What is the total expected size and timing of the share repurchase and how does it compare to the company's historical buyback levels?

Size & timing: STMicroelectronics has confirmed that its current common‑share repurchase programme is authorised for up to €2.5 billion and is slated to run through 2026, with the bulk of the purchases expected to be completed by the end of 2025. Management indicated that the first tranche – roughly €500‑€600 m – will be executed in the next 12 months, with subsequent quarterly buy‑backs paced to the share‑price level and cash‑flow generation.

Historical comparison: This authorisation is a step‑up from the company’s most recent buy‑back cycle (2020‑2022), which capped at €1.5 billion and was largely finished by mid‑2023. In other words, the new programme is about 65 % larger and extends the repurchase horizon by two years, signalling stronger balance‑sheet flexibility and confidence in the stock’s valuation relative to its longer‑term earnings outlook.

Trading implications: The sizeable, near‑term €500‑€600 m tranche provides a clear floor‑support catalyst, especially if the stock trades below its 200‑day moving average (~€30). Expect modest price appreciation on the announcement and a potential “buy‑the‑dip” opportunity as the first tranche rolls out, particularly in the face of any short‑term weakness in the semiconductor sector. Conversely, if the price climbs well above €35, the programme may be throttled, limiting upside; thus, watch for quarterly filing updates to gauge execution speed and adjust position sizing accordingly.
