Key Highlights

● Veeco traded at about $42.00 in premarket trading on October 22.

● The premarket figure is a snapshot, and no closing price was available.

● Lam guided December-quarter revenue to $8.6 billion, plus or minus $400 million.

● Needham cut its Lam price target to $290 from $390.

Veeco Instruments (NASDAQ:VECO) slid on Thursday, October 22, 2026, as semiconductor-equipment stocks retreated in the wake of Lam Research (NASDAQ:LRCX)'s results. The stock, a member of the S&P SmallCap 600, traded at about $42.00 before the opening bell.

That premarket figure is a snapshot taken before the regular session began, and no closing price for the stock was available in the reports. The move, which tracked the broader chip-tool selloff, came without company-specific news.

The Lam warning

The selling in equipment names began with Lam Research. Late on Wednesday, Lam reported record revenue of $8.22 billion and adjusted earnings of $2.20 per share, but its December-quarter guidance of $8.6 billion, plus or minus $400 million, had a midpoint slightly below consensus.

Lam also warned about supply. Upstream parts shortages and certified clean-room constraints "continue to curb manufacturing velocity" and will persist into 2027, the company said.

Lam's chief financial officer said "things are going to continue to be constrained," while Lam's chief executive said the constraints would "limit chip makers and equipment companies' ability to fully meet end demand." China, which made up a large share of Lam's September-quarter sales, was guided "meaningfully down."

Veeco's place in the chain

Veeco is a semiconductor-equipment supplier, and a warning from an industry bellwether that production velocity will remain constrained tends to weigh on the whole group.

A sector in retreat

Veeco had plenty of company. Lam Research plunged during the regular session, KLA (NASDAQ:KLAC), Applied Materials (NASDAQ:AMAT) and ASML (NASDAQ:ASML) all fell sharply, and chip-test names Teradyne (NASDAQ:TER), FormFactor (NASDAQ:FORM) and Cohu (NASDAQ:COHU) also sank. Needham cut its price target on Lam to $290 from $390, and Morgan Stanley trimmed its target to $339.

The Philadelphia Semiconductor Index suffered its biggest one-day drop since June 23, though it closed just above its 200-day moving average.

Meta and the AI financing worry

The chip selloff was magnified by the report from Meta Platforms (NASDAQ:META). Meta's 2026 capital spending range of $135 billion to $145 billion and its negative free cash flow raised questions about the cost of the AI build-out. Nvidia (NASDAQ:NVDA)'s chief executive added to the worries, saying, "The demand of the capital is much greater than the availability of the capital."

The Nasdaq Composite dropped 694.00 points to 26,008.86, its steepest fall since June 5, and the S&P 500 lost 93.74 points to 7,663.43, its worst day since July. Trading was heavy, with 18.79 billion shares changing hands on US exchanges against an average of 17.19 billion over the prior 20 sessions, according to market data.

Outside tech, the picture was brighter. The Russell 2000 edged up 3.01 points, the Dow Jones Industrial Average finished essentially flat, and about two of every three S&P 500 stocks rose, according to market reports. Treasuries rallied, sending the 10-year yield back below a closely watched threshold for the first time since September 22.

Veeco Watches Orders and Customer Plans

For Veeco, investors will look for any update on order trends and whether customers are adjusting their plans in response to the supply constraints Lam described.

The broader chip sector faces a crucial stretch. Teradyne reports on October 27, Microsoft (NASDAQ:MSFT) and Alphabet (NASDAQ:GOOGL) on October 28, and Amazon (NASDAQ:AMZN) and Intel (NASDAQ:INTC) on October 29. Their results and spending plans will help show whether Thursday's retreat in chip-tool stocks deepens or reverses.
