"All transactions reported on this Form 4 were effected pursuant to a Rule 10b5-1 trading plan established by Mr. Talwalkar on May 12, 2025."

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.

"security_title": "Employee Stock Option (right to buy)""

expiration date financial

"This option has an expiration date of May 23, 2026."

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
