Insights

Insider Transactions Expert

Small planned sale and recent disposals show routine insider liquidity.

The filing details a proposed sale of 837 Class A shares valued at $15,066, which is de minimis against the 324,760,095 shares outstanding, indicating limited direct impact on the public float.

Recent reported sales by associated Insight Partners entities total 672 shares for $12,299.94 across 07/07/2025 to 10/03/2025, consistent with phased liquidity rather than a single large disposition; monitor any increase in sale cadence over the next quarter.

Capital Markets Analyst

Transaction size is immaterial to market supply but shows active secondary trading.

At an aggregate market value of $15,066 for 837 shares, the planned sale represents a negligible fraction of the outstanding share count and is unlikely to move market pricing on its own.

Because the broker is Raymond James & Associates and prior trades occurred recently, short-term trading volume impacts should be modest; investors may note timing around 10/06/2025 if combined with other secondary offers.
