Lam Research Corp. announced that Sesha Varadarajan will become Chief Operating Officer effective March 6, 2026, and that Karthik Rammohan will take on an expanded role as Senior Vice President, Global Operations and Enterprise Solutions. The change follows the retirement of long‑time COO Patrick J. Lord, who has served the company for more than two decades.
Varadarajan will keep oversight of Lam’s global product portfolio while adding responsibility for the Customer Support Business Group, corporate strategy, and government affairs. CEO Tim Archer said the move “increases velocity across our operations from product innovation and manufacturing to installation and maintenance to drive Lam’s outperformance in the AI era.” The expanded remit is intended to align product development, service delivery, and strategic initiatives so that the company can capture the accelerating demand for AI‑enabled chips.
Rammohan will continue to lead global manufacturing and supply‑chain operations and will oversee enterprise solutions, including information technology systems, quality, and facilities. Archer noted that the broadened role “will enable us to accelerate execution speed across the company to support our customers’ growth.” The expansion reflects Lam’s focus on high‑margin AI and advanced packaging segments, where operational efficiency and rapid deployment are critical.
In the same announcement, Lam added Anirudh Devgan to its board of directors. The leadership reshuffle comes as the semiconductor industry experiences a tailwind from AI adoption, with demand for advanced packaging and wafer‑level processes rising sharply. The company’s market share in etch and deposition remains strong, positioning it to benefit from the AI boom.
The combined leadership changes signal Lam’s intent to boost operational velocity and align its product and service capabilities with the AI‑driven market. By placing experienced executives in key roles, the company aims to accelerate execution, strengthen customer support, and maintain its competitive edge in a rapidly evolving industry.
