Item 2.02.Results of Operations and Financial Condition

On January 25, 2023, Lam Research Corporation (the “Company”) issued a press release announcing its financial results for the fiscal quarter ended December 25, 2022, the text of which is attached hereto as Exhibit 99.1. The information in this item of this Current Report on Form 8-K, including Exhibit 99.1, is furnished pursuant to Item 2.02 and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities under that Section. Furthermore, the information in this item of this Current Report on Form 8-K, including Exhibit 99.1, shall not be deemed to be incorporated by reference into the filings of the Company under the Securities Act of 1933, as amended, or the Exchange Act.

Item 2.05.Costs Associated with Exit or Disposal Activities

On January 23, 2023, the Company commenced a workforce reduction that is intended to better align the Company’s cost structure with its outlook for the current economic environment and future business opportunities (the “Restructuring Plan”). The Company expects the Restructuring Plan to entail a workforce reduction of approximately 1,300 employee positions, which is approximately 7% of the Company’s total number of employees. This Restructuring Plan is expected to be substantially completed by the end of the quarter ending June 25, 2023, but the timing of actions may vary by country based on local legal requirements.

The Restructuring Plan is expected to result in total charges of approximately $80.0 million, to be incurred during the quarter ending March 26, 2023. These charges are expected to consist of cash charges related to one-time termination benefits associated with the workforce reduction.

The Company anticipates implementing further cost reduction activities over the next twelve months that are not part of the Restructuring Plan, some of which may result in additional expenditures and charges in future quarters.

Such forward-looking statements relate to, but are not limited to the expected nature, cost, timing, and scope of the Restructuring Plan and future cost reduction activities.

About Lam Research Corporation (LRCX) Earnings

This page provides Lam Research Corporation (LRCX) earnings call transcripts from SEC 8-K filings along with AI-powered predictions for post-earnings price movements. Our machine learning models analyze historical earnings data, pre-earnings price patterns, volume changes, and volatility to predict 1-day, 5-day, and 20-day returns after each earnings release.

Earnings transcripts are sourced directly from SEC EDGAR filings. Predictions are generated using gradient boosting models trained on LRCX's historical earnings reactions. All predicted returns are shown as percentages, and predicted prices are calculated from the closing price at the time of prediction. Past performance does not guarantee future results.
