FAQ

What insider transaction did Beta Bionics (BBNX) report for its CFO?

Beta Bionics reported that CFO Stephen Feider received a grant of 110,342 employee stock options. These options relate to the company’s common stock and represent a compensation award, not an open-market purchase or sale of existing shares by the executive.

What is the exercise price of the new Beta Bionics (BBNX) CFO stock options?

The newly granted stock options to the Beta Bionics CFO have an exercise price of $12.63 per share. This means he can later buy common shares at $12.63, regardless of the market price, once the options are vested and exercisable.

How many Beta Bionics (BBNX) shares are covered by the CFO’s option grant?

The CFO’s option grant covers 110,342 shares of Beta Bionics common stock. These are derivative securities, giving the right to purchase that number of shares at the fixed exercise price once vesting and other conditions are satisfied over time.

When do the Beta Bionics (BBNX) CFO stock options vest?

The stock options granted to the Beta Bionics CFO vest in 36 equal monthly installments beginning March 1, 2026. This creates a three-year vesting schedule, so he gains the right to exercise an additional portion of the options each month during that period.

When do the newly granted Beta Bionics (BBNX) CFO options expire?

The newly granted stock options to the Beta Bionics CFO expire on February 26, 2036. If they are not exercised by that expiration date, any unexercised options will lapse and no longer provide the right to purchase Beta Bionics common stock.

Did the Beta Bionics (BBNX) CFO buy or sell shares in the market in this filing?

No market buy or sell occurred. The Form 4/A shows a compensation-related grant of employee stock options to the CFO, coded as an acquisition (A). It reflects an award of derivative securities, not an open-market transaction in existing Beta Bionics shares.
