FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What did FDMT’s Chief Legal Officer report in this Form 4 filing?

The filing reports a grant of 217,000 stock options to Chief Legal Officer Scott Bizily. These options are part of equity compensation and do not represent an open-market share purchase or sale. They provide the right to buy common stock at a set price.

What is the exercise price and term of the new FDMT stock options?

The granted options have an exercise price of $9.88 per share and expire on March 24, 2036. This means the holder can buy common shares at $9.88 any time after vesting and before expiration, subject to remaining employed or serving the company.

How do the 4D Molecular (FDMT) options granted to the CLO vest?

The options vest in 48 equal monthly installments starting on March 25, 2026. Each month, 1/48th of the 217,000 underlying shares becomes exercisable, so the award is fully vested on the fourth anniversary, if the recipient continues as a service provider.

Is the FDMT Form 4 transaction a stock purchase or sale on the market?

No, the Form 4 reflects a compensation-related option grant, not an open-market stock purchase or sale. The reporting person received derivative securities (options) at no cash cost, which may later be exercised to acquire common shares if conditions are met.

How many FDMT shares underlie the Chief Legal Officer’s new option grant?

The award covers 217,000 underlying shares of common stock. These shares are not issued immediately; they become purchasable over time as the options vest, assuming the Chief Legal Officer continues providing services to 4D Molecular Therapeutics throughout the vesting period.
