (1)		Decrease of 50 basis points (1)
Discount rate	(3)	%	4	%
Growth rate	2	%	(2)	%

(1) The use of very different discount or growth rates would be inconsistent with the macroeconomic assumptions under which the Unit builds its business plan, such as inflation assumptions or interest rate curves used to determine cash flows.

The impairment tests carried out on the rest of the CGUs have not detected significant impairment. Likewise, the sensitivity analysis on the main assumptions carried out for the rest of the CGU of the Group indicate that their value in use would continue to exceed their book value.
