FLAGSTAR BANK, NATIONAL ASSOCIATION is a bank, scored by a separate financial-sector model — not the operating Moat Score you’ll see on other companies. A bank or insurer is a balance-sheet business the margin-and-ROIC lens doesn’t fit, so it’s read through the components below instead. The two models are calibrated differently and are not comparable: a financial-sector score is never ranked against, sorted with, or averaged into an operating Moat Score. How the models work.
Insider activity
Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”
These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.
This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.
Records still being gathered — partial as of retrieval Sep 18, 2026.
121 filings were skipped because the SEC primary document returned 404; the omission is disclosed and aggregates are withheld.
Trailing-12-month totals and the 90-day cluster result are withheld because this issuer walk is incomplete.
No reported Form 4 rows were captured for FLG; the incomplete walk cannot establish zero activity, zero counts, or a negative cluster result.
A filing source-event date will appear when a Form 4 row is captured.

Append-only — readings are added, never rewritten. Only readings on the same methodology version (moat-index-financials@1.0.0) are comparable; a change across versions is a scoring change, not a company event.
Scored from primary SEC filings via the public financial-sector methodology. Educational only — not a recommendation to buy or sell FLG. See the disclaimer.
