Issue of new VINCI shares, reserved for group employees in France in the context of its savings plan*

The Combined General Meeting of Shareholders of 17 April 2025, in its twenty-fifth resolution, delegated to the Board of Directors its authority to carry out capital increases reserved for employees for a period of 26 months expiring on 16 June 2027.

In this context, it defined the method for determining the issue price of the new shares.

During its meeting of 18 June 2025, the VINCI Board of Directors set the terms of a capital increase reserved for the Group's France-based employees, this operation falling within the delegation of authority received from the shareholders' meeting.

The maximum number of shares that may be issued and the total amount of the issue will depend on the level of employee subscriptions to the units to be issued by the "Castor Relais 2025/3" mutual fund which will be recorded at the end of the subscription period which will run from 1 September to 31 December 2025.

The issue price of the new shares is equal to 95% of the average opening prices of VINCI shares listed on the regulated market of Euronext Paris SA during the 20 trading days preceding 18 June 2025, i.e. €120.88 per new share to be issued.

The "Castor" mutual fund is an employee savings and employee shareholding fund invested in VINCI shares. It is one of the main instruments for implementing the VINCI Group's savings plan in France.

^• Employees will subscribe for this issue, which is reserved for them, through a temporary mutual fund initially and momentarily invested in monetary securities known as "Castor Relais 2025/3" and classified as a euro monetary mutual fund. This mutual fund received the approval of the AMF on 12 June 2025, under no. FCE 2025 0272. It will collect employees' cash payments intended to subscribe for the units that it issues. At the end of the subscription period open to employees, this temporary mutual fund will subscribe to VINCI shares to be issued in accordance with the total amount of payments it has collected and will then be absorbed by the "Castor" mutual fund as from 10 February 2026. The AMF approved such a merger in advance on 24 June 2025 (AMF file no. SCIFU015328).
