On this Form 4, Esam Elashmawi, SVP, Strategy and Marketing of Lattice Semiconductor Corp (LSCC), reported routine tax-withholding transactions and a series of planned open-market sales of common stock. On 2026-08-16 and 2026-08-17, the issuer withheld 593 and 438 shares, respectively, at approximately $130.46 and $132.67 per share to satisfy tax obligations upon the vesting of restricted stock units, leaving Elashmawi with 171,600 and then 171,162 shares. On 2026-08-17, under a pre-arranged Rule 10b5-1 trading plan adopted on 2026-05-18, he sold multiple blocks of common stock: 1,934 shares at $132.7906, 1,898 shares at $133.7708, 8,882 shares at $134.9523, 1,828 shares at $135.8299, and 1,200 shares at $136.5928, for total sale proceeds of roughly $2.1 million. After these sales, he directly owned 155,420 shares. Using the reported sale prices as a proxy (mid-$130s per share), his remaining stake is worth on the order of $21 million, indicating that while the sales are sizable, they represent only a portion of his overall equity position and appear to be part of a structured diversification and tax-management program.
