Shares held (13F)
194,110,962
% of shares outstanding suppressed: the summed institutional 13F holdings (194,110,962) exceed the latest reported shares-outstanding count (48,258,111) by more than securities-lending double counting can explain (FINRA short interest 470,339 shares at 2026-04-30), so the share count is stale or wrong (common for annual 20-F foreign private issuers after a share issuance) and a percentage would be fabricated. Holder share counts are shown as filed.

Rows rank by the value each filer reported — 13F filers price their own positions, so a holder with fewer shares can rank just above one with more.
