Insights

Insider Trading Analyst

CEO Jitendra Mohan sold 52,743 shares (~$5.3M) via planned 10b5-1 sales while maintaining substantial 9.9M share position across multiple trusts.

This Form 4 filing reveals that Astera Labs CEO and Director Jitendra Mohan sold 52,743 shares on June 20, 2025, at an average price of $100.86 per share, generating approximately $5.3 million. The transactions were executed under a pre-established Rule 10b5-1 trading plan adopted on December 2, 2024, which allows insiders to sell shares at predetermined times regardless of potential material non-public information they may possess.

Despite this sale, Mohan retains significant ownership in Astera Labs with approximately 9.92 million shares across multiple ownership structures: 2.26 million shares held directly and 7.65 million shares held indirectly through various trusts. The largest position is 4.34 million shares in a Living Trust, with additional holdings distributed across five other trust entities ranging from 512,218 to 762,217 shares each.

The structured nature of these sales across six different trust entities in nearly identical amounts (approximately 8,790 shares each) suggests careful estate planning rather than an urgent liquidation. This systematic selling represents only about 0.5% of Mohan's total holdings, indicating this is likely part of a routine diversification strategy rather than a significant reduction in his position. The CEO's continued substantial ownership aligns his interests with long-term shareholders despite this modest reduction.
