Material information

CTT - Correios de Portugal, S.A. ("CTT" or "Company") hereby informs that the new Plan of Social Action – Plano de Ação Social ("PAS") will come into force on 1January 2024. This new plan, which will replace the former Regulamento de Obras Sociais, will govern the healthcare benefits plan of all employees and retirees of CTT and of their families, as applicable.

Moreover, CTT estimates that as at 31 December 2023 the gross present value of the responsibilities supported by CTT in relation to this plan will be €154.2m (€190.4m as at 31 December 2022). The difference is primarily explained by changes (i) in the financial assumptions, including the new conditions defined in the PAS, inflation expectations and the outlook for the evolution of healthcare costs, and (ii) in the demographic assumptions.

CTT believes that the conditions defined in the new PAS will further enhance the sustainability of the healthcare benefits provided to CTT's employees and retirees, and to their families.

This information to the market and the general public is made under the terms and for the purposes of article 29-Q of the Portuguese Securities Code and other legislation in force in Portugal. It is also available on CTT website at:
