Insights

Lumentum director executes pre-planned sale of 11,951 shares under a Rule 10b5-1 plan.

Director Brian Lillie sold 11,951 shares of Lumentum Holdings common stock in a series of open-market trades on May 11, 2026. Reported sale prices span several tight ranges from about $955.00 to $1,004.00 per share, reflecting multiple small executions.

The filing specifies these sales occurred pursuant to a Rule 10b5-1 trading plan adopted on February 6, 2026, indicating they were pre-arranged rather than opportunistic. After the transactions, Lillie holds 24,441 shares, so he retains a meaningful equity position despite the net-sell activity.

Rule 10b5-1 trading plan regulatory
"These shares were sold pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person"
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
open-market sale financial
"transaction_action: "open-market sale" for each non-derivative transaction"
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 price reported above reflects the weighted average sale price"
Form 4 regulatory
"within the ranges set forth in footnotes (2) through (23) to this 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.
