In accordance with Peruvian legislation, the Group is obliged to pay its employees profit sharing of between 8% and 10% of annual taxable income. Distributions to employees under the plan are based 50% on the number of days that each employee worked during the preceding year and 50% on proportionate annual salary levels.

The workers’ profit sharing is recognized in the following line items:

In 2011, the Group implemented a compensation plan for its key management. This long-term benefit is payable in cash, based on the salary of each officer and depends on the years of service of each officer in the Group. According to the latest plan update, the executive would receive the equivalent of an annual salary for each year of service beginning to accrue from 2019. This benefit accrues and accumulates for each officer and is payable in two installments: the first payment will be made on the sixth year after the creation of this bonus plan, and the last payment at the end of the ninth year from the creation of the plan. If the executive decides to voluntarily leave the Group before a scheduled distribution, they will not receive this compensation. The Group used the Projected Unit Credit Method to determine the present value of this deferred obligation and the related current deferred cost, considering the expected increases in salary base and the corresponding current government bond discount rate (risk-free rate).

As of December 31, 2024 and 2023, it corresponds to the provision for the future costs of rehabilitating the quarries exploited in Company’s operations. The provision has been created based on studies made by internal specialists. Management believes that the assumptions used, based on current economic environment, are a reasonable basis upon which to estimate the future liability. These estimates are reviewed regularly to consider any material change to the assumptions. However, actual quarry rehabilitation costs will ultimately depend upon future market prices for the necessary decommissioning works required to reflect future economic conditions.

Future cash flows have been estimated based on financial budgets approved by Management. The range of the risk-free discount rate in dollars used in the calculation of the provision as of December 31, 2024 was from 0.53 to 4.86 percent and the risk-free discount rate in dollars used in the calculation of the provision as of December 31, 2023 was from 0.52 to 4.20 percent.

Management expects to incur a significant part of this obligation in the medium and long-term. The Group estimates that this liability is sufficient according to the current environmental protection laws approved by the Ministry of Energy and Mines of Peru.
