stock options financial

"The reporting person exercised 3,125 fully vested stock options at the exercise (strike) price of $6.59 per share."

Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.

Ordinary Shares financial

"All 3,125 Ordinary Shares acquired upon exercise of the options... were immediately sold at a price of $39.22 per share."

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

unvested options financial

"Following these transactions, the reporting person holds 9,375 unvested options which vest in installments of 3,125..."

vesting financial

"Unvested options which vest in installments of 3,125 on each of June 1, 2026, September 1, 2026, and December 1, 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.
