Arm Falls 3.27% as Qualcomm’s Royalty Suit Reaches a Jury That Has Not Yet Ruled
A Delaware federal jury deliberated about four hours on Friday without a verdict in Qualcomm’s suit against Arm and resumes on Tuesday, per Reuters via The Star. Jurors are deciding whether Arm breached its licenses by withholding software patches and tools, whether it violated a clause capping Qualcomm’s price at 10% above Arm’s lowest price for comparable technology, and whether it hurt Qualcomm’s Meta dealings by leaking a 2024 letter. Qualcomm seeks to suspend royalties for up to five years, a remedy Tech Times put at about $1.5 billion on analyst estimates of roughly $300 million a year; Judge Maryellen Noreika has not ruled on whether that clause is enforceable. Arm closed Friday at $266.28, down 3.27%, and Qualcomm at $175.50, down 0.29%, per StockAnalysis.
"Qualcomm’s entire chip business depends on Arm and on Arm honoring its contract." — Karen Dunn, attorney for Qualcomm, in her opening statement, via Tech TimesDunn’s line is about dependence, but the payment arithmetic runs the other way. Yahoo Finance calculated Qualcomm’s contribution to Arm at $443 million, 9% of the $4.92 billion Arm booked in the fiscal year ended March 31, 2026, which equals about 49% of Arm’s $908 million of operating income but about 4% of Qualcomm’s $10.43 billion of trailing operating income; the article calls the $443 million a scale comparison, not an estimate of the disputed royalties. On ChipSentinel’s reading, the clause ruling matters more to Arm’s income statement than to Qualcomm’s: if Noreika voids it, Qualcomm is left with conventional damages rather than the royalty holiday, and Qualcomm says the leaked letter cut the value of its Meta deal by $170 million. A separate bench trial on whether Arm negotiated ARMv10 pricing in good faith will be decided later, and the FTC probe described below is independent of the jury.

Skyworks Slides 5.45% After Closing Qorvo as Texas Instruments Nears Its October 21 Report
- Skyworks closed Friday at $76.35, down 5.45%, per StockAnalysis, and MarketBeat (October 9) cited no cause for the decline, noting a consensus rating of Hold and an average target of $78.74, about 3.1% above the close. The company completed its combination with Qorvo, with each Qorvo share converted into $32.50 in cash plus 0.960 of a Skyworks share, targeting at least $500 million of annualized savings within 24 to 36 months, per Pulse 2 (October 5). Why it matters: no company-specific disclosure was cited for Friday’s drop, so on ChipSentinel’s reading the savings schedule and the 63% and 37% legacy-holder split, not a new datapoint, are what the market is now pricing.
- Texas Instruments closed Friday at $283.74, down 1.55%, ahead of third-quarter results on October 21, per StockAnalysis, with consensus revenue of $5,908 million and EPS of $2.42 against guidance of $5,650 million to $6,150 million and $2.23 to $2.57, per Hudson Labs (October 5). The preview puts consensus gross margin at 61.8%, says management confirmed price increases in the third quarter that continue into the fourth quarter and 2027, and shows inventory of $4.6 billion, or 196 days, down 13 days from the prior quarter. Why it matters: the analog cycle is being underwritten on pricing and inventory normalization rather than AI demand, and consensus revenue sits just below the $5,900 million midpoint of the guided range.

CXMT Shows a 4F DRAM Cell Design as the Memory ETF Sits Nearly 30% Below Its High
- CXMT president Cao Kanyu discussed a next-generation DRAM architecture built on a "4F square" cell at a Shanghai industry event over the weekend, with a server-memory product planned by the end of 2026, per Stocktwits via Yahoo Finance (October 12), citing the South China Morning Post; Micron dipped about 1% overnight and SK hynix about 0.8% in local trading, and in premarket trading Micron was at $1,004.74, down 2.36%, and SK hynix’s U.S. listing at $165.48, down 2.10%, per StockAnalysis and StockAnalysis. Why it matters: SK hynix unveiled its own 4F roadmap in 2025 and Samsung targets mass production by 2028, so the news is a claim of technical parity by a Chinese rival whose fifth-generation platform entered mass production last month, but no specifications or launch date were disclosed.
- The Roundhill Memory ETF (DRAM) slid to $57.19, nearly 30% below its 2026 high, and lost more than $1.62 billion of assets over 30 days, leaving about $24 billion, per Benzinga (October 10), which put forward price-to-earnings multiples at about 8 for Micron and 7.5 for SanDisk and Micron’s average analyst target at $1,463, about 42% above the price it cited. Why it matters: the article lists OpenAI’s revenue reset and faster cash burn at AI companies among the risks, and on ChipSentinel’s reading, multiples that low against the profit growth the article cites suggest investors are pricing the cycle’s peak rather than current earnings.

