The filing discloses proposed resale activity under 10b5-1 plans by an affiliated person, listing multiple sale dates, share counts and dollar amounts between 12/01/2025 and 01/30/2026. It is a notice of planned sales, not proof of completed trades.

Are the 10b5-1 sales in the Form 144 already executed?

Will Dropbox (DBX) receive proceeds from these Form 144 sales?
