In accordance with the Federal Labor Law, the Company is required to pay a seniority premium as a retirement benefit if an employee retires and has served at least 15 years. The seniority premium consists of a single payment equal to 12 days’ salary for each year of service based on the employee’s most recent salary, but without exceedingly twice the current minimum wage established by law.

In addition, payments for the termination benefit plan consist of an equivalent of 20 days for each year worked and 90 days based on pensionable salary determined based on actuarial calculations made by external actuaries, using the projected unit credit method.

The Mexican plans normally expose the Company to actuarial risks such as: investment risk, interest rate risk, longevity risk and salary risk.


Investment risk		The present value of the defined benefit plan obligations is calculated using a discount rate that is determined by long-term government bond yields. To select the discount rate, the yield rate of the bond is considered, which is similar to the duration of the obligations of the Company’s labor liabilities. The average days on which benefit payments are due and not the days that the bonus is due to expire are taken into account, which means that the discount rate depends on the expectation of the flow of payments of the benefits plan.

Interest risk		A decrease in the interest rate of the bonds may increase the liabilities of the plan, however, this is partially offset by an increase in the plan’s debt investment performance.

Longevity risk		The present value of the defined benefit plan liability is calculated by reference to the best estimate of the mortality of plan participants both during and after their employment. An increase in the life expectancy of the plan participants will increase the plan’s liability.

Salary risk		The present value of the defined benefit plan liability is calculated by reference to the future salaries of plan participants. As such, an increase in the salary of the plan participants will increase the plan’s liability.

The actuarial calculation of the defined benefit obligation was calculated as of December 31, 2025, 2024 and 2023 by actuaries certified by the National School of Actuaries (Colegio Nacional de Actuarios de México). The present value of the defined benefit obligation, and the related current service cost and past service cost, were measured using the projected unit credit method.

The principal assumptions used for the purposes of the actuarial valuations are as follows:


		Year ended December 31,
		2025		2024		2023
Discount rate (see note 5 a.)		9.40	%	10.15	%	9.85	%
Expected rate of salary increase		5.8	%	5.8	%	5.8	%
Average longevity at retirement age for current employees (years)		13		14		14
Inflation		4.0	%	4.0	%	4.0	%

The amounts recognized in the consolidated statement of income and other comprehensive income in respect of these defined benefit plans are as follows:


		Year ended December 31,
		2025			2024			2023
Service cost:
Current service cost		Ps.	10,640		Ps.	9,190		Ps.	9,013
Net interest expense			17,041			14,443			12,153
Reductions and terminations			—			—			—
Components of defined benefit costs recognized in profit or loss			27,681			23,633			21,166
Remeasurement on the net defined benefit liability:
Actuarial gains and losses arising from changes in financial and demographic assumptions			13,893			5,499			6,105
Actuarial gains and losses arising from experience adjustments			2,916			5,124			(3,916)
Components of defined benefit costs recognized in other comprehensive income			16,809			10,623			2,189
Total		Ps.	44,490		Ps.	34,256		Ps.	23,355

The current service cost and the net interest expense are included in the employee benefits expense in the consolidated statement of income and in other comprehensive income.

The remeasurement of the net defined benefit liability is included in other comprehensive income.

The amount included in the consolidated statement of financial position arising from the Company’s obligation in respect of its defined benefit plans is as follows:


		December 31,
		2025			2024			2023
Present value of defined benefit obligations		Ps.	196,768		Ps.	165,279		Ps.	143,058

Movements in the present value of the defined benefit obligation in the current year are as follows:


		December 31,
		2025			2024			2023
Present value of defined benefit obligation as of January 1,		Ps.	165,279		Ps.	143,058		Ps.	121,477
Current service cost			10,640			9,190			9,013
Interest cost			17,041			14,443			12,153
Reductions and terminations			—			—			—
Remeasurement (gains)/losses:
Actuarial gains and losses arising from changes in financial and demographic assumptions			13,893			5,499			6,105
Actuarial gains and losses arising from experience adjustments			2,916			5,124			(3,916)
Benefits paid			(13,001)			(12,035)			(1,774)
Present value of defined benefit obligation		Ps.	196,768		Ps.	165,279		Ps.	143,058

Significant actuarial assumptions for the determination of the defined obligation are discount rate, expected salary increase and mortality. The sensitivity analyses below have been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period, while holding all other assumptions constant.

The sensitivity analysis presented above may not be representative of the actual change in the defined benefit obligation as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated.

Furthermore, in presenting the above sensitivity analysis, the present value of the defined benefit obligation has been calculated using the projected unit credit method at the end of the reporting period, which is the same as that applied in calculating the defined benefit obligation liability recognized in the consolidated statement of financial position.

There was no change in the methods and assumptions used in preparing the sensitivity analysis from prior years.

There was no change in the process followed by the Company to manage its risks from prior periods.

The average duration period of the benefit obligation as of December 31, 2025, is 13.37 years (2024: 14.05 years and 2023: 14.26 years).

Expected cash flows from termination benefits and seniority premium benefits for the next 10 years are as follows:


		Pensions			Seniority premium
Year		plan			benefits			Total
2026		Ps.	13,566		Ps.	3,835		Ps.	17,401
2027			3,191			3,693			6,884
2028			10,670			4,018			14,688
