Insights

Equity Capital Markets Analyst

STMicroelectronics executed a modest tranche of its buyback program, repurchasing 399,335 shares for 9,822,245.18.

The company bought 399,335 ordinary shares between October 06, 2025 and October 10, 2025 at a weighted average price of 24.5965 per share to meet obligations from employee and management share plans. These purchases were executed on Euronext Paris and increase the treasury stock to 19,647,653 shares, roughly 2.2% of issued capital.

Because the tranche equals about 0.04% of issued capital for the period, the immediate market impact is limited; the transaction mechanically reduces free float and supplies shares for option/award settlement. Watch ongoing disclosures for the total remaining authorization and any changes in the pace of repurchases over the next reporting periods to assess materiality; the disclosed figures here provide a clear baseline.
