derivative security financial

"transaction_code_description: "Exercise or conversion of derivative security""

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.

What insider transaction did BEAM president Giuseppe Ciaramella report?

Giuseppe Ciaramella reported exercising stock options to acquire 35,505 Beam Therapeutics common shares. The Form 4 shows option exercises, not open‑market trades, reflecting the use of previously granted equity awards as part of long-term compensation.

How many Beam Therapeutics (BEAM) shares were acquired in this Form 4?

The filing shows option exercises for 35,505 Beam Therapeutics common shares. These came from two stock option grants, delivering 29,000 shares at one strike price and 6,505 shares at another, all recorded as derivative exercises rather than market purchases.

At what prices did the BEAM options exercised by the president vest?

Were any Beam Therapeutics (BEAM) shares sold in this insider filing?

No sales are reported; all transactions are coded “M” for derivative exercises or conversions. This indicates the president converted stock options into common shares, with no open‑market dispositions or tax-withholding share transactions shown in the reported data.

What does the vesting schedule in BEAM’s Form 4 footnote indicate?

The footnote explains that 25% of the option shares vested one year after the February 26, 2018 commencement date, with the remaining 75% vesting in 36 equal monthly installments. This describes a standard multi-year vesting structure for Beam’s equity compensation.

Do any stock options remain after the BEAM president’s exercises?

The derivative summary section is empty, indicating no remaining derivative positions are listed in this filing. That suggests the options covered here were fully exercised, although any other awards not referenced would appear in separate disclosures.
