FAQ

What does Linda Bain’s Form 3 for Autolus Therapeutics (AUTL) disclose?

The Form 3 discloses that director Linda Bain holds several stock options over Autolus Therapeutics American Depositary Shares. It lists each option’s exercise price, expiration date, and underlying share amount, providing a snapshot of her derivative equity position as of the reporting date.

How many Autolus Therapeutics ADSs are covered by Linda Bain’s largest option grant?

The largest reported option grant covers 105,000 American Depositary Shares with an exercise price of 2.3800 per share. Other grants cover 80,000 and 20,000 ADSs at lower and higher exercise prices, giving her a range of potential equity exposure across several future expiration dates.

Are any of Linda Bain’s Autolus Therapeutics options already vested and exercisable?

Yes. A footnote states that one option is “fully vested and exercisable”, meaning all underlying ADSs can be purchased at the stated exercise price. Another option is scheduled to vest in twelve equal monthly installments starting on July 26, 2025, increasing her exercisable position over time.

When do Linda Bain’s Autolus Therapeutics option grants expire?

The disclosed options have staggered expiration dates running from June 21, 2028 through June 26, 2035. Each grant lists a specific expiration date, so the rights to buy the underlying American Depositary Shares must be exercised, if at all, before those respective deadlines.

Does Linda Bain’s Form 3 show any Autolus Therapeutics share purchases or sales?

The data shows no reported buy or sell transactions. All entries are classified as holdings of “Share Option (right to buy)” with zero buy and sell counts in the transaction summary, indicating this filing is an initial statement of existing option positions rather than new market trades.

What vesting schedule is described for one of Linda Bain’s Autolus options?

One option is described as vesting in twelve equal monthly installments beginning on July 26, 2025. This means the right to purchase the underlying American Depositary Shares increases each month over a one-year period, creating a gradual build-up of exercisable options rather than a single cliff vest.