ASML Guides €11 Billion to €12 Billion Into Wednesday as Infineon Scales a Bangkok Site
- ASML reports third-quarter results on Wednesday, October 14, against guidance of €11 billion to €12 billion of revenue and a 55% to 57% gross margin, with consensus near €11.6 billion to €11.8 billion, up about 55% from a year earlier, per TradingKey (October 12), which cited a consensus ADR EPS of about $12.47 and full-year 2026 guidance of €43 billion to €45 billion, raised from €36 billion to €40 billion. TradingKey (October 11) said a Hyper-NA lithography paper from ASML and Carl Zeiss engineers points to operation around 2036 with production not committed. Why it matters: consensus revenue already sits inside the guided range, and the preview names EUV and High-NA order changes, for which it gives no consensus bookings figure, as the swing factor for the shares.
- Infineon closed Friday at €59.01, up 1.0% after a 5.5% fall on Wednesday and an 8.7% decline over seven days, per ad-hoc-news (October 10), which also reported a back-end site in Bangkok that can scale to five modules in stages and lift the Thai workforce from about 350 to about 1,000; fiscal fourth-quarter results are due November 10. Why it matters: the article says elevated rates and a subdued economy could make industrial customers reluctant to commit capital and that classic segments face cyclical softness, so back-end capacity is being added into a cohort that sold off without a reported change in orders.

The FTC Arm Probe Runs Outside the Verdict as a Super Micro Contractor Pleads Guilty
- The FTC opened an antitrust investigation into Arm in May 2026 over whether its licensing practices illegally monopolize parts of the chip market, and it runs independently of the Delaware jury, per Tech Times (October 9), which said complaints by Qualcomm to the FTC, the European Commission and South Korea’s Fair Trade Commission helped trigger it, after Arm launched its own chip in March that competes with licensees; the probe was first reported by Bloomberg (May 15). Why it matters: a verdict for or against Arm leaves the regulatory question open, which on ChipSentinel’s reading keeps a second source of risk on a royalty model that licensees, Qualcomm among them, pay into.
- Ting-Wei "Willy" Sun, a contractor linked to Super Micro Computer, pleaded guilty on Thursday in Manhattan federal court to a scheme to illegally export servers, per Reuters via Investing.com (October 9); prosecutors charged Sun and two others in March with conspiring to divert about $2.5 billion worth of U.S. AI technology to China. Why it matters: the report cited no share reaction and no Super Micro statement, so the exposure is to enforcement scrutiny of server channels that carry Nvidia chips rather than to any measured revenue loss.

Jack Gold Flags Arm’s Licensor-Competitor Tension as Stifel Expects a TSMC Guidance Lift
- Jack Gold of J. Gold Associates said the Qualcomm dispute raises competitive questions "whenever you both license technology IP and use it yourself to compete with your licensees," per Tech Times (October 9), which noted Arm launched its own AGI CPU in March 2026 and that Qualcomm’s architecture license runs through 2033.
- Stifel reiterated Buy on TSMC with a $515 target and expects the October 15 call to bring fourth-quarter guidance that lifts the full-year outlook, per Investing.com (October 9); year-to-date growth of 41.1% already exceeds the company’s "slightly-above-40%" full-year guidance, and Stifel estimates a flat fourth quarter implies about 42% annual growth against about 45% for an average seasonal quarter.
