Restricted Stock Units financial

"Each restricted stock unit ("RSU") represents a contingent right to receive one share"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax withholding obligations financial

"represents shares sold by the Reporting Person to cover tax withholding obligations"

Liquidity Event financial

"vests as Common Stock on a one-for-one basis immediately prior to the date of a Liquidity Event"

A liquidity event is a transaction that converts ownership in a privately held or illiquid asset into cash or a marketable security, such as a sale, merger, public stock offering, or buyout. It matters to investors because it provides a clear way to realize returns or recover capital—think of it as turning a house into a cash sale—so the timing, price and structure of the event determine how much money stakeholders actually receive.

Employee Stock Option financial

"Employee Stock Option (right to buy) ... vests in three equal annual installments"

An employee stock option is a promise that lets a worker buy company shares later at a predetermined price, often after they stay for a certain period or meet performance goals — think of it like a coupon that locks in today's price for a future purchase. It matters to investors because options align employees’ incentives with company performance, can increase the number of shares outstanding (dilution) when exercised, and represent a compensation cost that affects reported profits and shareholder value.

vesting financial

"The RSUs vest in three equal annual installments beginning on April 15, 2026."

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.
