restricted stock unit financial
"Represents shares of common stock underlying a time-based restricted stock unit award"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
open-market transaction financial
"Represents shares purchased in an open-market transaction"
An open-market transaction is a buy or sell of a company's shares or other securities conducted on a public exchange at the current market price, rather than through a private agreement. Investors watch these trades because they change the number of shares available and can move the price immediately—similar to how a large purchase at a busy store can raise demand and affect the checkout price—so such activity can signal market sentiment and alter ownership stakes.
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.
vesting financial
"1/3rd of the shares subject to the RSU award shall vest on each"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
exercise price financial
"The option will vest over a three year period, with 1/3rd of the option vesting"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
