LLC Units financial
"Represents common units of Brilliant Earth, LLC (the "LLC Units") and shares of Class B"
LLC units are ownership stakes in a limited liability company, similar to shares in a corporation; each unit represents a portion of the company’s profits, losses and often voting power. For investors, LLC units matter because they determine how much money and control someone gets, how easily an interest can be sold, and how income is taxed and reported — think of owning slices of a pie that also decide how the pie is cut and shared.
Class B common stock financial
"Consists of (i) 31,098,704 shares of Class B common stock (and associated LLC Units)"
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
weighted average sale price financial
"This transaction was executed in multiple trades at prices ranging from $1.25 to $1.40, inclusive. The reported price reflects the weighted average sale price."
beneficial ownership financial
"The reporting persons disclaim beneficial ownership of the reported securities except to the extent"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
dispositive power financial
"a three member investment committee of GP III acts by a majority vote, with Gavin Turner possessing a veto right, with respect to the voting and dispositive power"
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
