Lam Research Elevates Sesha Varadarajan to COO to Accelerate Product and Service Delivery

Lam Research tightens operational leadership to accelerate product and service delivery

MAIN TOPIC — Strategic COO appointment to speed innovation and market response

Lam Research is elevating Sesha Varadarajan to chief operating officer, a move designed to accelerate the company’s product development and customer-facing services as semiconductor demand rises. Effective March 6, 2026, Varadarajan keeps oversight of the global product portfolio while adding responsibility for the customer support business group, corporate strategy and government affairs, aligning product and service development to shorten development cycles and respond faster to technology inflections.

In his prior role as head of the global product group, Varadarajan drives rapid product innovation targeting increased deposition and etch intensity across new process nodes, positioning Lam to capitalize on heightened equipment content per wafer. As COO he is charged with expanding Lam’s served available market, growing market share and accelerating services revenue, with explicit emphasis on reducing cycle times and improving delivery metrics across customer sites worldwide.

The promotion concentrates decision-making that links engineering, service and customer engagement, which Lam frames as central to converting technology inflections into commercial opportunities. The company positions the change as a way to accelerate operational velocity — enabling quicker product introductions, tighter service integration and faster responsiveness to customer roadmaps without altering Lam’s existing manufacturing footprint strategy.

Lam also expands Karthik Rammohan’s responsibilities to senior vice president, global operations and enterprise solutions, keeping his leadership of global manufacturing and supply chain while adding oversight of enterprise systems including IT, quality and facilities. Rammohan brings experience building a diverse manufacturing footprint and supply-chain capabilities, and the expanded role is intended to strengthen operational resilience and support higher service penetration.

The appointments coincide with the planned retirement of Pat Lord, who steps down after more than two decades at Lam and Novellus. Lam says the leadership changes support capital investment priorities and operational scalability, positioning the company to capture growth as semiconductor demand accelerates and to improve delivery and service metrics across its worldwide operations.
