Rule 10b5-1 trading plan regulatory
"The sales reported in this Form 4 occurred automatically pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on May 29, 2025."
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.
weighted average price financial
"The price reported in Column 4 is a weighted average price. The shares were sold in multiple transactions..."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
beneficial ownership regulatory
"The Reporting Person disclaims beneficial ownership of these securities, except to the extent, if any, of his pecuniary interest therein..."
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
pecuniary interest financial
"The Reporting Person disclaims beneficial ownership of these securities, except to the extent, if any, of his pecuniary interest therein..."
open-market sale financial
"transaction_action: "open-market sale" and transaction_code_description: "Sale in open market or private 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.
