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.

Shares outstanding: buybacks and dilution

From the statements the company filed with the SEC (10-K). The change compares average diluted shares of each fiscal year, on today's basis: negative = it bought back more than it issued; positive = dilution. “No data” = the company does not report that item under a tag we can read; it does not mean zero.

Earnings quality and debt

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.

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.
