Filing: Samsung sold ~3.55M ASML shares from April to June 2023, more than halving its holding from 1.6% to 0.7%, or 2.75M shares, and reportedly raising ~$2.2B

Context & Ripple Effects
Samsung’s April–June sale was the first large reduction in an ASML position that had been a strategic financial link between a major chipmaker and a key equipment supplier. The subsequent September share sale completed Samsung’s exit from ASML, making this filing the opening stage of a full divestment rather than an isolated portfolio adjustment.
The sale also sits against later evidence of ASML’s deepening commercial exposure to South Korea: the country became ASML’s largest market in Q1 2026. That makes the separation of equity ownership distinct from the continuing importance of the supplier-customer relationship.
First-order effects
- Samsung converts roughly $2.2B of ASML stock into cash and reduces its holding from about 1.6% to 0.7%, leaving it with less direct financial exposure to ASML’s share price.
- ASML loses a sizable Samsung shareholding; the reported sale was followed by a more than 7% decline in ASML shares, underscoring the near-term market impact of the disclosed supply of stock.
Second-order effects
- The reduced position gives Samsung greater flexibility to direct capital toward its own chipmaking priorities, while ASML’s investor base becomes less anchored by one major equipment customer.
- The later disposal of Samsung’s remaining ASML stake indicates that observers and peers could no longer treat Samsung’s ownership as a durable strategic alignment, even as Samsung remained an important ASML customer.
Third-order effects
- If chipmakers increasingly favor operating investment, internal capital returns, or new technology areas over cross-holdings in suppliers, supplier-customer ties may be defined more by purchasing relationships than equity stakes.
- ASML’s later sales concentration in South Korea suggests a structural split is possible: commercial dependence on a regional chip ecosystem can grow even as individual customers reduce financial ownership.
The trend: The episode is part of a broader shift toward separating strategic supply-chain partnerships from minority equity ownership in semiconductor manufacturing.
