13F percentages divide the shares each institution reports by the shares outstanding on the cover of the company's latest report before the quarter end (May 8, 2026). Entities of the same group file separately and are not added up. We hold 13D and 13G filings made since Dec 23, 2024: a holder above 5% that has not filed since then does not appear here.

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): 65.8% of the shares · top 10: 54.4% · in index firms: 7.1% of the institutional total
Q2 2026: 65.8%
Shares reported by the 60 13F filers as of Jun 30, 2026, divided by the shares outstanding on the cover of the company's latest report (May 8, 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.

This company's sector comes from its SIC code, unreviewed, or has too few comparable companies: we do not compare it with its sector.
Figures from the statements the company filed with the SEC (10-K, 10-Q). Free cash flow = operating cash flow − capital expenditures; empty if the company does not report capex. “Quality vs sector”: 0 to 100, the average of its percentiles in ROE, operating margin, free-cash-flow margin, revenue and earnings growth and net debt / EBITDA (at least 3 needed) against companies in its sector above $300M. How each figure is calculated

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
- Operating cash flow ÷ net income (12 months)
- no datanot calculated with negative net income
- Debt due within 12 months
- no data
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.
Insiders (Form 4)
10% owners who bought (6 m): 0
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.
