A key highlight was the achievement of a record quarter for foundry revenues in March 2025, reflecting strengthened investments in this market segment and Lam's solid product momentum in leading-edge inflections. This contributed to Systems revenue of $3.04 billion for the quarter and $8.05 billion for the nine months, up from $2.40 billion and $6.75 billion respectively in the prior year.
Profitability metrics also demonstrated robust performance. The gross margin percentage in the March 2025 quarter reached a record level for the company since the Lam/Novellus merger, coming in at 49.0%. This improvement was primarily driven by favorable customer and product mix, as well as enhanced efficiencies stemming from Lam's "close-to-customer" manufacturing strategy, which leverages its global footprint including the rapidly ramped Malaysia factory. For the nine months ended March 30, 2025, the gross margin was 48.2%, up from 47.2% in the prior year period, reflecting improved factory efficiencies partially offset by mix and transformation costs.
Operating expenses increased sequentially to $751.9 million in March 2025, primarily due to continued investment in R&D ($525.9 million) focused on roadmap differentiation, as well as higher employee-related costs and lab spending. Despite this investment, the operating margin expanded to 32.8% in the March 2025 quarter, near the high end of guidance and above the 30.7% in the prior quarter, driven by higher revenue and stronger gross margins. For the nine months, operating income was $4.16 billion, up from $3.14 billion, resulting in an operating margin of 31.4%.
The Customer Support Business Group (CSBG) also contributed meaningfully, generating $1.68 billion in revenue in the March 2025 quarter and $5.21 billion for the nine months, a 21% increase year-over-year for the quarter. While sequentially down slightly from December 2024 due to lower Reliant systems revenue, this was partly offset by record upgrade revenue, demonstrating the value customers place on maximizing installed equipment performance through Lam's offerings.
From a liquidity perspective, Lam maintains a strong balance sheet. As of March 30, 2025, cash and cash equivalents totaled $5.45 billion. While this was a slight decrease from $5.85 billion at June 30, 2024, it reflects significant capital return activities and debt repayment.
For the nine months ended March 30, 2025, net cash provided by operating activities was a robust $3.62 billion.
