EQS-CMS: IONOS Group SE: Release of a capital market information

Acquisition of treasury shares

The share buyback program announced by IONOS Group SE in the ad hoc announcement of 21 January 2025 will be carried out from 27 January 2025. In the period until 31 December 2025 at the latest, up to 1,500,000 of the company's own shares are to be acquired exclusively via the stock exchange (XETRA trading or a corresponding successor system). The volume of the buyback program amounts to a total of up to EUR 40 million (excluding associated costs).

In a period starting 5 trading days prior to an Annual General Meeting until the end of 3 trading days after an Annual General Meeting, no shares will be bought back.

With the approval of the Supervisory Board, the Management Board is thus making use of the authorization issued by the Extraordinary Shareholder Meeting of IONOS Group SE on 26 January 2023 to acquire treasury shares in accordance with Section 71 (1) No. 8 of the German Stock Corporation Act (AktG).

The buyback will be used, among other things, to fulfil obligations from employee share option programs, but can in principle be used for all purposes specified in the authorization of the Annual General Meeting.

The company has commissioned a bank with the buyback. The bank makes its decisions on the timing of the acquisition of the shares independently of and uninfluenced by the company. The company's right to terminate the mandate with the bank prematurely in accordance with the legal requirements to be observed and/or to transfer the mandate to one or more other banks remains unaffected.

The share buyback can be suspended, interrupted and, if necessary, resumed at any time in accordance with the legal requirements to be observed.

The buyback is to be carried out exclusively via the stock exchange in electronic trading on the Frankfurt Stock Exchange (Xetra) and in accordance with the authorization granted by the Extraordinary Shareholder Meeting of the company on 26 January 2023. The purchase price per repurchased share (excluding associated costs) may not be more than 10% higher or lower than the arithmetic mean of the prices of the IONOS Group SE shares in the closing auction in the XETRA trading system (or a corresponding successor system) on the Frankfurt Stock Exchange during the last three trading days prior to the record date, whereby the record date is the day on which the obligation to purchase is entered into.

In addition, the Bank has undertaken to execute the buyback in accordance with the trading conditions set out in Article 3 of Commission Delegated Regulation (EU) No. 2016/1052 of 8 March 2016 ("Del. Regulation"). In accordance with the Del. Regulation, no purchase price may be paid that is higher than that of the last independent trade or the highest independent bid at the time of the purchase, in each case on the trading venue on which the purchase takes place. The higher of the two values is decisive. In accordance with the Del. Regulation, no more than 25% of the average daily share turnover on the trading venue on which the purchase is made may be acquired on any one day. The average share turnover is calculated from the average daily trading volume of the 20 trading days prior to the specific purchase date.

The transactions will be disclosed in an aggregated form in accordance with the requirements of Art. 2 (3) Del. Regulation no later than the end of the seventh trading day after their execution. Furthermore, IONOS Group SE will publish the transactions on its website at http://www.ionos-group.com/investor-relations/share/share-buyback.html and ensure that the information remains publicly accessible for at least five years from the date of disclosure.
