Insights

Corporate governance analyst

Routine insider sales disclosed; neutral governance signal.

WTTR reported insider transactions by CEO/Director John D. Schmitz via multiple trusts over three days, with weighted‑average prices noted and execution ranges provided in footnotes. These are standard open‑market sales and include post‑trade beneficial ownership balances for each account.

The filing lists both direct and indirect holdings across trusts and entities, clarifying ownership after the reported sales. Actual market impact depends on holder activity and float; the filing does not indicate strategic change.

Key anchors are the reported share counts per transaction and the Family Trust’s post‑transaction balance of 1,746,548 shares; subsequent filings would update any further changes.
