Woofun AI reports that SK Hynix has enforced a strict ceiling on the conversion of its Korean-listed shares into American Depositary Receipts, limiting the volume to 2.5% of total shares outstanding. A South Korean securities custody institution confirmed that the $26.5 billion in ADRs issued on July 10th has exhausted this allocation. Consequently, new conversions are suspended until current ADR holders reverse their positions to free up capacity. SK Hynix declined to provide further comment on the matter.
