Nasdaq surges 1% as tech lifted by SpaceX, Tesla on Musk’s hint at possible merger
Investing.com -- Lam Research Corp (NASDAQ:LRCX) shares slipped 6% in after-hours trading Wednesday despite delivering fiscal first-quarter results and forward guidance that topped Wall Street expectations.
For the quarter ended September 27, 2026, the semiconductor equipment manufacturer posted non-GAAP earnings of $2.20 per share on revenue of $8.22 billion. The results edged out analyst estimates of $2.18 per share and revenue of $8.13 billion, reflecting a 22% sequential surge in top-line growth.
Operational efficiency remained a highlight as non-GAAP gross margin expanded 40 basis points quarter-over-quarter to 52.4%, while non-GAAP operating margin climbed to 40.2%. Chief Executive Officer Tim Archer noted that elevated demand driven by artificial intelligence and increased chip complexity allowed the company to generate record quarterly revenue and profitability.
Looking ahead to the quarter ending December 27, 2026, Lam Research projects revenue of $8.60 billion, give or take $400 million, surpassing the consensus forecast of $8.538 billion. The company anticipates non-GAAP diluted earnings per share of $2.33, plus or minus $0.15, slightly higher than analyst projections centered at $2.32 per share.
Geographically, China represented the primary driver of revenue during the period, accounting for 35% of total sales, followed by Korea at 20% and Taiwan at 18%. Systems revenue expanded sharply to $5.73 billion from $4.25 billion in the prior quarter, highlighting sustained demand for leading-edge deposition and etch equipment.
Against that backdrop, the company strengthened its liquidity position, ending the quarter with $7.45 billion in cash, cash equivalents, and restricted cash. Operating cash flow reached $3.50 billion, enabling management to return over $1.3 billion to shareholders through dividend payments and treasury stock repurchases.
Beyond the relatively in-line earnings outlook, several secondary factors compounded the pressure on the stock during extended trading. First, the wide guidance range for second-quarter revenue ($8.2 billion to $9.0 billion) and EPS ($2.18 to $2.48) introduced potential downside risks that concerned investors expecting a tighter, more confident outlook. Additionally, after a nearly 80% rise in the stock over the past year heading into the report, market participants took advantage of the report to take profits amid broader pre-earnings caution across the chip-equipment sector.
Ultimately, the market reaction underscores a classic "sell-the-news" dynamic where solid execution was already priced into the stock's valuation. While short-term volatility reflects heightened expectations surrounding forward guidance, Lam's expanding margins and robust balance sheet suggest its core operational trajectory remains intact as AI infrastructure investments accelerate.
