Lam Research Corporation (ISIN US5128073062) closed at USD 310.99 on Nasdaq on September 22, 2026, up 2.88 percent from the prior close. The move followed a reported fiscal fourth-quarter revenue increase of 30 percent to USD 6.72 billion and a forecast of approximately USD 8.1 billion for the next quarter.

Revenue reaches USD 6.72 billion

According to MarketBeat on September 22, 2026, Lam Research generated USD 6.72 billion in fiscal fourth-quarter revenue, up 30 percent year over year. Quarterly earnings per share reached USD 1.82, compared with a consensus estimate of USD 1.69 and USD 1.33 in the year-earlier quarter.

The comparison points to both earnings growth and a measurable beat against expectations. The same report said the company guided for approximately USD 8.1 billion in September-quarter revenue, more than 20 percent above the preceding quarter, while targeting operating margins in the mid-40 percent range.

Margin expansion meets valuation risk

Fiscal fourth-quarter non-GAAP operating margin was 38.4 percent, compared with 35 percent in the previous quarter, according to Yahoo Finance on September 22, 2026. The fiscal first-quarter outlook called for revenue of USD 8.1 billion, plus or minus USD 400 million, and a non-GAAP operating margin of 39.5 percent, plus or minus 1 percentage point.

That guidance implies a further 1.1 percentage-point increase from the fiscal fourth-quarter margin midpoint. The counter-factor is valuation: the same coverage placed Lam Research at a forward price-to-earnings ratio of 30.85, while the cited industry average was 13.52.

Shares gain while dividend turns ex-date

Lam Research shares were also affected by the quarterly dividend schedule. On September 23, 2026, the stock traded ex-dividend for USD 0.33 per share, according to Placera. The payment represents an increase from the previous quarterly dividend of USD 0.26 per share.

For investors, the key numerical tension is clear: fiscal fourth-quarter revenue grew 30 percent year over year, while the forward valuation cited by Yahoo Finance stood at more than twice the sector average. Execution against the USD 8.1 billion revenue outlook therefore remains central to the stock narrative.
