Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

Form S-8 regulatory

"Securities to be sold, acquired through RSU/PSU or upon option exercise, were registered on Form S-8."

A Form S-8 is a U.S. Securities and Exchange Commission registration that lets a public company set aside shares for employee benefit plans and stock-based compensation. Think of it as opening a dedicated account that authorizes the company to issue or reserve stock for workers and directors; it matters to investors because it enables share dilution when those awards are granted or exercised and signals how management is compensated and incentivized.

10b5-1 regulatory

"10b5-1 Sales for ALEXIS T LEQUOC 620 8th Avenue, 45th Floor New York NY 10018"

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.

RSU/PSU financial

"Securities to be sold, acquired through RSU/PSU or upon option exercise, were registered on Form S-8."
