Insights

Securities Analyst

TL;DR: Insider sold 3,597 WAB shares under a 10b5-1 plan; transparency provided via weighted-average prices and price ranges.

These sales are disclosed clearly and the filing identifies the transactions as covered by a 10b5-1 trading plan, which typically indicates pre-arranged disposition rather than opportunistic trading. The Form 4 lists individual sale blocks with weighted-average prices and ranges, and shows the insiders remaining direct holdings at 134,931 shares. From a market-impact perspective, the volumes reported here are modest relative to typical public-company free float sizes, but the filing appropriately meets reporting requirements and provides the specific pricing ranges for auditability.

Corporate Governance Expert

TL;DR: Sales executed under an indicated 10b5-1 plan, with full footnote disclosure of price ranges and POA signature.

The form includes explanatory footnotes describing weighted-average prices and commits to provide detailed trade-by-trade information on request. The signature by a power of attorney is indicated.
