“Lam delivered record revenue, operating margin and earnings per share in the June quarter as AI-driven demand continues to reshape the semiconductor industry,” said Tim Archer, Lam Research's President and Chief Executive Officer. “Our strategic investments and technology leadership are helping customers accelerate through rising manufacturing complexity, positioning Lam for a third consecutive year of outperformance in 2026.”







Balance Sheet and Cash Flow Results
Cash, cash equivalents, and restricted cash balances increased to $5.60 billion at the end of the June 2026 quarter compared to $4.77 billion at the end of the March 2026 quarter. The increase was primarily driven by cash generated from operating activities, partially offset by cash deployed for capital return activities during the quarter.
Deferred revenue at the end of the June 2026 quarter increased to $2.43 billion compared to $2.22 billion as of the end of the March 2026 quarter. Lam's deferred revenue balance does not include shipments to customers in Japan, to whom title 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 $490.2 million as of June 28, 2026 and $434.3 million as of March 29, 2026.

Use of Non-GAAP Financial Results
In addition to U.S. GAAP results, this press release also contains non-GAAP financial results.

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.
