Insights

Capital Markets Analyst

ST repurchased 206,478 shares in the week of Nov 24-25, 2025, bringing treasury stock to 22,535,661 shares (~2.5%).

The company executed buybacks on 24-Nov-25 (121,609 shares at a weighted average price of EUR 19.1007) and 25-Nov-25 (84,869 shares at EUR 19.1830), for a period total of 206,478 shares and an aggregate cost of EUR 3,950,859.05. The disclosed purpose is to satisfy obligations under share option and other employee/allocation plans; the shares may be held in treasury or reused for other lawful purposes under the Market Abuse Regulation.

This action is a routine capital-management activity rather than a material corporate event: the period purchases equal ~0.02% of issued capital and leave total treasury holdings at ~2.5%. Key items to watch over the next quarters include any material change in the pace or scale of repurchases relative to disclosed programs, further disclosures of shares used to settle employee plans, and updates to the Program posted on the company website; short-term market impact is likely limited given the small size of these trades.
