8.1.2 Changes in the share capital since the incorporation of the Company

The Company was formed on 18 June 2021, with an initial share capital of €40,000 divided into 10,000 shares with a nominal value of €4, with €160,000 issuance premium (corresponding to a subscription price of €20 per share). On the pricing date of the IPO i.e. 23 September 2021 (the “ Pricing Date ”), pursuant to contribution agreements, the Partner Shareholders first contributed to the Company all of the shares of AIP UK that they held in exchange for newly issued shares of the Company and then contributed to the Company all of the shares of AIP SAS that they held, also in exchange for newly issued shares of the Company (the “ Contributions ”). Following the Contributions, the Company took the control of AIP SAS and AIP UK and became the parent company of a group of companies comprising the two entities (i.e. AIP SAS and AIP UK).

In order to allow the full release of the capital increases resulting from the Contributions, on 30 July 2021, the extraordinary shareholders' meeting authorised a share capital reduction by way of reduction in the nominal value of the Company’s shares (from €4 to €0.01). The share capital reduction was completed on the date of completion of the Contributions immediately before such Contributions. On the Pricing Date, the Board of Directors acknowledged the capital increase resulting from the Contributions for a nominal amount of €966,358.54. In addition, a total of 16,770,832 new shares with a nominal value of €0.01 were issued on 30 September 2021 in the context of the IPO (including the exercise of the over-allotment option) and a total of 291,630 new shares with a nominal value of €0.01were issued on October 14, 2021 in the context of the Employee Offering.
