Intel Shares Sink 6% After Parabolic Run as Altera IPO Plans Emerge

Intel shares fell roughly 6% to around $99.67 on Thursday, September 10, reversing course after a five-session winning streak that had lifted the stock more than 20%, as profit-taking, a broader chip sector selloff and a new neutral rating from Piper Sandler combined to pressure the name. The Nasdaq 100 dropped 1.28% to a one-week low on the day, with oil surging past $105 a barrel and Treasury yields climbing to three-year highs adding to the risk-off tone across semiconductor stocks, with Nvidia and AMD each retreating roughly 3%.

The prior rally had been fueled in part by reports that Intel may raise chip prices by as much as 10% and by updates to its server processor roadmap, but skepticism ran deep among Wall Street analysts who largely declined to upgrade the stock. Piper Sandler initiated coverage at Neutral citing valuation concerns, and a fair-value model published by Investing.com flagged 43.9% downside from recent levels. Seeking Alpha noted that Intel's forward EV/EBITDA had risen to 25.83x, reflecting a 16% share price gain and 4.8% dilution from a $22.6 billion equity raise the company completed to fund new fabrication plants without taking on additional debt.

The most significant longer-term development came after the close, when Reuters reported that Altera, the programmable-chip maker majority-owned by Silver Lake and 49%-owned by Intel, is preparing an IPO that could raise more than $2 billion as early as 2026. Barclays, Citi, JPMorgan and Morgan Stanley have been tapped as underwriters, and a confidential filing is expected in the coming weeks. Intel originally acquired Altera for $16.7 billion in 2015 before selling a 51% stake to Silver Lake in a deal that valued the company at $8.75 billion. Altera makes programmable chips for data centers, telecom, industrial, aerospace and defense, and AI applications, and the offering would rank among the largest semiconductor listings since Arm's 2023 debut.

Additional headwinds for Intel included Nvidia's push into server CPUs with its Vera chip, which analysts said put both Intel and AMD on the defensive, as well as billionaire investor Stanley Druckenmiller's disclosed exit from his Intel position. On a more constructive note, ASML expanded its High-NA lithography ties with Intel and Samsung as AI infrastructure demand builds, and an Intel-backed startup called Kepler Computing drew attention for its ambitions to disrupt the memory-chip market, contributing to pressure on Micron shares.
