Review the entire collected insider disclosure history with a free account.
Full collected history is available here after sign-in, separate from the public 12-month window. It is not an exhaustive trading history.
The largest open-market transaction by reported value in the public window was an open-market purchase by Miebach Michael on Feb 25, 2026: $101,263.53, involving 434 shares. Reported price: $233.33.
0 public-window transactions explicitly indicate a 10b5-1 plan. A missing indication is not proof that a transaction was discretionary. Prices and values are shown only when reported; unavailable fields are not filled with zero.
Collected disclosures show 0 open-market purchases and 0 sales with transaction dates in the trailing 30 days ending Oct 15, 2026. Net reported purchase less sale value is $0.00. The latest collected disclosure data is as of Oct 9, 2026. These counts do not represent every insider action.
12 distinct insiders appear in collected disclosures for transaction dates in the trailing 30 days ending Oct 15, 2026. The latest collected Form 4 was filed on Oct 1, 2026. A filing date is not the transaction date.
This page shows 96 collected transactions dated in the trailing 12 months ending Oct 15, 2026. 0 older collected transactions are summarized outside this window and can be viewed here after sign-in. This is collected disclosure coverage, not exhaustive history; 10b5-1 plan status and derivative securities are labeled per record.
Insider data covers the trailing 12 months on public tables. Congressional tables cover all saved disclosures. Neither is an exhaustive history. Form 4 filing dates and congressional disclosure dates may differ from trade dates. Congressional amounts are ranges, not estimated dollar totals. Disclosure activity alone does not establish intent or predict returns.
