Key Highlights

● FormFactor shares were down 7.74% to $89.92 in pre-market trading on Oct. 30.

● Third-quarter Revenue hit a record $280.5 million, up 38.4% year over year.

● Fourth-quarter guidance points to slower growth, lower Margin and lower EPS.

● A global chip sell-off is adding pressure after Intel's weak outlook.

FormFactor (NASDAQ:FORM) is extending its post-earnings slide before Friday's open. A pre-market movers table, in a snapshot updated at 8:23 a.m. ET on Oct. 30, had the stock at $89.92, down 7.74%. A market data provider listed a previous close of $97.46.

An automated news note calls it a sell-the-news reaction and mentions margin concerns tied to Tariff refunds. The tariff-refund point could not be found in the company's results as summarized by a market data provider, so that detail is unconfirmed. Such notes may not reflect the direct cause of a move. What is clear is that the stock is falling on a day when chip stocks around the world are under heavy selling.

What FormFactor reported on Oct. 28

Livermore, California-based FormFactor makes probe cards, the precision interfaces that test chips while still on the wafer, along with probe stations and cryogenic systems used in Quantum Computing research. Its products sit right in the path of AI chip and high-bandwidth memory production.

Third-quarter revenue reached $280.5 million, the company's fourth straight quarterly record, up 8.6% from the second quarter and 38.4% from a year earlier, according to the summary. GAAP Net Income jumped to $73.8 million, or $0.93 a share, from $15.7 million, or $0.20. GAAP gross margin widened to 54.7% from 39.8%. Operating Cash Flow was $104.3 million and free cash flow $64.8 million.

The guidance is where some investors may have paused. For the quarter ending Dec. 26, FormFactor expects revenue of $285 million, plus or minus $10 million, GAAP gross margin of 52.3%, plus or minus 1.5 points, and GAAP EPS of $0.84, plus or minus $0.09. That points to slower growth, a lower margin and lower EPS than the third quarter. The company also said "productivity gains are moderating as existing factories approach capacity limits," and its new Farmers Branch, Texas, plant, opened Oct. 22, is just coming online.

That mix of peak-looking margins and capacity constraints is a classic setup for profit-taking, especially after a strong run into the print.

Index, sector and what comes next

FormFactor trades on the Nasdaq and is part of the Nasdaq Composite. An index provider said on Oct. 1 that it was among companies being moved within its index family, with a summary pointing to a shift into the S&P MidCap 400. That reflects how much the company's market value, roughly $7.6 billion before today, has grown.

The sector backdrop is rough. Intel (NASDAQ:INTC) guided fourth-quarter revenue to $15 billion to $16 billion, below the consensus of $17.07 billion, and its shares were down about 25% pre-market. One report said Nvidia (NASDAQ:NVDA), AMD (NASDAQ:AMD), Broadcom (NASDAQ:AVGO) and Micron (NASDAQ:MU) were down between 2% and 9%. In Asia, SK hynix fell 8.3% and Tokyo Electron dropped more than 5%, according to market data. Nasdaq-100 futures were down 2.62% at about 8:03 a.m. ET, per market quotes.

Investors also worry that hyperscalers will rein in AI capex after Amazon (NASDAQ:AMZN)'s $220 billion plan and negative free cash flow. Fewer new AI chips would ultimately mean fewer probe cards.

Key risks for FormFactor include memory customers' spending swings, capacity bottlenecks before the Texas plant ramps, and gross margin pressure from new-factory costs. Its Oct. 12 collaboration with Teradyne (NASDAQ:TER) on next-generation testing is a longer-term positive to watch.

Near-term catalysts include next week's AMD and Qualcomm (NASDAQ:QCOM) results, Apple (NASDAQ:AAPL) on Nov. 2, and any comments from memory makers on high-bandwidth memory demand. Whether the stock stabilizes near $90 after the opening bell will show whether today's move is mostly sector-driven or a deeper reset of expectations after a record run.
