Context
This is an exercise-and-sell (same-day) transaction: Harish exercised vested options and sold the resulting shares the same day under a 10b5-1 plan, a common approach for liquidity or tax management. The filing is factual and pre-planned under an established trading plan; it should not be read as a statement of his view on the company’s prospects.
