"Lam delivered record revenue and EPS in the March quarter as AI-driven demand reshapes the semiconductor industry," said Tim Archer, Lam Research's President and Chief Executive Officer. "Our strategic investments and the velocity of our execution are generating strong momentum, enabling customers' AI roadmaps and driving Lam's outperformance during this critical phase of industry growth."
Balance Sheet and Cash Flow Results
Cash, cash equivalents, and restricted cash balances decreased to $4.77 billion at the end of the March 2026 quarter compared to $6.20 billion at the end of the December 2025 quarter. The decrease was primarily the result of cash deployed for capital return activities, principal payment on debt instruments, and capital expenditures, partially offset by cash generated from operating activities during the quarter.
Deferred revenue at the end of the March 2026 quarter decreased slightly to $2.22 billion compared to $2.25 billion as of the end of the December 2025 quarter. Lam's deferred revenue balance does not include shipments to customers in Japan, to whom control does not transfer until customer acceptance. Shipments to customers in Japan are classified as inventory at cost until the time of acceptance. The estimated future revenue from shipments to customers in Japan was approximately $434 million as of March 29, 2026 and $226 million as of December 28, 2025.

Use of Non-GAAP Financial Results
In addition to U.S. GAAP results, this press release also contains non-GAAP financial results. The Company's non-GAAP results for both the March 2026 and December 2025 quarters exclude amortization related to intangible assets acquired through business combinations, the effects of elective deferred compensation-related assets and liabilities, amortization of note discounts, and the net income tax effect of non-GAAP items. In addition, the March 2026 quarter excludes expenses associated with workforce optimization activities and their associated income tax effect.
Management uses non-GAAP gross margin, operating expense, operating income, operating margin, net income, and net income per diluted share to evaluate the Company's operating and financial results. The Company believes the presentation of non-GAAP results is useful to investors for analyzing business trends and comparing performance to prior periods, along with enhancing investors' ability to view the Company's results from management's perspective. Tables presenting reconciliations of non-GAAP results to U.S. GAAP results are included at the end of this press release and on the Company's website at https://investor.lamresearch.com.
