Micron's stock soared 16.4% in premarket trading on Thursday following the release of its third-quarter earnings, which were significantly boosted by surging demand for memory chips driven by the AI boom [1]. The company reported revenue of $41.46 billion for the fiscal third quarter, more than quadrupling from $9.3 billion a year earlier and surpassing analyst expectations of nearly $36 billion according to LSEG consensus estimates [1]. Micron has raised its revenue forecast for the current quarter to about $50 billion, up from $11.3 billion in the prior year [1]. Over the past year, Micron's stock has risen 723%, pushing its market capitalization to $1.2 trillion [1].
Micron has benefited from the AI infrastructure buildout by major hyperscalers, as AI data centers require large amounts of memory chips. This has created a supply imbalance, reducing the availability of memory for smartphones, PCs, and other devices, which in turn has pushed memory prices higher and boosted Micron's results [1]. The company announced it has signed 16 long-term agreements with customers ranging from data centers to automakers, locking in sales for three to five years and expecting financial commitments of $22 billion from these contracts [1]. RBC Capital Markets analysts noted that about 40% of Micron's revenue is expected to come from long-term contracts with minimum prices built in, which should help limit margin risk even if demand weakens during the contract term [1].
RBC Capital Markets analysts expressed confidence in the sustainability of the current upcycle, stating, "Our base case is for current upcycle to continue through 2027, and SCAs give us added conviction regarding sustainability. We raise estimates, raise PT, and reiterate Outperform" [1]. Micron's strong earnings have also lifted global tech stocks, reversing a sharp selloff earlier in the week that affected companies such as Intel, Nvidia, and AMD [1]. In premarket trading on Thursday, Qualcomm was up 12%, Intel nearly 6%, AMD 3.6%, and Nvidia 1.5% [1].
Capital.com Senior Market Analyst Daniela Hathorn commented that Micron's earnings provide reassurance that the AI investment cycle remains firmly intact, with robust demand for memory from data centers and AI infrastructure customers reinforcing the narrative of accelerating capital spending on AI [1]. Hathorn added that this has helped lift sentiment across the semiconductor sector after recent weakness, suggesting investors are willing to look through short-term volatility as long as the earnings outlook justifies elevated valuations [1].
CONCLUSION
Micron's blockbuster earnings and raised forecast, driven by AI-related demand, have sparked a strong rally in its stock and lifted sentiment across the semiconductor sector. Long-term contracts and analyst optimism point to sustained growth and reduced margin risk. The market takeaway is that the AI investment cycle remains robust, supporting elevated valuations for semiconductor stocks.
