For the March 2026 quarter, non-GAAP gross margin was $2,913 million, or 49.9% of revenue, non-GAAP operating expenses were $866 million, non-GAAP operating margin was 35.0%, and non-GAAP net income was $1,851 million, or $1.47 per diluted share.

"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.

**Revenue**

The information provided above is only an estimate of what the Company believes is realizable as of the date of this release and does not incorporate the potential impact of any business combinations, asset acquisitions, divestitures, restructuring, balance sheet valuation adjustments, financing arrangements, other investments, or other items that may be completed or realized after the date of this release, except as described below. U.S. GAAP to non-GAAP reconciling items provided include only those items that are known and can be estimated as of the date of this release. Actual results will vary from this model and the variations may be material. Reconciling items included above are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin - amortization related to intangible assets acquired through business combinations, $2.7 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Operating margin - amortization related to intangible assets acquired through business combinations, $3.0 million.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income per diluted share - amortization related to intangible assets acquired though business combinations, $3.0 million; amortization of debt discounts, $0.5 million; and associated tax benefit for non-GAAP items ($0.2 million); totaling $3.3 million.

**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 <u>https://investor.lamresearch.com</u>.
