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.
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."
pecuniary interests financial
"The reporting person disclaims beneficial ownership of the reported securities except to the extent of his pecuniary interests therein."
dispositive power financial
"acts by a majority vote, with the reporting person possessing a veto right, with respect to the voting and dispositive power of the securities"
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.
