Stock Option financial

"The new stock options have an exercise price of $132.06 per share"

A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.

Class A Common Stock financial

"Luc Walter directly owns 353,742 shares of Amphenol Class A Common Stock"

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.

Grant, award, or other acquisition financial

"The transaction code A indicates a grant, award, or other acquisition of derivative securities"

Date Exercisable financial

"Date Exercisable: 20% per year over a five year period"
