"Lam delivered another strong quarter to cap a record year," said Tim Archer, Lam Research's President and Chief Executive Officer. "Entering 2026, our expanding product and services portfolio is enabling the market's transition to smaller, more complex three-dimensional devices and packages. With AI accelerating, we are ramping execution velocity across the company to support our customers' growth and realize our vision for multi-year outperformance"

**Balance Sheet and Cash Flow Results**

Cash, cash equivalents, and restricted cash balances decreased to $6.2 billion at the end of the December 2025 quarter compared to $6.7 billion at the end of the September 2025 quarter. The decrease was primarily the result of cash deployed for capital return activities and capital expenditures, partially offset by cash generated from operating activities during the quarter.

Deferred revenue at the end of the December 2025 quarter decreased to $2.25 billion compared to $2.77 billion as of the end of the September 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 $226 million as of December 28, 2025 and $131 million as of September 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 as a percentage of revenue - amortization related to intangible assets acquired through business combinations, $2.7 million.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Operating income as a percentage of revenue - 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, $0.7 million; and associated tax benefit for non-GAAP items ($0.2 million); totaling $3.5 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 December 2025 and September 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 September 2025 quarter excludes the impairment of long-lived assets and its associated income tax effect as well as income tax expense from a change in tax law.

Management uses non-GAAP gross margin, operating expense, operating income, operating income as a percentage of revenue, 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>.
