Lam Research’s Q1 Earnings Snapshot

Fremont, California-based Lam Research’s revenue for the first quarter of the fiscal year 2026 grew 27.6% year-over-year (YoY), although slowing from the 33.6% pace seen in the previous quarter, while adjusted earnings per share (EPS) jumped nearly 47%. The revenue marked a quarterly record.

-Revenue: $5.32 billion Vs. Fiscal.ai-compiled consensus of $5.23 billion

-Adjusted EPS: $1.26 Vs. $1.22 consensus

-Adjusted gross margin: 35%, up 60 basis points from Q4’25

Lam Research’s CEO Tim Archer said the company’s innovations are helping its customers address major artificial intelligence (AI)-driven manufacturing inflections. “We are executing well in an environment of tremendous opportunity, and with our expanding portfolio of products and solutions across critical device segments, we are strongly positioned for continued growth.”

Among business segments, systems revenue, accounting for roughly 67% of the total revenue, jumped about 49% and 3% sequentially. Geographically, China accounted for 43% of the total revenue, Taiwan 19%, Korea 15% and Japan 10%.

Lam Research’s Outlook

The company guided second-quarter revenue in the range of $4.9 billion to $5.5 billion and adjusted EPS of $1.05 to $1.25. Analysts, on average, expect the metrics to be at $5.23 billion and $1.03, respectively. It expects adjusted margins to come in at 33% +/- 1%.

On the earnings call, CEO Archer said the quarterly revenue guidance incorporated roughly a $200 million revenue impact from the recently announced 50% affiliate rule restricting shipments to certain domestic Chinese customers, according to a transcript provided by Koyfin. The company expects the rule to impact its full-year revenue by about $600 million. 

Archer expects the China region to represent less than 30% of our overall revenues in calendar year 2026. Worldwide wafer fabrication equipment (WFE) spending has been shaping up to be slightly better than the company’s prior view of $105 billion in the calendar year 2025, predominantly due to better-than-expected high-bandwidth memory (HBM)-related investments, he added.

What Retail’s Feeling About LRCX Stock

A bullish user lamented that “good companies” are being held down as usual, adding that the stock could climb to $300 next year. LRCX stock settled in Wednesday’s regular session at $141.25.

Another user suggested that the post-earnings stock reaction may have been due to the soft guidance, which potentially triggered profit-taking. ‘Planning to reload later,” they said.

According to Koyfin, the consensus price target for LRCX stock is $130.96, implying over 7% downside from current levels.
