LAM RESEARCH CORP 4

Timothy Archer, President and CEO of Lam Research Corp. (LRCX), exercised 30,000 stock options and sold 30,000 shares of common stock on September 9, 2026 under a Rule 10b5-1 plan.

On September 9, 2026, Timothy Archer, President and CEO of Lam Research Corp., exercised 30,000 employee stock options at an exercise price of approximately $30.03 per share, acquiring 30,000 shares of common stock, and on the same day sold 30,000 shares of common stock at an average price of about $319.26 per share under a Rule 10b5-1 trading plan. The option exercise added 30,000 shares to his direct holdings (reported as 1,105,966 shares after the acquisition), while the subsequent sale reduced his direct holdings to 1,075,966 shares. Archer also reports indirect ownership through a 401(k) plan and his spouse’s 401(k), holding 48,025.72 and 5,670.002 shares of common stock, respectively. The transactions appear to be a classic cashless exercise and sale for liquidity or diversification rather than a net reduction in his overall economic exposure, and his remaining ownership stake remains substantial, including shares subject to unvested restricted stock units.
