Harris Isaac Hosojiro received vested RSU awards in Lumentum Holdings Inc. common stock on three dates in 2026 with shares withheld to cover taxes, resulting in modest net increases to his direct holdings.

On this Form 4, reporting person Harris Isaac Hosojiro, formerly serving as Interim Chief Procurement Officer of Lumentum Holdings Inc., reported three routine monthly vestings of fully vested restricted stock units (RSUs) on March 31, April 30, and May 29, 2026, each delivering common shares at no cost, along with corresponding share withholdings to cover income tax obligations. On March 31, 374 RSUs vested and were added to his direct holdings, while 125 shares were simultaneously withheld at an implied price of about $5.62 per share (total tax value approximately $703), leaving him with 12,649 shares. On April 30, 320 RSUs vested and 145 shares were withheld at an implied price of about $6.22 per share (tax value roughly $902), resulting in post‑transaction ownership of 12,824 shares.
