The Annual General Meeting on May 22, 2025, of Sinch decided to authorize the company's Board to decide on the acquisition of own shares. According to the mandate from the Annual General Meeting, the Board has the right to acquire shares so that the company, after the acquisition, holds a total of no more than ten percent of all shares in the company at any given time.

The Board has previously launched a buyback program as announced on July 21, 2025. Under this program, a total of 79,611,294 shares were acquired. Following a resolution by the Extraordinary General Meeting on February 19, 2026, 74,211,294 of these shares were cancelled on February 20, 2026.

The Board has decided to utilize this authorization again and intends to repurchase shares to reach a total holding of ten percent of the total number of shares at each given time in the company. The purpose of continuing the acquisition of own shares is to adapt the company's capital and share structure to contribute to increased shareholder value. Repurchases will be carried out continuously from the date of this announcement until the Annual General Meeting 2026.

The total number of shares issued by Sinch is currently 770,724,673 shares. Sinch's holding of own shares as of today's date amounts to 5,400,000 shares. Accordingly, based on the total number of shares issued by Sinch as of this day, a maximum of 71,672,467 additional shares may be repurchased.

Acquisitions will take place on Nasdaq Stockholm and will be communicated in accordance with Nasdaq Stockholm's Rule book for Issuers. Repurchases may only take place at a price per share within the prevailing price interval on Nasdaq Stockholm, meaning the interval between the highest bid price and the lowest ask price published continuously by Nasdaq Stockholm. The Board's decision means that the acquisition of shares can be carried out through block trades.

No acquisitions will be made during the 30-day period preceding the publication of an interim financial report.
