Lam Research (LRCX) has experienced significant stock price volatility in the past, with drops exceeding 30% within a two-month period on multiple occasions. The company now faces several potential risks in 2026, including margin compression due to an unfavorable product mix, escalating China revenue concentration risk, and concerns about excess inventory and channel stuffing. These factors could lead to a reality check for the stock's recent record highs.

Why it matters

Lam Research is a key player in the semiconductor equipment industry, and its performance is closely watched by investors. Any significant declines in the company's stock price or financial performance could have broader implications for the semiconductor sector and the overall technology market.

The details

Lam Research is expected to face the following key risks in 2026: 1) Margin compression due to an unfavorable product mix, with the company's gross margin projected to decline sequentially to 48.5% +/- 1% in the December 2025 quarter. This could lead to multiple compression if peak margins are seen as a thing of the past. 2) Escalating China revenue concentration risk, with the company's revenue from China expected to account for less than 30% of total revenues in 2026, down from a higher level previously. This could result in a de-rating of the company's valuation multiple due to unpredictable geopolitical risk and earnings fluctuations. 3) Excess inventory and the risk of channel stuffing, which could lead to future revenue and earnings losses if current sales are drawing from future demand, and potentially significant stock price drops if inventory write-downs or a notable slowdown in new orders occurs.

  • Lam Research is expected to report its Q2 2026 earnings on January 28, 2026, when the margin compression risk is likely to become evident.
  • The China revenue concentration risk is expected to materialize over the next 2-4 quarters.
  • The excess inventory and channel stuffing risk is expected to become apparent in Q3-Q4 2026.
