"10b5-1 Sales for DOMINIC PHILLIPS 1 DE HARO STREET"

A 10b5-1 plan is a pre-set schedule that lets company insiders buy or sell shares according to written instructions made when they do not possess material, nonpublic information. Think of it as a timed automatic payment for stock trades: it helps insiders avoid accusations of trading on secret information and gives outside investors a clearer signal about whether sales are routine or potentially informative about the company’s prospects.

Restricted Stock Units financial

They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
