Shares held (13F)

19,646,125

Reporting holders

306

% of shares outstanding suppressed: the summed institutional 13F holdings (19,646,125) exceed the latest reported shares-outstanding count (17,969,641) by more than securities-lending double counting can explain (FINRA short interest 777,196 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.

† a filer this large appearing as NEW usually reflects a renamed or succeeded filing entity (the old name stops filing the same quarter) — not a brand-new position.

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.

Shares reported each quarter by the largest current holders. Green = added vs the prior filing, red = trimmed, grey = roughly held; a dash is a quarter with no 13F on file (a gap is skipped, not read as an exit). 13F is filed up to 45 days after quarter-end. Up to 40 quarters (10 years) available — use the selector above.

Institutional footprint by quarter

Line breaks are honest gaps — quarters with no 13F record, or a suppressed % — never interpolated. % of shares outstanding uses today's share count for every quarter (the only count stored).

† a filer this large appearing as NEW usually reflects a renamed or succeeded filing entity (the old name stops filing the same quarter) — not a brand-new position.

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.
