[Form 4] Lumentum Holdings Inc. Insider Trading Activity

Rhea-AI Filing Summary

On 11/19/2025, the director acquired 1,283 RSUs, recorded at a price of $0 per share because this is a stock-based compensation grant rather than a market purchase.

The filing states that 100% of the RSUs will vest on the earlier of November 19, 2026 or the day before Lumentum’s next annual meeting of stockholders, as long as the director continues to serve as a service provider under the company’s 2025 Equity Incentive Plan.
