Employment Terms
| Item | Detail |
|---|---|
| Role start date | Senior Vice President, Product Development since June 2021 |
| Change-in-control agreement | Exists (Exhibit 10.18 referenced in filings); specific severance multiples not disclosed for Sankar |

Investment Implications
- Ownership alignment appears positive: insider open-market share purchases in 2022 and new option grant in 2025 support continued alignment and retention via multi-year vesting; hedging/pledging bans reduce misalignment risk .
- Equity acceleration under CIC protects the executive but can create incremental transaction dilution; severance cash multiples for Sankar are not disclosed, limiting precise modeling of potential change-of-control costs .
- Pay-for-performance environment: no 2024 bonuses paid to named executive officers under the Incentive Plan due to under-threshold attainment, signaling tighter cash incentive alignment; Sankar’s specific payouts are not disclosed, so trading signals should rely on Form 4 activity and vesting schedules rather than cash bonus outcomes .
