Quarter flow (concentrated managers)
Change in managers (13 → 10): 0 opened · 3 exited = −3
Net flow in the quarter: −$74.2M (−2.3 M shares) · bought $17.8M and sold $92.1MShares concentrated managers added minus those they cut, valued at the 13F quarter-end implied price, not each trade's price. It is a different measure from the change in managers: the two can have opposite signs.
The set of concentrated managers changed between quarters: with the set as it was then, 12 held it last quarter (the chart point); with today's set, 13 (the base for the change).

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): 116.6% of the shares: above 100% (securities lending or double reporting) · top 10: 77.2% · in index firms: 13.3% of the institutional total
Q2 2026: 116.6%
Shares reported by the 168 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.

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
Shares outstanding: buybacks and dilution
2025: 59.6 M
There is a jump that may be an undetected split: we do not show the changes.
- Buybacks (FY 2025)
- no data
- Share issuance
- no data
- Stock-based compensation
- $28.0M
- Dividends paid
- no data
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
- Interest coverage (operating income ÷ interest)
- no data
- 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.
