Fair value hierarchy The Company’s valuation techniques used to determine and disclose the fair value of its financial instruments are based on the following hierarchy: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2: Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable; and Level 3: Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable. The fair value for the financial assets (excluding cash and cash equivalents) and financial liabilities shown in the consolidated statements of financial position at December 31, 2023 and 2024 is as follows:

Fair value of derivative financial instruments is valued using valuation techniques with market observable inputs. To determine its Level 2 fair value, the Company applies different valuation techniques including forward pricing and swaps models, using present value calculations. The models incorporate various inputs including credit quality of counterparties, foreign exchange spot and forward rates and interest rate curves. Fair value of debt Level 2 has been determined using a model based on present value calculation incorporating credit quality of AMX. Until September 2024 the fair value of VTR bonds in AMX B.V. as debt instruments at fair value through OCI, were classified as Level 1 in order they are guaranteed with shares listed on the regulated market. The Company’s investment in equity investments at fair value, specifically the investment in Verizon in 2024 and 2023, and also KPN in 2023, is valued using the quoted prices (unadjusted) in active markets for identical assets. The net realized loss related to derivative financial instruments for the years ended December 31, 2023 and 2024 was Ps. (9,420,419) and Ps. (2,111,926) respectively. The fair value of the asset revaluation was calculated using valuation techniques, using observable market data and internal information on transactions carried out with independent third parties. To determine fair value we use level 2 and 3 information, the Company used inputs such as average rents, contract term and discount rates for discounted flow modeling techniques; in the case of discount rates, we use level 2 data where the information is public and is found in recognized databases, such as country risks, inflation, etc. In the case of level 3 data, the information is mainly internal based on lease contracts entered into with independent third parties. During the end of the period ended December 31, 2023 and 2024, there were no transfers between the Level 1, Level 2 and Level 3 fair value measurement hierarchies.
