5 terms

restricted shares financial

"Represents restricted shares of common stock of ChronoScale Corporation"

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.

Grant Date financial

"granted on May 14, 2026 (the "Grant Date") which vest as follows"

The grant date is the day a company formally gives an employee or contractor the right to receive stock-based compensation, such as stock options or restricted shares. It matters to investors because it fixes key terms—like the price, the start of the ownership clock, and when the award will affect the company’s financial statements and share count—so it can influence dilution, reported expenses, and potential future selling pressure.

vesting financial

"which vest as follows: (i) 100,000 restricted shares will vest"

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.

continuous service financial

"subject to the Reporting Person's continuous service with the Issuer"

accelerated vesting financial

"subject to adjustment or accelerated vesting upon certain conditions"

A contract feature that makes stock awards, options, or restricted shares become owned or exercisable earlier than the original schedule. It shortens or cancels the waiting period so recipients can sell, transfer, or exercise their equity sooner — think of a timed lock that is unlocked ahead of schedule. It matters to investors because it changes when shares enter the market, who controls them, and how much dilution or ownership concentration happens.
