FREMONT, Calif. — Lam Research Corp. today announced it is elevating the roles of two proven leaders as the company enters its next phase of growth. Effective March 6, 2026, Sesha Varadarajan will transition to the role of Chief Operating Officer (COO). The company further announced that Karthik Rammohan will assume an expanded role as Senior Vice President (SVP), Global Operations and Enterprise Solutions. Both will play an integral role in Lam’s objectives to deliver even greater value to customers and drive Lam’s future outperformance by bringing the operational velocity essential for an accelerating semiconductor demand environment.
Varadarajan will maintain oversight of Lam’s global product portfolio, and add Lam’s customer support business group, corporate strategy, and government affairs capabilities to his remit. This new role aligns Lam’s global product and service development to innovate faster and deliver on strategic objectives. In his previous role as head of Lam’s global product group, he has driven rapid product innovation to successfully capitalize on increasing deposition and etch intensity in recent technology inflections. As COO, he will build upon that experience to advance Lam’s plans to further expand its served available market, increase its market share, and accelerate growth in its services business.
Varadarajan succeeds Pat Lord, who will retire following a remarkable career of more than two decades with Lam and Novellus. Lord was instrumental in shaping the company’s operational foundation and strengthening customer partnerships to support the extraordinary expansion of the semiconductor industry.
Rammohan will maintain leadership of the company’s global manufacturing and supply chain and assume oversight of critical enterprise solutions including information technology systems, quality and facilities. He brings deep expertise and a proven track record of results, having led the expansion of a diversified manufacturing network and a more flexible, resilient global supply chain. In his new role, Rammohan will bring the same rigor and execution excellence to accelerate the scaling of Lam’s operational footprint and transformation during this next phase of rising demand.
“Pat’s leadership has helped build the Lam we know today. We thank him for his many contributions and wish him well in his retirement,” said Tim Archer, president and CEO of Lam Research. “With Sesha’s and Karthik’s newly expanded roles, we are increasing velocity across our operations from product innovation and manufacturing to installation and maintenance to drive Lam’s outperformance in the AI era.”
