Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

exercise price financial

"conversion_or_exercise_price: "14.3100""

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.

FAQ

What did Amylyx (AMLX) director George M. Milne Jr. receive in this Form 4?

George M. Milne Jr. received a grant of stock options for 24,372 shares of Amylyx common stock. These options are part of his director compensation and allow him to buy shares at a fixed exercise price if he remains in service until vesting.

What is the exercise price of the Amylyx (AMLX) stock options granted?

The granted stock options have an exercise price of $14.31 per share. This means Milne can purchase Amylyx common stock at $14.31 in the future, regardless of the market price, once the options have vested and before they expire.

When do the new Amylyx (AMLX) stock options vest for George M. Milne Jr.?

The options vest in full on the earlier of June 4, 2027 or the date of the next annual meeting. Vesting requires Milne’s continuous service to Amylyx through that date, aligning his compensation with ongoing board participation and company oversight.

When do the Amylyx (AMLX) director stock options granted in this filing expire?

These stock options expire on June 3, 2036. After that expiration date, Milne can no longer exercise them to purchase Amylyx common shares, even if they have vested, so any exercise must occur before that deadline.

How many Amylyx (AMLX) options does George M. Milne Jr. hold after this grant?

Following this transaction, Milne holds 24,372 stock options directly according to the filing. All of these options relate to Amylyx common stock and reflect his position from this grant, subject to future vesting and any later transactions.

Is this Amylyx (AMLX) Form 4 transaction a market purchase or sale of shares?

This transaction is a grant of stock options, not a market purchase or sale of existing shares. The Form 4 classifies it as a grant, award, or other acquisition, providing potential future ownership rather than immediate open-market trading activity.
