The 10 13F filers with the most shares as of Jun 30, 2026, whatever their type (index firms usually come first). “Change”: shares added or cut versus the previous quarter, split-adjusted; “no data” = there is no comparable portfolio for the previous quarter (no filing, or a filing with its holdings under confidential treatment). “% of the company” only where shares outstanding are up to date. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. With a free account: the top 25, the largest buyers and the largest sellers.
Held by institutions (13F)
Institutions (13F): 57.1% of the shares · top 10: 29.5%
Q2 2026: 57.1%
Shares reported by the 43 13F filers as of Jun 30, 2026, divided by the shares outstanding on the cover of the company's latest report (Apr 14, 2026). It is not all institutional ownership: only managers above $100M file a 13F, and it excludes short positions. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. We only publish it where the figure is credible: not for ADRs, companies with more than one share class or stale shares-outstanding data.
Fundamentals
Balance sheet only, for now. LEGO has not yet filed its first annual report (10-K) with the SEC, so there are no 12-month figures (revenue, margins, earnings and cash flow). We show the balance sheet from its latest filing; once the 12-month figures are available, this section fills in automatically.

Balance sheet figures the company filed with the SEC (10-Q or 10-K), in dollars. Net debt = total debt − cash − investments; when negative, the company has more cash than debt (net cash). How each figure is calculated
Insiders (Form 4)
Open-market purchases, excluding 10b5-1 plans. Officers and directors only; joint filers of the same purchase count as one. 10% owners with no role are shown separately. 0 = nobody bought; “no data” = we do not have its Form 4 filings.

Above 5% (13D/13G)
Disclosed stakes, with their amendments. A filing is not always a purchase: there are also reductions and changes of filing entity.
This list may be incomplete: we hold 13D and 13G filings made since Dec 23, 2024. A holder above 5% that has not filed anything since then is not shown here.

Alert items the company itself flagged in its 8-K filings with the SEC, most serious first. It is the form's label, with no interpretation from us: Item 5.02 covers routine appointments as well as a chief executive's departure; open the filing. The quoted headline is the original press release's.
