Key Takeaways:
Texas Instruments and STMicroelectronics delivered strong quarterly results, yet both stocks sold off — a sign that record-high valuations have left analog semiconductor stocks with zero room for error.
STMicroelectronics plunged as much as 17% in European trading after its third-quarter revenue forecast of about $3.7 billion missed the $3.9 billion consensus, punishing a stock that had already rallied 119% this year. Texas Instruments fell about 3% despite beating on both earnings and revenue, as investors focused on capital expenditure guidance that could delay a free cash flow recovery.
"We believe the lack of material upgrades in this report will pressure the stock relative to the market," UBS analyst Francois-Xavier Bouvignies said, noting STM had gained 35% in the prior three months alone.
Texas Instruments posted adjusted EPS of $2.14, up 52% from a year earlier and above the $1.94 consensus, while revenue rose 23% to $5.46 billion, topping the $5.26 billion estimate. STM's adjusted EPS more than doubled to 31 cents, and revenue climbed 26% to $3.49 billion — both slightly ahead of analyst targets. The problem was what came next. TXN Chief Financial Officer Rafael Lizardi told analysts that capital expenditure could land at the high end of the $2 billion to $3 billion range, pressuring expectations for a near-term free cash flow inflection. STM's Q3 guidance of roughly $3.7 billion fell short by about $200 million, with the company flagging below-seasonal trends in personal consumer electronics.
The divergent reactions — solid fundamentals, punishing stock moves — expose a structural risk across the analog semiconductor sector. With TXN up 60% and STM up 119% year to date, markets have priced in perfection. Any deviation from the optimistic script triggers rapid de-risking.
AI Demand Is Real, But So Is the Valuation Problem
Both companies pointed to AI infrastructure as a powerful demand driver. STM Chief Executive Officer Jean-Marc Chery said fourth-quarter revenue will exceed $4 billion, up more than 20% from a year earlier, driven by AI data centers and low-earth orbit satellite communications. The company raised its 2026 AI-related revenue target to more than $1 billion — the second upgrade since it began disclosing the metric in April — and expects that figure to surpass $2 billion in 2027.
Texas Instruments reported data center demand growing rapidly, with industrial sales rising at least 30% and automotive revenue posting mid-teens percentage growth. Bloomberg Intelligence analyst Charles Shum noted that rising AI rack power levels are driving a new growth cycle for STM's power semiconductor business. STM's power management chip supply agreement with Amazon Web Services will contribute revenue for three to five years, Chery said.
The fundamental recovery in analog semiconductors — spanning AI infrastructure, industrial end-markets, and automotive — remains intact. But the valuation math has shifted. Cantor analyst Matthew Prisco said TXN's "elevated expectations" combined with concentrated long positioning made the post-earnings selloff rational, even on a beat-and-raise quarter.
For investors, the question is whether the selloff creates an entry point or signals more pain ahead. STM trades at elevated multiples after its 119% rally, and TXN's capex trajectory means free cash flow improvement may take longer than the market anticipated. Mizuho has recommended buying the STM pullback, but the sector's core challenge remains: when stocks are priced for perfection, even good news is no longer good enough.
