Key numbers
| Metric | Latest | Change | Source |
|---|---|---|---|
| Shares sold | 51,915 shares | SEC Form 4 | |
| Sale price range | $44.83 to $46.32 per share | SEC Form 4 | |
| Total sale value | about $2.38 million | SEC Form 4 | |
| Shares held after sale | 377,211 shares | SEC Form 4 | |
| Shares sold as share of pre-trade holding | 12.1% | Calculated from SEC Form 4 |
Why it matters
The 51,915 shares were about 12.1% of the holding before the trade, which shows the sale trimmed a meaningful slice of his stake. Padisetty still held 377,211 shares after the sale, and the filing says that total includes shares that have not yet vested.
The reported value was about $2.38 million, so this was a partial reduction rather than a full exit. Because the stock was sold in multiple transactions, the filing gives weighted averages and price ranges instead of one execution price. The strongest caveat is the Rule 10b5-1 plan, because the filing says the trades were made under a plan entered into on June 29, 2026.
For experienced investors, the report is best read as a documented insider trim and ownership update. The 51,915 shares were about 12.1% of the pre-trade holding, which is the cleanest comparison in the filing. It quantifies the trim and leaves the explanation to the plan disclosure.
What's next
Later Form 4 filings will be the cleanest follow-up on whether Padisetty keeps trimming his stake or leaves it near 377,211 shares. Further sales would strengthen the selling signal, while a stable stake would weaken it. This filing sets the post-sale ownership baseline at 377,211 shares.
