2. F2. The previous Form 4 for the Reporting Person, filed on August 17, 2026, inadvertently misstated the vesting schedule for the RSUs granted to the Reporting Person on August 14, 2026. That filing incorrectly stated that such RSUs will vest on August 14, 2027, subject to the Reporting Person's continued service through the vesting date. The RSUs will instead vest in equal annual installments over a three year period on each of the succeeding three anniversaries of the grant date, subject to the Reporting Person's continued service through each vesting date. This footnote corrects such disclosure.

Ordinary Shares financial

"The Ordinary Shares were sold in a single transaction at a price"

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.

RSUs financial

"misstated the vesting schedule for the RSUs granted to the Reporting"

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

vesting schedule financial

"inadvertently misstated the vesting schedule for the RSUs granted"

A vesting schedule is a timeline that determines when someone gains full ownership of certain benefits, such as company stock or retirement contributions. Think of it like earning the right to own a gift gradually over time, rather than receiving it all at once. It matters to investors because it affects when they can fully access or sell these benefits, influencing their financial planning and decision-making.

Rule 10b5-1 trading plan regulatory

"The Rule 10b5-1 checkbox is not marked for these transactions"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

Explanation of Responses:

1. The Ordinary Shares were sold in a single transaction at a price between $35.11 and $35.12.

2. The previous Form 4 for the Reporting Person, filed on August 17, 2026, inadvertently misstated the vesting schedule for the RSUs granted to the Reporting Person on August 14, 2026. That filing incorrectly stated that such RSUs will vest on August 14, 2027, subject to the Reporting Person's continued service through the vesting date. The RSUs will instead vest in equal annual installments over a three year period on each of the succeeding three anniversaries of the grant date, subject to the Reporting Person's continued service through each vesting date. This footnote corrects such disclosure.
