NORGES BANK, Point72 Asset Management, L.P., Bridgewater Associates, LP hold a position with no prior filing to compare against, so their change is unknown rather than zero — and they are left out of the totals above.
From 13F filings, which cover institutions managing over $100m and are filed up to 45 days after the quarter ends — so this is a considered position, not a live one, and it is not the whole shareholder register.
What the company actually paid out and bought back, as reported — the record behind any yield figure.
Ownership percentages are a vendor aggregate, not a filing — unlike everything else on this page.
ATMOS ENERGY CORP files under SIC 4924 — all 7 natural gas distribution companies compared on assets and F-score.
Where dealer gamma sat in ATO’s option chain after the close on 2026-09-01, aggregated from the full chain. This is a once-a-day snapshot, not a live read — 62 contracts.
Computed from the listed option chain by my own aggregation, once, after the close — it describes where positioning sat that evening and does not update through the next session. The version that rebuilds per strike while the market is open is the intraday gamma product. Not investment advice.
The structure map above is the Corporate Blueprint, and in the desktop it is interactive — click any entity to re-centre the map on it and walk the ownership chain. It sits alongside the screener, the scorecard and the filings lab on one desk, on your machine.
Sourced from SEC EDGAR primary filings. Figures are as reported by the company and are not investment advice. Scores are standard published screens computed from those filings; every input is shown above so you can check the arithmetic.
