weighted average price financial

"The price reported in Column 4 is a weighted average price."

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.

restricted ordinary shares financial

"Consists of (1) 3,363 ordinary shares, (2) 29 restricted ordinary shares..."

Restricted ordinary shares are common stock that cannot be sold or transferred until certain conditions are met—such as a time period passing, performance targets being reached, or regulatory approvals—often issued to employees, founders, or early investors. They matter because those restrictions delay when the shares can enter the market, affecting the future supply of shares, potential dilution and company valuation; think of them as goods locked in a warehouse until release conditions are satisfied.

vest in equal installments financial

"restricted ordinary shares that vest in equal installments on a monthly basis..."

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.
