Buyback completes as shares recover

The most recent company event was the completion of ASM's share buyback program on September 15, 2026, listed in the Euronext Amsterdam company announcements. The program provides a concrete capital-return signal, while the share price remains below the 52-week high of EUR 1,092.50 recorded in the available market history.

Market data show a sharp contrast between short-term pressure and the longer annual performance. ASM stock was EUR 500.40 on September 22, 2025, compared with EUR 826.00 on September 21, 2026, an increase of 65.07 percent over that one-year reference period.

Q3 date gives investors a checkpoint

ASM International's next scheduled reporting date is October 27, 2026, when the company is listed as due to publish third-quarter results. The latest available earnings-call reference is the Q2 2026 call held on July 29, 2026, so the October update will provide the next formal test of demand for semiconductor wafer-processing equipment.

Consensus data collected by Marketscreener show 19 analysts, an average target of EUR 1,125.89 and a spread of 45.92 percent above the latest listed closing price of EUR 771.60 in that dataset. The differing closing references underline the importance of using the same trading timestamp when comparing targets with market prices.

Stock stays below yearly peak

On September 21, 2026, the stock traded between EUR 824.40 and EUR 842.80 and recorded volume of 116,438 shares. Market capitalization was EUR 40.745 billion at that snapshot. The next investor checkpoint is therefore defined by the October reporting date and by whether operating figures support the valuation implied by the analyst consensus.
