"filed a Form 144 reporting proposed sales of Class A Common stock"

10b5-1 regulatory

"10b5-1 Sales for AGARWAL 2018 FAMILY TRUST 620 8th Avenue"

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.
