What insider transaction did GENB's CTO report on this Form 4?

Generate Biomedicines’ CTO, Gevorg Grigoryan, reported receiving two stock option grants. One covers 295,608 shares and another 196,368 shares, both at a $0.00 exercise price, reflecting equity-based compensation rather than open-market buying or selling activity.

How many stock option shares were granted to the GENB CTO?

The CTO received options over 295,608 shares in one grant and 196,368 shares in another. Each grant is recorded as a direct award, giving him rights to buy Generate Biomedicines shares under the specified vesting schedules and conditions.

What are the vesting terms for the 295,608-share option grant at GENB?

The 295,608-share option grant vests in two equal installments on February 19, 2029 and February 19, 2030. Vesting on each date is subject to Gevorg Grigoryan’s continued service with Generate Biomedicines through the applicable vesting date.

How does the 196,368-share stock option grant at GENB vest?

The 196,368-share stock option grant vests in forty-eight equal monthly installments following February 19, 2026. Each monthly vesting tranche requires the CTO to continue serving at Generate Biomedicines on the applicable vesting date to receive that portion.

Were the GENB CTO’s stock options acquired through market purchases?

No. Both stock option positions were acquired as grants with a $0.00 exercise price per share. They are compensatory awards, not open-market purchases, and become exercisable only as the stated vesting conditions tied to continued service are satisfied.

Does this GENB Form 4 indicate any insider share sales?

The filing shows no reported sales by the CTO. It reflects two derivative transactions coded as awards or other acquisitions (Code A), representing newly granted stock options rather than dispositions of existing Generate Biomedicines common stock holdings.
