weighted average price financial
"The price reported in Column 4 is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
indirectly beneficially own financial
"Mr. Meister may be deemed to indirectly beneficially own these shares"
pecuniary interest financial
"disclaims beneficial ownership of the reported securities except to the extent of his or its pecuniary interest"
restricted stock units financial
"shares of Class A Common Stock that were issued upon the vesting of restricted stock units"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Section 16 of the Securities Exchange Act of 1934 regulatory
"for purposes of Section 16 of the Securities Exchange Act of 1934, as amended"
A provision of federal securities law that requires company insiders—directors, officers and large shareholders—to publicly report their stock holdings and trades and to surrender any “short-swing” profits from purchases and sales within a six-month window. It acts like a rule that forces leaders to announce their trades and prevents quick buy-sell windfalls, giving investors transparency into insider activity and reducing opportunities for unfair gain.
