Insights

Equity ownership & governance analyst

CEO’s pre-planned sale of 1,500 shares looks routine and modest.

Plexus Corp’s President & CEO Todd P. Kelsey executed two open-market sales totaling 1,500 common shares on May 20, 2026, at weighted average prices near $252–$253 per share. These transactions are coded as standard open-market sales.

A footnote states the trades were made pursuant to a Rule 10b5-1 plan adopted on November 20, 2025, indicating they were pre-scheduled rather than opportunistic. The filing also shows the CEO retaining a substantially larger direct share position after the transactions.

Given the small size relative to his remaining holdings and the pre-planned nature, this activity typically signals routine diversification or liquidity rather than a change in view on Plexus Corp’s prospects. Subsequent company filings will continue to update any further insider trading activity.

4 terms

Rule 10b5-1 plan regulatory

"Shares were sold pursuant to a Rule 10b5-1 plan adopted on November 20, 2025."

A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.

open-market sale financial

"transaction_action": "open-market sale""

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

weighted average sale price financial

"The reported price reflects the weighted average sale price."

Form 4 regulatory

"INSIDER FILING DATA (Form 4):"

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
