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.

Quarter flow (concentrated managers)

Change in managers (4 → 4): 0 opened · 0 exited = 0

Net flow in the quarter: −$18.7M (−246 K shares) · bought $2.7M and sold $21.4MShares 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, 3 held it last quarter (the chart point); with today's set, 4 (the base for the change).

Largest holders of LNT (all 13F filers)

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 reported by the 885 13F filers as of Jun 30, 2026, divided by the shares outstanding on the cover of the company's latest report (Mar 31, 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.

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.
