Lam Research elevates Varadarajan to COO to speed product-to-service delivery

Operational overhaul at Lam Research aims to speed product-to-service delivery

Lam Research elevates Sesha Varadarajan to chief operating officer and expands Karthik Rammohan’s remit as it retools operations to meet surging semiconductor demand. The changes take effect on March 6, 2026 and are designed to shorten cycle times and accelerate innovation across deposition and etch technologies that are driving recent industry inflections. Company leadership frames the moves as critical to increasing operational velocity and aligning product development more closely with customer support and services.

Varadarajan keeps oversight of Lam’s global product portfolio and adds responsibility for the customer support business group, corporate strategy and government affairs, a consolidation intended to align product and service development. In his prior role leading the global product group, he drives rapid product innovation to capitalize on rising process intensity, and as COO he is charged with expanding Lam’s served available market, growing market share and accelerating services revenue. The reorganization places commercial, product and policy levers under a single operator to reduce handoffs and speed time-to-customer for new tool and service offerings.

Rammohan continues to lead global manufacturing and supply chain and assumes oversight of enterprise solutions including information technology systems, quality and facilities, broadening his accountability for operational execution. He is credited with expanding Lam’s diverse manufacturing footprint and strengthening supply-chain capabilities, work the company says is essential as it scales capacity to meet cyclical and structural demand. Lam positions both executives as integral to delivering more value to customers through improved delivery metrics and greater service penetration.

Succession underscores continuity in operations

The appointments formalize the succession of Varadarajan into a role previously held by Pat Lord, who will retire after more than two decades at Lam and Novellus. Company commentary emphasizes Lord’s role in shaping the operational foundation that supports the semiconductor industry’s rapid expansion.

Change aims to strengthen scalability and responsiveness

Lam says the leadership moves support capital investment priorities and operational scalability across worldwide sites, enabling faster response to market inflections while targeting continued profitable growth. The company highlights expected benefits such as shorter cycle times, improved delivery performance and increased services revenue as it navigates accelerating semiconductor demand.
