Context

• The Class B Units of Viant Technology LLC are exchangeable one-for-one into the issuer’s Class A common stock; the filing shows conversion/exercise at no cash cost and subsequent sales, effectively converting and liquidating those units. The sales were executed under a pre-established 10b5-1 plan by Capital V LLC, indicating pre-arranged sales rather than ad-hoc insider selling. As always, sales pursuant to 10b5-1 plans and conversions are routine corporate/owner liquidity actions and should not be interpreted alone as a signal of management sentiment.
