Lam Research Corp. reported fiscal Q4 2025 revenue of $5.34 billion, up 22.1 % year‑over‑year and beating the consensus estimate of $5.25 billion by 1.8 %. Non‑GAAP diluted earnings per share were $1.27, surpassing the $1.17 estimate by $0.10 or 8.7 %. The company’s record‑year performance was driven by robust demand for advanced packaging and high‑bandwidth memory, which helped offset headwinds in legacy product lines.
Systems revenue rose to $3.36 billion, a 28 % increase from the same period a year ago, reflecting strong uptake of AI‑accelerated chip manufacturing equipment. Customer support revenue climbed to $1.99 billion, up 13.5 % YoY, as customers continued to invest in spares and upgrades. The mix shift toward higher‑margin systems contributed to the overall revenue growth, while the support segment’s growth underscored the company’s recurring revenue base.
Non‑GAAP gross margin fell to 49.7 %, a 90‑basis‑point decline from 50.6 % in the prior quarter, largely due to a shift toward lower‑margin legacy products and modest cost inflation. Operating income was 34.3 % of revenue, down 70 bps from 35.0 % in the previous quarter, but the company maintained strong profitability through disciplined cost management and pricing power in its core etch and deposition markets.
For fiscal Q1 2026, Lam guided revenue of $5.70 billion, +/- $300 million, and non‑GAAP EPS of $1.35, a 6.2 % increase from the current quarter. The guidance reflects management’s confidence in sustained AI‑driven demand and the company’s ability to maintain pricing power. CEO Timothy Archer said, “Lam delivered another strong quarter to cap a record year… With AI accelerating, we are ramping execution velocity across the company to support our customers’ growth.” CFO Douglas Bettinger added, “In calendar year 2025, revenue was a record coming in at $20.6 billion, up 27 % year‑over‑year.”
Lam’s full‑year 2025 results were record‑setting, with revenue of $20.6 billion and a non‑GAAP gross margin of 49.9 %, the highest since the Novellus merger in 2012. Analysts noted the strong earnings beat and guidance, highlighting the company’s positioning in the AI and advanced packaging markets. The market reaction was positive, with investors acknowledging the company’s execution and forward‑looking outlook.
Headwinds remain in the form of geopolitical tensions affecting China exposure and modest cost inflation, which could pressure margins in the near term. However, the company’s focus on AI, gate‑all‑around transistors, and advanced packaging provides a tailwind that is expected to drive continued growth. Lam’s ability to balance cost discipline with strategic investments positions it well to capitalize on the expanding semiconductor equipment market.
