Class B Units financial
"The Class B Units of Viant Technology LLC ("Class B Units") are exchangeable..."
weighted average price financial
"The price reported in Column 4 is a weighted average price, based on the Reporting Person's pro rata portion..."
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.
indirect pecuniary interest financial
"may therefore be deemed to have an indirect pecuniary interest in one-third of Capital V LLC's total holdings."
10b5-1 plan regulatory
"Shares sold pursuant to a 10b5-1 plan adopted by Capital V LLC on March 18, 2025..."
A 10b5-1 plan is a pre-arranged strategy that allows company insiders to buy or sell their shares at predetermined times and prices, even while they are aware of confidential information. It acts like a scheduled appointment for trading, helping ensure transactions happen transparently and legally, which can reassure investors that trades are not based on insider knowledge.
