Antin: sale of 5 million shares at €7.18, free float rises to 17.5%

A sale that brings free float to 17.5% of capital

Antin Infrastructure Partners announced on 15 September 2026 that it had been informed of a share placement expanding its free float for the second time since its initial public offering in September 2021, subject to settlement and delivery of the transaction. The sale concerned 5.0 million ordinary shares, representing approximately 2.8% of capital, at a price of €7.18 per share.

Following this transaction, Antin's free float increased by approximately 2.9 million shares, rising from 15.8% to 17.5% of outstanding capital. Shares sold by former partners represented approximately 65% of the sale.

Purchases by executives and by Antin, new lock-up period

Certain members of the executive committee, including Alain Rauscher, chief executive officer, acquired approximately 1.4 million shares at the offering price. Antin in turn acquired approximately 0.7 million of its own shares at the offering price, as part of its share buyback programme authorised by the general meeting of 10 June 2026.

The sale followed the second post-IPO lock-up expiry, during which 25% of shares held by the partner concert were released. The sellers and executive committee members who participated in the transaction agreed to an additional 90-day lock-up period, subject to certain customary exceptions. The transaction was conducted through an accelerated private placement to qualified investors, with BNP Paribas acting as global coordinator and sole bookrunner.
