Insights

Financial Analyst

TL;DR: Routine director sale of 500 shares under a Rule 10b5-1 plan; remaining direct holding 8,865 shares.

The transaction is a non-derivative disposition of 500 Plexus shares at $139 each executed on 08/29/2025 and reported on Form 4. Because the sale was made pursuant to a Rule 10b5-1 plan adopted on 02/28/2024, it represents a prearranged sale framework rather than an ad hoc trading decision. The remaining direct beneficial ownership is reported as 8,865 shares. This disclosure provides transparent information on insider liquidity but does not include any new operational or financial data about the company.

Corporate Governance Expert

TL;DR: Insiders used an established 10b5-1 plan to execute a modest sale; filing appears procedurally compliant.
