Δ vs 2025-Q4 · % of shares outstanding suppressed: the summed institutional 13F holdings (65,498,354) exceed the cover-page shares-outstanding count for this quarter (56,331,110, as of 2026-02-20) by more than securities-lending double counting can explain (FINRA short interest 5,695,614 shares at 2026-05-15), 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.ⓘ
